DETAILED DESCRIPTION

[0023] like Figures 1 to 4 As shown, the utility model provides a screening device for tea processing, comprising a workbench 1; a vertical fixed column 2 is arranged on the workbench 1; a plurality of horizontally arranged fixed boxes 4 are connected to the peripheral side of the fixed column 2 through a clamping block 3; a plurality of sieve holes are opened on the bottom wall of the fixed box 4; a vibrating member 5 is installed on the outer side wall of each fixed box 4; a cover 6 is covered on each fixed box 4; a plurality of parallel rotating rods 7 are rotatably connected between the opposite side walls of the cover 6; a plurality of stirring bars 8 are arranged on each rotating rod 7, and the stirring bars 8 can turn over the tea leaves in the fixed box 4.

[0024] The principle and beneficial effects of the above technical solution:

[0025] Pour the tea leaves into the fixed box 4, and then cover the corresponding fixed box 4 with the cover 6. With the vibration of the vibrating member 5, the tea leaves meeting the screening conditions can be retained in the fixed box 4, while the impurities can fall through the sieve holes. While the vibrating member 5 is working, the rotating rods 7 are controlled to rotate, thereby driving the stirring bars 8 to push the tea leaves in the fixed box 4, so that the tea leaves are in an active state, avoiding aggregation and blocking the sieve holes, so that the impurities can be quickly discharged through the sieve holes.

[0026] In the present application, by controlling the rotation of a plurality of rotating rods 7, the stirring bars 8 are driven to push the tea leaves in the fixed box 4, so that the tea leaves remain in an active state, thereby preventing the tea leaves from gathering together and clogging the sieve holes during the screening process, which helps to improve the screening efficiency; at the same time, the rotation of the stirring bars 8 can accelerate the separation of impurities in the process of pushing the tea leaves, so that the impurities can be discharged through the sieve holes, thereby improving the impurity removal efficiency.

[0027] In this embodiment, Figure 2 , 3As shown, each cover 6 has a plurality of through slots on the side wall facing away from the fixed box 4; each through slot is located directly above the corresponding rotating rod 7 and is parallel to the rotating rod 7; each cover 6 is provided with a fixed frame 9 opposite to the through slot; a screw 10 parallel to the rotating rod 7 is provided between the opposite side walls in each fixed frame 9; a slider is threadedly connected to each screw 10, and the slider is slidably arranged in the corresponding fixed frame 9; a fan 11 is installed on the side wall of each slider facing the fixed box 4; a movable motor is installed on the outer side wall of each fixed frame 9; the power end of each movable motor rotates and extends into the fixed frame 9 and is connected to one end of the screw 10; the other end of the screw 10 is rotatably connected to the corresponding side wall of the fixed frame 9.

[0028] The principle and beneficial effects of the above technical solution:

[0029] The screw 10 is driven to rotate by the mobile motor, which can drive the slider to slide in the fixed frame 9, and cooperate with the fan 11 to send air into the fixed box 4, so that the dust generated in the process of pushing the tea leaves can be blown out through the sieve holes.

[0030] The combination of the air supply of the fan 11 and the slider of the screw 10 can effectively blow out the dust generated in the process of pushing the tea leaves through the sieve holes, keep the fixed box 4 relatively clean, and improve the hygiene and quality of the tea leaves; at the same time, in conjunction with the rotation of the stirring bar 8, the airflow generated by the fan 11 can blow away the tea leaves that may be adhered to the stirring bar 8, thereby avoiding waste of tea leaves.

[0031] In this embodiment, Figure 1 , 4 As shown, a receiving groove is opened on the top of the fixed column 2; an electric telescopic rod 12 is installed in the receiving groove; the telescopic end of each electric telescopic rod 12 is connected to an intermediate column 13 covering the receiving groove; each cover 6 is connected to the intermediate column 13 through an intermediate strip 14.

[0032] The principle and beneficial effects of the above technical solution:

[0033] The electric telescopic rod 12 can drive the middle column 13 to move up and down, so that the cover 6 can be driven to move through the middle bar 14, so that after the tea leaves are screened, there is enough space to take out the tea leaves in the fixed box 4.

[0034] In this embodiment, Figure 1 , 2 As shown, a plurality of flip motors 15 are installed on the outer side wall of each cover 6; the power end of each flip motor 15 rotates and extends into the cover 6 and is connected to one end of the rotating rod 7; the other end of each rotating rod 7 is rotatably connected to the corresponding side wall of the cover 6.

[0035] The principle and beneficial effects of the above technical solution:

[0036] The corresponding rotating rod 7 is driven to rotate by the flipping motor 15, so that the stirring bar 8 can push the tea leaves in the fixed box 4, thereby ensuring that the tea leaves are in an active state.

[0037] In this embodiment, Figure 2 As shown, each vibration member 5 includes a vibration motor installed on the outer wall of the fixed box 4; the power end of each vibration motor is connected to a vibration block 16; when the vibration motor rotates, the vibration block 16 can collide with the outer wall of the fixed box 4.

[0038] The principle and beneficial effects of the above technical solution:

[0039] The vibration motor is controlled to rotate, thereby driving the vibration block 16 to intermittently collide with the fixed box 4, thereby generating vibration, accelerating the separation of tea leaves and impurities, and the separated impurities can be discharged through the sieve holes.

[0040] In this embodiment, Figure 1 As shown, a plurality of collecting boxes 17 are placed on the workbench 1 ; each collecting box 17 is located directly below the corresponding fixing box 4 .

[0041] The principle and beneficial effects of the above technical solution:

[0042] The collecting box 17 can effectively collect and store the impurities separated during the screening process, preventing the impurities from falling onto the workbench 1 or the ground, thus helping to keep the working environment clean and tidy.
