Stacker reclaimer, also known as bucket wheel stacker and reclaimer, stacker and reclaimer, is a high-efficiency continuous loading and unloading machine. Bucket wheel stacker and reclaimer is a high-efficiency loading and unloading machine used for continuous conveying of both stacking and reclaiming materials in large dry bulk storage yards.
The stacker-reclaimer has two operation modes: stacking and reclaiming. The bulk material transported by the belt conveyor is unloaded to the belt conveyor on the boom by the tail truck, and is dumped from the front end of the boom to the material yard. Through the operation of the whole machine, the rotation and pitch of the boom can make the material pile form a neat shape of trapezoidal section. Reclaiming is realized continuously through the rotation of the boom and the rotation of the bucket wheel. The material is unloaded to the reverse-running boom belt conveyor through the unloading plate, and then unloaded to the material yard belt conveyor through the hopper below the center of the machine to be transported away. Through the operation of the whole machine, the rotation and pitch of the boom can make the bucket wheel take out the material in the storage pile.
The stacker is mainly composed of cantilever part, traveling mechanism, hydraulic system, incoming car, track part, cable pit, power cable reel, control cable reel, limit switch device, etc. The stacker-reclaimer needs to establish an overhaul, intermediate overhaul and routine maintenance system during the application period. During the overhaul, all parts of the stacker should be removed for inspection and replaced with worn parts and seals. The main contents of the overhaul are:
Gear pumps, solenoid valves and various valve parts in the hydraulic system; wear parts of hydraulic cylinders; various protection devices and level switches; wear of reducers, brakes and wheels in the traveling mechanism; whether the bearings of each rotating part are in good condition, And according to the service life and usage of the wear parts to decide whether to repair or replace.
