The chaff crushing device that can ensure the even feeding of the chaff

Abstract

The invention provides a chaff crushing device capable of ensuring uniform blanking of chaff. The chaff crushing device comprises a material storage device, a material distribution device and a crushing device, wherein an outlet of the material storage device is communicated with an inlet of the material distribution device; an outlet of the material distribution device is communicated with an inlet of the crushing device; the material distribution device comprises a material distribution roller; the material distribution roller comprises a middle shaft, a partition plate and baffle plates; the partition plate is divided into end partition plates at two ends and a middle partition plate; the end partition plates are fixed at two ends of the middle shaft respectively; the partition plates are evenly distributed along the length direction of the middle shaft and are fixed on the middle shaft; the baffle plates are arranged between the two partition plates; the bottom edges of the baffle plates are fixed on the middle shaft; two sides of each baffle plate are fixed to the partition plates at two sides respectively; the baffle plates are evenly arranged around the middle shaft in a rotating manner; the baffle plates at two sides of the partition plate are arranged in a staggered manner; dense chaff or hollow cavities are further scattered by the partition plates and the baffle plates; and the condition that the materials dropping into the crushing device are relatively evenly dispersed are ensured by small spares which are arranged in a staggered manner, so that the crushing machine can stably work for a long period of time; and the efficiency is significantly improved.

Description

technical field [0001] The invention relates to a chaff crushing device, in particular to a chaff crushing device capable of ensuring uniform feeding of chaff. Background technique [0002] Because the chaff itself is relatively light and small, and its fluidity is very poor, the chaff in the storage bin is unevenly distributed, some places are clumped, and some places are cavities. During the crushing process, the chaff in the storage bin enters the crusher. It is also not uniform, sometimes the dense chaff enters the grinder, sometimes it is a hole, and nothing enters the grinder. This uneven material causes the current of the grinder to be unstable, and it is severely worn, and often occurs Faults, frequent repairs, time-consuming and labor-intensive delays in production. [0003] In the prior art, a material distribution device is installed between the storage bin and the pulverizer, such as the roller distributor of CN103404674B, but the above-mentioned roller distribu...

[0002] Because the chaff itself is relatively light and small, and its fluidity is very poor, the chaff in the storage bin is unevenly distributed, some places are clumped, and some places are cavities. During the crushing process, the chaff in the storage bin enters the crusher. It is also not uniform, sometimes the dense chaff enters the grinder, sometimes it is a hole, and nothing enters the grinder. This uneven material causes the current of the grinder to be unstable, and it is severely worn, and often occurs Faults, frequent repairs, time-consuming and labor-intensive, delays in production

[0003] In the prior art, a material distribution device is installed between the storage bin and the pulverizer, such as the roller distributor of CN103404674B, but the above-mentioned roller distributor is applied to the crushing of rice husks, and a strip of space formed by each material distribution plate remains the same. There is a situation where part of the chaff is dense and part of it is empty, which still cannot solve the problem of uneven cutting of chaff
