A feeding device for a crab culture pond

Abstract

This utility model discloses a feeding device for crab farming ponds, comprising four pillars. Upper and lower fixed plates are fixedly installed on the sides of the four pillars, which are close to each other. A feeding box is provided on one side of each pillar, and a feeding pump is fixedly installed on the side of the feeding box. A feeding hose is fixedly installed at the discharge end of the feeding pump, with the end of the feeding hose away from the feeding pump passing through the top of the upper fixed plate. In summary, feed enters the feeding box and is transported by the feeding pump and feeding hose to the annular groove of the annular block. Initially, the moving ring blocks the feeding port, preventing feed from being thrown out. When enough feed is stored in the annular groove, a timer activates the external electric telescopic rod, causing the moving ring to move downwards, opening the feeding port. The motor drives the annular block to rotate, using centrifugal force to throw out the feed, achieving uniform feeding. When the feeding range needs to be adjusted, the internal electric telescopic rod is activated, moving the annular block up and down, changing the height of the feeding port, causing the feed to fall in a parabolic trajectory, thus changing the feeding area.

Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, and in particular to a feeding device for crab farming ponds. Background Technology

[0002] Crabs, also known as "river crabs" and "hairy crabs," have a square-round carapace formed by the fusion of their head and thorax. This carapace is hard and has a pair of eyes at the front of their body, and two pairs of very sharp teeth on their sides. The frontmost pair of appendages are called chelipeds, covered with fine hairs; behind the chelipeds are four pairs of laterally compressed and relatively long walking legs; the abdominal appendages are degenerate. Crab farming refers to the techniques used to cultivate crabs. Crabs are one of the most important freshwater crab species in China, prized for their tender, delicious meat and rich nutritional value. Due to their strong adaptability and wide range of cultivation, crab farming has rapidly increased in recent years, bringing significant economic benefits to farmers.

[0003] According to the existing patent publication number CN218999265U, a feeding device for a high-density crab farming pond includes a ground, a farming trough on the top of the ground, a feeding box fixedly installed on the top of the ground, a storage trough inside the feeding box, and a suction trough inside the feeding box. Because the direction of the suction hose is fixed, and the feeding disc cannot store feed but can be directly fed, the feeding is uneven. In addition, the height of the feeding port cannot be adjusted, and the feeding area cannot be changed. Therefore, we propose a feeding device for a crab farming pond. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for crab farming ponds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a crab farming pond, comprising four pillars, with an upper fixed plate and a lower fixed plate fixedly installed on the sides of the four pillars close to each other. A feeding box is provided on one side of each of the four pillars, and a feeding pump is fixedly installed on the side of the feeding box. A feeding hose is fixedly installed at the discharge end of the feeding pump, with the end of the feeding hose away from the feeding pump penetrating the top of the upper fixed plate. A fixed frame is installed at the bottom of the upper fixed plate, and the feeding hose corresponds to the position of the fixed frame. A telescopic frame is slidably sleeved on the fixed frame, and an internal electric telescopic rod is fixedly installed at the bottom of the upper fixed plate. A connecting rod is fixedly installed at the output end of the internal electric telescopic rod. An annular block is rotatably fitted onto the internal electric telescopic rod via a rotating mechanism at the bottom end of the connecting rod. An annular groove is formed at the top of the annular block. The telescopic frame is slidably connected to the inner wall of the annular groove. Multiple evenly arranged rectangular dispensing ports are formed on the inner wall of the annular groove away from the internal electric telescopic rod. A moving ring is installed on the connecting rod via a vertical moving mechanism. The moving ring is slidably fitted onto the side of the annular block. The moving ring corresponds to the position of the multiple rectangular dispensing ports. A timer is fixedly installed on the top of the dispensing box. The timer is connected to the vertical moving mechanism.

[0006] Preferably, the rotating mechanism includes a motor fixedly installed at the bottom end of the connecting rod, the output end of the motor is fixedly connected to a U-shaped fixing rod, and the two ends of the U-shaped fixing rod are fixedly connected to the side of the annular block through fixing rods.

[0007] Preferably, the up-and-down moving mechanism includes a support plate fixedly sleeved on the connecting rod, and two external electric telescopic rods are fixedly installed on the side of the moving ring, with the output ends of the two external electric telescopic rods fixedly installed on the top of the support plate.

[0008] Preferably, a connecting shaft is fixedly installed on the side of the telescopic frame, and an inner ring is fixedly installed on the other end of the connecting shaft. An annular rotating groove is formed on the inner wall of the annular groove, and the inner ring is rotatably installed in the annular rotating groove.

[0009] Preferably, the feed end of the pump is connected to the interior of the delivery box.

[0010] Preferably, a funnel is fixedly installed at the top center of the dispensing box.

[0011] In summary, feed is fed into the feeding box through a funnel. The pump and motor are then activated, and the feed is transported via a suction hose, a fixed frame, and a telescopic frame into the annular groove of the annular block. Initially, the moving ring blocks the feeding port, preventing feed from being thrown out. Once enough feed is stored in the annular groove, a timer activates the external electric telescopic rod, causing the moving ring to move downwards, opening the feeding port. The motor then drives the annular block to rotate, using centrifugal force to throw the feed out of the feeding port, achieving uniform feeding and avoiding uneven feeding caused by a fixed suction hose orientation. When the feeding range needs adjustment, the internal electric telescopic rod is activated, moving the annular block up and down, changing the height of the feeding port, causing the feed to fall in a parabolic trajectory, thus changing the feeding area.

