An automatic crushing device for preparing grain raw materials for poultry feed

Abstract

The invention relates to the technical field of feed processing, and specifically proposes an automatic crushing device for preparing grain raw materials for poultry feed. The device includes a casing, an inner lining plate and a crushing mechanism; the inner lining plate is U-shaped and fixed on the casing In the medium crushing operation area, the crushing mechanism is assembled in the casing and is located above the inner lining plate; the device provided by the invention solves the problem of the existing hammer mills with a single hammer blowing method, There are many problems such as poor material initiative, poor material accumulation fluidity, and blockage of screen holes, which affect the timely discharge of crushed materials.

Description

technical field [0001] The invention relates to the technical field of feed processing, and specifically provides an automatic crushing device for preparing grain raw materials from poultry feed. Background technique [0002] In the process of poultry breeding, the feed nutrients required at different growth stages are different. In order to coordinate with the poultry growth process for scientific feeding, it is necessary to produce and prepare poultry feed required for different growth cycles of poultry, so that the prepared poultry feed contains All the nutrients poultry need to grow. Grain raw materials are generally the main source of raw materials for poultry feed. Grain raw materials mainly include corn, soybeans, bran, etc. In order to prepare poultry feed containing required nutrients, it is usually necessary to grind each grain raw material, and then The crushed different grain raw materials are re-mixed according to the scientific ratio and processed into compoun...

Problems solved by technology

[0003] For the crushing of grain raw materials, hammer feed mills are mainly used for crushing and processing. The hammer part is driven by the rotor part to rotate quickly, so that the grain raw materials are hammered and crushed by hammers. However, the existing hammer mill There are the following problems: (1), the hammer blades of the existing hammer mills do not have the effect of reciprocating and striking materials in the radial direction during the rotating and crushing process, and completely rely on the rotation to drive the materials, so the way of crushing and striking materials is single , poor initiative

[0004] (2) The existing hammer mills are basically only equipped with hammers. When the grain raw materials are put in, they need to rely on the hammers to drive the materials to flow passively. The flow effect of the materials is poor, and the accumulation in the crushing bin is Materials outside the impact range of the hammer are not easily crushed by the hammer, so the overall crushing effect is poor and the crushing efficiency is low

[0005] (3) Existing hammer mills have a certain degree of sieve blockage when crushing materials, and when the moisture content of grain raw materials is high, the plugging phenomenon will increase, affecting the quality of the crushed materials. Discharge in time, and then affect the crushing efficiency

[0006] (4) The hammer of the existing hammer mill is a thin plate structure, which has a small crushing contact surface with the material, so the crushing efficiency is low
