Description

Technical Field

[0001] This invention relates to the field of Cordyceps militaris cultivation technology, specifically to a Cordyceps militaris cultivation device and cultivation method. Background Technology

[0002] Cordyceps militaris, also known as North Cordyceps or North Cordyceps sinensis, has seen its artificial cultivation developed due to the scarcity of natural Cordyceps sinensis, increasing market demand, and breakthroughs in fungal cultivation techniques. The artificial cultivation of Cordyceps militaris is a biotechnology application with multiple attributes, including the exploitation of medicinal value, balancing market supply and demand, and upgrading the agricultural industry. The cultivation process involves a phased approach, using containers of different volumes, and is designed based on core requirements such as growth characteristics, cultivation efficiency, cost control, and quality stability. Essentially, it involves "gradient adaptation of growth stages." The refined management for large-scale production consists of four stages of propagation (stage 1: 20ml activation test tubes; stage 2: 500ml shake flasks and Erlenmeyer flasks; stage 3: 500L seed tank; stage 4: 5000L fermentation tank). This is used to solve problems such as yield loss due to spatial mismatch, mold growth due to gas exchange, nutrient supply and cost control during the cultivation of Cordyceps militaris. Because the mycelium of Cordyceps militaris easily adheres to the inner wall of the container, it is easy to damage the mycelium when transplanting Cordyceps militaris. This not only interrupts the absorption of nutrients by Cordyceps militaris, but also easily reduces the colonization ability of Cordyceps militaris, thereby increasing the risk of contamination by other microorganisms.

[0003] The existing technology has the following problems:

[0004] 1. In the use of existing Cordyceps militaris cultivation devices, the mycelium of Cordyceps militaris easily adheres to the inner wall of the container, which can easily damage the mycelium when transplanting Cordyceps militaris. This not only interrupts the absorption of nutrients by Cordyceps militaris, but also reduces the colonization ability of Cordyceps militaris, thereby increasing the risk of contamination by other microorganisms.

[0005] 2. In the use of existing Cordyceps militaris cultivation devices, Cordyceps militaris are often stacked, which makes it easy to miss observations during daily maintenance, and the replenishment of culture medium is also quite cumbersome. Summary of the Invention

[0006] This invention provides a Cordyceps militaris cultivation device and cultivation method to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A Cordyceps militaris cultivation device includes a cultivation body. A reproductive chamber and a breeding chamber are respectively located at both ends of the inner cavity of the cultivation body. A circulating exhaust fan is fixedly connected to one side of the outer wall of the cultivation body. The input and output ends of the circulating exhaust fan penetrate and are fixedly connected to the inner wall of the breeding chamber. Several supporting top plates are vertically arranged in the inner cavities of the reproductive and breeding chambers. The supporting top plates are rotatably connected to the inner walls of the corresponding reproductive and breeding chambers via several electric screws. A breathable support plate is fixedly connected to the inner wall of the reproductive and breeding chambers below the supporting top plates, and a transplanting component is provided on the top of the breathable support plate.

[0009] A further improvement of the technical solution of the present invention is that: the transplanting component includes several placement brackets slidably connected to the top of the breathable tray, and several installation grooves are opened on the top of the placement brackets, and a cultivation base is placed on the inner wall of the installation groove. A sealing block is fixedly connected to the top of the cultivation base, and several placement grooves are opened in the middle of the cultivation base. A sealing strip is fixedly connected to the inner wall of the placement groove, and the inner wall of the sealing strip contacts the bearing tube.

[0010] A further improvement of the technical solution of the present invention is that: a plurality of placement chambers are provided at the bottom of the supporting top plate, the placement chambers are arranged one-to-one with the placement brackets, and the bottom of both sides of the inner wall of the placement chamber is fixedly connected with limit blocks. A first support plate is slidably connected between the two limit blocks in the reproductive chamber, and a second support plate is slidably connected between the two limit blocks in the breeding chamber.

