[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] As attached Figure 1 To be continued Figure 7 As shown:

[0028] Example 1: This utility model provides an automatic solid inoculum inoculation machine, including a housing 1, a substrate cylinder 2 for placing inoculum inside the housing 1, a rotating disk 3 rotatably connected inside the substrate cylinder 2, a detachably connected knife holder 4 on the rotating disk 3, a knife disc 5 on the knife holder 4, and a hollow feeding rod 6 on the outer wall of the housing 1. The feeding rod 6 communicates with the inside of the substrate cylinder 2, and a pushing rod 7 is provided inside the feeding rod 6.

[0029] It also includes a control box 8, which is located inside the housing 1 and connected to the rear side of the substrate cylinder 2. The control box 8 is equipped with a power component, which drives the rotating disk 3 to rotate and push the solid substrate into the feed rod 6, where it is pushed out by the push rod 7.

[0030] It should be noted that the housing 1 contains a substrate cylinder 2 for holding solid bacteria. The rotating disc 3 can rotate inside the substrate cylinder 2. The blade holder 4 is mounted on the rotating disc 3. The housing 1 also has a feed rod 6. The power unit can drive the rotating disc 3 to rotate and drive the push rod 7 to move back and forth. The counterclockwise rotation of the blade holder 4 can break up the solid bacteria through the blade disc 5 and push them into the feed rod 6. After the blade disc 5 rotates past the position where the feed rod 6 connects with the substrate cylinder 2, the push rod 7 moves forward, thereby pushing out the solid bacteria in the feed rod 6. Thus, as the blade disc 5 rotates continuously, the push rod 7 moves back and forth intermittently to push out the solid bacteria in the feed rod 6, realizing automated solid bacteria inoculation, which improves the efficiency of inoculation compared to manual methods.

[0031] Specifically, the cutter head 5 is set in one on the cutter holder 4. The vertical cross-sectional profile of the cutter head 5 is "L" shaped. The initial position of the push rod 7 is set so that when it is fully retracted, its front end face is located behind the inlet of the feed rod 6. The size of the linkage 30 is set so that when one cutting edge of the cutter head 5 rotates through the inlet of the feed rod 6 and completes the pushing action, the push rod 7 just begins to move forward to push.

[0032] The substrate container 2 and the control box 8 are connected as a whole. The substrate container 2 is detached and connected to the inside of the housing 1 by means of screws. The substrate container 2 and the housing 1 are designed to be detachable. When inoculating oyster mushrooms, button mushrooms, nameko mushrooms and other fungi that are not easy to be infected, since there is no need to use air purifier 32 and sterilizing lamp 22, the substrate container 2 and the control box 8 can be taken out from the housing 1 and inoculated separately in the external environment.

[0033] When inoculating easily infected fungi such as morel mushrooms and wood ear mushrooms, air purification and sterilization are required. The substrate container 2 and the control box 8 can be installed inside the housing 1 to prevent contamination of the fungi. Adjustments can be made according to different fungi, which improves the flexibility of the device.

[0034] In this embodiment, the bottom of the housing 1 is provided with a support frame 9, and the bottom of the support frame 9 is provided with casters 10 near the four corners. The front face of the housing 1 is symmetrically provided with vertically distributed mounting plates 11. The two mounting plates 11 are provided with positioning holes 12 that are opposite to each other and distributed in multiple layers. The mounting plates 11 and the housing 1 are provided with a transparent glass 13 that is movably connected.

[0035] It should be noted that the housing 1 can be placed on the support frame 9 and casters 10, which facilitates the movement of the inoculation machine. The transparent glass 13 can be lowered when not inoculating, thus preventing the inoculum from being contaminated.

[0036] In this embodiment, a positioning plate 14 is provided at the bottom of the front end face of the transparent glass 13, and positioning blocks 15 are provided on both sides of the top of the positioning plate 14. An insert plate 16 is provided on the positioning block 15 and is movably connected. The insert plate 16 passes through the positioning block 15 and is inserted into the positioning card hole 12.

[0037] It should be noted that the positioning plate 14 is fixedly connected to the transparent glass 13, and the positioning block 15 is fixed on the top of the positioning plate 14. The set insert plate 16 can be inserted into the positioning card hole 12 at different heights, so that the transparent glass 13 can be adjusted to different heights, which does not affect the staff to receive bacteria and further avoids the bacteria from being infected.

[0038] In this embodiment, the cross-sectional profile of the substrate cylinder 2 is annular, the bottom of the knife holder 4 is provided with a positioning shaft 17, the positioning shaft is inserted into the hole opened at the top of the rotating disk 3, the top of the rotating disk 3 is provided with a limiting protrusion 18 near the edge, and the outer edge of the knife holder 4 is provided with an inward mating groove 19. The knife holder 4 rotates so that the limiting protrusion 18 is engaged in the mating groove 19.

