Automatic feeding and crushing device

Abstract

The invention discloses an automatic feeding and crushing device which comprises a rack, a crushing device, a feeding device and a crushed powder collecting device. The feeding device is composed of a feed bin, an anti-winding feed drum, an upper feed inlet baffle and a horizontal feed tray; the crushing device comprises a crushing bin and a crushing blade installed in the crushing bin, the crushing blade comprises a center shaft sleeve and three blade bodies evenly arranged on the outer side face of the center shaft sleeve, and the three blade bodies and the center shaft sleeve are combined into a Y-shaped moving blade body; V-shaped rubber material pushing plates are evenly distributed on the anti-winding feed drum; the crushed power collecting device is composed of a draught fan, a reversing device which is composed of a three-way pipe and a reversing plate arranged in the three-way pipe and a pair of powder accumulators connected through the reversing device. The automatic feeding and crushing device is simple, practical and easy to popularize, and therefore obvious economical benefit and social benefit can be generated; the crushing blade adopts the Y-shaped moving blade body, and therefore the crushing cutting efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an automatic feeding crushing device. Background technique [0002] In rural areas, a large amount of crop straw is produced every year, such as wheat straw, corn stalk, bean stalk, firewood and other crop waste stalks. The crushed powder can be used to make various raw materials such as organic fertilizer, fuel, paper, etc., turning waste into treasure , while creating economic value, it also protects the environment. However, the currently used straw grinder does not feed smoothly, and the material is easily blocked at the feed inlet, making it impossible to continue feeding, so that it must be shut down for cleaning, resulting in a work stoppage. In addition, it is difficult to collect the crushed powder. The labor intensity is high, the work efficiency is low, and the demand of the market cannot be met. And the pulverizer blade of prior art is mostly sheet-like structure,...

Problems solved by technology

However, the currently used straw grinder does not feed smoothly, and the material is easily blocked at the feed inlet, making it impossible to continue feeding, so that it must be shut down for cleaning, resulting in a work stoppage. In addition, it is difficult to collect the crushed powder. High labor intensity, low work efficiency, unable to meet market demand

And the pulverizer blade of prior art is mostly sheet-like structure, and it is installed on the roller by the hole of one end, and it has the cutting force of a rotation direction so as to realize cutting object when roller forward rotation, but when roller reverses When the direction is turned, it is impossible to achieve the purpose of crushing, and the blade structure of the prior art pulverizer is relatively single, which cannot achieve a good cutting purpose, and the applicability is limited to a certain extent
