Detailed Description

The invention is further described with reference to the accompanying drawings in which:

as shown in fig. 1-4, the soil rotating machine for highway engineering comprises a suspension bracket 1, an input shaft 2, a reduction gearbox 3, a frame 4, a press roller 5, a soil rotating cutter shaft 6, a soil rotating cutter holder 7 and a soil rotating cutter 8, wherein the reduction gearbox 3 is arranged at the central position of the frame 4, the output shaft of the reduction gearbox 3 is ensured to be coaxial with cutter shaft mounting holes on two side plates of the frame 4 through the frame 4, the suspension bracket 1 is arranged above the frame 4 and at the rear part of the reduction gearbox 3, the input shaft 2 is arranged at the rear part of the reduction gearbox 3, the soil rotating cutter 8 is arranged on the cutter holder 7, the soil rotating cutter holder 7 is welded on the soil rotating cutter shaft 6, one end of the soil rotating cutter shaft 6 is arranged on the side plate of the frame 4 through a bearing, the other end of.

The soil-rotating cutter shaft comprises a bearing 9, a side plate bearing chamber 10, a soil-retaining ring 11, a shaft head 12, a soil-rotating cutter shaft tube 13, a soil-rotating cutter holder 7, a connecting flange 14, a connecting sleeve 15 and a box body bearing chamber 16, the soil-rotating cutter holder 7 is welded on the circumference of the soil-rotating cutter shaft tube 13, the bearing 9 is installed on the upper portion of the side plate bearing chamber 16, the shaft head 12 and the connecting flange 14 are respectively welded at two ends of the soil-rotating cutter shaft tube 13, the connecting sleeve 15 is installed on the connecting flange 14, the soil-retaining ring 11 is respectively welded on the shaft head 12 and the connecting sleeve 15, the soil-retaining ring 11 on the shaft head 12 is matched with a clamping groove of the side plate bearing chamber 16, and the soil.
