Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to a uniform feeding device for cultivating Chinese mitten crabs. Background Art
[0002] Chinese mitten crabs, also known as river crabs, hairy crabs, clear water crabs, and Eriocheir sinensis, are one of the traditional precious aquatic products in China. Chinese mitten crabs are rich in nutrition, containing protein, fat, and abundant vitamin A. In the early stage of the growth of crabs, they mainly feed on animal feed, which is beneficial to the absorption and molting growth of crab larvae.
[0003] When cultivating Chinese mitten crabs at present, the centralized feeding method is adopted for cultivation, that is, a large amount of feed is poured on one side of the pond, resulting in Chinese mitten crabs scrambling for food. Some Chinese mitten crabs cannot obtain enough feed, resulting in large growth differences among individual Chinese mitten crabs, which is not conducive to product sales. At the same time, when the feed accumulates together and cannot be consumed by Chinese mitten crabs in time, it will quickly deteriorate in high-temperature weather, which may cause Chinese mitten crabs to get sick or even die, causing economic losses. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a uniform feeding device for cultivating Chinese mitten crabs, which can solve the problem that when cultivating Chinese mitten crabs, the centralized feeding method is adopted, a large amount of feed accumulates on one side of the pond, resulting in Chinese mitten crabs scrambling for food, resulting in large growth differences among individual Chinese mitten crabs, which is not conducive to product sales.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0027] Please refer to Figures 1 to 7 , the present utility model provides a technical solution:
[0028] A uniform feeding device for hairy crab breeding, comprising a trolley 1. A feeding box 3 is fixedly connected to the top of the trolley 1. A stirring device is arranged in the inner cavity of the feeding box 3. The stirring device includes a rotating shaft 14. A control valve 29 is fixedly connected to the discharge port at the bottom of the inner cavity of the feeding box 3. The control valve 29 is used to open and close the discharge port. A feeding port 4 is opened at the top of the feeding box 3. Two groups of rollers 2 are respectively installed on both sides of the bottom of the trolley 1. A walking shaft 30 is fixedly connected between each group of rollers 2. A first gear 23 is fixedly connected to the outer surface of the left walking shaft 30. A second gear 24 is meshed with the outer edge of the first gear 23. A driving shaft 25 is fixedly connected to the top of the second gear 24. The top of the driving shaft 25 penetrates through the trolley 1 and a belt 8 is wound around the outer surface. An auxiliary roller 9 is movably connected to the inner cavity of the belt 8. A pushing block 10 is fixedly connected to the outer surface of the belt 8. A feeding device is arranged on one side of the pushing block 10. The feeding device includes a moving plate 11. One side of the moving plate 11 penetrates through the feeding box 3 and is fixedly connected to a baffle 22. The baffle 22 is slidably connected in the inner cavity of the feeding box 3. A control plate 21 is fixedly connected to the outer surface of the moving plate 11. A spring 12 is fixedly connected to the left side of the control plate 21. The other end of the spring 12 is fixedly connected to the inner cavity of the feeding box 3.
[0029] By adopting the above technical solution, after the operator puts the animal feed into the inner cavity of the feeding box 3 through the feeding port 4, the top and bottom of the inner cavity of the feeding box 3 are respectively a stirring area and a feeding area. After the feed is stirred and crushed by the stirring device, the operator opens the control valve 29 to make the feed enter the bottom feeding area. Then the operator pushes the trolley 1 to move in the breeding area, so that a group of rollers 2 installed at the left bottom of the trolley 1 drive the walking shaft 30 to rotate. The walking shaft 30 drives the first gear 23 on the outer surface to rotate. The first gear 23 drives the meshed second gear 24 to rotate. The second gear 24 drives the driving shaft 25 at the top to rotate. The driving shaft 25 drives the belt 8 on the outer surface to rotate. The belt 8 drives the auxiliary roller 9 in the inner cavity to rotate, so that the belt 8 drives the pushing block 10 to move synchronously. The pushing block 10 gradually approaches the moving plate 11 and contacts the moving plate 11, making the moving plate 11 move to the right. The moving plate 11 drives the control plate 21 to move synchronously. The control plate 21 gradually stretches the spring 12. At the same time, the moving plate 11 drives the baffle 22 to move, making the baffle 22 move to the right. The feed falls from the gap between the feeding box 3 and the baffle 22. When the pushing block 10 does not contact the moving plate 11, the spring 12 drives the moving plate 11, the control plate 21 and the baffle 22 to reset, making the baffle 22 block the bottom of the feeding box 3 again. The operator evenly distributes the feed in the breeding area by pushing the trolley 1, avoiding concentrating the feed in one place, thus ensuring that the hairy crabs can obtain sufficient food in each area and reducing the growth difference of the hairy crabs caused by uneven feed distribution.
[0030] Specifically, as shown in Figure 2 , Figure 5 , Figure 6 As shown, a third gear 26 is fixedly connected to the outer surface of the right walking shaft 30. The outer edge of the third gear 26 meshes with a fourth gear 27. The top of the fourth gear 27 is fixedly connected to a stirring shaft 28. The top of the stirring shaft 28 penetrates through the feeding box 3 and is fixedly connected with stirring blades 13 on the outer surface. The outer surface of the stirring shaft 28 does not contact the baffle 22.
