An automatic feeding device for large yellow croaker feed

Abstract

The invention discloses a large yellow croaker feed automatic feeding device. The device comprises a base, a battery and a hydraulic station are fixed at the upper end of the base, and a horizontal hydraulic cylinder is fixed at the upper end of the base; a vertical rod is fixed to the edge of a hydraulic rod of the hydraulic cylinder, and a rib plate is fixed between the vertical rod and the hydraulic rod of the hydraulic cylinder; an electromagnet is fixed at the upper end of the vertical rod, a support A is fixed at the upper end of the base, and a horizontal steel tube is fixed at the upper end of the support A; a stop block is fixed at the upper end of an inner ring of the steel tube, and a piston connected with the steel tube in a sliding mode is arranged in the steel tube; a rubberblock is fixed to the side, close to the stop block, of the piston. According to the device, fish feed falling is accelerated through a vibrator, the falling speed of fish feed is ensured, the feedingspeed of the fish feed is ensured, and the feeding efficiency is improved; through continuous movement of the hydraulic cylinder and the electromagnet, enough thrust force is ensured so that the fishfeed can reach a designated position, operation of a breeder is facilitated, and convenience is brought to the breeder.

Description

technical field

[0001] The invention relates to the field of breeding industry, in particular to an automatic feed feeding device for large yellow croaker. Background technique

[0002] In fish farm feeding technology, how to feed automatically reasonably and effectively is an important research link. Most of the traditional fish feeding is artificial feeding, but artificial feeding is only suitable for small fish ponds. With the increase in the demand for fish, the fish breeding site is gradually expanding, so it is replaced by automatic feeding. Manual feeding is inevitable, and automatic feeding can save a lot of manpower. Most of the current automatic feed feeding devices use vibration feeding or directional feeding. These two feeding machines are installed on the water surface of the fishery, and the area for throwing feed is small, the feed is relatively concentrated, and the feed powdering rate is high. It will lead to uneven feeding of fish schools, which is not co...
