【Example】

 First, a conventional foliage processing machine will be described. As shown in FIGS. 3 and 4, this foliage treatment machine is a device for scraping the foliage of an underground crop to the rear, and a rake for scraping the foliage scraped by the scraping device (8). And a rearing device (9) for transferring the stems to the rear side, and an upper conveying device (10) for conveying the leaf removal portion, which has been stem-transferred by the grasping device (9), toward the fuselage one side behind the inherited skew. And a collecting / discharging device (11) that collects and discharges a fixed amount of stem-leaved leaves discharged from the rear end of the upper transporting device (11), and a machine frame (6) capable of traveling. ) It is located on the upper and lower slopes. The leaf stalk processing machine as described above is a traveling unit mainly including an engine (2), a mission (3), wheels (4), a handle (5), etc. as shown in FIGS. 3 and 4. (1) is provided at the rear of the machine frame (6), and the foliage processing section (7) is provided on the machine frame (6) in front of the running section (1). The foliage processing part (7) is provided with a scraping device (8), a pinching device (9), an upper conveying device (10), a collecting and discharging device (11), etc. in order from the front to the rear, and , Are formed by obliquely arranging them in a front-rear-rear-high inclined manner. The scraping device (8) is composed of a pair of wrapping and fixing a radial scraping projection belt (14) made of an elastic material around the outer periphery of the rotating body (13) attached to the rotating shaft (12). The rotating shaft (12) is supported by the front end machine frame (6) or this connecting member so as to be located on both sides of the front end of the processing section (7), and the front end rotation locus of the belt (14) with the protrusion for scraping is also supported. It is configured such that the loci of the tips rotate upwards after being viewed from the side, as they overlap each other. As a result, the belt (14) with protrusions for scraping abuts on the foliage of the rhizome crop and can be forcibly guided toward the pinching device (9) at the rear. The pinching device (9) supports a pair of sprocket shafts (15) on both sides and a sprocket drive shaft (16) in front of and behind the machine frame (6) or this connecting member, and a pair of wave protrusions made of an elastic material. A pair of endless belts (17) with wave protrusions are wound around the sprocket shaft (15) and the sprocket drive shaft (16) via the sprocket (18). The projections are configured to mesh with each other at adjacent portions so that the meshing portions advance in the same direction, and the front end of the waveless endless belt (17) is positioned below the rear part of the sweeping side protruding belt (14). The rear end is located at the upper rear, and is slanted so as to have a front low rear high slope. As a result, at the front ends of the meshing portions of the pair of endless belts with wave protrusions (17), the roots of the stems and leaves of the subterranean crops that are scraped by the scraping device (8) are securely clamped, and the rear upper part is secured. As the roots are left on the ground side, the foliage is pulled out upwards and the roots and foliage are transferred rearward and upward. From this rear end, the upper transfer device (10) is transferred. Will be passed on to. The upper transfer device (10) fixes a sprocket (not shown) to the extended upper end of the sprocket drive shaft (16), and stores a pair of upper transfer cases (20) rearward and upward. From the (solid line in FIG. 4) to the right rotation posture (two-dot chain line in FIG. 4) or the left rotation posture on the opposite side, the rotation can be freely switched around the sprocket drive shaft (16) via the parallel link (21). A sprocket (not shown) is rotatably supported at the rear end of the upper transfer case (20), and an endless transfer belt with protrusions made of elastic material is provided between both sprockets of each upper transfer case (20). 22) is wound around and the projections of the pair of endless conveyor belts (22) with protrusions are superposed on each other at adjacent portions so that the superposed portions move in the same direction. Therefore, the rear ends of the pair of wave-protruding endless belts (17) and the front end of the protrusion-carrying endless belt (22) are polymerized, and are transferred by the pinching device (9). The foliage is surely transferred to the rear of the transfer, and is gradually discharged to the collecting and discharging device (11) from the rear end of the upper transfer device (10) switched to the right rotation posture. The collecting / discharging device (11) is provided below the upper conveying device (10) in the storage position with guide guides (23) formed on the inclined surfaces with both left and right sides facing outward, and on the left and right of the guide cover (23). The collecting / discharging shutter (24) is appropriately adjusted by a posture switching operation mechanism (not shown) to store in a standing state (solid line in FIG. 4), in a horizontal collecting posture (two-dot chain line in FIG. 4), and in a hanging posture in a front-back direction. It is supported so that it can be switched by rotating it up and down around the spindle (25). As a result, the collecting and discharging shutter (24) in the corresponding collecting posture receives the stem-leaved portion conveyed obliquely rearward by the upper conveying device (10), and the collecting and discharging shutter (24) is hung down every time a fixed amount is collected. Then, it is discharged to the ground and switched to the collecting attitude again. Then, collecting and discharging can be repeated in the same manner. In FIGS. 3 and 4, (29) is a pair of grass bodies provided at the foremost end on both sides of the machine frame 6, (30) is a sled body arranged slightly behind each grass body (29), (31) Is a compression roller provided so that the vertical position can be adjusted in order to appropriately maintain the distance between the front end of the pinching device (9) and the upper surface of the ridge, and (32) is a protective cover.

According to the above-mentioned foliage processing machine, when the stem of a rhizome crop such as potato is grasped and pulled out, there is a squeeze roll (31) so that the rhizome crop does not rise up. The compression roller (31) is fixedly operated after the height is adjusted by a tool. Then, depending on the condition of the passage of the wheel (4), the left and right height of the wheel may deviate. Therefore, the crushing roller (31) may force the ridges to push out the rhizome crops and damage the rhizome crops. There is. This plan improves this.

As shown in FIG. 1, the compression roller (33) has a drum shape and is rotatably supported by a U-shaped frame (34), and a bearing body (35) of a universal joint is provided on the frame (34). , The spherical head (36) of the universal joint engages with the spherical pair, and the large diameter cylinder (40) of the shaft (37) of the universal joint is fitted into the shaft hole (39) of the support (38). The stopper plate (41) closes the shaft hole (39), and a spring (42) is wound around the shaft between the stopper plate (41) and the bearing body (35). The support (38) is attached to the bar (43) of the machine casing (6).

Since the support structure of the compression roller is configured as described above, the compression roller (33) can swing left and right around the spherical head (36) of the universal joint, and the shaft (37) can rotate. Therefore, the compression roller is a movable type attachment, and since the large diameter cylinder (40) is slidably fitted in the shaft hole (39), the spring (42) is attached to the shaft (37). ) And the compression roller is independent of left and right, and is automatically adjusted up and down. Therefore, the compression roller (33) can move freely against the deviation of the left and right heights of the wheels. This prevents the ridges from being pressed down, so that the ridges will not be pressed more than necessary and the rhizomes will not pop out. Since it is not pressed, it does not resist the progress of the foliage processing machine. Therefore, rhizome crops can be worked without damage.

[0010]

[Effect of device]

 According to the present proposal, since the compression roller is movably supported by the machine frame so that it can be automatically adjusted, the compression roller can change its posture with respect to the displacement of the left and right heights of the wheels. Therefore, the ridges are not pressed unnecessarily, which prevents the subterranean crops from popping out and the pressure roller not forcibly pressing the ridges. Has a feature that it can work without damaging the rhizome crop because it does not force the ridges.
