[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figure 1-10As shown, a microbial beneficial bacteria cultivation device described in the present invention includes a device body 1, a stirring structure 2, a culture medium 3, a support structure 4 and an adjustment structure 5; the device body 1 is provided with a stirring structure 2, a support structure 4 and an adjustment structure 5; the stirring structure 2 is fixedly connected to the upper inner wall of the device body 1; the support structure 4 is located in the middle of the device body 1, and the culture medium 3 is placed on the support structure 4; the adjustment structure 5 is located below the support structure 4; the device body 1 includes a device shell 11, and the inner wall of the device shell 11 is fixedly connected with a support seat 13; the device body 1 provides a closed environment for the cultivation of microorganisms, and the device body 1 is provided with a temperature control structure and a humidity control structure, which can provide a suitable cultivation environment when cultivating microorganisms. The stirring structure 2 is set, and after the inoculation is completed and the culture medium 3 is placed on the support structure 4, the stirring structure 2 can mix the microorganisms inoculated in the culture medium 3 with nutrients The culture medium 3 can be evenly mixed, and the inner side wall of the culture medium 3 can be ensured not to adhere to the microorganisms and the nutrient medium, which is convenient for the later cleaning of the culture medium 3 and the observation of the microorganisms that have been cultured by the staff; the setting of the support structure 4 can support the culture medium 3 and facilitate the adjustment of the position of the culture medium 3, so that the stirring structure 2 can be used for stirring different culture media 3, and the setting of the adjustment structure 5 can drive the support structure 4 to rotate as a whole, adjust the position of the culture medium 3, and move different culture media 3 to the bottom of the stirring structure 2, so that the stirring structure 2 can stir the microorganisms and the nutrient medium in the culture medium 3 on the support structure 4. At the same time, the adjustment structure 5 can cancel the restriction on the support structure 4, and facilitate the overall removal of the support structure 4; the device shell 11 is the main structure of the device body 1, which is convenient for the fixation of the stirring structure 2, the support structure 4 and the adjustment structure 5, and the support seat 13 set in the device shell 11 can stably support the support structure 4.

[0027] Specifically, the stirring structure 2 includes an electric push rod 21, a first motor 22, a fixing frame 23, a stirring rod 24, an outer gear 25, an inner gear 26, a mounting plate 27, a limit spring 27a, a connecting rod 28 and a mounting frame 29; the upper end of the electric push rod 21 is fixedly connected to the upper inner wall of the device housing 11, and the lower end of the electric push rod 21 is fixedly connected to the fixing frame 23 through the mounting frame 29, the upper surface of the fixing frame 23 is fixedly connected with the first motor 22, and the output shaft of the first motor 22 passes through the fixing frame 23 and is fixed A mounting plate 27 is connected, and a connecting rod 28 is slidably connected to the mounting plate 27. One end of the connecting rod 28 located outside the mounting plate 27 is fixedly connected to an external gear 25. A limit spring 27a is arranged inside the mounting plate 27. An internal gear 26 is arranged on the inner wall of the fixing frame 23. The internal gear 26 and the external gear 25 are meshed with each other. A stirring rod 24 is fixedly connected to the lower surface of the external gear 25. The electric push rod 21 is used to adjust the height of the stirring structure 2. The stirring rod 24 in the stirring structure 2 will not affect the supporting structure 4. The mounting frame 29 is arranged to facilitate the connection between the fixing frame 23 and the electric push rod 21, and reserve a certain space for the arrangement of the first motor 22; the fixing frame 23 can fix the inner gear 26, and the meshing between the outer gear 25 and the inner gear 26 enables the outer gear 25 to rotate while being driven by the first motor 22 and to revolve around the inner gear 26, so as to adjust the running track of the stirring rod 24, so that the stirring rod 24 can mix the nutrient medium and microorganisms in the culture medium 3 in a vertical state without causing the microorganisms or the nutrient medium to rotate. It sticks to the inner wall of the culture medium 3, which is convenient for the staff to clean the culture medium 3 and observe the microorganisms that have been cultured. When the outer gear 25 rotates, it will slide on the mounting plate 27 with the connecting rod 28, so that the outer gear 25 can always mesh with the inner gear 26 and revolve around. The force exerted by the limit spring 27a arranged inside the mounting plate 27 on the connecting rod 28 can ensure that the outer gear 25 will not be separated from the inner gear 26 during rotation and revolution. The limit spring 27a is arranged at one end of the mounting plate 27 close to the output shaft of the first motor 22.

