Description

CABBAGE HAVESTER WITH STANDING DEVICE

The present invention relates to a cabbage harvester equipped with a standing device, and more specifically, to a cabbage harvester equipped with a standing device which, during the process of harvesting cabbage with its roots and then transporting it, stands the cabbage upright and accurately cuts the root portion of the standing cabbage, thereby obtaining cabbage with its roots completely cut off.

In general, harvesting crops such as cabbage and 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 widespread for grain harvesting, but cabbage is very difficult to harvest because it is a leaf vegetable with a low hardness compared to grains such as rice or barley, and it forms a knot on the ground due to its nature, making mechanization very difficult.

A conventional cabbage harvester is a device developed to mechanize the cabbage harvesting work that had previously been dependent on manpower. It refers to a device in which a driver and assistant ride in the vehicle and drive along the field to harvest the planted cabbages one row at a time.

These cabbage harvesters are currently being widely used, especially in farms with large cultivation areas, as they are about 3 to 6 times more efficient than manual labor.

And, a typical cabbage harvester is largely composed of a driving section, a harvesting section, and a working section. The driving section is configured to drive the cabbage harvester, and the body is provided with a driver's seat for the worker in charge of operation.

In the harvesting section, the roots of the cabbage are cut and harvested at the same time and transported to the working section. It is mainly done by operating a pair of rotating disk-shaped blades between the cabbage and the ground to cut the roots of the cabbage, and at the same time, the body of the cabbage is crushed by a conveying belt and transported to the working section. The blade for cutting the roots can be angle-adjusted and a ground-following wheel is sometimes attached to the lower part of the blade so that it can operate in response to ground irregularities.

The work section sorts the harvested cabbages and loads or removes them from the collection tank. In the case of the collection type cabbage harvester, a work area is provided for an assistant worker to ride in addition to the driver, and the cabbages are loaded into the collection tank (box or pallet), which is the most common work method. In the case of the product removal type cabbage harvester, the products are transported to a small truck that runs alongside the harvester.

Meanwhile, Japanese Patent Publication No. 3636781 discloses a cabbage harvester comprising a harvesting unit that harvests vegetables at the front of the main body and returns the harvested products through the upper part of the main body to a receiving unit located at the rear of the main body, a working unit arranged at one side of the main body, and a driving means that drives the harvesting unit and the driving device with a single power source, and the harvesting unit is provided with a means for cutting and processing the root portion of the harvested products.

However, the above-mentioned conventional cabbage harvester has a problem in that it is structured to transport the cabbage by closely contacting both sides of the cabbage, so that the cabbage may be transported without standing up properly, and as a result, the root portion may not be cut reliably.

Meanwhile, registered patent No. 10-1802405 proposes and discloses a cabbage harvester equipped with a driving unit, a harvesting unit, and a working unit for harvesting cabbages while driving through a field, including a lower transport unit having a lower squeezing belt that rotates symmetrically on both sides, and an upper transport unit having an upper squeezing belt that rotates symmetrically on both sides and is mounted at a predetermined height above the lower transport unit; the lower transport unit and the upper transport unit are equipped with a lower drive unit and an upper drive unit that are linked to a hydraulic pump that drives the driving unit, and the working unit is equipped with a control lever that controls the individual driving speeds of the lower drive unit and the upper drive unit, thereby configuring the lower and upper parts of the cabbage to stand vertically on the lower transport unit and the upper transport unit and pass through the cutting unit, thereby having a squeezing posture correction function that can significantly improve the cutting quality and workability of cabbage roots.

Patent registration No. 10-1833185 proposes and discloses a walking cabbage harvester having an electrically driven cabbage harvesting device, a cabbage collection box, an internal combustion engine-type alternator, a cabbage harvesting device control box, a wheeled electric vehicle, and a driver's handle, and wherein the cabbage body transport speed and the cabbage root transport speed of the front upper belt, the rear upper belt, and the front lower belt, and the gap between the front upper belt, the rear upper belt, and the inclination angle of the cabbage harvesting device cause the cabbage to be positioned perpendicular to the root cutting disk at the position of the root cutting disk installed on the left and right, so that the roots of the cabbage and the outer leaves of the cabbage, which are not marketable, are cleanly cut.

Patent Registration No. 10-18386947 relates to an invention regarding a cabbage harvester having a root cutting height adjustment function, wherein the cabbage harvester is equipped with a driving unit, a harvesting unit, and a working unit to harvest cabbage while driving on a field, wherein the harvesting unit is provided with a gripping unit, a lower conveying unit, an upper conveying unit, and a cutting unit provided at a lower portion on the path of the lower conveying unit to cut the roots of the cabbage being conveyed; and the cutting unit includes a blade formed in a '∨' shape with respect to the direction of transportation of the cabbage and mounted on a support means so as to be parallel to the inclination angle of the lower conveying unit, a detection means provided on one side of the blade to detect the roots of the cabbage and detect the position, and a height adjustment means for automatically raising and lowering the height of the blade in conjunction with the detection means, thereby significantly improving the cutting quality and workability of the cabbage roots, and a cabbage harvester having a root cutting height adjustment function is proposed and disclosed.
