Technical Field

[0001] The invention relates to the technical field of edible fungus production, in particular to an edible fungus inoculator. Background Art

[0002] Edible fungi refer to fungal foods that can be eaten by humans. There are many types of them, including shiitake mushrooms, oyster mushrooms, enoki mushrooms, king oyster mushrooms, etc. Edible fungi are usually rich in nutritional value, rich in protein, vitamins and minerals, and are considered a healthy food choice. Inoculation of edible fungi refers to adding fungi to the substrate during the cultivation of edible fungi to promote the growth, reproduction and formation of mycelium. It is one of the important measures to cultivate high-yield and high-quality edible fungi.

[0003] The patent publication number of the existing patent application is: CN209964823U, and the publication date is January 21, 2020. The name of the patent is "A liquid strain inoculator". The patent includes a frame, a conveyor belt arranged at the bottom of the frame, and a plurality of conveyor troughs for conveying bacteria bags are arranged at intervals on the conveyor belt. The upper part of the frame is provided with an inoculation mechanism and a control unit above the conveyor belt. The inoculation mechanism includes a plurality of quantitative syringes and inoculation needles connected thereto. The utility model uses a quantitative syringe to complete self-priming feeding and quantitative inoculation, which makes feeding simpler and more stable, and inoculation more accurate and efficient.

[0004] The above application has shortcomings. When inoculating, it is generally necessary to punch holes first and then inoculate. The step-by-step operation makes the process cumbersome, and the risk of contamination may be introduced during the switching process. Incomplete sterilization may lead to contamination. The punching rod and inoculation needle are easily contaminated with culture medium debris or external microorganisms during operation. When the inoculation needle is pulled out, the culture medium debris may be brought out and contaminate the inoculation hole. The cleaning of the inoculation needle depends on manual intervention. The needle needs to be cleaned manually after inoculation, and contamination may be caused by human negligence. Summary of the invention

[0005] The purpose of the present invention is to provide an edible fungus inoculator to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An edible fungus inoculator includes a frame and a sterilization chamber installed on the frame. It also includes a punching lifting frame and an inoculation lifting frame, which are sequentially installed in the sterilization chamber along the direction of the culture medium entering. A number of punching rods are installed at the bottom of the punching lifting frame. A positioning pressing plate is movably connected below the punching lifting frame inside the sterilization chamber. A number of inoculation needles corresponding to each punching rod are installed on the inoculation lifting frame. The bottom of the inoculation needle is rotatably connected to a needle head. A gas storage and purging mechanism is sleeved outside the punching rod. A transmission component for driving the needle head to rotate is installed on the inoculation lifting frame. The extraction path of the needle head is located in the exhaust area of the gas storage and purging mechanism. When the punching lifting frame descends, the inoculation lifting frame rises, squeezing the gas storage and purging mechanism to perform directional air curtain cleaning on the rotating needle head.

[0008] Preferably, a conveyor belt is installed inside the frame, and a plurality of brackets are equidistantly distributed on the outer wall of the conveyor belt. The center distance between adjacent brackets is equal to the center distance between the punching lifting frame and the inoculation lifting frame.

[0009] Preferably, positioning holes for the punching rods to pass through are formed on the positioning pressing plate. Elastic abutting blocks are connected to both sides of the inner wall of the positioning holes. Pulling rods are elastically connected to both sides of the inner wall of the sterilization chamber. The bottom ends of the pulling rods penetrate through the punching lifting frame and are fixed to the positioning pressing plate.

[0010] Preferably, the gas storage and purging mechanism includes an annular compression airbag sleeved outside the punching rod. The bottom of the annular compression airbag is connected to the positioning pressing plate, and the top is connected to the punching lifting frame. An exhaust pipe orifice is fixedly connected to one side of the annular compression airbag.

[0011] Preferably, a synchronous propulsion mechanism is installed at the top of the inoculation lifting frame. The bottom of the synchronous propulsion mechanism is inserted into each inoculation needle, and its end surface forms a volume chamber with the discharge port of the needle head.

[0012] Preferably, the synchronous propulsion mechanism includes a driving motor fixed to the top of the inoculation lifting frame. The output shaft of the driving motor is vertically and fixedly connected with a lead screw. A connecting rod is threadedly penetrated and installed on the lead screw. A number of push rods inserted into the inoculation needles are installed at the bottom of the connecting rod.

