In this device 1, each corner portion 10 of the rubber band 5 is rounded, and the intervals at both ends of each rubber band 5 that are in close contact with each other gradually increase outward.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drive device for a conveyor belt used in a crop harvesting machine. Specifically, a crop belt to be harvested is pasted with a rubber band having a corrugated surface, and a pair of belts are closely attached to each other. The present invention relates to a drive device for a conveyor belt used for a crop harvester, which is arranged around a pulley in a state of being wound, and in which a conveyor made of agricultural products such as carrots is sandwiched and moved so as not to damage it.

[0002]

[Prior art]

 A conventional conveyor belt for sandwiching and moving leaves of agricultural products has a structure in which a cushion body having a corrugated surface is attached to a belt body in which a core wire is embedded. This pair of belts are wound around the cushions so that they are facing each other, and are attached to a harvesting machine or the like. The leaves of agricultural products such as carrots are sandwiched between the opposing cushions, extracted from the soil, and then transported. Here, a soft sponge elastic body was used to avoid damage to the agricultural products being transported.

For example, Japanese Patent Publication No. 59-21299 discloses that a sponge belt has a linear posture in order to prevent peeling at an adhesive joint even if it is repeatedly bent for a long time. There is disclosed a belt in which sponge belts are connected so that a compressive internal stress in the belt circumferential direction is applied near the outer peripheral surface of the connecting portion.

[0004]

[Problems to be solved by the device]

 However, since the conventional belt uses a sponge band, when the carrot leaves are sandwiched between the cushions that are facing each other and transported, the gripping force of the transported product is insufficient and the transported product falls. There was something to do. Further, when the conveyed product was wet, the gripping force was further reduced.

Further, as a major problem, there is a problem that a conveyed product vibrating during movement is rubbed by the corner portion of the sponge belt and damaged or cut. The present invention solves such a problem, and provides a drive device for a conveyor belt used in a crop harvester, which can reliably transport a conveyed product without damaging or cutting it. To aim.

[0006]

[Means for Solving the Problems]

 That is, a feature of the present invention is that a pair of belts having a structure in which a rubber band having a corrugated surface is attached to a belt main body in which a core wire is embedded is driven by a drive unit and a driven unit in a state in which each rubber band is in close contact. It is a drive device for a conveyor belt used in an agricultural crop harvester that is placed around a rubber band and moved with the carrier sandwiched between the rubber bands. This is a drive device for a conveyor belt used in a crop harvester, in which the distance between the ends of the rubber band gradually increases outward.

[0007]

[Action]

 In the drive device for the conveyor belt used in the agricultural crop harvester of the present invention, each corner portion of the rubber band is rounded, and the intervals at both ends of the closely attached rubber bands are gradually expanded outward. As a result, it is possible to firmly and securely hold the conveyed product, and even if the conveyed product vibrates during movement, it is less likely to be rubbed at the corner and damaged or cut.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a drive device for a conveyor belt used in a crop harvesting machine according to the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a sectional view showing a state where a conveyed product is clamped. . In the figure, in a conveyor belt driving device 1 used in a crop harvester, a pair of belts 2 and 2 having a structure in which a rubber band 5 having a corrugated surface is attached to a belt body 3 in which a core wire 4 is embedded, The rubber belts 5 and 5 are closely attached to each other and wound around the drive pulley 6, the driven pulley 7, and the intermediate pulley 8. When the leaves 12 of the carrier 11 made of agricultural products such as carrots are sandwiched between the rubber bands 5 and 5, they are extracted from the soil and transported.

The belt 2 has a sinus or cos-shaped curve in a belt body 3 in which a core wire 4 made of polyester fiber or polyamide fiber is embedded in rubber such as natural rubber, SBR, NBR, or CR. It has a structure in which a rubber band 5 having a corrugated surface is attached. 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, and CR, which are joined and integrated. The rubber of the belt body 3 may contain short fibers such as nylon, polyester, aramid, and cotton.

Therefore, in the drive device 1 of the present invention, each corner portion 10 of the rubber band 5 is rounded like an arc, and the distance between the ends of the closely attached rubber bands 5, 5 is outward. It is gradually expanding. The size of this arc is usually an arc of 5 to 50 mm, and the size of the arc is not particularly limited. As a result, the carrier 11 such as a carrot having the leaves 12 sandwiched between the rubber bands 5 and 5 is not damaged at the corner portion 10 even if it is subjected to vibration during transportation.

[0011]

[Effect of device]

 As described above, in the drive device for the conveyor belt used in the crop harvesting device of the present invention, the corners of the rubber band are rounded, and the intervals at both ends of the closely attached rubber bands gradually increase toward the outside. By doing so, it is possible to firmly and reliably hold the conveyed product, and even if the conveyed product vibrates during movement, it is less likely to be rubbed at the corners and damaged or cut.
