[0002] The control of trunk-boring pests is the most difficult type of pest to be controlled by the gardening and forestry departments. The main damage period is the larval stage of trunk-boring pests. The larvae first eat the bark and then enter the wood to eat, causing hollow branches and trunks to die or break and fall. Once the larvae enter the wood of the tree through their boreholes, it is difficult to find the traces and they are highly concealed. It is difficult to find the exact location of the larvae, making control difficult.

[0003] At present, there are many methods for preventing and controlling trunk-boring pests, such as artificial killing of adult insects, whitewashing of tree trunks to kill insect eggs, poison swabbing, injection of liquid medicine, etc. None of the above methods can effectively achieve the purpose of prevention and control, or the prevention and control effect is not good, and all of them cannot accurately apply pesticides to larvae.

[0026] Example 1

[0027] A preferred embodiment of the electric spray gun for drilling holes for preventing and controlling garden tree trunk-boring pests provided by the present invention is as follows: Figure 1-5As shown: an electric spray gun for drilling holes for preventing and controlling garden tree trunk-boring pests, comprising an electric pistol body 11, a liquid medicine bottle assembly 12, and a medicine gun assembly 13. The hand-held handle of the electric pistol body 11 is provided with a power button 14, and a battery cavity is provided at the bottom end of the hand-held handle of the electric pistol body 11. The battery cavity is adapted to be equipped with a battery box 15, and the battery box 15 is equipped with a power battery block. A card cover 18 is provided at the rear end of the electric pistol body 11, and a circuit board 19 is built in the card cover 18. The circuit board 19 is electrically connected to the power button 14 and the power battery block. The hand-held handle of the electric pistol body 11 is also provided with a trigger drive button 16, and a trigger guard 17 is fixedly provided on the electric pistol body 11;

[0028] In this embodiment, the trigger driving button 16 is operated to drive the threaded drill bit 131 to drill holes in trees, thereby achieving precise pesticide application. In addition, the circuit board 19 is provided with a current protection device to ensure that equipment damage or safety accidents caused by abnormal battery voltage are avoided during use. The overall design of the electric pesticide spraying gun is easy to operate, improves work efficiency, and reduces the use of chemical pesticides and reduces the impact on the environment.

[0029] Example 2

[0030] See also Figure 1-Figure 5 , and on the basis of Example 1, it is further obtained that: a liquid medicine flow channel 121 is opened at the front end of the electric pistol body 11, the liquid medicine bottle assembly 12 includes a liquid medicine bottle 123, and the liquid medicine bottle 123 is internally installed with a micro electric pump 126 connected to the circuit board 19 signal;

[0031] One end of the liquid medicine flow channel 121 is connected with a threaded nozzle 122, which is threadedly connected to the liquid medicine bottle 123. A one-way check valve 124 is fixedly arranged at the port of the liquid medicine bottle 123. The bottom of the one-way check valve 124 is connected with a liquid guide tube 125 connected to a micro electric pump 126, and the top of the one-way check valve 124 is connected with a liquid guide tube 2 127, which is made of a telescopic elastic material.

[0032] In this embodiment, the well-designed liquid medicine flow channel 121 ensures that the liquid medicine can be precisely controlled by the micro-electric pump 126, and then the liquid medicine can be quantitatively transported through the liquid guide tube. This design significantly improves the accuracy of drug application, so that the drug can be more accurately delivered to the target location. At the same time, the liquid guide tube 127 made of a telescopic elastic material can freely expand and contract according to the movement of the drilling needle 133, thereby adaptively expanding and contracting to ensure that the liquid medicine can be directly injected into the worm tunnel without leakage. This design not only improves the efficiency of drug application, but also ensures the effective use of the liquid medicine and avoids unnecessary waste.