[0011] A further improvement of the technical solution of the present invention is that: a plurality of first limiting grooves are provided on the first support plate, the first limiting grooves are respectively arranged in correspondence with the bearing tubes on the corresponding placement brackets, and a glass tube is inserted into the inner wall of the first limiting groove. A first protrusion is fixedly connected to the outer wall of the glass tube, and the bottom of the first protrusion contacts the top of the first support plate, while the bottom of the glass tube is inserted into the top of the corresponding bearing tube.

[0012] A further improvement of the technical solution of the present invention is that: a plurality of second limiting grooves are provided on the second support plate, the second limiting grooves correspond one-to-one with the cultivation bases on the corresponding placement brackets, and a culture bottle is inserted into the inner wall of the second limiting groove. A second protrusion is fixedly connected to the outer wall of the culture bottle, and the bottom of the second protrusion contacts the top of the second support plate, while the bottom of the culture bottle is inserted into the outer wall of the corresponding sealing block.

[0013] A further improvement of the technical solution of the present invention is that: a worm gear is rotatably connected at the center of the inner wall of the placement chamber, and a transmission block is fixedly connected at the end of the worm gear after passing through the side wall of the placement chamber. The outer wall of the transmission block is rotatably connected to the outer wall of the corresponding support top plate, and a slot is provided on one side of the outer wall of the transmission block.

[0014] A further improvement of the technical solution of the present invention is that: several hollow worm wheels are threadedly connected to both sides of the outer wall of the worm, and the top of the hollow worm wheel is rotatably connected to the top of the inner wall of the placement chamber, while an extension rod is slidably connected to the inner wall of the hollow worm wheel.

[0015] A further improvement of the technical solution of the present invention is that: the top of the inner wall of the placement chamber is provided with a threaded groove corresponding to the hollow worm gear, and a miniature lead screw is threadedly connected to the inner wall of the threaded groove. The bottom of the miniature lead screw is fixedly connected to the top of the extension rod. A push plate is also provided in the middle of the inner cavity of the placement chamber, and the bottom of the extension rod is fixedly connected to the corresponding push plate.

[0016] A further improvement of the technical solution of the present invention is that: the outer wall of the extension rod is provided with sliding grooves on both sides, and the inner wall of the sliding groove is slidably connected with a slider, and the two ends of the slider are fixedly connected to the inner wall of the hollow worm gear.

[0017] A method for cultivating Cordyceps militaris, using the aforementioned Cordyceps militaris cultivation device, is as follows:

[0018] S1: By setting a reproductive chamber and a propagation chamber at both ends of the inner cavity of the cultivation body, and setting several breathable trays on the inner walls of the reproductive chamber and the propagation chamber, the inoculated bacteria are placed into the carrier tube, and the carrier tube together with the cultivation base is installed on the top of the placement bracket. Then the placement bracket is placed on the breathable tray in the reproductive chamber, and then several glass tubes are installed in the first support plate. The first support plate is sent into the placement chamber in the reproductive chamber, and the push plate in the reproductive chamber is controlled to limit the top of the glass tube. Finally, the electric screw in the reproductive chamber is activated to drive the glass tube to move down as a whole and install it with the corresponding carrier tube.

[0019] S2: By starting the electric screw, the support top plate and the first support plate are moved upward as a whole, and the bearing tube is separated from the corresponding glass tube. Then, the placement bracket is pulled out and sent into the ventilated tray in the propagation chamber. Then, the inoculum bottle is installed in the second support plate and the second support plate is sent into the placement chamber in the propagation chamber. The push plate in the propagation chamber is controlled to fix the top of the inoculum bottle, and the electric screw in the propagation chamber is started to assemble the bottom of the inoculum bottle with the top of the corresponding cultivation base.

[0020] S3: The rocker arm drives the transmission block at the end of the worm to rotate, and the rotating worm drives the hollow worm wheel on the outer wall to rotate synchronously. The slider on the inner wall drives the miniature lead screw on the top of the extension rod to rotate in the threaded groove, thereby controlling the push plate at the bottom of the extension rod to move up and down.

