ようになっている。(Prior art) Various configurations have been proposed for harvesting machines for harvesting root vegetables such as radishes, but most of these machines generally have a digging structure at the lower front of the main body frame. At the same time, a conveyor is connected to the rear of this digging body, and the root vegetables are dug up in the front part in the direction of movement by the digging body, and the root vegetables are carried to the conveyor, and the conveyor is connected to the rear of the digging body. A conveyor transports root vegetables to the rear in the direction of travel.
(発明が解決しようとする課題)
上記の収穫機によると、掘取られた根菜類は、進行方向
の後方部に、すなわち、根菜類の掘取り後の畝上に放出
されるため、根菜類を掘取った一工程毎にその根菜類を
側方部に排除するか、または拾い上げる作業を行なわな
ければ次の列の根菜類を掘上げ収穫することができず、
したがって、各列の根菜類を連続的に掘上げ収穫するこ
とができず、作業能率上好ましくないという問題がある
。(Problem to be Solved by the Invention) According to the above-mentioned harvesting machine, the dug up root vegetables are discharged to the rear in the direction of travel, that is, on the ridge after the root vegetables have been dug up. The next row of root vegetables cannot be dug up and harvested unless the root vegetables are removed to the side or picked up after each step of digging.
Therefore, there is a problem in that root vegetables in each row cannot be continuously dug up and harvested, which is unfavorable in terms of work efficiency.
本発明はこのような点に鑑みなされたもので、根菜類を

A carry-in part that is connected to the rear part of the main body frame and carries in the dug up root vegetables is located close to the rear part of the digging body, and a carry-out part for the root vegetables is arranged on the other side opposite to the carry-in part. The transport conveyor is provided on the main body frame side so that the overall width dimension in the traveling direction can be varied by rotation.
(作用)
本発明の根菜類収穫機では、本機の本体フレムを、たと
えば、トラクタの三点リンク機構に連結するとともに、
本体フレームの一側部の掘起体を収穫する根菜類の列の
畝に臨ませる。(Function) In the root vegetable harvesting machine of the present invention, the main body frame of the machine is connected to, for example, a three-point linkage mechanism of a tractor, and
The excavated body on one side of the main frame faces the ridges of the rows of root vegetables to be harvested.
つぎに、トラクタにより本機を牽引進行すると、掘起体
により畝の根菜類が順次細土げられるとともに、この根
菜類が搬送コンベヤの搬入部に順次搬入される。Next, when the machine is towed by a tractor, the root vegetables in the ridges are successively ground up by the excavator, and the root vegetables are successively carried into the loading section of the conveyor.
そして、各根菜類は進行方向−側部の搬入部から進行方
向他側部に向って順次搬送されるとともに、この他側部

ことができる。Then, each root vegetable is sequentially transported from the carry-in section on the side in the direction of travel toward the other side in the direction of travel, and from the carry-out section on the other side to the side in the direction of travel after digging up the root vegetables. That is, they are sequentially carried out to the opposite side of the excavation body. Therefore, since space for the machine to move is secured, root vegetables in multiple rows of ridges can be continuously dug up and harvested by moving the machine back and forth.
また、非作業状態での移動、運搬または収納保管時には

搬出される。Further, the upper part or the base of the stems and leaves of the radish A carried into the carrying-in part 58 is held between the inner running parts of the pair of endless running bodies 4, and is transferred from the carrying-in part 48 on one side of the guide path 37. The radish A is transported while being suspended upward in order toward the carry-out section 49 on the other side in the direction of travel, and the radish A is transported from the carry-out section 49 on the other side to the left side in the direction of progress after being dug up. That is, they are sequentially carried out to the side part on the opposite side from the excavation body 21 on the right side part. In this case, by the large number of clamping pieces provided on the outer side of the pair of endless rotating bodies 46, the clamping pieces are sequentially moved while facing each other in the inner rotating part, so that the radish is placed between the opposing clamping pieces. The upper part of the radish A or the base of the stems and leaves, etc., are automatically clamped, and the radish A is gradually carried and carried out from the carrying-out section 49 while being gradually suspended upward.

落下することがない。At this time, the pair of endless rotating bodies 46 includes a plurality of guide bodies 50 and tension rollers 5! on the inner and outer sides. Since a predetermined position of the radish A is sandwiched between the inner rotating parts, the pair of endless rotating bodies 46 are further tensioned, and therefore the radish A falls during transportation.

The radishes A, which are successively thinly soiled at the right end of the side, are sequentially carried out and dropped to the left end of the other side in the direction of travel. Therefore, since space for the machine to move is secured, by moving the machine back and forth, root vegetables in multiple rows of ridges can be continuously dug up and harvested.

菜類を確実に浮上させるようにあらかじめ設定する。The vertical movement of the grounding ring 24 is adjusted depending on the type of root vegetables such as radish A and their growth degree, and settings are made in advance so that root vegetables of various sizes can be reliably floated.

槙のように小さくなる。In addition, when moving, transporting, or storing in a non-working state, the connecting shaft 58 connecting the connecting portion 56 of the connecting arm 28 and the front end of the arm 57 is pulled out, and the arm 5
7 is connected to a connecting portion 55 at the rear end of the connecting arm 28 by a connecting shaft 58. Along with this, the entire transport conveyor 31 is connected to the connecting arm 27 on the negative side and the connecting part 33 on the one side.
The conveyor 31 rotates around the support shaft 54 connected to the main shaft 54 as a fulcrum, and the conveyor 31 rotates from the state shown by the solid line in FIG. 1 to the state shown by the chain line in FIG. It becomes small like a pine tree.

ことができる。If the width of the transport conveyor 31 protrudes from the width of the main body frame 1 in the working state, moving or transporting in this state tends to cause the protrusion to get in the way, which is also unfavorable from a safety point of view. However, as described above, by rotating the transport conveyor 31 to reduce the overall width in the direction of movement, safety during movement and transportation can be improved, and the space required for storage can be reduced. Can be done.
