Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to an automatic feeding device for crayfish farming and its usage method. Background Technology

[0002] When raising crayfish, aquaculture farmers need to feed them every day. When feeding, they need to pay attention to distributing the feed evenly and not piling it up together. Otherwise, the feed will sink to the bottom before the crayfish finish eating it. The feed that sinks to the bottom is prone to spoilage and affects the water quality, which further reduces the survival rate of the crayfish.

[0003] Patent publication number CN219781263U discloses a feeding device for rice paddy crayfish farming, including a hopper and a box body; a stop post is slidably connected inside the hopper, the box body is connected to the bottom end of the hopper, a support plate is slidably installed inside the box body, a sliding rod is connected between the support plate and the stop post, a spring is connected between the support plate and the inner wall of the box body, a motor is also connected inside the box body, an eccentric wheel is connected to the output shaft of the motor, and discharge ports are opened on all four sides of the bottom end of the box body, the motor is electrically connected to a controller, and the controller is electrically connected to a timer.

[0004] When using a feeding device for rice paddy crayfish farming, the feed is stored in the hopper. A motor drives an eccentric wheel to rotate. When the eccentric wheel presses against the support plate, it opens the baffle, allowing the feed to fall into the container and then be discharged through the outlet. Guided by the base, the feed is dispersed in all directions, preventing feed accumulation. Since these feeding devices are typically installed on the pond and the outlet is always open, moisture can easily enter the container during rainy weather. This can cause the feed inside to become damp, sticking to the container and potentially clogging the outlet, preventing even distribution. Therefore, this paper proposes an automatic feeding device for crayfish farming that can evenly distribute feed, along with its usage method. Summary of the Invention

[0005] This invention discloses an automatic feeding device for crayfish farming and its usage method, which can evenly distribute feed to overcome the shortcomings of existing feeding devices for rice paddy crayfish farming that cannot evenly distribute feed.

[0006] The technical implementation of the present invention is as follows: an automatic feeding device for crayfish farming, comprising a feeding boat, a guide frame, and a feeding cylinder. The feeding boat is provided with a guide frame, and the feeding cylinder is rotatably connected to the guide frame. It also includes a cover, a hollow cylinder, a feeding assembly, a contact rod, a first spring, and a cover. The feeding cylinder is snapped with a cover. A storage cavity is opened inside the feeding cylinder. The storage cavity is provided with a hollow cylinder, and the hollow cylinder and the storage cavity are connected. A feeding assembly for taking out crayfish feed is provided between the feeding boat and the feeding cylinder. The feeding boat is provided with symmetrically arranged contact rods. A cover is slidably connected to the feeding boat near the contact rod. A first spring is connected between the cover and the feeding boat.

[0007] Furthermore, the material handling assembly includes a multi-stage cylinder, a magnet, a moving column, a material handling plate, loose material sheets, elastic sheets, an elastic rope, and a sliding rod. The multi-stage cylinder is located on the side of the feeding vessel away from the cover. The telescopic rod of the multi-stage cylinder passes through the feeding cylinder, and the multi-stage cylinder is connected to the magnet. The feeding cylinder is slidably connected to the material handling plate. The moving column is connected to the side of the material handling plate away from the contact rod, and the moving column and the magnet are attracted to each other. The sliding rod is slidably connected to the material handling plate, and the sliding rod is pressed against the cover. A limit block is connected to the side of the sliding rod near the material handling plate, and the limit block is in contact with the material handling plate. Multiple loose material sheets are rotatably connected to the side of the sliding rod away from the limit block, and multiple elastic sheets are rotatably connected to the side of the sliding rod near the loose material sheets. The loose material sheets and elastic sheets form an umbrella shape, and an elastic rope connects the loose material sheets and elastic sheets.

[0008] Furthermore, it also includes an airbag, an exhaust pipe, and a baffle net. The side of the feeding cylinder away from the receiving plate is connected to the airbag. The airbag and the receiving plate are squeezed together. The airbag is connected to multiple exhaust pipes. The exhaust pipes are connected to the feeding cylinder and the storage chamber. The exhaust pipes are connected to the baffle net.

[0009] Furthermore, it also includes guides and blocking plates. The guides are slidably connected to the side of the material receiving plate near the loose material plate. The guides and the loose material plate are rotatably connected. The guides are connected to blocking plates, and the blocking plates are folded up to form a circle.

