[Prior art]

As a conventional foliar processing machine, for example, Japanese Patent Publication No. 59-39
As can be seen in Japanese Patent Publication No. 084, a pair of endless conveyor bodies on both sides for squeezing the foliage portion of an underground rhizome crop and transferring it to the rear side are arranged in the front portion of a machine frame on which wheels are mounted. There is a configuration in which a pair of guide bodies inclined rearward and upward are arranged on the front end side, and a transverse feed conveyor body is arranged on the lower side of the rear end.

[Problems to be solved by the device]

However, according to the foliage processing machine, first, the foliage part of the rhizome planted along the ridge is raised by a pair of guide bodies on both sides, and this foliage part is moved upward and backward with the circulation of the pair of endless conveyor bodies. Although it will be pulled out by transporting, the pair of guide bodies on both sides are composed of the inner side parts of the swarding rods on both sides facing each other, and the distance between them becomes narrower toward the rear. Since the foliage is not transferred to the pair of endless conveyor body start ends,
Further, the stem-leaved leaves that have been pulled out by the pair of endless conveyor bodies and transferred to the rear are transferred onto the transverse feed conveyor body from this start end and discharged one by one from the transfer end on the one end side thereof to the ground. Therefore, there is a problem in that the post-treatment work for collecting the stem-leaved leaves released to the ground requires a great deal of labor and time.

[Means for Solving the Problems]

Therefore, the present invention is directed to a scraping device that scrapes back the stems and leaves of a rhizome crop, a sandwiching device that sandwiches the stems and leaves that have been scraped by the scraping device, and transfers the stems to the rear, and this sandwiching device. The upper end of the extruded leaf transferred by the stem is transferred to the left and right sides of the fuselage behind the slant, and the rear end can be swung left and right. Correspondingly, the foliage treatment units, which are provided on the left and right sides and are configured to collect and discharge a fixed amount of the extirpated leaf portions sent out from the upper conveyance device, and to release the foliage treatment portions, respectively, on the traversable machine frame The above problem was solved by providing a foliage processing machine characterized by being arranged in a high slope.

[Action]

With the above configuration, the foliage of the rhizome crop is forcibly and smoothly scraped toward the front end of the pinching device by the raking device, and it is surely pushed in by the pinching device. Only the foliage part is transferred and pulled out while being pinched toward the upper rear, and the extruded foliage part is smoothly and surely inherited from the start end of the pinching device to the upper transport device, and the left and right sides of the aircraft It is conveyed toward the collecting and discharging device provided on one side,
The stem-and-leaves are discharged to the collecting and discharging device above the ground where a fixed amount is collected.

The scraping device 8 is composed of a pair of belts 14 with a radial scraping protrusion made of an elastic agent, which are wound around and fixed to the outer peripheral portion of the rotating body 13 attached to the rotary shaft 12, and are located on both sides of the front end of the foliage processing portion 7. As described above, the rotating shaft 12 is supported by the machine frame 6 or the connecting member, and the tip rotation trajectories of the belt 14 with the protrusions for scraping are overlapped with each other, and the tip rotation trajectory rises rearward when viewed from the side. Is composed of. As a result, the belt 14 with protrusions for scraping comes into contact with the foliage of the underground crop and is forcibly guided toward the pinching device 9 at the rear.

