Description

Liquid spraying equipment for rice planting Technical Field The invention relates to the technical field of rice planting, in particular to a liquid spraying device for rice planting. Background In order to maximize the utilization of land area, the cultivation mode of interplanting fruit trees and rice is adopted, rice is planted in a neutral gear with a width of several meters between two adjacent rows of fruit trees, and the rice is planted in a large range by adopting a rice transplanter, so that a rice planting layout with straight line direction and regular line spacing is formed. However, the large plant protection mechanical equipment cannot enter the interplanted plots to carry out the liquid medicine spraying operation due to the limitations of the shielding of fruit tree plants and the narrow field space, and the technical difficulty of preventing and controlling the diseases and insect pests of rice is caused. When unmanned aerial vehicle sprays because of the simple operation, efficient by wide application down, unmanned aerial vehicle sprays the fly height that needs to keep more than three meters from the rice however, in the interplanting scene, the pesticide can spill on a large amount of peripheral fruit trees, causes fruit tree phytotoxicity, seriously influences fruit output and quality, can't adapt to the rice plant protection demand of mating planting plot. At present, in the region where fruit trees and paddy rice are interplanted, farmers adopt manual pesticide carrying barrels to spray or set up a pesticide pump on the ground, and spray through long water pipes connected with spray heads, the farmers are required to walk in the paddy field in two modes, so that the labor intensity is high, the operation efficiency is low, the long water pipes are sprayed in a mode limited by the length of the paddy field, and the practical operation requirements of interplanted paddy rice disease and pest control are difficult to meet. Therefore, there is a need for a miniaturized and portable rice liquid spraying device that adapts to the planting mode of interplanting the fruit tree with rice.
