When the hardness of the highway is detected, the generated dust and gravel are covered to avoid the dust from flying around, protect the environment, and avoid the gravel from splashing around, reducing the harm to the staff, and solving the problem that when the existing hardness detection device is used to detect the hardness of the highway, dust is scattered around to pollute the environment, and gravel splashes around to cause harm to the construction personnel.

[0004] However, the above patents still have the following shortcomings: the height of the protective mechanism needs to be manually adjusted, which is not convenient. At the same time, after the protective mechanism is used to protect the pressure head, it is not convenient to observe the actual situation of the pressure head squeezing the road surface, which affects the hardness test. In addition, when the pressure head squeezes the road surface, the bin body will be affected by the reaction force of the ground, which will affect the stability of the bin body. For this reason, we propose a hardness test device for highway construction. Utility Model Content
