Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foliage transfer device of a crop extractor for extracting foliage upwards from a crop cultivated along a soil surface formed on a ridge, and it relates to potatoes, root vegetables and beans. It can be used for harvesting.

[0002]

PRIOR ART AND PROBLEM TO BE SOLVED BY THE INVENTION The foliage of the crop planted in the ridge is expanded so that the foliage of the crop is spread across the right and left sides of the ridge. With a crop puller that pulls out this crop while it is scraped by the rotation drive of the belt with a pull-in lug, the stalk of this crop is taken over between the endless bodies of the pulling device and moved to the rear upper part, The foliage of the crop to be transferred to the upper part may be caught on the upper side surface of the frame that supports the drive shaft on the upper side that rotationally drives the drawn endless body, and it may not be transferred to the upper part by the smooth. Yes, we are trying to eliminate this.

[0003]

According to the present invention, a stalk of a crop (a) is held between a pair of left and right drawn endless bodies 9 and is transferred to an upper rear portion from the ridge (b) to the crop (a). A) withdrawing devices 6 and 6 and a pair of left and right belts 17 and 17 with a scraping lug 16 which are located in the front upper part of the extracting device 6 and engage and scrape the foliage of the crop (a). Along with
A scraping device 7, 7 is provided in which the scraping part 21 at the lower end portion is opened and spread so as to straddle both left and right sides of the ridge (b), and the crops ( (1) A foliage transfer device for a crop extractor, characterized in that transfer devices (8, 8) for holding the stalk portion between a pair of left and right transfer endless members (22, 22) and transferring it to the rear upper part are provided. .

[0004]

Action and effect of the invention: The endless body 9 of the crop (a) planted in the ridge (b) and the belt 17 with the left and right scraping lugs 16 and the pulling devices 6 and 6 on the upper part of the ridge (b). , 9 are straddled and the aircraft is advanced. The foliage of this crop (a) has belts 17 and 17 with the scraping lug 16 of the scraping part 21 at the lower end of the scraping device 7 and 7 that spreads the ridge (b) across the left and right sides. It is scraped by the rotation drive of
Between the endless bodies 9 and 9 of the pulling devices 6 and 6, the foliage part of the crop (a) is taken over and moved to the rear upper part to be pulled out. The transfer devices 8 and 8 are transferred between the endless transfer members 22 and 22 while being held between them.

Thus, the crop (a) is pulled out by the pulling devices 6,6.
The transfer endless bodies 22, 22 are forcibly handed over to the rear upper part by being carried over between the transfer endless bodies 9, 9 and transferred to the transfer endless bodies 22, 22 of the transfer device 8, 8. The crop (a) will be forcibly passed over the upper side surface of the frame that rotatably drives the upper drive shaft that rotationally drives the pulling-out endless bodies 9 and 9. , This withdrawn crop (a) is no longer stagnant. Further, for example, the stagnation can be eliminated by making the peripheral speed of the transfer endless bodies 22, 22 higher than the peripheral speed of the drawn endless bodies 9, 9.
