Cutting device for stem and leaf vegetable harvester

Abstract

The invention relates to a cutting device for a stem and leaf vegetable harvester. The cutting device is composed of an annular-belt-shaped tooth-shaped cutting knife, a cutting knife driving wheel, a cutting knife driven wheel, a supporting wheel and a tensioning wheel, wherein the cutting knife driving wheel, the cutting knife driven wheel, the supporting wheel and the tensioning wheel are mounted on a main cutting table frame and distributed quadrilaterally; the annular-belt-shaped tooth-shaped cutting knife bypasses the cutting knife driving wheel, the cutting knife driven wheel, the supporting wheel and the tensioning wheel and is driven by the cutting knife driving wheel to perform circulation reciprocating motion; the cutting device is characterized in that the diameters of the supporting wheel and the tensioning wheel are far smaller than those of the cutting knife driving wheel and the cutting knife driven wheel. Meanwhile, the positions of axes of three of the cutting knife driving wheel, the cutting knife driven wheel, the supporting wheel and the tensioning wheel are adjustable. The cutting device is relatively smaller in size and relatively low in cost; meanwhile, since the positions of the axis of three wheels can be adjusted timely, the distance between the upper part and the lower part of the annular-belt-shaped tooth-shaped cutting knife can be changed conveniently, therefore, vegetables of different heights can be harvested.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a cutting device for a stem and leaf vegetable harvester. Background technique [0002] The stem and leaf vegetable harvester is composed of a frame with a walking mechanism, a power system, a cutting device, a conveyor belt, a turnover box, and a control system. The cutting device is installed at the front end of the conveyor belt for harvesting vegetables, and the turnover box is installed on the On the rear side of the conveyor belt, the vegetables harvested by the cutting device are transported to the turnover box by the conveyor belt; the power system provides power for the traveling mechanism, the cutting device, and the conveyor belt. [0003] In the prior art, the cutting device is composed of a ring-shaped toothed cutter, a cutter driving wheel, a cutter driven wheel, a supporting wheel, a tension wheel, and the main frame of the cutting table. The drivin...

Problems solved by technology

[0004] The deficiencies in the prior art are: 1. The cutter driving wheel, the cutter driven wheel, the supporting roller and the tensioning wheel have the same diameter, and the overall volume of the cutting device is large and the cost is high; The distance is a fixed value, and the ring-shaped toothed cutter can only harvest vegetables at the same height, which has poor adaptability; it needs to be improved
