I. Product Overview
The hand-held chain trencher is a small engineering machinery, mainly used for trenching operations in agricultural irrigation, cable laying, pipeline burial and other occasions. Compared with the traditional manual trenching method, this equipment has significant advantages such as high operating efficiency, low labor intensity and good trenching quality.
II. Main structural components
Power system
Adopts single-cylinder/double-cylinder air-cooled diesel engine or gasoline engine;
Power range 8-15 horsepower;
Equipped with centrifugal clutch to achieve smooth start;
Transmission system
Gear transmission realizes multi-speed shifting;
Chain transmission mechanism transmits power;
Some models use hydraulic transmission system;
Trenching device
Manganese steel chain;
Replaceable alloy blade;
Depth adjustment mechanism (mechanical or hydraulic);
Travel system
Rubber track or steel wheel design;
Steering control handle;
Braking device;
III. Working principle
The engine power drives the trenching chain to rotate at high speed through the transmission system, and the blade on the chain cuts the soil to form a groove. The cut soil is discharged out of the ditch through the screw conveyor or the soil throwing device. The operator adjusts the ditching depth and walking direction through the control handle.
