[0002] Pest control is an artificial means of reducing or preventing pathogenic microorganisms and pests from harming crops or humans and livestock. It can generally be divided into chemical control using chemical substances such as pesticides and physical control using physical energy such as light or rays or building barriers.

[0003] The prior art discloses an invention patent for a pest control device for agricultural technology promotion (application publication number CN116831097 A), which includes a mobile vehicle, a connecting rod is provided on one side of the mobile vehicle, one end of the connecting rod is fixedly connected to an adjustment column, a bidirectional screw rod is rotatably connected inside the adjustment column, and first sliders are threadedly connected to positions on the outer side of the bidirectional screw rod at opposite thread directions, one end of each first slider is fixedly connected to a connecting column, and one end of each connecting column extends to the outside of the adjustment column and is provided with a first nozzle.

[0004] The above-mentioned existing technology mainly uses a mobile vehicle pushed by manual walking to spray crops with atomizing nozzles.

For example, for corn plants that have grown to a certain height, it is necessary to spray the wall of the stem.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0023] A kind of atomizing spraying equipment for pest control, such as Figure 1 、 Figure 2 、 Figure 3As shown, a mounting assembly 10 is detachably connected to the agricultural vehicle body, and multiple groups of mechanical arm assemblies 20 are installed on the front of the mounting assembly 10. Each mechanical arm assembly 20 is provided with an angle adjustment assembly 30, and a horizontal spraying assembly 40 is provided on the output end of the angle adjustment assembly 30. Each horizontal spraying assembly 40 is provided with a vertical spraying assembly 50. The mounting assembly 10 includes a mounting plate 11 and a height-adjusting plate 12 with adjustable height, and the height-adjusting plate 12 is movably arranged on the mounting plate 11; a through groove adapted to the height-adjusting plate 12 is opened in the front of the mounting plate 11, and a first hydraulic cylinder 13 is fixedly installed at the bottom of the through groove, and the piston end of the first hydraulic cylinder 13 is fixedly connected to the bottom of the height-adjusting plate 12; guide vertical rods 14 are fixedly installed in the cavities on both sides of the through groove, and through grooves are opened in the walls corresponding to the height-adjusting plate 12 and the guide vertical rods 14, and the height-adjusting plate 12 is slidably connected to the two guide vertical rods 14, and multiple groups of assembly grooves 15 are opened on the surrounding walls of the mounting plate 11, and the mounting plate 11 is installed together with the agricultural vehicle body through the assembly grooves 15 and bolts.

[0024] When in use, the present invention can be configured with multiple mounting assemblies 10, at least two, with the number of mounting plates 11 selected based on the specific size of the agricultural vehicle. Bolts are inserted through the mounting slots 15 and then through the vehicle body, and nuts are tightened. The mounting plates 11 are then securely fixed to the side of the agricultural vehicle body, thereby stabilizing the mounting assembly 10, the mechanical arm assembly 20, the angle adjustment assembly 30, the horizontal spray assembly 40, and the vertical spray assembly 50. The height of the height adjustment plate 12 can be adjusted by controlling the operation of the first hydraulic cylinder 13. The height adjustment plate 12 can then be adjusted by driving the mechanical arm assembly 20, the angle adjustment assembly 30, the horizontal spray assembly 40, and the vertical spray assembly 50 to adjust the height, thereby meeting the requirements for atomizing spraying crops at different heights. This provides a highly practical solution.