[0021] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0022] 1. This invention provides a Cordyceps militaris cultivation device and method. A sealing block is installed at the top of the cultivation base, causing the inner wall of the descending spawn bottle to press against the sealing block, deforming it and sealing the gap between the spawn bottle and the cultivation base. Then, the handle is used to pull out the placement support, and the culture solution is poured from the top of the spawn bottle onto the surface of the cultivation base, ensuring the culture solution covers the carrier tube but does not exceed the sealing block. A cork is then installed at the opening of the spawn bottle, and the handle is used to push the placement support back into the propagation chamber. The push plate inside the propagation chamber is adjusted so that the bottom of the push plate contacts the top of the cork. This further solves the problem that in traditional Cordyceps militaris cultivation devices, the mycelium of Cordyceps militaris easily adheres to the inner wall of the container, causing damage to the mycelium during transplantation. This not only interrupts nutrient absorption but also reduces the colonization ability of Cordyceps militaris, thus increasing the risk of contamination by other microorganisms.

[0023] 2. This invention provides a Cordyceps militaris cultivation device and method. Several hollow worm gears are installed at the top of the inner wall of the placement chamber, with the outer walls of the hollow worm gears all fitting against a worm shaft. The worm shaft drives the hollow worm gears to rotate synchronously. A threaded groove is provided at the top of the inner wall of the placement chamber, and a miniature lead screw is installed on the inner wall of the threaded groove. An extension rod is installed at the bottom of the miniature lead screw. Sliding grooves are provided on both sides of the outer wall of the extension rod, and sliding blocks on the inner walls of the sliding grooves are connected to the inner walls of the hollow worm gears. When the hollow worm gears rotate, the sliding blocks push the extension rod to rotate, causing the miniature lead screw at its top to rotate upwards continuously within the threaded groove. This causes the extension rod to move the push plate at its bottom upwards, thus freeing the bottom of the push plate from the restriction of the cork at the top of the glass tube or the spawn bottle. This further solves the problem that in traditional Cordyceps militaris cultivation devices, the stacking of Cordyceps militaris often leads to missed observations and cumbersome replenishment of the culture medium during daily maintenance.

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 12As shown in the figure, an embodiment of the present invention provides a Cordyceps militaris cultivation device, including a cultivation body 1. A reproductive chamber 2 and a breeding chamber 3 are respectively arranged at both ends of the inner cavity of the cultivation body 1. A circulating exhaust fan 4 is fixedly connected to one side of the outer wall of the cultivation body 1. The input and output ends of the circulating exhaust fan 4 penetrate and are fixedly connected to the inner wall of the breeding chamber 3. Several supporting top plates 6 are arranged vertically in the inner cavities of the reproductive chambers 2 and 3. The supporting top plates 6 are rotatably connected to the inner walls of the corresponding reproductive chambers 2 and 3 via several electric screws 5. The inner walls of the reproductive chambers 2 and 3 are supported by the supporting top plates 6. A breathable support plate 7 is fixedly connected to each of the lower positions, and a transplanting assembly is provided on the top of the breathable support plate 7. The transplanting assembly includes several placement brackets 8 slidably connected to the top of the breathable support plate 7, and several mounting grooves 9 are opened on the top of the placement brackets 8. A cultivation base 10 is placed on the inner wall of the mounting groove 9. A sealing block 11 is fixedly connected to the top of the cultivation base 10, and several placement grooves 12 are opened in the middle of the cultivation base 10. A sealing strip 13 is fixedly connected to the inner wall of the placement groove 12, and the inner wall of the sealing strip 13 contacts the bearing tube 14. Several placement chambers 15 are opened at the bottom of the supporting top plate 6. The placement chamber 15 and the placement bracket 8 are respectively arranged in a one-to-one correspondence. Limiting blocks 16 are fixedly connected to the bottom of both sides of the inner wall of the placement chamber 15. A first support plate 17 is slidably connected between the two limiting blocks 16 in the reproductive chamber 2, and a second support plate 18 is slidably connected between the two limiting blocks 16 in the breeding chamber 3. The first support plate 17 has several first limiting grooves 19, each corresponding to a carrying tube 14 on the placement bracket 8. A glass tube 20 is inserted into the inner wall of the first limiting groove 19, and a fixed connection is made to the outer wall of the glass tube 20. A first protrusion 21 is provided, and the bottom of the first protrusion 21 contacts the top of the first support plate 17. The bottom of the glass tube 20 is inserted into the top of the corresponding carrier tube 14. A plurality of second limiting grooves 22 are provided on the second support plate 18. The second limiting grooves 22 correspond one-to-one with the cultivation base 10 on the corresponding placement bracket 8. A culture bottle 23 is inserted into the inner wall of the second limiting groove 22. A second protrusion 24 is fixedly connected to the outer wall of the culture bottle 23. The bottom of the second protrusion 24 contacts the top of the second support plate 18. The bottom of the culture bottle 23 is inserted into the outer wall of the corresponding sealing block 11.

