Description

Technical Field

[0001] The present application relates to the technical field of road sweeping, and in particular to a back-blowing dust collection device for a road sweeper. Background Art

[0002] The road sweepers currently on the market cannot clean the road surface when their operating speed exceeds 20km / h. In the existing technology, the operating width of the road sweeper is about 3 meters. Since the installed power limits the power of the adsorption fan, in order to ensure the adsorption effect, the diameter of the suction cup adsorption tube of the road sweeper is more than 120mm, and the sum of the cross-sectional areas of all adsorption tubes on the road sweeper shall not be greater than half of the cross-sectional area of the suction port of the adsorption fan. As a result, the number of adsorption tubes on the road sweeper is small, which increases the distance that garbage and foreign matter on the road surface need to be gathered to the suction port. In order to improve the cleanliness, the power of the adsorption fan and the blowing fan can only be increased, which will not only reduce the operating speed and increase the fuel consumption during operation, but also reduce the operating distance, which does not meet the existing energy conservation and emission reduction needs.

DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail in conjunction with the embodiments and drawings. Here, the illustrative embodiments of this application and their descriptions are used to explain this application, but are not intended to limit this application.

[0060] In order to improve the operating speed and road cleanliness, the existing road sweepers with back-blowing systems on the market mostly use full-section back-blowing or multi-section back-blowing dust collecting suction cups. Even if the back-blowing air volume and air pressure of the back-blowing machine can be adjusted according to the operating speed of the road sweeper, when the dust, garbage and foreign objects are unevenly distributed on the road or even concentrated in one point or position, the back-blowing will not be able to blow cleanly and there will be blind corners.

[0061] The existing suction cups with back-blowing air outlets on the market connect the air outlet of the back-blowing blower to the air blowing interface of the back-blowing suction cup through a hose, so that the back-blowing air is blown to the ground. There is a lack of guidance for the back-blowing air, resulting in the back-blowing air only lifting the dust inside the suction cup. The dust close to the suction port will be sucked away, while the dust far from the suction port will be blown outside the suction cup to cause secondary dust. At the same time, large particles of garbage and foreign matter cannot be blown away. Since the back-blowing port of the suction cup is far away from the ground, not only does it fail to form an effective back-blowing effect, but it also increases energy consumption.

[0062] In order to increase the operating speed while ensuring the cleanliness of the road surface, existing road sweepers can only increase the power of the back-blowing machine, increase the air outlet of the back-blowing machine, increase energy consumption, and reduce the operating range.

[0063] The sweeping disc of the existing road sweeper collects, gathers and absorbs dust, garbage and foreign objects on the road into a suction cup, which increases the manufacturing and subsequent maintenance costs.

[0064] In summary, reference Figures 1 to 21 ,like Figure 1As shown, this embodiment provides a back-blowing dust collecting device for a sweeper. Through automatic control, it can automatically adjust the air volume and pressure of the back-blowing blower and the position and angle of the back-blowing air outlet according to the operating speed and unpredictable dust and garbage conditions on the road surface during the operation of the sweeper, so that the road surface cleanliness can be maintained when the vehicle's operating speed is above 30km / h. In addition, there is no need to increase the power of the back-blowing blower and the back-blowing air outlet, so that the vehicle also has a better effect in terms of energy consumption. The back-blowing dust collecting device for the sweeper includes a dust collecting device cover 006, a visual scanner 100, a pair of wind nozzle rotating and translating mechanisms 200 and a pair of side wind nozzle rotating mechanisms 300.

[0090] Preferably, Example 2 is a specific structural description of the adsorption pipe in Example 1.

[0091] Preferably, the suction port shell 500 is installed at the rear end of the dust collecting device cover 006 and is about 10 mm away from the road surface. The side air outlet 303 and the air outlet 210 blow up the garbage, dust and debris covered by the back-blowing dust collecting device through the back-blowing air and gather them at the dust suction port position of the suction port shell 500. Garbage and foreign matter higher than 10 mm will be scooped up by the dust suction port of the suction port shell 500, and are adsorbed to the dust collection box of the sweeper through the adsorption tube 504 by the adsorption air flow with a wind speed higher than 90 m / s. The suction port shell 500 and the annular back-blowing nozzle molding 501 form an annular back-blowing nozzle with a width of 2 mm. The annular back-blowing nozzle can blow out an annular back-blowing air flow with a wind speed higher than 90 m / s, which can blow away the garbage, dust and gravel lower than 10 mm and that have not been shoveled away from the road surface, and then be adsorbed to the dust collection box of the sweeper through the adsorption tube 504 by the adsorbed air flow.

