Title: DRIVE CONNECTION FRAME FOR USE IN DEVICE FOR SWEEPING GROUND UNDER ROAD FENCE
Abstract:
A drive connection frame for use in a device for sweeping the ground under a road fence consists of a curved connection plate (7), a connection bar assembly (3) and a gear drive mechanism. The gear drive mechanism consists of a driving spur gear (5), a connection bar central large spur gear (6), a connection bar central large bevel gear (8), horizontal drive bevel gears (9), a disc brush-driving bevel gear (11), a horizontal shaft (12), a disc brush connection shaft (13), and a connection bar main shaft (14). The connection bar central large spur gear (6) is coaxial with the connection bar central large bevel gear (8) and coaxially connected to a top end of the connection bar main shaft (14). Moreover, the connection bar central large spur gear (6) meshes with the driving spur gear (5). The horizontal shaft (12) is installed at a horizontal bar of the connection bar assembly (3). The horizontal drive bevel gear (9) at one end of the horizontal shaft (12) meshes with the connection bar central large bevel gear (8). The horizontal drive bevel gear (9) at the other end of the horizontal shaft (12) meshes with the disc brush-driving bevel gear (11). The drive connection frame drives a disc brush to operate, such that the disc brush can effectively cross upright poles of a fence, thereby ensuring a smooth sweeping operation.
