An embodiment of the invention will now be described with reference to the accompanying drawing showing a schematic view of a machine.
Referring to the drawing there is shown a mobile concrete mixing machine 1. Machine I is controlled by a computer 10 as more fully described belov.
Machine I has a conveyor 0 leading to a concrete mixing chamber 30. Conveyor At) is powered he an hydraulic motor HI which is controllable by the computer Conveyor speed ontrol' I I to driv: the;nnvcor.i! cars ma; Speeds. conveyor speed sensor 9 is prodded cnuccled to to ,mpuler cI'r!/ev,r Spt.;"i sensor I - to SenSL' the speed of the t On\ ever.

A stone hopper 50 is provided having a controllable stone outlet in the term of a flow control gate 51 to deliver stone at varying flow rates onto the conveyor. Flow control gate 51 is controllable by the computer stone flow control" 15. - s
A cement hopper 60 is provided having a controllable cement outlet in the forth of an Archimedes screw 61 rotated by an hydraulic motor 62. Motor 62 is controllable by the computer "cement flow rate control" 16 to drive the conveyor at varying speeds to deliver cement at varying flow rates into the mixing chamber 30. A sensor 63 is provided connected to the computer "cement flow rate sensor" to sense the rate of flow of the cement, and the computer adjusts the flow rate when the rate sensed is greater or less than a desired rate.
A water hopper 7() is provided having a controllable water outlet in the form of an hydraulic motor driving water pump 71. l he speed of pump 71 is controllable by the computer rewater flow rate control'M 8 to deliver water at varying flow rates into the mixing chamber 3(i. . sensor 72 is provided connected to the computer Mater flow rate sensor 19 to sense the rate,I flow ot waler, and the computer ad lusts the flow rate when the rate sensed is greater or less than a desired rate.
Mixing chamber 30 includes a mixing Archimedes screw 31 which leads to a delivery means in the form of aperture 32 to deliver mixed concrete from the mixing chamber.
In use said flow rates of the sand, cement, stone, and water are controlled by a user, along with the speed of the conveyor, in order to create concrete with any desired ratio of sand, cement, stone, and water. It is envisaged that computer 10 has a database of set concrete recipes each with a different ratio of sand, cement, stone, and water, and a set conveyor speed. The computer then controls the flow rates of the sand, cement, stone. and water according to a recipe selected by a user.
I'hc concrete mixer my Further include one or more. cog. two. concrete additive containers (not shoving to deliver addtivcs to the mixim, chamber I'refUraklv the computer further controls the troy rate ot'anv aL, ditves into the mixhg chamber. , sensor may he provided comcccd to tl.c computer lo.:nsc rh. rat: o' loo,i'an\ additives. and the compoitn ad lusts the llo\\ r:!te hen the rate uns.i Is,rc;.er Or less!hun a dcsireL1 rate. I'rcterahly any additives are delivered by an electric fir pneumatic slump.
It will be appreciated that if the conveyor should slow down from an expected speed set by the computer. em due to overheating ot'the hydraulics. then the sensor will sense this and the motor 2I will be controlled to run taster. The same applies to the flow rates of the cement and water. It is envisaged that the sand and stone flow control gates will be shutters which can each be opened to a varying extent to a given aperture size by the computer to give a required flow rate based on a gravity feed. If desired sensors connected to the computer could be provided to sense the position of the sand and stone gate shutters so allowing the computer to control accurately the -)

sand and stone flow control gates. One or more vibrators may also be provided to assist the | v;ry:1, and the vb=m may be: tuned on Larva s by the computer In a simple form of the invention, the computer could be omitted and the flow rates of the sand, cement, stone, and water (and optionally the speed ofthe conveyor) could be adjusted manually.
It will be appreciated that by controlling the flow rate of the cement (rather than having this fixed as in the prior art), so the amount of concrete produced can be kept higher when producing a strong mix.
It will he appreciated also that the control of the flow rates of the sand, cement. c. and evader (and optionally the speed ot the conveyor), so the energy used to power the macl,ue can he optimised.
The invention may take a form different to that specifically described above.
Further modifications will be apparent to those skilled in the art without departing trom the scope of the present invention.
