Description

Description :

The invention relates to a container for transporting, for dosing and emptying granular and powdery material, with a container part, the opposite one End faces are arranged parallel to each other, a mat or a tape running in the longitudinal direction is flexible and preferably stiff in the transverse direction and one end of which by means of fastening elements in the upper Part of the container is attached to the wall between the end faces, and a gate in the upper part of the container for filling and emptying the material.

Such a container is mainly for transporting and storing granular and powdery)! material suitable and it is easy to empty and dose material from such a container. In general the container includes a container part, the opposite end surfaces of which are parallel to each other, a mat or a tape that fits between the sides of the container, one end of this mat or tape by means of a suitable fastening element in the upper part of the container is attached to the wall, as well as a gate in the upper part of the Container for emptying and filling the material.

Several device systems for transporting and storing granular and powdery material are known from the prior art. These usually contain a cylindrical or cubic container _of rigid construction and are in most cases made of steel. The granular or powdery material is filled into the container from above and is usually emptied from the container through an opening in the bottom. Since many granular and powdery materials form lumps due to moisture and heat, such containers often have special

elements to facilitate emptying. This is how the German published patent application describes 2 351 425 a container that is used to empty the container is provided with inflatable foils inside the container. On the other hand, in the DF-OS 1 9 ^ 3 9 ^ 0 an embodiment described in which the shape of the container wall by mechanical means of a cylindrical Shape is changed to a conical shape.

When the granular and powdery material is to be reloaded from a container, for example on a railroad car stands and through the ground on a road transport vehicle, such as on the back of a truck or a tractor trailer is emptied, but a separate device is always required if the container is permanently installed is a conveyor, like a conveyor belt or a screw conveyor system is required to transport the material from the discharge opening to the loading area. If the container is moved out of position to facilitate loading, this can either be done in sideways or in a vertical direction. To move the container sideways over the loading platform to push, whereby the material can be unloaded directly at the desired place, is both an auxiliary bridge over the platform as well as a drive device for moving the container is required. On the other hand is a special lifting device, for example a hydraulic one, for moving the container in the vertical direction Lifting device required. By lifting the container in the vertical direction it is achieved that a chute can be arranged between the emptying opening and the loading area, along which the granulate or powdery material can slide down to the desired place. As a result of this help and additional

direction are all device solutions of the containers, which are emptied through the bottom, quite expensive and complicated.

On the other hand, device systems are known in which the material is emptied through the upper end of the container. In these cases, the entire container is tilted or partially turned inside out. In this way, the charge can be discharged directly to the desired location, but at the same time, it is considerably more difficult to dose the material zn, as the containers, which are emptied through the bottom. As a result of the weight of the container, which is often quite high, the tilting device used is also quite expensive.

The aim of the present invention is to eliminate the drawbacks of the prior art and do one completely New container for transporting, emptying and dosing slightly clumping granules and powders Material to deliver.

The invention is based on the idea that the material in the container at the bottom and on two opposite sides is enclosed by a flexible mat or tape. When the mat is lifted out of the container, it will Material in the container is transported lengthways with the mat; and it can be easily emptied through the upper part. It It is important that the mat is constantly pressed tightly against the other two sides, whereby a penetration of the material between the edges of the mat .. and these sides prevented will.

This goal is achieved by having a mat between the end faces of a relatively narrow container, the width of the mat being substantially the same

is like the distance between the end faces of the container / and wherein the mat is flexible in the longitudinal direction and stiff in the transverse direction at the same time. One end of the mat is on attached to a roller which is mounted in the upper part of the container between the end faces of the container and which is rotated by a drive device. The other end the mat is in the upper part of the container on the opposite side by means of a suitable fastening element attached to the wall of the container. In a preferred embodiment, such a fastening element consists of a second role. The mat is covered with a material or with a layer that increases friction. When the container with granules or powder)! Material is filled the mat is pressed against the side and bottom walls of the container by the weight of the material. By turning the The granular or powdery material is rolled by means of the drive device due to the friction between the mat and the material is transported together with the mat in the upper part of the container, from where it is, for example, over a chute can be led out of the container.

