    A conveyor (20)is arranged to be mounted underneath a hopper bottom 5 highway transportation truck (10) which has two longitudinally spaced dump hoppers (11, 12) each with a bottom discharge opening (13, 14) to carry the discharged material to the side of the trailer from each of the hoppers in turn. The conveyor is thus carried between the bottom discharge openings so that it can be raised up between them during transport. From the mounting point (34) at one 10 side between the openings the conveyor (20) is lowered so that its loading end (21 B) is lowered and then the conveyor pivots to one side or the other so that its loading end is underneath the selected bottom discharge opening. The conveyor runs in a direction so that it lifts the material from the selected discharge opening upwardly to the mounting point at the one side for discharge to the side. -~ m * I C) I4-~ 7 _ I' I N) ~- /-~*

    CONVEYOR FOR HOPPER BOTTOM TRANSPORTATION VEHICLE This invention relates to a conveyor arranged to be mounted underneath a 5 hopper bottom transportation vehicle with two dump hoppers and pivotal to two different positions to carry the discharged material to the side of the vehicle from each of the hoppers in turn. The reference to prior art in this specification is not and should not be taken as an acknowledgment or any form of suggestion that the referenced prior art 10 forms part of the common general knowledge in Australia or in any other country. US Patent 2,564,020 (Mengel) issued August 14 1951 discloses a conveyor carried on a carriage which moves along the trailer to the different discharge outlets. US Patent 4,586,865 (Hansen) issued May 6 1986 discloses a conveyor 15 mounted at the discharge of the hopper and rotatable about a vertical axis at the discharge. These arrangements are concerned with the same problem as that of the present invention but provide an unsatisfactory solution and could not be used with current equipment. 20 The present invention is particularly concerned with discharge of seed from the hoppers of a highway trailer for loading a seeder so that protection of the product discharged from the hoppers to avoid wastage is a particular concern. However the conveyor can be used for discharging any particular flowable product from the hopper bottoms of any transport vehicle. 25 In the specification the term "comprising" shall be understood to have a broad meaning similar to the term "including" and will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. This definition also applies to variations on the term "comprising" such as "comprise" and 30 "comprises". 1 SUMMARY OF THE INVENTION It is one object of the present invention to provide a conveyor arranged to be mounted underneath a hopper bottom vehicle transportation vehicle with two 5 dump hoppers to carry the discharged material to the side of the vehicle from each of the hoppers in turn. According to one aspect of the invention there is provided a conveyor arranged to be mounted underneath a hopper bottom transportation truck vehicle which has two longitudinally spaced dump hoppers each with a bottom discharge 10 opening, the conveyor being arranged to carry the discharged material to the side of the trailer from each of the hoppers in turn, the conveyor comprising: a conveyor frame arranged for mounting on the vehicle; a conveyor mechanism on the frame having a discharge at a first end of the frame and a feed receptacle at a second end of the frame; 15 a mounting arrangement for mounting of the first end of the frame at or adjacent a first side of the transport vehicle at a position between the two hoppers; an attachment assembly for releasable attachment of the second end of the frame at or adjacent a second side of the transport vehicle at a position between the two hoppers; 20 such that in a transport position the frame extends across the vehicle and is carried by the mounting arrangement and the attachment assembly in a position between the two hoppers extending across the vehicle; the attachment assembly being arranged to release the second end of the frame to lower from the vehicle to the ground; 25 the mounting arrangement being arranged to allow up and down pivotal movement of the frame so as to allow the second end to raise and lower to the ground; the mounting arrangement being arranged to allow pivotal movement of the frame about a generally upright axis at the first side; 30 such that in a first operating position the frame pivots so that the feed receptacle is located underneath a first one of the bottom discharge openings; 2 and such that in a second operating position the frame pivots so that the feed receptacle is located underneath a second one of the bottom discharge openings. Preferably the frame is arranged in the operating positions such that the 5 conveyor