[0002] Culture medium refers to a nutrient substrate composed of different nutrients, which supplies the growth and reproduction of microorganisms, plants, or animals. During the processing of culture medium, it needs to be filled into containers in a sterile environment using filling equipment. However, existing culture medium filling equipment still has certain shortcomings in use, such as: Existing culture medium filling devices often result in residual culture medium dripping onto the outside of the container after filling, affecting its use. Most of them cannot prevent dripping, and when adjusting multiple filling heads, they can only be adjusted one by one, which is inefficient.

[0003] Based on this, a culture medium filling device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-5As shown, a culture medium filling device includes a mixing tank 1, a control box 2, a metering pump 3, and a liquid extraction hose 4. The control box 2 for centralized control is provided on one side of the mixing tank 1. The metering pump 3 for liquid extraction is connected to the inner wall of the control box 2 through a partition. The liquid inlet end of the metering pump 3 is connected to the liquid extraction hose 4 for liquid delivery. The other end of the liquid extraction hose 4 is connected to the riser pipe 5 for liquid inlet. The riser pipe 5 is connected to the inner wall of the mixing tank 1 through a bracket. A foot switch 6 for control is connected to one side of the control box 2 through a wire. The control box 2 is also connected to a support rod 7 for support through a pipe clamp. A support mechanism 8 for supporting the filling mechanism 9 is provided on the riser 7. The liquid outlet end of the metering pump 3 is connected to a delivery hose 10 for liquid delivery. The other end of the delivery hose 10 is provided with the filling mechanism 9 for discharging. The filling mechanism 9 is located inside the support mechanism 8.

[0029] In this embodiment, the culture medium raw material is poured into the mixing tank 1. The variable frequency motor in the mixing tank 1 is started by the motor controller, which drives the blades to stir and mix the culture medium raw material. The controller is connected through the front of the inner wall of the control box 2 to control the entire equipment. The pumping volume of the metering pump 3 is set according to the required filling bottle capacity. The metering pump 3 is started by stepping on the foot switch 6, and the mixed culture medium in the mixing tank 1 is pumped into the riser pipe 5 and sent into the metering pump 3 through the pumping hose 4. The metering pump 3 sends the liquid into the filling mechanism 9 through the delivery hose 10 and into the bottle. A J-shaped bracket is set on the outside of the riser pipe 5 and hung on the tank wall of the mixing tank 1. It is installed with bolts to the tank body. Each set of metering pump 3 corresponds to a set of boat-shaped switches. The boat-shaped switches are installed on the back of the control box 2 to control the on and off of the circuit of the metering pump 3. A set of master switches is installed on the top of the control box 2 to control the on and off of the entire circuit. An H-shaped partition is set in the control box 2 to separate the space and separate the electrical equipment from the metering pump 3 to prevent moisture from entering the electrical equipment.

[0030] In one embodiment, such as Figures 5-9 As shown, the support mechanism 8 includes a steel pipe frame 801 connected to the outside of the upright 7 by a clamp. The inner wall of the steel pipe frame 801 is provided with a limiting groove 802 for limiting the position, and a slider 803 is slidably connected to the inner wall of the steel pipe frame 801. A threaded rod 804 for limiting the slider 803 is threadedly connected above the slider 803. A nut 805 for limiting the slider 803 is threadedly connected to the outside of the threaded rod 804. The nut 805 abuts against the upper surface of the steel pipe frame 801.

[0031] In this embodiment, the steel pipe frame 801 can move up and down on the upright 7. The height of the steel pipe frame 801 is adjusted according to the height of the bottle, and then locked to the upright 7 by the clamp at the rear end of the steel pipe frame 801, thereby fixing the height of the steel pipe frame 801. Limiting grooves 802 are opened on both sides and the top of the steel pipe frame 801. By pushing the pipe buckle 807, the slider 803 can be driven to slide inside the steel pipe frame 801. The threaded rod 804 slides in the upper limiting groove 802 to prevent the slider 803 from falling out of the steel pipe frame 801. By tightening the nut 805 and pressing it against the upper surface of the steel pipe frame 801, the position of the slider 803 at the rear end is fixed.

[0032] In one embodiment, such as Figures 6-9 As shown, a scissor-type telescopic frame 806 is connected to one side of the slider 803 via a bearing. One end of the scissor-type telescopic frame 806 is connected to one side of the steel pipe frame 801 via a support plate. The end of the slider 803 away from the scissor-type telescopic frame 806 is connected to a pipe buckle 807 for limiting the injection mechanism 9 via a support rod.