[0010] Furthermore, it also includes a rotating mechanism that drives the material receiving disc to rotate. The rotating mechanism includes a retaining ball, a second spring, a threaded cylinder, and a rotating component. The threaded cylinder is connected to the side of the magnet block away from the multi-stage cylinder. The moving column has an external threaded groove. The threaded cylinder and the moving column are threadedly connected through the external threaded groove. The retaining ball is slidably connected to the side of the moving column near the threaded cylinder. The retaining ball and the threaded cylinder are pressed together. The second spring is connected between the retaining ball and the moving column. The rotating component is slidably connected to the threaded cylinder. The rotating component and the moving column are rotatably connected.

[0011] Furthermore, it also includes an air outlet ring, an air guide pipe, a piston rod, and a third spring. The air outlet ring is located on the side of the feeding vessel near the cover. The air outlet ring is symmetrically connected to the air guide pipe. The air guide pipe is slidably connected to the piston rod. The piston rod and the blocking plate are squeezed together. A third spring is connected between the piston rod and the air guide pipe.

[0012] Furthermore, it also includes guide rails and electric sliders. The feeding vessel is equipped with guide rails, and multiple electric sliders are slidably connected to the guide rails. The electric sliders are connected to the feeding cylinder.

[0013] Furthermore, it also includes a movable ring, a fixed block, a pull rope, and an iron ball. The feeding cylinder is slidably connected to multiple pull ropes, one end of which is connected to a fixed block. The fixed blocks are connected to a movable ring, and the other end of the pull rope is connected to an iron ball.

[0014] Furthermore, it also includes heating rings, with multiple heating rings provided in the feeding cylinder.

[0015] The specific steps for using an automatic feeding device for crayfish farming are as follows:

[0016] S1: Open the lid, pour the shrimp feed into the storage chamber, and then close the lid; S2: Control the cylinder to drive the magnet and the moving column to attract each other, causing the moving column to move down, which in turn moves the feeding plate and the sliding rod down. When the sliding rod and the cover separate, the first spring causes the cover to move down and block the opening of the hollow cylinder, thus preventing water from entering the storage chamber; S3: When the feeding plate moves down and squeezes the air bladder, the air bladder will spray gas through the exhaust pipe, and the gas will blow the shrimp feed upward to prevent it from entering the storage chamber. S4: After the feeding tray reaches below the hollow cylinder, the shrimp feed automatically falls onto the feeding tray; S5: The control cylinder drives the magnet block and the moving column to move upward, causing the feeding tray to move the loose material sheet and the elastic sheet upward. When the sliding rod contacts the cover, it pushes the cover to move upward and open the opening; S6: After the cover moves upward and is blocked by the contact rod, the feeding tray continues to push the loose material sheet and the elastic sheet upward, and the loose material sheet and the elastic sheet automatically open to push the shrimp feed outward and scatter.

[0017] The present invention has the following advantages: 1. During the process of taking out shrimp feed, the feeding component gradually loosens the cover, and the first spring simultaneously drives the cover to move downward to automatically block the opening of the hollow cylinder. In this way, the opening can be blocked in time when taking out the feed, preventing water from entering the storage chamber and preventing the shrimp feed in the storage chamber from clumping when it comes into contact with water, thus affecting the uniformity of subsequent feeding.

[0018] 2. This invention uses multi-stage cylinders to control the magnet block to move the moving column and the feeding plate downwards. The feeding plate also moves the loose material pieces and elastic pieces downwards. The elastic rope automatically pulls the loose material pieces and elastic pieces together, thus expanding the feeding plate's feeding area so that the feeding plate can pick up more shrimp feed.

[0019] 3. When the feeding disc moves downward to pick up the material, the airbag is squeezed and deformed by the feeding disc, so that the gas blows and disperses the shrimp material at the bottom of the storage chamber, so that the material can be evenly distributed in the future.

[0020] 4. In this invention, when the feeding disc moves downward to pick up the material, the blocking plate can block the edge of the feeding disc, thereby allowing more shrimp material to be picked up.

