Description

Technical Field

[0001] The utility model relates to the technical field of edible mushroom culture media, and specifically, to a simple sterilization device for edible mushroom culture media. Background Art

[0002] Edible mushroom culture media are rich in nutrients such as carbon sources and nitrogen sources, and are extremely prone to breeding miscellaneous bacteria such as bacteria and molds. These miscellaneous bacteria will compete with the target bacteria for nutrients, resulting in the corruption of the culture media, and even producing toxins to inhibit the growth of edible mushrooms. Unsterilized culture media may contain wild mushroom spores or viruses (such as phages), which directly threaten the normal development of the mycelium, leading to the degradation of the strains or an increase in the contamination rate of the mushroom bags. Therefore, edible mushroom culture media need to be sterilized. By sterilization, the purity of the strains can be guaranteed and the storage period can be extended. The main methods of sterilization include moist heat sterilization, chemical sterilization, and irradiation sterilization, etc. Moist heat sterilization is mainly through steam sterilization. Although the sterilization effect can be achieved, it causes great damage to heat-sensitive components such as vitamins and amino acids. If sterilized by chemical methods, chemical sterilants are likely to remain in the edible mushrooms or the culture environment after sterilization, and are easily introduced into the human body through the food chain, resulting in chronic poisoning or immunosuppression. Therefore, the relatively simple and practical sterilization method is mainly irradiation sterilization. This kind of irradiation is mainly through light such as ultraviolet rays. For example, in the existing patented technology (publication number CN221653300U) that has been published, it discloses a sterilization box for edible mushroom culture media, which mainly aims to quickly sterilize the edible mushroom culture media by the ultraviolet rays generated by ultraviolet sterilization lamps. Another example is the patented technology of a simple sterilization device for edible mushroom culture media disclosed in publication number CN213526544U, which also uses ultraviolet sterilization lamp technology to achieve the sterilization of edible mushrooms. This sterilization method can reduce the damage to edible mushrooms and chemical residues, but the common defect of this sterilization method is that the irradiation of the ultraviolet sterilization lamp on the edible mushroom culture media is uneven, resulting in a poor sterilization effect. Summary of the Utility Model

[0012] In order to facilitate the better rotation of the culture dish in the placement hole, a plurality of guide wheels are circumferentially arranged in the placement hole, and the guide wheels are connected to the inner wall of the placement hole through brackets.

[0013] In order to improve the stability of the lifting table during the lifting process, it further includes an auxiliary shaft.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] In the utility model, the rotating mechanism can be rotated by the driving component, thereby driving the rotating table to rotate. The rotating table is provided with a plurality of placement holes, and a plurality of culture dishes can be placed at the same time. The culture dishes can be placed through the placement holes by the bracket, so that the bottom of the culture can also be irradiated by the ultraviolet sterilization lamp. By the self-rotation mechanism, when the rotating table rotates relative to the lifting table, the support rods in each bracket can be rotated, wherein the support rods are used to support the culture dishes, and the tops of the support rods are provided with anti-slip rubber heads. When the support rods rotate, the culture dishes can be driven to rotate inside the placement holes. Therefore, the plurality of culture dishes can not only rotate with the rotating table, but also rotate by themselves inside the placement holes, thereby enhancing the irradiation uniformity between the culture dishes and the ultraviolet sterilization lamp, and improving the sterilization effect.

[0017] In the utility model, multiple ultraviolet sterilization lamps arranged by surrounding supports can be surrounded by the driving component under the action of the driving component, so that the multiple ultraviolet sterilization lamps surround the outer side of the rotating turntable, which can enhance the sterilization effect.

