[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] See also Figures 1 - 3 The utility model provides a technical solution: a plant quarantine sample extraction device, comprising a bottom plate 1, and a rotating disk 2 is rotatably arranged on the upper end surface of the bottom plate 1.

[0021] Specifically, a rotation groove is provided on the upper end surface of the bottom plate 1. The rotating disk 2 is rotatably installed in the rotation groove. A plurality of shifting plates 10 are evenly fixed to the outer side of the rotating disk 2. The arrangement of the shifting plates 10 facilitates the rotating disk 2 to rotate.

[0022] The upper end surface of the rotating disk 2 is evenly provided with a plurality of limiting grooves in an annular shape. Test tubes 3 are placed inside the limiting grooves. Support frames 4 are fixedly installed on both the front and rear sides of the upper end surface of the bottom plate 1. Mixing tanks 5 are fixedly installed on the tops of the two support frames 4. The upper end surface of the mixing tank 5 is connected with a rectangular feed pipe 6 and a liquid inlet pipe 7, and a mixing assembly is arranged on the mixing tank 5.

[0023] The mixing assembly includes a rotating tube 13. The rotating tube 13 is rotatably mounted on the center position of the upper end surface of the mixing tank 5. A rotating rod 15 is rotatably mounted inside the rotating tube 13. The bottom end of the rotating tube 13 extends to the vertical middle position inside the mixing tank 5. The bottom end of the rotating rod 15 is rotatably connected to the inner bottom surface of the mixing tank 5. The upper end of the rotating rod 15 passes through the rotating tube 13 and extends above the rotating tube 13. A stirring member 17 is fixedly mounted on the outer sides of the bottom ends of the rotating tube 13 and the rotating rod 15. A driving assembly is provided on the upper end surface of the mixing tank 5.

[0024] Furthermore, the stirring member 17 includes a fixing block 18 and three stirring blades 19 evenly fixed to the outside of the fixing block 18 .

[0025] Further, the driving assembly includes a motor 11. The motor 11 is fixedly mounted on the upper end surface of the mixing tank 5. A first bevel gear 12 is fixedly connected to the output shaft of the motor 11. A second bevel gear 14 is fixedly connected to the outer side of the top end of the rotating tube 13. The second bevel gear 14 is meshedly connected with the first bevel gear 12. A third bevel gear 16 is fixedly mounted on the top end of the rotating rod 15. The third bevel gear 16 is meshedly connected with the first bevel gear 12.

[0026] The lower end surface of the mixing tank 5 is fixedly connected with a discharge pipe 8. A valve 9 is installed on the discharge pipe 8.

The test tube 3 passes under the discharge pipe 8 during the rotation process.

[0027] Working principle:

[0028] When in use, the plants and solutions to be sampled are introduced into the interior of the mixing tank 5 through the rectangular feed tube 6 and the liquid inlet tube 7. The motor 11 is started, and the output shaft of the motor 11 rotates to drive the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 drives the second bevel gear 14 and the third bevel gear 16 to rotate. And the rotation directions of the second bevel gear 14 and the third bevel gear 16 are opposite. The rotation of the second bevel gear 14 drives the rotating tube 13 to rotate. The rotation of the rotating tube 13 drives the stirring piece 17 at the bottom end of the rotating tube 13 to rotate. The rotation of the third bevel gear 16 drives the rotating rod 15 to rotate. The rotation of the rotating rod 15 drives the stirring piece 17 at the bottom end of the rotating rod 15 to rotate. Thereby, the two stirring pieces 17 rotate in opposite directions inside the mixing tank 5. Thereby, the mixing efficiency of the plants and solutions to be sampled is improved.

[0029] After the mixing is completed, the valve 9 is opened, so that the mixed solution passes through the discharge pipe 8 and falls into the test tube 3. By controlling the valve 9 and cooperating with the toggle plate 10, the rotating disk 2 rotates on the upper end surface of the bottom plate 1, thereby driving the multiple test tubes 3 to rotate, so that the multiple test tubes 3 sequentially receive the mixed solution, which saves time and labor and improves work efficiency.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
