[0003] When cultivating existing seedlings, it is necessary to strictly prevent the harm of pests and diseases. Otherwise, due to factors such as the small planting spacing between seedlings and the concentrated planting of the same variety, it is easy to cause the mutual infection of pests and diseases, resulting in serious economic losses.

[0004] Currently, for pest control and killing of seedlings, spraying equipment is mainly used for large-scale spraying of pesticides. For example, the invention patent with the publication number CN113439735B discloses a mobile pesticide spraying device for agricultural planting, which can automatically spray pesticides to both sides under manual traction. However, the pesticide spraying method of this device is simple, only the branches and leaves on the surface of the plant are sprayed, and it is impossible to spray the inner branches and leaves close to the trunk and branches, thus reducing the use effect of pesticides; secondly, a large amount of pesticides are sprayed into the air, which is wasted under the blowing of the wind and will cause environmental pollution.

Detailed implementation manners

[0032] In order to clearly and completely describe the objectives and technical solutions of the present invention and more clearly explain its advantages, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0033] Embodiment 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 And Figure 8, the present invention provides a pest control and killing device for forestry seedlings, including a traveling device 1 and a lifting frame 16. The traveling device 1 is used to advance periodically at a fixed interval along the guide rail 12, and the guide rail 12 is laid in the seedling planting field. Above the traveling device 1, a medicine storage tank 8 and a lifting push rod 15 are fixedly installed, and a controller 13 is installed on the traveling device 1. At least a pair of connecting frames 7 are provided on the lifting frame 16, and at least a pair of inserting devices 4 for inserting from the top of the seedling into the root of the seedling are provided below each connecting frame 7. A spraying device 6 is provided on the inserting device 4. A first liquid supply pump 5 for pumping out the spraying-type medicine located in the medicine storage tank 8 and sending it into the spraying device 6 for spraying is provided on the medicine storage tank 8. Both the first liquid supply pump 5 and the lifting push rod 15 are electrically connected to the controller 13. The controller 13 can drive the lifting push rod 15 to insert the inserting device 4 from the gaps between the leaves and branches at the top of the seedling down to the root area of the seedling. When the spraying device 6 passes through the leaf area of the seedling, the first liquid supply pump 5 will, under the drive of the controller 13, send the spraying-type medicine located in the medicine storage tank 8 into the spraying device 6, and then the spraying device 6 will spray the spraying-type medicine onto the leaves and branches of the seedling. The main components of the spraying-type medicine can be selected according to the type of the seedling and the need for pest control and killing, such as common medicines like lime sulfur mixture, avermectin, imidacloprid, etc.

[0034] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the inserting device 4 includes an outer sleeve 401 fixedly installed with the connecting frame 7, and a moving device 3 is arranged inside the outer sleeve 401. The moving device 3 includes a central rod 302 slidably installed inside the outer sleeve 401. The top of the central rod 302 is connected to the top of the outer sleeve 401 through a return spring 404. A pressing piece 305 for contacting the ground is fixedly installed at the bottom of the central rod 302, and a travel switch 10 triggered by the pressing of the pressing piece 305 is arranged at the bottom of the outer sleeve 401. The travel switch 10 is electrically connected to the controller 13. When the traveling device 1 moves forward a specified interval, the lifting push rod 15 will insert the inserting device 4 downward from the top of the seedling until the pressing piece 305 contacts the ground. At this time, the pressing piece 305 cannot continue to descend, so the central rod 302 will stop moving downward and the central rod 302 will slide relative to the outer sleeve 401, thereby compressing the return spring 404. Subsequently, the pressing piece 305 contacts the travel switch 10 to trigger the travel switch 10. After receiving the signal sent by the travel switch 10, the controller 13 will control the lifting push rod 15 to lift the inserting device 4 upward again until it is completely pulled out above the seedling. During the up and down movement of the inserting device 4, the spraying device 6 will spray the spraying-type medicine onto the branches and leaves of the seedling.

