Problems solved by technology

The main disadvantages of this Venturi fertilizer applicator are: 1. It brings pressure relief to the irrigation system, which is not suitable for irrigation systems with pressure; 2. It solves the problem of pressure relief, but it cannot control the amount of fertilizer applied per unit time. Unable to achieve precise fertilization

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] refer to figure 2 , the water-soluble fertilizer precision fertilization device according to the present invention includes an electric control system 7 , a speed regulation system 6 , a feedback sensor and an actuator 4 .

[0031] The feedback sensor includes a water flow meter 3 installed on the irrigation pipeline 1 and a fertilizer injection flow meter 5 installed on the fertilizer pipeline 2, which are used to dynamically sense the change of fertilizer injection per unit time, and send the sensing results to the electronic control system. System 7, forming the next adjustment cycle. Feedback sensors need to be corrosion-resistant, anti-particle blocking, and suitable for viscous liquids, so as to be suitable for sensing changes in fertilizer flow and harsh operating environments.

[0032] The electronic control system 7 is used t...

Abstract

The invention relates to the field of agricultural fertilization equipment, in particular to a water soluble fertilizer precision fertilization device and fertilization method. The device comprises anelectric control system, a speed regulating system, a feedback sensor and an actuator. Precision fertilization is achieved by a method for regulating the output power of the actuator by real-time feedback and dynamic current regulation. Use of water soluble fertilizers can be precisely controlled, the functions of saving the fertilizers, time and labor are achieved in the water and fertilizer integration process, the system can be rapidly regulated to stably run by constrained parameters including step parameters, differential divisors and integrating factors of the speed regulating system, water soluble fertilizer use precision of the device is improved, and operation is simplified.

Description

technical field [0001] The invention relates to the field of agricultural fertilization equipment, in particular to a water-soluble fertilizer precision fertilization device and a fertilization method. Background technique [0002] The integration of water and fertilizer is an inevitable trend in the development of science and technology and green agriculture. Strictly controlling the amount of water and fertilizer is the core of the integration of water and fertilizer, and the amount and timing of fertilizer use are even more important. [0003] The fertilizer used in the integration of water and fertilizer must be water-soluble, and combined with the irrigation system, water and fertilizer can be applied at the same time. At the present stage, the method of applying water and fertilizer at the same time is mainly carried out by using a Venturi fertilizer applicator (or a Venturi variant fertilizer applicator) in the irrigation pipeline. The device structure is as follows:...
