Description

Technical Field

[0001] The invention relates to the technical field of edible fungus cultivation, in particular to a special pallet for wood stacks. Background Art

[0002] Log cultivation is an important method for cultivating edible fungi. This method uses logs as a growth substrate for edible fungi. By inoculating the logs with edible fungi strains, the growth and development of mycelium is promoted under suitable environmental conditions, ultimately forming complete fruiting bodies. In large-scale log cultivation, after the logs are inoculated with edible fungi strains, the logs are usually stacked into piles and placed on pallets, awaiting transfer to the growth plant. From the time the edible fungi strains are inoculated to the time the logs are transferred to the growth plant, the log piles are typically stacked in the open air. The external light, humidity, and temperature conditions may not be suitable for the survival of the edible fungi strains, resulting in the partial death of the edible fungi strains planted on the logs, ultimately affecting the yield of the edible fungi. Summary of the Invention

[0003] The present invention provides a special pallet for wood piles, which improves the problem in the prior art that wood piles cannot provide a suitable living environment for edible fungi when stacked in the open air on the pallet, and can provide a suitable living environment for edible fungi on the wood piles.

[0004] To achieve the above object, the present invention provides a special pallet for wood stacks, comprising:

[0005] Tray body;

[0006] a first reel, wherein the number of the first reels is at least two, the two first reels being rotatably disposed on adjacent sides of the tray body, the rotational axes of the first reels being parallel to the edges of the tray body, the first reels being wound with a reflective film, and the ends of the reflective film being provided with a fixing structure;

[0007] A first fixed component, wherein the fixed structure is arranged on the side of the pallet body opposite to the first reel, and the fixed structure is detachably matched with the fixed structure. When in use, the wood segments are stacked on the pallet body to form a wood segment pile, and then the reflective film wound on the first reel is pulled out to cover the wood segment pile, and the fixed structure at the end of the reflective film is fixed to the first fixed component located on the opposite side of the first reel. The reflective film can reflect the sunlight shining on the wood segment pile, and prevent direct sunlight from killing the edible fungi on the wood segment under open air conditions. At the same time, the reflective film covering the wood segment pile can weaken the exchange between the wood segment pile and the outside air, which is beneficial to retaining moisture in the wood segment. In addition, because the reflective film reflects the sunlight shining on the wood segment pile and weakens the exchange between the wood segment pile and the outside air, it greatly weakens the ability of the outside world to exchange heat with the wood segment pile through two ways of thermal radiation and thermal convection, which is beneficial to maintaining a constant temperature of the wood segment. It can be seen that the special pallet for timber stacks of the present invention is beneficial for providing suitable light, humidity and temperature conditions for the timber logs and the edible fungi strains thereon, thereby improving the survival rate of the edible fungi strains and increasing the yield of edible fungi.

[0008] As an optional technical solution, it further includes a second scroll, which is arranged on the side of the tray body and is arranged opposite to one of the multiple first scrolls. The second scroll includes a hinged portion and a winding portion, the winding portion is connected to the hinged portion, and the reflective film is wound on the winding portion; the hinged portion is hinged to the tray body, and the hinged portion between the hinged portion and the tray body is located in the transition area between the adjacent two sides of the tray body. When in use, the hinged portion rotates relative to the tray body so that the winding portion rotates until its own axis is parallel to the height direction of the wood stack. At this time, the reflective film on the winding portion is pulled out, thereby wrapping the side of the wood stack and filling the gaps between the reflective films on the first scroll, which is conducive to further maintaining the stability of the light, humidity and temperature conditions of the edible fungi strains on the wood segments.

[0009] As an optional technical solution, the second reel further includes a housing, which is sleeved around the outer periphery of the winding portion and connected to the hinged portion. The housing has a split axially along the winding portion, through which the reflective film passes through the housing. A second fixing assembly is provided on the surface of the housing, which is removably engaged with the fixing structure. The housing protects the reflective film wound on the reel, thereby preventing the reflective film from being scratched by logs when stacked on the pallet body.

