Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a portable tremella mushroom stick hole expanding machine. Background Art

[0002] During the growth of Tremella, due to the small size of the inoculation port, it is not enough for the subsequent growth of Tremella, and it is necessary to expand the hole to expand the hole. In domestic production, a utility knife is generally used to expand the hole manually, resulting in inconsistency and instability in the size and shape of the incision. If the incision size is too small, the hole expansion effect cannot be achieved. If the incision size is too large, in addition to the Tremella mushroom stick being easily contaminated and affecting the yield or even scrapping, it may also cause the Tremella to grow and mature. The contact area between the Tremella and the culture medium is too large, resulting in the difficulty and workload of removing the Tremella ear base when the Tremella is harvested. Therefore, the existing artificial hole expansion will affect the yield and quality of Tremella. Utility Model Content

[0018] The beneficial effects of the utility model are:

[0019] (1) The incision formed by the hole expansion of the utility model has a regular shape and stable size.

[0020] The existing artificial hole expansion is elliptical, and the hole expansion mouth is long or short. The hole expansion mouth that is too long will not only cause the Tremella to contact too much with the culture medium of the mushroom stick, resulting in the Tremella being contaminated, thus affecting the yield or even scrapping; but also will cause the Tremella to produce too many ear bases when harvesting, increasing the work of removing the ear bases, reducing the weight of the effective Tremella, and reducing the income of farmers. The hole expansion mouth that is too short cannot meet the nutrients required for the growth of Tremella, resulting in low Tremella yield and reduced income for farmers. The incision formed by the hole expansion of the utility model has a regular shape and stable size. By changing the cutting size of the hole expansion mechanism, the hole can be expanded to an incision size suitable for the healthy production of Tremella, which is helpful for the Tremella appearance and improves the stability of the good Tremella appearance. It is ultimately beneficial to farmers, bringing them more income and less cost, including the cost of hole expansion and ear base removal.

[0021] (2) The utility model realizes single-handed portable acupuncture hole expansion.

[0022] At present, most of the hole expansion workers are middle-aged and elderly female workers who are unable to undertake heavy physical labor. However, the utility model is light in weight and compact in size, so it can be held by one person with one hand. During the hole expansion stage, the mushroom sticks are stored in layers of steel frames one by one in an orderly interval. Therefore, the worker can hold the device in one hand and move the mushroom sticks from the steel frame to the position where the hole needs to be expanded in the other hand, expand all the holes on the mushroom sticks in turn, and then put them back, which reduces the labor intensity and improves work efficiency. The utility model can achieve machine-assisted manual hole expansion through a simple and compact structural design.

[0023] (3) The utility model can stably, reliably and completely cut the upper surface of the mushroom stick.

[0024] The mushroom stick is wrapped with the culture medium inside by the outer membrane to form a solid object. The membrane of the cut part of the blade is in a loose state during the rotary cutting process, which will bend and cause the blade to get stuck. If there is no rolling bearing to cover the pressure, the blade will sink into the mushroom stick, so that the resistance is too large and it cannot be cut; at the same time, the rolling bearing also plays a role in limiting the cutting depth of the blade. Secondly, the surface of the mushroom stick is a quasi-arc surface with a high middle and low sides. When the blade rotates from low to high on the surface of the mushroom stick, the rolling bearing climbs smoothly upward along the quasi-arc surface, and the spring in the retractable component drives the blade to automatically rise along the upward movement of the rolling bearing. The combined action of the rolling bearing and the spring enables the blade to smoothly cut from low to high on the surface of the mushroom stick. If a rectangular stop block is used instead of a rolling bearing, the stop block and the blade will sink into the culture medium together and cannot continue cutting. In addition, the blade of the utility model does not need to be positioned by a sensor to allow the blade to always cut at the same starting point, and can be cut at any position of the travel radius to achieve complete cutting.

[0025] (4) The utility model can complete the hole expansion and mold taking in one go.

[0026] The utility model places a conical inverted needle rod in a hollow rotating shaft, designs a suitable taper and a barb of the conical inverted needle rod, and in a narrow space, does not require electricity to provide a power source, and simultaneously takes away the waste film when the machine is separated from the tremella mushroom stick, thereby achieving the effect of completing the hole expansion and mold taking in one step.

