Description

Technical Field

[0001] The present invention relates to the technical field of pesticide application devices, in particular to a precision pesticide application device for grassland Stellera chamaejasme. Background Art

[0002] Stellera chamaejasme belongs to the genus Stellera chamaejasme of the family Thymelaeaceae. Stellera ), commonly known as heartbreak grass, steamed bun flower, red match head, dull head flower red wolfsbane, etc., is widely distributed in natural grasslands in Northeast, Northwest and Southwest my country. It is a highly toxic perennial poisonous plant; Wolfsbane has a well-developed root system and strong reproductive ability, which can consume more soil nutrients and water, resulting in a reduction in available nutrients for other forages, resulting in a significant decrease in the yield and quality of high-quality forage, seriously hindering the development of local grassland animal husbandry. Traditional prevention and control methods mainly rely on manual digging or large-scale spraying of chemicals. Due to the large area of wolfsbane occurrence and the high difficulty of physical prevention, chemical prevention is still the main means of grassland wolfsbane prevention and control. With the continuous enhancement of people's awareness of ecological environmental protection and the need to develop ecological organic animal husbandry, it is strictly forbidden to use high-residue pesticides on a large scale on natural grasslands to prevent and control grassland pests. Therefore, precise targeted application of chemical pesticides has become a basic requirement for pesticide use.

[0003] However, traditional spray application methods make it difficult to accurately target the roots of Stellera chamaejasme, resulting in waste of liquid medicine and easy pollution of the surrounding environment, while also causing damage to non-target plants; the roots of adult Stellera chamaejasme plants are highly lignified, and conventional injection application methods have difficulty penetrating the cortex, resulting in reduced efficacy and easy clogging of the syringe, affecting subsequent injection of liquid medicine; manual drilling and injection need to be carried out in steps, and the traditional device structure is complex, making it difficult for grassroots personnel to operate and having low operating efficiency. Existing application tools are mostly syringe-operated, and long-term operation can easily lead to operator fatigue, and cannot adapt to users of different body shapes or habits; professional tools are required to replace and clean the liquid medicine after the syringe has been used for a period of time, which increases maintenance costs.

[0039] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 13 As shown, the injection structure 4 includes a medicine mixing box 401 and a connecting pipe 402. The medicine mixing box 401 is installed on the assembly plate 1 through the mounting structure 5. Two connecting pipes 402 are fixedly connected to the medicine mixing box 401. Two connectors 403 are fixedly connected to the assembly plate 1. A first one-way valve 404 and a second one-way valve 405 are installed on the connector 403. The first one-way valve 404 is fixedly connected to the connecting pipe 402. The end of the second one-way valve 405 is fixedly connected to a needle 406. A screw cap 407 is threadedly connected to the medicine mixing box 401. Two injection cavities 408 are provided inside the assembly plate 1, and a piston 409 is slidably connected inside the injection cavity 408. A push rod 410 is provided on the piston 409, and the push rod 410 is slidably connected to the assembly plate 1; a connecting rod 411 is fixedly connected to the push rod 410, and the connecting rod 411 is slidably connected to the assembly plate 1, and a block 412 is fixedly connected to the connecting rod 411. Two scales 413 are fixedly connected to the assembly plate 1, and two guide rails 414 are fixedly connected to the assembly plate 1, and the connecting rod 411 is slidably connected to the guide rails 414.

