Further, the conveyance belt drive shaft 31 is rotated by the rotation of the rack gear 20, and the nipping conveyance belt 24 is driven.

Next, referring to FIG. 4 to FIG.
Will be described. 4 and 5, the ridge pressing mechanism T is provided on the support frame 46 with the left and right roller units 2L and 2L.
R is attached. The support frame 46 is formed in a substantially U-shape in plan view, and the gear case fixing bracket 3 for fixing the rotation center gear case K is disposed behind the support frame 46. 3 is fixed. The right and left traveling frames 19 and 19 are located below the rear end of the support frame 46.
Are connected to each other. Support brackets 51 are provided outside the front end of the support frame 46.
Are fixed, and the upper ends of the support arms 52 are pivotally supported by the support brackets 51 so as to be vertically slidable and rotatable. The left and right roller units 2L and 2R are fixed to the lower ends of the arms 52.

The left and right roller units 2L and 2R are provided with a plurality of substantially drum-shaped rollers 2La and 2Ra, respectively, and are arranged side by side in the front-rear direction. In this embodiment, four left and right rollers 2La. 2Ra is provided. The left and right rollers 2La and 2Ra are formed of an elastic member such as rubber or a sponge-like member, and are rotatably supported by supports 56 and 56 disposed on the left and right of the left and right rollers 2La and 2Ra.

A pair of left and right guide members 58 are provided between the left and right roller units 2L and 2R, and are respectively attached to the left and right roller units 2L and 2R with bolts or the like. The pair of left and right guide members 58, 58 are provided with bar-shaped members facing each other from the front to the rear of the left and right roller units 2L, 2R, and the front ends thereof open substantially outward as going forward. The rear end portion is formed in a substantially "C" shape that opens outward as it goes rearward. In addition, since the mounting hole for mounting the guide body 58 to the left and right roller units 2L and 2R is formed as a long hole having a long diameter in the left and right direction, the mounting position of the guide body 58 to the left and right roller units 2L and 2R is set. Is adjustable left and right.

For example, the potato vines scraped by the scraping devices 14 and 14 are moved by the nip pressing mechanism T
, The potatoes in the soil may rise depending on the size and shape of the potatoes even though the ridges are pressed by the ridge holding mechanism T when the pods are transported to the position shown in FIG. However, as described above, the left and right roller units 2L
By providing the guide bodies 58 between the 2Rs, the upper end portions of the raised potatoes are caught by the guide bodies 58, 58 so that the potatoes cannot be raised any further. Will remain on the furrow. Thus, the guide bodies 58 can prevent the lifted potatoes from being pulled out and conveyed backward. Further, since the guide body 58 is configured so that the mounting position with respect to the left and right roller units 2L and 2R can be adjusted in the left-right direction, the guide body 58 is positioned at an appropriate position according to the ridge shape, the size of the potato, and the like. Or, by attaching the potatoes at intervals, the pulling out of the potato can be reliably prevented.

6 and 7, the support bracket 51 is fixed to the outside of the front end of the support frame 46, and the support arm 52 for supporting the left roller unit 2L is fitted through the support bracket 51 from below. ing. A pin bracket 64 is fixed to the outer surface of the support bracket 51, and a height adjusting pin 63 is slidably attached to the pin bracket 64.

The height adjusting pins 63 are provided with a plurality of vertically extending fixing holes 72 at the upper end of the support arm 52.
, And the support arm 52 is pivotably supported. The height of the left roller unit 2L can be adjusted by changing the positions of the fixing holes 72 into which the height adjusting pins 63 are fitted. The height adjusting pin 63 is urged inward by a spring 65, that is, in a direction in which the height adjusting pin 63 fits into the fixing hole 72, and
It is configured so that it does not fall off. Incidentally, the right roller unit 2R constituting the ridge holding mechanism T is also rotatably supported by a support bracket 51 fixed to the support frame 46, similarly to the above-described left roller unit 2L.

As described above, the left and right roller units 2L
The 2R is rotatably supported by the support bracket 51 via the support arm 52 and the stay 53 at the front portion thereof.
The rear part of R is in a state of being lowered. A support arm 52 that fits inside the support bracket 51
The amount of rotation is regulated by the front side surface 61 of the support bracket 51 located in front of the support arm 52 and the rear side surface 62 located behind. That is, the support arm 52
However, when the support arm 52 rotates around the fixing hole 72 in which the height adjustment pin 63 is fitted, the support arm 52 comes into contact with the front and rear side surfaces 61 and 62 of the support bracket 51. 51 front side 61 and rear side 6
The range is between 2. Thus, the amount of vertical rotation of the left and right roller units 2L and 2R is restricted.

The support brackets 51 support the left and right roller units 2L and 2R in a rotatable manner, and also function as a rotation amount restricting member for the vertical rotation amount of the left and right roller units 2L and 2R. As described above, since the vertical rotation amount of the left and right roller units 2L and 2R is restricted by the support bracket 51, the left and right roller units 2L and 2R are inadvertently rotated excessively and appropriately press the ridge. Not possible, left and right roller units 2L and 2L
It is possible to prevent the tip of R from falling too much and sticking to the ridge.

The left and right roller units 2L and 2R are
As shown in FIGS. 8 and 9 (shown in the right roller unit 2R
Is attached to the stay 53 supported by the support bracket 51 with bolts 75, 75, etc., but the mounting holes 71 of the stay 53 into which the bolts 75, 75 are fitted.
71 is formed in a long hole, and the left and right roller units 2L
The mounting position of the 2R can be adjusted within the range of the long diameter of the mounting holes 71. That is, the left and right mounting positions of the left and right roller units 2L and 2R with respect to the body are the mounting holes 71.
It is configured to be adjustable within the range of the major axis of 71. Thus, the left and right roller units 2L and 2R can be adjusted to the right and left mounting positions to positions corresponding to the shape of the ridge, and the ridges can be pressed by the left and right roller units 2L and 2R in an appropriate state without displacement. Floating and pulling out of potatoes inside can be prevented.

[0030]

As described above, the present invention has the following advantages. That is, since the ridge pressing mechanism configured to be rotatable up and down is provided with the rotation amount regulating body that regulates the vertical rotation amount of the ridge pressing mechanism, the left and right roller units are inadvertently rotated. It was possible to prevent the ridges from being pressed properly and the right and left roller units from falling too far and sticking to the ridges.

Further, since the left and right roller units constituting the ridge pressing mechanism are configured so that the left and right positions with respect to the body can be adjusted, the left and right roller units can be mounted at positions corresponding to the ridge shape. By adjusting the position, the ridges could be pressed by the left and right roller units in an appropriate state without slippage, and the floating and pulling out of potatoes in the soil could be prevented.

Further, the potatoes in the soil may be stalked between the left and right roller units constituting the ridge holding mechanism.
That is, since a guide body that prevents the potatoes from being pulled out together with the vine is attached, the potatoes that have been transported together with the stems and floated are caught by the guide bodies and remain on the ridges, and the lifted potatoes are pulled out and transported backward. Was prevented.

Further, the mounting position of the guide body to the left and right roller units can be adjusted in the left-right direction, so that the guide body can be adjusted in accordance with the ridge shape, the size of the potato, and the like. It can be attached at a suitable position or at an interval, and the pulling out of the potato can be reliably prevented.
