The adjusting seat 8 is hinged to the U-shaped connecting bent plate 603 of the support 6 through a pin shaft, and is hinged to one end of the adjusting rod 7 through a pin shaft, the other end of the adjusting rod 7 is connected to the lug plate 605 of the support 6 through a pin shaft, and the adjusting seat 8 can rotate up and down around the U-shaped connecting bent plate 603 by adjusting the length of the adjusting rod 7, so that the front and back grounding inclination angles of the disc brush 12 can be adjusted.
As shown in fig. 8, the motor mounting seat 9 includes a connecting plate 901 and a mounting seat plate 902, the connecting plate 901 of the motor mounting seat 9 is mounted on the adjusting seat 8 through three sets of bolts and nuts, the mounting holes on the connecting plate 901 are three semicircular and evenly distributed oblong holes, and the left and right inclination angles of the disc brush 12 can be adjusted by adjusting the mounting positions of the oblong holes of the connecting plate 901 on the adjusting seat 8.
The motor 10 is installed on the installation seat plate 902 of the motor installation seat 9 through four groups of bolt nuts, the disc brush installation seat 11 is fixedly installed on the output shaft of the motor 10 through the bolt nuts and the shaft end check ring, and the disc brush 12 is installed on the disc brush installation seat 11 through the bolt nuts.
The nozzle frame 13 is installed on the motor installation seat 9 through bolts and nuts, and the nozzle frame 13 is used for installing a low-pressure nozzle and plays a role in real-time dust fall.
The specific working principle of the cleaning device is as follows: when the road sweeper enters a sweeping operation state, firstly, the sweeping device descends under the action of self gravity until bristles of the disc brush 12 are in contact with the ground, at the moment, the floating function of the floating oil cylinder 4 is opened, the sweeping device is in a floating operation state, and the grounding pressure of the disc brush 12 is realized by adjusting the pressure of an oil inlet of a small cavity of the floating oil cylinder 4.
When the road sweeper encounters uneven road surfaces in a cleaning operation state, the cleaning device can be adjusted timely along with the uneven road surfaces to be cleaned, and the grounding pressure of the disc brush 12 can be kept unchanged in the fluctuation of the road surfaces, so that the cleaning operation effect of the road sweeper is ensured, the disc brush 12 is prevented from being damaged due to hard impact between the disc brush 12 and the ground, and the service life of the disc brush 12 is prolonged.
The chain 3 is used for providing an upward pulling force for the cleaning device after the cleaning device descends to the position where the bristles of the disc brush 12 contact the ground under the action of self gravity, and the chain 3 and the floating oil cylinder 4 are matched to jointly realize the floating function of the cleaning device.
In addition, when the road sweeper is used for sweeping, the grounding pressure of the disc brush can be continuously adjusted in time, so that firstly, when the working condition of sweeping the road surface is severe, the grounding pressure of the disc brush can be increased in time, and the sweeping operation effect is improved; and secondly, when the working condition of cleaning the road surface does not need larger grounding pressure of the disc brush, the grounding pressure of the disc brush can be properly reduced, the condition that the abrasion of the brush hair is quicker can be avoided, the service cycle of the disc brush is prolonged, and meanwhile, the waste of the energy of the road sweeper can also be avoided.
When the road sweeper enters a walking state, the sweeping device is lifted to a state that the height of the disc brush 12 from the ground is the highest under the action of the floating oil cylinder 4, as shown in fig. 4.
The front and back grounding inclination angles of the disc brush 12 are realized by adjusting the adjusting rod 7, the left and right inclination angles of the disc brush 12 can be realized by adjusting the mounting position of the long round hole on the adjusting seat 8 on the motor mounting seat 9, the two modes not only meet the adjusting requirements of the left and right front and back inclination angles of the disc brush 12, and ensure that the disc brush 12 only contacts the ground in an effective cleaning area, thereby greatly reducing the abrasion of brush hair, prolonging the service cycle of the disc brush 12, and having simple structure, convenient adjustment and low cost.
Through the description of the embodiments of the sweeping device and the sweeping machine of the road sweeper, the embodiments of the sweeping device and the sweeping machine of the road sweeper can be seen to have at least one or more of the following advantages:
1. the floating function of the cleaning device is realized through the matching of the floating oil cylinder and the chain, the cleaning device can be self-adapted to the height fluctuation change of the cleaned road surface, and meanwhile, the grounding pressure of the disc brush can be kept unchanged in the height fluctuation change of the road surface, the disc brush is prevented from being damaged due to hard impact on the road surface, the service life of the disc brush is prolonged, and the cleaning efficiency is improved;
