Storage containers for crops

The innovation relates to a storage container for harvested material made of sheet metal, a floor, two side walls and two Has end walls and is equipped with facilities for transport and for stacking.

The innovation is used in particular for the storage of harvested maize on farms and in warehouses.

For the storage of maize, which in the Federal Republic Germany is mainly used as animal feed, large quantities of storage containers with a volume are used of about 2 cubic meters are required, which can be stacked on top of each other for efficient use of the storage rooms must and which can be transported empty and filled without difficulty.

Storage containers for crops have long been known in a wide variety of designs. All of these storage containers however, they are designed with a lot of material and assembly and their stackability is very limited.

The task of the innovation consists in the design of a storage container that can be manufactured inexpensively and thereby has high stability as a prerequisite for excellent stackability.

To solve the problem, a storage container of the type described at the beginning has been assumed and the object was achieved in that the side walls run parallel to the floor, with their elevations outward-facing corrugations are supported by two "rows of slots running perpendicular to the floor." are traversed transversely, and the end walls on their long sides twice at right angles inwardly bent folds have, the edges of which sit in the slots. It has been shown by investigations that that the proposed design of the side and end walls in combination with their mutual Connection with the help of the edge strips and the slots an excellent stability and thus a high load capacity as a result, the production costs surprisingly low because of the very simple production are. The high load capacity results in very good stackability.

The edges of the slots are advantageously connected to the edge strips by weld seams. Through this Measure, the stability is significantly increased, so that - as could be determined - at least five full storage containers can be placed on top of each other without irreversible or impermissible deformations occur in the containers.

The beads expediently have a gable roof-shaped profile this makes it easier to manufacture them on the press brake.

The end walls are advantageously provided with a pyramid-shaped crown, which increases the resistance contributes to the end walls.

At the bottom of the storage container can be two U-shaped bent Feet attached and be arranged at the head of the side walls upwardly open gutters. The gutters serve to accommodate the feet, so that this constructive Ausgestal device in a very simple way the stacking one another permitted.

An L-profile serves as a channel.

For transporting the proposed storage container with HiI-fe A forklift truck can have two parallel U-rails attached to their backs on the underside of the floor be. If these U-rails have recesses on their legs, perpendicular to the pairs of L-profiles then it is possible to reach under the storage container with the forklift in the transverse direction.

The innovation is shown below in a preferred embodiment explained in more detail with reference to the accompanying drawing, showing: 25th

The proposed storage container consists essentially of a base 1, two side walls 2 and 3 and two End walls 4 and 5, which are made of thin sheet steel. The side wall 2, the bottom 4 and the other Side wall 3 are made of a common sheet metal blank by appropriate folding in the form of a U made.

The two side walls 2 and 3 each carry a plurality of beads 6, the elevations 7 of which have a gable roof-shaped profile exhibit. These beads 6 run parallel to the floor 1 or horizontally, and their elevations 7 point each to the outside, i.e. away from the inside of the container.

The beads 6 are in the area of their vertical edges in the transverse direction of two rows of slots 8 (see. Also Fig. 3) interspersed, which perpendicular to the ground or vertically get lost. The clear width of these slots 8 is slightly larger than the sheet thickness of the end walls 4, 5, and the slots 8 penetrate the beads 6 up to the top of the side walls 2 and 3.

Both side walls 2, 3 are bent over in a U-shape at their upper edge to form a downwardly open edge 10.

The two end walls 4 and 5 of the storage container according to the innovation are to increase their stability with a very low, pyramidal and outwardly directed / -teten Provide crown 9 · The end walls 4, 5 point

Ι Post-like folds on both of its vertical long sides 11, which are bent twice inwards at right angles (see. Fig. 2) and thus flat edge strips 12 wear, which are parallel to the inside of the end walls 4, 5.

The end walls 2, 3 and the end walls 4, 5 of the storage container are composed so that the edge strips 12 of the end walls 4, 5 sit in the slots 8 of the end walls 4, 5. To do this, the Edge strips 12 of each end wall in the vertical direction into the slots 8 of the two adjoining side walls 2 and 3 inserted. The edges 13 of the slots 8 are firmly connected to the edge strips 12 by welds 14, it is shown in Fig.l.

At the bottom 1 of the storage container, two feet 15 bent into a U-shape from steel tubes are attached, which slightly are so far obliquely outward that the central axes of the U-backs 16 lie in the plane of the end walls 4, 5. At the head of the side walls 4, 5 grooves 17 open towards the top are arranged, these grooves 17 consist of one steel L-profile, which is attached by welds 18 to the side walls 4, 5, the central axis of the U-back 16 and the sole of the channel 17 lie in the same vertical plane. Connect stiffening plates 19 the U-back 16 with the lower edges of the end walls 4, 5 or the bottom 1. The chosen arrangement of the Feet 15 and the channels 17 allow several storage containers to be stacked one on top of the other.

On the underside of the floor 1 with their back 20 two parallel U-rails 21 made of steel are attached, which to accommodate the fork of a to transport the storage »- holder serving forklift is provided. These
