Biomass straw crushing and briquetting integrated device

Abstract

The invention discloses a biomass straw crushing and briquetting integrated device, and relates to the technical field of agricultural equipment. The device comprises a feeding pipe, a box body, a crushing chamber and a briquetting chamber, wherein one outer side surface of the box body is fixedly connected with the feeding pipe; the crushing chamber and the briquetting chamber are arranged in thebox body; the crushing chamber is positioned above the briquetting chamber; and supporting legs are arranged at the bottom of the box body. By means of arrangement of conveying rotating wheels, firstcutting blades, second cutting blades, first crushing blades and second crushing blades, multiple crushing steps are conducted in sequence, so that the device can adapt to biomass straw with different hardness, the biomass straw is crushed more sufficiently, meanwhile, the crushing process is conducted in the box body, and dust is prevented from flying outwards and polluting the environment; andthe briquetting chamber is arranged below the crushing chamber, and a discharging chamber is tightly connected to the outer side of the briquetting chamber, therefore, briquetting and discharging arecompleted in one step, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, in particular to an integrated device for crushing and briquetting biomass straw. Background technique [0002] China is a large agricultural country. According to the latest statistics, as of 2016, the sown area of ​​crops in my country has reached 160 million hectares, and the annual biomass output has exceeded 700 million tons. The traditional farming method of biological straw is generally burned on the spot, which not only pollutes the environment and aggravates global warming, but also reduces the organic matter of the land and causes waste of resources. Biomass straw has the problems of light specific gravity, large volume, and low density, which are difficult to transport, and the storage and transportation costs of biomass straw raw materials are relatively high; if the crop straw can be crushed or chopped and then mechanically compressed into fuel blocks, not only It can...

Problems solved by technology

[0004] The object of the present invention is to provide an integrated device for crushing and briquetting biomass straws. By setting a feed pipe, a box body, a crushing chamber and a briquetting chamber, the existing straw crushing device has no effect on the crushing of biomass straws. Well, the pulverizer is separated from the briquetting machine, and the straw cannot be crushed and briquetted efficiently and quickly.
