DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings.

[0026] As Figures 1-7 shown, a new type of vibrating screening machine includes a screening machine housing 1. The interior of the screening machine housing 1 is sequentially divided into a feeding operation area 2, a vibrating material distribution area 3, and a power source installation area 4 from top to bottom; the feeding operation area 1 includes a feeding port 5 and a dust removal port 6 located above the screening machine housing 1; the vibrating material distribution area 3 includes a vibrating screening plate 7 inclined below the feeding port 5. The lower end of the vibrating screening plate 7 is communicated with a low-density material port 8, and the upper end of the vibrating screening plate 7 is communicated with a high-density material port 9. Both the low-density material port 8 and the high-density material port 9 are fixedly arranged on the screening machine housing 1. A vibration transfer plate 10 is fixedly arranged at the lower end of the vibrating screening plate 7, and an air flow dispersion mechanism 11 is fixedly arranged on the vibration transfer plate 10; the power source installation area 4 includes a vibration mechanism 12 for providing vibration force to the vibrating material distribution area 3 and a blowing mechanism 13 for providing air flow to the vibrating material distribution area 3.

[0027] The vibrating screening machine of the present utility model is sequentially divided into a feeding operation area 2, a vibrating material distribution area 3, and a power source installation area 4 from top to bottom. The equipment structure has clear functional partitions, high integration, and a small floor area of the equipment; at the same time, the vibration mechanism 12 provides vibration force to each structure in the vibrating material distribution area 3, and the blowing mechanism 13 provides air flow. In combination with the air flow dispersion mechanism 11, the air flow is dispersed onto the vibrating screening plate 7, separating the high-density materials and low-density materials in the materials on the vibrating screening plate 7 and discharging them from different outlets, effectively improving the screening effect and screening efficiency.

[0028] Further, the vibrating screening plate 7 includes a screening plate body 14. A plurality of air holes 15 are arranged on the screening plate body 14, and a fixing plate 16 for bolt connection with the inner wall of the screening machine housing 1 is arranged at the lower end of the screening plate body 14.

[0029] Specifically, the vibrating screening plate 7 is bolt-connected to the inner wall of the screening machine housing 1 through the fixing plate 16. The connection structure is simple, facilitating the replacement or repair of the vibrating screening plate 7. In addition, the diameter of the air holes 15 on the vibrating screening plate 7 is set to 0.4 mm, which can effectively prevent materials from falling in the air holes 15 while facilitating the passage of air flow.

[0030] Further, the air flow dispersion mechanism 11 includes parallel connecting rods 17, a first V-shaped diversion plate 18 fixedly arranged at the upper ends of the two connecting rods 17, and a second V-shaped diversion plate 19 fixedly arranged at the lower ends of the two connecting rods 17. The first V-shaped diversion plate 18 and the second V-shaped diversion plate 19 are arranged in an alternating manner, and a first threaded hole 20 for threaded connection with the vibration transfer plate 10 is arranged on the connecting rod 17.

[0031] Specifically, the air flow dispersion mechanism 11 is fixedly arranged below the vibrating screening plate 7 and above the air blowing mechanism 13 through the first threaded hole 20. When the air blowing mechanism 13 blows air onto the diversion plate, since the diversion plate is of a V-shaped structure, it can disperse the air flow well. And by arranging the V-shaped diversion plates staggered up and down, the dispersion effect of the air flow is improved, and the vibrating screening plate 7 can be better provided with air flow, so that the vibrating screening plate 7 realizes material separation under the dual action of vibration and air flow, and the screening effect is improved.

[0032] Furthermore, the vibration mechanism 12 includes a driving motor 21 fixedly arranged at the bottom of the vibration source installation area 3. A first pulley 22 is fixedly arranged on the output shaft of the driving motor 21. The first pulley 22 is connected to a second pulley 24 through a belt 23. The second pulley 24 is fixedly arranged on a rotating shaft 25. Both sides of the rotating shaft 25 are rotatably connected in the vibration source installation area 3 through bearing seats 26. A plurality of cams 27 are arranged in parallel on the rotating shaft 25. A transmission rib plate 28 is fixedly arranged below the vibration transmission plate 10. A transmission rod 29 is fixedly arranged on the transmission rib plate 28. The free end of the transmission rod 29 is in contact connection with the cam 27 through a vibration block 30.

[0033] Specifically, the working process of the vibration mechanism is as follows: The driving motor 21 drives the first pulley 22 and the second pulley 24 to rotate through the belt 23, thereby driving the rotating shaft 25 to rotate. Since a plurality of cams 27 are arranged on the rotating shaft 25, the cams 27 rotate accordingly under the drive of the rotating shaft 25. The cams 27 are in contact with the vibration blocks 30, so that the vibration blocks 30 vibrate along with the structural trajectory of the cams 27. Thus, the vibration transmission plate 10 is driven to vibrate through the transmission rod 29 and the transmission rib plate 28. Then, the vibration transmission plate 10 drives each structure in the vibration material distribution area 3 to vibrate, including the vibrating screening plate 7, the discharge port, the air flow dispersion mechanism 11, etc.

