Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to a handheld tremella fuciformis spawn expansion machine. Background Technology

[0002] During the growth of white fungus, the inoculation opening is often too small to meet the subsequent growth needs, requiring the hole to be enlarged. In domestic production, this is typically done manually with a utility knife, resulting in inconsistent and unstable cut sizes and shapes. If the cut is too small, the desired enlargement is not achieved. If the cut is too large, the tremella spawn is easily contaminated, affecting yield and even causing spoilage. It may also lead to excessive contact area between the tremella and the substrate during maturity, increasing the difficulty and workload of removing the basal layer during harvesting. Therefore, the current method of manual hole enlargement negatively impacts the yield and quality of white fungus. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, this invention provides a handheld tremella fuciformis spawn expansion machine that ensures the shape and size of the incision formed during expansion are regular.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, the present invention provides a handheld tremella fuciformis spawn expansion machine, comprising a main frame, a gripping mechanism, a driving mechanism, a transmission mechanism, and multiple expansion mechanisms. The gripping mechanism, the driving mechanism, the transmission mechanism, and the multiple expansion mechanisms are all disposed on the main frame. The driving mechanism is connected to the transmission mechanism, and the transmission mechanism is respectively drivenly connected to the multiple expansion mechanisms.

[0006] The hole-expanding mechanism includes a hole-expanding bracket, a rotating assembly, a telescopic assembly, a blade holder mounting component, a blade mounting component, a waste film treatment assembly, and a blade. The telescopic assembly includes a first elastic element and a guide element. The hole-expanding bracket is fixed to the main frame. The rotating assembly is mounted on the hole-expanding bracket. The first end of the rotating assembly is connected to the transmission mechanism, and the second end of the rotating assembly is fixedly connected to the blade holder mounting component. The blade mounting component is slidably disposed on the blade holder mounting component. One end of the blade mounting component has a receiving groove, and the other end is connected to the blade. The first elastic element is located in the receiving groove and sleeved outside the guide element. The blade holder mounting component has a limiting plate in the rebound direction of the first elastic element. One end of the guide element is fixedly connected to the limiting plate. The driving mechanism drives the blade to rotate sequentially through the transmission mechanism and the rotating assembly. The blade is used to cut the membrane on the tremella fuciformis stick to form an incision.

[0007] The blade mounting component is also equipped with a rolling bearing near the blade, and the lowest point of the rolling bearing is higher than the lowest point of the blade when in operation.

[0008] The waste film treatment assembly includes a guide block and two inverted needle rods. The guide block is disposed inside the rotation axis of the rotating assembly. One end of each inverted needle rod is fixedly installed on the guide block. The two inverted needle rods are located within the rotation circle of the blade. The other end of each inverted needle rod is tapered and its lowest point is lower than the lowest point of the blade when in operation.

[0009] Optionally, the rotating assembly includes a rotating wheel, a limiting snap ring, a rotary bearing, a transition ring, and a rotating shaft. The rotating shaft is fitted with the rotating wheel, the limiting snap ring, the rotary bearing, and the transition ring sequentially from top to bottom on its outer side. The rotating wheel serves as the first end of the rotating assembly and is connected to the transmission mechanism. The rotary bearing is fixed to the bearing seat of the cavity expansion bracket. The end of the rotating shaft away from the rotating wheel serves as the second end of the rotating assembly and is fixedly connected to the tool holder mounting component.

[0010] The limiting retaining ring is disposed above the rotary bearing, and the transition ring is disposed below the rotary bearing and above the tool holder mounting component.

[0011] Optionally, the waste film treatment assembly further includes a limiting cap, a second elastic element, a waste film ejection rod, and a waste film ejection block. The waste film ejection rod is slidably installed in the guide block. The second elastic element is sleeved on the outer side of the extension of the waste film ejection rod above the waste film support in the cavity expansion bracket, and its end is connected to the limiting cap. The second elastic element is located between the limiting cap and the waste film support.

