larger tank both for road transport and the full and effective application of the grain from the Tank more difficult.

The object of the invention is to provide a grain tank for a To create a combine harvester that avoids or reduces the disadvantages mentioned.

In the case of a tank, in particular a grain tank intended for a combine harvester, this task is comprised of a bottom and opposite side and opposite end walls solved in that at least one of the walls is adjustable to change the capacity of the tank.

Preferably the opposite side walls are for changing the capacity and the outer ones Tank width can be moved relative to one another or away from one another.

In the bottom, a grain outlet can be provided which have at least one articulated bottom part and in a position can be pivoted in which the inner periphery of the tank in the direction of the outlet converges below.

The adjustable walls can be moved by hand and be secured with fastening means or they can be adjusted with the help of hydraulic pistons. aside from that For example, the outlet can be equipped with a grain conveyor screw between the end walls runs parallel to these. Incidentally, two can swiveling floor parts available no, each on are hinged to a point near the outlet and extend from the outlet to an end wall.

According to FIGS. 1 to 4, a combine harvester designated 1 has a grain tank 2 carried by ground wheels J on. The tank 2 is open at the top and consists of a bottom 4, two opposite side walls 5 and two opposite end walls 6. The side walls are equipped with end and base parts (flanges) 5A, 5B, which the end walls 6 and the bottom 4 slidably or in overlap in another way. The parts 5A, 5B on the right wall 5 (Fig. 4) cover the inside of the

- 4 -109827/1017

Tanke's, while parts 5A, 5B 'on the left of the Wall 5 (Fig. 4) overlap the outside of the tank.

In the bottom 4 a grain outlet 7 is provided in which a screw 8 is located, which feeds the grain through the outlet to an emptying pipe 9 shown in dashed lines. The opposite side walls are adjustable between a road transport position (FIG. 2) and an operating position (FIG. 3). In the road transport position the side walls 5 do not protrude beyond the wheels of the combine harvester, thereby driving through narrow streets and narrow passages as well as transport by rail or road vehicles is facilitated. During the The capacity of the tank 2 can be increased by pushing the side walls 5 apart. Such Sliding movement can be carried out by hand, with the walls held in place by bolts or you can use hydraulic pistons 10 (Fig. 1 to 4), which .übernehmen the displacement of the side walls.

To improve the flow of grain from the sides of the tank 2 to the outlet 7, at least one inclined partition 11 is provided and the bottom can, as shown in FIG. converge downwards. The screw 8 is from one Pipe 12 (Fig. 2 and 3) or from the bottom 4 (Fig. 1 and 4) surrounded and the drain pipe 9 is by means of an articulated connection Ij5 connected to the tank. The emptying pipe 9 contains an end emptying screw, not shown, via a bevel gear 14 from the Screw 8 is driven. The pipe 12 and the articulated connection IjJ are connected to only one side wall 5 and move with this. The drive of the screw 8 is attached to a drive shaft 15 at one end Disc 8a. Derived from the combine harvester drive. The screw threads 16 of the worm 8 are on the

.. 10.9B2 7/1 017

pulled (female) part of the shaft 15 provided during of the drive allows the worm 8 to move relative to the disk 14.

During operation, the grain is taken from a lower grain auger 22, an elevator 23 and a grain feed screw conveyed from the grain collector of the combine harvester into the tank, in which it is evenly conveyed by an auger 25 is spread.

To facilitate the displacement of the end and base parts 5A, 5B over the fixed side and base walls 4, linear bearings 26 are provided, which are designed as roller bearings (Fig. la) or sliding cushions 28 (Pig. Ib) can.

5 and 6 show modifications of the grain tank according to the invention, similar parts being denoted by the same reference numerals and the base consisting of two parts 16 articulated to one another in the vicinity of the outlet 7 at 17. Each part 16 runs essentially from the outlet 7 to a wall 6 of the tank and is provided with a segment-like wall 18 at its free end. Against these walls 18, elastic sealing strips 19, which are connected to the end walls 6 and prevent grains from ringing between the walls 18 and the walls 6, rest against. The parts 16 can be moved by hand or - as shown - by means of hydraulic pistons 20 which are movably supported in carriers 21. When the tank is filled with grain, the toi Ie 16 assume the position shown in Fig. 6, which causes the largest fanrjungß '/ errnögen the tank. During the emptying of the tank, the parts 16 are lifted into the i3 te.I lung n-ach Fig. 5, whereby the bottom 4 has a downwardly converging Go:; taIt. nnnimrnt, so that the grain -

Although the invention in connection with the grain tank a combine harvester has been described, it can also be used in connection with other tanks for discrete materials be used. In addition, a grain tank can be created that has two movable side walls as well as has a movable floor. In addition, it is possible to make only one side wall movable and to provide only one or more than two floor parts 16 on the floor.