[0033] In this embodiment, the rotating shaft inside the scissor-type telescopic frame 806 passes through the limiting groove 802 on one side of the steel pipe frame 801 and is connected to the slider 803 by a bearing. When the slider 803 on the last side moves, the scissor-type telescopic frame 806 is expanded or contracted, thereby driving multiple sets of sliders 803 to open and close evenly, and synchronously adjusting the distance between multiple sets of tube buckles 807 to align with the bottle mouths of the arranged bottles. The position of the slider 803 on the last side is fixed by tightening the nut 805, thereby fixing the position of all tube buckles 807.

[0034] In one embodiment, such as Figure 6 and Figure 10 As shown, the injection mechanism 9 includes an injection tube 901 disposed within a tube buckle 807. The injection tube 901 is connected to the end of the delivery hose 10, and a first perforated plate 902 for limiting the spring 905 is slidably connected to the inner wall of the injection tube 901. A smooth rod 903 for driving the second perforated plate 906 to move is provided inside the first perforated plate 902. The lower end of the smooth rod 903 is connected to a plug 904 for sealing by bolts. The plug 904 abuts against the inner wall of the injection tube 901.

[0035] In this embodiment, pulling the rod 903 upwards moves the plug 904 upwards, causing the plug 904 to block the end of the infusion tube 901, preventing residual culture medium from dripping and contaminating the bottle. In one embodiment, such as Figure 10 As shown, a spring 905 for resetting is sleeved on the outer side of the light rod 903. The upper end of the spring 905 abuts against a second hollow plate 906 for limiting the position. The second hollow plate 906 is slidably connected to the inner wall of the injection tube 901 and is fixedly connected to the upper end of the light rod 903.

[0036] In this embodiment, after the culture medium enters the infusion tube 901, its pressure pushes the plug 904 downward, opening the lower end of the infusion tube 901, and the culture medium flows into the bottle. When the plug 904 moves downward, it drives the smooth rod 903 and the second hollow plate 906 to move downward, squeezing the spring 905. When the metering pump 3 stops, the pressure inside the infusion tube 901 disappears, and the spring 905 pushes the second hollow plate 906, the smooth rod 903 and the plug 904 to reset, quickly sealing the lower end of the infusion tube 901 and preventing the culture medium from dripping.

[0037] In one embodiment, such as Figure 10 As shown, a sealing plate 907 for separation is fixedly connected to the inner wall of the injection pipe 901. A sliding rod 908 for moving the first hollow plate 902 is provided through a sealing ring inside the sealing plate 907. The sliding rod 908 is fixedly connected to the upper surface of the first hollow plate 902, and a circular plate 909 is bolted to the upper end of the sliding rod 908.

[0038] In this embodiment, the moving circular plate 909 drives the sliding rod 908 to push the first perforated plate 902 to move up and down, and adjusts the distance between the second perforated plate 906 and the first perforated plate 902 to adjust the preload of the spring 905. Then, the pressure required to open the plug 904 is adjusted according to the water pressure to prevent the spring 905 from being too strong while the water pressure is too low, which would cause the culture medium to drain slowly from the irrigation tube 901, or even prevent the plug 904 from opening.

[0039] In one embodiment, such as Figure 10 As shown, a screw 910 for driving is internally threaded onto a circular plate 909. The screw 910 is connected to the sealing plate 907 via a bearing, and the other end of the screw 910 is connected to the inner wall of the injection tube 901 via a bearing. A worm gear 911 is fixedly connected to the outer side of the screw 910, and a worm 912 is meshed with the outer side of the worm gear 911. The worm gear 911 and the worm 912 are used for transmission, and the worm 912 is connected to the inner wall of the injection tube 901 through a bearing.

[0040] In this embodiment, the worm gear 912 drives the worm wheel 911 to rotate, which can achieve self-locking. By rotating the worm gear 912, the worm wheel 911 and the lead screw 910 are rotated, thereby driving the circular plate 909 to move up and down, so as to adjust the pressure required to open the plug 904.

[0041] The above embodiment discloses a culture medium filling device, wherein a metering pump 3 is placed on a workbench and a foot switch 6 is placed under the operator's feet. Then, the culture medium raw material is poured into a mixing tank 1 and mixed. The bottles to be filled are arranged in an array on a tray and placed under a steel pipe rack 801. The last pipe buckle 807 is slid to adjust the distance between the bottle mouths of the multiple sets of filling tubes 901. The spacing of the multiple sets of filling tubes 901 is adjusted, and then the nut 805 is tightened. The controller panel at the front of the control box 2 is operated to set the capacity of the metering pump 3 to be drawn each time according to the capacity of the bottles. Each row of bottles is placed under the filling tube 901. The foot switch 6 is stepped on to start the metering pump 3, which draws out the culture medium from the mixing tank 1 and sends it into the filling tube 901. The water pressure pushes the plug 904 to open, allowing the culture medium to flow into the bottles. After the set capacity is discharged, the metering pump 3 is turned off, and the spring 905 drives the plug 904 to reset, immediately blocking the filling tube 901 to prevent residual culture medium from dripping out of the pipe.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
