要望される処であった。Prior art and its problems In general, the joints of annular belts used in belt conveyors, packet elevators, etc., use alligator joints or belts that connect metal fittings made of a large number of claw-shaped iron pieces that are driven into the belt and interlocked with each other. Belt connection fittings such as flexico fittings, which are fixed and connected with bold bolts, are commonly used, but although these fittings have excellent joint strength, they create many cuts or holes in the belt, making it difficult to connect the belt. The screw-type tensioning device that adjusts the tension of the annular belt has the disadvantage of reducing the strength (see Figures 3 and 4). It is necessary to adjust the horizontal angle of the car, so if there are no obstacles in the surrounding area, there is no problem with the adjustment work, but if the tensioning device is installed in a narrow bit like a packet elevator installed in a rice milling plant, etc. In such a case, it would be extremely difficult to adjust the horizontal angle of the belt pulley, and there was a strong demand for improvements to the device.

Reference numeral 1 designates a rotating roller body having an uneven surface 2 on its circumferential surface that is fixed by contact friction of the belt surface. A belt clamping plate 5 is fixed on the surface of the case 1 with an appropriate belt insertion gap 4 therebetween, and a rotating handle 8 equipped with a ratchet mechanism 7 is pivotally attached to the rotating shaft 6 of the roller body 1. The belt mount 9 provided on the i-stake belt 10 is fixed integrally with the belt end 11 on one side of the i-stake belt 10 by tightening the bolt 12, and 13 is a fixing protrusion protruding from the one side of the case 1. The rod 14 is a fixing metal fitting for fixing the fixing rod 13 to the belt surface, 15 is a fitting hole for the rod provided in the fixing metal fitting 14, and 16 is the other belt end of the annular belt 10. In addition, the ratchet mechanism 7 has a ratchet gear 18 rotatably attached to the inside of the machine frame 17 (see FIG. 1), and a pair of locking pawls 19A and 19B are provided on both sides of the upper part of the gear 18, and a pressing spring is provided. 2
0.20 respectively, and the locking lever 21 is rotated to lock or release the locking pawl 19A or 19B on the gear 18 as appropriate.

のに限定されないことはもちろんである。When adjusting the belt tension by connecting the annular belt 10, (see Figures 1 and 2), rotate the operating rod 2 of the ratchet mechanism 7 to the right in the figure, and rotate it against the gear 18. At the same time as the locking claw 19A is removed, the locking claw 19B is stopped in a locked state, and then the other belt end 16 of the annular belt 10 is inserted into the belt insertion interval 4 in the case 3. When the rotation handle 8 is reciprocated from side to side in the drawing while being fitted, the roller body 1 is rotated clockwise in the drawing together with the gear 18 by the locking pawl 19B. At this time, the uneven surface 2 provided on the circumferential surface of the roller body 1 presses the belt 10 surface and feeds it in the direction of the arrow in the figure, and the tension of the belt increases and is adjusted according to the amount of belt feed. Therefore, when a predetermined tension is reached, the operating rod 21 is set upright in the drawing, the locking pawl 19A is locked to lock the rotation of the gear 18, and the handle 8 is pivoted. The adjustment of the tension degree is completed when the tension is removed from the rotation shaft 6. The rotating handle 8 may be attached to the rotating shaft 6 and fixed onto the belt surface via a loose fitting part (not shown), or the structure of the rotating roller body 1 may be Of course, the rotating device is not limited to what is shown in the drawings.
