Preferably, the left and right guide rods 25b are formed in a C-shape in plan view of the squeezed portion x. It is located on the extension of each of the left and right leading edges.

At this time, the front portion of the lifting guide bar 25b has a portion h1 which is raised at a relatively large angle from the front end thereof, and a horizontal portion or a portion h2 which is raised at a relatively small angle. And

The outer guide rod 2 is formed by projecting upward from the distal end of the projecting rod 25a in a slightly outward direction.
5c is provided. In addition, a vertical guide roller 23b is axially mounted on the outer surface of the outer portion 23a of the main body frame 23 of each cutting device 21 at the front end. At this time, the guide roller 23
The front edge of b is aligned with the front edge of the outer portion 23a in the front-rear direction, or is positioned forward of the front edge of the outer portion 23a.

Next, examples of use and operation of the foliage processing machine according to the present invention configured as described above will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 9 is a front view of a front portion of the processing machine.

In a field where sweet potatoes are planted in rows on a ridge (high ridge or flat ridge), the machine is positioned so that the left and right traveling wheels 5, 5 straddle one ridge U. As a result, the left and right weed cutting sections D are located in the left and right ridge grooves m, m as shown in FIGS. If necessary, the height of the gage wheels 10, 10 is adjusted so that the height of the weed cutting section D is optimal, and the left and right ridges are adjusted so that the ridge holding mechanism B conforms to the upper surface of the ridge U. Pressing roller units 11a, 11b
The height and width of the ridges U are adjusted, and the rotating operation handle 20 is further operated to swing the foliage transport processing unit E around the fulcrum O, so that the front part thereof is adapted to the upper surface of the ridge U.

After that, the engine 1 is operated, and each part is operated to advance the body. As a result, the projecting rods 25a of the dividers 25, 25 have the potato vine w rooted in the ridge m.
From the ground, and then lift guide rods 25b, 2
5b lifts gradually higher. Thereafter, the lifting guide rod 25b, the protruding rod 25a, and the digging plate 24 pull out the floating potato vine w while guiding it backward, and guide it to the cutting blade 22 and the scraping portion x of the cutting device 21.

Here, the relationship between the lifting guide rod 25b and the ridge U or the scraped portion x will be described as follows. That is, the front portion of the lifting guide rod 25b is directed rearward from the front end thereof at a relatively small included angle θ in the front-rear direction f1 in the front-rear direction f1, and relatively large from the front end of the guide rod 25b rearward. Since the guide rod 25b is raised at an angle, the guide rod 25b is less likely to come into contact with the ridge shoulder than when the guide rod 25b is straight.

The rear portion of the lifting guide bar 25b is bent inward and is directed obliquely rearward at a relatively large included angle θ1 in a plan view with respect to the front-rear direction f1, and the rear end of the rear end is positioned on the corresponding side. Is closer to the outer side of the raked portion p1 than in the case where the guide rod 25b is a straight line, and is in a state more accurately along the upper surface of the ridge U, and the rear end of this is near the front of the raked portion x. Can be appropriately positioned.

At this time, the formation of the horizontal portion or the portion h2 rising at a relatively small angle in the lifting guide bar 25b sets the inclination of the front side portion of the guide bar 25b appropriately within a wide angle range. It is possible to specify the shape of the guide rod 25b along the ridge surface.

Under such a relationship, the lifting guide rod 25b is particularly connected to the ridge shoulder or ridge groove m between the cutting devices 21, 21.
The potato vine w is guided accurately and smoothly to the cutting devices 21 and 21 and the outer portion p1 of the scraping portion x. Further, the fact that the left and right guide rods 25b are positioned on the extension lines of the left and right front edges of the scraping portion x in a C-shape in plan view means that the potato vine w guided by these guide rods 25b is swept into the scraping portion x. Is moved in the direction of the scraping, and the scraping by the scraping portion x is further smoothed.

The outer guide bar 25c guides the potato vine w guided by the lifting guide bar 25b backward together with the guide bar 25b, and moves the potato vine w in a direction convenient for the cutting process of the cutting device 21. Hold at height.

The potato vine w that has reached the cutting blade 22 of each cutting device 21 is cut and separated inside and outside between the cutting devices 21. At this time, the guide roller 23b makes this separation smooth and prevents the vine w from getting caught on the corner of the front edge of the cutting device 21. Then, the potato vines w present inside the space between the cutting devices 21 and 21 are guided by the lifting guide rod 25b and smoothly moved to the raking unit x.

The scraping portion x collects the potato vine w overgrown on the ridge surface between the left and right cutting devices 21 and 21 and the potato vine w guided by the guide rod 25b to the center, and conveys its own transport path, that is, the front side. It is moved into the upper transport path k2, and at the same time, is supplied to the front of the lower nipping transport path k1.