[0012] The waste film ejector rod is fixedly connected to the waste film ejector block at one end near the blade. The waste film ejector block is placed horizontally and its two horizontal ends are respectively sleeved on the two inverted needle rods. The limiting cap presses down to drive the waste film ejector rod to slide downward and compress the second elastic element. The waste film ejector rod drives the waste film ejector block to slide downward along the inverted needle rod.

[0013] Optionally, it also includes a positioning mechanism, which is disposed on the side of the main frame where the blade is located. The positioning mechanism includes a long side limiting plate, a short side limiting plate and an upper surface limiting plate. The lowest point of the upper surface limiting plate is higher than the lowest points of the long side limiting plate and the short side limiting plate when the working state is working.

[0014] The upper surface limiting plate starts from the outside of the first cavity expansion mechanism, and is set for each cavity expansion mechanism until the outside of the last cavity expansion mechanism. The long side limiting plate is set only on the outside of the left and right cavity expansion mechanisms respectively. The short side limiting plates are set in groups of two, and the two short side limiting plates in each group are located on the front and rear sides of the upper surface limiting plate between the two cavity expansion mechanisms.

[0015] Optionally, the gripping mechanism is provided with a set of handles on each of the adjacent sides of the main frame.

[0016] Optionally, the drive mechanism includes a motor and a reducer, and the transmission mechanism includes a synchronous pulley, a synchronous belt, an idler pulley, a transmission bearing, a tension pulley, and a transmission retainer. The reducer, the synchronous pulley, and the idler pulley are all fixed on the main frame. The tension pulley is fixed on the bearing seat of the cavity expansion bracket. The lower end face of the transmission bearing is sleeved on the outside of the tension pulley, and the transmission retainer is sleeved on the outside of the tension pulley and located on the upper end face of the transmission bearing.

[0017] The motor is connected to the synchronous pulley via a reducer. The idler pulley is located on one side of the plurality of cavity-expanding mechanisms and away from the cavity-expanding mechanisms. The tensioning pulley is located on the other side of the plurality of cavity-expanding mechanisms and at least one is located between two cavity-expanding mechanisms. The projection of the tensioning pulley along the arrangement direction of two adjacent cavity-expanding mechanisms is located on the projection of the cavity-expanding mechanism in the same direction.

[0018] The synchronous belt is sleeved on the synchronous pulley, and one end of it passes through the side of the idler pulley away from the cavity-expanding mechanism and then sleeves on the outermost cavity-expanding mechanism. It then passes sequentially through the side of the transmission bearing near the cavity-expanding mechanism, the side of the cavity-expanding mechanism away from the idler pulley, until it passes through the last cavity-expanding mechanism and returns to the synchronous pulley.

[0019] Optionally, the first elastic element is a spring.

[0020] In summary, the present invention has the following advantages over the prior art:

[0021] (1) The incision formed by the expansion of the cavity in this invention has a regular shape and stable size.

[0022] Existing artificial planting holes are roughly elliptical in shape, with varying hole lengths. Overly long holes not only cause excessive contact between the tremella and the substrate, leading to contamination and reduced yield, even rendering the tremella unusable, but also result in excessive ear-shaped growths during harvesting, increasing the workload of ear-shaped growth removal and reducing the effective weight of the tremella, thus decreasing farmer profits. Conversely, overly short holes cannot provide the necessary nutrients for tremella growth, resulting in low yields and reduced farmer profits. This invention addresses this by creating a regular and stable incision shape. By modifying the cutting dimensions of the planting mechanism, it is possible to create incisions suitable for healthy tremella production, improving the quality and stability of the tremella, ultimately benefiting farmers by increasing their profits and reducing costs, including planting hole costs and ear-shaped growth removal costs.

[0023] (2) This invention realizes handheld acupoint expansion.

