The embodiment can adopt a system model as shown in fig. 14, a vacuum pump 55 is installed at the top of a closed garbage cache box 54, an exhaust pipe of the vacuum pump 55 extends into the closed garbage cache box 54, a filter cover 56 is arranged at the orifice of the exhaust pipe, the upper end of the closed garbage cache box 54 is led out of an exhaust channel 32 and then is connected with the top of a cover body 1, a periodic garbage discharge port 57 arranged at the bottom of the closed garbage cache box 54 is usually closed, and when the garbage storage capacity in the closed garbage cache box 54 reaches a certain degree, the periodic garbage discharge port 57 is opened to discharge garbage into a garbage can in a vehicle or a garbage can outside the vehicle.

Compared with the traditional grounded rotary brush type air suction cover, the invention requires that the cleaning unit in the air suction cover cannot contact with the ground, so that the shock-absorbing support wheel assemblies are respectively arranged at the left side and the right side of the front end and the left side and the right side of the rear end of the cover body 1, and the cover body 1 can independently walk on the ground. Moreover, can keep each shock attenuation supporting wheel subassembly to support cover body 1 after, bottom opening keeps interval d with ground, interval d is adjustable moreover, reaches moderate gas blocking effect, when the air current inner loop is realized by the air knife exhaust in the cover body 1 and the pipeline of bleeding, external air current can get into in the induced draft cover from interval d and carry out the atmospheric pressure compensation, is favorable to preventing the dust and leaks. The bottom of the cover body 1 can be provided with a layer of annular rubber ring 53 for protecting the edge of the cover body 1 when the jolt degree is large, so that the edge of the cover body 1 is prevented from being collided and deformed, and the gas blocking effect is affected.

As can be seen from fig. 1 and 2, each shock-absorbing support wheel assembly comprises a support 2 fixed on the outer side wall of the cover body 1, a sleeve 5 is vertically fixed on the support 2, a screw is sleeved in the sleeve 5, and the screw can slide in the sleeve 5. But the screw is provided with a height adjusting nut 6 at the upper end and the lower end of the sleeve 5, respectively, and the screw is fixed on the sleeve 5 through the adjusting nut. And a shock absorber 4 is arranged at the bottom of the screw rod, and the bottom of the shock absorber 4 is connected with the travelling wheel 3. Thus, each shock-absorbing support wheel assembly is capable of providing a shock-absorbing function when the cleaner is towed forward.

This embodiment employs a traction structure as shown in fig. 1 and 2. The cover 1 is not fixed directly under the vehicle body, but a traction seat 7 is fixed at the front end of the cover 1 and is connected with the traction part of the vehicle. Further, the present embodiment is provided with a traversing adjusting mechanism for driving the fifth wheel 7 to traverse. As shown in fig. 10, in one form of the traversing adjusting mechanism, shaft holes are arranged on two side walls of the traction seat 7 and a long shaft 9 is arranged, a sleeve 36 is sleeved outside the long shaft 9, and the traction rod 8 is vertically and fixedly connected with the sleeve 36. A baffle 37 is fixed on one side of the sleeve 36, a clamping seat 33 is arranged at one end in the traction seat 7 and is used for clamping the inherent electric push rod 34, and a push rod part 35 of the electric push rod 34 is propped against one side of the baffle 37. A spring 38 is sleeved on one end of the long shaft 9 far away from the electric push rod 34, and the spring 38 is supported between the sleeve 36 and the side wall of the traction seat 7. Thus, when the control electric push rod 34 is extended, the sleeve 36 can be pushed to move, that is, the retaining cover 1 moves transversely relative to the traction rod 8, and when the control electric push rod is contracted, the cover 1 can be controlled to move transversely in the opposite direction. The purpose of setting up sideslip adjustment mechanism to the cover body 1 of this embodiment is to prevent to inhale and clean the vehicle when moving to highway left side or right side, and vibration-damping support wheelset around the cover body 1 rolls easily at the vibration marking (punctiform protruding sideline or punctiform sunken sideline, because the walking wheel 3 of the cover body 1 is less, runs for a long time and can damage each inside important part very fast to the vibration marking can appear high-frequency vibration). The electric push rod 34 is controlled through the cab, so that the transverse adjustability of the cover body 1 can be controlled through the transverse movement adjusting mechanism, damage to the cover body is avoided, and the service life of the cover body is prolonged.

The traversing adjusting mechanism can also have other forms, for example, when the traversing function of the cover body 1 is ensured and the basic structure is controlled, a stepping motor can be used for replacing the electric push rod 34, a rotating shaft of the stepping motor is connected with a screw rod, a baffle plate platform is provided with a screw hole, the screw rod is in threaded connection with the screw hole, and the stepping motor can drive the baffle plate 37 to further drive the sleeve to axially move after rotating. And can also be realized by adopting an electromagnetic telescopic rod mode, which is not described in detail.

