Description

Technical Field

[0001] This utility model relates to the field of edible fungi mutation breeding technology, specifically a soaking device for edible fungi mutation breeding. Background Technology

[0002] Derived from a large number of edible fungi in nature, useful strains are isolated and screened, then improved and stored for use in production. Originally referring to spores (equivalent to plant seeds), in actual production, the pure mycelium cultivated artificially, along with the culture medium, is often called a strain. When breeding existing edible fungi, it is necessary to use containers such as test tubes to soak the strains.

[0003] For example, the soaking device for edible fungus mutation breeding disclosed in authorization announcement number CN219861280U includes a topless box with a lid on top. A vibration frame is installed inside the box, and a test tube rack for storing test tubes is installed inside the vibration frame. A support rod is vertically fixed at the bottom of the vibration frame, and a vibration assembly for vibrating the vibration frame is installed inside the box below the support rod. The beneficial effects of this invention are as follows: by fixing test tubes containing edible fungus spores and physiological saline in the vibration frame using the test tube rack, the edible fungus spores and physiological saline in the test tubes are mixed evenly under the action of the vibration assembly, preventing edible fungus spores from adhering to the test tube walls and minimizing the uneven distribution of edible fungus spores on the surface and bottom of the physiological saline.

[0004] Although the aforementioned patent can mix edible fungal spores and physiological saline in test tubes evenly through vibration, the inner diameter of the slot on the vibration frame used to fit the test tubes is fixed, while the diameter of the test tubes varies. The fixed hole diameter cannot be compatible with test tubes of various sizes, and the test tubes shake and shift during vibration, affecting the mixing effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A soaking device for edible fungi mutation breeding includes a fixed frame 1. Several movable frames 2 are arranged side-by-side on the lower left side of the fixed frame 1. Rollers 3 are movably mounted on the upper ends of the movable frames 2 via rotating shafts. A width adjustment mechanism is provided between the fixed frame 1 and the movable frames 2. The width adjustment mechanism includes shaft brackets 7. Shaft brackets 7 are fixedly installed at both ends of the lower left side of the fixed frame 1. A lead screw 8 is movably mounted between the shaft brackets 7 via bearings. Several movable blocks 9 are threaded onto the external surface of the lead screw 8. The top ends of the movable blocks 9 are fixedly connected to the bottom end of the movable frames 2. A motor 2 10 is fixedly installed on the external surface of the right shaft bracket 7. The output shaft of the motor 2 10 is fixedly connected to the lead screw 8. Shaft brackets 2 11 are fixedly installed on both sides of the lower middle part of the fixed frame 1. Guide rods 12 are fixedly installed between the shaft brackets 2 11. A straight rod movably connected to the guide rods 12 is fixedly installed at the bottom end of the movable frames 2. A spool sleeve has a push plate 6 movably installed inside the right side of the fixed frame 1. An adjustment mechanism is provided on the left side of the push plate 6. The adjustment mechanism includes a second movable frame 16. The second movable frame 16 is movably installed on the left side of the push plate 6 and near the right end of the first movable frame 2. The upper end of the second movable frame 16 is movably installed with a second idler roller 17 via a rotating shaft. The third idler roller 18 is arranged side by side on the left side of the push plate 6 and near the right end of the second movable frame 16. The right end of the third idler roller 18 is movably connected to the push plate 6 via a rotating shaft. An electric push rod 19 is fixedly installed on the outer side of the middle right end of the fixed frame 1. The output shaft of the electric push rod 19 is fixedly connected to the middle right side of the push plate 6. Connecting rods 20 are fixedly installed at both ends of the bottom left side of the second movable frame 16. The other end of the connecting rod 20 is movably connected to the bottom end of the first movable frame 2. A spring 21 is movably installed between the first movable frame 2 and the second movable frame 16 and outside the connecting rod 20.

[0027] In this embodiment, the combined action of the lead screw 8 width adjustment mechanism and the electric push rod 19 length adjustment mechanism realizes the dual adaptive adjustment function of radial and axial directions, which can accurately control the roller spacing and automatically compensate for the test tube length tolerance. With the linkage design of the connecting rod 20 and the spring 21, it can stably clamp various test tubes of different diameters and lengths, solving the technical bottleneck of traditional devices being unable to be compatible with multiple specifications of test tubes.

[0028] like Figure 2 and Figure 4 As shown, drive rollers 4 are arranged side by side on the left side inside the fixed frame 1 and near the right end of the movable frame 2. A transmission housing 5 is fixedly installed on the outside of the left side of the fixed frame 1. A rotating mechanism is arranged between the drive rollers 4 and the transmission housing 5. The rotating mechanism includes a worm gear 13. The worm gear 13 is movably installed on the upper end inside the transmission housing 5. The left end of the drive roller 4 is movably connected to the fixed frame 1 through a rotating shaft. The left end of the rotating shaft passes through the fixed frame 1 and is fixedly installed with a worm wheel 14 that meshes with the worm gear 13. A motor 15 is fixedly installed on the outside of the right end of the transmission housing 5. The output shaft of the motor 15 is fixedly connected to the worm gear 13.

[0029] In this embodiment, a hybrid support structure combining active drive and three-point floating is adopted. The drive roller 4, driven by the worm gear 14 and worm 13, provides stable rotational power. Together with three sets of support rollers, it forms an adaptive floating support, so that the test tube rotation process is free from deviation, which significantly improves the mixing uniformity. It is particularly suitable for experimental scenarios with strict requirements for mixing uniformity, such as bacterial mutagenesis.

[0030] Working principle: During operation, the spacing of movable frame 12 is first adjusted according to the diameter of the test tube. Motor 210 is started to drive screw 8 to rotate, causing movable block 9 to move axially along screw 8. Synchronous displacement is achieved by sliding along guide rod 12 through the linear bushing at the bottom of movable frame 12. When screw 8 rotates clockwise, movable block 9 drives roller 3 to move away from drive roller 4 to increase the spacing. When it rotates counterclockwise, it moves towards drive roller 4 to decrease the spacing. At this time, through the elastic connection of connecting rod 20 and spring 21, movable frame 21 will adjust the spacing synchronously with the movement of movable frame 12. Then, electric actuator 19 pushes push plate 6 to the left, push plate 6 drives roller 318 to the left, together with roller 217 on movable frame 21, to support the right end of the test tube, while the left end of the test tube is supported by roller 3 and drive roller 4. The drive roller 4 rotates through the worm gear 14 and worm 13 mechanism, which drives the test tube to rotate under the combined action of the first roller 3, drive roller 4, second roller 17 and third roller 18. The rotation of the test tube makes the edible fungus spores inside fully mixed with the physiological saline.
