Multidirectional discharging method of mobile discharging car
InactiveCN102249095AFlexible unloading methodIncrease economic benefitsConveyorsLoading/unloadingEconomic benefitsEnvironmental quality
The invention relates to a multidirectional discharging method of a mobile discharging car, and belongs to the technical field of a bulk material discharging device. The multidirectional discharging method is characterized in that materials are transferred into a belt conveyor at the lower part through a funnel and then are transported to the position above a discharging point for discharge; and by adjusting the horizontal distance between the discharging point of the belt conveyor and the outlet of the funnel, discharging position is adjusted without increasing overall height of the conveyor. The multidirectional discharging method has the beneficial effects that the materials can be flexibly discharged in multiple directions as required; the structure is compact, thus saving equipment installation space; a long chute is not used, thus avoiding phenomena such as material aggregation and blockage; by effectively controlling equipment height, discharging height difference is decreased, and dust generated during the material transfer process is reduced, and good dedusting and environmental protection effect can be obtained by utilizing dedusting equipment; and steel structural members in the equipment are simplified and diminished, thus the equipment can be conveniently installed and simply debugged, operated and maintained, and good economic benefit can be obtained. The mobile discharging car is particularly applicable to workplaces with narrow plant space and higher requirement on environmental quality.
