Description

Technical Field

[0001] The invention relates to the technical field of crop growth, and in particular to a crop growth monitoring drone. Background Art

[0002] Agricultural drones include two types, helicopters and multi-rotor drones, which can be controlled by ground remote control or navigation flight control. With the development of science and technology, especially the development of battery technology, the drone market has expanded rapidly, and more and more people are starting to use drones for pesticide spraying operations.

[0003] Before using drones to spray pesticides on crops in farmland, it is often necessary to have a detailed understanding of the scope of the farmland to be sprayed and related conditions such as pests and diseases. Using manpower to patrol is time-consuming and labor-intensive. After spraying pesticides, it is often necessary to sample and test the water quality of the farmland, which is inconvenient for manual sampling.

[0004] In order to overcome the above-mentioned defects, a crop planting monitoring drone with publication number CN219277789U includes a drone body, a water collecting tank is fixedly connected to the bottom of the drone body, a circular driving plate is connected to the inside of the water collecting tank through a driving mechanism, the driving plate is connected to a lifting plate through a lifting mechanism, and the bottom of the lifting plate is connected to a pumping pipe through a pumping mechanism. When the present invention is in use, the driving motor will drive the driving plate to rotate through the driving rod, and the driving plate will drive the ring to make a circular motion around the driving rod through the connecting rod during the rotation process. The ring will drive the lifting handle to move up and down intermittently through the lifting rod, the rotating rod and the fixed plate, and the lifting plate that moves up and down will also drive the piston to move up and down intermittently through the pumping rod. At this time, water can be sucked from the water inlet pipe into the pumping pipe, and then the water can be discharged to the inside of the water collecting tank through the first one-way valve, so that the sampling of farmland water quality can be completed quickly.

[0005] Although the existing design can solve the above problems, it is too complicated for the design that needs to be used for pesticide spraying, which brings a lot of inconvenience to some farmers who are not proficient in the use of intelligent machinery. In addition, the observation angle of most drones is limited, and they cannot move up and down well to obtain a larger angle of observation. Summary of the invention

[0006] The purpose of the present invention is to provide a crop growth monitoring drone to solve the problems raised in the above-mentioned background technology that the design for pesticide spraying is too complicated, which brings a lot of inconvenience to some farmers who are not proficient in the use of intelligent machinery, and most drones have limited observation angles and cannot move up and down well to obtain a larger angle of observation.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a crop growth monitoring drone, comprising a flight component installed above the drone top plate, and a connecting support plate installed on the lower surface of the drone top plate, sliding angle plates installed on the left and right sides of the connecting support plate, and an elastic transmission mechanism for internally penetrating a hydraulic spray pipe is installed inside the sliding angle plate, the elastic transmission mechanism comprises an intelligent reversing motor, and the intelligent reversing motor is installed on the upper surface of the connecting support plate, a fixed rotating disk is installed at the output end of the lower surface of the intelligent reversing motor, and a resisting semicircular rod is installed on the lower surface of the fixed rotating disk, a medicine storage tank is installed above the connecting support plate, and a hydraulic spray pipe is installed on the side of the medicine storage tank; an intelligent reversing motor is installed above the connecting support plate, and an engaging sliding mechanism for transmitting a detection camera is installed at the upper output end of the intelligent reversing motor.

[0008] Furthermore, the meshing sliding mechanism includes a fixed gear, and the fixed gear is fixedly installed on the upper output end of the intelligent reversing motor. Two groups of sliding angle plates are installed symmetrically about the center point of the connecting support plate, and a driven worm is installed in the middle of the two groups of sliding angle plates.

[0009] Furthermore, the driven worm and the fixed gear are in contact with each other, and a passive rotating gear is installed on the outer surface of the driven worm, an engaging gear rod is installed on the outer surface of the passive rotating gear, and a sliding transmission rod is installed on the back of the engaging gear rod, a sliding limit frame is installed on the back of the sliding transmission rod, and a resisting sliding frame is installed inside the sliding limit frame, the resisting sliding frame is fixedly installed on the upper surface of the connecting support plate, and a detection camera is installed at the end of the sliding transmission rod.

[0010] Furthermore, the medicine storage tank is connected to the inside of the hydraulic spray pipe, and a sliding inner groove is opened at the bottom of the inner surface of the medicine storage tank, a rotating blocking plate is installed inside the sliding inner groove, and the rotating blocking plate is rotatably installed inside the sliding inner groove, and a concave interference frame is installed on the outer surface of the lower end of the rotating blocking plate, and the concave interference frame is a semicircular concave design.

