Description

The drum-type sand sieving machine

Affiliated technical field

The utility model relates to the building machinery technical field, relates in particular to a kind of drum-type sand sieving machine that is used for construction sieve sand.

Background technology

At present, known construction sieve sand is sand to be shed on the sieve that tilts to support by an artificial spade spade ground, utilize the sieve that focuses on certainly of sand to go up downward landing, realize sieve sand, if but such landing process sand too much many damp sands of well sifted, especially water content fully of the amount of shedding once, in addition, backstage feed personnel need consume the entrucking manpower again one time, and occupied ground to be gone back in the stacking of finished sand again with the finished sand entrucking.

Summary of the invention

In order to solve existing artificial sieve sand because of using simple tool and falling behind the low work efficiency problem that construction method is caused, the drum-type sand sieving machine that the utility model provides, mechanical picker sand, finished sand can directly install on the heater car, use by backstage feed personnel, with using, full-time sieve sand personnel have been saved, the stacking place of also having saved finished sand with sieve.

The technical scheme in the invention for solving the technical problem is: it is by transmission mechanism, rotary screen, and sand material hoisting mechanism is formed; It is to be rotated by the big belt wheel of driven by motor for described transmission mechanism, big belt wheel drives coaxial mounted three sprocket rotation again, wherein two sprocket wheels drive two rollers rotations of rolling and contacting with rotary screen by chain respectively, being provided with the rolling ring circumference contact-making surface frictional force of utilizing roller and rotary screen in the rolling ring that pinch roller is pressed in rotary screen rotates rotary screen, the sand material spills from screen cloth in the rotary screen thereby make, and realizes sieve sand.It is by rotating by the roller that chain drives hoisting mechanism with coaxial mounted another sprocket wheel of aforementioned big belt wheel for described sand material hoisting mechanism, and the traction belt that is provided with hopper is centered around on the roller, and hopper is along with the rotation of the traction belt rotary movement that raises continuously.Hair sand is packed into by an end of rotary screen, being provided with baffle plate in the rotary screen can make mao sand be contained in the interior position initially to be sieved of rotary screen, being fixed with the inside spin leaf in the rotary screen can be discharged slag charge by the rotary screen other end, the finished sand that is leaked down by screen cloth drops on the sand material elevator hopper, and the elevator hopper is raise to overturn by the adhesive tape traction material is unloaded onboard.

The operation principle of drum-type sand sieving machine is: open motor and rotate, drive sand material hoisting mechanism and rotary screen simultaneously and rotate, manually feed in rotary screen continuously, finished sand is by the entrucking of sand material elevator.

The beneficial effects of the utility model are: only need the manually i.e. realization sieve sand entrucking of charging in rotary screen continuously, and sieve sand efficient height, this machine is used by backstage feed personnel, with using with sieve, saves full-time sand personnel of sieve and finished product stockpile and puts the place.
