Description

Technical Field

[0001] The invention belongs to the technical field of silkworm screening, and in particular relates to an automatic silkworm sorting device and a sorting method. Background Art

[0002] When sorting white silkworms, traditional sorting relies on manual labor, which is inefficient, labor-intensive, and has inconsistent sorting standards. It is difficult to meet large-scale production needs, and the sustainability of manual sorting faces challenges.

[0003] The patent with application number CN202310894179.9 discloses an intelligent sorting equipment for cocoon processing, including: an operating table, the top of the operating table is rotatably connected to a frustum, the top of the frustum has light tubes in a circular array, the top of the light tubes are placed with a box body, and one end of the box body is rotatably connected to the top of the frustum. The above scheme is provided with a lamp tube, a box body, a driving mechanism, a visual sensor and a discharge hopper. The lamp tube illuminates the cocoons in the box body, so that the visual sensor can detect whether there are double silkworm pupae in the cocoon with the assistance of the light, and can check the color of the cocoon when the lamp tube is not on, and make a corresponding judgment by comparing the reference stored in the controller. When the detected cocoons rotate to the corresponding discharge hopper, the driving mechanism can be started to discharge the cocoons in the box body, so that the cocoons can be inspected and classified intelligently and automatically without using a large amount of manpower, which is beneficial to improving the production efficiency of silk products. Although the above scheme realizes the sorting of cocoons, the impurities in the cocoons are not cleaned during the sorting process, which affects the quality after sorting.

[0004] During the automatic sorting of silkworm pupae, there are many impurities in the silkworm pupae, which affect the sorting efficiency and damage the integrity of the silkworm pupae. At the same time, during the sorting of impurities and silkworm pupae, it is impossible to sort the impurities and unqualified silkworm pupae at one time, which affects the sorting efficiency and sorting quality of the silkworm pupae.

[0005] Therefore, in order to solve the above technical problems, the present invention proposes an automatic sorting device and a sorting method for white silkworms. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems. The present invention provides an automatic sorting device and a sorting method for white silkworms, which have the advantages of rapid impurity removal and sorting.

[0007] To achieve the above object, the present invention provides the following technical solution: an automatic sorting device for white silkworms, comprising a support assembly, a feeding assembly is connected to the support assembly, a sorting assembly is connected to one end of the feeding assembly, a discharging assembly is connected to one end of the sorting assembly away from the feeding assembly, and a conveying assembly for moving the sorted silkworms is connected to the outer periphery of the sorting assembly; The sorting assembly comprises a sleeve, a sorting cavity is formed in the sleeve, and a plurality of primary holes, intermediate holes and advanced holes are formed in the sleeve, wherein the primary holes are located on a side of the sleeve close to the feeding assembly, and the advanced holes are located on a side of the sleeve far from the feeding assembly; A plurality of elastic components are connected in the sorting cavity, and the plurality of elastic components are evenly connected between the primary hole and the intermediate hole in a ring shape.

[0008] Preferably, the elastic component includes a supporting plate, one end of which is rotatably connected to the cavity wall of the sorting cavity, one end of the supporting plate close to the primary hole is connected to an elastic rod, and one end of the elastic rod away from the supporting plate is connected to a movable plate.

[0009] Preferably, the conveying component includes a connecting box, a conveying cavity is provided through the connecting box, the conveying cavity is divided into three chambers, the three chambers correspond to the positions of the primary hole, the intermediate hole and the high-level hole respectively, and three conveying ports corresponding to the three chambers are opened at one end of the conveying cavity away from the sorting component.

[0010] Preferably, the feed component comprises a feed cavity, one end of the feed cavity close to the sorting component is connected to a feed port, and a screening plate is movably provided on the cavity wall of the feed cavity.

[0011] Preferably, the discharging assembly comprises a discharging cavity, the position of the discharging cavity corresponds to the position of the sorting cavity, and one end of the discharging cavity away from the sorting cavity is connected to a discharging port.

[0012] Preferably, a power component for rotating the sorting component is connected to the outer circumference of the sleeve.

[0013] Preferably, a through hole is formed through the cavity wall of the delivery cavity.

