DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a potato vine extractor for cutting a vine extending to an adjacent ridge or a vine extending from an adjacent ridge when harvesting a potato planted in a ridge. The present invention relates to a vine cutting device.

[0002]

2. Description of the Related Art A pair of left and right tines are scraped by a scraping device in which a pair of right and left tines are plane-rotated, and are pinched by a pinching device in which a pair of left and right belts are turned in a plane. There is known a potato stem and leaf extracting machine that pulls the potato stem and leaf backward, but an attempt has been made to extract a potato vine with the potato stem and leaf extracting machine.

[0003]

However, unlike potato stems and leaves, potato vines are very long, and vines extending from an adjacent ridge and vines extending from an adjacent ridge are intertwined in a complicated manner. Therefore, if the potato stem and leaf extracting machine is diverted as it is, it cannot be pulled out well. The present invention solves such a problem, and attaches a vine cutting device capable of setting a drawing width.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a potato vine planted on a ridge which is raked by a pair of right and left tines by means of a plane rotating device. In a sweet potato pulling machine that pulls out by pinching with a pinching device that rotates in a plane , the pinching device is driven on both sides of the body.
Provide a crank that uses the drive shaft as the driving source, and
The force is applied by a rod that extends outside the pinching device within the width of the fuselage.
Drive that is provided at the front of both sides of the
Provided is a vine cutting device for a potato pulling machine, which is transmitted to a vine cutting device comprising a dynamic reciprocating blade .

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a sweet potato pulling machine showing one example of the present invention, and FIG. The potato extractor according to the present invention has a configuration very similar to a conventionally known potato stem extractor. That is, at the front part of the self-propelled body 12 supported by the large-diameter wheels 10 rolling on both skirts of the ridge, a pair of left and right tines 14 is provided with a scraping device 16 in which a part of the tine 14 is partially rotated on a plane of overlap. A pair of left and right soft belts 18 are provided behind the insertion device 16 and a pinching device 20 that rotates in a plane by abutting against each other.

A collecting and discharging device 22 is provided behind the pinching device 20 to collect and discharge a certain amount of the extracted vine.
The collecting and discharging device 22 includes a pair of right and left collecting plates 24. When the collecting amount of the vine becomes constant, the collecting plates 24 are automatically or manually operated.
Is rotated downward to release the vine placed thereon. For this reason, the pinching device 20 of the present example can be bent at the center so that the rear end faces the left and right collecting plates 24. In addition, the potatoes from which the vines were peeled are kept in the soil,
Harvested by hand or another harvester.

In addition, a vine 26 for separating vines that can be treated and vines that cannot be processed protrudes in front of the scraping device 16, and a gauge for setting the height of the airframe 12 is provided on the vine 26 and the like. A foil 28 is attached. Further, a steering handle 30 is provided rearward of the body 12.

According to the present invention, a vine cutting device 32 for cutting a vine extending to an adjacent ridge or a vine extending from an adjacent ridge and setting a drawing width is attached to both front sides of the body 12. .
The vine cutting device 32 may be any device that can cut the vine, but is roughly classified into a reciprocating blade and a rotary blade. The vine cutting device 32 in FIG. 1 and FIG. 2 shows a drive type reciprocating blade (hair clipper) 32,
A reciprocating blade 32 composed of a fixed blade 32a and a movable blade 32b is attached to the mounting plate 34 diagonally downward.

The movable blade 32b is forcibly reciprocated by using the drive shaft 36, which is upward in the middle of the clamping device 20, as a drive source. FIGS. 3 and 4 are cross-sectional views of the main part of this part. The crankshaft 40 is taken out from the drive shaft 36 by the bevel gear mechanism 38, the crank 42 is fixed to the crankshaft 40, and the movable blade 32b can be rotated by the arm 44. Thus, the crank 42 and the arm 44 are connected by the rod 46. Thereby, if the pinching device 20 is driven, the movable blade 3
2b reciprocates and cuts the vine with the fixed blade 32a.
The vine cut in this manner has a width that allows the vine to be pulled out, and can be satisfactorily pulled out by the scraping device 16 or the pinching device 20.

FIG. 5 is a plan view of a main part showing another example of the vine cutting device 32. In this example, a rotary blade (coulter) 32 is attached to the gauge wheel 28.
In this case, the coulter 32 is of a non-drive type, and rotates as the body 12 advances to cut the vine. In addition, other than the above, the coulter 32 without the gauge wheel 28 alone may be used.

FIG. 6 is a perspective view showing another example of the vine cutting device 32. In this embodiment, a driving type rotary blade 32 for forcibly rotating the rotary blade 32 is attached. In this case, the driving force is transmitted from the flexible wire 48
In the above description, the rod is used, but the rod may be used as described above. In addition, in the rotary blade 32 of this example, a protrusion 50 is formed on the circumference to increase sharpness,
Above the cover 5 which also serves as a vine
It is covered with 2.

[0012]

As described above, the present invention has been described above, that is, the processing width (pulling width) of the vine extending to the adjacent ridge or the vine extending from the adjacent ridge being intertwined with each other in a complicated manner. The vines within the processing width can be reliably extracted because the vines are extracted while cutting. This means
A conventionally known potato stem and leaf extractor can be made into a sweet potato extractor without much change, thereby contributing to a reduction in harvesting cost.
