Description

Technical Field

[0001] The invention relates to the technical field of eucalyptus maintenance, and in particular to a eucalyptus pest control liquid injection device. Background Art

[0002] By directly injecting tree pest control liquid or nutrient solution into eucalyptus, it can be quickly absorbed and utilized by the internal sieve tubes and ducts of eucalyptus, and has excellent effect on killing internal pests in tree trunks with through holes or blind holes. In helping to restore the normal growth of trees, killing pests and promoting the recovery of tree growth, it can not only save and control the use of liquid, but also improve the survival rate of trees.

[0003] The existing method of injecting tree nutrient solution or liquid medicine into trees usually uses a needle to penetrate the tree trunk. For example, the invention patent with application number CN202410281751.9 discloses a cross-type eucalyptus spraying front paw fixation and its control device. By fixing the control device, the eucalyptus can be fixed when injecting the medicine to prevent the tree from shaking and causing the spraying position to deviate, thereby improving the accuracy of spraying. It adopts the method of needle injection, and can smoothly apply the medicine under the fixation of the front paw. However, the method of piercing the tree trunk with a needle is prone to problems such as needle clogging and difficulty in handling blind holes, resulting in the tree being unable to absorb the injected tree nutrient solution or liquid medicine. At the same time, the injection belt and syringe are disposable and will be thrown away after use, causing serious pollution and waste. Summary of the invention

The integrated design can greatly increase the injection efficiency.

[0005] The example of the present application provides a perforating injection device, including a medicine storage shell, a perforating injection device installed in the shell, the injection device including a motor frame, a motor reduction gear, a transmission screw and a movable piston; the perforating device includes a driving motor, a drill chuck connected to the driving motor, and a special drill bit fixed on the drill chuck.

[0006] The injection mechanism includes a micro-drive motor, a transmission screw and a movable piston. The micro-drive motor transmission shaft is fixedly connected to the transmission screw, and the transmission screw is connected to the motor output shaft through a reduction gear. The transmission screw adopts a ball screw and is spirally engaged with a thread set in the center of the piston. The outer edge of the piston is smoothly connected to the inner wall of the rotating shell.

[0007] The drilling mechanism includes a driving motor fixed in the middle of the medicine storage shell, a drill chuck and a special drill. The drill chuck structure is a gear key type drill chuck; a liquid outlet channel is provided in the middle of the drill bit, and a liquid outlet hole is provided on the side of the front end of the drill bit.

[0008] Preferably, the driving motor adopts a DC reduction motor with an encoder, which can effectively control the shutdown and forward and reverse rotation of the mechanism.

[0016] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: In the present invention, a driving motor is used to drive a special drill bit to rotate, so as to achieve a high-speed rotation effect of the drill bit, thereby realizing cutting and drilling of trees. When the drilling reaches a predetermined depth, the drill bit can be stopped or reversed to remove wood chips; at the same time, the micro-driving motor in the injection mechanism starts to work, driving the transmission screw rod, so that the movable piston screwed with the screw rod moves at a uniform speed, compressing the internal space of the medicine storage outer shell, squeezing the medicine liquid into the special drill bit, and making it discharge from the liquid outlet hole on the side of the front end of the drill bit, thereby realizing the drilling and injection of eucalyptus. Such injection of nutrient solution or medicine liquid can enable it to be quickly absorbed and utilized by the sieve tube and conduit inside the eucalyptus. It has a significant effect on trunk-resident pests with through holes or blind holes, can kill pests, help restore the normal growth of trees, promote the recovery of eucalyptus, and improve the survival rate of trees.

[0017] In the present invention, the high-strength drill bit is fixedly connected by an adapted drill chuck, and a three-jaw chuck structure is adopted inside the drill chuck, which can effectively prevent the drill bit from loosening during the drilling process and causing danger.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The present invention is combined with the Figure 1-4 To provide instructions for this example: A eucalyptus pest control liquid medicine injection device comprises a medicine storage shell 1, a punching mechanism 2, and a servo injection mechanism 3.

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

[0028] The injection mechanism 3 comprises a first driving motor 31 fixed to one end of the medicine storage housing, a reduction gear 33, and a ball screw 34 connected to the output shaft of the motor.

[0029] like Figure 1 As shown, the exterior of the medicine storage housing 1 is cylindrical in design.

[0030] With such arrangement, the outer shell 1 cooperates with the external mechanical fixture to fix the entire perforating and liquid feeding device, so as to facilitate the perforating and injection operation under the external driving device.

[0031] like Figure 2 As shown, the second drive motor 21 is fixed to the middle section inside the outer shell by means of a second drive motor seat 22 .

[0032] With such arrangement, the cooperation between the second driving motor base 22 and the medicine storage outer shell 1 can avoid the concentricity between the motor shaft and the drill bit 24, thereby 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 rear end of the medicine storage housing through the first drive motor frame 32.

[0034] With such arrangement, the second drive motor base 22 cooperates with the medicine storage housing 1 to achieve centering and fixation of the injection mechanism 2, thereby ensuring stable operation under the premise of ensuring the position accuracy of the mechanism.

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

[0036] Such arrangement enables the movable piston 35 to maintain stable movement on the screw rod 34, so that the liquid medicine can be discharged stably and evenly from the liquid outlet hole at the front end of the drill bit. In addition, when the liquid medicine needs to be replenished, the front end of the drill bit 24 can be inserted into the liquid medicine, and the first drive motor 31 can be used to drive the movable piston 35 to move rapidly into the housing, and the liquid medicine can be sucked into the medicine storage space by the negative pressure formed.

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

[0038] Such arrangement makes it easy to install, disassemble and maintain the drill bit.

[0039] When in use, the operator can install the device on an automated device such as a robotic arm, and clamp the medicine storage outer shell 1 with a clamp to fix the entire device. When the drilling point is determined and drilling begins, the second drive motor 21 is started, and the motor output shaft starts to drive the drill bit to move at high speed to perform drilling operations on the eucalyptus, completing the opening operation for eucalyptus infusion. After the drilling is completed, the second drive motor 21 is reversed or stopped, and the drill bit is pushed out. After the sawdust is exhausted, the first drive motor 31 is started, and the motor output shaft controls the ball screw to start rotating, driving the movable piston 35 to compress the medicine storage space so that the liquid medicine flows into the flow channel inside the drill bit 24 and is discharged from the side liquid outlet, thereby realizing an integrated drilling and injection operation.
