The foliage processing machine of the present embodiment is constructed as described above. Next, an example of use and operation when processing the foliage of potatoes planted on the ridge U will be described.

As shown in FIG. 5, the traveling body 1 is positioned such that the left and right traveling wheels 15, 15 straddle the ridge U covered with the multi-film f. At this time, the front body frame 12
The left and right end portions 12a of the left and right sides of the ridge U are located at approximately the center of the width of the left and right ridge grooves n, and the left and right running wheels 15, 15 are respectively located near the left and right ridge base points p, p of the ridge U. Is positioned.

The ridge U is generally produced by a ridge forming machine equipped with a molding die. Therefore, the distances p, p between the left and right ridge base points are fixed dimensions, that is, 500 mm or 600 mm.
mm. Therefore, the left and right traveling wheels 15, 1
The distance between 5 is also about 500 mm or 600 mm so as to match the ridge U.

Further, the collecting plate 7b is swung downward so that one of the right and left collecting plates 7b is in a horizontal posture. At this time, the rear device frames 29, 29 are moved toward the side of the collecting plate 7b swung down as necessary. Swing by an appropriate angle. Thus, the nipping and conveying device 4 is bent near the upper portion of the support cylinder 27.

By adjusting the height of the scraping device 3 supported by the support members a and b, the scraping direction in the side view is made to be more than that in the side view of the nipping and transporting device 4 as shown in FIG. 6A. The angle is steeply inclined by the angle α. The degree of the steep inclination is determined so that the relative height h between the upper surface m of the ridge and the tip end of the nipping and conveying device 4 is sufficiently ensured. After that, the steering handle 13 is held, and each part is brought into an operating state.

In this operating state, the rotation of the engine 9 is transmitted to the traveling wheels 15, 15 to advance the traveling body 1, while being transmitted into the intermediate transmission case 11 to rotate the rotation output shaft 3.
2. Rotate 32. The rotation of the rotation output shafts 32, 32 is transmitted through the chain transmissions 34, 34 to the driving guide wheels 30,
30 is rotated, and the driving guide wheels 30, 30 rotate the holding conveyance belts 35, 35 to the front guide wheel 21 and the intermediate guide wheel 3.
Rotate around 1a, 31b, 31c.

At this time, the front guide wheel 21 is rotated in conjunction with the nipping and conveying belts 35, 35, and this rotation is
a, the driving guide wheel 2 via the universal joint 22c
3 and 23 are rotated, and the scraping belts 25 and 25 are rotated in the scraping direction.

While the traveling machine 1 is in progress, the weeding section 2 separates the planted foliage w of the ridge U to be treated and the planted foliage w of the ridge adjacent to the ridge U, and As shown in FIG. 4, the hourglass rings 6b of the parts 6, 6 are brought into contact with the left and right shoulders of the ridge U to maintain the height of the front part of the fuselage constant. The rods 5 and 5 are in the state of being located on the left and right sides of the stem of the planted foliage w close to the upper surface of the ridge U,
The rear drum-shaped ring 36 is in a state where the upper surface of the ridge U is pressed with an appropriate force.

At this time, the arc-shaped peripheral surfaces of the hourglass-shaped rings 6b and 36 are more along the ridge than when they are flat, so that the width of the ridge is uniformly pressed.

The raking device 3 uses the raking projection 25a to
The planted foliage w planted on the ridge upper surface m is raked and sent to the conveyance start point of the nipping and conveying device 4, and the nipping and conveying device 4 pinches the planted foliage w thus fed, and The sheet is conveyed diagonally upward at a speed synchronized with the traveling speed of No. 1.

By this transport, the planted foliage w is gradually pulled up greatly, and when the pulling force exceeds the pulling strength of the foliage w, the foliage w is pulled out to the ground leaving its root. At this time, the potatoes at the root tend to come out together with the stems and leaves w, but the hourglass rings 6b, 6b uniformly press the upper left and right surfaces of the root to regulate the roots.

