Description

Technical Field

[0001] The invention belongs to the technical field of animal husbandry processing, and in particular relates to an egg sorting structure and hatching equipment. Background Art

[0002] Before incubating poultry eggs, it is necessary to screen out unqualified eggs with dark lines, cracks, loose yolk, deformities, and sandy skin, and to classify the eggs into different grades according to their weight;

[0003] The current screening and grading method is still commonly carried out by manual sorting: workers observe the breeding eggs with the naked eye, feel the weight of the breeding eggs with their hands, and weigh and grade them according to experience. Undoubtedly, this sorting method is time-consuming and labor-intensive, and there may be errors between the weight of the sorted eggs and the actual weight.

[0004] With the rapid development of technology, mechanical equipment that can perform automatic or semi-automatic sorting has been designed. The eggs are transferred to a weighing tray by means of a robot that clamps them. After weighing, the robots transfer the eggs accordingly. The weighing and sorting are performed by multiple clamping operations, which poses a risk of damaging the eggs.

[0005] Therefore, it becomes a technical problem that needs to be solved urgently by those skilled in the art.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The present invention provides a poultry egg sorting structure. A sorting sleeve is provided. The sorting sleeve cooperates with a connecting part and a trigger part so that the sorting sleeve drives the connecting structure to slide downward and is squeezed by an inclined surface to gradually move in a direction away from the axis of a sorting platform, thereby realizing different overall distances from the sorting platform according to different weights of poultry eggs in the sorting sleeve.

[0008] Another object of the present invention is to provide an incubation device.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: an egg sorting structure, comprising a conveyor belt, wherein a plurality of conveyor tracks are arranged on the conveyor belt along the front-rear direction; comprising:

[0011] A plurality of sorting sleeves are used to hold eggs, and each sorting sleeve is connected to each connecting part respectively;

[0012] The trigger part has at least one inclined surface, which extends outward and downward gradually from the axis of the sorting platform. When eggs are placed, the sorting sleeve drives the connecting structure to slide downward and is squeezed by the inclined surface to gradually move away from the axis of the sorting platform.

[0013] Furthermore, the connection structure also includes:

[0014] A fixing rod is vertically arranged on the sorting table;

[0015] A connecting block is slidably sleeved on the fixing rod, wherein the connecting portion is perpendicular to the side wall of the connecting block and connected to the side wall;

[0016] A connecting plate is arranged on the outer peripheral wall of the sorting sleeve, the connecting plate is slidably connected with the connecting part, and a first return spring is sleeved on the outside of the connecting part.

[0017] Furthermore, it also includes:

[0018] A plurality of levers are arranged along the extension direction of the connecting portion, one end of which is hinged to the outer wall of the sorting table;

[0019] A plurality of telescopic sleeves are obliquely arranged on the outer wall of the sorting platform, one end of the telescopic sleeve is hinged to the side wall of the sorting platform, and the other end is hinged to the side wall of the lever;

[0020] The connecting block is disposed against the lever.

[0021] Furthermore, the sorting sleeve comprises two half-sorting sleeves, each of which is provided with a connecting arm, and a free end of the connecting arm is rotatably connected to the connecting plate along a vertical direction, and the rotation directions thereof are opposite.

[0022] Furthermore, a rotation reset mechanism is provided between the connecting arm and the connecting plate, for resetting the connecting arm after rotation; the rotation reset mechanism comprises:

[0023] A rotating shaft connected to the connecting arm, wherein the connecting arm is rotatably connected to the connecting plate via the rotating shaft, and a gear is disposed on an outer peripheral wall of the rotating shaft;

[0024] A rack, movable along an axial direction perpendicular to the rotation axis, wherein the rack is meshed with the gear;

[0025] The fixed guide rod is arranged perpendicular to the axial direction of the rotating shaft, the rack is slidably arranged on the fixed guide rod, and a second return spring is also sleeved on the fixed guide rod.

[0026] Furthermore, the outer peripheral wall of the sorting platform is provided with a plurality of installation grooves recessed along its radial direction at intervals, and the connection structure and the trigger part are arranged in the installation grooves;

[0027] The top of the sorting table is provided with a plurality of through holes at intervals, which are connected with the mounting grooves;

[0028] The sorting table is vertically provided with a partition assembly, which is used to rotate each through hole of the sorting table to the partition assembly to separate the two half sorting sleeves.

[0029] Furthermore, the partition assembly includes:

[0030] A fixed plate, arranged on the sorting table;

[0031] A sliding guide rod is vertically slidably connected to the fixed plate, and a compression spring is sleeved on the outer side of the sliding guide rod;

[0032] The wedge block is connected to one end of the sliding guide rod. When the through hole is opposite to the wedge block, the two oblique sides of the wedge block are against the connecting arm through the compression spring rebound.

