AI Technical Summary
Existing technologies cannot efficiently and quickly collect and clean the sediment at the bottom of the pile foundation construction hole, which is inconvenient.
The forward rotation of the connecting seat causes the swing plate to retract to the side of the limiting seat. The movable rod and fixed rod on the rotating seat contact and scrape against the inner wall of the hole, causing the adhering waste residue to fall off. Then the limiting seat reverses, the swing plate opens to collect the waste residue, and it is conveyed to the discharge pipe by the conveying auger.
It enables rapid and centralized cleaning of sediment at the bottom of the hole, improves cleaning efficiency, adapts to the cleaning needs of holes of different diameters, and avoids the influence of the conveyor cylinder rotating with the rotating seat.
