Description

Technical Field

[0001] This application relates to the field of poultry restraint devices, and in particular to a poultry restraint device and a restraint method. Background Art

[0002] In the livestock and poultry industry, when selecting, mating, and breeding poultry, processing operations such as vaccine injection, sex identification, disease diagnosis and treatment are required. Therefore, it is necessary to restrain poultry. However, due to the special nature of live poultry being extremely prone to struggling and moving, it is very difficult to restrain and fix them. Especially for young chicks, it is necessary to effectively restrain them without harming the poultry. Currently, the restraint and processing of poultry are usually carried out manually, with low efficiency and heavy workload, so the labor cost is relatively high.

[0003] In some technologies, the limbs and / or head are restrained through equipment to achieve partial fixation of the poultry, thereby improving the processing efficiency. However, this method is only applicable to the operations of processing the fixed parts and cannot be applied to the processing operations of other parts (such as the body part). Moreover, there is still a problem that the poultry struggles and affects the fixation, thus affecting the accuracy of the operation. For some operations that require precise positioning, such as the operation of inserting an instrument into the cloaca of the poultry, manual assistance is still required at present, and it is difficult to improve the efficiency.

[0085] In the livestock and poultry industry, during the cultivation process of poultry, relevant processing operations need to be performed on the poultry, including but not limited to: various types of operations such as in-vivo and in-vitro injections, identification and discrimination, diagnosis and treatment, etc. When performing these operations, the poultry needs to be restrained. Currently, it is generally done manually, but the efficiency is low, the workload is large, and the cost is relatively high. In some technologies, mechanical equipment is used to carry the poultry and fix its limbs and / or head to achieve partial fixation of the poultry, so as to perform corresponding operations on the fixed parts, thereby improving the processing efficiency. However, there is still a problem that the poultry struggles and affects the fixation, thus affecting the accuracy of the operation. There are also some devices that add a body cover plate to cover the back of the poultry, which can restrain the movement of the body within a relatively small range of movement. However, there will still be problems such as body twisting or deviation, and it cannot meet some operations that require precise positioning. If the restraint force on the limbs, head, or back is simply increased on this basis to limit the movement of the poultry, it may cause the poultry to be injured.

[0086] The embodiments of the present application provide a restraint solution for poultry with reference to the distribution and characteristics of poultry bones. Specifically, a femur restraint mechanism is proposed, which can restrain the position of the femur of the poultry, thereby effectively restraining the body of the poultry. It can be understood that the bones of poultry are characterized by light weight and high strength, with a dense bone density. They can be divided into the head, body bones, forelimb bones (or wing bones), and hindlimb bones. Among them, the femur of the poultry is located on both sides outside the body, forming a relatively obvious convex structure and having a definite position. And for poultry, on the premise that the position of the femur is effectively restrained, the swing of its head, forelimbs, or hindlimbs has little impact on the body position. Therefore, through the restraint of the femur of the poultry in the embodiments of the present application, effective limitation of the body can be achieved, which helps the smooth progress of subsequent various processing operations and is applicable to processing operations such as in-vivo and in-vitro injections, identification and discrimination, diagnosis and treatment, etc. in poultry cultivation.

[0087] The first aspect embodiment of the present application provides a poultry restraint device, including a body restraint device. The body restraint device includes a femur restraint mechanism configured to restrain the femurs on both sides of the poultry body in a first direction and / or a second direction. By the femur restraint mechanism abutting against the femurs on both sides of the poultry body in the first direction and / or the second direction, the determination of the femur position can basically determine the position of the body, avoiding the problem of the body position shifting caused by the struggling of the poultry head, thus facilitating the smooth progress of subsequent processing operations, especially applicable to the processing operations of the internal and external parts of the body part.

[0088] The poultry restraint device further includes at least one of the following:

[0089] A head restraint mechanism disposed on one side of the body restraint device along the first direction, configured to restrain the head of the poultry at least in the first direction away from the poultry body, so that the femurs of the poultry can abut against the femur restraint mechanism, thereby cooperating with the femur restraint mechanism to restrain the femur position of the poultry;

[0090] A pushing device disposed on the side of the femur restraint mechanism away from the head, configured to push the body of the poultry at least in the first direction, so that the femurs of the poultry can abut against the femur restraint mechanism, thereby cooperating with the femur restraint mechanism to restrain the femur position of the poultry;

[0091] A second restraint member disposed adjacent to the femur restraint mechanism along the first direction, and the second restraint member is configured to cooperate with the femur restraint mechanism to restrain the femur position of the poultry.

[0092] Thus, the femur restraint mechanism cooperates with at least one of the head restraint mechanism, the pushing device and the second restraint member to adjust the position of the poultry body to abut the femurs against the femur restraint mechanism, realize the restraint of the femur position, improve the restraint accuracy, and thus facilitate the smooth progress of subsequent processing operations.

[0093] Reference Figures 1 to 5 , in some embodiments, the femur restraint mechanism 500 includes a first restraint member 510. The first restraint member 510 is provided with two first abutting portions 511. The interval between the first abutting portions 511 can accommodate the body of the poultry. The first abutting portions 511 can abut against the side of the femur of the poultry facing the head to realize the restraint of the femur position. The position of the femur is determined and has sufficient strength. Compared with the currently commonly used schemes of fixing by limbs and / or head, and compared with the restraint scheme of covering the back of the poultry with a cover plate to limit the activity range of the poultry body, it can realize the direct restraint of the body and improve the accuracy of poultry body positioning.

[0094] From the characteristics of the bone distribution of poultry, it can be seen that the femur of poultry can form obvious convex features 804 on both sides of the body. Due to the convex feature 804 at the position of the femur, the first abutting portion 511 can be placed on the side of the femur facing the head. Thus, the first abutting portion 511 can abut against the femur on the side of the femur facing the head, or the first abutting portion 511 can be provided with a clamping structure to clamp the femur at a set position, so as to realize the restraint of the femur in this direction.

[0095] To assist in explaining the restraint of the position of the femur of poultry by the femur restraint mechanism 500, refer to Figure 4 and Figure 5 in which an outer contour model 800 of poultry is used as a reference. The model 800 shows the body 801, neck 802, hind limb femur 803, etc. of the poultry, and an X-Y-Z rectangular coordinate system is introduced as a direction reference. Among them, the direction of the body facing the head is the Y-axis, the direction of the body from the chest and abdomen towards the back is the Z-axis, and the direction of the body from left to right is the X-axis. The direction of the Y-axis is the first direction, the direction of the X-axis is the second direction, and the direction of the Z-axis is the third direction. The hind limbs are located on both sides of the body in the second direction. The femur is the skeleton of the hind limb. Therefore, due to the convex feature 804 of the femur, the dimension in the second direction is larger than the dimension of the body part around the femur. Therefore, the first abutting portion 511 can be placed on one side of the femur in the first direction and can abut against the femur on one side of the femur in the first direction, so as to limit the position of the femur in the first direction and realize the restraint of the femur in the first direction. Or, in some embodiments, the first abutting portion 511 can also be set to be able to abut against the femur in both the first direction and its negative direction, so as to limit the position of the femur in the first and second directions.

[0096] In the above embodiments, the first restraint member 510 can adopt various structures, which can be plate-shaped, rod-shaped, block-shaped, etc., and can be a single component or a combination of multiple components. As long as a pair of first abutting portions 511 are formed in the structure and can be used to restrain the position of the side of the femur of poultry facing the head, or the formed first abutting portions 511 can restrain the position of the femur on both sides of the femur facing the head or away from the head. A pair of first abutting portions 511 can be defined to form a figure-eight shape, an arc shape or a profiling structure. The following provide some specific embodiments:

[0097] Refer to Figures 1 to 5, in some embodiments, the first restraint member 510 includes two clamping members 512. On the sides of the clamping members 512 facing each other, there are first abutting portions 511. The femur restraint mechanism 500 further includes a driving mechanism 520. The driving mechanism 520 can drive the clamping members 512 to move so as to adjust the distance between the two first abutting portions 511. By moving the clamping members 512, the first abutting portions 511 can respectively abut against or approach the side of the poultry. During operation, the poultry can be placed between the two clamping members 512. When placed, the femur of the poultry is correspondingly located on the side of the clamping members 512 away from the head. Therefore, when restraining the poultry, this femur restraint mechanism 500 can be used to restrain the position of the femur of the poultry and thus achieve the restraint of the body part. Compared with the solution of restraining the poultry by restraining the head, neck, forelimbs or hindlimbs, restraining the position of the femur can more accurately determine the body position of the poultry, which is beneficial for performing some precise operation processes. Among them, the two clamping members 512 can be two plate-shaped, block-shaped or rod-shaped members. The edges on the sides of the two clamping members 512 facing each other are the first abutting portions 511. The first abutting portions 511 of the two clamping members 512 that move towards or away from each other under the drive of the driving mechanism 520 can approach or move away from each other. Thus, after the first abutting portions 511 of the two clamping members 512 approach the body from both sides corresponding to the position of the femur facing the head, the first abutting portions 511 of the two clamping members 512 can respectively form limits to restrict the position of the femur in the direction towards the head. The two first abutting portions 511 can at least restrict the position of the femur in the first direction in the first direction, so as to at least form a restraint on the body in the first direction.

[0098] Reference Figures 1 to 3, in some embodiments, on the sides of the snap members 512 facing each other, there are further provided protrusions 513. The protrusions 513 are located at one end of the first abutting portion 511 and protrude towards the direction between the two snap members 512. The side edge of the protrusion 513 facing the first abutting portion 511 is the second abutting portion 514. The second abutting portion 514 can abut against the femur on the side of the femur facing the head, or restrict the movement of the body in the back direction of the poultry. It can be understood that the femur of the poultry forms a convex feature 804 at one end of the body, and the convex feature 804 has an irregular outer contour surface. By providing the protrusion 513 on the snap member 512 to form the second abutting portion 514, the first abutting portion 511 and the second abutting portion 514 can abut against the femur at different positions in the circumferential direction around the body respectively to enhance the restraint effect. The two first abutting portions 511 and the two second abutting portions 514 can at least restrict the position of the femur in the first direction in the first direction, and the first abutting portion 511 and the second abutting portion 514 can abut against the femur at different positions around the third direction, so as to be able to form a restraint on the body at least in the first direction. In addition, since the protrusion 513 on the snap member 512 protrudes from the first abutting portion 511, the gap between the second abutting portions 514 is smaller. Therefore, a limit can be formed in the third direction of the poultry to prevent the poultry from detaching from the snap member 512 in the third direction. The position of the protrusion 513 on the snap member 512 can be reasonably set according to the size of the body of poultry of different body types, so as to be applicable to poultry of different body types.

[0099] In some embodiments, the first abutting portion 511 can be arc-shaped or irregularly curved, or can be linear along the third direction (refer to Figure 2 ), or can also be a profiling structure adapted to the outer contour of the body of the poultry. Among them, for the restraint of chicks, the minimum distance between the two first abutting portions 511 can be configured to be 10 mm to 14 mm, such as 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or other values between 10 mm and 14 mm. Configuring the minimum distance between the two first abutting portions 511 to be 10 mm to 14 mm can be applicable to the body restraint of most normal chicks. The femur restraint mechanism 500 sets the structure and movement of the first restraint member 510 with this size as a reference, which can better be applicable to the femur restraint of chicks, reduce the probability of restraint failure, and thus improve the processing effect of chicks. Of course, according to poultry of different body types, the minimum distance between the two first abutting portions 511 can also be adaptively configured, which will not be elaborated here.

[0100] Refer to Figure 6, in some embodiments, the two engaging members 512 on the first restraint member 510 may not be provided with the above-mentioned protrusions 513. On the sides of the two engaging members 512 facing each other, there are provided inclined first abutting portions 511, and the two are inclined towards each other to form a structure in which the spacing on one side increases from one side to the other side. Thus, a receiving space similar to an inverted V-shape is formed between the two engaging members 512. The inclined first abutting portions 511 can adapt to the dimensions of poultry of various body types in the second direction, thereby improving the adaptability of the femur restraint mechanism 500.