[0021] 5. In this invention, when the threaded cylinder moves upward, the external thread groove drives the moving column to rotate, thereby causing the material taking plate, the elastic plate and the material taking plate to rotate together, so that the residual material on the material taking plate, the material taking plate and the elastic plate is thrown out.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0038] Example 1: An automatic feeding device for crayfish farming, such as... Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the system includes a feeding boat 1, a guide frame 2, a feeding cylinder 3, a cover 4, a hollow cylinder 501, a material-retrieving component, a contact rod 12, a first spring 14, and a cover 15. The feeding boat 1 is equipped with a guide frame 2, and the feeding cylinder 3 is rotatably connected to the guide frame 2. The cover 4 is snapped onto the upper front part of the feeding cylinder 3. A storage cavity 5 for storing shrimp feed is opened in the upper part of the feeding cylinder 3. A hollow cylinder 501 is located in the middle of the storage cavity 5, and the lower part of the hollow cylinder 501 communicates with the storage cavity 5. A material-retrieving component for retrieving shrimp feed is located between the feeding boat 1 and the feeding cylinder 3. The upper middle part of the feeding boat 1 is connected to... Two contact rods 12 are connected. A cover 15 for covering the upper opening of the hollow cylinder 501 is slidably connected to the upper part of the feeding boat 1. A first spring 14 is connected between the lower part of the cover 15 and the feeding boat 1. The material handling assembly includes a multi-stage cylinder 6, a magnet 7, a moving column 8, a material handling plate 9, a material distribution plate 10, an elastic plate 11, an elastic rope 101, and a sliding rod 13. The multi-stage cylinder 6 is bolted to the lower middle part of the feeding boat 1. The telescopic rod of the multi-stage cylinder 6 extends upward into the feeding cylinder 3. A magnet 7 is connected to the top of the telescopic rod of the multi-stage cylinder 6. An internal sliding connection includes a material receiving tray 9. A movable column 8 is fixedly connected to the bottom of the material receiving tray 9. The bottom of the movable column 8 and the top of the magnet block 7 are mutually attracted and engaged. A sliding rod 13 is slidably connected to the middle of the material receiving tray 9. The top of the sliding rod 13 and the bottom of the cover 15 are pressed together. A limit block 130 is fixedly connected to the lower part of the sliding rod 13. The bottom of the limit block 130 contacts the top of the material receiving tray 9. Three material distribution plates 10 are uniformly rotatably connected to the upper part of the sliding rod 13 along the circumference. Three elastic plates 11 are also uniformly rotatably connected to the upper part of the sliding rod 13 along the circumference. The sheet 11 and the loose sheet 10 are distributed alternately, forming an umbrella shape with the loose sheet 10 and the elastic sheet 11. When the sliding rod 13 moves upward and contacts the cover 15, it pushes the cover 15 upward, causing the cover 15 to open the top of the feeding cylinder 3. After the cover 15 is restricted by the contact rod 12, the cover 15 stops moving and pushes the sliding rod 13 downward so that the loose sheet 10 and the elastic sheet 11 can rotate and unfold. In this way, the loose sheet 10 and the elastic sheet 11 automatically push the shrimp feed down. An elastic rope 101 connects the loose sheet 10 and the elastic sheet 11.

