Description

Technical Field

[0001] This utility model relates to the field of silver ear fungus production technology, and in particular to a silver ear fungus liquid spawn inoculation machine. Background Technology

[0002] Cultivating Tremella in culture bottles allows for the reuse of these bottles, and their relatively regular shape facilitates automated production. As a result, Tremella cultivation in culture bottles has gradually replaced the traditional bag cultivation method.

[0003] Compared to solid spores of Tremella fuciformis, liquid spores have advantages such as good fluidity, easy dispersion, rapid germination, and numerous mycelial growth points. This effectively solves the problems of slow germination and easy contamination during inoculation, shortening the cultivation time and facilitating industrial production. Furthermore, liquid spores are not graded and can be used as mother cultures for primary culture production or directly as cultivation stock for production.

[0004] In the current production process of cultivating Tremella fuciformis in culture bottles, only the transportation of culture bottles can be automated. Manual intervention is still required when inoculating liquid spawn. This requires a large number of workers, resulting in high labor costs, high labor intensity, low efficiency, and a greater chance of contamination with more workers, which is not conducive to complete sterility in the production process. Utility Model Content

[0029] like Figures 1-6As shown, a liquid cultivar inoculation machine for Tremella fuciformis includes a conveying device 100 for conveying a tray containing culture bottles. The conveying device 100 is provided with an inoculation mechanism 200, an inoculation trough forming mechanism 300, and a lid opening and closing mechanism 400 arranged sequentially from front to back. The inoculation mechanism 200 includes an inoculation plate frame 210 located above the conveying device and which can be raised and lowered. The inoculation plate frame is provided with inoculation tubes 220 that correspond one-to-one with the culture bottles 510 on the tray 500. An inoculation control device for conveying liquid cultivar fuciformis to the inoculation tubes is provided above the inoculation plate frame 210. Culture bottles containing culture medium (with caps 520) are arranged in an array on a tray. A conveying device transports the tray forward to below the cap-opening / closing mechanism 400, where the caps of the culture bottles are removed. Then, the conveying device transports the tray backward to below the inoculation groove forming mechanism 300, where inoculation grooves are formed on the surface of the culture medium inside the culture bottles. Next, the conveying device transports the tray backward to below the inoculation mechanism 200, where the inoculation mechanism inoculates each culture bottle on the tray with liquid culture. After inoculation, the conveying device transports the tray forward again to below the cap-opening / closing mechanism 400, where the caps of the culture bottles are re-sealed, completing one inoculation operation. This novel liquid culture inoculation machine for Tremella fuciformis is convenient to use and highly practical. It achieves mechanized inoculation of liquid culture for Tremella fuciformis, not only improving production efficiency, reducing labor intensity, and saving manpower, but also improving inoculation quality, reducing the number of personnel entering the sterile room, and lowering the risk of contamination of the culture.

[0030] In this embodiment, the inoculation control device includes a control frame 230 fixedly connected above the inoculation plate rack. A dispensing cylinder 240 is horizontally arranged at the top of the control frame, and several dispensing ports are opened at the bottom of the dispensing cylinder. Each dispensing port is connected to an inoculation tube 220 via a dispensing hose 250. From top to bottom, the control frame is equipped with a first intercepting device, an inoculation volume control device, and a second intercepting device. The dispensing hose passes through the first intercepting device, the inoculation volume control device, and the second intercepting device in sequence. The liquid inoculum in the dispensing cylinder 240 flows into the inoculation tube through the dispensing hose, and the first intercepting device, the inoculation volume control device, and the second intercepting device control the dispensing and the dispensing volume.

[0031] In this embodiment, the first interception device includes a first fixed crossbar 231 and a first movable pressure bar 232 that cooperate to clamp the feed hose; the inoculation amount control device includes a fixed pressure plate 233 and a movable pressure plate 234 that cooperate to clamp the feed hose; the second interception device includes a second fixed crossbar 235 and a second movable pressure bar 236 that cooperate to clamp the feed hose. When the first movable pressure bar 232 moves toward the first fixed crossbar 231, the two cooperate to clamp the feed hose to achieve interception; when the second movable pressure bar 236 moves toward the second fixed crossbar 235, the two cooperate to clamp the feed hose to achieve interception; when the movable pressure plate 234 moves toward the fixed pressure plate 233, the two cooperate to clamp the feed hose, thereby squeezing the feed hose and forcing the liquid inoculum in the feed hose into the culture bottle. Specific operation process: (1) The first intercepting device clamps the upper part of the feeding hose to block the upper part of the feeding hose, and then the second intercepting device is released. At this time, the liquid bacteria in the feeding hose will not flow down; (2) The inoculation amount control device clamps the middle part of the feeding hose and squeezes the middle part of the feeding hose to squeeze the predetermined amount of liquid bacteria into the culture bottle; (3) The second intercepting device clamps the lower part of the feeding hose to block the lower part of the feeding hose, and then the first intercepting device and the inoculation amount control device are released. The liquid bacteria in the mixing cylinder continues to fill the feeding hose, and the inoculation operation is completed. By changing the movable pressure plate 234 of different widths, the length of the middle part of the feeding hose squeezed by the inoculation amount control device can be changed, thereby adjusting the amount of liquid bacteria (i.e., the inoculation amount). This inoculation control device can simultaneously control all feeding tubes to move synchronously.

