Description

Technical Field

[0001] The present invention relates to the technical field of plant protection UAVs, and in particular to a machine arm quick-detachable structure of a plant protection UAV and a use method thereof. Background Art

[0002] The plant protection UAV 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. It can spray pesticides, seeds, powders, etc. through ground remote control or navigation flight control.

[0003] The arms and fuselage of the agricultural drone are the main structures of the flight platform. The flight and lifting of the drone are controlled by the fan blades on the arms.

[0004] The existing arms and drones are usually connected by multiple screws. When the arms need to be disassembled and replaced, multiple screws need to be removed, which makes the actual disassembly process time-consuming. In addition, during the disassembly process, many screws are prone to fall off or are not installed firmly, making it impossible for the plant protection drone to work normally. Therefore, we propose a quick-disassembly structure for the arms of the plant protection drone. Summary of the invention

The upper surface of the clamping seat is connected to a nut seat, and the nut seat is slidably connected to the inner wall of the movable seat.

[0018] Preferably, a bidirectional screw is rotatably connected to the inner wall of the movable seat, and the two nut seats are threadedly connected to the outer surface of the nut seat.

[0023] Preferably, the method comprises the following steps:

[0024] S1: When the four disassembly arms connected to the outer surface of the fixing base need to be quickly disassembled and replaced, since the motor fixedly connected to one end of the disassembly arm has its connecting wire connected to the control element installed inside the mounting base, it is necessary to first unplug the plug to separate the motor from the fixing base.

[0025] S2: Since the connecting wire is fixed to the sides of the fixed sleeve and the movable seat under the action of the extrusion seat, the extrusion seats on the sides of the movable seat and the fixed sleeve are pulled respectively, so that the extrusion seat drives the slider fixedly connected to its upper surface to slide, so that the slider slides on the inner wall of the placement seat through the limit rod. Under the movement of the extrusion seat, the spring fixedly connected to the slider is compressed, and the connecting wire can be taken out at the same time, so that the connecting wire is separated from the movable seat and the fixed sleeve.

[0026] S3: When all the connecting wires are taken out, the extrusion seat can be released. Under the action of the spring, the extrusion seat returns to the starting position. When installing and disassembling the machine arm, the above-mentioned reverse movement can be performed, so that the connecting wires are stored on the sides of the movable seat and the fixed sleeve block, which is convenient for arranging the connecting wires.

[0027] S4: At this time, by rotating the bidirectional screw rod, the two nut seats connected by threads on the outer surface of the bidirectional screw rod move in the opposite direction, so that the movement of the nut seat drives the clamping seat fixedly connected to the lower surface of the nut seat to move accordingly, so that the two clamping seats move in the opposite direction and separate from the disassembly arm.

[0028] S5: At this time, the rotating seat is rotated to move the adjusting screw connected by thread on the inner wall of the rotating seat, so that the adjusting screw drives the multiple plug blocks fixedly connected to its outer surface to move, thereby separating the plug blocks from the limit blocks fixedly connected to the inner wall of the fixed machine arm. At this time, the disassembly machine arm can be rotated to drive the adjusting screw and the plug blocks to rotate, so that the disassembly machine arm can drive the adjusting screw and the plug blocks to slide outward along the adjacent inner walls of the limit blocks, thereby separating the fixed machine arm from the disassembly machine arm, thereby achieving the effect of quickly disassembling the disassembly machine arm.

[0029] S6: When it is necessary to install and disassemble the machine arm, first pass the disassembly machine arm through the two clamping seats, and then insert the plug block fixedly connected to the outer surface of the adjusting screw rod into the inner wall of the fixed machine arm, and by rotating the disassembly machine arm, the plug block is overlapped with the slot on the inner wall of the limit block. At this time, the disassembly machine arm can be pulled to make the plug block inserted into the inner wall of the limit block, and then by rotating the rotating seat, the adjusting screw rod is moved, so that the disassembly machine arm and the rotating seat are moved relative to the adjusting screw rod, so that the rotating seat is moved closer to the fixed machine arm, until the fixed machine arm and the disassembly machine arm squeeze the rotating seat, so that the disassembly machine arm and the fixed machine arm are connected.

