Description

Technical Field

[0001] This utility model relates to the field of edible fungi cultivation tools, specifically to an edible fungi inoculation device. Background Technology

[0002] In large-scale edible mushroom production and scientific research, inoculation is the core link connecting strain propagation and culture medium colonization. It directly determines the mycelial germination efficiency, contamination rate control, and final fruiting quality. The standardization of operation and the suitability of tools have a significant impact on the economic benefits of the entire production chain. As the core tool in this step, the inoculation needle's main function is to accurately cut active mycelial blocks from the mother culture medium, such as slant test tubes or agar plates, and transplant them intact into the original or cultivated culture medium to ensure the genetic stability and activity of the strain. Currently, the inoculation needles widely used in the industry are mainly divided into two categories: one is the traditional metal needle, mostly made of stainless steel wire with a diameter of 0.5-1mm, which can only pick up mycelia and cannot independently cut them; the other is the simple shovel-shaped inoculation needle, which has a small shovel head welded or ground at the end of the metal needle. Although it has basic cutting capabilities, its structural design remains at the "single-function" level and cannot meet the multiple requirements of efficiency, precision, and asepticity for modern inoculation.

[0003] Existing technologies suffer from the following drawbacks: Limited functionality and cumbersome operation: Traditional needle-shaped inoculation needles cannot directly cut the spawn; they require the use of a scalpel or another inoculation spatula. Cutting the spawn necessitates first using a scalpel to separate mycelial blocks from the mother culture, then using the inoculation needle to pick them up and transfer them. This multi-step process increases the risk of contamination, and frequent tool switching can lead to operator fatigue. Uneven spawn size: Relying on manual cutting with a spatula makes it difficult to precisely control the size and shape of the mycelial blocks, resulting in inconsistent inoculation amounts and affecting the subsequent mycelial growth rate and the uniformity of fruiting. Instability: When cutting the spawn, especially from a slanted mother culture, the mycelial blocks are prone to slipping, leading to cutting failure or fragmentation. This requires recutting, wasting mother culture resources and damaging the integrity of the mother culture medium, affecting the continued use of the mother culture. Susceptibility to contamination during storage: After use, the inoculation needle is directly exposed to air, making the needle tip susceptible to contamination. Thorough disinfection is required before the next use, which is time-consuming and labor-intensive. Therefore, developing an edible fungus inoculator that integrates quantitative cutting, stable seed collection, and convenient disinfection and storage is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an edible fungi inoculation device that is simple in structure, easy to operate, and capable of cutting and firmly extracting seeds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An edible fungus inoculation device includes a needle rod, a handle, a cutting part, and a positioning blade. The upper end of the needle rod is connected to the lower end of the handle. The lower end of the needle rod is provided with a cutting part, which is a hollow annular or U-shaped structure with an open side. The inner edge of the lower end of the cutting part is a sharp cutting blade for cutting fungal spawn. A positioning blade is provided on the inner wall of the cutting part from the open side inward for fixing the fungal spawn cut by the cutting part.

[0006] Furthermore, the positioning blade is a spiral positioning blade.

[0007] Furthermore, the positioning blade, which is narrow at the bottom and wide at the top, extends inward and upward from the lower end of the opening side.

[0008] Furthermore, the handle is hollow inside to house the needle bar and cutting part, and the top of the handle is provided with an openable and closable sealing cover.

[0009] Furthermore, a seed pressing rod is provided inside the lower end of the needle bar, and a clamping plate is provided on the upper part of the seed pressing rod. A corresponding clamping groove is provided on the needle bar to restrict the movement of the clamping plate.

[0010] Furthermore, the top of the needle bar has an inwardly recessed groove to facilitate the removal of the needle bar.

[0011] Furthermore, the cutting part and the needle bar are detachably connected, specifically by a threaded connection or a snap-fit ​​connection.

[0012] Furthermore, the outer surface of the handle is textured with anti-slip patterns.

[0013] Furthermore, a wad of disinfectant cotton is placed inside the handle.

