Description

A self-propelled cabbage harvester

Technical field

The invention belongs to the technical field of cabbage harvesting, and specifically relates to a self-propelled cabbage harvester.

Background technique

As a kind of vegetable, cabbage has a huge planting area and output, accounting for a large proportion of all vegetables. Traditional cabbage harvesting is usually done by manually cutting the plants from the surface of the land with a sickle, and then manually picking and removing leaves. Manual packing has low labor efficiency and high operating costs. Currently, there is a self-propelled cabbage harvester that uses mechanized harvesting. It is composed of a self-propelled power chassis and a harvesting table assembly, which can greatly reduce labor intensity and reduce labor costs. , improve work efficiency.

When the current self-propelled cabbage harvester works, the harvesting table assembly first feeds both sides of the cabbage root through the digging shovel at a certain angle, scoops out the cabbage together with the cabbage root, and then lifts and transports it through the elevator. The double disc cutting knife cuts off the cabbage rhizomes, and finally sends the cabbage cuttings to the storage basket. When this kind of cabbage harvester is used, when the roots of the cabbage machine are shoveled out, there will be soil, and the soil will be lifted and transported by the elevator. , will stick the soil to the conveyor belt, causing the outermost layer of the cabbage to be transported to adhere to too much soil, which is not conducive to the later packaging and cleaning of the cabbage.
