From the lower end of the transmission case 6 to the left and right sides,
A rotating shaft 7 is provided, which is orthogonal to the traveling direction and projects substantially horizontally.

The lower end of the rotating shaft 7 is closer to the root a of the green onion A, and the upper part is the stem of the green onion A, via the oblique shaft 8 at the shaft end on one side. b, a digging blade 9 rotating on a rotating surface inclined away from the digging blade 9 is disposed on a rotating shaft 7 near the transmission case 6 side from the digging blade 9 to remove soil excavated by the digging blade 9. A movable blade body (spiral blade) 10 for moving the blade to the side is provided. Then, as shown in FIG. 1, the excavating blade 9 is attached to an attaching portion 11 attached to the rotating shaft 7.
In contrast, a plurality (four) of support arms 12 extending at equal intervals in the radial direction are detachably provided by bolts and nuts 13, 13,..., And a sharp blade in the rotational direction is provided at the tip of each support arm 12. An outer blade 14 having an outer blade 14 and an inner blade 15 bent from the outer blade 14 in a direction intersecting the plane of rotation thereof and having a sharp blade at a tip thereof; A digging / cutting blade 16 having a sawtooth-shaped blade formed rearward in the rotation direction of 14 and having an outer periphery close to a circle as a whole is attached to the support arm 12 with bolts / nuts 17,
17 detachably provided.

The above-mentioned rotary shaft 7, excavating blade 9, and moving blade 10
Is covered with a digging portion cover 18, and a plowing depth adjusting wheel 19 for adjusting the digging depth of the digging blade 9 is provided at the rear left and right center position of the cover 18. The rotating shaft 7, the digging blade 9, and the movable blade body 10 are supported so as to rotate in the direction of the arrow in the figure.
Is designed to perform a digging operation of the green onion A by traveling with the tillage depth adjusting wheel 19 at the head in a reverse state at the time of work. Of course, it goes without saying that the digging work can be performed even when the cultivator 1 is in the backward traveling state.

In the leek digging apparatus thus constructed, when the cultivator 1 is introduced into the field and the leek digging operation is performed, the rotary shaft 7, the digging blade 9, and the movable blade 10 are moved in the direction of the arrow. The cultivator 1 is rotated, and the cultivator 1 travels slowly in the reverse state, and the lower portion of the cultivation ridge B of the green onion A is turned on by the outer blade 14, the inner blade 15, and the digging / cutting blade 16 of the digging blade 9.
Approaching the root a of the green onion, and rotating on a rotating surface whose upper part is inclined away from the stem b of the green onion A to excavate the side soil on which the green onion A is vegetated while forming a clean groove. The excavated soil is sent to the side by a moving blade (spiral blade) 10. Then, the green onion A can be easily harvested by holding the green onion A by hand and pulling the green onion so that the green onion A is slightly tilted toward the groove where the soil has been dug.

At the time of the onion digging operation as described above, the onion A
Root a is well stretched, and cultivation ridge B of green onion A

In particular, the digging / cutting blade 16 is configured so as to form a saw-like blade at an outer periphery substantially equal to the outer periphery of the outer blade 14 so as to have an outer periphery close to a circle as a whole. The onion roots a and the leaves c are cut well and the onion leaves c are reliably prevented from winding around the support arm 12 and the rotating shaft 7. Therefore, a situation in which the green onion leaves are wound around the rotating shaft and the operation for removing the green onions is interrupted does not occur. In the digging blade 9, the support arm 12 can be attached to and detached from the mounting portion 11 by bolts and nuts 13, and the digging and cutting blade 16 can be attached to and detached from the support arm 12 by bolts and nuts 17. When the outer blade 14 and the inner blade 15 are damaged, the support arm 12 itself is damaged. When the digging / cutting blade 16 is damaged, the digging / cutting blade 16 is
