[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to retract an electric telescopic rod, causing it to drive a rack to slide downwards along the inside of a guide rail. This allows the gear to rotate the rotating rod and the screen, tilting the screen at an appropriate angle. The reciprocating swaying of the screen causes the tea leaves to roll to one side and, with the help of an elastic rubber sheet, pass through the discharge port and elastic rubber sleeve into the drying chamber. At this time, the controller controls the heating plates to heat the interior of the drying chamber to a suitable temperature for drying the tea leaves. Simultaneously, the left and right movement of the guide rail causes the L-shaped strip and the chamber door to move left and right, causing the tea leaves to sway. This allows tea leaves of different sizes to enter different drying chambers and provides reasonable temperature control for the heating plates inside each chamber, preventing over-drying or leaving some tea leaves damp, thus improving the drying effect.

[0016] 2. This utility model uses a controller to start the motor, causing its output shaft to drive the disc and rod to rotate. The rod slides inside the guide rail and applies a force to the guide rail, causing the guide rail to drive the rotating rod and slider to slide back and forth along the inside of the groove. Simultaneously, the screen moves back and forth inside the screening box to screen the tea leaves. At the same time, the elastic rubber sheet 2 and elastic rubber sheet 3 are stretched or contracted appropriately, so that the tea leaves can be graded from top to bottom from coarse to fine, thus completing the screening of the tea leaves.

[0025] Examples, such as Figure 1-4 As shown, this utility model provides a grading and drying device for tea processing, including: a sieving box 1, and multiple screens 208 equidistantly and movably arranged inside the sieving box 1. Multiple elastic rubber sheets 209 are equidistantly and fixedly connected to one side of the inner wall of the sieving box 1, and the elastic rubber sheets 209 are fixedly connected to the screens 208. Multiple elastic rubber sheets 210 are equidistantly and fixedly connected to the other side of the inner wall of the sieving box 1, and the elastic rubber sheets 210 are fixedly connected to the screens 208. Multiple sliding grooves 102 are equidistantly opened on one side of the sieving box 1, and sliders 203 are slidably connected inside the sliding grooves 102. A guide rail 2 is fixedly connected to one side of each slider 203, and a rotating rod 21 is rotatably connected to the center of each slider 203. 1. Rotating rod 211 is fixedly connected to screen 208. Multiple rotating rods 211 are rotatably connected to guide rail 2. One end of rotating rod 211 is fixedly connected to gear 212. One side of guide rail 2 is slidably connected to rack 201. Multiple gears 212 are meshed with rack 201. One side of guide rail 2 near the bottom is fixedly connected to electric telescopic rod 202. Electric telescopic rod 202 is fixedly connected to rack 201. Multiple drying boxes 3 are equidistantly arranged on one side of screening box 1. Heating plate 302 is fixedly connected to the top of drying box 3. Multiple discharge ports 103 are equidistantly opened on the other side of screening box 1. Multiple elastic rubber sleeves 303 are equidistantly fixedly connected to the other side of screening box 1. Elastic rubber sleeves 303 are fixedly connected to drying box 3.

[0026] Furthermore, such as Figure 1-4 As shown, a U-shaped plate 204 is fixedly connected to one side of the screening box 1, and a motor 205 is fixedly connected to one side of the U-shaped plate 204. A disc 206 is fixedly connected to the output end of the motor 205, and a round rod 213 is fixedly connected to the eccentric part of the disc 206. One end of the round rod 213 is movably connected to the inside of the guide rail 2. The motor 205 is started by controlling the controller, so that its output shaft drives the disc 206 and the round rod 213 to rotate, so that the round rod 213 slides inside the guide rail 2 and applies a force to the guide rail 2, so that the guide rail 2 drives the rotating rod 211 and the slider 203 to slide back and forth along the inside of the slide groove 102.

