Description

Technical Field

[0001] The present invention relates to the technical field of sericulture, and particularly to a device for automatically peeling cocoons and identifying male and female pupae suitable for sericulture production. Background Art

[0002] In sericulture production, cocoon peeling and identification of male and female pupae are key processes. Traditional methods rely on manual operation and have many drawbacks. On the one hand, manual cocoon peeling is inefficient and labor-intensive. Repeated operations for a long time are likely to cause fatigue, affecting the quality and speed of cocoon peeling. On the other hand, for the identification of male and female pupae, the manual method mainly relies on empirical observation, with limited accuracy, and there may be classification errors, affecting the efficiency of subsequent sericulture production processes and the quality of products.

[0003] After retrieval, a Chinese patent application with the application publication number CN221071731U discloses a device for peeling cocoons of silkworm pupae, including a cocoon peeling box. Under the influence of gravity, silkworm cocoons roll down along the upper surface of the primary screening conveyor belt, and cocoon floss fragments pass through the large sieve holes on the primary screening conveyor belt or move to the other side with the transportation to the primary screening conveyor belt and finally fall into the sewage tank located below the primary screening conveyor belt, improving the separation degree of cocoon floss fragments and silkworm cocoons, avoiding the contamination of silkworm cocoons falling into the clean water tank, and ensuring the cleanliness of silk.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figure 1-8 , a device for automatically peeling cocoons and identifying male and female pupae suitable for sericulture production, including a base 1, a feeding hopper 6 and a discharging plate 7. The top of the base 1 is set as an inclined plane. The discharging plate 7 is fixed above the top of the base 1. The feeding hopper 6 is fixedly connected above the top of the discharging plate 7. A cocoon peeling belt 8 is fixedly connected to the top of one side of the discharging plate 7. A baffle 4 is fixedly connected to the top of the other side of the discharging plate 7. A movable plate 22 is fixedly connected to the side of the baffle 4 close to the cocoon peeling belt 8. A slide rail 35 is fixedly connected to the side of the movable plate 22 close to the cocoon peeling belt 8. A vibration plate 25 is slidably connected to the side of the slide rail 35. A tooth groove 39 is opened at the top of the vibration plate 25. A second motor frame 32 is fixedly connected to the top of the movable plate 22. A vibration motor 23 is fixedly connected inside the second motor frame 32. The output end of the vibration motor 23 is drivingly connected with an incomplete gear 33. Half of the circumference of the outer wall of the incomplete gear 33 is provided with driving teeth. The driving teeth of the incomplete gear 33 are meshed and transmitted with the tooth groove 39. A sliding block 38 is fixedly connected to the middle of the bottom end of the vibration plate 25. A fixed block 37 is fixedly connected to the bottom end of the slide rail 35. The same return spring 34 is fixedly connected between the fixed block 37 and the sliding block 38. The bottom end of the discharging plate 7 is fixedly connected with a separation bin 9. The bottom end of the separation bin 9 is fixedly connected with a material guiding bin 11. The bottom end of the material guiding bin 11 is fixedly connected with an identification channel 12. An X-ray detector 13 is arranged at the top of the identification channel 12. The ray irradiation mechanism and the receiving mechanism of the X-ray detector 13 are located inside the identification channel 12. The X-ray detector 13 is connected to a controller through a signal line.

[0024] In use, cocoons are poured onto the discharge plate 7 through the feeding hopper 6. Under the guidance of the cocoon stripping belt 8 and the action of gravity, the cocoons flow between the cocoon stripping belt 8 and the vibrating plate 25. The vibrating motor 23 drives the incomplete gear 33 to rotate, and its transmission teeth mesh with the tooth grooves 39 of the vibrating plate 25, driving the vibrating plate 25 to move along the slide rail 35. The fixed block 37 and the sliding block 38 compress the return spring 34 during the movement of the vibrating plate 25. When the side of the incomplete gear 33 without transmission teeth moves close to the tooth groove 39, the return spring 34 pushes the vibrating plate 25 to reset through the sliding block 38. The vibrating motor 23 continuously outputs to achieve the purpose of vibrating the vibrating plate 25 at a fixed frequency, preventing the cocoons from clogging, ensuring the uniform distribution and gradual separation of the cocoons. The mechanical vibration of the vibrating plate 25 and the unidirectional traction of the cocoon stripping belt 8 are linked to form a composite vibration with a specific frequency and amplitude. Its vibration energy is transmitted to the cocoons in contact with it, exerting multi-directional and multi-frequency forces on the cocoons, eliminating the weak connections between some fibers on the surface of the cocoons, gradually opening the closed structure of the cocoons, and then separating the cocoons into pupae and cocoon shells. The separated cocoon shells and pupae fall into the separation bin 9. At the same time, some of the original impurities in the cocoons also enter the separation bin 9. After the impurities are separated by the separation bin 9, the cocoon shells and pupae enter the identification channel 12 through the guide bin 11. The inner width of the guide bin 11 gradually narrows towards the direction of the identification channel 12, which can guide the cocoon shells and pupae into the identification channel 12 one by one. The X-ray detector 13 emits rays to penetrate the objects in the identification channel 12 and receives the reflected signals. The controller generates images and analyzes the image data. First, the cocoon shells and pupae are distinguished according to the structural differences, and then the pupae are identified as male or female according to the presence or absence of silkworm eggs.

[0025] In the present invention, a bellows 14 is fixedly connected to the bottom end of the identification channel 12. One end of the base 1 close to the bellows 14 is fixedly connected to a bottom plate 15. One side of the bottom plate 15 is fixedly connected to a push rod frame 17. The top of the push rod frame 17 close to the bellows 14 is fixedly connected to an electric push rod 18. The telescopic end of the electric push rod 18 is fixedly connected to the outer wall of the bottom end of the bellows 14. The pupae and cocoon shells are discharged in sequence through the bottom pipe orifice of the bellows 14. The bellows 14 controls the orientation angle of the pipe orifice through the telescopic end of the electric push rod 18.

[0026] In the present invention, two material distribution grooves 16 are opened on the top of the bottom plate 15, and the two material distribution grooves 16 are respectively located on both sides of the two bellows 14. In use, containers for discharging materials are respectively placed inside the two material distribution grooves 16, and flexible buffer pads are laid inside both containers. The electric push rod 18 adjusts the angle of the bellows 14 according to the controller's instruction, so that the pupae with silkworm eggs fall into the container in one material distribution groove 16 alone, and the remaining pupae and cocoon shells fall into the container in the other material distribution groove 16.

[0027] In the present invention, the top of the base 1 is fixedly connected to a back frame 3, the top of the back frame 3 is fixedly connected to two side frames 2, a feeding plate 7 is fixedly connected to the tops of the two side frames 2, the top of the feeding plate 7 is fixedly connected to a top frame 5, and a loading hopper 6 is fixedly connected to the inside of the top frame 5.
