Grass and tree crushing and cutting device

Abstract

The invention discloses a grass and tree crushing and cutting device. The grass and tree crushing and cutting device comprises a support, a crushing and cutting part and a driving part, the crushing and cutting part comprises two crushing and cutting mechanisms, the two crushing and cutting mechanisms are arranged on the support in parallel at an interval, and the two crushing and cutting mechanisms can act at the same time to cut grass and trees into fixed lengths; and the driving part is arranged on the support and drives the two crushing and cutting mechanisms at the same time, so that thecrushing and cutting mechanisms act at the same time to cut off the grass and trees. The two crushing and cutting mechanisms can be used for chopping the grass and trees into the fixed lengths, the same driving mechanism is used for driving the two crushing and cutting mechanisms at the same time to enable crushing and cutting to be synchronous, and the distance between the two crushing and cutting mechanisms is the fixed length of the chopped grass and trees, so that the crushing and cutting efficiency is improved, the length accuracy is improved, the length of a filtering material is proper,and the filtering efficiency and the filtering effect are considered at the same time.

Description

technical field [0001] The invention relates to the field of filter material preparation, in particular to a vegetation chopping device. Background technique [0002] Textile printing and dyeing wastewater mainly contains dirt, grease, salts on textile fibers, and various slurries, dyes, surfactants, auxiliaries, acids and alkalis added during processing. The wastewater is characterized by high concentration of organic matter, complex components, The chroma is deep and changeable, the pH changes greatly, and the water quantity and quality change greatly. It is a difficult-to-treat industrial wastewater. In the process of wastewater treatment in suburban or district / county factories, natural weeds, crop stalks, shrubs, tree branches, etc. are often used as filter materials. These filter materials are naturally pollution-free, low in cost, and have a wide range of sources. They can also be used as other raw materials after being dried as filter materials. [0003] The filter...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention proposes a vegetation chopping device to solve the problem that the existing chopping equipment proposed in the above-mentioned background technology needs to artificially control the cutting length, not only the chopping efficiency is low, but also the length is difficult to control accurately , It is easy to have different lengths, which will affect the filtration efficiency and filtration effect.
