[0002] After the completion of highway engineering construction, due to the influence of various factors such as geological conditions, construction technology, and material quality, the subgrade may appear rough and uneven or locally protruding.

8. The integrated roadbed crushing and leveling machine according to claim 7, characterized in that, The mounting frame (2) is fixedly connected to the road roller (1) through the fixing frame (32) and the equipment frame (34), and the fixing frames (32) are reinforced by fixing plates (33).

9. The method of using the integrated roadbed crushing and leveling machine based on an energy-saving motor according to claim 8, characterized in that, Includes the following steps: S1. First, install this device on the road roller (1) so that the device can move with the road roller (1) in order to crush the protruding parts of the roadbed that need to be crushed. S2. By activating the two first electric push rods (7), the moving frame can be moved longitudinally along the mounting frame (2), thereby adjusting the height of the ring cutter (15) according to the standard height of the roadbed measured by the total station. S3. By activating the second electric push rod (31), the height of the adjustment frame can be adjusted through the U-shaped frame (30), thereby adjusting the height of multiple crushing discs (28). This allows the height of multiple crushing discs (28) to be adjusted according to the required roadbed height, so that the roadbed can be impact-crushed after cutting. S4. By starting the energy-saving drive motor (12), the transmission shaft (13) is driven to rotate. With the support of the tool holder (14), the ring cutter (15) can be driven to rotate. The rotating ring cutter (15) can cut the roadbed when it moves with the road roller (1). S5. When the gear column (16) rotates with the transmission shaft (13), it can drive the reciprocating screw (21) to rotate under the meshing transmission action with the driven gear (29). When the reciprocating screw (21) rotates, it can make the slip ring (22) move longitudinally along the reciprocating screw (21) under the transmission cooperation with the slip ring (22). In this way, multiple crushing discs (28) can be driven to move longitudinally through the connecting plate (23), the mounting rod (25) and the support plate (26). Therefore, when the crushing disc (28) moves downward, it can squeeze the roadbed sand and gravel after cutting. S6. By starting the energy-saving variable frequency motor (35), the crushing disc (28) is driven to rotate. At this time, the multiple crushing teeth (39) that follow the crushing disc (28) to make circular motion can crush the roadbed, thereby achieving rapid crushing of the roadbed. The crushed roadbed sand and gravel will fall on the rotating ring cutter (15) and cutter holder (14). At this time, the roadbed sand and gravel can undergo centrifugal motion under the rotation of the ring cutter (15) and cutter holder (14), and be scattered on the highway roadbed.
