Abstract
The utility model discloses a scraper conveyer for low coal seam, which solves the problem that the existing scraper conveyer cannot meet the production and working requirements for high yield and high efficiency on a working face of the low coal seam. The scraper conveyer comprises a machine head (3), a machine tail (9) and a middle plate (6), wherein the top parts of the machine head (3), the machine tail (9) and the middle plate (6) are arranged on the same horizontal plane; the machine head (3) and the machine tail (9) are respectively arranged under the horizontal plane; machine-head supporting cushion blocks (5) are movably arranged between a base (4) of the machine head and the bottom surface of a roadway of the machine head (2); and machine-tail supporting blocks (8) are movably arranged between a base (7) of the machine tail and the bottom surface of a roadway of the machine tail (10). The scraper conveyer disclosed by the utility model has the advantages that the production and working requirements for high yield and high efficiency on the working face of the low coal seam are met and the coal washing difficulty is reduced.
Description
Technical field
The utility model relates to a kind of downhole coal mine and uses drag conveyor, particularly a kind of drag conveyor that is applicable to thin seam working surface.
Background technology
Scratch board conveyor is a kind of downhole coal mine that is used for, and realizes the Transport Machinery of coal-face fortune, the mechanization of loading, unloading coal.At present; The down-hole is mining, and the girdle drag conveyor all is a head bending upwards type drag conveyor; Most of thin seam working surface coal seam thickness has only about 1.2 meters, and head bending upwards type drag conveyor chain-drive section height causes with hydraulic support to interfere just near 1.2 meters; For head bending upwards type drag conveyor and hydraulic support are not interfered; Complete equipment can normally move; Coal-winning machine must cut a part of stone, makes between head bending upwards type drag conveyor and the hydraulic support and leaves certain space, and this has just aggravated the wearing and tearing of the cut tooth of coal-winning machine; Contain a large amount of stone in the coal, strengthened the coal washing difficulty; Increased the cost of whole process of production.Head bending upwards type drag conveyor can't satisfy the highly efficient and productive production work demand of thin seam working surface.
Summary of the invention
The utility model provides a kind of girdle drag conveyor, has solved existing drag conveyor and can't satisfy at thin seam working surface and realize the problem that the production work of high-yield and high-efficiency requires.
The utility model overcomes the above problems through following scheme:
A kind of girdle drag conveyor; Comprise head, tail and middle plate; The top of head, the top of tail and middle plate top are arranged on the same horizontal plane; Head and tail all are arranged on this horizontal plane below, between the bottom surface in machine head base and head tunnel, are movably set with the head lip block, between the bottom surface in tail base and tail tunnel, are movably set with the tail back-up block.
The head drive device that connects with headstock is arranged on the horizontal plane parallel with middle plate; Head drive device and middle plate are an angle of 90 degrees; The tail transmission device that connects with aircraft tail shelf is arranged on the horizontal plane parallel with middle plate, and tail transmission device and middle plate are an angle of 90 degrees.
The middle plate of curved formula drag conveyor is level under this head, and head tail height is consistent with intermediate channel, and the head tail can not interfere with hydraulic support, and coal-winning machine no longer need cut stone; The work plane baseplane is higher than tunnel baseplane, has guaranteed that the coal mining function is thorough the cutting of triangle coal, does not stay the triangle coal; The head tail is provided with adjustable supporting seat, is suitable for the fluctuating of work plane.
The utility model has satisfied the production work demand of the high-yield and high-efficiency of thin seam working surface, has reduced the coal washing difficulty.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the head drive device of the utility model.
The specific embodiment
A kind of girdle drag conveyor; Comprise head 3, tail 9 and middle plate 6; The top of the top of head 3, tail 9 and middle plate 6 tops are arranged on the same horizontal plane; Head 3 all is arranged on this horizontal plane below with tail 9, between the bottom surface in machine head base 4 and head tunnel 2, is movably set with head lip block 5, between the bottom surface in tail base 7 and tail tunnel 10, is movably set with tail back-up block 8.
Be arranged on the horizontal plane parallel with head drive device 11 that headstock 12 connects with middle plate 6; Head drive device 11 is an angle of 90 degrees with middle plate 6; Be arranged on the horizontal plane parallel with middle plate 6 with tail transmission device that aircraft tail shelf connects, tail transmission device and middle plate 6 are an angle of 90 degrees.
The straight layout of middle plate of the head tail of drag conveyor, in the laying length of whole drag conveyor, the middle plate 6 of head 3, tail 9 and intermediate channel is level; The haulage gear of coal-winning machine, promptly rack rails also is to be level; Guarantee coal-winning machine when entire working surface is moved, the pivot angle and the cut degree of depth can not change under fuselage height, the cylinder, have solved the problem of staying the triangle coal.
The down-hole coal excavation work plane is yo-yo; Through between the bottom surface in machine head base 4 and head tunnel 2, being movably set with head lip block 5; Between the bottom surface in tail base 7 and tail tunnel 10, be movably set with tail back-up block 8, make the middle plate of head 3, tail 9 and intermediate channel be horizontal arrangement all the time.
