Standing corn stalk front-mounted crushing return-to-field machine

Abstract

The invention discloses a standing corn stalk front-mounted crushing return-to-field machine, and belongs to the agricultural machinery. The machine mainly comprises a right spiral clamping roller anda left spiral clamping roller which are vertically arranged and opposite in rotation direction, during the process of the right and left spiral clamping rollers holding standing corn stalks to a crushing knife roll assembly on the rear side, while the upper sides of the right and left spiral clamping rolls continuously conduct inclining actions to the rear side, and the left spiral clamping roller also performs lateral reciprocating motion to increase the distance between the left spiral clamping roller and the right spiral clamping roller, which not only improves the clamping and conveying effect on the standing corn stalks, but also avoids the winding and blocking of the clamping rollers caused by the corn stalks. The machine has the advantages of novel structure, reasonable structure,high work efficiency, good work quality, reliable use and strong adaptability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a crushing and returning machine tool suitable for standing corn stalks in the field. Background technique [0002] In recent years, with the strong implementation of laws and regulations prohibiting field burning of crop straws, the harmless comprehensive utilization of crop straws has become a problem that must be solved in current scientific and technological work, including methods of crushing corn straws and returning them to the field, improving soil structure, and fertilizing soil fertility. It is one of the ways of comprehensive utilization of straw. However, when the corn stalks standing in the field are crushed and returned to the field using the existing crushing and returning machine after the corn ears are harvested, the standing corn stalks are easily entangled in the straw clips due to the insufficiency and defects in the structural design of the machine tool. On the...

Problems solved by technology

However, when the corn stalks standing in the field are crushed and returned to the field with the existing crushing and returning machine after the corn ears are harvested, the standing corn stalks are easily entangled in the straw clips due to the lack and defects of the machine structure design. On the holding roller, even blockage occurs, and the failure rate is high. At the same time, the transportation of straw from the straw holding roller to the crushing knife roller assembly on the rear side is not smooth, which reduces the operating efficiency of the machine tool and the crushing quality of corn stalks.
