Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices for highway engineering material tests, and more specifically, it relates to a sampling device for highway engineering material tests. Background Art

[0002] In the current field of highway engineering, the sampling device for material tests is an important tool for soil sampling, and its performance is directly related to the accuracy of sampling results and safety during use. However, there is a significant problem in the operation of existing sampling devices: if too much force is applied during sampling, it may cause damage to the internal motor of the sampling device. This problem not only affects the normal operation of the equipment, but also poses a threat to the safety of operators, thus reducing the overall safety of use.

[0003] Specifically, when using the existing sampling device for highway engineering material tests to sample soil, if the operator fails to precisely control the force, or applies excessive force in a hard soil layer, it may cause the internal motor of the sampling device to bear a force beyond its designed bearing range. Such excessive force will not only shorten the service life of the motor, but may even cause the motor to be damaged instantly, resulting in equipment failure. This not only increases the maintenance cost and downtime, but may also lead to safety accidents due to equipment failure, posing a potential risk to the life safety of operators.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a sampler for highway engineering material tests, having the following beneficial effects:

[0030] In this embodiment, when sampling is required, first press the bottom plate 23 at the corresponding position, then drive the driver 22 to slide on the guiding rod 21, so that the sampling tube 1 is inserted into the corresponding position, then drive the rotation of the sampling tube 1 by the driver 22, and then proceed with the sampling process.

When it is necessary to adjust the clamping force, first rotate the adjusting sleeve 14. Since the spiral groove 13 is engaged in the adjusting sleeve 14 and their angles are the same, the slider 7 can be driven to slide along the contraction groove 12. And the diagonal blocks 11 on the upper and lower sides are respectively connected to the adjusting sleeve 14 by reverse threads, so they can slide up and down synchronously. Since it slides in the contraction groove 12, the positions between the multiple clamping plates 4 can be changed, thereby changing the elastic force between the spring 6 and the insertion rod 2, and then the adjustment process is completed.