[0039] When raising crayfish, it is necessary to feed them regularly. This device can be used for feeding. First, open the cover 4, then introduce the crayfish feed into the discharge chamber, and then close the cover 4. Next, place the feeding boat 1 on the water surface and start the feeding boat 1. The feeding boat 1 will then move automatically on the water surface. Then, start collecting the feed. You can first control the extension rod of the multi-stage cylinder 6 to extend it. The extension of the extension rod of the multi-stage cylinder 6 will drive the magnet 7 to move upward. When the magnet 7 moves upward and contacts the bottom of the moving column 8, it can attract the moving column 8. Then, you can control... The telescopic rod of the multi-stage cylinder 6 retracts, which in turn drives the moving column 8 downward via the magnet 7. The downward movement of the moving column 8 causes the loose material sheet 10, the elastic sheet 11, and the sliding rod 13 to move downward. As the sliding rod 13 slowly moves downward, it loosens from the cover 15. At this point, the elastic rope 101, which was originally in a stretched state, begins to contract. The elastic rope 101 then causes the loose material sheet 10 and the elastic sheet 11, which were originally in an unfolded state, to tighten. This causes the loose material sheet 10 and the elastic sheet 11 to gradually close from an open umbrella shape to a folded umbrella shape. Figure 2 The state becomes Figure 7As shown, the area for picking up shrimp feed on the feeding tray 9 gradually expands to allow for the collection of more shrimp feed. As the sliding rod 13 slowly moves downwards and separates from the cover 15, the first spring 14, which was originally compressed, begins to pull. Under the action of the first spring 14, the cover 15 moves downwards, gradually blocking the opening at the top of the hollow cylinder 501. In this way, while the feeding tray 9 moves downwards to pick up feed, the cover 15 can promptly block the opening of the hollow cylinder 501, preventing moisture from entering the storage chamber 5 through the opening and avoiding the shrimp feed from becoming damp and clumping. This ensures that the shrimp feed is distributed more evenly during subsequent feeding. After the feeding tray 9 moves downwards to below the hollow cylinder 501, the shrimp feed in the storage chamber 5 will fall to the upper part of the feeding tray 9. Then, the extension rod of the multi-stage cylinder 6 can be controlled to extend, driving the magnet block 7 and the moving column 8 to move upwards. The moving column 8 drives the feeding tray 9, the dispersing plate 10, the elastic plate 11, and the sliding rod 13 to move upwards. When the top of the sliding rod 13 contacts the cover 15, because the elastic force of the elastic rope 101 is greater than the elastic force of the first spring 14, when the sliding rod 13 pushes the cover 15, the cover 15 will be lifted upwards first. When pushed, the first spring 14 is compressed, and the loose material sheet 10 and the elastic sheet 11 do not unfold. The cover 15 moves upward and automatically opens the opening of the hollow cylinder 501. When the cover 15 contacts the bottom end of the contact rod 12, the contact rod 12 will stop the cover 15, and the cover 15 will no longer move upward. The top of the sliding rod 13 is blocked by the cover 15, causing the sliding rod 13 and the limit block 130 to stop moving as well. Since the upper parts of the loose material sheet 10 and the elastic sheet 11 are rotatably connected to the upper part of the sliding rod 13, the upper parts of the loose material sheet 10 and the elastic sheet 11 also no longer move. At this time, the material picking tray 9 will continue to move towards... As the feed plate 10 and elastic plate 11 move upwards, the feed plate 9 squeezes and expands them, and the elastic rope 101 is pulled. When the top middle of the feed plate 9 contacts the limiting block 130, the limiting block 130 blocks the feed plate 9 and prevents it from moving upwards. At this time, the multi-stage cylinder 6 can be turned off. While the feed plate 10 and elastic plate 11 are expanded, the shrimp feed on the feed plate 9 can be automatically pushed outwards. The shrimp feed will slide down along the feeding cylinder 3 and fall into the water through the outer wall of the feeding cylinder 3. In this way, the shrimp feed can be evenly distributed to feed the crayfish. After feeding is completed, the feeding boat 1 can be turned off.

[0040] Example 2: Based on Example 1, such as Figures 5-7As shown, it also includes an airbag 18, an exhaust pipe 19, and a baffle net 20. The airbag 18 is connected to the bottom center of the feeding cylinder 3. The upper part of the airbag 18 is squeezed and fitted to the bottom of the feeding plate 9. Eight exhaust pipes 19 are evenly connected to the upper part of the airbag 18 along the circumferential direction. The exhaust pipes 19 are connected to the lower part of the feeding cylinder 3. The upper part of the exhaust pipes 19 is connected to the storage chamber 5. When the feeding plate 9 moves down and squeezes the airbag 18, the airbag 18 contracts and discharges gas into the storage chamber 5, so as to blow away the shrimp feed in the storage chamber 5 and also help to blow the shrimp feed onto the feeding plate 9. The upper part of the exhaust pipes 19 is connected to a baffle net 20. The baffle net 20 is used to block the shrimp feed and prevent the shrimp feed from entering the airbag 18 through the exhaust pipes 19.

