the clutch handle 1 is hinged to a mower frame through a clutch handle rotating fulcrum 2, the clutch flexible shaft 3 is mounted on the mower frame through two clutch flexible shaft supports 4, the upper end of the clutch flexible shaft 3 is connected with the clutch handle 1, the lower end of the clutch flexible shaft 3 is connected with a clutch tension spring 6, a clutch tension support 7 is hinged to the mower frame through a clutch tension support rotating fulcrum 8, a tension wheel 5 is mounted at the upper end of the clutch tension support 7, and the other end of the clutch tension spring 6 is connected to the clutch tension support 7 between the tension wheel 5 and the clutch tension support rotating fulcrum 8; a driving belt pulley 9 and a driven belt pulley 10 are rotatably mounted on the mower frame, a belt 11 is arranged on the driving belt pulley 9 and the driven belt pulley 10, and the tensioning wheel 5 is matched with the belt 11; the belt brake frame 12 is hinged on the mower frame through a belt brake frame rotating fulcrum 13, a brake block 15 is fixed on the belt brake frame 12 on the right side of the belt brake frame rotating fulcrum 13, and the brake block 15 compresses the driven belt pulley 10; the clutch tension spring fixing seat 16 is fixed on the mower frame, a belt brake frame tension spring 14 is installed on the clutch tension spring fixing seat 16, and the lower end part of the belt brake frame tension spring 14 is connected to a belt brake frame 12 on the left side of a belt brake frame rotation pivot 13.
The clutch handle 1 is arranged on the mower frame above the belt 11.
The clutch tensioning support 7 is hinged to the mower frame below the belt 11, and the belt brake frame 12 is hinged to the mower frame on the right side of the clutch tensioning support 7.
The clutch handle 1 rotates around the clutch handle rotating fulcrum 2; two ends of the clutch flexible shaft 3 are respectively connected with the clutch handle 1 and the clutch tension spring 6, and the other end of the clutch tension spring 6 is connected to the clutch tensioning bracket 7; the clutch flexible shaft 3 is arranged on the two clutch flexible shaft supports 4; the clutch tensioning bracket 7 rotates around a clutch tensioning bracket rotating fulcrum 8; the brake block 15 is fixed on the belt brake frame 12; the belt brake frame 12 rotates around a belt brake frame rotation fulcrum 13; the belt brake frame tension spring 14 is connected on the belt brake frame 12, and the brake block 15 is always pressed on the driven belt pulley 10 in a belt separation state.
The working principle of the utility model is as follows:
When the clutch handle 1 is in the disengaged position, the driven pulley 10 is not in the working state, and the belt 11 is in the disengaged state, and large torque cannot be transmitted. At this time, the brake block 15 is always pressed against the driven pulley 10, thereby avoiding the follow-up phenomenon of the driven pulley 10 under various conditions.
When the driven belt pulley 10 is required to work, the clutch handle 1 is pulled up clockwise to a working position, the clutch tensioning support 7 is driven to rotate around the rotary fulcrum 8 of the clutch tensioning support through the clutch flexible shaft 3 and the clutch tension spring 6, the tension belt 11 achieves torque force transmission, the belt brake frame 12 is driven to rotate around the rotary fulcrum 13 of the belt brake frame at the moment, the brake block 15 is separated from the driven belt pulley 10, and therefore the driven belt pulley 10 can work.