[0033] The present invention also provides an incubation device having any of the above-mentioned egg sorting structures.

[0034] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0035] 1. The present invention provides a sorting sleeve, and the sorting sleeve cooperates with the trigger part through the connection part, so that the sorting sleeve drives the connection structure to slide downward and is squeezed by the inclined surface to gradually move in the direction away from the axis of the sorting table, so that the overall distance from the sorting table can be different according to the different weights of the poultry eggs in the sorting sleeve.

[0036] 2. The present invention provides a lever and a telescopic sleeve, wherein the lever is rotatably connected to the sorting platform, and the other end is hinged to the telescopic sleeve which is obliquely hinged to the outer wall of the sorting platform. When eggs of different weights are placed in the telescopic sleeve, the amount of their oblique downward movement is obviously different. Therefore, when eggs of different weights are pressed down, the movement range of the sorting sleeve is larger, so that they can be distributed in different conveying tracks as much as possible, ensuring that the sorting of eggs is more accurate.

[0037] 3. The present invention divides the sorting sleeve into two half-sorting sleeves, each of which is provided with a connecting arm, and the free end of the connecting arm is rotatably connected to the connecting plate along the vertical direction. The half-sorting sleeve can be rotated and opened in the opposite direction, so that the poultry eggs contained therein are placed on the corresponding conveying track, thereby facilitating the separation of the poultry eggs from the sorting sleeve and ensuring the subsequent conveying operation of the poultry eggs.

[0038] 4. The present invention arranges a separation component on the sorting table, and can separate the two connecting arms through the through hole, so that the opening operation of the corresponding sorting sleeve can be realized, which effectively liberates manual labor and saves time and effort.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0054] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0055] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] like Figures 1 to 7As shown, an egg sorting structure described in the present invention comprises a conveyor belt 2, on which a plurality of conveyor tracks 21 are arranged along the front-rear direction. The entire egg sorting structure is arranged on a base 1 or is fixed on the ground of a production workshop by bolts. The entire egg sorting structure comprises a conveying assembly arranged on the base 1, which is used to send the eggs one by one into a subsequent sorting structure. Specifically, the conveying assembly comprises a conveying bracket, which is composed of a vertical support frame 3 and a conveying slide 31 arranged obliquely downward. The cross section of the conveying slide 31 is U-shaped, and a rotatable separating wheel 32 is arranged in the conveying slide 31. The two ends of the separating wheel 32 are rotatably connected to the side wall of the conveying slide 31 through a rotating shaft. The separating wheel 32 is composed of a plurality of separating plates arranged at equal intervals along its circumference, and the clamping groove formed by adjacent separating plates is slightly larger than the volume of a normal egg, so that during the rotation process, only one egg can enter the clamping groove between each two adjacent separating plates at a time. The separation wheel 32 is driven by the driving motor 11, and the driving motor 11 can select the servo motor 1b, so as to accurately control the timing and angle of rotation of the separation wheel 32, so as to accurately put the poultry eggs into the structure of the next sorting process, which will be described in detail later.

[0057] In the existing sorting equipment, the eggs are usually clamped, transferred, weighed and sorted by a robot. However, it is difficult to control the clamping force, which can easily cause damage to the eggs. On the other hand, sorting is done manually based on experience, resulting in large sorting errors and is time-consuming and labor-intensive.

[0058] In order to overcome the above-mentioned technical defects, the present invention makes corresponding technical improvements:

[0059] The sorting structure includes a sorting platform 5 that can rotate around its axis, and a plurality of vertically slidable connecting structures 6 are evenly spaced on the outer peripheral wall of the sorting platform 5, and the connecting structure 6 at least includes a connecting portion 63 extending along the radial direction of the sorting platform 5;

[0060] A plurality of sorting sleeves 4 are used to hold eggs, and each sorting sleeve 4 is connected to each connecting portion 63;

[0061] The trigger portion 62 is disposed on the sorting platform 5 and has at least one inclined surface 621, which extends gradually downward from the axis of the sorting platform 5. When eggs are placed, the sorting sleeve 4 drives the connecting structure 6 to slide downward and is squeezed by the inclined surface 621 to gradually move away from the axis of the sorting platform 5.

