Description

Technical Field

[0001] The utility model relates to the technical field of microbial agent inoculation, in particular to a microbial agent inoculation device for potted plant biocontrol experiments. Background Art

[0002] Tobacco Fusarium root rot and black shank are common, highly contagious, and highly lethal tobacco diseases. They primarily infect tobacco plants through wounds and can also cross-contaminate irrigation water, causing disease. Existing chemical control agents are not only ineffective but also environmentally unfriendly. However, biological control using biocontrol bacteria that have antagonistic effects on tobacco Fusarium is highly effective, pollution-free, and residue-free, and will likely become a key approach to controlling tobacco root and stem diseases.

[0003] Screening for biocontrol bacteria with highly effective antagonistic effects requires extensive pot and field trials. For these pot trials, different types of biocontrol bacteria and pathogens must be inoculated via root irrigation. However, existing inoculation methods simply pour a diluted solution of the inoculum onto the root surface of tobacco plants, exposing the inoculum directly to the outside world and failing to penetrate deeply into the soil. This results in poor inoculation effectiveness and low efficiency. Therefore, it is necessary to provide a new inoculation device for potted biocontrol trials to address these technical issues. Utility Model Content

[0032] The injection cylinder 7 is fixedly mounted on the lifting plate 5, and a soil-returning mechanism 8 is installed on the injection cylinder 7. The soil-returning mechanism 8 includes a slide rod 81, which is slidably mounted on the injection cylinder 7, and a connecting rod 82 is fixedly mounted on the end of the slide rod 81 facing away from the injection cylinder 7, and an arc block 85 is fixedly mounted on the end of the connecting rod 82 facing the arc groove 601, and a guide rod 83 is fixedly mounted on the middle part of the slide rod 81, and the end of the guide rod 83 facing away from the slide rod 81 is inserted into the through hole provided in the lifting plate 5, and a return spring 84 is sleeved on the guide rod 83, one end of the return spring 84 is fixedly connected to the slide rod 81, and the other end of the return spring 84 is fixedly connected to the lifting plate 5;

[0033] Among them, a piston rod 71 is slidably installed in the injection cylinder 7, and an adapter sleeve 72 is fixedly installed on the bottom end of the injection cylinder 7 through the lifting plate 5. One side of the bottom end of the adapter sleeve 72 is connected to a liquid inlet pipe 73, and the liquid inlet pipe 73 is connected to the bottom end of the microbial agent box 2. A sealing bolt 74 is rotatably installed in the adapter sleeve 72. The bottom end of the adapter sleeve 72 is located above the liquid inlet pipe 73 and is connected to a liquid outlet pipe 75. The end of the liquid outlet pipe 75 facing away from the adapter sleeve 72 is inserted into the arc-shaped pressure plate 61. A liquid guide hole 701 is opened in the middle of the sealing bolt 74, and an annular groove 702 is opened at the bottom end of the sealing bolt 74. A liquid guide hole 2 703 connected to the liquid guide hole 701 is symmetrically opened in the annular groove 702.

[0034] It should be noted that: when in use, move to one side of the potted tobacco plant, then wrap the arc-shaped pressure plate 61 around the root of the tobacco plant, and then turn the handwheel 41 to drive the screw 4 to rotate, thereby driving the lifting plate 5 to move downward along the support frame 3. When moving, drive the scraper plate 62 to move downward, and shovel the soil in the pot between the two scraper plates 62. The two scraper plates 62 are tilted toward each other, and then control the handwheel 41 to drive the screw 4 to reverse, thereby driving the lifting plate 5 to move upward along the support frame 3. When moving, the scraper plate 62 shovels the soil, thereby completing the grooving. After the groove is opened, the annular groove 702 of the sealing bolt 74 is first screwed to connect with the liquid inlet pipe 73, and its top end blocks the liquid outlet pipe 75 for sealing, and the piston rod 71 is pulled upward to draw the bacterial agent dilution liquid in the bacterial agent box 2 into the injection cylinder 7, and then the sealing bolt 74 is screwed downward until the annular groove 702 is disengaged from the liquid inlet pipe 73 and the liquid outlet pipe 75 is opened, and then the piston rod 71 is pressed downward to inject the dilution liquid in the injection cylinder 7 into the opened groove through the liquid outlet pipe 75.

[0035] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 , locking universal wheels 11 are fixedly installed at the four corners of the bottom end of the base 1;

[0036] It should be noted that the use of the locking universal wheels 11 facilitates the movement of the base 1 and increases the maneuverability.

[0037] In the embodiments of the present invention, please refer to Figures 1 to 3 The bottom end of the arc-shaped pressing plate 61 is located outside the arc-shaped groove 601 and is provided with a plurality of tooth pins 63;

[0038] It should be noted that when the arc-shaped pressing plate 61 is pressed downward to open the groove, it drives the plurality of tooth nails 63 to press downward synchronously, thereby loosening the soil in the pot and facilitating the growth of the potted tobacco plants.

[0039] The working principle of the microbial agent inoculation device for potted plant biocontrol experiments provided by the utility model is as follows:

[0040] When in use, move to one side of the potted tobacco plant, then wrap the arc-shaped pressing plate 61 around the root of the tobacco plant, and then turn the hand wheel 41 to drive the screw 4 to rotate, thereby driving the lifting plate 5 to move downward along the support frame 3. When moving, the scraper plate 62 is driven to move downward, and the soil in the pot is shoveled between the two scraper plates 62. The two scraper plates 62 are tilted toward each other, so that the hand wheel 41 is controlled to drive the screw 4 to reverse, thereby driving the lifting plate 5 to move upward along the support frame 3. When moving, the scraper plate 62 shovels the soil, thereby completing the grooving. After grooving, first screw the annular groove 702 of the sealing bolt 74 and the liquid inlet pipe 7 3 docking, and its top end blocks and seals the liquid outlet pipe 75, pulls the piston rod 71 upwards, draws the diluent in the microbial agent box 2 into the syringe 7, then screws the sealing bolt 74 downwards until the annular groove 702 disengages from the liquid inlet pipe 73 and opens the liquid outlet pipe 75, then presses the piston rod 71 downwards to quantitatively inject the diluent in the syringe 7 into the opened groove through the liquid outlet pipe 75, after injection, presses the slide bar 81 again, and the slide bar 81 drives the arc block 85 through the connecting rod 82 to press the soil in the arc groove 601 back into the opened groove, completing the soil backfilling, thereby achieving quantitative and accurate microbial agent inoculation, which is convenient for improving the accuracy of the test;

[0041] Furthermore, when the arc-shaped pressing plate 61 presses downward to open the groove, it drives the plurality of tooth nails 63 to press downward synchronously, thereby loosening the soil in the pot and facilitating the growth of the potted tobacco plants.