[0014] Preferably, a connecting plate is movably provided in the conveying cavity, and the connecting plate is located on a side of the through hole close to the sorting component.

[0015] A sorting method using an automatic sorting device for white silkworms comprises the following steps: S1. Put the silkworms to be sorted into the feeding chamber, and make them move and contact with the screening plate, so as to slow down the silkworms and simply separate the impurities inside them; S2, the silkworms after passing through the screening plate enter the sorting chamber through the feed port, and the silkworms in the sorting chamber are sorted by rotating the sleeve; S3, the silkworms of different sizes pass through the primary hole, the intermediate hole and the advanced hole in turn, so as to achieve the sorting of silkworms of different sizes; S4. When the number of impurities passing through the intermediate holes is large, the elastic component is controlled to expand, the moving speed of the silkworms in the sorting chamber is suppressed, and the residence time of the silkworms in the primary holes is increased; S5, the sorted silkworms enter the conveying cavity, and the silkworms in the conveying cavity are sorted for the second time through the action of the connecting plate, and the qualified silkworms pass through the through holes and enter the conveying port.

[0016] S6. The silkworms that have not passed through the advanced holes pass through the sorting cavity and enter the discharging assembly, and are stored in the discharging cavity and the discharging port in turn.

In the sorting process, the sorting situation of the silkworms in the sorting components can be judged according to the impurity situation in the conveying components. That is, when the number of impurities entering the intermediate holes increases, the elastic components are used to increase the residence time of the silkworms in the primary hole area to ensure that the silkworms can be fully sorted and improve the sorting quality of the silkworms.

[0018] Through the coordinated action of the screening plate, sorting components, elastic components and connecting plates, the silkworms are sorted according to their volumes, while reducing the interference and influence of impurities during the sorting process. When silkworms of the same volume pass through the connecting plate, the silkworms with low weight are sorted and filtered, thereby improving the sorting efficiency and quality of the silkworms after sorting.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1

[0023] like Figure 1-Figure 8 As shown, an automatic sorting device for white silkworms comprises a supporting component 1, wherein the supporting component 1 is composed of a metal frame for supporting the sorting device, a feeding component 2 for silkworms to enter is connected to the supporting component 1, one end of the feeding component 2 is connected to a sorting component 4 for classifying the sizes of the silkworms, one end of the sorting component 4 away from the feeding component 2 is connected to a discharging component 6 for discharging the silkworms that have not passed through the sorting component 4, and the outer periphery of the sorting component 4 is connected to a conveying component 5 for moving the sorted silkworms. When in use, the unsorted silkworms are placed in the feeding component 2, so that the silkworms enter the sorting component 4 through the feeding component 2, thereby classifying silkworms of different sizes through the rotation of the sorting component 4, prompting the sorted silkworms to enter the conveying component 5 for classification and storage, and at the same time, the silkworms that have not passed through the sorting component 4 enter the conveying component 5 for transportation and storage after passing through the sorting component 4.

[0024] It should be noted that in order to ensure that the silkworms can move in the sorting component 4, when the sorting component 4 is connected to the supporting component 1, the sorting component 4 is tilted, that is, the height of the side of the sorting component 4 close to the feeding component 2 is high, and the height of the side close to the conveying component 5 is low, to ensure that after the silkworms enter the sorting component 4, they can move to the side close to the conveying component 5 under the action of gravity.

[0025] In order to facilitate the separation of silkworms of different sizes and reduce the interference of impurities on silkworms, the sorting component 4 includes a sleeve 401, which is rotatably connected to the support component 1. A sorting cavity 402 is opened in the sleeve 401, and one end of the sorting cavity 402 is connected to one end of the feed component 2, and the other end is connected to the discharge component 6. The sleeve 401 is evenly divided into three areas, and a plurality of primary holes 4011, intermediate holes 4012 and advanced holes 4013 are respectively opened in the three areas. That is, the distribution order between the feed component 2 and the discharge component 6 is primary hole 4011, intermediate hole 4012 and advanced hole 4013, wherein the primary hole 4011 is located on the side close to the feed component 2 on the sleeve 401, and the advanced hole 4013 is located on the side away from the feed component 2 on the sleeve 401. At the same time, the aperture of the primary hole 4011 is smaller than the aperture of the intermediate hole 4012, and the aperture of the intermediate hole 4012 is smaller than the aperture of the advanced hole 4013, thereby realizing the sorting of silkworms of different sizes.

