Cutting device of adjustable heading type vegetable harvesting machine

Abstract

The invention relates to a cutting device of an adjustable heading type vegetable harvesting machine. The cutting device of the adjustable heading type vegetable harvesting machine comprises a fixingmechanism, a transmission mechanism mounted on the fixing mechanism, and a connecting mechanism hinged to the fixing mechanism, wherein the connecting mechanism is fixedly connected with an underframeof a harvesting machine lifting and conveying device; and an adjusting mechanism for driving the fixing mechanism to rotate around a horizontal hinged shaft is further mounted on the underframe of the harvesting machine lifting and conveying device. According to the cutting device of the adjustable heading type vegetable harvesting machine provided by the invention, through rotating a handle, a cutting angle between a circular disk cutter and heading type vegetable rootstalks can be adjusted according to the actual working conditions, so that effective cutting is realized; through changing the rotate speed of a cutter motor of the transmission mechanism, the rotate speed of the circular disk cutter can be changed, so that the cutting efficiency and the cutting quality are improved; through replacing the type of the circular disk cutter at the actuating end of the transmission mechanism, the cutting energy consumption can be reduced, and the cutting counter-acting force is reduced, andthe complete and accurate cutting can be realized, the damage to vegetable during the cutting process can be reduced, meanwhile, the cutting efficiency can be improved, and the heading type vegetableis efficiently harvested in a low-loss way.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to the field of harvesting and cutting of head vegetables, in particular to a cutting device of an adjustable head vegetable harvester. Background technique [0002] In recent years, the total production of vegetables in my country has surpassed food crops, becoming the largest agricultural product, and this trend will continue in the future. Heading vegetables are the main types of vegetables in our country. In most areas of our country, the harvesting of head vegetables is still done manually. Although there are already head vegetable harvesters in a few areas, most of the work processes of the existing harvesters are first. Cutting after pulling out, this working method causes greater damage to the vegetables, and the cutting effect is not ideal. With the continuous improvement of people's cognition level and the continuous development of science and technology, the mechani...
