Abstract
The utility model relates to a colliery underground operation face is scraper blade elevating conveyor field for the crossheading, specifically is a can sieve formula scraper blade elevating conveyor, including scraper conveyor and elevating conveyor. Can sieve formula scraper blade elevating conveyor, through directly transporting nut coal and smalls without the breaker in advance, remain the mode that massive coal and waste rock transported again after the breaker breakage, improved former coal cinder rate from the source, improved the economic benefits of coal, be applicable to the colliery underground operation face crossheading that is not less than 2.8 meters.
Description
Technical field
The utility model relates to underground coal mine return airway scraper blade elevating conveyor field, and specifically one can screening type scraper blade elevating conveyor.
Background technology
Under the severe situation that supply exceed demand of national coal market, coal price keeps falling, and the requirement of user to coal is also more and more higher.Traditional crushing engine adopts one-pass mode, causes the block rate of coal to decline, inefficiency, studies a kind of downhole crossheading scraper blade elevating conveyor improving the block rate of raw coal from source extremely urgent.
Summary of the invention
The utility model is in order to improve raw coal scuttle, and providing one can screening type scraper blade elevating conveyor.
The utility model is achieved through the following technical solutions: can screening type scraper blade elevating conveyor, comprise drag conveyor and elevating conveyor, described elevating conveyor comprises bridge section and the section of landing, the section of landing free end upwards rises and is connected with the crushing engine port of export, drag conveyor afterbody upwards swells and to be connected with a upper sieve point transportation system, the afterbody of upper sieve point transportation system is connected with crushing engine arrival end, the some screening elongated holes of hole body afterbody towards cell body center line are had in the cell body of this upper sieve point transportation system, and the hole body afterbody of each screening elongated hole relative to front portion closer to crushing engine, a upper sieve point transportation system bottom is provided with scraper plate transportation system of lower floor, be positioned at and land the scraper plate transportation system of lower floor of pars infrasegmentalis and extend laterally and rise and exceed the section of landing, and by break away bucket with land intersegmental part and be connected.
During concrete use, can according to actual block coal rate by the small coal of below 100 to 150mm and smalls without crushing engine, scraper plate transportation system of lower floor is drained to by the screening elongated hole of upper sieve point transportation system, then deliver to elevating conveyor by sideslip bucket, transport again after the coal of residue bulk and spoil are transported to crusher in crushing by a upper sieve point transportation system.In addition, each screening elongated hole towards design along the direction of scraper chain, the generation of the chain that can prevent from stumbling.
Described in the utility model can screening type scraper blade elevating conveyor, by in advance small coal and smalls directly being transported without crushing engine, the mode that the coal of residue bulk and spoil transport after crusher in crushing again, raw coal scuttle is improve from source, improve the economic benefit of coal, be applicable to the underground coal mine return airway being not less than 2.8 meters.
