BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for digging out root vegetables such as potatoes, sweet potatoes, onions and the like in soil and storing them in a container.

[0002]

2. Description of the Related Art Conventionally, for example, potatoes, sweet potatoes,
When harvesting root vegetables such as onions, a digging machine is attached to the rear part of the cultivator, and the worker pushes the cultivator equipped with the digging from behind to move in the field while digging the root vegetables in the soil. .

Since the root vegetables digged by the digging machine are left on the surface of the earth, they are picked up by the input after the digging and stored in the container. For this reason, the conventional root vegetable harvesting work has been performed twice, digging and collecting.

Further, since the digging machine is provided at the rear part of the cultivator, the weight of the tire of the cultivator presses the ground surface of the root vegetables just before digging.

Further, since the excavator is provided at the rear of the cultivator, as shown in FIG. 11, the front end portion of the field cannot be excavated by the length of the cultivator, and the cultivator equipped with the excavator is installed. Since the work is performed by pushing from the rear side, when the traveling direction of the cultivator is reversed by 180 degrees, that part of the field becomes a scaffolding part for the operator who pushes the cultivator, and it is not possible to excavate in continuous work. Therefore, as shown in FIG. 12, the root vegetables are cultivated at both ends of the field at right angles to the root vegetables cultivation direction in the center of the field. And the harvesting work is then done separately.

[0006]

[Problems to be Solved by the Invention] However, the conventional harvester merely mounts the digging machine at the rear part of the tiller, and the digging machine is, for example, potato in the soil,
The root vegetables such as sweet potatoes and onions are only dug out on the surface of the earth, and the root vegetables that have been dug out are left unattended on the surface of the earth. Therefore, it is necessary to collect them. Work was needed.

Further, as described above, since the digging machine is provided at the rear part of the cultivator, there is a risk that the root vegetables in the soil may be damaged by the weight of the tire of the cultivator immediately before the digging machine digs the root vegetables.

Further, as described above, since the root end of the field cannot be dug out at the front end and rear end of the field with respect to the traveling direction of the cultivator, the root field can be planted in the center of the field with respect to the planting direction of the root field. The root and root must be planted at right angles at the front end and rear end, which requires time and effort for planting root vegetables, and the excavation work is separate only for that part, so continuous excavation work is not possible. However, it took a lot of time to dig out.

The present invention has been made in view of the above problems to solve the problems, and the purpose thereof is to dig root vegetables and harvest work at the same time. Moreover, the weight of the cultivator's tires does not damage the root vegetables in the soil, and both end parts of the field can be planted in the same direction as the center of the field, simplifying the planting work and continuing it. The purpose of the present invention is to provide a harvesting machine that enables the digging and the harvesting work to be performed, and saves the trouble of separately performing the digging and the harvesting work later.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a side conveyor 3 having a digging claw 5 formed at a front end thereof on a side portion of a traveling machine 2 so as to be vertically movable. Side pieces 8 for expanding and contracting the width interval of the side conveyor 3 are provided on both sides in the latter half of the part conveyor 3, and the rear conveyor 4 is connected to the rear part of the side conveyor 3 in a direction substantially perpendicular to the side conveyor 3. The rear conveyor 4 is provided with a sorting section 11 for soil and stones c and root vegetables a, and a container mounting section 13 for storing root vegetables is provided below the rear end of the rear conveyor 4.

[0011]

The present invention having the above-described structure operates as follows. That is, since the side conveyor 3 having the digging claw 5 formed at the front end is provided on the side of the traveling machine 2, the root vegetable a just before digging is not damaged by the weight of the moving harvesting machine 1. In addition, since the front end and the rear end of the field can be dug out, both end parts of the field also work in the same planting direction as the center of the field.

This is provided for a worker to sit here when sorting is performed with the rear conveyor 4, and the sorting worker sits on this sorting work chair 14 to sort the work on the traveling harvester 1. Can be done easily.

Next, the operation based on the configuration of the above embodiment will be described below. When using the harvesting machine 1 to harvest the root vegetables a, the side conveyor 3 is lowered and the excavated nails 5 formed at the front end of the side conveyor 3 are put into the soil of the field. After that, when the traveling machine 2 of the harvester 1 is caused to travel, the side conveyors 3 travel integrally with the traveling machine 2 in the field in a straight line direction. As the side conveyor 3 runs, the digging claw 5 digs out the root vegetable a from the soil of the field, and the digged root vegetable a is scooped by the digging nail 5 and inside the endless conveyance path 6 at the rear of the digging nail 5. Sent to.

The root vegetables a are conveyed by the endless conveying path 6 inclined upward of the front half 3a of the side conveyor 3, but since the front half 3a inclined upward is provided with the circulation type lifting mechanism 7. Since the root vegetable a is pushed and supported by the push-up plate 7b of the circulation type lifting mechanism 7, the root vegetable a is reliably sent to the rear half 3b of the side conveyor 3 without rolling down.

Although the soil and stones c excavated together with the root vegetables a are included in the movement on the endless transport path 6, the soil and stones c
Most of them fall from the gap between the horizontal bars 6b forming the endless conveyance path 6 while moving on the endless conveyance path 6.

The root vegetables a and some soil lumps and stones c conveyed in the endless conveying path 6 of the side conveyor 3 enter the rear conveyor 4 connected to the rear part thereof. At this time, when a large amount of root vegetables a and lumps of soil or stones c are sent in the endless transport path 6 at one time, a rearrangement plate provided at the connecting portion between the side conveyor 3 and the rear conveyor 4 Some root vegetables a and soil lumps and stones c are stopped by 12, and an appropriate number of root vegetables a and soil lumps and stones c are sequentially sent to the rear conveyor 4. In the rear conveyor 4, the sorting unit 11 removes a part of the lumps of soil or stones c sent together with the root vegetables a. This sorting work can be performed while the worker is sitting on the sorting work chair 14. This work is performed while the harvester 1 is running.

Then, after the lumps of soil and stones c have been removed in the sorting section 11, the root vegetable a moves toward the end of the rear conveyor 4, and is installed on the container mounting section 13 therebelow from the end. Enter the container b. In this way, it is possible to perform both the excavation work and the harvest work at the same time.

The present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the brush 9 is the rear half 3b of the side conveyor 3.
However, it may be omitted if necessary.
