Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a material box for a plant protection UAV and the plant protection UAV. Background Art

[0002] To facilitate replacement and removal, and to save costs, the feed tanks of current agricultural drones are typically loosely mounted on the aircraft. Once the tank is empty, due to its light weight, rapid descent or sudden flight changes can cause significant relative displacement between the tank and the aircraft due to inertia. This can lead to the tank being struck by the aircraft's propellers, potentially damaging both the aircraft and the tank, and even causing a crash. Utility Model Content

[0003] In view of the above analysis, the embodiments of the present utility model aim to provide a material box for a plant protection drone and a plant protection drone, so as to solve the problem that the material box of the existing plant protection drone is displaced from the aircraft due to inertia, resulting in the material box being hit by the aircraft blades.

[0004] The purpose of this utility model is mainly achieved through the following technical solutions:

[0005] In one aspect of the present invention, a material box for a plant protection drone is provided, comprising a material box body and a spinner, wherein the material box body comprises a first portion and a second portion, and opposite sides of the first portion extend outward to form corner portions;

[0006] The lower portion of the second part relative to the corner portion has a limiting portion; the limiting portion is used to limit the upward movement of the material box body relative to the bracket.

[0007] Furthermore, the limiting portion is a protruding portion, and a smooth arc-shaped surface is provided on the upper portion of the protruding portion.

[0008] Furthermore, the material box body has a support portion, and the support portion includes a first support portion, a second support portion and a third support portion.

[0009] Furthermore, the first support portion and the third support portion are provided with weighing scales; and the second support portion is provided with a buffer component.

[0010] Furthermore, the buffer component has an inclination angle.

[0011] Furthermore, the first supporting portion, the second supporting portion and the third supporting portion are arranged along the circumference of the outer wall of the tank body.

[0012] Furthermore, an inclined portion is provided at the discharge port of the material box body.

[0013] Furthermore, it also includes a material detection unit;

[0014] The material detection unit includes a laser reflection device and a laser emitter;

[0015] The laser reflecting device is arranged on the protruding portion of the material box body, and the laser emitter is arranged opposite to the laser reflecting device.

[0016] Furthermore, the spinning disc is provided with a spinning disc motor, and the laser emitter is electrically connected to the spinning disc motor.

[0017] Another aspect of the present invention provides a plant protection drone, comprising a battery, a bracket, and the aforementioned material box for the plant protection drone;

[0018] The material box body is clamped on the bracket through the corner portion; the battery is arranged on one side of the limiting portion of the material box body; when the material box moves upward, the upper portion of the limiting portion abuts against the bottom end of the battery, forming a limit for the upward movement of the material box;

[0019] The inclination angle of the buffer component is equal to the inclination angle of the bracket.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0021] (1) The material box in the present invention is fixed by the corner part of the first part. Compared with the prior art, the present invention sets a limit part at the lower part of the second part. When the material box moves upward, it forms a limit for the upward movement of the material box, thereby avoiding the risk that the material in the material box is used up, the weight of the material box is reduced, and the flight posture of the plant protection drone suddenly changes, causing the material box to move upward and break away from the bracket and collide with the blades. In the present invention, there is no need to set other additional components outside the material box or the bracket, which meets the weight reduction goal of the drone, and the material box is easy to disassemble.

[0022] (2) The upper surface of the protrusion is set to a smooth arc shape to avoid a rigid collision with the battery and damage to the material box.

[0023] (3) A support portion is provided circumferentially on the material box body for supporting the material box body; the first support portion, the second support portion and the third support portion are provided circumferentially along the outer wall of the material box body to limit the horizontal movement of the material box.

[0024] (4) A sloped portion is provided at the bottom of the bin near the discharge port. When the bin is discharging materials, the materials automatically slide down the sloped portion due to gravity, thus reducing the accumulation of materials in the bin.

[0025] (5) In order to promptly determine the remaining material, stop the spinner at the bottom of the material box, and prevent the spinner from idling, the material box of the present invention is provided with a material detection unit. When the material inside the material box is emptied to a certain extent, the laser reflection device can reflect the received laser back to the laser transmitter, generate material detection information, and promptly send a prompt to the spinner motor to stop working.

[0026] (6) A buffer component is provided in the second support portion to provide cushioning when the container is temporarily separated from the drone's support and then falls back, so as to prevent the container from directly contacting the drone's fuselage and causing damage to the container. To achieve the best buffering effect, the bottom surface of the buffer component has an inclination angle equal to that of the support, so that the buffer component fits closely with the support when falling.

[0027] In the present invention, the above-mentioned technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of the present invention will be described in the following content, and some advantages will become apparent from the description or be understood through practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the contents particularly pointed out in the text and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0037] A specific embodiment of the present invention is as follows Figure 1-Figure 3 As shown, a material box for a plant protection drone is disclosed, including a material box body 1 and a spinner 2.

