Description
Technical field
The utility model relates to construction implement, especially relates to a kind of sieve for building.
Background technology
At construction site, often need before concrete spice to screen sand material, to avoid the even large-scale foreign material of river silt that adulterate in sand material, construction quality is had an impact.The screening of existing sand material mostly is screen cloth tiltedly to put to make screen cloth tilting, then manually spills to screen cloth by sand material, utilizes sand material to roll on compass screen surface under gravity, arrives the object of screening.Such screening process, the sand material amount that single spills to compass screen surface can not be too much, and spill be separated with certain restriction between compass screen surface, again could shed sand material when needing the sand material of compass screen surface to tumble totally, in case sand material is piled up affect screening effect.The consequence done like this is exactly the screening effeciency greatly reducing sand material, and then causes time-lag to construction.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of sieve for building, is to solve the not high problem of existing building sieve screening effeciency.
Its technical solution scheme is, comprise base and screen cloth, also comprise inverted truncated cone screen frame, screen frame is the hollow structure that upper end and waist open lower are provided with mounting disc, the waist of screen frame is made up of the first support column of multiple annular spread, said screen cloth uniform spreading is located on the inner surface of screen frame waist, and screen cloth is fixedly connected with the first support column; Center bottom screen frame is fixedly equipped with rotating shaft, and the lower end of rotating shaft is connected with motor by shaft coupling, and the bottom of motor is fixedly mounted on the upper surface of base.
The utility model structure is simple, convenient operation, utilize centrifugal force rule that assorted material is separated automatically with the grains of sand, grains of sand weight is greater than by the assorted material quality of sifting out, according to centrifugal force rule, centrifugal force suffered by the object that quality is large under same uniform velocity is greater than quality compared with the centrifugal force suffered by wisp, the edge of screen frame upper end slowly shifted to by assorted material in screen frame under the effect of larger centrifugal force, and finally depart from screen frame under the influence of centrifugal force, avoid the accumulation in screen frame of assorted material and affect screening effect, effectively can avoid assorted material blocking screen cloth, reach the object improving sand material screening speed.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 to 6, a kind of sieve for building, comprise base 1 and screen cloth 2, also comprise inverted truncated cone screen frame, screen frame is the hollow structure that upper end and waist open lower are provided with mounting disc 3, the waist of screen frame is made up of the first support column 4 of multiple annular spread, and said screen cloth 2 uniform spreading is located on the inner surface of screen frame waist, and screen cloth 2 is fixedly connected with the first support column 4; Center bottom screen frame is fixedly equipped with rotating shaft 5, and the lower end of rotating shaft 5 is connected with motor 6 by shaft coupling, and the bottom of motor 6 is fixedly mounted on the upper surface of base 1.
Said screen frame and screen cloth 2 material are metal, and screen cloth 2 is fixedly connected on the first support column 4 by screw.
The upper end of said rotating shaft 5 is exposed to the upper surface of mounting disc 3 and is provided with screw thread, the circumference place that rotating shaft 5 is exposed to mounting disc 3 lower surface is provided with the first step structure 7 that diameter is greater than rotating shaft 5 upper end, the upper surface of first step structure 7 contacts with the lower surface of mounting disc 3, the upper end of rotating shaft 5 is combined with clamp nut 8, forms the fixed connection structure of rotating shaft 5 and mounting disc 3.
The below of said mounting disc 3 is provided with protective plate 9, the bearing and protective plate 9 of rotating shaft 5 through being arranged at protective plate 9 center are formed and are rotationally connected, leave gap between the upper surface of protective plate 9 and the lower surface of mounting disc 3, protective plate 9 is fixed on the top of base 1 by the second support column 10 being evenly distributed on motor 6 periphery.
The upper surface of base 1 is provided with the second step structure 11 identical with protective plate 9 diameter, the periphery place of protective plate 9 and second step structure 11 is arranged with fence 12, the height of fence 12 is greater than the distance between protective plate 9 lower surface and base 1 upper surface, and fence 12 is fixedly mounted on the periphery of protective plate 9 and second step structure 11 by screw; The lower end of base 1 is provided with outstanding installation foot 13.
Its outer cover of said screen frame is equipped with the open hollow protection cylinder 14 in upper end, the upper surface of protection cylinder 14 is equal with the upper surface of screen frame, the lower end of protection cylinder 14 is provided with flange 15, flange 15 is fixedly mounted on the installation foot 13 of base 1 by screw, the barrel of protection cylinder 14 bottom offers multiple discharging opening 16, and the upper end of discharging opening 16 is lower than the upper surface of mounting disc 3.