[0025] like Figure 4 、 Figure 5As shown, the mechanical arm assembly 20 includes an arm column 25, a third hydraulic cylinder 28, a second hydraulic cylinder 24 and a connecting plate 21. The connecting plate 21 is fixedly installed on the lower wall of the front side of the height adjustment plate 12 by bolts. The second hydraulic cylinder 24 is movably arranged between the connecting plate 21 and the arm column 25. One end of the arm column 25 is movable on the wall of the height adjustment plate 12. One end of the third hydraulic cylinder 28 is movably arranged on the arm column 25. The other end of the third hydraulic cylinder 28 is movably arranged on the upper side wall of the front side of the mounting plate 11. A first ear seat 22 is fixedly installed on the top wall of the connecting plate 21 by bolts. One end of the second hydraulic cylinder 24 is fixedly installed on the first ear seat The seat 22 is connected by a pin, and the second ear seat 23 is fixedly installed on the bottom of the arm column 25 by bolts. The piston end of the second hydraulic cylinder 24 is connected to the second ear seat 23 through a pin, and the third ear seat 26 is installed on the middle front wall of the height adjustment plate 12 by bolts. One end of the arm column 25 is connected to the third ear seat 26 through a pin, and the fifth ear seat 29 is installed on the upper side wall of the front of the mounting assembly 10 by bolts. One end of the third hydraulic cylinder 28 is connected to the fifth ear seat 29 through a pin, and the fourth ear seat 27 is installed on the top wall of the arm column 25 by bolts, and the piston end of the third hydraulic cylinder 28 is connected to the fourth ear seat 27 through a pin.

[0026] During use, the overall state of the horizontal spray assembly 40 can be adjusted by controlling the operation of the second hydraulic cylinder 24 and the third hydraulic cylinder 28. When the user drives the agricultural vehicle normally on the ground, the horizontal spray assembly 40 can be rotated and flipped through the mechanical arm assembly 20, which is convenient for driving and walking on the road to avoid collisions and frictions with other vehicles or pedestrians. Through the operation of the second hydraulic cylinder 24, the piston end of the second hydraulic cylinder 24 pushes up the arm column 25, and through the operation of the third hydraulic cylinder 28, the piston rod of the third hydraulic cylinder 28 pulls the arm column 25 upward. Through the dual power operation of the third hydraulic cylinder 28 and the second hydraulic cylinder 24, the stability of the rotation of the arm column 25 and its driving strength can be guaranteed. After the arm column 25 is flipped, the angle adjustment assembly 30 is used to drive the horizontal spray assembly 40 to rotate, so that the horizontal spray assembly 40 is flipped to an upward state, which can realize the flipping and storage of the horizontal spray assembly 40.

[0027] Similarly, when the user drives the agricultural vehicle to the field and needs to perform atomization spraying operations on the crops, the third hydraulic cylinder 28 and the second hydraulic cylinder 24 work together to make the horizontal spraying assembly 40 flip over to the top of the crops for spraying operations.

[0028] like Figure 6 、 Figure 7As shown, the angle adjustment assembly 30 includes a hood 31, a reduction motor 32 and a rotating column 34. The first clamps 60 are installed on the four outer walls of the front end of the arm column 25 by bolts. The other ends of the four first clamps 60 are fixedly connected to the outer wall of the hood 31 by bolts. The hood 31 is hollow, and the reduction motor 32 is fixedly installed in a cavity on one side of the hood 31 close to the first clamp 60. The rotating sleeve 33 is fixedly sleeved in the cavity on the other side of the hood 31. The rotating column 34 is connected to the rotating sleeve 33 through a bearing, and the output end of the reduction motor 32 is connected to the rotating column 34 through a shaft coupling. The other end of the rotating column 34 is fixedly connected to the connecting column 35.

[0029] like Figure 7 、 Figure 8 、 Figure 9 As shown, the horizontal spray assembly 40 includes a horizontal sleeve 41, a first servo motor 43 and multiple reciprocating units arranged in the cavity of the horizontal sleeve 41. The second clamping jaws 36 are installed on the outer wall of the other end of the connecting column 35 by bolts, and the other ends of the four second clamping jaws 36 are fixedly connected to the outer wall of the horizontal sleeve 41 by bolts. The horizontal sleeve 41 is hollow, and the hollow ends on both sides of the horizontal sleeve 41 are installed with covers 42 by bolts. The first servo motor 43 is fixedly installed on the outer wall of the cover 42 near the side of the second clamping jaw 36 through a bracket, and the output end of the first servo motor 43 is fixedly connected to the rotating rod 44 through a shaft coupling. The rotating rod 44 is located in the cavity of the horizontal sleeve 41, and the other end of the rotating rod 44 is rotatably connected to another cover 42, and the reciprocating unit is arranged on the rotating rod 44.