[0024] Currently, most workers involved in expanding the planting holes are middle-aged or elderly women who are unable to perform heavy physical labor. This invention, however, is lightweight and compact, allowing for easy operation by a single person using both hands. During the expansion stage, the mushroom logs are stored in orderly intervals within layers of steel frames. Therefore, the logs can be expanded directly on the frames by hand, eliminating the need to manually remove the logs, expand the holes, and then put them back, thus reducing labor intensity and increasing efficiency. Because of limited working space, large continuous expansion mechanisms cannot be accommodated. This invention, through its simple structural design, easily achieves continuous expansion within confined working spaces.

[0025] (3) The present invention can stably, reliably and completely cut the upper surface of the mushroom stick.

[0026] The mushroom substrate is a solid object formed by an outer membrane enclosing the internal culture medium. During the rotating cutting process, the membrane at the cut portion becomes loose and warps, causing the blade to jam. Without the pressure of a rolling bearing, the blade would become stuck in the substrate, resulting in excessive resistance and preventing further cutting. Simultaneously, the rolling bearing also limits the cutting depth. Secondly, the surface of the mushroom substrate is a semi-circular arc surface, higher in the middle and lower on both sides. As the blade rotates from the lower to the higher part of the substrate surface, the rolling bearing smoothly climbs upwards along the semi-circular arc surface, and the spring in the retractable component automatically raises the blade along the upward movement of the rolling bearing. The combined action of the rolling bearing and the spring allows the blade to smoothly cut from the lower to the higher part of the substrate surface. If a rectangular limiting block were used instead of a rolling bearing, the limiting block and the blade would become stuck in the culture medium, preventing further cutting. Furthermore, the blade of this invention does not require sensor positioning to ensure it always cuts from the same starting point; it can cut at any point within its travel radius to achieve a complete cut.

[0027] (4) The present invention can complete the cavity expansion and mold taking in one go.

[0028] This invention places a conical inverted needle rod inside a hollow rotating shaft, and designs a suitable taper and barb on the conical inverted needle rod. In a narrow space, without the need for an electric power source, it can remove waste film while the machine is detaching from the tremella fuciformis stick, achieving the effect of expanding the hole and taking out the mold in one go.

[0043] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0044] Example 1

[0045] Please refer to Figures 1 to 7 A handheld tremella fuciformis spawn dilution machine includes a main frame 1, a gripping mechanism 2, a driving mechanism 3, a transmission mechanism 4, a positioning mechanism 6, and multiple dilution mechanisms 5. Since existing tremella fuciformis spawn typically requires three incisions, this embodiment uses three dilution mechanisms 5 to cut all the holes on a single tremella fuciformis spawn at once.

[0046] Reference Figure 1 and Figure 2 As can be seen, the main frame 1 in this embodiment is a plate-shaped body. The gripping mechanism 2, the driving mechanism 3, the transmission mechanism 4, the positioning mechanism 6, and the multiple cavity-expanding mechanisms 5 are all mounted on the main frame 1. The driving mechanism 3 is connected to the transmission mechanism 4, and the transmission mechanism 4 is respectively connected to the multiple cavity-expanding mechanisms 5 through transmission.

[0047] Reference Figure 1 and Figure 3 It can be seen that the holding mechanism 2 has a set of handles 21 on each of the adjacent sides of the main frame 1. Specifically, the handles 21 are installed on the handle mounting block by screws, and the handle mounting block is installed on the main frame 1 by screws. In this way, when in operation, the operator holds one of the handles 21 with each hand to expand the holes of the tremella fuciformis sticks.

