Scraper loader for bundle storage locations

The invention relates to a scraper loader for round storage spaces at least one liftable and lowerable scraper, which is around a in the center of the Bundlagerplatsses standing vertical axis is pivotable and the bulk material one at the center of the Ruitilagerplatte arranged delivery point.

In addition to the depletion of bulk goods such as coal, ores, fertilizers and the like, from balances, in addition to excavators, grab cranes, Shovel loaders and other equipment scraper loaders in use. The scraper loaders have the advantage of a continuous working method among other things the advantages «that with the scraper boom large working area can be grasped, and that at the same time with the depletion also a mixture of different, in Layers of overlapping types of bulk material are made can. In addition, stuck stored goods can also be stored with scraper loaders can be solved and saved without difficulty.

It is already known, also for the internal storage of round storage locations, where the bulk goods are heaped up on a circular conveyor Bulk material dump is located next to bucket wheel excavators and other equipment to use scraper loaders, which are the focus of the Round storage location stationary, but pivotable about a vertical axis are set up, so that of the liftable and lowerable

Kratzaualeger the bulk material dump can be recorded on its "entire extent * Since with these scraper loaders the scraper loader however, so arranged is the “a transfer point immediately is above the funnel inlet of the central delivery point » result from storage spaces with larger diameters and correspondingly large storage volume, excessively large lengths of the scratch «· boom. This requires heavy, complex and extremely uneconomical scraper loader constructions.

The invention is primarily based on the object to parts to fix. The invention also aims to provide a scraper loader for round bearing points in structurally appropriate catfish in such a way * judge that it can also be used to store bulk goods.

According to the invention, the scratch loader »axis pivotable equipped with a to the vertical * 'with a chassis on a arranged at the foot of the inner slope of the bulk material stockpile ring rail continuously' supporting framework for dm Kratzaueleger, wherein between lying in the region of the landing gear delivery point of the scraper boom. ' and the central delivery point a conveyor belt that can be pivoted around the vertical axis with the support frame is provided.

Several Kratζausleger, preferably parallel to each other, be arranged. Around the bulk material dump not only on the inside slope, but also in the case of a trapezoidal dump cross cut at the top, it is therefore advisable to use a scraper arm, which is known per se wise consists of articulated boom parts, preferably each suspension part is on an adjustable lifting device, 2.B. to a pulley or the like. on* hung so that the two hingedly connected Aus * Leg parts can be swiveled either together or each for calibration in the vertical plane · It is suitable that the

Dieter only needs WaXX if there is a sharpener needs to be removed asu.

In a 2-week construction, the supporting structure, which can be pivoted about the central vertical axis, has a bulk material dump radially spanning cantilever on which the Kratzaualeger can be hung. According to a further feature of the invention an Elnepeicherband can be arranged on the supporting frame of the scraper boom, preferably the radial cantilever beam. is in the middle of the storage area. In this In the case, the support frame serves both for the storage of the scraper boom and for the storage of the binspeioherbandes as well as for the storage of the between the scraper boom and the delivery «· Place the conveyor belt switched on as an intermediate conveying means.
