Description

Unpowered belt sweeper

Technical Field

The invention belongs to the field of mechanical application, and particularly relates to the field of belt surface cleaning of a belt conveyor.

Background

Belt conveyors typically employ non-metallic squeegees or powered brush rollers for belt surface cleaning. The scraper blade is easy to wear due to friction with the belt, certain damage can be caused to the surface of the belt, particularly a belt interface, the power brush roller needs a motor and a speed reducer to drive, and electric energy is consumed in the operation process.

The technical scheme adopted by the invention for solving the technical problems is as follows: an unpowered belt sweeper comprises a brush roll, a driven sprocket, a chain, a swing arm, a driving sprocket, a smoothing roll, a pneumatic control system, a clamping plate, a support and a belt conveyor support, wherein the support and the clamping plate are clamped on the belt conveyor support through fastening bolts; one end of the pneumatic control system is connected with the support, and the other end of the pneumatic control system is connected with the swing arm; a first bearing with a seat is arranged on the support, and a second bearing with a seat and a third bearing with a seat are arranged on the swing arm; two ends of the smooth roller penetrate through the first bearing with the seat and the second bearing with the seat, and the smooth roller is pressed on the belt; two ends of the brush roll penetrate through the third bearing with the seat; the driving chain wheel is locked at one end of the smooth roller, the driven chain wheel is locked at one end of the brush roller, and the chain is connected with the driving chain wheel and the driven chain wheel.

The following are preferred technical solutions:

the sweeper further comprises a limiting bolt, and the limiting bolt is screwed on the support and is used for adjusting the contact pressure between the brush roller and the belt.

The sweeper further comprises a tensioning bolt, and the tensioning bolt is installed on the swing arm and used for adjusting the tension degree of the chain.

The sweeper further comprises a baffle, and two ends of the baffle are connected with the swing arm through bolts.

The sweeper further comprises a protective cover, the protective cover is installed on the swing arm, and the driven chain wheel, the chain and the driving chain wheel are all installed in the protective cover.

The driven chain wheel and the driving chain wheel are locked on the smooth roller and the brush roller in an expansion sleeve mode.

Compared with the prior art, the invention has the following beneficial effects:

(1) the unpowered driving of the brush roller can be realized: when the conveyor is started, the belt drives the smooth roller to rotate, the smooth roller drives the driving chain wheel to rotate, the chain drives the driven chain wheel to rotate, and the driven chain wheel drives the brush roller to rotate, so that extra electric drive is not needed.

(2) The brush roll contact pressure is adjustable during operation: when the conveyer starts, the pneumatic control system enables the piston rod of the single-acting cylinder to drive the swing arm to swing, so that the brush roller is in contact with the belt to be cleaned, the limit bolt is adjusted according to the dust sticking degree of the belt to adjust the contact pressure of the brush roller, and the belt is effectively cleaned.

(3) Brush roll contact zero pressure when shutting down: when the conveyor stops running, the upper cavity of the single-action cylinder is communicated with the atmosphere, the swing arm swings downwards due to the weight of the brush roll, the brush roll is separated from the belt, and the permanent deformation caused by local pressure when the bristles are static is avoided, so that the cleaning effect is influenced, and the service life of the bristles is prolonged.

(4) The chain tension is adjustable: the tensioning bolt is adjusted to enable the chain to reach reasonable tension, transmission efficiency is guaranteed, and abrasion and jumping of the chain wheel are effectively reduced.

(5) Protecting chain transmission parts: after the driven sprocket, the chain and the driving sprocket cover the protective cover, safety accidents can be effectively avoided during operation, and the dust is prevented from adhering to the sprocket and the chain.

(6) The sprocket is easily dismantled and assembled: the driven chain wheel and the driving chain wheel are locked on the smooth roller and the brush roller in an expansion sleeve mode, and the installation and disassembly time is short and the efficiency is high.

(7) The brush roller is protected against dust: the baffle can block the dust that the belt was unloaded when flying, avoids the too much dust of brush hair adhesion.

(8) Emergency operation guarantee: when the pneumatic control system or the single-acting cylinder failure can not be solved at once, the single-acting cylinder can be detached, the straight rod is used for replacing the single-acting cylinder to connect the support and the swing arm, and the brush roller is guaranteed to continue to work.
