Abstract
The utility model discloses an automatic adjustable arc sieve support. The automatic adjustable arc sieve support comprises a fixed support (5) and is characterized in that a hydraulic rod (2) is arranged on the right side of the fixed support (5), the rear end of the hydraulic rod (2) is fixed on a convex block on the right side of the fixed support (5), the lower end of a connection seat of an arc sieve frame (1) is connected with the left side of the top end of the fixed support (5), the upper end of the connection seat of the arc sieve frame (1) is connected with the front end of the hydraulic rod (2), a transmission mechanism is arranged on the right side of the top of the fixed support (5), and the transmission mechanism is connected with a gear (6) on the periphery of a central rotating shaft of the connection seat of the arc sieve frame (1). The automatic adjustable arc sieve support solves the problems that operation wastes time and labor and has potential safety hazards, and maintenance is inconvenient due to the fact that an existing arc sieve support is difficult to lift and rotate.
Description
Technical field
The utility model relates to a kind of coal preparation plant sieve bend bearing, but the bearing of a kind of free lifting and the rotating curved sieve of automatic horizontal specifically.
Background technology
Sieve bend is as coal preparation plant's dehydration commonly used, de-mediated and cut thick equipment, by extensively practical.But compass screen surface weares and teares easily, needs often to change.When changing compass screen surface, because the sieve bend top is higher, the middle part is supported by fixed support, so need screen frame be set level and rotate to change compass screen surface by manually-operated.Not only waste time and energy, and have very big potential safety hazard, safeguard to execute-in-place to make troubles.
Summary of the invention
The technical problems to be solved in the utility model: a kind of automatic and adjustable sieve bend bearing is provided, wastes time and energy and exist potential safety hazard to safeguard problems such as inconvenience to solve operation that existing sieve bend bearing lifting and rotation difficulty cause.
Technical solutions of the utility model:
A kind of automatic and adjustable sieve bend bearing, it comprises hold-down support, on the hold-down support right side hydraulic stem is arranged, the rear end of hydraulic stem is fixed on the projection of hold-down support right side, sieve bend screen frame Connection Block lower end is connected with the hold-down support top left hand, sieve bend screen frame Connection Block upper end is connected with the hydraulic stem front end, in the hold-down support top right side transmission mechanism is installed, and transmission mechanism is connected with the gear of sieve bend screen frame Connection Block centre rotational axis periphery.
Transmission mechanism comprises motor and transmission worm screw, and motor is connected with the transmission worm screw, and the transmission worm screw is connected with the gear of sieve bend screen frame Connection Block centre rotational axis periphery.
The beneficial effects of the utility model:
The utility model not only can be simple, safe the free lifting sieve bend, and can realize the automatic rotation of sieve bend, improved the efficient of changing the sieve bend compass screen surface, ensured operator's safety; Having solved operation that the lifting of existing sieve bend bearing and rotation difficulty cause wastes time and energy and exists potential safety hazard to safeguard problems such as inconvenience.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
A kind of automatic and adjustable sieve bend bearing, it comprises (see figure 1) hold-down support 5, on hold-down support 5 right sides hydraulic stem 2 is arranged, the rear end of hydraulic stem 2 is fixed on the hold-down support 5 right side projections, the right side projection is positioned at the centre position of hold-down support 5, sieve bend screen frame 1 Connection Block lower end is connected with hold-down support 5 top left hand, sieve bend screen frame 1 Connection Block upper end is connected with hydraulic stem 2 front ends, sieve bend screen frame 1 Connection Block upper end is adopted hinged, the lower end adopts bearing to connect, in hold-down support 5 top right side transmission mechanism is installed, transmission mechanism is connected with the gear 6 of sieve bend screen frame 1 Connection Block centre rotational axis periphery, during hydraulic stem 2 front end pouring orifice (3) oil-feeds, the hydraulic stem withdrawal, pulling sieve bend screen frame 1 descends, during hydraulic stem 2 rear end pouring orifice (4) oil-feeds, hydraulic stem stretches out, promoting sieve bend screen frame 1 rises, realize the purpose of sieve bend screen frame 1 free lifting, transmission mechanism comprises motor 8 and transmission worm screw 7, motor 8 is connected with transmission worm screw 7, transmission worm screw 7 is connected with the gear 6 of sieve bend screen frame 1 Connection Block centre rotational axis periphery, when sieve bend screen frame 1 is reduced to level, motor 8 drives the gear 6 of transmission worm screw 7 and transmission sieve bend screen frame 1 Connection Block centre rotational axis periphery, realizes that sieve bend screen frame 1 can 360 degree rotations.