[0101] Based on the above idea, in some embodiments, the first restraint member 510 may also be a single component. For example, refer to Figure 7 , the first restraint member 510 of the femur restraint mechanism 500 may be a single plate member. A notch capable of accommodating the body of the poultry is formed on the first restraint member 510. The opposite side edges of the notch form the above-mentioned pair of first abutting portions 511. During operation, it is necessary to place the first restraint member 510 corresponding to the position of the femur facing the head close to the body from the back or chest and abdomen and place the body in the notch. Then, the two first abutting portions 511 on the edge of the notch can respectively form limits to restrict the position of the femur in the direction towards the head. The two first abutting portions 511 on the edge of the notch can at least restrict the position of the femur in the first direction along the first direction, thereby being able to form a restraint on the body at least in the first direction. It can be understood that the width of the body along the second direction at the front position of the femur of the poultry in the first direction is defined as the reference width. The width of the notch along the second direction can be reasonably configured according to the possible width dimension of the body at this position of the poultry to be operated, and can be made slightly larger than the reference width, so as to avoid pinching or scratching the body of the poultry, and ensure that the width of the notch is smaller than the width of the convex positions of the femurs on both sides in the second direction, so as to ensure that the first abutting portions 511 of the plate member can abut against the femur at least in the first direction. Among them, in the femur restraint mechanism 500, the first restraint member 510 is detachable and replaceable. Thus, according to the above reference widths of different poultry of different body types, a plurality of first restraint members 510 with corresponding notch widths can be configured, so as to adapt to the restraint of different poultry of different body types by replacing the first restraint member 510, which is convenient for carrying out relevant processing operations, has a simple and feasible structure, and can assist in restraining the body of the poultry, improving the efficiency of poultry processing operations.

[0102] In some embodiments, a clamping groove is further provided on the first abutting portion 511. The openings of the clamping grooves face each other, and the width of the clamping groove can accommodate the convex portion of the femur, so that the femur can be clamped at a set position, thereby accurately defining the position of the body. When the position of the femur is constrained by the first constraint member 510, the clamping groove is used to accommodate the convex portion of the femur, such as the hip joint position, so that the position of the femur can be constrained on both sides in the first direction, thereby optimizing the constraint effect of the body and improving the poultry processing efficiency and accuracy. Among them, the clamping groove can be formed in a variety of ways. For example, for the first constraint member 510 with a plate-like or block-like structure, a groove can be opened on the first abutting portion 511 to form groove openings facing each other. Or, the first constraint member 510 can be set as a structure in which two spaced double-layer plates are connected, and a clamping groove is formed by setting a set distance between the two layers of plates, or formed by other means.

[0103] In the above-mentioned some embodiments, in the solution where the driving mechanism 520 drives the two clamping members 512 to move to change the distance between the two first abutting portions 511, it can be that one of the clamping members 512 is connected to the driving mechanism 520 and is driven by the driving mechanism 520 to approach or move away from the other clamping member 512. Among them, the driving mechanism 520 can adopt a linear driving mechanism commonly used in automation equipment, such as a cylinder, a hydraulic cylinder or a linear module, etc. Or, it can also be that the two clamping members 512 are both connected to the driving mechanism 520, and the driving mechanism 520 drives the two clamping members 512 to move towards or away from each other respectively. Among them, the driving mechanism 520 can adopt a linear driving mechanism commonly used in automation equipment, such as a cylinder, a hydraulic cylinder or a linear module, etc. Or, it can also be that the two clamping members 512 are both connected to the driving mechanism 520, and the driving mechanism 520 drives the two clamping members 512 to move towards or away from each other simultaneously. The driving mechanism 520 can adopt a bidirectional driving mechanism commonly used in automation equipment, such as a double-acting cylinder, a double-acting slide module or a bidirectional lead screw mechanism driven by a motor, etc.

[0104] Reference Figures 8 to 10 , in some embodiments, the femur constraint mechanism 500 further includes a linkage mechanism 530 and two mounting seats 540. The two clamping members 512 are connected to the two mounting seats 540 in one-to-one correspondence. Each clamping member 512 and a corresponding mounting seat 540 can be detachably connected in a split manner, or can be made into an integral structure by means of fixed connection, integral machining or integral molding. The two mounting seats 540 are respectively connected to the linkage mechanism 530. The linkage mechanism 530 can enable the two clamping members 512 to move towards or away from each other synchronously. Thus, the movement of the two clamping members 512 in the second direction can be centered, so that the position of the poultry body in the second direction can be more accurately constrained, and the accuracy of subsequent processing can be improved.

[0105] The linkage mechanism 530 may be a gear rack mechanism, a connecting rod mechanism, or a cam mechanism, etc., as long as it is a mechanism that can realize the synchronous movement of the two clamping members 512 toward or away from each other. Figure 10 The linkage mechanism 530 includes a rotating member, a gear 532 and a rack 533. The gear 532 is connected to the rotating member and can rotate freely relative to the mounting seat 540. The two mounting seats 540 are respectively connected to the racks 533, and the racks 533 are respectively engaged with the opposite sides of the gear 532. According to some embodiments of the present application, the driving mechanism 520 is connected to the mounting seats 540 or the clamping member 512, and an elastic member 534 is connected between the mounting seats 540, and the elastic member 534 provides an elastic force to make the mounting seats 540 move toward each other.

[0106] The driving mechanism 520, the clamping member 512 and the linkage mechanism 530 may be arranged in a variety of ways, for example:

[0107] One of the clamping parts 512 can be driven to move by the driving mechanism 520, that is, the other clamping part 512 can be driven to move toward or away from each other synchronously by the linkage mechanism 530, wherein the driving mechanism 520 can be indirectly connected to one of the clamping parts 512 by being connected to the mounting seat 540 or directly connected to the clamping part 512, and can be indirectly connected to the other clamping part 512 by the linkage mechanism 530;

[0108] Alternatively, the driving mechanism 520 can be used to drive the linkage mechanism 530 to move so as to drive the two clamping members 512 to move toward or away from each other synchronously. In this solution, the driving mechanism 520 is connected to the linkage mechanism 530 through transmission, and is thus indirectly connected to the clamping member 512 through the linkage mechanism 530. For example, taking the solution in which the linkage mechanism 530 adopts a gear rack mechanism as an example, the driving mechanism 520 is connected to the gear 532 to drive the gear 532 to rotate, thereby driving the two racks 533 to move synchronously, thereby driving the mounting seat 540 and the clamping member 512 to move toward or away from each other synchronously.

[0109] refer to Figure 10, in some embodiments, the femur restraint mechanism 500 further includes a guide member 550. The guide member 550 extends along the moving direction of the clamping member 512. The clamping member 512 or the mounting seat 540 is slidably connected to the guide member 550. The clamping member 512 can move along the extending direction of the guide member 550. The guide member 550 is used to limit the moving track of the clamping member 512 to prevent the clamping member 512 from moving offset and affecting the restraint effect and accuracy. The guide member 550 can adopt the structures commonly used in industrial equipment to achieve linear guidance, such as guide rails, slide rails, linear bearings or magnetic levitation guide rails, etc. Thus, when the clamping member 512 is driven to move by any of the above driving and linkage methods, the guide member 550 can ensure that the clamping member 512 moves along the set path and avoid offset, thereby ensuring the effectiveness and accuracy of the femur restraint.

[0110] Reference Figures 11 to 18 , in some embodiments, the poultry restraint device further includes a head restraint mechanism 100. The head restraint mechanism 100 is disposed on one side of the body restraint device along the first direction and is used to restrain the head of the poultry at least along the first direction away from the poultry body.

[0111] Reference Figure 14 and Figure 15 , the head restraint mechanism 100 includes a head support assembly 101. The head support assembly 101 supports the head of the poultry. The head support assembly 101 is provided with a trough 102 for supporting the head of the poultry. One side of the trough 102 has a notch 103 for at least one of the head and neck of the poultry to pass through and enter the trough 102. Specifically, the notch 103 can be an entrance with a closed edge contour, that is, the entrance contour shape of the notch 103 is a closed figure, such as a circle, an ellipse, a triangle or other regular and irregular figures. The entrance contour shape can also be a shape in three-dimensional space; the notch 103 can also be an open entrance without an edge contour, that is, the notch 103 is an open shape without a specific entrance shape, such as a channel formed between two points.

[0112] Reference Figure 14 and Figure 15 , in some embodiments, the trough 102 includes a receiving portion 104. The receiving portion 104 communicates with the notch 103. The head of the poultry enters the receiving portion 104 through the notch 103 and is received and supported in the receiving portion 104. Among them, the receiving portion 104 can be a frame structure or a hollow hemisphere structure. When it is a frame structure, the head of the poultry is in a state of hanging in the receiving portion 104, that is, only the necessary supporting parts of the head of the poultry need to be supported; when it is a hollow hemisphere structure, the head of the poultry is in a state of being completely covered or partially covered and supported in the receiving portion 104; in the above two structures, the receiving portion 104 should at least have a supporting wall for supporting the cheek, mandible or neck of the head of the poultry.

[0113] Reference Figure 14 and Figure 15 In some embodiments, the bracket 102 further includes a guiding portion 105. A notch 103 is provided on one side of the guiding portion 105, and the other side communicates with the accommodating portion 104. The guiding portion 105 has a supporting and guiding function, which can enable the head or neck of the poultry to have a buffer path before entering the accommodating portion 104 to adjust the posture of the head or neck of the poultry. The width of the guiding portion 105 is greater than the width of the head or neck of the poultry, which can enable the neck to have a direction correction stroke before entering the accommodating portion 104 for convenient entry. It can be understood that the width of the guiding portion 105 can be less than or equal to the width of the accommodating portion 104. For example, when it is less, a narrower outlet can be obtained, and a better restraint effect can be achieved to prevent the head or neck of the poultry from falling off therefrom. When it is equal, it can be predicted in advance whether the width of the accommodating portion 104 can meet the requirement for the accommodating width of the head or neck of the poultry, and prevent larger-sized poultry from being stuck in the accommodating portion 104; preferably, the width of the guiding portion 105 is greater than the accommodating width of the accommodating portion 104.

[0114] Reference Figure 14 and Figure 15 In some embodiments, the guiding portion 105 has a first guiding wall 1051 and a second guiding wall 1052 oppositely arranged with respect to the first guiding wall 1051. The head of the poultry enters the accommodating portion 104 from the first guiding wall 1051 and the second guiding wall 1052. During restraint, the first guiding wall 1051 and the second guiding wall 1052 can be symmetrically attached to the opposite side walls of the cheeks, mandible, and neck of the poultry head. When supporting the cheeks, mandible, and neck on both sides of the head, since both sides of the poultry head are restricted, a relatively balanced and symmetrical supporting force can be provided. At the same time, continuous correction is carried out on both sides during the guiding process to straighten the poultry head. The first guiding wall 1051 and the second guiding wall 1052 can also be the two bottom walls corresponding to the top of the poultry head and the mandible. This setting can provide a larger contact surface, and the head of the poultry is restricted by the top of the head and the mandible at the same time. Therefore, the guiding and supporting effect is better; further, the surfaces of the first guiding wall 1051 and the second guiding wall 1052 can be flat or curved. The head of the poultry is clamped into the accommodating portion 104 from the first guiding wall 1051 and the second guiding wall 1052. The simple structure of the first guiding wall 1051 and the second guiding wall 1052 has a good supporting and guiding function to help the head or neck of the poultry smoothly enter the accommodating portion 104. Among them, the distance between the first guiding wall 1051 and the second guiding wall 1052 is the width of the guiding portion 105.

[0115] Reference Figure 14 and Figure 15In some embodiments, the distance between the first guide wall 1051 and the second guide wall 1052 gradually decreases or remains unchanged from the slot 103 inward, wherein, when the distance gradually decreases, it is convenient for the head or neck of the poultry to enter in the early stage of the guiding, while in the later stage of the guiding, the activity space of the head or neck of the poultry is suppressed, so that the head or neck of the poultry is in a state of proper clamping and restriction when entering the receiving portion 104 and is well constrained; when the distance remains unchanged, the effect is the same in the early and late stages of the guiding, both of which have a restrictive effect and also have activity space for proper posture adjustment. It can be understood that the distance can also be changed in the form of first decreasing and then remaining unchanged or first remaining unchanged and then decreasing. Regardless of the distance change form, the distance between the first guide wall 1051 and the second guide wall 1052 needs to be gradually reduced or kept unchanged to meet the corresponding restrictive constraint effect.

