になる。According to the present invention, one jet nozzle is installed in the lower part of the center of the return belt in the width direction, and water is jetted to 1/3 of the central portion of the conveyor belt immediately before the feed roller entrance side. This jet water spreads over the entire width of the conveyor belt surface on the contact surface between the conveyor belt and the draining roller (feed roller).
Form a water film. This water film is blocked at the contact surface between the belt and the roll, and then swirled and corrugated by the force of the movement of the belt and the rotation of the roll, thereby producing a cleaning effect. Therefore, the cleaning water does not need to be sprayed over the entire width of the belt, and therefore the adhered substances on the belt surface can be efficiently removed by using a small amount of low pressure water.

If it is less than or equal to / 3, the cleaning water does not spread over the entire width of the belt, and the effect of removing deposits is reduced.

洗浄水をスプレーする。FIG. 1 is an explanatory side view showing an example of a conveyor belt rinsing device of the present invention, FIG. 2 is an enlarged view of the rinsing portion of FIG. 1, and FIG. It is explanatory drawing of the front which shows a condition. As shown in FIG. 1, the return belt 1 passing through the head snubb pulley 7 has its trough property (transverse cross-sectional shape) corrected by the pressing roller 3a. After that, the draining roller (feeding roller) 2a is arranged at the subsequent stage of the pressing roller 3a. Immediately before the water draining roller 2a, one sprinkling nozzle 4a sprays cleaning water onto one return belt in a range of about one third of the central portion of the return belt 1.

可能になった。In this way, the cleaning water sprayed onto the approximately one-third portion of the surface of the belt 1 in the width direction is washed with water by the drain roller 2.
A water film is formed on the entire surface of the roller while being stretched over the entire width of the belt at the moment of being pressed to a. At the same time, the formed water film rotates together with the roller to clean the return belt 1 so as to knead dust adhering to the surface thereof. The drain roller 2a also functions as a feed roller by adjusting the pressing of the pressing roller 3b against the belt. At this time, the cleaning water spraying pressure of the cleaning nozzle is only the minimum required pressure for spraying in a fan shape, and in the embodiment, it is 0.5 kg / cm 2 or less. The amount of water used was a small amount of 5 to 10 liters / min. As a result of carrying out the ore and coal transportation under the above conditions,
The deposits on the belt surface could be removed well. In addition, the belt surface after washing was well drained, which enabled stable operation.