runs in a direction so that it lifts the material from the selected discharge opening upwardly to the mounting point at the first side for discharge to the side of the vehicle. Preferably the frame is horizontal in the transport position and the frame extends to a height no lower than the bottom of the discharge hoppers in the 10 transport position. It is necessary in highway trailers for which the present arrangement is particularly designed that the ground clearance defined by the bottom of the hoppers is not compromised by low hanging elements. Thus the present arrangement, as determined by the inventor can extend across between the two hoppers without presenting any low hanging obstacle. The length which 15 matches the width of the vehicle also allows the feed receptacle at the second end to reach to the two hoppers only by pivotal movement of the frame about the mounting at the first side. The second end of the frame can include an optional a ground wheel or other element which allows the required movement in an arc around the generally 20 upright axis. However the movement can also be effected by a lifting handle which takes sufficient weight to avoid the necessity for a wheel. Preferably the second end of the frame is lifted manually and there is provided a spring assist for providing an assisting lifting force lifting the second end of the frame. However a winch or other lift arrangement can also be provided. 25 Preferably the feed receptacle comprises a hopper. Preferably the conveyor is a belt but other arrangements such as an auger can be used. Preferably the conveyor is arranged so that the discharge is located at the first side underneath the mounting arrangement so as to discharge at the side of 30 the vehicle with no extension portion. Typically this discharge directly at the side can fall direction into a feed conveyor of an air seeder without providing any extensions of either the conveyor itself or that of the air seeder. This allows a conventional simple air seeder conveyor to be used which simply moves to one 3 side of the air seeder and avoids the hopper of the conveyor from being located underneath the vehicle where it can be damaged if suitable care is not taken. The conveyor is thus carried between the bottom discharge openings so that it can be raised up between them during transport. 5 From the mounting point at one side between the openings the conveyor is lowered so that its loading end is lowered to a transport wheel and then the conveyor pivots to one side or the other so that its loading end is underneath the selected bottom discharge opening. The conveyor runs in a direction so that it lifts the material from the 10 selected discharge opening upwardly to the mounting point at the one side for discharge to the side. The prior art does not operate in this way and could NOT operate with modern hopper bottom highway transportation trucks. One embodiment of the invention will now be described in conjunction with 15 the accompanying drawings in which: BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a side elevational view of a hopper bottom highway transportation vehicle including one embodiment of a conveyor according to the 20 present invention shown in the transport position. Figure 2 is a side elevational view of the vehicle and conveyor of Figure 1 in the operating position. Figure 3 is a rear elevational view of the conveyor of Figure 1 in the transport position. 25 Figure 4 is a rear elevational view of the conveyor of Figure 1 in the operating position. Figure 5 is a top plan view of the conveyor of Figure 1 in the operating position at one hopper. Figure 6 is a top plan view of the conveyor of Figure 1 in the transport 30 position. Figure 7 is an isometric view of the conveyor of Figure 1 in the transport position. 4 Figure 8 is an isometric view of the conveyor of Figure 1 shown in the operating position DETAILED DESCRIPTION 5 In the figures is shown a hopper bottom highway transportation vehicle 10 which has two longitudinally spaced dump hoppers 11 and 12 each with a bottom discharge opening 13, 14 mounted on ground wheels 15 for transportation from a supply location to a discharge location. The vehicle is shown as a trailer but can be self-propelled. The vehicle is shown for highway use but can be a farm type 10 vehicle. A conveyor 20 is arranged to be mounted underneath the vehicle between the two hoppers 11 and 12. The conveyor includes a conveyor frame 21 defined by side members 22 and end cross members 23 so as to provide a rigid structure arranged for 15 mounting on the vehicle. A conveyor belt 25 is carried on the frame by rollers 26, 27 and is driven longitudinally of the frame to define a discharge 28 at a first end 21A of the frame and a feed receptacle 29 or hopper with walls 30 at a second end 21 B of the frame 21. 