DETAILED DESCRIPTION

[0040] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] Embodiment 1

[0042] Please refer to Figures 1 to 7 A portable Tremella fuciformis stick hole expanding machine comprises a main frame 1, a handheld portion 2, a driving mechanism 3, a transmission mechanism 4, a positioning mechanism 6 and a single hole expanding mechanism 5, wherein the hole expanding mechanism 5 is arranged on the main frame 1, the driving mechanism 3 and the transmission mechanism 4 are arranged on the main frame 1 and are located on one side of the hole expanding mechanism 5, the handheld portion 2 is located above the hole expanding mechanism 5, the driving mechanism 3 is connected to the transmission mechanism 4, and the transmission mechanism 4 is transmission-connected to the hole expanding mechanism 5.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7It can be seen that the driving mechanism 3 includes a motor 31 and a reducer 32, and the transmission mechanism 4 includes a synchronous wheel 41 and a synchronous belt 42. The reducer 32 and the synchronous wheel 41 are both fixed on the main frame 1. The motor 31 is connected to the synchronous wheel 41 through the reducer 32, and one end of the synchronous belt 42 is sleeved on the synchronous wheel 41 and the other end is sleeved on the first end of the rotating component 52. That is, the rotating component 52 is driven to rotate by the motor 31 through the reducer 32, the synchronous wheel 41 and the synchronous belt 42.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 It can be seen that the positioning mechanism 6 is arranged on the side of the main frame 1 where the blade 53 is located, and the positioning mechanism 6 includes a short side limiting plate 61 and an upper surface limiting plate 62. One upper surface limiting plate 62 is respectively arranged on both sides of the hole expanding mechanism 5, and one short side limiting plate 61 is respectively arranged on the other two sides of the hole expanding mechanism 5. The lowest point of the upper surface limiting plate 62 in the working state is higher than the lowest point of the short side limiting plate 61; in this way, the two upper surface limiting plates 62 are fixed on the upper surface of the Tremella fuciformis stick, and the lower ends of the two short side limiting plates 61 are inclined in a direction away from each other, thereby playing a guiding role in the process of the short side limiting plates 61 moving downward, making it convenient for the short side limiting plates 61 to be fixed on both sides of the Tremella fuciformis stick, thereby ensuring the stability of the Tremella fuciformis stick when being cut.

[0045] Reference Figures 4 to 7 ,in, Figure 4 and Figure 5 The schematic diagrams of the hole expansion mechanism 5 are obtained from the three-dimensional perspectives of looking down and looking up respectively. Figure 6 Front view and Figure 7 The cross-sectional view serves as a comparison between the inside and the outside, making it easier for technicians to understand the utility model.

[0046] Specifically, if Figure 6 and Figure 7It can be known that the hole expansion mechanism 5 includes a hole expansion bracket 51, a rotating assembly 52, a telescopic assembly 54, a knife holder mounting member 55, a blade mounting member 56, a blade 53 and a waste film processing assembly 57. The hole expansion bracket 51 is fixed to the main frame 1, the rotating assembly 52 is mounted on the hole expansion bracket 51, the first end of the rotating assembly 52 is connected to the transmission mechanism 4, the second end of the rotating assembly 52 is fixedly connected to the knife holder mounting member 55, the blade mounting member 56 is slidably arranged on the knife holder mounting member 55, one end of the blade mounting member 56 is provided with a receiving groove 561 and the other end is connected to the blade 53. At this time, the telescopic assembly 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 is sleeved outside the guide member 542, the knife holder mounting member 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 member 541 is a spring, and the guide member 542 is a pin. Since the upper surface of the Tremella fuciformis stick is not a plane, but an arc-like surface with a high middle and low sides, the blade 53 will float up and down following the blade mounting member 56 under the influence of the expansion and contraction of the spring. This not only adapts to the uneven and irregular working scene of the Tremella fuciformis stick surface, but also ensures the cutting depth, thereby ensuring that the film can be cut off completely and reliably without damaging the mycelium.