[0034] Furthermore, the air blowing mechanism 13 includes a fan 31, a fan motor 32 belt-connected to the fan 31, and a hose 33 fixedly arranged at the air outlet of the fan. The other end of the hose 33 penetrates through the vibration transmission plate 10 and is located below the air flow dispersion mechanism 11.

[0035] Specifically, the fan motor 32 drives the fan 31 to rotate through a belt to provide air flow, and the air flow is transmitted to the lower part of the air flow dispersion mechanism 11 through the hose 33.

[0036] Further, an output amount adjusting mechanism is provided on one side of the vibration screening plate 7 at the high-density material outlet 9. The output amount adjusting mechanism includes a fixing plate 34 fixedly arranged on the inner wall of the screening machine housing 1. A regulating plate 35 is rotatably connected to the fixing plate 34. A through second threaded hole (not shown) is provided on the regulating plate 35. A regulating rod 36 is threadedly connected in the second threaded hole. A stop block 37 is fixedly arranged on the regulating rod 36. The regulating rod below the stop block 37 is a threaded rod. The free end of the threaded rod penetrates through an elastic strip 38 and is threadedly connected to the second threaded hole. The other end of the elastic strip 38 is fixedly connected to the fixing plate 34.

[0037] Specifically, an output amount adjusting mechanism is provided at the high-density material outlet 9, which can effectively control the discharge amount of the material, enabling the material to be fully vibration-separated and improving the screening effect. The specific adjustment process is as follows: First, through the stop block 37 and elastic strip 38 structure, the regulating rod 36 can be fixed above the regulating plate 35, and the threaded rod structure below the regulating rod 36 is connected to the second threaded hole on the regulating plate 35. By rotating the regulating rod 36, the gap size between the regulating plate 35 and the vibration screening plate 7 is controlled, thereby adjusting the discharge amount.

[0038] Further, a micro-residual material discharge pipe 39 is provided on one side of the vibration transfer plate 10 close to the air flow dispersion mechanism 11. The discharge port of the micro-residual material discharge pipe 39 is located inside the high-density material outlet 9.

[0039] Specifically, since air holes 15 are provided on the vibration screening plate 7, some fine powder materials will fall onto the vibration transfer plate 10 through the air holes 15 by vibration. Therefore, when cleaning the equipment after vibration screening is completed, these fine powder materials are discharged through the micro-residual material discharge pipe 39. Since a maintenance door is provided on the side of the screening machine housing 1, after the equipment stops, the maintenance door can be directly opened to manually clean the fine powder materials, and the discharge port is arranged inside the high-density material outlet 9, improving the integration of the equipment.

[0040] Further, an L-shaped vibration material distributing plate 40 is provided below the feed inlet 5. The L-shaped vibration material distributing plate 40 is fixedly arranged on the inner wall of the screening machine housing 1 in the vibration material distribution area 3. After the material enters from the feed inlet 5, it falls onto the L-shaped vibration material distributing plate 40, and the material is evenly scattered on the vibration screening plate 7 through vibration, effectively preventing the material from accumulating at the feed inlet and improving the screening efficiency. At the same time, a baffle plate 41 is provided on the side opposite to the outlet of the L-shaped vibration material distributing plate 40. The upper end of the baffle plate 41 is fixedly arranged on the inner wall of the screening machine housing 1 in the feed operation area 2. The baffle plate 41 makes all the fed materials fall on the vibration screening plate 7, effectively preventing the fed materials from entering the discharge port without being screened and affecting the screening effect.

[0041] Furthermore, an observation window 42 is provided on the screening machine housing 1 on one side of the feed inlet 5, through which the screening situation of the materials inside the equipment can be observed in real time.

[0042] The working process of the present utility model is as follows: First, start the drive motor and the fan motor to activate the vibration mechanism and the blowing mechanism of the equipment. Then, put the material to be separated into the feed inlet. The material is evenly scattered on the vibrating screening plate by the L-shaped vibrating material distributor. After vibration and air blowing on the vibrating screening plate, separation is achieved, so that the low-density material is discharged from the low-density material outlet, and the high-density material is discharged from the high-density material outlet, realizing the separation of the materials. At the same time, a dust removal device is connected to the dust removal port, and the fine dust generated during the operation of the equipment is discharged from the dust removal port. In addition, for the fine powder material that enters the vibration transfer plate through the air holes, after the separation is completed, the maintenance door can be opened for manual cleaning, so that the material is discharged at the small residual material discharge pipe.

[0043] The above has described in detail an embodiment of the present utility model, but the content described is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
