Technical Field

[0001] The utility model relates to the technical field of agricultural unmanned aerial vehicles, in particular to a pesticide-free automatic return unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. With the continuous development of drone applications, they are also widely used in the agricultural field. Among them, pesticide spraying is one of the most widely used applications of agricultural drones. It has the characteristics of precise operation, high efficiency and environmental protection, intelligence, and simple operation, which can save farmers a lot of labor costs.

[0003] However, after the existing agricultural spraying drone has finished spraying the pesticide in the water tank, it is unable to inform the operator and the drone, and the drone will continue to fly along the installed route, which not only wastes time and the drone's electricity, but also easily causes some crops to be sprayed with pesticides for the second time or not sprayed with pesticides.

[0004] To this end, we provide a drug-free automatic return drone to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a drug-free automatic return drone.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drug-free automatic return drone, comprising a drone, a water pipe is arranged at the lower end of the drone's flight wing, a water pump is arranged at the lower end of the drone, the drainage end of the water pump is connected to the water pipe, a water tank is arranged at the lower end of the drone, a mounting plate is fixedly connected to the upper end of the water tank, the water tank is fixed to the lower end of the drone by passing bolts through the mounting plate, a groove is arranged at the lower end of the water tank, the pumping head is located in the groove, a pointed head is arranged at the front end of the water tank, the pointed head is streamlined, a detection content mechanism is arranged in the water tank, the detection content mechanism comprises a detection rod, and the outer end of the detection rod is slidably connected to a floating rod A floating block, wherein both the upper and lower ends of the floating block are arc groove-shaped, a signal transmitter is arranged at the upper end of the detection rod, a full-load press bead is arranged in the detection rod, a warning press bead is arranged in the detection rod, and an unloaded press bead is arranged in the detection rod. The full-load press bead, the warning press bead and the unloaded press bead have the same structure and are all movably connected in the detection rod. A push rod is fixedly connected to the rear end of the unloaded press bead, the push rod is movably connected in the detection rod, a pressing head is fixedly connected to the rear end of the push rod, a spring is arranged at the outer end of the push rod, the spring is fixedly connected to the detection rod and the unloaded press bead, a contact rod is fixedly connected in the detection rod, and the contact rod is connected to the signal transmitter.

[0007] Furthermore, a spray head is fixedly connected to the lower end of the water pipe, a mounting ring is fixedly connected to the outer end of the water pipe, and the mounting ring is fixedly connected to the lower end of the flying wing of the UAV.

[0008] Furthermore, a pumping head is fixedly connected to the lower end of the water pump, and the pumping head is located in the water tank.

[0009] Compared with the existing technology, the drug-free automatic return drone has the following beneficial effects:

[0010] 1. The utility model is provided with a detection content mechanism in the water tank. When the medicine in the water tank is sprayed, a signal is sent to the remote control end. While reminding the operator, the drone will automatically return to the home position to replace the water tank or replenish the medicine. Specifically, the floating block has a relatively small density and can float on the upper surface of the medicine solution. As the medicine solution is sprayed, the floating block follows it to fall. When the medicine is sprayed, the floating block will squeeze the empty pressing bead. The empty pressing bead is compressed and retracts into the detection rod. The pressing head can be pushed by the push rod so that the pressing head and the contact The touch rod contacts, thereby generating a signal and transmitting it to the signal transmitter. The signal transmitter receives the signal and transmits it to the remote control end and the drone, thereby informing the operator that the medicine in the water tank has been sprayed and causing the drone to return automatically. This solves the problem that after the existing agricultural spraying drone has finished spraying the medicine in the water tank, it cannot inform the operator and the drone, and the drone will continue to fly along the installed route, which not only wastes time and the drone's electricity, but also easily causes some crops to be sprayed with the medicine for the second time or without being sprayed with the medicine.

[0011] 2. The utility model connects the water tank bolts to the lower end of the drone, which can be disassembled and easily replaced, thereby reducing the waiting time for adding medicine and improving work efficiency. By providing an early warning press bead in the detection rod, when the medicine is about to be sprayed out, an early warning message can be issued to remind the operator to plan a route for the drone to shorten the return distance and reduce the return time, thereby improving work efficiency in disguise. By providing a groove at the lower end of the water tank, the water pump head of the water pump is located in the groove, so that the medicine in the water tank can be completely sprayed out to avoid residual medicine in the water tank.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-6 As shown, the utility model provides a technical solution: a drug-free automatic return drone, including a drone 1, a water pipe 2 is arranged at the lower end of the flight wing of the drone 1, the length of the water pipe 2 is slightly shorter than the flight wing of the drone 1, and a spray head 201 is fixedly connected to the lower end of the water pipe 2. The spray head 201 is arranged at the outer position of both ends of the water pipe 2, and can spray the medicine in the water pipe 2 evenly without spraying it on the drone 1. The outer end of the water pipe 2 is fixedly connected to a mounting ring 202, and the mounting ring 202 is fixedly connected to the lower end of the flight wing of the drone 1, and is used to install and fix the water pipe 2.