When the turntable is rotatably connected with the lifting member, while ensuring the rotation of the turntable, it can also drive the lifting action of the turntable at the same time, thereby driving the culture dish to rotate with the turntable and to rotate by itself, and to perform lifting and lowering actions at the same time. In conjunction with the multiple ultraviolet sterilization lamps that continuously rotate around the turntable, the uniform illumination effect of the ultraviolet sterilization lamp on the edible fungus culture medium is further enhanced, so that the culture dish is irradiated by the ultraviolet sterilization lamp with basically no dead angles. Compared with the prior art, the uniform illumination of the ultraviolet sterilization lamp on the edible fungus culture medium is significantly enhanced, and the sterilization effect is enhanced.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Such as Figures 1 to 9As shown in the figure, this embodiment proposes a simple sterilization device for edible mushroom culture media, which includes a sterilization box body 1 with an operation opening on the front side. It also includes a support plate 2, a lifting member, a rotating table 3, placing holes, a bracket 4, a self-rotation mechanism, ultraviolet sterilization lamps 5 and a driving assembly. The support plate 2 is fixedly installed inside the sterilization box body 1, and a rotating mechanism is provided on the support plate 2. The lifting member is arranged on the rotating mechanism, and a lifting platform 6 is installed at the top of the lifting member. The rotating table 3 is rotatably arranged above the lifting platform 6 through the rotating mechanism. A plurality of placing holes are provided on the rotating table 3. The bracket 4 is installed on the lower side of the placing hole, and a support rod 31 is rotatably installed in the middle. The self-rotation mechanism is arranged between the support rod 31 and the lifting platform 6 and is used to drive the support rod 31 to rotate self when the rotating table 3 rotates circumferentially. A plurality of ultraviolet sterilization lamps 5 are provided and are arranged in a surrounding manner around the rotating table 3 through a support structure. The driving assembly is installed on the sterilization box body 1 and is used to drive the support structure and the rotating mechanism to act, so that while the ultraviolet sterilization lamps 5 rotate around the rotating table 3, the rotating table 3 is driven to rotate and lift.

[0031] As Figure 1 shown, correspondingly, a transparent cover 7 is rotatably installed on the operation opening, and the lower side of the transparent cover 7 is detachably connected to the side wall of the sterilization box body 1 through a bolt rod with a handwheel. An opening is provided at the top of the sterilization box body 1, and a cover plate 8 is provided on the opening. The cover plate 8 is detachably connected to the sterilization box body 1 through bolts. The internal situation of the sterilization box body 1 can be observed through the transparent cover 7. The transparent cover 7 can be locked and opened conveniently through bolts. The cover plate 8 installed through bolts at the top facilitates the maintenance and cleaning of the inside of the sterilization box body 1. Sealing rings are provided on the inner walls of both the transparent cover 7 and the cover plate 8 to ensure the sealing performance during use.

[0032] As Figure 4 shown, in this embodiment, the rotating mechanism includes a lifting cylinder 9, a worm gear 10 and a lifting rod 11. The lifting cylinder 9 is rotatably installed in the middle of the support plate 2. The worm gear 10 is located above the support plate 2 and is fixedly sleeved outside the lifting cylinder 9. The lifting rod 11 is hexagonal and is longitudinally slidably arranged in the lifting cylinder 9. The top of the lifting rod 11 is connected to the center of the bottom end of the rotating table 3 through a round shaft 12. A worm 32 is rotatably arranged on one side of the worm gear 10 and meshes with the worm gear 10. The worm 32 is driven to rotate by the driving assembly, and the worm 32 drives the worm gear 10 to rotate, thereby driving the lifting cylinder 9 to rotate. Through the cooperation between the lifting rod 11 and the lifting cylinder 9, the lifting rod 11 can be driven to rotate and the longitudinal sliding between the lifting rod 11 and the lifting cylinder 9 can be realized.

[0033] As Figures 3 to 4As shown in the figure, in this embodiment, the lifting member includes a bidirectional screw 13, a moving block 14, and a support rod 15. Both ends of the worm 32 are coaxially connected with a bidirectional screw 13. The bidirectional screw 13 is symmetrically screwed with a moving block 14. The top end of each moving block 14 is rotatably installed with a support rod 15. And the other ends of the two support rods 15 are rotatably connected to the bottom end of the lifting table 6 through a rotating seat 16. When the worm 32 rotates, it can drive the bidirectional screw 13 to rotate. Therefore, the two moving blocks 14 symmetrically arranged on the bidirectional screw 13 can be close to or away from each other, so that the inclination angles of the two rotatably connected support rods 15 change, realizing the support and change of the height of the lifting table 6. In order to improve the sliding stability of the moving block 14 on the support plate 2, the moving block 14 is T-shaped, and a T-shaped chute 17 for the moving block 14 to slide is provided on the support plate 2. The moving block 14 is slidably arranged in the T-shaped chute 17.

