How to control the up-and-down movement of suction nozzle cylinder?

Cylinder control. The suction nozzle cylinder unit includes a cylinder and a suction nozzle. The working principle is that the suction nozzle moves up and down through the cylinder. When the suction nozzle is not working, it touches the ground through the roller. The work of the multi-degree-of-freedom connector is to make the suction nozzle float up and down with the ups and downs of the road surface to ensure that the suction nozzle has a certain distance from the ground.
