A cutter 47 is arranged between 46 and the horizontal conveyor 45. The root portion of the root vegetable transported by the auxiliary transport conveyor 36 is taken over by the horizontal conveyor 45 and transported rearward while the upper end of the root portion of the root vegetable is positioned, and the leaf portion is cut by a cutter 47 at a predetermined position. Shock absorbing plate 7 made of an elastic body disposed underneath
0, and then slides down onto a lower conveyor 48 disposed below the shock absorbing plate 70, and the leaves are transported to the leaf discharge conveyor 44 and dropped into the field scene from behind. .

The lower conveyor 48 is composed of a wide belt conveyor, and is disposed horizontally from the rear lower part of the auxiliary conveyor 36 to the rear.
A lateral feed roller 49, which will be described later,
Are arranged. By the rotation of the lateral feed roller 49 and the conveyance drive of the lower conveyor 48, the root vegetables fall on the sorting conveyor 50 at the side. The sorting conveyor 50 comprises a wide roller conveyor arranged at the rear of the machine in the left-right direction so as to remove soil adhering to root vegetables while being fed to the side. A container mounting table 54 is arranged below the end of the sorting conveyor 50, and the container mounting table 54 has the container 9 mounted thereon.

A shoulder alignment guide 51 and a tail cutting device 61 for cutting the root of the root vegetable are provided below the front end of the pulling conveyor 30 of the self-propelled root vegetable harvester.

Is arranged. By the guide guard 62, the roots of the root vegetables which are conveyed while the leaves are held by the pull-out conveyor 30 are guided by the disk cutters 13 and cut. In addition, below the cutting portion 63, a box body having an open upper surface is placed. The box is adapted to receive root vegetables that have failed to be pinched due to irregular cultivation, very small root vegetables, and the like.

Next, the lateral feed roller 49 will be described. As shown in FIGS. 3 and 4, a lower gear box 52 is disposed on the left side of the lower conveyor 48, and a transmission shaft 53 is horizontally mounted on the lower gear box 52 and a transmission shaft 55 is provided.
Are vertically supported, and the power transmission shaft 53 and the power transmission shaft 55 are configured to transmit power via bevel gears. An upper gear box 51 is supported on the lower gear box 52 so as to be rotatable left and right about the transmission shaft 55.
One end of the drive shaft 49a is rotatably supported, and a bevel gear is fixed to an end of the drive shaft 49a and an upper end of the transmission shaft 55 to transmit power.

The other end of the drive shaft 49a of the lateral feed roller 49 is rotatably supported by a support plate 70. The support plate 70 is in a state of being obliquely lower in FIG. 3 and a storage state shown by a two-dot chain line. , And is fixed to the main body with bolts and pins. However, it is also possible to connect the piston rod of the cylinder to the support plate 70 so that the position can be changed between the hand-licking position and the storage position or an intermediate position by a switch operation or the like.

In such a configuration, power is transmitted from the output shaft of the engine to the transmission shaft 53 via a clutch, a pulley, a belt, and the like. The transmission shaft 53 transmits the power to the transmission shaft 55 via a bevel gear, and further transmits the power to the drive shaft 49a via the bevel gear, thereby rotating the lateral feed roller 49. The rotation of the horizontal feed roller 49 and the conveyance drive of the lower conveyor 48 cause the root vegetables to drop onto the side sorting conveyor 50.

When harvesting winter ginseng with short and firm foliage, the foliage may be conveyed without being cut or with foliage remaining. There is a possibility that the sheet is caught, and if it is caught, it cannot be dropped and conveyed to the sorting conveyor 50, so that clogging occurs. In order to prevent such a problem from occurring, according to the present invention, as shown in FIG. 3, the horizontal feed roller 49 is rotated to the left around the transmission shaft 55 so as to be in a position parallel to the traveling direction. By doing so, the winter ginseng transported by the lower conveyor 48 is discharged to the rear of the fuselage without dropping on the sorting conveyor 50, and the ginseng is harvested by arranging the container at this discharge position.

When the winter ginseng is harvested in this manner, the cutting operation of the remaining foliage is performed manually, but since the lateral feed roller 49 is not used, the cutting operation is not interrupted and the harvesting operation is not interrupted. In other words, it is only work to excavate winter ginseng by the root vegetable harvester, but it is heavy labor to perform the excavation work manually, so rather than clogging with the diagonal roller 49 and harvesting manually without using the root vegetable harvester The effect of reducing the work is great.

As shown in FIG. 5, the rear end of the sorting conveyor 50 can be disposed rearward of the end of the traverse roller 49, and the rotation of the traverse roller 49 and the lower conveyor 48 can be arranged. The root vegetables conveyed by the conveyance drive of the above can be conveyed using the full width 50a of the sorting conveyor 50 on the side. That is, as shown in FIG. 2, when the rear end of the sorting conveyor 50 and the rear end of the lower conveyor 48 are positioned substantially on the same line, when the ginseng is conveyed by the lateral feed roller 49, the rear end of the sorting conveyor 50 collects. They will be transported, making it difficult to sort. Therefore, by arranging the rear end side of the sorting conveyor 50 behind the end side of the traverse roller 49, the sorting conveyor 50 can be conveyed using the entire width of the sorting conveyor 50, and there is little damage due to interference between the root vegetables. At the same time, the damaged product can be easily found, and the manual sorting operation becomes easy. Also,
Work speed is improved.

If the upper surface of the lower conveyor 48 and the upper surface of the starting end of the sorting conveyor 50 are made to coincide with each other as in the prior art, a depression is formed between the right side surface of the lower conveyor 48 and the upper surface of the roller of the starting end of the sorting conveyor 50. When a root-shaped space is formed in the hollow and the root crop falls, it is no longer transported. Therefore, as shown in FIG. 8, the left end portion of the sorting conveyor 50 is arranged below the lower conveyor 48 in rear view, and the sorting conveyor 50 is configured to be inclined to the left side, so that the sorting conveyor 50 is sorted from the lower conveyor 48. It is possible to prevent root vegetables from being clogged between the conveyors 50, and there is no stagnation due to clogging, etc., even for the very small root vegetables, so that the flow of the root vegetables is constant, and the manual sorting operation can be easily performed.

As shown in FIG. 9, the sorting conveyor 50 is provided with elastic projections 83 made of resin or the like, and the roots are forcibly conveyed by the projections 83. It can be configured as follows. Therefore, stagnation or clogging of root vegetables does not occur, and a constant transport speed can be maintained. Also, the protrusions 83
It is made of an elastic material such as resin and does not damage the harvested root vegetables.

The projections 83 of the sorting conveyor 50
83 can be made into a comb-like elastic body in plan view as shown in FIG.
When inserting and placing 8 to transport root vegetables with soil,
The soil can be removed from the gap between the comb-like elastic body and the sink plate 58, and the soil does not stagnate and adhere.

[0028]

As described above, the present invention has the following advantages. That is, the front end side of the lateral feed roller is rotatably supported on the horizontal plane, and the rear end side can be fixed to the storage position parallel to the oblique position and the traveling direction,
When the root stem of the leaf is conveyed to the lower conveyor while remaining, the horizontal feed roller can be made parallel to the traveling direction and not used as a storage position, but harvested at the rear of the machine, The root vegetables are not clogged by the lateral feed rollers, and the operation can be performed continuously. In addition, when the leaf stems are reliably cut, the lateral feed rollers can be arranged obliquely and sent to the sorting conveyor, and the transport direction can be arbitrarily changed depending on the type of root vegetables.
