[0003] For some existing dust-free vibrating screens, in the way without a dispersion unit, the material to be screened is directly injected into the upper end of the screen mesh for material screening;

[0004] There are some problems with this traditional type of dust-free vibrating screen. For example, in the way without a dispersion unit, the screening efficiency of the material may be affected due to the accumulation of the material. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a dust-free vibrating screen, which can achieve efficient dispersion of materials before the screening work, and at the same time, the coarse and fine double-layer screen meshes effectively improve the vibration screening efficiency of the dust-free vibrating screen, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a dust-free vibrating screen, including a working bin and a dispersion mechanism;

[0007] Working bin: A second screening bin is arranged at the upper end thereof, a first screening bin is arranged at the upper end of the second screening bin, a feeding bin is connected to the upper end of the first screening bin through bolts evenly distributed, the lower end of the working bin is fixedly connected with telescopic columns evenly distributed, the fixed ends of the telescopic columns are fixedly connected with the upper ends of the support seats, and evenly distributed springs are fixedly connected between the support seats and the working bin, and the springs are all movably sleeved on the outer surfaces of the laterally adjacent telescopic columns;

[0008] Dispersion mechanism: It is evenly arranged in the middle of the inner wall of the feeding bin, which can achieve efficient dispersion of materials before the screening work, and at the same time, the coarse and fine double-layer screen meshes effectively improve the vibration screening efficiency of the dust-free vibrating screen.

[0009] Furthermore, a control switch is arranged at the right end of the support seat, and the input end of the control switch is electrically connected to an external power supply to control the vibration motor.

[0010] Furthermore, the dispersion mechanism includes a fixed seat, a fixed shaft, a torsion spring, a rotating seat and a dispersion plate. The fixed seats are evenly and fixedly connected to the middle of the inner wall of the feed bin. The fixed shafts are fixedly connected to the inside of the fixed seats. One end of each fixed shaft away from the fixed seat is rotatably connected to a rotating seat. One end of two horizontally adjacent rotating seats close to the center of the feed bin is fixedly connected to the same dispersion plate. The torsion springs are fixedly connected between the fixed seats and the horizontally adjacent rotating seats, and the torsion springs are movably sleeved on the outer surfaces of the vertically adjacent fixed shafts to achieve the dispersion of materials.

[0011] Furthermore, a feed pipe is arranged at the upper end of the feed bin. A guide plate is fixedly connected to the upper end inside the feed bin through evenly distributed support columns. The dispersion plates are all cooperatively installed with the guide plate to provide guidance for the injected materials.

[0012] Furthermore, an installation cylinder is fixedly connected to the inside of the working bin. A vibration motor is arranged inside the installation cylinder. The input end of the vibration motor is electrically connected to the output end of the control switch to provide driving force for the screening of materials.

[0013] Furthermore, a coarse sieve mesh is fixedly connected to the lower end of the first screening bin, a fine sieve mesh is fixedly connected to the lower end of the second screening bin, a discharge arc plate is fixedly connected to the upper end of the working bin, and discharge pipes are arranged at the right end of the first screening bin, the front end of the second screening bin and the rear end of the working bin to achieve double-layer screening of materials for coarse and fine particles.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: This dust-free vibrating screen has the following advantages:

