The rotation of the rotating sleeve is transmitted to the stirring drum via a spline shaft, causing it to rotate inside the culture tank to achieve the stirring function. At the same time, the cylindrical cam on the top output shaft of the dual-shaft motor rotates, and through the sliding connection between the slide groove and the connecting ball, it drives the transmission rod to move up and down, causing the stirring drum to achieve lifting and lowering motion. This can break the stratification phenomenon in the sample, so that the samples of different layers are fully mixed, further improving the extraction effect and achieving the advantage of high extraction uniformity.

[0019] 2. This yeast production sample deep extraction device, when the booster pump is started, draws cleaning solution from the water tank and delivers it to the bushing through a hose. The cleaning solution enters the spline shaft through the bushing and is sprayed into the culture tank through the nozzles on the spline shaft. At the same time, the rotation of the stirring drum helps to distribute the cleaning solution evenly, so that the cleaning solution can be evenly sprayed to all corners of the culture tank, ensuring thorough cleaning and achieving the advantage of easy cleaning.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This embodiment of a yeast production sample deep extraction device includes a culture tank 1, a sealing cover 2 detachably connected to the top of the culture tank 1, a feed hopper 3 fixedly connected to the top of the sealing cover 2, and a base 4 fixedly connected to the bottom of the culture tank 1. The top of the sealing cover 2 is provided with a stirring mechanism for stirring the yeast sample, and the base 4 is provided with a cleaning mechanism extending into the interior of the culture tank 1. The stirring mechanism includes a mounting base 5 fixedly connected to the top of the sealing cover 2 and a rotating sleeve 10 rotatably connected to the upper surface of the sealing cover 2 and extending into its interior. A dual-axis motor 6 is fixedly installed on the inner wall of the mounting base 5, and a transmission gear 7 is fixedly connected to the output shaft at the bottom end of the dual-axis motor 6. A driven gear 9 is fixedly connected to the outside of the rotating sleeve 10. A spline shaft 11 extending into the interior of the culture tank 1 is slidably connected inside the rotating sleeve 10. A stirring cylinder 8 is fixedly connected to the outside of the spline shaft 11. A lifting structure for the spline shaft 11 is provided outside the mounting base 5.

[0027] The dual-axis motor 6 is fixedly mounted inside the mounting base 5 via a motor mount. The transmission gear 7 and the driven gear 9 mesh with each other. The stirring drum 8 is rotatably connected inside the culture tank 1, and the outer diameter of the stirring drum 8 is adapted to the inner diameter of the culture tank 1. The lifting structure includes a cylindrical cam 12 fixedly connected to the top output shaft of the dual-axis motor 6 and a bearing 13 fixedly mounted outside the spline shaft 11. A connecting sleeve 14 is fixedly connected to the outside of the bearing 13, and a transmission rod 16 is fixedly connected to the left side of the connecting sleeve 14.

[0028] Specifically, the end of the transmission rod 16 away from the connecting sleeve 14 is fixedly connected to a connecting ball 17 extending into the inside of the cylindrical cam 12. The inside of the cylindrical cam 12 is provided with a sliding groove 15 that is adapted to the connecting ball 17, and the connecting ball 17 and the sliding groove 15 are slidably connected.

[0029] It should be noted that the interior of the stirring tube 8 has several through holes, which are distributed at equal intervals inside the stirring tube 8. A fixing rod 18 is fixedly connected to the right side of the connecting sleeve 14. A limiting sleeve 19 is fixedly connected to the end of the fixing rod 18 away from the connecting sleeve 14. A limiting rod 20 is fixedly connected to the top of the sealing cover 2. The limiting sleeve 19 is slidably connected to the outside of the limiting rod 20. When the dual-axis motor 6 is started, its bottom output shaft drives the driven gear 9 to rotate through the transmission gear 7, which in turn drives the rotating sleeve 10 to rotate. The rotation of the rotating sleeve 10 is transmitted to the stirring tube 8 through the spline shaft 11, so that it rotates inside the culture tank 1 to achieve the stirring function. At the same time, the cylindrical cam 12 on the top output shaft of the dual-axis motor 6 rotates and drives the transmission rod 16 to move up and down through the sliding groove 15 and the connecting ball 17, so as to drive the stirring tube 8 to achieve the lifting and lowering motion, which can break the stratification phenomenon in the sample and make the samples of different layers fully mixed.

[0030] Please see Figures 1 to 3 In this embodiment, the cleaning mechanism includes a water tank 21 fixedly installed inside the base 4, a booster pump 22 fixedly installed outside the base 4, and a hose 24 fixedly connected to the output end of the booster pump 22.

[0031] The splined shaft 11 is rotatably connected to a bushing 23 at its top end. The end of the hose 24 away from the booster pump 22 is fixedly connected to the bushing 23. A water pump 22 is fixedly connected to the water tank 21 via a water pipe. The splined shaft 11 has several spray holes inside. When the booster pump 22 is started, it draws cleaning fluid from the water tank 21 and delivers it to the bushing 23 through the hose 24. The cleaning fluid enters the interior of the splined shaft 11 through the bushing 23 and is sprayed into the culture tank 1 through the spray holes on the splined shaft 11. At the same time, the rotation of the stirring drum 8 helps to distribute the cleaning fluid evenly, so that the cleaning fluid can be evenly sprayed to all corners of the culture tank 1.

[0032] Specifically, a sampling tube is fixedly connected to the outside of the culture tank 1, a sampling valve is fixedly installed inside the sampling tube, and a drain pipe is fixedly connected to the outside of the culture tank 1.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the sample is added to the culture tank 1 through the feed hopper 3. The dual-shaft motor 6 is started by the controller, causing its bottom output shaft to drive the driven gear 9 to rotate via the transmission gear 7. This, in turn, drives the rotating sleeve 10 to rotate. The rotation of the rotating sleeve 10 is transmitted to the stirring drum 8 via the spline shaft 11, causing it to rotate inside the culture tank 1 to achieve the stirring function. At the same time, the cylindrical cam 12 on the top output shaft of the dual-shaft motor 6 rotates, and through the sliding connection of the slide groove 15 and the connecting ball 17, it drives the transmission rod 16 to move up and down, thereby causing the stirring drum 8 to rise. Under the stirring and lifting action of the stirring drum 8, the sample is fully mixed in the culture tank 1. When sampling is required, the sampling valve is opened and the sample can flow out through the sampling tube. When the booster pump 22 is started, the cleaning solution is drawn from the water tank 21 and delivered to the bushing 23 through the hose 24. The cleaning solution in the hose 24 enters the interior of the spline shaft 11 through the bushing 23. The cleaning solution is sprayed into the interior of the culture tank 1 through the spray hole inside the spline shaft 11 to clean the culture tank 1. After cleaning, the drain pipe valve is opened to discharge the cleaning waste liquid.