[0031] By adopting the above technical solution, when the trolley 1 moves, a set of rollers 2 installed at the right bottom of the trolley 1 drives the walking shaft 30 to rotate. The walking shaft 30 drives the third gear 26 on its outer surface to rotate. The third gear 26 drives the meshing fourth gear 27 to rotate. The fourth gear 27 drives the stirring shaft 28 at the top to rotate. The stirring shaft 28 drives the stirring blades 13 on its outer surface to rotate, stirring the feed entering the feeding area, so that the feed components are mixed, which helps the hairy crabs ingest more comprehensive and balanced nutrient components and promotes their healthy growth.
[0032] Specifically, as shown in Figure 2 , Figure 3 , Figure 4 As shown, a plurality of blades 15 are fixedly connected to the outer surface of the rotating shaft 14 at equal intervals. The top of the rotating shaft 14 penetrates through the feeding box 3 and is fixedly connected with a reciprocating lead screw 17. The reciprocating lead screw 17 is fixedly connected to the output shaft of the motor 6. The motor 6 is fixedly connected to the top of the control box 5. The control box 5 is fixedly connected to the top of the feeding box 3. A moving block 18 is movably connected to the outer surface of the reciprocating lead screw 17. A plurality of connecting rods 7 are fixedly connected to the outer surface of the moving block 18. The top of the connecting rod 7 is fixedly connected with a brush plate 19. Slide rods 16 are respectively fixedly connected to the four corners of the inner cavity of the feeding box 3. The brush plate 19 is slidably connected to the outer surface of the slide rod 16. Oblique plates 20 are respectively fixedly connected to both sides of the inner wall of the brush plate 19. The oblique plates 20 are inclined with respect to the horizontal plane, and there is a gap between the oblique plates 20 and the side wall of the brush plate 19.
[0033] By adopting the above technical solution, when an operator wants to crush animal feed, the operator turns on the motor 6, so that the motor 6 drives the reciprocating lead screw 17 and the rotating shaft 14 to rotate. The rotating shaft 14 drives the blades 15 on the outer surface to rotate, crushing hard objects carried in the animal feed, such as snails, fish bones, etc. The reciprocating lead screw 17 rotates, driving the moving block 18 on the outer surface to move up and down. The moving block 18 drives the connecting rod 7 to move synchronously. The connecting rod 7 drives the brush plate 19 to move in the inner cavity of the feeding box 3. The brush plate 19 slides on the outer surface of the sliding rod 16 and contacts the inner wall of the feeding box 3, scraping the feed attached to the inner wall of the feeding box 3 onto the bottom of the inner cavity of the feeding box 3, avoiding waste and pollution of the feed, improving the utilization rate of the feed. At the same time, the brush plate 19 drives the inclined plate 20 into the stirred feed layer. Hard objects such as snails and fish bones deposited at the bottom are driven by the inclined plate 20 to move upward, and then fall from the gap between the inclined plate 20 and the side wall of the brush plate 19, making the nutrients in the feed fully mixed and crushed, facilitating the absorption by the hairy crabs and being beneficial to the digestion and molting growth of the hairy crabs.
[0034] Working principle: When an operator wants to crush animal feed, the operator turns on the motor 6, so that the motor 6 drives the reciprocating lead screw 17 and the rotating shaft 14 to rotate. The rotating shaft 14 drives the blades 15 on the outer surface to rotate. The reciprocating lead screw 17 rotates, driving the moving block 18 on the outer surface to move up and down. The moving block 18 drives the connecting rod 7 to move synchronously. The connecting rod 7 drives the brush plate 19 to move in the inner cavity of the feeding box 3. The brush plate 19 slides on the outer surface of the sliding rod 16 and contacts the inner wall of the feeding box 3, scraping the feed attached to the inner wall of the feeding box 3 onto the bottom of the inner cavity of the feeding box 3. At the same time, the brush plate 19 drives the inclined plate 20 into the stirred feed layer. Hard objects such as snails and fish bones deposited at the bottom are driven by the inclined plate 20 to move upward, and then fall from the gap between the inclined plate 20 and the side wall of the brush plate 19. After the feed is stirred and crushed by the stirring device, the operator turns on the control valve 29, so that the feed enters the bottom feeding area. Then the operator pushes the cart 1 to move in the breeding area, so that a set of rollers 2 installed at the left bottom of the cart 1 drives the walking shaft 30 to rotate. The walking shaft 30 drives the first gear 23 on the outer surface to rotate. The first gear 23 drives the meshing second gear 24 to rotate. The second gear 24 drives the driving shaft 25 at the top to rotate. The driving shaft 25 drives the belt 8 on the outer surface to rotate. The belt 8 drives the auxiliary roller 9 in the inner cavity to rotate, so that the belt 8 drives the pusher to rotate synchronously. The push block 10 gradually approaches the moving plate 11 and contacts the moving plate 11, causing the moving plate 11 to move to the right. The moving plate 11 drives the control plate 21 to move synchronously. The control plate 21 gradually stretches the spring 12. At the same time, the moving plate 11 drives the baffle 22 to move, causing the baffle 22 to move to the right. The feed falls from the gap between the feeding box 3 and the baffle 22, evenly distributing the feed in the breeding area.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