[0039] During operation, reproductive chambers 2 and spawn chambers 3 are respectively set at both ends of the inner cavity of the cultivation body 1, and several breathable trays 7 are set on the inner walls of the reproductive chambers 2 and spawn chambers 3. When the first stage of cultivation of Cordyceps militaris is carried out, several placement grooves 12 are set in the inner cavity of the cultivation base 10, and sealing strips 13 are set on the inner walls of the placement grooves 12. At this time, the carrier tubes 14 are installed in the placement grooves 12 in sequence, and the outer wall of the carrier tubes 14 is in contact with the surface of the sealing strips 13. Then, wheat culture medium and inoculum are placed into the carrier tubes 14 in sequence, and the cultivation base 10 containing the inoculum is installed in the installation groove 9 set on the top of the placement bracket 8. Hold the handle on one side of the outer wall of the placement bracket 8 and lift one end of the bottom of the placement bracket 8 to move the placement bracket 8 to the surface of the ventilated tray 7. Then, use the handle to push the placement bracket 8 into the cultivation body 1. Since the inner walls of the reproductive chamber 2 and the breeding chamber 3 are provided with several electric lead screws 5 (here, the electric lead screw 5 is composed of a motor and a lead screw, which is the prior art), and the outer walls of the electric lead screws 5 are provided with several support top plates 6, the placement chamber 15 is set at the bottom of the support top plate 6, and the limiting blocks 16 are set at the bottom of both sides of the inner wall of the placement chamber 15. At this time, several first limiting grooves 19 are set on the top of the first support plate 17, and Several glass tubes 20 (here, glass tubes 20 are custom-made test tubes with the bottoms cut off, belonging to existing technology) are sequentially inserted into the first limiting groove 19. Since one end of the outer wall of the glass tube 20 is provided with a first protrusion 21, the first protrusion 21 is used to support the glass tube 20. Then, the assembled first support plate 17 is sent into the placement chamber 15 along the inner wall of the limiting block 16, and the push plate 32 provided on the inner wall of the placement chamber 15 is controlled to move down so that its bottom contacts the top of the glass tube 20, thereby limiting the glass tube 20. At this time, the electric screw 5 is activated, which drives the support top plate 6, the first support plate 17 and the push plate 32. Simultaneously move downwards and insert the bottom of the glass tube 20 into the top of the support tube 14. Then control the push plate 32 to move upwards, releasing the glass tube 20 from its restriction. At the same time, use the handle to remove the placement bracket 8 and the first support plate 17 from the reproductive chamber 2. At this time, inject the culture medium into the support tube 14 along the end of the glass tube 20, so that the culture medium is two-thirds full in the support tube 14 and completely submerges the bacteria. Then install the cork on the top of the glass tube 20 in sequence, and use the handle to push the placement bracket 8 and the first support plate 17 into the reproductive chamber 2 again. Then control the push plate 32 to move downwards again and make it contact the cork on the top of the glass tube 20.

