Description
Technical field
The utility model relates to boom-type roadheader, is specially a kind of shovel board of development machine star-wheel mechanism.
Background technology
Most of boom-type roadheader shovel board adopts star-wheel mode to transport the material that cut gets off, along with the attention of country to coal production operating environment, development machine adopts spraying to carry out dedusting in cutting course, after the coal that a large amount of water for dust removal gets off with cut etc. mixes, form pasty state coal slime, very easily viscous causes conevying efficiency low in star-wheel.At present, the type of drive of star-wheel is generally that drive unit drives through gear drive, original place rotation, when coal slime can not get effectively transportation, produce accumulation, its viscosity makes its bonding, though star-wheel can be transported bottom coal slime, but upper strata coal slime is formed shelly, star-wheel that can only original place rotation can not make in time to form shelly and obtain upper strata coal slime and collapse downwards, causes coal slime further to be piled up, and is unfavorable for producing.
Utility model content
The utility model object is: practical problem that can only original place rotation at star-wheel for the most of boom-type roadheader shovel board of tradition, a kind of new star wheel driving device for shovel board in a kind of new development machine that provides is provided, and is assembled into the New Star wheel assembly that can rotation can revolve round the sun again with it.
The purpose of this utility model is achieved in that star-wheel-drive device in a kind of shovel board of development machine, comprise power source and gear drive, the power shaft of gear drive docks with power source, output shaft is fixedly connected with star-wheel center through runner plate, it is characterized in that, in drive unit, also comprise clamp flange and swivel bearing, described gear drive is planet circular system, in planet circular system, contain three equally distributed planetary gears, the ring gear of planet circular system is fixedly connected with clamp flange by bolt, clamp flange is fixedly connected with runner plate by bolt, between ring gear and planet carrier, be provided with swivel bearing, the sun wheel shaft of planet circular system is power shaft, a planetary gear in three planetary gears is for driving planetary gear, and driving the pivot pin of planetary gear is output shaft, and output shaft on planet carrier, drives planetary gear to be fixedly connected with output shaft by bearings.
In the utility model, power source is fixedly connected with clamp flange by bolt, and clamp flange is fixedly connected with runner plate by fastening bolt.
In the utility model, described driving planetary gear is fixedly connected with and refers to output shaft: drive between planetary gear and output shaft by interference stationary fit, or drive between planetary gear and output shaft by inside and outside spline fitted, or by key, locate and coordinate between driving planetary gear and output shaft.
The utility model advantage is: in the utility model shovel board of development machine star-wheel mechanism, in the time of star-wheel rotation, with planet carrier, revolve round the sun, revolution makes the star-wheel of the utility model shovel board star-wheel mechanism that the larger rewinding space of dead axle star-wheel of radiuses such as comparing can be provided, can better stir coal slime, prevent coal slime bonding, improve the transport capacity of coal slime.
Simultaneously, control planetary mechanism gearratio, make every side star-wheel shovel board that revolves round the sun have a pawl from forwarding shovel board to foremost time foremost simultaneously, both sides star-wheel back and forth has a pawl to arrive shovel board foremost in turn, form the rake material action of similar crab claw, increase the rewinding ability of star-wheel.
