Description

Technical Field

[0001] The present invention relates to the field of agriculture, and particularly to a punching and medicine-injecting device for preventing and controlling agricultural pests and diseases. Background Art

[0002] Punching and medicine-injecting for preventing and controlling agricultural pests and diseases is a method of preventing and controlling pests and diseases by drilling holes in the tree trunks and injecting medicines. This method utilizes the transpiration of the trees themselves to transport the liquid medicine to all parts of the trees, thereby achieving the effect of preventing and controlling pests and diseases. Use a steel drill to vertically drill a hole 3 to 4 cm deep into the xylem at the horizontal root base of the damaged tree. Drill 2 to 4 holes for each tree, and the number of holes can be appropriately increased for larger trees. Inject different amounts of liquid medicine according to the diameters of different trees. For example: for a diameter of 10 to 15 cm, 5 to 7 ml of monocrotophos stock solution can be injected; for a diameter of 11 to 20 cm, 7 to 10 ml can be injected; for a diameter of 21 to 30 cm, 10 to 15 ml can be injected. Punching and medicine-injecting for preventing and controlling trunk borers is an effective, labor-saving, time-saving and cost-saving technology. At the same time, it also effectively prevents and controls foliage pests, has no pollution to the environment, and causes very slight phytotoxicity to the trees.

[0003] Punching and medicine-injecting is very effective in the prevention and control of agricultural pests and diseases. However, when performing the medicine-injecting operation, multiple operations such as drilling, cleaning, and medicating need to be carried out at the root and stem parts of the crops. The operation process is cumbersome, and there is a lack of a simple and fast punching and medicine-injecting device that can perform all operations within one drilling cycle. Summary of the Invention

[0005] (II) Technical Solution To solve the above technical problems, the present invention provides a punching and medicine-injecting device for preventing and controlling agricultural pests and diseases, including a fixing plate and a limiting plate for clamping crops. The fixing plate is of a fixed design, and the distance between the limiting plate and the fixing plate is adjusted by a distance adjusting mechanism. The direction adjusting mechanism includes convex plates arranged at intervals on the limiting plate. A direction adjusting shaft driven to rotate by a direction adjusting motor penetrates through the convex plates. An adjusting plate parallel to the opening of the limiting plate is sleeved outside the direction adjusting shaft, and a brush ring member is arranged inside the adjusting plate. The advancing mechanism is installed at the lower part of the adjusting plate and is used to control the punching mechanism to approach or move away from the crops. The punching mechanism includes a driving device. A gear box is installed at the output end of the driving device. A drilling gear meshing and transmitting is arranged inside the gear box. A bearing member on the drilling gear is connected to a hollow drill rod, and the combination of the two is a through structure. A hollow medicine injection rod is clamped inside the drill pipe. The liquid supply mechanism includes a liquid inlet end seat installed at the other end of the drilling gear. A three-way pipe is installed above the liquid inlet end seat, and the three-way pipe is connected to a liquid medicine tank and a cooling water tank through branch pipes.

[0006] Preferably, the distance adjustment mechanism includes a distance adjustment frame installed on the fixed plate. A distance adjustment screw is installed in the middle of the distance adjustment frame. Distance adjustment support rods are arranged on both sides of the distance adjustment screw.

[0009] Preferably, the propulsion mechanism includes a propulsion frame that rotates synchronously with the direction adjustment plate. A main rod is installed in the middle of the propulsion frame. Guide rods are arranged on both sides of the main rod. The main rod is controlled by a propulsion motor to drive rotation, and a propulsion sliding seat that slides along the guide rods is sleeved on the outer wall. A support plate platform for lifting is installed above the propulsion sliding seat.

[0010] Preferably, the driving device, the liquid medicine tank, and the cooling water tank are all installed on the support plate platform, and the three are displaced synchronously with the support plate platform.

[0011] Preferably, a gear set is built in the gearbox. The drilling gear is an output gear. The combination of the drilling gear, the bearing part, and the drill pipe is on the same axis, and the three rotate along the axis of the liquid inlet end seat.

