[0039] See also Figures 1 to 4In one embodiment, the notching mechanism 20 further includes a lifting assembly and a rotating assembly; the mounting frame 101 is slidably arranged on the first frame 10 in a vertical direction, the lifting assembly is arranged on the first frame 10 and is connected to the mounting frame 101, and the lifting assembly is adjusted to drive the mounting frame 101 to slide, the tooth plate 203 is rotatably arranged on the first frame 10, the rotating assembly is arranged on the first frame 10 and is connected to the tooth plate 203, and the rotating assembly is adjusted to drive the tooth plate 203 to rotate.

[0041] In the above embodiment, the first electric telescopic rod 202 is driven to extend and the mounting frame 101 is driven to move downward, and the mounting frame 101 moves downward and drives the cutter wheel 201 to move downward. The downward movement of the cutter wheel 201 can increase the depth of the cutter wheel 201 cutting the slope soil. At the same time, the worm 207 is rotated to engage with the worm wheel 208 to drive the worm wheel 208 to rotate clockwise. The clockwise rotation of the worm wheel 208 drives the tooth plate 203 to rotate clockwise through the rotating shaft. The clockwise rotation of the tooth plate 203 can increase the depth of the tooth plate 203 inserted into the slope soil near the cutter wheel 201. By increasing the depth of the cutter wheel 201 cutting the slope soil and the tooth plate 203 inserting into the slope The depth of the soil can increase the depth of the device in the slope groove. Conversely, the depth of the slope groove cut by the cutter wheel 201 can be reduced by driving the first electric telescopic rod 202 to contract and the depth of the cutter wheel 201 cutting the slope soil can be reduced by rotating the worm 207 in the opposite direction to rotate the tooth plate 203 counterclockwise to reduce the depth of the tooth plate 203 inserted into the slope soil. The depth of the groove cut by the device in the slope can be reduced, which is convenient for adjusting the groove depth of the device according to needs and improving the practicality of the device. At the same time, when the tooth plate 203 rotates counterclockwise so that the side of the tooth plate 203 away from the cutter wheel 201 is lower than the side of the tooth plate 203 close to the cutter wheel 201, it is convenient to backfill the slope soil on the tooth plate 203 into the processed groove, and backfilling is convenient.

By providing the grille 209, during backfilling, the slope soil on the tooth plate 203 falls into the processed groove through the multiple gaps on the grille 209. At this time, the grille 209 can improve the uniformity of the slope soil backfilling, thereby improving the slope soil backfilling efficiency.

[0043] The specific implementation of the above-mentioned slope roadbed auxiliary prefabricated block paving device is as follows:

[0044] When the external power equipment pulls the first frame 10 to walk on the slope, by starting the motor 204, the motor 204 rotates and cooperates with the sprocket 206 and the chain 205 to drive the cutter wheel 201 to rotate. At this time, the cutter wheel 201 can cut the slope soil. While cutting, the tooth plate 203 moves to shovel the cut slope soil and make the shoveled soil located on the tooth plate 203, thereby completing the groove carving operation. The slope groove carving is convenient and labor-saving. When the groove carving is completed, the second frame 30 moves with the first frame 10. When the second frame 30 moves to make the laying slide rail 401 move into the processed groove, by controlling the second motor The movable telescopic rod 402 extends and drives the laying slide rail 401 to move downward. When the laying slide rail 401 moves downward to contact the bottom surface of the machined groove, the construction personnel can take the prefabricated blocks from the loading bucket 2031 and place the prefabricated blocks on the laying slide rail 401 as required. When the second frame 30 continues to move with the first frame 10, the second frame 30 drives the laying slide rail 401 to move, so that the laying slide rail 401 can be pulled out from under the prefabricated blocks, so that the prefabricated blocks can be laid in the groove. The laying of prefabricated blocks is convenient and labor-saving, which makes it easy to carry out slope grooving and prefabricated block laying at the same time, reducing the labor intensity of workers and improving construction efficiency.

[0045] When the groove depth of the device needs to be adjusted, the first electric telescopic rod 202 is driven to extend to drive the mounting frame 101 to move downward, and the mounting frame 101 moves downward to drive the cutter wheel 201 to move downward. The downward movement of the cutter wheel 201 can increase the depth of the cutter wheel 201 cutting the slope soil. At the same time, the worm 207 is rotated to engage with the worm wheel 208 to drive the worm wheel 208 to rotate clockwise. The clockwise rotation of the worm wheel 208 drives the tooth plate 203 to rotate clockwise through the rotating shaft. The clockwise rotation of the tooth plate 203 can increase the tooth plate 203 close to the cutter The depth of one side of the wheel 201 inserted into the slope soil can increase the depth of the cutter wheel 201 cutting the slope soil and the depth of the tooth plate 203 inserted into the slope soil, and the depth of the device carving grooves on the slope can be increased. Conversely, the depth of the cutter wheel 201 cutting the slope soil can be reduced by driving the first electric telescopic rod 202 to contract and the depth of the tooth plate 203 inserted into the slope soil can be reduced by rotating the worm 207 in the opposite direction to rotate the tooth plate 203 counterclockwise. The depth of the device carving grooves on the slope is convenient to adjust the groove depth of the device according to needs, thereby improving the practicality of the device.

[0046] During backfilling, the first frame 10 is pulled to the top of the prefabricated block by an external power device, and then the worm 207 is rotated to rotate the tooth plate 203 counterclockwise. When the tooth plate 203 rotates counterclockwise so that the side of the tooth plate 203 away from the cutter wheel 201 is lower than the side of the tooth plate 203 close to the cutter wheel 201, the slope soil of the tooth plate 203 can fall into the processed groove through the multiple gaps on the grid 209, thereby performing backfilling operations after the prefabricated blocks are laid.
