Description

Technical Field

[0001] This utility model relates to the field of edible fungus cultivation technology, specifically to an oxygenation device for auricularia auricula cultivation bags. Background Technology

[0002] Golden ear fungus is a rare fungus used in both medicine and food. It has effects such as regulating immunity, protecting the liver, moisturizing the lungs and relieving cough, and beautifying the skin. Its host, *Trichoderma harzianum*, grows rapidly and has a high respiration rate, requiring more oxygen than common edible fungi. Currently, common methods for aerating and oxygenating mushroom bags during cultivation include: the breathable plug method (using breathable material to seal the end of the bag), the ring method (using ready-made or self-made rings to seal the bag), the venting hole method (making small holes or puncturing the bag at the edge of the colony after inoculation when it reaches a certain size), and the venting hole method (inserting small sticks into the substrate, which are then removed during inoculation to create venting holes). Among these, the venting hole method requires less material and has simpler operation, making it a frequently used method for aeration and oxygenation in existing technologies. Chinese patent document CN208691920U discloses an adjustable five-hole puncher for edible fungus culture media. This puncher has the advantages of a large number of holes, adjustable punching depth, and less material carried over after punching. It can perform multi-hole punching and aeration on edible fungus culture media, increasing the air exchange rate of the culture media, which is more conducive to mycelial growth and development, saving labor, shortening the mycelial growth cycle, reducing production costs, and improving production efficiency. Moreover, the five punching rods can be adjusted according to the length of the plastic bag, which is conducive to more concentrated and uniform mycelial growth. However, compared with ordinary edible fungi, golden ear fungus has a higher oxygen requirement. Relying on only five small holes will affect the growth and development of golden ear fungus to some extent, resulting in poor oxygenation. At the same time, the cultivation bags of golden ear fungus are usually long and narrow. The small holes made by the above-mentioned five-hole puncher are too concentrated, which can easily lead to uneven oxygenation and aeration, resulting in uneven growth and development of golden ear fungus in the cultivation bag (i.e., poor consistency of golden ear fungus in the same cultivation bag). Punching holes in different locations multiple times increases punching time and reduces punching efficiency. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an oxygenation device for auricularia auricula cultivation bags. This oxygenation device can prepare multiple small holes at different positions in a long strip-shaped auricularia auricula cultivation bag at one time, improving the uniformity and quantity of perforation and ensuring the uniformity and effect of aeration and oxygenation of auricularia auricula. At the same time, the oxygenation device can be easily disassembled and assembled, improving the efficiency and practicality of perforation and oxygenation.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An oxygenation device for auricularia auricula cultivation bags includes a lifting base, mounting blocks, and a perforation assembly. Three mounting blocks are sequentially engaged with the bottom of the lifting base along its length. The perforation assembly, corresponding to the mounting blocks, includes an outer shell, a sliding plate, a telescopic rod, a return spring, and perforation needles. The outer shell has a convex cross-section with external threads on its protruding outer wall. The sliding plate is slidably engaged within the inner cavity of the large-diameter section of the outer shell, and five perforation needles are evenly distributed on the bottom surface of the sliding plate. The end of each perforation needle, away from the sliding plate, penetrates the corresponding bottom surface of the outer shell. A coaxial telescopic rod (rotatably connected to the sliding plate) is positioned at the top of the sliding plate, and a through hole is opened at the protruding part of the outer shell corresponding to the telescopic rod. The sliding plate and the top surface of the inner cavity of the outer shell, located on the outer ring of the telescopic rod, are connected by a return spring. A threaded groove is opened at the bottom of the mounting block corresponding to the protruding part of the outer shell, and a top rod is positioned at the upper end of the threaded groove corresponding to the telescopic rod.

[0006] Based on further optimization of the above scheme, sliding lugs are respectively provided on both sides of the lifting seat, and support columns are provided on the perforated operating table corresponding to the sliding lugs. The sliding lugs are respectively slidably sleeved on the outer wall of the corresponding support columns. The bottom surface of the support columns is installed on the operating table through a fixed seat, and a compression spring is provided between the fixed seat and the sliding lug and on the outer wall of the support column.

[0007] Based on further optimization of the above scheme, a positioning nut is provided at the top of the support column, and the inner wall of the positioning nut is threadedly connected to the outer wall of the corresponding support column.

[0008] Based on the further optimization of the above scheme, a spline groove is opened on the top surface of the telescopic rod, and a snap-fit ​​block is set at the bottom of the top rod corresponding to the spline groove. The connection between the telescopic rod and the top rod is achieved by snapping the snap-fit ​​block into the spline groove.

