[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 In the utility model, a large-volume conical double-screw mixer includes a conical barrel 1. A motor 2 is installed on the upper surface of the conical barrel 1. The output end of the motor 2 passes through the conical barrel 1 and is transmission-connected to two screw rods 11. The motor 2 can drive the screw rods 11 to rotate inside the conical barrel 1, thereby completing the stirring of the material inside the conical barrel 1.

[0021] The output end of the motor 2 is fixedly connected to the hanging plate 6, and the inner top wall of the conical barrel 1 is provided with an annular groove 8. The inner wall of the annular groove 8 is rotatably connected with a ring-arranged stabilizing rod 9. The bottom end of each stabilizing rod 9 is connected to the upper surface of the hanging plate 6. The cooperation between the set annular groove 8 and the stabilizing rod 9 can further reinforce and stabilize the hanging plate 6, thereby ensuring the stability of the hanging plate 6 during rotation.

[0022] The outer surface of the hanging plate 6 is fixedly connected to two fixed cylinders 16, and the inner wall of each fixed cylinder 16 is fixedly connected to a spring 17. The end of each spring 17 close to the cone barrel 1 is fixedly connected to a sliding column 13, and the end of each sliding column 13 close to the cone barrel 1 is fixedly connected to a scraper 12. When the spring 17 extends, it will push the sliding column 13, and the sliding column 13 will push the scraper 12 to contact the cone barrel 1, so that the residue on the inner wall of the cone barrel 1 can be scraped off.

[0023] The two pull plates 14 are fixedly connected to a side surface away from each other with an anti-collision pad 19 . The anti-collision pad 19 can protect the pull plates 14 to prevent collision damage between the pull plates 14 and the fixed tube 16 .

[0024] A through groove 18 is provided on the outer surface of each fixed cylinder 16, and a pull plate 14 is fixedly connected to the outer surface of each sliding column 13. A frame 15 is sleeved on the outside of each pull plate 14, and two electric push rods 7 are installed on the upper surface of the hanging plate 6. The ends of the two electric push rods 7 that are away from each other are respectively connected to the side surfaces of the two frames 15 that are close to each other. When the electric push rods 7 retract, the frame 15 will pull the pull plate 14, and the pull plate 14 will drive the sliding column 13, and the scraper 12 will move away from the cone barrel 1, thereby preventing the scraper 12 from being in contact with the cone barrel 1 all the time and causing damage to the scraper 12 or the cone barrel 1.

[0025] The outer surface of the cone barrel 1 is fixedly connected to a feed pipe 3, and the bottom surface of the cone barrel 1 is fixedly connected to a discharge pipe 4. The staff can add materials into the cone barrel 1 from the feed pipe 3 and discharge materials outward from the discharge pipe 4.

[0026] The outer surface of the cone barrel 1 is fixedly connected with a ring-shaped supporting leg 5, which can stably support the cone barrel 1 and keep the cone barrel 1 in a stable state.

[0027] The working principle of the present utility model is: when the inner wall of the cone barrel 1 needs to be cleaned, the electric push rod 7 is started to extend, and the electric push rod 7 will drive the frame 15 to move. As the frame 15 moves, the spring 17 will extend the push slide 13, and the slide 13 will push the scraper 12 to contact the inner wall of the cone barrel 1. Then, the motor 2 is started to work, and the motor 2 will drive the hanging plate 6 to rotate. The hanging plate 6 will drive the scraper 12 to rotate around the cone barrel 1. When the scraper 12 rotates, it will scrape off the material remaining on the inner wall of the cone barrel 1, which is beneficial for subsequent use.
