Description

Technical Field

[0001] The utility model relates to the technical field of environmental sanitation equipment, in particular to a device for adjusting the angle of a sweeping brush of a road sweeper. Background Art

[0002] At present, in the operation of road sweepers on the market, the sweeping brush groove is welded on the upper and lower flat plates of the sweeping disk to realize the fixing function of the sweeping brush. However, after the road sweeper operates for a period of time, local wear of the sweeping brush occurs. Or after changing the supplier of the sweeping brush, due to the change in the size of the sweeping brush, the cleaning rate of the cleaning operation will change accordingly. And the existing structure cannot allow environmental sanitation operators to adjust the angle of the sweeping brush, resulting in the scrapping of the sweeping brush before it is fully worn out and cannot be used, frequent replacement of the sweeping brush, and relatively high use costs. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for adjusting the angle of a sweeping brush of a road sweeper.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for adjusting the angle of a sweeping brush of a road sweeper, including a sweeping disk motor, a motor fixing seat, an upper flat plate of the sweeping disk and a lower flat plate of the sweeping disk. The sweeping disk motor is fixed on the motor fixing seat, and the output shaft of the sweeping disk motor is fixedly connected with the upper flat plate of the sweeping disk. A plurality of sweeping brush clips are connected at intervals along the circumferential direction between the outer sides of the upper flat plate of the sweeping disk and the lower flat plate of the sweeping disk. Long slot holes are respectively arranged along the transverse direction on the outer side of the lower surface of the upper flat plate of the sweeping disk corresponding to each sweeping brush clip, and round holes are respectively arranged on the outer side of the upper surface of the lower flat plate of the sweeping disk corresponding to each sweeping brush clip. The upper end of the sweeping brush clip is slidably connected to the corresponding long slot hole through a pin shaft, and the lower end of the sweeping brush clip is rotatably connected to the corresponding round hole through a pin shaft. An adjusting rod is connected between the upper flat plate of the sweeping disk and the lower flat plate of the sweeping disk along the vertical direction. The adjusting rod is used to adjust the distance between the upper flat plate of the sweeping disk and the lower flat plate of the sweeping disk, so as to adjust the angle of the sweeping brush clip.

[0006] Further, the upper end of the adjusting rod is welded and fixed on the upper flat plate of the sweeping disk, and the lower end of the adjusting rod is locked and connected to the lower flat plate of the sweeping disk through a nut.

[0007] Further, a compression spring is sleeved on the adjusting rod and is connected between the upper flat plate of the sweeping disk and the lower flat plate of the sweeping disk.

[0008] Further, the output shaft of the sweeping disc motor is fixedly connected to the upper flat plate of the sweeping disc through the upper clamping plate and the lower clamping plate of the motor in a locking manner. The upper clamping plate of the motor is located on the upper end face of the upper flat plate of the sweeping disc, and the lower clamping plate of the motor is located on the lower end face of the upper flat plate of the sweeping disc. The upper clamping plate and the lower clamping plate of the motor are connected to the upper flat plate of the sweeping disc through a bolt and nut assembly. The beneficial effects of the present utility model adopting the above technical solutions are as follows: when the sweeping brush is worn to a certain extent, the angle of the sweeping brush clip is changed by adjusting the nut on the adjusting rod, so as to make full use of the sweeping brush. At the same time, it can ensure that the cleaning rate of the cleaning operation is significantly improved, the service life of the sweeping brush of the cleaning vehicle is prolonged, and the use cost of the sweeping brush is reduced.

[0013] As Figures 1 - 3 shown, the device for adjusting the sweeping brush angle of the cleaning vehicle of the present utility model includes a sweeping disc motor 1, a motor fixing seat 2, an upper flat plate 3 of the sweeping disc and a lower flat plate 6 of the sweeping disc. The sweeping disc motor 1 is fixed on the motor fixing seat 2, and the output shaft of the sweeping disc motor 1 is fixedly connected to the upper flat plate 3 of the sweeping disc. Among them, the output shaft of the sweeping disc motor 1 is fixedly connected to the upper flat plate 3 of the sweeping disc through the upper clamping plate 8 and the lower clamping plate 9 of the motor in a locking manner. The upper clamping plate 8 of the motor is located on the upper end face of the upper flat plate 3 of the sweeping disc, and the lower clamping plate 9 of the motor is located on the lower end face of the upper flat plate 3 of the sweeping disc. The upper clamping plate 8 and the lower clamping plate 9 of the motor are connected to the upper flat plate 3 of the sweeping disc through a bolt and nut assembly.

[0014] A plurality of sweeping brush clips 5 (for fixing the sweeping brush) are connected at intervals along the circumferential direction between the outer sides of the upper flat plate 3 of the sweeping disc and the lower flat plate 6 of the sweeping disc. Specifically, long slot holes are respectively arranged horizontally on the lower surface outside of the upper flat plate 3 of the sweeping disc corresponding to each sweeping brush clip 5, and round holes are respectively arranged on the upper surface outside of the lower flat plate 6 of the sweeping disc corresponding to each sweeping brush clip 5. The upper end of the sweeping brush clip 5 is slidably connected to the corresponding long slot hole through a pin shaft 4, and the lower end of the sweeping brush clip 5 is rotatably connected to the corresponding round hole through a pin shaft 4.
