[0023] As shown in Figure 2 , Figure 3 and Figure 7 , the up-and-down vibration mechanism comprises a first servo motor 5, a first motor bracket 6, a ball head 7, a cam 8, a connecting piece 18 and a support block 20. The inside bottom of the shell 1 is provided with the first motor bracket 6, and the first motor bracket 6 is provided with the first servo motor 5. The rotating shaft 13 of the first servo motor 5 is connected with the cam 8. Three support blocks 20 are slidably connected in the sleeve 10. The connecting piece 18 in the shape of a rod is connected between the two support blocks 20 in the middle and below. The spring 19 is connected between the two support blocks 20 in the middle and above. The spring 19 absorbs impact energy during the vibration process, which helps to reduce the hard collision between the support block 20 and the measuring cylinder 3, protects the instrument from damage, and the bottom of the connecting piece 18 below is provided with the ball head 7 made of nylon material. Nylon has good wear resistance, which can keep the ball head 7 in shape and function during long-term high-frequency vibration, reducing the frequency of maintenance and replacement. The ball head 7 penetrates the bottom of the sleeve 10 through the circular hole 1001, and the ball head 7 is located directly above the cam 8 and can contact the cam 8.

After placing the measuring cylinder 3 in the sleeve 10 through the through hole of the shell 1, screw the fixed cover 9 back onto the threaded groove at the top of the sleeve 10. Then start the first servo motor 5, which drives the cam 8 to rotate clockwise. When the farthest end of the cam 8 rotates away from the ball head 7, the measuring cylinder 3 moves downward together with the support block 20 under the action of gravity. The cam 8 continues to rotate, and the farthest end of the cam 8 will rotate to the bottom of the ball head 7. The ball head 7 drives the support block 20 and the measuring cylinder 3 to move upward, thus completing one up-and-down vibration. After a certain period of up-and-down vibration, start the second servo motor 11, which drives the rotating disc 14 to rotate. The rotating disc 14 rotates with the sliding block 15. The sliding block 15 oscillates left and right through the rectangular hole to the guide seat 16 with the rotating shaft 13 as the axis, achieving better compaction effect and improving the accuracy of measurement. After a certain period of left-and-right oscillation, turn off the second servo motor 11, unscrew the fixed cover 9, and take out the measuring cylinder 3 from the sleeve 10.

[0027] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
