DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-sheet cutting device attached to a root vegetable harvesting machine for harvesting root vegetables such as radish, carrot and burdock.

[0002]

2. Description of the Related Art In cold regions such as Hokkaido, when harvesting root crops, harvesting is performed with multi-sheets laid on the ridges. The catching work was difficult. As a conventional example of the multi-sheet cutting device of the root crop harvester,
JP-A-5-244809 (Japanese Patent Application No. 4-49983)
There is a "root crop harvester". In the conventional example, there is a claim in the claim that "a multi-film cutting tool is provided rearward from the drawing start end of the drawing belt and opposed to the ridge adjacent to the excavating blade." Further, in the column of (0014) of the detailed description of the invention, "A vertical mounting boss 24 is fixed to the outer inclined frame portion 14, and a support 25 is inserted through the mounting boss 24 and the height is increased by bolts or the like. The cutting tool 26 is provided at the lower end of the support 25.
Is provided. There is a description.

[0003]

In the conventional multi-film cutting tool of the root vegetable harvesting machine, the raising and lowering function is not disclosed in the outer inclined frame portion 14 provided with the cutting tool, and furthermore, the adjustment of the cutting tool is not performed. The height of the multi-film cutting tool can be adjusted by bolts and the like by using a mounting boss 24 fixed vertically to the outer inclined frame portion 14 and a support 25 inserted into the mounting boss 24. Each time, the worker loosened the bolts and the like to adjust the height, and the work efficiency was poor.

If the cutting device for the multi-sheet is fixed to the frame, the cutting device fixed there may be damaged by touching the ground surface when moving. Also,
Even if the cutting device is mounted on a vertically movable frame, if the multi-sheet cutting device is fixed to the lifting frame, the height from the ground surface is small, and on uneven terrain, the cutting device will touch the ground surface and break. There was a fear. Furthermore, in the open-field cultivation, a cutting device is not required even at the time of work, and a height as far as possible from the ground surface is required.

[0005] Further, when cutting a multi-sheet, unless a part of the multi-sheet is pressed by a crawler section of a traveling vehicle, the multi-sheet is pulled by a cutting device (cutter section) and cannot be cut well. However, since the ridge width, the number of the ridges, and the interval between the ridges on which the root crops are planted differ depending on the location, it is necessary to change the installation position of the cutting device in the running direction.

Next, the operation of the embodiment of the present invention will be described. The traveling vehicle 10 travels by a worker (driver) B1 of the control unit 11. When performing a harvesting operation in a field, first, the lifting frame 101 is moved to the lifting fulcrum 101a.
The traveling front end is lowered around (FIG. 6). At this time, if the operation lever 205a is rotated in the Y direction to release the interlock, the rotating cutter 203 does not descend even when the elevating frame 101 descends. Conversely, when the operating lever 205a is rotated in the X direction, when the elevating frame 101 descends, it automatically descends in conjunction with the elevating frame 101 to enter a multi-sheet cutting state.
This selection is made depending on whether or not the multi-sheet is used in the field.

The installation position of the rotary cutter 203 is adjusted in accordance with the distance between the ridges of the root vegetables A such as radish in the field.
Adjust in the width direction of 0. This adjustment is performed by rotating cutter 2
03 is attached to the support portion 200 on the left or right side in the width direction (FIGS. 9 and 11), and the spacer 2
06 is selected and attached (FIG. 10), and the position of the cutter unit 203 is adjusted.

The root vegetables A such as radish in one row first raises the foliage AL which is falling forward and backward and left and right by the horizontal projection of the foliage raising device 7 at the tip.

The foliage AL that has been caused is pulled out by holding the relatively upper part of the foliage AL by the pulling portion 1a at the upstream end of the pair of left and right elastic endless belts of the pulling and conveying body 1, and pulls it diagonally backward. Conveyed.
At this time, the soil is vibrated by the soiler device 6 located on the side of the pull-out portion 1a, and the root AR is easily pulled out.

The root crops A, which are nipped at the upper part of the foliage AL and conveyed by the pull-out carrier 1, are further lifted up by the pull-out carrier 2 while nipping the lower part of the foliage AL by the positioning carrier 2. The shoulder at the upper end of the root AR contacts the lower surface of the positioning carrier 2. Therefore, in the root vegetables A to be transported, the vertical position of the foliage AL is determined, and the cutting position of the foliage of all the root vegetables A is the root AR.
It becomes constant from the top.

