The onion 27 being conveyed is given resistance by the convex part 34 of the conveyance control member 32, and at this time, the convex part 34 is shifted in phase as shown by the symbol L from the distance 23 between the main roller 20 and the feed roller 21. Since the onion 2 received by the convex portion 34
7 is rotated and is surely introduced into the roller gap 23, and this introduction is done so that the recess 35 corresponds to the roller gap 23 and the protrusion 34
Since one of the connecting edges 34A between the main roller 20 and the recess 35 is located between the center of the main roller 20 and the roller gap 23, the protrusion 34 can be easily deformed without any problem.

Further, even if the convex portion 34 is deformed, the concave portion 35 is substantially trapezoidal like the convex portion 34, so the concave portion 35
5 tearing can be suppressed.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The present invention is not only equipped with the onion harvester shown in FIG. 3, but also with an onion harvester not shown.

In FIGS. 1 and 2, a main roller 20 having a smooth surface and a feed roller 21 having a helical protrusion 22 on its surface are arranged with a distance 23 between the rollers to form a conveyance member 24. A plurality of sets of conveying members 24 are arranged in rows in the horizontal direction on the harvester body.

In this case, the conveyance member 24 is configured such that one end thereof, that is, the elevator 4 side shown in FIG. 3 is high and the other end, that is, the conveyance terminal side is low.

The main roller 20 and the feed roller 21 are numbered 25, 2.
Since the onions 27 on the conveying member 24 are rotatable inwardly relative to each other as shown by 6 and because one end of the conveying member 24 is high and the other end is low, the onions 27 on the conveying member 24 are
It is conveyed in the direction 9 shown in the figure, that is, one of the longitudinal directions of the roller shaft.

Note that in the embodiment shown in FIG.
A tapping roller 29 having a helical protrusion 28 on its surface is provided below so as to be rotatable in the direction of arrow 30, and when the protrusion 28 comes into contact with the outer surface of the main roller 20, the stems and leaves 31 can be cut. has been done.

Further, in the embodiment shown in FIG. 2, a cutting cutter may be provided separately, or the foliage 31 may be cut by the protrusion 22 of the feed roller 21. Therefore, if the feed roller 21 has a cutting function, There are cases where it is present and cases where it is not.

A conveyance control member 32 is provided above the conveyance member 24 across the conveyance direction 9, and this control member 32 may be provided one or more at intervals in the longitudinal direction of the roller axis. There is.

The conveyance control member 32 is a support rod (mounting member) not shown.
A flexible plate body 33 is attached to the plate body 33, and the plate body 33 has convex portions 34 and concave portions 35 alternately at intervals in a direction transverse to the conveyance direction 9. Each of the portions 35 and 34 has a substantially trapezoidal shape.

Further, the convex portion 34 is laterally shifted in phase from the roller spacing 23 as indicated by the symbol L, and the concave portion 35 substantially corresponds to the roller spacing 23,
Moreover, the connecting edge 34 between the concave portion 35 and the convex portion 34
One side of A is the center of the main roller 20 and the roller interval 2
It is located between 3 and 3.

Therefore, the onions 27 placed randomly on the conveying member 24 and being conveyed in the longitudinal direction of the roller axis are subjected to resistance by the convex portions 35, but at this time, since they are being subjected to conveying force, they are not rotated. This ensures that the rollers are introduced into the roller gap 23.

(Effect of the invention) According to the invention, the conveyance control member 32 provided across the conveyance direction 9 on the conveyance member 24 having the roller gap 23 has a convex portion 34 that extends along the roller gap 23.
Since the phases are further shifted, there is no risk of imparting excessive resistance to the onions 27 during conveyance, and as the onions 27 are less likely to stagnate, it is possible to suppress the occurrence of scratches.

Further, the onion 27 received by the convex portion 34 is
The recess 35 is rotated by the conveying force, and the recess 35 substantially corresponds to the roller interval 23, and the recess 35 and the projection 34
Since one of the connecting edges 34A is located between the center of the main roller 20 and the roller interval 23, the convex portion 34 is caused by the conveying force of the onion 27.
The onion 27 can be reliably introduced into the roller gap 23 because the onion 27 can be easily deformed, and even if the convex part 34 is easily deformed, the concave part 35 is almost trapezoidal like the convex part 34, so the convex part 35 can be easily deformed. There is no tearing due to deformation of the portion 34, and thus the durability of the conveyance control member 32 is improved, damage to the onions 27 is prevented, and cutting and conveyance can be ensured.
