Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, specifically a feeding equipment for ecological seedling cultivation of river crab seedlings. Background Technology

[0002] In the process of raising crab seedlings, feed is usually transported to the breeding pond manually for feeding. This method is very inefficient and requires a lot of labor for the feeders. Therefore, a feeding device for ecological breeding of crab seedlings is needed to solve the problem of feeding crab seedlings.

[0003] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the existing technology: Traditional feeding equipment for ecological breeding of river crab seedlings generally requires manual addition of feed to the receiving scoop, necessitating refilling after each feeding. This increases the labor intensity of operators, reduces the accuracy of feed addition, and diminishes the efficiency and convenience of the feeding equipment. Furthermore, it is inconvenient to control the feeding distance during use. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a feeding device for ecological breeding of crab seedlings. This solves the problem that current feeding devices for ecological breeding of crab seedlings generally require manual addition of feed to the receiving scoop of the feeding device. This means that feed needs to be added every time it is fed, which increases the labor intensity of the operator, reduces the accuracy of feed addition and the efficiency and convenience of feeding. Furthermore, it is inconvenient to control the feeding distance when using the feeding device.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A feeding device for ecological seedling cultivation of river crabs is designed, including a feeding vehicle body. A feeding hopper is fixedly connected to one side of the upper surface of the feeding vehicle body, and a quantitative discharging mechanism is installed on one side of the feeding hopper. A support beam is fixedly connected to the other side of the upper surface of the feeding vehicle body. A rotating shaft is rotatably connected to the support beam. A support arm is rotatably connected to the middle of the rotating shaft. A receiving scoop is fixedly connected to the other end of the support arm. One end of the rotating shaft movably passes through one side of the support beam and is fixedly connected to one end of a first gear. A second gear is installed around the periphery of the first gear. A connecting arm is fixedly connected to one side of the second gear. The other end of the connecting arm is fixedly connected to one side of the support arm. The other end of the rotating shaft movably passes through the other side of the support beam and is fixedly connected to the center of a first pulley. One end of the first pulley is sleeved on one end of a transmission belt, and the other end of the transmission belt is sleeved on the outside of the second pulley. One end of the second pulley is rotatably connected to the outer surface of the support beam.

[0006] Preferably, the quantitative discharge mechanism includes a discharge trough, one end of which is fixedly connected to the side of the loading hopper, a slot is provided at the bottom of the discharge trough, a baffle is movably connected inside the slot, support plates are fixedly installed on both sides of the discharge trough, a guide rod is movably connected through the middle of the support plate, and a first spring is sleeved on the outside of the guide rod.

[0007] Preferably, one end of the first spring abuts against the upper surface of the support plate, the other end of the first spring abuts against the bottom surface of the top end of the guide rod, and the other end of the guide rod is fixedly connected to both sides of the baffle.

[0008] Preferably, the first gear has a plurality of convex grooves evenly distributed on it, and a first tooth plate is inserted into the inside of the convex groove. The first gear is detachably installed and removed from the first gear by screws.

[0009] Preferably, the inner ring of the second gear is evenly provided with a plurality of triangular grooves, and a second tooth plate is inserted into the inside of the triangular grooves. The second tooth plate is detachably installed with the second gear by screws, and the second tooth plate meshes with the first tooth plate.

[0010] Preferably, a sleeve post is fixedly connected to the upper surface of the feeding vehicle body, a second spring is installed inside the sleeve post, the other end of the second spring abuts against one end of an extension post, one end of the extension post is slidably connected to the inner wall of the sleeve post, and the other end of the extension post abuts against the bottom surface of the support arm.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When feeding is required for the ecological breeding of crab seedlings, the operator first drives the second pulley to rotate via a crank handle. The second pulley then drives the first pulley to rotate via a transmission belt. The first pulley then drives the rotating shaft to rotate on the support beam. At this time, the rotating shaft drives the feeding scoop on the support arm to perform a circular motion. During this process, the other end of the rotating shaft drives the second gear on the second gear to perform a circular motion via the first toothed plate on the first gear. During this process, the support arm compresses the second spring through the extension column, and the extension column retracts into the sleeve column. When the second toothed plate disengages from the first toothed plate, the second spring generates a rebound force on the extension column, thereby causing the support arm to drive the feeding scoop to rotate on the rotating shaft, so that the feed in the feeding scoop is thrown out, thus feeding the crab seedlings in the breeding pond. This reduces the labor intensity of the operator when feeding the crab seedlings in the breeding pond and helps to improve the efficiency and convenience of feeding crab seedlings in the ecological breeding of crabs.

[0013] When the receiving scoop touches the baffle, it moves the baffle downwards. At this time, the two sides of the baffle move the guide rod downwards. The guide rod then compresses the first spring, causing the upper part of the baffle to retract into the slot. The feed in the hopper then flows out from the discharge trough and into the receiving scoop. When the receiving scoop rebounds, the first spring exerts a spring force on the guide rod, causing the guide rod to move the baffle back to its original position, thus blocking the discharge port of the discharge trough and preventing the feed in the hopper from flowing out. This achieves automatic quantitative feeding into the receiving scoop, saving operators time when spreading feed and further improving the efficiency and convenience of the feeding equipment for the ecological breeding of crab seedlings.

