Description

Technical Field

[0001] The present application relates to the field of plant protection technology, and in particular to an intelligent integrated tree trunk drilling and drug injection device. Background Art

[0002] Punch-hole injection technology is a precision pesticide application method for trees. It works by drilling small holes of a specific size and depth into the trunk, injecting a liquid pesticide into the hole. Using atmospheric pressure and transpiration from the tree, the liquid is transported to the crown, thereby controlling pests and diseases. Compared to traditional powdering and spraying methods, this method offers advantages such as lower pesticide usage and less environmental pollution. It is an effective means of achieving precision pesticide application and reducing pesticide use and increasing efficiency.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0033] In the examples of this application, please refer to Figure 1-10As shown, the intelligent tree trunk drilling and injection integrated device mainly includes: a device body 1, which is internally formed with a liquid storage chamber 2 for storing liquid medicine and a battery compartment for placing a battery pack 3, a drilling mechanism and an injection mechanism are respectively provided on both sides thereof, and a caliber measuring mechanism for measuring the diameter of the tree trunk is provided on the top thereof, the drilling mechanism, the injection mechanism and the caliber measuring mechanism are powered by the battery pack 3, and a shoulder strap 4 for carrying is also provided on the device body 1; the drilling mechanism includes a drill rig 5, and the drill rig 5 includes a first output shaft 501, and a receiving hole 6 is provided at the center of the end of the first output shaft 501, an inner drill bit 502 and a micro motor 503 for driving the inner drill bit 502 to extend and retract in the receiving hole 6 are provided in the receiving hole 6, and the drilling mechanism can control the drilling rig 5 according to the data calculated by the caliber measuring mechanism. The inner drill bit 502 is retractable to correspond to drilling holes of different depths on the tree trunk; the injection mechanism includes an injection tube 12 connected to the liquid storage chamber 2 and an on-off valve 7 that controls the on-off of the injection tube 12, and a pump 8 that drives the liquid in the liquid storage chamber 2 to be discharged. The injection tube 12 is provided with a plurality of blocking sleeves 9, and the blocking sleeves 9 are made of a nanocellulose / polyacrylic acid composite with water-swelling properties. A stop block 11 is formed at the end of the injection tube 12 for limiting the blocking sleeve 9. Pushing the blocking sleeve 9 along the direction of the stop block 11 can cause the blocking sleeve 9 to detach from the stop block 11 and the injection tube 12. The injection mechanism is used to inject an appropriate amount of liquid medicine into the borehole opened by the drilling mechanism according to the data calculated by the diameter measuring mechanism, and use the blocking sleeve 9 to seal the borehole after swelling when exposed to water.

[0034] Specifically, the nanocellulose / polyacrylic acid composite expands 3–5 times its original volume after absorbing water, can completely block the holes in the tree trunk, and has stable performance in the pH range of 4–9 and at temperatures of -20°C–60°C. It adapts to changes in the tree growth environment and completely degrades in 12 months under natural conditions (the time can be adjusted through chemical modification), which corresponds exactly to one medication cycle.

[0035] In addition, a soft cushion is provided on the device body 1 to provide support for the head when the device body 1 is carried manually through the strap 4, making it more comfortable to use. Figure 1-2 The setting of the middle strap 4 is for reference only, and the worker's head can be guaranteed to rest on the cushion.

[0036] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0037] like Figure 1-2As shown, the diameter measuring mechanism includes a fan-shaped receiving panel 13 arranged on the top of the device body 1, and at least three laser emitters 14 are arranged in a fan-shaped array on the fan-shaped receiving panel 13. When in use, the worker's head blocks a small part of the fan-shaped receiving panel 13, which does not affect its reception of diffusely reflected laser light, that is, the worker's head will not have an adverse effect on the operation of the diameter measuring mechanism. The diameter measuring mechanism needs to be 50-100 cm away from the tree trunk when in use.

