Problems solved by technology

[0005] At present, most of the injection devices do not use the anti-backflow structure, and the mixing time of the fertilizer liquid and irrigation water is short, making it very uneven; at the same time, the fertilizer sprayed by the nozzle The liquid volume and liquid water pressure are not easy to adjust and control. It is often necessary to install various electromagnetic valves to control the flow and pressure, which increases the overall cost. Generally speaking, most injection nozzles are not designed for water and fertilizer integration facilities.

Embodiment 1

[0035] Such as figure 1 As shown, a spraying device for water and fertilizer integrated equipment, the spraying device includes a mixing chamber 1 and a spraying chamber 2 that communicate with each other, the connection between the mixing chamber 1 and the spraying chamber 2 is sealed, and the mixing chamber 1 is in the form of Cylindrical, the injection chamber 2 is conical, the left end is small and the right end is large, the side wall of the mixing chamber 1 is provided with a feed port 3, which is used for irrigation water and liquid fertilizer to enter the mixing chamber 1 for mixing, and the right side of the injection chamber 2 The wall is provided with a plurality of first injection holes 4 to make the injection more uniform. A stirring device located below the feed port 3 is provided between the two inner walls of the mixing chamber 1. Between the stirring device and the mixing chamber 1 is a rotating The first sleeve 14 connecting the two cavities is arranged betwe...

Embodiment 2

[0038] Such as figure 1 with 3 As shown, in this embodiment, the flow control assembly includes a piston rod 13, a control rod 7, and a return spring 11. The piston rod 13 is slidably sleeved in the first sleeve 14, and the piston rod 13 and the first sleeve The inner diameter of 14 is matched, and the two ports of the first sleeve 14 are provided with retaining rings 15, which can prevent the piston rod 13 from slipping out of the first sleeve 14, and the side wall of the left end of the piston rod 13 is provided with the second injection nozzle. A plurality of flow-limiting grooves 21 corresponding to the hole 5, the plurality of flow-limiting grooves 21 are evenly distributed on the side wall of the piston rod 13 in an annular shape, the length of the flow-limiting groove 21 is half of the length of the piston rod 13, and the side wall of the piston rod 13 is provided with There is a circle of grooves, and a sealing ring 12 is arranged in the groove, and the sealing ring 1...

Embodiment 3

[0040] Such as figure 1 with 4 As shown, in this embodiment, a second sleeve 9 is provided through the side wall of the injection chamber 2, and the second sleeve 9 and the side wall of the injection chamber 2 can slide relatively. Internal thread, the side wall of the control rod 7 is provided with an external thread matching the internal thread, the control rod 7 is threadedly connected with the second sleeve 9, and the end of the second sleeve control located in the spray chamber 2 is in contact with the return spring 11, and the control rod 7 Both the second sleeve 9 and the second sleeve 9 are made of rubber material, which can enhance the sealing performance between the control rod 7 and the second sleeve 9, the second sleeve 9 and the injection chamber 2, and avoid waste caused by excessive leakage of fertilizer liquid . During use, by manually rotating the second sleeve 9 clockwise, relative displacement occurs between the second sleeve 9 and the control rod 7, and t...

Abstract

The invention discloses a spraying device for water and fertilizer integrated equipment. The spraying device comprises a mixing cavity and a spraying cavity which communicate with each other, a feed inlet is formed in the side wall of the mixing cavity, a first spraying hole is formed in the side wall of the spraying cavity, a stirring device located below the feed inlet is arranged between two inner walls in the mixing cavity, a first sleeve communicating with the mixing cavity and the spraying cavity is arranged between the mixing cavity and the spraying cavity, a second spraying hole is formed in the side wall of the sleeve in the circumferential direction, and a flow control assembly located in the spraying cavity is arranged on the path where the mixing cavity communicates with the second spraying hole. The spraying device is used for controlling the mixing time of irrigation water and liquid fertilizer, so that the irrigation water and the liquid fertilizer are mixed more uniformly, meanwhile, the water outlet amount and the water outlet pressure of the fertilizer water can be adjusted, and better spraying on crops is facilitated.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer irrigation, in particular to a spraying device used for water and fertilizer integrated equipment. Background technique [0002] Water and fertilizer integration technology has achieved a revolutionary transformation of water and fertilizer management through the transformation of channel water delivery to pipeline water delivery, land irrigation to farmer irrigation, soil fertilization to crop fertilization, and separation of water and fertilizer to integration of water and fertilizer. The integration of water and fertilizer is to use the pressure system (or the natural drop of the terrain) to mix the liquid fertilizer according to the soil nutrient content and the law and characteristics of the fertilizer demand of the crop species, together with the irrigation water, through the controllable pipeline system for water supply, Fertilizer supply, after the water and fertilizer are mix...
