Description
Technical Field
The invention relates to the technical field of road cleaning of environmental sanitation municipal machinery, in particular to road washing and sweeping equipment.
Background
Road washing and sweeping equipment is generally borne on a washing and sweeping vehicle, and the performance of the road washing and sweeping equipment directly influences the cleaning operation effect of the washing and sweeping vehicle. The road washing and sweeping equipment can realize road surface washing and sweeping, and pump and convey garbage into the garbage collection box, thereby achieving the purpose of cleaning the road surface.
The existing cleaning device of the washing and sweeping vehicle mainly comprises a left sweeping disc, a right sweeping disc, a left spray rod, a right spray rod, a middle spray rod and a suction nozzle. During operation, the left and right sweeping discs sweep the garbage (mainly large-sized garbage, such as branches, leaves, paper scraps, tobacco ends and the like) in the road surface areas on the two sides of the vehicle to the operation area in front of the suction nozzle, the spray boom cleans the garbage (mainly small-sized garbage, such as dust, sand particles, soil and the like) remained after the left and right sweeping discs are operated, and the cleaned sewage is collected and flows into the suction nozzle operation area. The middle spray rod cleans the road surface area at the bottom of the vehicle and drives sewage to the lower part of the suction nozzle. The suction nozzle sucks sewage generated after the operation of the left and right spray rods and the middle spray rod and other garbage in the operation area of the spray rods and conveys the sewage into the garbage collection box through the conveying pipeline.
However, the inventors have found that there still exist many defects in the prior art, specifically as follows:
1. the whole cleaning device requires a large arrangement space, needs two sets of motion mechanisms (a left sweeping disc, a right sweeping disc, a left spraying rod and a right spraying rod) to respectively realize cleaning and washing operation actions, and is relatively complex in structure, large in occupied space and not beneficial to equipment maintenance.
2. The sweeping of the left and right sweeping discs is required to have enough pre-pressure on the road surface, the sweeping is easy to wear, and the maintenance cost is high.
3. Is not suitable for operation at higher running speed, and the highest effective operation speed is generally 15 km/h. The main reasons for influencing the vehicle speed are: the operation speed is increased, the rotating speed of the left sweeping disc and the right sweeping disc is correspondingly increased, but the centrifugal force of the sweeping bristles is increased after the rotating speed is increased, so that the pre-pressure of the sweeping bristles and the ground is reduced, and even the sweeping bristles float off the road surface. In order to ensure good sweeping performance, the broom with pre-pressure has a certain contact length with the ground, which requires that the broom has certain flexibility. In order to overcome the influence of centrifugal force to maintain reasonable pre-pressure during high-speed rotation, the rigidity of the broom needs to be increased, so that the broom is contradictory to the requirement of certain flexibility of the broom. Clearly, sweeping requiring pre-compression is not suitable for higher speed operation.
4. After the left and right spray rods are cleaned, generated sewage is easy to gather together, a strand of sewage flows into the suction nozzle, and therefore the amount of the sewage in the suction nozzle is large, and the suction nozzle is not beneficial to sucking. After the operation, the position behind the left and right spray rod sewage flows can generate obvious residual pollution zones, and the overall cleaning operation effect of the road surface is seriously influenced.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Referring to fig. 1, there is shown a schematic top view of the road sweeping apparatus of the present embodiment, comprising: a first cleaning device 1, a second cleaning device 2, a third cleaning device 3, and a suction nozzle device 4; the first cleaning device 1 and the second cleaning device 2 are respectively positioned at two sides in front of the suction nozzle device 4 and used for driving the garbage at two sides of the suction nozzle device 4 to the working area of the suction nozzle device 4; the third cleaning device 3 is located behind the suction nozzle device 4, and is used for driving the garbage at the position of the suction nozzle device 4 to the working area of the suction nozzle device 4, that is, the cleaning area of the third cleaning device 3 is located between two ends of the suction nozzle device 4, the cleaning areas of the first cleaning device 1 and the second cleaning device 2 are located at the outer sides of two ends of the suction nozzle device 4, and the three areas have a certain overlapping area to avoid missing cleaning.