[0030] Specifically, the working angle of the horizontal sleeve 41 can be controlled by the angle adjustment component 30. The user can control the operation of the reduction motor 32. When the reduction motor 32 is working, it can drive the rotating column 34 to rotate. When the rotating column 34 rotates, the horizontal sleeve 41 can be driven to rotate through the connecting column 35 and the second clamp 36. After the horizontal sleeve 41 is rotated, the working angle can be selected, and the vertical spraying component 50 on the horizontal sleeve 41 can be rotated to the bottom. After the vertical spraying component 50 is rotated to the bottom, another spraying operation mode can be performed. This can meet the needs of spraying different crops, or spraying the same crop in different growth cycle states, and is highly practical.

[0031] like Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14As shown, the reciprocating unit includes a guide column 45 fixedly coupled to the rotating rod 44 and a limit frame 49 fixedly connected to the bottom of the horizontal sleeve 41 cavity. The guide column 45 is provided with a guide groove 46 in a spiral shape and connected end to end. The limit frame 49 is provided with a limit groove 61. The limit frame 49 is located directly below the corresponding guide column 45. A reciprocating rod 47 is slidably provided in the limit frame 49. The top of the reciprocating rod 47 is fixedly installed with a first guide rod 48. The top of the first guide rod 48 is arc-shaped, and the arc-shaped top of the first guide rod 48 is located directly below. In the square guide groove 46, sliding grooves 62 are provided on the wall surfaces of the limiting frames 49 on both sides of the limiting groove 61, and sliders 63 adapted to the sliding grooves 62 are fixedly installed on the wall surfaces of both sides of the reciprocating rod 47. The reciprocating rod 47 is limited in the limiting groove 61 by the sliders 63. A plurality of groups of notches 93 are provided on the bottom wall surface of the horizontal sleeve 41, and the reciprocating rod 47 passes through the corresponding notches 93. The bottom end of the reciprocating rod 47 is fixedly connected to the base 64, and the base 64 is located below the horizontal sleeve 41. The bottom of the base 64 is provided with a shaking module and an atomizing nozzle 77. The shaking module includes two ear plates 65 fixedly mounted on the bottom of the base 64, wherein a second servo motor 66 is mounted on the lower outer wall of one of the ear plates 65 through a bracket, and the output end of the second servo motor 66 is fixedly connected to a rotating side rod 67 through a shaft coupling, and a rotating side rod 67 is also rotatably mounted on the lower side wall of the other ear plate 65, and the two rotating side rods 67 are fixedly mounted with inclined plates 68 at one end close to each other, and the two inclined plates 68 are in a parallel state, and a shaft rod 69 is fixedly mounted between the two inclined plates 68, and a shaft sleeve 70 is rotatably mounted on the outer wall of the shaft rod 69, and a sleeve 72 is provided on the outer side of the sleeve 70, and an atomizing nozzle 77 is fixedly provided on the bottom wall of the sleeve 72. A plurality of connecting rods 71 ​​are fixedly installed between the outer wall of the sleeve 70 and the inner wall of the outer sleeve 72. A connecting rod 76 facing vertically downward is fixedly installed at the bottom of the base 64. A guide sleeve 74 is fixedly installed at the bottom of the connecting rod 76. The guide sleeve 74 is arc-shaped. A second guide rod 73 is fixedly installed on the top wall of the outer sleeve 72. A limited swing groove 75 is provided at the bottom of the guide sleeve 74. The top of the second guide rod 73 is in an arc-shaped raised state. The arc-shaped raised end of the second guide rod 73 is movably limited in the limited swing groove 75. A pipeline 78 is fixedly installed between two adjacent atomizing nozzles 77. The bottom of the atomizing nozzle 77 is conical. The pipeline 78 located on the outermost side is connected to the water pump in the medicine box.

[0032] When in use, the agricultural vehicle needs to be equipped with a medicine box, which is loaded with a mixed liquid medicine for pest control. There are two water pumps in the medicine box, and the output end of one of the water pumps is connected to the pipe 78 on the nearest side through a corrugated pipe. The corrugated pipe can be limited by configuring a buckle on the mounting plate 11. When spraying crops, the working switch of the water pump can be turned on, and the water pump will transport the mixed liquid medicine in the medicine box through the corrugated pipe to the pipe 78, and then transport it to each atomizing nozzle 77 through the pipe 78, and finally spray it out through the bottom of the atomizing nozzle 77, so that the atomizing spraying operation of the crops can be realized.

