[0019] Example 1

[0020] A bulk material device for cement mill includes a stabilizing bin 1. The shape and size of the stabilizing bin 1 can be determined according to actual conditions. A gate plate 2 is arranged in the stabilizing bin 1. After installation, the gate plate 2 can slide in the stabilizing bin 1, and the two sides of the gate plate 2 are in conflict with the inner wall of the stabilizing bin. When in use, materials can fall onto the gate plate 2. A support plate 3 is fixed to one side of the stabilizing bin 1, and a driving motor 4 is installed on the support plate 3. A threaded rod 5 is fixed to one end of the output shaft of the driving motor 4, and one end of the threaded rod 5 extends into the stabilizing bin 1 through one side of the stabilizing bin 1. A mounting seat 6 is fixed to the position of the gate plate 2 close to the driving motor 4, and the threaded rod 5 is threadedly connected to the mounting seat 6, and one end of the threaded rod 5 passes through the mounting seat 6. A baffle 7 is fixed to the side of the gate plate 2 away from the mounting seat 6. During operation, the threaded rod 5 can be driven to rotate forward and reverse by controlling the driving motor 4, thereby driving the gate plate 2 to reciprocate in the stabilizing bin 1, so as to homogenize the material on the gate plate 2, and make the homogenized material fall from one side of the gate plate 2 under the blocking action of the baffle 7. The reciprocating movement distance of the gate plate 2 can be ensured by controlling the forward and reverse time interval of the driving motor 4. In actual design, it can be ensured that all the materials fall onto the gate plate 2 and the threaded rod 5 does not separate from the mounting seat 6. A conveyor belt 8 is arranged below the flow stabilizing bin 1, and the materials falling through one side of the gate plate 2 can flow down along the side wall of the flow stabilizing bin 1 to the conveyor belt 8, and finally be transported by the conveyor belt 8 to the cement mill for grinding.

[0021] Example 2

[0022] On the basis of Example 1, a bulk material device for a cement mill, in order to achieve the movement stability of the gate plate 2, preferably, one end of the threaded rod 5 is also threadedly connected to the baffle 7, and after installation, there is a sufficient distance between the baffle 7 and the inner wall of the stabilizing chamber 1 for the threaded rod 5 to move.

[0023] On the basis of Example 1, a bulk material device for a cement mill, in order to further ensure the movement stability of the gate plate 2, preferably, limit shafts 9 arranged in pairs are fixed at the relative positions of the inner wall of the stabilizing bin 1, specifically, upper and lower rows of limit shafts 9 are arranged on the inner wall of the stabilizing bin 1, and the upper and lower limit shafts 9 are arranged in pairs, and roller bodies 10 are rotatably installed on the limit shafts 9. After installation, the two sides of the gate plate 2 are respectively located between the upper and lower rows of roller bodies 10. During the reciprocating operation of the gate plate 2, the roller bodies 10 also rotate accordingly, so as to ensure the smoothness of the movement of the gate plate 2 while limiting the position of the gate plate 2. The distance between the limit shaft 9 close to the baffle 7 and the baffle 7 is greater than the reciprocating distance of the gate plate 2. Therefore, the setting of the limit shaft 9 does not affect the normal movement of the gate plate 2.

[0024] On the basis of Example 1, a bulk material device for a cement mill, in order to protect the driving motor 4, preferably, a cover body 12 is fixed on the support plate 3 through a support rod 11, and the cover body 12 is located above the driving motor 4. The setting of the cover body 12 can prevent the driving motor 4 from being damaged by rain.

[0025] On the basis of Example 1, a bulk material device for a cement mill, in order to ensure the homogenization effect of the material and prevent the material from splashing from the top of the stabilizing bin 1, preferably, the gate plate 2 can be set in the stabilizing bin 1 at a distance of 1 meter from the top of the stabilizing bin 1.

[0026] On the basis of Example 1, in order to improve the convenience of design, a bulk material device for cement mill can preferably be configured with the support plate 3 and the flow stabilization chamber 1 as an integrated structure.

[0027] The utility model provides a bulk material device for cement mill, including a stabilizing bin 1, a gate plate 2 is arranged in the stabilizing bin 1, a driving motor 4 is fixed to one side of the stabilizing bin 1 through a support plate 3, a threaded rod 5 is fixed to one end of the output shaft of the driving motor 4, one end of the threaded rod 5 extends into the stabilizing bin 1 through one side of the stabilizing bin 1, a mounting seat 6 is fixed to the gate plate 2 near the driving motor 4, one end of the threaded rod 5 is arranged through the mounting seat 6, a baffle 7 is fixed to the side of the gate plate 2 away from the mounting seat 6, and when in use, in the process of materials continuously falling onto the gate plate 2, the driving motor 4 can be controlled by controlling the driving motor 4 to move the material to the stabilizing bin 1. The driving motor 4 rotates forward and reverse, driving the threaded rod 5 to rotate forward and reverse, and then driving the gate plate 2 to make reciprocating horizontal movements in the stabilizing bin 1, so as to achieve homogenization of the material on the gate plate 2. A conveyor belt 8 is arranged below the stabilizing bin 1. During the reciprocating movement of the gate plate 2, the material thereon can be blocked by the baffle 7 and fall onto the conveyor belt 8 through the other side of the gate plate 2, and finally be transported to the cement mill. The coordinated use of the gate plate 2, the threaded rod 5 and the driving motor 4 can achieve effective homogenization of the material entering the stabilizing bin 1, avoid material segregation, and ensure the normal production of cement.