[0034] As Figures 2 to 3 shown, in this embodiment, the support structure includes a first gear 18, a toothed belt 19, and a synchronous shaft 20. Four first gears 18 are rotatably installed in a rectangular shape on both inner walls of the sterilization chamber body 1. The four first gears 18 on the same side are sleeved with a toothed belt 19. A synchronous shaft 20 is concentrically connected between two horizontally opposite first gears 18. Through the synchronous shaft 20, it can be ensured that the two horizontally opposite first gears 18 rotate simultaneously. Through the sleeving of the toothed belt 19, it can be ensured that the four first gears 18 on the same side in the longitudinal direction rotate synchronously. Therefore, when one of the first gears 18 rotates, multiple first gears 18, that is, the two toothed belts 19 can rotate simultaneously. It also includes a mounting plate and a mounting seat. There are multiple mounting plates, and they are vertically installed between the two toothed belts 19. The mounting plate is connected to the outer wall of the toothed belt 19 through the mounting seat. The ultraviolet sterilization lamp 5 is installed on the inner wall of the mounting plate close to the rotating table 3. Through the mounting plate, the two toothed belts 19 can be connected to ensure their synchronous effect, and it can also provide installation support for the ultraviolet sterilization lamp 5. Among them, the toothed belt 19 is in a taut state after installation and debugging to ensure effective transmission.

[0035] As Figures 3 to 4As shown in the figure, in this embodiment, the rotation mechanism includes an annular groove 21, a toothed ring 22, and a second gear 23. A plurality of annular grooves 21 are concentrically arranged at the top end of the lifting platform 6. A toothed ring 22 is fixedly connected to the outer side wall of each annular groove 21. The second gear 23 is coaxially installed at the bottom end of the support rod 31 and extends into the annular groove 21 at the corresponding position to mesh with the toothed ring 22. The round shaft 12 penetrates through the center of the lifting platform 6 and is rotatably connected to the lifting platform 6. Since the lifting platform 6 and the rotating platform 3 are rotatably connected through the round shaft 12, the distance between the rotating platform 3 and the lifting platform 6 remains unchanged. However, since the rotating platform 3 only makes a lifting motion under the action of the lifting member, a relative rotation motion occurs between the rotating platform 3 and the lifting platform 6. The lifting platform 6 is circularly arranged. When the support rod 31 rotates around the annular groove 21, when the second gear 23 meshes with the toothed ring 22, it will drive the support rod 31 to rotate on the bracket 4. An anti-slip rubber head is provided at the top of the support rod 31, and the weight of the culture dish falls on the anti-slip rubber head at the top of the support rod 31. Therefore, it can drive the culture dish to rotate around the round shaft 12 as the center of the circle with the rotating platform 3 and can also rotate by itself in the placement hole, improving the uniformity of the irradiation contact with the ultraviolet sterilization lamp 5. In order to facilitate the better rotation of the culture dish in the placement hole, a plurality of guide wheels 24 are circumferentially arranged in the placement hole, and the guide wheels 24 are connected to the inner wall of the placement hole through brackets.

[0036] As Figures 1 to 3 shown in the figure, in this embodiment, the drive assembly includes a motor 25, a first pulley 26, a second pulley 27, and a timing belt 28. The motor 25 is fixedly installed on the outer side wall of the sterilization box body 1, and the output shaft penetrates through the outer side wall of the sterilization box body 1 and is coaxially connected to one of the first gears 18. A first pulley 26 is sleeved on the synchronous shaft 20 coaxially arranged with the output shaft of the motor 25. A second pulley 27 is sleeved on the bidirectional screw 13, and one end of the bidirectional screw 13 far from the worm gear 10 is rotatably connected to the inner wall of the sterilization box body 1. By rotating the motor 25, the first gear 18 can be driven to rotate, and thus, under the action of the support structure, the synchronous shaft 20 can be driven to rotate. Under the transmission cooperation of the first pulley 26, the second pulley 27, and the timing belt 28, the worm 32 can be rotated, thereby realizing the drive of the worm gear 10 and the rotation drive of the bidirectional screw 13.