[0035] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , a plug head 306 for inserting into the soil is fixedly installed at the bottom of the central rod 302. A central flow channel 307 for injecting an injection-type medicament into the soil is arranged in the plug head 306. A second liquid supply pump 9 is fixedly installed on the medicine storage tank 8. The second liquid supply pump 9 is used to extract the injection-type medicament located in the medicine storage tank 8 and send it into the central flow channel 307 for injection into the soil. The second liquid supply pump 9 is electrically connected to the controller 13. When the travel switch 10 is triggered, the controller 13 will control the lifting push rod 15 to stop moving for a specified duration, and then make the lifting push rod 15 move upward. During the time when the lifting push rod 15 stops, the second liquid supply pump 9 will extract the injection-type medicament located in the medicine storage tank 8 and then inject it into the soil through the central flow channel 307, so as to kill the insects and insect eggs in the soil. The main components of the injection-type medicament can be selected according to the usage needs, such as Paecilomyces lilacinus, imidacloprid, calcium magnesium silicon clothianidin and other medicaments.

[0036] Please refer to Figures 1 to 3 , the traveling device 1 includes a vehicle frame 101 slidably installed on the guide rail 12. The vehicle frame 101 is used to install the medicine storage tank 8 and the lifting push rod 15. A driving motor 102 is fixedly installed on the vehicle frame 101. A driving gear 103 is rotatably installed on the vehicle frame 101. The output end of the driving motor 102 drives the driving gear 103 to rotate through a belt. A rack 11 meshed with the driving gear 103 is installed on the guide rail 12. The driving motor 102 is electrically connected to the controller 13. The controller 13 can control the driving motor 102 to rotate, so as to drive the gear 103 to rotate by the driving motor 102 and move along the rack 11, so that the vehicle frame 101 can move along the guide rail 12. The driving motor 102 adopts a stepping motor, and the traveling distance of the traveling device 1 is the same as the planting distance of the seedlings, so as to ensure that the inserting device 4 can correctly perform the inserting operation. A storage battery or a lithium battery pack can be installed on the vehicle frame 101 to supply electric energy to electrical equipment such as the controller 13.

[0037] In this embodiment, the drive motor 102 will periodically move forward along the guide rail 12 under the control of the controller 13, and the distance traveled each time is the same as the planting spacing of the seedlings, so that the vehicle frame 101 stops at a designated time near each seedling. When the vehicle frame 101 stops near the seedling, the insertion device 4 will move downward under the drive of the lifting push rod 15. After that, not only can the spraying device 6 spray the spraying-type medicament onto the branches and leaves, but also the central rod 302 can inject the injection-type medicament into the soil, so as to achieve pest control and insect extermination. Subsequently, the insertion device 4 is lifted again to the top of the seedling by the lifting push rod 15, so that it can move above the next seedling driven by the traveling device 1. By adopting this method, the leaves, branches and roots of the seedlings can be well protected from pests and insects at one time. Moreover, since the spraying device 6 can be inserted into the leaves and branches for spraying, the spraying on the leaves and branches can be more uniform, and the effect of pest control and insect extermination is better. It solves the problems of serious waste of medicament and poor spraying effect of the existing medicament spraying equipment, and can effectively improve the effect of pest control and insect extermination on the seedlings.