[0062] In the present invention, a sorting bracket is arranged on the base 1, and the sorting bracket includes at least a plurality of vertically arranged gantry brackets 1a, and a sorting platform 5 is arranged at one end of one of the gantry brackets 1a. Specifically, the sorting platform 5 is cylindrical, and the gantry bracket 1a is located directly below the sorting platform 5. The sorting platform 5 is rotatably connected to the gantry bracket 1a through a rotating shaft 81, so that the sorting platform 5 can rotate around its axis. A plurality of connecting structures 6 are arranged at equal intervals on the periphery of the sorting platform 5, and the number of the connecting structures 6 is preferably 3, that is, the angle of each connecting structure 6 is preferably 120°. Of course, the number of the connecting structures 6 can be 2 or more than 4.

[0063] Specifically, the connection structure 6 can slide vertically relative to the height direction of the sorting platform 5, and the connection structure 6 is provided with a connection portion 63 extending horizontally along the radial direction of the sorting platform 5. A sorting sleeve 4 is also included, which is sleeved on the connection portion 63 and can slide along the extension direction of the connection portion 63. A trigger portion 62 corresponding to the connection portion 63 in each connection structure 6 is also provided on the sorting platform 5, and the trigger portion 62 includes an inclined surface 621. When eggs are placed in the sorting sleeve 4, the connection portion 63 slides vertically relative to the sorting platform 5 under the action of gravity, so that it contacts and presses with the inclined surface 621 during the sliding process, so that the sorting sleeve 4 moves along the extension direction of the connection portion 63 in a direction away from the axis of the sorting platform 5, so that the entire sorting sleeve 4 moves downwardly relative to the sorting platform 5.

[0064] According to the different weights of the eggs in the sorting sleeve 4, the overall distance from the sorting platform 5 is different. With the different conveying tracks 21 on the conveyor belt 2, the automatic sorting operation can be easily performed according to the weight of the eggs. Since the entire sorting platform 5 can rotate, it can cooperate to achieve continuous sorting action, and can be manually picked up or automatically put down from the bottom of the sorting sleeve 4, and the entire sorting action saves time and effort.

[0065] Furthermore, the connection structure 6 also includes:

[0066] A fixing rod 66 is vertically arranged on the sorting platform 5;

[0067] The connecting block 65 is slidably mounted on the fixing rod 66, and the connecting portion 63 is perpendicular to the side wall of the connecting block 65 and connected to the side wall;

[0068] A connecting plate 69 is provided on the outer peripheral wall of the sorting sleeve 4 , and the connecting plate 69 is slidably connected to the connecting portion 63 . A first return spring 64 is sleeved on the outside of the connecting portion 63 .

[0069] In the present invention, a vertical fixing rod 66 is provided on the sorting platform 5, which does not contact the outer peripheral wall of the sorting platform 5, and the connecting block 65 is slidably mounted on the fixing rod 66, so that it can have the freedom of sliding in the height direction relative to the sorting platform 5. Specifically, the connecting block 65 is a strip structure, and its plate surface is perpendicular to the extension direction of the connecting portion 63, and one end of the connecting portion 63 extends in the opposite direction and is connected to the connecting block 65. In order to facilitate the sorting sleeve 4 to slide relative to the connecting portion 63, a connecting plate 69 is provided on its outer wall, wherein the connecting plate 69 is provided with a through hole 525 for the connecting portion 63 to penetrate. By mounting the connecting plate 69 on the connecting portion 63, the assembly action of the sorting sleeve 4 on the sorting platform 5 is completed. In addition, a stop shoulder is provided at the end of the extension end of the connecting portion 63, and a first return spring 64 is mounted on the outside thereof, wherein the two ends of the first return spring 64 are respectively against the stop shoulder and the connecting plate 69. By providing the first reset spring 64, the sorting sleeve 4 can be automatically reset after moving relative to the axis of the sorting platform 5, thereby ensuring that subsequent sorting actions are carried out normally.

[0070] Furthermore, it also includes:

[0071] A plurality of levers 67 are arranged along the extension direction of the connecting portion 63, one end of which is hinged to the outer wall of the sorting platform 5;

[0072] A plurality of telescopic sleeves 68 are obliquely arranged on the outer wall of the sorting platform 5, one end of the telescopic sleeve 68 is hinged to the side wall of the sorting platform 5, and the other end is hinged to the side wall of the lever 67;

[0073] The connecting block 65 is disposed against the lever 67 .

[0074] In the present invention, a lever 67 is rotatably connected to the outer wall of the sorting platform 5, and the other end of the lever 67 is hinged through a telescopic sleeve 68 that is obliquely hingedly arranged on the outer wall of the sorting platform 5. Specifically, the telescopic sleeve 68 includes a telescopic rod, a cylinder body, and a third return spring. The telescopic rod is slidably arranged in the cylinder body, and the third return spring is arranged in the cylinder body, one end of which is connected to the telescopic rod. That is, one end of the telescopic rod is hinged to the free end of the lever 67 or the side wall away from the hinge point of the lever 67 and the sorting platform 5, wherein the telescopic sleeve 68 forms a diagonal support component.