[0039] It should be noted that by designing the knife holder 4 to be detachable, when the mating groove 19 on the knife holder 4 is rotated to engage with the limiting protrusion 18, the positioning shaft 17 at the bottom of the knife holder 4 is also inserted into the hole at the top of the rotating disk 3. Thus, when the rotating disk 3 rotates, it can drive the knife holder 4 to move together, so that the knife disk 5 pushes the bacteria into the feed rod 6. It also facilitates the subsequent cleaning of the knife holder 4, making it convenient and quick.

[0040] In this embodiment, the top of the substrate cylinder 2 is provided with a detachable extension cylinder 20, which is fastened to the top of the substrate cylinder 2. The back plate of the housing 1 is provided with an externally powered lighting lamp 21 and a sterilizing lamp 22.

[0041] It should be noted that by setting an extension tube 20 at the top of the substrate cylinder 2, which is attached to the top of the substrate cylinder 2, more microbial inoculum can be stored. The lighting lamp 21 makes it easy to observe the remaining amount of microbial inoculum in the substrate cylinder 2 and provides lighting environment. The sterilizing lamp 22 can sterilize the internal environment of the shell 1, further preventing the microbial inoculum from being contaminated.

[0042] In this embodiment, the power assembly includes a first pulley 23, a second pulley 24, a transmission belt 25, a rotating shaft 26, a motor 27, a micro switch 28, a trigger 29, and a linkage 30. The rotating shaft 26 is connected to the second pulley 24 and the first pulley 23. The transmission belt 25 is connected to the first pulley 23 and the second pulley 24. The motor 27 is mounted on the inner bottom plate of the control box 8. The output shaft of the motor 27 is connected to the rotating shaft 26 on the second pulley 24 via a coupling. The rotating shaft 26 on the first pulley 23 is connected to the bottom of the rotating disk 3. The micro switch 28 is mounted on the motor 27 and electrically connected to it.

[0043] It should be noted that, through the power components, the motor 27 starts and drives the pulley 24 to rotate via the rotating shaft 26. The pulley 24 is connected to the transmission belt 25 and can drive the pulley 23 to rotate, thereby driving the rotating shaft 26 on the pulley 23 to drive the rotating disk 3 to move. Finally, the knife holder 4 drives the knife disc 5 to rotate and push the inoculum into the feed rod 6, thus realizing automated inoculation.

[0044] In this embodiment, the trigger 29 cooperates with the micro switch 28. The trigger 29 includes a push rod 2901, a connecting plate 2902 and a return spring 2903. The push rod 2901 and the feed rod 6 are arranged in parallel and one end enters the control box 8. The connecting plate 2902 is fixed on the outer wall of the feed rod 6 and is movably connected to the push rod 2901. The return spring 2903 is sleeved on the push rod 2901 and abuts against the connecting plate 2902.

[0045] It should be noted that, through the set trigger 29, when it is necessary to inoculate bacteria, a force is applied to the push rod 2901, so that the end of the push rod 7 gradually moves towards the micro switch 28. When it touches the switch on the micro switch 28, the micro switch 28 is triggered. The micro switch 28 is electrically connected to the motor 27, thereby driving the motor 27 to work. When the push rod 2901 is released, under the rebound force of the return spring 2903, the push rod 2901 moves outward. When it is no longer in contact with the micro switch 28, the motor 27 stops working.

[0046] In this embodiment, the linkage 30 includes a linkage shaft 301, a connecting rod 302, and a bearing 303. The linkage shaft 301 is vertically connected to the bottom of the second pulley 24 and the tail end of the push rod 7. The linkage shaft 301 is eccentrically designed on the second pulley 24. The two linkage shafts 301 are movably connected to the two ends of the connecting rod 302 through the bearings 303 respectively.

[0047] It should be noted that, through the linkage component 30, there are two linkage shafts 301. One linkage shaft 301 is designed eccentrically on the pulley 24. The two ends of the connecting rod 302 are connected to the linkage shaft 301 through bearings 303 respectively. The other linkage shaft is movably connected to the other end of the push rod 7. Thus, as the pulley 24 rotates continuously, it will drive the connecting rod 302 to reciprocate, and finally make the push rod 7 move back and forth, continuously pushing out the inoculum material.

[0048] In this embodiment, the top plate of the housing 1 is provided with a fan 31 connected to an external power source, the top of the inside of the housing 1 is provided with an air purifier 32 that cooperates with the fan 31, and the side wall of the housing 1 is provided with a control switch 33.

[0049] It should be noted that the fan 31 is connected to the air purifier inside the housing 1, so that the external air is drawn in and filtered by the air purifier 32 before entering the housing 1 and being filtered to maintain a sterile environment during the inoculation process, thereby ensuring the survival of the bacteria.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
