Problems solved by technology

[0003] In the existing straw shredder, the cutter and the cutter head 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.

Embodiment Construction

[0029] The following describes the specific implementation of the present invention in further detail through the description of the embodiments with reference to the accompanying drawings. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and Contribute to its implementation.

[0030] Such as figure 1 As shown, the present invention provides a hammer-type straw pulverizer, which includes a frame 2, a power device, a main shaft, a cover (not shown in the figure), a pulverizing chamber 7, and a pulverizing chamber 7 rotatably arranged in the pulverizing chamber 7. The hammer holder 3, the first crushing tool 4, the second crushing tool 10, the first crushing tool 4 and the hammer holder 3 form a detachable connection, and the first crushing tool 4 and the hammer holder 3 are kept facing each other during operation A fixed first quick-change device 5 and a second...

Abstract

The invention discloses a hammer-type straw pulverizer, comprising a pulverizing chamber, a hammer rack rotationally arranged in the pulverizing chamber, a first pulverizing tool, a second pulverizingtool and a first quick change device allowing the first pulverizing tool to be releasably connected with the hammer rack and allowing the first pulverizing tool and the hammer rack to be relatively fixed when operating. The hammer-type straw pulverizer has the advantages that the pulverizing tools are convenient to change, so that tool changing efficiency is greatly improved; a vacuum device is used, pulverized particles can be sucked directly into a collecting device under air suction effect, and dusting can be well avoided.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment. Specifically, the invention relates to a hammer-type straw pulverizer. Background technique [0002] Straw is rich in energy. In recent years, most of the straw has been wasted due to measures such as on-site incineration or landfilling, resulting in the inability to make full use of the energy in the straw. In China, the utilization rate of feed energy to straw is less than 10%. %, and measures such as incineration 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 the 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 the subsequent research and utilizat...
