Concrete mixing pump

Abstract

The invention relates to a concrete mixing pump. The concrete mixing pump comprises a rack, a stirrer fixed on the front end of the rack, a pumping mechanism arranged on the lower part of the rack, a powered support which is arranged on the rack and positioned on the lower part of the stirrer, a drive stirrer and a power unit of the pumping mechanism, wherein the power unit is fixed on the powered support, the powered support is movably arranged on the rack; when the concrete mixing pump is in the working state, the powered support moves to one side of the stirrer; and when the concrete mixing pump is in the ready state, the powered support moves to the back of the stirrer. The preparation time for the movement of the concrete mixing pump of the invention is reduced; when the power unit on the powered support is used, the power unit is rotated to one side of the stirrer so as to have good ventilation, be far from the stirrer-the pollutant source and reduce the wear and tear of the machine; and when the concrete mixing pump is in the transport state, the power unit is rotated to the back of the stirrer so that the lateral dimension of complete machine is reduced, the demand on road surface and place is lowered, and the concrete mixing pump can better adapt to transport on narrow roads.

Description

technical field [0001] The invention relates to a mixing concrete pump. Background technique [0002] At present, in the process of housing construction, with the improvement of the anti-seismic requirements of the housing, more and more buildings are cast-in-situ with the number of floors below six. The prior art solution is to use a mixer for batching and a concrete pump to pump the concrete. [0003] In order to facilitate transportation, the mixer and concrete pump are usually assembled on the same equipment, and this type of mixing concrete pump is generally used in small construction sites, which often have narrow transportation roads and are constructed by small construction teams, which requires mixing Concrete pumps must be small in size, which is convenient for small vehicles to transport on narrow roads. Therefore, the power system or hydraulic system driving the mixing concrete pump is installed near the feed inlet of the mixer. During normal operation, since ...

AI Technical Summary

Problems solved by technology

During normal operation, since the cement in the mixer is the main source of dust pollution, it is easy to cause the power system or hydraulic system installed close to the mixer to be polluted by cement and cause various problems, affecting its service life. Secondly, it also affects the mixer. The feeding port is convenient

Referring to the patent application No. 95225163.9, a fully automatic concrete mixer is disclosed. The motor of this patent is directly arranged at the rear and lower part of the feeder. The dust during feeding can easily pollute the motor and shorten its service life.
