Edible mushroom inoculation device and method of use

Abstract

This invention relates to the field of edible fungi inoculation technology, specifically to an edible fungi inoculation device and its usage method. The device comprises an inoculation shell, a liquid culture storage cylinder, a segmented drive shaft, an adjustable piston arm, a spacing adjustment arm, an extension injection tube, an input control groove, and an injection protective sleeve. The drive motor within the segmented drive shaft drives the output shaft to rotate at the same speed via the input shaft, symmetrical extension hinge seat, inclined plate, and inclined column. Simultaneously, the inclined column oscillates, and the oscillation amplitude is rapidly adjusted by the spacing adjustment arm through a two-stage bistable mechanism. This controls the stroke of the piston head of the adjustable piston arm within the extraction sleeve, achieving quantitative stepless extraction. The extension injection tube is propelled unidirectionally by the piston reciprocating through the inclined path groove driven by the side gripper. Simultaneously, the conical shell uses a spiral cutting edge to create a smooth channel, and the movable injection head opens laterally to complete the closed injection. The entire machine is driven by a single motor, is fully sealed, and operates with low noise. It can complete deep-hole quantitative inoculation in one pass, significantly reducing contamination by other microorganisms and labor intensity.

Description

Technical Field

[0001] This invention relates to the field of edible fungi inoculation technology, specifically to an edible fungi inoculation device and its usage method. Background Technology

[0002] Inoculation of edible fungi is a crucial step in introducing superior pure spawn into a culture medium or log under aseptic conditions. When liquid spawn is inoculated into the substrate, it is often impossible to inject the required amount precisely, and the injection port is easily blocked by substances in the substrate, making it difficult for workers to clean. This results in high labor intensity, long inoculation time, and low work efficiency.

[0003] Existing inoculation devices generally rely on manual pushing and pulling or a single piston stroke for quantitative control, making it impossible to steplessly adjust the dosage according to differences in strains and substrates. This results in large errors in the inoculation amount within the same batch, with the mother culture stage prone to contamination due to overgrowth and the primary culture stage prone to gaps due to insufficient growth, leading to significant fluctuations in the yield. Furthermore, traditional devices with fixed straight-hole needles at the front end experience high resistance when inserted into lignified or fibrous culture media, requiring repeated shaking for puncture. The hole walls are rough and prone to clogging, causing the bacterial solution to flow back along the needle path, resulting in a wet and sticky bottle mouth, wasting the strain and becoming an entry point for mold. At the same time, the negative pressure backflow during needle withdrawal brings external bacteria into the bag, resulting in a persistently high contamination rate.

[0004] In view of this, we propose an edible fungi inoculation device and its usage method. Summary of the Invention

[0018] An edible fungus inoculation device and its usage method, comprising the following steps:

[0019] S1. The drive motor drives the input shaft to rotate at a constant speed. The symmetrically arranged extended hinge seats, inclined plates, and inclined columns transmit the rotation at the same speed and in the same direction to the output shaft. At the same time, the inclined column swings with the inclined plate. The swing amplitude is determined by the axial distance between the two extended hinge seats. The swing column drives the piston head to reciprocate linearly in the extraction sleeve through the piston connecting arm, rotating mounting seat, and piston hinge arm, forming a variable stroke quantitative extraction. The stroke size is positively correlated with the tilt angle of the inclined column, realizing the quantitative suction of the liquid bacteria storage cylinder to the fixed input tank through the one-way input valve.

[0020] S2. The connecting ring moves axially synchronously with the extended hinge seat; the two inclined connecting arms are tightened by tension springs, and form a bistable mechanism with the limit rotating arm, the arm connecting shaft and the pull-down switching plate; when the pull-down switching plate is pressed, the limit rotating arm instantly flips from the horizontal collinear state to the bottom of the shaft limit groove, and the distance between the inclined connecting arms switches between the two levels, thereby synchronously changing the tilt angle of the inclined column, the piston head stroke and the single extraction volume, realizing the rapid selection of the "large" and "small" dose levels;

[0021] S3. When the piston head reciprocates, the driven pull rod synchronously pushes and pulls the connecting slider; the inclined path groove drives the side gripper to radially clamp or release through the driven connecting column; the fixed tube rotates in place with the output shaft via the driven rotating shaft; when the side gripper clamps the extension tube, it pushes it out in one direction, and releases it during the return stroke, and the extension tube maintains its outward extension length, realizing deep hole propulsion of "rotation plus intermittent outward extension", and the needle roller ensures that the rotation and axial movement do not interfere with each other;

