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]

2. Description of the Related Art The upper part of the foliage of a crop planted in a ridge is cut by a chopper and discharged to a predetermined position on the surface of the field, and the foliage remaining in the ridge is removed. This crop is scraped by the rotation driving of the belt with the scraping lug of the scraping part of the scraping device that spreads this ridge across both left and right sides, and from the sandwiching start end part between the pulling endless bodies of the pulling device. In a crop pulling machine that pulls out this crop while taking over the stalk of the crop and transporting it to the upper rear part, the crop may fall out from between the drawn endless bodies. Even if there is a pinching error, it is intended to ensure the transfer by a structure that can eliminate this error.

[0003]

According to the present invention, a pair of left and right upper pull-out endless bodies 29, 29 between an upper holding start end portion 34 and a lower pull-out endless body 37, 37 between a lower holding start end portion 43 are used for crop (a). Upper pulling device 28, 2 for pulling the crop (a) from the ridge (b) while nipping the stalk of
8 and the lower drawing device 36, 36, and the upper drawing device 28
It has a pair of right and left belts 22 with a scraping lug 21 for engaging and scraping the foliage of the crop (a) at the upper part of the front position, and the scraping part 27 at the lower end of the ridge ( (B) The scraping device 20, 20 opened and spread so as to straddle both left and right sides of
Is provided, and a chopper 6 for cutting the upper part of the foliage of the crop (a) is provided on the front upper part of the scraping device 20, and the upper drawing endless body 29, 2 is cut from the lower end 35 of the chopper 6.
The upper clamping start end portion 34 between 9 is positioned lower, and the lower clamping start end portion 43 between the lower pull-out endless bodies 37, 37 is positioned lower than the clamping start end portion 34. The foliage transfer device of the crop extractor is used.

[0004]

[Operation and effect of the invention] The upper part of the foliage of the crop (a) planted in the ridge (b) is cut by the chopper 6 and discharged into the groove between the ridge (b) and (b) in the field. To be done. The stems and leaves remaining in the ridge (b) have the upper endless body 29 of the upper part of the ridge (b) with the belts 22 and 22 with the scraping lugs 21 of the scraping device 20 on the left and right sides and the upper pulling devices 28 and 28. , 29 and the lower pull-out devices 36, 36 so that the lower pull-out endless bodies 37, 37 straddle each other, and the forward movement of the machine causes the foliage portion to spread and spread across the ridge (b) left and right. The scraping lug 21 of the scraping portion 27 at the lower end of the scraping device 20, 20.
It is scraped by the rotational drive of the attached belts 22 and 22, and the foliage portion of this crop (a) is taken over and sandwiched at the upper sandwiching start end portion 34 between the upper stripping endless bodies 29 and 29 of the upper stripping devices 28 and 28. And is pulled out while being transferred to the rear upper part, and is further clamped by the clamping start end portion 43 between the lower pull-out endless bodies 37, 37 of the lower pull-out device 36, 36, and is transferred to the rear upper part and at the same time, the upper pull-out endless body. The stems and leaves that have not been extracted by 29, 29 are further clamped by the lower clamping start end 43 of the lower withdrawal endless bodies 37, 37, withdrawn and transferred to the rear upper part, and sequentially from the end to a predetermined position on the field surface. Is discharged.

Due to the above, the foliage portion is the upper pulling device 2
By both 8, 28 and the lower pulling device 36, 36,
Since the lower part is clamped and transferred, the foliage is prevented from falling off, and the upper pulling device 2 on the front side is removed.
Even if it is not pulled out without being pinched by 8 and 28, the pinching error is reliably eliminated by being pinched and pulled out by the lower pulling devices 36 and 36 on the rear side. Furthermore, the cutting position and the clamping position are on the rear side in the traveling direction,
Since they are located in the lower order, the drawing accuracy is greatly improved.