[0009] Based on further optimization of the above scheme, the distance between the tips of adjacent punching pins on the bottom surface of the sliding plate is 0.3cm, the maximum diameter of the bottom of the outer shell is 5cm, and the maximum length of the punching pin protruding from the bottom surface of the outer shell is 3cm.

[0010] Based on further optimization of the above scheme, the threaded groove is a stepped groove with a small upper diameter and a large lower diameter, and the top rod is fixedly set on the top surface of the small diameter section.

[0011] The following are the technical effects of this utility model:

[0012] This invention, through the arrangement of a lifting seat, mounting block, and punching assembly, enables the preparation of five small holes at three locations on the golden ear mushroom cultivation bag in a single control process—that is, during one lifting and lowering of the lifting seat. This not only effectively ensures the uniformity of the punching positions, avoiding the uneven oxygenation problem of some areas being punched for aeration while others are not, but also improves the efficiency of punching and aeration, saving punching time. After using this aeration device, the ear base recovers quickly, grows significantly after 25 days, and can open and produce mushrooms, with good ear base uniformity and an opening rate of over 99%.

[0013] Furthermore, the punching assembly of this utility model, consisting of a housing, a sliding plate, a telescopic rod, a return spring, and a punching needle, not only facilitates the disassembly and replacement of the punching assembly through a threaded connection, but also allows the punching needle to retract into the inner cavity of the housing after the punching assembly is removed, making it easy to store and process. This prevents the needle tip from protruding when not in use and scratching the human body, and also effectively protects the punching needle from breaking during storage or transportation.

Detailed Implementation

[0021] 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.

[0022] Example 1:

[0023] An oxygenation device for auricularia auricula-judae cultivation bags includes a lifting base 10, mounting blocks 20, and a perforation assembly. There are three mounting blocks 20, which are sequentially engaged with the bottom of the lifting base 10 along its length (e.g., ...). Figure 2 (As shown); the drilling assembly is set corresponding to the mounting block 20, including a housing 31, a sliding plate 32, a telescopic rod 33, a return spring 34, and a drilling pin 35. The longitudinal section of the housing 31 is a convex-shaped structure, and its (upper) protruding part has external threads on its outer wall (combined with...). Figure 1 and Figure 4 As shown), the sliding plate 32 is slidably engaged in the inner cavity of the large-diameter section of the outer shell 31, and five perforating pins 35 are evenly distributed on the bottom surface of the sliding plate 32 (see...). Figure 1 As shown), the end of the punch 35 furthest from the sliding plate 32 penetrates the bottom surface of the corresponding outer casing 31 (as shown). Figure 4 As shown, five through holes are opened on the bottom surface of the outer shell 31 corresponding to the perforating pins 35. The distance between the tips of adjacent perforating pins on the bottom surface of the sliding plate 32 is 0.3cm. The maximum diameter of the bottom of the outer shell 31 is 5cm, and the maximum length of the perforating pins 35 protruding from the bottom surface of the outer shell 31 is 3cm (the protruding length is set according to the actual situation). A coaxial telescopic rod 33 is provided on the top of the sliding plate 32 (that is, the telescopic rod 33 and the sliding plate 32 are coaxial, and the telescopic rod 33 and the sliding plate 32 are rotatably connected). The protruding part of the outer shell 31 has a through hole corresponding to the telescopic rod 33 (the outer diameter of the telescopic rod 33 is smaller than the inner diameter of the through hole, and the top of the telescopic rod 33 can protrude from the top of the through hole). The sliding plate 32 and the top surface of the inner cavity of the outer shell 31 are connected by a return spring 34 on the outer ring of the telescopic rod 33 (e.g., Figure 4 (As shown); a threaded groove 21 is formed on the bottom of the mounting block 20 corresponding to the protrusion of the outer shell 31, and a top rod 22 is provided at the upper end of the threaded groove 21 corresponding to the telescopic rod 33. A spline groove is formed on the top surface of the telescopic rod 33, and a snap-fit ​​block is provided at the bottom of the top rod 22 corresponding to the spline groove. The connection between the telescopic rod 33 and the top rod 22 is achieved by snapping the snap-fit ​​block into the spline groove (as shown). Figure 4 As shown); the threaded groove 21 is a stepped groove with a smaller upper diameter and a larger lower diameter (see...). Figure 4 As shown), and the top rod 22 is fixedly installed on the top surface of the small diameter section (the top surface of the outer shell 31 is limited by the stepped transition of the threaded groove 21, as shown). Figure 4 (As shown).