When the foliage w is lifted up, the multi-film f tends to be lifted. However, since the left and right running wheels 15, 15 step on the multi-film f above the ridge bases p, p. Multi film f is ridge U
Is pulled to the left and right sides to be in a state of being in close contact with the ridge surface, and when the foliage w is lifted up, its lifting is regulated. Therefore, during the processing of the foliage w
The situation where the multi-film f is involved is effectively avoided.

On the other hand, the roots of the planted stems and leaves w may not be able to withstand the pulling force of the nipping and conveying device 4 and may be pulled out together with the stems and leaves w. The locking guide rods 5 lock the rising of the root portion beyond a certain level. As a result, the foliage w is forcibly separated from the root thereof and is continuously transported by the nipping transport device 4, and the separated root remains in the ground.

Although many foliage parts w are processed without any trouble, the foliage part w and its root are not separated at the place where the pair of locking guide rods 5 and 5 are present, and pass through this place. After that, the root may be pulled out.

In such a case, the hourglass ring 36 immediately presses the ground surface on the rear upper portion of the root portion being pulled out to prevent the root portion from coming off, whereby the foliage w is removed from the root portion. Are torn apart. Also in this case, the lifting of the multi-film f is restricted by the left and right traveling wheels 15 and 15 in the same manner as described above, and the situation in which the nipping and conveying device 4 involves the multi-film f is avoided. When a strong rearward force acts on the hourglass ring 36, the hourglass ring 36 swings and retracts rearward against the elasticity of the spring 38, thereby avoiding damage. Such swing retreat is necessary also when the height of the ridge upper surface m fluctuates, in order to adapt to the fluctuation and maintain the functions of the respective parts satisfactorily.

In this manner, the foliage w is reliably separated from the root thereof, conveyed by the nipping and conveying device 4, and dropped on the substrate 7a and the upper surface of the collection plate 7b in the horizontal posture in a rearwardly falling posture with the tip of the stem rearward. Because

In the above operation, even if the ridge upper surface m is in a state where there is some height, the tip of the nipping and conveying device 4 is swept with the conveying direction in side view of the nipping and conveying device 4 as shown in FIG. 6B. Since the relative height h with respect to the ridge upper surface m is held sufficiently large as compared with the conventional case where the transport direction in the side view of the device 3 is matched, the left and right sandwiching transport belts 35, 35 bite the soil, Further, the multi-film f covered with the ridge surface is in a state where it is harder to be caught.

The dimension between the front end portions of the right and left sides of the front body frame 12 is located within the width of the ridge grooves n formed on the left and right sides of the ridge U. Foliage w
During the processing, the front body frame 12 and the weeding section 2 attached to the front body frame 12 contribute to preventing the smooth processing from being hindered by contact with the multi-film f.

Further, an outer peripheral wheel member 15b of each traveling wheel 15
Is covered with the cover plate 151 to prevent the untreated foliage w and the multi-film f of the adjacent strip from getting entangled with the radius member 15c of the traveling wheel 15 during the processing of the foliage w.

[0051]

According to the present invention described above, since the distance between the front end portions on the right and left sides of the front body frame is located within the width of the ridge grooves formed on the left and right sides of one ridge, During processing, the front end of the front body frame is less likely to come into contact with the ridge, so that the multi-film covered with the ridge surface will not be caught, and the left and right traveling wheels will move the multi-film covered with the ridge surface on each side. As a result, the multi-film comes into close contact with the ridge surface, so that the occurrence of a situation in which the sandwiching and conveying device involves the multi-film is effectively prevented, and a smooth foliage treatment can be performed.

According to the second aspect of the present invention, since the inside of the outer peripheral wheel member of each traveling wheel is covered with the cover plate, the ridged multi-film or the adjacent strip is not covered during the processing of the foliage. The processed foliage and the like are unlikely to be entangled with the radius member of the traveling wheel.

According to the third aspect of the present invention, the positions of the traveling wheels on each of the left and right sides can be changed to any one of at least four locations every several centimeters in the lateral direction of the machine body. In contrast, the left and right running wheels can reliably pull the ridge-covered multi-film to the left and right sides, and if necessary, the left and right running wheels are positioned at the approximate center of the width of the ridge groove and run. It can be made to be.
