[0025] See the instructions attached Figure 2 、 3As shown in Figure 4, the lifting drive assembly 6 includes two parallel vertical rods 601. The lower ends of the two vertical rods 601 are fixedly connected to the base 1. The upper ends of the two vertical rods 601 are fixedly connected to each other through a crossbar. A motor 605 is fixedly installed on the crossbar. The motor 605 adopts a dual-axis rotary motor. The two output shaft ends of the motor 605 are respectively connected to the rope winding wheel 602. The outer side of each rope winding wheel 602 is wound with a suspension rope 604. Each vertical rod 601 is provided with a lifting chute 603 extending in the vertical direction. Two support structures 5 are respectively slidably arranged in the two lifting chute 603. The lower ends of the two suspension ropes 604 are respectively connected to the corresponding support structures 5. The upper end of each vertical rod 601 is penetrated by a rope threading hole 607 for passing the suspension rope 604. The crossbar is fixed with a shaft support plate 606 for supporting the rotation of the output shaft of the motor 605. In practical applications, the rope threading hole 607 can change the direction and guide the hanging rope 604 to ensure that the hanging rope 604 is in a vertical state.

[0026] See the instructions attached Figure 1 、 3 As shown in 5, the support structure 5 includes a lifting slide 501 that slides up and down in a lifting slide 603, and an electric telescopic rod 502 is fixedly provided on the lifting slide 501. The push rod head of the electric telescopic rod 502 is fixedly provided with a plug post 503. Two first ears 201 are symmetrically distributed with the rotary screen layer 2 on both sides thereof, and a first socket 202 is provided on the lower side of each first ear 201 to cooperate with the plug post 503.

[0027] Working principle:

[0028] When in use, each rotary screen layer 2 is stacked up and down in grades, and screening is performed from top to bottom. When one of the rotary screen layers 2 needs to be disassembled, replaced or cleaned, the lifting drive assembly 6 can drive the supporting structure 5 to move to the position of the rotary screen layer 2. Specifically, the rotation of the output shaft of the motor 605 can simultaneously drive the two rope pulleys 602 to rotate. The rotation of the rope pulleys 602 can realize the winding and retraction of the suspension rope 604, thereby driving the supporting structure 5 to move up and down in the lifting chute 603. The electric telescopic rod 502 of the supporting structure 5 drives the plug post 503 to move close to the rotary screen layer 2 and is located below the corresponding first plug hole 202. The lifting drive assembly 6 drives the supporting structure 5 to move upward, so that the plug post 503 is inserted into the first plug hole 202, thereby realizing the lifting of the rotary screen layer 2, and the rotary screen layer 2 below the lifted rotary screen layer 2 can be disassembled, which is more labor-saving and avoids the trouble of disassembling the rotary screen layer 2 layer by layer.
