Floating type multilayer cut straw smashing and returning machine

Abstract

The invention relates to a floating type multilayer cut straw smashing and returning machine, and belongs to the technical field of agricultural machinery. The floating type multilayer cut straw smashing and returning machine comprises a suspension mechanism and a main transmission gear box. A left fixed side plate and a right fixed side plate on two sides of the suspension mechanism are provided with front shafts in a supporting manner and are hinged to a left floating side plate and a right floating side plate, a floating framework is fixed to a position between the left floating side plate and the right floating side plate, a rear shaft is supported between the left floating side plate and the right floating side plate, the rear end of the suspension mechanism is hinged to a front extension end of a floating control frame by a hinge hydraulic oil cylinder, and the rear end of the floating control frame is hinged to the floating framework by connecting rods; a hinged output end of the main transmission gear box is in transmission connection with an input end of a side gear box by a transmission shaft which is coaxial with a hinged shaft, the side gear box is mounted on one of the floating side plates, and an output end of the side gear box is in transmission connection with the rear shaft. The floating type multilayer cut straw smashing and returning machine has the advantages that the tilling depths can be conveniently regulated and controlled as needed, and the difficult problems of aerial soil due to straw after the straw returns to fields and high straw ratios can be solved; the floating type multilayer cut straw smashing and returning machine is excellent in operating performance and adaptability, cutter shafts can be prevented from being damaged due to bumping and impact, and accordingly machines and tools are reliable and durable.

Description

technical field [0001] The invention relates to a straw crushing and returning machine, in particular to a floating multi-layer cutting straw crushing and returning machine, which belongs to the field of agricultural technology. Background technique [0002] In agricultural production, after the crops are harvested, the stalks in the farmland need to be removed to prepare for the planting of later crops. The traditional method of straw removal is manual pulling and burning, which seriously pollutes the environment, so it has been gradually replaced by straw crushing and returning to the field. Although the existing straw crushing and returning to the field can avoid pollution caused by burning straw and achieve the purpose of improving farmland soil, however, due to its single-axis or multi-axis fixed connection structure (for a typical structure, please refer to the Chinese patent document with application number 201310536560.4), it is suitable for Poor performance, deep p...

AI Technical Summary

Problems solved by technology

The traditional method of straw removal is manually pulled out and burned, which seriously pollutes the environment, so it has been gradually replaced by straw crushing and returning to the field.

Although the existing straw crushing and returning to the field can avoid pollution caused by burning straw and achieve the purpose of improving farmland soil, however, due to its single-axis or multi-axis fixed connection structure (for a typical structure, please refer to the Chinese patent document with application number 201310536560.4), it is suitable for Poor performance, deep plowing is difficult, after the rotary tillage straw is returned to the field, the ratio of straw to soil and straw is high, the operation effect is not ideal, and there is a problem that it is easy to overload and cause the tillage cutter or drive shaft to break

In addition, since the knife axis of the crushing device is parallel to the ground, the smashing knife is perpendicular to the ground (for a typical structure, please refer to the Chinese patent document with application number 201310223104.4), it is impossible to crush and return the upright straw to the field
