で引き抜かれる。Next, the operation of harvesting the root vegetable K with the above configuration will be described. In the embodiment, root vegetables K such as carrots vegetated in a row in a field are harvested row by row. The operator sits on the driver's seat 5, drives the engine 6, and moves the traveling machine 1 forward. Meanwhile, when the piston rod of the hydraulic cylinder 26 is retracted, the subsoiler body 25 is pushed into the ground at the position of the row to be harvested, and the operator operates the steering handle to adjust the direction of the traveling machine body 1, and the pair of left and right is pinched. The pair of left and right starting end wheels 11, 11 around which the endless belts 3, 3 are wound, is positioned so as to be located in the row of the root vegetables K on the undigged side. As the traveling body 1 advances, the foliage tine 15 at the lower end of the divider 16 ascends to separate the foliage of the root vegetable K to be dug up and the foliage of the root vegetable K on the undigged up side so as not to be entangled. . Further, the subsoiler body 25 which swings up and down by the eccentric rotating boss at the base of the upper link 22 loosens the subsoil and digs up the roots of the root vegetables K in the row to be harvested. Next, by the rotation of the scraping tine 17 of the stem and leaf scraping device 14, the foliage is raised above the upper edge of the endless bands 3, 3. At the position of the starting wheels 11, 11 of the pair of left and right endless belts 3, 3, the raised foliage is started to be pinched, and the pair of pinched endless belts 3, 3 is moved by the traveling body 1.
Is arranged so as to rise toward the rear of the root, so that the root of the root vegetable K with the foliage sandwiched is pulled out from the field with a light force.

An edge on the rake action side of the case,
The divider is located closer to the excavated side than half of the gap between the divider and the side cover. With this configuration, the inactive area protruding from the action area that rakes the foliage can be reduced by moving the rake tine at the lower end of the foliage raking device, and the foliage of root vegetables such as ginseng can be reduced. The part hanging down in the field scene is more likely to be caused by the rake tine, and since the inactive area does not overlap with the left and right centers of the tips of the pair of left and right endless bands, the raised foliage is caused. This has an effect that the pair of endless belts can be easily brought to the distal end side.

で引き抜かれる。Next, the operation of harvesting the root vegetable K with the above configuration will be described. In the embodiment, root vegetables K such as carrots vegetated in a row in a field are harvested row by row. The operator sits on the driver's seat 5, drives the engine 6, and moves the traveling machine 1 forward. Meanwhile, when the piston rod of the hydraulic cylinder 26 is retracted, the subsoiler body 25 is pushed into the ground at the position of the row to be harvested, and the operator operates the steering handle to adjust the direction of the traveling machine body 1, and the pair of left and right is pinched. The pair of left and right starting end wheels 11, 11 around which the endless belts 3, 3 are wound, is positioned so as to be located in the row of the root vegetables K on the undigged side. As advancement of the vehicle body 1, as in the upward movement of the lower end of the minute grass tines 15 of the divider 1 4, not tangled and foliage of root vegetable K to dig, and foliage of it from the non-digging-side root K separation I do. Further, the subsoiler body 25 which swings up and down by the eccentric rotating boss at the base of the upper link 22 loosens the subsoil and digs up the roots of the root vegetables K in the row to be harvested. Then, at the rotation of the scraping tine 17 of the foliage scraping device 1 6, foliage is caused above the upper edge of the clamping endless belt 3,3. At the position of the starting wheels 11, 11 of the pair of left and right endless belts 3, 3, the raised foliage is started to be pinched, and the pair of pinched endless belts 3, 3 is moved by the traveling body 1.
Is arranged so as to rise toward the rear of the root, so that the root of the root vegetable K with the foliage sandwiched is pulled out from the field with a light force.

An edge on the rake action side of the case,
The divider is located closer to the excavated side than half of the gap between the divider and the side cover. With this configuration, the inactive area protruding from the action area that rakes the foliage can be reduced by moving the rake tine at the lower end of the foliage raking device, and the foliage of root vegetables such as ginseng can be reduced. The part hanging down in the field scene is more likely to be caused by the rake tine, and since the inactive area does not overlap with the left and right centers of the tips of the pair of left and right endless bands, the raised foliage is caused. This has an effect that the pair of endless belts can be easily brought to the distal end side.
