Most of boom-type roadheader shovel board adopts the star-wheel mode to transport the material that cut gets off, along with the attention of country to the coal production operating environment, development machine adopts spraying to carry out dedusting in cutting course, form the pasty state coal slime after the coal that a large amount of water for dust removal gets off with cut etc. mixes, 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, the original place rotation, produce accumulation when coal slime can not get effectively transportation, its viscosity makes its bonding, though star-wheel can be transported the bottom coal slime, but the upper strata coal slime is formed shelly, star-wheel that can only the original place rotation can not make in time to form shelly and obtain the upper strata coal slime and collapse downwards, causes coal slime further to be piled up, and is unfavorable for producing.
Summary of the invention
The object of the invention is: practical problem that can only the 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 object of the present invention is achieved like this: 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 the star-wheel center through runner plate, it is characterized in that, also comprise clamp flange and swivel bearing in drive unit, described gear drive is planet circular system, contain three equally distributed planetary gears in planet circular system, 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, be provided with swivel bearing between ring gear and planet carrier, 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 present invention, power source is fixedly connected with clamp flange by bolt, and clamp flange is fixedly connected with runner plate by fastening bolt.
In the present invention, described driving planetary gear is fixedly connected with and refers to output shaft: drive between planetary gear and output shaft by the interference stationary fit, or drive between planetary gear and output shaft by inside and outside spline fitted, or locate and coordinate by key between driving planetary gear and output shaft.
The application of star wheel driving device for shovel board in a kind of above-mentioned development machine, it is characterized in that, the output shaft of star-wheel-drive device is fixedly connected with to rear formation star-wheel assembly with the star-wheel center, the star-wheel in the star-wheel assembly and output shaft synchronous rotation, driven and revolved round the sun around power shaft by planet carrier simultaneously.
In the application of described star wheel driving device for shovel board, in the shovel board of the star-wheel assembly that contains two same specifications, during assembling on the revolution track 180 ° of two star-wheel assembly rotation axle center initial phase differences; In work, the output speed equidirectional of drive unit is contrary, and star-wheel direction of rotation in rotation and revolution is contrary.
The invention has the advantages that: in shovel board of development machine star-wheel mechanism of the present invention, in the time of the star-wheel rotation, with planet carrier, revolve round the sun, revolution makes the star-wheel of shovel board star-wheel mechanism of the present invention that the larger rewinding space of dead axle star-wheel of radiuses such as comparing can be provided, can better stir coal slime, prevent the coal slime bonding, improve the transport capacity of coal slime.
Simultaneously, control the planetary mechanism gearratio, make every side star-wheel shovel board that revolves round the sun a pawl be arranged from forwarding shovel board to foremost time foremost simultaneously, the 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.
