That is, the raising device 400, the foliage cutting device 35, and the foliage discharging device 31 can be moved up and down while keeping the angles, and can follow the unevenness of the farm scene at a constant angle.

  Then, in order to adjust the cutting height by the foliage cutting device 35 to be described later, the support arms 66 and 66 are protruded forward from the left and right side portions of the transport frame 30, and brackets 71 and 71 are formed at the front ends of the support arms 66 and 66, respectively. The support rods 67 and 67 are attached to the brackets 71 and 71 in a substantially vertical direction. Slide shafts 67a and 67a are inserted into the support rods 67 and 67, and gauge rings 68 and 68 are attached to the lower portions of the slide shafts 67a and 67a. The sliding shafts 67a and 67a can be slid up and down by rotating handles 69 and 69 provided on the upper portions of the support rods 67 and 67. The height of the gauge wheels 68 and 68 is adjusted to the height of the rod D. The height of the working unit 4 can be changed, and the cutting height of the foliage portion 10b can be adjusted. However, it is also possible to provide a motor instead of providing the handle 69 and change the height of the gauge wheel 69 by rotating the motor.

  The lower ends of the gauge wheels 68 and 68 are located below the lower end of the raising device 400 (the lateral turning raising device 40 and the vertical turning raising device 50) and protrude outward, which is obstructive when turning or moving. May be. Therefore, the gauge wheels 68 and 68 can be lifted upward. That is, as shown in FIGS. 1 and 6, the rotary shaft 72 and the boss 73 project in parallel from the upper and lower middle portions of the support rod 67 to the outer side, and the rotary shaft 72 is connected to the bracket 71 (or the support arm). 66) is rotatably supported.

The power from the engine 7 is transmitted from a sprocket fixed to the other end of the intermediate shaft 17 to a sprocket fixed to one end of the rotary shaft 32 via a chain.

  A cylindrical feed shaft 33 is concentrically fixed on the rotating shaft 32, and a spiral blade 34 is fixed on the feed shaft 33. The spiral blade 34 is fixed on the feed shaft 33 symmetrically. That is, the spiral blade 34 is configured with forward and reverse screws on the left and right sides, and by rotating the feed shaft 33, the cut foliage portion 10b is divided from the center to the left and right to be sent to the side. The lower and rear sides of the outer peripheral rotation trajectory of the spiral blade 34 are covered with a curved feeding case 14 and fixed to the transport frame 30.

  Scrapers 36 are provided on the left and right ends (downstream ends) of the spiral blade 34. The scraper 36 is made of an elastic plate such as rubber or synthetic resin, and is disposed obliquely with respect to the rotation shaft 32 to reduce the gap between the inner surface of the transport frame 30 that becomes the side plate of the feed shaft 33, The foliage portion 10b sent to the left and right ends by the rotation of the spiral blade 34 is scraped so as to be sent to discharge ports 37 and 37, which will be described later, so that the left and right ends of the lateral feed auger are not clogged.

  Discharge ports 37 and 37 are opened at the lower portions of the transport frames 30 and 30 covering both the left and right sides of the feed shaft 33 and the left and right sides of the feed case 14 so that the foliage 10b transported is discharged out of the machine. ing. The discharge port 37 includes a cutout portion 30a formed by cutting out the rear lower portion of the transport frame 30, and a discharge plate 14a configured to expand the discharge port 37 by projecting the left and right lower portions of the feed case 14 obliquely rearward and bulging. The cutout portion 30a is opened at a portion where the lower portion (about the lower half) of the spiral blade 34 is located in a side view. A regulating plate 15 is disposed at a side of the discharge port 37 with a predetermined space. In other words, the regulating plate 15 is disposed so as to face the discharge port 37, so that the foliage portion 10b discharged from the foliage discharge device 31 enters the traveling portion 2 and does not adversely affect the traveling. In this way, even if the cut foliage portion 10b is sent to the side by a lateral feed auger, it can be reliably dropped into the furrows from the discharge openings 37 and 37 that are opened to a large extent, and the travel plate 2 has a restriction plate. 15 to prevent the crawler 26 from stepping on the foliage 10b when traveling between the furrows. Therefore, the discharged foliage portion 10b is not stepped on and buried, and post-processing can be facilitated, and height fluctuation due to stepping on the traveling portion 2 can be prevented.

  The restriction plate 15 has a larger area than the discharge port 37 in a side view, and extends from the discharge port 37 to the vicinity of the lower position of the wheel 23 and extends from the front to the rear of the traveling unit 2 for conveyance. A discharge space is formed at a predetermined interval from the frame 30 and is fixed to the track frame 22 and the vertical frame 21 in the vertical direction.

  Thus, by rotating the feed shaft 33, the foliage portion 10b scraped from the front is fed to the left and right outwards by the feed action of the spiral blade 34, and falls between the discharge ports 37 and 37. At this time, the foliage portion 10b does not enter the traveling portion 2 by the restriction plate 15 so that it does not interfere with the traveling drive and is not stepped on, so that the foliage portion 10b is collected and processed after the cutting operation. It can be easily removed.

