[0001] The utility model belongs to the field of road cleaning equipment, and specifically relates to a novel road cleaning machine and a road cleaning vehicle. Background Art

[0002] At present, urban roads are generally cleaned by a sweeper installed under a sweeper. Existing road sweepers generally use a single sweeping roller or a negative pressure vacuum cleaner for cleaning operations, which has low cleaning efficiency and unsatisfactory cleaning effect. Utility Model Content

[0003] In order to address the deficiencies in the prior art, the utility model aims to provide a new type of road sweeper. The device can efficiently clean roads by sweeping with a roller brush assembly in combination with negative pressure suction, which can significantly improve the cleaning quality. The height of the sweeping roller can be easily adjusted to adapt to different road conditions.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A novel road sweeper comprises a hood and a roller brush assembly, wherein the roller brush assembly comprises two power-driven cleaning rollers, which rotate in opposite directions and are arranged horizontally side by side perpendicular to the cleaning direction; the cleaning rollers are adjustable up and down and installed in a hood with a downward opening, and support wheels are arranged on the outside of the hood; the exhaust port above the hood is connected to a crushing and collecting mechanism through a negative pressure fan.

[0006] Preferably, the cleaning roller at the front side in the cleaning direction is higher than the cleaning roller at the rear side.

[0007] Preferably, the rotation speed of the front cleaning roller in the cleaning direction is higher than that of the rear cleaning roller.

[0008] Preferably, a collecting hopper is provided above the machine cover, and the exhaust port is provided in the middle of the top of the collecting hopper.

[0009] Preferably, the cleaning rollers are connected to corresponding driving motors, and the driving motors of the two cleaning rollers are respectively arranged on both sides of the hood.

[0010] Preferably, a motor shield is fixedly provided on the side of the hood, and the drive motor is arranged in the motor shield.

[0011] Preferably, heat dissipation holes are provided on the motor shield.

[0012] Preferably, an adjustment hole and a mounting hole are vertically opened on the side wall of the hood, and a mounting seat is movably provided outside the hood. The end of the cleaning roller movably passes through the adjustment hole and is rotatably mounted on the mounting seat through a bearing structure. The mounting seat can be adjusted up and down and fixed in the mounting hole.

[0013] Preferably, the brushes on the cleaning roller are designed in a zigzag shape, and the brushes on the two cleaning rollers are symmetrically arranged.

[0014] Furthermore, the present application also proposes a road sweeper using the above-mentioned new road sweeper, wherein the new road sweeper is installed at the bottom of the road sweeper through a lifting mechanism.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model is more conducive to the collection and guidance of the collecting hopper on the top of the machine cover, so that the garbage materials are gathered to the exhaust port, and then the garbage swept into the machine cover can be effectively sucked and collected through the suction effect of the negative pressure fan.

[0017] 2. The two cleaning rollers of the present application are independently controlled in speed by corresponding connected motors. The front cleaning roller is slightly higher than the rear cleaning roller. Its high-speed rotation is more conducive to directly throwing up the light and heavy material garbage that needs to be collected and sending them to the low-speed rotating cleaning roller at the rear. The low-speed rotating cleaning roller at the rear then sends the thrown garbage into the crushing and collection mechanism through the suction of the negative pressure fan to complete the collection process.

[0018] 3. The motor shield is fixed on the side of the hood, and the drive motor is set inside the motor shield, which can effectively protect the drive motor and avoid damage during cleaning operations. In addition, there are heat dissipation holes on the motor shield, which is more conducive to the heat dissipation of the motor and prolongs the service life of the motor.

[0019] 4. The mounting seat is fixed in the mounting hole by a bolt structure. By changing the fixing position of the bolt structure in the strip hole, the vertical height of the mounting seat is adjusted to achieve the height adjustment of the cleaning roller in the vertical direction. This enables the device to adjust the installation height of the roller brush assembly according to the actual road conditions, making the installation and commissioning of the cleaning roller more convenient.

[0020] 5. The brushes on the cleaning rollers are designed in a zigzag pattern, and the brushes on the two cleaning rollers are symmetrically arranged. The brush structure with a zigzag design on the cleaning rollers is more conducive to sweeping the garbage on the ground to the middle of the two cleaning rollers, thereby significantly improving the road cleaning efficiency.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0026] Embodiment 1:

[0027] like Figure 1-3 As shown, the utility model proposes a new type of road sweeper, including a hood 1 and a roller brush assembly. A support wheel 4 is provided on the outside of the hood 1. The support wheel 4 can be a universal wheel for effectively supporting the sweeper. A collecting hopper 2 is provided above the hood 1, and an exhaust port 20 is provided in the middle of the top of the collecting hopper 2. The exhaust port 20 is connected to the crushing and collecting mechanism through a negative pressure fan. The collection and guidance of the collecting hopper 2 on the top of the hood 1 is more conducive to the gathering of garbage materials to the exhaust port 20, and then the garbage swept into the hood 1 can be effectively sucked and collected through the suction effect of the negative pressure fan.

