Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root crop harvester for digging root crops such as radish.

[0002]

2. Description of the Related Art If it is a manual work to dig and harvest root crops such as radish, it is very hard work because the worker has a bent work posture for a long time. Therefore, before digging, a radish harvester has been developed as a tractor-mounted type in which the ridges are softened with excavation claws and then the foliage of the radish is sandwiched between a pair of pulling belts on the left and right to pull out.
(Refer to pages 869 to 870 of the new edition Agricultural Machinery Handbook).

[0003]

In the conventional harvesting machine, when harvesting radish which is cultivated in multi, it is difficult to work because the multi-film catches on the excavating claw preceding the pulling belt. On the other hand, if the multi-film between the ridges is cut with a coulter or the like prior to the excavating claw, the foliage that is hanging down between the ridges will also be cut, and in this case, the subsequent extraction is performed by sandwiching the foliage. In addition to the difficulty in pulling out, when pickled radish and the like are dried in the sun, it is difficult to bind the foliage with a string.

Therefore, the present invention provides a root vegetable crop in which the multi-film on the furrows is cut and pierced after the radish is pulled out to reduce the catch of the multi-film on the excavating nails and to prevent foliar cutting. The purpose is to provide a harvester.

[0005]

The present invention is provided with an excavating claw 10 for expanding and softening a ridge B on which a root vegetable crop A is planted, and the excavating claw is provided by a pair of left and right pull-out belts 11 and 12 inclined rearward and upward. In a root vegetable crop harvester in which a root vegetable crop A of ridge B softened in 10 is sandwiched and pulled out, the following technical measures are taken to achieve the above-mentioned object.

That is, according to the present invention, the cutting tool 26 of the multi-film C, which is covered on the ridge B, is attached to the pull-out belts 11,1.
Furrow B that is behind the withdrawal start end of 2 and is adjacent to the excavation claw 10
It is characterized in that it is equipped relative to 2.

[0007]

[Function] When harvesting the root crop A, the ridge B is used with the excavating nail 10.
After swelling, the foliage a of the crop A is pinched from both sides by a pair of left and right pulling belts 11 and 12, and the crop A is pulled upward from the ridges B while being fed relatively backward. At this time, the excavation claw 10 passes through the furrow B1 having the edge C1 of the multi-film C covered over two ridges, and the multi-film C
The cutting tool 26 passes through the ridges B2 in the continuous part C2 of the above, and the continuous part C2 is cut by the cutting tool 26 or after the crop A is withdrawn.

Therefore, in the next harvest, even if the excavating claw 10 passes through the continuous portion C2, the continuous portion C2 is divided, so that the film C is not caught or dragged.
