[0002] The performance test structure for spray range of unmanned agricultural drones plays an important role in agriculture, forestry and other fields. The test structure can simulate the spraying effect under different climatic conditions and wind speeds, optimize flight parameters, and in areas with high wind speeds, reduce droplet drift by adjusting the nozzle angle or adding anti-drift additives to ensure the control effect.

[0003] Among the existing publicly available literature, patent publication number CN112595539A discloses a high-voltage electrostatic spraying test bench for agricultural pesticides. This technology realistically simulates the real-time changes in the relative position between the spraying device and crops during farmland spraying operations. It features a novel and reasonable structure, accurate and reliable test data, good consistency with actual operating environments and conditions, and a wide range of applications and strong applicability. However, this technology still has the following shortcomings.

[0004] During performance testing of drone-based agricultural spraying range, the spraying range is mainly affected by wind force, causing it to deviate. However, it is difficult to conduct spraying range performance tests according to different wind positions, resulting in poor test adjustability. Therefore, a spraying range performance test structure is needed. Utility Model Content

The adjustment test component is used to adjust different test distances, and the adjustment test component includes: A sleeve plate is installed on one side of the drone's spray head. A sleeve block is fixed to the lower surface of the sleeve plate, and a support column runs through the inner wall of the sleeve block. The support column is used to guide the movement of the sleeve block. A guide frame is fixed to one end of the sleeve block, and a linkage block is fixed to one end of the guide frame. The blade is rotatably mounted inside the sleeve, and a motor is installed at one end of the blade to drive the blade to rotate.

[0006] In a preferred embodiment, the guide frame is used to guide the movement of the sleeve block, and the vertical cross-sectional shape of the support column is circular.

[0007] In a preferred embodiment, the sleeve plate and the guide frame are slidably connected, and a gap is provided between the linkage block and the sleeve plate.

[0009] In a preferred embodiment, the top of the sleeve is embedded with a threaded bolt, which is used to press and lock onto the support.

[0010] In a preferred embodiment, a pressure pump is installed at the top of the drone spray head, the pressure pump being used to increase the pressure of the spray from the drone spray head.

[0011] In a preferred embodiment, the input end of the pressure pump is connected to a container for holding water.

[0012] In a preferred embodiment, an arc-shaped block is fixed to one side of the linkage block, and a gripping rod is fixed to the upper surface of the container; An arc-shaped rail is installed on the outside of the arc-shaped block, and the arc-shaped rail is fixedly connected to the test chamber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 - Figure 4 The diagram shows a spray range performance test structure, which is equipped with an adjustment test component. The adjustment test component can adjust the position of the wind supply, thereby affecting the offset of the atomization spray range of the UAV spray head 2, and realizing test operations at different parts. The specific structural settings of the adjustment test component are as follows.

[0022] In this embodiment, as Figure 1 - Figure 4 As shown, the system includes a test chamber 1, inside which a drone spray head 2 is installed. An adjustment test assembly is located on one side of the drone spray head 2, used to adjust different test distances. The adjustment test assembly includes: a sleeve plate 3, installed on one side of the drone spray head 2; a sleeve block 4 fixed to the lower surface of the sleeve plate 3; a support column 5 penetrating the inner wall of the sleeve block 4; the support column 5 guiding the movement of the sleeve block 4; a guide frame 6 fixed to one end of the sleeve block 4; and a linkage block 7 fixed to one end of the guide frame 6; and a blade 8 rotatably installed inside the sleeve plate 3; a motor 9 installed at one end of the blade 8, used to drive the blade 8 to rotate. The guide frame 6 guides the movement of the sleeve block 4, and the vertical cross-section of the support column 5 is circular. The sleeve plate 3 and the guide frame 6 are slidably connected, and a gap is provided between the linkage block 7 and the sleeve plate 3.

[0023] In this embodiment, as Figure 3 As shown, a support rod 10 is fixed between the motor 9 and the bottom of the inner wall of the sleeve 3, and the support rod 10 is used to support the motor 9. The support rod 10 supports the motor 9, which greatly improves the stability of the motor 9.

[0024] In this embodiment, as Figure 4As shown, a threaded bolt 11 is embedded at the top of the sleeve block 4, and the bolt 11 is used to press and lock onto the support column 5. By rotating the bolt 11, the bolt 11 can engage with the sleeve block 4 through the thread and lock it, thereby improving the stability of the sleeve block 4 after adjustment.

[0025] In this embodiment, as Figure 1 As shown, a pressure pump 12 is installed at the top of the drone spray head 2. The pressure pump 12 is used to increase the pressure of the spray from the drone spray head 2. The input end of the pressure pump 12 is connected to a container 13, which is used to hold water. By adding water into the container 13, the pressure pump 12 pressurizes the water and injects it into the drone spray head 2, thus achieving the atomized pressurized downward spraying operation.

[0026] When using the spray range performance test structure of this technology, by moving the sleeve plate 3, the sleeve plate 3 drives the sleeve block 4 to move. The sleeve block 4 moves to the left along the outer wall of the support column 5 and simultaneously moves to the left along the inner wall of the guide frame 6. The sleeve plate 3 drives the support rod 10, causing the motor 9 to move. The motor 9 drives the blade 8 to move. By adjusting the distance between the blade 8 and the drone spray head 2, the bolt 11 can be rotated to engage with the sleeve block 4 and lock it in place. The bottom end of the bolt 11 is pressed against the support column 5. By turning on the motor 9, the motor 9 drives the blade 8 to rotate, thereby providing wind power to the bottom of the drone spray head 2. At the same time, water is added into the housing 13 and pressurized by the pressure pump 12 into the drone spray head 2, which then sprays the water downwards in atomized form. The drone spray head 2 is a component used for drone plant protection and can adjust the position of the wind power supply.

[0027] In this embodiment, as Figure 3 - Figure 4 As shown, an arc-shaped block 14 is fixed on one side of the linkage block 7, and a gripping rod 15 is fixed on the upper surface of the housing 13; an arc-shaped rail 16 is installed on the outside of the arc-shaped block 14, and the arc-shaped rail 16 is fixedly connected to the test chamber 1. An arc-shaped groove 17 is opened inside the arc-shaped rail 16, and the arc-shaped groove 17 can be used to guide the arc-shaped block 14 to slide.

[0028] In use, by holding the grip rod 15, the grip rod 15 drives the arc block 14 to move. The arc block 14 moves along the arc groove 17 inside the arc rail 16 in an arc path. Thus, the arc block 14 drives the linkage block 7 to move in an arc path. The linkage block 7 drives the guide frame 6 to move the support column 5 in an arc path. The support column 5 drives the sleeve block 4 to move the sleeve plate 3 in an arc path. The sleeve plate 3 drives the support rod 10 to move the motor 9 in an arc path. The motor 9 drives the blade 8 in an arc path.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
