Description

Technical Field

[0001] This invention relates to the field of eucalyptus maintenance technology, and in particular to an injection device for controlling eucalyptus pests. Background Technology

[0002] By directly injecting pesticides or nutrient solutions into eucalyptus trees, the pesticides are quickly absorbed and utilized by the tree's internal sieve tubes and xylem vessels, effectively killing insects inside the trunk with through-holes or blind holes. This not only saves on and controls pesticide use but also improves the tree's survival rate, helping to restore normal tree growth, control pests, and promote healthy growth.

[0003] Existing methods for injecting tree nutrients or medications typically involve inserting a needle into the trunk. For example, the invention patent with application number CN202410281751.9 discloses a cross-shaped eucalyptus application front claw fixing and control device. This device can fix the eucalyptus tree during injection, preventing tree movement and ensuring accurate application. While the needle injection method allows for stable application with the front claw fixing, the method of inserting the needle into the trunk is prone to problems such as needle blockage and difficulty in clearing blind holes, preventing the tree from absorbing the injected nutrient solution or medication. Furthermore, both the injection tube and syringe are disposable, resulting in significant pollution and waste. Summary of the Invention

[0004] This application provides a eucalyptus pest control liquid injection device. The drilling mechanism allows for easy drilling of holes in the trees, while the injection mechanism allows for easy injection of nutrient solution or pesticide into the trees. The integrated design greatly increases injection efficiency.

[0005] This application provides a punching and injection device, including a drug storage housing and a punching and injection device installed in the housing. The injection device includes a motor frame, a motor reduction gear, a transmission screw, and a movable piston. The punching device includes a drive motor, a drill chuck connected to the drive motor, and a special drill bit fixed to the drill chuck.

[0006] The injection mechanism includes a micro drive motor, a transmission screw, and a movable piston. The transmission shaft of the micro drive motor is fixedly connected to the transmission screw. The transmission screw is connected to the output shaft of the motor via a reduction gear. The transmission screw is a ball screw that engages with a threaded connection in the center of the piston. The outer edge of the piston is smoothly connected to the inner wall of the rotating housing.

[0007] The drilling mechanism includes a drive motor fixed in the middle of the drug storage shell, a drill chuck, and a specially designed drill bit. The drill chuck is a gear-key type; the drill bit has a liquid outlet channel in the middle and a liquid outlet hole on the side of the front end.

[0008] Preferably, the drive motor is a DC geared motor with an encoder, which can effectively control the stopping and forward / reverse rotation of the mechanism.

[0009] Preferably, the injection mechanism is fixed to one end of the drug storage shell to ensure the stability of the drive.

[0010] Preferably, the injection mechanism is equipped with a miniature drive motor, a reduction gear, a transmission screw, and a movable piston.

[0011] Preferably, the movable piston consists of two rigid silicone round pads and a connecting rod.

[0012] Preferably, the movable piston is fed by a ball screw.

[0013] Preferably, the housing is provided with a drilling mechanism, and the drive motor is fixed to the middle of the housing by a motor mount.

[0014] Preferably, the drill bit has a fluid flow channel in the middle and a fluid outlet hole on the front side.

[0015] Preferably, the liquid storage shell is made of high-hardness composite material; the drill bit is made of high-strength aluminum alloy.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: In this invention, a drive motor rotates a specially designed drill bit, achieving high-speed rotation to cut and drill holes in the tree. When the drilling reaches a predetermined depth, the drill bit can be stopped or reversed to remove sawdust. Simultaneously, a micro-drive motor in the injection mechanism starts working, driving a transmission screw. This causes a movable piston, engaged with the screw, to move at a constant speed, compressing the internal space of the medicine storage shell and forcing the medicine into the specially designed drill bit. The medicine is then discharged from the outlet hole on the side of the drill bit's front end, thus injecting the medicine into the eucalyptus tree. This injection of nutrient solution or medicine allows it to be rapidly absorbed and utilized by the sieve tubes and vascular bundles inside the eucalyptus tree. It has a significant effect on pests that infest trees with through-holes or blind holes, killing pests, helping the tree recover its normal growth, promoting eucalyptus tree recovery, and increasing the tree's survival rate.

[0017] In this invention, the high-strength drill bit is fixedly connected by a suitable drill bit chuck. The drill bit chuck adopts a three-jaw chuck structure inside, which can effectively prevent the drill bit from coming loose during the drilling process and causing danger.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] This invention is combined with the appendix Figure 1-4 For the purposes of this example: A eucalyptus pest control liquid injection device includes a drug storage shell 1, a punching mechanism 2, and a servo injection mechanism 3.

[0027] The front end of the drilling mechanism 2 is the working end of the drill bit, which includes a second drive motor 21 and a drill chuck 23 fixedly connected to the second drive motor; a drilling drill bit 24 fixed on the drill chuck, the drill rod section of the drill bit passes through the round hole at the front end of the outer shell and the center of one end of the movable piston, and the two round holes are equipped with a rotating shaft sealing ring to form a closed liquid storage space.

[0028] The injection mechanism 3 includes a first drive motor 31 fixed to one end of the drug storage shell, a reduction gear 33, and a ball screw 34 connected to the motor output shaft.

[0029] like Figure 1 As shown, the exterior of the drug storage shell 1 adopts a cylindrical design.

[0030] With this configuration, the entire punching and liquid delivery device is fixed by the cooperation of the outer shell 1 and the external mechanical clamp, making it easy to complete the punching and injection operation under the external drive device.

[0031] like Figure 2 As shown, the second drive motor 21 is fixed to the middle section inside the outer casing by the second drive motor base 22.

[0032] With this configuration, the cooperation between the second drive motor base 22 and the medicine storage shell 1 can prevent the motor shaft and the drill bit 24 from being concentric, thus avoiding the shaking of the drill bit 24 and affecting the drilling effect.

[0033] like Figure 2 As shown, the first drive motor 31 is connected to the tail end of the medicine storage shell through the first drive motor frame 32.

[0034] With this configuration, the second drive motor base 22 can cooperate with the drug storage shell 1 to achieve centering and fixation of the injection mechanism 2, ensuring stable operation while maintaining the positional accuracy of the mechanism.

[0035] like Figure 3 As shown, the ball screw 34 and the movable piston 35 achieve smooth piston movement through the threaded engagement.

[0036] This configuration ensures that the movable piston 35 moves smoothly on the lead screw 34, allowing the liquid medicine to be discharged stably and evenly from the outlet hole at the front end of the drill bit. Furthermore, when replenishment of the liquid medicine is required, the front end of the drill bit 24 can be inserted into the liquid medicine, and the first drive motor 31 will drive the movable piston 35 to move rapidly into the housing, drawing the liquid medicine into the storage space through the resulting negative pressure.

[0037] like Figure 4 As shown, the drilling bit 24 is fixed by the drill bit clamp 23.

[0038] This design facilitates the installation, disassembly, and maintenance of drill bits.

[0039] In use, the operator can install the device on an automated device such as a robotic arm, and use clamps to secure the entire device by clamping the drug storage shell 1. When the drilling point is determined and drilling begins, the second drive motor 21 is started, and the motor output shaft begins to drive the drill bit to move at high speed to drill holes in the eucalyptus tree, completing the opening operation for eucalyptus sap infusion. After drilling is completed, the second drive motor 21 is reversed or stopped, and the drill bit is pushed out to remove the sawdust. Then, the first drive motor 31 is started, and the motor output shaft controls the ball screw to rotate, driving the movable piston 35 to compress the drug storage space, causing the sap to flow into the flow channel inside the drill bit 24 and be discharged from the side outlet, realizing integrated drilling and injection operation.
