Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screening devices, in particular to a vibrating screening device with adjustable aperture. Background Art

[0002] A vibrating screening device is a device used to screen granular or powdered materials, and separates raw materials into particles of different particle sizes through vibration force.

[0003] The publication number CN212664151U discloses a vibrating screening device, which includes a frame. A vibrating box is connected to the frame through springs. A vibrating motor is arranged on the vibrating box. A vibrating plate is arranged in the vibrating box. Screening holes are formed in the vibrating plate. A material receiving port is formed in one side of the vibrating box where the vibrating plate is located. A pushing assembly for pushing the screened material to the material receiving port is slidably arranged on the vibrating plate. After screening is completed in the utility model, the staff opens the switch door, and then uses the pushing assembly to push the remaining material after screening to the material receiving port, which helps to improve the efficiency of material cleaning and collection operations and reduces the manual labor intensity. Although this vibrating screening device has achieved the effect of improving the efficiency of material cleaning and collection operations, it lacks in adjusting the aperture of the screening plate. Since this screening device does not have a structure for adjusting the screening aperture, after screening out smaller materials, larger materials will remain in the screening box. If larger materials are to be taken out, they can only be taken out of the screening box manually, which not only increases the manual input but also reduces the working efficiency.

A jack 14 is opened on the surface of the screening plate B13, and the insertion bar 11 and the jack 14 are threadedly connected, and the threaded connection design of the insertion bar 11 and the jack 14 plays an effect of facilitating the fixed installation of the screening plate B13 in the screening plate A4.

[0027] Embodiment 2

[0028] Please refer to Figures 1-6 , a rotating rod 15 is rotatably connected inside the base 1, a guiding plate 16 is fixedly installed on the surface of the rotating rod 15, the number of the guiding plates 16 is two groups, and the two groups of guiding plates 16 are symmetrically distributed at both ends of the discharge port 7.

[0029] Working principle: When using the vibrating screening device, first pour the material to be screened into the screening box 2, and then turn on the vibrating motor 3. The vibrating motor 3 will drive the screening plate A4 to vibrate. When the screening plate A4 vibrates, it will drive the screening plate B13 to vibrate and also slide on the surface of the sliding rod 9. At this time, the smaller materials will pass through the screening holes and the screening plate B13 and fall into the collection box 8. When it is necessary to adjust the screening aperture, just rotate the insert 11. After the insert 11 is rotated out of the jack 14, the screening plate B13 can be pulled out of the slot 12.

The screening plate A4, the sieve holes 6, the vibrating motor 3, the sliding rod 9, the spring 10, the insert 11, the slot 12, the screening plate B13 and the jack 14 play the role of facilitating the disassembly and replacement of the screening plate A4 and the screening plate B13, thus achieving the effect of adjusting the screening aperture and avoiding the situation where larger materials need to be manually removed from the screening box 2. When the material is discharged from the screening box 2 through the discharge port 7, the material will pass through the guide plate 16. At this time, the guide plate 16 will guide the material. When the guide plate 16 is affected by gravity, it will rotate downward. At the same time, the guide plate 16 will also rotate upward under the torque action of the torsion spring 17, thus achieving the effect of protecting the material. The rotating rod 15, the torsion spring 17 and the guide plate 16 play the role of guiding the material when it is discharged through the discharge port 7 after screening, thus avoiding the situation where the material splashes out of the collection box 8 and also achieving the effect of buffering and protecting the falling of the material.