[0022] S4. When the extension collar is limited by the travel limit seat, the angle between the movable hinge arm and the fixed hinge arm decreases, and the lifting column lifts the inner sliding tube along the transverse slide groove. After the inner sliding tube is lifted, the original input side check valve disengages from the interaction groove and stops aspiration, while the other side check valve opens, and the entire buffer bacterial solution in the extraction sleeve is switched to injection mode, realizing automatic switching between "aspiration and injection". After the extension tube stops advancing, the movable injection head continues to move forward relative to the injection mounting seat, and the oblique injection groove is exposed. At the same time, the inner hinge arm and the outer hinge arm open the conical shell, and the bacterial solution is injected laterally along the oblique injection groove into the smooth channel pre-cut by the spiral cutting edge, completing the sealing, directional, and quantitative inoculation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In this invention, the combined action of a segmented drive shaft and an adjustable piston arm enables the conversion of liquid bacteria into a composite motion of rotation, oscillation, and linear motion. Only one drive motor is needed to simultaneously complete power output and stroke adjustment, simplifying the transmission chain and improving energy efficiency. The oscillation amplitude corresponds to the tilt angle of the inclined column in real time, allowing the piston head to adjust its stroke within the extraction sleeve, thereby adjusting the single extraction volume.

[0025] In this invention, the three parameters of "dose-extension length-absorption stop switching" are linked by the joint action of the spacing adjustment arm and the input control slot. Pulling down the switching plate once can quickly switch between two dose levels and automatically correspond to the maximum extension limit of the extension tube and the liquid aspiration stop, ensuring that the inoculation volume matches the well depth each time without additional operation, greatly reducing waste and improving experimental repeatability.

[0026] In this invention, the combined action of the extended injection tube and the injection protective sleeve achieves a closed loop of "rotational cutting - unidirectional propulsion - lateral injection". The conical shell first uses a spiral cutting edge to create a smooth channel, then the side grippers push the extended tube into place in a unidirectional direction, and finally the movable injection head opens laterally to complete the closed injection. This significantly reduces resistance, minimizes bacterial backflow, and improves the success rate of deep-well inoculation. The spiral cutting edge converts static friction into rolling friction, enabling one-time pore creation even on lignified culture media. The lateral angled injection groove is always covered by the injection mounting base before withdrawal to avoid blockage and prevent the intrusion of external bacteria. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please see Figures 1 to 25 The present invention provides a technical solution: an edible fungus inoculation device, comprising an inoculation shell 1, a liquid fungus storage cylinder 11 fixedly connected to the top surface of the inoculation shell 1, an injection shell 12 fixedly connected to the outer surface of the inoculation shell 1, a control handle 13 fixedly connected to the bottom surface of the inoculation shell 1, a segmented drive shaft 2 provided on the inner surface of the inoculation shell 1, an adjustable piston arm 3 provided on the outer surface of the segmented drive shaft 2, a spacing adjustment arm 4 provided on the outer surface of the segmented drive shaft 2, an extension injection tube 5 provided at one end of the segmented drive shaft 2, an input control groove 6 provided on the outer surface of the adjustable piston arm 3, and an injection protective sleeve 7 provided on the outer surface of the extension injection tube 5.

[0055] The inoculation shell 1 is used to install and protect the internal components. When injection is required, the injection shell 12 is aligned with the required injection stick, and the subsequent extension injection tube 5 will extend from the inside. The liquid bacteria storage cylinder 11 is connected to the input control slot 6 to buffer and passively output the liquid bacteria.

[0056] The segmented drive shaft 2 includes a drive motor 21, which is fixedly connected to the outer surface of the inoculation shell 1. The output end of the drive motor 21 is fixedly connected to an input shaft 22. One end of the input shaft 22 is slidably connected to an extension hinge seat 23. One end of the extension hinge seat 23 is hinged to an extension column 231. One end of the extension hinge seat 23 is fixedly connected to an inclined plate 24. An inclined column 241 is fixedly connected to the outer surface of the inclined plate 24. The other end of the inclined column 241 is fixedly connected to an output shaft 25 through the inclined plate 24 and the extension hinge seat 23. A fixed input groove 251 is rotatably connected to the outer surface of the output shaft 25.

