Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the structural representation of another embodiment.

Fig. 4 is the A-A sectional view of Fig. 3.

Fig. 5 is that the B of Fig. 3 is to view.

The primary structure of rotary obstacle sucker shown in Figure 1 is described in the 4th section in this paper, no longer repeats herein.Need to prove that aspiration channel 1 is an ascending/decending, promptly when sucker is not worked, the sucker lifting is had certain distance with the road surface, guarantee normal vehicle operation, when sucker is worked, then it is put down.On the cleaning vehicle, also can install a location mechanism in addition, make that half-twist was not regained in car body when sucker was not worked, be fixed, not influence the cruising of vehicle.Because described elevating mechanism, detent mechanism are known technology, this paper does not give unnecessary details.One round brush 10 is arranged in the sucker among Fig. 1,2 (9), and there is driving wheel 14 at two ends, driven pulley 13, and pass through the motor 8 that roller brush shaft 16 links to each other with driving wheel, the effect of motor is to drive the round brush rotation.Consider concrete road environment, injustice might be arranged or shorter and smaller obstruction is arranged, sucker (9) can be made bipartial, the upper end links to each other by knee-action hinge 3, when sucker is run into obstruction in traveling process like this, can upwarp and stride across obstacle (as the side of hard shoulder), this knee-action hinge 3 should possess reset function, makes sucker can press close to road cleaning all the time.

A is to expression road-sweeper direction of advance among Fig. 2, sucker 9 and a are to vertical during work, and stretch out outside the car body, can be inserted with in the road surface of obstruction, the stressed angle [alpha] of rotating backward when running into obstruction, α be 0 °-90 ° (0 ° of finger sucker and a when being vertical angle, 90 ° of finger suckers rotate backward with a when opposite).

The another kind of implementation of the utility model is telescopic obstacle sucker, shown in Fig. 3,4,5.Its groundwork principle is identical with rotation suction cup with good effect, but its structure changes to some extent, its inlet scoop 2 connects ascending/decending aspiration channel 1 by rotary flange dish 6, inlet scoop 2 one sides and assisted sucking disc 20 are fixing, opposite side is fixed with air port cover plate 23, V-type driving lever 11 is by driving lever support 22, and shift lever axis 7 is fixed on the inlet scoop, in the both sides of assisted sucking disc coil tension spring 21 is arranged; Flexible sucker 19 tops of strip have the opening greater than the inlet scoop width; This sucker 19 inserts in inlet scoops 2, is provided with pulley 17 at the sucker top, and this pulley links to each other with the V-type driving lever, the chute 24 that the band rubber that has the confession pulley to slide on the cover plate of air port seals, and sucker 19 should be positioned at vehicle one side, and vertical with longitudinal direction of car.

When the road-sweeper that telescopic obstacle sucker is housed moves ahead work, sucker 19 inserts between the hard shoulder and cleans pavement garbage, when obstruction, driving lever 11 is obstructed and rotates backward, and by pulley 17, chute 24 promotes suckers 19 and inwardly shrinks also compression spring 21, escape obstruction, block the air port because the opening on sucker top is wider than the width of inlet scoop so be unlikely this moment, and sucker 19 and assisted sucking disc 20 all can carry out cleaning works.When the cut-through thing, resistance disappears on the driving lever, and sucker 19 stretches out again under the effect of coil tension spring, inserts and continues cleaning between the hard shoulder.Hence one can see that, and the sucker of this kind structure also can be realized the purpose of this utility model.
