[0062] 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.

[0063] Example 1:

[0064] like Figures 1 to 6 As shown, this utility model provides a suction nozzle for a sweeper. The suction mechanism includes a negative pressure pipe 2 for connecting the pump on the sweeper, arranged on the top side of the nozzle housing 1, a connection hole 201 opened on the nozzle housing 1, and a negative pressure chamber 202 connected to the connection hole 201, which is used to collect and transport garbage by utilizing negative pressure.

[0065] The nozzle housing 1 also includes a mounting bracket 102 arranged on the side of the nozzle housing 1, and casters 103 arranged on the mounting bracket 102 for supporting the nozzle housing 1. The casters 103 mounted on the nozzle housing 1 via the mounting bracket 102 can provide support when the nozzle housing 1 is close to the ground, and also ensure that the nozzle housing 1 does not directly contact the ground.

[0066] The separation mechanism includes an air blowing pipe 4 arranged on the top side of the suction nozzle housing 1 and an inclined nozzle 401 arranged on the inner side wall of the negative pressure chamber 202 for blowing up garbage stuck to the ground. The airflow generated when the garbage truck creates negative pressure is injected into the air blowing pipe 4 and the inclined nozzle 401. The inclined nozzle 401 blows air towards the ground in an angle range of 30 to 40 degrees, which can interfere with the leaves sticking to the ground and achieve the purpose of enhancing the cleaning effect of the equipment.

[0067] Example 2:

[0068] Based on Example 1, in order to reduce the arrangement range of the negative pressure chamber 202 and avoid excessively large areas reducing the negative pressure inside the negative pressure chamber 202, thus affecting the suction power for garbage, the protective wheels 307 on the gathering plate 301 are designed to prevent the gathering plate 301 from contacting and impacting the curb, thereby damaging the equipment.

[0069] The gathering mechanism includes a rotating mounting frame 3 arranged on the inner wall of the negative pressure chamber 202; a gathering plate 301 arranged on the rotating mounting frame 3 for collecting waste from the side of the suction nozzle housing 1, which can gather waste from a larger area toward the negative pressure chamber 202; a triangular gathering plate 302 arranged on the suction nozzle housing 1 for waste with a middle section, which gathers the middle section of waste between two suction nozzle housings 1 toward the negative pressure chamber 202; an adjustment drive assembly arranged on the suction nozzle housing 1 for adjusting the angle of the rotating mounting frame 3 and the gathering plate 301; and a safety component arranged on the gathering plate 301 for buffering contact between the gathering plate 301 and other objects.

[0070] The adjustment drive assembly includes an adjustment motor 303 disposed on the top of the nozzle housing 1 for providing driving force, a drive rod 304 disposed inside the nozzle housing 1 for connecting the adjustment motor 303 and the rotating mounting bracket 3, the output end of the adjustment motor 303 driving the rotating mounting bracket 3 to rotate, thereby changing the angle of the gathering plate 301, and a limiting sleeve 305 disposed on the drive rod 304 to restrict the drive rod 304 to rotate in a fixed position.

[0071] The safety component includes a mounting block 306 disposed at the outermost end of the gathering plate 301, and a protective wheel 307 disposed on the mounting block 306 for contacting objects. The protective wheel 307 prevents the gathering plate 301 from contacting and impacting the curb, thereby preventing damage to the equipment.

[0072] Example 3:

[0073] Based on Example 1, in order to ensure that the nozzle housing 1 can be close to the ground when cleaning is needed and away from the ground when cleaning is not needed, the device can be protected from damage due to prolonged proximity to the ground.

[0074] The mounting mechanism includes a top mounting bracket 5 disposed on the top side of the nozzle housing 1, a bottom mounting bracket 501 disposed on the top of the nozzle housing 1, a synchronizing rod 502 disposed between the top mounting bracket 5 and the bottom mounting bracket 501 for controlling the distance between the top mounting bracket 5 and the bottom mounting bracket 501, a rotating shaft 503 disposed at both ends of the synchronizing rod 502 for connecting the top mounting bracket 5 and the bottom mounting bracket 501, and a rotating shaft 503 disposed between the top mounting bracket 5 and the bottom mounting bracket 501 for controlling the distance between the top mounting bracket 5 and the bottom mounting bracket 501. Synchronous rod 2 504 is arranged at both ends of synchronous rod 2 504 and is used to connect the rotating shaft 2 505 of the top mounting frame 5 and the bottom mounting frame 501. When the suction nozzle housing 1 moves, the distance between the top mounting frame 5 and the bottom mounting frame 501 will increase synchronously. Synchronous rod 1 502 and synchronous rod 2 504 connecting the top mounting frame 5 and the bottom mounting frame 501 will be flipped through the corresponding rotating shaft 1 503 and rotating shaft 2 505. Synchronous rod 1 502 and synchronous rod 2 504 can move synchronously with the hydraulic telescopic rod 506 to ensure the stability of the suction nozzle housing 1 when it is raised and lowered.

[0075] The lifting drive assembly includes a hydraulic telescopic rod 506 arranged on the top side of the suction nozzle housing 1 for driving the relative movement of the top mounting bracket 5 and the bottom mounting bracket 501, and rotating connecting blocks 507 arranged at both ends of the hydraulic telescopic rod 506. The rotating connecting blocks 507 cooperate with the lifting mounting block 508 to transmit the driving force of the hydraulic telescopic rod 506. When the hydraulic telescopic rod 506 is extended, its two ends connected to the rotating connecting blocks 507 will rotate on the lifting mounting block 508, thereby pushing the suction nozzle housing 1 away from the sweeper.

[0076] Working principle:

[0077] To use this device, the hydraulic telescopic rod 506 must first be activated. When the hydraulic telescopic rod 506 extends, its two ends, connected to the rotating connecting block 507, will rotate on the lifting mounting block 508, thereby pushing the suction nozzle housing 1 away from the sweeper. When the suction nozzle housing 1 moves, the distance between the top mounting bracket 5 and the bottom mounting bracket 501 will increase synchronously. The synchronizing rods 502 and 504 connecting the top mounting bracket 5 and the bottom mounting bracket 501 will rotate through the corresponding rotating shafts 503 and 505. The synchronizing rods 502 and 504 can synchronize the movement of the hydraulic telescopic rod 506, ensuring the stability of the suction nozzle housing 1 when it is raised and lowered. The casters 103 mounted on the suction nozzle housing 1 via the mounting bracket 102 can provide support when the suction nozzle housing 1 is close to the ground, and also ensure the stability of the suction nozzle housing. Body 1 does not directly contact the ground. The adjustment motor 303 is started, and the output end of the adjustment motor 303 drives the rotating mounting bracket 3 to rotate, thereby changing the angle of the gathering plate 301. This allows the gathering plate 301 to gather garbage from a larger area toward the negative pressure chamber 202. At the same time, the triangular gathering plate 302 between the two suction nozzle housings 1 also gathers the garbage in the middle part toward the negative pressure chamber 202. The gathered garbage is transported to the inside of the sweeper under the action of negative pressure through the negative pressure pipe 2 and the connecting hole 201. At the same time, the airflow generated when the garbage truck creates negative pressure is injected into the air blowing pipe 4 and the tilting nozzle 401. The tilting nozzle 401 blows air toward the ground at an angle of 30 to 40 degrees, which can interfere with the leaves sticking to the ground and achieve the purpose of enhancing the cleaning effect of the equipment.

[0078] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
