[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other implementation methods or equivalent replacements obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0029] like Figure 1-7 As shown, a structure with a detachable disc brush and roller brush for a floor scrubber includes a floor scrubber frame 1, a disc brush assembly 2, and a roller brush assembly 3. The floor scrubber frame 1 is mounted with a chain bracket 5 via bolts. The chain bracket 5 is connected to a chain 4 via a bearing 51. A screw 6 is rotatably sleeved on a connecting block at the bottom end of the chain 4.

[0030] The disc brush assembly 2 includes a cleaning bracket 21, which is equipped with two vertical motors 22. The output shaft of the vertical motor 22 is slidably sleeved with a bottom shaft 23, and the bottom shaft 23 is fixedly connected to a disc brush 24. The bottom shaft 23 is rotatably sleeved with a movable plate 25. After the chain 4 passes through the cleaning bracket 21, the screw 6 is threadedly connected to the movable plate 25. The cleaning bracket 21 is connected to a side support rod 26 through a support, and the side support rod 26 is detachably connected to the No. 1 connection hole 11 of the floor scrubber frame 1;

[0031] Twist the screw 6 to connect it to the movable plate 25, and fix the side support rod 26 to the No. 1 connecting hole 11 through bolts and nuts, so that the disc brush assembly 2 is installed on the floor washing vehicle frame 1; separate the screw 6 from the movable plate 25, and separate the side support rod 26 from the No. 1 connecting hole 11, so as to remove the disc brush assembly 2 from the floor washing vehicle frame 1; the side support rods 26 at both ends of the disc brush assembly 2 have upper connecting rods and lower connecting rods, and the lower connecting rods at both ends are connected by a cross bar to ensure that the cleaning bracket 21 and the disc brush 24 are parallel to the ground during normal operation, thereby ensuring the rigidity of the disc brush during operation and ensuring that the cleaning ability of the floor washing vehicle meets the standard;

[0032] The roller brush assembly 3 includes a support bracket 31 and two horizontal motors 32. The support bracket 31 is connected to a roller brush cover 34 via a rotating shaft 33. The output shaft of the horizontal motor 32 is rotatably sleeved with the support bracket 31. The output shaft of the horizontal motor 32 is connected to a roller brush shaft 36 via a transmission belt 35. The roller brush shaft 36 is installed with a roller brush. The roller brush shaft 36 is rotatably sleeved with the roller brush cover 34. The screw 6 is threadedly connected to the roller brush cover 34. The support bracket 31 is connected to a roller brush connecting rod 37 via a support. The roller brush connecting rod 37 is detachably connected to the No. 2 connecting hole 12 of the floor scrubber frame 1.

[0033] Connect the screw rod 6 to the roller brush cover 34, and fix the roller brush connecting rod 37 to the second connecting hole 12 with bolts and nuts, thereby installing the roller brush assembly 3 on the floor scrubber frame 1; separate the screw rod 6 from the roller brush cover 34, and separate the roller brush connecting rod 37 from the second connecting hole 12, thereby removing the roller brush assembly 3 from the floor scrubber frame 1;

[0034] The top end of the chain extends and is installed to the handle of the floor scrubber frame 1, so that the cleaning worker can pull the chain at any time and temporarily raise the disc brush 24 or the roller brush to avoid ground obstacles and prevent hard collisions: the bottom end of the chain 4 moves upward, the movable plate 25 moves vertically upward, the disc brush 24 is separated from the ground, and the roller brush cover 34 rotates upward and the roller brush is separated from the ground; if the disc brush 24 or the roller brush needs to be raised for a long time, the chain 4 can be wrapped around the handle of the floor scrubber frame 1; the vertical motor 22 and the horizontal motor 32 are powered by batteries.

[0035] In some embodiments of the present invention, preferably, the center line of the rotating shaft 33 coincides with the center line of the output shaft of the horizontal motor 32, and the tension state of the transmission belt 35 remains stable during the process of the chain 4 pulling the roller brush cover 34 to rotate.

[0036] In some embodiments of the present invention, preferably, the top of the movable plate 25 is fixedly connected to a return spring 27, and the top of the return spring 27 is fixedly connected to the cleaning bracket 21; after the force on the chain is released, under the combined action of the gravity of the disc brush 24 and the return spring 27, the disc brush 24 moves down and rotates into contact with the ground again for cleaning work.

[0037] In some embodiments of the present invention, preferably, the rotating shaft 33 is installed with a torsion spring 38, and the two ends of the torsion spring 38 are respectively in contact with the protrusions of the rotating shaft 33 and the protrusions of the roller brush cover 34. When the roller brush cover 34 rotates upward, the protrusions of the rotating shaft 33 and the protrusions of the roller brush cover 34 squeeze the torsion spring 38; after the force on the chain 4 is released, under the combined action of the roller brush cover 34, the gravity of the roller brush shaft 36 and the torsion spring 38, the roller brush shaft 36 rotates in the opposite direction and re-rotates and contacts with the ground for cleaning work.

[0038] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
