Poultry breeding feed screening machine and screening method thereof

Abstract

The invention discloses a poultry breeding feed screening machine which comprises a bottom plate, vertical rods fixedly connected to the two sides of the top of the bottom plate and a bottom box fixedly connected to the top of the bottom plate through supporting legs, and supporting plates are fixedly connected between the tops and the bottoms of the opposite sides of the surfaces of the two vertical rods. The tops of the two supporting plates are fixedly connected with a top box and a middle box correspondingly, the bottoms of the inner walls of the top box, the bottom box and the middle boxare each provided with a material ejection assembly, and each material ejection assembly comprises a fixing cylinder. The invention relates to the technical field of breeding feed processing. According to the poultry breeding feed screening machine and the screening method thereof, three-stage screening of feed can be achieved on the same screening machine, large feed particles, medium feed particles and fine feed particles can be screened out respectively, devices of different specifications do not need to be used, the economic cost is reduced, meanwhile, feed blockage can be avoided during feed filtering through vibration screening of screening plates, meanwhile, the screening efficiency and quality are improved, and good conditions are created for subsequent feed production and processing.

Description

technical field [0001] The invention relates to the technical field of breeding feed processing, in particular to a poultry breeding feed screening machine and a screening method thereof. Background technique [0002] Feed is the general term for the food that everyone raises animals. In a narrower sense, general feed mainly refers to the food for raising animals in agriculture or pastoralism. Feed includes soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, Meat and bone meal, grains, feed additives and more than ten varieties of feed raw materials. [0003] Currently, when screening poultry breeding feed, a single device can only screen feeds of the same size and specification. If feeds of different specifications are to be screened, it is necessary to use multiple devices to complete the process, which undoubtedly increases unnecessary economic costs. , reducing work efficiency, and at the same time, when sieving feed, the feed is ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a poultry breeding feed screening machine and its screening method, which solves the problem that only feeds of the same size and specification can be screened inside a single device. When feeds of different specifications are to be screened, it is necessary to The use of multiple devices increases unnecessary economic costs and reduces work efficiency. At the same time, when sieving feed, the feed is easy to accumulate on the sieve plate, which will block the mesh and affect the follow-up normal screening work.
