A fixed root water spray system and its realization method

Abstract

The invention discloses a root water spraying system. The root water spraying system is characterized by comprising a transplanter, a water tank, a fixing frame, a water supply mechanism, a water storage tank and a spraying mechanism, wherein the water tank is arranged on the transplanter, the water storage tank is mounted on the transplanter through the fixing frame, the spraying mechanism is connected with the water storage tank, and the water supply mechanism is connected with the water storage tank. The water storage tank simultaneously stores water and pressure, the water discharge time is shortened and the water spraying pressure is increased by means of high pressure in the water storage tank; meanwhile, the water spraying amount can be controlled by regulating the pressure in the water storage tank. A water control switch is mounted, a submerged pump is automatically controlled by use of water flow, and energy conservation and environmental protection are realized. The working efficiency is improved, the labor intensity is reduced, and water resources are saved. The system is simple in structure, can realize automation to a certain extent and has high popularization applicability.

Description

technical field [0001] The invention relates to the field of crop transplanting in agricultural production, in particular to a fixed-root water spray system and a realization method thereof. Background technique [0002] After transplanting vegetables and other crops, in order to ensure the survival rate, a certain amount of fixed root water needs to be sprayed, so that the seedlings can adapt to the transplanting environment, accelerate the development of the root system, and quickly turn green and grow healthily. An appropriate amount of sprayed fixed root water can ensure the transplanting of tobacco seedlings Survival rate, improve crop yield and quality, maximize economic benefits and water resource utilization. When transplanting in a large area, due to small seedling pits, short pit spacing, cumbersome manual watering, high field labor intensity, low efficiency, and difficulty in accurately controlling the amount of water, it is easy to cause waste of water resources....

AI Technical Summary

Problems solved by technology

The advantages of the mechanical trigger device are simple structure, convenient installation and good economy. The disadvantage is that it requires high assembly accuracy, and relative movement will cause wear. Corrosion-resistant and wear-resistant materials must be used in key parts.

The electronic trigger fixed-root water spray device generally adopts the method of intelligent control, and the signal is detected by the camera or sensor (light sensor, metal probe, infrared sensor, etc.), and then the signal is transmitted to the control system, and then controlled by the control system. The system issues an instruction to let the solenoid valve open the watering switch. This electronic control fixed root water spray device makes up for the shortcomings of the mechanical linkage type. The structure is relatively simple, but the detection device is easily disturbed. At the same time, the control system and electronic components must be Ensure the stability of the working state, otherwise it is prone to leakage, too much or too little pouring

[0003] In the prior art, Liu Shuangxi, Wang Jinxing and others designed the "Smart Tobacco Quantitative Watering Machine" (Patent No.: CN201310532942.X), the water storage tank of the intelligent Tobacco Quantitative Watering Machine designed by them is installed in the watering machine At the end, the submersible pump is placed in the water tank. There are two cylindrical holes above the water storage tank. One cylindrical hole is connected to the water outlet of the submersible pump through a water delivery pipe, and the other cylindrical hole of the water storage tank is connected to the water tank through a water delivery pipe. Continuously supply water to the water storage tank to ensure that the water storage tank is always full of water. This technology has the following disadvantages: (1) the water storage tank of this technology is only used for water storage; (2) the submersible pump of this technology is always in working condition, Unable to control the automatic pumping and stopping of the submersible pump, which consumes a lot of power and wastes resources
