[0019] Preferably, the inside of the accommodating cylinder 11 in the application is provided with a first sliding hole 13 and a second sliding hole 12. By providing two sliding holes, it is ensured that, during use, since trees are divided by a diameter of 10 cm, trees larger than 10 cm and smaller than 10 cm, and every increase of 1 cm in diameter, the amount of the increased liquid medicine 9 required is different, so that when in the inside of the first sliding hole 13, it is suitable for small diameter trees, and when the larger diameter trees are clamped, the flange of the sliding column 56 will enter the inside of the second sliding hole 12, realizing the control of the amount of liquid medicine 9. The first sliding hole 13 is located at one end close to the clamping head 5, the diameter of the second sliding hole 12 is larger than that of the first sliding hole 13, and the end of the sliding column 56 is provided with a ring flange close to the inner wall of the first sliding hole 13, so that when in the inside of the first sliding hole 13, the ring flange can seal the first sliding hole 13, ensuring that the amount of liquid medicine 9 can be controlled. The second sliding hole 12 is slidably connected with a plug 6, and the plug 6 and the bottom of the second sliding hole 12 are provided with a thrust spring 15. The plug 6 is abutted against the ring flange under the action of the thrust spring 15, ensuring the sealing of the other side of the plug 6 at this time, and at the same time, the sliding column 56 pushes the plug 6 to slide in the inside of the second sliding hole 12 after it is separated from the first sliding hole 13. At this time, the tree is just more than 10 cm in diameter, so as to control the increase of the amount of liquid medicine 9. At the same time, the storage space is the space formed between the sliding column 56 and the first sliding hole 13 and the second sliding hole 12. The inner wall of the first sliding hole 13 and the outer wall of the ring flange are close to each other, ensuring the sealing effect of various sliding parts.

[0020] In addition, the second sliding hole 12 of the application is slidably connected with a second piston 7, the outer wall of the second piston 7 is close to the outer wall of the second sliding hole 12, and the inner hole diameter corresponds to the diameter of the first sliding hole 13, ensuring that the second piston 7 blocks the second sliding hole 12, and at the same time, when the first piston 8 is separated from the first sliding hole, the first piston 8 can be clamped into the second piston 7, forming a blocking and pushing process for the gap between the sliding column 56 and the second sliding hole 12. A certain gap is provided between the second piston 7 and the sliding column 56, so that the ring flange of the sliding column 56 can slide in the inside of the second piston 7 during use, preventing the sliding column 56 from moving with the second piston 7. When the first piston 8 slides to be close to the second piston 7, the first piston 8 and the second piston 7 cooperate to block the second sliding hole 12. At the same time, a sealing hole 16 is provided at the end of the first sliding hole 13 and close to the outer wall of the sliding column 56, preventing the liquid medicine 9 from leaking from the gap between the sliding column 56 and the first sliding hole 13, affecting the amount of liquid medicine 9.

[0021] Referring to Figures 1-5 , Figure 8 and Figure 9Further, the inner wall of the first sliding hole 13 is provided with a sliding groove, the first ring body 81 on the first piston 8 is provided with a protrusion 82 matched with the sliding groove, so that the first ring body 81 can tightly seal the whole first sliding hole 13, the side wall of the second piston 7 is provided with a groove 71 matched with the protrusion 82, the protrusion 82 and the groove 71 are arranged, so that the ring protrusion can pass through the second ring body 72 of the second piston 7 at this time, and the second piston 7 is prevented from interfering with the ring protrusion, the side wall of one end of the first sliding hole 13 close to the clamping head 5 is provided with a control hole 14, the control hole 14 is connected with the positive pressure or negative pressure fluid, the first piston 8 and the second piston 7 are driven to reciprocate by the fluid, when the medicine liquid 9 in the medicine storage space is full, the high-pressure fluid (which can be liquid or gas) in the control hole 14 at this time pushes the first piston 8 to slide in the first sliding hole 13, the medicine liquid 9 in the medicine storage space is directly pushed into the medicine outlet 55 through the communication hole 57, and is injected into the tree through the injection head 4 in the insertion hole 51, and the process of injection prevention and treatment is completed.

[0022] Better, the driving member is a bidirectional screw rod 2, the clamping head 5 is provided with a threaded hole 53, the two clamping heads 5 are respectively screwed with two threaded segments of the bidirectional screw rod 2, the main frame body 1 is fixedly provided with a rotating motor 3 for driving the bidirectional screw rod 2 to rotate, so that the arc-shaped clamping portions 52 of the two clamping heads 5 can be driven by the rotating motor 3 to clamp the tree, and a torsion bearing can be arranged between the bidirectional screw rod 2 and the driving shaft of the rotating motor, so that the bidirectional screw rod 2 can stop rotating after the clamping head 5 clamps the tree.

[0023] Further, the top of the clamping head 5 is provided with a medicine injection opening 54 connected with the medicine liquid channel 58, the medicine injection opening 54 is connected with a medicine liquid supply mechanism, so that the medicine liquid 9 is supplied into the medicine storage space, the medicine outlet 55 is connected with the injection head 4 through a hose, so that the movement of the clamping head 5 is prevented, the clamping head 5 comprises the arc-shaped clamping portion 52, the side wall of the arc-shaped clamping portion 52 is provided with the insertion hole 51 inclined by 45° from outside to inside, after clamping, the injection head 4 is pulled out, then the insertion hole 51 is directly opposite the tree for punching, so that the punching angle is ensured, and after the punching is completed, the injection head 4 is directly inserted, so that the injection of the medicine liquid 9 in the interior is completed, and the insertion hole 51 can also be directly opposite the punched tree for clamping after the punching, so that the injection head 4 is inserted into the insertion hole 51 and the punched hole.

[0024] In the embodiment, the combination of the injection head 4 and the clamping head 5 can be used for injection prevention and treatment of the tree, and the injection head 4 can be directly inserted into the insertion hole 51 and the punched hole of the tree, so that the medicine liquid 9 in the interior is injected into the tree. Figures 1-9In use, the device can be directly installed on a mobile trolley or directly installed on a handheld device. When the corresponding tree needs to be injected, when the diameter of the tree is less than 10 cm, the ring protrusion at the end of the sliding column 56 is inside the first sliding hole 13 when the clamping head 5 clamps the tree. After clamping is completed, the actual space required for the liquid medicine 9 is the storage space between the inside of the ring protrusion, the outside of the sliding column 56, and the inside of the sliding hole. At this time, when the material is pushed, the first piston 8 directly pushes the liquid in the space into the injection head 4 under the action of the positive pressure fluid, and no longer moves under the limitation of the inner wall of the ring protrusion, completing the high-pressure injection process into the tree. At this time, even if the liquid medicine 9 leaks to other positions from the chute, since the other positions are also filled with liquid medicine 9, under the action of the first piston 8, the liquid medicine 9 in the corresponding area can only be pressed into the inside of the injection head 4, and when the reset, the liquid medicine 9 will flow back to the original position, which will not affect the use of the clamping head 5 and the liquid medicine 9.

[0025] When the diameter of the tree is greater than 10 cm, the ring protrusion of the sliding column 56 will be separated from the inside of the first sliding hole 13 and enter the second sliding hole 12. At this time, the sliding column 56 abuts against the blocking head 6, which compresses the push spring 15 under the pushing action of the sliding column 56. At this time, the increase in unit displacement of the liquid medicine 9 changes, adapting to the demand for liquid medicine 9 for larger trees. When the material is pushed, the first piston 8 moves to abut against the second piston 7. In order to ensure the integrity of the first piston 8 and the second piston 7, the first piston 8 and the second piston 7 can be made of materials that ensure the adsorption effect between them. The liquid medicine 9 located inside the first sliding hole 13 and the second sliding hole 12 is directly pressed into the injection head 4 by the synchronous movement of the first piston 8 and the second piston 7, completing the effect of injecting the tree. When resetting, the control hole 14 extracts negative pressure inside, and the first piston 8 and the second piston 7 reset to the initial position under the action of negative pressure.

[0026] In summary, the present application provides a forest pest control device, comprising: a main frame, the top of which is slidingly connected with two symmetrically arranged clamping heads for clamping trees, the two clamping heads clamp the position of the tree where drilling and liquid injection are needed, thereby automatically detecting the diameter of the tree, reducing the operation steps when detecting the diameter of the tree manually with a tape measure, the top of the main frame is provided with a driving member for driving the two clamping heads to move towards each other, the two clamping heads are driven by the driving member to clamp the tree; a containing cylinder containing liquid medicine is arranged outside the main frame, by arranging the containing cylinder, the size of the medicine storage space can be controlled by sliding the clamping head, the outside of the clamping head is slidingly connected with a sliding column inside the containing cylinder, the sliding column slidingly controls the medicine storage space inside the containing cylinder, ensuring that different amounts of liquid medicine are injected into trees of different sizes, a liquid medicine channel is arranged inside the clamping head, an injection head is arranged at the front end of the clamping head, the liquid medicine is injected into the inside of the tree through the injection head, the medicine outlet of the liquid medicine channel is connected with the inlet of the injection head, the end wall of the sliding column is provided with a communication hole communicating the liquid medicine channel and the medicine storage space, by arranging the communication hole, the medicine storage space and the liquid medicine channel are communicated, further ensuring that the injection head is supplied with liquid medicine, a first piston is slidingly arranged on the side wall of the medicine storage space, the first piston pushes the liquid medicine to be injected into the inside of the tree through the injection head, thereby realizing the quantitative supply of liquid medicine to the injection head, in summary, the technical effect of the present application is that by arranging a clamping head that automatically measures the diameter of the tree, when the clamping head clamps the tree, a corresponding amount of liquid medicine is automatically matched according to the position of the clamping head, and then the corresponding amount of liquid medicine is injected into the inside of the tree, thereby automatically measuring and quantitatively supplying liquid medicine, reducing the error and process of manual control, and simplifying the steps of injection control.
