Description

Technical Field

[0001] The present invention relates to the technical field of pest control, and in particular to a precise pesticide application device for pest control. Background Art

[0002] Pest and disease control is an important task in many fields such as agricultural production, forestry management, urban greening and public health. It aims to reduce or eliminate the harm of pests and diseases to plants, human health and the ecological environment through scientific and reasonable methods, and to ensure crop yield and quality, forest health, urban greening landscape effects and public health safety.

[0003] After searching, the Chinese patent with the announcement number CN118614484B discloses a precision spraying device for agricultural pest control, including a box and a motor, the lower surface of the box is fixedly provided with a walking assembly, and the upper surface of the box is fixedly connected to a handle, and the upper surface of the box is provided with a feed port; it also includes: an auxiliary plate, the auxiliary plate is fixedly connected to the inner wall of the external frame, and the internal sliding of the auxiliary plate is provided with a knocking rod, and the surface of the knocking rod is fixedly connected to the external plate. During use, when it is necessary to adjust the height of the automatic sprinkler, the motor can be started to drive the column to rotate, and then the movable plate, fixed block, automatic sprinkler and connecting pipe move in the vertical direction under the action of the limit column and the column. At this time, the automatic sprinkler can be moved to the appropriate position, so that the automatic sprinkler is accurately aligned with the diseased position of the crop, which improves the accuracy and makes the medicine work better. However, when this solution is actually used, there are still the following shortcomings: Although the above-mentioned pesticide application device can adjust the height of the automatic nozzle through a movable plate to adapt to the approximate spraying requirements of crops at different growth stages, its automatic nozzle is always fixed in a position during operation so that it can only spray the area outside the box, and the spraying range and method are relatively simple. For crops such as tea trees that have special growth forms and spraying requirements, the ideal spraying effect should be a covering type, that is, the sprayed liquid can evenly cover all parts of the tea tree, thereby ensuring the comprehensiveness and effectiveness of pest control. However, due to the limitations of the nozzle spraying method, the existing pesticide application device cannot achieve this covering spraying effect, which seriously restricts its widespread application in specific crop planting fields.

[0023] Reference Figure 1 、 Figure 9 As shown, a driving assembly 7 corresponding to the conversion assembly 5 is provided at the top of the lifting assembly 4. The driving assembly 7 includes two fixed shells 71 fixedly mounted on the top surface of the fixed box 41. A winding disk 72 is rotatably mounted on the inner wall of the fixed shell 71. A pull rope 74 is provided on the inner side of the winding disk 72, and one end of the pull rope 74 passes through the fixed shell 71 and is fixedly connected to the side surface of the pulling plate 52.

The staff can form the pulling plate 52, the section plate 53 and the adjusting plate 54 into a straight line. When the straight line is in a vertical state, it can accurately apply pesticides to taller plants such as corn. When the straight line is in a horizontal state, it can accurately apply pesticides to ordinary low-lying plants. The straight line structure can be driven by the pull rope 74 when switching between the horizontal and vertical states. Specifically, Figure 1 In the state shown, the pulling plate 52 is in a vertical state, and the pull rope 74 is in a taut state. By controlling the drive motor 73, the winding disk 72 can be driven to unwind the pull rope 74. At this time, through the unwinding of the pull rope 74, the straight-line structure composed of the pulling plate 52, the section plate 53 and the adjustment plate 54 can be transformed into a horizontal state.

