[0023] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While example embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.
[0024] As Figures 1 to 7As shown, a new screening device, including a rack 1, the top surface of the rack 1 is an inclined downward installation surface, the included angle between the installation surface and the horizontal plane is 30-35°, the installation surface is sequentially provided with a feeding screen 2, a first vibrating screen 3 and a second vibrating screen 4 from top to bottom, corresponding to the feeding screen 2 and the second vibrating screen 4, a first vibrating motor 5 is installed on the rack 1, and a second vibrating motor 6 is symmetrically installed on the first vibrating screen 3 and the second vibrating screen 4.
[0025] In work, the material is transported to the feeding screen 2 by the excavator or the conveying belt, and the material is continuously vibrated downward to the first vibrating screen 3 and the second vibrating screen 4 by the action of the first vibrating motor 5, since the second vibrating motor 6 is installed on the first vibrating screen 3 and the second vibrating screen 4, the first vibrating screen 3 and the second vibrating screen 4 can fully vibrate, thereby improving the screening effect and efficiency, and since the second vibrating motor 6 on the first vibrating screen 3 and the second vibrating screen 4 is designed to be left-right symmetrical, the material is not easy to accumulate in the middle position, and the material will be dispersed by vibration.
[0026] The rack 1 is a frame body spliced by fasteners, which has low cost, fast installation and disassembly, no site limitation, low labor requirement and convenient overall device transfer.
[0027] In the embodiment, the four edges of the feeding screen 2 are fixed on the rack 1, and the front ends of the first vibrating screen 3 and the second vibrating screen 4 are fixed on the rack 1, and the remaining edges are not fixed. This structure design makes the first vibrating screen 3 and the second vibrating screen 4 have only one end fixed, and the remaining ends are free, so that when the second vibrating motor 6 works, it can vibrate more fully.
[0028] In the embodiment, the rack 1 is provided with a fixed plate 7, the first vibrating motor 5 is fixedly arranged on the fixed plate 7, the top surface mounting plate 8 and the bottom surface mounting plate 9 are correspondingly arranged on the top surface and the bottom surface of the first vibrating screen 3 and the second vibrating screen 4, the top surface mounting plate 8 and the bottom surface mounting plate 9 are fixedly connected by bolts, and the second vibrating motor 6 is fixedly arranged on the bottom surface of the bottom surface mounting plate 9. The second vibrating motor 6 is connected with the first vibrating screen 3 and the second vibrating screen 4 through the top surface mounting plate 8 and the bottom surface mounting plate 9, so that the first vibrating screen 3 and the second vibrating screen 4 can fully vibrate when the second vibrating motor 6 works, which is beneficial to improve the screening effect and efficiency.
[0029] In the embodiment, the elastic protection pad 10 is arranged on the rack 1 corresponding to the bottom surface mounting plate 9. When the second vibrating motor 6 works, the bottom surface mounting plate 9 vibrates up and down, the elastic protection pad 10 contacts and collides with the bottom surface mounting plate 9, avoiding the direct collision of the bottom surface mounting plate 9 with the rack 1, which is beneficial to protect the structure and prolong the service life.
[0030] In the embodiment, the first vibrating screen 3 and the second vibrating screen 4 are uniformly provided with the dispersion assembly 11 around. The dispersion assembly 11 comprises a top plate 111 and a bottom plate 112, which are fixedly connected into an integrated body by bolts 113 and correspondingly arranged on the top surface and the bottom surface of the first vibrating screen 3 and the second vibrating screen 4. The bottom plate 112 and the top plate 111 are both circular thin plates. The dispersion assembly 11 can reinforce the connection area of the second vibrating motor 6 and the first vibrating screen 3 and the second vibrating screen 4, so that the screen surface is not easy to be broken. On the other hand, the vibration generated by the second vibrating motor 6 can be fully transmitted to the whole screen surface, so as to improve the screening effect.
[0031] In the embodiment, the rack 1 is further provided with a screen cleaning assembly. The screen cleaning assembly comprises a base plate 12, a screen cleaning motor 13 and a rotating shaft 14. The base plate 12 is fixed on the rack 1, the screen cleaning motor 13 is installed on the base plate 12, one end of the rotating shaft 14 is connected to the output end of the screen cleaning motor 13, and the other end of the rotating shaft 14 is symmetrically provided with a rubber strip 15. The screen cleaning assembly can clean the material adhered to the screen surface, so that the screen surface always maintains good passability, and the screening effect is improved.
[0032] Three pairs of screen cleaning assemblies are arranged on the rack 1 on both sides of the feeding screen 2, the first vibrating screen 3 and the second vibrating screen 4. Meanwhile, a plurality of spray nozzles (not shown in the figure) can be arranged on both sides of the rack 1 corresponding to the feeding screen 2, the first vibrating screen 3 and the second vibrating screen 4, and the active agent can be sprayed to the screen surface through the spray nozzles. The screen cleaning motor 13 drives the rotating shaft 14 to rotate clockwise and counterclockwise alternately, so as to drive the rubber strip 15 to repeatedly beat the screen surface, so that the material adhered to the screen surface is beaten off, and the screen surface is cleaned.
[0033] The utility model can effectively solve the phenomenon that the material is accumulated on the screen, and improve the screening effect and efficiency.