[0010] As an optional technical solution, the hinge portion includes a first surface and a second surface, the first surface and the second surface are arranged around the hinge axis of the hinge portion and the tray body and are connected to each other, the first surface is arranged opposite to the winding portion, the first surface is a curved surface, and the second surface is a flat surface;

[0011] The pallet body is provided with a locking device, comprising a mounting seat, a locking member, and a first elastic member. The mounting seat is provided corresponding to the hinge portion. The locking member is slidably connected to the mounting seat along the radial direction of the hinge axis between the hinge portion and the pallet body. The end of the locking member facing away from the mounting seat abuts against the first surface or the second surface. The first elastic member is connected to the locking member and the mounting seat. The first elastic member is used to apply a force to the locking member away from the mounting seat. When the second reel is in a retracted state, the axial direction of the winding portion is perpendicular to the height direction of the wood stack. At this time, the locking member abuts against the first surface. Since the first surface is an arc surface, the locking member cannot lock the first surface. The hinge portion can rotate along the hinge axis so that the axial direction of the winding portion is parallel to the height direction of the wood stack. At this time, the second surface slides until it abuts against the locking member, thereby causing the second reel to reach an unfolded state. Since the second surface is a plane, the locking member will limit the rotation of the hinge portion, so that the second reel remains in the unfolded state.

[0012] As an optional technical solution, the winding portion includes a winding drum, a support shaft, and a torsion spring, wherein the winding drum is sleeved on the outer circumference of the support shaft, the reflective film is wound on the winding drum, one end of the support shaft is connected to the hinge portion, and the torsion spring is arranged between the winding drum and the support shaft and sleeved on the support shaft, one end of the torsion spring is connected to the winding drum, and the other end is connected to the support shaft. When the reflective film wound on the winding portion is pulled out from the winding drum, the winding drum rotates relative to the support shaft, and the torsion spring is twisted and deformed, accumulating elastic potential energy until the reflective film is fully pulled out and fixed. When the reflective film needs to be retracted, the torsion spring recovers its deformation, releases its elastic potential energy, and drives the winding drum to rotate in the opposite direction, rewinding the reflective film.

[0013] As an optional technical solution, the winding part also includes a ratchet disc and a second elastic member, and there are two ratchet discs. The two ratchet discs are sleeved on the outer periphery of the support shaft, and one of them is connected to the winding drum, and the other is connected to one end of the second elastic member. The other end of the second elastic member abuts the hinge part, and the two ratchet discs are provided with ratchet teeth that are meshed and connected on the opposite sides. The ratchet teeth are used to mesh when the two ratchet discs rotate relative to each other in different directions or to push the two ratchet discs apart along the axial direction of the support shaft. When the reflective film is extended, the winding drum drives one of the ratchet discs connected to it to rotate relative to the other ratchet disc. At this time, the ratchet teeth on the two ratchet discs push the two ratchet discs to separate along the axial direction of the support shaft, and the winding drum can continue to rotate in this direction. At the same time, the second elastic member presses against the ratchet disc, so that the two ratchet discs cannot be separated; when the reflecting film is stopped, the elastic potential energy accumulated by the torsion spring causes the winding drum to have a tendency to rotate in the opposite direction. At this time, the ratchet teeth on the two ratchet discs engage with each other to prevent the winding drum from rotating under the action of the torsion spring, thereby maintaining the extended length of the reflective film; when the reflective film needs to be retracted, the second elastic member can be compressed to separate the two ratchet discs axially along the support shaft, so that the ratchet teeth on the two ratchet discs exit the meshing state. At this time, the torsion spring recovers its deformation, releases its elastic potential energy, drives the winding drum to rotate in the opposite direction, and rewinds the reflective film.

[0014] As an optional technical solution, the reflective film includes a central portion and multiple wing portions, the wing portions being connected to either side of the central portion along the axial direction of the first reel. The wing portions on either side of the central portion are folded toward each other, and the central portion is wound around the first reel. When the reflective film is wound around the first reel, the wing portions fold toward the central portion. When the reflective film is extended from the first reel, the wing portions can unfold away from the central portion, thereby filling the gap between two adjacent first reels.