[0013] Preferably, an annular protective frame is rotatably sleeved outside the inoculation needle. The bottom of the annular protective frame is fixedly connected to the top end of the needle head, and the top of the annular protective frame is in transmission connection with the transmission component.

[0014] Preferably, the transmission assembly includes a movable rod slidably mounted on one side of the inoculation lifting frame. On both sides of the inner wall of the sterilization chamber, there are vertically and fixedly connected abutting racks respectively. The teeth on the two abutting racks are staggered from each other. Both ends of the movable rod are in abutting cooperation with the two abutting racks respectively. A transmission rack is fixedly connected to the bottom of the movable rod. A driven gear ring meshing with the transmission rack is sleeved on the top of the annular protective frame.

[0015] Preferably, a transmission shaft rod is rotatably connected in the sterilization chamber. Sector gears and transmission gears are fixedly connected to both ends of the transmission shaft rod. Transmission frames meshing with the sector gears are fixedly connected to both sides of the positioning pressing plate.

At the same time, the air storage and purging mechanism sleeved outside the punching rod is squeezed when the punching lifting frame descends, releasing a directional air flow to form an air curtain. The inoculation needle rotates through the transmission assembly, and the air curtain is used to blow the surface of the needle in all directions without dead angles, instantly removing residues during the process of pulling out the inoculation needle, avoiding debris from falling back or contaminating the inoculation holes, reducing the sterilization blind area.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figures 1-8, an edible fungus inoculator provided by an embodiment of the present invention includes a frame 1 and a sterilization chamber 2 installed on the frame 1, and further includes a punching lifting frame 3 and an inoculation lifting frame 4, which are sequentially installed in the sterilization chamber 2 along the direction of the culture medium entering. A plurality of punching rods 31 are installed at the bottom of the punching lifting frame 3. A positioning pressing plate 5 is movably connected inside the sterilization chamber 2 below the punching lifting frame 3. A plurality of inoculation needles 41 corresponding to each punching rod 31 are installed on the inoculation lifting frame 4. The bottom of the inoculation needle 41 is rotatably connected to a needle head 42. A gas storage and purging mechanism 6 is sleeved outside the punching rod 31. A transmission assembly 7 for driving the needle head 42 to rotate is installed on the inoculation lifting frame 4. The extraction path of the needle head 42 is located in the exhaust area of the gas storage and purging mechanism 6. When the punching lifting frame 3 descends, the inoculation lifting frame 4 is lifted to squeeze the gas storage and purging mechanism 6 to perform directional air curtain cleaning on the rotating needle head 42.

[0033] Specifically, the sterilization chamber 2 fixed on the frame 1 serves as the working area for punching and inoculating the culture medium. The punching lifting frame 3 and the inoculation lifting frame 4 are sequentially installed in the chamber along the culture medium conveying direction. A first electric push rod 84 connected to the sterilization chamber 2 is installed at the top of the punching lifting frame 3. A plurality of punching rods 31 are evenly installed at the bottom of the punching lifting frame 3. The gas storage and purging mechanism 6 outside it can surround the punching rods 31 to reduce the contact area between the punching rods 31 and the outside. Second electric push rods 84 connected to the sterilization chamber 2 are installed on both sides of the top of the inoculation lifting frame 4. Inoculation needles 41 corresponding one by one to the punching rods 31 are arranged on the inoculation lifting frame 4. The end of the inoculation needle 41 is connected by a bearing to a freely rotatable needle head 42, and the needle head 42 is connected to the transmission assembly 7. A movable positioning pressing plate 5 elastically connected below the punching station in the sterilization chamber 2 is used to fix and press the culture medium. The culture medium is conveyed into the sterilization chamber 2, and the positioning pressing plate 5 presses down to fix the culture medium. Then the punching lifting frame 3 drives a plurality of punching rods 31 to move down and pierce into the culture medium to complete punching. During the process of the punching lifting frame 3 descending, the positioning pressing plate 5 always presses the culture medium tightly. Since the gas storage and purging mechanism 6 is squeezed by the punching lifting frame 3, the gas stored inside it will be blown through the air outlet towards the needle head 42 of the inoculation needle 41 that is being pulled out after inoculation. After the inoculation of the next culture medium is completed, the inoculation lifting frame 4 is lifted, so that the needle head 42 is at a height where it can be blown by the airflow. The needle head 42 rotates at a high speed under the drive of the transmission assembly 7. When it is pulled out, its movement path passes through the air curtain area, and the rotating surface is purged in all directions by the airflow to remove residual debris and potential pollutants. The punching lifting frame 3 and the inoculation lifting frame 4 cooperate with each other. During the process of the punching lifting frame 3 moving down for punching, the inoculation lifting frame 4 is lifted. After punching is completed, the punching lifting frame 3 resets, and the positioning pressing plate 5 resets to release the culture medium. Then the inoculation lifting frame 4 moves down again to insert the inoculation needle 41 into the hole to inject the strain, and the equipment enters the next cycle.

