2. Description of the Related Art Conventionally, vines, stems, leaves, and weeds of grown potato roots are prevented from wrapping around the excavation conveyor of the harvesting machine before harvesting the potato crops that are agricultural products. Therefore, it is necessary to remove vines, stems, leaves and weeds just before harvesting as a preparation. Also, these vines, stems, leaves and weeds grow along the ground, extend through the ridges to the adjacent ridges, and are entwined with the vines, stems, leaves and weeds of the peony roots in the adjacent ridges, Occasionally the furrows were closed. As a processing machine for removing vines, stalks, leaves and weeds in such an overgrown state, a foliage processing machine of Jitsukaihei 6-81219 is known. In this foliar treatment machine, a sandwiching device 41 composed of a pair of endless conveyors 13 whose conveyor faces are opposed to each other and whose opposing faces are both moved rearward is arranged so that the interval between the opposing faces of each sandwiching device 41 corresponds to the ridge interval. Guides are provided at the ridge groove positions provided between the ridges so that the holding device 4
A cutting blade 5 is provided on both outer sides of 1. As a result, the cutting blades 5 provided on both outer sides of the holding device 41 directly cut the vines, stems, leaves, and weeds that have grown naturally across the furrows without tension. There was a problem that it was difficult to cut. In addition, since the vines, stems and leaves that have grown laterally to the adjacent ridges that cross the ridges, which hinder the running of this vine stalk and leaf processing machine, are growing along the ground, the cutting blade 5 Regardless of the rotary rotary blade or the hair clipper hair clipper, the blade surface had to be provided so as to contact the ground. For this reason, there is a problem that the blade surface of the cutting blade 5 comes into contact with the ground, soil, sand, and pebbles damage the blade surface, the cutting force is reduced, and a load is easily applied. Further, if the cutting blade is a rotary blade, grown vines, stems, leaves, and weeds are entangled with the rotary shaft of the cutting blade, which impedes the rotation of the cutting blade and reduces the cutting efficiency. Further, when the cutting blade 5 is inserted into the ground, there is a problem that pebbles and soil scatter without a safety cover.

A forward / reverse bevel mission 19 for rotating the pull-out belt 3 and the scraping belt 4 is provided, and a chain 20 for transmitting the drive of the forward / reverse bevel mission 19 is provided with a sprocket 27.
The sprocket 27 is interlocked with the pull-out belt 3 and the scraping belt 4 via the.

In order to use the vine foliage processing machine 1 of this embodiment, as shown in FIGS. 1 and 2, the sliding tool 6 is arranged in the furrow and the engine 28 is operated to be driven via the V-belt 22. The wheels 24 that rotate in the traveling mission 26 advance the vine stem / leaf processing machine 1, and the scraping belt 4 and the pulling belt 3 that rotate in opposite directions rotate from the ground toward the rear of the machine body 5. The rotary blade 11 also rotates in the flexible tube 15 connected to the rotary shaft 16 rotated via the V belt 21 from the intermediate shaft 25 rotated via the V belt 23 by the operation of the engine 28. Rotate with 14. Since the inner guide rod 7 and the outer guide rod 8 are slanted and extended from the sliding tool 6, if the sliding tool 6 travels on the upper surface of the furrow, it includes those grown so as to traverse the furrow along the ground. under the vine shoots 43 across the furrows and sliding device 6 travels, vine shoots 43 with the guide rod 7 and the outer guide bar 8 crossing the ridges groove inner extending from the sliding member 6
As well as giving tension, the inner guide rod 7
Rotary blade 1 with a blade surface protruding from the surface connecting the outer guide rod 8 with
The vine stem and leaf 43 in a state of being tensioned with 1 is cut.
The lifted vine foliage 43 is entirely guided by the guide piece 13 to the blade surface, so that the vine foliage 43 is cut without being passed over the rotary blade 11. Further, since the rotary blade 11 is rotated toward the guide piece 13 as shown in the figure, even if the tensioned vine leaf 43 advances to the guide piece 13 without being cut, it stops at this guide piece 13. The cutting blade 11 can easily cut the vine foliage 43. As the cut vine foliage 43 moves laterally away from the rotary blade 11 through the inner guide rod 7 or the outer guide rod 8 as the machine body 5 travels, it is entangled with the central axis of the rotary blade 11. Prevent. Vine leaf 4 after cutting
Those located on the inner guide rod 7 side are guided by the inner guide rod 7 to the introduction port of the scraping and conveying section 2 so as to be raised to the ridge 44 side. Further, since the central axis of the rotary blade 11 is covered with the cover 12 and the drive wire 14 is protected with the flexible tube 15, the entanglement of the vine stem leaf 43 is further prevented. Scraping belt 4
The vine stem leaf 43 guided by the inner guide rod 7 is scraped, and the vine stem leaf 43 pulled out by the scraping and feeding unit 2 is also pulled by the pulling belt 3 which also rotates in the opposite direction. In the region 41 where the lower end of the scraping belt 4 is arranged, even the vine foliage 43 inclined by the scraping projection 31 provided on the scraping belt 4 can be surely guided and introduced between the scraping belts 4.

