A high-pressure gas desorption and viscosity-reducing rotary tillage cutter head, a rotary tiller and a rotary tillage method thereof

Abstract

The invention relates to a high-pressure gas desorption visbreaking rotary tillage cutter which comprises a pneumatic sliding ring, a hollow tool shaft, a cavity tool rest and a hollow tool. The hollow tool shaft is rotatably connected with a machine frame, the pneumatic sliding ring is mounted between the hollow tool shaft and the machine frame, the cavity tool rest is mounted on the hollow toolshaft, the hollow tool is mounted on the cavity tool rest, cavities are formed in the pneumatic sliding ring, the hollow tool shaft, the cavity tool rest and the hollow tool, the cavities of the pneumatic sliding ring, the hollow tool shaft, the cavity tool rest and the hollow tool are sequentially communicated, a gas pipe joint is arranged on the pneumatic sliding ring, and a plurality of uniformly distributed gas outlet holes are formed in a soil-engaging component of the hollow tool. The invention further relates to a rotary tiller and a rotary tillage method thereof, and belongs to the technical field of agricultural equipment. High-pressure gas is blown out from the gas outlet holes of the hollow tool, soil is directly blown away, and adhesion is decreased. Along with high-speed rotation of the rotary tillage cutter, the high-pressure gas forms an air isolation film between the rotary tillage cutter and the soil, and soil adhesion is decreased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and tools, in particular to a high-pressure gas desorption and viscosity-reducing rotary tillage cutter head, and also relates to a rotary tiller using the rotary tiller cutter head and a rotary tillage method thereof. Background technique [0002] At present, the commonly used rotary tillage cutter directly contacts the soil, relying on the high-speed rotating centrifugal force of the cutter to throw the soil away from the cutter. However, the soil is highly viscous and adheres to the surface of the tillage cutter, which increases the resistance of the cutter during tillage and reduces the life of the cutter. [0003] The applicant found that if the third factor—high-pressure gas is introduced between the cutter and the soil, an air film is formed between the cutter and the soil, which will greatly reduce the adhesion of the soil to the cutter, reduce the tillage resistance, and imp...

Problems solved by technology

[0002] At present, the commonly used rotary tillage cutter is in direct contact with the soil, relying on the high-speed rotating centrifugal force of the cutter to throw the soil away from the cutter, but the soil is relatively viscous and adheres to the surface of the tillage cutter, which increases the resistance of the cutter during tillage and reduces the life of the cutter.