[0033] Furthermore, when atomizing and spraying crops, the working switch of the first servo motor 43 can be turned on. When the first servo motor 43 is working, it drives the rotating rod 44 to rotate. When the rotating rod 44 rotates, it drives all the guide posts 45 to rotate. The rotation of the guide posts 45 drives the guide slots 46 to move. The raised end of the first guide rod 48 is limited in the guide slots 46. In this way, the first guide rod 48 performs a horizontal reciprocating motion. The first guide rod 48 drives the reciprocating rod 47 to perform a horizontal reciprocating motion. The reciprocating rod 47 rotates The slider 63 is limited in the limiting groove 61, which makes the reciprocating rod 47 more stable during the reciprocating motion. The reciprocating rod 47 drives the base 64 to do reciprocating motion, and the base 64 drives the atomizing nozzle 77 below it to do reciprocating motion. When the atomizing nozzle 77 reciprocates, the crops can be quickly sprayed with a reciprocating atomizing agent. This not only improves the spraying efficiency of the crops, but also the atomized liquid during the reciprocating motion can be more evenly dispersed to the crops below, thereby improving the operating efficiency of this technical solution.

[0034] More specifically, when the atomizing nozzle 77 is indirectly driven by the base 64 to perform a reciprocating spraying operation, the working switch of the second servo motor 66 is turned on. When the second servo motor 66 is working, it drives the rotating side rod 67 on one side to rotate, and the rotating side rod 67 on this side drives the inclined plate 68 and the shaft 69 to rotate. At the same time, the second guide rod 73 on the top of the outer sleeve 72 is limited by the guide sleeve 74, and the raised end of the second guide rod 73 is limited in the limiting swing groove 75, so that when the shaft 69 rotates, the outer sleeve 72 is driven and caused to swing. When the outer sleeve 72 swings, it drives the atomizing nozzle 77 at its bottom to swing, and the liquid medicine sprayed by the atomizing nozzle 77 is sprayed in a rotating and swinging manner. The atomized liquid medicine sprayed by the swinging can be further and better sprayed on the crops in all directions, and cooperates with the reciprocating motion above, and finally makes the atomized liquid medicine quickly reciprocate and swing and spray, thereby achieving a dead angle and uniform spraying operation on the crops.

One end of the vertical spray pipe 82 is rotatably mounted on the second fixing plate 81. The output end of the fourth servo motor 59 is fixedly connected to one end of the vertical spray pipe 82. The vertical spray pipe 82 is hollow and has an opening on the outer wall of the vertical spray pipe 82 away from the corresponding second fixing plate 81. There are multiple groups of spray holes. A liquid inlet sleeve 83 is rotatably provided on the outer wall of one end of the vertical spray pipe 82 close to the second fixed plate 81. A third fixed rod 84 is fixedly installed between the liquid inlet sleeve 83 and the second fixed plate 81. A water inlet pipe is fixedly installed on one side wall of the liquid inlet sleeve 83. The water inlet pipe is connected to another water pump in the medicine box through a pipe. Multiple groups of liquid inlet channels 85 are provided on the outer wall of the connection between the vertical spray pipe 82 and the liquid inlet sleeve 83, and multiple groups of liquid outlet channels 86 are provided on the inner wall of the liquid inlet sleeve 83. The liquid inlet sleeve 83 is rotatably connected to the vertical spray pipe 82 through a sleeve bearing and a sealing ring. There are two groups of bearings and sealing rings. Sealed bearings are fixedly provided on the inner walls of both sides of the liquid inlet sleeve 83. The inner walls of the two bearings are fixedly connected to the outer wall of the vertical spray pipe 82. The sealing ring is assembled on the outer side of the two bearings for sealing, so as to ensure the sealing degree of the rotatable connection between the liquid inlet sleeve 83 and the vertical spray pipe 82. A movable collar 88 is movably provided on the outer wall of the vertical spray tube 82, and a plurality of groups of balls 92 are rotatably installed on the annular inner wall of the movable collar 88. The movable collar 88 is movably arranged together with the vertical spray tube 82 through the balls 92. A guide limit groove 94 is provided on the top wall of the top seat 51, and a third servo motor 53 is fixedly installed on the outer wall of one side of the top seat 51 through a bracket. A threaded rod 54 is rotatably installed in the cavity of the guide limit groove 94, and the output end of the top seat 51 is fixedly connected to the threaded rod 54 through a shaft coupling. External threads are provided on the outer walls of both sides of the threaded rod 54, and the external threads on both sides are in opposite directions. Drive blocks 52 are threadedly connected to the outer walls of both sides of the threaded rod 54, and the drive blocks 52 are limited and engaged in the guide limit groove 94. A linkage rod 90 is provided between the drive block 52 and the movable collar 88 on the corresponding side.An avoidance groove is provided on the lower outer wall of one side of the movable collar 88 and the wall surface of one side of the driving block 52, and a pin shaft is rotatably installed in the avoidance groove. The two ends of the linkage rod 90 are fixedly connected to the pin shafts in the two avoidance grooves respectively; a stop block 87 for limiting the movable collar 88 is also fixedly installed on the outer walls of both sides of the vertical spray pipe 82, and the stop block 87 is arc-shaped.

