Description

Technical Field

[0001] This invention relates to the field of golden ear fungus cultivation technology, and in particular to an automated mycelium injection device for golden ear fungus cultivation. Background Technology

[0002] Golden ear fungus is a type of fungus that can be used in food and medicine. In its cultivation, the mycelium is typically prepared into a mycelial solution, which is then injected into the substrate bag. This injection process involves pressing a small indentation (usually the size of a corn kernel) into the substrate bag, lifting the plastic film at the indentation, and finally using a syringe or similar device to pierce the film and inject the mycelial solution into the indentation. In contrast, the cultivation of other fungi like wood ear fungus only requires injecting the mycelial solution into the substrate bag. Therefore, the mycelial injection process for golden ear fungus is more complex than that for wood ear fungus.

[0003] In existing technologies, injecting mycelium into wood ear mushrooms only requires the use of syringes or similar equipment to directly pierce the inside of the mycelium bag and then inject. However, the mycelium injection process for auricularia auricula-judae requires more attention to detail. For example, the size of the small pit formed by squeezing the mycelium bag and the separation of the culture medium and plastic film in the small pit of the mycelium bag all require extra care. In the process of injecting mycelium auricula-judae, most of the time only some liquid delivery equipment can be used to supply the mycelium solution. The specific injection operation still requires the operation of workers with certain experience. Therefore, there is an urgent need for an automated mycelium injection device suitable for auricularia auricula-judae. Summary of the Invention

Detailed Implementation

[0071] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0072] The following is combined with Figures 1 to 9 As shown, this embodiment of the invention provides an automated mycelium injection device for auricularia auricula cultivation, comprising:

[0073] Base 101, on which a storage component is provided, the storage component is used to store liquid auricularia auricula-judae spawn;

[0074] Liquid supply assembly, which is fixed on base 101;

[0075] The liquid supply assembly includes:

[0076] Cylinder 401, which is fixed to base 101;

[0077] The first piston 407 is slidably disposed inside the cylinder 401, and a hollow shaft 405 is provided on one side of the first piston 407.

[0078] An adjustment assembly is located inside the cylinder block 401 and is used to adjust the stroke of the hollow shaft 405.

[0079] The second piston 903 is slidably disposed inside the hollow shaft 405, and a transmission rod 901 is provided on one side of the second piston 903;

[0080] Damping block 902 is fixedly sleeved on transmission rod 901, and damping block 902 abuts against the inner wall of hollow shaft 405;

[0081] A gas storage component is mounted on the base 101 and is connected to the hollow shaft 405.

[0082] A mounting frame 601 is fixed on a base 101. Multiple inoculation components are provided on the mounting frame 601. All inoculation components are connected to a gas storage component. The gas storage component is used to drive the inoculation components to work.

[0083] The power component is mounted on the base 101 and is connected to the storage component and the transmission rod 901 for transmission.

[0084] Depending on the number of inoculum bags, the stroke of the hollow shaft 405 is controlled by the adjustment component, thereby controlling the stroke of the first piston 407 to achieve control of the amount of inoculum injected in a single operation. When the hollow shaft 405 is restricted by the adjustment component during its movement, the power component enables the transmission rod 901 to overcome the friction between the damping block 902 and the hollow shaft 405, thereby driving the second piston 903 to move.

[0085] The second piston 903 moves to inject gas into the gas storage component. Through the reciprocating movement of the second piston 903, a high-pressure gas environment and a low-pressure gas environment are created by the gas storage component. The high-pressure gas and the low-pressure gas are used to drive the placement and injection component to work.

[0086] Furthermore, the adjustment components include:

[0087] The threaded cylinder 802 has a first thread on its outer side wall and a second thread on its inner side wall end of the cylinder body 401. The first thread and the second thread are compatible, and the threaded cylinder 802 is disposed at the end of the cylinder body 401 through the first thread and the second thread.

[0088] Transmission block 801 is fixed at the end of threaded cylinder 802. The side wall of threaded cylinder 802 has a through hole, and hollow shaft 405 passes through threaded cylinder 802 and through hole.