[0016] Personnel control the operation of the vibration motor through a control switch. The mechanical force generated by the operation of the vibration motor causes the working bin to vibrate under the action of uniformly distributed springs and telescopic columns, thereby causing the discharge arc plate, fine screen, and coarse screen to vibrate. At the same time, personnel add materials into the interior of the feed bin through the feed pipe. The materials entering the interior of the feed bin first fall evenly to the upper ends of each dispersion plate under the guiding action of the guide plate. Under the action of the gravity of the materials, the dispersion plate rotates downward around the central axis of the laterally adjacent fixed shaft under the action of the laterally adjacent rotating seat. The downward rotation of the rotating seat causes the laterally adjacent torsion springs to hold special forces. When the gravity exerted by the materials on the dispersion plate is less than the torsion force of the torsion spring, the torsion force of the torsion spring causes the rotating seats to rotate upward, thereby realizing the upward rotation of the laterally adjacent dispersion plates, and further causing the dispersion plates to rotate up and down reciprocally with the change of force, thereby realizing the dispersion of the materials. The dispersed materials fall to the upper end of the vibrating coarse screen. The coarse screen roughly screens the materials, and the impurities screened out are removed through the discharge pipe at the right end of the first screening bin. The materials roughly screened fall to the upper end of the vibrating fine screen. The vibration of the fine screen realizes the fine screening of the materials, and the impurities screened out are removed through the discharge pipe at the front end of the second screening bin. The materials finely screened fall to the upper end of the vibrating discharge arc plate, and then are removed through the discharge pipe at the rear end of the working bin. It can realize the efficient dispersion of materials before the screening work, and at the same time, the double-layer coarse and fine screens effectively improve the vibration screening efficiency of the dust-free vibrating screen.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to Figures 1-3 , this embodiment provides a technical solution: a dust-free vibrating screen, including a working bin 1 and a dispersion mechanism 5;

[0023] Working bin 1: A second screening bin 2 is provided at its upper end, a first screening bin 3 is provided at the upper end of the second screening bin 2, a feed bin 4 is connected to the upper end of the first screening bin 3 by bolts evenly distributed, and evenly distributed telescopic columns 9 are fixedly connected to the lower end of the working bin 1. The fixed ends of the telescopic columns 9 are fixedly connected to the upper end of the support base 12. A plurality of springs 10 are fixedly connected between the support base 12 and the working bin 1. The springs 10 are all movably sleeved on the outer surface of the laterally adjacent telescopic columns 9. A control switch 16 is provided at the right end of the support base 12. The input end of the control switch 16 is electrically connected to an external power supply. An installation cylinder is fixedly connected inside the working bin 1, a vibration motor 11 is arranged inside the installation cylinder, and the input end of the vibration motor 11 is electrically connected to the output end of the control switch 16. A coarse screen 8 is fixedly connected to the lower end of the first screening bin 3, a fine screen 7 is fixedly connected to the lower end of the second screening bin 2, a discharge arc plate 6 is fixedly connected to the upper end of the working bin 1, and discharge pipes 13 are provided at the right end of the first screening bin 3, the front end of the second screening bin 2, and the rear end of the working bin 1. A plurality of moving wheels 15 are fixedly connected to the lower end of the support base 12. The control switch 16 enables the vibration motor 11 to operate. The mechanical force generated by the operation of the vibration motor 11 causes the working bin 1 to vibrate under the action of the evenly distributed springs 10 and telescopic columns 9, and then causes the discharge arc plate 6, the fine screen 7, and the coarse screen 8 to vibrate. The dispersed material falls onto the upper end of the vibrating coarse screen 8. The coarse screen 8 roughly screens the material, and the screened impurities are removed through the discharge pipe 13 at the right end of the first screening bin 3. The roughly screened material falls onto the upper end of the vibrating fine screen 7. The vibration of the fine screen 7 realizes the fine screening of the material, and the screened impurities are removed through the discharge pipe 13 at the front end of the second screening bin 2. The finely screened material falls onto the upper end of the vibrating discharge arc plate 6 and then is removed through the discharge pipe 13 at the rear end of the working bin 1. The screening process is completely carried out in a closed space, thereby realizing the dust-free screening of the material;

