Abstract
The utility model relates to a screw coal conveyer for the unattended working face of an ultrathin coal layer during exploitation. The utility model is characterized in that the screw coal conveyer is formed in the way that a plurality of segments of rollers welded with spiral blades and a supporting seat provided with an arc-shaped coal blocking plate are installed into a whole, wherein the head part is connected with a power system, and the tail part is provided with a machine layer seat; thus, the whole body of the screw coal conveyer is formed. After the working face adopts deep holes for blasting, when the rollers rotate after the screw coal conveyer is started, the screw coal conveyer is driven to move forward by a hydraulic system in a small winch type to convey the coal on the working face. Because an operator does not need to enter the working face to work after the screw coal conveyer is adopted, the utility model solves the coal conveying problem of the working face with an ultrathin coal layer.
Description
The utility model relates to the conveying equipment that down-hole coal excavation is used, and belongs to the coal mining Transport Machinery.
In present down-hole coal excavation work, work plane fortune coal scratch board conveyor commonly used, this equipment only is suitable for being convenient to the work plane of personnel operation.But be lower than 0.5 meter for coal seam thickness, under the unapproachable situation of staff, though can adopt deep hole blasting, beat borehole along work plane, can fall the coal seam is quick-fried after the charge detonates, how coal breakage transports out from work plane also is a great problem.Urgent need will be invented a kind of coal handling plant of manless working face exploitation.
The purpose of this utility model is a kind of machinery that is suitable for transporting after the ultra-thin coal seam deep hole blasting coal of design, realizes the unmanned work of ultra-thin coal seam and the purpose of exploitation.
Scheme of the present utility model is: adopt the helical feed principle, design a kind of conveying machinery that runs through whole coal-face.This conveyer structure is as follows: be made up of head, tail seat and spiral cylinder supporting seat four parts.Head comprises motor and reducer, and reducer power output shaft and cylinder head are linked together with flange, and the cylinder afterbody is installed on the tail seat.Head, tail seat all are fixed on work plane up and down on the track flat car of two gallerys, and two flat cars are by the puffer or the hydraulic system traction that are arranged in the tunnel.
Supporting seat be used for back-up roller and fixedly spillplate use.Supporting seat structure is fixing upper support frame at the base two ends, arc spillplate on a side is fixing.Install for ease of mining face under mine, supporting seat also is a multi-section type.Cylinder is to be welded with helical blade on the tubulose barrel shell, installs for ease of the down-hole and also is designed to multi-section type, is provided with the drum shaft other end that has plug at an end of cylinder and is provided with socket.On a joint supporting seat, some joint cylinders can be installed.Connection by drum shaft between the cylinder and with the supporting seat connection together, constitute an integral body at work plane.
Good effect of the present utility model is, adopts spiral conveying principle, solved the transport issues of ultra-thin coal seam.Owing to adopt more piece plug jointing type, be convenient in down-hole installation demolition, and structure be very simple and reliable, easy operating.
In conjunction with the accompanying drawings, be described further again.Fig. 1 is the utility model overall schematic, and Fig. 2, Fig. 3 are wherein middle one section detailed construction figure of cylinder.Wherein Fig. 2 is the sectional drawing of front view, and Fig. 3 is the lateral view of Fig. 2.
Marginal data: 1-motor; The 2-reducer; The 3-flange; The spiral cylinder of 4-; The 5-spillplate; 6-tail seat; 7 blades; The 8-cylinder shell; 9 bearing shells lid; The drum shaft of 10 band plugs; The 11-bracing frame; The 12-base.
Among Fig. 1, motor 1 with form head after 2 of reducers are connected, the output shaft of reducer 2 is connected by the first segment cylinder 4 that flange 3 and head have flange, second joint is pegged graft by plug and socket with first segment, and the like, to the last the joint afterbody the axle be inserted in the tail seat 6.Fig. 2, Fig. 3 intermediate roll wherein one section structure are: being welded with bracing frame 11, one face down bondings at base 12 two ends has arc shelves coal plate 5; Be welded with screw blade 7 on the barrel shell 8, barrel shell one end is the drum shaft 10 that has plug, and the other end has socket.During integral installation, be positioned on the bracing frame of base after the cylinder stick that can two joints are above, card top bearing shell lid 9 is used bolt tightening.
