Abstract

The utility model discloses a mechanical type arc-shaped screen automatic turning mechanism which comprises a support base. A box body is arranged at the top end of the support base in a sliding mode. A worm wheel device is arranged in the box body. A connecting disc outside the box body is connected with a wheel shaft of a warm wheel. The connecting disc is connected with an arc-shaped screen. An electric-hydraulic pusher device is arranged at a side of the support base in the sliding mode. The electric-hydraulic pusher device comprises a motor and a pusher. The top of the pusher is connected with the outer side of the box body in the sliding mode. The support base is further provided with a limit switch. According to the mechanical type arc-shaped screen automatic turning mechanism, automatic turning of the are-shaped screen is achieved through adoption of the electric-hydraulic pusher device and the worm wheel device, and therefore a large amount of labor is saved. In addition, due to arrangement of the limit switch, the mechanism can be stopped when reaching a station so that the mechanism is enabled to be safe, stable and reliable in use.

Description

Mechanical type sieve bend automatic turning mechanism

Technical field

The utility model relates to sieve bend, relates in particular to a kind of mechanical type sieve bend automatic turning mechanism.

Background technology

De-mediated for Recognition Applied in Coal Preparation System fine fraction coal slime, dehydration and desliming, a kind of upset sieve bend of commonly using at present, that arc screening plate is fixedly installed on the screen box, screen box is by upright supports, under the duty, the screen box bottom surface is horizontal by 45 degree to 60 degree inclination angles, in order to satisfy the requirement of production technology, and the service life of improving as far as possible screen cloth,, after washing away after a while, need to screen cloth Rotate 180 degree in the plane at screen box place, continue again to use at screen cloth, at present, the method of operating of this rotary course is at first to use manpower, approximately needs 8 to 15 people, and screen box is spent to the 60 inclination angle state turnovers of spending to horizontal level from 45 together with arc screening plate, then screen box and arc screening plate could be carried out the rotation of 180 degree, finish after the rotation, re-use manpower, with screen box and together with the arc screening plate reverse flip it is recovered at 45 degree to the use state at 60 degree inclination angles, whole operating process is both dangerous, wastes time and energy again.

The utility model content

The utility model purpose is exactly in order to remedy the defective of prior art, a kind of easy to use and safe and reliable mechanical type sieve bend automatic turning mechanism to be provided.

The utility model is achieved through the following technical solutions:

A kind of mechanical type sieve bend automatic turning mechanism, include bearing, described bearing top is slidingly fitted with casing, gear is arranged in the casing, in the casing outside and link to each other with the worm gear wheel shaft terminal pad arranged, described terminal pad connects sieve bend, the worm gear wheel shaft rotates the rotation of drive sieve bend by driving terminal pad, described bearing side slip is equipped with the Electrohydraulic push rod device, described Electrohydraulic push rod device includes motor and push rod, the top of described push rod and described casing outside slip are dynamically connected, promoting casing by push rod swings and drives sieve bend and swing, limit switch also is installed on the described bearing, and the realization sieve bend puts in place and namely stops, and makes it safe and reliable.

Described mechanical type sieve bend automatic turning mechanism is characterized in that: be furnished with removable connector on the described terminal pad, to adapt to the connected mode of various different model sieve bends.

Described mechanical type sieve bend automatic turning mechanism, it is characterized in that: described bearing is the combined steel bearing, and is more firm when making its work.

Operation principle of the present utility model is: starter motor, make the push rod down sliding, drive casing and move on to horizontal level, namely sieve bend also moves on to horizontal level, starts worm gear and makes its rotation, terminal pad drives sieve bend and rotates together, when sieve bend rotation 180 is spent, stop worm gear and rotate, at starter motor, make the push rod upward sliding, drive casing and sieve bend and get back to former incident angle.

The utility model has the advantages that: the utility model has used voltage push rod device and gear to realize the automatic turning of sieve bend, saved a large amount of manpowers, this device also is provided with limit switch in addition, and realizing puts in place namely stops, and makes it more secure when used solid and reliable.
