[0098] The working principle of the utility model is as follows: the servo motor 9 drives the transmission rod 10 to rotate axially through the output shaft, and the first transmission wheel 11 on the transmission rod 10 rotates accordingly. The first transmission wheel 11 makes the second transmission wheel 15 rotate through the transmission belt 12, and the second transmission wheel 15 drives the rotating shaft fixed to it to rotate, and the rotating shaft drives the cam 27 to rotate. Every time the cam 27 rotates one circle, under the action of the spring 29, the moving rod 25 reciprocates up and down once.

The third piston plate presses the heated gas in the air storage box 17 into the air bag 47 through the vent pipe 46. The air bag 47 gradually increases, and the water in the separation cylinder 43 is subjected to pressure filtration. The hot air from the air bag 47 heats the sand and the water evaporates. It can be seen that the separation cylinder 43 can be centrifuged, filtered and dried simultaneously, thereby improving the separation efficiency. The separation efficiency is improved, and the accuracy of the detected sand weight is improved. The second piston plate 36 moves up and down with the moving rod 25, and the air suction cylinder 4 sucks water vapor into the air suction cylinder 4 through the air suction pipe 30. The air suction cylinder 4 then discharges the water vapor into the bottom of the detection cylinder 3 to contact with the separated water, thereby performing a cooling process to liquefy the vaporized water, so that the weight of the sampled water will not be reduced due to vaporization, which will increase the error of the detection result; after the separation is completed, the ratio of the weight weighed by the weighing sensor 49 to the weight weighed by the weighing device 2 is the sand content.