[0040] It should be further explained that the environmental requirements for the first and second stages of Cordyceps militaris growth differ significantly. In the first stage, Cordyceps militaris requires a dark environment with a temperature controlled between 20 and 22 degrees Celsius and an air humidity of 60% to 65%, with ventilation for 30 to 40 minutes 1-2 times daily. In the second stage, however, it requires 10 to 12 hours of diffused light daily, a temperature reduced to 18 to 20 degrees Celsius, and an air humidity increased to 80% to 90%. Meanwhile, ventilation is required 3 to 5 times a day for 30 to 50 minutes each time. When the Cordyceps militaris grows to the second stage (the temperature control device, diffused light irradiation device, and humidity adjustment device required for Cordyceps militaris cultivation are all existing technologies), the electric screw 5 installed on the inner wall of the reproductive chamber 2 is activated, which drives the top support plate 6, push plate 32, first support plate 17, and glass tube 20 to detach from the carrier tube 14. At this time, the height of the Cordyceps militaris plant in the carrier tube 14 is about 2 to 3 cm, and the mycelial thickness in the carrier tube 14 is about 0.3 to 0.5 cm, not exceeding the support tube 14, at this time, use the handle to pull out the placement bracket 8 placed on top of the ventilated tray 7 in sequence, and transfer the placement bracket 8 to the propagation chamber 3 set at one end of the inner cavity of the cultivation body 1. Since the propagation chamber 2 and propagation chamber 3 have the same structure as the electric screw 5, support top plate 6, ventilated tray 7, etc., the placement bracket 8 is then installed on the surface of the ventilated tray 7 in the propagation chamber 3. Since the top of the second support plate 18 is provided with several second limiting grooves 22, the corresponding number of inoculum bottles 23 (here, the inoculum bottles 23 are custom bottles with cut bottoms, which belongs to the prior art) are placed. The culture bottle 23 is placed in the second limiting groove 22. Since a second protrusion 24 is provided at one end of the outer wall of the culture bottle 23, the second protrusion 24 supports the culture bottle 23 within the second limiting groove 22. After the culture bottle 23 is installed, the second support plate 18 is sent into the placement chamber 15 within the propagation chamber 3, and the second support plate 18 is supported by limiting blocks 16 provided at the bottom of both sides of its inner wall. Then, the push plate 32 is controlled to limit the top of the culture bottle 23, and the electric screw 5 within the propagation chamber 3 is activated, causing the top support plate 6 to drive the push plate 32 and the second support plate 18 downwards, thus moving the culture bottle 23... The bottom of the 3-cell culture bottle 23 fits against the top of the culture base 10. Since the top of the culture base 10 has a sealing block 11, the inner wall of the lowered culture bottle 23 applies pressure to the sealing block 11, causing it to deform and sealing the gap between the culture bottle 23 and the culture base 10. Then, the handle is used to pull out the placement bracket 8, and the culture medium is poured down the top of the culture bottle 23 onto the surface of the culture base 10, ensuring the culture medium covers the carrier tube 14 but does not exceed the sealing block 11. The cork is then installed at the opening of the culture bottle 23, and the handle is used to push the placement bracket 8 back into the culture chamber 3. The contents of the culture chamber 3 are then adjusted. The push plate 32 is used to bring its bottom into contact with the top of the wooden plug. Finally, the circulating exhaust fan 4 (composed of a circulating fan, exhaust port, and air inlet, which is existing technology) installed on one side of the outer wall of the cultivation body 1 is turned on to replace the air in the propagation chamber 3. This further solves the problem that in traditional Cordyceps militaris cultivation devices, the mycelium of Cordyceps militaris easily adheres to the inner wall of the container, which can easily damage the mycelium during transplantation. This not only interrupts the absorption of nutrients by Cordyceps militaris but also reduces its colonization ability, thereby increasing the risk of contamination by other microorganisms.

