Crude stalk chopper capable of automatically adjusting feeding height

Abstract

The invention discloses a crude stalk chopper capable of automatically adjusting the feeding height, which comprises a chopper component, a feeding mechanism (4) and the like. The chopper component comprises a chopper shell (2), a movable tool holder (8), a movable blade (9), a hammer leaf (14) and a fixed blade (10) which are arranged in the chopper shell (2), wherein the fixed blade (10) is fixedly connected with a rack (7), the movable blade (9) and the hammer leaf (14) are both fixedly connected with the movable tool holder (8), the movable tool holder (8) is connected with a power shaft (51), and the power shaft (51) is connected with a motor (6) through a belt transmission case (5); a throwing device (1) which is arranged above the chopper shell (2) is communicated with the outlet of the chopper shell (2); a feeding trough (3) is communicated with the inlet of the feeding mechanism (4), and the outlet of the feeding mechanism (4) is communicated with the inlet of the chopper shell (2). The chopper is applicable to the chopping of cotton stalks, mulberry twigs and other kinds of crude stalks.

Description

technical field [0001] The invention relates to a thick and hard stalk chopping device capable of automatically adjusting the feeding height, and belongs to the technical field of agricultural machinery. Background technique [0002] After the crop straw is chopped, it is mechanically compressed to produce rod-shaped, block-shaped or granular fuel, which can replace coal, fuel oil, liquefied petroleum gas, etc., and is widely used in household heating, domestic stoves, hot water boilers, industrial boilers and biomass power plants Wait. The straw choppers or pulverizers that have been developed in China are mostly used for crushing and returning to the field or for cutting feed. The particle size of the chopped straw generally cannot meet the requirements of biomass compression molding. The chopped materials need to be screened multiple times. Increased production costs. In addition, the existing straw shredders are mainly aimed at shredding soft stalks such as rice straw ...

Problems solved by technology

The straw choppers or pulverizers that have been developed in China are mostly used for crushing and returning to the field or for cutting feed. The particle size of the chopped straw generally cannot meet the requirements of biomass compression molding. The chopped materials need to be screened multiple times. increased production costs

In addition, the existing straw shredders are mainly aimed at shredding soft stalks such as rice straw and wheat straw, while for thick and hard stalks such as cotton stalks and mulberry branches with dense tissue structure and high degree of lignification, the cutting The cutting strength is much higher than that of soft stems such as rice straw and wheat straw, and there is still a lack of corresponding shredding equipment to choose
