Automated Truck Unloader Bulk Material Handling Process

The automated truck unloader serves as the critical hub in modern bulk material handling systems. Through its intelligent four-phase workflow—precise positioning, sealed unloading, dynamic conveying, and smart stacking—it achieves high-efficiency operations. Zoomry’s ZRLS/ZRLD series adopts modular designs, meeting core demands across mining, port, and other scenarios for 1,800 tph throughput, ±5 cm positioning accuracy, and enclosed dust suppression.

I. In-Depth Analysis of Core Technical Workflow

Phase 1: Precision Vehicle Positioning

Zoomry’s truck unloader integrates LiDAR and machine vision to generate real-time 3D point cloud models as trucks enter the work zone. Guided by a 12.1% gentle slope (6.7° incline) and directional indicators, vehicles position themselves at the V-shaped hopper centerline with ±5 cm accuracy. Dual/four-lane parallel designs significantly enhance throughput efficiency.

Phase 2: Sealed Unloading & Dust Control

When truck beds elevate, 4.8-meter-deep V-hoppers deploy anti-splash grilles as physical barriers. Polyurethane sealing skirts and bottom damping plates collaboratively capture suspended particles ≤2μm, suppressing dust diffusion. The unloading zone features negative-pressure extraction, ensuring ISO 14001 compliance.

Phase 3: Adaptive Conveying Control

Key belt conveyors integrate load cells and radar material scanners. If instantaneous flow exceeds 115% capacity, PLC controllers reduce belt speed from 3.5 m/s to 3.1 m/s within 0.8 seconds. Under light loads, speeds increase to 4.0 m/s to save energy. Overloads trigger 10% speed reduction and audible-visual alarms, while empty segments optimize energy use with 15% acceleration.

Phase 4: Intelligent Stockpiling Coordination

Via industrial 5G modules, the truck unloader exchanges material-level data with Zoomry’s ZR-SF series telescopic stacker. Systems autonomously plan stacking paths using 3D yard models to prevent segregation and maximize space utilization.
