Pneumatic zero-speed hole-pricking liquid fertilizer deep application mechanism

Abstract

The invention relates to a pneumatic zero-speed hole-pricking liquid fertilizer deep application mechanism and belongs to agricultural machinery. N liquid fertilizer application needle assemblies are inserted in a moving flat plate in a telescopic movable mode; a pressing plate is assembled on the upper parts of the liquid fertilizer application needle assemblies; a steel pipe and a support are fixedly arranged on the moving flat plate; the steel pipe is communicated with the liquid fertilizer application needle assemblies; an air cylinder rod arranged on a vertical air cylinder on the support is connected with the pressing plate; the moving flat plate is arranged on the back side part of a fixedly arranged horizontal air cylinder; a main gas pipe is used for communicating a gas pump with an air cylinder motion controller; a lead is used for communicating a speed measuring sensor with the air cylinder motion controller; the horizontal air cylinder is used for communicating the air cylinder motion controller with the horizontal air cylinder; a gas pipe of the vertical air cylinder is used for communicating the air cylinder motion controller with the vertical air cylinder; and a hose is used for communicating a liquid pump with the steel pipe. The pneumatic zero-speed hole-pricking liquid fertilizer deep application mechanism is reasonable in structure, high in automation degree, high in hole-pricking operation and fertilizer application operation quality, high in fertilizer efficiency utilization rate and low in environmental pollution, and is favorable for growth and absorption of crops.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a pneumatic zero-speed hole piercing liquid fertilizer fertilization operating mechanism that can be assembled on a liquid fertilizer fertilization machine tool. Background technique [0002] The deep application type liquid fertilizer machine is a working tool that applies liquid fertilizer deep into the soil and acts on the roots of crops. It has the characteristics of obvious fertilizer saving effect, increased production, increased income, and significant economic and social benefits. However, because the existing deep-spraying liquid fertilizer applicator is driven by the rear wheel of the tractor, the machine tool penetrates the fertilizer spray needle into the soil to a certain depth through mechanical transmission, and completes the deep fertilization operation. Reduced, it is difficult for the machine tool to achieve zero-speed piercing, and the whole machine is mechanicall...

Problems solved by technology

However, because the existing deep-spraying liquid fertilizer applicator is driven by the rear wheel of the tractor, the machine tool penetrates the fertilizer spray needle into the soil to a certain depth through mechanical transmission, and completes the deep fertilization operation. Reduced, it is difficult for the machine tool to achieve zero-speed pricking, and the whole machine is mechanically driven, so the machine tool is complicated

Existing deep-applying liquid fertilizer applicators are difficult to achieve zero-speed piercing, long strips of notches appear on the ridge surface, the quality of piercing and fertilization is poor, and the liquid fertilizer volatilizes seriously, which affects the absorption and growth of liquid fertilizer by crops and pollutes the environment