[0041] It should be further explained that after the second stage of Cordyceps militaris growth is completed, the cultivation body 1 is opened and the electric screw 5 installed on the inner wall of the propagation chamber 3 is activated, so that the spawn bottle 23 is detached from the sealing block 11 installed on the top of the cultivation base 10. At this time, the placement bracket 8 is pulled out using the handle, and the cultivation base 10 is pushed from the bottom to detach it from the installation groove 9 installed on the top of the placement bracket 8. At this time, the Cordyceps militaris in the second stage are more concentrated in space, making the mycelium more firmly attached. By placing the cultivation base 10 with the support tube 14 installed on the table and applying slight force to the two ends of the top of the cultivation base 10, the support tube 14 is detached from the placement groove 12, and the mycelium wrapped around the top of the cultivation base 10 is lifted in a funnel shape. Then, the cultivation base 10 is rotated slightly to detach the Cordyceps militaris attached to its top. Finally, the root of the Cordyceps militaris is held and the support tube 14 is pinched and slowly twisted to detach the mycelium of the Cordyceps militaris from the support tube 14, making it easier to transplant it into the turnover box for the third stage of growth.

[0042] It should be reiterated that the traditional Cordyceps militaris cultivation process typically involves a four-stage transplantation process: a 20ml activation test tube, a 500ml Erlenmeyer flask, a 500L seed tank, and a 5000L fermentation tank. To prevent residual mycelium and culture medium from deteriorating and affecting subsequent Cordyceps militaris cultivation, the used containers are usually disinfected and cleaned. However, when dealing with the 20ml activation test tube and the 500ml Erlenmeyer flask, due to their small size and special structure, manual cleaning with tools is often required. In this invention, the carrier tube 14, cultivation base 10, glass tube 20, and spawn bottle 23 are designed for disassembly and assembly. This not only avoids dead corners inside the container, preventing tedious cleaning, but also allows for large-scale batch cleaning by disassembling the carrier tube 14, cultivation base 10, glass tube 20, and spawn bottle 23. This effectively avoids dead corners inside the container and significantly improves the cleaning efficiency of the cultivation container.

[0043] A worm gear 25 is rotatably connected to the center of the inner wall of the placement chamber 15. The end of the worm gear 25 passes through the side wall of the placement chamber 15 and is fixedly connected to a transmission block 26. The outer wall of the transmission block 26 is rotatably connected to the outer wall of the corresponding support top plate 6, and a slot 27 is provided on one side of the outer wall of the transmission block 26. Several hollow worm wheels 28 are threadedly connected to both sides of the outer wall of the worm gear 25, and the top of the hollow worm wheels 28 is rotatably connected to the top of the inner wall of the placement chamber 15. An extension rod 29 is slidably connected to the inner wall of the hollow worm wheels 28. The top of the wall is provided with threaded grooves 30 corresponding to the hollow worm gears 28, and the inner wall of the threaded grooves 30 is threaded with miniature lead screws 31. The bottom of the miniature lead screws 31 is fixedly connected to the top of the extension rods 29. The inner cavity of the placement chamber 15 is also provided with a push plate 32. The bottom of each extension rod 29 is fixedly connected to the corresponding push plate 32. The outer walls of the extension rods 29 are provided with sliding grooves 33 on both sides, and the inner walls of the sliding grooves 33 are slidably connected with sliders 34. The two ends of the sliders 34 are fixedly connected to the inner walls of the hollow worm gears 28.