The first cleaning device 1 and the second cleaning device 2 have the same structure and cleaning principle, and rotationally clean the garbage to the front of the suction nozzle device 4 in a rotating manner, and the third cleaning device 3 is used for cleaning the garbage adhered to the ground, such as dust which cannot be sucked and picked up by the suction nozzle device 4, and washing the garbage to the working area of the suction nozzle device 4, and has the function of reducing dust.
The suction nozzle device 4 is used for sucking and picking up the garbage cleaned by the first cleaning device 1, the second cleaning device 2 and the third cleaning device 3 and pumping the garbage to a garbage bin on the road cleaning and sweeping equipment.
In order to save the arrangement space of the device, the first sweeping device 1 and the second sweeping device 2 each comprise a sweeping disk and a plurality of first spray rods 11 arranged on the sweeping disk. The first spray rod 11 is connected with a high-pressure water pipe, and can spray water, so that a water spraying device does not need to be arranged on the road washing and sweeping equipment independently. First spray lance 11 rotates along with the rotation of sweeping the dish to at rotatory in-process water spray washing ground, make after water spray pressure reached a definite value, rubbish that quality is little such as dust, sand grain, stone, leaf on can effectual clean the road surface of first spray lance spun water, play the effect of sweeping hair among the prior art. For the garbage which is difficult to be removed by water spraying and has large mass such as stones and bricks, the garbage is swept to the front of the suction nozzle device 4 by the sweeping bristles 13 on the sweeping disc in the rotating process.
Since the high pressure water sprayed by the first spray bar 11 can be used for cleaning small particle waste, the sweeping bristles 13 on the sweeping disk in this embodiment can be set in a state of critical contact with the ground (for example, a gap of 0-8mm is formed between the sweeping bristles 13 and the ground). When the sweeper is used, high-pressure water sprayed by the first spray rod 11 plays a main sweeping role, and the sweeping bristles 13 are in a critical contact state with the ground so as to assist sweeping. For example, when larger particles (having a size larger than the gap between the broom and the ground) exist on the ground and cannot be swept away by the high-pressure water, the particles are swept away by the broom 13. Because the high-pressure water is mainly used for cleaning, the abrasion consumption of the broom bristles 13 is greatly reduced, frequent replacement is not needed, and the use cost is saved.
Because the broom 13 basically has no requirement that pre-pressure is tightly attached to the road surface, the rigidity of the broom 13 can be designed to be larger, and the problem that the broom 13 floats up and is far away from the road surface due to centrifugal force at higher rotating speed can be avoided. Therefore, the first cleaning device 1 and the second cleaning device 2 are suitable for high-speed vehicle operation under the condition that the rotation speed of the sweeping disc is high.
Preferably, the cleaning area of the first cleaning device 1 is partially overlapped with the cleaning area of the third cleaning device 3; and/or the sweeping area of the second sweeping device 2 is partially overlapped with the sweeping area of the third sweeping device 3 to ensure the overall and thorough cleaning effect.

To facilitate and ensure effective cleaning, with continued reference to fig. 1, the third cleaning device 3 comprises a second spray bar on which a plurality of nozzles 31 are arranged, the spray areas of adjacent nozzles 31 partially overlapping, preferably a plurality of nozzles 31 being arranged at equal intervals. Among them, the second spray bar may be disposed in parallel to the width direction of the nozzle devices 4 (i.e., the left-right direction in fig. 1), and the nozzles 31 are disposed on the length portion of the second spray bar corresponding to the entire width of the nozzle devices 4.