[0011] Furthermore, the rotation track of the interfering semicircular rod contacts the concave interfering frame, and a sliding rod is installed on the outer surface of the hydraulic spraying pipe. The hydraulic spraying pipe is rotatably installed at the end of the sliding rod, and the upper end of the sliding rod is slidably installed inside the sliding angle plate.

[0012] Furthermore, the concave interference frame and the rotating blocking plate are of an integrated design, and the end of the interference semicircular rod is of a semicircular design, and two groups of the interference semicircular rods are installed symmetrically about the center point of the fixed rotating disk.

[0013] Furthermore, the inner surface of the sliding limit frame contacts the outer surface of the abutting sliding frame to form a sliding structure, and the meshing gear rod and the sliding transmission rod are of an integrated design.

[0014] Compared with the prior art, the beneficial effect of the present invention is that when the crop growth monitoring drone needs to spray medicine, the intelligent reversing motor is first started to work, and the intelligent reversing motor drives the interference semicircular rod to rotate in a circle through the fixed rotating disk, and pushes the concave interference frame while the interference semicircular rod rotates, and the concave interference frame simultaneously interferes with the lower end of the rotating blocking plate, and the rotating blocking plate swings along the sliding inner groove. Since the upper end of the rotating blocking plate blocks the connection between the medicine storage box and the hydraulic spray pipe, the rotation of the rotating blocking plate connects the hydraulic spray pipe to complete the spraying of the medicine.

[0015] Furthermore, when it is necessary to move the detection camera, the intelligent reversing motor is used to drive the fixed gear to produce meshing motion with the driven worm. The driven worm rotates in a circle under the drive of the meshing motion, and the fixed passive rotating gear also rotates at the same time. The rotation of the passive rotating gear transmits the meshing gear rods that are in contact with each other. Since the sliding transmission rod is fixed at the end of the meshing gear rod, and the detection camera is fixed at the lower end of the sliding transmission rod, the intelligent reversing motor can be controlled to control the length of the detection camera.

[0016] Furthermore, the hydraulic spray pipe is rotatably installed inside the sliding movable rod, and the upper end of the sliding movable rod is slidably installed inside the sliding angle plate. The spraying range of the pesticide can be adjusted by sliding the sliding movable rod along the inside of the sliding angle plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-Figure 6 The present invention provides the following technical solution: a crop growth monitoring drone, comprising a drone top plate 1, a flight assembly 2 and a sliding moving rod 22. The flight assembly 2 is installed on the top of the drone top plate 1, and a connecting support plate 3 is installed on the lower surface of the drone top plate 1, and sliding angle plates 6 are installed on the left and right sides of the connecting support plate 3, and an elastic transmission mechanism for internally penetrating the hydraulic spray pipe 5 is installed inside the sliding angle plate 6, and the elastic transmission mechanism includes an intelligent reversing motor 21, and the intelligent reversing motor 21 is installed on the upper surface of the connecting support plate 3, and a fixed rotating disk 8 is installed at the output end of the lower surface of the intelligent reversing motor 21, and a resisting semicircular rod 9 is installed on the lower surface of the fixed rotating disk 8, and a liquid medicine storage box 4 is installed on the top of the connecting support plate 3, and a hydraulic spray pipe 5 is installed on the side of the liquid medicine storage box 4; the intelligent reversing motor 21 is installed on the top of the connecting support plate 3, and a meshing sliding mechanism for transmitting the detection camera 7 is installed at the upper output end of the intelligent reversing motor 21.

[0026] like Figure 2 , Figure 3 , Figure 5The technical solution shown, in order to solve the problem that the current equipment's medicine spraying design is too complicated, discloses: a medicine storage tank 4 is connected to the inside of a hydraulic spray pipe 5, and a sliding inner groove 12 is provided at the bottom of the inner surface of the medicine storage tank 4, a rotating blocking plate 11 is installed inside the sliding inner groove 12, and the rotating blocking plate 11 is rotatably installed inside the sliding inner groove 12, a concave interference frame 10 is installed on the outer surface of the lower end of the rotating blocking plate 11, and the concave interference frame 10 is a semicircular concave design, and the rotation trajectory of the interference semicircular rod 9 contacts the concave interference frame 10, and a sliding moving rod 22 is installed on the outer surface of the hydraulic spray pipe 5, the hydraulic spray pipe 5 is rotatably installed at the end of the sliding moving rod 22, and the upper end of the sliding moving rod 22 is slidably installed inside the sliding angle plate 6, the concave interference frame 10 and the rotating blocking plate 11 are of an integrated design, and the end of the interference semicircular rod 9 is a semicircular design, and two groups of interference semicircular rods 9 are installed symmetrically about the center point of the fixed rotating disk 8.