The container according to the invention is characterized by the characterizing part of claim 1.

The device is suitable for fertilizer mass, grain, talc, etc. as well as unpleasant, granular and powdery Materials.

Considerable advantages are obtained from the invention. The device according to the invention is simple and can be used in in practice by using inexpensive equipment elements. The device can at the can be used for a wide variety of purposes; its construction is very good, for example, for dosing suitable for fertilizers directly on the field. According to the principle of the operation of the container can the material in the container does not clump, but is automatically

Automatically mixed when the material is emptied from the container will. The cleaning requirements of the container are 'fiTi'np ;, wo.il when using the mat automatically the Gloitflflehen cleanses on the end faces of the container.

Tn the preferred embodiment of the invention, in the beid · - are ¹ Find the mat attached to rollers, the material may be on both sides of the container, if desired even be ΕζΊ eiohzeitig, emptied. Mixing the material in the container is even more effective in this case. In this embodiment it is also possible to ensure that the container is completely emptied. It is possible to remove the last amount of material remaining in the container by converting the unit consisting of the rollers and the mat to a conveyor belt device by reversing the direction of rotation of one of the rollers, for example by releasing this roller from the drive device.

An embodiment of the invention is described below under Reference to the drawings explained in more detail.

Show it:

Figure 1 is a section through a container according to the invention,

Figure 2 is a side view of the container of Figure 1,

Figure 3 is an enlarged and more detailed view of the End of the roller, the drive device, the link mechanism and the locking devices in between, for the container shown in Figure 1,

Figure k shows a section through a second preferred embodiment of the container according to the invention.

The construction of the container shown in Figure 1 is as follows: The container part consists of parallel flat walls 1 and 1 ', end surfaces 15 and a bottom 2. Between the end surface 15 and the opposite end surface 15, a roller 3 is mounted in the upper part of the container. The end <4 of the roller is connected to the drive device 6 via a suitable mechanism. The drive device 6 can be a hydraulic cylinder, a hydraulic motor or a corresponding motor. The end H of the roller is also provided with a suitable locking device 7, with which it can be ensured that the roller only rotates in the desired direction. A flexible mat 8, which is both stiff and resistant in the transverse direction, is attached to the roller 3, this mat being covered with a layer to increase friction. The other end of the mat 8 is connected to the opposite wall I ¹ via a fastening element 9. In this embodiment, the fastening element 9 can consist, for example, of a metal bracket fastened to the wall. In the container on the roll 3 there is a gate 10 which is opened upwards in order to fill in and empty the material. A plate 11 with the same width as the wall is mounted on the bottom part of the gate 10, the plate being aligned diagonally upwards against the roller 3 and at the end of which a scraping edge 12 is provided, which can be designed, for example, similar to a rubber strip or brush and which is pressed diagonally from below against the roller.

In an exemplary embodiment, a container, as described above, with a volume of approximately 5 τη made from plywood panels reinforced by a suitable steel frame. The length of the container was 2.5 m, the width 1.2 m and the height from the floor to the top

Point of the roll 2 m. A linen-reinforced rubber mat with a thickness of 5 mm was used as the mat. the End walls were covered with a layer of rubber around the Improve seal between the mat and the walls. A hydraulic cylinder was used as the drive device was used and a ratchet was used to connect the hydraulic cylinder to the end of the roller.

The container works as follows: When the container is empty, the entire length of the mat 8, except for the remaining part between the roller 3 and the fastening element 9 _{S, is} advantageously completely wound onto the roller 3. When the container is filled with a granular or powdery material, such as fertilizer mass, the roller 3 is released from the drive device 6 and the locking device 7, the mat B being unwound from the roller 3 and by the weight of the material to be filled against the Floor 2 and walls 1 and 1 'is pressed. As a result of the construction of the mat 8 _S which is rigid in the transverse direction, no material can fall between the edges of the mat 8 and the end surfaces 15 on the floor 2. When the amount of material to be filled in reaches the height of the roller 3, the filling process is stopped and the locking system 7 on the roller 3 is switched on.