[0044] During operation, a worm gear 25 is installed at the center of the inner wall of the placement chamber 15, and a transmission block 26 is installed at the end of the worm gear 25. Since a slot 27 is provided on one side of the outer wall of the transmission block 26, when it is necessary to replenish the Cordyceps militaris with culture medium, the corresponding rocker arm (here the rocker arm is a curved metal rod with a square end, corresponding to the size of the slot 27) is inserted into the slot 27, and the rocker arm is rotated to make the transmission block 26 drive the worm gear 25 to rotate. Since several hollow worm wheels 28 are provided at the top of the inner wall of the placement chamber 15, and the outer walls of the hollow worm wheels 28 are all The worm gear 25 is engaged with the hollow worm wheel 28, thereby driving the hollow worm wheel 28 to rotate synchronously. The top of the inner wall of the storage chamber 15 is provided with threaded grooves 30 corresponding to the number of hollow worm wheels 28, and the inner wall of each threaded groove 30 is provided with a miniature lead screw 31. The bottom of each miniature lead screw 31 is provided with an extension rod 29. Both sides of the outer wall of the extension rod 29 are provided with sliding grooves 33, and the sliders 34 on the inner wall of the sliding grooves 33 are connected to the inner wall of the hollow worm wheel 28. Therefore, when the hollow worm wheel 28 rotates, the sliders 34 push the extension rod 29 to rotate. The extension rod 29 drives the micro-lead rod 31 at its top to rotate upwards continuously within the threaded groove 30 (at this time, the micro-lead rod 31 in the symmetrical direction is opposite to the thread direction of the threaded groove 30, so that when the stacked micro-lead rods 31 rotate, they can move synchronously within the threaded groove 30). The extension rod 29 also drives the push plate 32 at its bottom to move upwards, thus freeing the bottom of the push plate 32 from the restriction of the cork at the top of the glass tube 20 or the culture bottle 23. At this point, the handle is used to pull out the placement bracket 8, and the glass tubes on the entire row of placement brackets 8... Observe the Cordyceps militaris in the glass tube 20 or the inoculum bottle 23, and remove the cork as needed. Add culture medium to the glass tube 20 or the inoculum bottle 23. After the culture medium is replenished, put the cork back into the top of the glass tube 20 or the inoculum bottle 23. Then push the placement bracket 8 back into the cultivation body 1 and rotate the rocker again so that the push plate 32 restricts the cork. This further solves the problem that in the traditional Cordyceps militaris cultivation device, Cordyceps militaris is often stacked and stored, which makes it easy to miss observations and makes replenishing the culture medium cumbersome during daily maintenance.

[0045] A method for cultivating Cordyceps militaris, using the aforementioned Cordyceps militaris cultivation device, is as follows:

[0046] S1: By setting a reproductive chamber 2 and a breeding chamber 3 at both ends of the inner cavity of the cultivation body 1, and setting several breathable trays 7 on the inner walls of the reproductive chamber 2 and the breeding chamber 3, the inoculated bacteria are placed into the carrier tube 14, and the carrier tube 14 together with the cultivation base 10 is installed on the top of the placement bracket 8. Then the placement bracket 8 is placed on the breathable tray 7 in the reproductive chamber 2. Then several glass tubes 20 are installed in the first support plate 17. The first support plate 17 is sent into the placement chamber 15 in the reproductive chamber 2. The push plate 32 in the reproductive chamber 2 is controlled to limit the top of the glass tube 20. Finally, the electric screw 5 in the reproductive chamber 2 is started to drive the glass tube 20 to move down as a whole and install it with the corresponding carrier tube 14.

[0047] S2: By starting the electric screw 5, the supporting top plate 6 and the first supporting plate 17 are moved upward as a whole, and the carrying tube 14 is separated from the corresponding glass tube 20. Then, the placement bracket 8 is pulled out and sent into the ventilated tray 7 in the propagation chamber 3. Then, the spawn bottle 23 is installed in the second supporting plate 18 and the second supporting plate 18 is sent into the placement chamber 15 in the propagation chamber 3. The push plate 32 in the propagation chamber 3 is controlled to fix the top of the spawn bottle 23, and the electric screw 5 in the propagation chamber 3 is started to assemble the bottom of the spawn bottle 23 with the top of the corresponding cultivation base 10.

