Description

Technical Field

[0001] This utility model belongs to the field of edible fungi cultivation technology, and more specifically, it relates to a tool for turning over mushroom logs. Background Technology

[0002] Mushroom substrate is a culture medium for cultivating edible fungi such as shiitake mushrooms. By punching holes in it and inserting spawn, the spawn can germinate and grow inside the substrate. In the early stages of cultivation, the mycelium mainly spreads and develops inside the substrate; in the later stages, the mycelium breaks through the surface of the substrate and grows outward, eventually forming mature edible fungi (fruiting bodies).

[0003] In existing technologies, during the early stages of edible mushroom cultivation, mushroom logs are typically stacked: 2-4 logs per layer (currently, 4 logs per layer are used), with gaps between logs, and adjacent layers are stacked vertically and crosswise to reach the desired height. During this stage, the logs need to be rotated periodically (the positions of the logs at the top and bottom are swapped) to stimulate mycelial growth and dissipate heat from the stack. However, this rotation process requires operators to handle each log individually, resulting in low efficiency. Utility Model Content

[0004] This utility model provides a mushroom log turning tool that can transfer four mushroom logs at a time, thus improving the turning efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mushroom log turning tool is provided, comprising two sets of mating frames and two sets of clamping frames. The two sets of mating frames are arranged side-by-side and connected by a connecting frame. Each mating frame has two sets of mating rods symmetrically arranged on both sides of the middle portion of the mating frame. Each mating rod includes a first mating rod located at the end of the mating frame and extending downwards, and a second mating rod located inside the first mating rod and extending downwards. The two sets of clamping frames are rotatably connected to the connecting frame and located between the two sets of mating frames. Each set of clamping frames corresponds one-to-one with each of the two sets of mating rods. The outer end of each clamping frame has a first clamping rod located outside the first mating rod, and the clamping frame has a second clamping rod located inside the first clamping rod, with the second clamping rod located between the first and second mating rods. The clamping frame can swing vertically, allowing the first clamping rod to engage with the first mating rod and the second clamping rod to engage with the second mating rod, respectively, to clamp the mushroom log.

[0006] In one possible implementation, the connecting frame is provided with two connecting rods, which are respectively set with two sets of clamping frames. The connecting rods extend along the interval direction of the two sets of mating frames, and the clamping frames are rotatably connected to the connecting rods through rotating sleeves.

[0007] In some embodiments, a radially extending adjusting sleeve is connected to the outer peripheral wall of the rotating sleeve, the adjusting sleeve is slidably sleeved on the outer periphery of the clamping frame, and the adjusting sleeve is provided with a locking element for locking the clamping frame.

[0008] In some embodiments, the top of the connecting frame is provided with a guide rod that extends obliquely downward in an arc shape. The guide rod passes through the mating frame, and the mating frame can swing vertically and slide with the guide rod.

[0009] In some embodiments, the mounting bracket is provided with an elongated hole extending axially along the adjusting sleeve, and the guide rod is provided through the elongated hole.

[0010] In some embodiments, an elastic element is sleeved on the outer periphery of the guide rod between the mating frame and the connecting frame, and the elastic element can push the inner end of the mating frame downward.

[0011] In some embodiments, an upper lever is provided between the two sets of clamping frames and is slidably connected to the connecting frame in the vertical direction. The two ends of the upper lever extend to the lower part of the inner end of the two sets of clamping frames, and the upper lever can move upward and make the clamping frames swing vertically.

[0012] In some embodiments, the top of the connecting frame is provided with a slide bar that extends downward through the upper lever, and the upper lever is slidably connected to the slide bar.

[0013] In some embodiments, a limiting nut is threaded on the lower outer periphery of the slide bar. The limiting nut is located below the upper shift lever and abuts against the upper shift lever to limit the axial displacement of the upper shift lever.

[0014] In some embodiments, both ends of the upper lever are provided with sliding grooves that slide in conjunction with the inner ends of the two sets of clamping brackets.

