Aardvark M.T. 14 G.C. gravel cart with internal auger
Developed initially for use with C.B.S. product (Cement Bound Sand) used for bedding & blinding over electric cables in major U.K. infrastructure projects, Aardvark Equipment Ltd. have recently introduced the M.T. 14 G.C. I.A.. model.
Powerful 500MM DIAMETER AUGER, RATED AT 1800NM TORQUE "CHURNS" C.B.S.
The internal hopper auger uses a 6 tonne capacity hydraulic rotator unit usually found in the timber harvesting & brick grab industries, rated at 1800Nm rotational torque connected to a 500mm diameter x 400mm pitch auger with a 10mm flight thickness, with the whole unit being suspended inside the hopper on a "web" of 5 tonne breaking strain industrial chains.
The hydraulic rotator is connected to an auxiliary tractor spool & when activated from the tractor cab, heaves the C.B.S. mix vertically up from the "throat" of the gravel cart hopper upwards towards the top of the hopper. At 3 to 4 r.p.m., the auger is capable of recirculating around 0.3cubic metres/minute of C.B.S. product & preventing any "bridging" that may occur when using C.B.S. in a standard cart.
The unit is particularly successful when used in conjunction with a 12v vibrator unit mounted on the outside of the hopper & the 20 degree conveyor tilt mechanism which creates an air void under the hopper material when activated.
These three attributes when combined create a robust "armoury" to guard against stubborn material flow.

12V HOPPER VIBRATOR12V electric vibrator runs from tractor battery on a 25% duty cycle, oscillating the left hand sloping hopper wall, forcing C.B.S. to tumble down to hopper/conveyor "throat" area.
using all three hopper agitation mechanisms ensures positive c.b.s. flow even on damp days. |
CONVEYOR FULLY TILTED AT 20 DEGREESThe conveyor can be raised from 0 degrees (horizontal) position through 20 degrees during hopper discharge cycle. Each upwards nudge of the output end of the conveyor creates a small air void in the bottom of the hopper, as the innermost part of the conveyor tilts downwards. Every nudge of the hydraulic tilt mechanism moves the conveyor 2 or 3 degrees, so during a full hopper discharge 8 - 10 nudges are available before the conveyor is fully elevated. The air voids are immediately filled with C.B.S. as it tumbles into the hopper base.