[0075] Preferably, the telescopic rod is hinged to one third of the side wall of the lever 67, and the connecting block 65 is in contact with two thirds of the upper side wall of the lever 67. Through the principle of the lever 67, due to the distribution of the telescopic rod and the connecting block 65 at the action point of the lever 67, and the inclined setting of the telescopic rod, the telescopic rod and the third return spring of the connecting block 65 increase nonlinearly without the action of gravity.

[0076] That is, when eggs of different weights are placed in the telescopic sleeve 68, the amount of their tilted downward movement is obviously different. Therefore, when eggs of different weights are pressed down, the movement range of the sorting sleeve 4 is larger, so that they can be distributed in different conveying tracks 21 as much as possible, ensuring that the sorting of eggs is more accurate.

[0077] Furthermore, the sorting sleeve 4 includes two half sorting sleeves 41, each of which is provided with a connecting arm 61, and the free end of the connecting arm 61 is rotatably connected to the connecting plate 69 along the vertical direction, and the rotation directions thereof are opposite.

[0078] In the present invention, the sorting sleeve 4 is composed of two half-sorting sleeves 41, and the sorting sleeve 4 is a cylindrical structure with a closed bottom and an open top. A connecting arm 61 is provided on the outer wall of each half-sorting sleeve 41, extending horizontally perpendicular to the cylinder wall of the half-sorting sleeve 41, and the extended free end and the side wall of the connecting plate 69 have a rotatable degree of freedom in the horizontal direction. That is, the half-sorting sleeve 41 can be horizontally rotated relative to the connecting plate 69 along with the connecting arm 61, and the two half-sorting sleeves 41 can be rotated in opposite directions to open, so that the poultry eggs contained therein are placed on the corresponding conveying track 21, so as to facilitate the poultry eggs to be separated from the sorting sleeve 4 and ensure the subsequent poultry egg transportation operation.

[0079] Furthermore, a rotation reset mechanism 8 is provided between the connecting arm 61 and the connecting plate 69, for resetting the connecting arm 61 after rotation; the rotation reset mechanism 8 includes:

[0080] A rotating shaft 81 connected to the connecting arm 61, wherein the connecting arm 61 is rotatably connected to the connecting plate 69 via the rotating shaft 81, and a gear 82 is disposed on the outer peripheral wall of the rotating shaft 81;

[0081] The rack 83 can move along the axial direction perpendicular to the rotating shaft 81, wherein the rack 83 is meshed with the gear 82;

[0082] The fixed guide rod 84 is arranged perpendicular to the axial direction of the rotating shaft 81 , and the rack 83 is slidably arranged on the fixed guide rod 84 . The fixed guide rod 84 is also sleeved with a second return spring 85 .

[0083] In the present invention, a rotating shaft 81 perpendicular to the extending direction of the connecting arm 61 is provided at the free end of the connecting arm 61, and an axial hole matching the rotating shaft 81 is provided on the connecting plate 69. Specifically, a convex plate vertically protruding from the plate surface of the connecting plate 69 is symmetrically provided on the connecting plate 69, and an axial hole matching the rotating shaft 81 is provided on the convex plate, and the rotating shaft 81 is inserted into the axial hole. A gear 82 is provided on the outer wall of the rotating shaft 81, and two fixed guide rods 84 perpendicular to the plate surface are provided on the convex plate, and the second return spring 85 is sleeved on the outside of each of the two fixed guide rods 84. The upper and lower side walls of the rack 83 are symmetrically provided with guide holes that can pass through the fixed guide rod 84 and slide with it. The fixed guide rod 84 is inserted into the guide hole of the rack 83, so that the rack 83 can move along the extension direction of the fixed guide rod 84. At the same time, with the reset elastic force of the second reset spring 85, after the two connecting arms 61 drive the semi-sorting sleeve 41 to rotate, the rack 83 can be reset to the initial state by its elastic force, so that the semi-sorting sleeve 41 can automatically close after separating the poultry eggs and sending them to the corresponding conveying track 21, waiting for the next sorting action.

[0084] Furthermore, the outer peripheral wall of the sorting platform 5 is provided with a plurality of installation grooves 50 recessed along the radial direction thereof, and the connection structure 6 and the triggering part 62 are arranged in the installation grooves 50;

[0085] The top of the sorting platform 5 is provided with a plurality of through holes 525 at intervals, which are connected to the mounting groove 50;

[0086] The sorting platform 5 is vertically provided with a partition assembly 52 for rotating each through hole 525 of the sorting platform 5 to the partition assembly 52 to separate the two half sorting sleeves 41 .