The upper transport path k2 and the lower transport path k1 on the front side pinch and transport the thus-moved or supplied potato vine w in the upward and downward inclined direction. At this time, the potato vine w is moved in a bulky state that is greatly raised above the upper transport path k2. However, the upper transport path k2 and the lower transport path k1 sandwich the upper and lower two places. , And can be stably conveyed.

During this transport, the lower transport route k1 sandwiches the potato vine w with a particularly strong force and moves it upward, so that a strong pulling force is eventually applied to the stem of the potato vine w. It is torn off and separated from the potato section.

The release position of the separated potato vine w which is in a free state is determined by the left and right positions of the rear end of the nipping and conveying device 31. For example, when discharging onto the ridge U during processing, the holding and conveying device 31 is held in a straight line in the front-rear direction, and when discharging to the left and right positions away from the ridge U, the holding and conveying device 31 is held with a handle 44. 31 is swung right and left to lower and lower nipping transport path k1 and upper nipping and transport path k
2. Keep k3 bent at an appropriate angle.

The potato vine w in the free state, which is being conveyed on the lower holding and conveying path K1 and the upper conveying path k2 on the front side, reaches the bending position p of the holding and conveying device 31 in due course. Since the upper part of the potato vine w which has reached this position is smoothly guided by the guide roller 70, the potato vine w can stably pass this bent position without any trouble.

After that, the lower holding transport path k1 and the rear upper transport path k3 transport the potato vine w to the transport end and drop it. As a result, the potato vine w is efficiently and accurately removed in units of ridges, so that the sweet potato can be harvested labor-saving.

Next, the characteristic structure of the vine processing machine according to the second invention will be described with reference to FIGS. The figure is 10

The guide rod 25b for lifting is formed in a straight line, and at this time, the rear end of the guide rod 25b is brought as close as possible to the outside point p1 of the raking portion x. Further, a triangular additional plate 25d indicated by oblique parallel lines may be provided between the protruding rod 25a and the lifting guide rod 25b.

Each of the dividers 25 is capable of swinging around the protruding rod 25a, and is specifically configured as follows. That is, the rear part of the projecting rod 25a is
Is inserted into a bearing 24a fixed to the shaft, and the protruding rod 25a can swing around its rear part. At this time, the protruding rod 25a is made to face the cutting blade 22 in front of the cutting blade 22 as shown by a virtual line KL in FIG.

An arm member 71 is fixed to the rear end of the protruding rod 25a, and the arm member 71 and the cutting operation lever for the cutting device 21 on the side associated with the arm member 71 are operatively connected to each other. A spring (not shown) for urging the protruding rod 25a toward the directly facing position is engaged with the protruding rod 25a. When the cutting operation lever is operated to the operating side of the cutting device 21, the lifting guide rod 25b is moved by the spring. When the cutting operation lever is operated to the non-operating side of the cutting device 21, the lifting guide rod 25b is held at the directly facing position. It is configured so that:

Next, an example of use of the above-mentioned vine processing machine and its operation will be described. The airframe is positioned on the ridge U in the same manner as in the previous embodiment. Then, when none of the potato vines on the ridges adjacent to the left and right is unprocessed, the left and right cutting operation levers are operated to set the respective cutting devices 21 and 21 in the operating state.

As a result, both the left and right dividers 25, 25 are held in their proper positions, and the potato vines in the left and right ridge grooves m, m and on the ridge shoulders are lifted and guided to the cutting devices 21, 21 and the scraping portion x. Then, the cutting devices 21 cut the potato vines located in the left and right ridges m, m. Thereafter, the potato vines are processed according to the previous embodiment.

On the other hand, when the potato vine of any of the ridges adjacent to the left and right of the ridge being processed has already been processed, the cutting operation lever on the processed side is kept in the cut state, and the cutting on that side is performed. The device 21 is not operated, and only the cutting operation lever on the unprocessed side is turned on to operate only the cutting device 21 on that side.

As a result, the divider 25 on the unprocessed side is held in the normal position and operates as described above. However, the divider 25 on the processed side has the cutting edge 2 of the cutting device 21 on that side.
It is held in a state of facing directly to 2.

Therefore, the divider 25 on the processed side gradually lifts the potato vines scattered in the already processed ridge groove m by the protruding rod 25a and the lifting guide rod 25b while the machine body is in progress, and the scraps of the potato vines are removed. Before reaching the cutting blade 22 on this side, they are moved so as to be distributed to the left and right. This sorting movement is also assisted by the guide roller 23b. Therefore, it is possible to avoid that the potato vines are stuck on the leading edge of the inoperative cutting device 21 and accumulated.

The protruding rod 25a and the lifting guide rod 25b
When a triangular additional plate 25d is provided therebetween, a piece of potato vine or the like is not embraced here. Note that, depending on the processing conditions, the guide rods 25b of the left and right dividers 25, 25 may be used in a state of facing the cutting blade 22.
