[0002] Municipal road cleaning devices are usually a combination of a cleaning device and a mobile device. A common example is a road sweeper. A road sweeper is a new type of efficient cleaning equipment that integrates road cleaning, garbage collection and transportation. It is a sweeper vehicle with a road cleaning function modified on a special vehicle chassis. In the prior art, when the garbage is sticky or the road surface is wet and has an adsorption effect on the garbage, it is difficult to quickly clean and recycle the garbage, resulting in a decrease in cleaning efficiency.

It has the function of unmanned obstacle clearing, can automatically crush cement blocks, and automatically hook obstacles from the expansion joints of bridges. Through the variable-diameter cleaning device, more garbage can be taken out, and the construction steps can be optimized at any time, providing more efficient and intelligent services. Although this patent solves the above problems, it is still difficult to clean up sticky garbage. Therefore, an automatic intelligent cleaning device for municipal roads is proposed to solve the above problems. Summary of the invention

In the process of the brush scrapers approaching each other, the friction between the brush scrapers and the ground continues to increase. The friction causes the brush scrapers and the cross-shaped slider to slide closer to the side of the intelligent cleaning vehicle in the cross-slot guide rail, and then drives the sliding material receiving plate to slide closer to the side of the intelligent cleaning vehicle on the inner surface of the scraper shovel. At this time, the sliding material receiving plate drives the resistance plate to approach the rotating plate. When the resistance plate contacts the rotating plate, it drives the rotating plate and the rotating shaft to rotate. Then the sliding material receiving plate continues to slide to drive the garbage to the bottom of the fixed baffle. When the brush scraper leaves the ground, the cross-shaped slider slides to the bottom of the cross-slot guide rail under the influence of gravity, and at the same time drives the sliding material receiving plate and the resistance plate away from the rotating plate.At this time, the rotating plate rotates under the influence of gravity to block the garbage, so that the garbage stays under the fixed baffle, and the induced draft fan between the bellows and the suction hose is started, and the suction hose sucks the garbage in the scraper shovel into the bellows.

The scraper shovels 7 are close to each other to clamp and scoop up the garbage, making it easier to clean up the sticky garbage, thereby improving the cleaning effect of the device. When the scrapers 74 are close to each other, the sticky residues of the sticky garbage left on the ground are scraped off, further improving the cleaning effect. The inner side of the intelligent cleaning vehicle 1 is provided with a cleaning material cutting device 8 for chopping up large garbage, which is convenient for the device to continuously collect road garbage. The inner side of the intelligent cleaning vehicle 1 is provided with a debris collecting device 9 for discharging the chopped garbage, which is convenient for recycling recyclable materials and improving the environmental protection effect of the device. A through groove is provided on the inner side of the bottom of the scraper shovel 7, and the inner surface of the through groove is in contact with the front and rear sides of the top of the cross-shaped slider 73.

When the resistance rod 910 descends, the sliding plate 97 slides downward under the influence of gravity, thereby causing the sliding plate 97 to slide back and forth up and down. The sliding plate 97 then drives the second scraper ring 98 to slide back and forth on the inner wall of the cutting barrel 82 and scrape off the garbage debris, so that the device can move back and forth up and down while rotating, and scrape off the debris in multiple directions, further improving the scraping efficiency.

[0018] The present invention provides an automatic intelligent cleaning device for municipal roads. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
