[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As in the background art, since the trays of the breeding rack set in this patent are arranged vertically, it is difficult to take out the silkworms in the trays located near the top. At the same time, when feeding the silkworms, mulberry leaves need to be scattered and laid flat on the top of the trays. Therefore, the arrangement of multiple trays in a vertical direction is not conducive to feeding the silkworms in the trays located in the middle and the inner side of the trays located at the top, which will increase the labor intensity of breeding.

[0030] To address this technical problem, this utility model provides a breeding rack. By arranging multiple trays in a circular motion, it avoids the need for users to climb to operate the uppermost tray, thereby improving the convenience of the breeding rack. At the same time, by collecting and feeding mulberry leaves in a unified manner, it saves space for storing mulberry leaves and raising silkworms, and also reduces the workload of users in feeding silkworms, thus further enhancing the convenience of the breeding rack.

[0031] For details, please refer to Figures 1-2 A type of breeding rack specifically includes a first base plate 1, a feeding component 2 is provided on the top of the first base plate 1 and one end of the first base plate 1, and a feed adjustment component 3 is provided inside the feeding component 2;

[0032] The feeding assembly 2 includes a first motor 4, a first screw 5, and a first movable block 6. A first movable groove is provided at one end of the top of the first base plate 1. The first motor 4 is fixedly connected to one end of the inner side of the first movable groove, and the first motor 4 is located at the center position away from the first base plate 1. The output end of the first motor 4 is fixedly connected to the first screw 5.

The first movable block 6 is threadedly connected to the outer side of the first screw 5, and the first movable block 6 is clearance-fitted to the inner side of the first movable groove.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] Please refer to Figure 1 A type of breeding rack includes a first base plate 1, a feeding component 2 is provided on the top of the first base plate 1 and at one end of the first base plate 1, and a feed adjustment component 3 is provided inside the feeding component 2.

[0036] By setting up the feeding component 2, silkworms can be placed in batches. The arrangement of the silkworms surrounding the inner side of the feeding component 2 reduces the workload of staff in feeding and managing silkworms, thereby improving the convenience of silkworm farming.

[0037] It also allows for centralized storage of mulberry leaves, saving space for storing mulberry leaves and raising silkworms, while reducing the workload of users in feeding silkworms, thus further improving the convenience of the breeding rack.

[0038] By setting the feed adjustment component 3, the amount of mulberry leaves can be controlled when feeding silkworms, thereby adapting the amount of mulberry leaves to the growth rate of the silkworms and improving the breeding effect.

[0039] Example 2:

[0040] This embodiment 2 further discloses the specific structure of the feeding component 2 based on the above embodiments. By cooperating with the structure in the above embodiments, the feeding component 2 can be set up to move multiple trays around, thereby avoiding the need for the user to climb to operate the uppermost tray, thus improving the convenience of the breeding rack. At the same time, by collecting and feeding mulberry leaves in a unified manner, the space for placing mulberry leaves and raising silkworms can be saved, and the workload of the user in feeding silkworms can be reduced, thereby further improving the convenience of the breeding rack.

[0041] The breeding rack provided in Example 1 has been further optimized, specifically, as follows: Figures 2-5 As shown, the feeding assembly 2 includes a first motor 4, a first screw 5, and a first movable block 6. A first movable groove is provided at one end of the top of the first base plate 1. The first motor 4 is fixedly connected to one end of the inner side of the first movable groove, and the first motor 4 is located at the center position away from the first base plate 1. The output end of the first motor 4 is fixedly connected to the first screw 5. The end of the first screw 5 away from the first motor 4 is rotatably connected to the inner side of the first movable groove. The first movable block 6 is threadedly connected to the outer side of the first screw 5, and the first movable block 6 is clearance-fitted to the inner side of the first movable groove.

