CONCRETE BLOCK EDGES AND SURFACE TREATMENT MACHINE

摘要

The present concrete block edges and surface treatment machine is specifically suitable for hollow blocks such as blocks for retaining walls. The machine comprises a frame, a concrete dual-block magazine assembly, for receiving for treatment concrete blocks, and an impacting assembly, both mounted to the frame. The concrete block magazine assembly defines an axis and has two opposite side block-receiving openings along the axis from which the exposed side of concrete blocks is to extend during the treatment. The impacting assembly includes loosely mounted reciprocating impacting elements. The concrete block magazine assembly and the impacting assembly are so mounted to the frame relatively to each other as to allow a movement of the impacting elements relatively to the concrete block magazine along a path which causes the impacting elements to impact on the exposed side of the concrete block when the impacting elements and the exposed side intersect course during the movement. The path is such that the impacting elements vary their impact on different portion of the exposed side. According to a specific embodiment, the dual-block magazine is rotatably mounted to the frame and the path is an arc of circle.
