Automatic straw pulverizer

Abstract

The invention discloses an automatic straw pulverizer, which comprises a frame, a draw rod, a front wheel and a rear wheel. The frame is provided with an engine, a fan, a gearbox and a pickup tool. One end of a spindle of the fan is in drive connection with the engine. The automatic straw pulverizer is characterized in that blades are uniformly distributed on a fan impeller; the frame is provided with a transverse delivery mechanism and a material clamping bin; an elastic compression roller and a supporting roller are arranged in the material clamping bin up and down; a plurality of feed rollers are arranged above the frame; the front parts of the feed rollers are provided with auger blades; the other end of the spindle of the fan is in drive connection with an input shaft end of the gearbox; the gearbox is provided with two output shaft ends; one end of the supporting roller is in drive connection with one output shaft end of the gearbox; a drive roller, the feed rollers and the elastic compression roller of the transverse delivery mechanism are respectively in drive connection with the other end of the supporting roller; and the other output shaft end of the gearbox is in drive connection with the pickup tool. The automatic straw pulverizer has the advantages that harvested straws which are stacked in the field can be picked up, pulverized and collected; and the working efficiency and the automation degree are high.

Description

technical field [0001] The invention belongs to an agricultural machine, in particular to an automatic straw grinder. Background technique [0002] The straw crusher is an agricultural machine that collects and crushes straw. CN20150444 discloses a fine shredder for picking up straw for returning to the field, including a frame, a suspension rod, a gearbox, a pick-up, a straw crushing wheel, a crushing wheel cover and a two-stage transmission belt, and the straw is placed along the circumferential direction on the rim of the straw crushing wheel. There are multiple rows of throwing knives evenly distributed. When it works, under the high-speed rotation of the straw crushing wheel, the long straw on the ground is secondarily crushed into short straw with a length of less than 1cm and returned to the field. This kind of straw picking fine crusher returns the crushed straw to the field, which is not conducive to re-cultivation of the field, but also because straw is a good cl...

Although the structure of this corn stalk harvesting and pulverizer is simple, the work efficiency is low. According to the cultivation sequence of the stalks, only one stalk can be harvested at a time. If multiple stalks are harvested at the same time, the stalks are easily stuck between the left and right sawtooth feed rollers. between, resulting in failure
