Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for digging root crops such as onions from a field.

[0002]

2. Description of the Related Art Conventionally, in a self-propelled vehicle, a digging device for excavating and excavating the underground part of a field, a transfer device for picking up and transporting root crops, and a cutting of foliage from a root crop in transit. There has been a harvester equipped with a working unit including a cutting device for separating and a discharging device for discharging a root vegetable crop after separating the foliage from the machine body.

[0003]

Usually, onions are cut off and the stems and leaves are cut and cut to a length of about 15 mm before shipment. However, this finishing work cannot be performed by conventional harvesters, and it can be done manually or after harvesting. The first object of the present invention is to provide a harvester capable of harvesting root vegetable crops in a finished state for shipment.

Further, since the above harvesting machine is operated at the rear part of the machine body, it is difficult to see the root vegetable crop just before harvesting at the lower front part of the machine body, and the steering operation is mostly carried out depending on the feeling of the operator. A second object of the present invention is to provide a harvester that can notify the operator immediately when the traveling position deviates from the proper traveling position and can travel while always maintaining the proper position.

[0005]

The harvesting machine of the present invention for achieving the above first object is a harvesting machine having a working unit for harvesting root crops in a self-propelled vehicle. The foliage cutting device for cutting and the root cutting device for cutting the root part are provided in the working section.

The root cutting device is preferably attached to the elastic body so as to move up and down according to the size of the root crop.

The harvesting machine of the present invention for achieving the above second object is a harvesting machine having a working unit for harvesting root crops in a self-propelled vehicle, wherein work for root crops at a substantially central position between planting rows is performed. A steering sensor for detecting the positional deviation of the center of the section is provided at the front of the working section, and an indicator for displaying the direction of the positional deviation is provided at the rear of the vehicle.

The lower end of the traveling locus of the tip of the tine (17) of 8) is formed to extend to the slope to prevent a gap from being formed between the left tine (17) and the slope, and the left bushing raising case (18 The tine (17) of (1) is surely acted on the foliage portion (16a) to prevent the onion (16) from being left unetched due to poor raising of the foliage portion (16a).

Further, the root arm mounting bracket (79) of the left weed raising case (18) is divided into an upper fixed side and a lower movable side, and the upper fixed side mounting bracket (79a) is attached to the left weed supporting frame ( 82) by bolting, the left fixed grass raising case (18) is fixed and supported by the upper fixed side mounting bracket (79a), and the lower movable side mounting bracket (79b) is turned to the upper fixed side mounting bracket (79a). The lower movable side mounting bracket (79b) is movably connected to the root arm (19) and the weed plate (76).
And the height of the root side arm (19) and the tip side of the grass plate (76) are adjusted by adjusting the rotation of the lower movable side mounting bracket (79a).

Further, a weeding board (7) for inheriting the foliage (16a) to the tines (17) of the left weeding raising case (18)
6) The end portions of the guide surfaces (76a) (77a) of (77) are extended rearward (inner side) from the traveling locus of the tip of the tine (17) in a side view, and the vegetation plates (76) (77) are used. The tine (17) causes the fallen foliage part (16a) to be raised immediately after scooping.

Further, the upper part of the right sward raising case (18) is attached to a mounting bracket (98) extending from the sprocket drive case (97) in which the sprocket shaft (44) is housed, around the sprocket shaft (44) axis. Rotatably adjustable, the root arm mounting bracket (79) of the right sward raising case (18) is divided into an upper fixed side and a lower movable side, and bolted to the right sward supporting frame (82). A lower movable side mounting bracket (79b) for fixing the lower part of the right bushing raising case (18) and the root arm (19) is fixed to an upper fixed side mounting bracket (79a) for fixing around the sprocket shaft (44) axis center. The right sward raising case (18) is rotatably and rotatably connected, and the right sward raising case (18) is fixedly supported rotatably back and forth around the axis of the sprocket shaft (44). 14) If the action in terms, central split grass caused case (18) and fixedly supported on the forward rotational position to be parallel right tine (17) the tip of the rotating line trajectory lower the ridge (14)
On the other hand, when the right sward raising case (18) is made to act on the slope on the right side of the ridge (14) while being aligned with the upper surface, the right tine (18) is fixed at a rearward rotation position behind the central sward raising case (18). 17) The lower end of the circular trajectory of the tip is configured to extend to the slope as in the case of the left sward raising case (18).

As shown in FIG. 33, the weeding board (76) is provided separately from the rooting arm (19), and the tip of this weeding board (76) is rocked back and forth to the tip of the rooting arm (19). Dynamic fulcrum axis (9
9) is attached so that it can swing back and forth, and the rear part of the weeding plate (76) is interlockingly connected to the left vibration blade (23) via the rod (100), so that the vibration blade (23) can be rocked back and forth. , The guide surface (76a) of the vegetation plate (76) for allowing the tine (17) of the left sward raising case (18) to inherit the foliage portion (16a), and the feed end portion of the tine (17) is rotated in a side view. It is reciprocated between the forward position and the backward position from the line locus to prevent the foliage part (16a) from staying on the sward plate (76), and at the same time from the sward plate (76) to the tine (17). It is configured to improve the inherited state of (16a).

The vegetation board (77) for early life is replaced with the vegetation board (7).
6), it is possible to detachably attach the vegetation board (77) for early life and swing it back and forth integrally with the vegetation board (76). In this case, the front side vegetation board (77) is reciprocally moved back and forth with the turning locus of the tip of the tine (17) as a boundary.

As is apparent from the above examples, the present invention provides a self-propelled vehicle (1) having a working unit (2) for harvesting a root crop (16), which is used to produce a root crop (16). A foliage cutting device (25) for cutting the foliage part (16a) and a root cutting device (51) for cutting the root part (16d) are provided in the working part (2). It has the effect of being able to harvest in the finished state and simplifying post-treatment after harvesting.

Even if the size of the root crop (16) changes, the root cutting device (51) is attached to the elastic body (55) so as to move up and down according to the size of the root crop (16). The present invention has an effect that the root (16d) can always be properly cut without having the root (16d) cut too much or left uncut.

Further, in the harvester equipped with the working unit (2) for harvesting the root vegetable crop (16) on the self-propelled vehicle (1), the working unit (2) for the root center of the root vegetable crop (16) approximately at the center position.
Steering sensors (88) (89) for detecting center misalignment
Is provided at the front of the working unit (2), and indicators (90) and (91) for displaying the direction of displacement are provided at the rear of the self-propelled vehicle (1) to prevent the aircraft from shifting from the proper traveling position. It is possible to perform proper harvesting work without leaving behind.
