Abstract

PURPOSE:To provide the transfer device capable of always cutting the leaf parts of root vegetables at a prescribed position by directing the root vegetables in the lower direction during their carriage, sliding and transferring the directed root vegetables, and subsequently stopping the root vegetables at a prescribed position. CONSTITUTION:Root vegetables are nipped and transferred between pulling endless members 8, 8 in hung postures, successively changed into approximately horizontal postures through a direction-controlling plate at the terminal position of the endless members, and subsequently dropped and supplied on a transfer belt 9. While transferred with the transfer belt 9, the root vegetables are downward directed, slid, transferred and subsequently stopped with a stopper 23 at a prescribed position, where the leaf parts of the root vegetables are then cut with a cutter blade 24.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device such as a root crop harvester for picking up root crops to be cultivated along a soil surface formed on a ridge while holding and transferring the crops and further cutting the leaves. It can be used for picking and harvesting radish and turnip.

[0002]

PRIOR ART AND PROBLEM TO BE SOLVED BY THE INVENTION A root crop is planted in a ridge, for example, by running along a ridge of a root vegetable crop, for example, the ridge of a radish. The radish is picked up from the ridges and transferred during the transportation of the radish to the rear upper part, and the leaves of this radish are cut by a cutting blade in the vicinity of the end, and the cut radish is removed from the end. It is dropped and supplied to the lower transfer device, transferred by this transfer device, and supplied and stored in the storage tank.

In the above-mentioned radish leaf cutting operation, the radish is held between the drawn endless bodies, and the radish is cut while the radish is being transferred in a suspended posture, whereby the radish is transferred. It may slide down inside, so that certain positions may not be cut, and it is necessary to perform aligning work again in the post process, which resulted in poor work efficiency, but it was eliminated and labor saving was done. It is something to try.

[0004]

According to the present invention, the root of the root vegetable (a) is held between a pair of left and right drawn endless bodies 8 and is transferred to the upper rear portion while the root vegetable (a) is removed from the field. The withdrawal endless body 8, which is provided so that the root part of the root vegetable (a) is transferred from the hanging end position to the horizontal position while being sequentially dropped by the direction regulating plate 19 provided near the end part, A groove 22 having a mountain shape is formed in the lateral direction with respect to the transfer direction in which the falling root vegetable (a) is received and is transferred to the lower side of the terminal end of 8 and one end side is inclined downward and the lower end edge is inclined. Is rotatably provided with a transfer belt 9 provided with a stopper 23 for receiving the neck portion of the root vegetable (a).
A cutting blade 24 for cutting the leaf portion is provided on one side of the end portion, and a storage tank 10 for storing the root vegetable (a) whose leaf portion has been cut is provided on the rear side of the transfer belt 9. The configuration of the transfer device of the root crop harvester.

[0005]

[Operation and effect of the invention] By running the root vegetable harvester along this ridge of the radish (a) of the root vegetable crop planted in the ridge, the leaves between the pair of left and right withdrawn endless bodies 8, The radish (a) is removed from the ridges and is transferred while being held and transferred toward the upper rear part, and the direction regulating plate 19 at the terminal end is transferred.
Is transferred while sequentially changing the root portion of the hanging posture to a substantially horizontal posture, and the transfer belt 9 from the end portion to the lower side.
The radish (a) is dropped and supplied upward in a horizontal posture, and the radish (a) enters the groove portion 22 while being transferred by the transfer belt 9, and one end side of the transfer belt 9 is inclined downward, When it is slid toward, the stopper 23 stops the neck portion of the radish (a) and it is transferred to the vicinity of the end of the transfer belt 9, the radish (a) is moved.
The leaf portion is cut by the cutting blade 24, and the cut radish (a) is supplied from the terminal end portion into the storage tank 10 and stored therein.

As described above, the radish (a) which is being transferred in the suspended posture by the withdrawal endless bodies 8 and 8 is sequentially changed to the substantially horizontal posture by the direction regulating plate 19 and is supplied onto the transfer belt 9. 9 Sliding the upper part to the lower part, stopper 2
At 3, the neck of this radish (a) is stopped and the leaf is cut, so that a fixed position is always cut,
For this reason, it is not necessary to perform the trimming again, the work efficiency can be greatly improved, and the work can be saved.