The root vegetables A are sandwiched by the foliage first sandwiching position 41 of the foliage transporting body 4 located upstream of the foliage detaching position 21 on the downstream side of the positioning transporting body 2.
Without being dropped, the upper part of the foliage AL is held by the foliage transporter 4 as it is, and the lower part of the foliage AL is gripped by the root transporter 3 and transported.

As it is, the root vegetables A are transported downstream,
It is cut by a rotary cutter 5 located between the root carrier 3 and the foliage carrier 4. At this time, the transport speed of the root transport 3 is faster than the transport speed of the foliage transport 4. In this embodiment, the transport speed ratio is about 1.2 times that of the root transporter: foliage transporter = 18/15, the transport speed of the root transporter 3 is 0.689 m / s, and the foliage transporter. 4 is 0.574 m / s). Therefore, the root AR
The foliage AL becomes oblique even in the vertical direction due to its own weight, and the foliage AL is substantially perpendicular to the rotating blade of the rotary cutter 5. For this reason, the cutting angle of the foliage AL becomes perpendicular to the longitudinal direction of the root vegetables, the cut surface of the foliage of several cm remaining in the root AR becomes a plane perpendicular to the longitudinal direction of the root vegetables, and the length of the foliage is substantially uniform. Therefore, the commercial value of root vegetables A is improved.

The cut foliage upper part AL0 is transported from the foliage transporter 4 to the foliage discharge chute 80 by the foliage discharger 8, and discharged to the field.

The root AR of the root crop A, whose upper part of the foliage AL has been cut, is transported to a position above the pedestal 9 by the elastic endless belt of the root transport 3 and hits a roller or a bar 90 to be turned sideways by the worker B2. It is arranged on the cradle 9 and immediately stored in the root vegetable storage container 13 from the cradle 9.

Further, the root AR is stored in the root vegetable storage container 13.
When the vehicle accumulates, the traveling vehicle 10 is stopped, and the operator B1 who gets off the traveling vehicle 10 operates the control unit 126 of the crane unit 12 as a driver. The position of the hook 125 of the crane unit 12 can be freely moved up, down, front, rear, left and right around the pivot column 120.
Is provided close to the center of gravity of the root vegetable harvester, so that even if the root vegetable storage container 13 is full of root vegetables and is heavy, it can be safely placed anywhere around the root vegetable harvester. The root vegetable storage container 13 can be loaded and unloaded.

After completion of the harvesting operation, the lifting frame 101 is raised by rotating the lifting fulcrum 101a. When the operating lever 205a is positioned in the X direction, the cutter unit 203
In the working state, when the elevating frame 101 is rotated up and down, the elevating frame 101 is also rotated with respect to the elevating frame 101 and rises. If the operating lever 205a is located in the Y direction and is in a moving state, the elevating frame 101 moves up while being kept close to the elevating frame 101 (FIG. 7).

[0045]

According to the present invention, the multi-sheet cutting device automatically moves in the direction of the elevating frame when the elevating frame is moved up and down to be in a moving state, and is automatically interlocked with the elevating frame when the elevating frame is lowered. It turns and descends to the working state. For this reason, when the traveling vehicle travels, the cutter unit can be ascended and the forgetting of the elevation due to carelessness can be prevented. Therefore, there is no possibility that the cutter portion is damaged due to irregular terrain or the like.

The lifting of the lifting frame and the raising and lowering of the cutter unit (rotary cutter) are released by the operation rod, so that the lowering frame does not fall even if it is lowered, and the cutter unit (rotary cutter) is operated by the operator. It can be lowered to the working state. For this reason, in a field or the like where multi-sheet cutting is not necessary, even if the elevating frame is lowered at the time of work, the harvesting work can be performed by separating from the ground surface without lowering the cutter portion.

When cutting the multi-sheet, it is necessary to press a part of the multi-sheet by the crawler portion of the traveling vehicle. The ridge width, the number of rows, and the interval between the rows vary depending on the field of root vegetables. Since the cutter section of the apparatus can be moved and installed in the width direction of the traveling vehicle, the multi-sheet can be cut at an appropriate position and the end of the multi-sheet width is left with an appropriate width.
