Facility cam driving type liquid fertilizer precise positioning and quantitative applying machine and fertilizer applying method

Abstract

The invention discloses a facility cam driving type liquid fertilizer precise positioning and quantitative applying machine and a fertilizer applying method. The specific implementation method comprises the steps that spacing positioning is achieved by using a guide rail and a slider, the machine moves in the guide rail, a fertilization needle is pushed by a came movement fertilization device to be inserted into soil, when the fertilization needle is located at the far angle of repose of a cam, a torsional spring switch is turned on, a Venturi tube accelerates a liquid fertilizer, the liquid fertilizer is quickly jetted, when the fertilization needle returns back, the torsional spring switch is turned off, the liquid fertilizer flows back to a fertilization barrel through an overflow valve, and the processes are repeated to conduct fertilization. The plant spacing of to-be-fertilized plants is input by using a control system, the rotation speed of a fertilization motor can be adjustedaccording to the rotation speed of a driving motor, the fertilization needle is accurately positioned at the root position of a crop to conduct fertilization, and the control system monitors the speed, the pressure, the liquid level and other information in real time. By means of the facility cam driving type liquid fertilizer precise positioning and quantitative applying machine and the fertilization method, automatic precise positioning and quantitative fertilization of the crop in a greenhouse can be achieved, and fertilization can be conducted at the depth required by the crop.

Description

technical field [0001] The invention relates to the field of facility agricultural machinery, in particular to a facility cam-driven liquid fertilizer fertilizer applicator with precise positioning and quantification and a fertilization method. Background technique [0002] The amount of chemical fertilizers used in our country is very large. At present, solid granular fertilizer is the most widely used in agricultural production, but the utilization rate of solid granular fertilizer is not high, the waste is serious, it causes huge pollution to the environment, and excessive application will seriously affect the quality of the soil, and the yield and quality of crops will be affected. Less than a huge boost. Compared with solid fertilizers, liquid fertilizers have great advantages, such as being easily soluble in water, uniform in quality, easy to adjust formula, easy to absorb, lower costs, and environmentally friendly. Liquid fertilizers have broad application prospects....

Problems solved by technology

[0003] Among the existing liquid fertilization machines, the relatively mature ones are mainly large-scale foliar spraying liquid fertilizer fertilization machines. For this type of fertilization machine, my country mainly relies on imports. This type of machine is mainly to spray liquid fertilizer on the surface of crop leaves. The speed is fast, but the price is expensive, the utilization rate is slightly low, and it will cause certain pollution to the environment

The above-mentioned technology is for the large-scale fertilization of the whole crop, and absorbs the liquid fertilizer through the leaves of the crops. It is more suitable for the fertilization of crops with a large outdoor area and strong leaves to absorb liquid fertilizer. For weak crops, root spraying and fertilization is more beneficial for crops to absorb liquid fertilizer, and large-scale foliar spraying type fertilization machines cannot be operated in greenhouses, the operation is complicated, expensive, and cannot be automated.