[0116] Furthermore, the surfaces of the first guide wall 1051 and the second guide wall 1052 can be flat or curved. The flat surface is smoother and can allow the head or neck of the poultry to enter more smoothly, while the curved surface will have a certain squeezing and relaxing effect on the contact position of the head or neck of the poultry.

[0117] refer to Figure 14 and Figure 15 , a receiving groove 106 is also provided on the head support component 101 at a position corresponding to the receiving portion 104, which is used to receive part of the poultry head. When the poultry head is placed in the receiving portion 104, the receiving portion 104 may easily press against the trachea, causing breathing difficulties. The receiving groove 106 has a certain receiving space to receive the mandible or neck of the poultry, so that after the poultry head is placed in the receiving portion 104, the mandible or neck has a certain space to be accommodated to alleviate the problem of poor breathing of the poultry. In order to make the receiving groove 106 better correspond to the receiving part of the poultry head, the receiving groove 106 is set on the side of the head support component 101 away from the poultry body, specifically at the position where the head support component 101 is used to contact the mandible or neck of the poultry head.

[0118] Specifically, the receiving groove 106 includes a first groove 1061 and a second groove 1062. The first groove 1061 is used to provide space for receiving the throat and trachea of the front part facing the head of the poultry. The second groove 1062 is used to receive the two side parts of the poultry head, and provide space for the throat and trachea on the side parts of the poultry head. The two side parts include the lower jaws on both sides or the cheeks on both sides. In some embodiments, the first groove 1061 is located on the side of the receiving part 104 away from the notch 103. After the poultry head enters the receiving part 104 through the notch 103, it is further partially received by the first groove 1061. The second groove 1062 is arranged on the side of the first groove 1061 facing the notch 103. Therefore, the second groove 1062 is arranged on both sides of the first groove 1061 facing the notch 103 to receive the lower jaws or cheeks of the poultry. The adjacent first groove 1061 and second groove 1062 can better provide space for the throat and trachea at the front part and the side part at the same time.

[0119] Reference Figure 15 , in some embodiments, the first groove 1061 and the second groove 1062 are irregular spoon-shaped structures, that is, their openings can be of various regular or irregular shapes, such as oval, triangular, semi-circular, etc. It can be understood that the spoon-shaped structure will have a depth. The receiving space for the throat and trachea at the front part should be larger than that at the side part to better meet the requirements of breathing and support at the same time. Therefore, the depth of the first groove 1061 at the front part is greater than the depth of the second groove 1062 at the side part.

[0120] Reference Figure 15 , in some embodiments, a holding part 1063 is formed at the connection of the first groove 1061 and the second groove 1062. The holding part 1063 is formed by the transition of the first groove 1061 and the second groove 1062. Therefore, it is adjacent to the second grooves 1062 distributed on both sides and is used to restrict the two side positions of the poultry head. When the first groove 1061 and the second groove 1062 respectively provide receiving and support for the throat and trachea at the front part and the side part, a certain amount of movement space restriction is required to clamp and restrict the poultry head at the same time. Specifically, in one embodiment, the depth of the holding part 1063 is greater than the depths of the first groove 1061 and the second groove 1062, and it is the deepest position of the entire receiving groove 106. When the poultry head is placed in the receiving part 104, the lower jaw neck of the poultry head will slide towards the deepest part of the receiving groove 106, that is, the holding part 1063, until it reaches. Thus, the poultry head will automatically correct its angular position in the receiving groove 106 until it is aligned. Therefore, the problem that the trachea of the poultry head is easily stuck on the side and suffocated due to incorrect angle after being placed in the receiving part 104 is solved.

[0121] It can be understood that based on the first groove 1061 and the second groove 1062, other groove structures can be provided. For example, the first groove 1061 or the second groove 1062 can be split into multiple independent grooves. However, the installation positions and functional effects of these independent grooves are the same as or similar to those of the first groove 1061 or the second groove 1062. At this time, the first groove 1061 or the second groove 1062 should be considered as a combination of the corresponding independent grooves, rather than only including a single groove body.

[0122] Furthermore, the receiving groove 106 is configured as a profiling groove so that the groove wall of the profiling groove adapts to the outer surface of a part of the head of a bird. The groove wall of the profiling groove has the outer surface shape of the lower jaw or the neck in the head of the bird. The profiling setting of the receiving groove 106 includes not only the profiling of the outer surface shape but also further takes into account the size of the head of the bird. When the size is appropriate, the groove wall of the profiling groove can fit and support the head of the bird. Therefore, setting the profiling groove wall can not only meet the accommodation space for the lower jaw or the neck but also provide good restraint and support, preventing poor restraint due to an overly large accommodation space or difficulty in breathing due to no accommodation space.

[0123] Reference Figures 16 to 18 , in some embodiments, the head restraint mechanism 100 includes a head support mode and a head detachment mode. In the head support mode, the head restraint mechanism 100 can support and restrain the head of a bird. In the head detachment mode, the head restraint mechanism 100 cannot support and restrain the head of a bird, and the head of the bird will detach from the head restraint mechanism 100. The head detachment mode can facilitate the removal or dropping of the head of the bird from the head restraint mechanism 100, thereby meeting the requirements of the automated process for stretching, restoring, and detaching the head of the bird.

[0124] Furthermore, with reference to Figure 16 , to facilitate the detachment of the head of a bird from the head support assembly 101, in some embodiments, the head support assembly 101 includes at least two support members 1011. The at least two support members 1011 surround and form a support groove 102. Specifically, the head of the bird is jointly restrained by the at least two support members 1011. In some embodiments, the number of the support members 1011 can be two, three, four, or more, preferably two. The at least two support members 1011 can be separably arranged. In one embodiment, the separation between the support members 1011 is the head detachment mode. At this time, because a certain width is separated between the support members 1011, the support groove 102 is opened, and the head of the bird cannot be supported and thus falls off. Similarly, when the support members 1011 approach each other, it is the head support mode. At this time, the support groove 102 is combined to support the head of the bird.

[0125] The head restraint mechanism 100 further includes a driving module 140. The driving module 140 is connected to at least one supporting member 1011 and is configured to drive the supporting member 1011 to move to open or close the bracket 102. It can be understood that the driving module 140 is used to drive the head supporting assembly 101 to switch between the head supporting mode and the head disengaging mode.

[0126] Specifically, the driving module 140 is connected to at least one supporting member 1011 to control the opening and closing of the supporting member 1011. In some embodiments, the number of the supporting members 1011 is two. One of the supporting members 1011 is in a fixed state, and the other is connected to the driving module 140. The driving module 140 will drive the supporting member 1011 connected thereto to move away from the other supporting member 1011 in a fixed state so as to enter the head disengaging mode, or move closer to the other supporting member 1011 in a fixed state so as to enter the head supporting mode. It can be understood that the way of moving away or moving closer is a way to enter the head disengaging mode or the head supporting mode, and it can also be in a non-translational way of opening or closing along the rotation axis.

[0127] It can be understood that in order to meet the functional requirements, in some embodiments, the driving module 140 may simultaneously include multiple driving components. The driving modes of the driving components can be various, including but not limited to electric driving, elastic force driving, and gravity driving. Therefore, the driving component can be one of a cylinder, an electric cylinder, a spring, a motor, a gravity mechanism, and a hydraulic mechanism. The multiple driving components can be respectively responsible for different driving functions, or can jointly be responsible for the same driving function. In one embodiment, the number of the driving components is two, and the two driving components are respectively responsible for providing the power to enter the head disengaging mode and the power to enter the head supporting mode.

[0128] Reference Figure 17, in some embodiments, the head restraint mechanism 100 has a head support mode and a head release mode. The head restraint mechanism 100 includes an air flow control device having air holes 107 facing the direction of the notch 103, for jetting air to push the head of the poultry out of the trough 102, or for sucking air to adsorb the head of the poultry within the trough 102. It can be understood that when the air holes 107 are aligned with the head of the poultry and jet air to push the head of the poultry to move out of the trough 102, the head restraint mechanism 100 is in the head release mode; when the head restraint mechanism 100 needs to be in the head support mode, the air holes 107 can be aligned with the head of the poultry and suck air to strengthen the fixation of the head of the poultry. It is easy to understand that the jetting and sucking functions of the air flow control device can be used alternatively or simultaneously, that is, only enter the head release mode by jetting air and enter the head support mode by adopting other feasible embodiments, only enter the head support mode by sucking air and enter the head release mode by adopting other feasible embodiments, or enter the head release mode by jetting air and enter the head support mode by sucking air.

[0129] It can be understood that the setting of the air holes 107 is beneficial to the head of the poultry disengaging from the notch 103, so its setting position only needs to be aligned with the notch 103. In one embodiment, the air holes 107 are provided on the trough 102, that is, the air holes 107 are opened at the position of the trough 102 facing the head of the poultry. Specifically, they are opened on the surface of the receiving portion 104 facing the head of the poultry.

[0130] In another embodiment, the air flow control device includes a suction cup, which adsorbs on the surface of the head of the poultry or adsorbs the beak of the poultry to restrain the head of the poultry. Specifically, the suction cup is provided with air holes 107, and the suction cup adsorbs the head or beak of the poultry by sucking air through the air holes 107 to extract vacuum.

[0131] In some variant embodiments, the head restraint mechanism 100 includes a pushing block and a third driving module. The pushing block is connected to the third driving module. The pushing block is used to push the head of the poultry. The third driving module drives the pushing block, and the pushing block drives the head of the poultry to move in the trough 102 in the direction of the notch 103 under the drive of the third driving module, so that the head of the poultry disengages from the trough 102. By pushing the head of the poultry by the pushing block to enter the head release mode. Specifically, the head of the poultry is pushed in the trough 102 until it disengages from the notch 103. It can be understood that when the pushing block retracts to its original position, that is, the position where it does not push the head of the poultry, the trough 102 can support the head of the poultry to enter the head support mode.

[0132] Reference Figure 18, the head restraint mechanism 100 includes a stopper 108. The stopper 108 is located outside the bracket 102 and can move relative to the head support assembly 101 to open or restrict the notch 103. The stopper 108 and the head support assembly 101 jointly restrain the head of the poultry. Specifically, when the head of the poultry enters the notch 103, the stopper 108 will restrict the opening size of the notch 103 so that the head restraint mechanism 100 is in the head support mode. When the head restraint mechanism 100 is in the head detachment mode, the stopper 108 opens the notch 103 and does not restrict the opening size of the notch 103, so that the head of the poultry can detach through the notch 103. Among them, the stopper 108 is driven by the fourth drive module to move towards the notch 103. The moving methods include translation and rotation. By means of translation or rotation, the opening size of the notch 103 is finally restricted, and after translation or rotation reaches the position, it abuts against the posterior neck position of the head of the poultry to play a certain role in restraint and fixation.

[0133] In one embodiment, the stopper 108 includes two cuboids or two V-shaped blocks, and the two cuboids or two V-shaped blocks rotate and approach each other to enclose and restrict the notch 103. The edges and edges of the two cuboids or two V-shaped blocks are all transitioned by arcs; in another embodiment, the stopper 108 includes one cuboid or one cylinder, and the cuboid or cylinder moves towards the notch 103 to restrict the notch 103. The edges and edges of the cuboid are transitioned by arcs.

[0134] Based on the above embodiments, the head restraint mechanism 100 can restrain the head and neck of the poultry at least in the first direction. Thus, the relative positions of the head restraint mechanism 100 and the femur restraint mechanism 500 realize the stretching of the neck and the adjustment of the body position. Refer to Figures 11 to 18 , in some embodiments of the poultry restraint device, it further includes a stretching device 130. The stretching device 130 is connected to the femur restraint mechanism 500 and / or the head restraint mechanism 100. The stretching device 130 is configured to drive the femur restraint mechanism 500 and the head restraint mechanism 100 to move relative to each other at least in the first direction, so that the neck of the poultry is stretched at least in the first direction.

