Description

Technical Field

[0001] This application relates to the technical field of edible fungi inoculation, and in particular to an inoculation device for auricularia auricula-judae mushroom bags. Background Technology

[0002] *Auricularia auricula-judae* is a fungus belonging to the family Auriculariaceae and the genus *Auricularia*. The basidiosperm is large, hemispherical to irregularly shaped, and massive, generally brain-like to divided into several deeply grooved and thick lobes, 3-12 cm in diameter and 2-8 cm high. The hymenium is widespread on the exposed surface, forming a broad, loose area containing the basidia; the probasididia are initially elliptical to ovoid; the mature hypobasididia are globose, nearly globose, rarely pear-shaped to have a short stalk-like base, 13-25 μm long and 11.5-19.5 picometers wide.

[0003] In existing technologies, some small-scale or manual inoculation operations use syringe-like devices, with needles typically being long and thin metal needles. Some inoculations into the *Auricularia auricula-judae* bags are performed manually, relying on experience to select the inoculum. This can lead to over- or under-inoculation in some bags. However, these methods still have some problems. For example, the metal needles are too hard; rigid insertion and squeezing can directly damage the mycelial structure. Inserting the needles into the bag can easily squeeze or scratch the mycelium. Squeezing can cause cell wall rupture and cytoplasm leakage, resulting in the death of some mycelia. Scratching disrupts the continuous growth chain of the mycelium, breaking the normally rapidly spreading mycelial network into fragmented pieces. Furthermore, excessive inoculation wastes mycelial resources, while insufficient inoculation prevents the mycelium from quickly forming a dominant colony and rapidly occupying the living space within the bag.

[0004] Therefore, in order to solve the above problems, this application provides a device for inoculating auricularia auricula-judae bags. Utility Model Content

[0005] To address the problem that rigid metal needles can directly damage mycelial structures during insertion and compression, and that inserting them into mushroom bags can easily squeeze and scratch the mycelium, causing cell wall rupture, cytoplasm leakage, and death of some mycelia, while scratching can disrupt the continuous growth chain of mycelia, breaking the originally rapidly spreading mycelial network into fragmented pieces, this application provides an inoculation device for *Auricularia auricula-judae* mushroom bags.

[0006] This application provides an inoculation device for *Auricularia auricula-judae* bags, comprising a support frame and an inoculation device, wherein the inoculation device includes:

[0007] An inoculation box is fixedly connected to the top of the support frame. Sealing plates are slidably connected to both sides of the inoculation box. A storage groove is opened through the top of the inoculation box near both sides of the sealing plates. The sealing plates and the storage groove are slidably engaged. A seed delivery tube is provided at the top of the inner cavity of the inoculation box. An inoculation needle is connected to the bottom of the seed delivery tube. An elastic sealing valve is provided between the bottom of the seed delivery tube and the inoculation needle. A spiral blade is rotatably connected to the inner cavity of the seed delivery tube. A seed storage box is fixedly connected to one side of the inoculation box. A seed pump is fixedly connected to the top of the seed storage box. The seed pump is connected to the inside of the seed storage box through a seed pumping pipe. A delivery pipe is connected to one end of the seed pump. The delivery pipe passes through the inoculation box and is connected to the bottom of one side of the seed delivery tube. A solenoid valve is provided at the end of the delivery pipe near the seed delivery tube.

[0008] The inoculation box is equipped with a drive device on both sides.

[0009] Preferably, the inoculation needle is made of soft silicone material, and the needle tip has a tapered oblique cut.

[0010] Preferably, a second motor is fixedly connected to the top of the seed delivery cylinder, and the output end of the second motor is fixedly connected to the top end of the spiral blade.

[0011] Preferably, a connecting frame is fixedly connected to the top of the seed delivery tube, and a receiving groove is provided through the top wall of the inoculation box, with the connecting frame adapted to the receiving groove.

[0012] Preferably, an electric push rod is fixedly connected to the top of the inoculation box, and the output end of the electric push rod is fixedly connected to the top of the connecting frame.

[0013] Preferably, a seed inlet pipe is connected to one side of the seed storage box, and a valve is provided on the seed inlet pipe.

[0014] Preferably, a conveyor belt is provided on the top of the support frame, a drive roller is rotatably connected to one side of the support frame, a driven roller is rotatably connected to the other side of the support frame, a motor is fixedly connected to one side of the support frame, and the output end of the motor is fixedly connected to one end of the drive roller.

