Definitions
- the present invention relates to a machine for dispensing and spreading cement and similar powder-like material.
- the invention thus provides a machine for dispensing and spreading powder-like material, said machine comprising a vehicle supporting a hopper for containing said material, an outlet at the bottom of said hopper, a dispensing tray suspended on said vehicle below said outlet in a manner allowing limited movement and being adjustable to alter an angle of inclination of said tray relative to the horizontal, said tray extending to a rearward extremity of said vehicle for dispensing said material behind said vehicle as said vehicle moves forward, and means for vibrating said tray to cause said material to move along and off said tray.
- Fig. 1 is a side elevation of a machine according to the invention
- Fig. 2 is a part side elevation view similar to Fig. 1 on a slightly enlarged scale;
- Fig. 3 is a part rear view of the machine of Figs. 1 and 2;
- Fig. 4 is a part sectional side elevation of the machine showing the dispensing tray in a non-dispensing or stowage position
- Fig. 5 is similar to Fig. 4 but shows the tray in a dispensing position with rear flap opened.
- the machine 10 is in the form of a trailer having a single axle 11 and a pair of wheels 12.
- a frame 13 of the trailer incorporates a generally conventional trailer A-frame pull bar 14.
- the frame 13 rigidly supports a hopper 15 for containing cement and the hopper 15 has a outlet opening 16 which extends transversely across the trailer to provide an elongate relatively narrow bottom opening.
- a tray 17 for dispensing and spreading the cement is suspended from the frame 13 below the outlet opening 16 of the hopper 15.
- the tray 17 is suspended towards the front thereof by means of chains 18 which depend from a frame around the opening 16 of the hopper.
- the chains 18 are at each side of the trailer and connect to a flange at each side of the tray, respectively.
- Further chains 19 extend from a pulley 20 and attach to opposite sides of the tray 17 towards the rear extremity thereof.
- the tray 17 has upstanding sides 22 to contain the material on the tray and prevent it from discharging in a sideways direction. Likewise a lip 23 across the front edge of the tray 17 prevents the cement material from discharging from the forward end of the tray.
- a flap 24 extends across the rearward end of tray 17 and pivots on a shaft 25 which extends between the respective sides 22 of the tray. The downwardly depending flap 24 is actuated by a lever 26 from a closed position where it prevents material from being dispensed off the rear of tray 17 to an open position as shown in Fig. 5 where the cement material may be dispensed.
- the lever 26 is held in its various positions by a chain 27 which extends rearwardly from a connection point at the bottom of hopper 15.
- the chain 27 locks into a groove at the end of lever 26 and the lever is operated by lifting the chain 27 away from the lever until a new position is established in which case a link of the chain is then locked into the end of the lever.
- the flap 24 is spring loaded to the closed position.
- an electric solenoid (not shown) may be provided whereby the flap 24 is operated from within a towing vehicle to avoid the need for an operator to go to the rear of the trailer on regular occasions to open and close the flap.
- a molded cover 28 extends over the tray 17 in order to prevent moisture from entering the tray.
- the cover 28 fits over the sides 22 and extends from the hopper 15 to the rear most extremity of the tray 17.
- the cover also extends across the width of the hopper at the front bottom edge and overlaps the lip 23 of the tray again to prevent the ingress of moisture and also to prevent the cement material from escaping between the hopper and the tray.
- the flexibility of cover 28 allows alteration of the angle of inclination of the tray relative to the hopper.
- a rotary vibrator 30 is attached to the underside of tray 17 by means of a bracket 31.
- the vibrator 30 is driven by a shaft 32 via a universal joint 33 from a motor 34.
- the motor 34 according to this embodiment is a small four stroke internal combustion engine.
- the motor 34 is mounted on the pull bar 14 of the trailer. Rotation of the vibrator 30 causes a vibration in the tray 17 essentially in a fore and aft direction.
- a remote control (not shown) may be provided to allow an operator on the towing vehicle to alter the speed of the motor 14 to cause greater or less vibration of the tray with a consequent change in the rate of dispersion of cement.
- a tow ball 37 at the front of pull bar 14 allows the trailer to be connected to a motor vehicle such as a four wheel drive in order to transport and use the machine.
- the hopper 15 is firstly filled with cement which compacts within the hopper and remains therein during transportation despite the fact that the outlet opening 16 of the hopper remains open. Since some materials such as a mixture of cement and fly-ash do not compact sufficiently to remain in the hopper, a modification of the above described embodiment involves the provision of three gates or doors (not shown) in the bottom of the hopper 15.
- the gates are closed during transportation and opened when material is to be dispensed.
- the gates are arranged across the width of the trailer and may be selectively opened in varying degrees to adjust the rate of flow. This is particularly advantageous in situations where road camber tilts the trailer to one side causing the material on tray 17 to move to one side of the tray as it moves towards the rear.
- ribs or channels may be provided on the surface of tray 17 to extend in a fore and aft direction, that is, longitudinally, from adjacent the hopper to a position towards the rear of the hopper.
- the channels or ribs prevent sideways movement of the material.
- the inclination of tray 17 is changed from an essentially horizontal position to a position wherein it inclines downwardly towards the rear.
- the flap 24 is moved to an open position and the motor 34 is started in order to operate the vibrator 30.
- Vibration of the tray 17 causes the cement to move downwardly and rearwardly on the tray in a relatively even manner so that a wide dispersion of cement occurs behind the trailer. Since the outlet end of the tray is substantially the same width as the trailer a even spread of cement occurs as the trailer is towed along.
- the amount of cement discharged per unit area can be varied by altering the speed of the towing vehicle and/or the angle of inclination of the tray and this is a matter of judgement by the operator.
- the machine according to the present invention provides a convenient and efficient apparatus for dispensing and spreading cement and like materials.
- a particular embodiment has been described in detail it should be apparent to those skilled in the art that modifications to the described embodiment may be readily effected without departing from the scope of the invention.
- the covers 28 and 35 are formed of rubberised material in the described embodiment they could clearly be formed from sheet metal or other suitable materials, for example, provided sufficient flexibility is inherent in order to allow relative movement between the tray and the hopper.
- the machine is described as a trailer it could also be in the form of a vehicle having its own motive power. Other means besides chains could be used to suspend the tray 17 below the hopper 15 as it is only important that the suspension allows relative movement between the two.