[0057] The input shaft 22 is rotatably connected to the inner surface of the inoculation shell 1, the extension column 231 is slidably connected to the inner surface of the input shaft 22, and there are two extension hinge seats 23, two extension columns 231, and two inclined plates 24, which are symmetrically distributed on both sides of the inclined column 241. The extension hinge seats 23 on both sides are fixedly connected to the input shaft 22 and the output shaft 25, respectively. The axes of the input shaft 22 and the output shaft 25 are collinear, and the fixed input groove 251 is fixedly connected to the inner surface of the inoculation shell 1.

[0058] With the segmented drive shaft 2, during use, the drive motor 21 acts as the drive source to control the input shaft 22 to rotate at a constant speed. The input shaft 22 is connected to the output shaft 25 on the other side through the extended hinge seat 23, the inclined plate 24 and the inclined column 241. Since the axes of the input shaft 22 and the output shaft 25 are collinear, the fixed structure on the middle part, which is equivalent to a rod, will not affect the rotation of the output shaft 25. Therefore, the input shaft 22 and the output shaft 25 rotate in the same direction and at the same speed.

[0059] As the input shaft 22 rotates, the intermediate extension hinge seat 23, the inclined plate 24 and the inclined column 241 also rotate. The rotation of the inclined plate 24 will change the angle of the inclined column 241, thereby driving the adjustable piston arm 3 to swing back and forth for extraction.

[0060] The swing amplitude of the tilt column 241 is controlled by its deflection angle. The extension hinge seat 23 can slide and extend or shorten within the input shaft 22 through the extension column 231. When both sides of the extension hinge seat 23 move inward or outward at the same time, they will push the tilt plate 24 to change the tilt angle of the extension column 231. When the tilt column 241 is horizontal, it no longer swings. That is, the swing amplitude is positively correlated with the tilt angle of the tilt column 241.

[0061] The extension hinge seat 23 can rotate by hinge on the extension post 231, thereby adapting to the new connection position after the extension post 231 rotates.

[0062] Since the rotational speed of the output shaft 25 is only related to the rotational speed of the input shaft 22, the rotational speed of the tilting column 241 remains constant when adjusting the extension and retraction stroke of the adjustable piston arm 3.

[0063] The adjustable piston arm 3 includes a piston connecting arm 31, which is rotatably connected to the outer surface of the inclined column 241. One end of the piston connecting arm 31 is fixedly connected to a rotating mounting base 32. The outer surface of the rotating mounting base 32 is hinged to a piston hinge arm 33. The other end of the piston hinge arm 33 is hinged to a piston head 331. The outer surface of the piston head 331 is slidably connected to a pull-out sleeve 34. The bottom surface of the pull-out sleeve 34 is fixedly connected to a one-way input valve 35. The other end of the one-way input valve 35 is fixedly connected to an input block 351.

[0064] The extraction sleeve 34 is fixedly connected to the inner surface of the inoculation shell 1, and the input card block 351 is fixedly connected to the inner surface of the fixed input groove 251.

[0065] With the adjustable piston arm 3, during use, the piston connecting arm 31 is rotatably connected to the inclined column 241, so the connection position remains unchanged but it can rotate at the connection point. Therefore, it will not follow the inclined column 241 in rotation, but when the inclined column 241 is tilted, it will swing, thereby driving the piston connecting arm 31 to swing back and forth.

[0066] The piston connecting arm 31 is connected to the piston head 331 via the rotating mounting base 32 and the piston hinge arm 33. The piston head 331 reciprocates and extends within the extraction sleeve 34 to extract bacterial liquid and output it to the subsequent parts.

[0067] Depending on the tilt angle of the tilt column 241, the stroke of the piston connecting arm 31 varies with each extension and retraction. The smaller the tilt angle, the smaller the stroke, and the less bacterial liquid is collected each time. The liquid is then input into the fixed input slot 251 through the one-way input valve 35 and the input card block 351 to continue outputting to the rear.