[0038] To reduce the weight of the drone and facilitate replacement of the tank body 1, a mounting opening for the tank is formed on the upper portion of the bracket 4. During installation, the tank is inserted into the drone's bracket 4. The tank body 1 is designed in a funnel shape, with a larger upper portion and a smaller lower portion. The tank body 1 comprises a first portion and a second portion. The outer diameter of the first portion is larger than that of the bracket 4, while the outer diameter of the second portion is smaller than that of the bracket 4. Corners extend outward from opposite sides of the first portion, and the tank is secured to the bracket 4 via these corners, limiting its downward movement.

[0039] When the container is clamped to the bracket 4, the contact area between the container body 1 and the bracket 4 forms a support portion 11. This support portion 11 comprises a first support portion 111, a second support portion 112, and a third support portion 113. Two first support portions 111 are provided, and they are symmetrically arranged. These first, second, and third support portions 111, 112, 113 are arranged circumferentially along the outer wall of the container body 1.

[0040] A weighing scale is provided on the bracket 4 at locations corresponding to the first supporting portion 111 and the third supporting portion 113, which is used to weigh the material box body 1. Therefore, the first supporting portion 111 and the third supporting portion 113 in contact with the weighing scale are rigidly provided. Furthermore, a buffer component 1121 is provided in the second supporting portion 112, which is used to achieve buffering when the material box body 1 temporarily detaches from the bracket 4 of the drone and falls back again, so as to prevent the material box body 1 from directly contacting the fuselage and causing damage to the material box body 1. Exemplarily, there are two pairs of second supporting portions 112 and buffer components 1121, and they are symmetrically arranged on two opposite sides of the material box. In this embodiment, the buffer component 1121 is a silicone pad. As an alternative to this embodiment, it can also be a rubber pad or other elastic material. Specifically, in order to achieve the best buffering effect, the bottom surface of the buffer component 1121 has an inclination angle that matches the angle of the bracket 4, so that the buffer component 1121 fits the bracket 4 when falling.

[0041] The container is inserted into bracket 4, with horizontal and downward movement limits formed on support 11. This limits the container's horizontal and downward movement. When the container's contents are depleted and its weight decreases, causing the drone's flight attitude to change, the container will move upward and away from bracket 4. At this point, the container could fly out and collide with the propeller blades, potentially damaging the drone or the container, leading to a grounded drone or other malfunction.

[0042] Furthermore, in order to prevent the material box from escaping from the bracket 4 upward, a limiting portion 12 is provided at the lower portion of the material box body 1 on the other side relative to the corner portion. Figure 4 and Figure 5 As shown, the stopper 12 corresponds to the lower portion of the bottom end of the battery 3 adjacent to the container. In this embodiment, the stopper 12 is illustratively a protrusion. The protrusion is integral with the container body 1. When the container moves upward, the protrusion moves upward with it. At this point, the upper end of the protrusion abuts the bottom end of the battery 3, limiting the container's upward movement.

[0043] In this embodiment, the feed box is secured to the bracket 4 via a corner portion, which limits the horizontal and downward displacement of the feed box. Compared to the prior art, this embodiment provides a limiter 12 at the bottom of the feed box body 1. When the feed box moves upward, it abuts against the bottom end of the battery 3, limiting the feed box's upward movement. This avoids the risk of the feed box moving upward and separating from the bracket 4 and colliding with the blades when the material in the feed box is used up and the weight of the feed box decreases. In this embodiment, no additional components are required on the outside of the feed box, which meets the drone's weight reduction goals, and the feed box is easy to disassemble.

[0044] Furthermore, the upper surface of the protrusion is configured to be a smooth arc to avoid a rigid collision with the battery 3 and damage to the material box.

[0045] Furthermore, an inclined portion 13 is provided near the discharge port at the bottom of the material box body 1. When the material box is discharged, the material automatically slides down along the inclined portion 13 due to gravity, reducing the backlog of materials in the material box.

[0046] To promptly determine the remaining material, stop the spinning disc 2 at the bottom of the bin body, and prevent it from idling, the bin is equipped with a material detection unit 14. This unit includes a laser emitter 142 and a laser reflector 141. The laser reflector 141 is positioned on a protruding portion of the bin body 1, with the laser emitter 142 positioned opposite the laser reflector 141. Preferably, the laser emitter 142 and the laser reflector 141 are located on the same horizontal plane.

[0047] The spinning disc 2 is provided with a spinning disc motor. The spinning disc motor is electrically connected to the laser emitter 142. When the material inside the material box is emptied to a certain level, the laser reflection device 141 can reflect the received laser back to the laser emitter 142, generating material detection information and promptly sending a prompt to the spinning disc motor to stop working.

[0048] The embodiment of the present utility model further provides a plant protection drone, comprising a battery 3, a bracket 4 and the material box for the plant protection drone in the above embodiment.

[0049] The container body 1 is secured to the bracket 4 via its corners. The contact points between the container body 1 and the bracket are the first support 111, the second support 112, and the third support 113. The battery 3 is mounted on the bracket 4, near the retaining portion of the container body 1. When the container moves upward, the top of the protrusion abuts the bottom of the battery 3, limiting the container's position.

[0050] Compared with the prior art, the advantages of the plant protection drone of the embodiment of the present invention are the same as the advantages of the material box for the plant protection drone mentioned above, and will not be repeated here.

[0051] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
