It is arranged in. In the present invention, the left and right idlers are changed to idler assemblies consisting of four idler pulleys, which are traversed orthogonally above the rubber belts, hold down the rubber belts, and turn the lifting belt conveyor obliquely upward. It is to let.

That is, the idler assembly includes two outer idler pulleys having a lower periphery in contact with both edges of the rubber belt, two central idler pulleys having a lower periphery in contact with the center of the rubber belt, and these outer idler pulleys. An idler shaft that communicates and fixes the center of the idler pulley at the center, a bearing plate that supports the idler shaft, a scraper that sandwiches the outer idler pulley and the center idler pulley, and whose tip approaches the idler shaft. And a U-shaped frame fixed to the inner surface.

The bearing plates are provided at the front ends of the left and right base belt conveyor machine frames, and support the idler shaft by crossing the rubber belt directly above the rubber belt. The U-shaped frame has both sides fixed to the left and right bearing plates, and is laterally installed obliquely upward in front of the outer idler pulley and the center idler pulley.

Further, in order to prevent the granular material from spilling and falling from both sides of the lifting belt conveyor, the belt receiving rollers are inclined inwardly toward each other before and after the inside of the intermediate portion of the lifting belt conveyor conveyor frame. It can be set up and down freely. The belt receiving roller is rotatably supported on the upper end of an arm attached to the left and right sides of the boss so as to be rotatable. A shaft is connected to the boss and fixed, and one end of the shaft is lifted by a lifting belt conveyor frame. To one side, and fix the lever to the protruding end.

When the lever is turned backward, the shaft turns and the arm stands up, and the belt receiving roller contacts the back surface of the rubber belt of the conveyor, so that both edges of the rubber belt can be lifted. The rubber belt whose both edges have been lifted has a vertical section that curves like a ship bottom. Therefore, the powders and granules are prevented from collecting at the center of the rubber belt and spilling from both edges of the rubber belt.

In order to stop the upright arm at that position, a belt receiving roller stopper that contacts the front end face of the arm from the front is provided inside the lifting belt conveyor machine frame. When the lever is pivoted forward to release the lifting of both edges of the rubber belt, the arm falls down and the belt receiving roller is separated from the back surface of the rubber belt.

Is provided with an outer idler pulley whose lower circumference touches both edges of the rubber belt, and two central idler pulleys whose lower circumference touches the center of the rubber belt, so that the rise of the center of the rubber belt is suppressed, It is possible to eliminate spills of powder and granules from both edges of the rubber belt at the diverted portion of the belt conveyor.

Further, since the scrapers are provided on both sides of the outer idler pulley and the center idler pulley, the powder attached to the side surfaces of the idler pulley can be scraped off, and the idler pulley can be rotated lightly.

Further, belt receiving rollers are provided on the front and rear inner sides of the belt conveyor machine frame, which are freely raised and lowered by levers, and are inclined inwardly with respect to each other. Can be curved to the bottom of the ship in a longitudinal section, so that the powder and granules conveyed diagonally upward by the lifting belt conveyor can be collected at the center of the rubber belt, and can be prevented from spilling from both sides of the rubber belt.
