Problems solved by technology

[0003] The cutting tool and cutter head of the existing straw shredder are combined by welding, so when a few teeth in the cutter are damaged, the cutter and the cutter head need to be completely replaced, resulting in unnecessary waste
The straw grinder adopts a uniform tooth shape cutter, and the single tooth shape cutter makes the processing process, due to the inconsistent shape of the straw, resulting in uneven particle size of the crushed particles.
[0004] Moreover, the straw grinder is not equipped with a closed negative pressure suction device, which makes the processed straw particles scattered in the air, causing great dust pollution to the environment.

Abstract

The invention discloses a straw pulverizing method, which adopts a hammer-type straw pulverizer, and comprises the steps of: S1, putting the straw into the hammer-type straw pulverizer; S2, pulverizing the straw by the hammer-type straw pulverizer, Forming granular materials; S3, bagging the materials; wherein, in step S2, a negative pressure is generated by the suction device of the hammer-type straw grinder, so that the materials enter the discharge hopper. The straw crushing method of the present invention adopts a hammer-type straw crushing machine with a negative pressure device, which can directly suck the crushed particles into the collecting device through the suction of the air, so as to ensure smooth material flow and improve the working efficiency of straw crushing , and can well avoid the phenomenon of dust flying.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular, the invention relates to a straw crushing method. Background technique [0002] Straw is rich in energy. In recent years, due to measures such as on-site incineration or landfilling, most of the straw has been wasted, resulting in the inability to fully utilize the energy in straw. In China, the utilization rate of feed energy for straw is less than 10%. %, while incineration and other measures have also caused great damage to the environment. Therefore, the biomass energy contained in straw is still worthy of our research and exploration, which puts forward new requirements for the processing and utilization of straw. In the early stage of grinding process, it is necessary to develop and utilize the corresponding biomass raw materials. Only when the biomass particles reach a certain size and requirements can adequate preparations be made for the subsequent research...
