There is a gap between the horizontal baffle flange and the top of the vibrating chute plate, and there is a gap between the vertical baffle flange and the vibrating chute plate. The bottom of the vertical baffle flange is below the top of the vibrating chute plate, which can prevent coal from entering through the gap between the top baffle and the top of the vibrating chute plate and better prevent coal accumulation.

[0008] As a preference, a guiding support rod is fixed in the middle of the vibrating chute plate. The outer end of the guiding support rod passes through the chute of the dustpan and is fixed with a mounting plate. The vibrating motor is fixed on the mounting plate. A shock-absorbing rubber pad is sleeved on the guiding support rod outside the chute of the dustpan. A guiding sleeve is sleeved outside the shock-absorbing rubber pad, and the guiding sleeve is fixed on the chute of the dustpan. A limit nut is threadedly connected to the guiding support rod below the shock-absorbing rubber pad, which can better perform vibration buffering.

[0009] As a preference, guiding screw rods are fixed at both the upper and lower ends of the vibrating chute plate. The outer ends of the guiding screw rods pass through the chute of the dustpan and are fixed with adjusting nuts. A guiding sleeve is sleeved outside the guiding screw rods, and the guiding sleeve is fixed on the chute of the dustpan. A spring is sleeved on the guiding screw rods. One end of the spring contacts the adjusting nut, and the other end of the spring contacts the guiding sleeve, which can better perform vibration buffering and guiding at both ends of the vibrating chute plate.

[0010] As a preference, material guiding plates are arranged above both sides of the conveyor belt. Wear-resistant rubber plates are fixed at the bottoms of the material guiding plates, and the bottoms of the wear-resistant rubber plates contact the tops of the conveyor belt. The material guiding plates and the wear-resistant rubber plates can prevent coal from falling into areas outside the conveyor belt. A rubber buffer backing plate is arranged between the chute of the dustpan and the vibrating chute plate. The rubber buffer backing plate is fixed on the chute of the dustpan, and there is a gap between the rubber buffer backing plate and the vibrating chute plate, which can better perform buffering.

[0011] The utility model has the following beneficial effects:

[0012] By arranging a vibrating chute plate parallel to the chute of the dustpan above the chute of the dustpan, when pouring and conveying the coal flow, the vibrating chute plate can be driven to vibrate by the vibrating motor, which can better prevent coal accumulation on the chute of the dustpan and facilitate the conveying of the coal flow.