The pinching device 9 is provided before and after the machine frame 6 or this connecting member.
A pair of sprocket shafts 15 on both sides and a sprocket shaft drive shaft 16 are supported, and a pair of endless belts 17 with a wave protrusion made of an elastic material is wound between the sprocket shaft 15 and the sprocket shaft drive shaft 16 via a sprocket 18. Then
The pair of endless belts 17 with wave protrusions are configured such that the wave protrusions mesh with each other at adjoining portions and the meshing portions advance in the same direction, and the front end portion of the endless belt 17 with wave protrusions is a belt with a protrusion for scraping. 14 is located below the rear part and the rear end part is located above the rear part, and is obliquely installed so as to form a front low rear high slope. Thereby, at the front end portions of the meshing portions of the pair of endless belts 17 with wave protrusions,
Since the base of the foliage of the understory crop that has been scraped by the scraping device 8 is reliably pinched and transferred to the upper rear, the foliage remains upward with the root remaining on the ground side. Then, the stem-leaved leaves are transferred to the upper rear, and are transferred from the rear end to the upper transfer device 10. In addition, a root drop guide body 19 is supported below the front part of the pinching device 9,
Separation between the root portion and the foliage portion may be made more reliable. The root drop guide body 19 in this case is a pair formed by supporting the rear end portions of two bars arranged in parallel to the machine frame 6 or this connecting member and bending the front side outward. The passage of the bar is narrowed toward the rear.

The upper conveyance device 10 fixes a sprocket (not shown) to an upper extension of the sprocket drive shaft 16 and also extends a pair of upper conveyance cases 20 rearward and upward from a storage posture (solid line in FIG. 2). The parallel link 21 is provided in the right rotation posture (dotted line in FIG. 2) or the opposite side and the left rotation posture.

A transporting endless belt 22 with protrusions made of an elastic material is wound around both sprocket for every 0, and the transporting endless belt 22 with protrusions is stretched.
The protrusions are superposed on each other so that the superposed portions move in the same direction. Therefore, the respective rear end portions of the pair of wave endless belts with protrusions 17 and the front end portions of the transport endless belts with protrusions 22 are overlapped with each other, and the upper part of the stem-leaved portion transferred by the pinching device 9 is surely secured. The upper transfer device 10 is transferred to the rear and transferred to the rear, and is switched to the right rotation posture.
It is gradually discharged from the rear end portion to the collecting and discharging device 11.

The collecting / discharging device 11 is provided with a guide cover 23 formed on the inclined surface with the left and right sides facing outward, below the upper conveying device 10 in the storage position, and the collecting / discharging shutters 24 are switched to the left and right of the guide cover 23 as appropriate. Around the support shaft 25 provided in the standing posture (solid line in FIG. 2), the horizontal collecting posture (dotted line in FIG. 2), and the discharging posture in the hanging state by the operating mechanism (not shown). It is pivoted up and down to support the switch freely. At this time, the attitude change of the collecting / discharging shutter 24 and the change of the left / right rotation of the upper transfer device 10 may be performed individually, but the upper transfer device 10 is rotated left or right from the storage position. When the posture is switched, the collecting and discharging shutter 24 in the same direction is interlocked with this, and when the upper transporting device 10 is returned to the storing posture, the collecting and discharging shutter 24 in the same direction is interlocked with this. May return from the collecting posture to the storing posture. However, the operation of switching the collecting and discharging shutter 24 from the collecting posture to the discharging posture or the operation of returning the collecting and discharging shutter 24 from the collecting posture to the collecting posture is performed by manual operation. As a result, the collecting and discharging shutter 2 in the collecting posture corresponding to the stem-leaved leaves conveyed obliquely backward by the upper conveying device 10.
Collecting and releasing shutter 2 every time a fixed amount is received
4 is switched to the discharging posture and discharged to the ground, and then switched to the collecting posture again, and thereafter, collecting and discharging are repeated in the same manner.

The power of the engine 2 is decelerated in the mission 3 and transmitted to the wheels 4 on both sides via the wheel transmission portion 26, and is also transmitted to the left and right sprocket drive shafts 16 via the sprocket drive transmission portion 27. The pair of wave-protruding endless belts 17 and the pair of projecting conveying endless belts 22 are rotated, and further the sprocket shaft 15 rotated by the pair of wave-protruding endless belts 17 rotates the rotary shaft 12 by the chain transmission mechanism 28. It is driven to rotate the belt 14 with radial projections.

In addition, 29 in the drawing is a pair of grass bodies provided at the frontmost ends on both sides of the machine frame 6, 30 is a sled body arranged slightly behind each grass body 29, and 31 is a front end portion of the pinching device 9 and a ridge top surface.
