[0027] 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.

[0028] The screening equipment in this solution is used to screen Wuyi rock tea, thereby removing any debris that is attached to or mixed with the tea leaves.

[0029] like Figures 1-4 As shown, this utility model provides a technical solution: a screening device for making Wuyi rock tea, including a screening box 1 and a controller. To avoid the inconvenience of feeding materials due to the excessively high position of the feeding hopper in the prior art, and to reduce labor intensity, a tea feeding component 2 is provided on one side of the top of the screening box 1. As shown... Figure 4 The tea feeding component 2 includes a tea feeding enclosure 201, one side of which extends into the screening box 1. A conveyor 202 is provided inside the tea feeding enclosure 201. The conveyor 202 consists of a roller, a conveyor belt, and a drive motor. This is existing technology and will not be described in detail in this solution. After the drive motor is started, the roller drives the conveyor belt to rotate. A downwardly inclined screening plate 3 is provided inside the screening box 1. The tea leaves to be screened fall onto the top of the screening plate 3 through the tea feeding component 2. The screened rock tea fragments or impurities fall into the bottom of the screening box 1 through the screening holes of the screening plate 3. The rock tea fragments or impurities are collected by the fragment collection box 7 placed at the bottom of the screening box 1. After a period of time, the rock tea fragments or impurities in the fragment collection box 7 can be cleaned by opening the side plate 101 at the bottom of the screening box 1.

[0030] The screening plate 3 passes through the through groove 102 of the screening box 1. The screened rock tea is discharged from the screening box 1 through the discharge side of the screening plate 3. To facilitate the collection of rock tea, a tea collection box is placed at the bottom of the discharge side of the screening plate 3.

[0031] A dust outlet is provided on the side of the screening plate 3, and a dust removal device is installed outside the dust outlet to purify the air inside the screening box 1. Specifically, as shown in the figure... Figure 1 and Figure 2 As shown, the dust removal device includes an outlet pipe 403 and an inlet pipe 406. A filter box 405 is connected between the outlet pipe 403 and the inlet pipe 406. The dust generated during screening is filtered through the filter screen of the filter box 405. The filter box 405 is existing technology and will not be described in detail in this solution.

[0032] An air intake hood 401 that retracts outward is fixedly connected to the side of the dust outlet, and an air outlet pipe 403 is fixedly connected to the air intake hood 401. An air pump 404 is connected to the pipe body of the air outlet pipe 403. When the air pump 404 is turned on, a negative pressure is generated in the screening box 1 and the top of the tea inlet component 2, which can prevent the dust generated after screening from overflowing into the air through the channel 102 and the tea inlet component 2.

[0033] In this solution, in order to achieve rapid dust removal from the screening box 1, there are two dust outlets, which are distributed at the top and bottom of the screening plate 3. A drive assembly 5 is provided on the outside of the screening box 1. The drive assembly 5 drives the screening plate 3 to shake, so as to screen the tea leaves.

[0034] To provide stable support for the screening plate 3, L-shaped plates 601 are fixed on both sides of the through groove 102, and fixing plates 602 are fixed on both sides of the screening plate 3 extending out of the through groove 102. A guide rod 603 parallel to the screening plate 3 is fixed on the plate body of the fixing plate 602, and the guide rod 603 is movably inserted into the L-shaped plate 601. In this way, under the drive of the drive assembly 5 and the guidance of the guide rod 603, the screening plate 3 can be shaken.

[0035] like Figure 4 As shown, the drive assembly 5 includes a socket tube 501, which is fixedly connected to the air intake pipe 406. A rod 502 is movably inserted into one side of the socket tube 501. The rod 502 is fixed to the screening plate 3 by a fixed bracket. An exhaust pipe 503 is fixedly connected to one side of the socket tube 501. A solenoid valve 504 electrically connected to the controller is connected to the body of the exhaust pipe 503. A spring 505 is fixed between the rod 502 and the side wall of the socket tube 501.

[0036] As a supplement to this solution, when using this device, the controller controls the tea feeding assembly 2 and the air pump 404 to start. The worker places the rock tea to be screened on the conveyor belt on the tea feeding assembly 2. The rock tea to be screened falls onto the top of the screening plate 3 under the conveyor belt. The air in the screening box 1 enters the filter box 405 through the air outlet pipe 403 for filtration. The filtered air enters the socket pipe 501 through the air inlet pipe 406. Under the action of air pressure, the spring 505 extends and drives the screening plate 3 to move through the insertion rod 502. After the screening plate 3 moves to a certain distance, the controller controls the solenoid valve 504 to open, and the pressure in the socket pipe 501 is released through the exhaust pipe 503. After the pressure is released, the spring 505 returns to its original position, thereby driving the insertion rod 502 and the screening plate 3 to return to their original positions. In this way, the shaking of the screening plate 3 is achieved by continuously opening and closing the solenoid valve 504, thereby achieving the screening of rock tea. The screened rock tea is finally discharged from the screening box 1 through the discharge side of the screening plate 3.

[0037] 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 embodiments and their equivalents.
