Description

Technical Field

[0001] This utility model relates to the field of culture medium sterilization technology, specifically to an ultraviolet sterilization box for edible fungi culture medium. Background Technology

[0002] Edible mushroom culture medium, also known as culture substrate or culture medium, is a matrix that provides the nutrients, moisture, and pH required for the growth and development of edible fungi. Culture media used for pure culture must be sterilized to maintain a sterile state. Edible mushroom culture media are prone to bacterial growth, so sterilization is necessary before culturing edible fungi.

[0003] Existing media sterilization devices generally employ a box-type structure. Before sterilization, the media is first loaded into the box, then the sterilization components are activated to sterilize the media. Because the media accumulates inside the box, it is inconvenient to sterilize the media in the inner layers of the box after the sterilization components are activated. Therefore, the sterilization of the media is incomplete and cannot be performed continuously, making it unsuitable for continuous production lines.

[0004] In the prior art, patent document CN217448500U discloses a simple sterilization device for edible fungi culture medium. This sterilization device, during operation, utilizes a sterilization cabinet, ultraviolet lamps, a fixed plate, a through-slot, a top rod, a placement plate, rollers, a cam, a rotating shaft, a motor, a connecting plate, a first spring, a heating component, and a guiding component. The top rod is slidably connected to the through-slot, and the placement plate can move up and down, preventing culture medium accumulation and facilitating sterilization of other surfaces of the culture medium, thus improving the sterilization effect. However, this device cannot perform continuous sterilization operations; it can only sterilize the culture medium placed on the placement plate sequentially, making it unsuitable for use on production lines.

[0005] Patent document CN208987709U discloses a sterilization box for edible fungi. Inside the sterilization box, there is a rack for placing edible fungi. This rack rotates under the drive of a motor. During rotation, the airflow inside the box is evenly distributed, and gears simultaneously rotate the edible fungi, achieving a good sterilization effect. However, this technical solution also suffers from the problem of not being able to perform continuous sterilization operations, making it unsuitable for use on production lines.

[0008] Specifically, the horizontal conveying assembly includes a driven wheel and a driving wheel respectively installed at the front and rear ends of the frame. The driven wheel and the driving wheel are connected by a conveyor belt. A drive motor is fixed at the rear end of the frame, and the output shaft of the drive motor is connected to the driving wheel by a transmission assembly.

[0009] Specifically, multiple upper rollers are evenly distributed and rotatably arranged in the horizontal direction within the frame, supporting the straight section at the upper end of the conveyor belt.

[0026] 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.

[0027] Example 1: Refer to Figures 1-4 As shown, an ultraviolet sterilization box for edible fungi culture medium includes a frame 1, a horizontal conveying component is provided on the frame 1, a box body 2 is fixed to the upper end of the frame 1, the horizontal conveying component passes through the box body 2, and sealing plates 3 are fixed to both the left and right ends of the box body 2, with a gap between the lower end of the sealing plate 3 and the upper end of the horizontal conveying component.

[0028] Multiple ultraviolet lamps 4 are evenly distributed and fixed in the horizontal direction inside the housing 2, and the multiple ultraviolet lamps 4 are located above the horizontal conveying component.

[0029] The horizontal conveying assembly includes a driven wheel 5 and a driving wheel 6 respectively installed at the front and rear ends of the frame 1. The driven wheel 5 and the driving wheel 6 are connected by a conveyor belt 9. A drive motor 7 is fixed at the rear end of the frame 1. The output shaft of the drive motor 7 is connected to the driving wheel 6 by a transmission assembly.

[0030] The transmission assembly includes sprockets fixed on the output shaft of the drive motor 7 and the axle of the drive wheel 6, and the two sprockets are connected by chain drive.

[0031] Multiple upper rollers 8 are evenly distributed and rotated in the horizontal direction within the frame 1. The upper rollers 8 support the straight section at the upper end of the conveyor belt 9. Multiple lower rollers 14 are evenly distributed and rotated in the horizontal direction within the frame 1. The lower rollers 14 support the straight section at the lower end of the conveyor belt 9.

[0032] A lifting assembly is installed in the middle of the housing 2, and a vibration blocking assembly is fixed at the lower end of the lifting assembly. A second detection unit is installed at the rear end of the vibration blocking assembly.

[0033] Multiple trays 10 are conveyed sequentially at the top of the horizontal conveying assembly, and edible fungi culture medium is placed in each tray 10.

[0034] A first detection unit is provided on the frame 1 at the front of the vibration blocking component. After the tray 10 is detected by the first detection unit, the lifting component drives the vibration blocking component to descend for the first time. After the rear end of the vibration blocking component blocks the rear end of the tray 10, the second detection unit detects the tray 10. The lifting component then drives the vibration blocking component to descend again. After the vibration blocking component descends again, it holds the front and rear ends of the tray 10. Then, the vibration blocking component causes the tray 10 to vibrate and causes the edible fungus culture medium inside the tray 10 to turn over.

[0035] The lifting assembly includes a telescopic rod 15 located inside the housing 2. The upper end of the telescopic rod 15 is fixedly connected to the top plate of the housing 2. The telescopic rod 15 is an electric telescopic rod and is electrically connected to the controller via a relay.