[0024] Reference Figure 4 、 Figure 7 、 Figure 8As shown, the conversion assembly 5 is provided with several groups of protective assemblies 8, which include a bracket 81 fixedly mounted on the side of the pulling plate 52, and a second elastic telescopic rod 82 is rotatably mounted on the end of the bracket 81. The telescopic end of the second elastic telescopic rod 82 is fixedly mounted with a protective plate 83. The protective assembly 8 also includes a torsion spring 84 sleeved on the outer wall of the second elastic telescopic rod 82, and the two ends of the torsion spring 84 are respectively fixedly connected to the bracket 81 and the second elastic telescopic rod 82. A set gear 85 is fixedly sleeved on the outer wall of the fixed end of the second elastic telescopic rod 82. The protective plate 83 is frustum-shaped, and a linkage structure 9 is provided between the set gear 85 and the connecting pipe 57. The linkage structure 9 includes a connecting tube 91 that passes through the outer wall of the connecting tube 57. A piston plate 92 is slidably mounted on the inner wall of the connecting tube 91. A linkage frame 93 is fixedly mounted on the top surface of the piston plate 92. The linkage frame 93 extends from one end of the piston plate 92 to the position of the set gear 85. A spring 94 is mounted on the outer wall of the linkage frame 93. The two ends of the spring 94 are respectively fixedly connected to the piston plate 92 and the connecting tube 91. A drive rack 95 that meshes with the set gear 85 is fixedly mounted on the end of the linkage frame 93. When the entire device is not in use, the protective plate 83 can be positioned at Figure 4 The position of the atomizing nozzle 56 is covered to prevent the atomizing nozzle 56 from being blocked by dust accumulation or interference from impurities when the atomizing nozzle 56 is not in use. When in use, after the shape adjustment of the pulling plate 52, the section plate 53 and the adjusting plate 54 is completed, the driving base 1 can be moved. At this time, the water pump 3 is turned on and the liquid in the medicine storage barrel 2 can be pumped into the conduits 55 on both sides through the liquid inlet pipe 10 and the liquid outlet pipe 11, and enters the atomizing nozzle 56 through the connecting pipe 57 for spraying. When the liquid enters the connecting pipe 57 under the action of pressure, it can simultaneously enter the connecting pipe 91 and push the piston plate 92 to make the piston plate 92 and the linkage frame 93 move upward. When the linkage frame 93 moves upward, it can drive the set gear 85, the elastic telescopic rod 2 82, and the protective plate 83 to rotate by driving the rack 95. After the protective plate 83 rotates, the atomizing nozzle 5 6. It ensures that the medicine liquid can be sprayed through the atomizing nozzle 56. When the protective plate 83 rotates and separates from the atomizing nozzle 56, under the elastic force of the elastic telescopic rod 2 82, the protective plate 83 can move in the direction of shortening the elastic telescopic rod 2 82, so as to make way for the atomizing nozzle 56 and avoid affecting the spraying range of the atomizing nozzle 56. When the atomizing nozzle 56 is not in use, the water pump 3 stops and the pressure in the conduit 55 is lost. Under the action of the spring 2 94, the piston plate 92 can be reset and the driving rack 95 can slide in the opposite direction, thereby driving the elastic telescopic rod 2 82 to reverse. At this time, under the action of the outer wall inclined surface of the protective plate 83, when the protective plate 83 contacts the atomizing nozzle 56, the elastic telescopic rod 2 82 can extend and continue to rotate, and finally can be located on the side of the atomizing nozzle 56 to cover and protect it, thereby preventing the atomizing nozzle 56 from being contaminated.