[0027] When it is necessary to spray the crops with medicine, first start the flight component 2 fixedly installed on the top plate 1 of the UAV, so that the flight component 2 drives the whole equipment to fly. After reaching the upper part of the spraying range, start the intelligent reversing motor 21 fixedly installed on the top of the connecting support plate 3 to move. The lower output end of the intelligent reversing motor 21 rotates while transmitting the fixed rotating disk 8 fixedly installed on the lower output end. Since the conflicting semicircular rod 9 is fixedly installed on the lower surface of the fixed rotating disk 8, the conflicting semicircular rod 9 rotates synchronously therewith, and contacts the concave conflicting frame 10 in the rotation trajectory of the conflicting semicircular rod 9. Since the concave conflicting frame 10 is of concave design, it drives the fixed connecting rod 8 on the back after being conflicted by the conflicting semicircular rod 9. The lower end of the connected rotating blocking plate 11 moves backward. Since the middle section of the rotating blocking plate 11 is rotatably installed inside the sliding inner groove 12, the upper end of the rotating blocking plate 11 swings in the opposite direction after receiving the resistance at the lower end. The upper end fitting surface of the rotating blocking plate 11 is inside the medicine storage tank 4, and is located at the internal connection between the medicine storage tank 4 and the hydraulic spray pipe 5. The upper end of the rotating blocking plate 11 swings so that the upper end opening of the hydraulic spray pipe 5 is opened to complete the internal connection. When the lower end of the rotating blocking plate 11 swings backward, the return spring 20 fixedly installed on the back is squeezed. When the resisting semicircular rod 9 is out of contact with the concave resisting frame 10, the return spring 20 releases its elastic potential energy to push the upper end of the rotating blocking plate 11 back to its original position again.

[0028] like Figure 1 , Figure 6 , Figure 4The technical solution shown in the figure, in order to solve the problem that the viewing angle of the existing equipment is limited and the adjustment is inconvenient, discloses: the meshing sliding mechanism includes a fixed gear 13, and the fixed gear 13 is fixedly installed at the upper output end of the intelligent reversing motor 21, and two groups of sliding angle plates 6 are installed symmetrically about the center point of the connecting support plate 3, and a driven worm 14 is installed in the middle of the two groups of sliding angle plates 6, the driven worm 14 is in contact with the fixed gear 13, and the outer surface of the driven worm 14 is installed with a passive rotating gear 15, and the passive rotating gear 15 is installed on the outer surface of the driven worm 14. 5 is installed with a meshing gear rod 16 on its outer surface, and a sliding transmission rod 17 is installed on the back of the meshing gear rod 16, a sliding limit frame 18 is installed on the back of the sliding transmission rod 17, and a resisting sliding frame 19 is installed inside the sliding limit frame 18, the resisting sliding frame 19 is fixedly installed on the upper surface of the connecting support plate 3, and a detection camera 7 is installed at the end of the sliding transmission rod 17, the inner surface of the sliding limit frame 18 contacts the outer surface of the resisting sliding frame 19 to form a sliding structure, and the meshing gear rod 16 and the sliding transmission rod 17 are of an integrated design.

[0029] When it is necessary to adjust the detection camera 7 to obtain a larger observation angle, the upper output end of the intelligent reversing motor 21 is started again, so that the fixed gear 13 fixedly installed at the upper output end of the intelligent reversing motor 21 is driven to rotate in a circle. While the fixed gear 13 rotates, the fixed gear 13 drives the driven worm 14 in contact with the outer surface to produce a meshing motion. Since the driven worm 14 is rotatably installed inside the two sets of sliding angle plates 6, the driven worm 14 is driven to rotate reciprocatingly in a circle under the drive of the meshing motion. Since the passive rotating gear 15 is fixedly installed on the outer surface of the driven worm 14, the passive rotating gear 15 is driven to rotate in a circle. The driven rotating gear 15 rotates synchronously, and the rotation of the passive rotating gear 15 drives the meshing gear rod 16 that contacts each other on the side to move downward. The downward movement of the meshing gear rod 16 drives the sliding transmission rod 17 fixedly connected to the lower surface to move synchronously. While the sliding transmission rod 17 slides down, the sliding transmission rod 17 fixedly installed on the back side slides along the outside of the sliding limit frame 18 to produce a limiting effect. The sliding transmission rod 17 is slidably installed inside the connecting support plate 3, and the detection camera 7 is fixedly installed at the end of the sliding transmission rod 17. The detection camera 7 can slide up and down by controlling the forward and reverse rotation of the intelligent reversing motor 21.
