State of the art

There are devices for picking up soil material as well Devices for separating each known. The "excavators" used here - or "caterpillar" vehicles, however, do not form a technical unit the sieves for separating the soil material. So must the received good overall it must first be transported a longer distance and often temporarily stored before it can be separated into the desired fractions. As a result, the known devices are unsuitable for the large-scale processing and separation of soil material, e.g. from stony sandy beaches,

Object of the invention

The registration is based on the task of large-scale floor areas, such as e.g. sandy beaches of materials above a certain grain size, e.g. to clean or clear stones and the separated materials to be removed continuously without affecting the forward movement of the reamer. "

The clearing device must be usable on soft ground and on different pick-up and delivery heights of the conveyed material can be set.

The object is achieved according to the invention by what is specified in the claims Features solved.

Description of the invention

In Fig. 1 is a caterpillar vehicle (1) with a shovel-shaped pickup (2) and conveyor belts (3) and (4). The material picked up, e.g. earth, gravel sand or stony sand, is placed on a vibrating sieve (5), which the fine material E.g. sand lets through downwards, while the coarse material, e.g. stones, is diverted to the side via a chute (6). From the chute (6) the coarse material can move into mobile containers or unloaded onto trucks. To adjust to different The vibrating sieve (5) and above it the chute (6) are connected to a hydraulic cylinder (7). Likewise, the conveyor belt (4) can over Hydraulic cylinder (8) can be raised or lowered if this should be necessary when unloading the fine material.

In Fig. 2, the crawler vehicle (9) is with a paddle wheel-shaped. Pick-up (10), throw conveyor (11) and conveyor belt (12) are shown. Since the litter conveyor (11) consists of a fine-meshed net, this does not happen Back fine material below the caterpillar (9) on the ground. Only the coarse arrives at the conveyor belt (12) and from there into mobile containers or trucks. To adapt to different loading heights, 2 hydraulic cylinders (13.) and (14) intended.

During operation, the soil material can be removed in layers, whereby the digging depth can be adjusted depending on the strength of the soil. For this purpose, the bucket wheel pick-up (10) is lowered via the cylinder (15) and the oscillation amplitude of the throwing conveyor (11) is set accordingly.

The particular advantage lies in the continuous classification with extraction of reusable coarse material. So will. e.g. when cleaning a beach from Stones, gravel or floating debris, the fine sand is returned immediately, while the coarse fraction can be processed in the gravel or concrete plant .. Analogously there are also possible uses for river bed cleaning and its banks; Floors of dams, reservoirs and landfills; agricultural used areas.
