[0007]

Means for Solving the Problems [Structure, operation and effect of the invention according to claim 1]

(Structure) According to the first aspect of the invention, the locking claw is protruded forward, and is moved obliquely rearward and upward from the vicinity of the ground to pull up the root stem of the root vegetable in the field. A turn-type leaf stem pulling device is placed on both left and right sides of the root vegetable strip, and the leaf stem pulled up by this leaf stem pulling device is tilted rearward and obliquely upward with the locking claws protruding sideways. A side-turning type leaf stem lifting device that is moved toward and scraped up is provided behind the leaf stem lifting device,
A root crop harvesting machine configured to pinch and convey a leaf stem picked up by this leaf stem raising device by a pinch pulling and conveying device toward a rear obliquely upward direction, in a ridge on which a multi-sheet is hung. Near the skirt of the furrow shoulder, deploy the crusher body that enters the lower part of the root vegetable planted in the ridge from the vicinity of the ridge shoulder and is driven back and forth to the side of the fuselage, and near the skirt of the ridge shoulder at the position immediately in front of this crusher body. , Deploying a sheet flip-up assisting device to make the hem of the multi-seat hung on the ridge free and flip up, and
A multi-holding body acting on the upper surface of the multi-seat is provided.

(Action) According to the above configuration, as the body advances along the ridges, first, the vertical-turning type leaf stem pulling device pulls up the root stems of root vegetables to be harvested, and then the leaf stems are moved horizontally. It is picked up by the turning type leaf stem pick-up device, guided to the starting end of the pinch pulling and conveying device, and pinched and conveyed obliquely rearward and upward by the pinch pulling and conveying device. In addition, on the lateral side of the portion corresponding to the holding start end portion of the holding / pulling-up conveyance device, first, the sheet-turning-up assisting tool moves forward while acting near the skirt of the ridge shoulder, thereby covering the skirt of the multi-sheet. The soil that has been destroyed or removed is removed, and the hem of the multi-seat is turned up and is in an easy state. Continuously, the soil breaker enters the lower part of the root vegetable main body from near the skirt of the ridge shoulder through which the sheet turning aid has passed, moves forward and back and forth, and moves forward and softens the soil near the root vegetable planting . At this time, since the hem of the multi-seat is in an easy-to-turn-up state by the passage of the sheet-turning-up assisting tool, the crushing body pushes the hem of the multi-seat up and down without difficulty.

In addition, the multi-sheet becomes an obstacle to pulling the whole root vegetable from the ridge covered by the multi-sheet, but if the perforation or cut is made in advance in the planting hole of the multi-sheet, the root plant body can be easily broken by breaking the planting hole. It can be passed through, and the whole root vegetables can be extracted.

[0011] In this harvesting mode, when the crushed sheet advances while turning up the hem of the multi-sheet, if the multi-sheet becomes slack, the crushed sheet is more likely to catch on the multi-sheet. In addition, when the root vegetables are pulled out from the ridge or when the leaf stem is pulled up by the leaf stem pulling device, the root vegetable body is caught on the multi-sheet, and the multi-sheet portion around the root is lifted widely, and the perforation is perforated. Although the cut may not be cut well, the above-mentioned problem can be avoided by disposing the multi-holding member in an appropriate position to prevent the multi-sheet from being lifted.

[0012] In the second harvesting mode, the leaf stem protruding from the multi-sheet is cut and transported as it is immediately after being clamped by the clamping / pulling-up conveyor, and then the leaf stem is cut and removed. The multi-sheet is flipped up and removed, and the root vegetables remaining on the ridge are collected. In this case, since the soil around the root vegetable main body left on the ridge is swelled and softened by the soil breaking body, the root vegetable main body can be easily pulled out and collected. In this embodiment, it is not necessary to make perforations or cuts in advance in the planting holes of the multi-sheet.

[0013] Also in this harvesting mode, the multi-sheet is lifted up by the leaf-stalk pulling-up device, and the multi-sheet is lifted up for continuous work. Although it may become difficult, continuous work becomes possible by arranging the multi-holding body in an appropriate position to prevent the multi-sheet from being lifted up.