[0040] The mounting structure 5 includes an inserting strip 501 and a card slot 502 provided on the inserting strip 501. The medicine mixing box 401 is fixedly connected to two inserting strips 501, and the inserting strip 501 is plugged into the assembly plate 1. The assembly plate 1 is slidably connected to two slides 503, and the slides 503 are fixedly connected to a card strip 504, and the card strip 504 is engaged with the card slot 502. A plurality of guide rods 505 are fixedly connected to the assembly plate 1, and the slides 503 are slidably connected to the guide rods 505. The outer sleeve of the guide rod 505 is provided with a spring 506, and the two ends of the spring 506 are fixedly connected to the slides 503 and the assembly plate 1 respectively; the end of the slide 503 is fixedly connected to a lever 507, and the lever 507 is fixedly connected to the end of the slide Sliding connection with the assembly plate 1; after the drilling is completed, the medicine is applied. Before applying the medicine, the screw cap 407 of the medicine mixing box 401 is opened first, the prepared medicine liquid is poured into the medicine mixing box 401, and then the screw cap 407 is tightened, and the push rod 410 in the injection structure 4 is pushed. The piston 409 slides in the injection cavity 408. The space at the front end of the piston 409 gradually becomes smaller, and the gas is discharged through the second one-way valve 405 and the needle 406. After the air at the front end of the piston 409 is drained, the push rod 410 is pulled again. Since the injection cavity 408 of the piston 409 is in a negative pressure state, the medicine liquid inside the medicine mixing box 401 will be extracted. The medicine liquid in the medicine mixing box 401 enters the injection cavity 408 through the connecting pipe 402, the first one-way valve 404, and the connector 403. When the medicine is extracted After being pulled to a certain level, the push rod 410 can be pushed again, and the liquid medicine passes through the connector 403 and the second one-way valve 405, and is finally injected into the bore of the Stellera chamaejasme through the needle 406. In the process of pushing the push rod 410, the relative positions of the mark block 412 and the scale 413 on the connecting rod 411 can be observed to accurately control the amount of liquid medicine injected and achieve targeted and accurate drug administration. The setting of the guide rail 414 improves the sliding stability of the connecting rod 411. At the same time, since an injection cavity 408 is provided on each side of the assembly plate 1, it is convenient for the operator to switch between the left and right hands for injection, which improves the comfort of operation. When the liquid medicine in the mixing box 401 is used up or needs to be replaced and cleaned, the lever 507 is toggled, and the lever 507 drives the slide bar 5 03 slides on the guide rod 505, compressing the spring 506, and the card strip 504 on the slide 503 disengages from the card slot 502 on the insertion strip 501 of the mixing medicine box 401. At this time, the mixing medicine box 401 can be pulled out from the assembly plate 1. After pulling it out, the threaded rotary joint at the end of the connecting pipe 402 can be rotated to separate it from the mixing medicine box 401, and the replacement of the mixing medicine box 401 is completed. After replacing the new mixing medicine box 401, align the insertion strip 501 on the mixing medicine box 401 with the slot on the assembly plate 1 and insert it, release the lever 507, and the spring 506 resets, pushing the slide 503 to make the card strip 504 re-engage the card slot 502, completing the installation of the mixing medicine box 401, and then connect the corresponding connecting pipe 402 to the interface of the mixing medicine box 401.

[0041] Specifically, such as Figure 4 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the adjustment structure 6 includes a fixed rod 601 and a fixed disk 602, a plurality of fixed rods 601 are fixedly connected to the rotating shaft 210, and a plurality of fixed rods 601 are fixedly connected to the fixed disk 602, a pressing rod 603 with a T-shaped cross-section is slidably connected to the assembly plate 1, and the T-shaped end of the pressing rod 603 is fixedly connected to two limiting columns 604, a plurality of limiting holes 605 are provided in a circumferential array on the fixed disk 602, the limiting columns 604 are plugged into the limiting holes 605, and a tension spring 606 is fixedly connected between the pressing rod 603 and the assembly plate 1; a guide column 607 is fixedly connected to the rotating shaft 210, and the pressing rod 603 is slidably connected to the guide column 607; it is necessary to adjust the angle of the handle 211 to improve the hand When holding the drilling tool 211 for comfort or storing the handle 211, the pressing rod 603 is pressed, and the limiting column 604 on the pressing rod 603 disengages from the limiting hole 605 on the fixed disk 602. At this time, the handle 211 can be rotated, and the handle 211 drives the rotating shaft 210, the fixed rod 601 and the fixed disk 602 to rotate together. After the handle 211 is rotated to a suitable angle, the pressing rod 603 is released, and under the action of the tension spring 606, the pressing rod 603 is reset, and the limiting column 604 is reinserted into the corresponding limiting hole 605 on the fixed disk 602 to complete the fixing of the angle of the handle 211.