[0089] The first limiting ring 804 is disposed inside the cylinder body 401. A plurality of connecting rods 803 are provided on one side of the first limiting ring 804, and the plurality of connecting rods 803 are all fixed to the end of the threaded cylinder 802.

[0090] The second limiting ring 805 is fixed on the inner wall of the cylinder 401, and the first piston 407 is located between the second limiting ring 805 and the first limiting ring 804.

[0091] The operator drives the transmission block 801 to rotate using a tool. When the transmission block 801 rotates, it drives the threaded cylinder 802 to rotate. In conjunction with the first thread and the second thread, the threaded cylinder 802 moves within the cylinder 401. Then, the position of the first limiting ring 804 is adjusted by the connecting rod 803, thereby changing the distance between the first limiting ring 804 and the second limiting ring 805.

[0092] Furthermore, the gas storage components include:

[0093] High-pressure tank 501 and negative-pressure tank 504 are both mounted on base 101.

[0094] Two third check valves 503 are provided at the end of the side wall of the hollow shaft 405, and both third check valves 503 are fixedly connected to the first hose 507.

[0095] Two gas supply pipes 502 are connected to a high-pressure tank 501 and a negative-pressure tank 504 respectively, and the two gas supply pipes 502 are connected to two first hoses 507 respectively.

[0096] Two solenoid valves 505 are connected to the high-pressure tank 501 and the negative-pressure tank 504 respectively, and both solenoid valves 505 are fixedly connected to the connecting pipes 506.

[0097] When the second piston 903 reciprocates along the hollow shaft 405, the volume of the space enclosed by the second piston 903 and the hollow shaft 405 periodically increases and decreases. When the volume of the space decreases, the gas in the space enters the high-pressure tank 501 through one of the sets of third one-way valves 503, first hoses 507 and gas delivery pipes 502, causing the gas pressure in the high-pressure tank 501 to rise. Conversely, when the volume of the space increases, the gas in the negative pressure tank 504 enters the space through another set of third one-way valves 503, first hoses 507 and gas delivery pipes 502, thereby causing the gas pressure in the negative pressure tank 504 to decrease.

[0098] Furthermore, the liquid supply assembly also includes:

[0099] The second check valve 404 is disposed through the end of the side wall of the cylinder 401.

[0100] The liquid extraction tube 402 is connected to the second check valve 404 at one end and to the storage component at the other end.

[0101] The first one-way valve 403 is located at the end of the cylinder body 401 and is connected to multiple bacteria injection components.

[0102] The annular plate 406 is fixedly sleeved on the hollow shaft 405, and the two third check valves 503 are both located between the annular plate 406 and the first piston 407.

[0103] Furthermore, the storage components include:

[0104] Storage tank 201 is fixed on base 101, and the liquid extraction pipe 402 is connected to storage tank 201;

[0105] Support 202 is fixed to the top of the inner wall of storage tank 201;

[0106] A rotating shaft 203 is rotatably mounted at the bottom of the storage tank 201, and the rotating shaft 203 is rotatably connected to the support 202. Multiple stirring rods 204 are fixedly sleeved on the rotating shaft 203.

[0107] Gear 207 is rotatably mounted at the bottom of storage tank 201, and gear 207 and rotating shaft 203 are fixed.

[0108] The connecting seat 206 is fixed to the bottom of the storage tank 201. The rack plate 205 is slidably connected to one side of the connecting seat 206, and the rack plate 205 and the gear 207 are engaged.

[0109] When the first piston 407 reciprocates along the cylinder 401, the volume of the space formed by the first piston 407 and the cylinder 401 increases and decreases periodically. When the volume of the space increases, the bacterial solution in the storage tank 201 enters the space through the extraction pipe 402 and the second one-way valve 404. When the volume of the space decreases, the bacterial solution in the space is output through the first one-way valve 403.