In the region 42 where the surfaces of the pull-out belt 3 are in contact with each other, the introduced vine stem leaf 43 is strongly clamped for pulling-out work, but the surface of the pull-out belt 3 is an elastic body, which is a convex portion or a concave portion, respectively. Since there is a portion and they are fitted to each other in the vertical direction, the clamping force against the vine foliage 43 is extremely strong, and since the pressing roller 32 strengthens the belt contact surface, pulling-out error does not occur. Further, the vine stem leaf 43 does not fall off during the carrying work.

During the work of pulling out the vine foliage 43, the potato root vegetables 4
When the pull-out belt 3 bites the multi-film stretched to the ridge 44 for cultivating No. 5 to prevent lowering of soil temperature in winter and enables early shipment with a high shipping unit price, or pebbles on the ridge 44, etc. , The V belt 22 for transmitting power from the engine 28 to the traveling mission 26 is loosened to stop the traveling of the machine body 5, and the claw clutch lever 33 incorporated in the forward / reverse bevel mission 19 is switched in the reverse direction as shown in FIG. As a result, the output shaft 36 whose meshing with the bevel gear 34 of the input shaft 37 driven by the engine 28 via the V-belt 23 is reversely rotated, and the chain 20 is reversely rotated to interpose the sprocket. The pull-out belt 3 which is interlocked with 27 reversely rotates, and along with that, the scraping belt 4
Also rotates in reverse. As a result, the multi-film or the small stones drawn by the pull-out belt 3 can be discharged.

When the pull-out belt 3 and the scraping belt 4 rotate in the reverse direction and spit out the multi-film or small stones, the claw clutch lever 33 built in the forward / reverse bevel mission 19 is returned to the original state, and the forward rotation is generated. Engine 2
V-belt 2 for transmitting power from 8 to traveling mission 26
2, the vine foliage processing machine 1 is returned to forward traveling, and with it, the pulling belt 3 and the scraping belt 4 also rotate from the original ground part toward the rear part of the machine body 5.
Therefore, as in the prior art, the multi-film, pebbles, etc. are lifted up together with the vine leaf 43 on the pull-out belt 3, which causes unreasonable force to each part of the machine, and in the worst case, damages the vine leaf processor 1. You can solve the problems that have become commonplace.

Since the sliding tool 6 is expandable and contractible from the locking portion 9 adjusted by the locking bolt 10, the length may be adjusted according to the height of the ridges 44. The height of the cutting blade 11 can be adjusted by adjusting the height adjusting portion 17 adjusted by the adjusting bolt 18 and sliding the cutting blade 11 along the sliding tool 6. Further, the adjustment of the cutting blade 11 in the left-right direction can be easily performed because both are moved to the position in the left-right direction when the height of the rotary blade 11 is adjusted. Further, the cutting blade 11 is driven by using a power transmission cable that rotates the rotary blade 11 with a drive wire 14 that is rotatable in the flexible tube 15. Since this drive transmission cable can be bent freely, bending or stretching of the drive transmission cable does not hinder the change of the mounting position of the rotary blade 11. Also drive wire 14
Is rotatable in the flexible tube 15 in the bent state, the rotary blade 11 can be rotated even when the power transmission cable is in the bent state, and the mounting position of the rotary blade 11 can be changed. Easy to do.