[0135] Specifically, the stretching device 130 is connected to at least one of the head restraint mechanism 100 or the femur restraint mechanism 500, which can be directly or indirectly connected. The connection methods include fixed connection and movable connection, enabling the stretching device 130 to drive at least one of the head restraint mechanism 100 or the femur restraint mechanism 500 to move, so that the femur restraint mechanism 500 and the head restraint mechanism 100 move relative to each other at least along the first direction. Specifically, the connection of the stretching device 130 includes various implementation manners. For example, the stretching device 130 is connected to the head restraint mechanism 100. At this time, the femur restraint mechanism 500 is fixed, and the head restraint mechanism 100 is driven by the stretching device 130 to move; or, the stretching device 130 is connected to the femur restraint mechanism 500. At this time, the head restraint mechanism 100 is fixed, and the femur restraint mechanism 500 is driven by the stretching device 130 to move; or, the stretching device 130 is simultaneously connected to the head restraint mechanism 100 and the femur restraint mechanism 500. At this time, the head restraint mechanism 100 and the femur restraint mechanism 500 are simultaneously driven by the stretching device 130 to move relatively.

[0136] In some embodiments, the stretching device 130 can adopt a power mechanism capable of outputting a constant force. For example, a cylinder, a hydraulic cylinder, or a combined mechanism of a motor and a synchronous belt mechanism, a lead screw transmission mechanism, a rack and pinion transmission, or a link mechanism and other conventional linear drive mechanisms can be used. Through reasonable configuration, it can drive the relative movement of the head restraint mechanism 100 and / or the femur restraint mechanism 500, and stretch the neck of the poultry.

[0137] In addition, the stretching device 130 can also adopt a power mechanism capable of outputting a non-constant force, such as a spring mechanism, a nitrogen spring mechanism, a conventional cylinder, an electric cylinder, a power mechanism with a permanent magnet as the power source, or a power mechanism with an electromagnet as the power source, etc., to realize the drive of the head restraint mechanism 100 and / or the femur restraint mechanism 500.

[0138] In some embodiments, the stretching device 130 is a constant force stretching mechanism. The constant force stretching mechanism is connected to the femur restraint mechanism 500 and / or the head restraint mechanism 100, and is used to drive the femur restraint mechanism 500 and the head restraint mechanism 100 to move away from each other at least along the first direction until the neck of the poultry reaches a stretched state. The above-mentioned power mechanism capable of outputting a constant force can be adopted. Among them, the constant force refers to a relatively constant acting force, which can provide a stable acting force for the stretching of the neck, so as to continuously restrain the head and neck of the poultry.

[0139] Hereinafter, the specific connection and movement schemes of the head restraint mechanism 100, the femur restraint mechanism 500, and the stretching device 130 will be described in detail:

[0140] Refer to Figures 11 to 13 wherein, Figure 13The dotted line therein is an auxiliary line, which is used to represent the assembly relationship of the disassembled parts for easy understanding and does not represent other meanings. In some embodiments, the stretching device 130 includes a constant force stretching mechanism, and the constant force stretching mechanism is connected to the head restraint mechanism 100. A power mechanism capable of outputting a constant force can be adopted. For example, a cylinder, a hydraulic cylinder, or a combined mechanism of a motor and a synchronous belt mechanism, a screw drive mechanism, a rack and pinion drive, or a link mechanism and other conventional linear drive mechanisms can be adopted. By reasonable configuration, the head restraint mechanism 100 can be driven to move away from the femur restraint mechanism 500 at least along the first direction, thereby stretching the neck of the poultry. It can be understood that the necks of poultry with different body sizes are of different lengths. Therefore, the use of a constant force stretching mechanism can have the effect of adaptive stretching and can maintain a constant force output on the neck of the poultry.

[0141] As an embodiment, the constant force stretching mechanism can adopt a power mechanism such as a gravity mechanism, a constant force spring mechanism, or a spring cam mechanism to achieve the adaptive stretching of the neck of the poultry. For example, taking the scheme of using a gravity mechanism as the constant force stretching mechanism and this constant force stretching mechanism is used to drive the head restraint mechanism 100 away from the femur restraint mechanism 500 as an example, referring to Figure 11 and Figure 12 , the constant force stretching mechanism includes a mounting frame 131, a guide wheel 132, and a counterweight. The guide wheel 132 is mounted on the mounting frame 131. The counterweight is connected to the head restraint mechanism 100 through a driving rope 133, and the driving rope 133 is wound around the guide wheel 132. The guide wheel 132 is used to carry the counterweight connected by the driving rope 133 and to limit and guide the position of the driving rope 133. Therefore, the number and position of the guide wheel 132 can be reasonably configured according to the installation needs. Along the position of the guide wheel 132 on the proximal end of the driving rope 133 of the head restraint mechanism 100, it is at least farther away from the femur body restraint device in the first direction than the head restraint mechanism 100, so as to ensure that the counterweight can drive the head restraint mechanism 100 to stretch at least along the first direction through the driving rope 133. Using a gravity mechanism as the constant force stretching mechanism has the characteristics of simple structure and easy implementation, and the counterweight can be replaced according to the required acting force, thereby improving the applicability. In other embodiments, the method of driving the femur restraint mechanism 500 to move relative to the head restraint mechanism 100 through the constant force stretching mechanism, or the method of driving the femur restraint mechanism 500 and the head restraint mechanism 100 to move relative to each other respectively through the constant force stretching mechanism is the same as the above.

[0142] In some embodiments, the stretching device 130 is also used to drive the femur restraint mechanism 500 and / or the head restraint mechanism 100 to move towards each other at least along the first direction to a set distance to relax the neck of the poultry. This set distance can be reasonably configured according to the body size of the restrained poultry, so as to be applicable to poultry of various body sizes and improve the applicability of the poultry restraint device.

[0143] Among them, in the solution where the gravity mechanism is used as the constant-force stretching mechanism, the stretching device 130 may further include a retracting mechanism, which is connected to the femur restraint mechanism 500 and / or the head restraint mechanism 100, and is used to drive the femur restraint mechanism 500 and / or the head restraint mechanism 100 to move towards each other against the acting force of the gravity mechanism to a set distance, so as to relax the neck of the poultry.

[0144] Based on the above embodiments, with the cooperation of the femur restraint mechanism 500, the head restraint mechanism 100 and the stretching device 130, the neck can be stretched. At the same time, the body can abut the femur against the first restraint member 510 of the femur restraint mechanism 500, and can keep the poultry body abutting against the first restraint member 510 of the femur restraint mechanism 500, realizing the accurate positioning of the femur position, thereby improving the accuracy of poultry body restraint.

[0145] In some other embodiments, the femur can also be abutted against the first restraint member 510 of the femur restraint mechanism 500 by pushing the body at least along the first direction. Thus, the position of the femur can be effectively restricted. For example, in some embodiments, the poultry restraint device further includes a pushing device (not shown). The pushing device is arranged on the side of the femur restraint mechanism 500 away from the head, and is used to push the body of the poultry at least along the first direction. It can directly push the body or push the body by pushing other parts. For example, the femur, the arm bone, the tail of the body or other parts of the body can be pushed at least along the first direction, so that the body of the poultry is pushed towards the head direction, so that the femur can be abutted against the femur restraint mechanism 500.

[0146] Specifically, the pushing device may include a stopper and a pushing mechanism (not shown). Among them, the stopper is located on the side of the femur restraint mechanism 500 away from the head, and the pushing mechanism is connected to the stopper and is used to push at least towards the femur restraint mechanism 500 in the first direction. Thus, the stopper can push the body forward from the tail of the body at least along the first direction. Similarly to the stretching device 130, the pushing mechanism can adopt a constant-force power mechanism that can output a constant force, or a power mechanism that can output a non-constant force. For the pushing mechanism of some embodiments, a stopper reset mechanism can also be provided to drive the stopper to reset. In addition, the pushing device can also be provided with a stopper guide member, and the stopper guide member guides the movement of the stopper along the first direction to avoid the deviation of the stopper movement. The pushing device can also adopt the method of blowing air towards the tail of the body along the first direction to blow the body forward, so that the femur is abutted against the femur restraint mechanism 500.

[0147] It should be noted that when restraining poultry, to achieve the purpose of pushing the body at least along the first direction so that the femur abuts against the first restraint member 510 of the femur restraint mechanism 500, the method of stretching the neck at least along the first direction by cooperating the above-mentioned head restraint mechanism 100 and the stretching device 130 can be adopted, or the method of pushing the body of the poultry at least along the first direction by the pushing device can be adopted, or both methods can be adopted simultaneously. Of course, according to the previous embodiments, in the femur restraint structure of some embodiments, a second restraint member is further provided. The second restraint member is arranged adjacent to the first restraint member 510 along the first direction and has a set interval, so as to form a card slot between the first restraint member 510 and the second restraint member. The slot openings of the card slot face each other, and can clamp the femur, so as to limit the position of the femur at least on both sides in the first direction. In this solution, it is possible to restrain the position of the femur without pushing or pulling the body along the first direction, so there is no need to configure the above-mentioned stretching device 130 or pushing device. Of course, in this solution, configuring the above-mentioned stretching device 130 or pushing device can also assist in improving the femur restraint effect. In addition, for the purpose of stretching and restraining the neck of the poultry, the above-mentioned stretching device 130 can also be configured. In specific implementation, various embodiments provided by the present application can be reasonably selected according to actual restraint requirements.

[0148] As can be seen from the above embodiments, the body restraint device can effectively restrain the position of the femur at least in the first direction, so that the body of the poultry can have a definite position in the first direction. On this basis, the body of the poultry can be restrained at a set position in the third direction by restraining the back, chest, and abdomen of the poultry at least in the third direction. For example, a back restraint structure for restraining the back, a chest support mechanism for restraining the chest, an abdomen support mechanism for restraining the abdomen, etc. are provided. The following are some embodiments:

[0149] Refer to Figure 12 and Figure 13 , in some embodiments, the body restraint device further includes a back restraint mechanism 300. The back restraint mechanism 300 is arranged adjacent to the femur restraint mechanism 500 and is used to restrain the back of the body of the poultry at least in the third direction.

[0150] Refer to Figures 19 to 21, in some embodiments, the back restraint mechanism 300 includes an adsorption component. The adsorption component includes an adsorbent 310. An adsorption port is provided on one side of the adsorbent 310. The adsorbent 310 can be connected to a gas source to form a negative pressure at the adsorption port for adsorbing the back of the poultry. The outer side surface of one side of the adsorption port has an adsorption surface. The adsorption port penetrates through the adsorption surface. The adsorbent 310 is provided with a plurality of adsorption ports, and the adsorption ports can be evenly arranged on the adsorption surface. The back of the poultry is adsorbed and fixed by the adsorbent 310, so that the back of the poultry can be better fixed. The adsorption force generated by the adsorbent 310 will not generate a large pressing force on the back of the poultry, so that the back of the poultry will not be damaged.

[0151] The adsorption port of the adsorbent 310 can be straight plate-shaped, shaped, wavy, arc-shaped, etc., so that the adsorption surface of the adsorption port is a flat structure or a curved surface structure, or a shaped structure adapted to the back of the poultry. When the adsorption surface is a flat structure, the processing technology of the adsorbent 310 is less difficult. When the adsorption surface is a curved surface structure or a shaped structure adapted to the back of the poultry, it can better fit the back of the poultry, so as to enhance the adsorption effect. For example, the back plate can be straight plate-shaped, and the adsorption port can be directly opened on the back plate to form the above-mentioned adsorbent 310.

