0/01 12 215191 AUSTALIARegulation 3.2 Patents Act 1990 ORIGINAL 6 8 2 COMPLETE SPECIFICATION PETTY PATENT Invention Title: sys m T0: he following statement is a full description of this invention, including the best :::method of performing it known to me:- 0o* consistent.w mele otq de~lwig man~ n t. eny yt otnp e. t.Q8.etel outlets caused by variations in the amount of exposure of the fluted roller 4;15 1 1. 0. this metering system overcomes thle problem by ensuring each outlet has even exposure to the metering system, conventional granular metering systems are 0. 5. often unable to meter the last 10-20% of the granular material this invention overcomes the problem having the ability to accurately meter almo~st the entire o1 volume of granular/particle substance, conventional granular metering systems are generally very awkward and time consuming to clean at the completion of the job the this metering system has a curved trap door across the entire width of the hopper which swings open at the canpletion of the job allowing it to automatically self ckanm, after cleaning the trap door is swung back into position ready for further use or storage and this inrvention should prove to be less expensive to produce than conventional granular/particle metering systems To assist with understanding the invention, reference will now be made to the accompanying drawings which shows an example of the invention.

Close fitting lid protects contents from the elbments, hopper (2) capacity designed to suit application and makes extensive use of full profile baffle plates (10) to maintain accurate metering rates of granular/particle substances when angle of operation varies from level, rotating fluted roller flutes cut either parallel to axis or cut spirally to guard against pulsing, maintain consistent metering rate from the entire width of hopper fluted roller is interchangeable allowing for a change of grain/particle 10 size and metering rate, changing the speed of rotation of the fluted roller is also an option to alter metering rate, metered flow falls a short distance onto parallel divider head automatically dividing flow evenly into desired number of outlets, granular/particle material may be gravity fed to desired point of delivery or air assisted delivery hoses are 15 attached directly to the bottom of parallel divider head and transports metered material to the point of delivery, use of a hinged curved trapdoor across entire width of hopper allows for final cleaning at the *05500 a completion of job, the hinged curved trapdoor also plays an important role in the control of the metering rate by varying the clearance between S* 20 hinged curved trapdoor and fluted roller clearance set between hinged curved trapdoor and fluted roller also prevents self feeding of the granular/particle material, the rear section of the hopper is sealed using a thin pliable flap which acts as a seal to prevent uncontrolled flow of granular/particle material from the rear of the hopper and side plates of hopper are folded 90% at the bottom and act mounting points for the invention allowing for easy attachment to scarifiers, combines and other types of stationary or mobile equipment which requires the use of an accurately granular/particle area or location at a predetermined rate and uses flange mounted self plumbing bearing to ensure ease of rotation and accurate positioning of fluted roller (3) C.
