Embodiment 1

[0020] The efficient weeding robot of this embodiment is as figure 1 As shown, it includes a vertical cylinder 2, a weed recognition camera 3, an automatic navigation camera 4, a herbicide application roller 5, a weed cutting roller 6, a horizontal cylinder 7, an end effector 8, and the like. In the figure, 1 represents crop 1, and 9 represents weeds. Its basic composition is: the advancement of the weeding robot relies on a four-wheel trolley, the front wheel is driven, the rear wheel is driven, and the classic McPherson suspension is used (see "Automobile Structure-Chassis Engineering" for details, published by Tsinghua University Press in March 2008, General Higher Education "Eleventh Five-Year" National Planning Textbook P185~P186, or "Automobile Structure (Volume 2) (Fourth Edition)", published by People's Communications Press in February 2002, P250~P251). The power of the robot is provided by the battery, and the vehicle embedded control system is used for identifying w...

Abstract

The invention relates to a high-efficiency weeding robot which belongs to the technical field of agricultural machinery application. The robot comprises an automatic navigation and weed identification camera head and a control system, wherein a weeding device comprises an interline cutting and smearing weeding mechanism arranged below a trolley, and an inline weeding mechanism; the cylinder bodies of a left horizontal cylinder and a right horizontal cylinder of the inline weeding mechanism are respectively arranged at the bottom of the trolley; horizontal piston rods of the left horizontal cylinder and the right horizontal cylinder are respectively and fixedly connected with installment frames of a left vertical cylinder and a right vertical cylinder; the upper ends of the installment frames of the left vertical cylinder and the right vertical cylinder are installed in horizontal rails on the trolley to form a moving pair; the cylinders of the left vertical cylinder and the right vertical cylinder are respectively installed on the installment frames of the left vertical cylinder and the right vertical cylinder; and the lower ends of vertical pistons of the left vertical cylinder and the right vertical cylinder are respectively connected with a left end effector and a right end effector the bottoms of which are provided with electric circular saws. The invention can remove weeds in lines and among lines with high working speed and high weeding efficiency, thereby radically solving the difficulty of removing weeds in lines.

Description

technical field [0001] The invention relates to an efficient weeding robot, in particular to an intelligent weeding robot capable of simultaneously removing weeds in and between rows of crops, and belongs to the technical field of agricultural machinery applications. Background technique [0002] The weeding robot, as the name suggests, is used to automatically remove weeds in the field during the seedling stage of the crops. Suitable for row-grown crops such as corn, cotton, and soybeans. In such farmland, weeds can be divided into "interrow weeds" and "intrarow weeds" according to their spatial distribution characteristics. The so-called "interrow weeds" refer to weeds that grow between two crop rows; while "intrarow weeds" refer to weeds that grow within a crop row, that is, weeds that grow on the same row as the crop. [0003] At present, chemical weeding in farmland mainly adopts spraying method. It can be applied by sprayer or by aerial application. The advantage o...