[0032] In this embodiment, the culture flasks on the tray are arranged in a 4*4 array, and two sets of inoculation control devices are set above the inoculation plate rack 210. Each set of inoculation control devices is connected to 8 inoculation tubes for inoculating 8 culture flasks.

[0033] In this embodiment, the inoculation plate frame is driven to rise and fall by the first lifting cylinders 260 on both sides of the conveying device; the first movable pressure rod is driven by cylinder A located behind the first fixed crossbar, and the telescopic rod of cylinder A passes through the first fixed crossbar and connects to the first movable pressure rod; the movable pressure plate is driven by cylinder B located behind the fixed pressure plate, and the telescopic rod of cylinder B passes through the fixed pressure plate and connects to the movable pressure plate; the second movable pressure rod is driven by cylinder C located behind the second fixed crossbar, and the telescopic rod of cylinder C passes through the second fixed crossbar and connects to the second movable pressure rod.

[0034] In this embodiment, in order to remove air from the liquid bacterial culture, an air vent is provided at the top of the mixing cylinder, and a buffer container 270 is connected to the upper end of the air vent. The upper end of the buffer container is provided with an air outlet, which can be equipped with a valve.

[0035] In this embodiment, a storage tank 600 containing liquid tremella fuciformis culture is also included. The storage tank is provided with a discharge port, and a delivery pipe 610 is connected between the discharge port and the mixing cylinder. A high-pressure air pipe 620 is connected to the upper part of the storage tank, and a filter is connected in series on the high-pressure air pipe. The pressure of high-pressure air is used to squeeze the liquid tremella fuciformis culture in the storage tank into the mixing cylinder. The high-pressure air is filtered to avoid introducing impurities or bacteria. At the same time, compared with the pumping method, it can better protect the culture.

[0036] In this embodiment, the inoculation tank forming mechanism 300 includes a forming frame 310 fixed on the conveying device. The forming frame 310 is provided with a liftable forming plate frame 320. Rotatable forming rods 330, which correspond one-to-one with the culture bottles on the tray and extend downward, are arranged in an array on the forming plate frame. A forming punch 340 is fixedly connected to the lower end of the forming rod.

[0037] In this embodiment, the forming punch has a rotating structure. The middle part of the forming punch is cylindrical, and the lower part is an inverted cone shape with a larger upper part and a smaller lower part. The upper diameter of the inverted cone part is smaller than the lower diameter of the cylindrical part. The upper end of the inverted cone part and the lower end of the cylindrical part are connected by a conical surface. The lower end of the inverted cone part has an arc-shaped blunt head structure. The forming punch 340 forms a special-shaped inoculation groove, which is beneficial for quantitative inoculation of the strain and also for mycelial growth and development during the culture period.

[0038] In this embodiment, gear disks 350, each corresponding to a forming rod, are arrayed on the upper side of the forming plate frame. The gear disks are rotatably connected to the forming plate frame, and the upper ends of the forming rods pass through the forming plate frame and connect to the center of the corresponding gear disk. Adjacent gear disks mesh with each other. A drive motor (not shown in the figure) is provided on the forming plate frame. The drive motor is specifically located at... Figure 4 Above the gear disk at position A, and connected to the forming plate frame via a motor bracket, the main shaft of the drive motor is directly coaxially connected to the gear disk, and the main shaft of the drive motor is connected to one of the gear disks in a transmission connection.

[0039] In this embodiment, the molding frame is provided with a stabilizing shelf 360 located below the molding plate frame and capable of being raised and lowered. The molding rod passes through the stabilizing shelf and slides and rotates with the stabilizing shelf. A pair of second lifting cylinders 370 are provided on both sides above the molding frame to drive the molding plate frame to rise and fall. Several connecting rods are connected between the molding plate frame and the stabilizing shelf.

[0040] In this embodiment, the cap opening and closing mechanism 400 includes a cap opening lifting plate 410. A pair of vertical guide shafts for guiding the cap opening lifting plate 410 are fixedly connected to both sides of the conveying device. The upper ends of the four vertical guide shafts are connected together by a rectangular connecting plate. The cap opening lifting plate 410 is provided with four guide sleeves that slide in cooperation with the corresponding vertical guide shafts. A plurality of longitudinal partitions 420 are arranged laterally at intervals on the lower side of the cap opening lifting plate. A channel 430 is formed between adjacent longitudinal partitions for the culture bottle cap to pass through. The longitudinal partitions on both sides of the channel... The device is provided with a wing plate 421 extending to the lower side of the bottle cap. The distance between the wing plates on both sides of the channel is less than the diameter of the bottle cap so that the bottle cap can be lifted by the wing plate when the cap-opening lifting plate is raised. When the tray containing the culture bottles enters from the cap-opening lifting plate 410, the array of culture bottles corresponds to one channel 430 for each column. Raising the cap-opening lifting plate 410 can lift the bottle cap of the culture bottle by the wing plate 421. After the cap is opened, the culture bottle returns to the inoculation mechanism with the tray to complete the inoculation. After the inoculation is completed, the culture bottle moves with the tray to the cap-opening and closing mechanism 400 to complete the cap closing.

