Standing corn stalk crushing, kneading and returning machine

Abstract

The standing corn stalk crushing, kneading and returning machine belongs to agricultural machinery; the machine includes a corn stalk introduction mechanism composed of a reel chain group and a stalk roller, a corn stalk composed of a moving knife, a fixed knife, a material conveying side plate, and a knife hub. Straw cutting and crushing mechanism, rubbing and crushing mechanism composed of toothed rubbing roller, toothed rubbing block, roller cover plate, rubbing gap adjustment bolt group, pressure spring, external power input shaft, driving pulley, driven The power transmission system composed of pulley, transmission belt, transfer shaft, gearbox, reversing transmission gearbox, cutter hub drive shaft, and cutter hub; through the combination of cutting and crushing of corn stalks and extrusion, cutting, tearing, kneading and crushing combined operations, the Improve the quality of corn stalk crushing and returning to the field, which is beneficial to the rot and degradation of corn stalks, and give full play to the advantages of corn stalk returning to the field. The structure of the machine is novel and reasonable, the operation quality is good, the efficiency is high, and the use is reliable.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a machine tool for returning corn stalks to the field. Background technique [0002] Since corn stalks are directly crushed and returned to the field, which has the advantages of low operating costs and high comprehensive benefits, it has become one of the main utilization methods for turning waste into treasure. However, due to the deficiencies and defects in the structural design of the currently used corn stalk crushing and returning machines, the crushing effect on the corn stalks is poor, resulting in slow decomposition and long time after the corn stalks are returned to the field, and the effective nutrients in the corn stalks are difficult to obtain. It can be reliably absorbed and utilized by the soil, and it is difficult to exert the advantages of fertilizing the soil and improving the soil structure. At the same time, during the sowing operation, the seed grains are easily...

Problems solved by technology

However, due to the deficiencies and defects in the structural design of the currently used corn stalk crushing and returning machines, the crushing effect on the corn stalks is poor, resulting in slow decomposition and long time after the corn stalks are returned to the field, and the effective nutrients in the corn stalks are difficult to obtain. It can be reliably absorbed and utilized by the soil, and it is difficult to exert the advantages of fertilizing the soil and improving the soil structure. At the same time, during the sowing operation, the seed grains are easily sown on the unrotted corn stalks, and the seeds cannot fully contact with the seedbed soil, causing the seeds to rot. The germination rate is reduced, which affects the quality of sowing operations
