Hexa-claw executing mechanism of weeding robot

Abstract

The invention belongs to the field of the agriculture robots, which is composed of shell, main shaft turntable system, cutter knife shaft system and steel wire slider bar system, the shell is fixed on the plat form of the harvested robot, the electrical motor drives the rotation of main shaft turntable system, six sets of cutter knife shaft systems rotated accompanied with the main shaft turntable system. When one set of cutter knife shaft system rotates to the side of the plants, the concave lock scotch block on the shaft system and the convex lock scotch block on the steel slider bar system are engaged and then locked, which makes the overhang of the cutter knife protrude into the lines of plants to complete the weeding action. When the space between two plants is too small, another electrical motor pulls the steel wire to lift up the convex lock scotch block on the steel slider bar system, then the concave lock scotch block can not engage with the convex lock scotch block, which makes the cutter knife not protrude into lines for preventing damage to plants by cutting. Through the coordination between master action of the master shaft and the slave action of the steel wire, the weed arbitrary action of six sets of cutter knifes in the lines and between the lines and the control thereof are realized, the weed action is continuous, the overall size is compact, the operation is flexible, and the control and operation of the weeding robot are easy.

Description

technical field [0001] The invention relates to the field of agricultural robots, in particular to a six-claw actuator of a weeding robot. Background technique [0002] In order to get rid of the heavy manual labor of weeding in the field and overcome the harm caused by chemical weeding methods, mechanized and intelligent weeding has become the direction of plant protection development. Among them, the removal of weeds between the plants in the row must be completed by an intelligent weeding robot. Currently seen weeding mechanisms, such as the rakes of companies such as Einbock, Lely, and Rabe Werk, the rotary weeder of Bezzerides, the rotary hoe of Yetter, the Danish spike weeder of Kongskilde, etc. (Jed Colquhoun and Robin Bellinder. New Cultivation Tools for Mechanical Weed Control in Vegetables; Robin Bellinder. Cultivation Tools for Mechanical Weed Control in Vegetables; Marie-Josée Hotte, et al. Use of mechanical cultivators for market vegetable crops.), are designed...

Problems solved by technology

The above weeding mechanisms cannot meet the needs of in-row weeding in general cultivation methods, let alone realize the needs of in-row and inter-row integrated weeding