When material is to be emptied from the container, the drive device 6 with the roller. 3 connected, the gate 10 is opened and the mat 8 is wound onto the roll 3 by the drive device 6. With that, the material follows the mat on the roll 3, from where it is over the plate 11 and by means of a possibly additional slide to the desired Place can be guided. The scraping edge 12 removes any possibly adhering to the mat 3 Material from the mat. When metering in this way, any desired amount of granular or powdered Material must be emptied from the container. When the

total length of the mat 8 except for the part '/, wiping the roll 3 and the fastening element 9 is wound onto the roll, even the last remaining material can be removed from the Container and can be removed from the mat when the fastening element 9 is at a higher point than the roller 3. is arranged with the mat 8 in the inclined position with respect to the horizontal. The sliding down of the material from the mat 8 can by coating this part of the mat 8 with a suitable Film, for example PVC or a corresponding slippery plastic film are promoted.

Figure k shows an alternative preferred embodiment of the container according to the invention.

The construction of the container part is essentially similar to the embodiment described above, the fastening element but now consists of a second roller 9, which is similar to the first roller 3 and parallel to it is classified. The second roller 9 is installed in a manner corresponding to the first roller 3 and preferably on the same Height arranged with this. A gate 13 corresponding to the gate 10 is located on the roller 9. The second roller 9 may be provided with a separate drive device, or the same drive device can be used to rotate it as well as used to rotate the first roller 3. The distance between the rollers is preferably about here equal to their length, that is to say the opening through the opposite end faces 15 and the one between them Low rollers 3 and 9 is formed, has a substantially square shape.

A stiffening element 1.4, in the present case a metal rod, is located between the end surfaces 15 to reinforce the container structure.

The operation of the embodiment shown in Figure H is largely similar to the operation of the preceding

- / ir.

gone execution form, with reference to the Figures 1 to 3 has been described. At the beginning, however, before filling, the mat R is placed on rollers 3 and 9 wound so that there is an equal length of mat on both rollers. The filling and emptying of the container takes place in a way that corresponds to the one described above, but the material can now always pass through turning the roller on the relevant side can be emptied on each of the two sides of the container. If the second roller 9 has its own drive device, the emptying of the container on both sides can be done simultaneously respectively.

After almost all of the material in the container has been emptied and the entire length of the mat except for the portion remaining between the rollers 3 and 9, it has been wound onto the rollers 3 and 9 (This horizontal position is shown with dotted lines), even the remaining material can be removed from the container be unloaded by releasing one of the rollers from its drive and the lock and releasing the other roller is allowed to rotate by means of the drive, so that a conveyor belt is obtained, with the help of which the material on one side of the container can be conveyed. In such a case, the mat must be so long that at least one the distance between the rollers 3 and 9 corresponding length is wound onto one of the rollers at any time.

In operation, the stiffening elements mentioned above were used l4j arranged between the end faces 15 found that it can be ensured that the end faces of the container are not affected by the weight of the material to be loaded must be pushed outwards. Such bulges can namely have the consequence that the edges of the mat 8 are no longer defined tightly pressed against the end surfaces 15, so that in this case Material can fall between the walls and the edges of the mat. By using such stiffening elements it is possible to achieve the required seal while reducing the material thickness the walls and end faces can be kept relatively small. In this embodiment, similar to the previous one, it is advantageous to coat the surfaces of the end faces with a suitable layer of a friction-increasing material To cover material.

In an exemplary form, a container according to the invention was produced, the dimensions of which were the same as those of the previous example. The second roller (diameter 1h cm) was arranged at the same height as the first roller, so that the distance between them was equal to their length, ie 1.2 m.

Finally, it should be noted that the edges of the tape can be provided with known sealants, to keep the edges in constant contact with the end face walls of the container during operation. Such means can be elastic, filled with a gas such as compressed air or a non-freezing liquid such as pressure oil Be hoses.