[0152] Reference Figures 20 to 24, in some embodiments, one side of the adsorbing member 310 includes a first region and a second region. The first region is provided with a first adsorption port 311, and the second region is provided with a second adsorption port 312. The adsorbing member 310 can be connected to a gas source to form a negative pressure at the first adsorption port 311 and the second adsorption port 312. The first region is used to adsorb a first position on the back of the poultry, and the second region is used to adsorb a second position on the back of the poultry. Wherein, the first position on the back is the position on the back of the poultry corresponding to the thoracic vertebra and / or ilium, and the second position on the back is the position on the back of the poultry corresponding to the caudal vertebra. Thus, the adsorption effects of the adsorbing member corresponding to the first position and the second position can effectively restrain the back of the poultry, and respectively restrain the position of the thoracic vertebra and / or ilium, and restrain the position of the caudal vertebra, which is convenient for the operation of inserting a detection object into the poultry body for related processing. For example, in the processing operation of sex identification by inserting a detection object into the poultry body from the cloaca, it can be known from the distribution of the bones and internal organs of the poultry that the thoracic vertebra and / or ilium of the poultry are located above and on both sides of the ovary or testis, and the caudal vertebra corresponds to the cloaca position. Therefore, when the adsorbing member 310 restrains the first position on the back of the poultry, it can effectively restrain the thoracic vertebra and / or ilium, avoiding abnormal movement of the thoracic vertebra and / or ilium, so that the ovary or testis will not have abnormal movement. When the adsorbing member 310 restrains the second position on the back of the poultry, it can effectively restrain the caudal vertebra, avoiding abnormal movement of the caudal vertebra, so that the cloaca position will not have abnormal movement, which is beneficial for the detection object to be inserted into the poultry body from the cloaca for sex detection, and further beneficial for the sex identification of the poultry.

[0153] In this application, the adsorption assembly is used to adsorb and fix the back of the poultry, so that the back of the poultry can be better fixed. The adsorption force generated by the adsorption assembly will not generate a large pressing force on the back of the poultry, so it will not cause harm to the back of the poultry. Moreover, it can adsorb different positions on the back of the poultry respectively, so as to more firmly fix the back of the poultry and improve the fixing effect when the back of the poultry is fixed. When breeding poultry, it is beneficial for sex identification, feeding, and vaccination of poultry, thereby improving the breeding efficiency of poultry.

[0154] Further, adsorption ports are directly provided in the first region and the second region of the adsorbing member 310, or suction cups are provided in the first region and the second region.

[0155] Among them, the first region is provided with a plurality of first adsorption ports 311, and there is a second partition 313 between adjacent first adsorption ports 311. The second region is provided with a plurality of second adsorption ports 312, and the plurality of second adsorption ports 312 are arranged at intervals along the extending direction of the caudal vertebra of the poultry. There is a first partition 314 between adjacent second adsorption ports 312, and the first partition 314 is inclined towards the tail direction of the caudal vertebra of the poultry.

[0156] The first region is provided with a first suction cup, and the adsorption end of the first suction cup is provided with a first adsorption port 311. The second region is provided with a second suction cup, and the adsorption end of the second suction cup is provided with a second adsorption port 312.

[0157] The above adsorption assembly further includes a base 320. The adsorbent 310 is detachably connected to the base 320. The base 320 is connected to the adsorbent 310. The interiors of the adsorbent 310 and the base 320 are hollow and communicate with each other to form an inner cavity. The adsorption port is arranged on one side of the adsorbent 310 and communicates with the inner cavity. A connection port 327 communicating with the inner cavity is arranged on the base 320, and the connection port 327 is used to access the air source. The base 320 is provided with a mounting groove, and the adsorbents 310 are all mounted in the mounting groove, and the mounting groove is used to mount the adsorbents 310. The interior of the adsorbent 310 is hollow to form an inner cavity, and the adsorption port communicates with the inner cavity. When the air source is accessed, the air source forms a negative pressure at the adsorption port through the inner cavity, thereby adsorbing and fixing the back of the poultry. The back restraint mechanism 300 further includes an air source device, and the air source device is communicated with the connection port 327 through a trachea. Thus, when the air source is accessed, the air source forms a negative pressure at the adsorption port through the connection port 327, and a negative pressure with a value of 0.1 Mpa to 0.2 Mpa is generated at the adsorption port. Among them, the adsorbent 310 and the base 320 can be an integral structure or a split structure. Among them, the adsorbent 310 can be a suction cup, and the suction cup can be mounted on the base 320 by an embedding method.

[0158] The adsorbent 310 is slidably mounted on the base 320 or can be directly snap-mounted on the base 320. Of course, the base 320 and the adsorbent 310 can be an integral structure, and the base 320 and the adsorbent 310 can be a split structure.

[0159] Referring to Figure 21 and Figure 22 , the base 320 can be a connecting cover 326. The connecting cover 326 is connected to the adsorbent 310. The interiors of the adsorbent 310 and the connecting cover 326 are hollow and communicate with each other to form an inner cavity. The adsorption port is arranged on one side of the adsorbent 310 and communicates with the inner cavity. A connection port 327 communicating with the inner cavity is arranged on the connecting cover 326, and the connection port 327 is used to access the air source.

[0160] In one embodiment, the adsorbent 310 has a body, and an opening can be directly made on the body, so as to form an adsorption port on the body. An inner cavity communicating with the adsorption port is formed inside the body. A connection port 327 is arranged on the body, and the connection port 327 communicates with the inner cavity. Therefore, when the air source is accessed, the air source forms a negative pressure at the adsorption port through the connection port 327, thereby adsorbing and fixing the back of the poultry.

[0161] In one embodiment, the back restraint mechanism 300 can be provided with different regions to adsorb and restrain different positions of the back of the poultry. The following refers to Figures 21 to 23Describe a specific embodiment of the back restraint mechanism 300 that sets different regions to adsorb and restrain different positions of the back of poultry.

[0162] The adsorbing member 310 can be one, and both a first region and a second region are provided on the adsorbing member 310. The first region and the second region are respectively provided with a first adsorption port 311 and a second adsorption port 312. The air source forms negative pressure at the first adsorption port 311 and the second adsorption port 312, so as to respectively restrain the first position and the second position of the back of the poultry. In order to be able to replace the adsorbing member 310 that adsorbs different positions on the back of the poultry, the adsorbing member 310 can be two. The adsorbing member 310 includes a first adsorbing member 315 and a second adsorbing member 316. The adsorption assembly further includes a base 320. One side of the first adsorbing member 315 is provided with a first region, and one side of the second adsorbing member 316 is provided with a second region. The first adsorbing member 315 and the second adsorbing member 316 are detachably connected to the base 320, so that when fixing poultry of different sizes or different species, the first adsorbing member 315 and / or the second adsorbing member 316 can be replaced according to actual needs.

[0163] A through hole is provided at the top of the base 320. The through hole is communicated with the first adsorption port 311 and the second adsorption port 312. When the air source is connected, the air source forms negative pressure at the first adsorption port 311 and the second adsorption port 312 through the through hole. The through hole can be two, namely a first through hole 323 and a second through hole 324. When the air source is connected, the air source respectively forms negative pressure at the first adsorption port 311 and the second adsorption port 312 through the first through hole 323 and the second through hole 324. Two side surfaces of the base 320 are provided with avoidance spaces 325. When fixing the poultry, sometimes it is necessary to fix the position of the femur of the poultry. Therefore, the avoidance spaces 325 can avoid a block (not shown in the figure) that restrains the femur of the poultry.

[0164] In addition, the back restraint mechanism 300 further includes an air source device. The air source device is communicated with the through hole of the base 320 through a trachea, and generates a negative pressure with a negative pressure value of 0.1 Mpa to 0.2 Mpa at the adsorption port. The air source devices for the first adsorbing member 315 and the second adsorbing member 316 to access the air source can be set separately. For example, the size of the air source accessed by the first adsorbing member 315 is larger than the size of the air source accessed by the second adsorbing member 316, so as to form different negative pressures at the first adsorption port 311 and the second adsorption port 312. Moreover, when the first adsorbing member 315 accesses the air source, the second adsorbing member 316 can not access the air source, or when the second adsorbing member 316 accesses the air source, the first adsorbing member 315 does not access the air source. Thus, the access situation of the air source can be adjusted according to actual needs, and it is more suitable for fixing the backs of different poultry.

[0165] Reference Figure 20 and Figure 21, the base 320 is provided with mounting grooves, and the first suction member 315 and the second suction member 316 are both mounted in the mounting grooves. Of course, there can be two mounting grooves, namely the first mounting groove 321 and the second mounting groove 322. The first mounting groove 321 is used to mount the first suction member 315, and the second mounting groove 322 is used to mount the second suction member 316. The first suction member 315 is evenly arranged with suction ports corresponding to the first area of the suction surface for sucking the first position on the back of the poultry. The second suction member 316 is also evenly arranged with suction ports corresponding to the second area of the suction surface for sucking the second position of the poultry. The first mounting groove 321 and the second mounting groove 322 are opened at the bottom of the base 320. The first mounting groove 321 and the second mounting groove 322 are arranged adjacent to each other, and the first mounting groove 321 and the second mounting groove 322 can be separated by a spacer in the middle. The first suction member 315 is hollow inside to form a first inner cavity, and the first suction port 311 communicates with the first inner cavity. The second suction member 316 is hollow inside to form a second inner cavity, and the second suction port 312 communicates with the second inner cavity. When the air source is connected, the air source forms negative pressure at the first suction port 311 and the second suction port 312 through the first inner cavity and the second inner cavity, so as to form negative pressure at the first position and the second position on the back of the poultry, and then adsorb and fix the back of the poultry.

[0166] Reference Figure 20 and Figure 21 , the first suction member 315 and the second suction member 316 can be slidably mounted on the base 320, or can be directly snap-fitted on the base 320. Of course, the base 320, the first suction member 315 and the second suction member 316 can be of an integral structure, and the first suction member 315 and the second suction member 316 can also be fixedly mounted on the base 320.

[0167] Among them, with reference to Figures 20 to 23 , the bottom surface of the base 320 can be provided with the first mounting groove 321 and the second mounting groove 322. The top surface of the connecting cover 326 is provided with a connection port 327 for connecting the air source. The connection port 327 communicates with the first suction member 315 and the second suction member 316. Thus, when the air source is connected, the air source forms negative pressure at the first suction port 311 and the second suction port 312 through the first through hole 323 and the second through hole 324 respectively. In some other embodiments, the back restraint can also be achieved by abutting. For example, the back restraint mechanism 300 includes a back plate, and a abutting surface is provided on one side of the back plate facing the femur restraint mechanism 500. The abutting surface is used to abut and restrain the back of the poultry at least in the third direction to achieve the back restraint.

[0168] Reference Figure 12 , Figure 13 and Figure 24, in some embodiments, the body restraint device further includes a moving mechanism 700, which is connected to the back restraint mechanism 300 and is configured to move the back restraint mechanism 300 closer to or farther from the femur restraint mechanism 500.

[0169] The moving mechanism 700 may be a driving component that directly drives the back restraint mechanism 300 to move. Alternatively, the moving mechanism 700 includes a driving component and a moving component, and the driving component drives the moving component to move, thereby driving the back restraint mechanism 300 to move. The movement mode may be linear movement, curvilinear movement, or rotational movement. The movement mode of the moving mechanism 700 is not limited in this embodiment. The moving mechanism 700 is mainly used to move the back restraint mechanism 300 closer to or farther from the support mechanism 200 in order to restrain the back of the poultry.

[0170] Reference Figure 12 and Figure 13 , in some embodiments, the body restraint device further includes a support mechanism 200, which is configured to restrain the abdomen and / or chest of the poultry and can be used in cooperation with the back restraint mechanism 300 to achieve the restraint and limit of the body in the third direction. The support mechanism 200 may include a chest support mechanism 202 and an abdomen support mechanism 201, which are respectively used to carry the chest and abdomen of the poultry.

