AI Technical Summary
During storage and transportation, powder materials are prone to arching due to the friction and cohesive forces between particles, which can lead to poor material discharge, affect production efficiency, and potentially cause equipment failure.
A powder arch-breaking device is adopted, including an elastic part and a rotating part. The rotating part is driven by a main motor to rotate around the axis of the powder storage device. The arch balance is broken by the deformation and recovery process when the protrusion comes into contact with the elastic part. At the same time, a beater rod and a drive mechanism are used to drive the beater rod to swing, further agitating the material and ensuring smooth flow of the powder.
It effectively breaks the arched balance in the powder, ensuring smooth flow of the powder in the storage device, avoiding adhesion, and improving production efficiency and equipment operation stability.

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0013] Example 1, such as Figure 1 As shown, the structure of this embodiment is as follows: a powder arch-breaking device, which includes an elastic part 2 disposed in a powder storage device 1. The elastic part 2 is arranged in a ring, and the upper and lower ends of the elastic part 2 are fixedly connected to the inner wall of the powder storage device 1 by bolts or the like. At this time, a cavity is formed between the middle part of the elastic part 2 and the inner side wall of the powder storage device 1. A rotating part 3 concentric with the powder storage device 1 is disposed on the side wall of the powder storage device 1. The upper and lower ends of the rotating part 3 are connected to the side wall of the powder storage device 1 by bearings. The powder storage device 1 above and below the rotating part 3 is connected by a protective shell. An external gear is disposed on the outer side wall of the rotating part 3. The external gear meshes with the drive gear on the outer side of the powder storage device 1. The drive gear is disposed on the output shaft of the main motor 4. By placing the main motor 4 externally, the convenience of maintenance is improved.
[0014] The rotating part 3 is provided with a protrusion 5 extending into the powder storage device 1. The protrusion 5 is an arc shape with the center facing outward. The distance between the inner wall of the protrusion 5 and the axis of the powder storage device 1 is less than the distance between the inner wall of the rotating part 3 and the axis of the powder storage device 1. The radial dimension of the protrusion 5 along the powder storage device 1 is greater than the radial dimension of the cavity along the powder storage device 1 without any external force. The elastic part 2 can be made of rubber or the like. The rotating part 3 is disposed between the side wall of the powder storage device 1 and the elastic part 2.
[0015] Specific working process: The main motor 4 drives the rotating part 3 to rotate around the powder storage device 1. Since the protrusion 5 extends inward into the powder storage device 1, when the protrusion 5 contacts a certain area of the elastic part 2, it will cause that area to move inward into the powder storage device 1. When the protrusion 5 moves away from that area, that area moves outward from the powder storage device 1. This movement causes different areas of the elastic part to vibrate, thereby breaking the arched balance in the powder, making the powder loose, and ensuring smooth flow of the powder within the powder storage device.
[0016] Example 2, as Figure 1 As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1. However, in this embodiment, the powder breaking device also includes a striking rod 6. Multiple striking rods 6 are arranged in a circular array around the axis of the powder storage device 1. The upper end of the striking rod 6 is rotatably disposed inside the powder storage device 1. For this purpose, a protective cover 11 is provided on the inner wall of the powder storage device 1. The lower end of the protective cover 11 is open. A rotating shaft is arranged horizontally inside the protective cover 11. The upper end of the striking rod 6 is disposed on the rotating shaft. The lower end of the striking rod 6 extends downward to the inner side of the elastic part 2. The lower end of the striking rod 6 rotates around its upper end rotating connection under the drive of the driving mechanism.
[0017] The driving mechanism includes a driving ring 7 concentric with the powder storage device 1. The installation method of the driving ring 7 is the same as that of the rotating part 3. A driven gear concentric with the driving ring 7 is provided on the outer wall of the driving ring 7. The driven gear meshes with the driving gear on the output shaft of the auxiliary motor 8 on the outer side of the powder storage device 1. A raised area 9 extending into the powder storage device 1 is provided on the side wall of the driving ring 7. The connection between the raised area 9 and other areas of the driving ring 7 is an arc transition. The contact area between the raised area 9 and the striking rod 6 is close to the upper end of the striking rod 6. A counterweight 10 is provided at the lower end of the striking rod 6. The counterweight 10 is arc-shaped, and its curvature matches the inner curvature of the elastic part 2.
[0018] Specific working process: the auxiliary motor 8 drives the driving ring 7 to rotate around the powder storage device 1. Since the convex area 9 extends to the inner side of the powder storage device 1, when the convex area 9 contacts the beating rod 6, the lower end of the beating rod 6 will swing to the inner side of the powder storage device 1, so as to generate a certain distance between the lower end of the beating rod 6 and the elastic part 2. When the convex area 9 is separated from the beating rod 6, the lower end of the beating rod 6 will swing to the elastic part 2, so as to beat the elastic part 2.
