Sweeping machine, sweeping brush assembly, sweeping brush floating hydraulic system and control method of sweeping brush floating hydraulic system
The invention discloses a sweeping vehicle, a sweeping brush assembly, a sweeping brush floating hydraulic system and a control method of the sweeping brush floating hydraulic system, the sweeping brush floating hydraulic system comprises a sweeping brush supporting oil cylinder, a pressure reducing valve, a first electromagnetic on-off valve, a second electromagnetic on-off valve, an oil pump and an oil tank, and one of a rod cavity and a rodless cavity of the sweeping brush supporting oil cylinder is connected with the oil tank; the other one of the rod cavity and the rodless cavity of the sweeping brush supporting oil cylinder is connected with the oil pump through a first oil way branch and a second oil way branch which are connected in parallel, the first oil way branch is provided with a first electromagnetic on-off valve, and the second oil way branch is connected with a pressure reducing valve and a second electromagnetic on-off valve in series; according to the hydraulic system, the sweeper can automatically adjust the operation height along with the concave-convex change of the road surface and the abrasion of the sweeper, manual adjustment is not needed, the workload of a user is reduced, the abrasion of the sweeper cannot be aggravated due to the concave-convex change of the road surface, the sweeping effect on the uneven road surface is improved, and the service life of the sweeper is prolonged; and the interaction force between the ground and the sweeping brush can be adjusted, and the sweeping effect is adjusted.
本发明公开了扫路车、扫刷总成、扫刷浮动液压系统及其控制方法，该扫刷浮动液压系统包括扫刷支撑油缸、减压阀、第一电磁通断阀、第二电磁通断阀、油泵及油箱，扫刷支撑油缸有杆腔及无杆腔中的一个与油箱连接，扫刷支撑油缸有杆腔及无杆腔中的另一个通过并联的第一油路支路及第二油路支路与油泵连接，第一油路支路设置有第一电磁通断阀，第二油路支路串联有减压阀及第二电磁通断阀；上述液压系统使扫刷可随路面的凹凸变化及扫刷的磨损自行调节作业高度，无需手动调节，减少了用户工作量，不会由于路面凹凸变化加剧扫刷磨损，提高对不平整路面的清扫效果，延长扫刷使用寿命，能够对地面与扫刷之间的相互作用力进行调节，实现对清扫效果的调节。
