DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary cutting blade of a root vegetable harvesting machine and a leaf splitting structure, in which a root vegetable is lifted up by a digging body, and the leaves are pinched and pulled up.

[0002]

2. Description of the Related Art Conventionally, root vegetables are dug up from the soil of a field by a digging body attached to a traveling machine body, and before the root vegetables settle down and tilt, the foliage is pinched, and the foliage is suspended and transported. As a root vegetable harvesting machine having a body, for example, there is a technique disclosed in Japanese Patent Application Laid-Open No. 2-49507 or Japanese Patent Publication No. 52-6207. These root crops were provided with a pair of herbaceous bodies in front of the loading section in order to sequentially guide the cultivation line of root crops to the loading section of the carrier.

[0003]

However, in the above-mentioned prior art, the foliage of root vegetables is covered in the furrows and the center of the cultivation line, so that when the excavated body towed by the traveling machine moves, the roots are cut off. The root and stem portions of the root vegetables were entangled with the body and surrounding members, causing great resistance. In addition, foreign substances and weeds also became resistance on the ground surface of the furrows, so that the root vegetable harvesting machine could not dig smoothly. Further, when the field is covered with the multi-film, the multi-film has to be cut or moved to one side before the harvesting operation, so that it is necessary to perform a troublesome operation.

Towing progresses. Then, by driving the hydraulic motor 25 with the pressure oil supplied from the traveling machine body 1, the excavating body 3 vibrates through the link mechanism 24, and the ski body 3a swings in the front-rear direction, so Root A is dug up and rises. On the other hand, the hydraulic cylinder 32 is expanded and contracted by the pressurized oil supplied from the traveling machine body 1 to adjust the vertical holding position of the carry-in portion 8 of the transport bodies 7, and the hydraulic cylinder 14 is extended and retracted to carry the transport bodies 7. The position of the portion 8 in the left-right width direction is adjusted, and the position is adjusted so as to match the foliage B of the root vegetable A that digs the carry-in portion 8 without changing the position of the conveyance bodies 7 and the horizontal conveyance belt 39.

Then, when the traveling body 1 is advanced,
At the furrow or the center of the cultivation row, the herbaceous bodies 5a and 5b push through the foliage B of the root vegetable A overlying, and the rotary cutting blades 4a and 4b cut the root so that the excavator 3 can easily dig the root vegetable A. I do. In addition, soil is multi-film C
Similarly, the rotary cutting blades 4a and 4b
Cuts the multi-film C or the like in the traveling direction, and the foliage B of the root vegetable A is guided to the carry-in portion 8 of the carrier 7 by the weeds 5a and 5c. The depth of the soil cut by the rotary cutting blades 4a and 4b is regulated by the wide ring 4c. In addition, as shown in FIG. 5, the set position of the root vegetable harvester is the excavator 3 on the right side of the traveling machine 1,
The left weeding body 5a and the rotary cutting blade 4a are moved up and down so as to face the center of the cultivation row of the root vegetable A, and the right weeding body 4b and the rotary cutting blade 4b are placed facing the ridge where the root vegetable A is cultivated. Is also good.

When the hydraulic motor 21 is started,
Conveyors 7.7 circling inward in opposite directions
Rotate backward at the same speed in synchronization with each other.
Thus, before the emerged root vegetables A sink and fall down, the foliage B is gathered at the center in the carrying-in portion 8 of the transport bodies 7.7, and is held by the transport bodies 7.7, so that the root vegetables A are suspended. Conveyed upward and rearward. Then, the lower end of the root vegetable A that is suspended and being transported comes into contact with the roller 40 and receives resistance, and the foliage B is pinched and transported by the transport bodies 7.7.
The falling posture of the root vegetable A becomes constant, and the root vegetable A is carried out from the carrying-out section 16 onto the horizontal transport belt 39.

Then, the root vegetables A sequentially conveyed are transported to the left side by the horizontal transport belt 39, the foliage B is cut by the foliage cutting device 43, and the root vegetables A are transported rearward by the rear transport belt 44. It is stored in the storage device 48 manually (or directly from the rear conveyance belt 44). When the root vegetables A are fully filled in the storage device 48 after continuous processing, the storage device 48 is lowered onto the field by the crane 49.

[0019]

As described above, the present invention has the following advantages. First, since the rotary cutting blade performs shearing of the foliage of the root vegetable and cutting of the multi-film, etc., which were performed by the excavator during the harvesting work, the excavated body is released from the resistance of the foliage of the root vegetable, the multi-film, etc. In addition, the root vegetables can be dug smoothly without being damaged, and the processing of a multi-film or the like after harvesting can be easily performed. Secondly, root foliar by lobes body is induced without leakage carried in carrier, since we are hung and conveyed continuous harvest root vegetable is able to reliably, also minute Since the leaf and the rotary cutting blade are supported by the same support frame, it can be attached to the root cropper with a simple configuration.