[0038] Embodiment 2: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9, on the basis of the first embodiment, the spraying device 6 includes an upper diversion cavity 603, a middle diversion cavity 605, and a lower diversion cavity 607 arranged in sequence from top to bottom on the outer sleeve 401. An upper inclined spray hole 601 for spraying the ejection-type medicament upward is provided on the outer side of the upper diversion cavity 603, and an upper docking hole 602 is provided on the inner side of the upper diversion cavity 603. A horizontal spray hole 606 for horizontally spraying the ejection-type medicament is provided on the outer side of the middle diversion cavity 605, and a middle docking hole 604 is provided on the inner side of the middle diversion cavity 605. A lower inclined spray hole 609 for spraying the ejection-type medicament downward is provided on the outer side of the lower diversion cavity 607, and a lower docking hole 608 is provided on the inner side of the lower diversion cavity 607. A sealing sleeve 303 for closing the upper docking hole 602, the middle docking hole 604, and the lower docking hole 608 is provided on the central rod 302. A diversion hole 308 communicating with the first liquid supply pump 5 is provided on the sealing sleeve 303. During the process of the central rod 302 sliding downwards, the diversion hole 308 is sequentially docked with the upper docking hole 602, the middle docking hole 604, and the lower docking hole 608, and the ejection-type medicament is respectively sent into the upper diversion cavity 603, the middle diversion cavity 605, and the lower diversion cavity 607. A friction collar 301 is provided on the outer wall of the central rod 302, and the frictional force between the friction collar 301 and the outer sleeve 401 is used to slow down the movement speed of the central rod 302, thereby delaying the time for the central rod 302 to return to the initial position under the push of the return spring 404. As a result, when the diversion hole 308 is docked with the upper docking hole 602, the middle docking hole 604, and the lower docking hole 608, there is sufficient time to provide enough spraying-type medicament for the upper diversion cavity 603, the middle diversion cavity 605, and the lower diversion cavity 607, and the upper inclined spray hole 601, the horizontal spray hole 606, and the lower inclined spray hole 609 have enough time to spray the corresponding areas of the leaves and branches. Moreover, a guiding protrusion 304 is fixedly installed on the outer wall of the central rod 302, and a guiding chute 403 slidably matched with the guiding protrusion 304 is provided at the bottom of the outer sleeve 401, thereby preventing the central rod 302 from rotating relative to the outer sleeve 401 and affecting the normal operation of the device.When the lifting push rod 15 lifts upward the inserting device 4, the first liquid supply pump 5 will also be turned on until the inserting device 4 is lifted to the topmost position. At the same time, the central rod 302 will also move downward under the pushing of the return spring 404. Specifically, when the diversion hole 308 is docked with the upper docking hole 602, at this time, the spraying device 6 is still located below the leaf area of the seedlings, so that the upper inclined spray holes 601 can be used to spray the leaves and branches at the bottom of the leaf area of the seedlings. When the diversion hole 308 is docked with the middle docking hole 604, the spraying device 6 has moved to the middle of the leaf area of the seedlings. At this time, the horizontal spray holes 606 can be used to effectively spray the leaves and branches inside the leaf area. When the diversion hole 308 is docked with the lower docking hole 608, the spraying device 6 has moved to the top of the leaf area of the seedlings. Therefore, the lower inclined spray holes 609 are used to spray the top of the leaf area, which can effectively prevent the sprayed pesticide from being sprayed into the air, thus effectively avoiding the waste of the sprayed pesticide. At the same time, it can also make the sprayed pesticide be sprayed more evenly on the leaves and branches. Further, it solves the problems of serious pesticide waste and poor spraying effect of the existing pesticide spraying equipment, and can effectively improve the pest control effect on the seedlings.

[0039] Embodiment 3: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10, on the basis of the second embodiment, an arc-shaped housing 402 is integrally formed at the bottom of the outer sleeve 401, and a coating device 2 is arranged inside the arc-shaped housing 402. The coating device 2 includes an arc-shaped elastic sheet 201 installed inside the arc-shaped housing 402. The upper end of the arc-shaped elastic sheet 201 is connected to the outer sleeve 401, and the lower end of the arc-shaped elastic sheet 201 is connected to the central rod 302. A brush piece 204 is arranged on the outer side of the arc-shaped elastic sheet 201. A telescopic hose 202 for spraying a coating-type medicament onto the trunk of the seedling is arranged on the arc-shaped elastic sheet 201. A third liquid supply pump 14 is fixedly installed on the medicine storage tank 8, and the output end of the third liquid supply pump 14 is communicated with the telescopic hose 202. The third liquid supply pump 14 is electrically connected to the controller 13, and the third liquid supply pump 14 is used to pump out the coating-type medicament located in the medicine storage tank 8 and send it into the telescopic hose 202. An anti-disengagement rod 203 is installed on the arc-shaped elastic sheet 201 and inserted into the arc-shaped housing 402 to guide the arc-shaped elastic sheet 201 to return into the arc-shaped housing 402. When the central rod 302 is pressed by the ground and pressed into the outer sleeve 401, the distance between the upper and lower ends of the arc-shaped elastic sheet 201 becomes smaller, so that the middle part of the arc-shaped elastic sheet 201 is squeezed and deformed and extends out of the arc-shaped housing 402. In this way, the outer wall surface of the arc-shaped elastic sheet 201 and the brush piece 204 can be pressed against the trunk of the seedling. After the insertion device 4 is inserted into the ground to complete the injection of medicine into the soil and is driven upward by the lifting push rod 15, the controller 13 controls the third liquid supply pump 14 to supply the coating-type medicament into the telescopic hose 202, so as to coat the coating-type medicament from bottom to top on the surface of the trunk by using the telescopic hose 202, and use the brush piece 204 to evenly brush the coating-type medicament onto the trunk. The coating-type medicament can use insecticidal and pest-control components such as lime water as the main components. Since the arc-shaped elastic sheet 201 can be deformed, when there are obstacles on the trunk, the arc-shaped elastic sheet 201 can also retract into the arc-shaped housing 402, and then use the arc-shaped outer surface of the arc-shaped housing 402 to cross the obstacles, such as crossing small branches. And because the arc-shaped elastic sheet 201 has a certain elasticity, it can still adhere to the surface of the trunk when the trunk is bent. When a plurality of arc-shaped elastic sheets 201 clamp the trunk from different angles, the trunk can be coated in all directions. The arc-shaped elastic sheet 201 can be made of metal sheets or plastic sheets. When the central rod 302 slowly returns to the initial position under the push of the return spring 404 and the slowdown of the friction collar 301, the arc-shaped elastic sheet 201 will be pulled by the central rod 302 and retracted into the arc-shaped housing 402, so as to be protected by the arc-shaped housing 402 and avoid being scratched by leaves or branches and damaged, so it is safer to use. Further solves the problems of serious waste of medicament and poor spraying effect of the existing medicament spraying equipment, and can effectively improve the insecticidal and pest-control effect on seedlings.