[0041] In this embodiment, the lifting plate 410 is driven to move up and down by a lifting mechanism. The lifting mechanism includes a transverse rotating shaft 450 located below the conveying device and driven to rotate by a fourth lifting cylinder 440. A first swing arm 451 is fixedly connected to the middle of the transverse rotating shaft. The first swing arm is hinged to one end of the fourth lifting cylinder, and the other end of the fourth lifting cylinder is hinged to the frame of the conveying device. Second swing arms 452 are fixedly connected to both ends of the transverse rotating shaft. A connecting rod 460 is connected between the second swing arm and the corresponding side of the lifting plate. The two ends of the connecting rod are respectively connected to the second swing arm and the side of the lifting plate. When the fourth lifting cylinder 440 extends or retracts, it drives the transverse rotating shaft to rotate through the first swing arm. Then, the transverse rotating shaft drives the second swing arm at the end to swing. The second swing arm drives the lifting plate 410 to move up and down through the connecting rod.

[0042] In this embodiment, a plurality of pressing cylinders 470 are provided above the cap lifting plate. The telescopic rod of the pressing cylinder faces downward and is connected to a transition plate 471. A capping plate 472 for pressing the bottle cap is provided below the transition plate. A spring 473 is connected between the capping plate and the transition plate. The pressing cylinder not only plays the role of closing the cap, but also pushes the capping plate to press the bottle cap before the longitudinal spacer lifts the bottle cap, so as to avoid the bottle cap moving when it is lifted and causing misalignment when closing the cap.

[0043] In this embodiment, the conveying device 100 is a roller conveyor, and the conveying device is provided with several lifting blocks 110 for blocking the trays. The lifting blocks are driven to rise and fall by a third lifting cylinder 120 located below them. A lifting block 110 for blocking the trays is provided below the front side of the inoculation mechanism. The lifting blocks restrict the position of the trays and prevent the trays from moving during the inoculation process. After inoculation is completed, the trays continue to move forward along the conveying device. A lifting block 110 is provided below the rear side of the opening and closing mechanism 400 to block the trays to complete the opening and closing operation. A lifting block 110 for blocking the trays is provided below the front side of the inoculation tank forming mechanism 300 to block the trays to complete the inoculation tank forming operation. A lifting block 110 is also provided in front of the inoculation mechanism to block the next tray. At the same time, several sensors for sensing the trays are also provided on the side of the conveying device to determine whether the trays containing culture bottles are in place.

[0044] The working process of the Tremella fuciformis solid spawn inoculation machine:

[0045] (1) The staff places the tray containing the culture bottles at the front end of the conveyor device, and the conveyor device moves in the forward direction;

[0046] (2) The tray passes under the inoculation mechanism and the inoculation tank forming mechanism and then reaches the bottom of the opening and closing mechanism (i.e., the bottom of the opening lifting plate). The caps of each row of culture bottles on the tray are located in the corresponding channel.

[0047] (3) The opening and closing mechanism lifts and opens the cap of the culture bottle. Specifically, the pressing cylinder extends to press the cap plate against the cap of the culture bottle. At this time, the spring is in a compressed state. Then, the fourth lifting cylinder drives the opening lifting plate to lift the cap through the wing plate of the longitudinal partition to separate it from the culture bottle.

[0048] (4) The conveying device moves in the opposite direction, so that the culture bottle after opening moves with the tray to the bottom of the inoculation tank forming mechanism;

[0049] (5) The second lifting cylinder extends, and the forming plate frame drives all the forming rods to descend to the specified height. The forming punch at the lower end of the forming rod forms an inoculation groove on the upper surface of the culture medium in the culture bottle. The second lifting cylinder retracts, and the forming plate frame drives all the forming rods to rise and reset.

[0050] (6) The conveying device moves in the opposite direction, so that the culture bottle that has completed the inoculation tank formation moves with the tray to the bottom of the inoculation mechanism;

[0051] (7) The inoculation mechanism injects a fixed amount of liquid bacterial culture into the inoculation tank inside the culture bottle through the inoculation tube;

[0052] (8) The conveying device moves in the forward direction. The culture bottles that have been inoculated return to the bottom of the opening and closing mechanism (i.e., the bottom of the opening and closing lifting plate) with the tray. The opening and closing mechanism puts the bottle cap back on the culture bottle. Specifically, the fourth lifting cylinder drives the opening and closing lifting plate to descend so that the bottle cap is put back on the culture bottle. Then the pressing cylinder contracts, and the transition plate lifts and resets the pressure plate through the spring.