[0110] During the operation of the power unit, the rack plate 205 is driven to reciprocate, and the rack plate 205 drives the gear 207 to reciprocate, so that the rotating shaft 203 and the stirring rod 204 rotate, stirring the bacterial liquid in the storage tank 201 to make the mycelium evenly distributed.

[0111] During the reciprocating motion of the hollow shaft 405, the annular plate 406 is driven to move reciprocally. With the restriction of the annular plate 406 by the first limiting ring 804 and the restriction of the first piston 407 by the second limiting ring 805, the stroke of the hollow shaft 405 can be changed, thereby changing the stroke of the first piston 407. Since both third check valves 503 are located between the annular plate 406 and the first piston 407, during the movement of the hollow shaft 405, the first piston 407 and the annular plate 406 provide protection for the third check valves 503 and the first hose 507, preventing them from colliding with and being damaged by the first limiting ring 804.

[0112] Furthermore, the powertrain components include:

[0113] The transmission frame 303 is fixed at both ends to the rack plate 205 and the transmission rod 901, respectively.

[0114] Mounting bracket 102 is fixed to the top of base 101. A motor 103 is fixed to the top of mounting bracket 102. A turntable 301 is fixed to the output shaft of motor 103. A connecting rod 302 is rotatably arranged at one side of turntable 301, and the connecting rod 302 is rotatably connected to the transmission bracket 303.

[0115] Furthermore, the inoculation component includes:

[0116] An extrusion seat 602 is fixed to a fixing frame 601. A circular groove 603 is provided on the top of the extrusion seat 602, and a cavity 604 is provided inside the extrusion seat 602 below the circular groove 603.

[0117] The third piston 605 is slidably disposed in the circular groove 603. A spring 606 is provided at the bottom of the third piston 605, and the spring 606 is fixed to the inner wall of the bottom of the circular groove 603.

[0118] Injection tube 610 is fixed on the third piston 605 and penetrates the bottom of the third piston 605. The bottom end of injection tube 610 is a pointed structure.

[0119] The feed pipe 611 is fixed on the fixing frame 601 and is connected to the first one-way valve 403.

[0120] The second hose 612 has one end connected to the feed pipe 611 and the other end connected to the inoculation pipe 610.

[0121] Hollow rod 608 is fixed to the bottom inner wall of cavity 604, and the top of hollow rod 608 is fixed to the top inner wall of cavity 604. Injection tube 610 passes through hollow rod 608.

[0122] A connecting hole 613 is formed on the inner wall of the bottom of the circular groove 603, and the connecting hole 613 penetrates the cavity 604;

[0123] Multiple circular holes 609 are equidistantly and circularly formed on the inner wall of the bottom of the cavity 604;

[0124] The negative pressure pipe 607 is connected at one end to the cavity 604 and at the other end to the connecting pipe 506 near the negative pressure tank 504.

[0125] When cavity 604 is connected to negative pressure tank 504 via negative pressure pipe 607, cavity 604 is under negative pressure. In conjunction with the circular hole 609, the squeezing seat 602 can adsorb the plastic film on the mushroom bag. Through the connecting hole 613, the circular groove 603 is under negative pressure, so that the air pressure difference on both sides of the third piston 605 increases. Through the action of air pressure, the third piston 605 is pushed down along the circular groove 603, which drives the inoculation tube 610 down, so that the inoculation tube 610 pierces the plastic film of the mushroom bag, ready for inoculation.

[0126] Furthermore, the inoculation component also includes:

[0127] Sleeve 703 is disposed on the top of base 101. A fourth piston 705 is slidably disposed inside sleeve 703. A sleeve rod 706 is disposed on the top of the fourth piston 705.

[0128] Placement plate 701 is fixed to the top of sleeve rod 706. Placement plate 701 has an arc structure and is located below extrusion seat 602.

[0129] The tube body 704 penetrates the outer wall of the sleeve 703 and is located below the fourth piston 705. The tube body 704 is connected to the two connecting tubes 506.