[0030] S7: At this time, according to the length of the disassembly arm, the adjusting seat can be driven to rotate by rotating the rotating block, so that the adjusting seat drives the connecting block fixedly connected to the outer surface to move along the supporting rod, so that the four rotating rods move and rotate, and under the movement of the four rotating rods, the four moving seats move at the same time, so that the moving seat drives the clamping seat to move until the clamping seat is in a suitable position on the outer surface of the disassembly arm, so as to support the disassembly arm.

[0031] S8: When the clamping seat moves to the appropriate position, the bidirectional screw is rotated to perform the above-mentioned opposite movement, driving the two clamping seats to move toward each other, so that the two clamping seats are squeezed with the disassembly arm, so that the moving seat and the disassembly arm are fixed, thereby further fixing the position of the disassembly arm. By performing the same movement as above, the disassembly and installation of multiple disassembly arms can be completed without removing multiple screws, so that the installation and disassembly speed is faster. At the same time, since the screws are not removed, there is no situation where the screws are lost and the installation cannot be completed, and the threads are not tightened and the installation is not firm.

[0032] The present invention discloses a quick-detachable arm structure of a plant protection UAV and a use method thereof, which has the following beneficial effects:

[0033] 1. The quick-release structure and use method of the arm of the plant protection drone first separate the movable seat supporting the disassembly arm from the disassembly arm through the connecting assembly. At this time, under the action of the quick-release assembly, the fixed arm and the disassembly arm are separated and not fixed, so that the disassembly arm can be quickly removed from the fixed arm without removing multiple screws, so that the installation and disassembly speed is faster. At the same time, since the screws are not removed, there is no possibility of installation failure due to the loss of screws.

DETAILED DESCRIPTION

[0049] The embodiment of the present invention discloses a quick-detachable arm structure of a plant protection UAV and a method for using the same.

[0050] like Figure 1 , Figure 2 and Figure 4 As shown, it includes a fixing base 1, two supporting frames 2, four fixing machine arms 3 and four disassembling machine arms 4, a protective cover 102 is arranged on the upper surface of the fixing base 1, a mounting base 101 is arranged on the lower surface of the fixing base 1 for mounting control elements, the supporting frames 2 are arranged on the lower surface of the fixing base 1, and the fixing machine arms 3 are arranged on the inner wall of the fixing base 1;

[0051] The disassembly arm 4 is connected to the fixed arm 3, and is connected to the outer surface of the fixed seat 1 through the fixed arm 3. One end of the fixed arm 3 is connected to a connecting seat 301, and the connecting seat 301 is connected to the fixed seat 1. A fixed sleeve 302 is provided on the outer surface of the fixed arm 3, and the placement seat 8 is located on the outer surface of the fixed arm 3 by connecting with the fixed sleeve 302.

[0052] The upper surface of the fixed sleeve block 302 is connected with a connecting rod 303, and the other end of the connecting rod 303 is connected to the fixed seat 1. Under the action of the connecting rod 303, the connecting rod 303 supports the fixed machine arm 3. One end of the disassembly machine arm 4 is provided with a motor 401, and the upper surface of the motor 401 is connected with a fan blade 402;

[0053] When the four disassembly arms 4 connected to the outer surface of the fixing base 1 need to be quickly disassembled and replaced, since the motor 401 fixedly connected to one end of the disassembly arm 4 has a connection line connected to the control element installed inside the mounting base 101, it is necessary to first unplug the plug to separate the motor 401 from the fixing base 1;

[0054] Under the action of the extrusion assembly, the connection wires arranged and fixed on the sides of the movable seat 5 and the fixed sleeve block 302 are taken out, which is convenient for the subsequent disassembly of the disassembly arm 4. Through the connection assembly, the movable seat 5 supporting the disassembly arm 4 is not fixed to the disassembly arm 4 under the action of the connection assembly.

[0055] At this time, under the action of the quick-release assembly, the fixed machine arm 3 and the disassembly machine arm 4 are separated and not fixed, so that the disassembly machine arm 4 can be quickly disassembled from the fixed machine arm 3 without removing multiple screws, so that the installation and disassembly speed is faster. At the same time, since the screws are not removed, there is no possibility of losing the screws and causing the installation to fail.

