[0009] Preferably, the stress-bearing rod passes through the protective cover, the stress-bearing rod is in contact with the outer spiral blade, and the stress-bearing rod is in the shape of a triangular prism.
[0010] Preferably, there are several outer spiral leaves and inner spiral leaves respectively. If the outer spiral leaves and inner spiral leaves are distributed in a ring shape on the fixed disk, the inner spiral leaves are located on the inner side of the outer spiral leaves, one end of the fixing rod is fixedly connected to the connecting rod, and the other end of the fixing rod passes through the inner spiral leaves and is fixedly connected to the outer spiral leaves.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0013] 1. By setting the spiral directions of the outer spiral blade and the inner spiral blade in opposite directions, when the fixed disk drives the outer spiral blade and the inner spiral blade to rotate, the outer spiral blade can transport the powder upward, while the inner spiral blade can transport the powder downward. The rotation of the outer spiral blade and the inner spiral blade causes the powder to be circulated and transported, thereby achieving a stirring effect on the powder and preventing the powder from being blocked inside the silo. At the same time, the bracket is fixed on the fixed frame. When the powder in the powder bag is poured into the silo, the bracket can support the powder bag to facilitate unloading and prevent the powder bag from acting on the fixed disk and affecting the rotation between the fixed disk and the fixed frame.
[0014] 2. By setting the frame on the inclined surface of the silo, the force-bearing rod is in contact with the outer spiral leaf. When the outer spiral leaf rotates, the outer spiral leaf will rise against the force-bearing rod. Since the force-bearing rod is set on the inclined surface of the silo, the contact area of the force-bearing rod with the outer spiral leaf will become smaller and smaller as it rises until there is no contact at all. When the force-bearing rod rises, the impact block moves with it and squeezes the shrapnel. When the force-bearing rod is no longer in contact with the outer spiral leaf, the shrapnel moves against the impact block, causing the impact block to hit the frame. Since the frame is fixed on the silo, the impact of the impact block will cause the silo to vibrate, shake off the powder, and further prevent the powder from accumulating and clogging.

The powder at the bottom will be completely discharged to form a cavity, and the powder at the top will be blocked and unable to fall. The anti-blocking component can stir the powder and effectively prevent the powder from being blocked. The transmission device 6 is connected to the conveying component, and the conveying component includes a rotating rod 5 and a conveying spiral blade 51. The rotating rod 5 is connected to the transmission device 6, and the conveying spiral blade 51 is fixed on the rotating rod 5. One end of the rotating rod 5 is connected to the reduction motor 13, and the other end of the rotating rod 5 is rotatably connected to the discharge port of the silo 1. The conveying component conveys the powder out of the silo 1 at a uniform speed, which is convenient for quantitative discharge of the powder. The inner wall of the silo 1 is fixed with a vibration component, which impacts and vibrates the silo 1 to shake the material off, further preventing the powder from being blocked.
[0023] See also Figure 1 、 Figure 2 and Figure 3The anti-blocking assembly comprises two fixed discs 4 arranged symmetrically up and down, the upper fixed disc 4 is rotationally connected with the fixed frame 3, outer spiral blades 41, inner spiral blades 42 and connecting rods 43 are fixed between the two fixed discs 4, a plurality of fixed rods 44 are fixed on the connecting rods 43, the fixed rods 44 are used for fixedly connecting the outer spiral blades 41 and the inner spiral blades 42, the spiral directions of the outer spiral blades 41 and the inner spiral blades 42 are opposite, the spiral directions of the outer spiral blades 41 and the inner spiral blades 42 are arranged oppositely, when the fixed disc 4 drives the outer spiral blades 41 and the inner spiral blades 42 to rotate, the outer spiral blades 41 can deliver the powder upwards, and the inner spiral blades 42 can deliver the powder downwards, the rotation of the outer spiral blades 41 and the inner spiral blades 42 enables the powder to be delivered in a circulating manner, the powder is stirred, the powder is prevented from being blocked in the silo 1, the outer spiral blades 41 and the inner spiral blades 42 are arranged in a plurality of sets, the outer spiral blades 41 and the inner spiral blades 42 are arranged in a ring shape on the fixed disc 4, the inner spiral blades 42 are located on the inner side of the outer spiral blades 41, one end of the fixed rod 44 is fixedly connected with the connecting rod 43, the other end of the fixed rod 44 penetrates through the inner spiral blade 42 and is fixedly connected with the outer spiral blade 41, the fixed rod 44 connects the outer spiral blade 41, the inner spiral blade 42 and the connecting rod 43, when the fixed disc 4 drives the outer spiral blades 41 and the inner spiral blades 42 to rotate and deliver the powder, the rigidity of the outer spiral blades 41 and the inner spiral blades 42 is increased, and the outer spiral blades 41 and the inner spiral blades 42 are prevented from being deformed greatly.