[0171] Reference Figures 25 to 29 , in some embodiments, the body restraint device further includes a lifting mechanism 600, which is configured to drive the support mechanism 200 to lift at least the chest and / or abdomen of the poultry in the third direction, thereby enabling the body to be lifted toward the back restraint mechanism 300 for the convenience of back restraint. Specifically, the chest and / or abdomen of the poultry is lifted by the lifting mechanism 600, the chest support mechanism 202, and / or the abdomen support mechanism 201 so that the back of the poultry abuts against the back restraint mechanism 300 to achieve back restraint and effective restraint of the body in the third direction. The back restraint mechanism 300 can take various forms as long as it can restrain the back of the poultry body in the third direction. For example, in the previous embodiments, the back restraint mechanism 300 may include a back plate. After the lifting of the lifting mechanism 600, the back of the body abuts against the back plate to achieve the restraint of the body in the third direction. Or, the back restraint mechanism 300 is configured with a back plate that can be lifted and lowered, and the back plate is moved closer to or farther from the support mechanism 200 by lifting and lowering, so as to abut against and restrain the back of the poultry on the support mechanism 200. The back restraint mechanism 300 can also use other methods in the above embodiments to achieve the restraint of the back of the poultry, such as adsorbing the back of the poultry to the adsorbent to achieve back restraint. In addition, the lifting of the chest and / or abdomen can also make the body and ankles of the poultry relatively far away from each other to stretch the legs, thereby adjusting the posture of the poultry. The following provides some specific implementation manners:

[0172] In some embodiments, the lifting mechanism 600 may adopt a power mechanism capable of outputting a constant force. For example, the lifting mechanism 600 may adopt a cylinder, a hydraulic cylinder, or a combined mechanism of a motor and a synchronous belt mechanism, a lead screw transmission mechanism, a rack and pinion transmission, or a link mechanism, etc., which are conventional linear drive mechanisms. Through reasonable configuration, it can drive the support mechanism 200 to perform a lifting motion at least along the third direction and drive the support mechanism 200 to reset.

[0173] In addition, the lifting mechanism 600 may also adopt a power mechanism capable of outputting a non-constant force, such as a spring mechanism, a nitrogen spring mechanism, a conventional cylinder, an electric cylinder, a power mechanism with a permanent magnet as the power source, or a power mechanism with an electromagnet as the power source, etc.

[0174] In the poultry restraint device of some embodiments, the lifting mechanism 600 may also drive the support mechanism 200 to move along the third direction through a lifting component to approach or contact the chest and / or abdomen of the poultry, or appropriately lift the chest and / or abdomen of the poultry, and further drive the support mechanism 200 to adaptively lift the chest and / or abdomen of the poultry and maintain the lifted state through a constant force component, so as to realize the adaptive adjustment of the posture of the poultry. For example, referring to Figures 25 to 29 , the lifting mechanism 600 includes a lifting component and a constant force component. The constant force component is used to provide a force to keep the support mechanism 200 in contact with the chest and / or abdomen of the poultry. Specifically, in this embodiment, in the lifting mechanism 600, the lifting component is used to drive the support mechanism 200 to move along the third direction to an initial position. The constant force component is connected to the support mechanism 200, and the constant force component provides a force to drive the support mechanism 200 to lift upward along the third direction from the initial position. Thus, the support mechanism 200 can be first driven to the initial position by the lifting component. At this time, the support mechanism 200 may be in a state of slightly contacting the chest and / or abdomen of the body or having a certain gap from the chest and / or abdomen of the body, and then the constant force component provides a force to drive the support mechanism 200 to lift along the third direction from the initial position, so as to prevent the support mechanism 200 from hitting the abdomen and / or chest and causing harm to the poultry. In this embodiment, the lifting component can also drive the support mechanism 200 to reset to the initial position against the force of the constant force component, thereby releasing the lifting of the chest and / or abdomen.

[0175] It can be understood that poultry of different species and ages have different body sizes (at least the size of the body), and even for poultry of the same species and age, there are individual differences in body size. Therefore, when the chest and / or abdomen of the body are constrained by the support mechanism 200, the specific positions of the chest and / or abdomen of poultry of different body sizes are different. In the poultry restraint device of this embodiment, the lifting mechanism 600 is provided with a constant force component. Under the action of the constant force component, the support mechanism 200 lifts the chest and / or abdomen of the body, which has an adaptive effect, can adapt to poultry of different body sizes, and can expand the applicable range of the poultry restraint device. The lifting component can also be used to drive the support mechanism 200 to reset in the reverse direction of the third direction to the initial position to release the lifting of the abdomen. Among them, the initial position can be reasonably configured according to the body size of the poultry to be processed, and the specific value of the acting force of the constant force component can be reasonably configured according to the body size of the poultry to be processed and the degree of lifting required.

[0176] Among them, the above-mentioned constant force component can adopt power mechanisms such as a gravity mechanism, a constant force spring mechanism or a spring cam mechanism, etc. to realize the adaptive lifting of the support mechanism 200. For example, referring to Figures 25 to 29 , the constant force component includes a bracket 605 and a counterweight. A fixed pulley 606 is provided on the bracket 605. The counterweight is connected to the support mechanism 200 through a driving rope (not shown), and the driving rope is wound around the fixed pulley 606. The fixed pulley 606 is used to carry the counterweight connected by the driving rope and to limit and guide the position of the driving rope. Therefore, the number and position of the fixed pulley 606 can be reasonably configured according to the installation needs. The position of the fixed pulley 606 along the driving rope at the proximal end of the support mechanism 200 is at least higher than the connection position of the driving rope and the support mechanism 200 in the lifting direction (the third direction) to ensure that the counterweight can drive the support mechanism 200 to perform a lifting movement along the third direction through the driving rope. Using a gravity mechanism as the constant force component has the characteristics of simple structure and easy implementation, and the acting force of the constant force component can be changed by replacing the counterweight, thereby improving the applicability of the support mechanism 200.

[0177] Referring to Figures 25 to 29 , the support mechanism 200 includes an abdominal support mechanism 201 for carrying the abdomen of the poultry. The abdominal support mechanism 201 is connected to the lifting mechanism 600. The lifting mechanism 600 is used to drive the abdominal support mechanism 201 to move at least in the third direction to lift the abdomen of the poultry. The lifting direction of the abdominal support mechanism 201 can be the third direction, or a direction with a set deviation angle relative to the third direction is also possible.

[0178] In the above embodiments, the stroke of the lifting mechanism 600 for driving the abdominal support mechanism 201 to move can be reasonably configured according to the actual required posture. For example, it can be lifted to just abut against the abdomen of the poultry to achieve positioning and restraint and avoid abdominal shaking. It can also be further lifted to a set position to lift the buttocks of the poultry. This posture is particularly suitable for processing the set position of the buttocks of the poultry. For example, this posture can keep the cloaca of the poultry in the corresponding position and avoid large-amplitude shaking of the cloaca, and is suitable for processing operations such as identifying and cleaning the cloaca, or for processing operations such as injecting, detecting, and identifying by inserting an instrument into the cloaca.

[0179] Reference Figures 25 to 29 , in the above embodiments, the support mechanism 200 may further include a chest support mechanism 202 for carrying the chest of the poultry, and the lifting mechanism 600 is used to drive the abdominal support mechanism 201 to move relative to the chest support mechanism 202 to achieve abdominal lifting. The lifting mechanism 600 may include a first lifting component 601 and a first constant force component 603. The first lifting component 601 and the first constant force component 603 may respectively adopt any one of the lifting components and constant force components described above. The first lifting component 601 and the first constant force mechanism are respectively connected to the abdominal support mechanism 201. The first lifting component 601 is used to drive the abdominal support mechanism 201 to move to the initial position, and the first constant force component 603 provides a force to the abdominal support mechanism 201 to drive the abdominal support mechanism 201 to lift the abdomen of the poultry at least along the third direction. When the abdominal support mechanism 201 is in the initial position, there is at least a set initial distance between the abdominal support mechanism 201 and the chest support mechanism 202 along the third direction. Within this initial distance range, there is a small gap between the abdominal support mechanism 201 and the abdomen of the poultry in the third direction, or the abdominal support mechanism 201 slightly contacts the abdomen of the poultry. Thus, it is possible to avoid the abdominal support mechanism 201 accidentally injuring the abdomen of the poultry and reduce the lifting stroke. For example, in the solution of driving the abdominal support mechanism 201 to lift from the initial position by the constant force mechanism, if the distance between the abdominal support mechanism 201 and the abdomen of the poultry is large, a relatively long empty stroke is required during the lifting process. In the solution of using the above gravity mechanism as the constant force component to drive the abdominal support mechanism 201 to lift, the relatively long empty stroke will also cause an increase in the acceleration of the gravity mechanism, thereby hitting the abdomen of the poultry and causing harm.

[0180] In some embodiments, the above-mentioned initial distance is 10 mm to 15 mm. For example, it can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, or other values between 10 mm and 15 mm. Configuring the initial distance to be 10 mm to 15 mm is applicable to the abdomens of most normal chicks. The abdominal support mechanism 201 and the chest support mechanism 202 are configured in terms of structure and movement with this size as a reference, which can better apply to the chest and abdominal restraint of chicks. According to different body sizes of poultry, it can also be increased or decreased based on the above-mentioned initial distance to adapt to the restraint and body adjustment of poultry with different body sizes, which will not be elaborated here.

[0181] Reference Figures 25 to 29 , in some embodiments, the support mechanism 200 includes a chest support mechanism 202 for carrying the chest of the poultry, and a lifting mechanism 600 is connected to the chest support mechanism 202 for driving the chest support mechanism 202 to lift at least in the third direction. The lifting direction of the chest support mechanism 202 can be the third direction, or a direction with a set deflection angle relative to the third direction is also acceptable. Thus, when restraining the poultry, the poultry can be placed in the posture adjustment device of the embodiment of the present application in any posture with the head facing the first direction. By the support mechanism 200 restraining and lifting the chest of the poultry body at least in the third direction, the restraint of the body is achieved.

[0182] In the above embodiment, the stroke of the lifting mechanism 600 driving the chest support mechanism 202 to move can be reasonably configured according to the actually required posture. For example, it can be lifted to just abut against the chest of the poultry to achieve positioning restraint and avoid chest shaking. It can also be further lifted to a set position to lift the poultry body so that the back abuts against the back restraint mechanism 300, thereby restraining the back position of the body, which helps subsequent processing operations and improves the accuracy of operations.

[0183] In some embodiments, the support mechanism 200 may include a chest support mechanism 202 and an abdominal support mechanism 201 for carrying the chest and abdomen of the poultry respectively. The lifting mechanism 600 includes two groups, which are respectively used to drive the chest support mechanism 202 and the abdominal support mechanism 201 to lift. For the convenience of description, the two groups of lifting mechanisms 600 are respectively denoted as the first lifting mechanism and the second lifting mechanism. Among them, the first lifting mechanism is connected to the abdominal support mechanism 201 for driving the abdominal support mechanism 201 to lift the abdomen of the poultry at least in the third direction, and the second lifting mechanism is connected to the chest support mechanism 202 for driving the chest support mechanism 202 to lift the chest of the poultry at least in the third direction.

[0184] Among them, the first lifting mechanism may include a first lifting component 601 and a first constant force component 603, which can be independent of each other or can be configured with a set of cooperative logics through a programmable logic controller according to actual requirements. The second lifting mechanism may include a second lifting component 602 and a second constant force component 604. Among them, the first lifting component 601 and the second lifting component 602 can respectively adopt any one of the lifting components proposed in the previous embodiments, and the first constant force component 603 and the second constant force component 604 can adopt any one of the constant force components proposed in the previous embodiments. The first lifting component 601 and the first constant force component 603 are respectively connected to the abdominal support mechanism 201, and the second lifting component 602 and the second constant force component 604 are respectively connected to the chest support mechanism 202.

[0185] Reference Figure 29 , in some embodiments, the chest support mechanism 202 includes a support member 210. The support member 210 can be a block-shaped or plate-shaped structure. When restraining a poultry, the poultry is placed on the support member 210, and the support member 210 can bear the chest of the poultry. The support member 210 can also be provided with a receiving groove 211, and the receiving groove 211 can at least accommodate a part of the chest of the poultry. When fixing the poultry, a part of the chest of the poultry is accommodated in the receiving groove 211, so as to prevent the displacement of the chest of the poultry on the support member 210 caused by the movement of the poultry.

[0186] Reference Figure 29 , in some embodiments, the support member 210 includes a bottom wall 212 and two side walls 213. The two side walls 213 are respectively arranged on both sides of the bottom wall 212. The bottom wall 212 and the side walls 213 define the receiving groove 211. The bottom wall 212 is used to support the chest of the poultry, and the side walls 213 are used to support the sides of the poultry. The side walls 213 of the support member 210 can limit the position of the poultry body in the second direction, so as to avoid the displacement of the chest of the poultry on the support member 210 when fixing the poultry. The bottom wall 212 and the side walls 213 of the support member 210 can adopt a curved surface or a flat surface shape.