20 A mounting arrangement 34 comprises a rail 34A which extends transversely across the vehicle from a first end 34B at one side rail 10A of the vehicle to a second end 34C at the opposed side rail 1OB of the vehicle. The rail 34 is carried on straps 34C and 34D connected between the hoppers 11 and 12 so as to hold the rail 34 at a position between the hopper at a position below the 25 main fame of the vehicle. The straps can be arranged to allow movement of the rail 34A longitudinally of the vehicle so as to change the distance of the rail relative to the hoppers to move closer to a selected one of the two hoppers. The rail 34A includes a first mounting arrangement 33 at one end which carries the end of the conveyor frame. The mounting arrangement 33 allows up 30 and down pivotal movement of the conveyor frame 21 by a hanger 31 so as to allow the second end 21 B of the frame to raise and lower to the ground. The mounting arrangement 33 includes an upright pin 33A on the hanger 31 to allow 5 pivotal movement of the frame about a generally upright axis defined by the pin 33A. A second attachment arrangement 35 attaches the second end 21 B of the frame at or adjacent a second side 10B of the transport vehicle at a position 5 between the two hoppers. The straps 34C and 35D have couplings to allow the whole system to be removed. The attachment 35 includes a latch 38 to allow the second end to be held up between the hoppers in the transport position and to be released to be lowered in the operating position. In the transport position the conveyor frame 21 extends across the vehicle 10 and is carried by the mounting arrangement 34 and the attachment assembly in a position between the two hoppers extending across the vehicle. In the first operating position shown in Figure 6 the frame pivots so that the feed receptacle 29 is located underneath a first one 13 of the bottom discharge openings and in a second operating position the frame 21 pivots so that the feed 15 receptacle 29 is located underneath a second one 14 of the bottom discharge openings. In the operating positions the conveyor runs as drive by a motor 26A on the roller 26 in a direction so that it lifts the material from the selected discharge opening 13, 14 upwardly from the receptacle 29 to the mounting point 33 at the 20 first side 1 CA for discharge through discharge 28 to the side of the vehicle. In the transport position the frame 21 is horizontal and extends to a height no lower than the bottom of the discharge hoppers 13, 14 in the transport position. The second end 21 B of the frame 21 may include a ground wheel for rolling in an arc around the generally upright axis defined by the pin 33. A handle 40 25 defined by two arms 40A, 40B and a cross member 40C is provided at the first end 21A of the frame and is retractable into a receptacle 40D along the sides of the frame 21. In the extended position the handle allows the frame 21 to be manually tilted up and down about the mounting arrangement 33 to raise and lower the second end 21 B. 30 The second end 21 B of the frame when released from the latch 38 is lifted manually back to close the latch 38 and there is provided a spring assist defined by a spring arrangement 41 connected between the hanger 31 and a cross 6 member 23A of the frame 21 for providing an assisting lifting force lifting the second end 21 B of the frame to assist the manual effort required for lifting. In the operating position, the conveyor is arranged so that the discharge 28 is located at the first side 10A underneath the mounting arrangement 33 so as to 5 discharge at the side 10A of the vehicle with no extension portion into a feed hopper 50 of a conveyor. The conveyor arrangement therefore is carried on the vehicle in a convenient manner between the two hoppers without projecting outwardly beyond the sides 1 CA and 1 OB and without depending below the bottom of the hoppers 11 10 and 12. The single conveyor can then be deployed by lowering the second end to the ground and by swiveling the conveyor to one side or the other to take up her position where the hopper 29 underlies the hopper bottom of a selected one of the transport containers on the vehicle. In most hopper bottom vehicles of this type the geometry is conveniently arranged so that the swiveling of the conveyor to the 15 diagonal operating position causes the hopper 29 to move so that it underlies the hopper bottom 13, 14 which is half way across the vehicle. However in some cases where the spacing between the hopper bottoms 13, 14 is different, it is necessary to slide the mounting 33 along the vehicle by moving the rail on the straps 34C, 34D toward one of the hoppers. In this way the same conveyor 20 arrangement can be used for vehicles of different dimensions of spacing between the hoppers. 7