[0038] Furthermore, a calculation and control module is also provided in the device body 1. After the caliber measuring mechanism measures the trunk diameter, the calculation and control module can calculate the required dosage according to the trunk diameter, and control the micro motor 503 to drive the inner drill bit 502 to extend the length of the accommodating hole 6. Specifically, the diameter of the inner drill bit 502 is 2 cm, and the effective drilling depth can be adjusted in the range of 3-8 cm. The calculation and control module calculates the required length of the inner drill bit 502 extending from the accommodating hole 6 according to the trunk diameter φ (cm) measured by the caliber measuring mechanism through the formula - hole depth (cm) = max(min(trunk diameter φ × 0.15, 5), 3), so as to control the drilling depth on the trunk, so that the drill hole can be accurately drilled in the wood part of the trunk. In addition, the drilling height on the tree trunk is about 1.2m. When drilling, it is necessary to manually drill the hole obliquely downward on the tree trunk. The oblique downward does not need to be strictly controlled in accuracy and can be within the range of 45±15 degrees. Most of the wood chips generated during drilling can be naturally discharged with the operation of the inner drill bit 502. A small amount of wood chips remain in the hole in the tree trunk, but it will not affect the injection mechanism and injection operation and damage the health of the tree.

[0039] like Figure 4-5 As shown, a limiting groove 15 is provided on the side wall of the accommodating hole 6, and a lug 16 is formed on the side wall of the inner drill bit 502. The lug 16 slides in the limiting groove 15. In addition, a threaded hole 17 is axially provided on the inner drill bit 502. The cooperation between the lug 16 and the limiting groove 15 ensures that when the first output shaft 501 rotates, the inner drill bit 502 can rotate synchronously without relative rotation between the two, thereby achieving the effect of limiting and positioning.

[0040] Furthermore, the micro motor 503 is arranged at the bottom of the accommodating hole 6, and includes a second output shaft 504 which is a screw. The second output shaft 504 is threadedly engaged with the threaded hole 17. The micro motor 503 drives the inner drill bit 502 to extend and retract by rotating, and controls the inner drill bit 502 to be retracted or extended into the accommodating hole 6 by the forward and reverse rotation of the second output shaft 504.

[0041] Specifically, the first output shaft 501 is driven by a drive motor 31 disposed within the drill rig 5. A positive conductive ring 18 and a negative conductive ring 19 are formed on the first output shaft 501. These positive and negative conductive rings 18 and 19 provide pathways for power supply and signal transmission to the micro-motor 503 during rotation. Furthermore, a plurality of cutting blocks 32 are annularly disposed at the end of the first output shaft 501. The outer walls of the positive and negative conductive rings 18 and 19 are configured to contact brushes within the drill rig 5, while their inner walls communicate with contacts within the micro-motor 503. The conductive rings are insulated from each other and from the first output shaft 501. The cutting blocks 32 are used to cut an opening larger than the diameter of the drilled hole in the tree trunk to facilitate the subsequent installation of the plugging sleeve 9.

[0042] Furthermore, an operating handle 20 is formed on the drill rig 5, and a main switch 21 and an anti-fool switch 22 are provided on the operating handle 20. The drill rig 5 is connected to the battery pack 3 through a cable 23. The main switch 21 can be pressed only after pressing the anti-fool switch 22, thereby reducing accidents caused by misoperation.

[0043] like Figure 1 and Figure 8 As shown, the injection tube 12 includes an integrated hose portion 1201 and a hard tube portion 1202, one end of the hose portion 1201 is connected to the liquid storage chamber 2, the pump 8 is arranged on the device body 1, and the on-off valve 7 is arranged on the hard tube portion 1202, and a handle 24 is fixed on the hard tube portion 1202, and a control switch 33 is arranged on the handle 24. The hard tube portion 1202 is also provided with a clamping plate 25 for pushing the blocking sleeve 9. The control switch 33 is operated by toggling to control the switch of the on-off valve 7, and the switch of the pump 8 is also arranged on the device body 1.

[0044] Specifically, the device body 1 is also provided with a camera module 26 and a positioning and information transmission module 27. The camera module 26 is used to take on-site photos, and the positioning and information transmission module 27 includes a positioning module and a transmission module, which are used to obtain positioning and upload information. Before and after tree drilling and injection work, the camera module 26 is required to automatically take photos and record, while the positioning module obtains the positioning, and the transmission module continuously transmits photos, positioning and other related data to the back-end big data platform.

