[Industrial applications]

 The present invention relates to a conveyor belt for a crop harvester and a driving device using the conveyor belt. More specifically, the crop belt to be harvested is a rubber belt having a corrugated surface attached to the back of the belt. The present invention relates to a conveyor belt for a crop harvester, which is wound around a pulley in a state of being closely attached, and is moved between rubber bands by sandwiching a conveyor made of agricultural products such as carrots so as not to damage it, and a drive device using the conveyor belt.

[0002]

[Prior art]

 A conventional conveyor belt that moves by sandwiching leaves, stems, etc. of agricultural products has a structure in which a rubber band having a corrugated surface is attached to a belt body in which a core wire is embedded. This pair of belts is wound and arranged with the rubber bands facing each other, and is attached to the crop harvester. The leaves and stems of agricultural products such as carrots are sandwiched between opposing rubber bands, extracted from the soil, and then transported. Here, in order to avoid damage to the agricultural products being transported, the corners of the rubber band were rounded and used.

For example, the applicant first made round corners at both ends of the rubber band in the traveling direction, and gradually increased the distance between both ends of the closely adhered rubber bands toward the outside. As a result, we proposed a belt that can firmly pinch the carrier, and that the carrier is not rubbed by the corners and damaged or cut even if the carrier vibrates during movement.

[0004]

[Problems to be solved by the device]

 As described above, in the conventional belt, a rubber band having a corrugated surface with a smooth surface is used in the belt body. By engaging a pair of belts having this corrugated surface with each other, it was devised to increase the gripping force. However, for example, when ginseng was taken out of the soil, it could fall because of insufficient clamping force. In other words, when carrots were taken out, a stronger gripping force was required than when they were transported, but the average gripping force could only be exerted due to the smoothness of the surface. Is. In particular, when the carrier is wet, the gripping force is further reduced, and the carrier may drop during transportation.

The present invention solves such a problem, and provides a conveyor belt for a crop harvester and a drive device using the conveyor belt, which can accurately extract and convey the conveyor without dropping the conveyor. The purpose is to do.

In the figure, in a drive device 1 for a conveyor belt for a crop harvester, a pair of belts 2 and 2 having a rubber band 5 having a corrugated surface 9 on a belt main body 3 in which a core wire 4 is embedded, and a protrusion 10 thereof are provided. The drive pulley 6, the driven pulley 7, and the intermediate pulley 8 are wound around and disposed in close contact with each other. A carrier 11 made of agricultural products such as carrots has leaves 12 sandwiched between rubber bands 5, 5 each having a plurality of protrusions 10 formed on its corrugated surface 9 and extracted from the soil. To be done. In the present embodiment, the shape of the protrusion 10 peculiar to the present invention is such that a plurality of concave and convex groove-shaped protrusions are formed in the belt longitudinal direction, but the shape is not limited to the above, and the shape is not limited to the above. Alternatively, a plurality of protrusions such as hemispheres may be used.

The belt 2 has a belt body 3 in which a core wire 4 made of polyester fiber, polyamide fiber, aramid fiber, or glass fiber is embedded in rubber such as natural rubber, SBR, NBR, CR, EPDM, or the like. It has a structure in which a rubber band 5 having a smooth corrugated surface 9 composed of a curve or a higher-order polynomial curve is attached. The height difference of the smooth corrugated surface 9 of the rubber band 5 is preferably in the range of 20% to 250% of the thickness T 1 of the belt body 3. The belt main body 3 is composed of a drive unit connecting two V-belts, and the rubber band 5 is composed of vulcanized rubber such as natural rubber, SBR, NBR, CR, EPDM, etc., which are joined and integrated. The protrusion 10 can be made of the same material by integrally molding with the rubber band 5, but it can also be formed into an optimum uneven pattern by sticking a protrusion made of rubber, resin, or metal. . Further, the height and array pitch of the above-mentioned protrusions may be any that is suitable for the size of the target agricultural product, that is, an effective wedge effect can be exerted between the protrusions that are in close contact with each other and the carrier. The maximum thickness H 1 of the rubber band 5 is preferably 1% to 50%, that is, 100 to 2 equal parts. The rubber of the belt body 3 may contain short fibers such as nylon, polyester, aramid and cotton for the purpose of abrasion resistance.

Further, in the drive device 1 of the present invention, both end corners of the rubber band 5 in the traveling direction and each corner of the protrusion can be appropriately formed into a circular arc shape. The size of this arc is due to the edges of each corner of the carrier 11 such as carrots being pinched, causing damage to the carrier 11 such as carrots even when the carrier 11 is being pulled out or under vibration during transfer. Any curvature is acceptable, and the size is not particularly limited.
