Single unit walking type material distribution device and method thereof

Abstract

This invention provides a single-unit, mobile concrete placement device and its placement method. The device uses multi-modal sensors at the front end to fuse environmental and trench data, and a control center's path tracking algorithm drives the chassis to automatically traverse the trench and avoid obstacles. During operation, visual monitoring of the material inlet status enables automatic stopping when material is insufficient; simultaneously, a digital elevation model of the trench bottom is generated to analyze the center coordinates and volume compensation deviation of uneven target areas. Based on the analyzed data, the control center dynamically adjusts the spatial yaw and pitch angles of the placement pipe through inverse kinematics calculations to align with potholes, and dynamically adjusts the opening size of the hopper's opening and closing plate in conjunction with vehicle speed for precise quantitative filling, while simultaneously adjusting the vibration frequency to prevent arching. Sensors at the rear of the device continuously evaluate the root mean square error of the paved road surface's smoothness, triggering closed-loop feedback compensation when the error exceeds the standard. Furthermore, the device supports edge-end data feedback and cloud-based model iterative training, continuously optimizing the placement strategy. This invention achieves unmanned and precise trench backfilling operations, saving materials and eliminating the need for manual secondary leveling.
