The cabinet 2 is fixed on the base 1, and a control panel 4 and a cabinet door 5 are provided on the front side of the cabinet 2. The control panel 4 is used to operate the entire test process, providing a user-friendly interactive experience. The setting of the cabinet door 5 facilitates the maintenance of the internal components of the device. The bottom of the base 1 near the four corners is equipped with moving wheels 3 to facilitate the movement of the device. A horizontal plate 6 is provided on the upper side of the interior of the cabinet 2, and battery modules 7 are provided on both sides of the top of the horizontal plate 6. The battery module 7 is used to provide power support for the device to ensure that testing can be carried out without an external power supply. According to actual use requirements, solar panels can be added to the present device to power the battery module 7. The bottom of the horizontal plate 6 is connected to a support plate 11 through a lifting mechanism, and a top plate 12 and a detection mechanism are provided below the support plate 11.
[0026] In this embodiment, the detection mechanism consists of a suppressor 14, a detector 15, and a pressure sensor 16. The suppressor 14 is located below the support plate 11, and the detector 15 is located below the suppressor 14. Pressure sensors 16 are located at both ends of the detector 15. The suppressor 14 is a compacting block, and the detector 15 serves as a mounting support for the pressure sensor 16. Together, they achieve the detection function.
[0027] In this embodiment, the lifting mechanism consists of a drive motor 8, a threaded rod 9 and a sliding sleeve 10. The threaded rod 9 is vertically arranged inside the cabinet 2. The lower end of the threaded rod 9 is rotatably connected to the base 1 through a bearing. The drive motor 8 is installed on the horizontal plate 6, and the output end of the drive motor 8 is fixedly connected to the upper end of the threaded rod 9. The sliding sleeve 10 is sleeved on the threaded rod 9, and the sliding sleeve 10 is screwed together with the threaded rod 9 through a thread.
[0028] In this embodiment, four groups of support plates 11 are provided, and the four groups of support plates 11 are symmetrically arranged inside the cabinet 2, and the inner ends of the support plates 11 are fixedly connected to the sliding sleeve 10, and the lower side of each group of support plates 11 is provided with a top plate 12 and a detection mechanism.
[0029] In this embodiment, a guide support rod 17 is provided through the support plate 11 near the outer end, and the support plate 11 is slidably connected to the guide support rod 17. The upper end of the guide support rod 17 is fixedly connected to the cross plate 6, and the lower end thereof is fixedly connected to the base 1, providing a guiding function for the support plate 11, ensuring its linear motion during the lifting process, avoiding lateral displacement of the support plate 11 during the lifting process, improving the accuracy and stability of the lifting mechanism, and ensuring the accuracy of the test results.
[0030] In this embodiment, a buffer 20 is provided on the upper side of each set of support plates 11 to reduce the impact and vibration during the lifting process and ensure the stability of the device.

The device is moved to the designated position by the moving wheel 3, and the roadbed filler is tested. The drive motor 8 is started, and the drive motor 8 drives the threaded rod 9 to rotate, thereby causing the sliding sleeve 10 and the support plate 11 to rise and fall. During the process of the support plate 11 and the top plate 12 falling, the roadbed filler can be subjected to multiple impact tests. At the same time, through the cooperation of the suppressor 14 and the detector 15, the detection data of the device is recorded and collected, and displayed on the display screen of the control panel 4. The strength coefficient can be calculated by the scale 21 on the top plate 12, and the detection data can be verified and measured to ensure the accuracy of the detection data. In addition, the roadbed filler can be tested at multiple locations at the same time, thereby improving work efficiency. The detection value of the sensor is displayed on the display screen of the control panel, which is a commonly used technology in the prior art. Technicians in the relevant field can complete the settings according to the prior art.
