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.

Example Embodiment

[0014] Example 1:

[0015] Refer to figure 1 . The pulse generator is composed of the water inlet pipe 1, the pressure chamber 2, the hammer valve 3, the drain pipe 4 and the water hammer pressure energy release pipe 5; it is composed of the pressure fertilizer tank 11, the hydraulic thin plunger 10, the hydraulic inlet 8, and the fertilizer injection port 13. The one-way valve B14 constitutes a hydraulic fertilizer tank. The hydraulic thin plunger 10 divides the pressure fertilizer tank 11 into a hydraulic tank 9 and a fertilizer tank 12. With the implementation of the fertilization process, the hydraulic tank 9 and the fertilizer tank 12 dynamically change , The hydraulic silo 9 gradually expands, and the fertilizer silo 12 gradually shrinks; the pressure transmission component is composed of the one-way valve A6 and the hydraulic transmission pipeline 7; one end of the pressure transmission component is connected with the water hammer pressure energy release pipe 5 of the puls...

Example Embodiment

[0017] Example 2:

[0018] Refer to figure 2 . The basic structural features of the hydraulic fertilizing device shown in Example 2 are similar to those in Example 1, except that the hydraulic fertilizing tank is inverted. The parts with the same structure in Example 2 and Example 1 are denoted by the same reference numerals, and will not be described again. Be explained. The principle and implementation process of this embodiment are also the same as those of the first embodiment, so the description thereof will be omitted.

[0019] The hydraulic fertilization device constructed by the invention is used in parallel on the irrigation pipeline. When in use, the water inlet pipe 1 of the pulse generator is connected to the upstream end of the irrigation pipe, and the fertilizer injection port 13 of the hydraulic fertilization tank is connected to the downstream end of the irrigation pipe.

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...
