Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walk-control type root crop harvester for digging onions, carrots and other root crops from a field and binding them.

[0002]

2. Description of the Related Art A root-operated root vegetable in which a root vegetable crop cultivated in a field is dug up and transferred, the root vegetable crop is bound in the transfer process, and the leaf stems are cut off after the binding. There are known harvesters (for example, Japanese Patent Laid-Open No. Sho 6).
No. 1-81715). Then, a conventional root vegetable harvester holds an upper part of a leaf stem portion of a dug root vegetable crop by a single holding and transferring device, and transfers the transferred product vertically through a shaft of a traveling wheel. The knitting and bundling is performed by a bundling device which is arranged near the one side in the lateral direction of the machine body in front of the line, and the tip of the stem of the root vegetable crop after bundling is cut with a rotary blade.

[0003]

In the conventional root vegetable harvester, only one part of the leaf stem is held and the heavy root is suspended from the holding part and the root crop is transferred in a suspended state. Therefore, the leaf stem is likely to be cut at the holding part and the root part may fall out, or the posture may be disturbed until it does not fall out, especially when the root part is in a drooping state when being fed into the binding device or at the time of binding. However, there is a problem in that the tendency of the posture to be disturbed is particularly severe because of the sliding resistance applied to the above, and good binding cannot be expected.

Further, since the binding device is provided near the one side portion in the lateral direction of the machine body in front of the vertical line passing through the axis of the traveling wheel, the front-rear and left-right balance of the entire harvester is unbalanced. There is a problem that it is not easy to drive while keeping a balance and walking, and furthermore, after the root vegetable crops are knitted and tied, the leaf stems are cut with a rotary blade, so that the root vegetable crops (harvested goods) after binding are made. There is also a problem that cutting resistance is applied to damage the harvested product, or the bundling condition of the harvested product is deteriorated.

[0005]

The present invention was carried out for the purpose of solving the above-mentioned problems, and in order to achieve the object, a root vegetable harvesting machine is provided with the following technical means. . That is, the root vegetable harvester in the present invention,
A weeding device (2) for adjusting the foliage part (1a) of a root crop
And a scraping device (3) arranged at the rear part of the weeding device (2)
And a chisel (4) that digs into the underground part (1b) of root crops,
A foliage-holding transfer device (5) installed by connecting the transfer start end to the scraping device (3), a neck-holding transfer device (6) disposed below it, and a transfer-end of the neck-holding transfer device (6) A bundling device (8) for connecting the bundling passages (7) to each other, and a bundling device
(8) Transfer Cutting device for cutting off the foliage part installed on the good side
(9) The harvesting work section (A) including
(10) In the root vegetable harvesting machine configured to be installed in a walking-controlled self-propelled vehicle (B) having (10), the binding device (8)
Is located below the bundling transmission case (11) and has a focusing passage in the front-back direction.
(7) is located, and the converging passage (7) is sandwiched between the nodules to the left and right.
Configure so that (12) and the needle (13) are located,
The binding device (8) is arranged so that the center of gravity of the binding device (8) is located near the vertical line (Y) passing through the axis of the traveling wheels (10) (10) or behind the vertical line (Y). To do.

Further, in the above-mentioned root vegetable harvester,
The cutting device (9) for cutting off the foliage, which is installed on the transfer side of the binding device (8), is constituted by a vibrating blade that vibrates in the front-back direction, and the vibrating blade is a chisel (4) (4). It is configured to vibrate in the front-back direction by using a driving device (14) for driving the.

[0007]

In the root vegetable harvester according to the present invention, the foliage portion (1a) of the root vegetable crop to be planted is sorted by the weeding device (2), and the root portion (1b) is dug up by the chisel (4). Then, the foliage-holding transfer device (5) and the neck-holding transfer device (6) are held and transferred at two upper and lower positions, and the foliage part (1a) is excised by a vibrating blade under the held state. And
Root crops from which the foliage (1a) has been cut off are bundled in the transmission case.
The nodules (12) located on both sides of the focusing passage (7) are fed into the focusing passage (7) formed on the lower side of the (11) to be focused.
And the needle (13) is actuated to bind.

[0008]

EFFECTS OF THE INVENTION In the root vegetable harvester according to the present invention, since the root vegetable crop in the trimmed state is reliably grasped and transferred, the root vegetable crop does not fall off or the posture is disturbed during the transfer, Further, the cutting process of the foliage is also performed accurately and accurately under a reliable grasping state, and the root vegetable crop after cutting the foliage is sent to the focusing passage on the lower side of the binding transmission case and is focused. It can be sent to the bundling device with a low lifting height, the movement resistance of root crops is also reduced, and the disordering of the bundling posture is less likely to occur, and good bundling is performed.

Since the above-mentioned binding device is arranged near the vertical line passing through the axis of the traveling wheel or behind the vertical line, it is a root crop harvester constructed in a walking control type. However, the front and rear and left and right balance of the harvester as a whole is good, and it is easy to operate while following the walk, and it is also easy to send out the bound product from the binding device smoothly. It is easy to see the work status. The vibrating blade described above configured to be commonly driven by a chisel driving device also has an advantage of simplifying the driving system.
