Technical Field

[0001] The utility model relates to the technical field of roadbed construction, in particular to a roadbed compacting device. Background Art

[0002] The main function of the roadbed compaction device is to make the soil or pavement material reach the required density, thereby improving its bearing capacity and stability. The device repeatedly compacts the soil through mechanical force to reduce the air and moisture in the soil and increase the density of the soil.

[0003] When the existing compacting device is used, when the compacting block contacts the wet soil on the ground, the surface of the compacting block is easily contaminated with soil and is inconvenient to clean. The soil on the compacting block will cause uneven soil density distribution during repeated use, thus affecting the compaction effect.

[0004] Therefore, a roadbed compacting device is needed to improve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a roadbed compacting device to solve the problems raised in the above background technology.

Connecting rods are respectively mounted in the middle of the front and rear inner walls of the vehicle body inner cavity, and pressure sensors are mounted on the bottom surfaces of the connecting rods close to the hydraulic telescopic rods. Scraping assemblies are respectively mounted on the front and rear sides of the vehicle body bottom.

[0008] The scraping assembly includes a connecting frame;

[0013] As a preferred solution of the present invention, a tamping block is commonly installed on the bottom surfaces of the two sliding rods, and the bottom ends of the two springs are respectively connected to both sides of the top surface of the tamping block.

[0014] As a preferred solution of the present invention, through grooves are symmetrically opened on the bottom surface of the vehicle body, and limit plates are respectively installed on the left and right sides of the inner cavity of the through groove, and the bottom surface of the limit plate contacts the top surface of the tamping block.

[0019] The utility model discloses a roadbed compacting device, wherein a transfer assembly, a connecting rod, a pressure sensor and a scraping assembly are arranged in a roadbed compacting device. When the soil on the bottom surface of the compacting block needs to be cleaned during use of the device, the hydraulic telescopic rod drives the transfer assembly to move upward as a whole. As the transfer assembly moves upward, the compacting block will be restricted in moving upward by the limit plate. At this time, the left and right lower compacting blocks and the limit plate are in close contact with each other. As the mounting plate rises, the mounting plate will contact the pressure sensor, and the pressure sensor will control the start of the motor. The motor will drive the threaded rod to rotate, and the moving block and the scraper on the threaded rod will move at the same time to clean the soil stuck on the bottom surface of the compacting block, thereby achieving the benefit of quickly cleaning the soil on the bottom surface of the compacting block. This solves the problem that when the compacting block of the existing compacting device contacts the wet soil with the ground during use, its surface is easily contaminated with soil and is inconvenient to clean. The soil contaminated on the compacting block will cause uneven soil density distribution during repeated use, thereby affecting the compaction effect. BRIEF DESCRIPTION OF THE DRAWINGS
