High Quality Chain Trencher

High Quality Chain Trencher

With the development of the economy, the country has increased its efforts in infrastructure construction, the number of underground pipelines and electric (optical) cable laying projects has increased sharply, and the quality requirements have increased.

A trencher is a new type of trenching and grooving equipment, specifically a mechanical equipment used for laying farmland pipelines, urban and rural optical cables, etc.

The rotation of the diesel engine in the power system is transmitted to the reduction box in the reduction system through a quadruple belt, which drives the main sprocket installed on it, and the main sprocket drives the chain engaged with it to rotate.

The tool is installed on the chain. Under the drive of the power system, the chain drives the tool to rotate and translate, thereby realizing trenching.

The chain trencher described in this scheme can achieve the same depth, uniform width and adjustable size of the trench, which greatly improves the excavation quality and efficiency.

The chain trencher uses a power of 60-140 horsepower. In order to dig trenches of different widths, it can be converted into single and double chains. It can dig trenches with a width of 13-55 cm and a depth of up to 1.5 meters. The most important feature of this utility model is the fast digging speed, which can reach 500-700 meters/hour, low failure rate, and simple and practical.

The rotary trencher requires very little traction power, and the thrown soil can be evenly spread on both sides of the trench without trimming.

However, the machine structure is more complicated, the productivity is lower than that of the plowshare trencher, and the energy consumption per unit of soil is higher.It takes about 0.15-0.45 kilowatts/hour to mill and throw 1 cubic meter of soil. The tractor matched with the rotary trencher needs to have an ultra-low gear.
