Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pinching belt drive structure of a foliage processing machine.

[Conventional technology]

When harvesting an underground rhizome crop such as a potato, a method of pulling and transporting the stems and leaves while pinching them with a pair of right and left pinching belts that horizontally rotate in a front-rear-back-high manner is disclosed in, for example, JP-A-1-06
Known as No. 3312. By the way, unlike the stems of rice and wheat, the stems and leaves of these rhizome crops are soft and bend greatly to the left and right, so they are formed on the surface unlike the combine belts of binders and binders. The elastic protrusion is a large triangular wave protrusion, and its width is considerably wide.

[Problems to be solved by the device]

By the way, the conventional sandwiching belts are forcibly driven independently of each other (the drive force of one sandwiching belt is connected to the drive portion of the other sandwiching belt by a chain or sprocket). ， The drive structure was complicated, the weight was heavy, and the price was high.

[Means for Solving the Problems] In view of such circumstances, the present invention focuses on the shape unique to the wave protrusion of the sandwiching belt, forcibly drives only one sandwiching belt, and the other sandwiching belt. Is designed to be interlocked by the engagement of the wave protrusions.

[Action]

By adopting this means, even if the other sandwiching belt does not have its own drive structure, it will be linked by the driving force of one of the sandwiching belts.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 2 is a side view of the foliage processing machine, and FIG. 3 is a front view of the same.

The foliage processing machine comprises a traveling vehicle section 1 and a foliage processing section 2 having the following configuration.

The foliage processing section 2 is provided with a scraping device 3 at the frontmost part, and thereafter, a scooping device 4, an upper conveying device 5, a collecting / discharging device 6 and the like are sequentially provided at the rear.

The scraping device 3 includes a pair of left and right scraping drums 8 in which radial elastic projections 7 made of rubber or the like are tilted in a slightly lower front upward direction.
Is rotated synchronously toward the next-side pinching device 4 side. The drive system is such that the power transmitted to the driven side below the pinching device 4 is transmitted to the drum shaft 10 by the chain and sprocket mechanism 9 (independently for each left and right). It is preferable that the turning loci of the left and right radial elastic protrusions 7 are partially overlapped,
Further, the rotation locus is always overlapped with the pinching opening 11 at the starting end of the pinching device 4. The scraping device 3 forms a ridge 12 and a foliage portion 13a of a rhizome 13 planted in the ridge 12.
This is for scraping (for leaving the collected root portion 13b in the soil as it is) to the next pinching device 4.

The pinching device 4 is provided behind the scraping device 3 with the lower end as a starting end, and the lower support shafts 14a, 14b and the upper support shafts 15a, 15b are erected in a front low rear high relationship. A pair of left and right bearings are provided, and each of these lower support shafts 14a, 14b and upper support shaft 15
Wave protrusions 16 made of elastic material such as rubber on a and 15b
The sandwiching belt 17 provided with is stretched so as to be rotatable in the front low rear high plane. In this case, the crests and troughs of the left and right wave protrusions 16 mesh with each other in an interlocking manner, and the wavy protrusions 16 are rotated in this state. By the way, the pinch belt 17 in this case
One of the lower support shafts 14a, 14b and the upper support shafts 15a, 15b of one of the upper support shafts 15a, 15b, for example, 15a, guides the power of the prime mover to forcibly drive, but does not connect the other power. . By doing this, one of the pinching belts 17 is naturally driven, but
The other sandwiching belt 17 is also driven by the meshing force between the wave protrusions 16. Therefore, both upper and lower support shafts 14b and 15b of the pinching belt 17 on the side that is not forcibly driven may be idle shafts. In addition, this pinching device 4 is used for the foliage portion 13a of the underground rhizome crop 13.
Only the stem is removed and delivered to the next upper transfer device 5,
The sampling root 13b at this time must be left in the ridge 12 (although most of it is kept in the soil due to the resistance of the soil, etc.), but in order to do this more completely, it is located below the tip of the pinching device 4 At the rear end, a root drop guide bar 19 composed of two bars 19a having a narrowed frontward expansion and having a width that cannot pass the sampling root 13b is installed.

The upper conveying device 5 has two sprockets (not shown) extending from the upper end of each extension of the upper support shaft 15a that is forcibly driven (the support shaft 15b that is located above the pinching belt 17 on the side that is not forcibly driven) to the rear upper part. And a conveyor belt 21 with elastic protrusions 20 is stretched between the upper and lower sprockets. It should be noted that these conveying belts 21 face each other at appropriate intervals and are provided in a pair on the left and right, and the front, rear, rear, and high gradients thereof also correspond to the sandwiching belt 17. By the way, the conveyor belt 21 can be swayed to the left and right within the obliquely inclined plane about the upper support shafts 15a and 15b of the pinching belt 17.