[0034] Compared with the prior art, in the embodiment of the present invention, the punching lifting frame 3 and the inoculation lifting frame 4 are integrated in the same sterilization chamber 2, and the linkage lifting mechanism realizes the continuous operation of punching and inoculation, reduces the process switching time, improves the efficiency, and is completed entirely within the sterilization chamber 2 to avoid external contamination. At the same time, the air storage and purging mechanism 6 sleeved outside the punching rod 31 is squeezed when the punching lifting frame 3 descends, releasing a directional air flow to form an air curtain. The head of the inoculation needle 41 rotates through the transmission component 7, and in cooperation with the air curtain, the surface of the needle head 42 is purged comprehensively and without dead angles, immediately removing residues during the process of pulling out the inoculation needle 41, avoiding debris from falling back or contaminating the inoculation holes, reducing the sterilization blind area. The punching and inoculation lifting frames 4 move alternately, triggering air storage and purging by mechanical extrusion, without the need for an additional power source, simplifying the equipment structure, reducing energy consumption, and simultaneously realizing the automation synchronization of cleaning and operation.

[0035] In a further technical solution of the present invention, a conveyor belt 11 is installed inside the frame 1. A plurality of brackets 12 are equidistantly distributed on the outer wall of the conveyor belt 11. The brackets 12 are in a V shape, and the center distance between adjacent brackets 12 is equal to the center distance between the punching lifting frame 3 and the inoculation lifting frame 4. Specifically, the conveyor belt 11 realizes the precise intermittent conveying of the culture medium bags through the equidistantly distributed brackets 12. When the bracket 12 carries the culture medium into the sterilization chamber 2, its center distance matches the spacing between the punching lifting frame 3 and the inoculation lifting frame 4, ensuring that each culture medium bag undergoes the punching and inoculation processes in sequence. The stepping movement of the conveyor belt 11 is strictly synchronized with the actions of the punching lifting frame 3 and the inoculation lifting frame 4. When punching, the conveyor belt 11 is locked, and after inoculation is completed, the conveyor belt 11 automatically steps to the next working position. This design integrates loading, unloading, punching, and inoculation into a fully automatic production line. By matching the equidistant layout of the brackets 12 with the center distance of the equipment, the manual intervention error is eliminated, and continuous and efficient production is achieved.

[0036] In a further technical solution of the present invention, a positioning hole 51 for the punching rod 31 to pass through is provided on the positioning pressing plate 5. Elastic abutting blocks 53 are connected to both sides of the inner wall of the positioning hole 51. Elastic pull rods 21 are connected to both sides of the inner wall of the sterilization chamber 2. The bottom ends of the pull rods 21 penetrate through the punching lifting frame 3 and are fixed to the positioning pressing plate 5. Specifically, a top spring 23 is installed between the top of the pull rod 21 and the sterilization chamber 2. When the punching lifting frame 3 does not descend, the positioning pressing plate 5 is pulled upward by the pull rod 21 so as not to contact the culture medium, facilitating the culture medium after punching to enter the next process. When the punching lifting frame 3 descends and the punching needle passes through the positioning hole 51, the punching needle will first contact the abutting block 53, and the positioning pressing plate 5 is first pressed against the culture medium through the friction between the punching needle and the abutting block 53. After the position of the positioning pressing plate 5 is fixed, the punching needle pushes open the abutting block 53 and inserts into the culture medium. Through the guiding and constraining of the positioning hole 51, the punching position accuracy is guaranteed, and the damage to the culture medium caused by equipment vibration is reduced.

