Crushing equipment used for fish feed with particle size adjustable function

Abstract

The invention provides crushing equipment used for fish feed with a particle size adjustable function. The crushing equipment used for the fish feed with the particle size adjustable function comprises a shell body. A filter screen is fixedly connected on the inner side wall of the shell body and the filter screen is in a circular-arc shape. A first sleeve barrel is fixedly connected in the middleof the upper side of the filter screen and a plurality of second crushing teeth are uniformly arranged on the outer side wall of the first sleeve barrel. A plurality of through holes are formed in the side wall of the bottom of the first sleeve barrel and a first rotary shaft is arranged in the first sleeve barrel. The first rotary shaft is vertically arranged and passes through the upper portionof the shell body and extends upward. The top end of the first rotary shaft is fixedly connected with an output shaft of a first motor which is located at the upper side of the shell body and a spiral auger is arranged on the first rotary shaft. The crushing equipment has the beneficial effects that the first motor drives the first rotary shaft to rotate and the spiral auger on the first rotary shaft drives materials to move upward, so that the crushing retreatment can be conducted; the first rotary shaft drives a second sleeve barrel to rotate by circular plates and the crushing retreatmentcan be conducted on the materials by first crushing teeth and the second crushing teeth.

Description

technical field [0001] The invention relates to the technical field of fish feed processing, in particular to a crushing equipment for fish feed with the function of adjustable crushing particle size. Background technique [0002] With the development of aquaculture industry, fish feed with simple production methods, low ingredients and good feeding effect is more and more popular. However, the feed used for raising fish belongs to special feed, and the crushed particle size of the feed is required to be relatively fine. At the same time, it must be able to provide various nutrients needed for fish growth. [0003] At present, the feed for aquaculture fish is either simply crushed manually or crushed by purchasing a grinder. Manual crushing is not only low in crushing efficiency, but also unsatisfactory in crushing effect. , increasing the quality and linear speed of the crushing cutter head, thus increasing the power consumption, and the equipment is easy to wear; in addit...

Problems solved by technology

[0003] At present, the feed for aquaculture fish is either simply crushed manually or crushed by purchasing a grinder. Manual crushing is not only low in crushing efficiency, but also unsatisfactory in crushing effect. , increasing the quality and linear speed of the crushing cutter head, thus increasing the power consumption, and the equipment is easy to wear; in addition, fish have different requirements for feed particle size in different growth stages, while the existing feed crushing The particle size of machine crushing cannot be adjusted