[0024] Sliding lugs 11 are provided on both sides of the lifting seat 10 (e.g. Figure 2 or Figure 3 As shown), a support column 40 is provided on the drilling worktable corresponding to the sliding lug 11. The sliding lug 11 is slidably sleeved on the outer wall of the corresponding support column 40. The bottom surface of the support column 40 is installed on the worktable through a fixing seat 41 (screw holes can be evenly opened on the fixing seat 41, and the fixing and positioning between the fixing seat 41 and the worktable is realized through the screw holes and positioning bolts. The specific fixing method is set according to the actual situation. In this embodiment, it is not limited in many ways, and those skilled in the art can understand it). A compression spring 42 is provided between the fixing seat 41 and the sliding lug 11 and on the outer wall of the support column 40 (e.g., Figure 2 As shown, the bottom end of the compression spring 42 is fixedly connected to the top surface of the fixed base 41, and the top end of the compression spring 42 is in contact with the bottom surface of the sliding lug 11. A positioning nut 43 is provided on the top of the support column 40, and the inner wall of the positioning nut 43 is threadedly connected to the outer wall of the corresponding support column 40.

[0025] Working principle:

[0026] In use, first fix the support column 40 to the operating table through the connection between the fixing seat 41 and the operating table (ensure that the distance between the two support columns 40 is greater than the length of the golden ear cultivation bag); then, tighten the positioning nut 43 to disengage it from the corresponding support column 40, and attach the sliding lugs 11 at both ends of the lifting seat 10 to the outer wall of the support column 40, ensuring that the bottom surface of the sliding lug 11 contacts the top of the corresponding compression spring 42, and then tighten the positioning nut 43 on the top of the support column 40 (to prevent the sliding lug 11 from disengaging from the support column 40).

[0027] Next, a drilling assembly is installed on the bottom surface of each mounting block 20. Specifically, the spline groove of the telescopic rod 33 is aligned with the snap-fit ​​block of the top rod 22 (ensuring that the snap-fit ​​block is snapped into the spline groove). At the same time, the threaded section of the protruding part of the outer shell 31 is aligned with the large diameter end of the threaded groove 21. The outer shell 31 is screwed on so that it moves upward along the threaded groove 21. At this time, the top rod 22 pushes against the telescopic rod 33, causing it to move downward relative to the outer shell 31. This pushes the sliding plate 32 downward in the inner cavity of the outer shell 31, causing the drilling needle 35 to protrude from the bottom surface of the outer shell 31, thus realizing the installation of the drilling assembly.

[0028] Finally, move the golden ear cultivation bag to the lower side of the lifting seat 10 (the golden ear cultivation bag can be moved by a conveyor belt or by manual handling, the specific form is set according to the actual situation, and no restrictions are made in this embodiment), press the top of the lifting seat 10, and move it down along the axis of the support column 40 (the compression spring 42 is further compressed), thereby completing the punching of the cultivation bag (after punching, release the lifting seat 10, and due to the elastic force of the compression spring 42, the lifting seat 10 moves up and resets; a rubber buffer pad can be set on the bottom surface of the positioning nut 43 to complete the elastic buffer during the upward movement of the lifting seat 10; at the same time, a rubber buffer pad can also be set on the top surface of the sliding support ear 11 to further achieve buffering).

[0029] Example 2:

[0030] As another preferred embodiment of this utility model, in order to achieve adjustment of the distance between the mounting blocks 20 and thus make openings at different positions on the cultivation bag to improve the practicality of the aeration device, based on the above embodiment 1, three horizontal grooves 12 are evenly opened on the bottom surface of the lifting seat 10 along its length (e.g., Figure 3 , Figure 5 As shown), the top of the mounting block 20 is slidably engaged within the horizontal groove 12; one side of the mounting block 20 (i.e. Figure 3 The back side shown Figure 5 A positioning groove is formed in the middle of the top surface shown. A plurality of positioning holes are evenly arranged on the sidewalls of the horizontal groove 12 corresponding to the positioning groove (the positioning holes are evenly distributed along the length of the horizontal groove 12, such as...). Figure 5 As shown), the sliding limit of the mounting block 20 is achieved by sequentially inserting positioning pins into the positioning holes and corresponding positioning slots (as shown). Figure 5 (As shown).

[0031] Example 3:

[0032] As another preferred embodiment of this utility model, to prevent residue from the substrate bag from adhering to the outer wall of the punching needle 35 after punching and affecting the next punching, based on the above embodiment 1, a guide plate is provided on the end face of the two fixed seats 41 and between the two sets of compression springs 42. The guide plate is correspondingly provided with the lifting seat 10 (i.e., the width of the guide plate is the same as the width of the lifting seat 10), and the guide plate has a guide hole corresponding to the punching needle 35 (e.g., Figure 6 As shown), the diameter of the guide hole is slightly larger than the maximum outer diameter of the punch 35; the thickness of the guide plate is 1-2 cm (corresponding to the maximum length of the punch 35 protruding from the bottom surface of the outer shell 31 increased by 1-2 cm, i.e., 4-5 cm).