[0040] Embodiment 4: Please refer to Figures 1 to 3, on the basis of Embodiment 3, a horizontally arranged horizontal push rod 17 is fixedly installed on the lifting frame 16, and a connecting plate 18 is fixedly installed at the output end of the horizontal push rod 17. The connecting plate 18 is used to install the connecting frame 7, and the horizontal push rod 17 is electrically connected to the controller 13. Both the horizontal push rod 17 and the lifting push rod 15 are hydraulic push rods or pneumatic push rods, and the controller 13 is a PLC controller. The horizontal push rod 17 can be used to adjust the position of the connecting frame 7 relative to the guide rail 12, so that the connecting frame 7 can adapt to the planting spacing of different types of seedlings relative to the guide rail 12, facilitating the adjustment of the working position of the insertion device 4 according to different seedling planting spacings, making the equipment have better general performance. Further solving the problems of serious waste of pesticides and poor spraying effect of existing pesticide spraying equipment, it can effectively improve the pest control effect on seedlings.

[0041] Embodiment 5: On the basis of Embodiment 4, the present invention also provides a method for using a forestry seedling pest control and killing device, including the following steps:

[0042] Step 1: When the device is in use, the drive motor 102 will periodically move forward along the guide rail 12 under the control of the controller 13, and the distance traveled each time is the same as the planting spacing of the seedlings, so that the vehicle frame 101 stops at a specified time near each seedling. When the vehicle frame 101 stops near the seedling, the horizontal push rod 17 adjusts the position of the connecting frame 7 according to the preset seedling spacing, so that the insertion device 4 enters the correct working position.

[0043] Step 2: Subsequently, the insertion device 4 will be driven by the lifting push rod 15 to insert from the top of the seedling to the root of the seedling. When the travel switch 10 is triggered, the controller 13 will control the lifting push rod 15 to stop moving for a specified duration. During the time when the lifting push rod 15 stops, the second liquid supply pump 9 will pump out the injection-type pesticide located in the medicine storage tank 8 and then inject it into the soil through the central flow channel 307, so as to kill the insects and insect eggs located in the soil.

[0044] Step 3: After the lifting push rod 15 stops moving, the insertion device 4 will move upward under the drive of the lifting push rod 15. At the same time, the central rod 302 will gradually return to its initial position under the drive of the return spring 404. Thus, during the return process of the central rod 302, the brushing device 2 is used to complete the brushing operation on the trunk of the seedling, and the spraying device 6 is used to complete the spraying operation on the leaves and branches. Subsequently, the equipment enters the next round of operation process.

[0045] Although the above description of the specific embodiments of the present application is provided for those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all applications and creations using the concept of the present application are within the scope of protection.
