A swing type weeding manipulator between seedlings

Abstract

The invention belongs to the technical field of modern intelligent agricultural equipment, and particularly relates to a swinging type mechanical hand for weeding between seedlings for an intelligent weeding robot. The invention aims at providing the swinging type mechanical hand for weeding between the seedlings, and the swinging type mechanical hand for weeding between the seedlings is applicable to different land and can reduce the requirement of a weeding mechanical hand on the soil texture under the condition of ensuring a greater weeding coverage rate but not increasing the control difficulty. The swinging type mechanical hand for weeding between the seedlings has the advantages that a groove cam mechanism is adopted, and the continuous rotating movement of a hydraulic motor or a motor is converted into reciprocating swinging movement, so the control is simple and easy, and the service life of hardware is prolonged; a double-side-groove cam mechanism is adopted, through designing the double-side-groove cam outline curve, two weeding cutters can do identical-speed symmetrical movement, and the coverage rate of the weeding cutters between the seedlings is ensured under the condition of limited protection regions; rotary weeding cutters are converted into swinging type weeding cutters, the relative movement between the weeding cutters and the soil is reduced, and the work condition of the weeding cutters is improved; the processing and the installation are convenient, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of modern intelligent agricultural equipment, and in particular relates to a swing type inter-seedling weeding manipulator of an intelligent weeding robot. Background technique [0002] Weeds in farmland are one of the major disasters in agricultural production. Traditional manual weeding has been the main way of weeding for a long time, but manual weeding is labor-intensive, inefficient and time-consuming. Chemical weeding is now used on a large scale, successfully freeing labor from manual weeding activities. However, chemical weeding is greatly affected by the weather, and it brings serious problems such as weed resistance and ecological environment pollution. [0003] Mechanical weeding avoids environmental and food safety problems caused by chemical weeding, and has higher work efficiency. At present, intelligent mechanical weeding, as one of the key technologies of precision agricultural conservation...

Problems solved by technology

The tooth claw type realizes weeding and seedling avoidance by controlling multiple weeding claws to extend in and out between crop seedlings, and the control is more complicated

The rotary type controls the rotation of the disc weeding knife with a notch, and controls the position of the notch to avoid seedlings and weeding. The control is relatively simple. Higher coverage, but this structure is easy to break the cutter head due to stones, so its scope of application is limited to sandy land or land with few rocks