[0047] like Figure 7 It can be seen that the rotating assembly 52 includes a rotating wheel 521, a limiting snap ring 523, a rotating bearing 524, a transition ring 525 and a rotating shaft 522. The rotating wheel 521, the limiting snap ring 523, the rotating bearing 524 and the transition ring 525 are sleeved on the outer side of the rotating shaft 522 in sequence from top to bottom. The rotating wheel 521 is connected to the transmission mechanism 4 as the first end of the rotating assembly 52. ​​The rotating bearing 524 is fixed on the bearing seat 511 of the hole expansion bracket 51. The limiting snap ring 523 is arranged above the rotating bearing 524. The transition ring 525 is arranged below the rotating bearing 524 and above the tool holder mounting member 55. Among them, the limiting snap ring 523 plays a role in limiting the rotating bearing 524, and the transition ring 525 plays a role in isolating the rotating bearing 524 and the tool holder mounting member 55. In this embodiment, the blade mounting member 56 is further provided with a rolling bearing 562 at a position close to the blade 53. The lowest point of the rolling bearing 562 in the working state is higher than the lowest point of the blade 53. Thus, the provision of the rolling bearing 562 plays the following roles:

[0048] (1) The Tremella fuciformis stick is formed into a solid object by wrapping the internal culture medium with the external membrane. During the rotary cutting process of the blade 53, the cut part of the membrane is in a loose state and may warp, resulting in the blade getting stuck. Without the rolling bearing 562 for covering pressure, the blade 53 may sink into the stick, resulting in too great resistance to be able to cut.

[0049] (2) The surface of the mushroom stick is a quasi-arc surface with a high middle and low sides. When the blade 53 rotates from a low position to a high position on the surface of the mushroom stick, the rolling bearing 562 smoothly climbs upward along the quasi-arc surface, and the spring in the retractable component 54 drives the blade 53 to automatically rise along the upward movement of the rolling bearing 562. The combined action of the rolling bearing 562 and the spring enables the blade 53 to smoothly cut from a low position to a high position on the surface of the mushroom stick. If a rectangular stop block is used instead of the rolling bearing 562, the stop block and the blade 53 will be trapped in the culture medium together, and cutting will not be able to continue.

[0050] (3) The rolling bearing 562 helps the blade 53 to guide the upper surface of the Tremella fuciformis stick and, to a certain extent, limits the cutting depth of the blade 53.

[0051] like Figures 5 to 7 It can be seen that the waste film processing assembly 57 includes a guide block 576 and two needle rods 571. The guide block 576 is arranged in the rotating shaft 522 of the rotating assembly 52 and is connected to the waste film bracket 512 by screws. One end of the needle rod 571 is fixedly installed on the guide block 576. The other end of the needle rod 571 is conical and the lowest point in the working state is lower than the lowest point of the blade 53. The two needle rods 571 are located within the rotating circle of the blade 53. In this way, the 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 incision. The waste film on this incision is hooked on the head of the needle rod 571. Then, when the operator picks up the entire machine, the waste film cut by the blade 53 is brought up by the cone of the head, so as to achieve the effect of stripping the waste film.

[0052] In this embodiment, in addition to the above-mentioned bearing seat 511, the hole expansion bracket 51 also includes a waste film bracket 512. The bearing seat 511 is flat and fits on the main frame 1. The waste film bracket 512 is in an inverted U shape and has extended connecting holes at both ends of the U, which are used to align with the connecting holes on the bearing seat 511 and then fixed to the main frame 1 by screws. The rotating wheel 521 is located between the bearing seat 511 and the waste film bracket 512. At this time, the waste film processing assembly 57 of this embodiment also includes a limiting cap 572, a second elastic member 573, a waste film pushing rod 574 and a waste film pushing block 575. The waste film pushing rod 574 can be slidably installed in the guide block 576. The waste film pushing rod 574 is located on the outer side of the extension portion above the waste film support 512 and is sleeved with the second elastic member 573 and its end is connected to the limiting cap 572, and the second elastic member 573 is located between the limiting cap 572 and the waste film support 512; the end of the waste film pushing rod 574 close to the blade 53 is fixedly connected to the waste film pushing block 575, the waste film pushing block 575 is horizontally placed and the horizontal ends are respectively sleeved on the two inverted needle rods 571, the limiting cap 572 is pressed downward to drive the waste film pushing rod 574 to slide downward and compress the second elastic member 573, and the waste film pushing rod 574 drives the waste film pushing block 575 to slide downward along the inverted needle rod 571. At this time, when the operator presses the limiting cap 572, the waste film pushing block 575 is driven to slide downward along the needle rod 571, thereby pushing the waste film off the needle rod 571. When the limiting cap 572 is released, the second elastic member 573 rebounds to achieve reset, thereby completing a waste film pushing action.

