Abstract

The material spreader comprises a wheeled chassis 1 with a material container 2 being tiltable to feed material onto a vibratory plate 3 whereby it is fed to the rotary spreading disc 5 which discharges the material out of the spreader. A metering gate 4 is provided to prevent the movement of material into the spreading disc 5 during transport to a field and to meter the flow of material to the spreading disc 5 during operation so that materials having a variety of consistencies may be spread. The rotation speed of the spreading disc 5 is also variable to cater for a variety of materials. <IMAGE>

Description

MULTI MATERIAL DISCHARGE UNIT This invention relates to a Multi Material Discharge Unit. (Referred to as M.M.D.U. hereafter).

Bulk material spreaders are machines well known in many industries and are used for spreading a variety from dry solid to wet slurry type materials.

Present bulk material spreaders are however sometimes complicated machines which are not suited to evenly spreading both dry solid and wet slurry type materials without modifications. They are also prone to problems caused by foreign matter clogging the spreading mechanism (e.g.

stones, wood etc.,) Some types of machine also have high power requirements to spread the materials.

The present invention simply comprises a container which holds the material to be spread, a vibrating screen, a metering gate and a rotating disc which shreads and discharges the material.

An example of the invention will be described with reference to the accompanying drawings.

Figure 1 - Shows the M.M.D.U. side view comprising: 1 - wheeled chassis 2 - half tilting material container 3 - vibrating screen 4 - metering gate 5 - rotating disc Figure 2 - Shows the M.M.D.U. rear view and direction of discharged material. (Itemised details as above) Figure 3 - Shows the M.M.D.U. top view and direction of discharged material. (Itemised details as above) Figure 4 - Shows the M.M.D.U. side view in the spreading mode with metering gate open and body tipped. (Itemised details as above) To operate the machine the metering gate (4) is closed to prevent leakage of material. The machine is then loaded with the material to be spread.

The machine is then taken to a place where the spreading is to take place.

The rotating disc (5) is set in motion to the required speed.

The metering gate (4) is then opened to the required amount and material spreading can then commence.

The meturing gate (4) call bu adjusted in order to achieve an jccuplablu spread rate and pattern.

Claims (5)

1. A M..D.U. comprising a wheeled chassis, a half tilting material container, a vibrating screen, a metering gate and rotating disc.

2. A M.M.D.U. which will spread both dry solid type material and wet slurry type material with only simple field adjustments i.e. adjust rotating disc speed and metering gate opening.

3. A M.M.D.U. that will not be prone to blockages by foreign objects i.e. stones, wood etc.,

4. A M.M.D.U. that will with simple field adjustments give a wide and consistent spread of material with high spreading capability.

5. A M.M.D.U. that is simple in design and construction, simple to operate with a low power requirement.
