[0026] As a technical optimization solution of the present invention, by setting a positioning mechanism 6, the mounting groove 61 can limit the telescopic rod 5, thereby improving the stability of the telescopic rod 5. The single-head screw 62 and the button cap 63 can be used to movably limit the connecting frame 4, thereby preventing the connecting frame 4 from being away from the top of the telescopic rod 5 and facilitating the up and down movement of the connecting frame 4.

[0028] As a technical optimization solution of the present invention, by setting a vibration component 7, when the top rod 72 moves upward and collides with the connecting frame 4, it can drive the filter screen 2 to vibrate, thereby improving the screening effect of the filter screen 2. At this time, the groove 71 can be used to improve the accuracy of the top rod 72 when it hits the connecting frame 4.

[0029] refer to Figure 3The bottom of the top rod 72 is fixedly connected to a connecting part 8, and the inner wall of the connecting part 8 is movably connected to a movable part 9 through an axle pin. The left and right sides of the screening device body 1 are movably connected to a rotating rod 10 through a bearing. The surface of the rotating rod 10 is fixedly connected to a linking part 11, and the top of the surface of the linking part 11 is movably connected to the inner wall of the movable part 9.

[0030] As a technical optimization solution of the present invention, by setting a connecting member 8, a movable member 9, a rotating rod 10 and a linking member 11, the connecting member 8 is used to connect the top rod 72 and the movable member 9, and the rotating rod 10 is not in the center position inside the movable member 9. When the rotating rod 10 rotates, it can drive the linking member 11 to rotate. The rotation of the linking member 11 can drive the movable member 9 to move up and down. The up and down movement of the movable member 9 can drive the top rod 72 to move up and down.

[0031] refer to Figure 2 A first pulley 12 is fixedly connected to the surface of the rotating rod 10 away from the end of the screening device main body 1, and a transmission rod 13 is provided on the left and right sides of the rear side of the screening device main body 1. The surface of the transmission rod 13 away from the end of the screening device main body 1 is fixedly connected to the second pulley 14, and the first pulley 12 and the second pulley 14 are connected by belt transmission.

[0032] As a technical optimization solution of the present invention, by setting a first pulley 12, a transmission rod 13 and a second pulley 14, the second pulley 14 can be driven to rotate by rotating the transmission rod 13, and the rotation of the second pulley 14 can drive the first pulley 12 to rotate through the belt, and the rotation of the first pulley 12 can drive the rotating rod 10 and the connecting member 11 to rotate.

[0033] refer to Figure 2 The rear side of the screening device body 1 is fixedly connected with a mounting plate 15, the top of the mounting plate 15 is fixedly connected with a double-headed motor 16, and the output end of the double-headed motor 16 is fixedly connected to the end of the transmission rod 13 away from the second pulley 14.

[0034] As a technical optimization solution of the present invention, by setting a mounting plate 15 and a double-headed motor 16, the mounting plate 15 can support and fix the double-headed motor 16. By starting the double-headed motor 16, the output end of the double-headed motor 16 can drive the transmission rod 13 to rotate, and the rotation of the transmission rod 13 can drive the second pulley 14 to rotate.

[0035] refer to Figure 2 A protective shell 17 is provided on the outside of the double-headed motor 16, and the bottom of the protective shell 17 is fixedly connected to the top of the mounting plate 15. The tops of the left and right sides of the screening device body 1 are fixedly connected with fixed plates 18, and the inner wall of the fixed plate 18 is movably connected to the surface of the top rod 72.

[0036] As a technical optimization solution of the present invention, by providing a protective shell 17 and a fixed plate 18, the protective shell 17 can protect the double-headed motor 16, and at the same time can support and limit the transmission rod 13, and the fixed plate 18 can limit the push rod 72, thereby improving the stability of the transmission rod 13 and the push rod 72.

[0037] The working principle and usage process of the present invention: During use, when the filter screen 2 needs to be disassembled and cleaned, the button cap 63 is first rotated to disengage it from the single-head screw 62, and then the filter screen 2 can be driven to move upward and out of the interior of the screening device main body 1 by moving the connecting frame 4 upward, so that it can be cleaned and disassembled conveniently. By starting the double-headed motor 16, the output end of the double-headed motor 16 can drive the transmission rod 13 to rotate, and the rotation of the transmission rod 13 can drive the second pulley 14 to rotate. The rotation of the second pulley 14 can drive the first pulley 12 to rotate through the belt, and the rotation of the first pulley 12 can drive the rotating rod 10 and the connecting member 11 to rotate. Since the rotating rod 10 is not at the center position inside the movable part 9, the rotation of the connecting member 11 can drive the movable part 9 to move up and down, and the movable part 9 can drive the top rod 72 to move up and down. The up and down movement of the top rod 72 can repeatedly impact the connecting frame 4. At this time, the vibration generated by the connecting frame 4 is transmitted to the surface of the filter screen 2, which can improve the screening effect of the filter screen 2. At the same time, the telescopic rod 5 can be used to prevent the connecting member 8 from offsetting when it moves up and down.

[0038] To sum up: this screening device for tea processing, by providing a connecting frame 4 and a telescopic rod 5, can drive the filter screen 2 to move upward and out of the interior of the screening device main body 1 by moving the connecting frame 4 upward, and the telescopic rod 5 can support the connecting frame 4 and the filter screen 2, thereby solving the problem that after the filter screen has screened the tea leaves, a large amount of dirt, tea residue and other impurities will remain on its surface, so the user needs to clean it to avoid blockage, and the filter screen is installed inside the feed trough, which is not convenient for the user to disassemble and is therefore inconvenient to clean.
