A TANK CONSTRUCTION IN A BUIK C~RGO TRANSPORTATION SYSTEM
CONSISTING OF A LORRY AND TRAILER
The object of the invention is `a tank construction in a bulk 5 cargo transportation system consisting of a lorry and trailer, in which revolving cylindrical tanks equipped with parallel interior spirals are supported longitudinally on the chassis of the lorry and trailer, the tanks includin~ oppocite cones with opanings, the f irst cone being longer having a greater _ lO reduction when compared to the other, and in which system the tanks are arranged to b~ placed one after the other by pushing the long cone of the first tank into the larger opening of the second tank in ~hich case by rotating the tanks the mass of the cargo moves from the f irst tank to the second one.
For simplicity and clarity a bul~ cargo of concrete and its handling is referred to in this application, but the tank construction and method in accordance with the invention can equally well be applied to the transportation, mixing, 20 preparation and storage of other kinds o~ bul~ cargoes. other bulk cargoes of this kind can be, for example, liquid bulk cargoes, grain, fertilizer, feedstuffs, sand, crushed rock, salt, and cement. Here the cone and end of the cone forming part of the tan~ refers more prerisely to truncated cones, in 25 which the point of truncation generally forms the opening of the tank. The forms of the e~ds of the cones may also deviate from an exactly geometrical conical surface.
Nowadays concrete is mainly made in separate concrete sta-30 ~ions, ~rom which it is tran~ported ready-made by road to tha point of use. At the point o~ use the concrete is either transferred directly to the casting place or else to a suitable storage silo, from which it is used gradually.
35 One problem with the present system is that only relatively s~all amounts of concrete can be brought by road, lorries cannot be used for the longer term storage of ready-mixed or dry concrete, because on account of their cost they must be ~0,0/0~,0~ n./n~n~ ! ' continuously in use and when using the present storage facilities at working sites the more varied handling and preparation of bulk concrete is not possible.
5 ~ank car systems applicable to railway use., in which rotatable tanks are connected to one another longitudinally, are ~own from patent publications US 3,567,190, CH 497,961, and EP
240594. In these each tank has a pointed funnel at one end, which is pushed into the next tan~ through a larger opening.
10 When each tank is rotated, the bulk cargo is pushed into the next tank by an internal spiral, provided the direction of rotation is correct. Tn road vehicle use, particularly in concrete distribution, systems of this kind are of very little use. In particular the tank on the lorry cannot be filled and 15 emptied by means of the through-flow system, because there is no empty space in front of the tank for the opening. Tanks must be able to be filled by other principles than the a~orementioned through-flow principle. In general, in road vehicle use considerably more varied use is demanded than is 20 possible with the tank systems presented in the a~orementioned publications.
The intention of the invention is to remove the aforementioned problems and to show a new tank construction that permits 25 varied methods of handling the bulk cargo, it is easily emptied and filled and in this way is very well suited to the temporary storage and preparation of bulk concr~te.
The characteristic features of the invention are referred to 30 in the Patent Claims, The tank construction to be situated on the lorry or trailer includes a cylindrical rotatable tank with a horizontal axis.
One end of the tank has a conical ~orm on the end o~ which is 35 a ~illing/emptying opening, ~he tank being essentially additionally equipped with an internal spiral that extends ~rom end to ~nd o~ the tank to mix the mass within and to empty and ~ill the tank. In accordance with ~he invention, the WO90/08021 DCT!F'n0~00~14 ., ~
filling/emptying openi~g in the conical snd includes a pipe~
like interchangeable point, advantageously made as a conical cover, the broader end of which is dimensioned such that it fits the conical end the narrower end of the interchangeable 5 point being essentially smaller than the filling/emptying opening.
Advantageously the trailer tank is arrangled as a through-flow tank in such a way that there are co~ical ends at both ends of l0 it, which act as filling and emptying open:ings always depending on the direction of rotation, because as the tank rotates the spiral running round the inside mixes the mass in the tank and directs the mass to one or other end of the tanX, depending on the direction of rotation of the tank.
Advantageously an interchangeable point in accordance with the invention includes suitable locking elements and the conical end includes counter-elements, in which case the interchangeable poin~ can be lockQd to the conical end in 20 order to rotate with the tank structure. Suitable bolts, hinges, hooks, or other locking devices may be used as locking elements and counter elements. What is essential is that the interchangeable point is made to remain in place as an extension of the ~illing/emptying opening when the tank 25 revolves and the mass flows through the interohangeable points. Inside the interchangeable points a spiral cDn~truc~ion is arranged to corr~spond to ~nat in the tank, in which case when the tank is being emptied liquid can also flow efficiently out o~ the opening of the interchangeable 30 points.