[0025] Working principle: When in use, the staff can first add the medicine to be applied into the medicine storage barrel 2, and the driving base 1 can be operated by the staff. During the application process, the water pump 3 and the driving base 1 can be started synchronously to accurately apply the medicine to the application area. Before applying the medicine, the staff can first adjust the height of the application structure according to the situation of the application area. During adjustment, the servo motor 45 can be controlled to drive the adjusting screw 43 to rotate. The guide plate 44 is slidably connected to the inner wall of the fixed box 41 and is screwed to the adjusting screw 43. Therefore, when the adjusting screw 43 rotates, it can drive the guide plate 44 to slide along the inner wall of the fixed box 41, thereby realizing the adjustment of the height of the application structure to adapt to different application areas for use; Then the staff can adjust the shape of the pulling plate 52, the section plate 53 and the adjusting plate 54 according to the different types of plants to be applied. First, the pulling plate 52, the section plate 53 and the adjusting plate 54 can be formed. Figure 1 In the form shown, the pulling plate 52, the section plate 53 and the adjusting plate 54 form a U-shape. The plants to be sprayed can be located on the inner side of the U-shaped structure for precise coating and spraying. The size of the U-shape can be adjusted. When adjusting, the staff can rotate the thread head 66 so that the thread head 66 moves out of the thread groove 67, and the adjusting plate 54 can be rotated to a position horizontal to the section plate 53. Then, under the action of the spring 1 64, the connecting plate 63 and the slide plate 62 can slide into the slot 61, and the limit frame 68 can be engaged into the limit groove 69 to form a stable connection. According to the size of the plant, the staff can bend the corresponding positions between the segment plates 53 to form a new U-shape. During the specific operation, the staff can pull the selected segment plate 53 to drive the slide plate 62 to slide along the slot 61 through the connecting plate 63. When the connecting plate 63 slides out of the slot 61, the pulled segment plate 53 can be rotated to a vertical state, and then the thread head 66 can be screwed into the thread groove 67. Under the limiting action of the elastic telescopic rod 65, the thread head 66 and the thread groove 67, the whole can form a new stable U-shaped structure for use, so as to carry out precise pesticide application according to the needs of plants of different sizes. According to the above bending steps, the staff can also form the pulling plate 52, the section plate 53, and the adjusting plate 54 into a straight line. When the straight line is in a vertical state, it can accurately apply pesticides to taller plants such as corn. When the straight line is in a horizontal state, it can accurately apply pesticides to ordinary low-lying plants. The straight line structure can be driven by the pull rope 74 when switching between the horizontal and vertical states. Specifically, Figure 1 In the state shown, the pulling plate 52 is in a vertical state, and the pull rope 74 is in a taut state. The drive motor 73 is controlled to drive the reel 72 to unwind the pull rope 74. At this time, through the unwinding of the pull rope 74, the straight-line structure composed of the pulling plate 52, the section plate 53 and the adjustment plate 54 can be transformed into a horizontal state. When the entire device is not in use, the protective plate 83 can be positioned at Figure 4 The position of the atomizing nozzle 56 is covered to prevent the atomizing nozzle 56 from being blocked by dust accumulation or interference from impurities when the atomizing nozzle 56 is not in use. When in use, after the shape adjustment of the pulling plate 52, the section plate 53 and the adjusting plate 54 is completed, the driving base 1 can be moved. At this time, the water pump 3 is turned on and the liquid in the medicine storage barrel 2 can be pumped into the conduits 55 on both sides through the liquid inlet pipe 10 and the liquid outlet pipe 11, and enters the atomizing nozzle 56 through the connecting pipe 57 for spraying. When the liquid enters the connecting pipe 57 under the action of pressure, it can simultaneously enter the connecting pipe 91 and push the piston plate 92 to make the piston plate 92 and the linkage frame 93 move upward. When the linkage frame 93 moves upward, it can drive the set gear 85, the elastic telescopic rod 2 82, and the protective plate 83 to rotate by driving the rack 95. After the protective plate 83 rotates, the atomizing nozzle 5 6. It ensures that the medicine liquid can be sprayed through the atomizing nozzle 56. When the protective plate 83 rotates and separates from the atomizing nozzle 56, under the elastic force of the elastic telescopic rod 2 82, the protective plate 83 can move in the direction of shortening the elastic telescopic rod 2 82, so as to make way for the atomizing nozzle 56 and avoid affecting the spraying range of the atomizing nozzle 56. When the atomizing nozzle 56 is not in use, the water pump 3 stops and the pressure in the conduit 55 is lost. Under the action of the spring 2 94, the piston plate 92 can be reset and the driving rack 95 can slide in the opposite direction, thereby driving the elastic telescopic rod 2 82 to reverse. At this time, under the action of the outer wall inclined surface of the protective plate 83, when the protective plate 83 contacts the atomizing nozzle 56, the elastic telescopic rod 2 82 can extend and continue to rotate, and finally can be located on the side of the atomizing nozzle 56 to cover and protect it, thereby preventing the atomizing nozzle 56 from being contaminated.
