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.
