Description

Large conveying quantity chain scraper feeder

The utility model relates to feeder, is the large conveying quantity chain scraper feeder that uses under a kind of coal mine.

At present, the feeder kind of domestic use is a lot, but be suitable under the coal mine seldom, a large amount of feeders that use are reciprocating feeders under the coal mine, and its structure is that a little downward-sloping hopper is arranged, and its removable bottom is bearing on several groups of carrying rollers, the crank motion that actuating device moves forward and backward base plate by a crank mechanism, material is discharged in the hopper from feed bin when travelling forward, and when moving backward, material is released by the hopper rear wall and is discharged into feeding equipment.Its feeding coal is to adjust by the method that changes the base plate stroke, fine setting realizes that by gate this feeder result of use in middle-size and small-size mine is fair, but along with the development of coal industry, large-scale mine is increasing, especially the appearance of high-yield and high-efficiency mine, the reciprocating feeder ability is little, and the separate unit feed often can not meet requirements, if adopt many feeds simultaneously, chamber is oversize, and difficulty in arrangement is technical, all infeasible economically.

The purpose of this utility model provides a kind of large conveying quantity chain scraper feeder, and little to solve existing reciprocating feeder ability, the separate unit feed can not meet the demands, if many while feeds, chamber is oversize, difficulty in arrangement, technical all infeasible economically problem.

The purpose of this utility model is achieved in that this machine is made up of headstock, aircraft tail shelf, driving device, chain wheel set, scraper chain, stern barrel, headstock, aircraft tail shelf and hopper are connected as a single entity by bolt, there is bearing in headstock one outside, by bolt driving device is arranged, the chain wheel set that driving device drives in the headstock is rotated, chain wheel set comprises 3 sprocket wheels and four and half cylinders, is assembled by bolt; Chain wheel set drives 3 scraper chain motions, the staggered scraper plate that is evenly equipped with on the scraper chain, be provided with slide rail in the aircraft tail shelf biside plate outside, free-running fit has slide block on the slide rail, slide block is provided with chain tension adjusting device, stern barrel passes the side plate hole by axle and is fixed on the slide block, stern barrel is provided with the guide groove that adapts with 3 scraper chains, make scraper chain middle plate in hopper make gyroscopic movement up and down, hopper is box-shaped, and biside plate middle part solid welding has middle plate, lower end snail ties and is connected to base plate, upper end snail ties and is connected to baffle plate, and the baffle plate outside is provided with bolt hole, and bolted connection has cover plate on the baffle plate, hopper is provided with the scalable gate, one side is provided with chute, and chute is provided with funnel, and funnel is by being bolted to the feed bin below.

Chain tension adjusting device is to be combined with two setting nuts by solid welding on the screw mandrel on the slide block, screw mandrel, by being fixed on the forward and backward plate supporting on the slide rail terminal tailstock, comes tight chain by setting nut adjusting slider position.

Driving device is to be rotated by the chain wheel set that elastic coupling and retarder drive in the headstock by two speed motor, and electrical motor and retarder are connected as a single entity with cover, and the retarder outside is provided with otic placode, and it is corresponding with the headstock bearing.

This utility model compared with prior art has the following advantages: 1) the feed ability is big, per hour can reach 2000 tons; 2) adopt two speed motor, both can solve the heavy-load start problem, can realize the switching of two kinds of feeding coals again; 3) hopper is box-shaped, and integral rigidity is good, and airtight protection against dust is good; 4) compact conformation, required down-hole chamber size is little; 5) scraper chain adopts 3 chain haulage modes, and the scraper plate force-bearing situation is good, and common component is many, and manufacturing process is simple, and productive costs is low; 6) mandatory feed also can guarantee that materials flow is even, and is safe and reliable.

Be described further below in conjunction with accompanying drawing:
