Technical Field

[0001] The invention relates to the field of pathogen liquid inoculation, in particular to a pathogen liquid inoculator. Background Art

[0002] In the field of microbiological research and application, pathogen liquid inoculation is a crucial experimental operation. However, the traditional pathogen liquid inoculation method has many shortcomings, such as the flow rate and speed of the pathogen liquid are difficult to accurately control during the inoculation process, resulting in poor inoculation uniformity; the inoculator has a complex structure, which is not easy to clean and sterilize, increasing the risk of experimental contamination; single function and insufficient adaptability. Existing inoculators often have single functions and cannot adapt to the diverse needs of inoculation of different types of pathogen liquids, especially in terms of temperature control and inoculation mode. The inoculator has a limited scope of application and cannot meet the diverse needs of different experiments for the inoculation amount of pathogen liquid.

[0003] In response to the above problems, some improved pathogen liquid inoculators have appeared in the prior art. These inoculators have improved the accuracy and convenience of inoculation to a certain extent, but there are still some limitations. For example, although some inoculators can control the flow of pathogen liquid, the operation is complicated and not conducive to the quick start of experimenters; other inoculators, although simple in structure, lack the necessary pre-cooling function and cannot meet the requirements of pathogen liquid temperature for specific experiments.

[0004] Therefore, the present invention proposes a new pathogen liquid inoculator, aiming to overcome the deficiencies in the prior art and provide a pathogen liquid inoculator with simple structure, convenient operation, high precision and wide application range. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The pathogen liquid inoculator is provided with a drilling component and an injection component. In the pathogen inoculation experiment, when the motor A rotates, it can drive the hollow drill rod to rotate, so that the hollow drill rod can open a hole for pathogen liquid inoculation after rotation. After the drilling is completed, before the hollow drill rod is pulled out of the hole, the injection tube extends from the hollow drill rod, and then the injection tube squeezes the spore suspension into the hole. If spraying is required, the injection tube needs to be retracted into the hollow drill rod, and the pathogen liquid is sprayed out by high pressure, and then the hollow drill rod is controlled to rotate at a high speed. At this time, the pathogen liquid can enter the hollow drill rod, and then be thrown out from the spray hole under the action of the centrifugal force of the hollow drill rod. Then the tooth tip of the hollow drill rod is not only used for opening a hole, but also for dispersing the spore suspension. Therefore, various inoculation effects such as opening hole injection inoculation and diffusion inoculation can be achieved, and it has multiple experimental functions, so as to obtain more comprehensive experimental data.

[0020] 2. The pathogen liquid inoculator is provided with a compression storage component. After the pathogen liquid is put in, the motor B rotates to move the internal bacterial liquid to the injection tube. Since the diameter of the injection tube is much smaller than the inner diameter of the material box, the pathogen liquid can be sprayed out at high pressure. A spiral blade is provided, and mycelium can also be placed inside the material box. Through the rotation of the spiral blade, the mycelium will be squeezed into the injection tube, and then squeezed out of the injection tube into the hole opened in the hollow drill rod, so that a variety of inoculation materials such as mycelium and bacterial liquid can be used, which can meet the needs of different types of pathogens in various experiments.

[0021] 3. The pathogen liquid inoculator is provided with a moisturizing component and a heating wire. The heating wire can keep the inside of the material box warm and maintain a suitable temperature for storing the pathogen liquid to prevent the internal pathogens or spore hyphae from deteriorating. The atomization tube can spray atomized water into the material box at regular intervals to replenish water to the internal spore hyphae and prevent the death of the hyphae due to excessive dryness. It has flexible temperature and humidity control and reduces the risk of experimental contamination.

[0022] 4. The pathogen liquid inoculator is provided with a filling component. When the hollow drill rod drills into a certain depth, the bowl will fit the plant, and then the drilled debris will fall into the bowl. When the hyphae are squeezed into the hole, the micro air pump can be turned on to blow the debris in the bowl into the opened hole, or used to air-dry the pathogen liquid in the hole to prevent it from flowing out. The bowl can also receive the punched debris and collect the debris, so that the collected debris can also be used to fill the hole. It has a wide range of applications and meets various needs in different experiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 1, as Figure 1-8 As shown, a pathogen liquid inoculator comprises a shell 1, a compression storage component 2 is installed at one end of the shell 1, a drilling component 3 is installed at the other end of the shell 1, an injection component 4 connected to the compression storage component 2 is also installed at the other end of the shell 1, and a moisturizing component 5 connected to the compression storage component 2 is also installed inside the shell 1;

[0037] The drilling assembly 3 includes a hollow drill rod 301 and a power box 302. The power box 302 is installed outside one end of the housing 1 and the cavities between the two are connected. A large gear 303 is fixedly installed on one end of the hollow drill rod 301 inside the power box 302. The hollow drill rod 301 is rotatably connected to the power box 302. A motor A304 is also installed on the power box 302. A small gear 305 meshing with the large gear 303 is installed on the output shaft of the motor A304. The small gear 305 is in the power box 302. A circle of tooth tips 306 is fixedly installed at the end position of the hollow drill rod 301 away from the power box 302. A circle of spray holes 307 connected inside and outside are provided on the outer side wall of the end of the hollow drill rod 301 away from the power box 302.

[0038] The injection assembly 4 includes an injection tube 401, which is inserted into the hollow drill rod 301 and arranged concentrically therewith; it includes an electric push rod 402, and two electric push rods 402 are provided, one of which is fixed to the housing 1, and the other is fixed to the side of the injection tube 401. After the electric push rod 402 is extended, the injection tube 401 can be pushed out of the hollow drill rod 301, and the end of the injection tube 401 away from the hollow drill rod 301 is connected to the compression storage assembly 2.

[0039] The structure of the hollow drill rod 301 is similar to that of the traditional drill rod, with a spiral groove design on the outside and a hollow tubular structure on the inside. The spiral groove on the outside of the hollow drill rod 301 does not extend to its two ends, because a spray hole 307 needs to be designed at one end of the hollow drill rod 301. After adding the tooth tip 306, the drilling efficiency can be improved, and the fiber can be destroyed efficiently. Since the hollow drill rod 301 is adapted to softer plant fibers, the spray hole 307 is provided without affecting the drilling progress, and when the hollow drill rod 301 is in a rotating state, the spray hole 307 is not easy to be blocked.

[0040] The electric push rod 402 is an electro-hydraulic push rod, which can be extended or contracted under power control. A connecting frame is provided on the outside of the injection tube 401 for connecting with the movable shaft of the electric push rod 402.

[0041] A spring 403 is sleeved on the outside of one end of the injection tube 401, one end of the spring 403 is fixed to the side of the power box 302, and the other end of the spring 403 is fixed to the side of the injection tube 401. When the injection tube 401 extends from one end of the hollow drill rod 301 with the tooth tip 306, the spring 403 is compressed.

[0042] The spring 403 is used to stabilize the injection tube 401. Although the electric push rod 402 can extend or pull back the injection tube 401, the spring 403 can prevent the injection tube 401 from shaking, so that the injection tube 401 can always remain coaxial with the hollow drill rod 301 as much as possible.

[0043] One end of the injection tube 401 away from the hollow drill rod 301 is a trumpet-shaped structure, and an elastic tube 404 is fixedly installed at the trumpet-shaped structure of the injection tube 401. The other end of the elastic tube 404 is connected to the compression storage assembly 2.

[0044] When the electric push rod 402 drives the injection tube 401 to move, the elastic tube 404 does not affect the delivery of the internal pathogen liquid. The trumpet-shaped structure of the injection tube 401 can increase the pressure of the pathogen liquid flowing inside. However, due to the existence of the electric push rod 402, the internal high-pressure stock liquid will not cause the elastic tube 404 to expand.

[0045] The compressed material storage assembly 2 includes a material box 201, a motor B202, a rotating shaft 203, a spiral blade 204 and a feed nozzle 205. The material box 201 is fixed to the inner wall of the shell 1, the electric push rod 402 is fixed to the side of the material box 201, the motor B202 is fixed to the shell 1 and fixedly connected to the material box 201, the rotating shaft 203 is laterally inserted into the material box 201 and is rotatably connected thereto, the spiral blade 204 is fixed to the rotating shaft 203 and fits with the inner wall of the material box 201, one end of the feed nozzle 205 is fixed to the material box 201, and the two are connected, and the other end of the feed nozzle 205 passes through the shell 1;

[0046] The diameter of one end of the material box 201 close to the injection tube 401 is smaller than that of the other end thereof away from the injection tube 401 . The end of the elastic tube 404 away from the injection tube 401 is fixed to the material box 201 and communicated with the interior thereof.

[0047] The material box 201 is a hollow metal box with a temperature sensor attached to the outside and a humidity sensor inside. The feed nozzle 205 is used to input pathogenic bacteria liquid or spore hyphae. The spiral blade 204 can transport the internal raw materials toward the injection tube 401 when rotating.

[0048] A heating wire 206 is wound around the outside of the material box 201 to control the temperature inside the material box 201 .

[0049] The heating wire 206 is controlled by the control chip, and the heating time can be manually set or automatically determined to ensure that the inside of the material box 201 is always at a temperature suitable for the survival of mycelium. The temperature can be adjusted at any time according to the pathogen liquid and mycelium.

