As a result, the opposing portions of the belts 66 and 66 move from the front to the rear at the same speed as the nipping and conveying belt 68 while gradually reducing the interval.
0037]
  Next, a usage example in the case of processing a sweet potato vine with the above-described vine treatment machine of the present invention will be described. As shown in FIG. 5, the two traveling wheels 7 and 7 are positioned in the left and right grooves m of the kite h so as to straddle the kite h, and the left and right upper support rods 52 and 52 are moved in the traveling direction, for example. 1 and 5 is fixed to the same body as the chain case 29 by a restricting means (not shown), and the state shown in FIGS. 1 and 5 is obtained.
0038]
  Further, the swing operation handle 25 is operated to swing the vine processing mechanism portion C around the horizontal rotation shaft 15 so that the left and right drum rollers 34 are brought into contact with the left and right slopes of the hail h. At this time, the support roller 13 is brought into contact with the heel h.
0039]
  After that, the aircraft is run and each part is in an operating state. As a result, the weed board 4 sequentially digs up the vine t rooted in the groove m, the vine t stepped on the traveling wheel 7 in the previous stroke and buried in the soil, and guides it to the cutting part 3a and scrapes it. The device 47 continuously scrapes the vine t prospering on the upper surface of the heel h and its right and left slopes with the protrusions of the scraping belts 46, 46, and then transports it backward and obliquely upward.
0040]
  As shown in FIG. 6, the cutting part 3a moves forward while cutting the vine t crossing the groove in the groove m, and the scraping device 47 pulls the vine crossing the cutting part 3a. Since it acts, the vine t is easily cut and is cut accurately.
0041]
  The vine t thus scraped into the scraping device 47 is eventually supplied to the transport start end of the sandwiching and transporting device 69. Thereafter, the sandwiching and transporting device 69 strongly sandwiches these vines t and transports them backward and obliquely upward. Then, pull it up sequentially.
  As this pulling progresses, a strong tensile force acts on the vine vine that is pressed by the drum roller 34 in the vicinity of the left and right sides, and the vine ridge is torn off. Done along.
  Instead of this tearing, it is also possible to connect and disconnect with an appropriate cutting device.
0042]
  The nipping and conveying device 69 conveys the vine t after the tearing process from the position of the wide pulley 27 (folded portion) to the conveyance end through the position of the wide pulley 50 (second bent portion).落下 Drop it on top.
0043]
  On the other hand, as shown in FIG. 7, the scraping device 47 holds the upper part of the vine t transported by the sandwiching transport device 69 and transports it to the position of the wide pulley 27 along the transport path of the sandwiching transport device 69. After this, the rear vine auxiliary transport device 67 receives the vine t before reaching the transport end of the scraping device 47, and also holds the upper portion of the vine t transported by the sandwich transport device 69 and transports the sandwich transport device 69. It is transported to the transport terminal of the nipping and transporting device 69 along the path and released.
0044]
  Thus, the scraping device 47 and the rear vine auxiliary transport device 67 transport the vine auxiliary while transporting while holding the upper part of the vine t sandwiched and transported by the sandwich transport device 69 in the entire transport path of the sandwich transport device 69. It functions as a device.
  At this time, the holding and conveying device 69 andScraping device 47 and rear vine auxiliary conveying device 67For example, the vine t transported at the top and bottom is supported at two places up and down, for example, about 10 cm apart, so that it is held in a relatively standing shape and hardly hangs down to the left and right, and is efficiently transported without spilling or tangling Will be.
0045]
  By the way, also when processing the vine t of the adjacent hail h on which the vine t1 processed in the previous process is processed, the processing is performed in accordance with the above. In this case, the amount of the vine t on the heel h is increased, but the scraping device 47 and the rear vine auxiliary transport device 67 are sandwiched by the sandwich transport device 69 and are transported. In order to effectively hold and convey the entangled vine t1 mounted on the vine t, these vine t and t1 are also efficiently conveyed without spilling from side to side or tangling. Become.
0046]
  Thus, even if the amount of the vine on the hail is about 2 to 3 times, it is transported and removed without any trouble. Therefore, the vine t can be removed in a wide range by the nipping / conveying device 69, and can be dropped to a place where work such as vine removal and digging is made efficient.