[0015] As an optional technical solution, a ventilation pipe is provided inside the pallet body, and the ventilation pipe extends from one side of the pallet body to the other side in parallel with the axial direction of one of the plurality of first scrolls, and penetrates through the ventilation holes to the supporting surface of the pallet body. When the wood pile is wrapped by the reflective film, the wood pile is in a relatively closed state, and the heat and carbon dioxide generated by the respiration of the edible fungus cells are sealed inside the reflective film. In addition, the heat accumulated by sunlight will also accumulate inside the reflective film and is not easy to discharge, which will have an adverse effect on the survival of the edible fungus species. Air with a relatively suitable oxygen content and temperature can be introduced into the wood pile through the ventilation pipe and the ventilation holes to replace the gas in the reflective film, thereby providing suitable living conditions for the edible fungus species.

[0016] As an optional technical solution, the pallet body is provided with a connecting tenon and a connecting groove. The tenon and the connecting groove are correspondingly arranged and are respectively located on the side of the pallet body with the two end openings of the ventilation tube. The tenon and the connecting groove can be used to connect multiple dedicated wood stacking pallets into a row, and multiple sections of the ventilation tube are interconnected. In this case, only a single air source is required to supply air to the dedicated wood stacking pallets in the row.

[0017] As an optional technical solution, the pallet body is provided with a rib, the rib being arranged opposite to one of the plurality of first reels, so that the wood segments roll off when the wood segment stacking pallet is moved using a forklift or other tool.

[0018] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0019] The present invention provides a pallet specifically designed for wood piles. A first reel is provided on the pallet body, and a first fixing assembly is provided on the opposite side of the first reel. A reflective film is wound around the first reel. During use, the reflective film can be pulled out of the first reel to cover the wood pile, and the end of the reflective film is fixed to the first fixing assembly. This reduces the intensity of sunlight on the wood pile, reduces heat exchange between the wood pile and the external environment, and prevents evaporation of moisture within the wood. This provides suitable light, humidity, and temperature conditions for the wood piles and the edible fungi strains grown thereon, thereby improving the survival rate of the edible fungi strains and increasing the yield of the edible fungi.

[0033] Example 1

[0034] The present invention provides a pallet specifically designed for stacking wood segments, comprising a pallet body 1, a first reel 2, and a first fixing assembly 4. There are at least two first reels 2, rotatably disposed on adjacent sides of the pallet body 1, with the rotational axes of the first reels 2 parallel to the edges of the pallet body 1 on which they are located. A reflective film 3 is wound around the first reels 2, with a fixing structure 31 disposed at the end of the reflective film 3. The fixing structure 31 is disposed on the side of the pallet body 1 opposite the first reel 2, and the fixing structure 31 is detachably engaged with the fixing structure 31.

[0035] During use, the timber sections are stacked on the pallet body 1 to form a timber section pile. The reflective film 3 wound on the first reel 2 is then pulled out and covered on the timber section pile, and the fixing structure 31 at the end of the reflective film 3 is fixed to the first fixing assembly 4 located on the opposite side of the first reel 2. The reflective film 3 can reflect the sunlight shining on the timber section pile, preventing direct sunlight from killing the edible fungi on the timber sections under open air conditions. At the same time, the reflective film 3 covering the timber section pile can reduce the exchange between the timber section pile and the outside air, which is conducive to retaining moisture in the timber sections. In addition, because the reflective film 3 reflects the sunlight shining on the timber section pile and reduces the exchange between the timber section pile and the outside air, it greatly weakens the ability of the outside world to exchange heat with the timber section pile through two pathways of thermal radiation and thermal convection, which is conducive to maintaining a constant temperature of the timber sections. As can be seen, the timber section pile special pallet of the present invention is conducive to providing suitable light, humidity and temperature conditions for the timber sections and the edible fungi on them, thereby improving the survival rate of the edible fungi and increasing the yield of edible fungi.

[0036] Among them, the fixing structure 31 can be a fixing ring, a fixing pin, or a protrusion or thickened layer set or installed at the end of the reflective film 3; the first fixing component 4 can be a protruding pin, a hole or a clip, etc.; the reflective film 3 can be a plastic film with a reflective coating or a foam insulation film, etc., which is not limited in this embodiment.

