[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0029] In the following description, the "left", "right", "front", "rear", "upper", and "lower" mentioned are oriented in the perspective direction of the front view.

[0030] In some embodiments, please refer to the attached Figures 1-5 description, an ultrasonic mixing device for uniform mixing, including a device main body 1 for placing a sample to be tested. A feeding assembly 2 is provided on the right side of the device main body 1, and a vibration mixing mechanism 3 for mixing the sample to be tested is installed at the rear end of the device main body 1;

[0031] The vibration mixing mechanism 3 includes a support frame 31, a double-headed synchronous cylinder 32, an ultrasonic vibration rod 33, a pressure rod 34, and a through hole 35. The double-headed synchronous cylinder 32 is fixedly installed at the rear side of the support frame 31. The upper output end of the double-headed synchronous cylinder 32 is fixedly connected to the pressure rod 34, and the lower output end of the double-headed synchronous cylinder 32 is fixedly connected to the ultrasonic vibration rod 33. The through hole 35 is directly above the output end of the ultrasonic vibration rod 33. The support frame 31 is connected to the device main body 1, and the through hole 35 is opened on the device main body 1.

[0032] When the present utility model is in use, a conveyor belt conveys the test tube to be tested to the device main body 1. The feeding assembly 2 sends the test tube to the mixing position. When the device main body 1 conveys the test tube to the lower end of the pressure rod 34, the double-headed synchronous cylinder 32 is started. The two output ends of the double-headed synchronous cylinder 32 simultaneously drive the ultrasonic vibration rod 33 and the pressure rod 34 to clamp the test tube. The output end of the ultrasonic vibration rod 33 faces the lower end of the test tube, and the ultrasonic vibration rod 33 uniformly mixes the liquid in the test tube;

[0033] The present utility model realizes the function of convenient feeding when facing a large number of samples to be tested, eliminating the cumbersome manual feeding. Moreover, the present utility model continuously mixes each sample to be tested through the ultrasonic vibration rod 33, preventing the phenomenon of omission or uneven mixing when multiple samples to be tested are mixed together.

[0034] In some embodiments, such as Figures 1-5As shown in the figure, as a preferred embodiment of the present utility model, the device body 1 includes a support table 11, a bump divider 12, a turntable 13, a placement groove 14, and an arc track 15. The bump divider 12 is fixedly installed at the upper end of the support table 11, and the output end of the bump divider 12 is fixedly connected to the turntable 13. A plurality of placement grooves 14 are equidistantly arranged and are all opened on the turntable 13. The plurality of placement grooves 14 are arranged in a circular pattern on the turntable 13. The arc track 15 is fixedly installed at the upper end of the support table 11. The support frame 31 is fixedly installed at the rear side of the support table 11. The through hole 35 is opened on the support table 11 and the through hole 35 is located in the arc track 15.

[0035] The arc track 15 includes a first track and a second track. The first track is located inside the support table 11, and the second track is located at the left edge of the support table 11. The left end of the first track is smoothly connected to the right end of the second track. Both the first track and the second track are arc-shaped, and the curvature of the second track is greater than that of the first track.

[0036] The feeding assembly 2 includes a support seat 21, a fixed cylinder 22, a cylinder 23, a connecting rod 24, a bump 25, an arc groove 26, and a rotating rod 27. The support seat 21 is located on the right side of the support table 11. The upper end of the support seat 21 is fixedly connected to the fixed cylinder 22. The cylinder 23 is fixedly installed at the lower end of the support seat 21. The output end of the cylinder 23 is rotatably connected to the lower end of the connecting rod 24. The bump 25 is fixedly installed on the side wall of the connecting rod 24. The arc groove 26 is opened on the side wall of the fixed cylinder 22 and the bump 25 is slidably connected to the arc groove 26 in a limiting manner. The connecting rod 24 is slidably connected to the inside of the fixed cylinder 22. The rotating rod 27 is fixedly installed at the upper end of the connecting rod 24, and the rotating rod 27 is used to push the test tube into the placement groove 14.

[0037] The bump 25 is cylindrical.

[0038] The arc groove 26 is a curved groove. The curved groove causes the connecting rod 24 to rotate to the right while moving upward, and the connecting rod 24 to rotate to the left while moving downward.

[0039] When the utility model is in use, the conveyor belt clamps the head of the test tube to be tested and conveys the test tube to be tested to the support seat 21. The air cylinder 23 is started, and the output end of the air cylinder 23 pushes the connecting rod 24 to move upward. While the connecting rod 24 is moving upward, the connecting rod 24 drives the convex block 25 to slide in the arc-shaped groove 26. Since the arc-shaped groove 26 is a curved groove, the convex block 25 will shift in position in the arc-shaped groove 26. Then the convex block 25 will drive the connecting rod 24 to rotate. Thus, while moving upward, the connecting rod 24 rotates to the right, and then the connecting rod 24 will avoid the test tube to be tested and rotate to the right side of the test tube to be tested. Then the air cylinder 23 resets, and the air cylinder 23 will drive the connecting rod 24 to move downward. Under the action of the arc-shaped groove 26, the connecting rod 24 rotates to the left and contacts the test tube to be tested, and then pushes the test tube to be tested into the placement groove 14 facing the conveyor belt;

[0040] The test tube to be tested enters the first track on the right side of the arc-shaped track 15 to prevent the test tube from shifting when the turntable 13 rotates. The cam divider 12 drives the turntable 13 to move, and the placement groove 14 moves accordingly. The placement groove 14 drives the test tube to slide in the arc-shaped track 15. When the test tube moves below the pressure rod 34, the double-headed synchronous air cylinder 32 is started. The lower output end of the double-headed synchronous air cylinder 32 drives the ultrasonic vibration rod 33 to move upward. The output end of the ultrasonic vibration rod 33 contacts the lower end of the test tube through the through hole 35. At the same time, the upper output end of the double-headed synchronous air cylinder 32 drives the pressure rod 34 to contact the upper end of the test tube. The ultrasonic vibration rod 33 and the pressure rod 34 clamp the test tube, and the ultrasonic vibration rod 33 is started to uniformly mix the liquid in the test tube. After mixing, the double-headed synchronous air cylinder 32 resets, and the cam divider 12 continues to drive the turntable 13 to rotate. The placement groove 14 drives the first mixed test tube to slide from the first track to the second track;

[0041] The second test tube to be tested moves to the upper end of the ultrasonic vibration rod 33 in the first track. After the ultrasonic vibration rod 33 vibrates and mixes it, the cam divider 12 continues to drive the second mixed test tube to rotate to the position of the first mixed test tube and thus push the first mixed test tube outwards. In this way, multiple mixed test tubes are arranged at the second track after mixing, and then the mixed test tubes are pushed into the collection box to complete the blanking.

[0042] The utility model realizes the function of convenient feeding when facing a large number of test tubes to be tested through the cooperation of the conveyor belt, the air cylinder 23, the fixed cylinder 22, the connecting rod 24, the convex block 25, the arc-shaped groove 26, and the rotating rod 27;

[0043] The utility model realizes the function of separately mixing the test tubes to be tested and preventing the omission of the test tubes to be tested through the cooperation of the cam divider 12, the turntable 13, the placement groove 14, and the arc-shaped track 15.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
