CONCRETE MIXER Russian patent published in 1995 - IPC

FIELD: building engineering. SUBSTANCE: concrete mixer has a cantilever fastened on the wheeled frame. The cantilever has the form of two cross beams whose ends are connected by coaxial supports for the dismountable fixture of a mixing assembly in them. The assembly has a drum and a drive fastened on the crosspiece having a handle and supports coaxial to those of the cantilever with the possibility of rotating the mixing assembly in the vertical plane perpendicular to the wheeled axle. The detachable tray has two pairs of C-shaped hooks disposed in two rows from below on the bottom and turned with their hooks towards the mixing assembly rotation with the possibility of engaging, in the position of the concrete mixer, the wheeled axle by the rear pair, when the front part of the tray rests on the soil and of engaging the cantilever crosspieces by both pairs when the mixing assembly is removed. The crosspieces are made as U-shaped arcs turned with their concave surfaces upwards and forming on the wheeled frame a cradle for transporting large-sized loads, sacks for example, when the for transporting large-sized loads, sacks for example, when the tray and the mixing assembly are removed. Being in the position of a concrete mixer, the rear pair of the tray hooks is secured on the wheeled axle and the front part of the tray rests on the soil at the same time. At the moment of loading the mix components, when the drum rotates, the whole mixing assembly is in the state of mixing under the gravitational force. The shock absorbers lean against the cantilever arc. After the mixing is finished the mixing assembly is turned by the handle forward in order to unload the mix into the tray for its further transshipment into a smaller container to deliver to the destination or to use directly from the tray. In this case in order to integrate the cycles of usage and preparation of the mix the next portion can be prepared in the mixing assembly. EFFECT: enhanced efficiency. 1 cl, 6 dwg
