Description

Technical Field

[0001] The present invention belongs to the technical field of transportation engineering, and particularly relates to a road cleaning device for transportation engineering and a cleaning method thereof. Background Art

[0002] With the development of society, more and more attention is paid to the environment. After a period of time, a large amount of dust and dirt will remain on the road surface of transportation engineering, which needs to be cleaned. Generally, a road cleaning device will be used during the cleaning process.

[0003] The existing road cleaning devices have the following disadvantages in actual use: 1. When the cleaning device is in use, the spraying and cleaning effect on the road surface is relatively poor. Since there is a lot of dust on the road surface, simply spraying water cannot effectively clean the road dust;

[0004] 2. When the cleaning device is in use, although it can sweep the road surface, the existing sweeping device only has one cleaning broom, and the sweeping effect on the road dust is relatively poor. If multiple groups of motors are used to drive multiple groups of brooms for sweeping, the use cost is relatively high;

[0005] 3. Before the sweeping device is used, some dust remains in the road surface gaps, and the dust in the gaps cannot be cleaned out only by the broom. Therefore, the cleaning effect on the road surface is relatively poor. Summary of the Invention

[0017] Further, a cleaning method for a road surface cleaning device for transportation engineering includes the following steps:

[0018] S1: When blowing and cleaning the road surface, first turn on the fourth driving motor. The fourth driving motor drives the second rotating rod to rotate through the output end. The rotation of the second rotating rod drives the driving gear to rotate. The rotation of the driving gear drives the transmission gear to rotate. The rotation of the transmission gear drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the hollow pipe to rotate. The rotation of the hollow pipe can drive the angle of the jet pipe to be adjusted to an appropriate position. Then turn on the vacuum air pump. The vacuum air pump will generate a large amount of air flow. The air flow follows the connecting pipe and the hollow pipe and finally sprays out through the jet pipe, thereby blowing and cleaning the road surface.

[0019] S2: When cleaning the road surface, first turn on the second driving motor. The second driving motor drives the threaded rod to rotate through the output end. The rotation of the threaded rod drives the nut block to descend. The descent of the nut block drives the lifting plate to descend. The descent of the lifting plate can drive the cleaning broom to contact the ground. When the lifting plate moves up and down, it will drive the slider to slide on the surface of the sliding rod, thereby improving the stability of the lifting plate during the lifting and lowering process. At the same time, turn on the third driving motor at the upper end of the installation box three. The third driving motor drives the first gear to rotate through the output end. The rotation of the first gear drives the synchronous belt to rotate. The rotation of the synchronous belt drives the second gear to rotate. The rotation of the first gear and the second gear drives the first rotating rod to rotate. The rotation of the first rotating rod can drive the cleaning broom to perform large-area cleaning of the road surface;

[0020] S3: When spraying the road surface, pour water into the water tank through the water inlet hopper, and then pour the dust suppressant into the water tank through the feed hopper. Turn on the first driving motor on the side of the installation box two. The first driving motor drives the driving gear to rotate through the output end. The rotation of the driving gear drives the driven gear to rotate. The rotation of the driven gear drives the stirring shaft to rotate. The rotation of the stirring shaft drives the stirring rod to fully mix the water and the dust suppressant in the water tank. After mixing, turn on the water pump. The water pump pumps out the spraying liquid through the liquid extraction pipe and sends it into the interior of the spraying plate through the liquid discharge pipe, and finally sprays it on the road surface through the spray head, thereby cleaning the road surface, and the setting of the dust suppressant can effectively reduce the problem of dust.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention is provided with an air pump blowing and cleaning mechanism. The vacuum air pump can generate a strong air flow, which can quickly blow away dust, debris and other sundries on the ground. The cleaning efficiency is high, and the cleaning time can be significantly shortened. Secondly, the dirt existing in the road surface gaps cannot be effectively cleaned only by the broom, and the air flow generated by the vacuum air pump can blow out the dirt from the gaps, thereby improving the cleaning effect on the road surface.

[0023] 2. The present invention is provided with a road surface cleaning mechanism. This mechanism can control the height of the cleaning broom from the ground, and clean some larger dirt and gravel on the road surface by rotating the cleaning broom, thereby further improving the cleaning effect on the road surface. At the same time, the brush head of the cleaning broom rotates at a fixed speed, which can evenly clean the road surface and avoid omission or repeated cleaning that may occur during manual cleaning.

[0024] 3. The present invention is provided with a road surface spraying mechanism. By adding a dust suppressant to the spraying water, the dust suppressant can reduce the surface tension of the water, make the water droplets more likely to combine with the dust particles, thereby enhancing the wetting and agglomeration effects and effectively suppressing dust. Secondly, the dust suppressant is applicable to a variety of environmental conditions, including dry climate and low temperature environment, and will not cause the road surface to freeze due to temperature changes, affecting traffic safety.
