Mobile allocation device for concrete additives and

Concrete binder

The invention relates to a device for loading a collecting container with granular substances, in particular with additives for the preparation of concrete, in which an open Scaffolding above one provided with closable outlet openings Base plate to support above the collecting container Star-shaped, radially directed walls to demarcate separate ground-level storage facilities is provided.

The formation of the feeder frame from vertical, formed by profile iron pairs of supports is known individual profile iron in pairs have such a gap that the planks forming the storage walls between them up to a vertical. Axis above the base plate, in which they meet in a star shape, can be pushed through »The present invention aims at an advantageous one Perfection of this device especially for the change of its place of use.

There were already mobile distributors with measuring containers and Scales for loading concrete mixers with measured Quantities of aggregates and binders in different Embodiments proposed. An embodiment has also become known in which a so-called scraper weighing silo Is used. The aggregates are filled into the silo by means of a hand scraper weighed and transferred from it to the elevator bucket of the concrete mixer. Wheels are used to transport this feeder are detachably mounted on a frame which has a part which can be folded down into the working position and which together with another part, which is mounted vertically on the frame, forms a slideway for the silo on which the silo runs its transport position can be converted into the working position in which he operates a scale · However, this attendant does not have an allocator and is therefore only for processing a single grain component or suitable for mixed gravel.

Furthermore, a mobile dispenser was proposed which the lowest part of the Measuring container to increase the ground clearance of the mobile Removable unit and the guide pulley for a scraper rope for loading the additional material bags with the hand scraper shovel is arranged on a fork-like drawbar which can be folded down to reduce the driving profile height. This distributor is for several aggregate grain sizes suitable, but must be loaded with a hand scraper.

Finally, an arbiter has become known, the one Collecting container, a scale and an open frame to support the star-shaped arranged above the measuring container, having radially directed walls to delimit a number of separate, ground-level Yorratslager. the The supports that form the open framework are provided with horizontally-positioned closable outlet openings above one Arranged base plate, and the end frame connecting the upper ends of the supports carries a feeder, for example a scraper winch or a boom scraper device.

The disadvantage is that in lalle one implementation of this Dispatcher from one job site to another ^, time consuming and costly dismantling work on the old one, as well as assembly work The new construction site requires »For this, the scaffolding usually has to be dismantled, definitely however, the feeder can be dismantled and reassembled

This resulted in the object on which the invention is based, which consisted of the last described allocator in such a way to train mobile that at the point of use the full height of the dispenser for storage of the aggregates is available stands without the fact that the feeder remains on the feeder during the transport according to the road traffic approval regulations maximum permissible vertical profile is exceeded, and that the volume of the collecting container for the aggregates, which forms part of a scale in a manner known per se, is variable.

This object was achieved according to the invention daduroli that the Supports formed from profile iron pairs that form the open framework of the known distributor, are divided in a horizontal plane, and their upper part telescopically in the lower parts can be inserted. Furthermore is the base plate with the Alis barrel openings on a removable Chassis provided frame arranged, which at the same time the weighing linkage with a removable and for transport Carries interchangeable collecting container for the additives for different contents. This ensures that the inventive The direction of the door, even with the tipper installed, is significantly below the permitted maximum height for road traffic, thus a considerable additional degree of truthfulness offers that also the structure of the dispenser at the point of use with the simplest means and in the shortest possible time Time can be accomplished, and that finally the container forming the weighing vessel for the additives does not have to be larger than the capacity of the concrete mixer it requires that the pit for the elevator bucket of the concrete mixer, which drives under the collecting container, does not need to be created unnecessarily deep and with correspondingly unnecessary effort. It is particularly advantageous that despite the above-ground arrangement of the collecting container and despite the portability of the device according to the invention within the limits set by the road traffic licensing regulations, due to the telescopic Extendability of the supports for the box partitions, in the The dispenser kept the same stock in the additives boxes can be, as with the underground arrangement of the

Collecting container. Another advantage is that the Slicer for the dispenser, for example a hand scraper winch or a cantilever scraper device known per se his winches can be left on the allocation device during transport, so not with the otherwise for it required effort dismantled before transport and attached to the must be put back on at the new place of use.

An exemplary embodiment according to the invention is presented below Hand of the drawing besehrieben and explained in more detail. Show it

Iron pairs formed at their lower ends advantageously by gusset plates 9 reinforced supports 12, 13 for the partition walls 10 of the various aggregate stores are "divided at 11, so that their upper parts 12, as shown in Pig may be. In the extended position they are connected to each other by screws 14 or by similar means. A on the upper end frame 15 of the supports 12, 13 arranged Besohl cker 16 (I ¹ Ig.2) can also remain during transport to the metering device 7 It is only fixed in a horizontal or approximately horizontal position when, as in the embodiment shown, can be pivoted about the axis 16 *, by a holder 1?

The frame 1 also carries a hinged linkage 18, 18 ', 19 with a suspension frame 21, to which the collecting container 20 is flanged to be exchangeable at 20 *. The part 22 of the binding agent chute located firmly on the collecting container 20 can be moved in the vertical direction by the bellows sleeve 23 and is easily detachably connected to the part 22 'of the chute attached to the frame 1. The volume of the catch container 20 ^u for the aggregates can always be adapted to the volume of the concrete mixer, not shown, by simply replacing the container, so that in many cases the digging of a pit can be omitted or at least only for the elevator bucket of the concrete mixer itself is required. Interchangeable supports 24, 2ξ> of different lengths, which can be arranged as feet under the frame 1, also improve the

adaptability of the allocation device to the respective Requirements of the construction site.

To reach the transport position (Mg.2, 3), the upper support parts 12 are retracted into the lower support parts 13, the feeder 16 is locked by means of the bracket, the collecting container 20 and the frame supports 24, 25 are removed, the G-abel chassis 2, 3, 4 inserted into the paralyze and screwed his wheel arch 3 to him. Conversely, to set up the dispensing device at the new location, the chassis 2, 3, 4 is removed and the frame 1 is placed on the frame extensions 24, 25 required in each case. Then the weighing vessel 20, which was removed for transport, is flanged to the hanging frame 21: the balance 18. The part - 22 of the binding agent chute is connected by the bellows sleeve 23 to the part 22 ^t of the chute which is fixed to the base plate 5. The supports 12, 13 of the distributor 7 are moved from their transport position (FIG. 2) into the working position. 1 extended and connected to each other in this position. The bevelled sides 1 ^{f of} the frame 1 are covered with planks 8 and the planks of the partition walls 10 are inserted vertically one above the other between the supports 12, 13 to form the storage spaces located in sectors around the allocator.