[0050] The moisturizing component 5 includes a combination tube 501, an atomizing tube 502, a water tank 503 and a water injection pipe 504. There are two combination tubes 501, which are respectively located on both sides of the material box 201. There are two groups of atomizing tubes 502, each group has a number of atomizing tubes arranged equidistantly. One end of one group of atomizing tubes 502 is connected to and communicated with one of the combination tubes 501, and the other end of the atomizing tube 502 is fixed to the material box 201 and communicated with the inside thereof. There are two water tanks 503, both of which are fixed to the side walls of the material box 201. Any combination tube 501 is connected to one of the water tanks 503. The water in the water tank 503 can enter the material box 201 in the form of water mist through the combination tube 501 and the atomizing tube 502. The water injection pipe 504 is fixedly penetrates the outer shell 1, and one end of the water injection pipe 504 located inside the outer shell 1 is fixed to and communicated with the two water tanks 503.

[0051] The water injection pipe 504 can add water to the two water tanks 503 at the same time. The combined pipe 501 is used to extract clean water from the water tank 503 and then transport it to the material box 201 through the atomization pipe 502. The water spraying time and water spraying flow rate are controlled by the control chip. The control chip determines the atomization time according to the humidity inside the material box 201. The humidification can also be actively controlled by the teaching experiment personnel.

[0052] Water pumps 505 are installed on the combined pipes 501 , and the water suction ends of the two water pumps 505 are connected to the two water tanks 503 respectively.

[0053] In an optional embodiment, a filling assembly 6 is further included. The filling assembly 6 is fixed on one end of the housing 1 , the filling assembly 6 is sleeved on the hollow drill rod 301 , and one end of the filling assembly 6 is fixed and sealed to the power box 302 .

[0054] The filling assembly 6 includes a bowl 601, a compression ring 602 and a micro air pump 603. The interior of the bowl 601 is a cavity structure. The hollow drill rod 301 passes through the bowl 601. The other end of the bowl 601 is sealed and fixed to the power box 302. The compression ring 602 is fixed to the end of the bowl 601 away from the power box 302. The micro air pump 603 is fixed on the housing 1. The blowing end of the micro air pump 603 is connected to the interior of the bowl 601 through an air pipe.

[0055] The compression ring 602 is a rubber ring, which can ensure a certain degree of fit and sealing after being compressed, and can transfer the debris brought out by the hollow drill rod 301 to the bowl 601. The micro air pump 603 connected to the bowl 601 is not only used for jetting but also for exhausting air, thereby achieving multiple effects such as collecting debris, air-drying pathogen liquid, and blowing out debris.

[0056] How it works:

[0057] Drilling inoculation experiment: Motor A304 rotates through small gear 305 to drive large gear 303 and then drive hollow drill rod 301 to rotate. The tooth tip 306 at the end of hollow drill rod 301 and the external structure can be used to drill holes. After drilling is completed and before hollow drill rod 301 is pulled out of the hole, electric push rod 402 contracts to make injection tube 401 extend out of hollow drill rod 301. At this time, motor B202 drives pathogen liquid in material box 201 to move into injection tube 401, and then the pathogen liquid is ejected from injection tube 401. The end of the hollow drill rod 301 is sprayed into the opened hole to realize punching inoculation. When the hollow drill rod 301 drills into a certain depth, the bowl 601 will fit the plant, and then the drilled debris will fall into the bowl 601. When the pathogen liquid is squeezed into the hole, the micro air pump 603 can be turned on to blow the debris in the bowl 601 into the opened hole, or used to air-dry the pathogen liquid in the hole to prevent it from flowing out. The bowl 601 can also receive the punched debris and collect the debris, and then manually stuff the collected debris into the hole;

[0058] Spraying inoculation experiment: the material box 201 needs to be filled with spore suspension or pathogen liquid. When it is opened, the motor B202 needs to be driven to rotate to push the pathogen liquid inside, changing the low pressure to high pressure, and then spraying it out from the injection tube 401. At this time, the injection tube 401 needs to be retracted into the hollow drill rod 301 under the extension force of the electric push rod 402, and then the hollow drill rod 301 is controlled to rotate at a high speed. At this time, the pathogen liquid can enter the hollow drill rod 301, and then be thrown out from the spray hole 307 under the action of the centrifugal force of the hollow drill rod 301. Then the tooth tip 306 of the hollow drill rod 301 is not only used to open the hole, but also used to disperse the spore suspension;

[0059] Preservation stage: pathogenic bacteria liquid, spore suspension and hyphae can be stored in the material box 201, and the heating wire 206 can provide a suitable temperature inside the material box 201. The temperature of the heating wire 206 is adjustable to prevent the death of the internal hyphae. The atomization tube 502 can spray atomized water into the material box 201 at a regular time to replenish the internal spore hyphae with water to prevent over-drying. Water can also be sprayed at the same time when squeezing the hyphae to reduce the resistance of squeezing, ensure the survival rate of the hyphae, improve the success rate of the experiment, and reduce the risk of experimental contamination.
