Crushing and screening device for feed grease processing

Abstract

The invention relates to the technical field of feed grease processing, in particular to a crushing and screening device for feed grease processing. The crushing and screening device comprises an outer tube; a crushing tube is arranged in the outer tube, and an adding hopper is arranged at the top end of the crushing tube; two parallelly-arranged rotating rods are arranged in the crushing tube, wherein the outer wall of an internal section, in the crushing tube, of one of the rotating rods is provided with first flail knives which are distributed at equal distances, and the outer wall of an internal section, in the crushing tube, of the other rotating rod is provided with second flail knives which are distributed at equal distances; and the tail ends of the rotating rods extend outside theouter tube and are connected with a motor. By starting the motor, a transmission rod is driven by an output shat of the motor to rotate and drives a sleeve to rotate, the sleeve drives a base to rotate through a spring, the base drives a homogenizing plate to rotate along the end face on a screen net, the homogenizing plate can spread out crushed materials at the upper end of the screen net, quick screening of the crushed materials is convenient, and the screening efficiency of the crushed materials is greatly improved.

Description

technical field [0001] The invention relates to the technical field of feed oil processing, in particular to a crushing and screening device for feed oil processing. Background technique [0002] In the process of feed processing, adding oil to the feed can increase the energy of the feed, promote the absorption of fat-soluble vitamins and pigments, accelerate the growth of animals, and reduce animal diseases. The appearance of feed products and the feed production process are closely related to the amount of fat added. [0003] After searching, the patent with the publication number CN206746757U discloses a crushing and screening device for feed granulation, which includes a shell and a particle crushing mechanism, a first screening mechanism, and a first screening mechanism that are sequentially arranged inside the shell from top to bottom. Mechanism, the second screening mechanism, the third screening mechanism, the top of the shell is provided with a feed inlet, the bot...
