When the rotating rod 42 rotates, it drives the plurality of groups of turning rods 43 to flip and turn the tea leaves, so that the tea leaves passing through the position of the turning component 4 are in a thin layer, preventing the tea leaves from piling up together and affecting the impurity removal effect.
[0040] Furthermore, a guiding hopper 5 for guiding the tea leaves is installed on the top of the electric conveyor belt 2 to prevent the tea leaves from falling outside the device. A transition plate 51 is provided below the guiding hopper 5, and a third vibrating plate 52 is installed at the bottom of the transition plate 51. The third vibrating plate 52 is fixed on the frame. The third vibrating plate 52 drives the transition plate 51 to vibrate so that the tea leaves move uniformly towards the impurity removal plate 31.
[0041] Specifically, please refer to Figure 2 and Figure 3, the above impurity removal device further includes an impurity removal mechanism 3 disposed on the side of the electric conveyor belt 2 away from the temporary storage hopper 1 for multi-stage impurity removal of tea leaves. The impurity removal mechanism 3 includes an impurity removal plate 31, a second vibrating disk 32, and an electrostatic roller 33. A plurality of groups of second vibrating disks 32 are installed at the bottom of the impurity removal plate 31.

The impurity removal plate 31 is inclined, so that the tea leaves on the impurity removal plate 31 move. A plurality of groups of electrostatic rollers 33 are arranged at the top of the impurity removal plate 31 for adsorbing dust impurities.

[0042] A discharge plate 8 is arranged on the side of the impurity removal plate 31 away from the electric conveyor belt 2. The discharge plate 8 is installed on the machine frame, which is convenient for the centralized discharge of the tea leaves after impurity removal is completed.
[0043] Furthermore, as Figure 1 , Figure 3 and Figure 4As shown in the figure, the above-mentioned impurity removal device further includes an ash discharging assembly 6 for removing impurities adsorbed on the static electricity roller 33. The ash discharging assembly 6 includes a mounting plate 61, a first vibration motor 62, a guide groove 63, and a scraper 64.

At least one group of first vibration motors 62 is installed on the top of the mounting plate 61. A guide groove 63 is arranged on the first vibration motor 62. The bottom of the guide groove 63 is inclined away from the first servo motor 35. The first vibration motor 62 is used to drive the guide groove 63 to vibrate, so that the dust in the guide groove 63 can move and be discharged along the inclined plane at the bottom of the guide groove 63. A scraper 64 arranged obliquely is installed on one side of the guide groove 63 close to a corresponding group of scrapers 64.

The discharge ports of multiple groups of guide grooves 63 are all located above the centralized trough 66, and the dust in multiple groups of guide grooves 63 is concentrated in the centralized trough 66 for centralized treatment. An ash discharging hopper 67 is further arranged at the end of the centralized trough 66, facilitating the centralized discharge of dust and impurities.
[0044] Finally, please refer to Figures 3 - 5 As shown in the figure, the above-mentioned impurity removal device further includes an elastic mechanism 7 for driving the scraper 64 to approach the static electricity roller 33. The elastic mechanism 7 includes a limit block 71, a chute 72, a fixing plate 73, a connecting rod 74, a spring 75, and a limit disc 76. Multiple groups of limit blocks 71 are installed on the side of the side plate 34 close to the mounting plate 61. Chutes 72 cooperating with the limit blocks 71 are opened at both ends of each group of mounting plates 61, facilitating the stable movement of the mounting plate 61 under the limiting action of the limit blocks 71. A fixing plate 73 installed on the side surface of the side plate 34 is arranged on one side of each group of guide grooves 63 away from the static electricity roller 33. The fixing plate 73 is L-shaped. Multiple groups of connecting rods 74 are slidably connected in the fixing plate 73. One end of the connecting rod 74 is fixedly connected to the guide groove 63. A spring 75 arranged between the guide groove 63 and the fixing plate 73 is sleeved on the outer circle of the connecting rod 74. The end of the connecting rod 74 away from the guide groove 63 is fixedly connected to a limit disc 76, enabling the spring 75 to release elastic force to drive the scraper 64 to approach the static electricity roller 33, ensuring that the scraper 64 can scrape off the impurities and dust on the static electricity roller 33.
[0045] The first vibrating tray 12, the impurity removal plate 31, and the third vibrating tray 52 are all flexible vibrating trays, and their surfaces will generate periodic vibrations. This kind of vibration can make the tea leaves move on the surface, which is the prior art and will not be elaborated here.
[0046] In this embodiment, first, the tea leaves are centrally placed in the temporary storage hopper 1. The tea leaves fall on the temporary storage plate 11. The first vibrating tray 12 starts to drive the tea leaves to move uniformly onto the electric conveyor belt 2, and the electric conveyor belt 2 drives the tea leaves to rise upward. At the same time, the second servo motor 41 starts to drive the rotating rod 42 to rotate, so that multiple turning rods 43 rotate, making the thickness of the tea leaves passing through the position of the rotating rod 42 uniform. Then the tea leaves are discharged from the top of the electric conveyor belt 2 to the transition plate 51 through the guidance of the guiding hopper 5. After the third vibrating tray 52 starts, it drives the transition plate 51 to vibrate, and at the same time, the tea leaves on it move in the direction away from the electric conveyor belt 2 to the impurity removal plate 31. After the second vibrating tray 32 starts, it drives the impurity removal plate 31 to vibrate and at the same time the tea leaves on it move towards the discharging plate 8. At the same time, the first servo motor 35 drives the static roller 33 to rotate. When the dust and impurities pass under the static roller 33, they are adsorbed onto the surface of the static roller 33. As the tea leaves continue to move, the tea leaves pass through the conveyance of the impurity removal plate 31 and at the same time pass under multiple static rollers 33, effectively removing the dust and impurities in the tea leaves. Then the clean tea leaves move to the position of the discharging plate 8, and a collection hopper can be arranged below the discharging plate 8 to collect the tea leaves.
[0047] Meanwhile, when the static roller 33 rotates, due to the setting of the spring 75, it drives the scraping plate 64 to closely adhere to the surface of the static roller 33. Thus, when the static roller 33 rotates, the dust and impurities attached to its surface will be scraped off by the scraping plate 64 and move into the guiding groove 63. After the first vibrating motor 62 starts, the guiding groove 63 vibrates, and the dust in it moves along the inclined bottom surface of the guiding groove 63 into the concentrating groove 66, and the dust in multiple guiding grooves 63 is synchronously concentrated into the concentrating groove 66. After the second vibrating motor 65 starts, it drives the concentrating groove 66 to vibrate, so that the dust in the concentrating groove 66 is centrally discharged through the dust discharging hopper 67, facilitating the treatment of the dust.
[0048] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