[0014] The beneficial effects of this utility model are as follows: Compared with existing technologies, this invention has the following significant inventive advantages: The cutting section design combines the "cutting" and "picking" actions into one, eliminating the need to change tools, greatly improving work efficiency, and ensuring that the size and shape of the inoculated mycelium blocks are consistent each time, laying the foundation for uniform mycelial growth. The spiral positioning blade design effectively solves the problem of mycelium block slippage during cutting, improving the success rate and accuracy of cutting. The combination of the hollow handle and the sterile cotton ball provides the inoculator with a movable and continuously sterilized "sheath," which not only greatly reduces the risk of contamination during operation but also simplifies the preparation process before use. The detachable cutting section design allows a set of tools to meet diverse experimental and production needs by changing cutting heads of different diameters or shapes, improving the versatility and economy of the tool.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-7As shown, an edible fungus inoculation device includes a needle rod 1, a handle 2, a cutting part 3, a positioning blade 4, and a sealing cap 5. The edible fungus inoculation device is made of stainless steel. The lower end of the needle rod 1 is provided with threads or a snap fastener. The lower end of the needle rod 1 is movably connected to the cutting part 3 through threads or a snap fastener. The upper part of the cutting part 3 is correspondingly provided with threads or a groove. The cutting part 3 is a hollow annular or U-shaped structure with an open side 31 at the lower part. The inner edge of the lower end of the cutting part 3 is ground into a sharp cutting blade 32 for cutting the fungal spawn. The inner wall of the cutting part 3 is provided with a spiral positioning blade 4. The positioning blade 4 is narrow at the bottom and wide at the top, starting from the lower end of the open side 31 and extending inward and upward, for fixing the fungal spawn cut by the cutting part 3, so that the cut fungal spawn is not easy to slip off. The upper end of the needle rod 1 is movably connected to the lower end of the handle 2 through threads or a snap fastener. The handle 2 is a hollow cylinder used to store the needle bar 1 and the cutting part 3. The outer surface of the handle 2 is provided with anti-slip texture 21. The upper opening of the handle 2 is provided with a sealing cap 5, which is connected to the handle 2 by a snap or thread. The handle 2 also contains a cotton ball 7 soaked in 75% alcohol to provide a space for continuous disinfection of the needle bar 1 and the cutting part 3. The top of the needle bar 1 is provided with an inward recessed groove 12 for easy removal of the needle bar 1. The lower end of the needle bar 1 is provided with a pressing rod 6, which is a cylindrical structure used to press the inoculum cut by the cutting part 3 into the mushroom bag or culture medium. The upper part of the pressing rod 6 is provided with a retaining plate 61, and the needle bar 1 is provided with a corresponding retaining groove 11. The retaining groove 11 is an inverted L-shaped structure used to limit the range of motion of the retaining plate 61, thereby adjusting the position of the pressing rod 6.

[0025] In use, open the sealing cover 5 on the upper part of the handle 2, take out the needle rod 1 and the cutting part 3, then close the sealing cover 5 again, assemble the handle 2, needle rod 1 and cutting part 3, and insert the clamping plate 61 on the pressing rod 6 inside the lower end of the needle rod 1 into the horizontal groove of the clamping slot 11. Since the needle rod 1 and the cutting part 3 are always in an alcohol vapor environment, they can be used directly without re-firing, thus avoiding carbonization and contamination of the inoculum. The operator holds handle 2, aligns the cutting part 3 with the edge of a well-grown mother culture colony, presses down and rotates. The positioning blade 4, designed with a narrow bottom and wide top spiral structure, gradually rotates into the mycelium of the culture as the inoculum is rotated, securing the culture and preventing slippage. The sharp cutting blade 32 neatly cuts a ring-shaped or U-shaped mycelial block. Due to the presence of the open side 31, the mycelial block is not completely enclosed within the ring, facilitating observation and subsequent operations. Then, the inoculum carrying the standard mycelial block is moved to a test tube or bag containing new culture medium. The clamping plate 61 on the pressing rod 6 inside the lower end of the needle bar 1 slides from the horizontal groove of the clamping slot 11 into the vertical groove, causing the pressing rod 6 to move downwards and press the mycelial block into the inoculation hole of the culture medium. The inoculum is then withdrawn, leaving the mycelial block. After use, the needle bar 1 and cutting part 3 are returned to handle 2, and the sealing cap 5 is tightened. In actual production use, the cutting part 3 of different specifications or shapes can be replaced according to the size of the required bacterial block, so that the inoculator can be universal.