[0068] The spacing adjustment arm 4 includes a connecting ring 41, which is rotatably connected to the extension hinge seat 23. Inclined connecting arms 42 are fixedly connected to both sides of the connecting ring 41, and a travel limit seat 421 is fixedly connected to the outer surface of one of the inclined connecting arms 42. A limit rotating arm 43 is hinged to the outer surface of the inclined connecting arm 42. A side locking block 431 is fixedly connected to the outer surface of the limit rotating arm 43. An arm connecting shaft 432 is rotatably connected to the inner surface of the limit rotating arm 43. A tension spring 44 is rotatably connected to the outer surface of the inclined connecting arm 42. A pull-down switching plate 45 is rotatably connected to the outer surface of the arm connecting shaft 432. A shaft limiting groove 451 is fixedly connected to the inner surface of the inoculation shell 1.

[0069] There are two connecting rings 41, which are symmetrically distributed. The limiting rotating arms 43 are symmetrically distributed and hinged to each other. The side locking blocks 431 on both sides are in contact with each other. The arm connecting shaft 432 passes through the limiting rotating arms 43 on both sides. The two ends of the tension spring 44 are rotatably connected to the inclined connecting arms 42 at both ends respectively. The tension spring 44 passes through the rotation center of the limiting rotating arm 43. The pull-down switching plate 45 passes through to the outer surface of the inoculation shell 1. The shaft limiting groove 451 is slidably connected to the arm connecting shaft 432.

[0070] With the setting of the spacing adjustment arm 4, during use, the connecting ring 41 is connected to the extension hinge seat 23. Without affecting the extension hinge seat 23, the position of the extension hinge seat 23 is adjusted laterally. The connecting rings 41 on both sides are connected to the extension hinge seats 23 on the input shaft 22 and the output shaft 25 respectively. The connecting rings 41 on both sides are connected by the tilting connecting arm 42. When the push-pull arm connects to the shaft 432, the tilting connecting arm 42 will be pulled down or raised at the same time. Then the tilting connecting arm 42 will move inward or outward at the same time, thereby achieving the effect of adjusting the spacing of the extension hinge seat 23 to control the rotation angle of the tilting column 241.

[0071] The limiting rotating arm 43 needs to rotate around the hinge point with the inclined connecting arm 42 in order to adjust the distance between the inclined connecting arms 42. The inclined connecting arms 42 are connected by a tension spring 44. When the distance between the inclined connecting arms 42 increases, the tension spring 44 will generate an inward pulling force to reduce the distance between the inclined connecting arms 42. Only when the limiting rotating arms 43 are horizontally collinear, the rotating connection point between the limiting rotating arms 43 is collinear with the tension spring 44. At this time, the tension spring 44 cannot generate torque to maintain the current state. When the limiting rotating arm 43 is pulled slightly by the pull-down switching plate 45 and bends, the tension spring 44 will instantly return to its original position. However, since the arm connecting shaft 432 can only move up and down within the shaft limiting groove 451, the limiting rotating arm 43 can only descend to the bottom of the shaft limiting groove 451 at most. Thus, the limiting rotating arm 43 has only two states: horizontal and bent and descended to the bottom. Therefore, the tilting connecting arm 42 controls the rotation angle of the tilting column 241 in only two ways, realizing two-level adjustment.

[0072] The extended injection tube 5 includes a fixed tube 51, which is rotatably connected to the fixed input groove 251. A driven rotating shaft 511 is fixedly connected to the inner surface of the fixed tube 51. An extended tube 52 is slidably connected to the outer surface of the fixed tube 51. An extended collar 521 is fixedly connected to the outer surface of the extended tube 52. A driven pull rod 53 is fixedly connected to one end of the piston head 331. A connecting slider 54 is fixedly connected to one end of the driven pull rod 53. A symmetrically distributed oblique path groove 541 is opened on the outer surface of the connecting slider 54. A driven connecting post 542 is slidably connected to the inner surface of the oblique path groove 541. A side gripper 55 is fixedly connected to the bottom surface of the driven connecting post 542. A needle roller 551 is rotatably connected to the inner surface of the side gripper 55.

[0073] The driven shaft 511 is fixedly connected to the outer surface of the output shaft 25. The outer wall of the fixed tube 51 and the inner wall of the extension tube 52 are both hexagonal in cross section. The driven pull rod 53 is slidably connected to the inner surface of the extraction sleeve 34. The number of driven connecting posts 542 and side clamps 55 are both two and symmetrically distributed. The needle roller 551 is in contact with the outer surface of the extension tube 52.

[0074] By extending the injection tube 5, during use, the fixed tube 51 is connected to the output shaft 25 through the driven rotating shaft 511 and only rotates in place. The extension tube 52 is sleeved on the outside of the fixed tube 51, rotates with the fixed tube 51, and can slide on the surface of the fixed tube 51.