[0048] Reference Figure 1 , Figure 3 , Figure 4 and Figure 7 It can be seen that the drive mechanism 3 includes a motor 31 and a reducer 32, and the transmission mechanism 4 includes a synchronous pulley 41, a synchronous belt 42, an idler pulley 43, a transmission bearing 45, a tensioner pulley 44, and a transmission retaining ring 46. The reducer 32, synchronous pulley 41, idler pulley 43, and tensioner pulley 44 are all fixed to the main frame 1. For example, the reducer 32 is mounted to a reducer mounting plate with screws, and the reducer mounting plate is mounted to the main frame 1 with screws. Similarly, the idler pulley 43 is placed on an idler pulley mounting plate, and the idler pulley mounting plate is mounted to the main frame 1 with screws. The idler pulley 43 also has a retaining ring for limiting its position. (Refer to...) Figure 3 and Figure 4 It can be seen that the tensioning wheel 44 is fixedly installed on the bearing seat 511 of the cavity expansion bracket 51 by screws. The lower end face of the transmission bearing 45 is sleeved on the outside of the tensioning wheel 44. The transmission retaining ring 46 is sleeved on the outside of the tensioning wheel 44 and located on the upper end face of the transmission bearing 45. The shoulder of the tensioning wheel 44 limits the lower end face of the transmission bearing 45, and the transmission retaining ring 46 limits the upper end face of the transmission bearing 45 to tension the synchronous belt 42.

[0049] Specifically, the motor 31 is connected to the synchronous pulley 41 through the reducer 32. The idler pulley 43 is located on one side of the multiple cavity expansion mechanisms 5 and away from the cavity expansion mechanism 5. The tensioning pulley 44 is located on the other side of the multiple cavity expansion mechanisms 5 and at least one is located between two cavity expansion mechanisms 5. The projection of the tensioning pulley 44 along the arrangement direction of two adjacent cavity expansion mechanisms 5 is located on the projection of the cavity expansion mechanism 5 in the same direction, so that the tensioning effect can be achieved.

[0050] In this embodiment, the synchronous belt 42 is fitted onto the synchronous pulley 41, and one end passes over the idler pulley 43 on the side away from the cavity-expanding mechanism 5 before being fitted onto the outermost cavity-expanding mechanism 5. It then sequentially passes over the transmission bearing 45 on the side near the cavity-expanding mechanism 5, and the cavity-expanding mechanism 5 on the side away from the idler pulley 43, until it passes the last cavity-expanding mechanism 5 and returns to the synchronous pulley 41. In this embodiment, as... Figure 3It can be seen that a tensioning wheel 44 is provided on both sides of each cavity expansion mechanism 5, so that two tensioning wheels 44 are provided in parallel between two adjacent cavity expansion mechanisms 5, and the synchronous wheel 41 is also arranged in parallel with the three cavity expansion mechanisms 5. At this time, one end of the synchronous belt 42 passes through the idler wheel 43 on the side away from the cavity expansion mechanism 5 and then is sleeved on the outermost cavity expansion mechanism 5. Then it passes through the two transmission bearings 45 on the side near the cavity expansion mechanism 5, the side of the middle cavity expansion mechanism 5 away from the idler wheel 43, then through the two transmission bearings 45 on the side near the cavity expansion mechanism 5, and the last cavity expansion mechanism 5 near the synchronous wheel 41, and then passes through one transmission bearing 45 and returns to the synchronous wheel 41. Due to the position of the tensioning wheel 44, when the synchronous wheel 41 rotates, the synchronous belt 42 will drive the rotating component 52 on the cavity expansion mechanism 5 to rotate.

[0051] Since handheld devices are required for three-hole aeration operations, existing commercially available drive devices cannot be directly used. A drive device design based on the overall structure is necessary. Furthermore, the high speed of the small DC motor, coupled with the need to simultaneously drive three aeration mechanisms 5, necessitates a key technical design for the transmission mechanism 4. Therefore, the design of the drive mechanism 3, transmission mechanism 4, and multiple aeration mechanisms 5 in this embodiment is an innovative design suitable for three-hole aeration of Tremella fuciformis logs. After the initial deceleration via the reducer 32, a second deceleration occurs via the synchronous pulley 41 and the rotating wheel 521 on the aeration mechanism 5. This achieves the effect of one motor 31 simultaneously driving multiple aeration mechanisms 5, and the design of the transmission mechanism 4 overcomes the problem of the high speed of the small DC motor.

