Standing type machine for smashing and rubbing corn stalks and returning corn stalks to field

Abstract

The invention relates to a standing type machine for smashing and rubbing corn stalks and returning the corn stalks to field and belongs to agricultural machinery. The machine comprises a corn stalk guiding mechanism composed of poking chain groups and stem pulling rolls; a corn stalk cutting and smashing mechanism composed of moving knifes, fixed knifes, material conveying side plates and knife hubs; a rubbing, squeezing and crushing mechanism composed of a tooth-type rubbing roll, tooth-type rubbing blocks, a roll shield plate, a rubbing gap adjusting bolt group and a pressure spring; and apower driving system composed of an external power input shaft, a driving belt pulley, a driven belt pulley, a driving belt, a transfer shaft, a gear box, a reversing driving gear box, knife hub driving shafts and knife hubs. The machine has the beneficial effects that through the combined compound operation mode of cutting, smashing, squeezing, tearing, rubbing and crushing the corn stalks, the quality of smashing the corn stalks and returning the corn stalks to field is increased, the rot and the degradation of the corn stalks are benefitted and the advantages of returning the corn stalks tofield is fully played; and the machine is novel and reasonable in structure, good in operating quality, high in efficiency and reliable in use.

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...

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
