Description

Sand screening device

Technical Field

The utility model relates to a building construction equipment field, especially a screening sand device.

Background

The sand is a building material commonly used, can have impurity and the inhomogeneous phenomenon of granule after the sand is gathered and is accomplished, therefore the sand need sieve before using, and traditional screening sand device adopts the filter screen of an slope more, emptys the sand on the filter screen and utilizes self gravity to sieve through the filter screen mesh, and this kind of screening plant simple structure, the screening precision is low, and the screening effect is poor, still remains a large amount of fine sand in the sand that often does not pass through the screen cloth, causes the repeatability to operate.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a screening sand device, the effectual current screening sand device simple structure of having solved sieves the problem that husky effect is poor and need the rescreen.

The technical scheme for solving the problems comprises a platform, wherein two mutually hinged screen meshes are arranged above the platform, the front side and the rear side of each screen mesh are respectively hinged with a stand column which is slidably arranged on the platform, a polished rod which is fixed on the platform vertically penetrates through a pin shaft at the hinged positions of the two screen meshes, the pin shaft can slide up and down along the axis of the polished rod, a connecting rod is hinged on the pin shaft, a turntable is arranged below the pin shaft, the other end of the connecting rod is eccentrically arranged on the turntable, and a horizontal conveying belt which is fixed on the platform is arranged below the two screen.

The utility model discloses think about novelty, the structure is ingenious, and the practicality is strong, has effectually solved current screening sand device simple structure, and the screening sand effect is poor and need the problem of double screen.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

According to the drawings, the utility model discloses a platform 1, platform 1 top is equipped with two mutual articulated screen cloth 2, both sides respectively articulate around every screen cloth 2 has a slidable mounting stand 3 on platform 1, the epaxial vertical penetration of round pin of two screen cloth 2 articulated positions has a polished rod 4 of fixing on

platform

1, 4 axes of polished rod can be followed to the round pin axle and slided from top to bottom, it has connecting rod 5 still to articulate on the round pin axle, the below of round pin axle is equipped with a carousel 6, the other end eccentric mounting of connecting rod 5 is on carousel 6, the below of two screen cloth 2 is equipped with a horizontal conveyor belt 7 of fixing on platform 1.

In order to realize that the upright post 3 can be slidably mounted on the platform 1, a partition plate 8 is respectively mounted on the front side and the rear side of the horizontal conveying belt 7, the upright post 3 is arranged on the outer side of the corresponding side partition plate 8, a roller group 9 capable of sliding on the platform 1 is mounted at the lower end of each upright post 3, a sliding groove 10 is arranged at the outer end of each partition plate 8, and a sliding block arranged in the sliding groove 10 is arranged on each roller group 9.

In order to drive the rotating disc 6, a motor capable of driving the rotating disc 6 to rotate is arranged on the outer side of the rotating disc 6.

In order to achieve support of the screens and leakage prevention of the screens on the screens, a rectangular frame 11 is provided on the outside of each screen, and the screens are mounted in the rectangular frames 11.

The utility model discloses a concrete working process is: when the device is used, the rotary table 6 is firstly rotated to enable the two screen meshes 2 to rotate to be horizontal, sand to be screened is placed on the two screen meshes through manual or mechanical carrying equipment, the motor is turned on at the moment, the motor is enabled to rotate to drive the rotary table 6 to rotate, the rotary table 6 drives the hinged positions of the two screen meshes 2 to reciprocate through the connecting rod 5 at the moment, the polished rod 4 provides a positioning effect for the hinged positions of the two screen meshes 2, the screen meshes 2 on the left side and the right side can swing up and down under the supporting effect of the hinged upright columns 3 on the corresponding sides along with the rotation of the rotary table 6, the two screen meshes 2 can move left and right in the up-down swinging process, the upright columns 3 on the sliding mounting platform 1 can meet the left-right swinging of the screen meshes 2, screens on the screen meshes 2 can be screened fully through the up-down swinging of the screen, the screening sand device is convenient for collect through the conveying of conveyer belt, does not have behind the roving one end time of screen cloth 2 and when two screen cloth 2 hinge external lifting to the highest, shut down and follow the manual clearance of the low end position of screen cloth 2.

The significant benefits of the present device: this device realizes the reciprocal luffing motion of two screen cloth 2 that hand-over each other through a reciprocal drive structure for sand on the filter screen obtains abundant screening, has avoided the rescreen to improve the precision and the speed of screening simultaneously, sends out convenient collection through horizontal transfer area 7 after the screening is accomplished.
