Bullet shovel
The ball shovel is a recording device with a spatially movable boom and a conveyor belt arranged in it. The continuously working device is suitable as a charger for bulk materials and as an extraction device for soils of lighter extraction classes.
Structure and mode of operation
The inventor is Adolf Rubin from Leipzig, who in 1943 applied for a patent for a “recording device with a spatially movable arm and a conveyor belt”. Ball shovels are continuously working chargers that run on caterpillars . They have a freely swiveling extension tube, at the end of which a rotatable, spherical extraction body picks up bulk material such as gravel, crushed stone or earth. The bulk material falls through the extraction body onto a conveyor belt in the cantilever tube, which then transports it to another conveyor belt. Well-known manufacturer of these spherical shovels was the company Adolf Bleichert & Co.