[0053] In this embodiment, the second elastic member 573 is also a spring. Among them, the limit cap 572 is installed on the waste film push rod 574 by screws, and the waste film push block 575 is also installed on the waste film push rod 574 by screws. The waste film push rod 574 is placed in the inner groove of the guide block 576 to slide up and down. In addition, the needle rod 571 is installed on the guide block 576 by threading, the limit plate 551 is installed on the knife holder mounting member 55 by screws, the blade 53 is installed on the blade mounting member 56 by screws, and the pin is installed on the limit plate 551 by screws, that is, the connection structure of each component adopts a screw or direct thread connection method, which is easy to install and the connection is reliable and stable.

[0054] The handheld part 2 of this embodiment is located above the limiting cap 572 and is directly connected to the hole expansion bracket 51. Specifically, the handheld part 2 of this embodiment is connected to the waste film bracket 512 by screws to avoid occupying space, so as to make the machine more compact and easy to carry. There is a space for the hand to be inserted between the handheld part 2 and the limiting cap 572, so that the operator can insert his hand into the limiting cap 572 to press down.

[0055] Among them, the waste film needs to be peeled off and removed after the Tremella fuciformis sticks are expanded. The waste film peeling device designed in this embodiment can not only reliably peel off the waste film that is adhered to the culture medium without damaging the culture medium, but also push the waste film out and drop it into a designated collection device.

[0056] In summary, the working principle of this embodiment is as follows:

[0057] (1) The operator moves the mushroom stick outward from the steel frame to the first expanded hole to a suitable position with one hand, and holds the handheld part 2 with the other hand to move the entire machine vertically downward until the upper surface limiting plate 62 touches the upper surface of the Tremella fuciformis mushroom stick, and at the same time, the short side limiting plates 61 clamp the two sides of the Tremella fuciformis mushroom stick and align the positions on the Tremella fuciformis mushroom stick where the holes are to be cut with the eyes;

[0058] (2) The motor 31 rotates, driving the blade 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;

[0059] (3) The operator holds the handheld part 2 with one hand and moves the whole machine vertically upwards to separate from the Tremella fuciformis stick. At this time, the cut waste film is brought up together with the needle rod 571, and the limiting cap 572 is manually pushed to move vertically downward, so that the waste film pushing block 575 pushes the waste film from the needle rod 571 to the designated collection device; then the operator releases the spring limiting cap 572 by hand, and the spring force rebounds;

[0060] Repeat the above steps, cut the second and third expanded hole openings in turn, and put the mushroom stick back to its original place; repeat this process and cut the next Tremella fuciformis mushroom stick.

[0061] Among them, the inverted needle rod 571 of this embodiment can stack 8 to 15 layers of waste film. Therefore, after cutting about 4 Tremella fuciformis sticks, 12 layers of waste film can be pushed out from the inverted needle rod 571 at one time.

[0062] Therefore, this embodiment positions the Tremella fuciformis stick, drives the blade 53 through the motor 31 to cut the hole, and allows the blade 53 to elastically float up and down following the upper surface of the Tremella fuciformis stick, thereby ensuring that the incision formed by expanding the hole has a regular shape and stable size; and the hole expansion and membrane removal are completed in one operation, and the overall design is more compact and lightweight, ensuring high operating efficiency, convenience and ease of operation for expanding the hole of the Tremella fuciformis stick.