As shown in fig. 2, a rotary air knife mechanism for road surface cleaning is mounted at the rear end inside the cover body 1, and the rotary air knife mechanism comprises a high-pressure air roller 13, a semi-closed arc cover 11, a fixed seat 12, a rotary sleeve 22, a driving mechanism and the like.

As shown in fig. 14, the outlet of the high-pressure pump 58 located in the vehicle cabin is communicated with the hollow cavity 27 of the high-pressure air roller 13 of the rotary air knife mechanism through the high-pressure air pipe 23. The semi-closed arc cover is matched and sleeved on the outer side of the high-pressure air roller, but one side of the semi-closed arc cover 11 is provided with an opening in parallel along the axial direction as a fan outlet surface 65, and an arc-shaped sealing layer is arranged between the semi-closed arc cover 11 and the high-pressure air roller and used for sealing all the high-pressure spray heads 15 entering the inner side of the semi-closed arc cover 11 (when the high-pressure spray heads are not in a housing, all the radial holes are directly sealed).

As shown in fig. 3-6, a plurality of air knife edges are uniformly distributed on the side surface of the high-pressure air roller 13 along the circumferential direction, each air knife edge is parallel to the axial direction, and in this embodiment, each air knife edge is composed of a plurality of uniformly distributed high-pressure spray heads 15 as shown in fig. 5 and 6 (the high-pressure spray heads 15 are larger than the actual pictures in order to show the structure). As can be seen from fig. 5 and 6, radial holes 14 are bored in the circumferential side wall of the high-pressure air roller 13 in the radial direction as mounting holes for fitting the corresponding high-pressure jet heads 15. Because the high-pressure spray heads 15 of each air knife are arranged along a straight line, an air knife blowing surface 48 and an air knife reflecting surface 49 are formed after high-pressure air spraying is carried out simultaneously, as shown in fig. 9, along with the clockwise rotation of the high-pressure air roller 13, each air knife rotates from bottom to top in sequence, high-pressure air can contact with the ground to form the air knife reflecting surface 49 when the air knives are at a small angle, the ground attachment can be scooped up, along with the high-speed rotation of the high-pressure air roller 13, the air knife blowing surface 48 moves upwards rapidly, so that the cleaning object is lifted up, the first air knife blowing surface 48 lifts up the cleaning object, and then the second air knife blowing surface and the third air knife blowing surface 48 sequentially follow up the cleaning object continuously, push the cleaning object to be sucked away near the exhaust pipe mouth, and achieve the transmission from high-pressure air blowing to exhaust. Further, the arc-shaped guide plate 67 shown in fig. 15 is internally installed at the front side in the cover body 1, the baffle plate 68 is obliquely installed at the rear side of the air suction channel 32, and cleaning objects can be quickly lifted to the suction port by utilizing the arc-shaped guide plate 67 and the baffle plate 68, so that the use effect and the cleaning efficiency are improved. The suction channel can also be extended into the cover 1 to reduce the suction opening height.

As can be seen from fig. 3 and 4, the semi-closed arc-shaped cover 11 is matched and arranged on the outer side of the high-pressure air roller 13, as can be seen from fig. 5, the two ends of the high-pressure air roller 13 are arranged in bearing seats through end bearings 19, the bearing seats are arranged in shaft holes of end plates (an end plate one 17 and an end plate two 18) on the two sides of the semi-closed arc-shaped cover 11, and the semi-closed arc-shaped cover 11 is arranged on the fixed seat 12.

As shown in fig. 3 and fig. 4, an opening is formed in parallel on one side of the semi-closed arc cover 11 along the axial direction to serve as an air outlet surface 65, so that three groups of air knife edges are located in the fan surface area at the same time, that is, no matter how the high-pressure air roller 13 rotates, three groups of air knife edges are located in the air outlet surface 65 all the time to serve as an air outlet unit. The wind knife edge in the semi-closed arc cover 11 is blocked by the semi-closed arc cover 11 and cannot exhaust wind, so that the wind knife edge serves as a wind-avoiding unit.

As shown in fig. 5 or 7, one end wall center of the high-pressure air roller 13 is connected with a hollow rotating shaft 20, the tail end of the hollow rotating shaft 20 extends to form an air outlet shaft 26, the air outlet shaft 26 is hermetically sleeved in a rotating sleeve 22 through an inner bearing 24 and a sealing ring 25, a high-pressure air pipe 23 is communicated in the rotating sleeve 22 and is communicated with a cavity of the hollow rotating shaft 20, the other end wall center of the high-pressure air roller 13 is connected with a solid rotating shaft 21, 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 the axial direction of the high-pressure air roller.

