Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, a full-coverage laser lattice structure based on heat injury and weeding is characterized in that the fixed frame 1 is a cylindrical surface, and N holes are arranged in each row on the fixed frame 1, and M rows are arranged in total. The diameter of the hole is D1, the distance between the holes in the same row is d1, and the distance between the holes in the adjacent row is d2, ensuring that d1+D1=M·D2 (this relationship can be satisfied by changing the value of d1). The axial length of the cylindrical surface L=(M-1)·(d1+D1), the arc length S>M·D1+(M-1)·d2, the diameter of the laser used is equal to the diameter of the hole, and the laser emits a spot at a distance R The diameter is D2. The row direction of the fixed frame 1 is set as the x-axis direction, and the laser dot matrix arranged on the...

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...