[0024] Dispersing mechanism 5: It is evenly arranged in the middle of the inner wall of the feed bin 4. The dispersing mechanism 5 includes a fixed seat 51, a fixed shaft 52, a torsion spring 53, a rotating seat 54 and a dispersing plate 55. The fixed seats 51 are evenly and fixedly connected to the middle of the inner wall of the feed bin 4. The fixed shafts 52 are fixedly connected to the inside of the fixed seats 51. One end of the fixed shaft 52 away from the fixed seat 51 is rotatably connected to a rotating seat 54. One end of two laterally adjacent rotating seats 54 close to the center of the feed bin 4 is fixedly connected to the same dispersing plate 55. The torsion springs 53 are fixedly connected between the fixed seat 51 and the laterally adjacent rotating seat 54. The torsion springs 53 are movably sleeved on the outer surface of the vertically adjacent fixed shafts 52. A feed pipe is arranged at the upper end of the feed bin 4. The upper end inside the feed bin 4 is fixedly connected with a guide plate 14 through evenly distributed support columns. The dispersing plates 55 are all installed in cooperation with the guide plate 14. Materials are added into the inside of the feed bin 4 through the feed pipe. The materials entering the inside of the feed bin 4 first fall evenly to the upper ends of the respective dispersing plates 51 under the guiding action of the guide plate 14. Under the action of the gravity of the materials, the dispersing plates 51 rotate downward around the central axis of the laterally adjacent fixed shafts 52 under the action of the laterally adjacent rotating seats 54. The downward rotation of the rotating seats 54 causes the laterally adjacent torsion springs 53 to hold a special force. When the gravity of the materials applied to the dispersing plates 51 is less than the torsion force of the torsion springs 53, the torsion force of the torsion springs 53 causes the rotating seats 54 to rotate upward, thereby realizing the upward rotation of the laterally adjacent dispersing plates 51, and further causing the dispersing plates 51 to rotate up and down reciprocally as the force changes, thereby realizing the dispersion of the materials.

[0025] The working principle of a dust-free vibrating screen provided by the present utility model is as follows: During operation, with the assistance of the moving wheels 15, the operator moves the dust-free vibrating screen to the required position. Then, the operator starts the operation of the vibrating motor 11 through the control switch 16. The mechanical force generated by the operation of the vibrating motor 11 causes the working bin 1 to vibrate under the action of the uniformly distributed springs 10 and telescopic columns 9, thereby causing the discharge arc plate 6, the fine screen 7, and the coarse screen 8 to vibrate. At the same time, the operator injects materials into the interior of the feed bin 4 through the feed pipe. The materials entering the interior of the feed bin 4 first fall evenly to the upper ends of the respective dispersion plates 51 under the guiding action of the guide plate 14. Under the action of the gravity of the materials, the dispersion plates 51 rotate downward around the central axis of the laterally adjacent fixed shaft 52 under the action of the laterally adjacent rotating seats 54. The downward rotation of the rotating seats 54 causes the laterally adjacent torsion springs 53 to hold special forces. When the gravity of the materials applied to the dispersion plates 51 is less than the torsion force of the torsion springs 53, the torsion force of the torsion springs 53 causes the rotating seats 54 to rotate upward, thereby causing the laterally adjacent dispersion plates 51 to rotate upward, and further causing the dispersion plates 51 to rotate up and down reciprocally with the change of the force received, thereby realizing the dispersion of the materials. The dispersed materials fall to the upper end of the vibrating coarse screen 8. The coarse screen 8 roughly screens the materials, and the screened impurities are removed through the discharge pipe 13 at the right end of the first screening bin 3. The roughly screened materials fall to the upper end of the vibrating fine screen 7. The vibration of the fine screen 7 realizes the fine screening of the materials, and the screened impurities are removed through the discharge pipe 13 at the front end of the second screening bin 2. The finely screened materials fall to the upper end of the vibrating discharge arc plate 6, and then are removed through the discharge pipe 13 at the rear end of the working bin 1. The screening process is completely carried out in a closed space, thereby realizing the dust-free screening of the materials.

[0026] It should be noted that, in the above embodiments, the vibrating motor 11 disclosed can be selected as the YZS-40-6 vibrating motor, and the control switch 16 is provided with a control button corresponding to the vibrating motor 11 and controlling its switch.

[0027] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
