Method and device for killing weeds by using heat energy high-temperature effect

Abstract

The embodiment of the invention discloses a method and a device for killing weeds by using a heat energy high-temperature effect. The device comprises a shell, a Fresnel lens body, a camera used for recognizing weeds and crops, a propeller assembly, a controller and a support, and the controller is used for enabling a condensation point to move to the weeds to conduct high-temperature killing after the weeds are recognized, or scanning the weeds and ground weed seeds one by one to kill the weeds and ground weed seeds. The lower part of the shell is provided with a bracket for supporting the device for killing weeds by utilizing the heat energy high-temperature effect; the camera is arranged at the lower part of the shell; propeller assemblies are mounted on the two sides of the shell; the upper part of the shell is provided with a Fresnel lens body which is used for converging irradiated light rays to form high-temperature condensed light spots; the controller is arranged in the shell and connected with the Fresnel lens body, the camera and the propeller assembly through cables. By applying the weed killer, sunlight can be gathered to form high-temperature spots to kill weeds, the weeds and seeds thereof are killed in a high-energy laser beam scanning mode, and pollution of herbicides to the agricultural ecological environment is avoided.

Description

technical field [0001] The invention relates to agricultural and forestry plant protection technology, in particular to a method and device for killing weeds by utilizing the high temperature effect of thermal energy. Background technique [0002] Farmland and forest fruit land are artificial ecosystems established by people for a certain purpose. This artificial ecosystem has advantages that natural ecosystems do not have, so that the target plants in the farmland or forest fruit land grow vigorously, including non-planting targets. Plants, measures to create favorable growth conditions include regularly turning the ground, loosening the soil, fertilizing, watering, etc., so that the target plants in the agro-ecosystem can grow according to people's wishes, in order to meet people's planting and harvesting goals. However, weeds grow along with crops. Due to people's long-term weeding operations in farmland and forest and fruit fields, the viability and adaptability of weeds...

AI Technical Summary

Problems solved by technology

With the extensive use of chemical herbicides, weed damage has been controlled, but the problem of environmental pollution has come. Residual pesticides are transmitted to grain, fruits, and meat through the food chain, and there are bioaccumulation and amplification effects, which seriously threaten human health.
