Description

Technical Field

[0001] The utility model relates to the technical field of compactors, in particular to a soil compactor. Background Art

[0002] In the construction of some water conservancy projects, such as dam filling, the original structure and state of the soil change due to excavation, transportation and filling. If the soil is not compacted, the porosity ratio is often large and it is difficult to meet the needs of the project. Therefore, in order to reduce the post-construction settlement of the fill and increase the strength, the project must follow certain standards and compact it through rolling, tamping or vibration.

[0003] The patent document with the announcement number CN218880796U discloses a soil compactor, including a moving frame, a universal wheel, a push rod, a first fixed rod, a connecting rod and a moving rod. Two universal wheels are symmetrically installed on the front and rear sides of the bottom of the moving frame. A push rod is fixedly connected to the rear side of the lower part of the moving frame. The front and rear sides of the upper part of the moving frame are fixedly connected to the first fixed rod. The lower end of the first fixed rod is fixedly connected to the connecting rod. Two moving rods are rotatably arranged at the right end of the connecting rod. By starting the motor, the output shaft of the motor drives the first rotating rod to rotate through the coupling, thereby rotating the first pulley assembly. The rotation of the first pulley assembly causes the moving rod to rotate downward, thereby causing the moving frame to drive the pressing plate to move downward to compact the soil, thereby achieving the effect of quickly compacting the soil.

[0004] In the prior art, during the process of compacting the soil by the pressing wheel, the pressing wheel is easily stained with a large amount of soil, which affects the working efficiency. Therefore, we propose a soil compactor to solve the above problem. Utility Model Content
