As can be seen from fig. 5 and 6, radial bores 14 are drilled in the circumferential side wall of the high-pressure gas roller 13 in the radial direction, as mounting bores for the mating assembly of corresponding high-pressure nozzles 15. Because the high-pressure nozzles 15 of each air knife are arranged along a straight line, after high-pressure air injection is carried out simultaneously, an air knife blowing and ejecting surface 48 and an air knife reflecting surface 49 are formed as shown in fig. 9, each air knife rotates from bottom to top in sequence along with the clockwise rotation of the high-pressure air roller 13, when the angle of each air knife is smaller, high-pressure air can contact with the ground to form the air knife reflecting surface 49, the ground attachments can be scooped up, along with the high-speed rotation of the high-pressure air roller 13, the air knife blowing and ejecting surface 48 moves upwards rapidly to lift the sweepings, the first air knife blowing and ejecting surface 48 quickly lifts the sweepings, then the second air knife blowing and the third air knife blowing and ejecting surface 48 continuously lift the sweepings in sequence, the sweepings are pushed to be close to the mouth of the air exhaust pipe to be sucked away, and the high-pressure air is transmitted. Further, the arc-shaped guide plate 67 shown in fig. 15 is arranged inside the front side of the cover body 1, the baffle plate 68 is obliquely arranged on the rear side of the air exhaust channel 32, and the arc-shaped guide plate 67 and the baffle plate 68 can be used for rapidly lifting the swept objects to the suction opening, so that the using effect and the sweeping efficiency are improved. The air draft channel can also be extended into the cover body 1 to reduce the height of the suction opening.

As can be seen from fig. 3 and 4, the semi-closed arc cover 11 is sleeved outside the high-pressure air roller 13 in a matching manner, as can be seen from fig. 5, two ends of the high-pressure air roller 13 are installed in the bearing seat through the end bearing 19, the bearing seat is installed in the shaft holes of the end plates (the first end plate 17 and the second end plate 18) on two sides of the semi-closed arc cover 11, and the semi-closed arc cover 11 is installed on the fixed seat 12.

And the air knife edge positioned in the semi-closed arc cover 11 is blocked by the semi-closed arc cover 11 without air outlet and is used as a wind-sheltering unit.

As shown in fig. 5 or fig. 7, a hollow rotating shaft 20 is connected to the center of one end wall of the high-pressure air roller 13, an air shaft 26 extends from the end of the hollow rotating shaft 20, the air shaft 26 is hermetically sleeved in the rotating sleeve 22 through an inner bearing 24 and a sealing ring 25, the high-pressure air pipe 23 is communicated in the rotating sleeve 22 and communicated with the cavity of the hollow rotating shaft 20, a solid rotating shaft 21 is connected to the center of the other end wall of the high-pressure air roller 13, the hollow rotating shaft 20 and the solid rotating shaft 21 are respectively sleeved in the bearings, and the high-pressure air roller 13 is driven by a driving mechanism to continuously rotate along.

As shown in fig. 3 and 7, the driving mechanism is provided with a driven gear 51 mounted on the end of the solid rotating shaft 21, i.e. on the gear shaft end 50, a driving gear 52 mounted on the rotating shaft of the driving motor, and the driving gear 52 is in transmission connection with the driven gear 51.

As described above, when the high-pressure air roller 13 rotates clockwise at a high speed, three air knives are always located in the area of the air outlet fan surface 65, each air knife moves from bottom to top quickly, and the forward movement and the backward movement circulate continuously, so that the ground attachments can be effectively scooped up and lifted to the vicinity of the suction opening, the cleaning speed is high, and the efficiency is high. The traditional cleaning mode that the rotary brush head is in contact with the ground is only suitable for low-speed operation and cannot be applied to highways with the speed of more than 60 KM/hour, and the traditional brush head type air suction hood has a series of problems of low cleaning efficiency, abrasion blocks and the like. The embodiment is suitable for fast cleaning of the expressway, provides cleaning equipment for the ground of the expressway, and has obvious cleaning efficiency and effect due to the common brush head type sweeper when being used on the common street. It is thus clear that the cover inner loop that induced drafts has been realized to the air knife and the exhaust passage that lie in the cover body 1 inside in this embodiment, lies in to have less interval d between the cover body 1 and the ground, can realize the atmospheric pressure compensation, so the feature of environmental protection is very strong, whether the watering can not cause the dust pollution problem, ensures its normal use all the time.

Namely, the proper rotation of the semi-closed arc cover 11 can control the orientation angle of the sector area, so that the best cleaning effect can be realized according to different road conditions. This embodiment is implemented using the configuration shown in fig. 3 and 4. In fig. 3 and 4, the semi-closed arc cover 11 is clamped by matching the fixing seat 12, a screw hole is vertically formed in the fixing seat 12, a jackscrew 64 is installed on the fixing seat, the jackscrew 64 is used for tightly jacking and connecting the semi-closed arc cover 11, the fixing seat 12 and the semi-closed arc cover 11 can be fixed into a whole after the jackscrew 64 is tightly jacked and adjusted, and the semi-closed arc cover 11 can be rotated to adjust the angle of the semi-closed arc cover 11 after the jackscrew 64 is loosened.

Example 3: the third kind is used for the high-pressure air roller type aspiration channel that the highway cleans, on the basis of embodiment 1, the actuating mechanism is different, this embodiment abandons to use transmission modes such as motor and gear or belt pulley, utilizes high-pressure air current as actuating mechanism, specifically distributes the annular recess as the ventilation slot along the circumference direction at high-pressure air roller 13 side, opens tangential hole along the tangential in the ventilation slot, installs tangential shower nozzle in the tangential hole, the wind sword is kept apart by the ventilation slot or wind sword and ventilation slot staggered distribution. Unlike the air knife formed by combining the high-pressure nozzles 15 in embodiment 1, the high-pressure nozzles 15 are perpendicular to the inner wall of the semi-closed arc-shaped cover 11 in the radial direction (normal line), i.e., the air flow direction, and therefore do not impart rotational power to the high-pressure air roller 13. But this embodiment can blow the 11 inner walls of semi-closed arc cover with the direction that is close to the tangent line with the air current through the tangential shower nozzle, and the air current can be discharged from the annular groove moreover to realize lasting tangent line air current, so last tangent line air current can blow and can cause high pressure air roller 13 to rotate under the reaction when hitting semi-closed arc cover 11, reach drive high pressure air roller 13 and rotate the purpose. The rotating speed of the high-pressure air roller 13 is influenced by the high-pressure degree and the air volume sprayed by the tangential nozzles, and after the air volume sprayed by the tangential nozzles is controlled, the rotating speed of the high-pressure air roller 13 can also be controlled to reach the optimal use state. The airflow of the tangential nozzle is discharged along the trend of the annular groove, and the air flow is effective, so that the air knife cannot be disturbed basically. Obviously, this embodiment can further simplify the structure and cost of the cover 1.
