Description

Technical Field

[0001] The utility model relates to the technical field of road performance detection equipment, in particular to a road water-stable base compaction sampling instrument. Background Art

[0002] The compaction degree test of water-stable base refers to a method of testing the compaction degree of road base. Water-stable base refers to the road base made of a mixture of stone, sand, cement and other materials. Its compaction degree refers to the density of the base material. By testing the compaction degree of the water-stable base, the quality of the base can be evaluated, whether it meets the design requirements, and whether further compaction treatment is required.

[0003] When testing the compaction of the road water-stable base, a special sampler is needed to take samples. In the Chinese utility model patent with the authorization announcement number CN220468811U, a water-stable base compaction rapid tester is disclosed, which is provided with a lever structure composed of an adjustment frame and a tilting rod, and the lifting plate at the other end is pulled by the swing of one end of the tilting rod to coordinate with the drilling motor to adjust, so as to complete the sampling work; although the above patent can complete the sampling operation, it changes the height of the lifting plate, the drilling motor and the drill bit by rotating the tilting rod, which will lead to The drill bit's movement trajectory is an arc instead of moving in the vertical direction, which increases the difficulty of the drill bit's sampling and reduces the drill bit's sampling efficiency. Moreover, the mechanical transmission process of the entire lever mechanism is relatively complicated, involving the threaded cooperation between the threaded sleeve and the threaded rod, the sliding cooperation between the limit block and the moving frame, and the rotation cooperation between the tilting rod and the threaded sleeve, the adjustment frame and the lifting plate. If any of these links goes wrong, the drill bit cannot move, thereby affecting the entire sampling work. Moreover, the coordination of multiple transmission methods also makes the entire instrument structure relatively complicated, occupies a large space, and is not convenient for transportation and storage.