[0075] During the reciprocating motion of the piston head 331 to extract bacterial solution, it also drives the driven lever 53 to reciprocate. The driven lever 53 is connected to the side gripper 55 via the connecting slider 54. When the connecting slider 54 moves, it pushes the driven connecting column 542 to move through the inclined path groove 541, and then pushes the side gripper 55. Since the inclined path groove 541 is inclined, when it moves towards the injection shell 12, the inclined path groove 541 is equivalent to the driven connecting column 542 tightening inward. The side gripper 55 will also clamp inward and push out the extension tube 52. When the connecting slider 54 returns, the driven connecting column 542 pushes outward, and the side gripper 55 will not drive the extension tube 52 back, thus achieving the effect of making the extension tube 52 move forward in one direction.

[0076] The extension tube 52 is in contact with the internal needle roller 551. The rotation direction of the needle roller 551 is the same as that of the extension tube 52, so it will not affect the radial rotation of the extension tube 52, but it will increase friction when moving axially.

[0077] The input control slot 6 includes a fixed hinge arm 61, which is hinged to the outer surface of the travel limit seat 421. A movable hinge arm 611 is hinged to the outer surface of the fixed hinge arm 61. A lifting column 62 is rotatably connected to the connection between the fixed hinge arm 61 and the movable hinge arm 611. A transverse sliding groove 621 is provided on the top surface of the lifting column 62. An input housing 63 is fixedly connected to the top surface of the extraction sleeve 34. A lifting sliding groove 631 and an interactive groove 632 are provided on the outer surface of the input housing 63. An inner sliding tube 64 is slidably connected to the inner surface of the input housing 63. Lifting connecting columns 641 are fixedly connected to both sides of the inner sliding tube 64. An inner mounting plate 65 is fixedly connected to both sides of the inner sliding tube 64. A one-way valve 651 is provided on the outer surface of the inner mounting plate 65.

[0078] The lifting column 62 and the transverse slide 621 are symmetrically distributed on both sides of the input housing 63. The lifting slide 631 and the interactive groove 632 are also symmetrically distributed. The lifting connecting column 641 is slidably connected to the inner surface of the lifting slide 631. The lifting connecting column 641 is slidably connected to the transverse slide 621. The one-way valve 651 is at opposite heights on the mounting plates on both sides.

[0079] By setting the input control slot 6, during use, the fixed hinge arm 61 and the movable hinge arm 611 are connected to the travel limit seat 421 and in contact with the extension collar 521, respectively. Therefore, the movable hinge arm 611 will be pushed by the extension collar 521 on the extension tube 52 during operation, while the travel limit seat 421 is fixed on the surface of the inclined connecting arm 42. After the spacing of the inclined connecting arm 42 is adjusted, the position remains unchanged.

[0080] If the extension collar 521 comes into contact with the stroke limit seat 421 while moving with the extension tube 52, it will be stuck and unable to move forward. The stroke limit seat 421 is connected to the inclined connecting arm 42, and its position is affected by the inclined connecting arm 42. That is, when the inclined connecting arms 42 are close to each other, the angle of the inclined column 241 decreases, the stroke of the piston head 331 is shortened and the extraction amount decreases, and the maximum moving distance of the extension tube 52 is limited and reduced by the stroke limit seat 421. Conversely, the extraction amount increases, the extension tube 52 moves a longer distance, and can hold more bacterial liquid inside, so that the total amount of bacterial liquid extracted and the extraction efficiency change synchronously, so the total time remains unchanged.

[0081] Furthermore, when the travel limit seat 421 and the extension collar 521 approach each other, the movable hinge arm 611 and the fixed hinge arm 61 are squeezed together, the connection point is lifted upward, the lifting column 62 and the transverse slide 621 are lifted, and the lifting connecting column 641 is lifted to lift the inner sliding tube 64 from the input housing 63.

[0082] In the initial state, the inner sliding tube 64 is at the bottom of the input housing 63. At this time, the one-way valve 651 on the side near the liquid bacteria storage cylinder 11 is exposed from the interactive groove 632 on that side. When the piston head 331 is pulled out, the liquid bacteria in the liquid bacteria storage cylinder 11 is drawn into the extraction sleeve 34 through the one-way valve 651 and output to the input card block 351 through the one-way input valve 35.

