[0067] Further, if Figures 1 to 4 As shown, the vaccination component includes: a liquid storage chamber 371, a plurality of infusion channels (not shown in the figure), a plurality of infusion tubes 372, a shunt tube 373 and a water pump 374; the liquid storage chamber 371 is arranged inside the carrier shell 1; the plurality of infusion channels are arranged inside the guide member 34, and the output port of any infusion channel is exposed to the bottom surface of the guide member 34, and the output port of any infusion channel is located at the head end of the guide member 34; the plurality of infusion tubes 372 are fixedly arranged inside the assembly chamber 31, and the output ends of the plurality of infusion tubes 372 are respectively connected to the input ends of the plurality of infusion channels; the shunt tube 373 is fixedly arranged at the bottom of the inner cavity of the liquid storage chamber 371, and the plurality of output ends of the shunt tube 373 are respectively connected to the input ends of the plurality of infusion tubes 372; the water pump 374 is fixedly arranged on the bottom wall of the inner cavity of the liquid storage chamber 371, and the output end of the water pump 374 is connected to the input end of the shunt tube 373.

[0070] Before the user uses the device for pathogen inoculation, the user needs to use a cutter to cut off the middle section of the absorbent paper tape 24 and make the cut position of the absorbent paper tape 24 be at the bottom of the guide member 34; when the user uses the device for pathogen inoculation, the user drives the active shaft 361 to rotate by controlling the driving knob 362. During the rotation of the active shaft 361, the ratchet mechanism 366 is used to transmit power, thereby driving the first retractable pulley 363 to rotate. During the rotation of the first retractable pulley 363, the meshing assembly relationship between the gear teeth of the first retractable pulley 363 and the gear teeth of the second retractable pulley 365 is used to drive the second retractable pulley 365 to rotate synchronously, thereby causing the first retractable pulley 363 to release the bacteria-carrying paper tape 2, and at the same time, the second retractable pulley 365 synchronously retracts the bacteria-carrying paper tape 2; During the synchronous rotation of the unwinding pulley 363 and the second rewinding pulley 365, the absorbent paper tape 24 of the bacteria-carrying paper tape 2 located at the guide member 34 is cut off.

As the rotation angle of the first rewinding pulley 363 and the second rewinding pulley 365 increases, the length of the absorbent paper tape 24 extending out of the output port 32 also increases, so that the user can cover the part of the absorbent paper tape 24 extending out of the output port 32 on the pathogen inoculation area of ​​the corn leaf. During the process of the user covering the absorbent paper tape 24 on the corn leaf, the user can use the bottom end of the guide plate 33 to smooth the absorbent paper tape 24.

[0071] When the angle sensor detects that the rotation angle of the driven shaft 364 increases, the angle sensor sends a detection signal to the water pump 374, and the water pump 374 starts after receiving the detection signal, thereby outputting the pathogen suspension stored in the liquid storage chamber 371 to the infusion tube 372 through the shunt tube 373, and then outputting the pathogen suspension to the infusion channel through the infusion tube 372, and outputting the pathogen suspension through the output port 32 of the infusion channel, so that the pathogen suspension can soak the absorbent paper tape 24 through the through hole 23 opened on the release paper tape 21, and at the same time promote the absorbent paper tape 24 to escape from the accommodating groove 22, so that the user can cover the absorbent paper tape 24 carrying the pathogen suspension on the pathogen inoculation area of ​​the corn leaf, and in this embodiment, the working time and output efficiency of the water pump 374 are positively correlated with the rotation angle of the driven shaft 364.

[0072] After the length of the absorbent paper tape 24 extending through the output port 32 meets the experimental requirements, the user can push the handle 353 toward the head end of the carrier shell 1 to push the blade 352 forward so that the blade 352 is inserted into the cutting groove 354, thereby cutting off the portion of the absorbent paper tape 24 extending through the output port.

[0074] 1. The device is provided with a supply module to quantitatively output the bacteria-carrying paper tape, so that the user can obtain the bacteria-carrying paper tape of a specific length according to the experimental needs, thereby enhancing the convenience of using the device and solving the defect of complicated operation steps in the prior art.

[0075] 2. The device adopts a bacteria-carrying paper tape with a structure including a release paper tape, a containing groove, a through hole and an absorbent paper tape, and uses a first retractable pulley to reel in the bacteria-carrying paper tape, a second retractable pulley to reel in the release paper tape, and a release paper tape with high toughness to transmit the absorbent paper tape, so that the user can release a specific length of absorbent paper tape by driving the first retractable pulley to rotate a certain angle, thereby further enhancing the convenience of use of the device.

[0076] 3. The device is provided with an angle sensor at the driven shaft to detect the rotation angle of the driven shaft, so that the amount of the pathogen suspension output by the water pump is proportionally positively correlated with the length of the output absorbent paper tape, thereby improving the practicality of the device.
