A feed feeding device for aquaculture

Abstract

The invention relates to an aquaculture feed feeding device, and discloses a device which determines a feeding region through depth detection and throws out feed through centrifugal force generated incooperation with rotation of a spiral channel for feed feeding. The device is characterized in that a water permeable cover is arranged on an opening of a material containing cylinder, a plurality ofwater permeable holes are formed in the water permeable cover, the middle of the material containing cylinder is wide, the two ends of the material containing cylinder are narrow, a storage cavity isformed inside the material containing cylinder, the spiral channel is formed in the bottom of the material containing cylinder and communicated with the storage cavity, the upper end of the spiral channel is an inlet, the lower end of the spiral channel is an outlet, a plurality of spiral blades are arranged on the outer side of the material containing cylinder at equal intervals, a plurality ofwater absorbing holes are formed in the outer side of the material containing cylinder at equal intervals and located in one sides of the multiple spiral blades in a one-to-one corresponding mode, thewater absorbing holes are formed in the portion, with the largest diameter, of the cross section of the material containing cylinder, inlets of the water absorbing holes are wide, and outlets of thewater absorbing holes are narrow; the distance between the axis of a connecting shaft and the water absorbing holes is larger than that between the inlet of the spiral channel and the axis of the connecting shaft, and the spiral blades are formed by one-time punch forming of metal materials.

Description

technical field [0001] The invention relates to an aquaculture feed feeding device, which relates to a device used in aquaculture for feeding aquaculture feed, and belongs to the field of aquaculture. In particular, it relates to a device for determining the feeding area through depth detection and throwing out the feed in cooperation with the centrifugal force generated by the rotation of the spiral channel for feeding. Background technique [0002] At present, in the aquaculture industry, people often carry out aquaculture such as fish and shrimp in lakes, reservoirs and shallow seas. According to different living habits, the aquatic products can be divided into upper, middle and bottom waters. Common species include silver carp, grass carp, crucian carp, and catfish. When feeding aquatic products in aquaculture waters, the traditional feeding method is to row on the water surface in a small boat, throw the feed by hand or use a wooden The shovel and other tools throw the...

[0002] At present, in the aquaculture industry, people often carry out aquaculture such as fish and shrimp in lakes, reservoirs and shallow seas. According to different living habits, the aquatic products can be divided into upper, middle and bottom waters. Common species include silver carp, grass carp, crucian carp, and catfish. When feeding aquatic products in aquaculture waters, the traditional feeding method is to row on the water surface in a small boat, throw the feed by hand or use a wooden The shovel and other tools throw the feed onto the water surface, let the feed sink naturally, and complete the feed feeding. With this feeding method, after the feed falls into the water and reaches the middle and lower waters of aquatic activities, part of the feed will be dissolved by the water and cannot Ingested by middle and bottom aquatic products, resulting in a waste of resources, and the feed is fed by throwing, the amount of thrown feed decreases with the distance, and the amount of feed near the breeder is relatively large, resulting in insufficient feeding Uniformity, and the throwing action requires greater arm strength of the breeder. Long-term operation is prone to muscle strain. When the thrown feed enters the water, the sound is loud, which is easy to disturb the fish and is not conducive to its growth. The existing aquaculture feed The feeding device, such as the publication number CN206324026U, discloses a feeding device for aquatic feed. The device floats on the water surface. When feeding mid-bottom aquatic feed, the feed is easily dissolved before falling into the predetermined area, resulting in waste of resources, and the device cannot detect the depth of the water area where the feed is fed, and cannot select the best feed water depth area for feed feeding, and the use effect is not good
