The bottom-dump bucket is a critical lifting vessel in mine shaft excavation. It features a controllable gate at the bottom, enabling rapid vertical discharge of materials.
Primarily used for lifting waste rock, lowering concrete and supplies, and occasionally for emergency personnel transport, it is renowned for its stable operation, thorough discharge, and high safety standards.
| Product Advantages |
| Efficient and Thorough Discharge: The bottom gate opens directly, allowing materials to be discharged instantly and completely by gravity without residue. It is particularly suitable for wet, sticky waste rock and concrete. |
| Stable and Safe Operation: The vertical discharge mode prevents significant swinging, minimizing impact on the hoisting system. The locking mechanism is reliable, preventing accidental opening. |
| Versatility: Compatible with lifting various materials such as waste rock, construction materials, and concrete. It can also serve as an emergency personnel lifting vessel when necessary. |
| Durability: Constructed with high-strength steel, it resists impact and abrasion, making it suitable for harsh shaft conditions. |
| Structural Principle |
| Main Structure: Bucket body (cylindrical/tapered), bottom door, top lifting beam. |
| Core Mechanism: Linkage-type self-locking opening and closing system. Automatically locks during lifting; when discharging, the door opens as the bucket seats into the discharge curved rail. |
| Guidance Design: External guide rope sleeves ensure vertical operation without rotation. |
| Workflow |
| Loading → Lifting → Positioning and Discharging (Automatic Opening of Bottom Door) → Returning to the Shaft. |
| The entire process is coordinated with a dedicated discharge frame, featuring a high degree of automation and simple operation. |