[0042] The feeding assembly 2 also includes a second base plate 7, a support vertical plate 8, a turntable 9, a first transmission belt 10, and a second motor 11. The top of the first movable block 6 is fixedly connected to the second base plate 7. The top two sides of the top of the second base plate 7 are fixedly connected to the support vertical plates 8. The top and bottom of the two support vertical plates 8 that are close to each other are rotatably connected to the turntable 9. The outer sides of the two turntables 9 on the same side are provided with the first transmission belt 10, and one of the turntables 9 drives the other turntable 9 to rotate through the first transmission belt 10. The side of one of the support vertical plates 8 away from the turntable 9 is fixedly connected to the second motor 11. The position of the second motor 11 corresponds to one of the turntables 9, and the output end of the second motor 11 passes through the support vertical plate 8 and is fixedly connected to the corresponding turntable 9.

[0043] The feeding assembly 2 also includes a feeding box 12, a counterweight 13, and a concave baffle 14. Multiple feeding boxes 12 are equidistantly arranged between the two first transmission belts 10, and both sides of the feeding box 12 are rotatably connected to the first transmission belt 10. The two ends of the bottom of the feeding box 12 are fixedly connected to the counterweight 13, and the top of the feeding box 12 is fixedly connected to the concave baffle 14.

[0044] The feeding assembly 2 also includes a feeding box 15, a second transmission belt 16, a shielding vertical plate 17, a third motor 18, and a guide plate 19. The feeding box 15 is fixedly connected to the end of the first base plate 1 away from the first movable groove. The second movable groove is opened on the side of the feeding box 15 near the first base plate 1. The second transmission belt 16 is fixedly connected to the inside of the feeding box 15. The two ends of the second transmission belt 16 are at different heights, and the higher end of the second transmission belt 16 extends to the top of the first base plate 1 through the second movable groove. The second transmission belt 16 and the concave baffle 14 are configured with a clearance fit. The shielding vertical plates 17 are fixedly connected to both sides of the second transmission belt 16 above the first base plate 1. The third motor 18 is fixedly connected to the side of the second transmission belt 16 inside the feeding box 15, and the third motor 18 drives the second transmission belt 16 to rotate. The guide plates 19 are fixedly connected to both sides of the inside of the feeding box 15. The guide plates 19 are located on both sides of the second transmission belt 16, and the top of the guide plates 19 near the second transmission belt 16 is inclined.

[0045] Specifically: Before raising silkworms, place them inside the bottommost placement box 12. Then turn on the second motor 11, which will drive one of the turntables 9 to rotate. At the same time, through the first transmission belt 10, the other turntable 9 on the same side will rotate. With the two turntables 9 supporting the first transmission belt 10, the first transmission belt 10 will move when the two turntables 9 rotate, thereby driving the placement box 12 connected to the outside of the first transmission belt 10 to move synchronously.

[0046] Meanwhile, the connection of the placement box 12 can drive the first transmission belt 10 on the other side to move synchronously. The arrangement of two first transmission belts 10 can improve the stability of the placement box 12 moving between the two support vertical plates 8, so that the placement box 12 without silkworms can be moved to the bottom, making it easier for staff to place the silkworms in batches.

[0047] By providing counterweights 13 at both ends of the bottom of the placement box 12, the placement box 12 can be kept in a horizontal position when the first transmission belt 10 moves the placement box 12, thereby preventing the placement box 12 from flipping over.

[0048] Before use, mulberry leaves can be placed inside the placement box 15. When it is necessary to feed the silkworms, the third motor 18 can be turned on and the second transmission belt 16 can be rotated. Through the limiting setting of the two guide plates 19, the mulberry leaves inside the placement box 15 can be guided to the top of the second transmission belt 16 and driven out of the placement box 15 by the second transmission belt 16.

[0049] Simultaneously, by turning on the first motor 4, the first screw 5 can be driven to rotate inside the first movable groove, thereby driving the first movable block 6, which is threadedly connected to the first screw 5, to move closer to the end of the placement box 15. This causes the second base plate 7, which is fixedly connected to the first movable block 6, to move synchronously. This causes the multiple placement boxes 12 above the second base plate 7 to move synchronously closer to the end of the placement box 15. At this time, the placement box 12 located at the bottom will move to be positioned below the higher end of the second transmission belt 16. At this time, the concave baffle 14 will have a wrapping effect on the second transmission belt 16.

