Tree branch pulverizer

Abstract

The invention discloses a tree branch pulverizer, comprising a feed hopper, a pulverizing unit, a crushing unit and a material suction unit, wherein the feed hopper is communicated with the pulverizing unit, the pulverizing unit is communicated with the crushing unit, the crushing unit is connected with the material suction unit through an air suction pipe, one end of the crushing unit connected to the air suction pipe is provided with a suction ventilator, and one end of the crushing unit connected to the material suction unit is provided with a discharge hopper; the crushing unit comprising a crushing chamber, the crushing chamber is a cylinder and arranged horizontally, the top of the cylinder is provided with a filter screen, the filter screen is fixed on a discharge flange, the discharge flange covers the surface of the filter screen, the meshes of the filter screen is circular, the diameters of the meshes are 15-20mm, and the discharge flange is connected with the suction ventilator. According to the invention, the design is ingenious, by arranging the filter screen on the crushing chamber, high-quality pulverized tree branch particles can be acquired, low working efficiency due to that halfway pulverization of the tree branches blocks the suction ventilator can be avoided, the pulverizer is improved, the cost is low, and the pulverizer disclosed herein can be widely suitable for pulverization of all tree branches.

Description

technical field [0001] The invention relates to the field of pulverizing machinery, in particular to the technical field of a branch pulverizer capable of pulverizing vegetation. Background technique [0002] With the increasing environmental awareness of people, the requirements for the environment are getting higher and higher, and the random stacking and burning of discarded branches and fallen leaves in the city is gradually banned. . The main technical scheme that adopts at present is to be used as base fertilizer for urban vegetation, potted flowers and saplings transplanting through natural fermentation and decay after the branches and fallen leaves are crushed. Therefore, some domestic manufacturers and scientific research institutions have begun to independently research and develop, using branches to be transported into the pulverizer, and the branches are cut into small pieces by a number of knives arranged on the rotating knife seat. However, due to the differe...

AI Technical Summary

Problems solved by technology

However, due to the different thicknesses of the crushed branches, the devices used to cut different branches are also different on the shredder, and most of the branch shredders currently used by people can only cut some small branches, and for thick branches, it needs to be processed. It can only be crushed by a pulverizer after decomposition, which is very inconvenient

Moreover, the size of the crushed branches is uneven, or the crushing is not thorough enough, which affects the natural fermentation time, and the fertility of the base fertilizer will also be weakened.

At present, there are still some pulverizers imported from abroad on the market, which are not only expensive, but also inconvenient for machine maintenance and parts replacement, which affects the wide application of this technology
