Bottom Dump Bucket Mining

The bottom-discharge bucket is a key piece of equipment for concrete pouring during vertical shaft construction in mining. It is widely used in various vertical shaft construction scenarios such as coal mines, metal mines, and non-metallic mines. It is particularly suitable for working conditions where concrete conveying pipes cannot be used, such as in freezing method construction, serving as a reliable and efficient concrete transportation container for vertical shaft pouring operations.

Structural Features and Working Principle:

Features a robust bucket body and high-strength bucket beam structure, providing excellent overall load-bearing capacity and adaptability to the complex underground construction environment.  

Equipped with a sector-shaped gate at the bottom, paired with a handle-type opening/closing mechanism and a locking device, ensuring simple operation and reliable sealing.  

The structural design balances stability and discharge efficiency, facilitating safe and precise concrete placement within the confined shaft space.

Working Principle:

Loading Phase: Concrete is loaded into the bucket at the ground surface or mixing station, with the gate locked to prevent leakage during transport.  

Lowering and Positioning:The bucket is lowered to the pouring position via the hoisting system and smoothly positioned using guiding devices.  

Discharge Operation: The operator opens the sector-shaped gate via the handle, allowing concrete to discharge evenly from the bottom by gravity for rapid pouring.  

Return and Reloading: After discharge, the gate is closed, and the bucket is hoisted back to the surface to cycle for the next operation, meeting the demands of continuous construction.
