摘要：【中文】本发明涉及一种扫路机的吸口升降装置。该装置包括有机体框架，位于机体框架下端设置有吸尘部件，吸尘部件包括有底板，底板下侧边檐围合有环形橡胶裙边，底板经连杆机构与机体框架铰接，位于底板后端设置有吸尘管件，底板上表面设置有铰接座，吸尘管件外围设置U型支架，U型支架与铰接座铰接，U型支架经伸缩油缸与机体框架铰接，底板上设置有喷淋软管，底板下连接有喷淋头，喷淋软管出水口与喷淋头接通，由于U型支架以及底板上表面铰接座的存在，使得该装置中吸尘部件在升降时，U型支架会随着吸尘部件的升降对喷淋软管进行对应抵触状态的改变，从而改变喷水软管是否处于接通的状态，该装置适用于工业生产中，具有很强的实用性。 【EN】The invention relates to a suction port lifting device of a road sweeper. The device comprises a machine body frame, a dust absorption part is arranged at the lower end of the machine body frame and comprises a bottom plate, an annular rubber skirt is enclosed and combined at the lower side edge of the bottom plate, the bottom plate is hinged with the machine body frame through a connecting rod mechanism, a dust absorption pipe fitting is arranged at the rear end of the bottom plate, a hinged seat is arranged on the upper surface of the bottom plate, a U-shaped support is arranged at the periphery of the dust absorption pipe fitting and hinged with the hinged seat, the U-shaped support is hinged with the machine body frame through a telescopic oil cylinder, a spray hose is arranged on the bottom plate, a spray head is connected below the bottom plate, a water outlet of the spray hose is communicated with the spray head, due to the existence of the U-shaped support and the hinged seat on the upper surface of the bottom plate, when the dust absorption part in the device is lifted, the U-shaped support can change the corresponding collision, has strong practicability.
