[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] This utility model provides an inoculation device for edible fungi spawn. The specific implementation method is described in detail with reference to Figures 1 to 5. The overall structure of the device is shown in Figure 1, including a base 1, a support frame 2, an inoculation component 5, a rotating component, a stirring component, and a cleaning component. These components work together to achieve efficient, automated, and highly applicable edible fungi spawn inoculation operation.

[0025] The base 1 serves as the basic support for the entire device. A support frame 2 is fixedly connected to one side of the base 1. The support frame 2 is used to install and fix the inoculation component 5. A door 3 is hinged to the inside of the base 1. A handle 4 is fixedly connected to the front of the door 3. The design of the door 3 provides operators with a convenient maintenance and cleaning passage. The door 3 can be easily opened through the handle 4 to clean or inspect the inside of the device. A shaft hole is opened inside the base 1 for installing the rotating shaft 12. The rotating shaft 12 is connected to the stepper motor 13 through a coupling, thereby realizing the rotation function of the rotating disk 11.

[0026] The inoculation assembly 5 is one of the core components of this invention. As shown in Figure 2, it includes a bacterial culture tank 6, an infusion pump 7, an infusion tube 8, and an inoculation tube 9. The bacterial culture tank 6 is fixed to the top of the support frame 2 and is used to store bacterial culture. A liquid addition tube 22 is embedded in the top of the bacterial culture tank 6. A sealing plug 23 is threaded onto the inner side of the liquid addition tube 22. A pull block is fixedly connected to the top of the sealing plug 23. In actual use, the operator can unscrew the sealing plug 23 to add bacterial culture into the bacterial culture tank 6 through the liquid addition tube 22, and then tighten the sealing plug 23 to ensure the airtightness of the bacterial culture tank 6 and prevent leakage or contamination of the bacterial culture. The infusion pump 7 is fixed to the outer wall of the bacterial culture tank 6 and communicates with the inside of the bacterial culture tank 6. It is used to draw the bacterial culture from the bacterial culture tank 6 and deliver it to the inoculation tube 9 through the infusion tube 8. The infusion tube 8 extends into the interior of the support frame 2 and communicates with the inoculation tube 9. A valve 10 is provided at the bottom of the inoculation tube 9. By adjusting the opening of the valve 10, the flow rate of the bacterial solution can be precisely controlled, thereby achieving uniform dripping of the bacterial solution. A rotating disk 11 is provided below the inoculation tube 9. The rotating disk 11 is used to carry multiple culture media 16 and is automatically positioned by being driven by a stepper motor 13.

[0027] The rotating component, as shown in Figure 4, includes a rotating disk 11, a rotating shaft 12, and a stepper motor 13. A limiting groove 14 is provided on the top of the rotating disk 11. The limiting groove 14 is tapered, with a larger opening at the top and a smaller opening at the bottom. Multiple elastic rubber balls 15 are fixedly connected inside the groove.

[0028] In actual operation, the operator can fill multiple culture media 16 into the limiting grooves 14 on the rotating disk 11. The conical design of the limiting grooves 14, combined with the elasticity of the elastic rubber balls 15, allows the device to adapt to and fix culture media 16 of different sizes, preventing the culture media 16 from shifting position during rotation. A rotating shaft 12 is fixedly connected to the bottom of the rotating disk 11, and the rotating shaft 12 is connected to a stepper motor 13 via a coupling. The stepper motor 13 is fixedly installed inside the base 1. After the stepper motor 13 is started, it drives the rotating disk 11 to rotate through the rotating shaft 12, causing the culture media 16 to move sequentially to directly below the inoculation tube 9, achieving automatic positioning. The precise control capability of the stepper motor 13 ensures that the rotation angle of the rotating disk 11 is accurate, thereby improving inoculation efficiency.

[0029] The specific structure of the stirring and cleaning components is shown in Figures 2 and 3, including a servo motor 17, a stirring shaft 18, a stirring rod 19, a flexible scraper 20, and a drain pipe 21. The servo motor 17 is fixedly installed on the top of the bacterial culture tank 6. The output end of the servo motor 17 is connected to the stirring shaft 18 through a coupling. The stirring rod 19 is fixedly connected to the outer wall of the stirring shaft 18. One end of the stirring rod 19 is fixedly connected to the flexible scraper 20, and the outer wall of the flexible scraper 20 is in contact with the inner wall of the bacterial culture tank 6.