[0041] As mentioned earlier, shrimp feed is introduced into the storage chamber 5. Since the storage chamber 5 and the hollow cylinder 501 are connected, the shrimp feed will also enter the hollow cylinder 501. This shrimp feed may affect the movement of the feeding disc 9 within the hollow cylinder 501, potentially impacting its feeding function. Therefore, an airbag 18 is provided. Before the feeding disc 9 picks up feed, the airbag 18 is fully inflated, with its top completely blocking the bottom of the hollow cylinder 501. This prevents shrimp feed from the storage chamber 5 from entering the hollow cylinder 501, overcoming the aforementioned drawbacks. When the feeding disc 9 moves downwards and contacts the airbag 18, it slowly compresses and contracts the airbag 18. Originally, the airbag 18 just blocked the bottom of the hollow cylinder 501; after the airbag 18 contracts and deforms, it... As the bottom of the hollow cylinder 501 and the air bladder 18 slowly separate, and the feeding tray 9 moves completely below the hollow cylinder 501, the shrimp feed can fall onto the feeding tray 9. When the air bladder 18 contracts and deforms, the gas inside the air bladder 18 will be discharged into the storage chamber 5 through the exhaust pipe 19. This gas can blow the shrimp feed at the bottom of the storage chamber 5 upward and disperse it. This not only disperses the shrimp feed piled up, but also helps to blow the shrimp feed onto the feeding tray 9, speeding up the feeding tray 9 to pick up the feed. After the feeding tray 9 finishes picking up the feed, it will move upward. After the feeding tray 9 and the air bladder 18 separate, the air bladder 18 will expand and return to its original position. By repeating the above operation, the shrimp feed at the bottom of the storage chamber 5 can be automatically blown and dispersed during the feeding process of the feeding tray 9, so that the feed can be evenly distributed later.

[0042] like Figures 3-4 As shown, it also includes guides 16 and blocking plates 17. The guides 16 are slidably connected to the four sides of the upper part of the feeding tray 9. The upper part of the guides 16 is rotatably connected to the bottom of the loose material plate 10. The outer ends of the guides 16 are connected to blocking plates 17 for blocking shrimp feed. The four blocking plates 17 are gathered together to form a circle, which can surround the top edge of the feeding tray 9.

[0043] When the feeding tray 9 picks up shrimp feed, because the top of the feeding tray 9 is flat and there are no parts to block the shrimp feed, the feeding tray 9 can only pick up a thin layer of shrimp feed each time, resulting in a small amount of feed picked up and a small amount of feed fed each time. In order to overcome the above shortcomings, a blocking plate 17 is set up to block the shrimp feed, thereby increasing the amount of feed picked up each time. When the feeding tray 9 moves the elastic plate 11 and the loose feed plate 10 downward, it will also move the guide 16 and the blocking plate 17 downward. Moreover, before the feeding tray 9 moves downward into the hollow cylinder 501, the elastic plate 11 and the loose feed plate 10 will completely close up. At the same time, the loose feed plate 10 will also move the guide 16 and the blocking plate 17 downward. The plate 17 moves inward, and the four blocking plates 17 can just surround the top edge of the feeding tray 9. Then, after the feeding tray 9 moves the blocking plates 17 downward to below the hollow cylinder 501, the shrimp feed will fall into the feeding tray 9. Under the blocking effect of the blocking plates 17, the thickness of the shrimp feed obtained can be consistent with the height of the blocking plates 17, which can increase the amount of feed. Afterward, the feeding tray 9 moves the blocking plates 17 upward to above the feeding cylinder 3. When the loose material plate 10 unfolds, it will also drive the guide 16 and the blocking plates 17 to move outward and reset. When the four blocking plates 17 move outward, the blocking plates 17 no longer block the shrimp feed, and the shrimp feed will automatically fall.

[0044] like Figure 8 As shown, it also includes a rotating mechanism, which includes a retaining ball 21, a second spring 22, a threaded cylinder 24, and a rotating component 240. The top of the magnet block 7 is fixedly connected to the threaded cylinder 24. The outer side of the moving column 8 has an external threaded groove 23. The threaded cylinder 24 and the moving column 8 are threadedly connected through the external threaded groove 23. The lower part of the moving column 8 is slidably connected to the retaining ball 21. The retaining ball 21 and the top of the threaded cylinder 24 are pressed together. The second spring 22 is connected between the retaining ball 21 and the moving column 8. The rotating component 240 is slidably connected to the threaded cylinder 24. The top of the rotating component 240 and the bottom of the moving column 8 are rotatably connected.