Preferably, in order to provide better cleaning effect, referring to fig. 2, the sweeping areas of the first sweeping device 1 and the second sweeping device 2 are partially overlapped with the sweeping area of the third sweeping device 3, and the following conditions are satisfied:
0.5L≤D1≤L；
0.5L≤D2≤L；
wherein D1 is the overlapping width of the cleaning area of the first cleaning device 1 and the cleaning area of the third cleaning device 3; d2 is the overlapping width of the cleaning area of the second cleaning device 2 and the cleaning area of the third cleaning device 3; l is the width of the ejection area of each of the nozzles 31. The width of the cleaning area of the first cleaning device 1, the second cleaning device 2, and the third cleaning device 3 is the width of the area that can be covered by cleaning in the traveling direction, and for example, as shown in fig. 2, the width of the cleaning area of the third cleaning device 3 is the width between the leftmost side of the area that is swept by the leftmost nozzle 31 and the rightmost side of the area that is swept by the rightmost nozzle 31. The width of the ejection area of the nozzle 31 is the maximum width that can be covered in the left-right direction.
With reference to fig. 3 and 4, a schematic top view and a cross-sectional view of the first sweeping device 1 are shown, respectively; the following describes the structures of the first cleaning device 1 and the second cleaning device 2 with reference to fig. 3 and 4, where the first cleaning device 1 and the second cleaning device 2 are only installed at different positions, the first cleaning device 1 is installed in front of the left side of the suction nozzle device 4, and the second cleaning device 2 is installed in front of the right side of the suction nozzle device 4, and both are symmetrical with each other about the longitudinal center line of the road sweeping apparatus, and only the structural composition of the first cleaning device 1 is described below, and it should be understood that the structure of the second cleaning device 2 is understood with reference to the first cleaning device 1, and details are not repeated in this embodiment.
With continued reference to fig. 3 and 4, a plurality of the first spray bars 11 are disposed at equal angles around the central axis of the sweep disc, and the first spray bars 11 can rotate with the rotation of the sweep disc. Each first spray bar 11 has a corresponding nozzle 12, the high-pressure water jet formed by the nozzles 12 is fan-shaped, and the sweeping disc specifically comprises: the driving member 15 and the rotating body 142; the driving part 15 is used for driving the rotating body to rotate, the first spray bars 11 are arranged on the rotating body 142, sweeping bristles 13 can be further arranged in the sweeping disc according to actual working conditions and used for sweeping the road surface, the sweeping bristles 13 are only washed and swept by the spray nozzles 12 under the condition that the sweeping bristles 13 are not arranged, and the sweeping bristles 13 are arranged on the rotating body 142 under the condition that the sweeping bristles 13 are arranged, so that large-particle garbage can be cleaned in an auxiliary mode. Under the action of the rotating inertia force, sewage can be driven to the front of the suction nozzle device 4 in a relatively scattered state, so that the suction nozzle device 4 can suck and pick up the sewage, the problem of a residual pollution zone at the sewage gathering position is reduced or eliminated, and the overall cleaning operation effect is improved. In addition, the scouring action of the rotary jet water curtain can efficiently clean the road surface, and is particularly suitable for cleaning garbage (such as sludge, clay and the like) adhered to the road surface. Therefore, the rotary spraying mode can clean and decontaminate the dirty road edge powerfully. Among them, the driving member 15 is preferably a hydraulic motor.
In order to protect the bristles 13 and the first spray bar 11, the sweeping disk further comprises a sweeping disk cover 17, and the sweeping disk cover 17 is arranged on the driving part 15 and covers the rotating body 142, the first spray bar 11 and the rotary joint 14. In order to avoid the secondary pollution caused by the splashing of the garbage generated by the rotary spraying of the water curtain to wash the road surface, the sweeping disk cover 17 is adopted to prevent the splashing of the garbage. Furthermore, the rotation of the water curtain inside the pan cover 17 generates a strong air flow which is guided into the working area or the front of the working area of the suction nozzle arrangement 4 by the indentations designed in the pan cover 17 near the front of the suction nozzle. On the one hand, the air flow guides the splashed water mist, trash, etc. to the working area or front part of the working area of the nozzle device 4 so as to be sucked and picked up by the nozzle device 4. On the other hand, the airflow sucks the light flying objects such as leaves outside the tray cover 17 into the tray cover 17, and the light flying objects enter the operation area or the front part of the operation area of the suction nozzle device 4 along with the airflow so as to be sucked and picked up by the suction nozzle device 4. Therefore, the airflow generated in the sweeping disc cover 17 can be used for sucking light floating garbage such as leaves on the road surface, and is particularly used for cleaning the light floating garbage on the road edge. The sweeping disk cover 17 can also play a role in protection, and internal structures such as the first spray rod 11, the spray nozzles 12, the rotary joint 14 and the like in the sweeping disk cover can be prevented from being collided by obstacles on a road surface or a road edge.
