Hydraulic fertilizer device

Abstract

The invention discloses a hydraulic fertilizer device, consisting of a pulse generator, a hydraulic fertilizer tank and a pressure transmission assembly. The hydraulic fertilizer device utilizes water hammer principle to generate pressure which drives a hydraulic piston to move in the hydraulic fertilizer tank, the hydraulic piston compresses fertilizer liquid to enter an irritation pipeline, thus realizing the injection of the fertilizer liquid. In the invention, due to the application of the water hammer principle, hydraulic pressure is generated to inject fertilizer, pressure for injecting fertilizer which is higher than the water pressure of the irritation pipeline is generated under the condition that no outside power is added, thus the reliability of fertilizer liquid injection is improved, and water head loss of the irritation pipeline does not occur due to the fertilizer application. The hydraulic fertilizer utilizes hydraulic principle to directly drive the fertilizer liquid in the fertilizer tank for fertilizing, is in parallel usage on the irritation pipeline, has the characteristics of simple structure, easy processing and manufacturing, low cost, uniform fertilizer application, uneasy leakage, controllable fertilizing concentration, convenient installation and usage and the like, and is suitable for the irritation fertilizing requirements of micro-irrigation, sprinkler irrigation, low pressure pipelines and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation and relates to farmland irrigation equipment, in particular to a water-driven hydraulic fertilization device matched with pipelined irrigation. Background technique [0002] Fertigation equipment can inject fertilizer or pesticide solution into the pressure pipe of the irrigation system to achieve the purpose of precise fertilization. Because of its advantages of water saving, fertilizer saving, labor saving, drug saving, high quality, high yield, high efficiency and environmental protection, it can be quickly development and application. At present, the differential pressure fertilization tank that uses irrigation water to directly drive the fertilizer solution in the fertilization tank for fertilization is widely used because of its simple processing and manufacturing, low cost, and no need for external power equipment. However, since the water pressure in the irrigation pipelin...

AI Technical Summary

Problems solved by technology

However, since the water pressure in the irrigation pipeline is directly used for fertilizer injection, the fertilizer injection pressure does not exceed the water pressure in the irrigation pipeline, and a valve is required to adjust the pressure in the irrigation pipeline to generate a certain pressure difference in the irrigation pipeline upstream and downstream of the fertilization tank. In order to inject the fertilizer solution into the irrigation pipeline, the water head loss will be generated in the irrigation pipeline, and the energy consumption of the irrigation system will be increased.

Moreover, the concentration of the fertilizer solution in the differential pressure fertilization tank varies greatly, and the uniformity of fertilization is difficult to be guaranteed.