  The foliage cutting device 35 includes a clipper-type reciprocating blade composed of a lower blade 35a and an upper blade 35b. In the foliage cutting device 35, a saw blade-like lower blade 35 a having a large number of V grooves 35 c, 35 c... In the left-right direction is fixed to the conveying frame 30, and the saw blade-shaped upper blade 35 b is driven to reciprocate left and right. The upper blade 35b is engaged with an eccentric shaft disposed at the center of the left and right, and a gear box 18 (FIG. 7) is provided at the center of the left and right of the intermediate shaft 17. Power from the engine 7 is transmitted through a transmission shaft or the like extending forward and downward from the gear box 18, and the upper blade 35b is slid back and forth by the rotation of the eccentric shaft so that it can be cut.

  The height of the foliage cutting device 35 is higher than the bottom plate of the feed case 14 so that the cut foliage portion 10b can easily enter the foliage discharge device 31. That is, the foliage portion 10b after being cut naturally falls into the front portion of the feed case 14 and easily enters the feed case 14, and is sent to the left and right outer sides while being pushed downward by the spiral blade 34 of the lateral feed auger. It is lifted at the front part of the feed case 14 so that clogging or the like does not occur. As described above, since the working unit 4 is moved up and down in a parallel state by the parallel link, the height relationship between the foliage cutting device 35 and the feed case 14 is maintained, and after cutting even if the cutting height is changed The foliage portion 10b is made to fall into the feed case 14 so that it can be easily taken in.

Therefore, the stems and leaves 10b collected in a bundle shape can be cut into a bundle shape by reciprocating the upper blade 35b in the V-groove 35c, and can be cut with a clean cut surface in the horizontal direction. It can be sent to the foliage discharging device 31 without being separated.

  Further, the rigidity of the upper guide rod 461 is smaller than that of the lower guide rod 462, so that the upper portion of the ball portion 10a is reliably guided to the center of the strip by the lower guide rods 462 and 462, and strongly The foliage portion 10b is bent in the sandwiched state so as not to cause a cutting error, and the upper guide rods 461 and 461 can be bent and pinched in accordance with the volume so that the upper portion of the foliage portion 10b does not fall apart. .

  Further, since the guide plate 451 is caused to be adjustable in height and attached to the case 402, the guide plate 451 and the upper guide rod 461 and the lower guide rod 462 attached to the guide plate 451 are integrally formed with the height of the heel D or the onion. The height can be adjusted in accordance with the size and the like, and the foliage 10b can be guided and taken in at an appropriate height position.

  In addition, the stem and leaf portion 10b that has been raised is cut by the stem and leaf cutting device 35 at a predetermined height, but the cut leaf and leaf portion 10b and foreign matters are transported upward while being caught by the tines 46a, and the drive pulley 44 and There is a risk of entanglement with the drive shaft 43 or the like. Therefore, as shown in FIGS. 10, 11, and 12, the trajectory of the tip of the tine 46 a of the trigger belt 46 of the left trigger body 41 and the rotation of the right trigger body 42 are formed at the upper part of each strip of the lateral trigger apparatus 40. An extruding body 463 penetrating in the front-rear direction between the tip rotation trajectories of the tine 46 a of the raising belt 46 is arranged to cause the foliage 10 b and foreign matter lifted by entanglement to be separated from the belt 46.

  Specifically, the exclusion body 463 is made of an elastic steel bar, and one end of the exclusion body 463 is fixed to a stay 452 provided on the upper front surface of the raising case 402, and the exclusion body 463 is L-shaped. The other end is inserted between the left raising body 41 and the right raising body 42 and is extended upward and rearward. In other words, the rear portion of the exclusion body 463 extends from the front to the rear and extends upward at the left and right centers of the left trigger body 41 and the right trigger body 42, that is, the left and right central portions of the strip upper portion. In other words, the exclusion body 463 is disposed so as to penetrate the range of action of the tine 46a of the left trigger body 41 and the upper part of the range of action of the tine 46a of the right trigger body 42 in the front-rear direction. However, although one end of the exclusion body 463 is attached to the raising case 402, it may be attached to the front cover 403 or the raising frame 401, and is not limited as long as it is attached so as to penetrate the upper left and right centers of the strip. .

  As described above, in the lateral rotation trigger device 40 including the drive pulley 44 and the driven pulley 45 on the pair of right and left trigger cases 402, and the trigger belt 46 with the tine 46a wound around the drive pulley 44 and the driven pulley 45, respectively. An exclusion body 463 that penetrates from one side to the other is provided in the left and right central upper part of the strip on which the foliage 10b is caused, and the exclusion body 463 is in contact with the tine 46a of the left and right trigger belt 46 so that it falls down. The foliage portion 10b, foreign matter, etc. that are hooked on the tine 46a and lifted upward when the foliage portion 10b is raised hit the exclusion body 463 and are gradually guided to the tip side of the tine 46a and moved away from the tine. 46a falls off from 46a and gets caught in the drive pulley 44 and causes the belt 46 to be entangled. It is possible to stop.

  And since the said exclusion body 463 is comprised with the bar | burr which has elasticity, the tine 46a of the right and left raising belt 46 contact | abuts the exclusion body 463 at the time of a raising action, but it elastically deforms and does not damage the tine 46a, and it is entangled The stems and leaves 10b, impurities, etc. can be rejected by being bounced at the tip of the exclusion body 463.
