Pneumatic soil deep loosening head and working method thereof

Abstract

The invention discloses a pneumatic soil deep loosening head and a working method thereof. A baffle plate is arranged inside a shell, and a spray hole can be opened or closed when the baffle plate ispositioned at different angles. When the spray hole is closed, high gas pressure acts on the surface of a piston at the lower end, and equipment enters soil. When the spray hole is opened, compressedgas is sprayed from the spray hole, and the soil is loosened by gas explosion. The piston and a spring form a soil chiseling mechanism, when pulse gas pressure acts on the piston, the soil chiseling mechanism vertically moves to chisel the soil, the shell is pressed down by the aid of external force, and the deep loosening head can be easily inserted into the soil. The deep loosening head can be used for loosening the soil, can also be used for entering the soil and solves the problems that implements difficultly enter the soil, excessive force is applied to the implements, stress is concentrated and the like in the prior art. Resistance is uniformly distributed, and the implements more easily enter the soil.

Description

technical field [0001] The invention belongs to the field of mechanical soil subsoiling, and in particular relates to a pneumatic subsoiling head and a working method thereof. Background technique [0002] Soil deep loosening refers to a farming technique that uses external force to loosen the soil, break the bottom of the plow, improve the structure of the plow layer, and enhance the ability of soil water storage and moisture conservation and drought resistance and drainage. Carrying out subsoiling soil operations is beneficial to crop growth and is one of the important means to increase crop yield. In agricultural production, soil subsoiling operations mainly use traditional subsoilers, such as shovel subsoilers, vibrating subsoilers, etc. In recent years, a subsoiling method that uses compressed gas to blast the soil has emerged, which is used in conjunction with air gun pressure and high-pressure gas injection. The above two common deep loosening methods have the follo...
