The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Development machine and continuous miner loader mechanism all extensively adopted the star wheel type loader mechanism both at home and abroad in recent years, and it is a kind of novel loader mechanism, adopted hydraulic motor directly to drive the mode of star-wheel, and transmission is simple, stressed evenly, running is steady and delivered payload capability is high.Fig. 1 is the utility model star wheel type development machine loader mechanism embodiment one structural representation, and as shown in the figure, the star wheel type development machine loader mechanism of present embodiment comprises shovel board 11, left star-wheel 13 and right star-wheel 14.Wherein, left star-wheel 13 and right star-wheel 14 are installed in the left and right sides in shovel board 11 fronts respectively; On the position of the back side corresponding to left star-wheel 13 and right star-wheel 14 of shovel board 11, be separately installed with the drive unit 12 of development machine scratch board conveyor structure; The driven pulley device 15 of this scratch board conveyor structure also is installed at the back side of shovel board 11, and driven pulley device 15 is connected with drive unit 12 and matches, driven by drive unit 12.
As shown in Figure 2, the drive unit 12 of the foregoing description star wheel type development machine loader mechanism is made up of motor seat 121, motor 122 and rotating disc 123.Wherein, motor seat 121 directly is located on the shovel board 11; 122 in motor is installed on the motor seat 121, and the output shaft of motor 122 connects rotating disc 123; 123 of rotating discs continue sheathed star-wheels (among the figure be example with right star-wheel 14), break coal thereby star-wheel rotate under the drive of motor 122.Need to prove that loading star-wheel has straight shape, straight oblique and three kinds of form of structure of knife-edge, is illustrated in figure 2 as the knife-edge structure in the present embodiment, other two kinds existing in the prior art extensively employings are not given unnecessary details herein.
In the star wheel type development machine loader mechanism of the technical program, left star-wheel and right star-wheel are equipped with a plurality of star-wheel jaws, are generally three-jaw, four paws or six pawls.Star wheel rotate speed 50r/min (rev/min) when following, the star-wheel shape is little to loading influential effect; But after star wheel rotate speed surpasses 50r/min, the pawl of star-wheel with knife-edge for well.Below, for improving the running efficiency of star wheel type development machine loader mechanism better, the star wheel type development machine loader mechanism of embodiment two further improves the jaw of star-wheel.As shown in Figure 3, the star wheel type development machine loader mechanism of present embodiment is identical with the structure overwhelming majority of embodiment one, all equally by shovel board 11, drive unit 12, left star-wheel 13, right star-wheel 14 and driven pulley device 15.The difference of two embodiment only is the improvement of star-wheel, as shown in Figure 4, the star wheel type development machine loader mechanism of present embodiment is equipped with pick 132 on the sidewall perpendicular to the star-wheel wheel face of star-wheel (is example with left star-wheel 13) jaw 131, and pick 132 is the direction of rotation settings along star-wheel 13.Further shown in the A-A schematic cross-section of Fig. 5, above-mentioned pick 132 is fixed on the star-wheel jaw 131 by circlip 133.
In sum, the star wheel type development machine loader mechanism that technical solutions of the utility model provide can broken coal cinder in driving, thereby the coal cinder that drops in the assurance tunneling process can in time be transported by the follow-up transport establishment of shovel board, thereby has improved the complete machine performance of development machine.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, all should fall into the scope of the utility model protection.
