Description

Technical Field

[0001] This utility model belongs to the technical field of synchronous screening and reuse device for tunnel face slag, and more specifically, it relates to a synchronous screening and reuse device for tunnel face slag. Background Technology

[0002] The tunnel face excavation and soil synchronous screening and reuse device can receive excavated soil in real time during the tunneling process, perform multi-stage screening and mud-water separation, and quickly separate reusable aggregates and fine materials, realizing the on-site resource utilization of excavated soil, reducing transportation volume and environmental pollution, and improving construction efficiency and green construction level.

[0003] Current tunnel face excavation and soil synchronous screening and reuse devices use conveyor belts to transport the excavated excavated soil to the corresponding processing equipment. However, the excavated soil contains a large number of stones or solidified soil clods. Large stones can easily get stuck in belt conveyors, screw conveyors, or excavated soil pipelines, causing transportation interruptions and increasing maintenance frequency. Excavated soil containing large stones is difficult to use directly for backfilling, brick making, and other reuse processes, requiring additional crushing treatment, which increases the number of processes and energy consumption. At the same time, the stones can easily generate significant noise and dust when they collide with the equipment during transportation and loading / unloading, affecting the construction environment.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a device for synchronous screening and reuse of excavated soil at the tunnel face, in order to achieve a more practical purpose. Utility Model Content

[0007] Furthermore, a device slot is provided on one side of the housing, and one end of each of the two pairs of rotating shafts passes through one end of the processing slot and extends into the device slot.

[0008] Furthermore, each of the two pairs of rotating shafts is fixedly connected to a pair of first gears and a pair of second gears at one end located within the equipment slot, and a synchronous belt drives between each pair of first gears and second gears.

[0009] Furthermore, a pair of motors are installed inside the equipment slot, and the output end of the motors is connected to one end of the shaft connected to the first gear via a coupling.