[0012] Preferably, a medium transmission channel is left at the axis of the combination of the drilling gear, the medicine injection rod, and the liquid inlet end seat. The combined structure of the liquid inlet end seat and the medicine injection rod is used for supplying water and medicine.

[0013] Preferably, the medicine injection rod is installed through the axis of the drill pipe. The drill pipe has a "twisted" structure, and chip discharge grooves are opened on the outer wall.

[0019] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0020] As Figure 1-6As shown in the figure, a hole-drilling and medicine-injecting device for agricultural pest control proposed by the present invention includes a fixing plate 1 for clamping crops and a limiting plate 3. The fixing plate 1 is of a fixed design, and the limiting plate 3 is controlled by a distance-adjusting mechanism to adjust the distance from the fixing plate 1. The distance-adjusting mechanism includes a distance-adjusting frame 21 installed on the fixing plate 1. A distance-adjusting screw 22 is installed in the middle of the distance-adjusting frame 21. Distance-adjusting support rods 23 are arranged on both sides of the distance-adjusting screw 22. The distance-adjusting screw 22 is controlled by a distance-adjusting motor 24 to rotate, and a distance-adjusting sliding seat 25 that slides back and forth along the distance-adjusting support rods 23 is sleeved on the outer wall. When it is necessary to adjust the distance between the clamped crops, the fixing plate 1 is attached to the outer wall of the crops. The distance-adjusting motor 24 drives the distance-adjusting screw 22 to rotate. Under the screw drive, the distance-adjusting sliding seat 25 makes a linear displacement along the distance-adjusting support rods 23. The hanging plate 26 installed on the distance-adjusting sliding seat 25 drives the limiting plate 3 to displace synchronously, surrounding the crops between the fixing plate 1 and the limiting plate 3 for preliminary positioning before hole-drilling and medicine-injecting. And the movable design can adapt to the external clamping of different specifications of crops. An inclined support rod is installed at the connection between the hanging plate 26 and the limiting plate 3. The limiting plate 3 can be vertically installed on the side of the hanging plate 26. The support rod is used to increase the connection points and ensure the installation stability. The orientation-adjusting mechanism includes convex plates 41 arranged at intervals on the limiting plate 3. An orientation-adjusting shaft 42 driven by an orientation-adjusting motor 43 to rotate penetrates through the convex plates 41. An orientation-adjusting plate 44 parallel to the opening of the limiting plate 3 is sleeved on the outside of the orientation-adjusting shaft 42. A brush ring part 45 is arranged inside the orientation-adjusting plate 44. According to the needs of agricultural pest control, the corresponding hole-drilling angle needs to be selected. Before hole-drilling, the orientation angle is switched through the orientation-adjusting mechanism. After the fixing plate 1 and the limiting plate 3 are fixed on the outer periphery of the crops, the orientation-adjusting motor 43 drives the orientation-adjusting shaft 42 to rotate, driving the orientation-adjusting plate 44 to rotate between the two convex plates 41. The orientation-adjusting plate 44 rotates 60° clockwise and counterclockwise around the axis of the orientation-adjusting shaft 42. The rotation angle of the orientation-adjusting plate 44 corresponds to the hole-drilling angle of the crops, playing a role in preliminary positioning. When the brush ring part 45 is parallel to the coaxial position of the crops, it is the hole-drilling position. The propulsion mechanism is installed at the lower part of the orientation-adjusting plate 44 and is used to control the hole-drilling mechanism to approach or move away from the crops. The propulsion mechanism includes a propulsion frame 51 that rotates synchronously with the orientation-adjusting plate 44. A main rod 52 is installed in the middle of the propulsion frame 51. Guide rods 53 are arranged on both sides of the main rod 52. The main rod 52 is controlled by a propulsion motor 54 to rotate, and a propulsion sliding seat 55 that slides along the guide rods 53 is sleeved on the outer wall. A support plate platform 56 for lifting is installed above the propulsion sliding seat 55. When the propulsion mechanism works, the propulsion motor 54 drives the main rod 52 to rotate. Under the screw drive, the propulsion sliding seat 55 moves along the guide rods 53 towards the orientation-adjusting plate 44. The moving distance is the hole-drilling depth of the hole-drilling mechanism. The punching mechanism includes a driving device 61. A gearbox 62 is installed at the output end of the driving device 61. A drilling gear 63 that meshes and drives is built inside the gearbox 62. A bearing part 64 on the drilling gear 63 is connected to a hollow drill rod 65, and the combination of the two is a through structure as a whole; A hollow medicine injection rod 7 is clamped inside the drill rod 65. The liquid supply mechanism includes a liquid inlet end seat 81 installed at the other end of the drilling gear 63. A three-way pipe 82 is installed above the liquid inlet end seat 81. The three-way pipe 82 is connected to a medicine liquid tank 83 and a cooling water tank 84 through branch pipes.