[0033] In addition, the design of the one-way check valve 124 effectively prevents the backflow of the liquid medicine, ensuring the smooth progress of the drug application process. This design not only avoids drug waste, but also enhances the practicality of the entire device. The signal of the electric pump 126 is connected to the circuit board 19, so that the entire drug application process can be automatically controlled. This automatic control function further improves the convenience of operation, and also improves the efficiency and accuracy of drug application. Through this automatic control, the operator can complete the drug application task more easily, while ensuring the stability and reliability of the drug application process.

[0034] The medicine gun assembly 13 includes a threaded drill bit 131, the end of the threaded drill bit 131 is a flat end body 132, the threaded drill bit 131 is connected with the other end of the medicine liquid flow channel 121, the threaded drill bit 131 is equipped with a drilling needle 133, the end of the drilling needle 133 is a pointed end body 134, the drilling needle 133 is equipped with a medicine liquid cavity 135, and the medicine liquid cavity 135 is connected with the second catheter 127;

[0035] A convex plug 136 is integrally connected to the middle position of the drilling needle 133, and the outer wall of the convex plug 136 is in sliding contact with the inner cavity of the threaded drill bit 131. The outer wall of the drilling needle 133 is sleeved with a return spring 137, one end of the return spring 137 is fixedly connected to the convex plug 136, and the other end of the return spring 137 is fixedly connected to the threaded drill bit 131.

[0036] In this embodiment, the start and stop of the micro-electric pump 126 is controlled by the circuit board 19, which ensures the accurate delivery of the liquid medicine and prevents the liquid medicine from flowing back. When the operator pulls the trigger driving button 16, the micro-electric pump 126 starts, and the liquid medicine passes through the one-way check valve 124, the first liquid guide tube 125 and the second liquid guide tube 127 from the liquid medicine bottle 123, and finally is injected into the trunk through the threaded drill bit 131 and the drilling needle 133. In this process, the convex plug 136, under the action of the reset compression spring 137, allows the drilling needle 133 to be freely retracted, ensuring the stable advancement of the drill bit, while reducing the displacement of the drilling needle 133 caused by external force, effectively improving the accuracy of drug application.

[0037] It is explained here that, firstly, since the electric pistol body 11 is an existing public technology, its specific structure will not be described in detail in this application. The working principle of the electric pistol body 11 is similar to that of an electric drill, which uses the motor rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor to perform magnetic field cutting and work operation, and drives the working device through the transmission mechanism to drive the gear to increase the power of the drill bit, so that the tip body 134 on the drilling needle 133 built into the threaded drill bit 131 scrapes the surface of the object and better penetrates the object;

[0038] When using it, the specific steps are as follows:

[0039] Step 1: First, the tip 134 of the drilling needle 133 built in the threaded drill bit 131 is placed close to the outer skin of the tree trunk between 10 cm and 30 cm below the defecation opening of the garden tree trunk pests;

[0040] Step 2, turn on the power button 14, press the trigger driving button 16 (the trigger driving button 16 is divided into two buttons, the upper button is pressed at this time), so that the tip body 134 on the drilling needle 133 drills a hole, the maximum drilling depth reaches 15 cm, and the hole size is 1.5 mm;

[0041] Step 3, when the drilling needle 133 reaches the loose larval worm tunnel, the lower button is manually turned on, and the micro-electric pump 126 in the liquid bottle 123 starts to start, and the control liquid will pass through the micro-electric pump 126 along the liquid guide tube 125, the one-way check valve 124, and the liquid guide tube 2 127 to the liquid chamber 135 provided in the drilling needle 133, and be injected into the larval worm tunnel from the tip body 134. Special note: Due to the different densities between the wood of garden trees and the larval worm tunnel filled with loose excrement eaten by the stem-boring larvae, the former has a hard texture and a large density, while the latter is loose and has a small density. The load pressure when the drilling needle 133 passes through is different, that is, the drilling needle 133 obviously feels different when passing through, and the pressure of the control liquid will continuously inject the liquid into the larval worm tunnel;

[0042] Step 4, continue to inject the control liquid through the drilling needle 133 until the control liquid seeps out from the larval excretion holes. At this point, the process steps of injecting the control liquid for trunk-boring pests are completed.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