[0024] Please refer to Figure 3 , Figure 4 and Figure 5, the silo 1 is an isosceles trapezoid, the vibration assembly is fixed on the inclined surface of the silo 1, the vibration assembly includes a frame 7, an impact block 73 is slidably connected to the frame 7, a force rod 72 is fixed on the impact block 73, a spring piece 74 is provided in the frame 7, and a protective cover 71 is provided on the frame 7. The protective cover 71 moves along with the force rod 72 while it moves, covering the frame 7 to prevent powder from entering the interior of the frame 7, causing the spring piece 74 to be unable to deform normally, the force rod 72 passes through the protective cover 71, and the force rod 72 can contact the outer spiral leaf 41. By setting the frame 7 on the inclined surface of the silo 1, the force rod 72 contacts the outer spiral leaf 41. When the outer spiral leaf 41 rotates, the outer spiral leaf 41 will rise against the force rod 72. The force rod 72 is set on the inclined surface of the silo 1. As the force rod 72 rises, the area of contact with the outer spiral leaf 41 will become smaller and smaller until there is no contact at all. When the force rod 72 rises, the impact block 73 moves accordingly and squeezes the spring piece 74. When the force rod 72 is no longer in contact with the outer spiral leaf 41, the spring piece 74 moves against the impact block 73, causing the impact block 73 to hit the frame 7. Since the frame 7 is fixed on the silo 1, the impact of the impact block 73 will cause the silo 1 to vibrate, shake off the powder, and further prevent the powder from accumulating and clogging. The force rod 72 is a triangular prism. The force rod 72 is set to a triangular prism. When the force rod 72 moves downward, the force rod 72 can use its edges to quickly break the powder, causing the impact block 73 to hit the frame 7, thereby causing the silo 1 to vibrate.
[0025] See also Figure 1 、 Figure 2 and Figure 3 The lower end of the bracket 2 is fixed with multiple legs 21 along its circumference, and the legs 21 are fixed on the fixing frame 3. The reinforcing rod 31 at the lower end of the fixing frame 3 is fixedly connected to the silo 1, and a triangle is formed between the fixing frame 3, the reinforcing rod 31 and the silo 1. The bracket 2 is fixed on the fixing frame 3. When the powder in the powder bag is poured into the silo 1, the bracket 2 can support the powder bag to facilitate unloading, and at the same time prevent the powder bag from acting on the fixed plate 4 and affecting the rotation between the fixed plate 4 and the fixing frame 3. The reinforcing rod 31 is fixed at the lower end of the fixing frame 3 to form a triangle between the reinforcing rod 31, the fixing frame 3 and the silo 1. The reinforcing rod 31 further supports the fixing frame 3 to prevent the fixing frame 3 from deformation and increase the rigidity and load-bearing capacity of the fixing frame 3.
[0026] When using this utility model:
[0027] First, place the powder bag on the bracket 2 and pour the powder into the hopper 1. After completion, start the reduction motor 13 to work, and the reduction motor 13 drives the rotating rod 5 and the fixed plate 4 to rotate;
[0028] Then, the fixed disk 4 rotates to drive the outer spiral blade 41 and the inner spiral blade 42 to rotate. Since the spiral directions of the outer spiral blade 41 and the inner spiral blade 42 are set in opposite directions, when the fixed disk 4 drives the outer spiral blade 41 and the inner spiral blade 42 to rotate, the outer spiral blade 41 can transport the powder upward, while the inner spiral blade 42 can transport the powder downward. The rotation of the outer spiral blade 41 and the inner spiral blade 42 enables the powder to be circulated and transported, achieving a stirring effect on the powder, and preventing the powder from being blocked inside the silo 1;
[0029] Then, when the outer spiral leaf 41 rotates, the outer spiral leaf 41 will rise against the force-bearing rod 72. Since the force-bearing rod 72 is arranged on the inclined surface of the silo 1, the contact area of the force-bearing rod 72 with the outer spiral leaf 41 will become smaller and smaller as it rises until there is no contact at all. When the force-bearing rod 72 rises, the impact block 73 moves along with it and squeezes the spring piece 74. After the force-bearing rod 72 is no longer in contact with the outer spiral leaf 41, the spring piece 74 moves against the impact block 73, causing the impact block 73 to hit the frame 7. Since the frame 7 is fixed to the silo 1, the impact of the impact block 73 will cause the silo 1 to vibrate, causing the powder to fall.
[0030] Finally, after the powder reaches the conveying spiral blade 51, the rotating rod 5 drives the conveying spiral blade 51 to rotate and discharge the powder. At the same time, due to the real-time weighing of the heavy sensor 11, quantitative discharge of the powder can be achieved.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
