Instruction

Concrete mixer is a mix of cement, sand and gravel aggregate and water and mix made of concrete machinery.Mainly by mixing barrel, loading and unloading mechanism, water supply system, engine, transmission mechanism, frame and the supporting device, etc.Concrete mixer, including through the shaft and drive motor.Concrete mixer atlas (3 copies)
Structure connection of driving and driven by the drive mechanism roller, the roller cylinder jacket around the cylinder cylinder gear ring set, set with the ring gear meshing gear on the shaft.The utility model has simple structure, reasonable, the use of mesh gear, gear ring, which can effectively overcome the fog had, between the roller and the mixer drum skid phenomenon;The transmission mechanism and can further ensure that eliminate skid phenomenon between the roller and mixer drum

Classify

According to the nature of work points batch (batch) and continuous;According to the mixing principle points fall since the pattern and force pattern;According to the installation points and stationary and mobile;According to the way of discharging points tilting type and the tilting type;By mixing drum structure points pear type, drum, double cone, the vertical shaft type disk and circular groove horizontal spindle type, etc

Description

Since the fall of mixer Has a long history, as early as the beginning of the 20th century, the drum of concrete mixer driven by a steam engine started to appear.After the '50 s, reverse discharging and tilting discharging the double cone mixer and cracked drum mixer appeared and development.Since the fall type concrete mixer mixing drum has a radial arrangement of agitating vane on the wall.Work, mixed tube around the horizontal axis of rotation, add mix the material inside the cylinder, after being up to a certain height by leaf, borrow gravity whereabouts, so the cycle of movement, to achieve the effect of even mixing.Since the fall type concrete mixer structure is simple, general is given priority to with mixing of plastic concrete.
Forced mixer Since the rise in the early 1950 s, obtained the rapid development and promotion.The first is the vertical shaft type disk forced concrete mixer.This mixer is divided into turboprop and planet type two kinds.After the 1870 s, with the application of lightweight aggregate, the circular groove horizontal-axis forced mixer, it divides single shaft and double shaft type two kinds, both the fall and forced the characteristics of two kinds of mixing.The mixing blade linear velocity is small, good abrasion resistance and less energy consumption, rapid development.Forced concrete mixer mixing tube inside the rotor arm frame equipped with mixing vane, add mix the material inside the drum, under the strong agitation of mixing blades, form a cross logistics.Fell this way of mixing than mixing way function strong, mainly suitable for mixing dry concrete.
Continuous concrete mixer Equipped with spiral mixing blades, all kinds of materials respectively according to the mixture after continuous weighing into blender, concrete mixture from the discharge end continuous discharge outward.This kind of mixer mixing time is short, high productivity, its developing compelling.
With the development of concrete materials and construction technology, and there appeared a lot of new type structure of concrete mixer, such as steam heating mixer, supercritical speed mixer, sound mixer, the swing of the mixing blade disc mixer and secondary mixing concrete mixer, etc.