[0015] Preferably, the driving device includes:

[0016] The inoculation box has through grooves on both sides near the sealing plate. A slider is fixedly connected in each of the two grooves. One side of each of the two adjacent sliders is fixedly connected to one side of the sealing plate. A screw is rotatably connected in one of the grooves, passing through one of the sliders and threadedly connected to it. A limit rod is fixedly connected in the other groove, passing through another slider and slidingly engaged with it. A motor is fixedly connected to the top of the inoculation box, and the output end of the motor is fixedly connected to the top of the screw via a coupling.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, the device features two sealing plates. After the mushroom bag enters the inoculation box, the sealing plates descend to the bottom, forming a completely enclosed space. This isolates the inoculation process from the external open environment, preventing airborne spores (such as Penicillium and Aspergillus) from falling into the opening of the mushroom bag or the inoculation site. The inoculation needle is made of soft silicone, which can deform slightly with pressure when inserted into the mushroom bag, avoiding the rigid compression and scratching of the auricularia auricula mycelium caused by traditional metal needles. Furthermore, the electromagnetic valve and spiral blade, along with the elastic sealing valve and the inoculation tube, enable quantitative delivery, avoiding growth differences caused by excessive inoculation (intense nutrient competition) or insufficient inoculation (difficulty for mycelium to quickly occupy space). This also avoids waste of inoculum due to over-inoculation and can significantly reduce raw material costs in the long run.

[0019] In this invention, the device automatically conveys via a conveyor belt, and the sealing plate is linked with the inoculation action to form a continuous process, which greatly reduces labor intensity and cost. At the same time, the electric push rod pushes the inoculation tube to move precisely to the bottom, ensuring that the needle is inserted into the mushroom bag at a consistent depth, avoiding the problem of uneven depth during manual inoculation, so that the inoculum can contact the culture medium evenly and the colonization is more stable.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, such as Figure 1-5As shown, this utility model provides an inoculation device for *Auricularia auricula-judae* bags, including a support frame 1, an inoculation device, and a driving device. The inoculation device includes: an inoculation box 4 fixedly connected to the top of the support frame 1; sealing plates 10 slidably connected to both sides of the inoculation box 4; a receiving groove penetrating the top of the inoculation box 4 near both sides of the sealing plates 10; the sealing plates 10 slidingly engaging with the receiving groove; a seed delivery cylinder 15 disposed at the top of the inner cavity of the inoculation box 4; an inoculation needle 16 connected to the bottom of the seed delivery cylinder 15; the inoculation needle 16 being made of soft silicone material; the needle tip of the inoculation needle 16 having a tapered oblique cut; an elastic sealing valve disposed between the bottom of the seed delivery cylinder 15 and the inoculation needle 16, which can slightly deform when inserted into the bag to reduce compression of the mycelium; a spiral blade rotatably connected to the inner cavity of the seed delivery cylinder 15; and a second motor 20 fixedly connected to the top of the seed delivery cylinder 15, with the output end of the second motor 20 connected to the spiral blade. The top of the inoculation box 4 is fixedly connected to the seed storage box 5. The top of the seed storage box 5 is fixedly connected to the seed pump 7. The seed pump 7 is connected to the inside of the seed storage box 5 through the seed pump pipe 6. One end of the seed pump 7 is connected to the delivery pipe 13, which passes through the inoculation box 4 and is connected to the bottom of one side of the seed delivery cylinder 15. The end of the delivery pipe 13 near the seed delivery cylinder 15 is equipped with a solenoid valve 19. The top of the seed delivery cylinder 15 is fixedly connected to the connecting frame 17. The top wall of the inoculation box 4 is provided with a receiving groove. The connecting frame 17 is adapted to the receiving groove. The top of the inoculation box 4 is fixedly connected to the electric push rod 8. The output end of the electric push rod 8 is fixedly connected to the top of the connecting frame 17. One side of the seed storage box 5 is connected to the seed inlet pipe 18, which is equipped with a valve to transport the auricularia auricula var. thunbergii spawn into the seed storage box 5. The top of the support frame 1 is equipped with a conveyor belt 2.

