DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester mainly configured to extract root vegetables such as ginseng and radish to perform leaf cutting.

[0002]

2. Description of the Related Art Japanese Patent Application No. Hei 3-
No. 341628, a harvesting transporting device is provided on one side of the machine for holding the foliage of root vegetables such as carrots and radishes, pulling it obliquely upward at the rear of the machine and suspending and transporting it. A leaf cutting device that cuts the foliage of root vegetables from the transport device, a collection unit that collects root vegetables from the leaf cutting device, and a foliage that discharges the cut foliage from the leaf cutting device to the outside of the machine body The present applicant has previously proposed a root vegetable harvesting machine provided with a transport device.

[0003]

In the above-mentioned root vegetable harvesting machine, in order to align the cutting position of the root vegetable toward the leaf cutting device, a positioning conveyor mechanism having a roller conveyor structure is provided, and the root vegetable rises as it is transported rearward. At the end, the root vegetable head is configured to be in a contact conveyance state in which it comes into contact with the roller. However, since a spring structure is employed to press the left and right rollers against each other to clamp the foliage, the rollers and the chain link supporting the rollers are separated in the direction of the rotation plane of the chain, and the rotating portion of the starting end sprocket In such a case, a large gap is formed between the adjacent rollers in the transport direction, and there is a case where the foliage is sandwiched in the gap. An object of the present invention is to make it possible to satisfactorily convey a root and leaf portion of a root vegetable so as not to be caught between adjacent rollers in the conveying direction.

[0004]

In order to achieve the above object, according to the present invention, a leaf portion of a root vegetable is sandwiched between a pair of left and right front endless rotating belts which are driven to face each other while being inclined rearward and upward. And a pair of left and right rear endless rotating belts and a pair of left and right alignment transport mechanisms disposed below the pulling unit for pulling the root vegetables upward while pulling the root vegetables from the ground. And a transport device for transporting the root vegetables sent from the pull-out portion rearward by nipping and transporting the upper portion of the leaf portion by driving the pair of rear endless rotating bands while guiding and guiding between the alignment transport mechanisms. Provided, respectively, the vertical interval between the pair of rear endless rotating bands and the pair of alignment transport mechanisms,
The rear endless rotation band and the alignment conveyance mechanism are relatively arranged so that the rear endless rotation band becomes wider toward the lower side in the conveyance direction. The leaf holding force is set by a pair of rear endless rotating bands so that the downward movement from the end is allowed, and the alignment transport mechanism is wound endlessly over the front and rear wheels. A rotatable belt and a number of rotatable rollers supported in a protruding state by the endless rotatable band, and a root vegetable portion located between the rollers of the left and right alignment transport mechanism is nipped. The root vegetable harvest is set so that the left and right endless rotating belts are arranged relative to each other and the direction of the rotation axis of the rollers is set so that the vertical movement of the root vegetable leaf portion held by the alignment conveyance mechanism is allowed. Endless rotating belt in the alignment transport mechanism It is an characteristic configuration that is provided with guide means for preventing the root vegetable leaves the expanded gap between the rollers adjacent enters at the site to be wound on the wheel body.

[0005]

In other words, since the foliage is prevented from being caught between the rollers adjacent in the transport direction by the guide means, the root vegetables can be delivered to the alignment transport mechanism without inconvenience such that the root vegetable head does not come into contact with the rollers. In the cutting device portion, the contact conveyance state in which the root vegetable head is in contact with the roller can reliably appear.

[0006]

Therefore, a root vegetable harvesting machine for mechanizing a series of processes from the extraction of the root vegetables from underground to a position just before the post-processing such as a cutter device is provided. The position aligning and transporting mechanism for alignment can be provided in a state where it functions reliably and satisfactorily.

[0007]
