发明名称 Concrete distribution device
摘要 A portable manually-operated cement distribution apparatus includes a first tube mounted on a rotatable first cantilever frame, a second tube rotatably attached to the first tube, mounted on a telescopic rotatable second cantilever frame, and at least one additional tube extending from the discharge of the second tube. Removable cantilever struts rotatably mount the first support frame to a plurality of selected support objects, for example a post or building. A third removable cantilever strut is attached to the support object above the first frame. A first plurality of adjustably guide stays, connected to the third cantilever strut, supports the weight of the first tube. A second plurality of adjustable guide stays, attached to the second frame, supports the weight of the second tube and additional tubes. Wheels on the cantilever frames, on adjustable counterweight on the second cantilever frame, and the telescopic feature of the second cantilever frame also help balance the weight.
