Abstract
A concrete funnel and placement system comprising a funnel-type apparatus removably securable to a concrete chute having a retainer element coupled to a funnel element. The funnel element includes a downwardly sloping base forming an aperture for concrete to flow through. The aperture may be any shape or size, and one or more interchangeable discharge plates may be included in order to selectively change the shape and/or size of the aperture. Further, the aperture of the funnel element may be selectively opened or closed. Bearings, sprockets, rollers or other rotatable mechanisms may be included to allow the funnel element to rotate 360° with respect to the retainer element. The retainer element may include a gasket forming a seal with the funnel element to prevent concrete from impeding rotation. The retainer element may be hingedly secured to the concrete chute allowing the retainer element to be adjusted such that it is substantially horizontal while pouring concrete, independent of the angle of the concrete chute. The funnel-type apparatus may be in communication with the concrete truck, thus allowing the rotation and adjustment of the funnel-type apparatus to be controlled by …
