Description

Technical Field

[0001] The invention relates to the technical field of pesticide application equipment, and in particular to a side spray device for targeted and precise pesticide application by an unmanned aerial vehicle. Background Art

[0002] The pesticide application drone is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flight platform, a navigation flight control, and a spraying mechanism. The spraying operation is achieved through ground remote control or navigation flight control. The unmanned small helicopter has the advantages of low operating altitude, less drift, and can hover in the air, without the need for a dedicated take-off and landing airport.

[0003] Chinese patent CN214356707U discloses a liquid spray head for pesticide application drones, which relates to the technical field of liquid spray heads, and specifically includes a medicine storage box, the upper surface of which is plugged with a material guide port, one end of which is threadedly connected to a sealing cover, one side of the medicine storage box is fixedly connected to a mounting plate, the inner thread of the mounting plate is connected to a fixing nail, one side of the fixing nail is threadedly connected to a fixing ring, the number of the fixing nails and the fixing ring are both four, and the fixing nails are respectively arranged at the four corners of the mounting plate. The liquid spray head for pesticide application drones, through the arrangement of the mounting plate, enables the liquid spray head for pesticide application drones to have the effect of convenient installation and stable fixation, and through the coordinated arrangement of the sliding block, the connecting block, the fixing column and the shunt pipe, the distance between the atomizing nozzles can be conveniently adjusted during use, which can meet the needs of different spraying concentrations and achieve the effect of uniform spraying, thereby playing a role in a wide range of use and achieving the purpose of easy adjustment and uniform spraying.

[0004] However, the drone sprays pesticides on crops through a large-scale spraying method. Although the application range is wide and the speed is fast, because it applies pesticides from top to bottom, part of the pesticides fall directly on the ground, making it impossible to accurately apply pesticides to the diseased locations of crops, resulting in a large amount of pesticide waste.

[0005] Therefore, it is necessary to provide a UAV targeted precision pesticide side spraying device to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a side spray device for targeted and precise pesticide application by an unmanned aerial vehicle to solve the problems raised in the above-mentioned background technology.

[0007] Based on the above ideas, the present invention provides the following technical solutions: a side spray device for targeted precision drug application of unmanned aerial vehicles, comprising a mounting plate and a support box, wherein the support box is connected to the mounting plate through a shock absorbing mechanism, a side wall of the support box is connected to a support tube, an end of the support tube away from the support box is fixedly connected to an adjusting tube, an end of the adjusting tube away from the support tube is fixedly installed with a spray nozzle, a drug inlet is provided at the top of the support box, the drug inlet is connected to the spray nozzle through a drug delivery tube, an adjusting mechanism is provided in the adjusting tube, and the adjusting mechanism is used to drive the adjusting tube to bend.

[0008] During specific use, the device is installed on the side wall of the drone through the mounting plate, and the medicine box of the drone is connected to the medicine inlet. When applying medicine, the medicine liquid is input into the medicine inlet, and the medicine liquid is input into the medicine spray nozzle through the medicine delivery tube and sprayed out through the medicine spray nozzle. The distance between the medicine spray nozzle and the drone can be extended through the support tube, so that the distance between the medicine spray nozzle and the crops is closer to reduce the deviation of the spraying. The adjustment mechanism can drive the adjustment tube to bend, thereby adjusting the height and spraying direction of the medicine spray nozzle, so that the medicine liquid is sprayed toward the target position. The shock-absorbing mechanism can reduce the impact of the drone's own vibration on the medicine spray nozzle, so that the medicine spray nozzle is more stable when spraying the medicine liquid, and can carry out targeted and precise application of medicine at a certain position of the crops, thereby reducing the use of pesticides, reducing planting costs, and improving the quality of crops.

[0009] As a further solution of the present invention, the adjustment mechanism includes an adjustment ring and an adjustment rope. There are multiple adjustment rings, and the multiple adjustment rings are all arranged in the adjustment tube. The multiple adjustment rings are coaxially arranged, and the tops of the opposite side walls of two adjacent adjustment rings are elastically connected by an elastic connecting plate. A rope threading hole is provided at the bottom of the adjustment ring, and the adjustment rope passes through all the rope threading holes in sequence. A traction mechanism for driving the adjustment rope to move is provided in the support box, one end of the adjustment rope is fixedly connected to the adjustment ring closest to the spray nozzle, and the other end of the adjustment rope is transmission-connected to the traction mechanism.

