Description

Multistage aggregate rotating vibrating screen

Technical Field

The invention belongs to the technical field of aggregate screening, and particularly relates to a multistage aggregate rotary vibrating screen.

Background

Aggregates are granular loose materials that act as a framework or fill in concrete. The aggregate is used as a main raw material in concrete and plays a role in skeleton and support in buildings. When the aggregate is mixed, the cement is stirred by water to be thin paste, if the aggregate is not added, the cement cannot be molded, and cannot be used, so that the aggregate is an important raw material in construction. The excessive or insufficient particle size of concrete aggregate can affect the quality of concrete products, and particularly the requirement on the particle size of the aggregate is strict when the characteristics of concrete are researched. The sieve device is divided as common multistage to the whirlpool, piles up on the fixed plate through the screen cloth that sieves different particle sizes, then places the board through the motor drive and waves according to circular orbit and sieve the aggregate, though possess better screening effect, nevertheless throw material and blowing and all need take off the screen cloth, use comparatively troublesome, and artifical burden is great.

Disclosure of Invention

Based on the problems mentioned in the background technology, the invention provides a multi-stage aggregate rotary vibrating screen which is used for solving the problems that the screen is required to be taken down when the rotary vibrating screen is used for feeding and discharging materials, the use is troublesome, and the manual burden is large.

The technical scheme adopted by the invention is as follows:

a multistage aggregate rotary vibrating screen comprises a base, wherein a placing plate is slidably mounted on the base, a stepping motor is mounted on the base, an eccentric frame is mounted on a rotating shaft of the stepping motor and hinged with the placing plate, a screen is stacked on the placing plate, a limiting groove is formed in the placing plate, a screw is mounted on the placing plate, a pressing plate is slidably mounted on the screw, an adjusting nut is mounted on the screw, a discharging channel is formed in the screen, a chute and a first lug plate are formed in the screen, a sealing plate and a limiting plate are respectively mounted on the inner wall and the outer wall of the screen, a connecting block is mounted between the sealing plate and the limiting plate and positioned in the chute, a top block and a second lug plate are mounted on the limiting plate, a tension spring is mounted between the first lug plate and the second lug plate, a feeding groove is formed in the pressing plate, a base is hinged on the base, and a mounting cavity is formed in the base, install first electric putter between base and the base, the second spout has been seted up on the base, slidable mounting has the push rod on the base, install second electric putter on the base, second electric putter is connected with the push rod transmission, base one side is installed and is retrieved the subassembly, retrieve the subassembly and include fixed connection place the seat and the spacing frame of U-shaped, evenly install on the spacing frame of U-shaped and bear the frame, bear and placed on the frame and retrieve the frame.

On the basis of the technical scheme, the invention also improves the following steps:

furthermore, the placing plate is provided with positioning frames, and the discharging channel is positioned between the positioning frames. The screen mesh is positioned by the positioning frame, and the position correspondence of the discharge channels on each screen mesh is ensured.

The placing plate can eccentrically slide on the annular bearing table, the placing plate can be axially limited while the sliding of the placing plate is not influenced through the annular limiting table and the second universal ball, and the step motor is prevented from being damaged due to the fact that the eccentric frame generates axial tension to a rotating shaft of the step motor.

Further, install the grooved rail on the base, slidable mounting has the slip table in the grooved rail, the push rod is installed on the slip table, install the transfer line on the slip table, second electric putter installs on the grooved rail, and fixed mounting has the connecting piece between second electric putter's telescopic link and the transfer line. The sliding table is limited through the groove rail, so that the sliding table is prevented from inclining, and further the situation that the ejector block cannot be contacted with the push rod due to the fact that the push rod arranged on the sliding table inclines is avoided.

Furthermore, a deflector rod is arranged on the adjusting nut. The adjusting nut is easier to rotate under the action of the deflector rod.

The invention has the beneficial effects that:

1. the stepping motor drives the placing plate to swing along the circumferential direction of the rotating shaft of the stepping motor through the eccentric frame, so that fine aggregates in each screen can be screened out quickly, and the screening efficiency is high;

2. waiting to sieve the aggregate and adding multistage aggregate rotation vibration sieve through the feed chute, through will placing the board slope and make the play material way on each screen cloth correspond with each recovery frame respectively when finishing screening and discharging aggregate in each screen cloth, promote the kicking block through the push rod by second electric putter at last and drive the shrouding and slide and open the screen cloth, aggregate in the screen cloth can be by row material way fall into by oneself in retrieving the frame, need not to demolish each screen cloth, reduce the human labor, it is comparatively convenient to use.
