Complete-coverage laser lattice structure and method based on thermal burn weeding

Abstract

The invention relates to a complete-coverage laser lattice structure and method based on thermal burn weeding. The complete-coverage laser lattice structure comprises a fixing frame and lasers, wherein the fixing frame adopts a cylindrical surface or another cylinder, a plurality of holes are formed in the fixing frame, a laser is fixedly mounted in each hole, the lasers form a lattice on the fixing frame, and lasers emitted by the lasers are converged on the same straight line. The hole pitch of two adjacent lines is constant, and holes of two adjacent rows have certain displacement so as to ensure that a coordinate gap does not exist during radiation of the lasers. The lasers are connected with a controller, positions of weeds are positioned by a monitor, the controller is used for controlling corresponding laser switches on a lattice instrument, and the lasers are emitted to weed through thermal burn. According to the complete-coverage laser lattice structure and method, the structural design is simple and reasonable, and accurate weeding can be performed row by row by controlling the switches of corresponding lasers according to the specific positions of the weeds; and when the structure is placed on an agricultural machine, complete-coverage and timely laser weeding is achieved along with the forwarding of the agricultural machine.

Description

technical field [0001] The invention relates to a full-coverage laser dot matrix structure, which is mainly used for weeding in heat-damaged fields. Background technique [0002] For a long time, the food that people rely on for survival has been provided by methods such as planting plants and raising animals. However, in the process of planting plants, it is inevitable to encounter the problem of preventing and controlling weed damage. Weeds are plants that grow in inappropriate areas. They are often associated with different growth and development stages of crops. They compete fiercely with crops for water and nutrients, seriously interfering with the normal growth of crops, resulting in reduced yield and quality of crops. [0003] Methods of weed control in farmland include mechanical, chemical, human, electrostatic, biological weeding, etc. In recent years, due to the high efficiency of chemical weeding, it has become the main method of weeding. But the widespread use o...
