Ditching machine is an efficient and practical means new chain opener. The main from the power system, deceleration system, the chain of transmission and sub-soil system. Diesel belt after passing through the rotation to the clutch, drive walk gearbox, drive shaft, rear axle to achieve linear motion chain-type trenching machine forward or backward. After passing through the rotation quadruple with diesel power systems to the reduction gear box drive system is mounted on the main sprocket, the main drive sprocket engages the chain rotation. The tool is mounted on the chain, the drive power system, the chain driven rotation plus translation tool, enabling ditching. The program uses the chain-trencher can dig trenches to achieve the same depth, width uniform and adjustable size, greatly improving the quality and efficiency of mining. Chain Trencher with a power ranging from 60-140 horsepower, the width of the trench excavation different type, can be converted into two single or double chain, can excavate 13-55 cm in width, depth of up to 1.5 meters groove type, the utility model is the most important feature of the excavation speed of up to 500-700 m / hr, the failure rate is low, simple and practical. Introduction It is designed for 15-95 horsepower ultra-low speed (100-300 meters per hour, ordinary tractor can meet the requirements by installing ultra low speed control) tractor design of new products. The machine uses a chain belt scraper opener, trenching width of 16-40 cm, depth adjustable ditching, ditching maximum depth of 180 cm. Suitable for farmland irrigation ditch work to underground pipes, water pipes and underground cabling and other work.
