Description

Technical Field

[0001] This utility model relates to the field of highway maintenance equipment technology, specifically to a sweeper brush. Background Technology

[0002] With increasing automation, sweepers have become an indispensable cleaning tool in road maintenance. During the sweeping process, hair, thin threads, and other long, thin objects on the road surface easily become entangled in the brushes. Over time, the accumulated dirt and grime cause the brushes to bend and clump together, affecting their cleaning effectiveness. This often requires manual cleaning or even replacement of the brushes. In addition, the wear and tear on the brush bristles varies at different points during use. If a part of the brush is damaged, the entire brush needs to be replaced, resulting in wasted costs. Utility Model Content

[0003] The purpose of this utility model is to provide a sweeper brush with a cleaning tooth assembly on the side of the brush, which can clean the hair and other dirt wrapped around the brush, improve the cleanliness of the bristles, and enhance the cleaning performance of the brush.

[0004] This utility model includes a brush roller, on which several brush modules are installed, and each brush module is equipped with several bristles; a protective cover is installed on the upper part of the brush roller, and a cleaning tooth assembly is installed on the inner side of the protective cover, with several cleaning teeth installed at intervals on the cleaning tooth assembly, and the cleaning teeth are interspersed between the bristles.

[0005] With the above structure, when the bristles rotate with the roller, the cleaning teeth scrape off the hair and other dirt stuck to and tangled on the bristles to ensure that the bristles are clean and to ensure their performance; it also avoids the bristles from becoming brittle and reducing their cleaning ability due to too much hair or other dirt stuck to or tangled on them.

[0006] Preferably, the cleaning tooth comprises an upper section, a middle section, and a lower section from top to bottom, with the external dimensions of the upper, middle, and lower sections decreasing sequentially to form an inverted cone-shaped structure.

[0007] Preferably, the upper section has an internal cavity, the outer contour of the middle section matches the shape of the cavity, and the middle section is telescopically installed inside the cavity of the upper section.

[0008] Preferably, the lower section is a curved arc structure, and the bending direction of the lower section is the same as the rotation direction of the roller.

[0009] Preferably, the brush module and the brush roller are detachably connected.

[0010] Preferably, a dust suction chamber is connected to the side of the protective cover, and the dust suction chamber is connected to a dust suction device.

[0011] In summary, this utility model has the following beneficial effects: 1. A cleaning tooth assembly is provided on the side of the brush. When the brush bristles rotate with the roller, the cleaning teeth on the cleaning tooth assembly scrape off the hair and other dirt stuck to and wrapped around the brush bristles to ensure that the brush bristles are in a clean state and to ensure their performance. This prevents the brush bristles from becoming clumped together due to too much hair or other dirt stuck to or wrapped around them, which would reduce the cleaning ability. 2. The dimensions of the upper, middle and lower sections of the cleaning teeth decrease sequentially, thus forming an inverted cone structure. At the same time, the cleaning teeth are arranged with appropriate spacing. The surface of the cleaning teeth is smooth and has an inverted cone structure. Under the action of gravity, combined with the suction of the dust collection chamber located on the side of the cover, the dirt cleaned from the bristles can be quickly removed from the cleaning teeth and transported away by the dust collection chamber. 3. The middle section of the cleaning tooth is retractably installed in the cavity of the upper section; with the help of an external power mechanism, the middle section of the cleaning tooth can be extended or retracted when needed to adapt to bristles of different structures, making it more versatile. 4. The brush module and brush roller are detachably connected. The brush bristles are installed on the brush module. The integrated design allows the brush module to be replaced when the bristles in a certain area are damaged, saving costs and improving efficiency. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] The orientations mentioned in this specification are based on the orientation of the sweeper brush of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0016] like Figures 1 to 2 As shown, a sweeper brush includes a brush roller 1 with several brush modules 2 mounted on it, and several brush bristles 3 mounted on each brush module 2. The central shaft of the brush roller 1 is connected to a sprocket, which is connected to a drive mechanism via a chain. Driven by the drive mechanism and the chain, the brush roller 1 rotates, thereby cleaning the road. A dust collection chamber 7 is connected to the side of the protective cover 4, and the dust collection chamber 7 is connected to a dust collection device. While the brush bristles 3 clean the road surface garbage, the dust collection device adsorbs and collects the garbage swept up, improving cleaning efficiency.

[0017] Furthermore, a protective cover 4 is installed on the upper part of the brush roller 1, and a cleaning tooth assembly 5 is installed on the inner side of the protective cover 4. Several cleaning teeth 6 are installed at intervals on the cleaning tooth assembly 5. The cleaning teeth 6 are interspersed between the bristles 3. When the bristles 3 rotate with the roller, the cleaning teeth 6 scrape off the hair and other dirt stuck to and wrapped on the bristles 3 to ensure that the bristles 3 are in a clean state and to ensure their performance. This avoids the bristles 3 from becoming brittle due to too much hair or other dirt stuck to or wrapped on them, which would reduce their cleaning ability.

[0018] Furthermore, such as Figure 3 and Figure 4 As shown, the cleaning teeth 6, from top to bottom, include an upper section 601, a middle section 602, and a lower section 603. The outer dimensions of the upper section 601, the middle section 602, and the lower section 603 decrease sequentially, thus forming an inverted cone structure. Preferably, in this embodiment, the cleaning tooth assembly 5 is disposed above the protective cover 4, and the cleaning teeth 6 are disposed in a vertical position. At the same time, the cleaning teeth 6 are arranged with appropriate spacing. The surface of the cleaning teeth 6 is smooth and has an inverted cone structure. Under the action of gravity, in conjunction with the suction of the dust collection chamber 7 disposed on the side of the protective cover 4, the dirt cleaned from the brush bristles 3 can be quickly removed from the cleaning teeth 6 and carried away by the dust collection chamber 7.

[0019] Furthermore, the upper section 601 has an internal cavity, and the outer contour of the middle section 602 matches the shape of the cavity. The middle section 602 is telescopically installed in the cavity of the upper section 601. With the help of an external power mechanism, the middle section 602 of the cleaning tooth 6 can be extended or retracted when needed to adapt to different bristle structures 3, making it more versatile. At the same time, it can better allow the cleaning tooth 6 to penetrate into the root of the bristle 3 to clean the entangled material at the root of the bristle 3, making the cleaning more thorough. It should be noted that the external power mechanism used in this device can be a hydraulic mechanism or a pneumatic mechanism, etc., which are conventional technical means and will not be described in detail here.

[0020] Furthermore, the lower section 603 is a curved arc structure, and the bending direction of the lower section 603 is the same as the rotation direction of the roller. The arc structure of the lower section 603 makes the cleaning teeth 6 more powerful in removing stubborn tangled objects, and the cleaning effect is better, especially for tangled objects that are difficult to remove from the bristles 3. At the same time, the bending angle of this arc structure needs to be reasonably set according to the cleaning needs, and the ease with which the tangled objects can be removed from the cleaning teeth 6 also needs to be considered.

[0021] Furthermore, such as Figure 5 and Figure 6 As shown, the brush module 2 is detachably connected to the brush roller 1. The mounting plate of the brush module 2 has threaded holes, and the brush module 2 is installed on the roller by bolts. Several independent brush modules 2 are installed on the roller at intervals. The bristles 3 are installed on the brush module 2. The integrated design allows the brush module 2 to be replaced when a local bristle 3 is damaged, saving costs and improving efficiency. At the same time, the brush modules 2 can be arranged in rows along the axial direction of the roller as shown in the figure, or they can be staggered in the axial direction to meet different cleaning needs.

[0022] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