[0037] In a further technical solution of the present invention, the gas storage purge mechanism 6 includes an annular compressed air bag 61 sleeved on the outside of the punching rod 31, the bottom of the annular compressed air bag 61 is connected to the positioning pressure plate 5, and the top is connected to the punching lifting frame 3. One side of the annular compressed air bag 61 is fixedly connected with an exhaust pipe port 62. Specifically, the air bag is made of pressure-resistant silicone material, the bottom is fixed to the positioning pressure plate 5 by a buckle, and the top is sealed and connected to the punching lifting frame 3 by a flange. The inner side of the annular compressed air bag 61 is close to the outer wall of the punching rod 31, and the exhaust pipe port 62 is fixedly connected to the one side of the annular compressed air bag 61. The pipe mouth 62 is arranged on the outside of the annular compression airbag 61. When the positioning pressure plate 5 presses the culture medium, the perforated lifting frame 3 descends to squeeze the annular compression airbag 61 so that the sterile gas pre-stored therein is ejected at high speed from the exhaust pipe mouth 62, thereby realizing the on-demand triggering of the air curtain without the need for an additional air pump. The direction of the air curtain matches the movement trajectory of the needle 42 to maximize the cleaning efficiency. After the perforated lifting frame 3 is reset, the airbag returns to its original state under the action of elasticity, and the filtered sterile air is automatically replenished through the one-way air valve on the airbag.

[0038] In a further technical solution of the present invention, a synchronous propulsion mechanism 8 is installed on the top of the inoculation lifting frame 4, and the bottom of the synchronous propulsion mechanism 8 is inserted into each inoculation needle 41, and its end face and the discharge port of the needle 42 form a volume cavity. Specifically, when the inoculation lifting frame 4 carries each inoculation needle 41 and is inserted into the hole punched on the culture medium, the synchronous propulsion mechanism 8 simultaneously compresses the bacteria in each inoculation needle 41, forcing the bacteria to be evenly discharged from the needle 42 into the inoculation hole, without the need for separate injection and inoculation of each inoculation hole, thereby achieving high-precision quantitative inoculation.

[0039] In a further technical solution of the present invention, the synchronous propulsion mechanism 8 includes a driving motor 81 fixed to the top of the inoculation lifting frame 4, and the output shaft of the driving motor 81 is vertically fixedly connected with a screw rod 82, and a connecting rod 83 is installed on the screw rod 82 through a thread, and a plurality of push rods 84 inserted into the inoculation needle 41 are installed at the bottom of the connecting rod 83. Specifically, when the inoculation lifting frame 4 moves up and down, it can lift and lower with the synchronous propulsion mechanism 8. When the driving motor 81 is started, the screw rod 82 rotates and converts the rotational motion into the vertical lifting motion of the connecting rod 83 through threaded cooperation, so that the multiple push rods 84 at the bottom of the connecting rod 83 are pressed down linearly under the constraint of the syringe of the inoculation needle 41, compressing the bacteria inside, so that the bacteria are accurately discharged from the discharge port of the needle head 42 into the inoculation hole of the culture medium, ensuring that the inoculation amount of each hole is consistent, combined with the rotation of the needle head 42 and the air curtain cleaning, the full process automation of "pressing down-inoculation-cleaning-resetting" is realized, and the waste of bacteria and cross-contamination are completely eliminated.

[0040] In a further technical solution of the present invention, an annular protective frame 44 is rotatably sleeved on the outside of the inoculation needle 41, the bottom of the annular protective frame 44 is fixedly connected to the top of the needle 42, and the top of the annular protective frame 44 is transmission-connected to the transmission assembly 7. Specifically, after the inoculation is completed, during the upward movement of the inoculation lifting frame 4, the transmission assembly 7 can drive the needle 42 to rotate and be pulled out synchronously with the annular protective frame 44 by driving the annular protective frame 44, and the airflow sprayed by the air storage purge mechanism 6 is guided to the surface of the needle 42 in a rotating state, so as to achieve comprehensive cleaning of the needle 42, and the continuous rotation of the annular protective frame 44 and the needle 42 also causes the contaminants to be thrown away from the needle 42 by the centrifugal force, and double cleaning is achieved in combination with the air curtain. This design dynamically isolates the pollution source throughout the inoculation process by rotating the annular protective frame 44, and strengthens the airflow effect during the cleaning stage, so as to completely eliminate the cleaning blind spots of the traditional fixed protective structure.