[0083] When the inner sliding tube 64 is lifted off the input housing 63, the one-way valve 651, which was originally used for inputting liquid bacteria, is lifted off the interaction groove 632 and no longer interacts with the inside of the liquid bacteria storage cylinder 11. The extraction of liquid bacteria stops, and the one-way valve 651 on the other side is exposed from the interaction groove 632 on the other side. At this time, when the piston head 331 continues to move, it will no longer extract liquid bacteria, but will continue to push the internal liquid bacteria toward the side of the extension tube 52 for output.

[0084] This way, once the injection area is reached, the infusion of liquid bacteria is stopped, preventing the liquid bacteria already buffered inside from increasing further, thus facilitating quantification.

[0085] The transverse slide 621 is used to accommodate different positions of the travel limit seat 421 after it moves and connects with the lifting connecting column 641.

[0086] The injection protective sleeve 7 includes an injection mounting base 71, which is fixedly connected to the outer surface of the extension tube 52. A movable injection head 72 is slidably connected to the inner surface of the injection mounting base 71. An oblique injection groove 721 is formed on the outer surface of the movable injection head 72. Outer hinge seats 73 are fixedly connected to both sides of the injection mounting base 71. An inner hinge seat 731 is fixedly connected to the outer surface of the movable injection head 72. An inner hinge arm 74 is hinged to the outer surface of the outer hinge seat 73. An outer hinge arm 741 is hinged to the outer surface of the inner hinge seat 731. A conical shell 75 is fixedly connected to the outer surface of the outer hinge arm 741. A spiral cutting edge 751 is formed on the outer surface of the conical shell 75.

[0087] The inclined injection groove 721 is inclined outward, and the outer hinge arm 741 and the inner hinge arm 74 are symmetrically distributed, and the outer hinge arm 741 and the inner hinge arm 74 are hinged to each other.

[0088] With the injection protective sleeve 7 in place, during use, the injection mounting base 71 moves with the extension tube 52 and injects liquid bacteria through the movable injection head 72. The inclined injection groove 721 of the movable injection head 72 is opened in the radial position on the side. When it does not reach the injection area, the inclined injection groove 721 is inside the injection mounting base 71 and cannot inject outward. At this time, the conical shell 75 is closed. When the extension tube 52 rotates, it will drive the conical shell 75 to rotate and enter through the spiral cutting edge 751 on the surface. This converts the original static friction into rotational friction to reduce the resistance when moving forward. The rotational cutting forms a smooth channel, which reduces the backflow of the bacterial liquid.

[0089] When the input control slot 6 stops inputting liquid bacteria, it indicates that the extension collar 521 is blocked by the travel limit seat 421. At this time, the extension tube 52 and the injection mounting seat 71 cannot continue to move, but the movable injection head 72 can continue to move a distance inside the injection mounting seat 71, extending out from inside the injection mounting seat 71 to expose the oblique injection groove 721. At the same time, the inner hinge arm 74 and the outer hinge arm 741 push the conical outer shell 75 to both sides, so that the internal liquid bacteria are output from the oblique direction for injection.

[0090] In this embodiment, as Figure 1 , Figure 2 As shown, each component is installed inside the inoculation shell 1;

[0091] In this embodiment, as Figure 3 , Figure 4 As shown, the internal structure consists of a segmented drive shaft 2, an adjustable piston arm 3, a spacing adjustment arm 4, an extension injection tube 5, an input control groove 6, and an injection protective sleeve 7.

[0092] In this embodiment, as Figure 5 , Figure 6As shown, the input shaft 22 of the segmented drive shaft 2 rotates at a constant speed, and the tilting column 241 can adjust the swing amplitude by adjusting the angle, so that the adjustable piston arm 3 has different reciprocating strokes.

[0093] In this embodiment, as Figure 7 As shown, the extension column 231 can adapt to different spacings after the inclined column 241 is rotated;

[0094] In this embodiment, as Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the spacing adjustment arm 4 has only two states through the limiting rotating arm 43 and the tension spring 44;

[0095] In this embodiment, as Figure 12 , Figure 13 , Figure 14 As shown, the extended injection tube 5 is used in conjunction with the stroke limit seat 421 to trigger the opening and closing of the input control slot 6;

[0096] In this embodiment, as Figure 15 , Figure 16 , Figure 19 As shown, depending on the direction of movement of the driven lever 53, it may clamp and drive the extension tube 52 out, or it may loosen and not contact the extension tube 52.

