It may be formed by a member, or may be provided on both sides.

A cutting device 31 having a rotary blade is disposed above the lower transfer device 25 and below the pull-out transfer device 24, and a power take-out portion is provided above the tread adjusting pipe 51. By connecting the power take-out part and the cutting device 31 with a flexible wire 43, the rotary blade is driven to rotate. In the present embodiment, a rotary blade is mounted on the cutting device 31, but the present invention is not limited to this, and a driving type cutting blade such as a reciprocating blade may be mounted.
The power take-out unit drives the weeding device 36 via a transmission shaft in a transmission pipe 46.

A multi-discharge device 81 is provided at the rear of the machine so that the multi-film 9 can be discharged backward by the multi-discharge device 81. The te roller 61 is disposed in front of the multi-discharge device 81, and the mulch 9 via the te roller 61 is further discharged by the transport rollers 63 and 64 via the te roller 62. The transport rollers 63 and 64 are driven by a driving force transmission mechanism disposed in a stay 65 that supports the corresponding roller 62 and the transport rollers 63 and 64.

Next, the multi-transport device of the present invention will be described. 3 and 4, the root vegetables 27 are held by the upper belt 24a of the pull-out and transport device 24 and the lower belt 25a of the lower transport device 25 and transported rearward. At a position above and behind the lower belt 25a and below and below the upper belt 24a, a tele roller 61 rotatably supported on the horizontal axis of the body is disposed. The angle between the tangent line and the rear end of the lower belt 25a is configured to be an angle α with respect to the horizontal. Therefore, the multi-film 9 is connected to the lower belt 25.
From the rear end of a, it rises at an angle α with respect to the horizontal, contacts the roller 61, is lifted up, and is conveyed rearward.
However, in this embodiment, the angle α is set to 30 to 90 °. Therefore, the soil for burying root vegetables attached to the multi-film 9 can be shaken off.

A tele roller 62 rotatably supported on a vertical axis is disposed behind one of the left and right sides (the left side in the present embodiment) of the corresponding tele roller 61. The part is conveyed rearward while abutting on the corresponding tele roller 62. By arranging the corresponding tele-roller 62, it is possible to prevent the multi-film 9 from slipping to the side of the tele-roller 61, and to stably transport the multi-film 9.

The transport roller 63 is located behind the tele roller 62 and outside the tele roller 62.
64 are arranged in parallel in the vertical direction. The driving force is transmitted to the transport rollers 63 and 64 by a driving force transmission mechanism built in the stay 65, and the transport rollers 63 and 64 are configured to rotate inward each other. For this reason, by positioning the start end of the multi-film 9 between the transport rollers 63 and 64 and holding the multi-film 9, the multi-film 9 is drawn between the transport rollers 63 and 64 as the vehicle travels.・
The multi-film 9 is discharged to the side of the machine by 64. The discharge direction of the multi-film 9 from the transport rollers 63 and 64 may be set as the groove direction, and the efficiency of discharging the multi-film 9 into the grooves by the transport rollers 63 and 64 may be improved.

The multi-film 9 is lifted together with the root vegetables 27 by the pull-out transport device 24 and the lower transport device 25, and can be turned up by the pull-in action of the transport rollers 63 and 64, and further transported. It is discharged into the groove between the furrows on the side of the fuselage by the discharging action of the rollers 63 and 64. For this reason, at the same time when the root vegetable 27 is excavated and raised, the foliage of the root vegetable 27 is cut off, the multi-film 9 covered with the foliage is discharged into the groove, and the root vegetable 27 is released onto the ridge, and the ridge is removed. The remaining root vegetables 27 can be dried in the sun, which is important for early harvesting, and the outer skin can be hardened. Also, the soil and mud on the root vegetables 27 can be dried and easily removed to improve work efficiency. You can.

Next, the position adjusting mechanism of the cutting device 31 will be described. 5 and 6, the cutting device 31 is configured to be held at the intersection of the guide 71 and the guide 72. The guide 71 has a support hole 71a at the upper end rotatably supported by the body, and the guide 72 has a support hole 72 at the front end rotatably supported by the body. The guides 71 and 72 have long holes 71b and 7 in the longitudinal direction, respectively.
2b is opened so that the support shaft 31a of the cutting device 31 can be inserted and fixed in the long holes 71b and 72b.

Accordingly, by loosening the fixing of the support shaft 31a and rotating the guide 71 and the guide 72,
The position of the cutting device 31 located at the intersection of the guide 71 and the guide 72 can be moved to perform position adjustment, and within this range, the cutting device 31 can be adjusted in the front-back and up-down directions with respect to the body. Since the position of the cutting device 31 can be adjusted, the cutting position of the foliage of the root vegetable 27 can be easily adjusted.

[0023]

As described above, the present invention has the following advantages. That is, as in claim 1, a weeding device for weeding the foliage at the front of the running unit,
In a vegetable harvester equipped with a transport device that rakes and pulls and transports a root vegetable crop and a cutting device that cuts off the foliage of the root vegetable crop being transported, a pair of rollers are disposed in contact with the rear part of the machine, and the rollers are disposed. By driving the multi-films in opposite directions, the multi-film can be inserted and discharged, so that the multi-film can be pulled out and discharged into the groove at the same time as the vegetable harvest, and the multi-film peeling is performed separately. And the labor can be reduced, and the discharge efficiency of the multi-film can be improved. In addition, the multi-discharge device can be configured with a simple configuration, and cost increase can be minimized.

According to a second aspect of the present invention, the pair of rollers are arranged vertically on one of the left and right sides of the rear part of the fuselage.
It is easy to discharge the multi-film to the side, and a guide or the like is not required, and a simple configuration can be achieved.

According to a third aspect of the present invention, at the front of the traveling section,
In a vegetable harvester equipped with a weeding device for weeding the foliage, a transporting device that rakes and pulls up the root crop, and a cutting device that cuts off the foliage of the root crop in the process of transport,
At the top and back of the lower transport device, the multi-film teroller was arranged horizontally in the left and right direction, the teroller was arranged vertically at the rear of one side of the left and right sides of the applicable teroller, and a roller for drawing in and discharging was arranged at the rear. Therefore, the multi-film can be pulled up while being brought to one side with a simple configuration including two terollers, and the drawn multi-film can be easily discharged.

According to a fourth aspect of the present invention, the line connecting the rear end of the lower transport device and the tangent of the rear roller is 30 ° to 90 ° with respect to the horizontal. 30 ° to 90 °, the soil for burying root vegetables can be shaken off, the multi-film can be discharged stably, and the adhesion of soil to the multi-discharge device can be reduced. . That is, if the rising angle of the multi-film is 30 ° or less, the soil is hard to fall, and
With the above, the multi-film is bent at the ascending portion, and the soil attached to the multi-film is peeled off from the multi-film. In addition, when the rising angle of the multi-film is 90 ° or more, the multi-film is overhanged, soil falls on the multi-film and becomes dirty, and by setting it to 90 ° or less, the multi-film is positioned below the soil attached to the multi-film. Without causing the soil attached to the multi-film to fall directly to the ground. The durability of the multi-discharge device can be improved.
