Abstract
Description
Technical Field
[0001] This utility model relates to the field of large fungal collection technology, specifically a device for collecting and preserving large fungi. Background Technology
[0002] When collecting large fungi, hold the mushroom column firmly with one hand to stabilize its position, and use sharp scissors to precisely cut along the base of the stem with the other hand, or gently pick it off, ensuring that the basal tissue is preserved to stimulate subsequent fruiting. The harvested fresh mushrooms should be immediately placed in a clean plastic crate, ensuring they are laid out in layers and not crushed. Then, quickly transfer the crate to a well-ventilated and dry place to prepare for subsequent drying, ensuring minimal mechanical damage and humidity fluctuations throughout the process.
[0003] Currently, most plastic crates used for harvesting and preserving fresh mushrooms are manufactured using a one-piece molding process, lacking an internal layered structure, which means that fresh mushrooms can only be stored by simply stacking them. This disorderly stacking method has significant drawbacks: on the one hand, the weight of the fresh mushrooms on top can easily compress the caps of the lower layers (such as agaric mushrooms), causing mechanical breakage; varieties with slender stems (such as polypore mushrooms) may break due to compression; on the other hand, the stacked state hinders air circulation, inhibits the normal evaporation of moisture from the fresh mushrooms, and leads to increased local humidity, which in turn accelerates the growth of microorganisms and the process of spoilage. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a device for collecting and preserving large fungi, preventing fresh mushrooms from being stacked and damaged.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for collecting and preserving large fungi, comprising a frame, a slot provided on one side of the middle position of the frame, a partition slidably connected inside the slot, a positioning ring provided at the bottom of the partition, and the outer wall of the positioning ring being fixedly connected to the inner wall of the frame.
[0006] Furthermore, the frame is provided with trays at both ends near the slot, and the trays are fixedly connected to the frame.
[0007] Furthermore, a handle is fixed to the side of the partition away from the frame.
[0008] Furthermore, positioning grooves are provided at both ends of the partition away from the frame, and positioning blocks are slidably connected inside the positioning grooves, with storage boxes fixed to the top of the positioning blocks.
[0009] Furthermore, an iron sheet is fixedly connected to the lower end of the storage box near the frame, and a permanent magnet is fixedly connected to the side wall of the frame, with the iron sheet and the permanent magnet attracting each other.
[0010] Furthermore, the storage box and positioning block have through slots inside, and the partition has cooling slots inside, which are connected to the through slots.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The collection and preservation device for this type of large fungus involves placing a layer of fresh mushrooms inside the frame, then inserting a partition into a slot, and finally placing fresh mushrooms on the partition. This prevents the fresh mushrooms from being stacked and damaged. At the same time, the unstacked fresh mushrooms allow for ventilation gaps between them, facilitating air circulation and slowing down the growth of microorganisms and the process of spoilage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figure 1-5 A device for collecting and preserving large fungi includes a frame 1, a slot is provided on one side of the middle position of the frame 1, a partition 3 is slidably connected inside the slot, a positioning ring 2 is provided at the bottom of the partition 3, and the outer wall of the positioning ring 2 is fixedly connected to the inner wall of the frame 1.
[0021] The large fungus collection and preservation device of this utility model allows for the placement of a layer of fresh mushrooms at the bottom inner side of the frame 1. After this layer is placed, a partition 3 can be inserted into a slot from one side of the frame 1. Fresh mushrooms are then placed on the partition 3 to prevent the mushrooms from being damaged due to stacking. At the same time, the unstacked mushrooms allow for ventilation gaps between them, facilitating air circulation and slowing down the growth and decay of microorganisms. The positioning ring 2 provides support for the partition 3, preventing it from bending downwards and causing the lower layer of fresh mushrooms to be squeezed and damaged.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the frame 1 has a support plate 10 at both ends near the slot, and the support plate 10 is fixedly connected to the frame 1.
[0023] Specifically, before inserting the partition 3 into the slot, one side of the partition 3 can be placed on the support plate 10 to make it easier to insert the partition 3 into the slot of the frame 1.
[0024] like Figure 2 As shown, a handle 4 is fixed to the side of the partition 3 away from the frame 1.
[0025] Specifically, it is more effortless and convenient to pull the partition 3 by using the handle 4.
[0026] like Figure 2 , Figure 3 and Figure 5 As shown, positioning grooves 5 are provided at both ends of the partition 3 on the side away from the frame 1. Positioning blocks 6 are slidably connected inside the positioning grooves 5, and storage boxes 7 are fixedly connected to the top of the positioning blocks 6.
[0027] Specifically, after the partition 3 is fully inserted into the slot, the positioning block 6 can be aligned with the positioning groove 5, and then the storage box 7 and the positioning block 6 can be moved downward together to insert the positioning block 6 into the positioning groove 5, thereby preventing the partition 3 from detaching from the frame 1. At the same time, the storage box 7 can hold some miscellaneous items, such as: harvesting knife, root digger, pruning shears, or plastic wrap used to wrap the top of the frame 1.
[0028] like Figures 2 to 5 As shown, an iron sheet 8 is fixedly connected to the lower end of the storage box 7 near the frame 1, and a permanent magnet 9 is fixedly connected to the side wall of the frame 1. The iron sheet 8 and the permanent magnet 9 are attracted to each other.
[0029] Specifically, after the positioning block 6, which is fixed to the storage box 7, is fully inserted into the positioning groove 5, the iron piece 8 will align with the permanent magnet 9. At this time, the iron piece 8 will be attracted to the permanent magnet 9, thereby preventing the storage box 7 from moving upward on its own. In addition, the permanent magnet 9 can be made of neodymium iron boron material.
[0030] like Figure 3As shown, the storage box 7 and the positioning block 6 have through grooves inside, and the partition 3 has a cooling groove 11 inside, which is connected to the through groove.
[0031] Specifically, if the ambient temperature is high, fresh mushrooms are prone to spoilage. In this case, an ice box can be placed in the storage box 7. When the ice box melts, it will lower the temperature in the vicinity and generate cold air. This cold air will then enter the cold air trough 11 through the channel. This will not only lower the temperature inside the frame 1, but also prevent the fresh mushrooms from coming into direct contact with the ice box, thus avoiding frostbite, mechanical damage, metabolic disorders, and microbial contamination.
[0032] It is worth noting that: the bottom of frame 1 is fixedly connected to a ring-shaped bottom frame, the outer contour of which is equal to the inner contour of the top of frame 1, forming a nested fitting structure. When two frames 1 are stacked, the bottom frame of the upper frame 1 can fit precisely into the top opening of the lower frame 1. The outer periphery of the bottom frame and the inner edge of the top surface of the lower frame 1 form a gap fit or transition fit, which will not cause wobbling due to being too small, nor will it be unable to fit due to being too large, thus achieving a stable engagement. This allows the upper frame 1 to "sit" on the top surface of the lower frame 1 through the bottom frame and form a limit, preventing lateral displacement.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