[0029] In this embodiment, the *Auricularia auricula-judae* spawn bag is placed on the conveyor belt 2 for transport. Then, the drive device on one side is activated, causing the sealing plate 10 to enter the receiving slot, allowing the *Auricularia auricula-judae* spawn bag to enter the inoculation box 4. The drive device is then activated again, causing the sealing plate 10 to descend to the bottom and seal the inside of the inoculation box 4. Then, the seed pump 7 and the solenoid valve 19 are activated, and the spawn is transported to the inoculation tube 15 through the delivery pipe 13 for quantitative delivery. Then, the electric push rod 8 is activated, pushing the connecting frame 17 and the inoculation tube 15 to the bottom, allowing the inoculation needle 16 to be inserted into the *Auricularia auricula-judae* spawn bag. The inoculation needle 16 is made of soft silicone to avoid scratching and squeezing the spawn. Then, the motor 9 and the elastic sealing valve are activated, and the motor drives the spiral blade to rotate, allowing the spawn to enter the inoculation tube 15, instantly injecting the *Auricularia auricula-judae* spawn into the spawn bag. After injection, the drive device on the other side is activated, and the conveyor belt 2 carries the *Auricularia auricula-judae* spawn bag out of the inoculation box 4.

[0030] Example 2, as Figure 1-5As shown, the number of driving devices is set to two, and the driving devices are set on both sides of the inoculation box 4. The driving devices include: a sliding groove through which the inoculation box 4 is opened on both sides near the sealing plate 10, and a slider 12 is fixedly connected in each of the two sliding grooves. One side of each of the two adjacent sliders 12 is fixedly connected to one side of the sealing plate 10. A screw 11 is rotatably connected in one of the sliding grooves. The screw 11 passes through one of the sliders 12 and is threadedly connected to one of the sliders 12. A limit rod 14 is fixedly connected in the other sliding groove. The limit rod 14 passes through another slider 12 and is slidably engaged with another slider 12. A motor 9 is fixedly connected to the top of the inoculation box 4. The output end of the motor 9 is fixedly connected to the top end of the screw 11 through a coupling. A drive roller 21 is rotatably connected to one side of the support frame 1. A driven roller 22 is rotatably connected to the other side of the support frame 1. A motor 3 is fixedly connected to one side of the support frame 1. The output end of the motor 3 is fixedly connected to one end of the drive roller 21.

[0031] In this embodiment, the second motor 20 is started, which drives the screw 11 to rotate. The screw 11 drives one of the sliders 12 to move up and down. One of the sliders 12 drives the sealing plate 10 and the other slider 12 to move up and down on the limiting rod 14, which can drive the sealing plates 10 on both sides to move up and down. The motor 3 drives the active roller 21 to rotate, which drives the conveyor belt 2 to rotate. The conveyor belt 2 drives the driven roller 22 to rotate, thereby driving the conveyor belt 2 to move the auricularia auricula-judae bag.

[0032] Working principle: When in use, start motor 20. Motor 20 drives screw 11 to rotate. Screw 11 drives one slider 12 to move up and down. One slider 12 drives sealing plate 10 and the other slider 12 to move up and down on limit rod 14, thus moving the sealing plates 10 on both sides up and down. Motor 3 drives drive roller 21 to rotate, which in turn drives conveyor belt 2 to rotate. Conveyor belt 2 drives driven roller 22 to rotate, thereby moving the auricularia auricula-judae bag. Then, start the drive device on one side, causing the sealing plate 10 to enter the receiving trough, allowing the auricularia auricula-judae bag to enter the inoculation box 4. Then, the drive device is started, causing the sealing plate 10 to descend to the bottom and seal the inside of the inoculation box 4. Then, the seed pump 7 and the solenoid valve 19 are started, and the inoculum is transported to the inoculation tube 15 through the delivery pipe 13. Then, the electric push rod 8 is started, and the electric push rod 8 pushes the connecting frame 17 and the inoculation tube 15 to the bottom, so that the inoculation needle 16 is inserted into the inside of the auricularia auricula-judae spawn bag. Then, the motor 9 and the elastic sealing valve are started, and the motor drives the spiral blade to rotate, so that the inoculum enters the inoculation tube 15 and injects the auricularia auricula-judae spawn into the spawn bag instantly. After the injection is completed, the drive device on the other side is started, and the conveyor belt 2 carries the auricularia auricula-judae spawn bag out of the inoculation box 4.
