Efficient weeding method for wheat field

Abstract

The invention discloses an efficient weeding method for a wheat field, which comprises a weeding vehicle and comprises the following steps: S1, adjusting the posture of a supporting arm by the weeding vehicle; s2, acquiring image information of weeds in the advancing direction through a weed detection device at the front part of the frame, judging attributes of the weeds, and determining root positions of the weeds; s3, after the weeding vehicle stops moving, unit weeding ranges are formed, a mapping relation is formed between the weeding mechanisms and the unit weeding ranges, it is determined that the closest weeding mechanism is positioned to the roots of the weeds, and closed fixed-point high-pressure impact, pulling and root grinding operation is sequentially conducted on the roots of the weeds. The weeding vehicle is used for weeding a wheat field, the gravity center of the weeding vehicle is adjusted through the supporting arm, the posture of the weeding vehicle is adjusted, and then the weeding vehicle moves or turns in the nematic arrangement direction; the weed detection device is arranged in front of the frame, so that the purpose of detection in advance is achieved, the image processing time is shortened, and the purpose of efficient weeding is achieved.

Description

technical field [0001] The invention relates to the technical field of weeding, in particular to a high-efficiency weeding method for wheat fields. Background technique [0002] In order to realize the green and pollution-free growth of wheat throughout its life cycle, weeds in wheat fields need to be removed. The emergence of automatic weeding devices in the prior art can not only replace human beings to complete boring and repetitive agricultural operations, but also efficiently and continuously operate in different outdoor environments, and can also improve production efficiency and effectively free human hands. [0003] However, the existing automatic weeding device has the following problems: 1. It is difficult to adjust the posture of the weeding device; 2. The ears of wheat are easy to block the weeds, and it is difficult to locate the weeds, and the automatic weeding device cannot achieve weeding. Weed positioning and weeding operations are carried out immediately i...

AI Technical Summary

Problems solved by technology

The invention uses the weeding vehicle to walk and weed in the wheat field, adjusts the center of gravity of the weeding vehicle through the support arm, and solves the problem that the adjustment of the posture of the weeding vehicle cannot be performed in the prior art

In the present invention, the vehicle frame is arranged above the wheat on both sides, and the weed detection device is arranged on the front lip of the vehicle frame, so as to solve the problem that it is difficult to locate weeds in the prior art, and the problem of weed location and weeding is solved. operation time delay

Using the structure of the mechanical web and the cooperation of the flexible tube, the soil at the roots of the weeds can be loosened, which solves the problem of difficult removal of weeds with deep roots.

Utilize the support arms on both sides of the frame to span two rows of wheat, adapt to the dense planting arrangement of wheat in the wheat field, and solve the problem of easily crushing the wheat or causing damage to the wheat field in the prior art