[0056] When it is necessary to install the disassembly arm 4, the disassembly arm 4 is first plugged into the inner wall of the fixed arm 3, and then the disassembly arm 4 is connected to the fixed arm 3 through the quick release assembly. At the same time, according to the length of the disassembly arm 4, the movable seat 5 can be moved to a suitable position on the outer surface of the disassembly arm 4 under the action of the adjustment assembly, so as to support the disassembly arm 4.

[0057] At this time, under the action of the connecting assembly, the position of the disassembly arm 4 is further fixed, and the same movement as above is performed to complete the disassembly and installation of multiple disassembly arms 4, avoiding the situation where the thread is not tightened and the installation is not firm.

[0058] like Figure 8 and Fig. 9 As shown, the outer surface of the disassembly arm 4 is provided with a connection assembly, which includes a moving seat 5 and two clamping seats 501. The moving seat 5 is arranged on the outer surface of the disassembly arm 4 through the two clamping seats 501, and is used to fix the disassembly arm 4. The two clamping seats 501 are connected to the outer surface of the disassembly arm 4;

[0059] The upper surface of the clamping seat 501 is connected with a nut seat 502, which is slidably connected to the inner wall of the moving seat 5, and the inner wall of the moving seat 5 is rotatably connected with a bidirectional screw rod 503, and the two nut seats 502 are threadedly connected to the outer surface of the nut seat 502, and the two clamping seats 501 are connected and separated from the disassembly arm 4 by the bidirectional screw rod 503;

[0060] By rotating the bidirectional screw rod 503, the two nut seats 502 on the outer surface of the bidirectional screw rod 503 move in opposite directions. The movement of the nut seats 502 drives the clamping seats 501 on the lower surface of the nut seats 502 to move accordingly, so that the two clamping seats 501 move in opposite directions and separate from the disassembly arm 4.

[0061] When it is necessary to support the installation of the disassembly arm 4, the bidirectional screw rod 503 is rotated to perform the above-mentioned opposite movement, driving the two clamping seats 501 to move toward each other, so that the two clamping seats 501 are squeezed with the disassembly arm 4, so that the moving seat 5 and the disassembly arm 4 are fixed, thereby achieving the effect of supporting the disassembly arm 4.

[0062] like Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, a quick release assembly is provided between the fixed machine arm 3 and the dismantling machine arm 4, and the quick release assembly includes an adjusting screw rod 6, a plurality of plug blocks 601 and a plurality of limit blocks 602, and the fixed machine arm 3 and the dismantling machine arm 4 are connected by plugging the plurality of plug blocks 601 and the limit blocks 602;

[0063] The adjusting screw rod 6 is arranged on the inner wall of the disassembling arm 4, one end of the adjusting screw rod 6 is plugged into the inner wall of the fixed arm 3, a plurality of inserting blocks 601 are arranged on the outer surface of the adjusting screw rod 6, a plurality of limiting blocks 602 are arranged on the inner wall of the fixed arm 3, and a plurality of inserting blocks 601 are plugged into the inner walls of the corresponding limiting blocks 602;

[0064] A rotating seat 603 is rotatably connected to the inner wall of the disassembly arm 4, and the rotating seat 603 is connected to the outer surface of the adjusting screw rod 6. The adjusting screw rod 6 is moved by controlling the rotating seat 603, so that the plug block 601 is plugged into the limit block 602, thereby connecting the fixed arm 3 with the disassembly arm 4;

[0065] By rotating the rotating seat 603, the adjusting screw rod 6 on the inner wall of the rotating seat 603 moves, so that the adjusting screw rod 6 drives the multiple plug blocks 601 on its outer surface to move, so that the plug blocks 601 are separated from the limit blocks 602. At this time, the machine arm 4 can be rotated and disassembled, driving the adjusting screw rod 6 and the plug blocks 601 to rotate;

