Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention, when extracting agricultural products such as root vegetables from the field and harvesting them, and transporting them to the rear of the machine, aligns the foliage and the root in order, and the root is determined from the foliage. The present invention relates to a self-propelled agricultural product harvester that cuts at a position.

[0002]

2. Description of the Related Art Conventionally, the foliage of agricultural products vegetated in the field is clamped by a pair of left and right endless bands on a traveling machine, and the root is pulled out from the field to harvest, and the harvested agricultural products are placed behind the machine. Equipped with a harvesting / transporting zone for lifting and transporting, a cutting device is provided below the rear part of the transporting route of this harvesting / transporting zone, which cuts the roots from the foliage of agricultural products at a predetermined position. Immediately before the above, the applicant of the present invention has proposed a harvester provided with a pair of left and right guide bodies whose passages can be freely expanded and contracted according to the size and shape of agricultural products.

Further, the harvesting / conveying belt is provided with a first conveying belt having a length extending from a substantially front end portion to a rear end portion of the machine body, and from a substantially middle position in a longitudinal direction of the first conveying belt to a terminal end portion. And a second conveyor belt that is provided so as to be stacked below the first conveyor belt,
A harvesting machine is also provided in which a cutting device is provided below the second conveyor belt, and a pair of left and right guide bodies whose path is expandable / contractible is provided in front of the cutting device in accordance with the size and shape of the agricultural product. Proposed by the applicant.

[0004]

A harvesting / conveying zone is provided for pulling and harvesting and transporting the harvested agricultural products while hoisting them toward the rear of the machine.
In the harvesting machine provided with a cutting device for cutting the roots of the produce from the leaves at a predetermined position below the rear of the transportation route of the harvesting / transporting zone, the harvesting / transporting zone is approximately from the front end to the rear end of the machine body. A first conveyor belt having a length to reach a portion, and a first conveyor belt provided so as to be superposed on a lower side of the first conveyor belt from a substantially middle position in a longitudinal direction of the first conveyor belt to a terminal portion. The second conveyor belt includes a second conveyor belt and a third conveyor belt extending rearward from a lower end portion of the second conveyor belt. A cutting apparatus is provided below the third conveyor belt, and a cutting apparatus of the cutting apparatus is provided. It is characterized in that a pair of left and right guide bodies whose passages can be freely expanded and contracted according to the size and shape of the agricultural product are provided on the front side.

[0006]

With the above construction, in the agricultural product harvesting machine of the present invention, the harvesting / conveying zone is constituted by the first conveying belt, the second conveying belt, and the third conveying belt, and the third conveying belt is used. By providing a cutting processing device below the conveyor belt of, by providing a pair of left and right guide bodies in which a passage can be expanded and contracted according to the size and shape of the agricultural product on the front side of the cutting processing device,
The front and rear alignment of the harvest carried by the harvest / transport zone is 3
As a result, the crops supplied to the cutting processing device are placed in a substantially fixed posture, and the cutting processing device performs the cutting stably, thus improving the working accuracy.
