[0027] The utility model provides an extraction reagent mixing device, including an outer frame 1, a hollow column 2 is rotatably connected to the top of the outer frame 1, a column 3 is slidably connected to the hollow column 2, a plurality of storage grooves 4 for accommodating reagent tubes are provided in the column 3, a cover plate 20 is threadedly connected to the top of the column 3, a first annular plate 5 is fixed to the outside of the top of the hollow column 2, a second annular plate 6 is fixed to the outside of the column 3, a plurality of limit rods 7 are fixed at equal intervals on the top of the first annular plate 5, and the limit rods 7 penetrate the second annular plate 6 and are slidably connected to the second annular plate 6, a primary control component for driving the column 3 to rotate horizontally is arranged in the outer frame 1, and a secondary control component for driving the column 3 to move up and down is also arranged in the outer frame 1.
[0028] Among them, the primary control component includes a driven wheel 9 fixed to the outside of the hollow column 2, a driving wheel 10 is arranged in the outer frame 1, a first motor 12 is installed on the top of the outer frame 1, the output end of the first motor 12 is fixed to the driving wheel 10, and the driving wheel 10 and the driven wheel 9 are driven by a belt 11.
[0029] When in use, the reagent is injected into the reagent tube, and after the reagent tube is sealed, the reagent tube is placed in the storage groove 4, and then the cover plate 20 is rotated to thread the cover plate 20 and the column 3, and then the first motor 12 is started to drive the driving wheel 10 to rotate. When the driving wheel 10 rotates, it drives the driven wheel 9 to rotate through the belt 11. When the driven wheel 9 rotates, it drives the hollow column 2 and the column 3 to rotate, so that the column 3 can rotate horizontally, thereby mixing the reagent in the reagent tube.
[0030] In addition, a partition 13 is fixed to the inner wall of the outer frame 1, and a cylindrical block 21 is rotatably connected to the bottom of the column 3 through a bearing. A rectangular plate 14 is fixed to the bottom of the cylindrical block 21, and the rectangular plate 14 penetrates the partition 13 and is slidably connected to the partition 13. A support plate 16 is fixed to the inner wall of the outer frame 1, and a second motor 17 is installed on the support plate 16. The secondary control component includes a connecting shaft 19 fixed to the output end of the second motor 17, and a deflection wheel 18 is fixed to the end of the connecting shaft 19 away from the second motor 17, and an arc plate 15 is fixed to the bottom of the rectangular plate 14.
[0031] When in use, start the second motor 17 to drive the connecting shaft 19 to rotate, and when the connecting shaft 19 rotates, it drives the deflection wheel 18 to rotate. When the deflection wheel 18 rotates to squeeze the arc plate 15, it will drive the arc plate 15 to move upward. When the arc plate 15 moves upward, it drives the cylindrical block 21 and the column 3 to move upward. When the deflection wheel 18 no longer squeezes the arc plate 15, under the action of the gravity of the column 3, the column 3, the rectangular plate 14, and the arc plate 15 move downward, that is, the column 3 moves back and forth up and down, so that the reagent tube moves in another direction, which promotes the mixing of the reagents in the reagent tube.
[0032] In addition, springs 8 are sleeved on the outer sides of the plurality of limit rods 7. It should be noted that, due to the setting of the springs 8, when the deflection wheel 18 rotates to no longer squeeze the arc plate 15, the column 3 moves downward under the action of gravity and drives the second annular plate 6 to squeeze the spring 8, and the spring 8 will rebound after being compressed, thereby driving the column 3 to vibrate slightly up and down, further mixing the reagents in the reagent tube.
[0033] It should be noted that, since the cylindrical block 21 and the column 3 are rotationally connected via a bearing, when the rectangular plate 14 moves upward, the cylindrical block 21 and the column 3 are still rotating, so that the lateral rotation and longitudinal movement of the column 3 are not mutually exclusive.

However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
