Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

1 to 3, the utility model includes a cart 1, a push rod 2 hinged in the left and right directions on the cart 1; a housing 3 with an opening facing downward is fixed on the left end of the push rod 2; A rotating shaft 4 is installed in the direction; brushes 5 are evenly distributed on the rotating shaft 4; an impeller 6 is fixedly sleeved in the middle of the rotating shaft 4; 4. Rotate clockwise; a dust cover 8 is installed on the upper left of the housing 3, and the dust cover 8 communicates with the interior of the housing 3; the top of the dust cover 8 is provided with a removable filter 9.

In order to realize the ejection of high-pressure gas from the spray head 7 , an air pump 10 is installed on the cart 1 , and the air pump 10 is communicated with the spray head 7 through a pipeline.

In order to facilitate pushing the push rod 2, a vertical rod is installed on the left end of the cart 1, and the middle part of the push rod 2 is hinged with the upper end of the vertical rod.

In order to better remove the dust and gravel on the brush 5, the casing 3 is provided with a vertical baffle 11 located directly above the rotating shaft 4, and the baffle 11 is placed in the front and rear directions; the lower end of the baffle 11 can block the brush 5.

In order to realize the disassembly of the filter screen 9, the filter screen 9 is fixed with the dust cover 8 by bolts.

In order to better collect sundries, a vertical flexible board 12 is installed on the front side of the casing 3, and the flexible board 12 is made of leather or plastic.

When the utility model is used, the air pump 10 is first started, and the high-pressure gas will be ejected from the nozzle 7 at this time, and since the nozzle 7 corresponds to the impeller 6, the airflow will push the rotating shaft 4 to rotate, and then the brush 5 on the rotating shaft 4 will follow Rotate together. In specific use, push the cart 1 to the crack of the road surface, and then make the middle of the entire shell 3, that is, the position of the nozzle 7, correspond to the position of the crack, so that the high-pressure air blows the shaft 4 to rotate, and the other side The cracks can be blown directly, so that the gravel, sundries and dust in the cracks are blown away.

At the same time, while the rotating shaft 4 is rotating, the brush 5 on the rotating shaft 4 will also clean the road surface. Since the rotating shaft 4 has a certain length, the brush 5 can also clean the road surface on both sides of the crack; it is beneficial to the subsequent construction of asphalt .

Since the airflow is blown to the left and the rotating shaft 4 is also rotated clockwise, the gravel, debris and dust after being blown by the airflow and brushed by the brush 5 will move to the left and follow the flexible board 12 and the casing. 3. Enter the interior of the dust cover 8; at the same time, because the top of the dust cover 8 is provided with a filter screen 9, under the blocking action of the filter screen 9, the sundries will be blocked in the interior of the dust cover 8, while containing A small amount of dust gas will diffuse outward from the filter screen 9 .

Through the filtration of the filter screen 9, the dust will be greatly reduced, and the diffusion speed of the dust will also be greatly reduced, so that the dust can be better suppressed, which is conducive to reducing air pollution.

After using for a period of time, the filter screen 9 can be opened, and the gravel and other loads inside the dust cover 8 can be cleaned out, and the filter screen 9 can be cleaned at the same time; it can be used repeatedly.

By raising the right end of the push rod, the friction force between the brush and the ground can be increased, so that the brush can adjust the force of the brush on the ground, and realize the cleaning of various sundries.

On the one hand, the device uses high-pressure airflow to clean the cracks, and on the other hand, it also uses the high-pressure airflow as the driving force for the rotation of the rotating shaft 4. The brushes 5 are evenly distributed outside the rotating shaft 4 to form brush rollers, so that the brushes 5 can adhere to the inside of the cracks. The debris on both sides of the crack and the pavement on both sides of the crack can be cleaned; it can make the debris that is inconvenient to be blown off easier to be cleaned; at the same time, the pavement within a certain width on both sides of the crack can be cleaned; it is beneficial to the subsequent crack filling operation.

By arranging the dust cover 8 on the upper left of the casing 3, the device utilizes the rotation direction of the rotating shaft 4 and the purging direction of the air flow, so that the sundries can automatically enter the interior of the dust cover 8 and pass through the flexible board. 12. Avoid a large amount of debris from flowing out from the gap between the left side of the shell 3 and the ground; the collection of debris is achieved as much as possible; at the same time, under the action of the filter screen 9, it can also play a role in dust prevention .

The utility model is easy to operate, ingenious in structure, low in cost, convenient in manufacture, safe and effective, greatly improves the portability of crack cleaning, is beneficial to realize all-round cleaning, and can realize the collection of sundries and the treatment of dust.