[0028] The roller brush assembly includes two cleaning rollers 5 with independent power drives, which rotate in opposite directions and are arranged horizontally side by side perpendicular to the cleaning direction. The two cleaning rollers 5 are respectively connected to the corresponding driving motors 51. In the cleaning direction, the front cleaning roller 5 is higher than the rear cleaning roller 5, and the rotation speed of the front cleaning roller 5 is higher than that of the rear cleaning roller 5.

[0029] Specifically, the speeds of the two cleaning rollers 5 are independently controlled by corresponding connected motors. The front cleaning roller 5 is slightly higher than the rear cleaning roller 5, so that the high-speed rotation of the front cleaning roller 5 is more conducive to directly throwing up the light and heavy material garbage that needs to be collected and sending them to the rear low-speed rotating cleaning roller 5. The rear low-speed rotating cleaning roller 5 then sends the thrown garbage into the crushing and collection mechanism through the suction of the negative pressure fan to complete the collection process.

[0030] In the present application, the motors connected to the two cleaning brushes are independently controlled and can adjust the rotation speed according to the speed of the sweeper, the size of the objects to be cleaned, etc., which is more energy-saving and environmentally friendly and increases the service life and endurance of the equipment.

[0031] In addition, the driving motors 51 of the two cleaning rollers 5 are respectively arranged on both sides of the hood 1, and the two driving motors 51 are arranged separately, which is conducive to the heat dissipation of the motor. A motor shield 3 is fixed on the side of the hood 1, and the driving motor 51 is arranged in the motor shield 3, which can effectively protect the driving motor 51 and avoid bumps and damages during the cleaning operation. In addition, the motor shield 3 is provided with heat dissipation holes 30, which is more conducive to the heat dissipation of the motor and improves the service life of the motor.

[0032] Embodiment 2:

[0033] The difference from Example 1 is that in this embodiment, the cleaning roller 5 is adjustable up and down and installed in the hood 1 with the opening downward. Specifically, the two side walls of the hood 1 are vertically symmetrically provided with adjustment holes 11 and mounting holes 12, and a mounting seat 6 is movably provided on the outside of the hood 1. The end of the cleaning roller 5 movably passes through the adjustment hole 11 and is rotatably installed on the mounting seat 6 through a bearing structure. The driving motor 51 connected to the cleaning roller 5 is also installed on the corresponding mounting seat 6. The mounting seat 6 is fixed in the mounting hole 12 by a bolt structure, and the mounting hole 12 is a strip hole. By changing the fixed position of the bolt structure in the strip hole, the vertical height of the mounting seat 6 is adjusted, and the height adjustment of the cleaning roller 5 in the vertical direction is achieved, so that the device can adjust the installation height of the roller brush assembly according to the actual road conditions, and the installation and debugging of the cleaning roller 5 is more convenient.

[0034] Embodiment 3:

[0035] like Figure 4 As shown, the difference from the above embodiment is that the brush 50 on the cleaning roller 5 in this embodiment is designed in a zigzag shape, and the brushes 50 on the two cleaning rollers 5 are symmetrically arranged. The zigzag structure is a zigzag line arranged on the circumferential surface of the cleaning roller 5 at a certain angle from the middle of the cleaning roller 5 to both sides. The zigzag brush structure on the cleaning roller 5 is more conducive to moving the garbage on the ground to the middle of the two cleaning rollers 5 for sweeping, thereby significantly improving the road cleaning efficiency.

[0036] Embodiment 4:

[0037] Correspondingly, the present application also proposes a road sweeper, which uses the new type of road sweeper in the above embodiment, and the new type of road sweeper in the above embodiment is installed at the bottom of the road sweeper through a lifting mechanism, and the lifting mechanism can adopt a structure such as a hydraulic cylinder. When the road sweeper is cleaning, the lifting mechanism is used to drive the new type of road sweeper of the present application to move downward and contact the road surface, and the road sweeper can move in coordination with the movement to complete efficient cleaning operations.
