[0002] In the shrimp fry farming process, feed delivery is a key link. The traditional feed delivery method is mostly manual operation, which has many disadvantages.

[0003] Manual feeding is not only labor-intensive, but also requires farmers to operate at fixed times and locations, which consumes a lot of manpower and time. Moreover, it is difficult to achieve accurate feeding through manual operation, and the amount of feed is difficult to accurately control, which can easily lead to overfeeding or underfeeding. Overfeeding will lead to feed waste, and feed that is not eaten by the shrimp fry will remain in the breeding water, causing water pollution and affecting the growth environment of the shrimp fry; underfeeding cannot meet the growth needs of the shrimp fry, resulting in slow growth of the shrimp fry and even affecting its survival rate.

[0004] In addition, the traditional feeding method is also insufficient in terms of feeding uniformity. Shrimp seedlings in different areas may not get the same amount of feed, resulting in uneven growth of shrimp seedlings and affecting the overall breeding effect. At the same time, manual feeding is difficult to flexibly adjust according to the growth stage and actual needs of shrimp seedlings, and it is impossible to achieve scientific and accurate breeding management.

[0005] With the continuous expansion of aquaculture scale, the traditional manual feeding method can no longer meet the needs of modern shrimp fry farming. There is an urgent need for a device that can realize automatic, precise and uniform feeding to improve breeding efficiency, reduce costs, improve the breeding environment and ensure the healthy growth of shrimp fry.

[0029] During use, the material guiding ring 11 is fixed to the inner wall of the plastic floating pipe 1 in advance. The inner ring diameter of one end of the material guiding ring 11 close to the feeding port 17 is larger than the inner ring diameter of the other end of the material guiding ring 11. The two partitions 12 are respectively pushed into the two pipe orifices of the plastic floating pipe 1. The partition 12 is blocked by the corresponding material guiding ring 11. After the partition 12 contacts the material guiding ring 11, the screw rod 15 passes through the through hole 14, and the first nut 16 is screwed onto the screw rod 15 and tightened. At this time, the partition 12 is firmly fixed on one side of the material guiding ring 11. The material guiding ring 11 not only realizes the guiding of the feed stored between the two partitions 12 to the dispensing cylinder 21, but also serves as a connection and limiting structure for the partition 12, that is, the material guiding ring 11 has multiple functions. The feed is put into the storage space separated by the two partitions 12 inside the plastic floating pipe 1 from the feeding port 17, and then the cover 18 is inserted and screwed into the feeding port 17.

[0031] When in use, the control system of the electric push rod 24 and the servo motor 25 is programmed according to the feeding time, that is, the switches of the electric push rod 24 and the servo motor 25 are triggered at a fixed time. When feeding is required, the switch of the electric push rod 24 is triggered, and the electric push rod 24 pulls the plug plate 22 to quickly lift until the plug plate 22 pulls the bolt feed shaft 26 to drive the sealing plug 28 to be inserted into the discharge port 32. At this time, the plug plate 22 is pulled away from the barrel mouth of the dispensing barrel 21, and the private chat inside the plastic floating tube 1 slides to the dispensing barrel 21. The switch of the electric push rod 24 is then triggered to push the plug plate 22 down and insert it into the mouth of the filling tube 21, and then the switch of the servo motor 25 is triggered.
