Abstract

PURPOSE:To cut the stalk and leaf part of potato by accurately pulling out exclusively the stalk and leaf part from the root while leaving the potato in the ridge soil and supplying the stalk and leaf part to a cutter. CONSTITUTION:The objective machine for treating the stalk and leaf of potato, etc., is provided with a stalk-pulling apparatus 1 to pull out the leaf and stalk of potato, etc., upward, a soil-pressing plate 2 to press the soil surface of the root part of the stalk to be pulled out with the stalk-pulling apparatus 1 and a cutter 3 to cut the pulled stalk and leaf.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foliage processing machine for potatoes and the like.

[0002]

2. Description of the Related Art Prior to harvesting potatoes, a method for harvesting potatoes in advance and harvesting potatoes underground is known in the prior art (Japanese Patent Application Laid-Open No. HEI 3-hei).
247212), the fact that the foliage after the extraction and separation is scattered on the ridge surface is an obstacle to the excavation of potatoes. According to the present invention, the potato part is left in the ridge soil, only the foliage is removed, and the potato is cut with a cutter.

[0003]

The present invention is directed to a stem pulling device 1 for pulling upwards the leaves of a potato or the like, an earth pressing plate 2 for pressing the soil surface at the root of the stem to be pulled out by the stem extracting device 1, and A foliage processing machine for a potato or the like is provided with a cutter 3 for cutting the foliage after withdrawal.

[0004]

[Operation and effect of the invention] The machine body is advanced along the ridges of potato cultivation. When the stem pulling device 1 pulls out the stems and leaves on the soil surface, since the root is pushed by the soil pressing plate 2, only the stems and leaves are pulled out and the potatoes are left in the ridges. Not exposed on the soil surface. The foliage part thus extracted from the soil surface is supplied to the cutter 3 and finely cut.

As described above, the stems and leaves before harvesting the potatoes are pulled out upward by the stem pulling device 1 while the roots are held by the soil pressing plate 2, so that the potatoes are left in the ridges. Then, only the foliage part can be separated and subjected to cutting treatment, and the foliage part can be cut and sprayed on the ridge surface to reduce obstacles at the time of harvesting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2, with respect to a machine body having front wheels 4 and rear wheels 5, a grass plate 6, a stem pulling device 1, and an earth pressing plate are provided from a front portion to a rear portion. 2, the transport device 9, the cutter 3, and the like are provided. The sprouting board 6 straddling the right and left sides of the ridge A scoops the stems and leaves of potatoes vegetated on the ridge A while scooping them to the central part and guiding them to the rear part of the stem pulling device 1.

The stem pulling device 1 is constructed so that a pulling disk 7 formed in an eight shape so as to open the front side and bring the rear side closer to each other is driven to rotate around a drive shaft 8 at the central portion, and a rear approaching portion. Is driven so that
The foliage part sandwiched between them is pulled out upward. The transport device 9 brings the pair of left and right belts close to each other,
The pull-out disc 7 holds the pulled-out foliage and transfers it to the rear side, and supplies it to the disc-shaped cutter 3. The disc cutter 3 cuts the supplied foliage by arranging a large number of disc blades on the left and right parallel cutter shafts and rotating them so as to approach and face each other.

The earth pressing plate 2 has a form that extends along the ridge surface and presses the left and right bases of the foliage to prevent the soil and potato portions from floating upward during foliage withdrawal. When the vehicle is moving, the upper push plate 2 slides so as to make sliding contact with the ridge surface on both left and right sides of the root portion. The wheels 4, 5, the stem withdrawing device 1, the conveying device 9, the cutter 3 and the like are configured to be transmitted by the power take-out device of the tractor body. In such a working machine body, a mounting member 18 is connected to a top link, a lower link, or the like of a tractor, and the power take-off shaft is connected to the input shaft 1
9 is linked and linked.

3 to 5 are different from the above example in that
The stem pulling device 1 is axially mounted so that a pair of left and right rolls 10 are brought close to each other so as to rotate along an inclined surface in which the front side is lowered and the rear side is raised. It is pulled out as it is thrown to the upper part. The rotating peripheral surface of the roll 10 has an elastic material such as a rubber material,
The unevenness is formed, and the left and right pairs are occluded so that rotation is transmitted. The foliage pulled out by the roll 10 and released is received by the cutter 3 and cut.

6 to 8 are different from the above example in that
The stem pulling-out device 1 is provided with a scraping tine 13 around a rotary shaft 12 that rotates close to the upper surfaces of the ridge A and the groove B, and slits 15 along the upper part of the scraping tine 13 at regular left and right intervals. The guide plate 14 is formed and arranged, and the front end surface 20 of the guide plate 14 is curved downward in an arc to easily scoop up the foliage. A weeding plate 6 is integrally formed at the front ends of the left and right soil pressing plates 2, and a weeding blade 16 that bites into the groove B is provided at the outer end of the scraping tine 13. The cutter intervenes in each slit 15 and rotates at the rear end portion of the guide plate 14, receives the foliage guided and conveyed by the upper surface of the guide plate 14, and cuts it. Reference numeral 17 is a transmission case for transmitting the shaft 12 of the scraping tine 13.

The scraping tines 13 may be made of an elastic material such as rubber.
