In the chemical industry, silicon powder can be used to prepare silicone oil, silicone rubber, silicone resin and other organic silicon compounds, which are widely used in rubber, plastics, coatings, adhesives and other fields. In addition, silicon powder also has certain applications in building materials, refractory materials, ceramics, metallurgy and other fields.

[0003] When producing sodium silicate, there is a step of sprinkling silicon powder, which is basically completed by manpower. The operator uses a shovel to scatter the silicon powder.

The mechanical equipment has a simple structure and can only complete simple powder spreading operations. When the silicon powder is piled up in the mechanical equipment holding device, it is easy to pile up. After piling up, it cannot fall smoothly to complete the powder spreading operation. Manual intervention is required for stirring. The intervention of manpower will still make the powder spreading steps cumbersome. In order to deal with the above problems, an automatic powder spreading device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3An automatic powder spreading device comprises a spreading hopper 1, a head protrusion 5 is arranged inside the spreading hopper 1, a driving motor 18 is arranged inside the protrusion 5 through an equipment cavity 17, a rotating frame 6 is arranged inside the spreading hopper 1, a mounting frame 9 is arranged on the rotating frame 6, the mounting frame 9 is connected with the driving motor 18 through a synchronous mechanism, a T-shaped slide bar 11 is slidably penetrated through the mounting frame 9 through an elastic mechanism, an annular groove 13 is arranged on the arc-shaped outer wall of the spreading hopper 1, a mounting plate 14 is arranged on the rotating frame 6, a stirring shaft 15 is rotatably arranged on the mounting plate 14, a plurality of stirring rods 16 are arranged on the outer wall of the stirring shaft 15, and the stirring shaft 15 is connected with the protrusion 5 through a transmission mechanism.

[0021] The synchronization mechanism includes a synchronization shaft 10 which is rotatably arranged on the upper end surface of the protrusion 5 and connected to the output shaft of the driving motor 18. A synchronization hole corresponding to the synchronization shaft 10 is opened on the mounting frame 9. The top view structural schematic diagrams of the synchronization shaft 10 and the synchronization hole are both regular hexagons. The above-mentioned shape and structure not only facilitates the movement and separation of the two, but also when the driving motor 18 rotates, the synchronization shaft 10, the mounting frame 9 and the rotating frame 6 can rotate synchronously.

[0022] The elastic mechanism includes a spring 12 which is sleeved on the outside of the T-shaped slide bar 11, and the two ends of the spring 12 are elastically connected to the outer wall of the head of the T-shaped slide bar 11 and the outer wall of the mounting frame 9 respectively. The elastic potential energy provided by the spring 12 realizes the dragging operation of the head of the T-shaped slide bar 11, ensuring that the end of the T-shaped slide bar 11 is in the annular groove 13, thereby preventing the rotating frame 6 from vertically separating from the spreading hopper 1.

[0023] The transmission mechanism includes a gear 7 which is rotatably set on the upper end surface of the mounting plate 14 and fixedly connected to the stirring shaft 15. A gear ring 8 which meshes with the gear 7 is provided on the upper end surface of the protrusion 5. When the gear 7 rotates in the hopper 1 following the rotating frame 6, the gear ring 8 which is fixedly set will rotate, thereby driving the stirring shaft 15 and the stirring rod 16 to rotate synchronously.

[0024] The rotating frame 6 divides the spreading hopper 1 into six areas, wherein the inner bottom walls of three areas are provided with spreading holes 19. The three areas without the spreading holes 19 initially have silicon powder on each other, and the stirring shaft 15 and the stirring rod 16 are also in the area.

[0025] A plurality of supporting legs 2 are fixedly provided on the outer wall of the spreading hopper 1, and universal wheels 3 and handles 4 are provided on the plurality of supporting legs 2. The supporting legs 2 cooperate with the universal wheels 3 to support and conveniently move the spreading hopper 1. A locking assembly is provided on the universal wheels 3 to ensure the position stability when the device as a whole is moved to the destination, and the handles 4 facilitate dragging the device as a whole to move it.

[0026] When the utility model is used, the silicon powder is in three areas in the hopper 1. When the powder is spread, the drive motor 18 is started and rotated slowly. The drive motor 18 drives the rotating frame 6 to rotate in the hopper 1 with the help of the synchronous shaft 10 and the mounting frame 9, and pushes the silicon powder in the three areas to the other three areas. The powder spreading operation is realized through the spreading holes 19 in the three areas. In the process, the gear 7 cooperates with the gear ring 8 to rotate, so that the stirring shaft 15 can be driven to rotate. When the stirring shaft 15 rotates, the stirring rod 16 on its outer wall can realize the stirring treatment of the silicon powder in the area, ensuring the smoothness of its falling through the spreading hole 19.

[0027] After the silicon powder is scattered and the rotating frame 6 needs to be cleaned, first drag the T-shaped slide bar 11 to disengage its end from the annular groove 13, then lift the mounting frame 9 to disengage it from the hopper 1, and then take it down for easy cleaning.

[0028] 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.