[0066] The disassembly arm 4 can drive the adjusting screw rod 6 and the plug block 601 to slide outward along the inner wall of the adjacent limit block 602, so that the fixed arm 3 is separated from the disassembly arm 4, thereby achieving the effect of quickly disassembling the disassembly arm 4. When the disassembly arm 4 needs to be installed, the disassembly arm 4 is first passed through the two clamping seats 501, and then the adjusting screw rod 6 is plugged into the inner wall of the fixed arm 3;

[0067] Then, by rotating the disassembly arm 4, the plug block 601 is overlapped with the slot on the inner wall of the limit block 602. At this time, the disassembly arm 4 can be pulled to make the plug block 601 inserted into the inner wall of the limit block 602. Then, by rotating the rotating seat 603, the rotating seat 603 is moved closer to the fixed arm 3 until the fixed arm 3 and the disassembly arm 4 squeeze the rotating seat 603, so that the disassembly arm 4 and the fixed arm 3 are connected.

[0068] like Figure 3 As shown, the upper surface of the fixed seat 1 is provided with an adjustment assembly, the adjustment assembly includes a support rod 7 and four rotating rods 704, the support rod 7 is provided on the upper surface of the fixed seat 1, the outer surface of the disassembly arm 4 is threadedly connected with an adjustment seat 701, and the upper surface of the adjustment seat 701 is provided with a rotating block 702;

[0069] The outer surface of the rotating block 702 is provided with two connecting blocks 703, and the inner walls of the two connecting blocks 703 are rotatably connected to two rotating rods 704, and the other ends of the rotating rods 704 are connected to the moving seat 5, and the disassembly arm 4 is supported by the rotating rods 704;

[0070] By rotating the rotating block 702, the adjusting seat 701 is driven to rotate, so that the adjusting seat 701 drives the connecting block 703 on the outer surface to move along the supporting rod 7, so that the rotating rod 704 moves and rotates;

[0071] When the rotating rod 704 moves, the movable seat 5 moves, thereby the movable seat 5 drives the clamping seat 501 to move, until the clamping seat 501 is at a suitable position on the outer surface of the disassembly arm 4, so as to support the disassembly arm 4.

[0072] like Fig. 9 and Fig.11 As shown, the outer surfaces of the fixed machine arm 3 and the movable seat 5 are both provided with an extrusion assembly, and the extrusion assembly includes a placement seat 8 and an extrusion seat 801. A limit rod 804 is provided on the inner wall of the placement seat 8, and a slider 802 is provided on the upper surface of the extrusion seat 801;

[0073] The extrusion seat 801 is slidably connected to the outer surface of the limiting rod 804 through the slider 802. The outer surface of the limiting rod 804 is sleeved with a spring 803. The two ends of the spring 803 are respectively connected to the slider 802 and the placement seat 8.

[0074] By pulling the extrusion seat 801 on the side of the movable seat 5 and the fixed sleeve block 302, the extrusion seat 801 drives the slider 802 to slide, so that the slider 802 slides on the inner wall of the placement seat 8 through the limit rod 804, and the spring 803 is compressed under the movement of the extrusion seat 801;

[0075] At the same time, the connecting wire can be taken out, so that the connecting wire is separated from the movable seat 5 and the fixed sleeve block 302, and the extrusion seat 801 is loosened. Under the action of the spring 803, the extrusion seat 801 returns to the starting position. When installing and disassembling the arm 4, the above-mentioned reverse movement can be performed, so that the connecting wire is stored on the side of the movable seat 5 and the fixed sleeve block 302, which is convenient for organizing the connecting wire.

[0076] Working principle: When the four disassembly arms 4 connected to the outer surface of the fixing seat 1 need to be quickly disassembled and replaced, since the motor 401 fixedly connected to one end of the disassembly arm 4 has a connection line connected to the control element installed inside the mounting seat 101, it is necessary to first unplug the plug to separate the motor 401 from the fixing seat 1;

[0077] Since the connecting wire is fixed to the sides of the fixed sleeve 302 and the movable seat 5 under the action of the extrusion seat 801, the extrusion seat 801 on the sides of the movable seat 5 and the fixed sleeve 302 is pulled respectively, so that the extrusion seat 801 drives the slider 802 fixedly connected to its upper surface to slide, so that the slider 802 slides on the inner wall of the placement seat 8 through the limiting rod 804;

[0078] When the extrusion seat 801 moves, the spring 803 fixedly connected to the slider 802 is compressed, and the connecting wire can be taken out, so that the connecting wire is separated from the movable seat 5 and the fixed sleeve block 302. When all the connecting wires are taken out, the extrusion seat 801 can be released.

