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.

[0020] like Figure 1 and Figure 2 As shown in the figure, a front-end cleaning device for a road sweeper includes a fixed base 1, a connecting arm 2, and a disc brush 3 connected in sequence, wherein the fixed base 1 is fixedly installed on the body of the road sweeper.

[0021] In this embodiment, the fixing base 1 is fixedly installed on the front end of the sweeper body by welding or other fixing methods.

[0022] like Figure 1As shown, the fixed base 1 includes a fixed vertical plate 203 fixedly installed on the body of the sweeper. A pair of connecting side plates 204 are fixed on the side wall of the fixed vertical plate 203 away from the body of the sweeper. The connecting side plates 204 and the fixed vertical plate 203 are arranged perpendicularly.

[0023] Preferably, the first end of the connecting arm 2 is hinged to the fixed base 1.

[0024] In this embodiment, the first end of the connecting arm 2 is inserted between the two connecting side plates 204 of the fixed base 1, and is hinged together with the two connecting side plates 204 via the hinge shaft 202.

[0025] Preferably, a flexible adjustment component 4 is provided between the second end of the connecting arm 2 and the fixed base 1. The flexible adjustment component 4 is used to adjust the height position of the disc brush 3. The disc brush 3 is rotatably mounted on the bottom of the second end of the connecting arm 2 and is driven to rotate by the driving component 5.

[0026] Preferably, the lower end of the fixed base 1 is provided with multiple pairs of first locking holes 101, and the first end of the connecting arm 2 and one of the pairs of first locking holes 101 are inserted with a locking pin 6 to lock the position of the connecting arm 2.

[0027] In this embodiment, the first locking hole 101 is located at the lower end of the connecting side plate 204 on the side away from the fixed vertical plate 203.

[0028] Preferably, the upper end of the fixed base 1 is provided with a pair of second locking holes 102, and the first end of the connecting arm 2 and one of the pair of first locking holes 101 are inserted with a locking pin 6 to realize the storage of the disc brush 3.

[0029] In this embodiment, the second locking hole 102 is located at the upper end of the connecting side plate 204 near the fixed vertical plate 203.

[0030] In this embodiment, at least one through hole (not shown in the figure) is provided at the position where the connecting arm 2 is inserted into the connecting side plate 204. The size and position of the through hole are adapted to the size and position of the first locking hole 101.

[0031] When the sweeper is not in operation, the position of the disc brush 3 needs to be locked. The locking operation procedure is as follows: First, the operator raises the disc brush 3 and aligns the through hole with one of the first locking holes 101 or the second locking hole 102. Then, the locking pin 6 is inserted into the through hole and the first locking hole 101 or the second locking hole 102 to lock the connecting arm 2 so that it cannot rotate, thereby ensuring the relative fixation between the sweeping device and the sweeper body.

[0032] In this embodiment, the raised and locked sweeping device can separate the disc brush 3 from the road surface, avoiding continuous contact between the disc brush 3 and the road surface, thereby reducing the wear of the bristles on the disc brush 3 and extending the service life of the sweeping device.

[0037] In this embodiment, the connector 406 can be a ring or a ring hook.

[0038] The procedure for adjusting the lowest position of the disc brush 3 using the flexible adjustment component 4 is as follows: First, the operator removes the connecting hook 405 from the fastening chain 407, thereby unlocking the fastening adjuster from the first fixing frame 401 or the second fixing frame 402; then, the adjusting screw 403 is turned to adjust the length of the adjusting screw 403 extending out of the annular frame 404, thereby adjusting the length of the entire flexible adjustment component 4 accordingly; finally, the connecting hook 405 is re-fixed to the fastening chain 407, and the flexible adjustment component 4 can then pull the connecting arm 2 to a suitable angle, thereby enabling free adjustment of the height position of the disc brush 3.

[0039] Preferably, the disc brush 3 is rotatably mounted on the mounting frame 201, the mounting frame 201 is fixedly mounted on the connecting arm 2, and the driving component 5 is mounted on the mounting frame 201.
