Abstract
The utility model relates to an underground bulk material conveyer for coal mines, in particular to a scraper conveyer, which comprises a driving head transmission, a transition chute, a central chute, a central chain chute, a scraping chain plate and a tail assembly. The utility model is characterized in that single sprocket is arranged at the central section of the head in the head transmission; a spline housing, the sprocket and a sleeve are welded in to a head transmission drum; a blind shaft and a bearing support are connected with a side plate of a frame, thereby a spline of a reducer output shaft is connected with a spline of the head transmission drum. The utility model has the advantages of even stress of the chain, less liability to chain breakage, convenient disassembly since the reducer is directly inserted in the spline of the head transmission drum, good alignment effect and convenient maintenance.
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 SGB420/40 (SGW40T changes) 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 middle strand 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, tail is formed, it is characterized in that, in the head drive device, single sprocket wheel is arranged in the head middle part, two spline housings and two overcoats and chain wheel set are welded into the head driving drum, the head driving drum links to each other with the headstock side plate by blind axle, and the spline of speed reducer output shaft links to each other with the head driving drum.
This structure of the utility model makes the limit two strands become middle strand, and chain is stressed more even, and chain rupture is few, and reductor directly inserts in the head driving drum spline, 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 3, sprocket wheel 4 and overcoat 5 assembly welding together become the head driving drum, connect framework lateral plate 7 by blind axle 6 and bearing seat 8, head driving drum spline passes to sprocket wheel 4 to the kinetic energy that reductor 1 output shaft 2 passes over by the head driving drum again, and sprocket wheel 4 rotates the drive scraper plate and chain carries out the transportation of bulk material.
Claims (1)
