Description

Technical Field

[0001] The utility model relates to the technical field related to edible fungus breeding, and specifically is a device for breeding and improving new edible fungus varieties. Background Art

[0002] Edible fungi are large fungi that can be eaten by humans. Specifically, edible fungi are edible mushrooms. Mushrooms are large fungi that form large, fleshy fruiting bodies or sclerotia-like tissues and can be eaten or used medicinally. The breeding process for edible fungi involves three steps: first, preparing a spore suspension. Fresh, sterile spores of edible fungi are transferred into sterile saline or phosphate buffer and shaken to form a spore suspension. Second, mutagenesis treatment is performed using a mutagen, such as ultraviolet light, in a darkened chamber. Third, screening is performed. Mutagenesis only expands the range of variation but does not determine the direction of variation. Therefore, the greatest difficulty in mutagenesis is screening. Only by selecting the desired mutants from a large and diverse population of variants can the desired mutants be found.

[0003] The utility model patent with announcement number CN218851554U discloses a device for selecting and improving new varieties of edible fungi, which belongs to the technical field related to edible fungi breeding. It solves the problem that in the existing technology, the sterile spores of edible fungi are mainly shaken manually when shaking them. The manual shaking method has low mixing efficiency and a large workload for workers. When breeding a large number of edible fungi, the workers will work for a long time due to fatigue, which will lead to poor quality of shaking the sterile spores of edible fungi, thereby affecting the survival rate during subsequent mutagenesis treatment. The device includes a breeding box; a mixing component, the separated sides of the mixing component are fixedly connected to the two sides of the inner wall of the breeding box, and the mixing component includes two placement boxes, the separated sides of the two placement boxes are fixedly connected to the two sides of the inner wall of the breeding box, and the bottoms of the inner walls of the two placement boxes are fixedly connected to motors. The utility model provides a device for selecting and improving new varieties of edible fungi. The movement of the clamping screw drives the clamping plate to move downward, and the movement of the clamping plate drives the first rubber pad to move downward, thereby fixing the mixing tube. The rotation of the motor drives the clamping frame to rotate, thereby mixing the liquid in the mixing tube. The operation is simple and convenient, and the efficiency of shaking the sterile spores of edible fungi is effectively improved. The quality after shaking is better than that of manual shaking.

[0004] However, the above patent still has shortcomings: the patent mixes the liquid in the mixing tube by controlling the continuous rotation of the mixing tube, but since the liquid inside the mixing tube will move to both ends of the mixing tube due to inertia and centrifugal force while the mixing tube rotates, the liquid will remain stationary inside the mixing tube, resulting in poor mixing effect of the liquid in the mixing tube, affecting the survival rate of edible fungi.

At the same time, it drives the stirring barrel 3 and the first rotating shaft 19, and the first rotating shaft 19 drives the first bevel gear 20 to perform a circular motion with the fifth bevel gear 27 as the center. When the first bevel gear 20 rotates, it rotates by cooperation with the fifth bevel gear 27. While the device is stirring the sterile spores of edible fungi and sterile saline or phosphate buffer inside the stirring barrel 3, the stirring barrel 3 can be controlled to rotate, so that the sterile spores of edible fungi and sterile saline or phosphate buffer are continuously turned over inside the stirring barrel 3, thereby improving the mixing speed of the sterile spores of edible fungi and sterile saline or phosphate buffer, thereby improving work efficiency.

While the rotating frame 2 rotates, it drives the mixing barrel 3 and the first rotating shaft 19. The first rotating shaft 19 drives the first bevel gear 20 to rotate with the fifth bevel gear 27 as the center of the circle.

While stirring, the stirring barrel 3 is controlled to rotate, so that the sterile spores of edible fungi and sterile physiological saline or phosphate buffer are continuously turned over inside the stirring barrel 3, thereby improving the mixing speed of the sterile spores of edible fungi and sterile physiological saline or phosphate buffer, thereby improving work efficiency. The first bevel gear 20 rotates while driving the first rotating shaft 19, and the first rotating shaft 19 rotates inside the rotating frame 2 while driving the second synchronous wheel 18.

The flushing liquid is fully stirred and mixed, and the sterile spores of edible fungi and the sterile physiological saline or phosphate buffer solution in the stirring barrel 3 can be fully stirred and mixed, thereby improving the mixing effect of the sterile spores of edible fungi and the sterile physiological saline or phosphate buffer solution, and solving the problem that the existing device for selecting and improving new varieties of edible fungi mixes the liquid in the mixing tube by controlling the continuous rotation of the mixing tube, but since the liquid inside the mixing tube moves to the two ends of the mixing tube due to inertia and centrifugal force while the mixing tube rotates, the liquid remains stationary inside the mixing tube, resulting in poor mixing effect of the liquid in the mixing tube, thereby affecting the survival rate of the edible fungi.
