Description

Technical Field

[0001] The present application relates to the technical field of plant protection UAVs, and in particular to a plant protection and control device for orchards. Background Art

[0002] "CN 213057525 U" discloses "a plant protection drone based on mountain orchard pest control, including a drone body, support columns are connected to both sides of the bottom end of the drone body, and a stabilizing mechanism is connected to the end of the support column away from the drone body... The inner wall surface of the bottom end of the fixed block is provided with an internal thread, and the internal thread is used in conjunction with the external thread on the surface of the screw." It is controlled by a remote control device, the motor rotates, drives the screw to rotate, and makes the screw rise and fall. The liquid medicine tank is provided with a slide groove and a sliding rod to ensure that the spray rack descends smoothly, which is conducive to the delivery of the liquid medicine inside the liquid medicine tank to the spray rack for spraying. The liquid medicine sprays down along the holes on the surface of the spray rack, so that the liquid medicine is sprayed evenly;

[0003] Regarding the above-mentioned related technologies, the inventor believes that although the spraying frame is lifted and lowered by driving the screw rod to rotate through a motor, thus preventing the liquid medicine from directly adhering to the surface of the drone, the motor needs to move synchronously in the process of driving the screw rod to lift and lower, which increases the difficulty of leading out the control line and may affect the overall stability of the drone. In addition, during the spraying process, the liquid medicine is affected by the airflow generated by the drone during flight, and part of the liquid medicine may diffuse upward, thereby causing a potential threat to the drone itself and its control line.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem of synchronous lifting and lowering of the motor, screw and spray rack, the control line of the motor needs to be led out separately, which is easy to be affected by the diffusion of liquid medicine and affects the safety of the drone and the control line.

[0006] The plant protection and control equipment for orchards provided in this application adopts the following technical solution:

[0007] A plant protection and control equipment for orchards, comprising a drone body, a landing bracket, a liquid medicine tank, a lifting component and a spray rack;

[0008] Wherein, the landing bracket is arranged on the lower side of the drone body, and is used for supporting and installing the whole mechanism;

[0009] The liquid medicine tank is arranged on the landing bracket and is used to store the sprayed liquid medicine;

[0010] Several of the lifting assemblies include a slider disposed on the side of the liquid medicine tank, and the slider moves along the Z axis. A folding frame is also disposed on the lower side of the drone body, and the folding frame is connected to the slider, and the slider is used to drive the folding frame to unfold and fold to realize the lifting of the spray frame;

[0011] The spray frame is arranged on the lower side of the folding frame and is used for spraying liquid medicine.

[0012] Preferably, the lifting assembly further comprises a driving component disposed at the lower end of the drone body, for driving the slider to move along the Z axis.

[0013] Preferably, the driving component includes a motor arranged on the drone body, a screw is arranged at the lower end of the motor, and the lower end of the screw is threadedly connected to the slider.

[0014] Preferably, the folding frame includes two connecting units and several folding units, the connecting unit includes two hinged rods, the folding unit includes two folding rods hinged to each other in the middle, two adjacent folding units are hinged to each other, the inner sides of the two connecting units are respectively hinged to the two ends of the folding unit to form a foldable structure, and the slider is connected to the middle hinge point of one of the folding units.

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a plant protection and control device for an orchard. Figure 1-3 A plant protection and control equipment for an orchard includes a drone body 1, a landing bracket 2 is installed on the lower side of the drone body 1, the drone body 1 is supported by the landing bracket 2, a liquid medicine tank 3 is installed on the inner side of the landing bracket 2, and lifting components 4 are installed on both sides of the liquid medicine tank 3 on the drone body 1. The lifting components 4 include a folding frame 404 installed on the drone body 1, and the lower ends of the two folding frames 404 are installed with the same spray frame 5. The foldable folding frame 404 is used to lift and lower, and the overall height of the spray frame 5 is adjusted, and the liquid medicine is sprayed through the spray frame 5.

[0024] Reference Figure 1 The landing bracket 2 is composed of a support frame and a plurality of damping buffers installed at the lower end of the support frame. The support frame is used to support the drone body 1 during take-off and landing, and to install and fix the liquid medicine tank 3.

[0025] Reference Figure 2 The lifting component 4 also includes a motor 401 installed on the drone body 1. A screw 402 is rotatably installed at the lower end of the motor 401. A slider 403 is installed on the screw 402. The slider 403 moves up and down to drive the folding frame 404 to unfold and fold, thereby realizing the lifting of the spray frame 5.

[0026] Reference Figure 3 The folding frame 404 includes two connecting units, a plurality of folding units are hinged inside the two connecting units, and adjacent folding units are hinged to each other, and ends of the two connecting units away from each other are respectively hinged to the drone body 1 and the spray frame 5;

[0027] The connection unit includes two hinged rods 4042, the two hinged rods 4042 are hinged to the corresponding folding units respectively, the ends of the two hinged rods 4042 away from the folding units are hinged to each other, and the drone body 1 and the spray rack 5 are hinged to the corresponding hinged rods 4042 respectively;

[0028] The folding unit includes two folding rods 4041 hinged to each other in the middle, the ends of the two folding rods 4041 are hinged to each other, the outermost four folding rods 4041 are respectively hinged to the corresponding hinged rods 4042, and the slider 403 is connected to the middle hinge point of one of the folding rods 4041. The middle hinge point of the folding rod 4041 is driven to move by the slider 403, so that the folding rod 4041 and the hinged rod 4042 are folded and unfolded, thereby completing the lifting and lowering of the spray rack 5.

[0029] Reference Figure 2 The spray rack 5 includes a spray pipe 501, which is provided with a plurality of spray holes. The spray pipe 501 is sleeved with two fixing blocks 502, which are respectively hinged to the corresponding hinge rods 4042. The spray pipe 501 is connected to the liquid medicine tank 3 through a telescopic hose to ensure smooth supply of liquid medicine.

[0030] The implementation principle of a plant protection and control device for orchards in the embodiment of the present application is as follows: when plant protection and control is required, first, the drone body 1 is controlled to take off and hover above the orchard. Then the motor 401 is controlled to start, drive the screw 402 to rotate, and move the slider 403 downward on the screw 402. The movement of the slider 403 drives the folding frame 404 to unfold, so that the spray frame 5 gradually descends until the predetermined spraying height is reached. At this time, the liquid medicine in the liquid medicine tank 3 is transported to the spray pipe 501 through the pipeline, and sprayed out from the spray hole to cover the plants in the orchard. After the spraying is completed, the motor 401 is reversed to move the slider 403 upward, drive the folding frame 404 to fold, and put away the spray frame 5, so that the drone can perform the next operation or return to the base.