[0052] like Figure 2 and Figure 5As shown, the positioning mechanism 6 is located on the side of the main frame 1 where the blade 53 is located. The positioning mechanism 6 includes a long side limiting plate 61, a short side limiting plate 62, and an upper surface limiting plate 63. When in operation, the lowest point of the upper surface limiting plate 63 is higher than the lowest points of the long side limiting plate 61 and the short side limiting plate 62 and is flush with the lowest point of the rolling bearing 562. The specific height is based on the size of the tremella fuciformis stick, and in this embodiment, it can be 40mm, 50mm, or 60mm, etc. The upper surface limiting plate 63 starts from the outside of the first expanding hole mechanism 5, and is set for each expanding hole mechanism 5 until the outside of the last expanding hole mechanism 5. The long side limiting plate 61 is only set on the outside of the left and right expanding hole mechanisms 5 respectively. The short side limiting plates 62 are in groups of two, and the two short side limiting plates 62 in each group are located on the front and rear sides of the upper surface limiting plate 63 between the two expanding hole mechanisms 5. Specifically, in this embodiment, the Tremella fuciformis stick has three holes corresponding to three expansion mechanisms 5. Therefore, four upper surface limiting plates 63 are provided. The two outermost upper surface limiting plates 63 are provided with long side limiting plates 61, and the two middle upper surface limiting plates 63 are provided with two short side limiting plates 62 on the front and back sides. In this way, the two long side limiting plates 61 limit the length direction of the Tremella fuciformis stick, and the four short side limiting plates 62 uniformly limit the width direction of the Tremella fuciformis stick. The upper surface limiting plates 63 limit the position of the blade mounting piece 56 on the upper surface of the Tremella fuciformis stick. Considering that the Tremella fuciformis stick is originally placed on a shelf and its lower surface is a fixed surface, it is equivalent to the lower surface of the Tremella fuciformis stick being fixed as well. Therefore, this embodiment uses the Tremella fuciformis stick to limit the position of six surfaces in total (up, down, left, right, front, and back) to ensure the stability of the Tremella fuciformis stick when it is cut.

[0053] Reference Figures 4 to 7 ,in, Figure 4 and Figure 5 A schematic diagram of the cavity expansion mechanism 5 is obtained from both top-down and bottom-up perspectives. Figure 6 Front view and Figure 7 The cross-sectional view serves as a comparison between the inside and outside, facilitating the understanding of the invention by those skilled in the art.

[0054] Specifically, such as Figure 7It is known that the cavity expansion mechanism 5 includes a cavity expansion bracket 51, a rotating component 52, a telescopic component 54, a blade holder mounting component 55, a blade mounting component 56, a blade 53, and a waste film treatment component 57. The cavity expansion bracket 51 is fixed on the main frame 1, the rotating component 52 is mounted on the cavity expansion bracket 51, the first end of the rotating component 52 is connected to the transmission mechanism 4, and the second end of the rotating component 52 is fixedly connected to the blade holder mounting component 55. The blade mounting component 56 is slidably mounted on the blade holder mounting component 55, one end of the blade mounting component 56 has a receiving groove 561 and the other end is connected to the blade 53. At this time, the telescopic component 54 includes a first elastic member 541 and a guide member 542. The first elastic member 541 is located in the receiving groove 561 and sleeved on the guide member 542. The blade holder mounting component 55 is provided with a limiting plate 551 in the rebound direction of the first elastic member 541, and one end of the guide member 542 is fixedly connected to the limiting plate 551. Among them, the first elastic element 541 is a spring, and the guide element 542 is a pin. Since the upper surface of the tremella fuciformis stick is not a plane, but a semi-circular surface with a high middle and low sides, the blade 53 will float up and down due to the extension and contraction of the spring along with the blade mounting part 56. This not only adapts to the uneven and irregular working environment of the tremella fuciformis stick, but also ensures the cutting depth, thereby ensuring that the film can be cut completely and reliably without damaging the mycelium.

