The working principle of the utility model ditching machine:

The hydraulic oil tank installed on the hydraulic remote control tractor provides pressure to the hydraulic motor through the hydraulic distributor to drive the hydraulic motor. The power output shaft of the hydraulic motor drives the driving sprocket to rotate, thereby driving the chain to complete the operation. The working intensity of the trencher is determined by the hydraulic pressure provided to the hydraulic motor. The hydraulic pressure is strong, and the hydraulic pressure is weak.

The hydraulic oil tank installed on the hydraulic remote control tractor provides hydraulic pressure to oil cylinder I and oil cylinder II respectively through the hydraulic distributor, and controls its lifting to change the depth of operation.

The ditching machine of the utility model can throw the excavated silt to both sides of the ditch while ditching.
