There are many kinds of plants cultivated for the purpose of mankind. Among them, leek is greenish yellow vegetable which contains a lot of nutrients such as carotene, vitamin B2, vitamin C, calcium and iron. It helps digestion, And is a health food that has been popular in recent years. These leeks are strong in cold tolerance and resistance to the environment and are easy to cultivate because they are very adaptable to the environment and are cultivated in many farms.

However, it is easy to cultivate the leek, but it is troublesome to manually harvest the leek cultivated. Especially, leek is a perennial vegetable, so it needs to harvest leaves only so that its roots are not damaged.

Accordingly, in recent years, a variety of leek harvesters have been developed that can automatically harvest the leeks grown.

As an example, a conventional leeward harvester has an inclined frame, and a pair of drive wheels and a pair of knobs are installed at the center and rear of the inclined frame. The drive wheels are configured to be driven by a drive motor, which is driven by a battery mounted on the frame. The handle enables the leek harvester to be operated.

In addition, a guide for guiding the leek is provided at the front end of the frame, and a cutting blade for cutting the leek collected at the lower portion of the guide is provided. The cutting edge is driven by a cutting motor installed in the frame, and the cutting motor is driven by a battery.

In addition, the conventional leeward harvester has a conveyor device that grasps the sliced leucards and feeds them to the rear side of the frame. The conveyor device is composed of first and second belt conveyors, each of which constitutes one pair. The first and second belt conveyors comprise a drive roller provided on the rear side of the frame, a driven roller provided on the front side of the frame, a belt wound around the drive roller and the driven roller, and a drive motor for driving the drive roller do. The drive roller is installed horizontally with respect to the paper surface, and the driven roller is disposed at an angle of 90 [deg.] With respect to the drive roller, and the belt is engaged with the drive roller and the driven roller at right angles. Accordingly, the first and second belt conveyors are arranged so as to face each other and grasp the vertically cut incontinent and pull it up to the rear side of the frame. The vertically hooked belts transport the vertically cut incontinent in a horizontal state I will.

In addition, the leek harvester has a collecting barrel capable of collecting the leek transferred from the first and second belt conveyors. The collecting basin is configured to be top-gutted and stores the leek falling from the first and second belt conveyors.

When the leek harvester according to such a configuration is driven into the leek field, the leek is collected by the guide and cut by the cutting blade, and the leached leek is pulled up to the rear upper side by the conveyor device and collected in the collecting barrel.

However, the conventional leek harvester has a problem that the leek to be harvested is hidden because of the height of the frame. In this case, if you drive a leek harvesting machine in the wrong direction, it will not be possible to harvest the leek, and there is a risk of injuring the leek.

In addition, in the conventional leek harvester, since the frame is integrally formed, the height of the cutting edge changes when the driving wheel passes over the ground surface of the leech field, and thus the leaching height of the leek is uneven.

In addition, in the conventional leek harvester, the harvested leek is pulled up to the conveyor device and then dropped down to collect the collected leek in the collecting bar, and the leek harvested in the process of falling into the collecting barrel is disrupted. In this case, it takes a lot of time to bundle the leeks collected in the collection container and ship them in a certain amount.