The sweeping disc also comprises a water pipe 16 and a rotary joint 14, wherein the water pipe 16 is used for providing high-pressure water; a water flow distribution cavity 141 is arranged between the rotary joint 14 and the rotary body, and the rotary joint 14 is rotatably connected with the rotary body. The water pipe 16 communicates with the water flow distribution chamber 141 and with a portion of the first spray bar 11 located in a spraying area through the water flow distribution chamber 141 to deliver water to the portion of the first spray bar 11 and form a high pressure spray water curtain toward the ground. Referring to fig. 5, which is a schematic structural view of the rotary joint 14 and the rotary body, high-pressure water from the water pipe 16 enters the water distribution chamber 141, the water distribution chamber 141 distributes the high-pressure water to 3 first spray bars 11 for spraying and sweeping operations, the position of the water distribution chamber 141 is maintained during the rotation, and the first spray bars 11 alternately communicate with the water distribution chamber 141 during the rotation around the rotation center to perform the spraying and sweeping operations.
The rotary joint 14 may include an intermediate shaft and a jacket rotatably fitted around the outside of the intermediate shaft, the jacket may rotate around the intermediate shaft, the intermediate shaft has a water inlet, the jacket has a plurality of water outlets corresponding to the plurality of first spray bars 11, and each of the water outlets is intermittently communicated with the water inlet during rotation of the jacket.
Wherein the water inlet can be arranged at a proper position and is communicated with the water outlet through a corresponding proper structure. For example, the water inlet is provided on the top of the intermediate shaft, which includes a water tank communicating with the water inlet, the water tank being capable of communicating with at least a part of the plurality of water outlets at each moment of rotation of the jacket relative to the intermediate shaft, and only the first spray bar 11 rotated to communicate with the water tank is capable of spraying water, and the other first spray bars 11 do not spray water. By this arrangement, the water trough can be set in an appropriate orientation to correspond to the spray area.
For road cleaning work, such as a road cleaning vehicle, the working area is located at the outward positions of both sides of the road cleaning vehicle, and the garbage swept by the first sweeping device 1 and the second sweeping device 2 is gathered to the inward positions of both sides of the road cleaning vehicle, i.e. the front of the suction nozzle device 4, so as to be sucked by the suction nozzle device 4, for this purpose, the spraying area covered from the initial spraying boundary of the spraying water curtain to the final spraying boundary of the spraying water curtain is fan-shaped and located at the area of the sweeping plate facing the front side, referring to fig. 2, the angle of the fan-shaped is θ, the angle between the initial spraying boundary of the spraying water curtain and the left and right horizontal directions is α, the angle between the final spraying boundary of the spraying water curtain and the left and right horizontal directions is β,
wherein α is more than or equal to 5 degrees, and β is more than or equal to 5 degrees.
It is apparent that α + β + θ is 180 ° in the present embodiment.
When α is larger than or equal to 5 degrees, the water sprayed by the first spray rod 11 can not rush to the left side of the first cleaning device 1 (the area suction nozzle device 4 can not suck), and the same effect can be achieved when β is larger than or equal to 5 degrees.
Further, in order to facilitate control of the first cleaning device 1 and the second cleaning device 2, each of the first cleaning device 1 and the second cleaning device 2 further includes: a mounting frame 19 and a lifting mechanism 18, wherein the mounting frame 19 is connected with the lifting mechanism 18, and the lifting mechanism 18 is connected with the sweeping disk.