[0097] In this embodiment, as Figure 17 As shown, the spacing of the tilting connecting arms 42 simultaneously controls the angle of the tilting column 241 and the distance from the travel limit seat 421 to the extension tube 52.

[0098] In this embodiment, as Figure 20 , Figure 21 As shown, the inner sliding tube 64 slides inside the input housing 63, causing different one-way valves 651 on both sides to be alternately exposed from the interaction groove 632 to control the extraction of liquid bacteria.

[0099] In this embodiment, as Figure 22 As shown, the injection protective sleeve 7 is installed at one end of the extension tube 52 and moves with the rotation;

[0100] In this embodiment, as Figure 23 , Figure 24 , Figure 25 As shown, the conical outer shell 75 opens as the movable injection head 72 extends.

[0101] The invention relates to the following: an edible fungus inoculation device and its usage method, the working process of which is as follows:

[0102] like Figures 1 to 25As shown, during use, the drive motor 21 drives the input shaft 22 to rotate at a constant speed. The rotation is transmitted to the output shaft 25 at the same speed and in the same direction through the symmetrically arranged extended hinge seats 23, inclined plates 24, and inclined columns 241. At the same time, the inclined column 241 swings with the inclined plates 24. The swing amplitude is determined by the axial distance between the two extended hinge seats 23. The inclined column 241 drives the piston head 331 to reciprocate linearly within the extraction sleeve 34 through the piston connecting arm 31, rotating mounting seat 32, and piston hinge arm 33, forming a variable stroke quantitative extraction. The stroke size is positively correlated with the tilt angle of the inclined column 241, realizing the quantitative intake of the liquid bacteria storage cylinder 11 into the fixed input groove 251 through the one-way input valve 35.

[0103] The connecting ring 41 moves axially synchronously with the extended hinge seat 23; the inclined connecting arms 42 on both sides are tightened by the tension spring 44, and form a bistable mechanism with the limiting rotating arm 43, the arm connecting shaft 432 and the pull-down switching plate 45; when the pull-down switching plate 45 is pressed, the limiting rotating arm 43 instantly flips from the horizontal collinear state to the bottom of the shaft limiting groove 451, and the spacing of the inclined connecting arms 42 switches between two levels, thereby synchronously changing the tilt angle of the inclined column 241, the stroke of the piston head 331 and the single extraction volume, realizing the rapid selection of "large" and "small" dose levels.

[0104] When the piston head 331 reciprocates, the driven pull rod 53 synchronously pushes and pulls the connecting slider 54; the inclined path groove 541 drives the side gripper 55 to radially clamp or loosen through the driven connecting column 542; the fixed tube 51 rotates in place with the output shaft 25 via the driven rotating shaft 511; when the side gripper 55 clamps the extension tube 52, it pushes it out in one direction, and releases it during the return stroke, so that the extension tube 52 maintains its extension length unchanged, realizing the deep hole propulsion of "rotation plus intermittent extension", and the needle roller 551 ensures that the rotation and axial movement do not interfere with each other;

[0105] When the extension collar 521 is limited by the travel limit seat 421, the angle between the movable hinge arm 611 and the fixed hinge arm 61 decreases, and the lifting column 62 lifts the inner sliding tube 64 along the transverse slide groove 621. After the inner sliding tube 64 is lifted, the original input side one-way valve 651 disengages from the interaction groove 632 and stops aspiration, while the other side one-way valve 651 opens, and the buffer bacterial solution in the extraction sleeve 34 is completely switched to the injection state, realizing the automatic switching of "aspiration-injection". After the extension tube 52 stops advancing, the movable injection head 72 continues to move forward relative to the injection mounting seat 71, and the inclined injection groove 721 is exposed. At the same time, the inner hinge arm 74 and the outer hinge arm 741 open the conical shell 75, and the bacterial solution is injected laterally along the inclined injection groove 721 into the smooth channel pre-cut by the spiral cutting edge 751, completing the sealing, directional, and quantitative inoculation.

[0106] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

The symmetrically arranged extended hinge seat (23), inclined plate (24), and inclined column (241) transmit the same speed and direction of rotation to the output shaft (25). At the same time, the inclined column (241) swings with the inclined plate (24). The swing amplitude is determined by the axial distance between the two extended hinge seats (23).

S2.