[0045] When the feeding disc 9 moves downwards, causing the loose material sheet 10 and elastic sheet 11 to move downwards to collect the shrimp feed, some shrimp feed may fall onto the loose material sheet 10 and elastic sheet 11. After the loose material sheet 10 and elastic sheet 11 expand outwards and push the shrimp feed out, some shrimp feed may remain on the loose material sheet 10, elastic sheet 11, and feeding disc 9. In humid weather, this shrimp feed can easily stick to the loose material sheet 10, elastic sheet 11, and feeding disc 9, resulting in residual shrimp feed on these surfaces. To prevent excess shrimp feed from remaining on the loose material sheet 10, elastic sheet 11, and feeding disc 9, a rotating mechanism is installed. When the multi-stage cylinder 6 controls the magnet block 7 to move upwards, the magnet block 7 will drive the threaded cylinder 24 upwards. As the threaded cylinder 24 moves upward, the top of it is blocked by the retaining ball 21. Because the elasticity of the second spring 22 is greater than that of the first spring 14 and the elastic rope 101, the retaining ball 21 will not be squeezed into the threaded cylinder 24. When the threaded cylinder 24 moves upward, it will cause the retaining ball 21 to move upward. The retaining ball 21 will cause the moving column 8 to move upward, which in turn will cause the picking plate 9 and the sliding rod 13 to move upward. The sliding rod 13 will push the cover 15 upward, so that the cover 15 is stopped by the contact rod 12. Then, the sliding rod 13 and the limiting block 130 will stop moving. When the picking plate 9 continues to move upward and is stopped by the limiting block 130, the picking plate 9 will stop moving upward. Since the picking plate 9 and the moving column 8 are fixedly connected, the moving column 8 will also stop moving. The upward movement continues, and the extension rod of the multi-stage cylinder 6 can be further controlled to move the magnet 7 and the threaded cylinder 24 upward. The threaded cylinder 24 will then press the retaining ball 21 into the moving column 8, compressing the second spring 22. This causes the threaded cylinder 24 to move upward a certain distance, and the threaded cylinder 24 will drive the moving column 8 to rotate 35 degrees clockwise through the external thread groove 23. The moving column 8 will then drive the material picking plate 9 to rotate as well, causing the material picking plate 9 to drive the loose material plate 10 and the elastic plate 11 to rotate 35 degrees clockwise. This automatically throws out the residual material on the material picking plate 9, the loose material plate 10, and the elastic plate 11. Afterward, when the extension rod of the multi-stage cylinder 6 retracts, it will drive the magnet 7 to move downward, and the magnet 7 will drive the threaded cylinder 24 to move downward. 4. Moving downwards, the threaded cylinder 24 will first drive the moving column 8 and the retaining ball 21 to move downwards. The moving column 8 will then drive the picking plate 9 to move downwards. When the bottom of the picking plate 9 contacts the air bladder 18, it will be blocked by the air bladder 18, causing the picking plate 9 and the moving column 8 to stop moving downwards. At this time, the threaded cylinder 24 will continue to move downwards. The threaded cylinder 24 will drive the moving column 8 to rotate counterclockwise by 35 degrees. After the threaded cylinder 24 and the retaining ball 21 separate, under the action of the second spring 22, the retaining ball 21 will move and reset. When the threaded cylinder 24 contacts the top of the rotating part 240, the threaded cylinder 24 will drive the rotating part 240 to move downwards. The downward movement of the rotating part 240 will then drive the moving column 8 and the picking plate 9 to continue moving downwards.

[0046] like Figures 9-10 As shown, it also includes an air outlet ring 25, an air guide pipe 26, a piston rod 27, and a third spring 28. An air outlet ring 25 is provided in the middle of the upper part of the feeding boat 1. The air outlet ring 25 is connected to the air guide pipe 26 on both the left and right sides. The piston rod 27 is slidably connected to the lower part of the air guide pipe 26. The piston rod 27 and the baffle plate 17 are pressed together. The third spring 28 is connected between the side of the piston rod 27 that is close to each other and the air guide pipe 26. The third spring 28 is wound around the piston rod 27. When the baffle plate 17 moves outward, it can push the piston rod 27 outward, so that the gas is sprayed out through the air outlet ring 25 to blow the shrimp feed off.

[0047] When the blocking plate 17 moves inward, it slowly releases the piston rod 27, and the initially compressed third spring 28 is pulled back to its original position, causing the piston rod 27 to move closer together. Then, if the blocking plate 17 moves outward, it will push the piston rod 27 away from each other, thus compressing the third spring 28. The piston rod 27 will blow gas out through the air outlet ring 25, so that the gas can blow the shrimp feed on the feeding plate 9 and the feeding cylinder 3 downward for feeding.