[0041] In a further technical solution of the present invention, the transmission assembly 7 includes a movable rod 71 slidably mounted on one side of the inoculation lifting frame 4, and the inner walls of the sterilization chamber 2 are respectively vertically fixedly connected with abutment racks 22, and the teeth on the two abutment racks 22 are staggered. The two ends of the movable rod 71 are respectively abutted and matched with the two abutment racks 22, and the bottom of the movable rod 71 is fixedly connected with a transmission rack 72, and the top of the annular protective frame 44 is sleeved with a driven gear ring 45 meshing with the transmission rack 72. Specifically, when the inoculation lifting frame 4 is pressed down, the movable rod 71 moves downward accordingly, and its two ends slide along the inclined surfaces of the staggered abutment racks 22 on both sides. Affected by the rack staggered design, the movable rod 71 is produced during the descent process. The horizontal reciprocating swing drives the transmission rack 72 at the bottom to move left and right, and the transmission rack 72 meshes with the driven gear ring 45, converting the linear motion into continuous reciprocating rotation of the driven gear ring 45 and the annular protective frame 44. When the inoculation lifting frame 4 rises and resets, the movable rod 71 moves back and forth in the opposite direction, driving the annular protective frame 44 to reciprocate again. The rotation of the annular protective frame 44 is automatically triggered by the lifting action of the inoculation lifting frame 4, without the need for an independent motor drive, and the staggered layout of the rack eliminates the transmission dead point and ensures the rotation continuity. The continuous rotation of the annular protective frame 44 forms a dynamic isolation barrier throughout the inoculation process, allowing the rotating needle 42 combined with the air curtain cleaning to further reduce the risk of contamination.

[0042] In a further technical solution of the present invention, a transmission shaft rod 9 is rotatably connected in the sterilization chamber 2. Sector gears 91 and transmission gears 92 are fixedly connected to both ends of the transmission shaft rod 9. Transmission frames 52 meshing with the sector gears 91 are fixedly connected to both sides of the positioning pressing plate 5. An adjusting rack 46 meshing with the transmission gear 92 is vertically fixedly connected to the inoculation lifting frame 4. Specifically, when the punching and lifting frame 3 presses down, the teeth on the transmission frame 52 push the sector gear 91 to rotate counterclockwise, and the transmission shaft rod 9 rotates synchronously. The inoculation lifting frame 4 is forced to lift through the meshing of the transmission gear 92 and the adjusting rack 46. When the punching and lifting frame 3 resets, the pull rod 21 rebounds to drive the positioning pressing plate 5 to rise. This design converts the linear motion of the positioning pressing plate 5 into the reverse synchronous motion of the inoculation lifting frame 4 through a single transmission shaft rod 9, realizing the mechanical forced linkage of the punching and inoculation processes, eliminating control delay, ensuring the precise matching of action timing sequences. When the punching and lifting frame 3 punches the previous culture medium, the inoculation lifting frame 4 must complete the inoculation action and gradually rise, thereby ensuring the cleaning and sterilization effect of the needle 42 during continuous operation.

[0043] In a further technical solution of the present invention, a strain storage box 10 is installed in the sterilization chamber 2. Delivery hoses 101 are installed between the strain storage box 10 and each inoculation needle 41. One-way valves 102 are installed between the delivery hoses 101 and the inoculation needles 41. Specifically, the strain storage box 10 continuously supplies materials to each inoculation needle 41 through multiple independent delivery hoses 101. When the inoculation lifting frame 4 rises and resets, the piston push rod 84 / retracts to generate negative pressure in the volume chamber, and the spring-type one-way valve 102 opens. The strain is inhaled into the chamber through the hose under the push of the slightly positive pressure in the storage box. During inoculation, the push rod 84 presses down to compress the volume chamber, and the one-way valve 102 automatically closes. The strain is precisely injected into the punched culture medium from the needle 42. The strain only flows in the closed pipeline throughout the process, avoiding exposure to the environment of the sterilization chamber 2. Combining the air curtain cleaning and the rotation of the protective frame, zero pollution of strain delivery is achieved. The flexible delivery hose 101 bends freely with the lifting of the inoculation needle 41 to ensure the continuity of continuous operation.

[0044] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