[0042] When using the present invention, first, the user passes the finger ring 204 at the bottom of the assembly plate 1 and selects a suitable holding method according to the operating habits. If the user chooses to control through the finger ring 204, the device is fixed to the user's wrist through the Velcro male patch 208 and the Velcro female patch 209 on both sides of the assembly plate 1 to improve the operating stability. The first switch 205 on the finger ring 204 is pressed, and the corresponding motor 203 on the assembly plate 1 is started, driving the drill bit 202 to rotate, drilling the lignified root of Stellera chamaejasme to avoid clogging the needle hole during subsequent injection. If the user chooses to operate by holding the handle 211, hold the handle 211 and press the handle 211. The second switch 212 is turned on, and the other motor 203 is started, driving the drill bit 202 to perform the drilling operation. The line of the first switch 205 is led out from the wiring groove 305 of the finger ring 204, and is connected to the corresponding motor 203 through the threading hole 304 of the assembly plate 1. The power connection line of the battery 206 is connected to the corresponding motor 203 through the third channel 303. The line of the second switch 212 is led out from the second channel 302 of the handle 211, and is connected to the other motor 203 through the first channel 301 of the assembly plate 1. When the handle 211 is rotated, the line will twist synchronously with the rotating shaft 210. 5-10cm of slack must be reserved for the line to prevent excessive stretching;

[0043] Then, after the drilling is completed, the medicine is applied. Before applying the medicine, the screw cap 407 of the medicine mixing box 401 is opened first, the prepared medicine solution is poured into the medicine mixing box 401, and then the screw cap 407 is tightened, and the push rod 410 in the injection structure 4 is pushed. The piston 409 slides in the injection cavity 408.

In the process of pushing the push rod 410, the relative positions of the mark block 412 and the scale 413 on the connecting rod 411 can be observed to accurately control the amount of liquid medicine injected and achieve targeted and precise drug administration. The setting of the guide rail 414 improves the sliding stability of the connecting rod 411. At the same time, since there is an injection cavity 408 on each side of the assembly plate 1, it is convenient for the operator to switch between the left and right hands for injection, which improves the operating comfort. When the liquid medicine in the mixed medicine box 401 is used up or needs to be replaced and cleaned, the lever 507 is toggled, and the lever 507 drives the slide 503 to slide on the guide rod 505, compressing the spring 506, and the card strip 504 on the slide strip 503 is separated from the card slot 502 on the insertion strip 501 of the mixed medicine box 401. At this time, the mixed medicine box 401 can be 01 is pulled out from the assembly plate 1.

Release the lever 507, the spring 506 resets, pushes the slide bar 503 to make the card strip 504 re-engage the card slot 502, and completes the installation of the mixing box 401. Then, the corresponding connecting tube 402 is connected to the interface of the mixing box 401.

[0044] Finally, when it is necessary to adjust the angle of the handle 211 to improve the comfort of hand-held drilling or to store the handle 211, press the pressing rod 603, and the limiting column 604 on the pressing rod 603 will disengage the limiting hole 605 on the fixed disk 602. At this time, the handle 211 can be rotated, and the handle 211 drives the rotating shaft 210, the fixed rod 601 and the fixed disk 602 to rotate together. After the handle 211 is rotated to a suitable angle, release the pressing rod 603. Under the action of the tension spring 606, the pressing rod 603 is reset, and the limiting column 604 is reinserted into the corresponding limiting hole 605 on the fixed disk 602 to complete the fixing of the angle of the handle 211.
