Description

A kind of novel double-horizontal axle concrete-mixer
Technical field
The invention belongs to the building trade equipment technical field, be specifically related to a kind of novel double-horizontal axle concrete-mixer.
Background technology
Concrete is one of main construction material, is widely used in industry, agricultural, traffic, national defence, water conservancy, city and has stable political situation during civilian infrastructure builds, and occupies critical role in national economy.But at present most popular in the building is normal concrete take cement as Binder Materials.In normal concrete, sand, stone play skeleton function, rise in concrete and fill and the contraction of opposing concrete in the setting and harden process.The cement mortar that cement and water form is wrapped in the space between aggregate surface and filler aggregate.Concrete is widely used as main construction material, is because it has the advantages that a lot of other materials do not possess.As low in easy-formation, energy consumption, good endurance, low price and the advantage that can be made into various load-carrying members of being combined with steel.
Along with the development of economic construction, and the quickening of urbanization process, urban infrastructure, development of real estate industry have obtained swift and violent development, have promoted the rapid raising of concrete output.Commerical ready-mixed concrete production is to change the mode of production that traditional scene disperses ready-mixed concrete, realizes an important reform of building industrialization.Concrete commercialization production has improved concrete quality and production efficiency greatly because of specialization and the centralization of its height, has reduced environmental pollution, has alleviated labour intensity.
In the development of Concrete Industry, the construction of concrete mixing plant plays vital effect to the development of commerical ready-mixed concrete.The construction of concrete mixing plant provides condition for concrete intensive production.In mixing plant, various raw material can be orderly leaves position separately in, and sand, stone adopt outdoor storage, and the mode that can take to cover under the strong wind weather condition makes environment avoid polluting, and avoids occurring the phenomenon that yellow sand, dust are existed everywhere.Due to the particularity of cement, need to keep away from moisture and mix foreign material in depositing process, so cement adopts canned depositing, can directly buy bulk cement, reduce production costs.In engineering construction, by adopting commerical ready-mixed concrete, can significantly improve the engineering construction progress, reduce the labour intensity of field worker.Because the production of commerical ready-mixed concrete has very strict standard, various material proportions are all very accurate, so by adopting commerical ready-mixed concrete can effectively guarantee the quality of concrete works.
No matter in quantity still in quality commerical ready-mixed concrete has had history for many years in the development of China,, be no matter also technically or from management, commerical ready-mixed concrete all has a great development.But along with the development of commerical ready-mixed concrete, a large amount of concrete mixer truck has increased the urban transportation burden in city operations, and traffic congestion has affected the normal construction of concrete works.Simultaneously, also will inevitably cause the quality accident problem, although concrete performance depends on concrete match ratio, the leakiness of vibrating in work progress or maintenance are bad also can not obtain good performance.The concrete commercialization is the main flow of Concrete Industry, and these problems are only some destabilizing factors in the commercialization process.Therefore, handling the variety of issue in concrete commercialization process well, promote to a great extent the development process of Concrete Industry, is all very important to building industry and traditional manufacture.
Concrete mixer is by uniform stirrings such as cement, sand, rubble and the water of certain match ratio and prepare concrete special-purpose machinery with batching.Along with the increase of mixer demand, the manufacturer of mixer is also more and more, and market competition is more and more fierce.Most of manufacturer is all take middle-size and small-size mixing plant as main, and the agitating device of existing single horizontal axis the reinforcement of concrete mixer adopts spiral stirring vane, or adopts the stirring shovel that is fixed on mixing arm.When adopting spiral stirring vane, in whipping process, stirring vane and mixed material contact area are little, and little along barrel circumferencial direction and the axial active force of shaft, mixing time is long, and stirring efficiency is poor.When the stirring shovel of mixing arm is fixed in employing, the articulation issues that needs on the one hand to consider mixing arm and shaft and stir shovel, complex structure; On the other hand, stir the shovel area large, during material stirring, resistance is large, and equipment energy consumption is high, and clumsy stirring shovel is difficult to open flocculence material group, and mixing effect is undesirable equally.
Summary of the invention
The purpose of this invention is to provide a kind of novel double-horizontal axle concrete-mixer, be applicable to architectural engineering, have that mixing quality is good, energy consumption is low, efficient is high.Adopt end opening door discharging, alleviate workman's labour intensity, improve the quality of concrete works, can satisfy the job requirement of different occasions.
The present invention is achieved through the following technical solutions:
