[0002] In fruit tree management, fruit tree trunk-boring pests have always been one of the key factors affecting fruit tree growth and yield. Common fruit tree trunk-boring pests include longhorn beetles, bark beetles, wood borers, etc. These pests eat the wood of fruit trees, causing nutrient loss and growth stunting. They can cause irreversible damage to the internal structure of the trunk, resulting in damage to the health of the tree, affecting fruit yield and quality. When they develop to a certain extent in the trunk, the entire trunk will die, which is directly related to the overall life of the fruit tree.

[0003] However, for fruit tree trunk borers, the main prevention and control method is to detect them early and inject them with a syringe. The injection head is manually inserted into the location of the trunk borers, and then the piston rod is pushed to squeeze out the agent.

[0042] The specific implementation process is as follows:

[0043] When using the device of the present invention, the length of the connecting member 4 is adjusted, and the clamping device 5 is fixed on the tree trunk so that the entire device is fixed. The third motor 72 is started, so that the installation cylinder 21 drives the guide member 3 to move forward into the wormhole, and the second motor 61 is started. The active bevel gear 65 drives the second screw rod 62 to rotate, so that the second rack 82 drives the semi-conical guide member 3 to open outward. At the same time, the injection barrel 22 moves the injection head 25 forward to the tip of the guide member 3; then the first straight gear 66 drives the first rack 68 to move, so that the piston rod 23 squeezes out the medicine; similarly, the motor is reversed, and the semi-conical guide member 3 gathers inward. At the same time, the injection barrel 22 retreats the injection head 25 to the accommodating cavity of the guide member 3, and the piston rod 23 slides in the direction away from the injection head 25 to draw the medicine in the medicine box 24 into the injection barrel 22.

[0044] Among them, the two semi-conical guide members 3 form a accommodating chamber with a variable area size, and the injection head 25 of the syringe is located in the accommodating chamber. When the two guide members 3 are gathered together, they form a cone, which is convenient for the guide members 3 to be inserted into the wormhole. When the two semi-conical guide members 3 are opened, the injection head 25 can be extended and spray the medicine into the wormhole; the driving device in the installation tube 21 drives the injection tube 22 and the piston rod 23 to slide, so that when the two semi-conical guide members 3 are opened, the injection head 25 moves forward and reaches the tip of the semi-conical guide member 3. The driving device drives the piston rod 23 to slide in the direction of the injection head 25 to spray the medicine into the wormhole; after the spraying is completed, the driving device drives the injection tube 22 to slide in the opposite direction, and the injection tube 22 drives the injection head 25 to retreat. At the same time, the second rack 82 drives the second spur gear 81 to rotate, and the second spur gear 81 drives the semi-conical guide member 3 to rotate, so that the two semi-conical guide members 3 are gathered together to form a conical accommodating chamber to protect the injection head 25 from being damaged or contaminated with sawdust. In this way, the automatic injection and exit procedures can be continuously realized, the prevention and control efficiency is increased, and the labor cost is reduced; and by setting the semi-conical guide member 3, the injection head 25 can be protected to prevent the injection head 25 from being blocked or damaged; by setting the guide members 3 with different tapers, the injection head 25 can be sent to positions of different depths, and the injection can be injected into the deep position of the tree trunk to increase the prevention and control effect; the injection barrel 22 is connected to the second slide rail 221, and the installation barrel 21 is connected to the second slide groove 212, the second slide rail 221 is slidably connected in the second slide groove 212, and the cross-sectional shapes of the second slide rail 221 and the second slide groove 212 are both "convex" shapes, which can play a guiding and limiting role, and prevent the injection barrel 22 from rotating under the action of the second wire seat 63, and further increase the stability of the frame structure;

[0045] The nut 55 is turned counterclockwise to move it in a direction away from the second clamping plate 56. Under the action of the rebound force of the spring 53, the second clamping plate 56 moves in a direction away from the first clamping plate 52, so that the distance between the first clamping plate 52 and the second clamping plate 56 away from the U-shaped frame 51 becomes larger, and the distance is adjusted according to the diameter of the tree trunk. Similarly, the nut 55 is turned clockwise to reduce the distance between the first clamping plate 52 and the second clamping plate 56 away from the U-shaped frame 51. In this way, the clamping degree can be adjusted as needed, and the threaded connection between the nut 55 and the screw rod 54 can provide a clamping force on the tree trunk, increasing the stability of the entire device. By arranging the spring 53 between the first clamping plate 52 and the second clamping plate 56, the rebound force of the spring 53 makes it easy to remove the clamping plate from the tree trunk. One end of the clamping plate away from the screw rod 54 is set as an arc plate 521, which can adapt to the shape of the tree trunk to increase the stability of the device, and a soft support pad is connected to the inner side of the arc plate 521 to avoid damaging the tree trunk.

[0046] The connecting member 4 is composed of a first motor 42, a fixed sleeve 45, a telescopic sleeve 44, a first screw rod 41 and a first wire seat 43. The connection is stable, the operation is convenient, and the labor cost is further reduced. Specifically, the first motor 42 drives the first screw rod 41 to rotate, the first screw rod 41 drives the first wire seat 43 to slide, and the first wire seat 43 drives the telescopic sleeve 44 to slide along the axial direction of the fixed sleeve 45 to achieve the extension and shortening of the connecting member 4.