[0010] During specific use, when driving the adjusting tube to bend, the adjusting rope is driven to move toward the supporting box through the traction mechanism. When the adjusting rope moves, the bottom of the adjusting ring at the rightmost end is pulled toward the supporting box, thereby driving the elastic connecting plate to bend downward. The adjusting ring at the rightmost end transmits the pulling force to the adjacent adjusting ring through the elastic connecting plate, thereby driving the adjacent elastic connecting plate to bend, so that the entire adjusting tube is bent. The greater the distance the adjusting rope moves to the left, the greater the degree of downward bending of the adjusting tube, thereby realizing the bending of the adjusting tube driven by the adjusting mechanism. When the adjusting rope moves to the right, the adjusting ring returns to its initial state under the elastic action of the elastic connecting plate itself.

[0011] As a further solution of the present invention, the traction mechanism includes a rotating shaft and a motor, the rotating shaft is rotatably installed in the support box, the motor is fixedly installed on the top of the support box, the output end of the motor is transmission connected to the rotating shaft, the rotating shaft is provided with a rope winding wheel, and the end of the adjustment rope away from the spray nozzle is fixedly connected to the rope winding wheel.

[0012] As a further solution of the present invention, a first bevel gear is fixedly mounted on the output end of the motor, a second bevel gear is sleeved on the rotating shaft, and the first bevel gear is meshed with the second bevel gear.

[0013] During specific use, when the motor is turned on, it drives the first bevel gear to rotate, and when the first bevel gear rotates, it drives the second bevel gear to rotate, and when the second bevel gear rotates, it drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the rope winding wheel to rotate. When the rope winding wheel rotates, the adjusting rope is gradually wound around the rope winding wheel, thereby driving the left end of the adjusting rope to move into the support box. When the output end of the motor reverses, the adjusting rope is gradually released from the rope winding wheel, thereby resetting the adjusting ring.

[0014] As a further solution of the present invention, two shock absorbing mechanisms are provided, and the two shock absorbing mechanisms are respectively provided at both ends of the support box, the shock absorbing mechanism includes a mounting box, the mounting box is fixedly connected to the mounting plate through a connecting rod, both ends of the support box are connected with elastic connecting elements, one end of the elastic connecting element extends into the mounting box, a disc is fixedly installed on the end of the elastic connecting element extending into the mounting box, and a buffer airbag is fixedly installed on the outer peripheral wall of the disc.

[0015] During specific use, through the cushioning effect of the cushioning airbag, when the drone drives the installation box to vibrate, the vibration of the installation box along the length direction and longitudinal direction of the connecting rod is difficult to be directly transmitted to the elastic connecting element, thereby playing a cushioning role.

[0016] As a further solution of the present invention, the elastic connecting element includes a connecting tube and a connecting column, one end of the connecting tube is fixedly connected to the end of the installation box, one end of the connecting column extends into the connecting tube, and the connecting column and the connecting tube are slidably matched, a spring is arranged in the connecting tube, one end of the spring is fixedly connected to the inner side wall of the connecting tube, the other end of the spring is fixedly connected to the connecting column, and the end of the connecting column away from the connecting tube is fixedly connected to the disc.

[0017] During specific use, under the elastic action of the spring, the vibration of the support box in the length direction of the support box can be buffered, so that the vibrations in three directions can be buffered, thereby reducing the impact of the drone's own vibration during flight on the stability of the spray nozzle, thereby making the spraying more accurate and reducing the waste of liquid medicine.

[0018] As a further solution of the present invention, a through hole is opened on the side wall of the installation box, the connecting column passes through the through hole, the diameter of the connecting column is smaller than the diameter of the through hole, and the diameter of the disk is larger than the diameter of the through hole.

[0019] As a further solution of the present invention, a plurality of the buffer airbags are provided, and the plurality of the buffer airbags are distributed in a circular array with the axis of the disk as the array center, a gap is provided between two adjacent buffer airbags, and a fixing component for fixing the buffer airbag is provided in the installation box.

[0020] As a further solution of the present invention, the fixing assembly includes a fixing plate, which is arranged in an arc shape, and a limiting plate is fixedly installed on the fixing plate close to the side wall of the disc, and the limiting plate is inserted into the gap between two adjacent buffer airbags, and an adjusting bolt is rotatably installed on the limiting plate away from the side wall of the disc, and the adjusting bolt passes through the side wall of the mounting box, and the adjusting bolt is threadedly connected to the mounting box, and an adjusting knob is fixedly installed on the end of the adjusting bolt away from the disc.

