Abstract: A continuous-conveyance bulk-cargo ship unloader. It has a pickup at the bottom of an upright screw conveyor. The screw conveyor rotates around a vertical axis and relays a more or less horizontally free-flowing stream of bulk material to a sandwiched-belt conveyor accommodated in an elephant trunk. The object of the present invention is to ensure that the sandwiched-belt conveyor will be supplied to capacity as effectively as possible and with as little friction as possible. The belts that comprise the sandwiched-belt conveyor (4 & 5) are curved at the bottom. The cylinder (10) that deflects the counterforce-application belt (9) is in approximately vertical alignment with the cylinder (12) that deflects the force-application belt (11). Both cylinders demarcate an intake-slot throat (13). The intake-slot throat intercepts the particles (8) of bulk material leaving the top of the screw conveyor (3) in a horizontal or upward-sloping trajectory. The screw conveyor (3) and its associated relay section (3e) are at an angle of 0.degree. to 15.degree. to the axis of the sandwiched-belt conveyor. The sandwiched-belt conveyor travels as rapidly or approximately as rapidly as the particles travel in their trajectory.

Abstract: The operative members in open pit mining apparatus, designed as strata cutting and loading machines are exposed to high wear and tear in practical operation. The cutter tools (3) are so designed that those picks (5) which are cutting are in their operating position while the picks (5) for the other working direction are swivelled out of the cutting orbit. They must be robust and always functional. Pick holders armed with picks (5) are therefore pivotally disposed on hinges on both sides in the direction of rotation on the cutter bars (1) arranged on the circumference of the cutting drum. Two pick holders on opposite sides, form a pair. These are interconnected in articulated manner by a bar of such length that one pick (5) can perform its winning action while the other pick (5) is angularly displaced out of the groove being cut. Due to the excavating resistance, the cutter tools (3a and 3b) automatically assume their operating position. A two-way latch is provided for fixation in either operating position. The so designed cutting drum permits high operational reliability in robust operating conditions.

Abstract: A bulk material loading and unloading facility for sea-going ships with displaceably arranged bulk material loading and unloading devices (23). Instead of a pier or a dock facility and a shore-side storage facility equipped with stackers and reloading devices and the conveyor belt units needed for them, a trough-shaped bulk material storage facility (14) is arranged on the ocean bottom (3) at a water depth that is safely navigable for sea-going ships, and rails (22) are laid on the side walls (15) of the bulk material storage facility. Loading and unloading devices (23) travel on these rails, and the loading and unloading devices (23) convey bulk material from ships (28) into the trough-shaped storage facility (14), or onto a conveyor belt unit (25) leading from this storage facility directly to a bulk material processing facility (e.g., a coal-fired power plant). The loading and unloading devices (23) can also convey bulk material from the trough-shaped bulk material storage facility (14) onto the conveyor belt (25) or into ships (28).

Abstract: A movable continuous bulk material conveyer, especially for unloading ships. A steep-rise conveyor is provided that comprises a conveyor belt and a cover belt. The bulk material is thrown by two casting reels into the lower gap between the conveyor belt and the cover belt. Since during the meander-like removal of material from the hold of a ship, the position of the casting reels and the steep-rise conveyor relative to one another constantly changes, the shafts of the casting reels are pivotably connected via a quadrilateral articulation with the lower guide pulleys of the steep-rise conveyor, and are controlled by hydraulic pistons from a computer in such a way that the casting reels always pick up a constant stream of bulk material and throw this material in the direction of the angle bisector of the gap of the steep-rise conveyor.

Abstract: A method of strip mining coal or other minerals by way of continuous-operation winning equipment with a cylindrical winning tool that excavates strips with a more or less rectangular section. The rectangle is approximately as wide as the tool and no higher than half the tool's diameter as the equipment advances. The equipment is connected by a system of conveyor belts to a loader that deposits the excavated minerals onto a face conveyor. The face conveyor can be shifted more or less parallel to the direction the equipment moves in. A quadrilateral district is exposed as the equipment travels first along one short side, then along one long side, and finally along the other short side. Its tool lifts out a strip of mineral. The equipment turns at each end along an arc of approximately one eighth to one fourth of a circle to end up in a ramp surface that occurs when the tool is lowered and raised. A terraced wall is created by lifting out many strips as the equipment's travel is shifted to the side. The ramps of the various strips combine into one ramp surface with a slope that allows the equipment to travel over it under its own power. Once the wall has been created, the blocks of mineral in the district, which comprise several levels one above another and one adjacent to another, are mined in succession starting with the floor created along with the wall. Each level comprises an equal number of adjacent strips.

Abstract: Instead of teeth or similar cutting or loosening means, oscillating nozzles are arranged on the outer backs and the outer side walls of the buckets of the bucketwheel of a bucketwheel excavator, the nozzles being capable of being supplied with liquid, in particular water, at high pressure. These nozzles enable the excavator to strip or mine deposits of high hardness and strength as well as highly abrasive deposits with reduced outage periods and reduced force required for digging as well as lower capital costs and operating costs. In addition to the oscillating nozzles, fixed nozzles may additionally be provided which produce cuts in the material to be excavated whereby the formation of large lumps is prevented.

Abstract: A pivoting transfer means for a jet of bulk material between a first cover belt conveyor and a second cover belt conveyor. The bulk material leaves the cover belt conveyor in the area of the tail pulleys and enters the receiving mouth of a second cover belt conveyor as a free jet of bulk material. Both cover belt conveyors are arranged pivotably in relation to one another around a pivot axis. The receiving mouth of the cover belt conveyor is limited by the bottom belt, the cover belt and the side walls. The jet of bulk material is deflected from the vertical into the horizontal direction of delivery within the receiving mouth. The first belt conveyor may be arranged at a higher level with the second cover belt conveyor arranged thereunder. However, the second cover belt conveyor may also be arranged at a higher level with the first cover belt conveyor arranged thereunder wherein the transfer is still from the first cover belt conveyor to the second cover belt conveyor.