FIG. 1 is a plan view of the part and FIG. 4 shows the details thereof in the same side view. In short, the action shaft 23 is extended downward from the back surface of the transport case 22 accommodating the transport belt 21. Upper support shaft 15a,
An arm 25 rotatably fitted around a sleeve 24 accommodating 15b is connected. A link 27 linked to a switching lever 26 for operating swinging to the left and right is integrated with the arm 25, so that when the switching lever 26 is rotated in a substantially horizontal plane, the arm 25 and the action shaft 23 are sleeved. Rotate around 24. The action shaft 23 is provided with the left and right transport cases 22 respectively. Since these action shafts 23 are connected by the connecting link 28, both the transport cases 22 can be moved by simply moving one arm 25 or the like. It moves together. The upper transporting device 5 has a function of inheriting the foliage portion 13a sent by the pinching device 4, further transporting the foliage portion 13a rearward and upward, and delivering it to the next collecting and discharging device 6.

The collecting / discharging device 6 is composed of a substrate 29 stretched near the terminal end of the upper transport device 5 with a slightly upwardly inclined surface, and a collecting plate 31 connected to the left and right sides of the substrate 29 by support shafts 30 in a wing shape. Become. Further, the collecting plate 31 can take up each of the postures of standing, falling down, and turning by the rotation of the support shaft 30 (it always takes a standing posture).

FIG. 5 is a plan view of the portion showing the case where the conveyor belt 21 is swung to the right, FIG. 6 is a side view of the same, and FIG.
FIG. 9 is a plan view of the portion showing the case where the neutral position is neutral, and the switching of the posture is interlocked with the movement of the switching lever 26 described above.
That is, the working shaft 23 and the drive shaft 15 of the above-mentioned upper transfer device 5
The arms 32 that are also rotatably fitted to the sleeves 24 are provided on the arms 25 that connect the sleeves 24 at the left and right positions similarly to the above-described arms 25. I hang it so that it goes through the outside of 25. The left and right arms 32 and the support shafts 30 that support the left and right collecting plates 31 are connected to each other via a link mechanism 34, and springs 35 are stretched between the bars 33 so that the bars 33 extend inward. Have been punished by. Further, a moving stopper 36 and a fixed stopper 37 are provided between the arm 32 and the sleeve 24, respectively. The arm 32 can rotate outward from the machine centerline direction, but inside the both stoppers 36,
The 37 is regulated so that it cannot rotate (see Fig. 5). Therefore, only the arm 32 on the side where the arm 25 for swinging the conveyor belt 21 rotates is rotated in the same direction to lay down the collecting plate 31 in the horizontal direction, and the collecting plate 31 on the other side is kept upright. is there. Then, when a certain amount of the foliage portion 13a is collected on the collecting plate 31, the spring 35 is extended by its weight and rotated downward to release the foliage portion 13a. Although not shown, the downward rotation of the collecting plate 31 is restricted by a lock pin, and when the worker removes the lock pin at an appropriate timing, the collecting plate 31 is forcibly moved downward by power. It is also conceivable to rotate it. Even when the collecting plate 31 is laid down in the horizontal direction, if the collecting plate 31 is raised by hand, the link mechanism 34 and the arm 32 are operated in reverse to collect the collecting plate 31.
Since the 31 can be easily erected, this operation may be performed when there is an unextracted foliage portion 13a in the vicinity, or when the vehicle is running on the road.

In addition, a divider 38 for branching is provided on the front side of the scraping device 3, and a sled body 39 for stabilizing the machine body is provided behind it. Further, a gauge wheel 40 for setting the ground height of the pinching devices 4 is provided below the pinching devices 4. Furthermore, the traveling vehicle unit 1 has an engine 4
1, mission 42, steering wheel 43, wheels 44, etc. are provided respectively.

[Effect of device]

As described above, the present invention is the one described above, that is, only one of the sandwiching belts 17 is forcibly driven, and the other sandwiching belt 17 is interlocked by the engagement of the wave projections 16 with each other. Therefore, even with this shape, which is peculiar to the large triangular wave protrusion 16, the wave can be rotated smoothly. Therefore, a power transmission structure from one side of the sandwiching belt 17 to the other side of the sandwiching belt 17 becomes unnecessary, and the weight and cost can be reduced.

Further, as a result of this, the wave protrusions 16 are strongly pressed against each other, so that the pinching force for grasping the foliage portion 13a becomes strong and the wave protrusions 16 do not fall off. Of course, since the wave protrusion 16 is made of a soft elastic material such as rubber, the pinching force does not become excessive, and it is not cut into pieces.
