[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Please see Figures 1-3The rapid feeding device for a rotary drum furnace includes a hopper 100. A servo motor 200 is mounted on the side of the hopper 100, and a spiral blade 300 is connected to the side of the servo motor 200. The top of the hopper 100 has a feed inlet 400, the bottom of the hopper 100 has a discharge outlet 500, and the sides of the hopper 100 have two discharge outlets 600. The two discharge outlets 600 are located on opposite sides of the hopper 100 and are oval-shaped holes, edged with flat iron after drilling. Raw materials are placed into the hopper 100 through the feed inlet 400. Starting the servo motor 200 drives the spiral blade 300, causing the raw materials to move and discharge through the bottom discharge outlet 500 and the two side discharge outlets 600, thus increasing the discharge speed of the device.

[0022] In use, the raw material is placed in the hopper 100 through the feed inlet 400. The servo motor 200 is started, which drives the spiral blade 300 connected to it to rotate, causing the raw material to move and discharge through the bottom discharge port 500 and the two side discharge ports 600.

[0023] Example 2

[0024] Please see Figures 1-3Based on Embodiment 1, an auxiliary component 700 is provided on the side of the hopper 100. The auxiliary component 700 includes a fixed rod 701, and a bevel gear 702 is driven to the side of the spiral blade 300. When the spiral blade 300 rotates, it drives the bevel gear 702, which is driven to rotate. A bevel gear 703 is rotatably connected to the bottom of the fixed rod 701. The bevel gear 703 is located on the side of the bevel gear 702 and is meshed with the bevel gear 702. When the bevel gear 702 rotates, it drives the meshing bevel gear 703 to rotate. A transmission rod 704 is fixedly connected to the bottom of the bevel gear 703. When the bevel gear 703 rotates, it drives the transmission rod 704, which is fixedly connected to it, to rotate. A fixed frame 705 is fixedly connected to the side of the hopper 100. A reciprocating screw 706 is fixedly connected to the bottom of the transmission rod 704. A sliding block 707 is mounted on the outer side of the reciprocating screw 706. The sliding block 707 passes through the fixed frame 705 and is slidably connected to the fixed frame 705. When the transmission rod 704 rotates, it drives the reciprocating screw 706 fixedly connected to it to rotate. The sliding block 707, mounted on the outer side of the reciprocating screw 706 and restricted by the fixed frame 705, causes the sliding block 707 to reciprocate vertically. A clearing rod 708 is fixedly connected to the side of the sliding block 707. When the sliding block 707 reciprocates vertically, it drives the clearing rod 708 fixedly connected to it to reciprocate within the discharge port 500 for clearing. A conveyor belt 709 is mounted on the outer side of the drive rod 704. A force-bearing rod 710 is rotatably connected to the bottom of the hopper 100. The end of the conveyor belt 709 away from the drive rod 704 is located on the outer side of the force-bearing rod 710. When the drive rod 704 rotates, it cooperates with the conveyor belt 709 mounted on its outer side, causing the force-bearing rod 710, which is driven by the conveyor belt 709 and the drive rod 704, to rotate. An elastic cam 711 is fixedly connected to the outer side of the force-bearing rod 710. When the force-bearing rod 710 rotates, it drives the elastic cam 711 fixedly connected to it to rotate, causing it to strike the discharge port 500 and generate a certain vibration. This prevents the discharge port 500 from becoming blocked and improves the efficiency of the device.

[0025] In use, based on Embodiment 1, when the spiral blade 300 rotates, it drives the bevel gear 702 connected to it to rotate, which in turn drives the bevel gear 703 meshing with it to rotate. The bevel gear 703 drives the transmission rod 704 fixedly connected to it to rotate, which in turn drives the reciprocating screw 706 fixedly connected to it to rotate. The sliding block 707 is mounted on the outside of the reciprocating screw 706 and is restricted by the fixing frame 705, so that the sliding block 707 moves back and forth in the vertical direction, which drives the unblocking rod 708 fixedly connected to it to move back and forth in the discharge port 500 to unblock the flow. The rotating transmission rod 704, in conjunction with the conveyor belt 709 mounted on its outside, causes the force rod 710, which is connected to the transmission rod 704 via the conveyor belt 709, to rotate. The force rod 710 drives the elastic cam 711 fixedly connected to it to rotate, causing it to strike the discharge port 500 and generate a certain vibration.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