[0015] Compared with the prior art, the mushroom stick turning tool provided in this embodiment, when in use, is aligned with the four mushroom sticks to be clamped, so that the first clamping rod and the corresponding first mating rod, as well as the second clamping rod and the corresponding second mating rod, all have mushroom sticks. Then, the connecting frame is grasped, and the fingers simultaneously apply force to the inner ends of the two clamping frames and swing them upward, thereby completing the simultaneous clamping of four mushroom sticks.

[0025] Mushroom substrate is a culture medium for cultivating edible fungi such as shiitake mushrooms. By punching holes in it and inserting spawn, the spawn can germinate and grow inside the substrate. In the early stages of cultivation, the mycelium mainly spreads and develops inside the substrate; in the later stages, the mycelium breaks through the surface of the substrate and grows outward, eventually forming mature edible fungi (fruiting bodies).

[0026] In existing technologies, during the early stages of edible mushroom cultivation, mushroom logs are typically stacked: 2-4 logs per layer (currently, 4 logs per layer are used), with gaps between logs, and adjacent layers are stacked vertically and crosswise to reach the desired height. During this stage, the logs need to be rotated periodically (the positions of the logs at the top and bottom are swapped) to stimulate mycelial growth and dissipate heat from the stack. However, this rotation process requires operators to handle each log individually, resulting in low efficiency.

[0027] Please see Figures 1 to 4 The mushroom log turning tool provided by this utility model will now be described. The mushroom log turning tool includes two sets of mating frames 10 and two sets of clamping frames 40. The two sets of mating frames 10 are arranged side-by-side and connected by a connecting frame 20. Each mating frame 10 has two sets of mating rods 30, symmetrically arranged on both sides of the middle portion of the mating frame 10. Each mating rod 30 includes a first mating rod 31 located at the end of the mating frame 10 and extending downwards, and a second mating rod 32 located inside the first mating rod 31 and extending downwards. The two sets of clamping frames 40 are rotatably connected to the connecting frame 20 and located on the two sets of... Between the mating frames 10, two sets of clamping frames 40 are arranged in a one-to-one correspondence with two sets of mating rods 30. The outer end of the clamping frame 40 is provided with a first clamping rod 41 located outside the first mating rod 31. The clamping frame 40 is provided with a second clamping rod 42 located inside the first clamping rod 41. The second clamping rod 42 is located between the first mating rod 31 and the second mating rod 32. The clamping frame 40 can swing vertically and make the first clamping rod 41 and the first mating rod 31, and the second clamping rod 42 and the second mating rod 32 respectively cooperate to clamp the mushroom stick 1.

[0028] This application provides a mushroom log turning tool. In actual use, the coordinated design of two sets of symmetrically matched frames 10 and clamping frames 40, through the precise alignment of the first clamping rod 41 with the first matching rod 31 and the second clamping rod 42 with the second matching rod 32, enables the simultaneous clamping of four mushroom logs 1 in a single action, significantly reducing the turning time.

[0029] The vertical swing design of the clamping frame 40 can adapt to different diameter mushroom sticks 1 without the need for manual adjustment tools, and can adapt to the specification fluctuations of mushroom sticks 1 in the production line.

[0030] The mating rods 30 on the same side of the two sets of mating frames 10 are used in conjunction with the corresponding clamping frames 40. That is, the first clamping rod 41 and the first mating rod 31 work together to clamp one mushroom stick 1, and the second clamping rod 42 and the second mating rod 32 work together to clamp one mushroom stick 1. A total of four mushroom sticks 1 can be clamped at the same time (e.g., Figure 1 (As shown).

[0031] In use, the mushroom stick 1 inverting tool is aligned with the four mushroom sticks 1 to be clamped, so that the first clamping rod 41 and the corresponding first mating rod 31, and the second clamping rod 42 and the corresponding second mating rod 32, all have mushroom sticks 1. Then, the connecting frame 20 is grasped, and the fingers simultaneously apply force to the inner ends of the two clamping frames 40 to swing upward, thereby completing the simultaneous clamping of the four mushroom sticks 1. After placing the clamped mushroom sticks 1 in the predetermined position using the mushroom stick 1 inverting tool, the clamping frames 40 are released to release the four mushroom sticks 1, realizing the transfer of four mushroom sticks 1 in a single operation and improving the inverting efficiency.