[0087] In the present invention, in order to reduce the occupied space of the entire sorting structure, a plurality of mounting grooves 50 extending toward the axis are provided at equal angles on the outer peripheral wall of the sorting platform 5. The above-mentioned connecting structure 6 and the triggering part 62 are both arranged in the mounting groove 50. Specifically, it should be noted that the connecting part 63 and the triggering part 62 are both arranged in the mounting groove 50, and the connecting arm 61 extends outward from the end connected to the connecting plate 69 to the side away from the axis of the sorting platform 5 and is connected to the side wall of the sorting sleeve 4.

[0088] A through hole 525 communicating with the mounting groove 50 is provided at a corresponding position of each mounting groove 50 on the sorting platform 5, wherein the center of the through hole 525 is orthographically projected downward and is located on the midline of the interval connecting line between the two connecting arms 61. A partitioning assembly 52 is provided on the sorting platform 5, which can separate the two connecting arms 61 through the through hole 525, so as to realize the opening operation of the corresponding sorting sleeve 4, effectively liberating manual labor and saving time and effort.

[0089] Further, the partition assembly 52 includes a fixing plate 521, which is arranged on the sorting platform 5;

[0090] A sliding guide rod 522 is vertically slidably connected to the fixed plate 521, and a compression spring 523 is sleeved on the outer side of the sliding guide rod 522;

[0091] The wedge block 524 is connected to one end of the sliding guide rod 522 . When the through hole 525 faces the wedge block 524 , the compression spring 523 rebounds so that the two oblique sides of the wedge block 524 abut against the connecting arm 61 .

[0092] In the present invention, the fixed plate 521 in the partition assembly 52 is arranged above the sorting table 5, and is not rigidly connected to the side wall of the sorting table 5. Specifically, the fixed plate 521 can be connected to the base 1 by extending its own length or by an additional bracket. The fixed plate 521 is L-shaped, and two guide holes are provided through its lateral end. Two sliding guide rods 522 pass through the guide holes, and a shoulder is provided at the upper end, and a wedge block 524 is connected to the lower end. The slopes of the hypotenuses on both sides of the wedge block 524 are consistent, and a compression spring 523 is also sleeved on the sliding guide rod 522. The two ends of the compression spring 523 are respectively against the lateral end of the fixed plate 521 and the wedge block 524.

[0093] In the initial stage, the wedge block 524 is in contact with the upper end surface of the sorting platform 5, and the elastic force of the compression spring 523 makes the wedge block 524 close to the surface. Specifically, a driving motor 11 is provided on the gantry bracket 1a, and is connected to the rotating shaft 81 of the sorting platform 5 through the driving motor 11. The driving motor 11 can also be a servo motor 1b. During the rotation of the sorting platform 5, when the driving motor 11 drives a certain angle, when the wedge block 524 corresponds to the through hole 525 on the sorting platform 5, the wedge block 524 extends downward into the installation groove 50 during the process of the compression spring 523 returning to its original state, and the oblique edges on both sides thereof abut against the side walls of the two connecting arms 61. As the wedge block 524 extends in, the two connecting arms 61 are opened, so that the eggs in the sorting sleeve 4 can fall automatically. Due to the angle rotation control of the servo motor 1b, when the sorting platform 5 rotates to be perpendicular to the conveying direction of the conveying track 21, the wedge block 524 just extends into the installation slot 50 to open the sorting sleeve 4, so that the eggs fall into the corresponding conveying track 21. That is, the wedge block 524 needs to be set in front of the conveying track 21.

[0094] The present invention also provides an incubation device having an egg sorting structure according to any of the above-mentioned embodiments. An incubation device is provided at the conveying end of the conveying track 21, and an operator can perform the final incubation operation on the sorted eggs, thereby realizing overall automated processing and improving the overall hatching efficiency.

[0095] Another preferred embodiment of the present invention:

[0096] like Figures 1 to 3 , Figures 8 to 9 As shown, a poultry egg crack detection structure of the present invention comprises a sorting table 5, which can rotate around its axis, and a fixing ring 51 is arranged at the upper end of the sorting table 5, and a plurality of protrusions 511 are arranged at equal intervals on the side wall of the fixing ring 51 opposite to the sorting table 5;

[0097] A plurality of sorting sleeves 4 are arranged at equal intervals on the outer peripheral wall of the sorting platform 5, and a sorting inner cylinder 42 capable of vertical sliding is arranged in the sorting sleeve 4; a hydraulic transmission assembly 7 is arranged between the sorting inner cylinder 42 and the fixing ring 51, and is used for continuously contacting with the plurality of convex heads 511 during the process of the sorting sleeve 4 rotating with the sorting platform 5, thereby driving the sorting inner cylinder 42 to periodically slide vertically;

[0098] The illumination searchlight 10 is arranged at the bottom of the sorting sleeve 4 and is used to detect cracks on the eggs in the sorting inner cylinder 42 from bottom to top.