[0021] It should be noted that when punching crops, the drill rod 65 is in a high-speed rotation state and advances into the crops along the brush ring part 45.

[0022] In this embodiment, the driving device 61 drives the gearbox 62 to work. A gear set is built inside the gearbox 62. Among them, the drilling gear 63 is the output gear. The gear set meshes and drives to drive the output gear to rotate. The drilling gear 63 is a through structure. The liquid inlet end seat 81 is a fixed design. The combination of the drilling gear 63, the bearing part 64 and the drill rod 65 is on the same axis as a whole. The three rotate along the axis of the liquid inlet end seat 81 under the meshing drive of the gear set, and can drive the drill rod 65 to rotate to punch crops. As the propulsion mechanism works, the punching depth can be controlled; Because a medium transmission channel is left at the axis of the combination of the drilling gear 63, the medicine injection rod 7 and the liquid inlet end seat 81 as a whole, the combined structure of the liquid inlet end seat 81 and the medicine injection rod 7 is used for supplying water and medicine, and the inner cavity of the opening is cleaned and medicine is injected during the punching process, reducing the cumbersome steps of punching and injecting medicine.

[0023] It can be understood that the medicine injection rod 7 is installed through the axis of the drill rod 65. The drill rod 65 has a "twisted" structure, and chip discharge grooves are opened on the outer wall. Through holes are spaced apart on the outer wall of the medicine injection rod 7, and some through holes are exposed at the position of the chip discharge grooves; the chip discharge grooves on the "twisted" structure are used for discharging crop punching debris on the one hand, and on the other hand, during the punching process, the liquid in the cooling water tank 84 can be introduced into the medicine injection holes by the medicine injection rod 7. The cooling liquid can cool the drill rod 65, and during the overflow process of the flowing liquid, the debris remaining in the chip discharge grooves can be cleared out to prevent the subsequent injected medicine liquid from being mixed with the debris and causing waste.

[0024] In order to ensure the synchronous movement of the driving device 61, the medicine liquid tank 83 and the cooling water tank 84, further, the driving device 61, the medicine liquid tank 83 and the cooling water tank 84 are all installed on the pallet table 56, and the three are displaced synchronously with the pallet table 56.

[0025] In an alternative embodiment, the three-way pipe 82 is a three-way structure, and a solenoid valve for controlling the opening and closing of the branch channel is provided at one end connected to the medicine liquid tank 83 and the cooling water tank 84; During the drilling process, the cooling water tank 84 is connected to one branch of the three-way pipe 82, and the opening and closing of the cooling branch is controlled by a solenoid valve. The cooling water sequentially passes through the liquid inlet end seat 81, the drilling gear 63, and the medicine injection rod 7 in the center of the drill pipe 65. Since through holes are provided on the outer periphery of the medicine injection rod 7, the transmitted cooling water cools the drill pipe 65 to prevent the drill pipe 65 from overheating and scalding crops, and the overflowing cooling water can clean debris, facilitating subsequent medicine injection. During the medicine injection process, the medicine liquid tank 83 is connected to the other branch of the three-way pipe 82, and the opening and closing of the medicine injection branch is controlled by a solenoid valve. The medicine liquid is transported to the medicine injection rod 7, and under the action of pressure, the medicine liquid overflows from the through holes for uniform medicine application in the holes.

[0026] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