[0055] like Figure 7 It is known that the rotating assembly 52 includes a rotating wheel 521, a limiting retaining ring 523, a rotating bearing 524, a transition ring 525, and a rotating shaft 522. The rotating shaft 522 is fitted with the rotating wheel 521, the limiting retaining ring 523, the rotating bearing 524, and the transition ring 525 sequentially from top to bottom on its outer side. The rotating wheel 521 serves as the first end of the rotating assembly 52 and is connected to the transmission mechanism 4. The rotating bearing 524 is fixed to the bearing seat 511 of the cavity expansion bracket 51. The limiting retaining ring 523 is positioned above the rotating bearing 524, and the transition ring 525 is positioned below the rotating bearing 524 and above the tool holder mounting component 55. The limiting retaining ring 523 limits the rotation of the rotating bearing 524, and the transition ring 525 isolates the rotating bearing 524 from the tool holder mounting component 55. In this embodiment, a rolling bearing 562 is also installed on the blade mount 56 near the blade 53. The lowest point of the rolling bearing 562 is higher than the lowest point of the blade 53 when in operation. Therefore, the rolling bearing 562 serves the following purpose:

[0056] (1) The tremella fuciformis stick is a solid object formed by wrapping the internal culture medium with an outer membrane. During the rotation and cutting process, the membrane of the cut part of the blade 53 is in a relaxed state and will warp, causing the blade to jam. If there is no rolling bearing 562 to cover and press, the blade 53 will get stuck in the stick, resulting in too much resistance and inability to cut.

[0057] (2) The surface of the mushroom log is a semi-circular arc surface, higher in the middle and lower on both sides. When the blade 53 rotates from the lower to the higher part of the mushroom log surface, the rolling bearing 562 smoothly climbs upward along the semi-circular arc surface, and the spring in the telescopic component 54 drives the blade 53 to rise automatically along the upward movement of the rolling bearing 562. The combined action of the rolling bearing 562 and the spring allows the blade 53 to smoothly cut from the lower to the higher part of the mushroom log surface. If the rolling bearing 562 is not used, but rather a rectangular limiting block, the limiting block and the blade 53 will get stuck in the culture medium and will be unable to continue cutting.

[0058] (3) The rolling bearing 562 helps guide the blade 53 to the upper surface of the tremella stick and to a certain extent limits the cutting depth of the blade 53.

[0059] like Figures 5 to 7 It is understood that the waste film treatment component 57 includes a guide block 576 and two inverted needle rods 571. The guide block 576 is disposed inside the rotating shaft 522 of the rotating component 52 and connected to the waste film support 512 by screws. One end of the inverted needle rod 571 is fixedly installed on the guide block 576, and the other end of the inverted needle rod 571 is conical, with its lowest point lower than the lowest point of the blade 53 in the working state. The two inverted needle rods 571 are located within the rotating circle of the blade 53. In this way, the inverted needle rod 571 will first contact the film on the tremella fuciformis stick and pass through it. Then, the blade 53 rotates to form a circular cut, and the waste film on this cut is hooked onto the head of the inverted needle rod 571. Afterwards, when the operator picks up the entire machine, the conical head is used to lift up the waste film cut by the blade 53, achieving the effect of waste film peeling.

