Description

Technical Field

[0001] This utility model relates to the technical field of road sweeper vehicle devices, specifically a road sweeper vehicle sweeping width adjustment device. Background Technology

[0002] With social development and progress, the market demand for road sweepers is constantly growing. Future road sweepers will place greater emphasis on multifunctionality, environmental friendliness, and economy to meet cleaning needs in various scenarios. Simultaneously, with technological advancements, the intelligence level of road sweepers will continue to improve to adapt to the challenges of future urban sanitation work.

[0003] For example, CN206752389U discloses an adjustable-width road sweeping device, including a sweeper vehicle. A first support platform is welded to the front of the sweeper vehicle, a solar panel is welded to the top of the first support platform, a transformer is welded to the bottom of the first support platform, a hydraulic pump is welded to the bottom of the transformer, hydraulic rods are welded to both sides of the hydraulic pump, a sweeping device is welded to the side of the support frame away from the hydraulic rods, and the sweeping device includes a second support platform and a small garbage bin.

A nozzle is welded to the output shaft end of the water pump.

[0004] This adjustable-width road sweeping equipment uses hydraulic rods as support frames to increase the adjustability of the sweeping width. It is also equipped with solar panels to provide power to the equipment, making it energy-saving and environmentally friendly. The truck body is welded with a water tank for road sweeping, making the equipment dual-purpose. It can sweep and water the road at the same time, enhancing its functionality and better protecting the road surface.

[0005] As can be seen from the solutions disclosed in the existing patent documents, the dust collection device is located on both sides of the sweeper and above the sweeping device. It can absorb garbage while sweeping. However, this structure lacks a garbage interception and guiding structure, which means that the dust collection device can only absorb the garbage below it. The garbage on both sides of the dust collection device cannot be absorbed, thus limiting the range of garbage absorption. Therefore, the existing technology needs to be improved.

[0020] 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.

[0021] Please see Figure 1-2 The sweeping width adjustment device of the road sweeper shown in the figure includes a sweeper 1, a support plate 11 at the front end of the sweeper 1, and a guide mechanism symmetrically arranged below the support plate 11. The guide mechanism is used to guide the movement of garbage. The guide mechanism includes a guide rod 12 that slides through the inside of the support plate 11. The lower end of the guide rod 12 is connected to a guide plate 13. A spring 14 is slidably sleeved on the outside of the guide rod 12. A screw 15 is connected to the upper end face of the guide plate 13. A nut 16 is threadedly connected to the outside of the screw 15. A sweeping mechanism is symmetrically arranged on one side of the support plate 11. The sweeping mechanism is used to sweep garbage on the ground.

[0022] A drive mechanism is installed at the bottom of the sweeper vehicle 1. The drive mechanism is specifically responsible for providing the power required for sweeping operations. The drive shaft of the drive mechanism is connected to the drive wheel. A flushing mechanism is set at the rear of the sweeper vehicle 1. The flushing mechanism is used to flush the road surface.

[0023] In this setup, the flushing mechanism mainly uses water from the water tank, which is pressurized by a high-pressure water pump and then sprayed out through nozzles to wash the road surface. This can remove stains and garbage from the road, especially during the sweeping process.

[0024] Please see Figure 1-2 The upper end face of the support plate 11 is closely attached to the nut 16. A dust suction mechanism is installed in the lower middle part of the sweeper 1. The dust suction mechanism is used to absorb and store garbage. The screw 15 slides through the inside of the support plate 11.

[0025] With this setup, the dust collection mechanism uses a high-volume dust collection fan and a high-efficiency filtration system to suck garbage and debris into the garbage bin. When the filter is clogged, the internal fully automatic dust-shaking motor will start automatically to clean it, thus ensuring that the sweeper can run continuously for a long time. By rotating the nut 16, the screw 15 can be moved longitudinally, making it easy to adjust the distance between the guide plate 13 and the ground.

[0026] Please see Figure 1-2 The upper end of the spring 14 is connected to the support plate 11, and the lower end of the spring 14 is connected to the guide plate 13.

[0027] With this setup, the guide rod 12 is designed to guide the guide plate 13 to move, preventing the guide plate 13 from rotating automatically around the screw 15. The spring 14 is designed to provide elastic support for the guide plate 13, making the screw 15 and nut 16 more tightly connected. The guide plate 13 is designed to expand the garbage collection range and guide the garbage to move towards the middle of the sweeper 1, so that the dust collection mechanism at the bottom of the sweeper 1 can more easily collect the garbage.

[0028] Please see Figure 1 , Figure 3 and Figure 4 The sweeping mechanism includes a reinforcing seat 2 symmetrically connected to one side of the support plate 11. A drive motor 21 is installed at the end of the reinforcing seat 2. The lower end of the shaft of the drive motor 21 is connected to a rotating disk 22. The lower end face of the rotating disk 22 is connected to a sweeping brush 23. The internal thread of the reinforcing seat 2 is connected to a bolt 24. The lower end of the bolt 24 is connected to a limiting block 25. An adjusting ring 26 is slidably sleeved on the outer side of the limiting block 25. The drive motor 21 is powered by the battery inside the sweeper 1 and converts chemical energy into electrical energy through the battery. Then, it uses this electrical energy to drive the motor.

[0029] In this setup, starting the drive motor 21 drives the rotating disk 22 to rotate, which in turn drives the sweeping brush 23 to sweep the floor.

[0030] Please see Figure 1 , Figure 3 and Figure 4 The lower end of bolt 24 is slidably connected to adjusting ring 26, and cleaning brush 23 is sleeved inside adjusting ring 26;

[0031] In this configuration, rotating the bolt 24 causes the limiting block 25 to rotate, which in turn causes the adjusting ring 26 to move longitudinally. The adjusting ring 26 restrains the sweeping brush 23, thus adjusting the width of the sweeping brush 23's rotation. When the sweeping brush 23 is pulled outward by the driving motor 21, it will spread outward. The longitudinal movement of the adjusting ring 26 can limit the range of the sweeping brush 23's outward spread, thereby adjusting the width of the sweeping brush 23's sweeping of the ground.

[0032] The working principle of this embodiment is as follows: The sweeping width adjustment device of the road sweeper drives the screw 15 to move longitudinally by rotating the nut 16, which facilitates the adjustment of the distance between the guide plate 13 and the ground. The design of the guide rod 12 can guide the guide plate 13 to move and prevent the guide plate 13 from rotating automatically around the screw 15. The design of the spring 14 can provide elastic support for the guide plate 13, so that the screw 15 and the nut 16 are more tightly connected. The design of the guide plate 13 can expand the garbage collection range and guide the garbage to move towards the middle of the sweeper 1, so that the dust suction mechanism at the bottom of the sweeper 1 can more conveniently concentrate and absorb the garbage.

[0033] By starting the drive motor 21, the rotating disk 22 is driven to rotate, which in turn drives the sweeping brush 23 to sweep the ground. By rotating the bolt 24, the limiting block 25 is driven to rotate, which in turn drives the adjusting ring 26 to move longitudinally. The adjusting ring 26 restrains the sweeping brush 23, which can adjust the width of the sweeping brush 23's rotation. When the sweeping brush 23 is pulled outward by the drive motor 21, it will spread outward. The longitudinal movement of the adjusting ring 26 can limit the range of the sweeping brush 23's outward spread, thereby adjusting the width of the sweeping brush 23 sweeping the ground.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
