Multi-bucket excavator An excavator that uses multiple buckets for continuous excavation, transportation and unloading. It is characterized by continuous operation, high productivity, and low unit energy consumption. It is suitable for excavating soil with low hardness and no large rocks. It is used for large-scale construction, water conservancy and mining projects and pipeline laying projects. The operation line is long, and the operations such as river excavation, road cutting, slope repair, and mine stripping are completed. The basic working principle is: on the circumference of the ring chain or wheel frame, install the bucket at certain intervals, the bucket will follow the movement of the bucket chain or the rotation of the wheel frame when working, and the excavation is carried out from bottom to top on the excavation surface. When the shovel rises to the top, the soil is unloaded onto a continuous belt conveyor due to its own weight and transported out. In order to prevent the trajectory of each bucket from repeating the trajectory of the previous bucket, the machine needs to run or rotate at a constant speed during operation, so that the trajectory of the bucket is the movement of the bucket chain or wheel.

A multi-bucket excavator is a device for excavating primary and secondary clay or excavating aging mud in an aging warehouse. It consists of excavation, walking, lifting, conveying and other mechanisms. During the walking process of the equipment, multiple small-capacity buckets fixed on the chain rotate continuously, dig the clay or soil into the bucket, and then pour it on the belt conveyor to transport it away. After digging a stroke, the bucket rod is lowered a certain distance to ensure that the bucket has a certain digging depth. The inclination angle of the multi-bucket excavator can reach 50 °, the digging depth is 2.5-12m, and the output is 20-80m3/h. According to the excavation direction, it is divided into three types: up, down, and two-way. According to the walking mode, there are two types: crawler type and crawler type., the multi-bucket excavators used in the aging warehouse of the brick factory are generally track type.

The multi-bucket excavator cuts the raw materials into small pieces in the form of planing, and the raw materials of different layers can be well homogenized.

In foreign countries, water jets are installed on multi-bucket excavators for mining raw materials. When the raw materials are excavated into finely broken pieces, the raw materials to be excavated are first wetted to facilitate their looseness.