[0060] In this embodiment, in addition to the bearing seat 511 mentioned above, the cavity expansion bracket 51 also includes a waste film bracket 512. The bearing seat 511 is flat and fits onto the main frame 1. The waste film bracket 512 is inverted U-shaped and has connecting holes extending at both ends of the U-shape for alignment with the connecting holes on the bearing seat 511. It is then fixed to the main frame 1 by screws, while the rotating wheel 521 is located between the bearing seat 511 and the waste film bracket 512. At this time, the waste film treatment assembly 57 of this embodiment also includes a limiting cap 572, a second elastic member 573, a waste film ejection rod 574, and a waste film ejection block 575. The waste film ejection rod 574 is slidably installed in the guide block 576. The second elastic member 573 is sleeved on the outer side of the extension of the waste film ejection rod 574 above the waste film support 512, and its end is connected to the limiting cap 572. The second elastic member 573 is located between the limiting cap 572 and the waste film support 512. The end of the waste film ejection rod 574 near the blade 53 is fixedly connected to the waste film ejection block 575. The waste film ejection block 575 is placed horizontally, and its two horizontal ends are respectively sleeved on the two inverted needle rods 571. The limiting cap 572 presses down to drive the waste film ejection rod 574 to slide downward and compress the second elastic member 573. The waste film ejection rod 574 drives the waste film ejection block 575 to slide downward along the inverted needle rod 571. At this time, when the operator presses the limit cap 572, the waste film ejection block 575 slides down along the needle bar 571, thereby ejecting the waste film from the needle bar 571 and causing it to fall. When the limit cap 572 is released, the second elastic element 573 rebounds and resets, thus completing one waste film ejection action.

[0061] In this embodiment, the second elastic element 573 is also a spring. The limiting cap 572 is screwed onto the waste film ejector rod 574, and the waste film ejector block 575 is also screwed onto the waste film ejector rod 574. The waste film ejector rod 574 can slide up and down within the inner groove of the guide block 576. Furthermore, the needle bar 571 is threaded onto the guide block 576, the limiting plate 551 is screwed onto the tool holder mounting component 55, the blade 53 is screwed onto the blade mounting component 56, and the pin is screwed onto the limiting plate 551. That is, the connection structure of each component uses screws or direct threads, which facilitates installation and ensures reliable and stable connection.

[0062] In this process, after expanding the planting holes of the tremella fuciformis sticks, the waste film needs to be peeled off and removed. The waste film peeling device designed in this embodiment can not only reliably peel off the waste film that sticks to the culture medium without damaging the culture medium, but also push the waste film into the designated collection device.

[0063] In summary, the working principle of this embodiment is as follows:

[0064] (1) The operator holds the handle 21 with both hands and lowers the entire machine vertically until the upper surface limiting plate 63 touches the upper surface of the tremella fuciformis stick. At the same time, the long side limiting plate 61 and the short side limiting plate 62 clamp the tremella fuciformis stick around its perimeter. At this time, the tremella fuciformis stick is limited around its perimeter.

[0065] (2) The motor 31 rotates, driving the three sets of blades 53 to rotate and cut the upper surface of the tremella fuciformis stick. After the cutting is completed, the hole expansion of the tremella fuciformis stick is completed.

[0066] (3) The operator holds the handle 21 with both hands and lifts the entire machine vertically upward to separate it from the tremella fuciformis stick. At this time, the cut waste film is carried up with the inverted needle rod 571. The operator manually pushes the limit cap 572 vertically downward three times. In this way, the waste film push-out block 575 pushes the waste film out from the inverted needle rod 571. Then the operator releases the spring limit cap 572 and the spring rebounds.

[0067] Repeat this process until a single tremella fuciformis spawn is cut off.

[0068] In this embodiment, the inverted needle rod 571 can stack 8 to 15 layers of waste film. Therefore, it is also possible to cut approximately 10 tremella fuciformis sticks and then push out all 10 layers of waste film from the inverted needle rod 571 at once.

[0069] Therefore, this embodiment limits the tremella fuciformis stick in all directions, and uses a motor 31 to cut three holes at the same time. The blade 53 can move up and down elastically with the upper surface of the tremella fuciformis stick, which ensures that the shape of the cut formed by expanding the hole is regular and the size is stable. Moreover, the hole expansion and membrane removal are completed in one operation. In addition, the overall design is more compact and lightweight, which ensures high operation efficiency, operation convenience and ease of operation for expanding the tremella fuciformis stick.