[0187] Reference Figure 29 , the distance between the two side walls 213 of the support member 210 gradually increases in a direction away from the bottom wall 212, so that the receiving groove 211 gradually increases from the bottom wall 212 towards the opening direction, which is convenient for putting the poultry into the receiving groove 211 and taking the poultry out of the receiving groove 211. Moreover, there are differences in the body sizes of different species and ages of poultry, and the structure in which the receiving groove 211 gradually increases from the bottom wall 212 towards the opening direction can adapt to poultry with different body sizes or shapes.

[0188] In some embodiments, one or more air holes (not shown) may be provided on the bottom wall 212 of the support member 210. The air holes are provided through the bottom wall 212 and may be connected to an air source, thereby forming a negative pressure at the air hole opening near the chest, thereby better restraining the chest of the poultry. Of course, the air source may blow air through the air hole toward the air hole opening near the chest, thereby facilitating the poultry to be blown out of the receiving slot 211 when the poultry restraint state is released.

[0189] refer to Figures 30 to 32 In some embodiments, the poultry restraint device further includes an ankle restraint mechanism 400, which is disposed on a side of the body restraint device away from the head restraint mechanism 100 and is used to restrain the ankles of the poultry.

[0190] In some embodiments, reference Figures 30 to 32 The ankle restraint mechanism 400 includes a fixing frame 410 and a locking assembly, wherein the locking assembly is connected to the fixing frame 410, and the fixing frame 410 is provided with two card slots 411, wherein the card slots 411 are used to accommodate the ankles of the poultry, and the card slots 411 have an opening for the ankles to enter, and the locking assembly is used to close the opening to restrain the ankles in the card slots 411. Among them, the fixing frame 410 is provided with two card slots 411, wherein the card slots 411 are used to accommodate the ankles of the poultry, and the card slots 411 have an opening for the ankles to enter, and the locking assembly is used to close the opening to restrain the ankles in the card slots 411. Of course, a card block may be separately provided on the fixing frame 410, and the card block is provided with a card slot 411, and the card slot 411 has an opening for the ankles to enter, and the locking portion 421 of the locking member 420 may move away from or toward the card block, so that the opening is in an open or closed state.

[0191] refer to Figure 30 and Figure 31 In one embodiment, the locking assembly may adopt a linkage structure. For example, the locking assembly includes a linkage locking assembly and two locking members 420. The linkage locking assembly includes a driving member 430 and a return member 440. The locking member 420 includes a locking portion 421 and an abutment portion 422. The locking portion 421 is located beside the opening. The abutment portion 422 can be respectively abutted against the two sides of the driving member 430. Moving the driving member 430 can push the abutment portion 422 to move the locking portions 421 away from each other to open the opening. The return member 440 is used to drive the locking members 420 to move toward each other to close the opening.

[0192] The locking assembly further includes a pushing member 450. The pushing member 450 is connected to the driving member 430 and is located on the side of the card slot 411 away from the opening. When the driving member 430 moves towards the opening direction of the card slot 411, it can drive the pushing member 450 to move towards the opening direction to push out the ankle constrained in the card slot 411 from the opening. Specifically, the two locking assemblies are slidably connected to the fixing frame 410, and a restoring member 440 is connected between the two locking members 420. The restoring member 440 can be an elastic member, such as a spring, a torsion spring, etc. The restoring member 440 provides an elastic force to make the locking members 420 move towards each other to close the opening.

[0193] In some embodiments, a first release member 460 is further connected to the driving member 430. The first release member 460 moves along the third direction with the driving member 430 and is used to push the engaging member 512 of the femur constraint mechanism 500 to move along the second direction to release the femur constraint. This solution will be described in detail later. Among them, referring to Figure 31 , one end of the abutting portion 422 close to the driving member 430 is arc-shaped, and the driving member 430 has an inclined surface 431 with a certain inclination angle at one end close to the abutting portion 422. Thus, when the driving member 430 moves close to the abutting portion 422, the inclined surface 431 at one end of the driving member 430 contacts the abutting portion 422, and as the driving member 430 moves, the inclined surface 431 at one end of the driving member 430 contacts and relatively moves with the arc surface of the abutting member, thereby pushing the locking portion 421 to move away from each other. A pulley 423 is arranged on the abutting portion 422. The pulley 423 is rotatably connected to the abutting portion 422 and is arranged corresponding to the inclined surface 431 of the driving member 430. During the movement of the driving member in the third direction, it can abut against the pulley 423 to push the abutting portion 422 to move away from each other through the pulley 423, so that the locking portion 421 opens the opening of the card slot 411.

[0194] Referring to Figure 25 、 Figure 26 and Figure 32, in combination with the above embodiments, in the femoral constraint mechanism 500, a boss 560 is further provided on the clamping member 512 or the mounting base 540. The boss 560 protrudes from the clamping member 512. A first release member 460 is further connected to the driving member 430 of the ankle constraint mechanism 400. While the driving member 430 moves along the third direction and pushes the locking member to open the slot opening for restraining the ankle, the first release member 460 moves along the third direction with the driving member 430 and can abut against the boss 560, and is used to push the boss 560 to move along the second direction, so as to push the clamping member 512 of the femoral constraint mechanism 500 to move to release the restraint on the femur. Wherein, an inclined abutting surface 461 is provided on one side of the first release member 460. The abutting surface 461 is inclined towards the direction between the clamping members 512. The inclined abutting surface 461 can push the clamping member 512 along the second direction while moving along the third direction, and the structure is simple and reliable. In some embodiments, the boss 560 can be provided only on one clamping member 512. When the boss 560 is pushed, the clamping member 512 connected to the boss 560 can drive another clamping member 512 to move synchronously through the linkage mechanism 530 introduced above, thereby realizing the opening of the clamping member 512. Wherein, the boss 560 can be a protruding structure formed on the clamping member 512, or is connected to a set position of the clamping member 512 by a connection method, refer to Figure 15 , in this embodiment, the boss 560 on the clamping member 512 is formed by a pulley connected to the clamping member 512. The pulley protrudes from the clamping member 512 to form the boss 560. The pulley is rotatably connected to the clamping member 512, so that when it abuts against the abutting surface 461 of the first release member 460 and is pushed, the rotation of the pulley can reduce the frictional resistance, thereby avoiding jamming and helping to reduce wear and increase the service life.

[0195] In this embodiment, the restoring force provided by the restoring member 440 enables the locking portions 421 to move towards each other, thereby realizing automatic locking. The driving member 430 drives the abutting portion 422 to move so that the locking portions 421 move away from each other, thereby opening the opening, and further realizing the restraint and release of the ankle. And the pushing member 450 can push the ankle of the poultry out of the slot 411. Further, after the poultry is detected, the ankle of the poultry can be automatically pushed out of the slot 411 without manually pulling out the ankle of the poultry, thereby realizing automation and improving the breeding efficiency of the poultry.

[0196] In another embodiment, the locking assembly includes a locking driving member and two locking members 420. The locking member 420 includes a locking portion 421 and a driving portion 424. The driving portion 424 is connected to the locking driving member. The locking portion 421 is correspondingly located on one side of the opening. The locking driving member drives the locking portion 421 to move relative to the fixing frame 410 to open or close the opening. The locking driving member drives the locking portion 421 to move towards the slot 411 of the fixing frame 410. When contacting the slot, the opening is in a closed state. The locking driving member drives the locking portion 421 to move away from the slot of the fixing frame 410, and the opening is opened. Wherein, the locking portion 421 and the driving portion 424 may be an integral structure or divided into two components. The locking portion 421 is connected to the driving portion 424 by a conventional connection method. Wherein, the locking driving member may adopt a conventional power mechanism capable of outputting linear motion, such as a linear module, a cylinder, an electric cylinder, etc. The reciprocating motion of the locking member can be driven by the locking driving member to open or close the opening of the slot. In this embodiment, the locking driving member directly drives the locking portion 421 to move, thereby realizing the opening and closing of the opening, and further realizing the restraint and release of the ankle.

[0197] In another embodiment, the locking member 420 can open or close the opening by rotation. Specifically, the locking assembly includes two locking members 420. The locking member 420 includes a locking portion 421 and a connecting portion 221. The connecting portion 221 is rotatably connected to the fixing frame 410 and is located beside the slot 411. The locking member 420 can rotate relative to the fixing frame 410 to make the locking portion 421 open or close the opening.

[0198] Further, the direction of the slot 411 has an opening portion 412, a protruding portion 413, and a bayonet portion 414. The driving member 430 drives the locking portion 421 to move relative to the protruding portion 413, so that the locking portion 421 approaches or contacts the protruding portion 413, thereby making the opening in a closed state. The driving member 430 drives the locking portion 421 to move away from the protruding portion 413, so that the locking portion 421 is away from the protruding portion 413, thereby making the opening in an open state. Wherein, the opening portion 412 is provided with a first radian, the buckle portion is provided with a second radian, and the locking portion 421 is provided with a third radian. When the locking portion 421 approaches or contacts the protruding portion 413, an opening for the ankle to enter is formed, and a bayonet is formed at the slot 411. The ankle of the poultry can be accommodated at the bayonet.

[0199] Further, the poultry restraint device further includes a first release member 460 and a second release member 470. The first release member 460 and the second release member 470 are respectively connected to the driving member 430. The first release member 460, the second release member 470, and the pushing member 450 can be linked. The first release member 460 is used to push the femur restraint mechanism 500 into an open state, so that the femur part of the poultry is not restrained. The second release member 470 can push the lower part near the abdomen of the poultry, so that the poultry body part can be moved away from the poultry restraint device. The pushing member 450 can automatically push the ankle of the poultry out of the card slot 411. Thus, the above linkage method can make the poultry in a released state. Thus, after the poultry is sex-identified, fed, or vaccinated, it will automatically fall into the device for accommodating the poultry. For example, after the poultry is sex-identified, through the above linkage method, the poultry will automatically fall into the sorting device for the next sorting work.

[0200] Based on the above embodiments, the relative movement between the support mechanism 200 and the ankle restraint mechanism 400 can be used to achieve the stretching of the legs and the adjustment of the body. For example, the support mechanism 200 can be moved relative to the ankle restraint mechanism 400 to move the poultry body at least in the third direction away from the ankles to achieve the stretching of the legs; or, the ankle restraint mechanism 400 can be moved relative to the support mechanism 200 to move the poultry ankles at least in the third direction away from the body to achieve the stretching of the legs; or, the ankle restraint mechanism 400 and the support mechanism 200 can move away from each other to move the poultry ankles and body at least in the third direction away from each other to achieve the stretching of the legs. Thus, the adjustment of the positions of the body and ankles is achieved through the stretching of the legs. Among them, the relative movement between the support mechanism 200 and the ankle restraint mechanism 400 can be achieved through the lifting mechanism 600 and / or the ankle stretching mechanism. For example:

[0201] The body restraint device may include a support mechanism 200 and a lifting mechanism 600; wherein, the support mechanism 200 is used to restrain the chest and / or abdomen of the poultry; the ankle restraint mechanism 400 is disposed adjacent to the support mechanism 200 and is used to restrain the ankles of the poultry; the lifting mechanism 600 is connected to the support mechanism 200 and is used to lift the support mechanism 200 at least in the third direction. Thus, the abdomen of the poultry restrained by the body restraint device can be lifted in a direction away from the ankles, so that the legs can be stretched, and the adjustment of the poultry restraint posture is achieved.

[0202] Alternatively, the body restraint device includes a support mechanism 200, and the ankle restraint mechanism 400 includes an ankle stretching mechanism; wherein, the support mechanism 200 is used to restrain the chest and / or abdomen of the poultry; the ankle restraint mechanism 400 is disposed adjacent to the support mechanism 200 and is used to restrain the ankles of the poultry; the ankle stretching mechanism is connected to the ankle restraint mechanism 400 and is used to drive the ankle restraint mechanism 400 to move to stretch the ankles of the poultry in a direction away from the body of the poultry. Thus, the ankles of the poultry restrained by the body restraint device can be stretched away from the body, so that the legs can be stretched, and the adjustment of the restraint posture of the poultry can be realized.

