Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art The foliage part of a crop planted in a ridge part is swept at the lower end part of a scraping device which spreads the ridge part left and right. The crop pulling machine, which is scraped by the rotational drive of the belt with lugs, pulls this crop between the pulling endless bodies of the pulling device, while holding the stalk of this crop and transferring it to the rear upper part, for example, The work crop is potato, and if the foliage of this potato is laid down and the laid state is terrible, in order to surely scrape the foliage, it is necessary to attach the scraping lug of the scraping device. It is necessary to bring the belt closer to the ridge, and if it gets too close, the soil of the ridge will be scraped off by this rug, and this ridge will collapse, exposing the potatoes and possibly damaging them, which deteriorates the quality. There was this, but this It is intended to solve the problems.

[0003]

According to the present invention, a stalk of crop (a) is sandwiched between a pair of left and right drawn endless bodies 9 and transferred to the upper rear portion while the crop (a) is removed from the ridge (b). 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). In addition to the above, there are provided the scraping devices 7 and 7 in which the scraping part 21 at the lower end is spread over the right and left sides of the ridge (b), and the crop (a) is cut into the scraping lug 16 A pair of left and right dirt trapping prevention plates 40, 40 for preventing the ridge (b) from collapsing at the time of scraping with the attached belts 17, 17 are located at the lower front part of the scraping device 7, 7 and are rearward. A foliage scraping device of a crop extractor characterized by being provided in a predetermined length.

[0004]

Action and effect of the invention: The endless withdrawal of the belts 17 and 17 with the left and right scraping lugs 16 and the withdrawing devices 6 and 6 on the upper part of the ridge (b) of the crop (a) planted in the ridge (b). Body 9, 9
So that they straddle and move the aircraft forward. The foliage part of this crop (a) has a scraping part 21 at the lower end of the scraping device 7, 7 in which the ridge part (b) is spread across both left and right sides.
The belt 17 with the scraping lug 16 is driven to rotate, and the foliage of this crop (a) is taken over and sandwiched between the withdrawing endless bodies 9 and 9 of the withdrawing devices 6 and 6. When the foliage of this crop (a) is scraped and pulled out while being transferred to the upper part, the ridge (b) is a predetermined length toward the rear at the lower part of the front part of the scraping device 7,7. The ridges (b) are prevented from collapsing by the soil-trapping prevention plates 40, 40 provided in the above, and the protection is performed in a protected state.

As described above, when the crop (a) is potato, the ridge (b) is protected by the soil trapping plates 40 and 40 when the foliage of the potato is scraped and pulled out. As a result, the scraping lug 16 does not come into direct contact with the ridge (b), which prevents the ridge (b) from collapsing and prevents the potato from being exposed and damaged. did it.