[0026] It should be noted that, in order to prevent the silkworms from being damaged during the sorting process in the sorting chamber 402, the cavity wall of the sorting chamber 402 is set to be a flexible material, thereby ensuring the integrity of the silkworms.

[0027] In order to ensure that impurities in the silkworm pupae and silkworm pupae with smaller size can be fully removed in the primary hole 4011, a plurality of elastic components 7 for adjusting the position of the silkworm pupae are connected in the sorting chamber 402. The plurality of elastic components 7 are evenly connected in a ring shape between the primary hole 4011 and the intermediate hole 4012. There is a gap between two adjacent elastic components 7 to prevent the silkworm pupae from accumulating in the primary hole 4011. The deflection angle of the elastic component 7 is adjusted according to the type of silkworm pupae entering the intermediate hole 4012, so as to increase the residence time of the silkworm pupae in the area of ​​the primary hole 4011, thereby achieving sufficient removal of silkworm pupae and impurities with smaller size, and ensuring that the probability of the silkworm pupae entering the conveying component 5 being affected by impurities is reduced.

[0028] Furthermore, in order to ensure that the silkworms are fully sorted in the area of ​​the primary hole 4011 and reduce the impact of subsequent impurities, the elastic component 7 includes a supporting plate 701 for angle adjustment, one end of the supporting plate 701 is rotatably connected to the cavity wall of the sorting cavity 402, so that the angle of the elastic component 7 can be controlled according to the sorting situation of the intermediate hole 4012, and an elastic rod 702 is connected to the end of the supporting plate 701 close to the primary hole 4011, and a movable plate 703 is connected to the end of the elastic rod 702 away from the supporting plate 701. During the rotation and sorting process of the sorting component 4, the silkworms can contact the movable plate 703 after passing through the position of the primary hole 4011, and under the elastic action of the elastic rod 702, the movable plate 703 is prompted to bounce the silkworms back to the area of ​​the primary hole 4011 for secondary filtration, thereby ensuring that the silkworms and the impurities carried on the silkworms are fully sorted in the primary hole 4011.

[0029] When the number of impurities entering the intermediate hole 4012 is at a normal number, the angle of the control plate 701 is reduced, so that the support plate 701 is close to the cavity wall of the sorting cavity 402, reducing the rebound of the movable plate 703 on the silkworm, and improving the sorting efficiency of the silkworm. When the number of impurities entering the intermediate hole 4012 is higher than the normal number, the angle of the control plate 701 is increased, so that the support plate 701 and the cavity wall of the sorting cavity 402 tend to be vertical, increasing the contact area between the silkworm and the movable plate 703, and ensuring that the silkworm is completely sorted at the primary hole 4011.

[0030] In order to ensure that the silkworm can smoothly return to the position of the primary hole 4011 after the elastic action of the movable plate 703, when the movable plate 703 is connected to the elastic rod 702, there is an angle between the movable plate 703 and the supporting plate 701, and the end away from the connection between the supporting plate 701 and the sorting chamber 402 is the farthest from the supporting plate 701.

[0031] Furthermore, in order to transport the sorted silkworms to the target position, the conveying component 5 includes a connecting box 502, which is fixedly connected to the supporting component 1, and is located on one side of the sorting component 4 close to the ground support. A conveying chamber 501 is provided in the connecting box 502, and the end of the conveying chamber 501 close to the sorting component 4 is a through opening, which can prompt the silkworms passing through the sorting component 4 to enter the conveying chamber 501. In order to facilitate the classification, transportation and storage of silkworms of different types, the conveying chamber 501 is divided into three chambers, which are separated by partitions, and the three chambers correspond to the positions of the primary hole 4011, the intermediate hole 4012 and the advanced hole 4013, respectively. The end of the conveying chamber 501 away from the sorting component 4 is provided with three conveying openings 503 corresponding to the three chambers, and the conveying openings 503 are used to classify and output the silkworms in different chambers for easy collection and storage.

