Wheat crop weeding device

Abstract

The invention relates to the technical field of wheat crop weeding devices, in particular to a wheat crop weeding device. The device comprises a moving frame, a moving plate is slidably connected to the front face of the moving frame in the vertical direction, a height adjusting device is connected between the moving plate and the moving frame, and the height adjusting device is used for adjusting the height of the moving plate. The front face of the moving plate is transversely and slidably connected with two symmetrically-arranged connecting frames. When a water diversion channel is widened, the distance between the two connecting frames can be adjusted through an indirect adjusting mechanism, two connecting plates are synchronously driven to adjust the distance, first straight grass cutters between the two connecting plates move along with the moving plate, and the two first straight grass cutters arranged at an interval transversely deviate. The cutting range of overturning cutting of the whole first straight grass cutters is increased, the problem of cutting missing in the rotary weeding process in the whole weeding process is solved, adaptive adjustment can be conducted according to changes of the drainage channel, and use is convenient.

Description

technical field [0001] The invention relates to the field of wheat crop weeding devices, in particular to a wheat crop weeding device. Background technique [0002] Before wheat planting, if the weeds in the planting field are not removed, the growth of these weeds will absorb a large amount of nutrients in the planting field, which will seriously affect the growth of wheat and cause poor growth. Therefore, before wheat planting , we need to weed the planting area first. [0003] The prior art discloses some patent documents related to the weeding device. The Chinese patent application number 202022509823.0 discloses a weed weeding device for wheat planting, including a bracket, a handle, a cutting wheel, a roller and a servo motor. The handle rotates Connected to the side of the bracket, the cutting wheel is rotatably connected to the lower side plate of the bracket, the roller is fixedly connected to the left and right sides of the lower end of the bracket, the servo moto...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when weeding the wheat field, the size of the diversion channel opened in the wheat field changes spatially due to the impact of rain in rainy days or long-term soil sedimentation, and the size of the diversion channel itself is also deviated, while the existing The structure of the weeding device is relatively fixed, and it is not convenient to change the weeding span according to the change of the actual diversion channel, which will cause the problem that the weeding span is not suitable and affect the quality of weeding
