Activating the hydraulic cylinder 4 pulls the rack 5 in the opposite direction, allowing the protective cylinder 9 to be removed. When cleaning the protective cylinder 9 is required, the water pump 11 is first activated. The water pump 11 directly draws water from the outside, which is then discharged through the telescopic pipe 12. 12 is conveyed to the hollow ring 19 and then discharged by the nozzle 20. The nozzle 20 is arranged at an angle and washes the protective cylinder 9, which can wash away the debris blocking the protective cylinder 9.