[0032] Furthermore, in order to reduce the amount of impurities entering the sorting component 4, the feed component 2 includes a feed chamber 201, and one end of the feed chamber 201 close to the sorting component 4 is connected to a feed port 203, and the silkworms to be sorted enter the feed chamber 201, and are discharged from the feed chamber 201 through the feed port 203 and enter the sorting component 4, and a screening plate 202 is movably provided on the cavity wall of the feed chamber 201, that is, the edge of the screening plate 202 is connected to the cavity wall of the feed chamber 201, and the screening plate 202 Located on the side of the feed chamber 201 close to the ground, after the silkworms enter the feed chamber 201, the screen plate 202 is driven to vibrate under the action of gravity, and the impurities in the silkworms are preliminarily separated from the silkworms, that is, the impurities with smaller volume are directly moved out of the feed chamber 201 through the screen plate 202. At the same time, the screen plate 202 is used to reduce the potential energy of the silkworms, ensuring that the movement speed of the silkworms entering the sorting component 4 is stable, so that the sorting component 4 can be used to fully sort the silkworms.

[0033] Furthermore, in order to output the silkworms that have not passed through the high-level holes 4013 from the sorting chamber 402, the discharge component 6 includes a discharge chamber 601, and the discharge chamber 601 corresponds to the position of the sorting chamber 402. The end of the discharge chamber 601 away from the sorting chamber 402 is connected to a discharge port 602. The silkworms coming out of the sorting chamber 402 directly enter the discharge chamber 601, and the unsorted silkworms are collected and stored through the discharge port 602.

[0034] Furthermore, a power component 3 for rotating the sorting component 4 is connected to the outer circumference of the sleeve 401, wherein the power component 3 includes a servo motor, a gear set, and a gear connected to the outer circumference of the sleeve 401, and then the sleeve 401 is driven to rotate by the power component 3, ensuring that the silkworms can move in the sorting chamber 402, thereby realizing the sorting of silkworms of different volumes.

[0035] Furthermore, since some impurities can enter the conveying chamber 501 through the sorting chamber 402, affecting the sorting quality of the silkworms, a through hole 5011 is opened through the wall of the conveying chamber 501. Since the weight of the silkworms is greater than the weight of the impurities, after the silkworms enter the conveying chamber 501, the silkworms are affected by the gravitational potential energy and their movement speed is greater than the movement speed of the impurities. Therefore, the silkworms can enter the conveying port 503 through the through hole 5011. At the same time, impurities with a slower movement speed pass through the through hole 5011 and fall out of the conveying component 5, thereby realizing secondary sorting of the silkworm impurities.

[0036] Furthermore, in order to prevent the silkworm from being affected by gravity, the parabola formed by the moving path cannot pass through the through hole 5011, and a connecting plate 8 is movably provided in the conveying chamber 501. There is an angle between the connecting plate 8 and the cavity wall of the conveying chamber 501, and the connecting plate 8 is located on the side of the through hole 5011 close to the sorting component 4. Then, when the silkworm enters the conveying chamber 501, the silkworm is prompted to rush out of the connecting plate 8 under the influence of gravitational potential energy, so that the landing point of the parabola is located on the side close to the conveying port 503, and the lighter impurities are blocked by the connecting plate 8, and some impurities are discharged through the through hole 5011, thereby ensuring the sorting efficiency of the silkworm.

[0037] It should be noted that when connecting the connecting plate 8, a spring can be arranged to be connected to one side of the connecting plate 8 close to the through hole 5011, so that when the silkworms pass through the connecting plate 8, the spring on the connecting plate 8 can be compressed, and when the silkworms are about to leave the connecting plate 8, elastic force is provided to the silkworms, ensuring that the silkworms can stably pass through the through hole 5011, thereby improving the sorting efficiency of the silkworms, and in this process, when the lighter silkworms or impurities contact the connecting plate 8, the spring on the connecting plate 8 will not be compressed, that is, the lighter silkworms or impurities cannot pass through the through hole 5011.

