Description

The proposed mixer consists of four tanks located one below the other and open at the top with cylindrical sides, a conical bottom and gate valves. The two lower tanks are equipped with agitators on horizontal shafts, rotated, like the shaft of the extraction auger, from a common drive.

The drawing shows a vertical section of a concrete mixer.

The concrete mixer consists of four tanks A, A, B and A & open at the top, installed one below the other in a common frame C. All tanks have cylindrical beads, a conical bottom and a shutter valve; The two lower tanks B and B, with higher sides, are equipped with agitators D on the horizontal shafts E, rotated, as well as the shaft F of the discharge screw G from the common drive using appropriate gears and Gall G chains

In order to supply water to the tank 5, a tank L is installed. The materials required for feeding into the concrete mixer enter the special tanks M, Nvi.O on platform P, laid over the earth excavation R, which is a material receiver. On top of the above tanks, the flooring Z is laid with the corresponding guide nozzles U and with the rails laid on it for the trolleys S with materials. In order to submit the latest

From the receiver I to the upper tank A is intended elevator T.

The operation of the concrete mixer is as follows. In trolleys 5, the right material (gravel, sand, etc.) is delivered to receiver R, discharged through hatch C to the corresponding tanks M, N or O. Then elevator T lifts certain portions of these materials to tank 4, after which the elevator is turned off by means of an idle pulley for some time out of operation, the valve of tank A opens and the material is transferred to tank A with the valve open for transferring material to tank B with an agitator. For proper mixing of the dry material, ten revolutions of the stirrer are sufficient, as directed by the author. Then the valve of tank B is opened and the material is transferred to tank 5, where water from tank L is simultaneously supplied in the required quantity. Then tank B is opened and the concrete mass is transferred to screw O, which thoroughly mixes the concrete and directs it to the work site.

To avoid separate feeding of each material into the tank} you can install in the receiver / an additional mixer for mixing certain portions of materials, after which it is supplied to the tank A using a ready-mixed mixture through the elevator T.

The subject matter of the invention.

A concrete mixer consisting of four tanks placed one above the other in a common frame, open at the top, characterized in that the tanks A, B, and S have cylindrical beads, a conical bottom and are provided with a barrier

valve, with the two lower tanks B, B, have no higher side than the upper tanks, equipped with agitators on the horizontal shafts, rotated, like the shaft of the outgoing auger, from the common drive using appropriate gears and chains Gall.
