Screening processing system for production of pig feed

Abstract

The invention relates to a screening processing system for production of pig feed. The screening processing system comprises a supporting device and a screening net, wherein the screening net is arranged at the top of the supporting device; the screening net comprises a lower screening net body and an upper screening net body which is slidably arranged at the top of the lower screening net body; an-shaped frame is arranged at a position, close to the edge, of the top of the upper screening net body; and a shaking device is arranged at the bottom of the supporting device. According to the screening processing system provided by the invention, by arranging two groups of screening nets moving relatively, the two groups of screening nets are staggered, the overlapped areas of the meshes are changed, the size of the meshes of the screening nets is changed, the application range is wider, and the two groups of screening nets can be pulled to move simultaneously through cooperation of a pullrope and a fixed pulley. According to the screening processing system provided by the invention, a cam is driven to rotate by a rotating shaft; one end of the supporting device ascends and descends in a reciprocating mode and at the same height; the shaking force is kept constant during screening of the feed; and the feed is prevented from scattering down from the screening nets in cooperation with the n-shaped frame on the upper screening net.

Description

technical field [0001] The invention relates to the technical field of feed screening, in particular to a screening and processing system for pig feed production. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. The feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives and more than ten varieties of feed materials. Adulterated feed is generally finely ground, with no visible components, darker or lighter in color, often deliquescent, moldy, moth-eaten, lumpy due to high moisture content, and sometimes mixed with a large amount of sand or a large amount of low-cost feed . When distinguishing whether the feed is inferior feed, in addition to the sensory identification, it can also be identified by sieving, specifically: ...

AI Technical Summary

Problems solved by technology

[0003] The existing screening equipment has the following disadvantages: 1. The diameter of the sieve mesh is fixed and cannot be adjusted, and the scope of application is limited; 2. During manual sieving, the feed will spill from the sieve due to uneven shaking force