[0099] In the present invention, the entire egg crack detection structure is arranged on the base 1 or fixed on the ground of the production workshop by bolts. A sorting bracket is arranged on the base 1, and the sorting bracket at least includes a plurality of vertically arranged gantry brackets 1a, and a sorting platform 5 is arranged at one end of one of the gantry brackets 1a. Specifically, the sorting platform 5 is cylindrical, and the gantry bracket 1a is located directly below the sorting platform 5. The sorting platform 5 is rotatably connected to the gantry bracket 1a through a rotating shaft 81, so that the sorting platform 5 can rotate around its axis. Another gantry bracket 1a is connected to a fixing ring 51, and the entire fixing ring 51 is arranged at the upper end of the sorting platform 5, and there is a spacing between the opposite side walls of the two, and they are not in contact. The lower end face of the fixing ring 51 can at least be completely projected on the end face of the sorting platform 5. A plurality of equally spaced protrusions 511 are arranged on the side wall opposite to the sorting platform 5, and the protrusions 511 are hemispherical.

[0100] A plurality of sorting sleeves 4 are arranged at equal intervals on the side wall of the sorting platform 5. The top of the sorting sleeve 4 is open and has a storage space inside. A sorting inner cylinder 42 is slidably connected in the storage space of the sorting sleeve 4. A hydraulic transmission assembly 7 is arranged between the sorting sleeve 4 and the fixing ring 51, so that when the sorting platform 5 rotates, the hydraulic transmission assembly 7 can sequentially press and contact with the convex head 511, so that the sorting inner cylinder 42 can slide up and down relative to the sorting sleeve 4. The sorting inner cylinder 42 also has an open upper end and a storage space inside, and the storage space in the sorting inner cylinder 42 is slightly larger than the size of the eggs.

[0101] In the specific eggshell detection process, when the poultry eggs are sent to the sorting inner cylinder 42, they are pressed and contacted with the convex head 511 in sequence through the hydraulic transmission component 7, and the sorting inner cylinder 42 slides up and down. Due to the up and down movement, the poultry eggs in the sorting inner cylinder 42 can smoothly slide from the upper and lower sorting inner cylinders 42, and the entire poultry eggs can continuously adjust their positions and angles in the sorting inner cylinder 42. During the sliding process, the eggs are irradiated from multiple directions by the lighting searchlight 10 at the bottom, and the irradiation situation is fed back in real time through an external sensor, so that the detection results of the poultry eggs can be obtained quickly and accurately. This avoids the relative position of the poultry eggs irradiated by the traditional lighting searchlight 10 being too single and fixed, which leads to the result of the detection after irradiation being generalized and unconvincing.

[0102] Further, the hydraulic transmission assembly 7 includes:

[0103] A connecting pipe is arranged on the side wall of the tube opening of the sorting sleeve 4, and piston rods 71 ​​are respectively connected to the two ends of the connecting pipe in a sealing and sliding manner;

[0104] One of the piston rods 71 ​​is connected to the sorting inner cylinder 42 , and the other piston rod 71 is located below the fixing ring 51 and can at least contact the protrusion 511 .

[0105] In the present invention, the entire hydraulic transmission assembly 7 includes a completely unobstructed connecting pipe 72, which is filled with gas to make it have pressure. At both ends of the connecting pipe 72, movable piston rods 71 ​​are respectively arranged, and the rod head of one piston rod 71 is arranged directly opposite to the fixing ring 51, and the other piston rod 71 is connected to the sorting inner cylinder 42. Therefore, during the rotation of the sorting platform 5, one of the piston rods 71 ​​is constantly pressed and contacted with the convex head 511, and the piston rod 71 at the other end will move up and down, thereby being able to drive the sorting inner cylinder 42 to slide up and down relative to the sorting sleeve 4, so that the poultry eggs can slide smoothly from the barrel mouth of the sorting inner cylinder 42 to the bottom, so that the poultry eggs can slide irregularly in the sorting inner cylinder 42, and then the lighting searchlight 10 can illuminate different positions of the poultry eggs, ensuring the adequacy and accuracy of the lighting detection.

