One-time straw chopping and stubble returning machine

Abstract

The invention discloses a one-time-chopping stubble-cleaning returning machine for straws. The machine comprises a rack, wherein the rack comprises a front cross beam and a rear cross beam; a frame is arranged in the middle of the rack and connected with a farm machine; a bearing seat is arranged on each of the two sides of the upper side surface of the front cross beam and the rear cross beam of the rack; a transmission shaft seat is arranged in the middle position between the bearing seats on the two sides of the upper side surface of the rack; a fixing cross beam is arranged on the rear side surfaces of the bearing seats and the transmission shaft seat; a connecting seat is arranged at each of the two ends of the front cross beam of the rack; a vertically adjustable compression roller is fixedly arranged on the corresponding connecting seat through a connecting plate; two connecting keys are arranged on each of the two sides of the front side surface of the front cross beam of the rack; the frame and the connecting keys are connected with the farm machine; a bearing box is arranged on the bearing seat on the left side; a transmission shaft gear is arranged on the front side in the bearing box, a transmission gear is arranged in the middle in the bearing box, and a transmission bar gear is arranged on the rear side in the bearing box. In general, the one-time-chopping stubble-cleaning returning machine for straws, provided by the invention, has the advantages of being simple in structure, low in manufacturing cost, convenient to operate, good in chopping effect, beneficial for cost reduction and long in service life and the like.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a straw returning machine, and specifically designs a straw one-time shredding and stubble returning machine. Background technique [0002] At present, after the crops are harvested, especially the corn stalks are very necessary to return to the field, which can not only reuse energy but also ensure the fertility of the soil, and at the same time avoid environmental pollution caused by burning straws. Therefore, people have invented many kinds of straw returning machines, most of which use straw crushing devices. This kind of device is complicated to manufacture, and the power requirements for matching with it are high, the power consumption is large, and the work efficiency is not ideal. It needs to be crushed more than twice to achieve crushing. In addition, the return machine wears quickly, the straw has high toughness, and the crushed straw on the surface is mostly broken and connected...

Problems solved by technology

Therefore, people have invented many kinds of straw returning machines, most of which use straw crushing devices. This kind of device is complicated to manufacture, and the power requirements for matching with it are high, the power consumption is large, and the work efficiency is not ideal. It needs to be crushed more than twice to achieve crushing. In addition, the return machine wears quickly, the straw has high toughness, and the crushed straw on the surface is mostly broken and connected, and the crushing quality is poor. The ground is like a layer of carpet, which is not conducive to the soil to absorb sunlight. When the soil is wet, the crushed Afterwards, it is very easy to cause land compaction, land plowing and sowing operations are difficult, and its crushing nature makes the straw dry faster, loses nutrients, and greatly reduces the utilization rate of nutrients
