[0023] Reference Figures 1 to 4 This utility model discloses a mineral powder storage device, comprising a storage bin 1, a discharge port 2 located at the center of the bottom of the storage bin 1, a screening mechanism 3 and a powder feeding mechanism 5 disposed on the bottom surface of the storage bin 1, the screening mechanism 3 comprising a first support plate 301, a screening frame 302 and a vibration motor 303, the powder feeding mechanism 5 comprising a second support plate 501, a first electric push rod 502, a receiving frame 503, a second electric push rod 504, a baffle 505, an extrusion plate 506 and a wire mesh 507, the screening frame 302 having an outlet on the side near the powder feeding mechanism 5, a first support leg 4 fixedly connected to the bottom surface of the storage bin 1, a discharge valve disposed in the discharge port 2, an inlet 7 disposed on the upper surface of the storage bin 1, and a cover plate 8 disposed on the upper surface of the inlet 7. The discharge valve in the discharge port 2 controls the outflow of mineral powder from the storage bin 1, and there are no sieve holes on the bottom surface at the outlet position of the screening frame 302.

[0024] The second support plate 501 is fixedly connected to the bottom surface of the discharge hopper. The second support plate 501 is L-shaped. The receiving frame 503 is fixedly connected to the upper surface of the horizontal part of the second support plate 501. The receiving frame 503 is inclined downward on the side away from the second support plate 501. The wire mesh 507 is fixedly connected at the junction of the horizontal part and the inclined part inside the receiving frame 503. The horizontal part inside the receiving frame 503 is directly below the outlet of the screening frame 302.

[0025] The extrusion plate 506 is slidably connected to the surface of the horizontal portion inside the receiving frame 503. The first electric push rod 502 is fixedly connected to the side surface of the vertical portion of the second support plate 501. The piston rod of the first electric push rod 502 passes through the side wall of the receiving frame 503 and is fixedly connected to the extrusion plate 506. The second electric push rod 504 is fixedly connected to the side surface of the vertical portion of the second support plate 501. The baffle 505 is fixedly connected to the piston rod of the second electric push rod 504. The position of the baffle 505 is directly opposite the outlet of the screening frame 302. Before the extrusion plate 506 pushes and extrudes the agglomerated mineral powder toward the wire mesh 507, the second electric push rod 504 drives the baffle 505 to move, blocking the outlet of the screening frame 302. After the extrusion plate 506 returns to its initial position, the second electric push rod 504 drives the baffle 505 to move again, releasing the blockage of the outlet of the screening frame 302.

[0026] The first support plate 301 is fixedly connected to the bottom surface of the storage bin 1. The first support plate 301 is L-shaped, with a through-hole in the middle of its horizontal section.

The screening frame 302 is directly below the discharge port 2. The vibration motor 303 is located on the side surface of the screening frame 302. The bottom of the screening frame 302 has sieve holes, and the lower inner surface of the screening frame 302 is inclined towards the direction of the discharge port. The vibration motor 303 drives the screening frame 302 to vibrate, causing the mineral powder to fall off and simultaneously causing the screened-out agglomerated mineral powder to slide towards the discharge port of the screening frame 302.

[0027] A material collection hopper 6 is provided below the storage bin 1. The material collection hopper 6 is located directly below the screening frame 302 and the receiving frame 503. The bottom surface of the material collection hopper 6 is fixedly connected to the second support leg 9.

[0028] Working principle: Mineral powder flows out from outlet 2 and falls into the screening frame 302 below. The powdery mineral powder falls from the sieve holes of the screening frame 302 into the collection hopper 6 below. The clumps of mineral powder slide towards the outlet of the screening frame 302 and eventually fall into the receiving frame 503. When a certain amount of clumps of mineral powder accumulates in the receiving frame 503, the second electric push rod 504 drives the baffle 505 to block the outlet of the screening frame 302. Then, the first electric push rod 502 drives the extrusion plate 506 to move, pushing and extruding the clumps of mineral powder towards the wire mesh 507, thereby pressing the clumps of mineral powder back into powder. Then, the extrusion plate 506 returns to its original position, and the second electric push rod 504 releases the blockage of the outlet of the screening frame 302.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