[0037] Example 2

[0038] On the basis of the first embodiment, the second reel 5 is further included. The second reel 5 is arranged on the side of the tray body 1 and is arranged opposite to one of the multiple first reels 2. The second reel 5 includes a hinge portion 51 and a winding portion. The winding portion is connected to the hinge portion 51 and is wound with a reflective film 3. The hinge portion 51 is hinged to the tray body 1, and the hinge portion of the hinge portion 51 and the tray body 1 is located in the transition area between the adjacent two sides of the tray body 1. During use, the hinge portion 51 rotates relative to the tray body 1, causing the winding portion to rotate until its own axis is parallel to the height direction of the wood stack. At this time, the reflective film 3 on the winding portion is pulled out, thereby wrapping the side of the wood stack and filling the gaps between the reflective films 3 on the first reel 2, which is conducive to further maintaining the stability of the light, humidity and temperature conditions of the edible fungi strains on the wood stack.

[0039] As an optional embodiment, the second reel 5 further includes a housing 52, which is sleeved around the outer periphery of the winding portion and connected to the hinge portion 51. The housing 52 has a slit along the axial direction of the winding portion, through which the reflective film 3 passes. A second fixing assembly is provided on the surface of the housing 52, which is detachably engaged with the fixing structure 31. The housing 52 protects the wound reflective film 3, preventing it from being scratched by logs when stacked on the pallet body 1.

[0040] The second fixing component may be a protruding pin, a hole, a clip, etc., which is not limited in this embodiment.

[0041] As an optional embodiment, the hinge portion 51 includes a first surface 511 and a second surface 512. The first surface 511 and the second surface 512 are arranged around the hinge axis between the hinge portion 51 and the tray body 1 and are connected to each other. The first surface 511 is arranged opposite to the winding portion. The first surface 511 is an arcuate surface, and the second surface 512 is a flat surface.

[0042] A locking device is provided on the tray body 1, which includes a mounting seat 11, a locking member 12 and a first elastic member. The mounting seat 11 is arranged corresponding to the hinge portion 51, and the locking member 12 is connected to the mounting seat 11 along the radial sliding of the hinge portion 51 and the hinge axis of the tray body 1. The end of the locking member 12 facing away from the mounting seat 11 abuts against the first surface 511 or the second surface 512, and the first elastic member is connected to the locking member 12 and the mounting seat 11. The first elastic member is used to apply a force to the locking member 12 away from the mounting seat 11. When the second reel 5 is in the retracted state, the axial direction of the winding portion is perpendicular to the height direction of the wood stack. At this time, the locking piece 12 abuts against the first surface 511. Since the first surface 511 is an arc surface, the locking piece 12 cannot lock the first surface 511. The hinged portion 51 can rotate along the hinge axis so that the axial direction of the winding portion is parallel to the height direction of the wood stack. At this time, the second surface 512 slides to abut against the locking piece 12, so that the second reel 5 reaches the unfolded state. Since the second surface 512 is a plane, the locking piece 12 will limit the rotation of the hinged portion 51, so that the second reel 5 remains in the unfolded state.

[0043] The first elastic member may be a spring, a metal dome, a silicone or a rubber pad, etc., which is not limited in this embodiment.

[0044] As an optional embodiment, the winding portion includes a winding drum 53, a support shaft 54, and a torsion spring 55. The winding drum 53 is sleeved around the support shaft 54, and the reflective film 3 is wound around the winding drum 53. One end of the support shaft 54 is connected to the hinge portion 51. The torsion spring 55 is disposed between the winding drum 53 and the support shaft 54 and sleeved around the support shaft 54. One end of the torsion spring 55 is connected to the winding drum 53, and the other end is connected to the support shaft 54. When the reflective film 3 wound on the winding portion is pulled out from the winding drum 53, the winding drum 53 rotates relative to the support shaft 54, causing the torsion spring 55 to twist and deform, accumulating elastic potential energy until the reflective film 3 is fully pulled out and secured. When the reflective film 3 needs to be retracted, the torsion spring 55 recovers its deformation, releasing its elastic potential energy, driving the winding drum 53 to rotate in the opposite direction, and rewinding the reflective film 3.

