Description

Technical Field

[0001] The present application relates to the technical field of road surface sampling equipment, and in particular to a road surface sampling device. Background Art

[0002] Road surfaces generally include cement roads and asphalt roads. After construction, both cement roads and asphalt roads need to be tested for compaction and structural layer thickness. The general testing method is to drill holes and take samples using a sampling machine.

[0003] The existing sampler includes a mounting frame and a driving mechanism arranged on the mounting frame, the driving mechanism includes a rotating motor and a driving cylinder arranged on the mounting frame, a sampling barrel with an opening is fixedly mounted on the rotating motor, the driving cylinder drives the rotating motor to move back and forth in the vertical direction, the rotating motor is used to drive the sampling barrel to rotate at high speed, when sampling, the sampling barrel is directly driven by the driving mechanism to rotate at high speed on the cement road surface or asphalt road surface, and move downward to sample the road surface. Since the core drilling machine will generate a lot of dust and heat by friction with the highway sample core during the sampling process, cooling water is directly sprayed on the outer wall of the sampling barrel through the water spray pipe to reduce the temperature and dust, thereby improving the quality of the core sample.

[0004] However, currently the cooling water is directly sprayed on the outside of the sampling tube through a water spray pipe. Due to the rotation of the sampling tube, most of the cooling water will be thrown out, which has an unsatisfactory cooling effect on the sample core inside the sampling tube. Utility Model Content

[0005] In order to better cool the interior of the sampling tube and the sample core, the present application provides a road surface sampling device.

[0006] The present application provides a road sampling device that adopts the following technical solution:

At this time, the water flowing out of the water outlet pipe will flow into the sample core and the inner wall of the sampling tube. Even if the sampling tube rotates at high speed during use, the water flowing out of the water outlet pipe is in the sampling tube and will not be thrown out. At this time, it is convenient to cool the inner wall of the sampling tube.

[0014] By adopting the above technical solution, in the initial state, one end of the push rod is flush with the end face of the opening of the sampling tube. As the sampling tube extends below the ground, the end face of the sample core will abut against the push rod. As the sampling tube moves, the push rod is pushed to move. The movement of the push rod also drives the push plate to move. The movement of the push plate drives the water in the water tank to move, thereby facilitating the water in the water tank to flow out through the outlet pipe.

[0015] Optionally, an elastic reset member is provided in the water tank for moving the push plate toward the opening of the sampling tube, one end of the elastic reset member is fixed to the push plate, and the other end is fixed to the inner wall of the water tank.

[0016] By adopting the above technical solution, when the sample core is taken out from the sampling tube, the push plate and the push plate are reset under the action of the elastic reset member, which is convenient for the next sampling.

[0017] Optionally, a water inlet hole is provided on the water storage tank, and a blocking bolt for blocking the water inlet hole is also provided on the water storage tank, and the blocking bolt is threadedly connected to the water inlet hole.

Under the action of gravity, the water sprayed toward the inner wall of the sampling tube 13 will fall onto the sample core, thereby cooling down the sample core. In other embodiments, a portion of the water outlet holes 42 can also be arranged toward the sample core, thereby facilitating cooling down the sample core and the inner wall of the sampling tube 13 at the same time. In addition, in order to improve the sealing between the water outlet pipe 4 and the water storage tank 12, a sealant is applied at the connection between the water outlet pipe 4 and the water storage tank 12.