[0037] It should be noted that since cables are connected to each of the ultraviolet sterilization lamps 5, in order to ensure that the cables do not get entangled, the motor 25 is set to rotate forward and backward. That is, after the support structure drives the multiple ultraviolet sterilization lamps 5 to rotate around the turntable 3 for one circle, it rotates backward, and then rotates forward again after rotating backward for one circle, and this cycle continues. The forward and backward rotation setting of the motor 25 belongs to a connection method well-known to those skilled in the art. It can be electrically installed by referring to the forward and backward rotation circuit in the specification, or a forward and backward rotation switch can be installed for manual control of its forward and backward rotation, which will not be elaborated here. Spaces for placing the cables of the ultraviolet sterilization lamps 5 are left on both sides inside the sterilization chamber body 1, and the cables of the ultraviolet sterilization lamps 5 are reserved with sufficient length for their use. Moreover, the bidirectional screws 13 used in this embodiment are all standard parts with high precision and no machining errors. After installation, the use angles and positions of the four bidirectional screws 13 are adjusted to be consistent.

[0038] As Figures 3 to 4 shown, in order to improve the stability of the lifting platform 6 during the lifting process, an auxiliary shaft 29 is further included. The auxiliary shaft 29 is arranged on the other side of the worm gear 10 and is set to be in parallel synchronous transmission with the worm gear 10 through a belt 33. Belt pulleys 30 are sleeved on the two parallel bidirectional screws 13, and a belt 33 is sleeved between the two belt pulleys 30 to ensure their synchronous rotation. After the belt 33 is installed and adjusted, it is in a taut state to ensure effective transmission. Both ends of the auxiliary shaft 29 are also coaxially connected with bidirectional screws 13, and the other ends of the bidirectional screws 13 are rotatably connected to the inner wall of the sterilization chamber body 1. Movable blocks 14 are symmetrically screwed on the two bidirectional screws 13 located on the auxiliary shaft. The top of each movable block 14 is also rotatably installed with a support rod 15, and the other ends of the two support rods 15 are also rotatably connected to the bottom end of the lifting platform 6 through a rotating seat 16.

[0039] When the simple sterilization device for edible mushroom culture medium is in use, first open the transparent cover 7, place the petri dishes to be sterilized one by one in a plurality of placement holes, then close the transparent cover 7 and rotate the bolt to lock it. After locking, start the motor 25. The motor 25 rotates, driving the first gear 18 to rotate, so that a plurality of ultraviolet sterilization lamps 5 rotate around the rotating table 3. At the same time, when the synchronous shaft 20 rotates, it drives the worm 32 and the bidirectional screw 13 to rotate. The bidirectional screw 13 rotates, which can drive two opposite moving blocks 14 on it to approach or move away from each other, thereby driving the lifting platform 6 to rise or fall, that is, driving the petri dishes on the rotating table 3 to rise or fall under the surrounding irradiation of a plurality of ultraviolet sterilization lamps 5. Due to the meshing of the worm 32 and the worm wheel 10, the rotation of the worm 32 will also drive the worm wheel 10 to rotate, so that it drives the rotating table 3 to rotate through the lifting rod 11 and the round shaft 12. When the rotating table 3 rotates, the second gear 23 on the support rod 31 meshes with the toothed ring 22, realizing the self-rotation of the support rod 31, that is, driving the petri dishes to rotate under the surrounding irradiation of a plurality of ultraviolet sterilization lamps 5. As the rotating table 3 rotates around the round shaft 12 as the center and continuously rises and falls, the uniform irradiation and sterilization of the petri dishes by a plurality of ultraviolet sterilization lamps 5 can be achieved.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
