[0028] Example 1

[0029] A powder storage device, such as Figures 1 to 4As shown, it includes a storage barrel 1 supported on the bottom surface by a support frame 2, the bottom end of the storage barrel 1 is conical, the top of the storage barrel 1 is connected to a discharge box 3, the bottom of the discharge box 3 is connected to a temporary storage box 4, the storage barrel 1 is connected to a stirring shaft 7 by rotation, a stirring motor 5 is fixed to the outer wall of the top of the storage barrel 1, the output shaft of the stirring motor 5 is connected to the stirring shaft 7, the outer wall of the stirring shaft 7 is connected to a stirring frame 8, and a feed port 6 is arranged on one side of the outer wall of the top of the storage barrel 1, and the top of the feed port 6 It is closed by a sealing cover, the inner wall of the discharge box 3 is rotatably connected to a rotating block 14, and the side wall of the rotating block 14 is provided with a plurality of material receiving cavities 15 arranged in a circular array, and both sides of the outer wall of the bottom end of the temporary storage box 4 are rotatably connected to box doors 17 through torsion springs 18, and the two box doors 17 are arranged opposite to each other, and the side wall of the temporary storage box 4 is provided with an electric telescopic plate 19, and the gap between the electric telescopic plate 19 and the two box doors 17 is located in the same straight line, and the electric telescopic plate 19 is limited by the two box doors 17.

[0030] When in use, fill the material into the storage barrel 1 through the feed port 6. During the storage process, the stirring motor 5 drives the stirring shaft 7 to rotate, so that the stirring frame 8 stirs the material inside the storage barrel 1 to prevent the internal material from being partially damp and causing large-scale damage to the material. When discharging, the rotating motor 16 drives the rotating block 14 to rotate. When the receiving cavity 15 on the rotating block 14 moves to the bottom of the storage barrel 1, the material falls into the receiving cavity 15. When the receiving cavity 15 filled with the material rotates 180 degrees, the material falls into the temporary storage box 4 due to gravity, so that the material is discharged. The continuous but intermittent discharge flow reduces the accumulation of materials at the same position and avoids discharge blockage. At the same time, the stirring motor 5 drives the stirring shaft 7 to stir. Since the volume of the receiving chamber 15 is fixed, the quantitative discharge of the material can be achieved by controlling the number of times the receiving chamber 15 receives and discharges the material. When the material in the temporary storage box 4 reaches the take-out amount, the electric telescopic plate 19 contracts to release the limit on the box door 17. The weight of the material in the temporary storage box 4 overcomes the force of the torsion spring 18 to drive the box door 17 to close, so that the box door 17 opens, and the material temporarily stored in the temporary storage box 4 flows out.

[0031] By providing the discharge box 3, the rotating block 14, the material receiving chamber 15 and the rotating motor 16, the material can be discharged in a continuous but discontinuous manner, thereby reducing the accumulation of materials at the same position and avoiding discharge blockage.

[0032] By providing the temporary storage box 4, the box door 17, the torsion spring 18 and the electric telescopic plate 19, when the material in the temporary storage box 4 reaches the take-out amount, the electric telescopic plate 19 contracts to release the limit on the box door 17, and the weight of the material in the temporary storage box 4 overcomes the force of the torsion spring 18 driving the box door 17 to close, so that the box door 17 opens, and the material temporarily stored in the temporary storage box 4 flows out, so that a large amount can be taken out at one time, and quantitative removal of materials can be achieved without stopping the rotation of the rotating block 14, thereby improving the operating efficiency.

[0033] Example 2

[0034] A powder storage device, based on the embodiment 1, this embodiment makes the following improvements, such as Figure 2 , Figure 5 As shown, the stirring shaft 7 is connected to the output shaft of the stirring motor 5 through a hollow shaft 11, a cavity 9 is opened inside the stirring shaft 7, the inner wall of the cavity 9 is rotatably connected with a rotating shaft 10, the other end of the rotating shaft 10 passes through the stirring shaft 7 and is fixedly connected to the inner wall of the storage barrel 1, a plurality of active bevel gears 12 are fixed to the outer wall of the rotating shaft 10, the inner wall of the stirring shaft 7 is rotatably connected with a driven bevel gear 13, the driven bevel gear 13 is in transmission meshing with the active bevel gear 12, and the stirring frame 8 is connected to the rotating shaft of the driven bevel gear 13.

[0035] When the stirring shaft 7 rotates, since the rotating shaft 10 is fixed, the active bevel gear 12 drives the driven bevel gear 13 to rotate, so that the stirring frame 8 rotates while revolving with the stirring shaft 7, and the stirring effect is better. At the same time, due to the rotation of the stirring shaft 7, the active bevel gear 12 and the driven bevel gear 13 rotate relative to each other, without the need for an additional power source, and the structure is more compact.

[0036] By arranging the hollow shaft 11, the rotating shaft 10, the driving bevel gear 12 and the driven bevel gear 13, when the stirring shaft 7 rotates, since the rotating shaft 10 is fixed, the driving bevel gear 12 drives the driven bevel gear 13 to rotate, so that the stirring frame 8 can rotate while revolving with the stirring shaft 7, so as to achieve a better stirring effect. At the same time, since the rotation of the stirring shaft 7 is utilized, the driving bevel gear 12 and the driven bevel gear 13 can rotate relative to each other, and there is no need to set up an additional power source, so the structure is more compact.

[0037] Working principle: When in use, fill the material into the storage barrel 1 through the feed port 6. During the storage process, the stirring motor 5 drives the stirring shaft 7 to rotate, causing the stirring frame 8 to revolve. At the same time, since the rotating shaft 10 is fixed, the active bevel gear 12 drives the driven bevel gear 13 to rotate, causing the stirring frame 8 to rotate while revolving with the stirring shaft 7, so as to stir the material inside the storage barrel 1 to prevent the internal material from being partially damp and causing large-scale damage to the material. When discharging, the rotating motor 16 drives the rotating block 14 to rotate. When the receiving cavity 15 on the rotating block 14 moves to the bottom of the storage barrel 1, the material falls into the receiving cavity 15. When the receiving cavity filled with material After the cavity 15 rotates 180 degrees, the material falls into the temporary storage box 4 due to gravity, so that the material can be discharged continuously but intermittently during discharge, reducing the accumulation of materials at the same position and avoiding discharge blockage. At the same time, the stirring motor 5 drives the stirring shaft 7 to stir. Since the volume of the receiving cavity 15 is fixed, the quantitative discharge of the material can be achieved by controlling the number of times the receiving cavity 15 receives and discharges the material. When the material in the temporary storage box 4 reaches the removal amount, the electric telescopic plate 19 contracts to release the limit on the box door 17. The weight of the material in the temporary storage box 4 overcomes the force of the torsion spring 18 to drive the box door 17 to close, so that the box door 17 opens, and the material temporarily stored in the temporary storage box 4 flows out.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
