Embodiment Construction

[0023] like figure 1 Shown, a kind of foundation raw material mixing device for highway engineering, it comprises vertical circular mixing barrel 5 and the double ribbon agitator 13 that is arranged in mixing barrel 5, and described mixing barrel 5 bottom is conical, and top is provided with There are three feed ports, each feed port is provided with a set of quantitative feeding unit, and the bottom of the mixing barrel 5 is provided with a discharge port. The lower conical mixing barrel 5 can discharge the mixed raw materials inside it more cleanly. The quantitative feeding unit transports the three raw materials of cement, sand and gravel into the mixing tank 5 in proportion, and is evenly stirred by the double ribbon agitator 13, and is discharged from the discharge port at the bottom of the mixing tank 5, ensuring that the three raw materials The ratio of the ratio avoids the problem of randomness and inaccurate ratio when mixing foundation materials for highway engineer...

Abstract

The invention discloses a mixing device for foundation raw materials for highway engineering. The mixing device comprises a vertical mixing barrel and a double-helical-ribbon agitator arranged in themixing barrel. The lower part of the mixing barrel is conical, the upper part of the mixing barrel is provided with at least two feeding ports, each feeding port is provided with a quantitative feeding unit, and the bottom of the mixing barrel is provided with a discharging port. The three raw materials of cement, sand and stones are separately conveyed into the mixing barrel in proportion by thequantitative feeding unit, stirred to be uniform by the double-helical-ribbon agitator and discharged from the discharging port in the bottom of the mixing barrel, the proportion of the three raw materials is guaranteed, and the problems that when the foundation raw materials for highway engineering are mixed, the randomness is high and the proportion is inaccurate are avoided. The double-helical-ribbon agitator has the advantages of high mixing efficiency, uniform mixing and energy saving and can effectively reduce accumulated materials on the wall of the mixing barrel.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to a foundation material mixing device for highway engineering. Background technique [0002] Concrete is a commonly used material for road foundations, and a concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. Usually, it is necessary to manually add various raw materials into the hopper in proportion, then lift the hopper, put the raw materials into the mixer, and then add water while stirring. The mixing ratio of raw materials and the ratio of adding water are inaccurate and difficult to control, and are completely controlled by the operator, which is relatively random. At the same time, since the concrete mixer and the mixing site are open, there is a lot of dust on the site, and the concrete cannot be continuously supplied. Contents of the invention [0003] The technical problem to be solve...
