Upcut hammer mill

Abstract

The invention provides an upcut hammer mill. The upcut hammer mill comprises a milling chamber, motors, belt pulleys and a rack and further comprises an upcut chamber. The upcut chamber comprises a feed port, upcut knives and an upcut knife shaft. The milling chamber comprises arc-shaped rails, a rubbing plate, knife rests, spacer bushes, a stationary knife, hammer knives, hammer knife shafts and a knife rest spindle. The upcut knife shaft penetrates the upcut chamber to be in transmission connection with the second motor at the bottom. An upper cavity and a lower cavity of the milling chamber are connected through a bolt. The whole cavity is fixedly arranged on a milling chamber rack through the knife rest spindle. The arc-shaped rails and the rubbing plate are fixedly arranged in the upper cavity and the lower cavity. The four hammer knife shafts are evenly distributed on the knife rests. The hammer knives are spaced by the spacer bushes, two sets of hammer knives are distributed alternately, every two adjacent sets of hammer knives are symmetrically arranged in a staggered manner, and materials of different particle sizes can be obtained by replacing rubbing plates with meshes of different sizes. Procedures are reduced to the maximum degree, the upcut chamber is creatively designed to be separated from the milling chamber, and traditional hammer milling is ingeniously benefited; and energy consumption is reduced, operation is convenient, and labor intensity is reduced.

Description

technical field [0001] The invention belongs to the improvement of the straw crushing machine in the agricultural machinery, and in particular relates to an upper-cut hammer mill. Background technique [0002] How to rationally utilize the crop straw produced in the farmland has become an urgent problem to be solved. The utilization of straw is mainly in two aspects: one is to be used as industrial raw materials such as biomass energy, biogas engineering, and papermaking, which requires the material to be soft and finely divided, which is more conducive to post-processing such as fermentation and compression molding, and improves production efficiency and quality. The other part is used as livestock feed, and the crushed material is required to be soft, finely crushed, and palatable, so that it is easier for livestock to chew, and it solves the problem of excessive energy consumption of ruminants such as cattle and sheep when eating, and also solves the problem of It reduce...

AI Technical Summary

Problems solved by technology

Most of the existing straw shredders on the market cut and crush on the same drive shaft, resulting in poor feeding of straw and low production efficiency. It is possible that the cut part of the straw will pop up and hurt people easily. The output is low and the energy consumption is large. Long material straw such as straw needs cutting, chipping and other auxiliary machinery to carry out the cutting process
