WIPO Patent Application WO/2020/034644
Kind Code:
A1
Abstract:
A cleaning apparatus for the ground under a road guardrail. A fixing frame (1) is fixed in front of a vehicle. One end of a swing frame (2) is hingedly connected to the fixing frame (1). A swing frame swing mechanism is mounted between the fixing frame (1) and the swing frame (2) to drive the swing frame (2) to swing horizontally. An operating mechanism support lifting mechanism is mounted between the swing frame (2) and an operating mechanism frame (21) to drive the operating mechanism frame (21) to parallelly move up and down. The middle portion of a swing rod (22) is hingedly connected to the operating mechanism support (21). The tail portion of the swing rod (22) is connected to the operating mechanism support (21) by means of a swing rod swing mechanism. The swing rod swing mechanism drives the swing rod (22) to swing horizontally. A disc-like brush assembly is mounted on the head end of the swing rod (22). An obstacle sensing assembly is mounted on the swing rod (22). A sensing element in the obstacle sensing assembly is in signal connection with a power element of the swing rod swing mechanism. A positioning wheel mechanism is mounted on the operating mechanism support (21). The cleaning apparatus effectively saves a lot of labor and material resource, features high working efficiency and good working performance, and completely resolves the problem of the cleaning of blind angles on the ground under fences.
