AI Technical Summary
Existing quartz sand screening equipment suffers from low screening efficiency, easy material accumulation and blockage, and easy damage to the screen plate, resulting in increased motor load and high energy consumption.
The drive mechanism drives the movable frame to move the screen plate horizontally back and forth. Combined with the electric push rod driving the swing arm to rotate the U-shaped bent rod, the horizontal back and forth movement of the screen plate and the lifting of the front end of the screen plate are realized. This prevents large particles of quartz sand from directly impacting the screen plate and causing material accumulation. The screen plate quickly disperses the material and reduces the load on the screen plate.
It improves screening efficiency, prevents screen plate wear and material blockage, reduces motor energy consumption, saves manual labor intensity, and ensures uniform particle size after screening.

[0002] Quartz sand is obtained by crushing quartz particles, and there is great difference in its specifications. When it is used, it needs to be screened to ensure that the specifications of quartz sand are consistent. At present, when quartz sand is screened, quartz sand is divided into two types, one is inclined screen, and the other is horizontal screen. Among them, the inclined screen is a jumping and flowing screening, and the horizontal screen is a full-range jumping screening.

[0030] In this embodiment, referring to 1, 2, 3, the driving mechanism 3 comprises a mounting plate 31, a motor 32, a rotating disc 33, an eccentric shaft 34, a connecting rod 35, and a guide rod 36. The mounting plate 31 is horizontally arranged at the front end of the rectangular frame 11. The motor 32 is fixedly connected to the mounting plate 31 through a support. The rotating disc 33 is coaxially fixed to the output shaft of the motor 32. The eccentric shaft 34 is eccentrically arranged at the outer end of the rotating disc 33. The eccentric shaft 34 is vertically rotatably connected to the front end of the connecting rod 35. The rotating disc 33 drives the eccentric shaft 34 to eccentrically rotate. The eccentric shaft 34 drives the connecting rod 35 to move back and forth and swing up and down. Specifically, the connecting rod 35 is provided with a pivot hole. The eccentric shaft 34 is sleeved in the pivot hole. The outer end of the eccentric shaft 34 is provided with external threads and connected with a nut for limiting.

[0032] In this embodiment, further, two rotating shafts 141 are perpendicularly arranged at the two side walls of the rear end of the sieve plate 14. Specifically, the one end of each rotating shaft 141 is fixedly connected to the side wall of the sieve plate 14 through the external threads arranged on the outer wall. The sieve plate 14 is rotatably connected to the rotating shaft holes arranged in the inner side walls of the two longitudinal beams of the movable frame 13 through the two rotating shafts 141, respectively. Each rotating shaft hole penetrates through the two side walls of the longitudinal beam of the movable frame 13. The sieve plate 14 can be rotated relative to the movable frame 13 through the two rotating shafts 141 to lift the front end. The quartz sand that cannot pass through the sieve plate 14 is unloaded to the first material receiving groove 16 along the inclined surface of the sieve plate 14, preventing the horizontal material screening from being affected.
[0033] Further, in the embodiment, the first receiving groove 16 fixedly connected with the supporting leg 12 is arranged below the sieve plate 14, and the first receiving groove 16 is used for receiving undersize materials.
[0034] Further, in the embodiment, the two positioning plates 19 arranged at the bottom of the movable frame 13 are arranged at the front end of the sieve plate 14, so that the front end of the sieve plate 14 can only rotate upward and cannot be displaced downward, thereby ensuring that the sieve plate 14 moves horizontally and reciprocally during the sieving process.
[0035] As can be seen from the above technical scheme, in use, first, the quartz sand is added into the sieving box 2 through the feeding hopper 21, and the quartz sand enters the sieve plate 14 in the sieving box 2 through the feeding opening. Meanwhile, the controller controls the motor 32 to drive the rotating disc 33 to rotate, and the eccentric shaft 34 is driven to rotate eccentrically, and the connecting rod 35 is driven to move reciprocally and swing up and down, and the connecting rod 35 drives the movable frame 13 to move reciprocally along the horizontal direction, so that the materials on the sieve plate 14 are dispersed and sieved, and the undersize materials enter the first receiving groove 16. When the materials that cannot pass through the sieve on the sieve plate 14 are too much, the feeding is stopped, and the sieve plate 14 is driven to the last end of the stroke of the guide groove 111 of the rectangular frame 11, so that the rear end of the sieve plate 14 is located above the guide groove 17. The electric push rod 44 is controlled to drive the swing rod 43 to rotate, and the U-shaped bent rod 4 is driven to lift the front end of the sieve plate 14, so that the oversize materials on the sieve plate 14 slide from the rear end of the sieve plate 14 to the guide groove 17, and then enter the second receiving groove 18. After the oversize materials are unloaded, the electric push rod 44 is controlled to drive the sieve plate 14 to rotate to the horizontal state, and then the quartz sand is continuously added into the sieving box 2 through the feeding hopper 21 to be sieved.