[0028] Specifically, the support structure 4 includes a support frame 41, a first connecting shaft 42, a fixed seat 43, a clamping arm 44, a first spring 45, a clamping block 46 and a support plate 47; the support frame 41 is placed on the support seat 13, and the lower surface of the support frame 41 is fixedly connected to the first connecting shaft 42, the upper surface of the support frame 41 is fixedly connected to the fixed seat 43, the fixed seat 43 is distributed on the support frame 41 in an annular array, and the clamping arm 44 is rotatably connected to the fixed seat 43, the clamping arm 44 is distributed on the fixed seat 43 in an annular array, and the upper ends of the clamping arms 44 are fixedly connected to the clamping blocks 46; the interior of the fixed seat 43 is fixedly connected to the first spring 45, the upper end of the first spring 45 is fixedly connected to the support plate 47, and the lower surface of the support plate 47 is in contact with the upper surface of the lower end of the clamping arm 44; The overall structure of the support structure 4 is circular, and the central axis of the first connecting shaft 42 coincides with the central axis of the support frame 41. The fixing seat 43 facilitates the setting of the first spring 45 and the rotational connection of the clamping arm 44. When the culture medium 3 is placed on the support disk 47, the force of the support disk 47 on the first spring 45 increases, and the first spring 45 contracts. At the same time, the support disk 47 moves downward and pushes the clamping arm 44 to rotate. The upper end of the clamping arm 44 gathers toward the culture medium 3 to fix the culture medium 3, ensuring that the culture medium 3 can be in a fixed state when the support structure 4 rotates. When the stirring structure 2 mixes the microorganisms and the nutrient medium in the culture medium 3, the culture medium 3 will not rotate or move. The clamping block 46 is a rubber product, which increases the friction between the clamping arm 44 and the culture medium 3 without damaging the surface of the culture medium 3.

[0029] Specifically, the adjustment structure 5 includes a pressure rod 51, a second motor 52, a second connecting shaft 53, a second spring 54, a fixing plate 55, a bearing 56, a first fixing rod 57, a large roller 58, a second fixing rod 59 and a small roller 59a; the second motor 52 is fixedly connected to the lower inner wall of the device housing 11, and the second connecting shaft 53 is slidably connected to the output shaft of the second motor 52, and the upper end of the second connecting shaft 53 cooperates with the lower end of the first connecting shaft 42; the second spring 54 is sleeved on the output shaft of the second motor 52, and the inner diameter of the second spring 54 is larger than the inner diameter of the second connecting shaft The outer diameter of the shaft 53; the lower part of the second connecting shaft 53 is rotatably connected to a fixed plate 55 through a bearing 56, and the fixed plate 55 is symmetrically provided with a first fixed rod 57, the first fixed rod 57 is fixedly connected to the fixed plate 55, and the end of the first fixed rod 57 away from the second connecting shaft 53 is rotatably connected to a large roller 58; the second connecting shaft 53 is fixedly connected to a pressure rod 51, and the middle part of the pressure rod 51 is fixedly connected to a second fixed rod 59, the second fixed rod 59 is symmetrically arranged about the central axis of the pressure rod 51, and the end of the second fixed rod 59 away from the pressure rod 51 is rotatably connected to a small roller When the pressure rod 51 is pressed downward, the pressure rod 51 can drive the fixing plate 55 to move downward as a whole. At this time, the second fixing rod 59 arranged on the pressure rod 51 can slide in the limiting groove 11a provided on the device housing 11 through the small roller 59a to ensure that the pressure rod 51 moves vertically downward. The first fixing rod 57 arranged on the fixing plate 55 slides on the inner wall of the device housing 11 through the large roller 58 to limit the fixing plate 55 to ensure that the fixing plate 55 can only move in the vertical direction. The fixing plate 55 can limit the upper end of the second spring 54 and drive the second connecting shaft 53 to move upward. The second connecting shaft 53 is moved downward to disengage from the first connecting shaft 42, thereby canceling the restriction of the second connecting shaft 53 on the first connecting shaft 42, making it convenient for the staff to remove the supporting structure 4 as a whole, thereby improving the work efficiency of the staff; the arrangement of the bearing 56 facilitates the fixing of the fixing plate 55 without affecting the rotation of the second connecting shaft 53 driven by the output shaft of the second motor 52; a clamping block is arranged on the output shaft of the second motor 52, and a slide groove is provided at the position of the clamping block corresponding to the position on the second connecting shaft 53, and the slide groove can limit the position of the clamping block to ensure that when the second motor 52 rotates, the second connecting shaft 53 can rotate together.

