That is, when the crop A is a leaf leek (long leek such as white leek), the roots (root hairs) grow in the vertical direction (downward) in a relatively rainy season, and tend to stretch vertically and horizontally in a low rainy season. Therefore, in the midsummer dry season, in the winter dry season, the roots stretch sideways, the roots and entanglement harvest of the next green onion is heavy work, and if you forcibly pick it up, you may cut leaves and stems, etc. When the quality (including commercial value) is reduced due to breakage, the root hair or the like stretched by the vertical blade 21 is longitudinally cut to solve these problems. Furthermore, in the high-floor harvesting work vehicle according to any one of claims 1 to 4, the cutting device 4 for cutting the root hair of the crop A described above,
Vibration generator 1 for vibrating in the longitudinal direction in the soil
7 is recommended (claim 5).

As described above, by vibrating the cutting device 4 in the front-rear direction, the cutting resistance for excavation or the like can be reduced, and the softening of the soil can be promoted.

After the harvest, the loading device 6 is lowered as shown by the imaginary line in FIG. 1, while the cutting device 4 can be raised and lifted to operate lightly and easily on a general road. And FIG. 4 shows a second embodiment of the high-floor harvesting work vehicle 1 according to the present invention, in which the cutting device 4 is improved (additional configuration), and the basic configuration has already been described with reference to FIGS. Since the structure is common to the structure, reference numerals are used for common parts, and additional constituent parts will be described below exclusively.

In FIG. 4, a cutting device 4 provided at one end of the traveling machine body 3 includes a horizontal blade (cutting blade) 13 for cutting (cutting) a root hair extending downward (vertically) and a crop adjacent to the left and right. Root hairs that are entangled in the horizontal direction of A (front-back, left-right, and radial) are tangled (vertically or vertically)
And a vertical blade (straight blade) 21 that cuts (divides).
The horizontal blade 13 has a blade portion on both or one of the front and rear sides, and the vertical blade 21 may be fixed to the horizontal blade 13 at intervals in the blade longitudinal direction by welding or the like. The blade 13 holds the holder 22 at a distance in the blade longitudinal direction and slidably in the blade longitudinal direction, and adjusts and fixes the position with a fastener 23 such as a bolt. It is erected.

That is, when the crop A is green onion, the roots (root hairs) tend to elongate (grow) in the vertical direction (downward to vertical direction) in a relatively rainy season, while the rainfall is low. During the season, there is a tendency to entangle vertically and horizontally (radially in the horizontal direction), so during the dry season in midsummer and the dry season in winter, the root hairs are stretched side by side and intertwined with each other, so harvesting is heavy work, If it is forcibly pulled out, the leaves, stems, etc. will be broken or cut, and the quality will be degraded. Therefore, according to the embodiment shown in FIG. 4, root hairs extending downward are cut by the horizontal blades 13, and root hairs extending in the horizontal direction and entangled by the vertical blades 21 are cut, so that the root hairs can be used in the rainy season or the dry season. In addition, the pull-out resistance of the crop A is reduced, and breakage of the leaves and the like is suppressed, and light and reliable harvesting is enabled.

Also in the case of this embodiment, by vibrating the horizontal blade 13 and the vertical blade 21 in the longitudinal direction of the cutting device 4 by the vibration generating device 17, the cutting resistance can be reduced while the cutting action is ensured. This is advantageous because the softening of the soil can be promoted. FIGS. 5 and 6 show a third embodiment of a high-floor harvesting work vehicle 1 according to the present invention.