[0036] When in use, the vertical spray assembly 50 on the horizontal sleeve 41 can be rotated to the bottom by controlling the operation of the reduction motor 32, and then the working switch of the third servo motor 53 can be turned on. The third servo motor 53 is a forward and reverse rotation motor. When the third servo motor 53 is working, the third servo motor 53 drives the threaded rod 54 to rotate. When the threaded rod 54 rotates, the two driving blocks 52 slowly move away from each other, and the driving block 52 on each side gradually approaches the vertical spray pipe 82 on the corresponding side. The driving block 52 drives the linkage rod 90 and the movable collar 88 to move synchronously, and the movable collar 88 slides on the vertical spray pipe 82. When the movable collar 88 slides to the stop block 87 on one side, it is blocked. At this time, when the driving block 52 continues to move, the driving block 52 lifts the movable collar 88 through the linkage rod 90, so that the movable collar 88 8 drives the vertical spray pipe 82 to perform a gradual flipping motion, and finally flips the vertical spray pipe 82 to a vertical state. The third servo motor 53 stops working, the driving block 52 does not move, and after the vertical spray pipe 82 flips, the working switch of another water pump in the medicine box is turned on. The water pump transports the liquid medicine through the pipeline to the water inlet pipe of the liquid inlet sleeve 83, and then enters the vertical spray pipe 82 through the liquid inlet sleeve 83, and finally sprays out through the spray holes on the vertical spray pipe 82. The atomized liquid medicine is sprayed onto the crops, realizing atomized spraying of the crops; at the same time, the working switch of the fourth servo motor 59 is turned on. When the fourth servo motor 59 is working, the fourth servo motor 59 drives the vertical spray pipe 82 to rotate. When the vertical spray pipe 82 rotates, the vertical spray pipe 82 can realize rotary atomized spraying, thereby realizing a more comprehensive spraying operation on the crops.

[0037] It is worth noting that when using the vertical spray pipe 82 to spray crops, it is necessary to turn off the operating switch of the other water pump, that is, to stop the atomizing nozzle 77. In addition, the agricultural vehicle, medicine tank, and water pump in this technical solution are all existing technologies and will not be described in detail here. The first hydraulic cylinder 13, the second hydraulic cylinder 24, the third hydraulic cylinder 28, the reduction motor 32, the first servo motor 43, the second servo motor 66, the third servo motor 53, the fourth servo motor 59, and the water pump are all powered by the agricultural vehicle.

[0038] When the vertical spray pipe 82 is rotated to spray the crops downward, it can meet the needs of some crops with higher growth heights, such as corn and other crops. After the vertical spray pipe 82 is flipped to a vertical downward state, the vertical spray pipe 82 is located in the corn plant. When the agricultural vehicle is moving, the vertical spray pipe 82 rotates and sprays during the movement, and the liquid medicine can be rotated and sprayed onto the stem of the plant. Compared with spraying medicine from above the plant, this method can perform atomization spraying in a more comprehensive manner. For crops in different states or for crops in different growth cycles, this technical solution can be selected according to actual operations to meet the atomization spraying operations of different crops.
