Detailed Description
Referring to fig. 1 to 3, the present invention provides an anti-jamming gangue loading system, which has the following embodiments.
The utility model provides a specific structure of coal gangue loading system that anti-sticking was stifled includes band conveyer 1, mechanical screening plant 2, the measuring hopper 3, laser monitoring appearance 4, pile coal protector 5 and position in a storehouse measuring apparatu 6, through band conveyer 1, the screening and the transportation of raw coal and waste rock have been realized to mechanical screening plant 2 and measuring hopper 3's cooperation, monitoring and protection to coal gangue loading system have been realized through laser monitoring appearance 4, pile coal protector 5 and position in a storehouse measuring apparatu 6's cooperation monitoring, avoid the stifled phenomenon of card. Wherein band conveyer 1 transports coal and waste rock to mechanical screening plant 2 through the belt, and mechanical screening plant distributes raw coal and waste rock to raw coal constant weight hopper 3 and waste rock constant weight hopper 3 respectively, and constant weight hopper 3 loads raw coal or waste rock to mine car or belt transportation. Belt conveyor 1 sets up highly being greater than mechanical screening plant 2 sets up highly, and mechanical screening plant 2 sets up highly being greater than quantitative hopper 3 sets up highly, and further avoiding the card stifled through setting up reasonable high gradient to practice thrift the cost. The entrance of the quantitative hopper 3 is also provided with a coal receiving plate 7, so that the weight sensor of the quantitative hopper 3 is prevented from being damaged by coal, and the coal receiving plate 7 is obliquely arranged relative to the coal receiving direction of the quantitative hopper 3.