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

The function that can be achieved in this embodiment is 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 face 65, and each air knife moves from bottom to top rapidly, and the front slave continuously circulates, so that the ground attachment can be effectively scooped up and lifted to the vicinity of the suction port, and the cleaning speed is fast, and the efficiency is high. The traditional cleaning mode by contacting the rotary brush head 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 cover has a series of problems of lower cleaning efficiency, abrasion blocks and the like. The embodiment is suitable for the expressway to be used for cleaning rapidly, provides cleaning equipment for the expressway ground, and has obvious cleaning efficiency and effect due to the common brush head type cleaning vehicle when the cleaner is used for common streets. It can be seen that, in this embodiment, the air knife and the air draft channel inside the hood body 1 realize the internal circulation of the air draft hood, and a smaller distance d exists between the hood body 1 and the ground, so that air pressure compensation can be realized, and the environment protection performance is very strong, and whether water is sprayed or not can not cause dust pollution, so that the normal use of the air draft hood is ensured all the time.

Example 2: the second high-pressure air-roll type suction hood for cleaning the expressway aims at the structure of the area of the air outlet fan face 65 formed between the semi-closed arc hood 11 and the high-pressure air roll 13 in the embodiment 1, and the direction angle of the area of the air outlet fan face 65 can be adjusted based on the embodiment 1. Namely, the moderate rotation of the semi-closed arc cover 11 can be controlled to control the orientation angle of the sector area, so that the optimal 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 fig. 4, the fixing base 12 is used for matching and clamping the semi-closed arc cover 11, a screw hole is vertically arranged on the fixing base 12, a jackscrew 64 is installed on the fixing base 12, the jackscrew 64 is used for tightly jacking and connecting the semi-closed arc cover 11, the fixing base 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 high-pressure air roller type air suction cover for cleaning the expressway is different in driving mechanism on the basis of embodiment 1, the embodiment gives up to use a transmission mode such as a motor, a gear or a belt pulley and the like, and utilizes high-pressure air flow as the driving mechanism, specifically, annular grooves are circumferentially distributed on the side surface of the high-pressure air roller 13 to serve as ventilation grooves, tangential holes are tangentially formed in the ventilation grooves, tangential spray heads are arranged in the tangential holes, and the air knife edges are isolated by the ventilation grooves or are alternately distributed with the ventilation grooves. Unlike the air knife formed by combining the high-pressure jet 15 described in embodiment 1, the high-pressure jet 15 is perpendicular to the inner wall of the semi-closed arc cover 11 in the radial direction (normal line), that is, the air flow direction, so that the high-pressure air roller 13 is not brought with rotational power. However, in this embodiment, the tangential nozzle can blow the air flow in the direction close to the tangential direction against the inner wall of the semi-closed arc-shaped cover 11, and the air flow is discharged from the annular groove, so as to realize continuous tangential air flow, so that the continuous tangential air flow can cause the high-pressure air roller 13 to rotate under the reaction when the continuous tangential air flow can blow against the semi-closed arc-shaped cover 11, thereby achieving the purpose of driving the high-pressure air roller 13 to rotate. The rotation speed of the high-pressure air roller 13 is influenced by the high-pressure degree and the air quantity sprayed by the tangential spray head, and after the air quantity sprayed by the tangential spray head is controlled, the rotation speed of the high-pressure air roller 13 can be controlled to reach the optimal use state. The air flow of the tangential spray head is discharged along the trend of the annular groove, and the air flow is effective, so that the air knife is not disturbed basically. Obviously, this embodiment can further simplify the structure and cost of the cover 1.

Example 4: the fourth high-pressure air roller type air suction cover for cleaning the expressway adopts the air knife mode shown in fig. 7 and 8 on the basis of the embodiment 1, namely a plurality of air knives uniformly distributed on the circumferential side wall of the high-pressure air roller 13, namely a plurality of prolate high-pressure air slits 28 along the bus respectively, and the high-pressure air flow discharged from the high-pressure air slits 28 is easier to form the air knives.

Example 5: the utility model provides an adjustable cover that induced drafts of angle for highway cleans, includes lower extreme open-ended cover body 1 and exhaust system, and this embodiment induced drafts the cover and can use with current garbage sweeper that contains exhaust system combination, after using this embodiment to induced drafted the cover and replace current induced drafted the cover of taking rotatory brush head, can drive the required result of use of this embodiment.

The exhaust system of the existing garbage sweeper is usually arranged in a carriage, and an exhaust channel 32 of the exhaust system is arranged at the top of the cover body 1.

In this embodiment, shock-absorbing supporting wheel assemblies are respectively mounted on the left and right sides of the front end and the left and right sides of the rear end of the cover body 1, so that the cover body 1 can independently walk on the ground.
