Embodiment
See Fig. 1, Fig. 2, the structural type in the present embodiment with the detachable gas injection mechanism of dust reduction capability is: to be arranged on by gas injection axle 12 on chassis 13 and to be together elevated with chassis; Gas injection block 3 is fixedly supported on the output shaft in vertical pneumatic element 2, and gas injection block 3 can be elevated under the driving of pneumatic element 2; Injecting hole 3a is positioned at the front end of gas injection block 3, and injecting hole 3a is coaxial with gas injection axle 12; In the front end of gas injection block 3, be positioned at injecting hole 3a position place and be provided with longitudinal guide groove, in longitudinal guide groove, arrange a pair can the dust cover 7 of longitudinally guide groove slide in opposition, close up closed injecting hole 3a in opposite directions with a pair dust cover 7, relative separation then opens injecting hole 3a; Utilize the rising of the decline of gas injection axle 12 and gas injection block 3 open dust cover 7 and gas injection axle 12 is docked with injecting hole, utilize spring to make dust cover 7 automatically close up closed injecting hole 3a.
In concrete enforcement, corresponding vibrational power flow also comprises:
Arrange chassis 13 to be supported by support block 9 after decline, and detect the falling head of chassis 13 with sensor 10, the Trig control signal using the output signal of sensor 10 as pneumatic element 2.
A pair dust cover 7 is by being fitted in dust cover chute in the spring 6 longitudinally arranged in respective outside, the inner side edge that a pair dust cover 7 is on relative position is respectively hypotenuse, a pair dust cover 7 closed up in opposite directions is formed as " V " shape groove at butt joint edge, when the gas injection axle 12 declined with chassis 13 promotes downwards in " V " shape groove, because downward thrust makes a pair dust cover 7 relative separation on hypotenuse; And then gas injection axle 12 is docked with injecting hole 3a, meanwhile, spring 6 is compression, and after gas injection axle 12 gos up, due to the pressure of spring 6, a pair dust cover 7 recovers the mode bit closed up again, and injecting hole 3a is closed.
Be fixedly installed block 5 at the two ends of longitudinal guide groove, spring 6 is fitted between block 5 and the dust cover 7 of corresponding side, arranges seal ring 8 at the orifice part of injecting hole 3a, docks with being formed between injecting hole to seal to make gas injection axle; Be fixedly installed base 1, base 1 is fixedly installed on roller bed, and pneumatic element 2 is in the side being vertically fixedly installed on base 1, and gas injection block 3 is in the top of base 1; The gas-tpe fitting 4 be connected with injecting hole 3a is fixedly installed the outside of gas injection block 3, and sensor 10 is fixedly installed on the top of base 1 by sensor stand 11.
In working procedure: as shown in Figure 2, when chassis 13 arrives gas injection mechanism position, gas injection axle 12 is on the position that also injecting hole 3a is coaxial, subsequently, drop to chassis 13 by chassis 13 with gas injection axle 12 and contact with support 9 pieces, now gas injection axle 12 not yet contacts with dust cover 7, and as shown in Figure 3, injecting hole 3a still keeps in the closed condition, meanwhile, put in place because chassis 13 declines, sensor 10 detects signal, and by signal transmission to control unit, control unit exports to pneumatic element 2 the output shaft jacking that control signal makes pneumatic element 2 immediately, move upward with gas injection block 3 with this, gas injection axle 12 is caused to form downward promotion to dust cover 7 in " V " shape groove, under the thrust of gas injection axle 12, due to the effect of substantially horizontal component, a pair dust cover 7 moves towards both sides in opposite directions, injecting hole 3a opens thereupon, dock until gas injection axle 12 is sealed with injecting hole 3a by seal ring 8, as shown in Figure 4, now be gas injection working state, when chassis 13 completes corresponding course of action, gas injection terminates, now chassis 13 upwards lifting, pneumatic element 2 declines with gas injection block 3 simultaneously, gas injection axle 12 exits " V " shape groove, dust cover 7 resets under the pressure of spring 6, injecting hole 3a reverts to closedown, complete the process of automatic on-off.
