Description

Technical Field

[0001] The utility model relates to the field of sanitation vehicles, in particular to a novel cleaning brush for sanitation vehicles. Background Art

[0002] Sanitation vehicles play an important role in urban maintenance. They are special vehicles used for urban appearance tidying and cleaning, and perform road sweeping and road maintenance work.

[0003] The floor brush is an important part of the sanitation vehicle for cleaning the road surface. The floor brush is driven by the rotating mechanism to clean the road surface, and the dust generated in the process is sucked away by the dust collection device. Airflow is generated during the rotation of the floor brush, so the floating dust will escape outward to form dust. These scattered dusts are not easily sucked away by the dust collection device and will pollute the air. After settling, they will adhere to the road surface again and affect the cleaning effect of the sanitation vehicle. The purpose of this utility model is to propose a floor brush structure that can solve the above problems to improve the cleaning effect of the sanitation vehicle. Utility Model Content

[0004] The utility model aims to provide a novel floor cleaning brush for sanitation vehicles to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: it includes a cover shell, a rotating shaft, spokes and brush strips, the top of the cover shell is provided with a connecting pipe connected to the cover shell, the side of the connecting pipe is provided with a connecting pipe connected to the connecting pipe, the rotating shaft is installed on the connecting pipe and forms a rotating pair with the connecting pipe, the spokes are located on the inner side of the cover shell, the ends of the brush strips are connected and radially distributed, the bottom surface of the brush strip is provided with bristles and the end of the brush strip is connected to the rotating shaft through the spokes.

[0006] In order to optimize the above technical solution, further measures are taken as follows: the rotating shaft is installed on the connecting pipe through the bearing ring, the bearing ring blocks the top of the connecting pipe, the bearing ring improves the rotation stability of the rotating shaft on the connecting pipe, and at the same time the bearing ring blocks the top of the connecting pipe to prevent dust from leaving from the top of the connecting pipe.

[0007] As a further improvement of the above technical solution: it also includes a scraper, which is located on the side adjacent to the inner surface of the cover. When the dust and foreign matter adhering to the cover reaches a certain thickness, it will be scraped off by the scraper. At the same time, the scraper can form an airflow during rotation to help inhale air.

[0008] As a further improvement to the technical solution: the projection of the spokes in the vertical direction on the horizontal plane coincides with the projection of the brush bar on the horizontal plane, and the setting position of the spokes corresponds to the setting position of the brush bar, ensuring the rotational stability of the brush bar during rotation.

[0009] As an improvement to the above technical solution: the number of spokes corresponds to the number of brush bars, thereby ensuring the connection strength between the spokes and the brush bars.

[0010] Furthermore: there is a gap between the bottom of the cover and the road surface and the side of the brush bar cannot be completely surrounded. Setting the gap helps external air to be sucked into the cover through the gap, thereby improving the dust collection effect. At the same time, the cover can collect the swept dust and reduce dust.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides a novel floor sweeping brush for sanitation vehicles. A cover is provided to concentrate dust formed when the brush bristles sweep the road surface inside the cover, which helps to improve the dust absorption effect of the dust suction device and avoid the formation of dust. During the process, the air sucked into the cover cooperates with the scraper to drive the airflow, causing the dust to form a suspended state, thereby improving the dust suction efficiency of the dust suction device and improving the cleaning effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-2The utility model provides a new type of sanitation vehicle cleaning brush, including a cover shell 1, a rotating shaft 2, spokes 3, brush strips 4 and a scraper 5. The top of the cover shell 1 is provided with a connecting pipe 101 connected to the cover shell 1, and the side of the connecting pipe 101 is provided with a connecting pipe 102 connected to the connecting pipe 101. The rotating shaft 2 is installed on the connecting pipe 101 to form a rotating pair with the connecting pipe 101. The rotating shaft 2 is installed on the connecting pipe 101 through a bearing ring 201 to realize that the rotating shaft 2 and the connecting pipe 101 form a rotating pair. The bearing ring 201 seals The top of the connecting pipe 101 is blocked, and the spokes 3 are located on the inner side of the cover shell 1. The ends of the brush strips 4 are connected and radially distributed, and the ends of the brush strips 4 are extended and connected in a ring shape. The bottom surface of the brush strip 4 is provided with bristles 401, and the ends of the brush strips 4 are connected to the rotating shaft 2 through the spokes 3. The projection of the spokes 3 on the horizontal plane in the vertical direction coincides with the projection of the brush strips 4 on the horizontal plane. The number of spokes 3 corresponds to the number of brush strips 4. There is a gap between the bottom end of the cover shell 1 and the road surface and the side of the brush strip 4 cannot be completely surrounded. The scraper 5 is located on the side and adjacent to the inner surface of the cover shell 1.

[0020] Working principle: The top of the rotating shaft 2 is fixedly connected to the rotating mechanism on the sanitation vehicle and the connecting pipe 101 is connected to the air inlet of the dust collecting device on the sanitation vehicle. During the process, the rotating mechanism drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the bristles 401 on the brush strip 4 through the spokes 3 to clean the road surface. The dust swept up during the process is confined in the cover 1. The dust generated during the cleaning process is small, and because the dust is confined by the cover 1, the dust collecting device can suck away the dust through the air inlet, and the cleaning effect on the road surface is good.

[0021] There is a gap between the bottom end of the cover shell 1 and the road surface, which cannot completely surround the side of the brush strip 4. Such a mechanism design allows the external air to enter the cover shell 1 through the gap due to the negative pressure when the vacuum cleaner sucks away the dust in the cover shell 1, which helps to reduce the dust formed when the bristles 401 clean the road surface. At the same time, the airflow entering the cover shell 1 helps to keep the dust suspended in the cover shell 1, avoiding dust sedimentation and helping the swept dust to be sucked away by the vacuum cleaner.

[0022] During the rotation of the rotating shaft 2, the scraper 5 is connected to the spoke 3 and will produce synchronous movement. When the dust thickness on the inner surface of the cover shell 1 reaches a certain thickness, the dust is scraped off by the scraper 5 to prevent the dust from adhering too thickly and affecting the rotation of the spoke 3. The scraper 5 can drive the air flow in the cover shell 1 when rotating, which helps the dust to remain suspended and be sucked away by the dust collection equipment.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
