The invention relates to a container scale for receiving and weighing controlled by the scale a batch consisting of two or more components, especially for the aggregates of Concrete. The purpose of the invention is to train such a balance in such a way that it is at low Overall height enables an even faster and more complete emptying than with the previous ones known scales is the case.

In the case of the well-known container scales used, the discharge base has the one required for emptying Tilt. As a result, these scales have a relatively large overall height. this in turn has the consequence that systems or facilities in which such scales are used, likewise must have a large overall height or be provided with a pit. Particularly unfavorable This creates conditions in the case of dosing systems arranged at ground level, especially for the aggregates of concrete. In these systems, it is necessary to accommodate a container scale known designs to provide a deep pit, otherwise a considerable amount of dead material to be purchased must be taken.

In a known method for the continuous weighing of bulk material and a device for Carrying out the method, the bulk material is intermittently connected to a scale Turntable supplied and again at another point on the plate during the time of supply discharged. The scales are only released for weighing after the volumetric feeding. The feed the good is therefore not controlled. It is also known per se in continuous scales, the Always support the scale container on the scale.

The object of the invention is now to design a container scale in such a way that once their The overall height is so low that neither a pit to set up the scales is necessary, nor an uneconomical one There is a dead stock of material, but on the other hand a fast filling and Weighing as well as a quick and complete emptying of the scales can be achieved.

The object is achieved in that, according to the invention, the base of the container consisting of an upper, ring-shaped jacket and a separate, spaced-apart circular base is provided in a known manner with a vertical and supported on the scales rotatable support body is firmly connected, while the jacket is attached to the arms protruding from the support body to the container scale controlled by the scale
Pick up and weigh one of two or
multiple components batch,

is, and that the space between the jacket and the floor, on the outer periphery of the floor, with the scales non-rotatably connected intermediate jacket to the outside. For emptying the balance container is advantageous a pivotable into the space between the upper jacket and the bottom of the container Emptying flap provided. To drive the support body is expedient in the interior of the a motor arranged in a hollow cylinder existing support body. The intermediate jacket is by means of Arms must be firmly connected to a cover plate of the balance. Furthermore, the arrangement can be made in this way be that the evacuation flap forming part of the intermediate jacket is connected to the former by means of a Hinge joint is hinged. The upper jacket expediently tapers conically downwards, whereby its the lower edge has a smaller diameter than the bottom.

By dividing the scale container into two rotating parts, namely one for filling in the goods to be weighed and one below this upper part at a distance Bottom, on the one hand, when the goods to be weighed are poured in, it is evenly distributed within of the entire scale container achieved, on the other hand, a simple and reliable emptying on the Preserved the scope of the container. These features, in turn, make it possible to use the scale container perform the desired and advantageous low overall height for many applications and from to be loaded from any point.

The invention is explained below with reference to the drawings using an exemplary embodiment. In the drawings represents

F i g. 1 shows a vertical section through the container scale along line II of FIG. 2,

F i g. 2 is a plan view of FIG. 1.

The container scales basically consist of a subdivided container. This thus has an annular shape Upper container part 1 and a container base 2. The upper part of the container 1 forms a low one Cone which tapers conically downwards, so that the lower edge of the upper part 1 is smaller Has a diameter than the container bottom 2, which is designed as a flat circular disc. Of the The container base 2 is arranged at a distance below the container upper part 1. Both the container top 1 and the container base 2 are firmly connected to a central hollow cylinder 3, and although the upper container part 1 on the arms 4, while the lower container part 2 directly with the Jacket of the hollow cylinder 3 is firmly connected. The arrangement is now such that the hollow cylinder 3 can rotate with the upper container part 1 and the lower container part 2. To that end is the hollow cylinder 3 is mounted on the slewing ring 5, which in turn is on the cover plate 6 of the weighing device is attached. Inside the hollow cylinder 3 is the drive for the rotary movement of the container 1, 2 housed. This drive essentially consists of the motor 7 and the countershaft 8. The outer circumference of the container bottom 2 is surrounded by a fixed boundary jacket 9, which is firmly connected to the scale plate 6 by means of the arms 10. A part 11 of the boundary jacket 9 is designed to be foldable and for this purpose by means of a hinge 12 on the fixed part of the boundary jacket 9 hinged horizontally pivotable. This flap 11 is slightly lower than that Distance between the lower edge of the upper container part 1 and the container bottom 2. Can be folded in at this Place of the boundary jacket 9, the outlet 13 is provided for the weighed goods. the Weighing device itself is designed in a known manner and consists essentially of the levers 14, which in turn rest on the support frame 15. At 16 the circular pointer head of the balance is indicated.

The container scale works in the following way: The bulk goods to be weighed can be placed anywhere of the scale container 1, 2 and passes through the container top 1 to the container bottom 2. When the scale container 1, 2 is rotated, it is thus over its entire circumference evenly loaded. Since the diameter of the lower edge of the upper container part 1 is smaller than that Diameter of the container bottom 2, is formed from the lower edge of the upper part 1 to the lower Bottom 2 to a natural angle of repose of the goods to be weighed. Through the fixed boundary jacket 9 it is avoided that easily rolling material falls over the outer edge of the container bottom 2. When the container has reached its predetermined filling weight, the hinged part will move swiveled inside to the hollow cylinder 3, whereby the goods to be weighed on the flap 11 along when further turning the container is emptied into the outlet 13. When the flap 11 is already swiveled in a little its further opening movement is brought about by the outflowing material itself, until the free end of the flap 11 comes to rest against the hollow cylinder 3. To this end, the Flap 11 is bent at its free end to form a contact surface 17.