[0106] Furthermore, a plurality of buffer brush heads 9 are arranged in an array around the inner wall of the sorting inner cylinder 42 .

[0107] In the present invention, a plurality of buffer brush heads 9 surrounding the array inside the sorting inner cylinder 42 are made of soft rubber material. Among them, the plurality of buffer brush heads 9 in the sorting inner cylinder 42 extend vertically from the inner wall of the sorting inner cylinder 42 to the central axis direction of the cylinder, and the channel formed in the middle is smaller than the volume of the eggs. After the eggs are placed in the sorting inner cylinder 42, the piston rod 71 in the hydraulic transmission assembly 7 makes the sorting inner cylinder 42 slide up and down in cooperation with the convex head 511, and under the effect of the self-weight of the eggs, the eggs can have a buffered downward fall to the bottom of the sorting inner cylinder 42, thereby continuously changing the relative position of the lighting searchlight 10 irradiating the eggs, so that the lighting detection result is more sufficient and effective. At the same time, this action can also clean the surface of the eggs.

[0108] Furthermore, the sorting inner cylinder 42 includes two half sorting inner cylinders 421, and the buffer brush heads 9 in the two half sorting inner cylinders 421 are staggered in the vertical direction.

[0109] In the present invention, the above-mentioned sorting inner cylinder 42 is divided into two halves to form two half sorting inner cylinders 421. The buffer brush heads 9 located at the same layer in one half sorting inner cylinder 421 have a height difference relative to the buffer brush heads 9 at the same layer in the other half sorting inner cylinder 421, and the overall arrangement of the entire buffer brush heads 9 in the two half sorting inner cylinders 421 is staggered up and down. When the eggs are sent into the sorting inner cylinder 42, since the two half sorting inner cylinders 421 are connected to the hydraulic transmission components 7, the piston rods 71 ​​in the respective hydraulic transmission components 7 alternately squeeze the convex heads 511, so that each piston rod 71 correspondingly squeezes the respective half sorting inner cylinders 421, so that it slides up and down alternately in the sorting sleeve 4, thereby utilizing the asynchronism of the two sorting sleeves 4 moving up and down, so that the eggs can roll and slide down more smoothly, and then the illumination searchlight 10 can be used to continuously irradiate and detect different positions of the eggs, so that the detection operation can be fully realized to ensure the accuracy of the data after the detection.

[0110] Furthermore, a hydraulic transmission assembly 7 is provided between each half-sorting inner cylinder 421 and the fixed ring 51, and the piston rod 71 is orthographically projected onto the fixed ring 51, and a first arc angle corresponding to one piston rod 71 and its adjacent convex head 511 is greater than or less than a second arc angle corresponding to another piston rod 71 and its adjacent convex head 511;

[0111] Preferably, the first arc angle differs from the second arc angle by at least an arc angle corresponding to the protrusion 511 .

[0112] In the present invention, the hydraulic transmission assembly 7 is arranged on each semi-sorting inner cylinder 421, and the rod heads of the piston rods 71 ​​of the two hydraulic transmission assemblies 7 are directly opposite to the lower side of the fixing ring 51, and the upward extension of the piston rod 71 can fall on the path of the convex head 511. It should be noted that the first arc angle corresponding to the corresponding piston rod 71 relative to the adjacent convex head 511 is different from the second arc angle corresponding to the other piston rod 71 relative to the adjacent convex head 511. By limiting the arc angle, it can be ensured that when the piston rod 71 squeezes the convex head 511, the two piston rods 71 ​​will not be squeezed at the same time and press down the corresponding semi-sorting inner cylinder 421, so that the two semi-sorting inner cylinders 421 can have an alternating up and down movement, and then it can be ensured that the poultry eggs can smoothly roll and slide in the sorting inner cylinder 42, and the irradiation position of the lighting searchlight 10 relative to the poultry eggs is constantly changed.

[0113] Furthermore, by limiting the arc angle corresponding to the convex head 511, the alternating action of the semi-sorting inner cylinder 421 can be fully controlled to ensure the maximum relative movement amplitude and avoid the situation where both move downward at the same time or move downward at a certain time point during the downward movement.

[0114] Furthermore, it also includes:

[0115] The top cover 1201 is rotatably disposed above the sorting inner cylinder 42 and can be used to block the cylinder mouth of the sorting inner cylinder 42;

[0116] The bottom cover 1202 is disposed at the bottom of the sorting sleeve 4 .

