[0005] A stone conveying mechanism includes a mounting frame, a conveyor belt connected to the mounting frame, a hopper, a scraper, and a pipe connected to the lower opening of the hopper.

[0006] The conveyor belt transports crushed stone to the bunker. When the conveyor belt passes through the scraper, friction occurs between the surface of the conveyor belt and the scraper, which scrapes off the stone powder on the surface of the conveyor belt and drops it into the hopper. The stone powder is then transported from the hopper to the processing equipment through the pipe, reducing material waste.

[0007] Preferably, the connecting mechanism includes two L-shaped connecting plates, which are hinged to the upper sides of the hopper. The horizontal plate of each connecting plate has a connecting piece hinged to the upper end of one side, and a vertical pressing piece hinged to the other end. A rotor is hinged to the connecting point of the pressing piece and the connecting piece on the same side of the connecting plate. A bolt is threaded through the connecting piece and connected to the rotor.

[0008] The technical scheme is adopted, when the hopper is installed at the bottom of the conveying belt mounting frame, the two connecting plates are respectively turned to two sides, the distance between the two connecting plates is increased, the pressing plates are hooked to the cross bars on two sides of the mounting frame, the hopper is hung on the mounting frame, then the bolts are screwed, the bolts move to the middle of the hopper, the moving bolts are turned under the action of the connecting plates, so that the bolts push the pressing plates to turn, the cross bars of the mounting frame are pressed tightly, the hopper is fixed with the mounting frame, and the hopper is taken off from the mounting frame, the bolts on two sides of the hopper are screwed, the pressing plates are reversely turned, the force between the pressing plates and the cross bars is reduced, the hopper is moved upward, the cross bars are separated from the pressing plates and the connecting plates, then the connecting plates are turned to two sides, and the hopper is taken off from the mounting frame.

[0009] Preferably, a torsion spring is connected between the connecting plate and the hopper.

[0010] The technical scheme is adopted, when the connecting plates are turned to two sides, the torsion spring generates a force on the connecting plates, the connecting plates are prevented from being too loose, and the fixing of the hopper is affected.

[0011] Preferably, a rubber pad is fixedly connected to the surface of the pressing plate.

[0012] The technical scheme is adopted, the force between the pressing plate and the cross bar of the mounting frame is increased, and the hopper is more stably fixed on the mounting frame. BRIEF DESCRIPTION OF DRAWINGS
