When compression roller 7 met the position of unevenness, compression roller 7 drove sliding seat 72 and compressed buffer spring 73, and buffer spring 73 had elastic restoring force by the compression to buffer spring 73 cushions the energy-absorbing to compression roller 7 under the effect of elastic restoring force, stability when increasing compression roller 7 and removing, and then be convenient for compression roller 7 and the abundant laminating of filling layer.

The application principle of the creek pond mucky soil backfilling rubble soil construction equipment in the embodiment of the application is as follows: an operator pours the gravel soil after proportioning into the mixing drum 1 through the loader, so that the first motor 23 drives the stirring shaft 21 to drive the stirring rod 22 to stir the gravel soil. At this time, the driving shaft 25 drives the stirring blade 26 to rotate, so as to achieve the effect of further stirring the crushed soil, thereby improving the mixing uniformity of the crushed soil. The crushed soil is then discharged from the discharge port 102 into the guide cylinder 11, so that the second motor 43 drives the driven rod 42 to break up and stir the crushed soil again, thereby achieving an effect of sufficiently mixing the crushed soil. Then the gravel soil falls down on the drainage plate 51 from the guide cylinder 11, and the third motor 55 drives the drainage plate 51 to do reciprocating motion at this moment, so that the gravel soil rolls on the drainage plate 51, thereby realizing the purpose of further mixing the gravel soil, and finally the gravel soil rolls down on the substrate along the drainage plate 51 to achieve the effect of uniformly filling the gravel soil on the substrate.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
