[0005] The crushing teeth are in the shape of circular gears, sleeved on the main shaft, and arranged in a plurality at equal intervals. The crushing teeth mechanisms on the two main shafts are arranged in a staggered manner.
[0006] The spiral teeth are arranged in a spiral shape at the end of the main shaft, and the spiral directions of the spiral teeth at two ends of the same main shaft are opposite.

After the material reaches the middle position, it is crushed by the crushing teeth in the middle part of the two main shafts and squeezed to the discharge port, which can effectively prevent blockage, continuously push the material, and improve the continuity of material discharge, and has a significant effect on the feeding of raw materials such as high-moisture content loess and red mud.

[0013] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.
[0014] like Figure 1 As shown, the technical solution proposed by the utility model is:
[0015] A double-axis spiral gear crushing feeding bin for preventing material blocking comprises a storage mechanism and a double-axis spiral gear crushing mechanism. The storage mechanism consists of a bin frame 2 and a bin 1 welded to the bin frame 2. The double-axis spiral gear crushing mechanism comprises parallel main shafts driven by a motor 3. The parallel main shafts pass through the lower end of the bin 1. Spiral gears 14 are arranged at the two ends of the two main shafts located in the bin 1, and crushing teeth 15 are arranged in the middle of the main shafts.
[0016] Among them, the silo 1 is set at a large inclination angle, and there is no dead corner for material jamming.
[0017] The parallel main shafts are respectively a first main shaft 12 and a second main shaft 13 , and the first main shaft 12 and the second main shaft 13 rotate in opposite directions.
[0018] The spiral teeth 14 are arranged in a spiral shape at the end of the main shaft, and the spiral directions of the spiral teeth 14 at both ends of the same main shaft are opposite. The material falls to the top of the main shaft under the action of gravity, and the spiral teeth 14 squeeze and push the material toward the middle.
[0019] The crushing teeth 15 are circular gear-shaped, sleeved on the main shaft, and arranged in equal intervals. The crushing teeth 15 on the two main shafts are staggered. After the material reaches the middle position, it is crushed and discharged through the crushing teeth 15 in the middle of the two main shafts, which can effectively prevent blockage.
[0020] Furthermore, the spiral shifting teeth 14 and the crushing teeth 15 are fixed on the two main shafts by, but not limited to, welding.
[0021] The motor 3 is fixed to the silo frame 2 by bolts, the reducer 7 is fixed to the silo frame 2 by bolts, the first pulley 4 is fixed to the output shaft of the motor 3 by a key, the first pulley 4 is connected to the second pulley 6 by a belt 5, the second pulley 6 is fixed to the input shaft of the reducer 7 by a key, the output shaft of the reducer 7 is inserted into the input end of the coupling 8 and fixed by a key; the bearing seats 11 are respectively connected to the two ends of the first main shaft 12 and the second main shaft 13, the bearing seats 11 are fixed on the silo frame 2, and the ends of the first main shaft 12 and the second main shaft 13 close to the motor 3 are respectively fixedly connected to the second gear 10 and the first gear 9 by keys, and the first gear 9 and the second gear 10 are meshed and connected; the end of the second main shaft 13 located outside the first gear 9 is inserted into the output end of the coupling 8.
[0022] When working, the motor 3 is powered on, the first pulley 4 drives the second pulley 6 to rotate through the belt 5, the second pulley 6 drives the reducer 7 to rotate, the reducer 7 drives the second main shaft 13 to rotate through the coupling 8, the first gear 9 drives the second gear 10 to rotate through the meshing connection, and the first main shaft 12 and the second main shaft 13 realize counter-rotation. The loader puts the material into the silo 1, and the material falls to the double-axis spiral tooth crushing mechanism by gravity. The spiral teeth 14 on both sides of the main shaft push the material to the middle position, and the crushing teeth 15 in the middle position crush the material and squeeze it to the discharge port 16.
[0023] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