[0017] The technical solutions of the present utility model 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 utility model, and not 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 effort are within the protection scope of the present utility model.

[0018] Example: Reference Figure 1-4The feeding device for a crab farming pond shown includes four support pillars 9. An upper fixed plate 7 and a lower fixed plate 10 are fixedly installed on the sides of the four support pillars 9, which are close to each other. A feeding box 3 is provided on one side of each support pillar 9. A feeding pump 2 is fixedly installed on the side of the feeding box 3. A feeding hose 5 is fixedly installed at the discharge end of the feeding pump 2. The end of the feeding hose 5 away from the feeding pump 2 passes through the top of the upper fixed plate 7. A fixed frame 18 is installed at the bottom of the upper fixed plate 7. The feeding hose 5 corresponds to the fixed frame 18. A telescopic frame 22 is slidably sleeved on the fixed frame 18. An internal electric telescopic rod 20 is fixedly installed at the bottom of the upper fixed plate 7. A connecting rod 13 is fixedly installed at the output end of the device. An annular block 16 is rotatably sleeved on the internal electric telescopic rod 20 at the bottom end of the connecting rod 13 via a rotating mechanism. An annular groove is provided at the top of the annular block 16. The telescopic frame 22 is slidably connected to the inner wall of the annular groove. Multiple evenly arranged rectangular feeding ports 17 are provided on the inner wall of the annular groove away from the internal electric telescopic rod 20. A moving ring 15 is installed on the connecting rod 13 via a vertical moving mechanism. The moving ring 15 is slidably sleeved on the side of the annular block 16. The positions of the moving ring 15 and the multiple rectangular feeding ports 17 correspond to each other. A timer 6 is fixedly installed on the top of the feeding box 3. The timer 6 is connected to the vertical moving mechanism.

[0019] With the above structure: When the user starts the feed pump 2, the feed is conveyed through the feed hose 5, fixed frame 18, and telescopic frame 22 into the annular groove on the annular block 16. Initially, the moving ring 15 blocks the four feeding ports 17, preventing feed from being thrown out. After a period of conveying, once a certain amount of feed is stored in the annular groove, the timer 6 activates the up-and-down moving mechanism, causing the moving ring 15 to move downwards, thus allowing the four feeding ports 17 to leak out. Due to centrifugal force, the feed is flung out along the four feeding ports 17, achieving the effect of spreading the feed. This allows for spraying after a certain amount has been stored, preventing uneven spreading due to the fixed orientation of the feed hose 5. When it is necessary to change the spreading range, the internal electric telescopic rod 20 is activated, which moves the annular block 16 downwards and then upwards, causing the positions of the four feeding ports 17 to change downwards and then upwards. This change in the height of the feeding ports 17 causes the feed to fall in a parabolic trajectory, resulting in different areas where the feed falls and thus changing the feeding area.

[0020] As shown in the figure, the rotating mechanism includes a motor 12 fixedly installed at the bottom of the connecting rod 13. The output end of the motor 12 is fixedly connected to a U-shaped fixing rod 11. The two ends of the U-shaped fixing rod 11 are fixedly connected to the side of the annular block 16 through fixing rods.

[0021] As shown in the figure, the up-down moving mechanism includes a support plate 8 fixedly sleeved on the connecting rod 13, and two external electric telescopic rods 14 fixedly installed on the side of the moving ring 15. The output ends of the two external electric telescopic rods 14 are fixedly installed on the top of the support plate 8.

[0022] As shown in the figure, a connecting shaft 21 is fixedly installed on the side of the telescopic frame 22, and an inner ring 19 is fixedly installed on the other end of the connecting shaft 21. An annular rotating groove is provided on the inner wall of the annular groove, and the inner ring 19 is rotatably installed in the annular rotating groove.

[0023] As shown in the figure, the feed end of the pump 2 is connected to the inside of the feeding box 3.

[0024] As shown in the figure, a funnel 4 is fixedly installed at the top center of the dispensing box 3.

[0025] The working principle of this utility is as follows: When using the device, the user puts feed into the funnel 4, and the feed collects in the feeding box 3. The user then starts the suction pump 2 and the motor 12. The feed is conveyed through the suction hose 5, the fixed frame 18, and the telescopic frame 22 to the annular groove on the annular block 16. Initially, the moving ring 15 blocks the four sprinkling ports 17, so the feed cannot be thrown out. After a period of conveying, when a certain amount of feed is stored in the annular groove, the timer 6 starts the two external electric telescopic rods 14, which causes the moving ring 15 to move downward, thus allowing the four sprinkling ports 17 to leak out. The output shaft of the motor 12 rotates, causing the U-shaped fixed rod 11 to rotate. The rotation of the U-shaped fixed rod 11 drives the annular block 16 to rotate. Due to the centrifugal force, the feed is thrown out along the four sprinkling ports 17 to achieve the effect of sprinkling. This allows for spraying after a certain amount has been stored, and the sprinkling will not be uneven due to the fixed orientation of the suction hose 5.

[0026] When it is necessary to change the range of spreading, the internal electric telescopic rod 20 is activated, which drives the connecting rod 13 and the motor 12 to move downward and then upward. This causes the annular block 16 to move downward and then upward, thereby causing the positions of the four spreading ports 17 to move downward and then upward. The height of the spreading ports 17 changes, so that the feed falls in a parabolic trajectory, resulting in different areas where the feed falls, thus changing the feeding area.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
