Greenhouse leaf vegetable harvesting and root cutting manipulator with adjustable front and back positions

Abstract

The invention relates to an agricultural machine and aims to provide a greenhouse leaf vegetable harvesting and root cutting manipulator with adjustable front and back positions. The manipulator has the advantages of being reliable, stable and efficient. According to the technical scheme, the greenhouse leaf vegetable harvesting and root cutting manipulator with the adjustable front and back positions is characterized by comprising a mechanical arm, a pneumatic gripper and a cutter, wherein the pneumatic gripper and the cutter are arranged on the mechanical arm; the mechanical arm is providedwith an adjusting mechanism for driving the mechanical arm to extend and a rotating motor for driving the pneumatic gripper to rotate; the adjusting mechanism comprises a lead screw assembly, an adjusting motor driving a screw of the lead screw assembly to rotate, a guide rail parallel to the screw of the lead screw assembly, a sliding block capable of sliding along the guide rail and fixed to a nut of the lead screw assembly and a connecting plate fixed to the sliding block. The rotating motor and the cutter are arranged on the connecting plate. The cutter comprises a cutting air cylinder anda cutting tool driven by the cutting air cylinder.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a manipulator for harvesting leafy vegetables in a greenhouse with adjustable front and rear positions. Background technique [0002] With the development of population aging, the labor force that can be engaged in agricultural planting and harvesting is becoming more and more tense, and the development of agricultural machinery automation can effectively alleviate the severe situation of labor shortage. Picking machinery is the main component of agricultural machinery. The picking machinery for various crops has achieved gratifying results, and many picking machinery have been put into practical application. At present, in order to increase production and prevent pests, many vegetable greenhouse factories have been built, and the planting of vegetables has realized industrial mass production. Among them, planting leafy vegetables through hydroponic tanks is a relatively mature technolo...

Problems solved by technology

At present, in order to increase production and prevent pests, many vegetable greenhouse factories have been built, and the planting of vegetables has realized industrial mass production. Among them, planting leafy vegetables through hydroponic tanks is a relatively mature technology, but the leafy vegetables grown in hydroponic tanks are mainly Through manual harvesting, the vegetable roots need to be cut off after harvesting, the workload is large and the efficiency is low, and further improvement is needed
