Agricultural straw crushing, screening and drying device

Abstract

The invention relates to an agricultural straw crushing, screening and drying device which comprises a feeding cylinder, a crushing box, a straw crushing device, a screening and scraping device, a semicircular screening cylinder, a damping and supporting device and a discharging and drying device. The feeding cylinder is welded at the center of the upper end wall of the crushing box, the crushingbox is welded at the upper end of a guide cover, a crushing device is arranged on the side wall of the crushing box, the semicircular screening cylinder is obliquely welded on the inner wall of the crushing box and arranged at the left end of the screening and scraping device, the right end of the screening and scraping device is connected with a coupler through a third bearing, the damping and supporting device is welded at the upper end of the discharging and drying device, and the discharging and drying device is welded on a supporting frame. According to the device, crushing and drying areintegrated, straws are crushed, screened and crushed again, the crushing effect of the straws is ensured, drying is performed in the overturning and discharging process, the heated area of the strawsis ensured, and the drying efficiency is improved.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to an agricultural straw crushing, screening and drying equipment. Background technique [0002] Agricultural production will produce a large amount of straw, and straw incineration will cause a lot of pollution. The reuse of straw has become an important issue at present; now there is a process of making fuel from straw into bricks, which can solve this problem, but the straw needs to be crushed and dried before being pressed into bricks. The existing crushing and drying device does not crush thoroughly, causing unnecessary troubles to the brick pressing process; most of the straw is not dry and needs to be dried, which cannot be satisfied by the existing device; the crushing, stirring and drying process is scattered and the efficiency is low. Contents of the invention [0003] In view of the above situation, it is necessary to provide a straw processing equipment with integrated crus...

The reuse of straw has become an important issue at present; now there is a process of making fuel from straw into bricks, which can solve this problem, but the straw needs to be crushed and dried before being pressed into bricks. The existing crushing and drying device is not completely crushed, causing unnecessary troubles to the brick pressing process; most of the straw is not dry and needs to be dried, which cannot be satisfied by the existing device; the crushing, stirring and drying process is scattered and the efficiency is low
