[0026] The internal dimension structure of the fastening mounting ring 7 is consistent with the external dimension structure of the sand filling tube 8, and the fastening column 6 is symmetrically installed on the left and right sides of the fastening mounting ring 7, the outer surface of the valve mounting plate 12 is tightly fitted with the inner surface of the protective pad 13, and the central axis of the valve mounting plate 12 is 90 degrees with the central axis of the protective pad 13, and the transmission motor 15 forms a rotating structure with the valve mounting plate 12 through the rotating rod 14, and the central axis of the rotating rod 14 coincides with the central axis of the valve mounting plate 12;

[0027] Specifically, Figure 1 and Figure 5 As shown, when the mechanism is used, first, by setting the limited cavity 11, the valve mounting plate 12, the protective pad 13 and the rotating rod 14, the transmission motor 15 makes the rotating rod 14 rotate, thereby driving the valve mounting plate 12 to rotate in the sand filling cylinder 8.

It greatly reduces the labor intensity of the staff and improves the efficiency of measuring the compaction degree of the roadbed.

[0031] Working principle: When the utility model is in use, first place the stable mounting plate 1 on a flat road surface, take out the hammer after placing it, and use the hammer to drive the limit pin 5 into the ground to fix the stable mounting plate 1 to prevent the stable mounting plate 1 from shifting.

Connect the external power supply of the gravity detector 18 and the LCD display 10, and control the gravity detector 18 and the LCD display 10 to start, and pour the sand to be measured from the top opening of the sand filling tube 8. The sand in the sand filling tube 8 can flow into the dug pit through the sand guide groove 16 and the fixed groove 2 in the stable mounting plate 1. Gravity The detector 18 can transmit the gravity felt in the cylindrical tube 17 to the liquid crystal display 10 in the form of an electrical signal, and the liquid crystal display 10 can display the weight in digital form, which can facilitate the staff to record the total weight of the sand. When the sand in the pit is almost filled, the transmission motor 15 causes the rotating rod 14 to rotate, thereby driving the valve mounting plate 12 to rotate in the sand filling cylinder 8. When the valve mounting plate 12 is rotated into the limiting cavity 11, the protective pad 13 on the outer surface of the valve mounting plate 12 contacts the limiting cavity 11 to form a closed space, so that no sand is discharged from the sand filling cylinder 8. When the pit is filled, the weight of the remaining sand in the sand filling cylinder 8 is measured, and the weight of the sand in the pit can be measured. This is the working principle of the roadbed compaction detection equipment for highway engineering.
