Separation type concrete mixer

Abstract

The invention relates to a separation type concrete mixer which comprises a mixing bucket, a gravel aggregate bin, a water tank and a cement bin, and is characterized in that the bottoms of the gravel aggregate bin, the water tank and the cement bin lead to the mixing bucket; scales are arranged on the outer walls of the gravel aggregate bin, the water tank and the cement bin; a water inlet valve and a water outlet valve are arranged at the lower end of the water tank; a tilting sand sieving net is arranged at the upper part of the gravel aggregate bin; a coarse material outlet is formed in the gravel aggregate bin making contact with the lower part of the sand sieving net; a gravel inlet valve and a fine material outlet are arranged at the bottom of the wall of the gravel aggregate bin; a cement inlet valve and a cement outlet are arranged at the bottom of the cement bin. The separation type concrete mixer adopting the technical scheme can be used for satisfactorily controlling the concrete control quantity and screening gravels.

Description

technical field [0001] The invention relates to a mixer for construction, in particular to a separate concrete mixer. Background technique [0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. The concrete mixer is mainly composed of a mixing drum, a feeding and unloading mechanism, a water supply system, a prime mover, a transmission mechanism, a frame and a supporting device. Usually, there is only one mixing drum on the mixer, and only one independent mixing chamber is installed in the mixing drum. It is difficult to achieve a reasonable ratio of cement, sand aggregate and water at one time when adding materials, and too much water is required. However, for inexperienced operators, the adjustment process will cause waste of cement and increase construction costs, and sand and gravel aggregates need to be screened before adding to the mixing tank, making the operation The process is complicat...
