Electromagnetic Control Pneumatic Drive Liquid Fertilizer Double Fertilizer Distributor

Abstract

The invention provides an electromagnetic control and pneumatic driving double-fertilizer-channel discharging and application distributor of liquid fertilizer and belongs to agricultural machinery. The distributor is composed of a barrel type main shell body, a front shell body, a rear shell body, a supporting frame and two elastic membranes, two liquid fertilizer input check valves, two liquid fertilizer output check valves, an air inlet electromagnetic control valve, a front air distribution valve body, an air exhausting electromagnetic control switch, a rear air distribution valve body, a synchronous driving connecting shaft and two pressure springs in an assembling manner; a first fertilizer conveying channel and a second fertilizer conveying channel are formed in the front shell body, the rear shell body and the barrel type main shell body; an air feeding chamber and an air exhausting chamber are formed between the front shell body and the supporting frame, and between the rear shell body and the supporting frame respectively; a first pneumatic driving chamber and a second pneumatic driving chamber are formed among the two elastic membranes and the supporting frame respectively; a first liquid fertilizer chamber and a second liquid fertilizer chamber are formed among the two elastic membranes and the barrel type main shell body respectively. The electromagnetic control and pneumatic driving double-fertilizer-channel discharging and application distributor of the liquid fertilizer is novel and reasonable in structure, stable in operation, high in automation degree, reliable in working, good in working effect and long in service life.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a control component for conveying, discharging, distributing and distributing liquid fertilizer. Background technique [0002] At present, liquid fertilizers are widely used in agricultural production due to their low production costs, convenient fertilization, fast absorption, low fertilizer consumption, and improvement of the quality of agricultural products. Scientifically and rationally applying liquid fertilizers and improving fertilizer utilization rates are of great significance to increasing crop yields, reducing farmers' input costs, and preventing environmental pollution. Although there are many enterprises producing liquid fertilizer in my country at this stage, there are very few enterprises producing liquid fertilizer application equipment. Due to defects in structural design and processing technology, various liquid fertilization machines and tools used in actual prod...

Problems solved by technology

Due to defects in structural design and processing technology, various liquid fertilization machines used in actual production have shortcomings such as large energy loss in fertilizer transportation and insufficient spraying pressure.

At the same time, its fertilizer road control system mainly uses cam ejector rods to control the spraying operation. Such components have complex structures and require high processing accuracy and sealing performance. During long-term fertilization operations, the control system is severely corroded and worn, which greatly shortens the service life of the machine tools. , affecting the use effect and causing fertilizer loss and waste