[0038] When in use, first control the power component 3 to work, drive the sleeve 401 to rotate, put the silkworms to be sorted into the feeding component 2, so that the silkworms enter the feeding chamber 201, and under the action of the gravity of the silkworms, the silkworms drive the screening plate 202 to vibrate, and the impurities in the feeding chamber 201 are initially separated. At the same time, the descending rate of the silkworms is buffered to avoid damage to the silkworms and suppress the initial velocity of the silkworms entering the sorting component 4. After screening by the screening plate 202, the silkworms enter the sorting chamber 402 through the feeding port 203.

[0039] After the silkworms enter the sorting chamber 402, the rotation of the sleeve 401 causes the silkworms to move relative to the wall of the sorting chamber 402, so that impurities with smaller volume and not screened by the screening plate 202 enter the conveying chamber 501 through the primary hole 4011. At the same time, since the sleeve 401 is placed at an angle, the unsorted silkworms pass through the intermediate hole 4012 and the high-level hole 4013 in turn to enter the conveying chamber 501, and then the silkworms move in the conveying chamber 501 under the action of gravity, causing the silkworms to pass through the connecting plate 8, and pass through the through hole 5011 and then pass through the conveying port 503, thereby realizing the classified storage of silkworms of different volumes, and the silkworms that do not pass through the high-level hole 4013 are transferred to the discharge assembly 6, so that they enter the discharge chamber 601 and are stored through the discharge port 602.

[0040] At the same time, in the process of transporting the silkworms in the transport chamber 501 by using the connecting plate 8, on the one hand, impurities in the silkworms are removed, and on the other hand, silkworms with qualified volume but unqualified weight can be filtered, thereby improving the quality of the silkworms after sorting.

[0041] When there are many impurities dropped from the through hole 5011 corresponding to the intermediate hole 4012, it means that the moving speed of the silkworm in the sorting chamber 402 is too fast, and the impurities and silkworm cannot be sorted. Then, the elastic component 7 is controlled to rotate, so that an angle is formed between the supporting plate 701 and the cavity wall of the sorting chamber 402, and the movable plate 703 is located on the side close to the primary hole 4011, so that when the silkworm moves in the sorting chamber 402, the silkworm first collides with the movable plate 703, and under the action of the elastic rod 702, the silkworm in contact with the surface of the movable plate 703 is bounced back to the side close to the feeding component 2, so as to slow down the moving speed of the impurities and silkworm in the sorting chamber 402, increase the residence time of the silkworm at the primary hole 4011, prompt the silkworm and impurities to be fully sorted at the primary hole 4011, and improve the subsequent sorting quality of the silkworm.

[0042] Then, through the joint action of the screening plate 202, the sorting component 4, the elastic component 7 and the connecting plate 8, the silkworms are sorted according to their volumes, while reducing the interference and influence of impurities during the sorting process, thereby improving the sorting efficiency and quality of the silkworms after sorting.

[0043] Embodiment 2

[0044] The present invention also includes a sorting method using the automatic sorting device for white silkworms, comprising the following steps: S1, placing the silkworms to be sorted into the feed chamber 201, prompting the silkworms to move and contact the screening plate 202, thereby decelerating the silkworms and simply separating the impurities inside them; S2, the silkworms after passing through the screening plate 202 enter the sorting chamber 402 through the feed port 203, and the silkworms in the sorting chamber 402 are sorted by rotating the sleeve 401; S3, the silkworms of different sizes pass through the primary hole 4011, the intermediate hole 4012 and the advanced hole 4013 in sequence, so as to achieve the sorting of silkworms of different sizes; S4, when the number of impurities passing through the intermediate hole 4012 is large, the elastic component 7 is controlled to expand, the moving speed of the silkworms in the sorting cavity 402 is suppressed, and the residence time of the silkworms in the primary hole 4011 is increased; S5, the sorted silkworms enter the conveying chamber 501, and the silkworms in the conveying chamber 501 are sorted for the second time by the action of the connecting plate 8, and the qualified silkworms pass through the through hole 5011 and enter the conveying port 503.

[0045] S6. The silkworms that have not passed through the high-level hole 4013 pass through the sorting chamber 402 and enter the discharging assembly 6, and are stored in the discharging chamber 601 and the discharging port 602 in sequence.
