The machine consists of a strong press-folded and electro-welded structure suitably stiffened in hot-dip galvanised carbon steel or in AISI 304/316 (on request).
The grid, made of steel plate with transverse ribbing, can be full height (on request). The end section is made of sheet metal to convey the material to the outlet
The rotation of the chain-driven shaft, and therefore the lifting of the cleaning rakes, is controlled by an oil-bath worm gear motor
The reed-holder chain can be adjusted by means of adjusters and rotates on steel sprockets mounted on grease chamber bearings
The steel drive shaft rotates on cast-iron supports
The hardened steel chains run on guides and rollers to facilitate their movement
The grating combs are made of steel with rotating torsional supports in the event of an abnormal body between the comb and the grating. The sliding part in contact with the grating is made of anti-friction material
OPTIONAL: electrical cabinet with IP 55/IP 65 protection rating is protected by rain cover
The rotation and relative ascent of the reed is protected against overloading by
dynamometric pendulum
Structure made of electro-welded pressed sheet metal of suitable size in galvanised or painted carbon steel or AISI 304/316 (on request).
Hinged on the structure is the carriage in which the comb-holding arm with cleaning comb slides.
The comb lifting and descent is controlled by an upside-down mounted hydraulic cylinder; sliding on the fixed grid first and on the conveyor plate afterwards, it discharges the screened material into the bin.
The downward and upward movement of the reed is controlled by hydraulic cylinders.
The movement system is served by a hydraulic control unit with overload protection.
The electrical panel controlled by PLC ensures the sequence of operations.
The work pause time is managed by a timer regulated by the operator.
Base structure in press-folded and electro-welded sheet metal to make the structure rigid and homogenous in galvanised carbon steel or AISI (on request).
On the inside, on appropriate crossbeams, the hydraulic power pack unit is housed.
The control unit is accessible via an opening panel.
The guide and grating unit are hinged to the upper part of the structure with hydraulic tilting.
The reed carriage slides on moulded wheels made of self-lubricated MTA 22 material.
The comb consists of perforated, shaped sheet metal bolted to the comb carriage guide rails.
At the end is a plastic MTA 22 material strip with teeth to penetrate into the fixed grating spaces for improved cleaning.
The fixed grating is made of carbon steel plate of a suitable size with a clear span as requested by the customer.
The hydraulic control is managed by a hydraulic power unit of adequate power with double gear pump and solenoid valve unit with hydraulic system against abnormal overloads.
The IP 55/IP 65 electrical panel mounted on the machine is managed by a PLC with manual-automatic program with fixed push-button panel on a wall-mounted panel on request.
The construction can be arm-mounted with double guide for long channels and heavy-duty work, or single arm for smaller channels.
For wide channels, the system can be translating with a base carriage sliding on rotating wheels on rails.
For reduced overall height, the chute arm can be of the TELESCOPIC type with double extension cylinder