[0032] Compared with the prior art, the mushroom stick turning tool provided in this embodiment, when in use, is aligned with the four mushroom sticks 1 to be clamped, so that the first clamping rod 41 and the corresponding first mating rod 31 and the second clamping rod 42 and the corresponding second mating rod 32 both have mushroom sticks 1. Then, the connecting frame 20 is grasped, and the fingers simultaneously apply force to the inner ends of the two clamping frames 40 to swing upward, thereby completing the simultaneous clamping of four mushroom sticks 1. After placing the clamped mushroom sticks 1 in the predetermined position using the mushroom stick turning tool, the clamping frames 40 are released to release the four mushroom sticks 1, realizing the transfer of four mushroom sticks 1 in a single operation and improving the turning efficiency.

[0033] In one possible implementation, the aforementioned connecting frame 20 adopts, as shown in... Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The connecting frame 20 is provided with two connecting rods 21, which are corresponding to two sets of clamping frames 40. The connecting rods 21 extend along the interval direction of the two sets of mating frames 10, and the clamping frames 40 are rotatably connected to the connecting rods 21 through the rotating sleeve 50.

[0034] Specifically, the rotating sleeve 50 provides a rotation point for the rotation of the clamping frame 40, and the split design of the connecting rod 21 allows the two sets of clamping frames 40 to be disassembled and replaced independently, facilitating local maintenance or customized modifications.

[0035] The rotating sleeve 50 provides a single degree of rotational freedom (axial / radial locking), eliminating wear caused by lateral movement and extending the life of the oscillating component.

[0036] In some embodiments, see Figures 1 to 4 A radially extending adjusting sleeve 51 is connected to the outer peripheral wall of the rotating sleeve 50. The adjusting sleeve 51 is slidably sleeved on the outer periphery of the clamping frame 40. The adjusting sleeve 51 is provided with a locking member 52 for locking the clamping frame 40.

[0037] Specifically, the adjusting sleeve 51 slides to adjust the effective length of the clamping frame 40 by changing the lever ratio. It can also be adjusted according to the different diameters of the mushroom sticks 1, changing the distance between the first clamping rod 41 and the first mating rod 31, and the distance between the second clamping rod 42 and the second mating rod 32, thus improving the convenience of use.

[0038] Furthermore, the clamping bracket 40 has a long rod located inside the adjusting sleeve 51.

[0039] Furthermore, the locking member 52 is provided through the outer peripheral wall of the adjusting sleeve 51 and is threadedly connected to the adjusting sleeve 51. The locking member 52 can rotate and abut against the outer peripheral wall of the clamping bracket 40.

[0040] Specifically, the rotating abutment design forms a contact surface (which is better than point contact), and the locking element 52 can not only limit the axial displacement of the clamping frame 40, but also limit the rotation of the clamping frame 40 within the adjusting sleeve 51, thus ensuring the stability of clamping the mushroom stick 1.

[0041] In some embodiments, see Figures 1 to 4 The top of the connecting frame 20 is provided with a guide rod 60 that extends obliquely downward in an arc shape. The guide rod 60 passes through the mating frame 10, and the mating frame 10 can swing vertically and slide with the guide rod 60.

[0042] Specifically, the guide rod 60 passes through the mating frame 10 near the inner end. The downward arc-shaped extension path of the guide rod 60 provides a precise swing trajectory for the mating frame 10, ensuring that the mating rod 30 is always vertically aligned with the mushroom stick 1 during the clamping process, thus avoiding clamping failure caused by angular deviation due to the tilt of the mating frame 10.

[0043] In some embodiments, see Figures 1 to 4 The mounting bracket 10 has a long slot 43 extending axially along the adjusting sleeve 51, and the guide rod 60 is disposed through the long slot 43.