[0050] Subsequently, the second transmission belt 16 transports the mulberry leaves to the top of the placement box 12. At the same time, the first motor 4 is turned on, which drives the first screw 5 to rotate in the opposite direction. This causes the second base plate 7 and the top placement box 12 to slowly move away from the placement box 15, thus achieving the effect of spreading the mulberry leaves flat on the top of the placement box 12, thereby improving the convenience of feeding silkworms.

[0051] All the motors mentioned above are motors with power-off self-locking capability, such as servo motors.

[0052] Example 3:

[0053] This embodiment 3 further discloses the specific structure of the feed adjustment component 3 based on the above embodiments. By cooperating with the structure in the above embodiments, the feed adjustment component 3 can intercept the top of the mulberry leaves during transportation to control the amount of mulberry leaves spread, thereby adaptively adjusting the amount of mulberry leaves fed according to the growth rate of the silkworms.

[0054] The breeding rack provided in Example 1 and Example 2 has been further optimized, specifically, as follows: Figures 6-7 As shown, the food quantity adjustment component 3 includes a fourth motor 20, a second screw 21, a first fixed rod 22, and a second movable block 23. A third movable slot is provided on one side of the two blocking vertical plates 17 that are close to each other. The top of one of the blocking vertical plates 17 is fixedly connected to the fourth motor 20, and the position of the fourth motor 20 corresponds to the third movable slot. The output end of the bottom of the fourth motor 20 extends to the inner side of the corresponding third movable slot and is fixedly connected to the second screw 21. The bottom of the second screw 21 is rotatably connected to the bottom of the inner side of the third movable slot. The inner side of the other third movable slot is fixedly connected to the first fixed rod 22. The inner side of each third movable slot is fitted with a second movable block 23 with clearance. One of the second movable blocks 23 is threadedly connected to the second screw 21, and the other second movable block 23 is slidably connected to the first fixed rod 22.

[0055] The food quantity adjustment component 3 also includes a movable horizontal plate 24, a second fixed rod 25 and a toggle rod 26. The movable horizontal plate 24 is fixedly connected to the side of the two second movable blocks 23 that are close to each other. Multiple second fixed rods 25 are fixedly connected between the two movable horizontal plates 24. Multiple toggle rods 26 are fixedly connected at equal intervals at the bottom of the second fixed rods 25.

[0056] Specifically: By setting the lever 26, when the second transmission belt 16 is conveying mulberry leaves, it can intercept the top of the mulberry leaves, thereby adjusting the amount of mulberry leaves fed by adjusting the thickness of the mulberry leaves.

[0057] By activating the fourth motor 20, the second screw 21 can be driven to rotate inside the third movable slot, thereby driving the second movable block 23, which is threadedly connected to the second screw 21, to move up and down inside the third movable slot. This, in turn, drives the movable horizontal plate 24, which is fixedly connected to the second movable block 23, to move synchronously. Through the connection of the second fixed rod 25, the movable horizontal plate 24 and the second movable block 23 on the other side can move synchronously inside another third movable slot. Through the sliding connection between the other second movable block 23 and the first fixed rod 22, the stability of the two movable horizontal plates 24 driving multiple second fixed rods 25 to move up and down between the two blocking vertical plates 17 can be improved.

[0058] By moving multiple second fixed rods 25 up and down through two movable horizontal plates 24, the bottom actuating rod 26 can be moved synchronously and the gap between the bottom of the actuating rod 26 and the top of the second transmission belt 16 can be adjusted. This allows the amount of mulberry leaves to be fed to the silkworms to be adjusted according to their growth rate, thereby further improving the convenience of silkworm farming.

[0059] All the motors mentioned above are motors with power-off self-locking capability, such as servo motors.
