[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figs. 1-5 This utility model provides a technical solution:

[0028] A high-efficiency dust removal and screening device includes a housing 1, with a feeding port fixedly installed on the upper side of the other side of the housing 1. The bottom side of the housing 1 is fixedly connected to a base plate 3 via a hinge 2. The device also includes a vibration assembly, which includes a rotating shaft 10. The rotating shaft 10 is rotatably mounted on the bottom of the base plate 3 via a rotating seat 11. Two sets of rotating wheels 12 are fixedly installed at both ends of the rotating shaft 10. The rotating wheels 12 are eccentrically arranged with the rotating shaft 10. Fixed rods 13 that cooperate with the rotating wheels 12 are fixedly installed on the bottom of both sides of the housing 1. A driven pulley 16 is fixedly installed in the middle of the rotating shaft 10. The driven pulley 16 is connected to a driving pulley 18 via a synchronous toothed belt 17. The driving pulley 18 is connected to the output end of a motor 19. The motor 19 is fixedly installed on the bottom of the base plate 3. A limit frame 20 is provided above the fixed rod 13. The limit frame 20 is fixedly connected to both sides of the base plate 3.

[0029] By rotatably connecting the box 1 to the bottom plate 3, it is easy to push the box 1 to rotate around the hinge 2, thereby achieving vibration of the box 1. By setting a motor 19, the output end of the motor 19 drives the active pulley 18, which drives the driven pulley 16 and the rotating shaft 10 to rotate via the synchronous toothed belt 17. This causes the eccentrically arranged rotating wheel 12 to periodically push the fixed rod 13 at the bottom of the box 1, thereby causing the box 1 to produce regular vibration. This vibration can promote the tea leaves to be evenly dispersed in the sieving frame 6, while accelerating the stratification and screening of tea leaves and impurities of different particle sizes, improving screening efficiency. By setting a limit frame 20, the upward movement range of the fixed rod 13 can be limited, thereby preventing the box 1 from overturning due to excessive rotation.

[0030] It also includes a screening assembly, which includes multiple sets of draw boxes 4. The draw boxes 4 are slidably installed in the draw slots 5 on one side of the housing 1. A screening frame 6 is inserted inside the draw box 4. Slide seats 7 are fixedly installed on both sides of the draw box 4. The slide seats 7 are slidably installed on the guide rods 8. A spring 9 for pushing the slide seats 7 to reset is slidably sleeved on the surface of the guide rods 8. Support plates 14 are provided on both sides of the bottom of the draw slots 5. The support plates 14 are fixedly connected to the housing 1. The support plates 14 abut against the bottom of the draw boxes 4 and slide with the draw boxes 4. One end of the guide rod 8 is fixedly connected to the inside of one side of the housing 1. The other end of the guide rod 8 is fixedly connected to the inside of the adjacent side of the housing 1 through the mounting plate 15. One end of the spring 9 abuts against the slide seat 7. The other end of the spring 9 abuts against the mounting plate 15.

[0031] By setting up a sieving component, impurities in Pu'er tea can be separated and graded. The coordinated design of multiple sets of drawers 4 and sieving frames 6 significantly improves sieving efficiency and maintenance convenience. The sieving frames 6 within the multiple drawers 4 have decreasing apertures from top to bottom. The bottommost sieving frame 6 has no openings at the bottom to collect fine impurities. After the tea leaves are added from the top of the box 1, they fall layer by layer under the action of the vibration component. Large plant debris is intercepted by the upper sieving frames 6, tea particles fall through the sieve holes into the middle sieving frames 6, and fine sand and debris fall into the bottommost sieving frame 6. This ultimately achieves stratified sieving of impurities and tea leaves, as well as different grades of tea, ensuring purity and... The grading accuracy is high; the drawer box 4 is slidably connected to the guide rod 8 via the slide 7, and the spring 9 provides the restoring force. The operator can directly pull out the drawer box 4 along the drawer groove 5, quickly remove the sieve frame 6 to clean the blocked tea leaves or impurities, and avoid the sieve holes being blocked, which would affect the sieving effect. After being released, the drawer box 4 can automatically return to the drawer groove 5. After sieving, the drawer box 4 can be pulled out and the sieve frame 6 can be pulled up to directly collect the graded tea leaves, simplifying the discharge process; the bottom of the drawer box 4 is supported by the support plate 14, which, together with the guide rod 8 and the slide 7, ensures the stability of the drawer box 4. The sieve frame 6 can be replaced as needed to adapt to the sieving requirements of different raw materials, improving the versatility of the equipment.

[0032] A dust removal assembly is installed on the top of the housing 1. The dust removal assembly includes a dust collection hood 21, which is fixedly installed on the top of the housing 1. The top of the dust collection hood 21 is fixedly connected to one side of the filter box 23 through a dust collection pipe 22. The filter box 23 is fixedly installed on the top of the dust collection hood 21. A fan 24 is installed on the other side of the dust collection hood 21. A filter screen is installed inside the dust collection hood 21.

[0033] By setting up a dust removal component, the dust collection hood 21, the fan 24 and the filter box 23 work together to quickly adsorb small impurities such as dust and lint from the tea leaves during the sieving process. After the fan 24 is started, it creates a negative pressure suction force, which draws the impurities raised inside the box 1 into the dust collection hood 21. The impurities and fine dust are transported to the filter box 23 for collection through the dust collection pipe 22. The continuous operation of the dust removal component can also effectively reduce dust in the working environment, which not only ensures the cleanliness of the tea leaves, but also improves the working environment of the operators.

[0034] In practical use, move the device to the designated position, first put the Pu'er tea to be processed into the feeding port of the box 1, start the motor 19, so that the rotating wheel 12 rotates eccentrically and pushes the bottom fixing rod 13 of the box 1, causing the box 1 to vibrate regularly, so that the tea leaves are evenly dispersed in the multi-component sieve frame 6 in the sieving component and are stratified. Large particles of impurities are intercepted by the upper sieve, while tea particles and fine impurities move downward through the sieve holes. At the same time, turn on the fan 24 of the dust removal component, and use the negative pressure suction in the dust collection hood 21 and the filter screen to suck in the dust, lint and other impurities raised during the sieving process and transport them to the filter box 23 for collection through the dust collection pipe 22. After the sieving is completed, pull out the drawer box 4 along the drawer 5, take out the sieving frame 6 to collect the graded tea leaves, clean the blockage impurities, and after cleaning, insert the sieving frame 6 back into the drawer box 4. Under the action of the spring 9, the drawer box 4 automatically slides back to its original position.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
