Description

Technical Field

[0001] This utility model relates to the field of sweeping and brushing technology, and in particular to a sweeping and brushing cleaning mechanism. Background Technology

[0002] The sweeper brush is an important component of a sweeper truck, mainly used for sweeping and cleaning roads. The sweeper brush is usually composed of components such as sweeping discs and drive motors. Through rotation and brushing actions, it effectively removes garbage and dirt from the road surface. Sweepers and their brushes are suitable for mechanized cleaning and sweeping operations in various places such as urban roads, highways, and squares.

[0003] However, due to issues such as road planning or tree branches extending beyond the roadbed, regular-length sweepers cannot clean up trash at the corners of the road. Furthermore, the bristles of the sweeper are generally fixed on the outside of the sweeping disc, with a fixed outward length and angle. When facing narrow gaps, the bristles cannot reach into them for cleaning, resulting in cleaning dead spots and affecting the cleaning effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sweeping brush cleaning mechanism that solves the technical problems that the conventional length of the existing sweeping brush is insufficient to cope with complex road cleaning situations, and that the fixed outward length and angle of the brush bristles make it impossible to clean stains in narrow gaps. This invention achieves the purpose of extending the length of the sweeping brush and expanding the cleaning area.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sweeping brush cleaning mechanism, including a mounting base and a sweeping brush disc, wherein the bottom of the mounting base is provided with a cleaning mechanism for adjusting the extension length, height and sweeping angle of the sweeping brush disc, and the cleaning mechanism is provided with a sweeping brush converging mechanism for converging and adjusting the sweeping range of the sweeping brush disc.

[0006] The cleaning mechanism includes an electric telescopic rod installed at the bottom of the mounting base. A telescopic component for extending the cleaning length of the brush disc is installed at the free end of the bottom of the electric telescopic rod. A swivel component for adjusting the cleaning angle of the brush disc is provided on one side of the telescopic component. A connecting arm is installed on the swivel component, and a mounting plate is installed at the other end of the connecting arm. A rotating shaft is rotatably connected in a rotating hole on the mounting plate, and the bottom of the rotating shaft is connected to the top of the brush disc. Brush bristles are installed in a circular array at the bottom outer edge of the brush disc. A drive motor for driving the rotating shaft to rotate is installed on the mounting plate.

[0007] A further improvement is that the telescopic assembly includes an adjusting crossbeam installed at the free end of the electric telescopic rod. A lead screw is rotatably connected to a rotating hole on the adjusting crossbeam, and a threaded slide is threadedly connected to the lead screw and slidably connected to a guide groove at the bottom of the adjusting crossbeam. An extension rod is installed at the bottom of the threaded slide, and a drive motor for driving the lead screw to rotate is installed on the adjusting crossbeam.

[0008] A further improvement is that the guide groove at the bottom of the adjusting beam is a U-shaped structure, the lead screw is rotatably connected inside the guide groove, and the threaded slide is a U-shaped block that is perfectly matched with the guide groove.

[0009] A further improvement is that the sweeping assembly includes a U-shaped seat installed at the right end of the extension rod, a rotating shaft is rotatably connected in a rotating hole on the U-shaped seat, the left end of the connecting arm is connected to the rotating shaft, a driven gear is installed at the bottom of the rotating shaft, a sweeping motor is installed in a mounting groove on the right side of the bottom of the extension rod, and a driving gear that meshes with the driven gear is connected to the output end of the sweeping motor.

[0010] A further improvement is that the left end of the connecting arm has a U-shaped structure that matches the U-shaped seat.

[0011] A further improvement is that the brush retraction mechanism includes an electric lifting rod installed on the side of the connecting arm, and a retraction disk is installed at the bottom free end of the electric lifting rod. The retraction disk has a frustum structure, and a conical hole with the same diameter as the brush disk is opened through the retraction disk.

[0012] By employing the above technical solution, this utility model provides a sweeping brush cleaning mechanism, which has at least the following beneficial effects:

[0013] 1. This utility model uses an electric telescopic rod, telescopic components, and sweeping components to adjust the height of the sweeping brush disc from the ground, its extension length, and its sweeping angle, so as to adapt to cleaning tasks at different heights and street corners, thereby increasing the cleaning range of the device.

[0014] 2. This utility model uses an electric lifting rod to move the retracting disc downwards, thereby adjusting the bristles at the bottom of the sweeping disc to be retracted from the outside. This allows the sweeping disc to reach into narrower gaps for cleaning, thus improving the adaptability of the device. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Addressing the shortcomings of existing technologies where the conventional length of the sweeping brush is insufficient to handle complex road cleaning situations, and where the fixed bristle extension length and angle prevent cleaning stains in narrow gaps, this embodiment provides a sweeping brush cleaning mechanism. Please refer to... Figures 1-5This embodiment provides a sweeping mechanism that can extend the sweeping brush length and expand the cleaning area. The sweeping mechanism includes a mounting base 1 and a sweeping brush disc 2. The bottom of the mounting base 1 is equipped with a cleaning mechanism 3 that adjusts the extension length, height, and sweeping angle of the sweeping brush disc 2. The cleaning mechanism 3 is equipped with a sweeping brush retraction mechanism 4 that adjusts the sweeping range of the sweeping brush disc 2. The cleaning mechanism 3 allows for targeted adjustments to the sweeping length, height, and angle of the sweeping brush disc 2 to adapt to different cleaning environments. When cleaning stains in narrow crevices, the sweeping brush retraction mechanism 4 retracts the bristles of the sweeping brush disc 2, allowing it to reach into the crevices for cleaning and avoiding cleaning dead zones.