[0044] Specifically, the elongated hole 43 is provided on the long rod and extends along the axial direction of the long rod. It can cooperate with the clamping bracket 40 to adjust the position within the adjusting sleeve 51, thereby avoiding interference between the clamping bracket 40 and the guide rod 60 when adjusting the position and improving practicality.

[0045] In some embodiments, see Figures 1 to 4 The guide rod 60 is fitted with an elastic element 61 located between the mating frame 10 and the connecting frame 20. The elastic element 61 can push the inner end of the mating frame 10 downward.

[0046] Specifically, the elastic element 61 (such as a spring) continuously pushes the inner end of the mating frame 10 downwards, so that the tool automatically returns to the open state after releasing the mushroom stick 1, eliminating the need for manual reset and shortening the operation interval time.

[0047] The elastic element 61 absorbs the impact force during clamping, preventing the mushroom stick 1 from being damaged by rigid collision, especially protecting the surface mycelial activity and improving the yield.

[0048] In some embodiments, see Figures 1 to 4 Between the two sets of clamping frames 40, there is an upper lever 70 that is slidably connected to the connecting frame 20 in the vertical direction. The two ends of the upper lever 70 extend to the lower part of the inner end of the two sets of clamping frames 40 respectively. The upper lever 70 can move upward and make the clamping frames 40 swing vertically.

[0049] Specifically, the sliding connection design of the upper lever 70 enables the simultaneous operation of the double pressure clamp 40 with one hand: when moving upward, it directly lifts the inner end of the pressure clamp 40, and uses the lever principle to make the first pressure clamp 41 of the outer end approach the first cooperating rod 31 and the second pressure clamp 42 approach the second cooperating rod 32 to clamp the mushroom stick 1, thus reducing the operating force.

[0050] Workers can clamp the object by simply lifting the handle with one hand, avoiding bending over or using both hands, greatly reducing labor intensity and meeting the comfort requirements for long-term work.

[0051] Furthermore, the connecting frame 20 has a hand grip bar extending in a direction perpendicular to the interval between the two sets of mating frames 10. When in use, one hand can grip the hand grip bar tightly while the fingers hook onto the lever 70 to complete the clamping action.

[0052] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The top of the connecting frame 20 is provided with a slide bar 80 that extends downward through the upper lever 70, and the upper lever 70 is slidably connected to the slide bar 80.

[0053] Specifically, the slide bar 80 constrains the upper lever 70 to move only in the vertical direction, eliminating the clamping position deviation caused by lateral swaying and ensuring the consistency of the four clamping points.

[0054] The slide bar 80 and the connecting frame 20 form a closed force chain, which shares the reaction force during clamping, reduces the risk of tool deformation, and extends service life.

[0055] Furthermore, the upper lever 70 is provided with a through hole, the slide rod 80 is provided through the through hole, the outer peripheral wall of the slide rod 80 is provided with an axially extending positioning groove, and the inner peripheral wall of the through hole is provided with a positioning block located in the positioning groove.

[0056] In some embodiments, see Figure 4A limiting nut 81 is threaded on the lower outer circumference of the slide bar 80. The limiting nut 81 is located below the upper lever 70 and abuts against the upper lever 70 to limit the axial displacement of the upper lever 70.

[0057] Specifically, the limiting nut 81 precisely controls the clamping opening by adjusting the lower limit position of the upper lever 70 through the thread, adapting to stacking scenarios of mushroom sticks 1 of different heights.

[0058] The mechanical locking structure prevents the upper lever 70 from disengaging from the slide bar 80 during operation, ensuring the reliability of clamping.

[0059] In some embodiments, see Figure 3 and Figure 4 Both ends of the upper lever 70 are provided with sliding grooves 71 that slide in conjunction with the inner ends of the two sets of clamping brackets 40.

[0060] Specifically, the chute 71 allows the inner end of the clamping frame 40 to slide along a predetermined path during swinging, eliminating motion interference and ensuring that the clamping force is evenly transmitted to both ends of the mushroom stick 1.

[0061] The sliding contact surface reduces frictional loss, ensuring smooth operation even after long-term use and reducing maintenance frequency.

[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