[0130] Two telescopic rods 702 are installed on the top of the base 101, and the telescopic ends of the two telescopic rods 702 are fixed to the placement plate 701.

[0131] When the gas in the high-pressure tank 501 enters the sleeve 703 through the pipe body 704, it pushes the fourth piston 705 to rise, which in turn drives the placement plate 701 to rise through the sleeve rod 706, so that the mushroom bag on the placement plate 701 and the extrusion seat 602 come into contact, and the extrusion seat 602 extrudes small pits on the mushroom bag to facilitate the inoculation work.

[0132] During the ascent of the placement plate 701, the stability of the placement plate 701 can be ensured by the two telescopic rods 702 at the bottom of the placement plate 701.

[0133] The specific working method is as follows: pour the prepared auricularia auricula liquid into the storage tank 201, place the inoculation bag on the placement plate 701, turn on the switch of motor 103. Since the more inoculation bags there are, the more inoculation liquid can be injected at one time, the stroke of the first piston 407 is adjusted according to the number of inoculation bags.

[0134] When adjusting the stroke of the first piston 407, the operator first needs to rotate the transmission block 801 using tools such as a wrench. When the transmission block 801 rotates, it drives the threaded cylinder 802 to rotate. Through the first thread on the threaded cylinder 802 and the second thread inside the cylinder 401, the position of the threaded cylinder 802 is adjusted. When the threaded cylinder 802 moves, it drives the first limiting ring 804 to move through the connecting rod 803. The distance between the first limiting ring 804 and the second limiting ring 805 changes. By limiting the annular plate 406 with the first limiting ring 804 and the first piston 407 with the second limiting ring 805, the stroke of the hollow shaft 405 can be adjusted, thereby completing the stroke adjustment of the first piston 407.

[0135] When the motor 103 is working, it drives the turntable 301 to rotate. Since the end of the connecting rod 302 is located at the eccentric position of the turntable 301, the rotation of the turntable 301 drives the transmission frame 303 to reciprocate through the connecting rod 302.

[0136] During the reciprocating motion of the connecting rod 302, the rack plate 205 is driven to reciprocate along the connecting seat 206, and then the rotating shaft 203 is driven to reciprocate through the rack plate 205 and the gear 207. This, together with the stirring rod 204, stirs the auricularia auricula liquid in the storage tank 201 to ensure that the mycelium is evenly distributed, thereby ensuring the injection effect.

[0137] While the connecting rod 302 reciprocates, it drives the transmission rod 901 to reciprocate. During the movement of the transmission rod 901, the friction between the damping block 902 and the hollow shaft 405 drives the hollow shaft 405 to move, which in turn drives the first piston 407 to reciprocate in the cylinder 401. The reciprocating motion of the first piston 407 in the cylinder 401 will cause the volume of the space formed by the first piston 407 and the cylinder 401 to increase and decrease periodically.

[0138] When the volume of the space formed by the first piston 407 and the cylinder 401 increases, the air pressure inside the space decreases. Under the action of air pressure, the bacterial liquid in the storage tank 201 enters the space through the extraction pipe 402 and the second one-way valve 404. When the volume of the space formed by the first piston 407 and the cylinder 401 decreases, the bacterial liquid in the space enters the second hose 612 through the first one-way valve 403 and the feed pipe 611, and is then output through the injection pipe 610.

[0139] Since the diameter of the turntable 301 is fixed, the transmission through the connecting rod 302 and the transmission frame 303, and the fixed stroke of the transmission rod 901 and the damping block 902, will cause the first piston 407 to periodically contact the second limiting ring 805 and the annular plate 406 to periodically contact the first limiting ring 804. When the first piston 407 contacts the second limiting ring 805, as the transmission rod 901 continues to move, the second piston 903 will compress the gas in the space formed by the hollow shaft 405 and the second piston 903, causing the gas pressure in the space to rise. The gas will then pass through one of the sets of third one-way valves 503. The first hose 507 and the gas supply pipe 502 enter the high-pressure tank 501. As the working time increases, the gas pressure in the high-pressure tank 501 is in a high-pressure environment. Conversely, when the annular plate 406 abuts against the first limiting ring 804, as the transmission rod 901 continues to move, the volume of the space enclosed by the hollow shaft 405 and the second piston 903 increases. Then, the gas in the negative pressure tank 504 will be drawn into this space through the second piston 903, another set of gas supply pipes 502, the first hose 507, and the third one-way valve 503. Similarly, as the working time increases, the gas in the negative pressure tank 504 is in a low-pressure environment.

