After the vine or the like passes through the front upper holding conveyance path k2, the lower holding conveyance path k1 and the rear upper holding conveyance path k3 continue to be nipped and conveyed in a rearward upward inclined manner.
[0050]
During this conveyance, especially, a piece of vine vine sticks to each lower pinch conveyance belt 47, but the scraper 48 drops the piece (eg, forward of the engine 1). At this time, the scraper 48 is inclined obliquely forward and downward with respect to the moving direction of each nipping and conveying belt 47, and the scraping process is smooth and accurate.
[0051]
When the rear portion of the nipping / conveying device 31 is swung to the left and right, the grip 44 is held, so that the left and right arm members 39 and 39 swing around the drive shafts 17 and 17 and the right and left biasing force is applied. The rod bodies 42 and 42 swing around the support shafts 41 and 41. Therefore, the holding and conveying device 31 is bent in the middle thereof, and the rear portion thereof is inclined as shown in FIG. 7, for example. The bending angle of the holding and conveying device 31 at this time is alternatively set to a plurality of arbitrary sizes via an appropriate locking mechanism (not shown).
[0052]
Further, as shown in FIGS. 1, 2 and 5, the following characteristic configuration is formed in relation to the holding and conveying apparatus 31.
[0053]
That is, the vertical support shafts 69 and 69 are fixed to the center of the pulleys 65 and 65 on the front upper surfaces of the rear frames 68 and 68 on the left and right sides, and the guide roller 70 is attached to each of the vertical support shafts 69 and 69. 70 are rotatably mounted.
[0054]
At this time, the guide roller 70 is rotated lightly via a ball bearing (not shown), and the mass is made as small as possible. For this reason, the peripheral surface portion of the guide roller 70 is formed of a vinyl chloride pipe or the like, and the inside thereof is a space.
[0055]
It is preferable that the guide roller 70 has no dent in the upper end surface portion, and in this way, no dirt or the like is accumulated on the upper end surface portion. The guide roller 70 has a diameter of, for example, about 10 cm to 25 cm, and a height of, for example, about 5 cm to 30 cm, and is preferably related to the size of the nipping and conveying device. A diameter and height equal to or greater than half width.
[0056]
Next, a usage example and operation of the foliage processing machine configured as described above will be described with reference to FIGS.
FIG. 8 is a diagram showing the operating state of the front part of the processor, and FIG. 9 is a diagram showing the operating state of the main part of the processor.
[0057]
In a field where sweet potatoes are planted in a row on a ridge (high ridge or flat ridge), the aircraft is positioned so that the left and right traveling wheels 5 and 5 straddle one ridge, and if necessary, weed cutting The heights of the gage wheels 10 and 10 are adjusted so that the height of the part D is optimal, and the heights of the left and right heel presser roller units 11a and 11b are adjusted so that the heel presser mechanism B fits the upper surface of the heel. The width is adjusted, and the rotation operation handle 20 is further operated to swing the foliage conveyance processing portion E around the fulcrum O so that the front portion thereof is adapted to the upper surface of the ridge.
[0058]
Thereafter, the engine 1 is operated, and the body is moved forward with each part in an operating state. As a result, the weed cutting section D, as shown in FIG. 8, weeds the vines and the like that grew and rooted in the right and left grooves m of the heel h, cuts them up, cuts them, and guides them to the scrambling section x of the scoring device 30A. .
[0059]
The scraping device 30A collects the vines prospered between the left and right cutting devices 21 and 21 by the scraping portion x and moves them into its own transport path, that is, the upper transport path k2 on the front side, and at the same time the lower clamp It is supplied to the front part of the conveyance path k1.
[0060]
The upper transport path k2 and the lower transport path k1 on the front side sandwich and transport the vines that are moved or supplied in this way in the backward upward tilt direction. At this time, the vine is moved in a bulky state that is greatly raised above the upper conveyance path k2, but is sandwiched between the upper and lower parts by the upper conveyance path k2 and the lower conveyance path k1, and on the upper surface of the stiffening frame 63. Since it is supported, it is transported stably.
[0061]
During this transport, the lower transport path k1 sandwiches the vine with a particularly strong force and moves it upward, so that a strong lifting force is applied to the stem of the vine eventually and the stem is torn off and separated from the heel. The Instead of such tearing, cutting with an appropriate cutting blade may be performed, but tearing is superior in that it does not damage the heel.
[0062]
The release position of the vine that has been separated in this way and is in a free state is determined by the left and right positions of the rear end portion of the nipping and conveying apparatus 31. For example, the holding and conveying device 31 is held in a straight line in the front-rear direction when discharging onto the bag being processed, and the holding and holding device 31 is held by holding the handle 44 when discharging to the left and right positions away from the bag. The rear part is swung to the left and right, and the lower holding conveyance path k1 and the upper holding conveyance paths k2, k3 are held in a state bent at an appropriate angle.
[0063]
In this usage example, a case will be described in which the nipping and conveying apparatus 31 is largely folded to either the left or right side, and the vine is released to a position as far as possible from the cocoon being processed.
[0064]
The vine that is being transported in the lower transport path K1 and the upper transport path k2 on the front side is torn and freed, and then reaches the folding position p of the pinch transport device 31. At this position, the vine grows due to this folding. The transport resistance tends to increase, and the force in the direction intersecting the sandwiching transport path acts on the vine at the bent position p due to the gravity action, and these vines tend to be biased downward in the horizontal direction. The device 31 may spill laterally from the top surface.
[0065]
However, the guide roller 70 that exists in the vicinity of the bent position p supports and smoothly guides the vines exhibiting the above-described tendency at the bent position p. At this time, when the nipping / conveying device 31 is folded to the right as shown in FIG. 9, the right guiding roller 70 effectively prevents spilling of the vine in the arrow direction f1, and conversely, the nipping / conveying device 31 is left-sided. In particular, the left guide roller 70 effectively prevents spilling of the vine in a direction symmetrical to the arrow direction f1. As a result, the vines can pass through the bent position stably without any trouble.
[0066]
Thereafter, the lower transport path k1 and the rear upper transport path k3 transport the vines to the transport end and drop them.
As a result, the vines are efficiently and accurately removed in units of vines, and the sweet potato can be harvested labor-saving.
[0067]
