Farmland weed killer

Abstract

The invention discloses a farmland weed killer. The farmland weed killer comprises a vehicle body with a crawler walking mechanism, a driving operation position is arranged at the upper portion of thevehicle body, and a stem and leaf processing device, a grass root collecting device and a killing device are sequentially arranged at the vehicle body horizontal position between a crawler and the driving operation position in the advancing direction of the vehicle body towards the rear portion of the vehicle body. According to the characteristics of grass plants and grass roots, the farmland weed killer collects the grass plants and the grass roots in a targeted manner and then kill the grass plants and the grass roots, and the problems that large harm is caused to soil when herbicide is sprayed at present, secondary growth occurs due to the fact that the grass roots and grass seeds cannot be completely killed through mechanical weeding, and the cost is high after multiple times of weeding are solved. According to the weed killer, the grass seeds, grass stems and the grass roots can be effectively and completely killed at a time, the problem that the grass seeds, the grass stems andthe grass roots cannot be eradicated can be effectively solved, the trouble of weeds to farmers is fundamentally solved, and higher popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of farmland weeding, in particular to a farmland weed killer.

Problems solved by technology

[0005] In view of the above-mentioned existing problems, the present invention aims to provide a farmland weed killer, which is provided with a stem and leaf processing device, a grass root collecting device, and a killing device in turn along the forward direction of the car body toward its rear, and the stem and leaf processing device and the grass root collection device are all connected with the killing device, and the weed killer collects the grass seeds, grass stems and grass roots according to their own characteristics, and then carries out killing treatment respectively, which solves the problem of spraying herbicides at present. The greater damage caused by the soil, the high cost of manual weeding, and the problem of secondary growth due to the inability to completely kill the grass roots and seeds during the process of mechanized weeding
