[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a green brick tea raw material screening device, including a housing 1, a cleaning mechanism 2 provided on one side of the housing 1, the cleaning mechanism 2 including a fixing frame 201, a first motor 202 fixedly connected to the top of the fixing frame 201, a drive shaft 203 fixedly connected to the output end of the first motor 202, a sieve plate 204 fixedly connected to the bottom of the drive shaft 203, a second motor 205 provided on the front side of the bottom of the housing 1, a rotating shaft 206 fixedly connected to the output end of the second motor 205, a fixing rod 207 fixedly connected to the surface of the rotating shaft 206, and a spring 208 fixedly connected to the central shaft at the bottom of the housing 1. A base plate 209 is fixedly connected to the housing 1, and a hammer 210 is fixedly connected to one side of the base plate 209. A hot air blower 211 is installed on the right side of the housing 1, and an exhaust pipe 212 is connected to one side of the hot air blower 211. A nozzle 213 is connected to one side of the exhaust pipe 212. By setting up a cleaning mechanism 2, while screening materials, the first motor 202, the second motor 205, and the hot air blower 211 are started. The first motor 202 drives the drive shaft 203 to rotate, and the drive shaft 203 drives the screen plate 204 to rotate. The second motor 205 drives the rotating shaft 206 to rotate, and the rotating shaft 206 drives the fixed rod 207 to rotate. During the rotation of the fixed rod 207, it will interact with the base plate 209. The contact point causes the base plate 209 to move. After the fixed rod 207 moves away from the base plate 209, the tension of the spring 208 causes the base plate 209 to move. The base plate 209 then moves the hammer 210 to strike the screen plate 204, causing the blocked material to separate from the screen plate 204. A hot air blower 211 draws in external gas, which is then sprayed onto the surface of the screen plate 204 through the exhaust pipe 212 and nozzle 213 to dry the screen holes and prevent material from easily adhering to the screen holes due to moisture. A fixed base is fixedly connected to one side of the second motor 205, and one side of the fixed base is fixedly connected to the housing 1. By setting the fixed base, the second motor 205 is stabilized. The second motor 205 is limited during operation; a partition 214 is movably connected to the surface of the drive shaft 203, and both the front and back of the partition 214 are fixedly connected to the housing 1. By setting the partition 214, the material is blocked, thereby facilitating cleaning work; a bracket is fixedly connected to one side of the hot air blower 211, and one side of the bracket is fixedly connected to the housing 1. By setting the bracket, the operation of the hot air blower 211 is stabilized and the hot air blower 211 is limited; a round hole is opened at the bottom of the housing 1, and the inner cavity of the round hole is slidably connected to the striking hammer 210. By setting the round hole, the operation of the striking hammer 210 is stabilized and the striking hammer 210 is balanced and supported.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 On the other side of the housing 1, a screening mechanism 3 is provided. The screening mechanism 3 includes a drive gear 301, the inner cavity of which is fixedly connected to the drive shaft 203. A driven gear 302 meshes with one side of the drive gear 301, and a connecting shaft 303 is fixedly connected to the left side of the driven gear 302. A turning roller 308 is movably connected to the top of the left side of the housing 1. A synchronous pulley 304 is fixedly connected to the left side of both the turning roller 308 and the connecting shaft 303. A synchronous belt 305 meshes with the surface of the synchronous pulley 304. An air guide pipe 306 is connected to the other side of the exhaust pipe 212, and a connector 307 is connected to one side of the air guide pipe 306. One side of the shaft is connected to the housing 1. By setting the screening mechanism 3, the material is screened by the sieve plate 204. At the same time, the drive shaft 203 drives the drive gear 301 to rotate. The drive gear 301 drives the driven gear 302 to rotate. The driven gear 302 drives the connecting shaft 303 to rotate. Through the cooperation of the synchronous pulley 304 and the synchronous belt 305, the turning roller 308 is driven to rotate, turning the material over, thus making the screening efficient. The surface of the connecting shaft 303 is movably connected to the fixed block through the bearing. The bottom of the fixed block is fixedly connected to the housing 1. By setting the bearing and the fixed block, the operation of the connecting shaft 303 is stabilized and the connecting shaft 303 is limited.

[0024] Working principle: By setting up the cleaning mechanism 2, while screening materials, the first motor 202, the second motor 205 and the hot air blower 211 are started. The first motor 202 drives the drive shaft 203 to rotate, and the drive shaft 203 drives the screen plate 204 to rotate. The second motor 205 drives the rotating shaft 206 to rotate, and the rotating shaft 206 drives the fixed rod 207 to rotate. During the rotation of the fixed rod 207, it will contact the bottom plate 209 and drive the bottom plate 209 to move. After the fixed rod 207 moves away from the bottom plate 209, the tension of the spring 208 drives the bottom plate 209 to move. The bottom plate 209 drives the hammer 210 to move and knock on the screen plate 204, so that the blocked material is separated from the screen plate 204. The hot air blower 211 draws in the outside gas, and then sprays the heated gas onto the surface of the screen plate 204 through the exhaust pipe 212 and the nozzle 213 to dry the screen holes and prevent the screen holes from being damp and causing the material to easily adhere.