[0203] Alternatively, the body restraint device includes a support mechanism 200 and a lifting mechanism 600, and the ankle restraint mechanism 400 includes an ankle stretching mechanism; wherein, the support mechanism 200 is used to restrain the chest and / or abdomen of the poultry; the ankle restraint mechanism 400 is disposed adjacent to the support mechanism 200 and is used to restrain the ankles of the poultry; the lifting mechanism 600 is connected to the support mechanism 200 and is used to lift the support mechanism 200 at least in the third direction; the ankle stretching mechanism is connected to the ankle restraint mechanism 400 and is used to drive the ankle restraint mechanism 400 to move to stretch the ankles of the poultry in a direction away from the body of the poultry. Thus, the ankles and the body of the poultry restrained by the body restraint device can be stretched away from each other, so that the legs can be stretched, and the adjustment of the restraint posture of the poultry can be realized.

[0204] In the above embodiment, the support mechanism 200 restrains the abdomen and / or chest of the poultry through the abdominal support mechanism 201 and / or the chest support mechanism 202, and cooperates with the ankle restraint mechanism 400 to restrain the ankle position of the poultry, so that the poultry can be better fixed and the posture can be adjusted. Thus, when restraining the poultry, the poultry can be placed in any posture with the head facing the first direction on the posture adjustment device of the embodiment of the present application. The abdomen of the poultry body is restrained and lifted at least in the third direction through the support mechanism 200, and the ankles of the poultry are restrained through the ankle restraint mechanism 400, so as to realize the restraint of the body and the adjustment of the posture. The requirement for the placement posture of the poultry is reduced, and the consistency of the posture of the poultry during batch operation is effectively guaranteed, which helps to improve the efficiency of processing the poultry and is applicable to the mechanized processing operation of the poultry. In addition, due to the restraint effect of the ankle restraint mechanism 400 on the ankles, when the abdomen of the body is lifted, the poultry presents a posture with the buttocks lifted and the legs stretched, which can avoid the problem of the body position shifting caused by the struggling of the poultry legs, so that the required posture remains unchanged, which helps the subsequent processing operation and improves the accuracy of the operation.

[0205] As can be seen from the above embodiments, the poultry restraint device of the embodiments of the present application can effectively restrain the position of the poultry body, avoid the problem of the body position shifting caused by the struggling of the poultry head, has a high restraint accuracy, helps the smooth progress of subsequent processing operations, and is especially suitable for the poultry restraint requirements in precise operations, such as the in-vivo and in-vitro processing operations of the body or other parts. Among them, the restraint of the femur position can improve the accuracy of body restraint, thereby improving the success rate of the operation and reducing the harm to the poultry.

[0206] In a second aspect of the embodiments of the present application, a poultry restraint method is provided, which is applied to a poultry restraint device including a body restraint device. The method includes: being applied to a poultry restraint device including a body restraint device and a femur restraint mechanism 500. The method includes: placing the body restraint device of the poultry restraint device on the poultry; the poultry restraint device applies a first force to the poultry. Under the first force, at least the femur of the poultry abuts against the femur restraint mechanism 500 along a first direction. From the bone characteristics of the poultry mentioned above, it can be seen that the restraint of the femur position can effectively restrain the position of the poultry body, and the position of the femur is determined, which can effectively avoid the body displacement. Therefore, based on this poultry restraint method, effective restraint of the femur in the first direction can be achieved, thereby achieving efficient and precise restraint of the poultry.

[0207] In some embodiments, the poultry restraint device applies a first force to the poultry. Under the first force, at least the femur of the poultry abuts against the femur restraint mechanism 500 along a first direction, including:

[0208] The poultry restraint device applies a pulling force to at least the head or neck of the poultry in at least the first direction. Under the pulling force, at least the femur of the poultry abuts against the femur restraint mechanism 500 along a first direction; thus, it can be seen that in this embodiment, the first force is the above-mentioned pulling force;

[0209] Or, the poultry restraint device applies a pushing force to at least the tail or femur of the poultry body in at least the first direction. Under the pushing force, at least the femur of the poultry abuts against the femur restraint mechanism 500 along a first direction; thus, it can be seen that in this embodiment, the first force is the above-mentioned pushing force;

[0210] Or, the poultry restraint device applies a pulling force to at least the head or neck of the poultry in at least the first direction, and applies a pushing force to at least the tail or femur of the poultry body in at least the first direction. Under the action of the pulling force and the pushing force, at least the femur of the poultry abuts against the femur restraint mechanism 500 along a first direction; thus, it can be seen that in this embodiment, the first force is the sum of the above-mentioned pulling force and pushing force.

[0211] The restraint method of the embodiment of the present application can be applied to the poultry restraint device of the embodiment of the first aspect above. When applied, the poultry restraint device restrains the femur of the poultry at the first position at least in the first direction, so that the femur of the poultry abuts against the femur restraint mechanism 500. Specifically, by restraining the head or the tail of the body of the poultry, the femur can be located at the first position. The poultry restraint device restrains the head of the poultry at the second position at least in the first direction. The second position is configured as the position of the head when the neck of the poultry is stretched. Different-sized poultry have different neck lengths. Therefore, the second position in this method is not limited to a specific position and varies according to the size of the poultry. In addition, as can be seen from the poultry restraint device of the embodiment of the first aspect above, the head of the poultry can also be pulled at least in the first direction by the self-adaptive stretching of the constant force mechanism until the neck is stretched, and at this time the head is located at the second position. This method restrains the femur of the poultry at the first position by restraining the head at the second position. The poultry restraint device of the embodiment of the first aspect of the present application can be used to implement the above restraint method. For example, through the head restraint mechanism 100, the stretching device 130, and the femur restraint mechanism 500 of the above embodiment, the head is pulled at least in the first direction to the second position to stretch the neck, and the femur of the body is moved at least in the first direction to the first position and abuts against the femur restraint mechanism 500 to achieve the restraint of the femur position.

[0212] Alternatively, in some other embodiments, the method for the poultry restraint device to restrain the femur of the poultry at the first position at least in the first direction includes: the poultry restraint device restrains the tail of the poultry body at the third position at least in the first direction. The third position is configured as the position where the tail of the poultry body is pushed in the first direction until the femur is moved and restrained at the first position. The third position is configured as the position of the tail of the poultry body when the body of the poultry is pushed until the femur abuts against the femur restraint mechanism 500. Different-sized poultry have different body shapes. Therefore, the third position in this method is not limited to a specific position and varies according to the size of the poultry. In addition, as can be seen from the poultry restraint device of the embodiment of the first aspect above, the tail of the poultry body can also be pushed at least in the first direction by the self-adaptive stretching of the constant force mechanism until the femur abuts against the femur restraint mechanism 500, and at this time the tail of the body is located at the third position. The poultry restraint device of the embodiment of the first aspect of the present application can be used to implement the above restraint method. For example, through the pushing device and the femur restraint mechanism 500 of the above embodiment, the tail of the body is pushed at least in the first direction to move the femur at least in the first direction to the first position and abut against the femur restraint mechanism 500 to achieve the restraint of the femur position.

[0213] In some embodiments, the poultry restraint device stretches the head of the poultry at least in a first direction to a second position to stretch the neck, and retracts at least in the negative direction of the first direction until the head reaches the release position to relax the neck of the poultry. Thus, after the relevant processing operation on the poultry is completed, it is convenient to release the poultry. Different release positions can be preset according to the size of the poultry. The head of the poultry is retracted at least in a second direction by the poultry restraint device to reach the set release position, so that the neck of the poultry is released from the stretched state in the first direction, or the poultry to be restrained is adapted to be restrained by the poultry restraint device, facilitating the release of the poultry and the placement of the next poultry to be restrained. It can be understood that the above release position can be a definite position or a range in the first direction, as long as the head reaching this position can release the neck of the poultry, so as to move the poultry out of the poultry restraint device after the processing operation. For example, a release position can be set respectively for the neck sizes of chicks and adult chickens. Therefore, corresponding to the restraint of chicks or adult chickens, the head restraint mechanism 100 can be moved from the zero position to the corresponding release position, which can facilitate the restraint of the head of the chicks or adult chickens on the head restraint mechanism 100, facilitate the stretching of the neck, and move the poultry out of the poultry restraint device after the processing operation, avoiding too long travel and required time for stretching and removal, which affects the restraint efficiency of the device.

[0214] In some embodiments of the poultry restraint method, the poultry restraint device also includes: restraining the back of the poultry at least in a third direction. The poultry restraint device restrains the abdomen and / or chest of the poultry at least in the third direction, so that the back of the poultry is restrained at least in the third direction, thereby realizing the restraint of the body position in the third direction. The method can be implemented by using the poultry restraint device of the first aspect embodiment of the present application. The back restraint mechanism 300 is set at a set position, and by lifting the abdomen and / or chest of the poultry through the abdominal support mechanism and / or the chest support mechanism, the back of the poultry can be lifted to be restrained on the back restraint mechanism 300 to realize the restraint in the third direction. Specifically, the poultry restraint device restrains the back of the poultry at least in the third direction, and lifts the abdomen and / or chest of the poultry at least in the third direction to restrain the abdomen and / or chest of the poultry at least in the third direction, so that the back of the poultry is restrained at least in the third direction.

[0215] In some embodiments of the restraint method, the poultry restraint device adsorbs the back of the poultry at least in the third direction to realize the restraint of the back. This method can be applied to the poultry restraint device in some of the above embodiments. The back restraint mechanism 300 adsorbs the back of the poultry to a fourth position. Thus, through the way of back adsorption, the body of the poultry can also be restrained in the third direction.

[0216] In some embodiments, the poultry restraint method further includes: the poultry restraint device restrains the ankles of the poultry. The poultry is further restrained by restraining the ankles. During implementation, the restraint of the ankles can be achieved by the poultry restraint device according to the embodiments of the first aspect above. For example, on the side of the body restraint device facing away from the head of the poultry, the ankles of the poultry are restrained at least in the second direction and the first direction. The ankles of the two feet of the poultry are distributed in the second direction. Thus, the ankles of the two feet of the poultry are restrained by the ankle restraint mechanism 400, so that the ankles can be respectively restrained at least in the second direction and thus cannot rotate around the third direction. Thus, the body can be prevented from deflecting around the third direction, ensuring the position certainty of the body in the second direction, and realizing the restraint positioning of the body and the adjustment of the posture. Restraining the ankles of the poultry at least in the second direction can effectively adjust the relative positions of the ankles and the body, thus effectively restraining and adjusting the posture of the poultry body, preventing the body from deflecting around the third direction, and thus contributing to the smooth progress of subsequent processing operations.

[0217] In some embodiments, the poultry can be restrained by the poultry restraint device according to the embodiments of the first aspect above. The chest and / or abdomen of the poultry are restrained at least in the third direction by the support mechanism, thereby realizing the support of the body and the positioning in the third direction. It can be understood that the ankles of the two feet of the poultry are distributed in the second direction. Thus, the ankles of the two feet of the poultry are restrained by the ankle restraint mechanism 400, so that the ankles can be respectively restrained at least in the second direction and thus cannot rotate around the third direction. Thus, the body can be prevented from deflecting around the third direction, ensuring the position certainty of the body in the second direction, and realizing the restraint positioning of the body and the adjustment of the posture.

[0218] In the poultry restraint method according to the embodiments of the present application, the order of each step can be adaptively adjusted according to actual needs to effectively restrain the poultry.

[0219] As can be seen from the above, the poultry restraint device and restraint method according to the embodiments of the present application can be applied to the processing operations during the cultivation of poultry to restrain the poultry, can effectively restrain the position of the body, avoid the problem of the body position shifting caused by the struggling of the poultry head, and thus contribute to the smooth progress of subsequent processing operations. In particular, it is applicable to the auxiliary restraint during the processing operations of the internal and external parts of the body, ensuring the accuracy of the operations.
