[0029] In the embodiment, considering that the load of the tea box is different, the existing wind screen device does not have the function of adjusting the position of the fan 3, and the fan 3 is too far away from the conveying belt, so that the tea box with missing loading and insufficient capacity cannot be blown off, thereby affecting the screening effect, therefore, by setting the adjusting mechanism, when the wind force generated by the fan 3 cannot blow off the tea box with missing loading and insufficient capacity on the conveying belt 1, the traction block 12 is pushed upward, the traction rod 11, the movable block 8 and the positioning rod 9 are driven to move upward, the positioning rod 9 is separated from the inside of the positioning hole 10, then the position of the fan 3 and the moving block 4 is moved along the track of the T-shaped sliding block 5 and the T-shaped sliding groove 6, so that the fan 3 is close to the conveying belt 1, after reaching the appropriate position, the traction block 12 is loosened, the elastic force generated by the spring 24 pushes the movable block 8 and the positioning rod 9 to move downward, so that the positioning rod 9 enters the corresponding positioning hole 10, the fixing of the shell 7, the movable block 8 and the fan 3 is completed, and the fan 3 after adjusting the position can effectively blow off the tea box with missing loading and insufficient capacity, thereby improving the screening effect.

[0030] The top of the movable block 8 is fixedly connected with a spring 24, and the top of the spring 24 is fixedly connected with the inner wall of the shell 7.

[0031] In the embodiment, by setting the spring 24, the traction block 12 can be loosened, the elastic force generated by the spring 24 pushes the movable block 8 and the positioning rod 9 to move downward, so that the positioning rod 9 enters the corresponding positioning hole 10, and the reset function is achieved.

Therefore, the lifting mechanism is arranged, so that when the blowing height of the fan 3 does not match the height of the tea box, the handle 16 is rotated to drive the threaded rod 17 to rotate around the bearing 19. At the same time, the external threads on the surface of the threaded rod 17 press the internal threads in the threaded hole 18, so that the telescopic block 15 moves upward. The telescopic block 15 drives the mounting plate 2, the movable block 8, the fan 3 and other structures to move upward along the trajectory of the guide block 22 and the guide groove 23 until the height matches the height of the tea box.

[0035] In this embodiment, considering that the height of the tea box is different, if the blowing height of the fan 3 does not match the height of the tea box, the tea box with missing loading or insufficient capacity cannot be blown off, thereby affecting the screening effect. Therefore, the lifting mechanism is arranged, so that when the blowing height of the fan 3 does not match the height of the tea box, the handle 16 is rotated to drive the threaded rod 17 to rotate around the bearing 19. At the same time, the external threads on the surface of the threaded rod 17 press the internal threads in the threaded hole 18, so that the telescopic block 15 moves upward. The telescopic block 15 drives the mounting plate 2, the movable block 8, the fan 3 and other structures to move upward along the trajectory of the guide block 22 and the guide groove 23 until the height matches the height of the tea box.