[0027] Furthermore, such as Figure 1-4 As shown, multiple L-shaped bars 305 are fixedly connected at equal intervals on one side of the guide rail 2. The L-shaped bars 305 are fixedly connected to the drying box 3. By setting the L-shaped bars 305, when the guide rail 2 moves left and right, the L-shaped bars 305 and the drying box 3 can be moved left and right simultaneously.

[0028] Furthermore, such as Figure 1-4As shown, connecting strips 306 are fixedly connected to the four corners of each pair of opposite sides of the multiple drying boxes 3. Two auxiliary wheel sets 304 are symmetrically fixedly connected to the side of the screening box 1 near the bottom. The connecting strips 306 facilitate the connection of multiple drying boxes 3 together, and the auxiliary wheel sets 304 provide a certain support for the drying boxes 3, making it convenient for the drying boxes 3 to move left and right.

[0029] Furthermore, such as Figure 1-4 As shown, elastic rubber sheets 207 are fixedly connected to the opposite sides of the slider 203. One side of each elastic rubber sheet 207 is fixedly connected to the opposite side of the inner wall of the slide groove 102. The elastic rubber sheets 207 provide a certain degree of shielding effect.

[0030] Furthermore, such as Figure 1-4 As shown, the top of the screening box 1 is provided with a feed inlet 101. The feed inlet 101, the screening box 1, the discharge outlet 103, the elastic rubber sleeve 303 and the drying box 3 are connected. With the above arrangement, tea leaves can enter the screening box 1 from the feed inlet 101 and enter the drying box 3 through the discharge outlet 103 and the elastic rubber sleeve 303.

[0031] Furthermore, such as Figure 1-4 As shown, the holes of the multiple sieves 208 are arranged from coarse to fine from top to bottom. This arrangement facilitates the sieving of multiple tea leaves through the multiple sieves 208.

[0032] Furthermore, such as Figure 1-4 As shown, a door 301 is detachably installed on one side of the drying chamber 3. By opening the door 301, it is convenient to collect the dried tea leaves inside the drying chamber 3.

[0033] Working principle: In use, the tea leaves to be graded are poured into the screening box 1 through the feed inlet 101, causing the tea leaves to fall onto the uppermost screen 208. The controller then starts the motor 205, causing its output shaft to drive the disc 206 and the rod 213 to rotate. The rod 213 slides inside the guide rail 2, applying a force to the guide rail 2. This causes the guide rail 2 to drive the rotating rod 211 and the slider 203 to slide back and forth along the slide groove 102, simultaneously moving the screen 208 back and forth inside the screening box 1. The tea leaves are sieved by repeated shaking, which simultaneously stretches or contracts the elastic rubber sheets 209 and 210. This allows the tea leaves to be graded from coarse to fine from top to bottom, thus completing the sieving process. The controller then retracts the electric telescopic rod 202, causing it to slide the rack 201 downwards along the guide rail 2. The meshing of the rack 201 and gear 212 then drives the rotating rod 211 and the screen 208 to rotate, tilting the screen 208 at an appropriate angle. With the reciprocating swaying of the screen 208, the tea leaves on the screen 208 can roll to one side and, with the help of the elastic rubber sheet 210, enter the drying chamber 3 through the discharge port 103 and the elastic rubber sleeve 303. At this time, the controller controls the heating plate 302 to heat the inside of the drying chamber 3 to a suitable temperature to dry the tea leaves. Simultaneously, the left and right movement of the guide rail 2 can drive the L-shaped strip 305 and the chamber door 301 to move left and right, causing the tea leaves to sway. At the same time, the elastic rubber sleeve 303 is stretched or contracted appropriately, so that tea leaves of different sizes can enter different drying chambers 3 respectively, and the heating temperature of the heating plate 302 inside the different drying chambers 3 can be reasonably controlled, thereby avoiding over-drying of the tea leaves or leaving some tea leaves damp, thus improving the drying effect of the tea leaves. The auxiliary wheel group 304 provides a certain support for the drying chamber 3, thereby reducing the force on the L-shaped strip 305. The elastic rubber sheet 207 provides a certain shielding effect.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
