Abstract
The utility model belongs to a coal mine underground bulk material conveying device, consisting of a head transmission device, a transition trough, a middle trough, a middle chain trough, a chain scraping plate, a tail frame and a thrust beam. The utility model is characterized in that two chain wheels in the head transmission device are arranged in the middle part of a head shaft; the head shaft is connected with a chain wheel and a bearing seat internal spline sleeve by a spline to assemble a head transmission assembly; the head transmission assembly is connected with a frame side plate by an echelon bolt; an output shaft of a reducer is connected with the spline sleeve by the spline. The utility model has the advantages of uniform forcing of the chain, little chain broken, convenient disassembly and assembly, good centering effect and convenient maintenance, with the reducer directly inserted into the spline sleeve.
Description
Technical field: the utility model belongs to the conveying arrangement of loose unpacked material under a kind of coal mine, specifically, is a kind of slat conveyer that is used for transporting in the underworkings of colliery coal etc.
Background technology: slat conveyer is one of visual plant of colliery down-hole mining transport systems, China's middle and small scale coal mine generally utilizes SGW-40T type limit double chain conveyor at present, this conveyer two strands is arranged in both sides, article two, chain unbalance stress, operation is even more serious under the intermediate channel case of bending, cause phenomenons such as easy chain rupture bar in service or sprocket wheel broken teeth, during the scraper plate distortion, by the easy chain rupture of sprocket wheel.In addition, this type running part adopts half cylinder, relies on bolt with key blind axle to be connected together with the deceleration arbor again, remove and install all cumbersome, when the stressed key that rolls easily than greatly the time.
At above-mentioned situation, the utility model proposes a kind of double center chain slat conveyer, its chain is stressed evenly, can overcome the problem that chain rupture and dismounting inconvenience are easily rolled aspects such as key.
Summary of the invention: the utility model is realized in the following ways: the utility model by head drive device, transitional slot, intermediate channel, middle part chain link groove, scrape carrier bar, baffle plate, tail, passing beam and form, it is characterized in that, in the head drive device, two sprocket wheels are arranged in head axle middle part, the head axle is connected with spline housing in the bearing seat by spline and sprocket wheel and forms the head drive assembly, the head drive assembly links to each other with framework lateral plate by trapezoidal bolt, and speed reducer output shaft links to each other with spline housing by spline.
This structure of the utility model makes the limit two strands become double center chain, and chain is stressed more even, and chain rupture is few, and reductor directly inserts in the spline housing, easy accessibility, and centering is effective, is convenient to maintenance, is difficult for rolling key.
Description of drawings: accompanying drawing is the structural representation of the utility model double center chain slat conveyer head drive device.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing.Spline housing 5 in head axle 3, sprocket wheel 2 and the bearing seat 4 is formed the head drive assembly together, by trapezoidal bolted connection framework lateral plate 1, head axle 3 passes to sprocket wheel 2 to the kinetic energy that reductor 6 passes over by spline again by spline housing 5, and sprocket wheel 2 rotates the drive scraper plate and chain carries out the transportation of bulk material.
