Straw crusher with composite cutter roller

Abstract

The invention discloses a straw crusher with a composite cutter roller. The straw crusher comprises a machine frame and a suspension cover; two ends of the suspension cover are opened; the suspensioncover is provided with a wheel shaft in the width direction, two ends of the wheel shaft penetrate through side plates at two sides of the suspension cover; the two ends of the wheel shaft are provided with ground wheels; a cutter roller is rotatably arranged inside the suspension cover; blades are arranged on the cutter roller; a motor for driving the cutter roller to rotate is arranged on the machine frame; the blades comprise fixed blades and swinging blades; the fixed blades and the swinging blades are distributed along the circumferential direction of the cutter roller in a staggered way;each fixed blade comprises a vertical cutting part and a transverse cutting part which are integrally formed; the rear end of the machine frame is connected with a handle; the tail end of the handleis provided with a power supply connection port and a power switch; and the handle is internally provided with a wire connecting the power supply connection port and the motor. The cutter roller structure is novel; the crushing efficiency can be improved; the whole weight of the crusher is reduced; the flexible movement control can be carried out through manual pushing, so that the crusher is moresuitable for single-person straw crushing operation in hilly land areas; the integral structure of the crusher is compact and stable; and a great use value is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a straw pulverizer with a composite knife roller. Background technique [0002] With the development of agricultural mechanization and the improvement of environmental protection demands, the straw produced in the agricultural production process is now advocated to return the straw to the field, but because incineration usually produces a lot of smoke and dust, it will also seriously affect the air quality, so It is not advisable to return the field by burning. More and more places adopt the mechanical crushing method, and the straw can be crushed directly at the same time as harvesting. The crushed straw is kept in the original cultivated land, which is fast and convenient. Due to terrain constraints, it is difficult for small machinery to operate, let alone large machinery. This has led to the fact that in many mountainous areas, straw i...

[0002] With the development of agricultural mechanization and the improvement of environmental protection demands, the straw produced in the agricultural production process is now advocated to return the straw to the field, but because incineration usually produces a lot of smoke and dust, it will also seriously affect the air quality, so It is not advisable to return the field by burning. More and more places adopt the mechanical crushing method, and the straw can be crushed directly at the same time as harvesting. The crushed straw is kept in the original cultivated land, which is fast and convenient. Due to terrain constraints, it is difficult for small machinery to operate, let alone large machinery. This has led to the fact that in many mountainous areas, straw is basically disposed of by burning, which seriously affects air quality and is also prone to forest fires. Therefore, there is an urgent need for a straw crushing machine suitable for mountainous areas.