[0030] In actual use, after the servo motor 17 is started, it drives the stirring rod 19 to rotate through the stirring shaft 18. During the rotation of the stirring rod 19, the bacterial solution is stirred to avoid bacterial sedimentation and aggregation due to gravity or temperature changes, ensuring uniform distribution of the bacterial solution. At the same time, the flexible scraper 20 rotates with the stirring rod 19 to scrape off the bacterial solution remaining on the inner wall of the bacterial solution tank 6, reducing bacterial solution waste and facilitating subsequent cleaning. The bottom inner side of the bacterial solution tank 6 is connected to a drain pipe 21 for draining the wastewater after cleaning. The flexible scraper 20 is made of flexible material, which can effectively scrape off the residue on the inner wall of the bacterial solution tank 6 without damaging the inner wall of the bacterial solution tank 6, thus extending the service life of the bacterial solution tank 6.

[0031] The inoculation device of this invention achieves automated inoculation through the following steps: Multiple culture media 16 are loaded into the limiting grooves 14 on the rotating disk 11, and the elastic rubber balls 15 are used to fix the culture media 16 of different sizes; the stepper motor 13 is started, driving the rotating disk 11 to rotate via the rotating shaft 12, causing the culture media 16 to move sequentially to directly below the inoculation tube 9; the infusion pump 7 is started, delivering the bacterial solution in the bacterial solution tank 6 to the inoculation tube 9 through the infusion tube 8, and controlling the flow rate of the bacterial solution through the valve 10 to achieve uniform dripping of the bacterial solution; during the inoculation process, the servo motor 17 is started, stirring the bacterial solution through the stirring rod 19, while the flexible scraper 20 cleans the residual bacterial solution on the inner wall of the bacterial solution tank 6. The coordinated operation of the above steps significantly improves inoculation efficiency and accuracy, reduces manual intervention, and lowers the workload of operators.

[0032] In practical applications, this device is suitable for inoculating various edible fungi strains. For example, in the inoculation of morel mushrooms, the operator first places multiple containers filled with culture medium 16 into the limiting groove 14 of the rotating disk 11, and fixes the position of the culture medium 16 by the elastic action of the elastic rubber ball 15. Then, the operator starts the stepper motor 13, and the rotating disk 11 starts to rotate, moving the first culture medium 16 directly below the inoculation tube 9. At this time, the operator starts the infusion pump 7, which delivers the bacterial solution in the bacterial solution tank 6 to the inoculation tube 9 through the infusion tube 8, and precisely controls the flow rate of the bacterial solution through the valve 10, so that the bacterial solution drips evenly onto the surface of the culture medium 16. After the inoculation of the first culture medium 16 is completed, the stepper motor 13 drives the rotating disk 11 to rotate again, moving the next culture medium 16 directly below the inoculation tube 9, and repeats the above inoculation process. Throughout the inoculation process, the servo motor 17 runs continuously, stirring the bacterial solution with the stirring rod 19, while the flexible scraper 20 cleans the residual bacterial solution on the inner wall of the bacterial solution tank 6, ensuring the uniformity of the bacterial solution and the cleanliness of the bacterial solution tank 6.

[0033] This invention provides an efficient, convenient, and highly adaptable edible fungi inoculation device through automated design, multifunctional component integration, and user-friendly structural optimization. Firstly, the coordinated operation of the infusion pump 7, infusion tube 8, and inoculation tube 9, combined with the precise flow control function of the valve 10, reduces manual intervention and significantly improves inoculation efficiency and accuracy. Secondly, the rotating disc 11 can simultaneously hold multiple culture media 16 and achieves automatic positioning via a stepper motor 13, greatly enhancing production efficiency. Thirdly, the conical design of the limiting groove 14, combined with the elastic fixing function of the elastic rubber ball 15, allows the device to adapt to culture media 16 of different sizes, enhancing its applicability and flexibility. Furthermore, the design of the liquid addition tube 22 and sealing plug 23 facilitates the addition and sealing of the bacterial solution, while the combined use of the stirring rod 19 and flexible scraper 20 ensures uniform distribution of the bacterial solution and effectively cleans residual bacterial solution from the inner wall of the bacterial solution tank 6, avoiding waste. Finally, the design of the door 3 and handle 4 facilitates maintenance and cleaning by operators, improving the maintainability of the equipment.

[0034] In summary, this utility model, through the coordinated work and optimized design of its components, achieves efficient and precise inoculation of edible fungi strains, and has significant practical value and promotional significance.
