Intelligent fertilizer applicator control system and method and intelligent fertilizer applicator

Abstract

The invention discloses an intelligent fertilizer applicator control system. The front end of the fertilizer applicator is hinged to a work head for fertilization. The fertilizer applicator control system comprises a hydraulic power system for performing the work head lifting and dropping action and the automatic fertilization action, a lifting and dropping control module connected to the hydraulic power system and used for controlling the hydraulic power system to perform work head lifting and dropping action, and a fertilization control module connected to the hydraulic power system and usedfor controlling the hydraulic power system to perform automatic fertilization. The lifting and dropping control module and the fertilization control module are connected in parallel and are connectedto a system power supply. The hydraulic power system is transmission-connected to a diesel engine driving system of the fertilizer applicator. The diesel engine driving system provides a power sourcefor the hydraulic power system. The initial position of the work head is the highest position. The lifting and dropping control module contacts with trees and is started to control the hydraulic power system to perform work head dropping. The work head drops the lowest position and presses to start the fertilization control module so that the fertilization control module controls the hydraulic power system to perform automatic fertilization and thus the intelligent fertilization is realized.

Description

technical field [0001] The invention relates to an intelligent fertilizer spreader control system and method, belonging to the technical field of agricultural machinery control, and also relates to an intelligent fertilizer spreader. Background technique [0002] The management of orchards includes multiple production links such as planting, fertilization, irrigation, pruning, and pest control. [0003] Tree fertilization is a very important and necessary orchard management process. At present, the method of fertilizing fruit trees in my country mainly adopts traditional manual fertilization. Due to the uneven fertilization and the difficulty in controlling the amount of fertilization, this method not only affects the quality of the fruit, but also affects the quality of the fruit. It causes a serious waste of manpower and material resources, and the corrosiveness of chemical fertilizers can cause serious harm to human health and pollute the environment to a certain extent. ...

[0003] Tree fertilization is a very important and necessary orchard management process. At present, the method of fertilizing fruit trees in my country mainly adopts traditional manual fertilization. Due to the uneven fertilization and the difficulty in controlling the amount of fertilization, this method not only affects the quality of the fruit, but also affects the quality of the fruit. It causes a serious waste of manpower and material resources, and the corrosiveness of chemical fertilizers will cause serious harm to human health and pollute the environment to a certain extent.

[0004] In recent years, some working heads can only perform mechanical ditching or digging operations, and need the assistance of fruit growers to complete fertilization operations, which cannot achieve fixed-point and quantitative control of soil covering and fertilization, and have not completely liberated the labor force. Fertilization benefits lower cost

There is also a part of the working head that uses the position information determined by the laser scanner and the sensor to control the fertilization device to perform fixed-point and quantitative fertilization on the fruit trees in the orchard. Although the labor force has been liberated and fixed-point quantitative intelligent fertilization has been realized, the failure rate of the laser scanner and sensors High, and the cost is high, and the reliability and practicability of the use need to be improved