[0031] Since the extension length of conventional sweeping brushes in existing technology is insufficient to handle complex road cleaning situations, this device is equipped with a cleaning mechanism 3. The cleaning mechanism 3 includes an electric telescopic rod 301 installed at the bottom of the mounting base 1. A telescopic component 302 for extending the cleaning length of the sweeping brush disc 2 is installed at the free end of the bottom of the electric telescopic rod 301. A sweeping swing component 303 for adjusting the cleaning angle of the sweeping brush disc 2 is provided on one side of the telescopic component 302. A connecting arm 304 is installed on the sweeping swing component 303, and a mounting plate 305 is installed at the other end of the connecting arm 304. A rotating shaft 306 is rotatably connected to the rotating hole on the 05, and the bottom of the rotating shaft 306 is connected to the top of the sweeping brush disk 2. The brush bristles are arranged in a circular array at the bottom outer edge of the sweeping brush disk 2. A drive motor 307 is installed on the mounting plate 305 to drive the rotating shaft 306 to rotate. When the drive motor 307 on the mounting plate 305 is started, the rotating shaft 306 is rotated, which in turn drives the sweeping brush disk 2 to rotate. Then, according to the height of the ground to be cleaned, the electric telescopic rod 301 is started to push the telescopic component 302 and the sweeping brush disk 2 on it to move down to contact the ground to carry out the cleaning work.

[0032] When cleaning streets, if a vehicle cannot enter a street corner with a certain depth, the standard length of the sweeping brush 2 cannot clean it. Therefore, the device is equipped with a telescopic component 302. The telescopic component 302 includes an adjusting beam 3021 installed at the free end of the electric telescopic rod 301. A lead screw 3022 is rotatably connected in a rotating hole on the adjusting beam 3021. A threaded slide 3023 is threadedly connected to the lead screw 3022 and is slidably connected to the guide groove at the bottom of the adjusting beam 3021. An extension rod 3024 is installed at the bottom of the threaded slide 3023. A drive motor 3025 is installed on the adjusting beam 3021 to drive the lead screw 3022 to rotate.

[0033] The guide groove at the bottom of the adjusting beam 3021 has a U-shaped structure. The lead screw 3022 is rotatably connected to the inside of the guide groove, and the threaded slide 3023 is a U-shaped block that is perfectly matched with the guide groove. When the drive motor 3025 is started, the lead screw 3022 is rotated, which causes the threaded slide 3023 on the lead screw 3022 to slide to the right along the inner wall of the guide groove. This causes the extension rod 3024 at the bottom of the threaded slide 3023 to extend to the right, thereby extending the cleaning length of the brush disk 2 to adapt to different cleaning scenarios.

[0034] Since the cleaning angle of the brush disc 2 needs to be adjusted frequently during the cleaning process to achieve a fan-shaped cleaning area and thoroughly clean the road, the device is also equipped with a sweeping assembly 303. The sweeping assembly 303 includes a U-shaped seat 3031 installed at the right end of the extension rod 3024. A rotating shaft 3032 is rotatably connected in a rotating hole on the U-shaped seat 3031, and the left end of the connecting arm 304 is connected to the rotating shaft 3032. A driven gear 3033 is installed at the bottom of the rotating shaft 3032. A sweeping motor 3034 is installed in a mounting slot on the right side of the bottom of the extension rod 3024, and the output end of the sweeping motor 3034 is connected to a driving gear 3035 that meshes with the driven gear 3033.

[0035] The left end of the connecting arm 304 is a U-shaped structure that matches the U-shaped seat 3031. When the sweeping motor 3034 is started, it drives the drive gear 3035 to rotate, which in turn drives the driven gear 3033 that meshes with it to rotate. This causes the rotating shaft 3032 on the driven gear 3033 to rotate within the U-shaped seat 3031, and drives the connecting arm 304 and the sweeping brush 2 on it to rotate and swing, forming a fan-shaped cleaning area to thoroughly clean the road in front of the sweeper and increase the cleaning area.

[0036] Example 2

[0037] Based on Example 1, such as Figures 1-5 As shown, during the cleaning process, narrow gaps are inevitably encountered. Due to the outward extension of the bristles at the bottom of the brush disc 2, it is impossible for it to reach into the gap for cleaning. Therefore, the device is also equipped with a brush retraction mechanism 4. The brush retraction mechanism 4 includes an electric lifting rod 401 installed on the side of the connecting arm 304, and a retraction disc 402 is installed at the bottom free end of the electric lifting rod 401. The retraction disc 402 has a frustum structure, and a conical hole with the same diameter as the brush disc 2 is opened through the retraction disc 402. When encountering a narrow gap, the electric lifting rod 401 is activated to drive the retraction disc 402 to move down, thereby retracting the bristles at the bottom of the brush disc 2 until the brush disc 2 can enter the gap, thereby cleaning the gap and improving the adaptability of the device.