[0079] Under the action of the spring 803, the extrusion seat 801 returns to the initial position. When installing or removing the machine arm 4, the above-mentioned reverse movement can be performed, so that the connecting wires are stored on the sides of the movable seat 5 and the fixed sleeve block 302, which is convenient for arranging the connecting wires.

[0080] At this time, by rotating the bidirectional screw rod 503, the two nut seats 502 threadedly connected to the outer surface of the bidirectional screw rod 503 move in the opposite direction, so that the movement of the nut seat 502 drives the clamping seat 501 fixedly connected to the lower surface of the nut seat 502 to move accordingly, so that the two clamping seats 501 move in the opposite direction and separate from the disassembly arm 4;

[0081] At this time, the rotating seat 603 is rotated to move the adjusting screw rod 6 threadedly connected to the inner wall of the rotating seat 603, so that the adjusting screw rod 6 drives the multiple plug blocks 601 fixedly connected to its outer surface to move, so that the plug blocks 601 are separated from the limit blocks 602 fixedly connected to the inner wall of the fixed machine arm 3;

[0082] At this time, the disassembly arm 4 can be rotated to drive the adjusting screw rod 6 and the insert block 601 to rotate, so that the disassembly arm 4 can drive the adjusting screw rod 6 and the insert block 601 to slide outward along the inner wall of the adjacent limit block 602, so that the fixed arm 3 is separated from the disassembly arm 4, thereby achieving the effect of quickly disassembling the disassembly arm 4;

[0083] When the disassembly arm 4 needs to be installed, the disassembly arm 4 is first passed through the two clamping seats 501, and then the plug block 601 fixedly connected to the outer surface of the adjusting screw 6 is plugged into the inner wall of the fixed arm 3, and the disassembly arm 4 is rotated so that the plug block 601 coincides with the slot on the inner wall of the limit block 602. At this time, the disassembly arm 4 can be pulled so that the plug block 601 is plugged into the inner wall of the limit block 602;

[0084] Then, by rotating the rotating seat 603, the adjusting screw rod 6 is moved, so that the disassembling arm 4 and the rotating seat 603 are moved relative to the adjusting screw rod 6, so that the rotating seat 603 is moved closer to the fixed arm 3, until the fixed arm 3 and the disassembling arm 4 squeeze the rotating seat 603, so that the disassembling arm 4 and the fixed arm 3 are connected;

[0085] First, the protective cover 102 is separated from the fixing base 1 by removing the bolts. At this time, according to the length of the disassembled machine arm 4, the adjusting base 701 can be driven to rotate by rotating the rotating block 702, so that the adjusting base 701 drives the connecting block 703 fixedly connected to the outer surface to move along the supporting rod 7, so that the four rotating rods 704 move and rotate;

[0086] Under the movement of the four rotating rods 704, the four moving seats 5 move simultaneously, so that the moving seats 5 drive the clamping seat 501 to move until the clamping seat 501 is at a suitable position on the outer surface of the disassembly arm 4, so as to facilitate supporting the disassembly arm 4;

[0087] When the clamping seat 501 moves to a suitable position, the bidirectional screw rod 503 is rotated to perform the above-mentioned opposite movement, driving the two clamping seats 501 to move toward each other, so that the two clamping seats 501 are squeezed with the disassembly arm 4, so that the moving seat 5 is fixed with the disassembly arm 4, thereby further fixing the position of the disassembly arm 4;

[0088] By performing the same movements as above, the disassembly and installation of multiple disassembly arms 4 can be completed without removing multiple screws, so that the installation and disassembly speed is faster. At the same time, since the screws are not removed, there is no situation where the screws are lost and the installation cannot be completed, and the threads are not tightened and the installation is not firm.

[0089] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
