Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises a cart 1, a push rod 2 hinged on the cart 1 in left and right direction; a shell 3 with a downward opening is fixed at the left end of the push rod 2; a rotatable rotating shaft 4 is arranged in the shell 3 in the front-back direction; the rotating shaft 4 is uniformly provided with brushes 5; the middle part of the rotating shaft 4 is fixedly sleeved with an impeller 6; a spray head 7 which is inclined downwards is arranged on the shell 3; the high-pressure airflow passing through the spray head 7 can push the rotating shaft 4 to rotate clockwise; a dust cover 8 is arranged at the left upper part of the shell 3, and the dust cover 8 is communicated with the inside of the shell 3; the top of the dust cover 8 is provided with a detachable filter screen 9.

In order to realize the high-pressure gas spraying from the spray head 7, an air pump 10 is mounted 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, the left end of the cart 1 is provided with a vertical rod, and the middle part of the push rod 2 is hinged with the upper end of the vertical rod.

In order to better remove dust and broken stones on the brush 5, a vertical baffle plate 11 positioned right above the rotating shaft 4 is arranged inside the shell 3, and the baffle plate 11 is placed in the front-back direction; 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 through bolts.

In order to better collect impurities, a vertical flexible plate 12 is installed on the front side of the shell 3, and the flexible plate 12 is made of leather and plastic.

The utility model discloses during the use, at first start air pump 10, high pressure gas can follow shower nozzle 7 blowout this moment to because shower nozzle 7 is corresponding with impeller 6, consequently the air current can promote pivot 4 and rotate, makes the brush 5 in the pivot 4 then along with rotating together and rotate. When the device is used specifically, the cart 1 is pushed to the crack of the road surface, then the middle part of the whole shell 3, namely the position of the spray head 7 corresponds to the position of the crack, so that the high-pressure air flow blows the rotating shaft 4 to rotate on one side, and the other side can directly blow the crack, so that broken stones, impurities and dust in the crack are blown away.

Meanwhile, when the rotating shaft 4 rotates, the brush 5 on the rotating shaft 4 can clean the pavement, and the rotating shaft 4 has a certain length, so that the brush 5 can clean the pavement on two sides of the crack; is beneficial to the subsequent asphalt construction.

Because the airflow is blown towards the left and the rotating shaft 4 rotates clockwise, the gravel, impurities and dust which are blown by the airflow and brushed by the brush 5 can move leftwards and enter the dust cover 8 along the flexible plate 12 and the shell 3; meanwhile, the filter screen 9 is arranged at the top of the dust cover 8, so under the blocking action of the filter screen 9, sundries can be blocked in the dust cover 8, and meanwhile, gas containing a small amount of dust can diffuse outwards from the filter screen 9.

Through the filtration of filter screen 9, the dust can a large amount of reductions, and the diffusion velocity of dust also can be great by great reduction simultaneously, makes that the dust can be better restrained, is favorable to reducing air pollution.

After the dust cover is used for a period of time, the filter screen 9 can be opened, and the objects such as gravel and the like in the dust cover 8 are cleaned, and meanwhile, the filter screen 9 is cleaned; can be repeatedly used.

Through the right end of the lifting push rod, the friction force between the brush and the ground can be increased, the force of the brush on the ground can be adjusted by the brush, and various sundries can be cleaned.

The device utilizes high-pressure airflow to clean cracks on one hand, and utilizes the high-pressure airflow as the power for rotating the rotating shaft 4 on the other hand, and the brushes 5 are uniformly distributed outside the rotating shaft 4 to form brush rolls, so that the brushes 5 can clean sundries adhered to the inner parts of the cracks and road surfaces on two sides of the cracks; the sundries which are inconvenient to blow can be cleaned more easily; the road surface at two sides of the crack within a certain width range is clean; is beneficial to the subsequent crack pouring operation.

According to the device, the dust cover 8 is arranged at the upper left of the shell 3, and meanwhile, the rotation direction of the rotating shaft 4 and the blowing direction of air flow are utilized, so that sundries can automatically enter the dust cover 8, and a large amount of sundries are prevented from flowing out from a gap between the left side of the shell 3 and the ground through the flexible plate 12; the sundries are collected as much as possible; meanwhile, under the action of the filter screen 9, the dust-proof function can be achieved.

The utility model discloses convenient operation, the structure is ingenious, low cost, and it is convenient to make, and is safe effective, has improved the portability of crack clearance greatly, is favorable to realizing cleaning of full aspect, can realize the collection of debris and the processing of dust.
