Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically removing roots of root vegetables arranged in a root vegetable harvesting machine for continuously extracting and harvesting root vegetables.

[0002]

2. Description of the Related Art Conventionally, a self-propelled or tractor-pulled root vegetable harvesting machine is provided with a digging device on the upper side of the carrier body, and the extracted root vegetable carrier is carried by the carrier body by sandwiching the leaf portion. However, a structure in which an operator or the like stores the harvested root vegetables in a storage container from the lower side of the carrier is known,
Some of these are provided with a leaf portion removing device for automatically removing the leaf portion of the root vegetables to be conveyed.

[0003]

However, a bottom root of a root vegetable such as a radish, for example, extends long, and this bottom root must be removed before shipping. In the conventional root vegetable harvester, the worker controls the posture of the root vegetable by facing the cutting device of the leaf portion, but since the cross-sectional area of the leaf portion is large, it is easy to control the posture. Even if a cutting device is provided, it is very thin, and the position of the hairline is not constant. It is difficult to align the postures of the buttocks evenly to the cutting position, so the buttocks are automatically removed. The device is not in the conventional root crop harvester,
Since the worker boarded the root vegetable harvester and manually removed the roots from each root vegetable, the work efficiency was poor.

[0004]

The present invention uses the following means in order to solve the above problems. That is, the root vegetables are continuously pulled out, the leaves are sandwiched by the carrier, and in the root vegetable harvester that conveys the root vegetables in a suspended state, a guide plate for guiding the lower end of the root vegetables is provided in the middle of the lower part of the carrier, A cutting device is provided below the end of the guide plate in the vicinity of the lower side of the conveyance, and a successor member for guiding the lower end portion of the root vegetable to the cutting device is provided from the end of the guide plate. The cutting blade of the cutting device has a V-shape as viewed from above, and the cutting blade of the cutting device is arranged in an inclined position with the lower side of the conveyance downward, and further the guide plate and the cutting device are attached to the conveyance body of the root vegetable harvester so as to be vertically adjustable. It is the one that constitutes the butt root removing device.

[0005]

[Operation] The lower end of the root vegetables conveyed in a suspended state on the carrier comes into contact with the guide plate, the leaves of the root vegetables are sandwiched by the carrier and pulled, and the lower end is dragged on the guide plate. ,
The root vegetables are conveyed in an inclined posture, and when the bottom part of the bottom of the bottom of the guide plate is removed from the end of the guide plate, the bottom end of the root plate, which is dragged on the guide plate by the weight of the root vegetables, is conveyed. Rotate vertically downward with the leaf sandwiching portion as a fulcrum. Since the cutting device is located in the middle of the rotation direction, the bottom root extending from the lower end of the root vegetable is cut by the cutting device as the root vegetable rotates.

Further, by making the shape of the guide plate curved downward in a rear view, the lower end of the root vegetable is surely guided to the end of the guide plate, and the inheritance member is arranged in the cutting device from the end of the guide plate. This ensures that the root root of the root vegetable is inherited by the cutting device, and the cutting direction of the cutting device is the tilting direction with the conveyance lower side, that is, the leaf pinching part side of the root vegetable downward, and the rotation of the lower end of the root vegetable. Since the direction is the same, the buttocks root is surely cut.

Further, for example, when the root vegetables are short and the vertical rotation amount of the lower end portion of the root vegetables from the end of the guide plate to the cutting device is small and cannot reach the cutting device, the guide plate and the cutting device are displaced upward. The vertical rotation amount of the lower end portion of the root vegetable is increased, and the cutting device is also positioned above, so that the hairline portion of the root of the root can reliably pass through the cutting position of the cutting device and be cut. That is, since the upper and lower positions of the guide plate and the cutting device can be adjusted, the tail root cutting can be reliably performed according to the length of the root vegetables.

[0018]

Since the present invention is configured as described above, it has the following effects. That is, since the root root harvesting device is provided with the root root removing device as in claim 1, the root portion is clamped and conveyed so that the lower end portion of the root vegetable to be conveyed comes into contact with the guide plate and is dragged to the end of the guide plate. When it is disengaged from the portion, the lower end portion is rotated downward by its own weight, and the hip root is naturally conveyed to the cutting position of the cutting device to be cut. That is, since the roots are automatically removed during the transportation of root vegetables, it is not necessary for the worker to cut the roots of individual root vegetables as in the conventional case, which contributes to a great improvement in work efficiency.

Further, since the inheritance member for guiding the tail root portion to the cutting position of the cutting device is arranged at the terminal end portion of the guide plate as in claim 2, there is no positional deviation and the tail root is reliably conveyed to the cutting position. Further, according to claim 3, since the guide plate shape is curved downward in the rear view, the lower end portion of the root vegetable is guided to the curved bottom portion of the guide plate, and the lower end portion of the root vegetable is reliably placed at the cutting position. Can be transported.

Further, since the cutting direction of the cutting device is set as in the fourth aspect, the root locus coincides with the rotation locus of the root root when the root vegetable is disengaged from the end of the guide plate and pivots downward. Not only does it cut smoothly, but the cut is straight in the left-right direction of the root vegetable, and it can be shipped without the need to process the cut of the root after that.

Since the vertical height of the mounting position of the guide plate and the cutting device to the root vegetable harvester can be adjusted as in claim 5, the guide plate is moved upward when the root vegetable is short, for example. Then, even for a short root vegetable, the lower end portion thereof can be guided by the guide plate, and the cutting device also moves upward, so that the cutting position becomes an appropriate cutting position and good cutting of the root root is possible. Even if the root vegetables are long, the attachment position can be moved downward, and similarly good root cutting can be performed.
