At the same time, according to the characteristics of the material, the blades of the screw shaft are selected to rotate in the same direction, so that the material is pushed to the discharge port by the rotation direction of the blades of the screw shaft.
[0016] Furthermore, the rotating shaft is a blade screw shaft, the blades of the screw shaft rotate in both directions, the discharge port is located in the middle of the bottom of the bin, and the center of the blades of the screw shaft has a discharge port. The blades of the screw shaft located on one side of the discharge port have opposite rotation directions to the blades of the screw shaft located on the other side of the discharge port, and the rotation direction of the blades of the screw shaft are both in the direction of the discharge port.
[0017] The beneficial effect of adopting the above further scheme is that the spiral shaft with blades can break up the material through the blades of the spiral shaft, which can reduce the effects of large-volume storage bins on the material at the bottom, such as sedimentation, compaction, and arching, so that the material can be discharged smoothly.

[0018] Furthermore, there are a plurality of rotating shafts, and the plurality of rotating shafts are arranged side by side in sequence in the frame.
[0019] The beneficial effect of adopting the above further solution is that a plurality of rotating shafts are arranged side by side in the frame, so that more materials can be crushed and scattered and pushed to the discharge port.
[0020] Furthermore, the discharge port is square in shape.
[0021] The beneficial effect of adopting the above further solution is that the discharge port is square and rectangular, firstly to adapt to the feed port of the double spiral transfer device below it, and secondly to facilitate the push feeding of the spiral row, so that the discharge volume can be maximized.

[0100] like Figure 5 As shown, there are a plurality of rotating shafts 210 , and the plurality of rotating shafts 210 are sequentially arranged side by side in the frame 220 .
[0101] Specifically, a plurality of rotating shafts 210 are arranged side by side in the frame 220 , so that more materials can be crushed and dispersed and pushed toward the discharge port 231 .
[0102] like Figure 5 As shown, the discharge port 231 is square in shape.
[0103] Specifically, the material discharging port 231 is in a square shape and is rectangular, firstly to accommodate the material feeding port of the double spiral transfer device below it, and secondly to facilitate the pushing and feeding of the spiral row, so that the material discharging amount can be maximized.
[0104] like Figure 5 As shown, the storage bin body 100 is in a square or round shape, and the bottom of the storage bin body 100 is transitionally connected to the frame body 220 .
[0105] Specifically, when the amount of stored materials is large, a circular storage bin body 100 may be used. Since the lateral pressure of the circular bin body is balanced, the bin body panel will not be bent or deformed.
[0106] like Figure 5 As shown, the driving mechanism 300 includes a coupling 310, a gearbox 320 and a driving device 330. The output end of the driving device 330 is connected to the input end of the gearbox 320 through the coupling 310. The gearbox 320 is fixedly arranged on one side of the frame 220, and the output end of the gearbox 320 is connected to one end of the rotating shaft 210.
[0107] Specifically, the driving mechanism 300 includes a gearbox 320, so that the driving device 330 has the function of adjusting the speed, and the speed of the driving device 330 can be adjusted as needed, so that the discharge amount can be adjusted by adjusting the rotation speed of the screw shaft 211. In this embodiment, the driving device 330 is configured as a speed-adjustable motor reducer combination, and alternatively, the driving device 330 can also be a hydraulic motor, or other alternative rotary driving mechanism 300.
[0108] The beneficial effects of this embodiment are: the device has a simple structural design, and the connections between the structures are compact and stable. The device can not only break up the compacted materials at the bottom of the silo 230 through the multiple blade screw shafts 211, but also adjust the discharge amount by adjusting the rotation speed of the screw shafts 211. It can be applied to the storage and adjustable discharge of solid and semi-solid materials such as sandstone, powder, fine particles, and viscous pastes.
[0109] The working process of this embodiment is as follows: the material in the square storage bin body 100 enters the discharge device 200 , the material is broken up by the rotating shaft 210 , and is pushed to the bin bottom 230 by the rotating shaft 210 , and discharged from the discharge port 231 .