[0117] In the present invention, a top cover 1201 is rotatably provided above the sorting inner cylinder 42, and a bottom cover 1202 is provided at the bottom of the sorting sleeve 4. The above-mentioned illumination searchlight 10 can be provided at the bottom of the sorting sleeve 4 or on the bottom cover 1202, preferably at the bottom of the sorting sleeve 4. The top cover 1201 can seal the poultry eggs inside to prevent them from falling off during the sliding process of the sorting inner cylinder 42.

[0118] Furthermore, a transmission part is provided between the top cover 1201 and the bottom cover 1202, so that when the top cover 1201 rotates to block the sorting inner cylinder 42, the bottom cover 1202 moves up to block the bottom of the sorting sleeve 4;

[0119] The transmission part includes a transmission rope 1101 , one end of which is connected to the rotating shaft of the top cover 1201 , and the other end of which is connected to the bottom cover 1202 .

[0120] In the present invention, the transmission rope 1101 arranged between the top cover 1201 and the bottom cover 1202 is connected to the outer wall of the rotating shaft. When the top cover 1201 rotates to close the sorting inner cylinder 42, the transmission rope 1101 is wound and tightened as a whole, so that the bottom cover 1202 below can be pulled upward. By controlling the length of the transmission rope 1101, when the top cover 1201 closes the mouth of the sorting inner cylinder 42, the bottom cover 1202 just closes the bottom of the sorting sleeve 4, so that a completely closed chamber is formed in the entire sorting inner cylinder 42, that is, it will not be affected by external light. It can ensure that the irradiation of the eggs is completely derived from the light of the illumination searchlight 10, and the accuracy of the irradiation detection is guaranteed.

[0121] Furthermore, it also includes a driving mechanism, which is arranged on the side wall of the barrel mouth of the sorting sleeve 4, and the driving end of the driving mechanism is connected to the rotating shaft of the top cover 1201.

[0122] In the present invention, the driving mechanism arranged on the side wall of the sorting sleeve 4 includes at least a driving motor 11, and the driving end of the driving motor 11 is fixedly connected to the rotating shaft of the top cover 1201, so that the driving motor 11 can be used to realize the rotation of the top cover 1201, and then the sealing of the sorting inner cylinder 42 can be timely controlled.

[0123] Furthermore, a plurality of vertically slidable connection structures 6 are evenly spaced on the outer peripheral wall of the sorting platform 5, and the connection structure 6 at least includes a connection portion 63 extending along the radial direction of the sorting platform 5; each sorting sleeve 4 is slidably connected to each connection portion 63;

[0124] The trigger portion 62 has at least one inclined surface 621, which extends outward and downward gradually from the axis of the sorting platform 5. When eggs are placed, the sorting sleeve 4 drives the connecting structure 6 to slide downward and is squeezed by the inclined surface 621 to gradually move away from the axis of the sorting platform 5.

[0125] In the present invention, the connection structure 6 can slide vertically relative to the height direction of the sorting platform 5, and the connection structure 6 is provided with a connection portion 63 extending horizontally along the radial direction of the sorting platform 5. A sorting sleeve 4 is also included, which is sleeved on the connection portion 63 and can slide along the extension direction of the connection portion 63. A trigger portion 62 corresponding to the connection portion 63 in each connection structure 6 is also provided on the sorting platform 5, and the trigger portion 62 includes an inclined surface 621. When eggs are placed in the sorting sleeve 4, the connection portion 63 slides vertically relative to the sorting platform 5 under the action of gravity, so that it contacts and presses with the inclined surface 621 during the sliding process, so that the sorting sleeve 4 moves along the extension direction of the connection portion 63 in a direction away from the axis of the sorting platform 5, so that the entire sorting sleeve 4 moves downwardly relative to the sorting platform 5.

[0126] According to the different weights of the eggs in the sorting sleeve 4, the overall distance from the sorting platform 5 is different. With the different conveying tracks 21 on the conveyor belt 2, the automatic sorting operation can be easily performed according to the weight of the eggs. Since the entire sorting platform 5 can rotate, it can cooperate to achieve continuous sorting action, and can be manually picked up or automatically put down from the bottom of the sorting sleeve 4, and the entire sorting action saves time and effort.

[0127] At the same time, the cracks of the eggs can be automatically detected before sorting, and then the eggs can be sorted according to their weight in different conveying tracks 21, thereby realizing a multi-faceted screening action for cracks and quality of the entire egg.

[0128] The present invention also provides an incubation device having a poultry egg crack detection structure of any of the above-mentioned embodiments. An incubation device is arranged at the conveying end of the conveying track 21, and the operator can carry out the final incubation operation on the sorted and inspected poultry eggs, thereby realizing overall automated processing and improving the overall hatching efficiency.
