Description
Technical field
The utility model relates to the agitating device that a kind of constructional engineering machinery field is used, a kind of agitating device of concrete mixer specifically.
Background technology
Concrete generally refers to cement and makes Binder Materials, utilizes sand, stone and coordinates by a certain percentage with water, through stirring, moulding, maintenance and the cement concrete obtained.As one of main material of architectural engineering, concrete is widely used in building trade because of its good performance.
Concrete stirring is exactly cement, sand, stone and water to be mixed to also mixing become concrete mixture.Concrete stirring is generally used mixer to be operated, and at present, the use of horizontal horizontal axis forced mixer is comparatively general.Horizontal horizontal axis forced mixer mainly is comprised of stirring system, feed mechanism, device for discharging, water system, electric system, wherein stirring system is comprised of motor, decelerator, transmission device, agitating device and agitator tank etc., and agitating device mainly comprises the mixing arm that stirs arbor, stirring vane and connect stirring arbor and stirring vane.Agitating device is arranged in agitator tank, wherein stirring arbor is supported in agitator tank, on the stirring arbor, interval evenly is provided with the mixing arm vertical with the mixer shaft centre line, along the axial direction that stirs arbor, sees, mixing arm is arranged around stirring the arbor even circumferential along clockwise direction; The other end of mixing arm connects stirring vane.In whipping process, motor drives and stirs the arbor rotation by decelerator and transmission device, is fixed on the mixing arm and the stirring vane that stir on arbor and rotates simultaneously, and the mixed material in agitator tank is stirred.
Mixer is in whipping process, concrete easily sticks to and stirs on arbor, time has also been grown easily caking, usually after the concrete of thousands of cubic metres of normal productions, stirring arbor will be wrapped up by a large amount of concrete, and, along with the increase of output, stirring the concrete layer wrapped up on arbor can be more and more thicker.If continue, use the stirring arbor that is wrapped in concrete layer to carry out work, must spend the longer concrete mixing quality of mixing time guarantee, this just needs the more power of input, cause waste, concrete layer is blocked up simultaneously, the motor that also can cause mixer burns because of overload, has shortened the service life of motor, has improved production cost; If cleared up being wrapped in the concrete layer stirred on arbor not in time, can affect mixing effect, finally cause producing resulting concrete quality worse and worse.Want at present to remove and stir the concrete layer wrapped up on arbor, can only shut down manually and be cleared up: entered the narrow space of mixer inside by the staff, cut a hole clearly being wrapped in the concrete stirred on arbor.Because mixer inside is narrow and small very in a jumble, this labor cleaning's repair mode had both affected production efficiency, threatened again staff's personal safety.
The utility model content
The utility model technical issues that need to address are to provide a kind of agitating device of concrete mixer, and this apparatus structure is simple, can prevent that concrete setting is wrapped on the stirring arbor.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of agitating device of concrete mixer, comprise and be arranged on the stirring arbor that stirs in tank body, evenly be fixed in several mixing arms that stir on the arbor excircle, the stirring vane that is connected to the mixing arm end, also comprise and be sleeved on the some anti-ring of wrapping up in stirred on the arbor excircle, the described anti-annulus of ring for being made by screw-thread steel of wrapping up in, all arrange some pointed tooths on two ring end faces of described annulus.
Further improvement of the utility model is: the cross section of described pointed tooth is the isosceles obtuse triangle, some pointed tooths are along the anti-circumference uniform distribution of wrapping up in the ring end face of ring, the bottom surface of described pointed tooth is welded and fixed with the anti-ring end face of wrapping up in ring, and two central plane grindings of pointed tooth have cutting edge.
Further improvement of the utility model is: described pointed tooth is along preventing wrapping up in radially outward being obliquely installed of ring, and the angle between pointed tooth and ring end face is 30～90 °.
Further improvement of the utility model is: described pointed tooth is the conical structure be vertically set on the anti-ring end face of wrapping up in ring, and the bottom surface of pointed tooth is welded and fixed with the anti-ring end face of wrapping up in ring, and some pointed tooths are along the anti-circumference uniform distribution of wrapping up in the ring end face of ring.
Further improvement of the utility model is: described some anti-rings of wrapping up in are separately positioned between the two ends and adjacent two mixing arms of stirring arbor.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is simple in structure, at the anti-ring of wrapping up in stirred on arbor on the some ring end faces of socket with pointed tooth, when stirring the arbor rotation, driving the anti-ring of wrapping up in rotates, utilize the anti-stirring arbor of wrapping up in ring frictional impact rotation in whipping process, Automatic clearance sticks to the concrete stirred on arbor, prevented that concrete from wrapping up in the generation of axle phenomenon, reduced mechanical infringement, avoided shutting down the labor cleaning's process of carrying out, alleviated staff's labour intensity, shortened mixing time, reduced power loss, improved concrete mixing quality, saved production cost, improved production efficiency.
The anti-ring of wrapping up in utilizes screw-thread steel to be made, and utilizes the vertical rib of screw-thread steel surface irregularity and cross rib to strengthen the anti-ring of wrapping up in to concrete collision, prevents concrete parcel and solidifies.On the anti-ring end face of wrapping up in ring, some pointed tooths are set, and cutting edge is set on pointed tooth, fully concrete is broken up in cutting, has strengthened mixing effect, prevents concrete setting.
Pointed tooth is wrapped up in radially outward being obliquely installed of ring along anti-, and pointed tooth selects 30～90 ° with the angle of ring end face, prevents from making formation dead angle between pointed tooth and anchor ring and causing concrete to solidify in dead angle because angle is too little.
To prevent wrapping up in ring and be arranged between the two ends and adjacent two mixing arms of stirring arbor, and at whole, stir on arbor all evenly to be provided with and prevent wrapping up in ring, strengthen result of use, prevent that concrete setting is wrapped on the stirring arbor.