[0048] S3: The rocker arm drives the transmission block 26 at the end of the worm 25 to rotate, and the rotating worm 25 drives the hollow worm wheel 28 on the outer wall to rotate synchronously. The slider 34 on the inner wall drives the miniature lead screw 31 on the top of the extension rod 29 to rotate in the threaded groove 30 through the slide groove 33, thereby controlling the push plate 32 at the bottom of the extension rod 29 to move up and down.

[0049] The working principle of the Cordyceps militaris cultivation device and cultivation method will be explained in detail below.

[0050] like Figures 1 to 12As shown, by setting a reproductive chamber 2 and a breeding chamber 3 at both ends of the inner cavity of the cultivation body 1, and setting several breathable trays 7 on the inner walls of the reproductive chamber 2 and the breeding chamber 3, when the first stage of cultivation of Cordyceps militaris is carried out, by setting several placement grooves 12 in the inner cavity of the cultivation base 10, and setting sealing strips 13 on the inner wall of the placement grooves 12, the carrying tubes 14 are installed in the placement grooves 12 in sequence, and the outer wall of the carrying tubes 14 is in contact with the surface of the sealing strips 13. Then, the wheat culture medium and the inoculum are placed into the carrying tubes 14 in sequence, and the cultivation base 10 containing the inoculum is installed in the installation groove 9 set at the top of the placement bracket 8. Then, the outer wall of the placement bracket 8 is held... A handle is provided on the side, and one end of the placement bracket 8 is lifted to move the placement bracket 8 to the surface of the ventilated support plate 7. The placement bracket 8 is then pushed in using the handle. Since the inner walls of the reproductive chamber 2 and the breeding chamber 3 are provided with several electric screws 5, and the outer walls of the electric screws 5 are provided with several support top plates 6, a placement chamber 15 is provided at the bottom of the support top plate 6, and limiting blocks 16 are provided at the bottom of both sides of the inner wall of the placement chamber 15. At this time, several first limiting grooves 19 are provided on the top of the first support plate 17, and several glass tubes 20 are inserted into the first limiting grooves 19 in sequence. Since one end of the outer wall of the glass tube 20 is provided with a first protrusion 21, the first protrusion 21 is used to... The glass tube 20 is supported, and then the assembled first support plate 17 is fed into the placement chamber 15 along the inner wall of the limiting block 16. The push plate 32 on the inner wall of the placement chamber 15 is controlled to move downward so that its bottom contacts the top of the glass tube 20, thereby limiting the glass tube 20. At this time, the electric screw 5 is activated, which drives the top support plate 6, the first support plate 17 and the push plate 32 to move downward synchronously, so that the bottom of the glass tube 20 is inserted into the top of the carrier tube 14. Then, the push plate 32 is controlled to move upward, releasing the glass tube 20. At the same time, the handle, along with the placement bracket 8 and the first support plate 17, is used to detach the reproductive chamber 2. At this time, the culture medium is sequentially flowed down the glass tube 2. The end of the culture medium is injected into the carrier tube 14, so that the culture medium is two-thirds full in the carrier tube 14 and completely submerges the inoculum. Then, the cork is installed on the top of the glass tube 20 in sequence, and the placement bracket 8 and the first support plate 17 are pushed into the reproductive chamber 2 again using the handle. The push plate 32 is then moved down again and made to contact the cork installed on the top of the glass tube 20. This further solves the problem that in the traditional Cordyceps militaris cultivation device, the mycelium of Cordyceps militaris is easy to adhere to the inner wall of the container, which can easily damage the mycelium when transplanting Cordyceps militaris. This not only interrupts the absorption of nutrients by Cordyceps militaris, but also easily reduces the colonization ability of Cordyceps militaris, thereby increasing the risk of contamination by other microorganisms.

[0051] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
