Description
Technical Field
The utility model belongs to the technical field of the concrete processing, a concrete mixer for construction is related to.
Background
Concrete is a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. The term concrete generally refers to cement as the gel material and sand and stone as the aggregate; the cement concrete, also called as common concrete, is obtained by mixing with water according to a certain proportion and stirring, and is widely applied to the building construction process. When the concrete is used, cement, sand and stone need to be stirred and mixed, if the concrete is not sufficiently and uniformly stirred, the viscosity and the firmness of the concrete can be influenced, so that the safety of the whole building is influenced, and the life safety of people is threatened.
The manual stirring mode of concrete in rural and township areas is usually to mix cement powder, sand and stone in proportion, and the first stirring need not to add water, waits to dig an area in the middle of cement powder, sand and the even back of stone misce bene, adds water inside, carries out the second time stirring, and the stirring process is slow and very easily consume workman's physical power, and after the concrete barrelling, mention and pour the area, can cause very big harm to workman's shoulder in the past for a long time.
At present, rural residents consider the economy of building, and building areas deviate from county cities to some extent, so that the rural civil building usually adopts a manual mode to stir concrete; when a civil building is used for pouring a multi-layer ceiling, a manual mode is adopted, usually, silt stones are hung on a template which is installed on a high layer on the bottom layer, then, the concrete is formed by stirring, and then, each pouring area is uniformly lifted in a barreling mode; the manual stirring mode needs to consume a large amount of manpower and material resources, is low in efficiency, and the viscosity and the firmness of the concrete stirred by different manual teams are uneven, so that the concrete meeting the standard cannot be stably stirred.
The device is different from the prior art in that the dry-wet separation type concrete mixer is not adopted to mix concrete in the prior art, and the dry-wet separation type concrete mixer is divided into two times of mixing to ensure that the mixing and stirring time of cement powder, sand and stones is shorter, the forming is fast, and the energy consumption is less.
Although patent numbers CN200420039221.1 and CN200810071636.X disclose double horizontal axis double helix concrete mixer and double helix axis double helix band concrete mixing device respectively, all through powerful continuous stirring, accelerate the whole continuous cycle flow of material in the mixer, produce unique shearing effect, make concrete mixing more violent, even, rapid, realize the high-speed stirring to high strength, high-flow concrete. The device does not divide into the concrete mixing and does wet twice respectively stir, directly adopts the direct one shot forming of double helix, and the stirring time is longer, and the power consumption is more, and the device is inflexible, can not adapt to the use of town civil house building, and needs a plurality of power take off, and is more expensive, and the town dweller can't bear.