[0036] The vibration damping assembly includes a lifting plate 18, which is horizontally positioned and fixedly connected to the lower end of a telescopic rod 15. Multiple vertically positioned guide rods 17 are fixedly mounted on the upper end of the lifting plate 18, and each guide rod 17 is slidably fitted with a fixing sleeve 16. The fixing sleeve 16 is fixed to the upper end of the top plate of the housing 2. A vibrator 20 is fixedly mounted on the upper end of the lifting plate 18. A rear baffle 19 is fixedly mounted at the rear end of the lifting plate 18 and is vertically positioned. A front baffle 21 is fixedly mounted at the front end of the lifting plate 18 and is vertically positioned. The height of the front baffle 21 is less than the height of the rear baffle 19. A guide slope is machined at the lower end of the front baffle 21. The vibrator 20 is electrically connected to a controller via a relay.

[0037] The first detection unit includes a bracket 12, which is fixed to the upper end of the frame 1. A front photoelectric sensor 13 is fixed on the bracket 12 and is electrically connected to the controller.

[0038] The second detection unit includes a rear photoelectric sensor 22, which is fixed on the rear baffle 19 and electrically connected to the controller.

[0039] When sterilizing the edible fungus culture medium, multiple trays 10 are conveyed sequentially on the upper end of the horizontal conveyor assembly, and the edible fungus culture medium is placed in the tray 10. The tray 10 enters the box 2 through the gap between the front sealing plate 3 and the conveyor belt 9. The ultraviolet sterilization lamp in the box 2 can sterilize the edible fungus culture medium in the tray 10.

[0040] After the current photoelectric sensor 13 detects the tray 10, the front photoelectric sensor 13 sends a signal to the controller, and the controller starts the telescopic rod 15. The telescopic rod 15 drives the lifting plate 18, the front baffle 21, the rear baffle 19, the vibrator 20 and the rear photoelectric sensor 22 to descend for the first time.

[0041] After the lifting plate 18, front baffle 21, rear baffle 19, vibrator 20 and rear photoelectric sensor 22 descend for the first time, the tray 10 can pass through the space between the lower end of the front baffle 21 and the conveyor belt 9 and is then blocked by the rear baffle 19.

[0042] After the rear end of the tray 10 is blocked by the rear baffle 19, the rear photoelectric sensor 22 detects the tray 10 and sends a signal to the controller. The telescopic rod 15 drives the lifting plate 18, the front baffle 21, the rear baffle 19, the vibrator 20, and the rear photoelectric sensor 22 to descend again, causing the front baffle 21 and the rear baffle 19 to hold the front and rear ends of the tray 10.

[0043] After the telescopic rod 15 drives the lifting plate 18, front baffle 21, rear baffle 19, vibrator 20 and rear photoelectric sensor 22 to descend again, it triggers the limit switch inside the telescopic rod 15. The limit switch sends a signal to the controller, and the controller causes the vibrator 20 to start.

[0044] When the vibrator 20 is started, the timer module in the controller is started simultaneously. When the vibrator 20 vibrates, it causes the tray 10 and the culture medium in the tray 10 to vibrate through the front baffle 21 and the rear baffle 19. After the culture medium in the tray 10 is vibrated, it can be flipped over.

[0045] After the vibrator 20 vibrates for the set time, the timer module outputs a signal to the controller, which shuts off the vibrator 20 and causes the telescopic rod 15 to move the vibration blocking component upward to reset.

[0046] Since the telescopic rod 15 is an electrically operated telescopic rod, and a servo motor is installed inside the telescopic rod 15, in the above control steps, the controller, through its internal program, causes the servo motor inside the telescopic rod 15 to rotate a set number of revolutions when the vibration blocking component initially descends, thereby causing the vibration blocking component to complete its initial descent. When the vibration blocking component descends again, the controller, through its internal program, causes the servo motor inside the telescopic rod 15 to rotate a set number of revolutions in the opposite direction, thereby causing the vibration blocking component to return to its initial descent. When the telescopic rod 15 drives the vibration blocking component to return to its initial position, the controller causes the servo motor inside the telescopic rod 15 to rotate a set number of revolutions in the opposite direction, thereby causing the vibration blocking component to return to its initial position.

[0047] As the tray 10 moves within the chamber 2, the culture medium inside the tray 10 has been turned over, allowing multiple ultraviolet germicidal lamps on the rear side of the chamber 2 to continue sterilizing the edible fungus culture medium inside the tray 10. By turning over the edible fungus culture medium inside the tray 10, the sterilization effect on the edible fungus culture medium can be improved.

[0048] In this embodiment, the rear baffle 19 first blocks the rear end of the pallet 10. After the rear baffle 19 blocks the rear end of the pallet 10, the friction between the conveyor belt 9 and the pallet 10 under the action of the conveyor belt 9 allows the rear end of the pallet 10 to fit against the rear baffle 19. During the downward movement of the front baffle 21, it can avoid movement interference with the front end of the pallet 10. At the same time, a guide slope is provided at the lower end of the front baffle 21 to facilitate the front baffle 21 and the rear baffle 19 to hold the pallet 10.

[0049] Example 2: Based on Example 1, referring to... Figure 2 and Figure 4 As shown, a support plate 11 is fixed on the frame 1 below the lifting plate 18. The support plate 11 is located between the upper and lower straight parts of the conveyor belt 9. The support plate 11 is fixedly connected to the frame 1. The front and rear sides of the upper end of the support plate 11 are machined with rounded corners. The upper end of the support plate 11 is in contact with the lower end of the upper straight part of the conveyor belt 9.

[0050] By setting up the pallet 11, the pressure-bearing capacity of the conveyor belt 9 above the pallet 11 can be improved, and when the vibration component moves downward again, the front baffle 21 and the rear baffle 19 can effectively hold the pallet 10.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
