A feed port is provided at the upper end of the mixing barrel, and a sealing cover is provided on the feed port. When in use, this technical solution realizes rapid discharging through a vibrator, which is conducive to improving the discharging efficiency. An opening and closing mechanism is provided, with a good sealing effect, and the operation is time-saving and labor-saving, thereby extending the service life of the mixing device. With respect to the above technical solution, although this solution realizes rapid discharging, it is unable to quickly move the biological agent adhered to the inner wall to the outlet during use, which is inconvenient during use. Utility Model Content

The present invention has a novel structure. When in use, the rotating seat drives the barrel body to rotate, and the barrel body rotates back and forth up and down, so that the liquid inside the barrel body can flow by itself, and collides with the baffle rod during flow to be quickly mixed. In the later stage, the biological agent on the inner wall is quickly moved to the discharge pipe under the centrifugal rotation of the barrel body.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a biological reagent mixing device, comprising a base, a support seat welded on the base, a fixed seat welded on the support seat, a limiting seat fixed on the side of the fixed seat, a rotating seat rotatably installed inside the limiting seat, a barrel body fixedly installed on one side of the rotating seat, a discharge pipe fixed to the bottom of the barrel body, an opening formed on the top of the rotating seat, a counterweight seat movably installed inside the opening, a support tube fixed inside the barrel body, and an installation hole formed between the support tube and the rotating seat.

[0006] Furthermore, a support column is movably installed inside the mounting hole, a limiting hole is opened on the support column, and a threaded column is movably installed inside the limiting hole.

[0007] Furthermore, one end of the threaded column is fixed on the rotating handle, one end of the support column is fixed with a protrusion, the protrusion is movably matched with the rotating seat, and one end of the support column is fixed on the counterweight seat.

[0008] Furthermore, a blocking rod is fixed to the side of the support tube, an annular groove is opened on the rotating seat, a convex ring is movably installed inside the annular groove, and the convex ring is fixedly installed on the inner wall of the limiting seat.

[0009] Furthermore, a power mechanism is fixed on one side of the fixing seat, an output shaft is installed on the power mechanism, a driving gear is fixed to one end of the output shaft, a cavity is opened inside the fixing seat, and the driving gear is movably installed inside the cavity.

[0010] Furthermore, a driven gear is movably mounted on the side of the driving gear, a rotating column is fixed on the driven gear, and one end of the rotating column is fixed on the rotating seat.

[0011] Beneficial effects of the utility model:

[0012] 1. This biological reagent mixing device, when in use, the rotating seat drives the barrel to rotate, and the barrel rotates back and forth, so that the liquid inside the barrel can flow by itself, and collides with the baffle rod during flow to be quickly mixed. In the later stage, the centrifugal rotation of the barrel causes the biological agent on the inner wall to move quickly to the discharge pipe.

[0013] 2. In this biological reagent mixing device, the counterweight block is moved by the support column. The movement of the counterweight block cooperates with the barrel body to keep the rotating seat in a balanced state. After the forces on both sides of the rotating seat are balanced, the rotating seat can rotate quickly to avoid shaking, thereby facilitating the cleaning of the biological agent inside the barrel body.

[0022] When in use, the power mechanism 4 is started, and the power mechanism 4 drives the driven gear 14 to rotate through the driving gear 13, and the driven gear 14 drives the rotating seat 6 to rotate through the rotating column 15.