[0092] Working principle: When sweeping, the back-blowing dust collecting device is placed on the ground 1 through the lifting mechanism, and the wheels 001 are supported on the ground, so that the distance between a pair of side rubber plates 004, the front rubber plate 005, the middle isolation rubber plate 008 and the suction port shell 500 and the ground 1 is about 10 mm. The back-blowing blower is started, and the rotation speed of the back-blowing blower is adjusted according to the operating speed of the sweeper. The air outlet of the back-blowing blower provides back-blowing air to the translation air inlet pipe 209, the side air inlet pipe 302 and the suction port air duct 503 through the hose. At the same time, the back-blowing dust collecting device is pulled to move with the sweeper. After the visual scanner 100 is powered on, it scans the road surface, collects the distance between the road surface and the visual scanner 100, the volume of dust and debris on the road surface and its distribution on the road surface, and then turns it The controller 102 converts the air volume and pressure of the back-blowing machine into a specific analog signal and transmits it to the controller 102. The controller 102 controls the air volume and pressure of the back-blowing machine according to the road surface information collected by the visual scanner 100 and the operating speed of the sweeper. At the same time, the controller 102 directly controls the translation motor 206, the rotation motor 207 and the side nozzle rotation motor 305 through the electrical signal, so that the controller 102 can make adjustments according to the changes of garbage and debris on the road surface by adjusting the blowing position and angle of the air outlet nozzle 210 and controlling the blowing angle of the side air outlet nozzle 303, so as to gather the dust and debris on the road surface, so that under the action of the suction fan of the sweeper, the garbage and foreign matter can be adsorbed into the dust collection box of the sweeper through the adsorption tube 504, thereby improving the operating speed and reducing the operating energy consumption while ensuring the cleanliness of the road surface.

[0093] When the translation motor 206 receives the movement signal from the controller 102, the translation motor 206 drives the translation gear 212 to rotate, and the translation gear 212 engages with the rack 208. The rack 208 is fixed to the rotating translation bracket 201. The translation motor 206 is installed on the mobile bracket 203, so it drives the mobile bracket 203 to slide on the chrome-plated rod 205. Several translation motors 206 work at the same time, so that several mobile brackets 203 move at the same time, and the rotating motor 207 and the air outlet nozzle 210 are connected to the mobile bracket 203, so that the air outlet nozzle 210 and the rotating motor 207 can move with it, so that the blowing position of the air outlet nozzle 210 can be controlled by the movement of the air outlet nozzle 210.

[0094] When the rotating motor 207 receives the rotation signal from the controller 102, the rotating motor 207 drives the rotating gear 214 to rotate, the rotating gear 214 meshes with the rotating intermediate gear 215, and the rotating intermediate gear 215 meshes with the rotating tube gear 216. The rotating gear 214 drives the rotating tube gear 216 to rotate. The air outlet nozzle 210 is installed on the rotating tube gear 216. Therefore, the air outlet nozzle 210 rotates with the rotating tube gear 216, so that the air outlet direction of the air outlet nozzle 210 can be adjusted. The translational air inlet pipe 209 is connected to the air outlet of the back-blowing device, so that back-blowing can be provided.

[0095] When the side air nozzle rotating motor 305 receives the rotation signal from the controller 102, the side air nozzle rotating motor 305 drives the rotating gear 214 to rotate, the rotating gear 214 engages with the rotating intermediate gear 215, the rotating intermediate gear 215 engages with the rotating tube gear 216, and the rotating gear 214 drives the rotating tube gear 216 to rotate. The side air outlet nozzle 303 is installed on the rotating tube gear 216, so under the drive of the rotating tube gear 216, the side air outlet nozzle 303 will follow the rotating tube gear 216 to rotate to adjust the air outlet direction of the side air outlet nozzle 303, and the side air inlet pipe 302 is connected to the air outlet of the back-blowing machine, so that the side air outlet nozzle 303 can provide back-blowing air.