[0045] As an optional embodiment, the winding portion also includes a ratchet disc 56 and a second elastic member 57. There are two ratchet discs 56. The two ratchet discs 56 are sleeved on the outer periphery of the support shaft 54, and one of them is connected to the winding drum 53, and the other is connected to one end of the second elastic member 57. The other end of the second elastic member 57 abuts against the hinge portion 51. The two ratchet discs 56 are provided with ratchet teeth 561 that are meshed and connected on the opposite sides. The ratchet teeth 561 are used to mesh when the two ratchet discs 56 rotate relative to each other in different directions or to push the two ratchet discs 56 to separate along the axial direction of the support shaft 54. When the reflective film 3 is extended, the winding drum 53 drives one of the ratchet discs 56 connected to it to rotate relative to the other ratchet disc 56. At this time, the ratchet teeth 561 on the two ratchet discs 56 push the two ratchet discs 56 apart along the axial direction of the support shaft 54, and the winding drum 53 can continue to rotate in this direction. At the same time, the second elastic member 57 presses against the ratchet discs 56, so that the two ratchet discs 56 cannot be separated. When the pulling of the reflective film 3 stops, the elastic potential energy accumulated in the torsion spring 55 causes the winding drum 53 to rotate in the opposite direction. When the reflective film 3 needs to be retracted, the second elastic member 57 can be compressed to separate the two ratchet discs 56 axially along the support shaft 54, so that the ratchet teeth 561 on the two ratchet discs 56 are out of engagement. At this time, the torsion spring 55 recovers its deformation, releases its elastic potential energy, and drives the winding drum 53 to rotate in the opposite direction, so as to rewind the reflective film 3.

[0046] The second elastic member 57 may be a spring, a metal dome, a silicone or rubber pad, etc., which is not limited in this embodiment.

[0047] It should be noted that a torsion spring 55 , a ratchet disc 56 , a second elastic member 57 or similar structures may also be provided on the first reel 2 .

[0048] As an optional embodiment, the reflective film 3 includes a central portion 31 and multiple wing portions 32. The wing portions 32 are connected to both sides of the central portion 31 along the axial direction of the first reel 2. The wing portions 32 on both sides of the central portion 31 are folded toward each other, and the central portion 31 is wound around the first reel 2. When the reflective film 3 is wound around the first reel 2, the wing portions 32 fold toward the central portion 31. When the reflective film 3 is extended from the first reel 2, the wing portions 32 can unfold away from the central portion 31, thereby filling the gap between two adjacent first reels 2.

[0049] As an optional embodiment, a ventilation pipe 13 is provided inside the pallet body 1. The ventilation pipe 13 extends from one side of the pallet body 1 to the other side in parallel with the axial direction of one of the multiple first scrolls 2, and penetrates the supporting surface of the pallet body 1 through the ventilation holes. When the wood pile is wrapped in the reflective film 3, the wood pile is in a relatively closed state. The heat and carbon dioxide generated by the respiration of the edible fungus cells are enclosed inside the reflective film 3. In addition, the heat accumulated by sunlight will also accumulate inside the reflective film 3 and is not easy to discharge, which will have an adverse effect on the survival of the edible fungus species. Air with a relatively suitable oxygen content and temperature can be introduced into the wood pile through the ventilation pipe 13 and the ventilation holes to replace the gas in the reflective film 3, thereby providing suitable living conditions for the edible fungus species.

[0050] As an optional embodiment, the pallet body 1 is provided with a connecting tenon 14 and a connecting groove. The tenon 14 and the connecting groove are arranged correspondingly and are respectively located on the side of the pallet body 1 where the ventilation tube 13 has two openings at both ends. The tenon 14 and the connecting groove can be used to connect multiple wood stacking pallets into a row, and the multiple ventilation tubes 13 are interconnected. In this case, only a single air source is required to supply air to the wood stacking pallets in the row.

[0051] In addition, the connecting tenon 14 can also serve as the first fixing component 4 , cooperating with the fixing structure 31 to fix the reflective film 3 .

[0052] As an optional embodiment, the pallet body 1 is provided with a rib, which is arranged opposite to one of the plurality of first reels 2. The rib allows the wood to roll off when the wood stacking pallet is moved using a forklift or other tool.