[0021] A water pump 3 is provided at the lower end of the drone 1, and a water tank 4 is provided at the lower end of the drone 1. A pumping head 301 is fixedly connected to the lower end of the water pump 3. The drainage end of the water pump 3 is connected to the water pipe 2. When the water pump 3 is started, the pumping head 301 will extract the medicine in the water tank 4 and inject it into the water pipe 2, so that the water pipe 2 can provide the medicine solution to the spray head 201.

[0022] A groove 402 is provided at the lower end of the water tank 4, and the groove 402 is the lowest end of the bottom of the water tank 4, so that the medicine in the water tank 4 will eventually gather in the groove 402, and the pumping head 301 is located in the groove 402, so that the medicine in the water tank 4 can be completely extracted to avoid residual medicine in the water tank 4, and a mounting plate 401 is fixedly connected to the upper end of the water tank 4, and the water tank 4 is fixed to the lower end of the drone 1 by bolts passing through the mounting plate 401, so that the water tank 4 can be disassembled and replaced conveniently, which can reduce the waiting time for adding medicine and improve work efficiency. A pointed head 403 is provided at the front end of the water tank 4, and the pointed head 403 is streamlined, which can reduce wind resistance and improve the range of the drone 1.

[0023] A detection content mechanism 5 is provided in the water tank 4, and the detection content mechanism 5 is used to detect the remaining amount of medicine in the water tank 4. The detection content mechanism 5 includes a detection rod 501, and a full-load pressing bead 504, a warning pressing bead 505, and an empty-load pressing bead 506 are provided in the detection rod 501. The three have the same structure and are movably connected in the detection rod 501. A floating block 502 is slidably connected to the outer end of the detection rod 501. The floating block 502 has a relatively small density and can float on the upper surface of the medicine solution. As the medicine solution is sprayed, the floating block 502 can follow it to fall. The upper and lower ends of the floating block 502 are both arc groove-shaped, so that the floating block 502 can squeeze the full-load pressing bead 504, the warning pressing bead 505, and the empty-load pressing bead 506.

[0024] The rear end of the no-load pressing bead 506 is fixedly connected to a push rod 507, and the push rod 507 is movably connected to the detection rod 501. The rear end of the push rod 507 is fixedly connected to a pressing head 508. A spring 509 is provided at the outer end of the push rod 507. The spring 509 is fixedly connected to the detection rod 501 and the no-load pressing bead 506. The spring 509 is used to provide elastic force for the no-load pressing bead 506, so that the no-load pressing bead 506 can automatically rebound and reset. A contact rod 5010 is fixedly connected to the detection rod 501, and a signal transmitter 503 is provided at the upper end of the detection rod 501. The contact rod 5010 is electrically connected to the signal transmitter 503. When the floating block 502 squeezes the empty pressing bead 506, it means that the medicine in the water tank 4 has been sprayed out. At this time, the pressing head 508 will contact the contact rod 5010 to trigger the signal. The contact rod 5010 transmits the signal to the signal transmitter 503 through its own conduction. The signal transmitter 503 receives the signal and transmits the signal to the remote control end and the drone 1. Similarly, when the floating block 502 squeezes the full-load pressing bead 504, it means that the water tank 4 is full of medicine and can transmit the signal to the operator. When the floating block 502 squeezes the warning pressing bead 505, it means that the medicine in the water tank 4 is about to be sprayed out.

[0025] Working principle: The water tank 4 is bolted to the lower end of the drone 1 through the mounting plate 401, and the water pump head 301 of the water pump 3 is inserted into the groove 402 at the lower end of the water tank 4. When spraying the medicine, the water pump 3 is started, and the water pump head 301 will extract the medicine in the water tank 4 and inject it into the water pipe 2. The spray head 201 can spray the medicine evenly;

[0026] Since the floating block 502 has a relatively small density, it can float on the upper surface of the pharmaceutical solution. As the pharmaceutical solution is sprayed, the floating block 502 will follow it down. When the floating block 502 squeezes the warning pressing bead 505, the signal transmitter 503 can send a signal to remind the operator that the medicine in the water tank 4 is about to be sprayed out. When the floating block 502 squeezes the no-load pressing bead 506, the no-load pressing bead 506 is pressed and retracts into the detection rod 501, and can push the pressing head 508 through the push rod 507 to make the pressing head 508 contact with the contact rod 5010, so that the contact rod 5010 will generate a signal and transmit the signal to the signal transmitter 503 through itself. The signal transmitter 503 receives the signal and transmits the signal to the remote control end and the drone 1, thereby informing the operator that the medicine in the water tank 4 has been sprayed out and the drone 1 automatically returns.