[0045] Furthermore, a placement seat 28 is provided on both sides of the device body 1 , a medicine storage hole 29 communicating with the liquid storage chamber 2 is opened on the top of the device body 1 , and a detachable sealing cover 30 is provided on the top of the medicine storage hole 29 .

[0046] like Figure 8-9As shown, the plugging sleeve 9 is fixed on the plugging ring 10, which is made of metal. A hole for the injection tube 12 is opened at the center of both. The plugging sleeve 9 is fixed in the hole of the plugging ring 10 and extends to one side of the plugging ring 10. After the inner drill bit 502 and the first output shaft 501 are used to open a hole in the tree trunk, when the injection mechanism is used, the plugging sleeve 9 and the plugging ring 10 are manually pushed through the pressing plate 25 to push the plugging sleeve 9 out of the stop block 11 and into the hole in the tree trunk. , and the blocking ring 10 fits exactly at the hole opening with the enlarged diameter of the cutting block 32. The blocking sleeve 9 and the blocking ring 10 are installed at the hole opening. After the installation of the blocking sleeve 9 is completed, the drug injection operation is immediately carried out. In addition, guide slopes 1101 are formed on both sides of the stop position to ensure that the blocking sleeve 9 and the blocking ring 10 will not separate from the drug injection tube 12 when not subjected to external force. When the clamping plate 25 is used to push, the blocking sleeve 9 and the blocking ring 10 can be driven and separated from the drug injection tube 12 through the guide slopes 1101.

[0047] The present application is applied to tree drilling and injection work in urban roadside trees, mountains, fields and other environments, and includes functions such as photography, positioning, and information transmission. When in use, the worker carries the device on his back and starts the operation after confirming that the tree needs to be supplemented with nutrients or prevented from diseases and pests; first, the device is started, the camera module 26 works and takes photos and records, the worker stands 50-100 cm away from the tree and starts the diameter measuring mechanism, the laser transmitter 14 emits laser, the laser is diffusely reflected by the trunk and received by the fan-shaped receiving panel 13, and the data is processed by the processor inside the diameter measuring mechanism, and the trunk diameter φ is output and transmitted to the calculation control module in the device body 1, the calculation control module processes the data and calculates the required extension amount of the inner drill bit 502 through a formula, and issues a command to control the micro motor 503 to rotate until the inner drill bit 502 reaches the specified position; then the worker can open the drill rig 5, drive the motor 31 to work, and open a hole obliquely downward; after the drilling is completed, the injection tube 12 is inserted into the hole, and then pushed and pressed Plate 25, push the blocking ring 10 and the blocking sleeve 9 into the hole, then open the on-off valve 7 and the pump 8, the pump 8 will automatically inject 110% of the hole volume into the trunk hole within 20-60s, when the blocking ring 10 contacts the liquid, it can expand rapidly in a short time (within 20s) to block the hole, after the injection is completed, the injection tube 12 is pulled out, the blocking sleeve 9 and the blocking ring 10 are left at the hole, and the blocking sleeve 9 can further expand until the hole is completely blocked, and then the injection tube 12 is pulled out. 2, the stop block 11 can also take away part of the blocking sleeve 9, so that the blocking sleeve 9 blocks the hole at its center. Of course, after the injection tube 12 is pulled out, an appropriate amount of liquid medicine or water can be added to make the blocking sleeve 9 expand and completely block it to achieve the required technical effect. Finally, the positioning and information transmission module 27 obtains the positioning and uploads photos and positioning information before and after the operation. In addition, the blocking sleeve 9 can still maintain a certain volume after losing water, blocking the hole, and can effectively prevent pests and diseases from living in the drilled hole.

[0048] It should be noted that the injection tube 12 is inserted into the hole for a short length (less than 1 cm) during injection, and the diameter of the injection tube 12 is relatively small (about 1 cm), so the volume of the hole occupied during injection is negligible.

To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
