[0002] Before the crushed stone is mixed with asphalt, it is necessary to use a lifting mechanism to lift the crushed stone into the mixing device for mixing with the molten asphalt. At present, the lifting bucket of the chain elevator is often used to lift the crushed stone. The clay on the stone will cause part of the crushed stone to stick in the lifting bucket, making it impossible to completely unload; and when the crushed stone is mixed with asphalt, due to the high viscosity of the asphalt, the raw materials between the mixing plates are prone to accumulation during the mixing process phenomenon, resulting in poor mixing of gravel and asphalt