[0014] When the pressure of the support arm on the second spring needs to be adjusted, the operator can increase or decrease the number of first tooth plates on the first gear as needed, thereby adjusting the circumference of the second gear rotation and thus controlling the distance of each feeding by the feeding device.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: A feeding device for ecological seedling raising of river crabs, see [link to example]. Figures 1 to 6 The system includes a feeding vehicle body 1. A feeding hopper 11 is fixedly connected to one side of the upper surface of the feeding vehicle body 1. A quantitative discharging mechanism is installed on one side of the feeding hopper 11. The quantitative discharging mechanism includes a discharging trough 23. One end of the discharging trough 23 is fixedly connected to one side of the feeding hopper 11. A slot 24 is opened at the bottom of the discharging trough 23. A baffle 25 is movably connected inside the slot 24. Support plates 26 are fixedly installed on both sides of the discharging trough 23. A guide rod 27 is movably connected through the middle of the support plate 26. A first spring 28 is sleeved on the outside of the guide rod 27. One end of the first spring 28 abuts against the upper surface of the support plate 26, and the other end of the first spring 28 abuts against the bottom surface of the top of the guide rod 27. The other end of the guide rod 27 is fixedly connected to both sides of the baffle 25. When the receiving scoop 15 abuts against the baffle 25, This will cause the baffle 25 to move downwards. At this time, the two sides of the baffle 25 will cause the guide rod 27 to move downwards. The guide rod 27 will then compress the first spring 28, causing the upper part of the baffle 25 to retract into the slot 24. At this time, the feed in the hopper 11 will flow out from the discharge trough 23 and into the receiving spoon 15. When the receiving spoon 15 rebounds, the first spring 28 will generate a spring force on the guide rod 27, causing the guide rod 27 to drive the baffle 25 to reset, thus blocking the discharge port of the discharge trough 23 and preventing the feed in the hopper 11 from flowing out. This achieves automatic quantitative feeding into the receiving spoon 15, saving the operator's time when feeding and improving the efficiency and convenience of feeding equipment for crab seedlings in ecological breeding.

[0026] A support beam 12 is fixedly connected to the other side of the upper surface of the feeding vehicle body 1. A rotating shaft 13 is rotatably connected to the support beam 12. A support arm 14 is rotatably connected to the middle of the rotating shaft 13. A receiving spoon 15 is fixedly connected to the other end of the support arm 14. One end of the rotating shaft 13 extends through one side of the support beam 12 and is fixedly connected to one end of the first gear 16. A second gear 17 is installed around the first gear 16. A connecting arm 18 is fixedly connected to one side of the second gear 17. The other end of the connecting arm 18 is fixedly connected to one side of the support arm 14. The other end of the rotating shaft 13 extends through the other side of the support beam 12 and is fixedly connected to the center of the first pulley 2. One end of the first pulley 2 is fitted around one end of the transmission belt 21. The other end of the transmission belt 21 is fitted around the outside of the second pulley 22. One end of the second pulley 22 is rotatably connected to the outer side of the support beam 12. When the crab seedlings need to be fed, the operator first drives the second pulley 22 to rotate by cranking the handle, and then the second pulley... The pulley 22 drives the first pulley 2 to rotate via the transmission belt 21. The first pulley 2 then drives the rotating shaft 13 to rotate on the support beam 12. At this time, the rotating shaft 13 drives the receiving spoon 15 on the support arm 14 to perform a circular motion. During this process, the other end of the rotating shaft 13 drives the second gear 17 on the second gear 17 to perform a circular motion via the first toothed plate 3 on the first gear 16. During this process, the support arm 14 compresses the second spring 34 through the extension column 35. At the same time, the extension column 35 retracts into the sleeve column 33. When the second toothed plate 32 disengages from the first toothed plate 3, the second spring 34 will generate a rebound force on the extension column 35, thereby causing the support arm 14 to drive the receiving spoon 15 to rotate on the rotating shaft 13, so that the feed in the receiving spoon 15 is thrown out, thereby achieving the purpose of feeding the crab seedlings in the breeding pond. This reduces the labor intensity of the operators when feeding the crab seedlings in the breeding pond and helps to further improve the efficiency and convenience of feeding the crab seedlings in the ecological breeding of crab seedlings.

[0027] It should be noted that the tension of the transmission belt 21 is twice the sum of the maximum elastic forces of the second spring 34 and the first spring 28, so that the transmission belt 21 will not slip on the first pulley 2 and the second pulley 22.

[0028] For details, see Figure 6The first gear 16 has multiple convex grooves 29 evenly distributed on it. The first tooth plate 3 is inserted into the inside of the convex groove 29. The first gear 16 is detachably installed and detached from the first gear 16 by screws. The inner ring of the second gear 17 has multiple triangular grooves 31 evenly distributed on it. The second tooth plate 32 is inserted into the inside of the triangular groove 31. The second tooth plate 32 is detachably installed and detached from the second gear 17 by screws. The second tooth plate 32 meshes with the first tooth plate 3. When the pressure of the support arm 14 on the second spring 34 needs to be adjusted, the operator can appropriately increase or decrease the number of first tooth plates 3 on the first gear 16 as needed, thereby adjusting the circumference of the rotation of the second gear 17, thus controlling the distance of each feeding by the feeding device.

[0029] Further, see Figure 3 and Figure 5 A sleeve post 33 is fixedly connected to the upper surface of the feeding vehicle body 1. A second spring 34 is installed inside the sleeve post 33. The other end of the second spring 34 abuts against one end of the extension post 35. One end of the extension post 35 is slidably connected to the inner wall of the sleeve post 33, and the other end of the extension post 35 abuts against the bottom surface of the support arm 14. When the second toothed plate 32 disengages from the first toothed plate 3, the second spring 34 will generate a rebound force on the extension post 35, thereby enabling the support arm 14 to rotate on the rotating shaft 13. The magnitude of the rebound force of the second spring 34 on the extension post 35 is proportional to the magnitude of the squeezing force of the support arm 14 on the second spring 34 through the extension post 35.