[0048] like Figures 11-12 As shown, it also includes a guide rail 29 and an electric slider 30. The feeding boat 1 is provided with a guide rail 29, and four electric sliders 30 are uniformly slidably connected on the guide rail 29. The top of the electric slider 30 is connected to the bottom of the feeding cylinder 3.

[0049] After the shrimp feed falls onto the outer wall of the feeding cylinder 3, it will slide down the outer wall. Since the feeding cylinder 3 floats on the water surface, some water may splash onto the outer wall of the feeding cylinder 3. This can cause the shrimp feed to stick to the outer wall of the feeding cylinder 3 after contact with the water. In order to clean the shrimp feed off the outer wall of the feeding cylinder 3, a guide rail 29 and an electric slider 30 are set up. The electric slider 30 drives the feeding cylinder 3 to rotate counterclockwise. The centrifugal force can throw the shrimp feed off the outer wall of the feeding cylinder 3 and also expand the range of shrimp feed scattering, making the feeding range wider.

[0050] like Figures 13-14 As shown, it also includes a moving ring 31, a fixing block 32, a pull rope 33 and an iron ball 34. Four pull ropes 33 are evenly slidably connected to the upper part of the feeding cylinder 3 along the circumferential direction. The upper end of each pull rope 33 is connected to a fixing block 32. The fixing block 32 is located on the outer wall of the feeding cylinder 3. The top of the fixing block 32 is connected to the moving ring 31. The lower end of each pull rope 33 is connected to an iron ball 34.

[0051] As the shrimp feed in the storage chamber 5 gradually decreases, some shrimp feed may stick to the inner wall of the storage chamber 5. In order to avoid wasting shrimp feed, it is necessary to knock the shrimp feed off the inner wall of the storage chamber 5. You can lift the moving ring 31 upwards by hand, so that the moving ring 31 drives the fixed block 32 and the pull rope 33 to move upwards. The pull rope 33 then drives the iron ball 34 to move upwards. After that, release the moving ring 31. Under the action of the gravity of the iron ball 34, it will quickly drive the iron ball 34 and the moving ring 31 to move downwards and reset. The iron ball 34 will then automatically knock the feeding cylinder 3, thus knocking off the residual shrimp feed on the inner wall of the storage chamber 5.

[0052] like Figure 2 As shown, it also includes a heating ring 35, and two heating rings 35 are provided in the lower part of the feeding cylinder 3.

[0053] In order to prevent water from sticking to the outer wall of the feeding cylinder 3, which would cause the shrimp feed and water to stick together and be difficult to fall, a heating ring 35 is set up. The heating ring 35 can dry the feeding cylinder 3, keeping the feeding cylinder 3 in a dry state so as to guide the shrimp feed.

[0054] Example 3: Based on Example 2, an automatic feeding method for crayfish farming is described, with the following specific steps:

[0055] S1: Open the lid 4, pour the shrimp feed into the storage chamber 5 for storage, and then close the lid 4;

[0056] S2: The control cylinder drives the magnet 7 and the moving column 8 to attract each other, so that the moving column 8 moves down and drives the material picking plate 9 and the sliding rod 13 to move down. When the sliding rod 13 and the cover 15 separate, the first spring 14 drives the cover 15 to move down and block the opening of the hollow cylinder 501, thus preventing water from entering the storage chamber 5.

[0057] S3: When the feeding plate 9 moves down and squeezes the air bag 18, the air bag 18 will spray gas through the exhaust pipe 19, and the gas will blow the shrimp feed upward to prevent the shrimp feed from clumping.

[0058] S4: After the feed tray 9 is below the hollow cylinder 501, the shrimp feed will automatically fall onto the feed tray 9;

[0059] S5: The control cylinder drives the magnet block 7 and the moving column 8 to move upward, so that the material picking plate 9 drives the loose material piece 10 and the elastic piece 11 to move upward. When the sliding rod 13 contacts the cover 15, it pushes the cover 15 to move upward and open the opening.

[0060] S6: After the cover 15 moves upward and is blocked by the contact rod 12, the feeding plate 9 continues to push the loose material piece 10 and the elastic piece 11 upward, and the loose material piece 10 and the elastic piece 11 automatically open to push the shrimp feed outward and scatter.

[0061] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
