The present invention relates to a spacing adjustment device for a multi-purpose harvester, and more specifically, to a transfer unit that transfers the harvested crop according to the size of the crop in the process of grasping the crop and transferring it to the discharge unit in a multi-purpose harvester capable of harvesting a variety of crops. This relates to a spacing adjustment device for a multi-purpose harvester that facilitates the transportation of crops by adjusting the left and right spacing.

In general, harvesting cabbage or green onions requires more labor than harvesting grains such as rice or barley, so mechanization is urgently needed. Specifically, the use of harvesters such as combines has already become common in grain harvesting work, but crops such as cabbage, rice or barley have lower hardness than grains, and due to the nature of leaf vegetables, they form bulbs on the ground, making harvesting very difficult and mechanizing them very difficult.

A typical cabbage harvester is a device developed to mechanize cabbage harvesting work, which had previously relied on manpower. It refers to a device that harvests planted cabbage row by row while a driver and an assistant worker ride along the field and drive along the field.

This type of cabbage harvester has a work efficiency that is about 3 to 6 times higher than that of a manual labor method, so its distribution has recently been expanding, especially among farms with large cultivation areas.

In addition, a typical cabbage harvester is largely composed of a driving part, a harvesting part, and a working part. The driving part is configured to drive the cabbage harvester, and the car body is equipped with a driver's seat for the operator in charge of operation.

In the harvesting department, cabbages are excavated and cut during transport. A structure that mainly digs up cabbage by operating it between the cabbage and the ground using a pair of rotating disc-shaped excavators, tows it with a transport belt, grasps and aligns the body of the cabbage on the transport belt, and cuts and transports the root of the cabbage with a circular blade at the tip of the transport part. It consists of The angle of the blade for cutting roots is adjustable, and a ground tracking wheel is attached to the lower side of the blade so that it can operate in response to ground irregularities.

The work department sorts the harvested cabbage and loads it into the collection tank or takes it out. In the case of a collection-type cabbage harvester, a work area is prepared for auxiliary workers in addition to the driver to load cabbage into a collection tank (box or pallet), which is the most common work method. In the case of a product-carrying type cabbage harvester, the product is transported in a small truck that runs side by side with the harvester.