In one adaptation o~ the invention, a ~ointed ~unnel component is arranged at at least one end of the tank structure for : ~illing the tank when the interchangeable point is not in 35 place. On the other hand, the funnel component acts ~s a shut-o~ element, ag inst which the concrete mass for example, can be mixed.
w o sn/nsn2l P ~ /Flsn/oon 4 .~ _ ~ a~q A suitable cover, by means of which the filling/emptying opening of the conical end ~a~ be absolutely tightly olosed, can also be used as a shut-off element.
5 Because the chassis of the lorry and trail~r have suspension, it is advantageous if there are locating elements ~etween them to keep the opposiny oonical ends at the same height.
An advantage of the invention when compared with known tech-10 niques is that it makes it possible to handle the bulk cargoin various ways. By means of the tank construction large amounts of bulk cargo can be transported, it is easy to use, to ~ill, and to empty, it can be used as a temporary store for various kinds of bulX cargo and it is easy to use in 15 restricted spaces such as building sites, mines, and similar places.
In what follows the invention is explained in d~tail by . referring to the accompanying illustrations, in which one 20 tank structuxe in accordancs with the invention is shown.
.
Figure 1 shows a tank trailer and the rear end o~ the lorry Figure 2 shows a tra ler and the use of its tank when trans~erring a hulk cargo Figure 3 shows a trailer tank seen 25 ~rom in front The Iirst tanK s~ructure is formed by a cylindrical tank 3 which is supported by bearings and is able to rotate on top of the chassis 2 of a trailer 1, both ends 4, 5 of which tank 30 have conical ends 6, 7 and a flange 8 that surrounds the filling/emptying openings at their points. Spiral 9 runs ~rom end to end inside ~he tank.
An interchangeable point lO consisting of a conical cover is 35 attached by means of a locking ~lement ll to the flange 8 of the conical end 6 of the other end 4 of the tank. A spiral 18 is arranged inside the in~erchangeable point 10 as a corrosponding continuation of spiral 9. Interchangeable point WO ~0/~8~ n!

lO can also be alternatively attached to flange 8 of the conical end 7 of the other end 5 of the tank strueture~ This is, however, an unusual method of use. It is much more usual to have to attach the i~terchangeable point 10 to the 5 correspo~ding conical end 15 of the lorry, which is explained later in greater detail.
In the case shown in the drawing the rear end 3 of the tan~ is closed with the filling funnel 12, which i,~ supported by an arm 10 resting on the articulated chassis 2 and is operated by means o~ a hydraulic cylinder 13. The illing funnel 12 includes a rubber gasket that presses against flange 8, and permits their mutual rotation.
15 When end 5 is closed by the filling ~unnel 12 tank 3 can be rotated in such a way that the mass inside it presses against the filling ~unnel 12 and thus the mass can be mixed, thus possibly preventing it from hardening too soon. When it is wished to remove the mass from the tank the direction of 20 rotation is revsrsed, when the mass discharges through the interchangeable point 10 or by raising the ~illing ~unnel 12, when the mass is made.to discharge into the lower ~unnel 14, to which a channel can be attached to direc~ the mass.
25 The conical end 15 of the tank 19 of lorry 16 also has available a lower ~unnel 14 and ~illing funnel 12 as well as its operating cylind~r 13, the manner o~ use of which is the same as in trailer lo 30 The ~ront of the cha6sis of trailex 1 includes a pin 23, which ~orms, together with ~he guide collar 24 situated at the rear o~ the chassis o~ ~he lorry 16, locating elements to keep the conical ends 6 and 15 on the same llne. The penetrating interchangeable point lO o~ the conical end 15 then rotates 35 c~ntrally. This situation is 6hown in Figure 2. Here the filling . funnel 12 is first rai3ed, after which the lorry 16 can reserve to connect with the trailer 1. In thi~ way the O!n80. 1 ~fr~ /n~

lorry 16 can fetch concrete from the trailer 1, whi h cannot be driven right up to the building site.
Interchangeable point 10 includes a rubher flange gasket 22, 5 which during the transfer operation is pressed against flange 17 o~ the conical end 15. This prevents completely any leak of the concrete mass. Usually the mass does not try to leak, if both tanks are rota~ed.
10 It is extremely important that the interior spirals 9 of the _ tanks 3 and 9 extend up to the flanges 8, even though they are reduced in height at the ends, and that the interchangeable point 10 also includes a spiral 18. By means of this, liquids, especially tank washing water are emptied completely.
It is often advantageous at work sites i~ trailer 1 can be left at the building site as a temporary store. The inter-changeable point 10 must then be turned and attached to the tank 19 of the lorry 16, by means of which tank 3 of trailer 1 20 can be ~illed. By using existlng e~uipment tank 19 of the lorry 16 can be emptied into tank 3 in only 6 minutes, which allows great efficiency in the trips of the lorry 1.
