Abstract
Description
Technical Field
[0001] This utility model relates to a sweeper, and more specifically, to a leaf sweeper. Background Technology
[0002] Spring and autumn are peak seasons for sanitation workers, as they are also the seasons when leaves fall. The continuous falling of leaves, the difficulty in concentrating them for sweeping, and the numerous corners and edges of roads pose significant challenges to leaf cleanup. Existing street sweepers collect litter and fallen leaves using negative pressure suction. However, the suction cups of these sweepers are fixed in position, limiting their effective cleaning range to the flat surface directly beneath the vehicle's path. They are often ineffective in hard-to-reach areas such as roadside edges, sidewalks, green belt edges, or under guardrails. Leaf removal in these areas still requires secondary manual cleaning by sanitation workers, which is not only labor-intensive and inefficient but also poses safety hazards.
[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0017] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0018] A type of leaf sweeper, such as Figures 1-4 As shown, the system includes a vehicle body 1 and a cleaning assembly located at the bottom of the vehicle body 1. An extension tube assembly is connected to the cleaning assembly, and a suction nozzle 15 is provided at the end of the extension tube assembly away from the cleaning assembly. A fixing mechanism for fixing the extension tube assembly is provided on one side of the vehicle body 1. The cleaning assembly includes an air duct 3 located at the bottom of the vehicle body 1 and connected to a centrifugal fan, and several suction cups 2 located at the bottom end of the air duct 3.
[0019] The extension tube assembly includes a connecting tube 4 and a free tube 5. The connecting tube 4 connects to one side of the vehicle body 1 from the cleaning component air duct 3. The free tube 5 is a PVC steel wire hose and is connected to the end of the connecting tube 4 away from the cleaning component. A pipe joint connects the connecting tube 4 and the free tube 5. The pipe joint can be a universal joint, which can rotate at multiple angles, allowing the free tube 5 to move more freely. The free tube 5 is a flexible hose, which is more convenient to use. The pipe joint can also be a straight pipe or a straight pipe with a valve. Straight pipes have higher strength and ensure the service life of the overall structure. The suction nozzle 15 is located at the free end away from the universal joint. A handheld bracket can be provided at the end of the free tube 5, allowing the operator to operate it by holding the handheld bracket on the free tube 5, making it more convenient to use. The connecting tube 4 is connected to the air duct 3 through a solenoid valve. Through a series of measures such as electronic control, such as the driver's seat or remote control, the connecting tube 4 can be disconnected from the air duct 3, so that the suction cup 2 can be used normally.
[0020] The fixing mechanism includes a storage box 6 located on one side of the vehicle body 1 and a limiting component located inside the storage box 6 to prevent the free tube 5 from detaching from the storage box 6. The limiting component includes elastic claws 8 arrayed on the bottom wall of the storage box 6. The cross-section of the elastic claws 8 is arc-shaped, and both ends of the elastic claws 8 are chamfered, which has a good guiding effect. The elasticity of the elastic claws 8 combined with the chamfers allows the free tube 5 to be better inserted into the elastic claws 8. Since the free tube 5 is a flexible tube, it can be inserted into the storage box 6 in a wavy direction. One side of the storage box 6 is open, and an opening 9 is provided on the outer wall of the storage box 6 for the free tube 5 to extend into. The opening 9 extends towards the opening and is open, making it easier to insert the free tube 5. A cover 7 can be provided on one side of the storage box 6. The cover 7 and the storage box 6 can be rotatably connected by a hinge and fixed relative to each other by a latch, which can completely store the free tube 5 of the extension tube assembly into the storage box 6. The limiting assembly also includes a mounting plate 10 fixedly connected to the storage box 6 by bolts. A telescopic rod 11 is rotatably connected to the mounting plate 10. The end of the telescopic rod 11 facing away from the mounting plate 10 is fixedly connected to the outer peripheral wall of the elastic claw 8. The telescopic rod 11 is rotatably connected to the inner bottom wall of the storage box 6, so that the elastic claw 8 is relatively rotatably connected to the inner bottom wall of the storage box 6, which allows the elastic claw 8 to rotate to different angles, making it more convenient to fix the free tube 5.
[0021] A support plate 12 is fixedly connected to one side of the machine body by bolts. A support rod 13 is provided on the support plate 12. A clamp 14 is provided at one end of the support rod 13. The end of the connecting pipe 4 away from the cleaning component is placed in the clamp 14. The connecting pipe 4 is clamped by bolts and clamp 14, which provides a good support effect and makes the connecting pipe 4 more stable on one side of the machine body, thus ensuring the quality of the overall structure.
[0022] Working principle: When the entire cleaning vehicle is moved to a specific location, and fallen leaves on both sides of the road, especially on pedestrian crossings, cannot be swept away, simply open the cover 7, take out the free tube 5 from the storage box 6, and open the solenoid valve at the connecting pipe 4. The free tube 5 is a flexible hose, making it more convenient for workers to handle. Workers only need to aim the suction nozzle 15 at the end of the hose at the top of the pedestrian crossing and use the fan to suction, which can also clean up the fallen leaves on the pedestrian crossing. This reduces the workload of sanitation workers and makes road cleaning more complete, ensuring work efficiency.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