[0140] When performing the inoculation operation, first turn on the solenoid valve 505 on the high-pressure tank 501 and turn off the solenoid valve 505 on the negative pressure tank 504. The high-pressure gas in the high-pressure tank 501 enters the pipe body 704 through the solenoid valve 505 and its corresponding connecting pipe 506. The gas then enters the sleeve 703 through the pipe body 704 and is located in the space below the fourth piston 705. The gas pushes the fourth piston 705 to rise, which in turn pushes the placement plate 701 to rise through the sleeve rod 706, causing the inoculum bag on the placement plate 701 to rise until the inoculum bag touches the squeezing seat 602. The squeezing seat 602 then presses a small pit into the inoculum bag.

[0141] Then, turn on the solenoid valve 505 on the negative pressure tank 504 and turn off the solenoid valve 505 on the high pressure tank 501. The low pressure environment inside the negative pressure tank 504 causes the air pressure in the negative pressure pipe 607 and the pipe body 704 to drop rapidly. After the air pressure in the negative pressure pipe 607 drops, the air pressure in the cavity 604 also drops. At this time, the plastic film of the bacterial bag is adsorbed through the round hole 609, and the squeezing seat 602 and the plastic film are fixed. After the air pressure in the cavity 604 drops, the air pressure in the round groove 603 also drops through the connecting hole 613. Under the action of the air pressure difference on both sides of the third piston 605, the third piston 605 drops, compresses the spring 606, and at the same time drives the bacterial injection tube 610 to drop, so that the bacterial injection tube 610 can extend out of the squeezing seat 602, puncture the plastic film, and prepare for bacterial injection.

[0142] As the inoculation tube 610 extends out of the squeezing seat 602, the air pressure in the sleeve 703 below the fourth piston 705 decreases, causing the fourth piston 705 to descend. This, in turn, causes the spawn bag to descend via the sleeve rod 706 and the placement plate 701. When the spawn bag descends, the plastic film adsorbed by the bottom hole 609 of the squeezing seat 602 remains fixed. Therefore, the plastic film at the small pit on the spawn bag separates from the culture medium inside the spawn bag. At this time, the end of the inoculation tube 610 is in the space formed by the small pit and the plastic film. Therefore, the auricularia auricula-judae broth is introduced into this space by the inoculation tube 610, completing the entire inoculation process.

[0143] When the solenoid valve 505 on the negative pressure tank 504 is closed, the gas inside the spawn bag enters the gap between the spawn bag and the compression seat 602 through the puncture point of the injection tube 610. It then enters the circular groove 603, located below the third piston 605, through the gap between the hollow rod 608 and the injection tube 610. Finally, it enters the cavity 604 through the connecting hole 613, causing the circular hole 609 to lose its ability to adhere to the plastic film. Combined with gravity, the spawn bag detaches from the bottom of the compression seat 602 and is removed from the placement plate 701. After the spawn bag and compression seat 602 are separated, external gas enters the cavity 604 and the circular groove 603 through the circular hole 609 and the connecting hole 613. At this time, the compressed spring 606 resets, causing the third piston 605 to reset, which in turn causes the injection tube 610 to enter the hollow rod 608, preparing for the injection of the next spawn bag.

[0144] It is worth noting that: by using an automated robot to supply the substrate to the substrate bags, in conjunction with this device, the automated inoculation of the substrate bags can be completely realized. However, the automated feeding and unloading robots are existing technologies and are not the subject of this invention, so they will not be described further in this invention.