[0021] During specific use, it is difficult to fix the mounting plate on the side walls of some drones, so the mounting plate needs to be fixed on the bottom wall of the drone. At this time, the direction of the support tube needs to be adjusted. When adjusting, first rotate the adjusting bolt through the adjusting knob to make the adjusting bolt drive the fixing plate to move in the direction away from the disc. When the fixing plate moves, it drives the limit plate to move, so that the limit plate is moved out of the gap between the buffer airbags, so that the disc can rotate. Then rotate the support tube 90°, so that the disc is driven to rotate 90° through the support box and the elastic connecting element, so that the support tube is in a horizontal state, and then tighten the adjusting bolt through the adjusting knob to move the fixing plate toward the disc, so that the limit plate is reinserted into the gap between the buffer airbags, thereby limiting the buffer airbag and the disc, making it difficult to rotate significantly. The buffer airbag can be better fixed by the limit plate, and the above structure enables the position of the support tube to be adjusted, so that there are multiple options for the installation position of the mounting plate, which is convenient for the installation of the device.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention can extend the distance between the spray nozzle and the UAV through the support tube, so that the distance between the spray nozzle and the crops is closer to reduce the deviation of the spraying; the adjustment mechanism can drive the adjustment tube to bend, thereby adjusting the height and spraying direction of the spray nozzle, so that the liquid medicine is sprayed toward the target position; the shock-absorbing mechanism can reduce the influence of the UAV's own vibration on the spray nozzle, so that the spray nozzle is more stable when spraying liquid medicine, and can carry out targeted and precise application of pesticides at a diseased position of the crops, thereby reducing the amount of pesticides used, reducing the planting cost, reducing the drug residues on the crops, and improving the quality of the crops.

[0044] Working principle: When applying pesticides, liquid medicine is input into the medicine inlet 6, and the liquid medicine is input into the medicine spraying nozzle 5 through the medicine delivery tube 7 and sprayed out through the medicine spraying nozzle 5. The distance between the medicine spraying nozzle 5 and the UAV can be extended through the support tube 3, so that the distance between the medicine spraying nozzle 5 and the crops is closer to reduce the deviation of the spraying. The adjusting mechanism can drive the adjusting tube 4 to bend, thereby adjusting the height and spraying direction of the medicine spraying nozzle 5, so that the liquid medicine is sprayed toward the target position. The shock absorbing mechanism can reduce the influence of the vibration of the UAV itself on the medicine spraying nozzle 5, so that the medicine spraying nozzle 5 is more stable when spraying liquid medicine; when driving the adjusting tube 4 to bend, the motor 13 is turned on, and when the motor 13 is turned on, it drives the first bevel gear 14 to rotate, and when the first bevel gear 14 rotates, it drives the second bevel gear 14 to rotate. The gear 15 rotates, and when the second bevel gear 15 rotates, it drives the rotating shaft 11 to rotate. When the rotating shaft 11 rotates, it drives the rope wheel 12 to rotate. When the rope wheel 12 rotates, the adjusting rope 10 is gradually wound around the rope wheel 12, thereby driving the left end of the adjusting rope 10 to move into the supporting box 2. When the adjusting rope 10 moves, it pulls the bottom of the rightmost adjusting ring 8 to move toward the supporting box 2, thereby driving the elastic connecting plate 9 to bend downward. The rightmost adjusting ring 8 transmits tension to the adjacent adjusting ring 8 through the elastic connecting plate 9, thereby driving the adjacent elastic connecting plate 9 to bend, thereby making the entire adjusting tube 4 bend. The greater the distance the adjusting rope 10 moves to the left, the greater the degree of downward bending of the adjusting tube 4, thereby achieving the adjustment driven by the adjusting mechanism. The joint tube 4 is bent, and when the adjustment rope 10 moves to the right, the adjustment ring 8 returns to its initial state under the elastic action of the elastic connecting plate 9 itself; through the buffering effect of the buffer airbag 19, when the drone drives the installation box 16 to vibrate, the vibration of the installation box 16 along the length direction and longitudinal direction of the connecting rod 17 is difficult to be directly transmitted to the elastic connecting element, thereby playing a buffering role. Under the elastic action of the spring, the vibration of the support box 2 in the length direction of the support box 2 can be buffered, so that the vibrations in three directions can be buffered, thereby reducing the influence of the drone's own vibration during flight on the stability of the spray nozzle 5, thereby making the spraying more accurate and reducing the waste of liquid medicine; when it is necessary to adjust the direction of the support tube 3, first pass The adjusting bolt 23 is rotated by the adjusting knob 24 so that the adjusting bolt 23 drives the fixing plate 22 to move in the direction away from the disc 18. When the fixing plate 22 moves, it drives the limiting plate 25 to move, so that the limiting plate 25 is moved out from the gap between the buffer airbags 19, so that the disc 18 can rotate. Then the support tube 3 is rotated 90°, so that the disc 18 is driven to rotate 90° through the support box 2 and the elastic connecting element, so that the support tube 3 is in a horizontal state. Then the adjusting bolt 23 is tightened by the adjusting knob 24 to move the fixing plate 22 toward the disc 18, so that the limiting plate 25 is reinserted into the gap between the buffer airbags 19, thereby limiting the buffer airbags 19 and the disc 18, making it difficult to rotate significantly.

[0045] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