[0030] Specifically, the device body 1 includes a device shell 11, a limit groove 11a, a protective door 12, a glass 12a, a handle 12b, a support seat 13, a baffle 14, a roller 15 and a ball 16; the support seat 13 is located in the middle of the device shell 11, and the support seat 13 is rotatably connected with the roller 15, the rollers 15 are arranged on the support seat 13 at equal intervals, and the rollers 15 are in contact with the edge positions of the support frame 41, and the support seat 13 is provided with balls 16 at a position below the support frame 41, and the balls 16 are evenly spaced and distributed in a circular array on the support seat 13, and the balls 16 are rollingly connected to the support seat 13; the device shell 11 The protective door 12 is rotatably connected, and the protective door 12 is symmetrically arranged about the vertical plane where the symmetry axis of the device housing 11 is located, and the protective door 12 is provided with a glass 12a and a handle 12b, and the handle 12b is fixedly connected to the corresponding protective door 12; the inner wall of the device housing 11 is provided with a baffle 14 at the positions on both sides of the large roller 58, and the inner wall of the device housing 11 is provided with a limiting groove 11a at the position corresponding to the small roller 59a; the setting of the limiting groove 11a enables the small roller 59a to roll up and down only in the vertical direction, and the angle of the pressure rod 51 on the horizontal plane is limited by the small roller 59a and the second fixing rod 59, and when the pressure rod 51 moves to When the second connecting rod 53 is moved up and down, no horizontal force will be applied to the fixed plate 55. The setting of the baffle 14 can limit the rolling trajectory of the large roller 58. The cooperation between the large roller 58 and the first fixed rod 57 can limit the angle of the fixed plate 55 in the horizontal direction. When used in conjunction with the second fixed rod 59 and the small roller 59a, the fixed plate 55 can more stably drive the second connecting shaft 53 to move up and down. At the same time, the fixed plate 55 is restricted from rotating, which can improve the use effect of the second spring 54, prevent the second spring 54 from being subjected to horizontal force, and protect the second spring 54. The setting of the protective door 12 is convenient for the staff to place the culture medium 3 on the support structure 4 Alternatively, the support structure 4 is taken out of the device housing 11 as a whole. The handle 12b provided on the protective door 12 is convenient for the staff to open or close the protective door 12. The glass 12a provided on the protective door 12 allows the staff to observe the growth status of the microorganisms in the culture medium 3 without opening the protective door 12 during cultivation. The roller 15 and the ball 16 provided on the support seat 13 can reduce the friction between the support seat 13 and the support structure 4, and facilitate the rotation of the support structure 4. At the same time, the setting of the ball 16 makes it convenient to pull the support structure 4 outward as a whole after the staff cancels the restriction on the support structure 4 by adjusting the structure 5, until the support structure 4 can be removed from the support seat 13.

[0031] First, the protective door 12 is opened by the handle 12b, and then the nutrient medium is placed in the culture medium 3, and then the microorganisms are inoculated into the nutrient medium set in the culture medium 3, and the culture medium 3 is placed downward from the top of the support disk 47 in the support structure 4. When the lower surface of the culture medium 3 contacts the support disk 47, the support disk 47 pushes the first spring 45 downward to deform, and at the same time, the support disk 47 pushes the clamping arm 44 to rotate, and the upper end of the clamping arm 44 approaches the culture medium 3. When the deformation of the first spring 45 is the largest, the upper end of the clamping arm 44 drives the clamping block 46 to fix the culture medium 3 on the support structure 4. After the culture medium 3 is placed, the electric push rod 21 is started, and the electric push rod 21 pushes the stirring structure 2 downward When the electric push rod 21 is extended to the maximum length, the lower end of the stirring rod 24 enters the culture medium 3 and is close to the bottom inner wall of the culture medium 3, the first motor 22 is started, and the first motor 22 drives the mounting plate 27 to rotate. While the mounting plate 27 rotates, it drives the outer gear 25 to rotate through the connecting rod 28. At the same time, the outer gear 25 revolves closely against the inner gear 26. As the outer gear 25 revolves, the upper end of the connecting rod 28 slides in the mounting plate 27 and squeezes the limit spring 27a to deform, so as to ensure that the outer gear 25 is always meshed with the inner gear 26 during the revolving. When the outer gear 25 rotates, it drives the stirring rod 24 to stir the microorganisms and the nutrient medium in the culture medium 3, so that the microorganisms and the nutrient medium are fully filled. The second motor 52 is started, and the second motor 52 drives the first connecting shaft 42 to rotate through the second connecting shaft 53. The first connecting shaft 42 drives the supporting structure 4 to rotate as a whole, and adjusts the positions of different fixing seats 43. After the stirring structure 2 mixes the microorganisms and nutrient medium in the culture medium 3 on different fixing seats 43, the electric push rod 21 contracts, drives the stirring structure 2 to return to its original height, and then closes the protective door 12, and sets the temperature and humidity in the device body 1 to provide a suitable environment for the cultivation of microorganisms; after the microorganisms are cultivated, the protective door 12 is opened by the handle 12b, and then the pressing rod 51 is pressed downward, and the pressing rod 51 moves downward with the fixing plate 55, and the fixing plate 55 The second connecting shaft 53 is driven downward by the bearing 56. When the second connecting shaft 53 is completely separated from the first connecting shaft 42, the support structure 4 is pulled outward, and the support structure 4 slides outward on the support seat 13. At this time, the ball 16 rolls due to the friction of the support frame 41, reducing the friction resistance of the support structure 4 sliding outward. After the support structure 4 is completely removed, the microorganisms in the culture medium 3 can be observed and studied. After adjusting the temperature and humidity in the device body 1, the next batch of microorganism inoculation can be started. At the same time, different support structures 4 can be replaced to stir and culture the configured microorganisms again, which speeds up the efficiency of microbial cultivation and facilitates research by staff.
