- 1 SPRAYING DEVICE FOR UNMANNED AERIAL VEHICLE FOR PLANT PROTECTION
TECHNICAL FIELD [0001] The invention relates to the technical field of spraying machine, particularly to a spraying device for unmanned aerial vehicle for plant protection.
BACKGROUND OF THE INVENTION [0002] The unmanned aerial vehicle for plant protection are mainly used for spraying pesticide in forestry and agriculture. Comparing to the conventional spraying methods, the spraying efficiency of the unmanned aerial vehicle for plant protection is considerably higher. With the urbanization course proceeding, labor force in rural is increasingly running down, it is thus an inevitable trend in agriculture and forestry that mechanization works replace traditional artificial works in plant protection. In recent years, the modernizations of agriculture and forestry production get rapid development due to extensive use of the unmanned aerial vehicle.
[0003] The preventive treatment and disinfestation of crops pests generally rely on pesticides with high efficiency and low toxicity, resulting in importance of pesticide spraying. At present, spraying of the unmanned aerial vehicle for plant protection relies on sprayers arranged on the rack of the unmanned aerial vehicle. These sprayers spray pesticides in high altitude so that pesticides can be almost sprayed on the surface of crops’ leaves, rarely onto the back thereof, which extremely reduces the insecticidal effect. In the prior art, by providing a downwards electric push rod on each side of the body of the unmanned aerial vehicle, fixing sprayers between top ends of the two electronic push rods, connecting a controller with the electronic push rods which will synchronously extend and retract, the sprayers can extend into the crops and spray onto the back of the leaves of the crops. In this way, however, since the sprayers are fixed between the two electronic driving push rods, the installation
-22018100996 16 Jul 2018 requirement of the push rods is relatively higher. The push rods need to keep in sync during extension and retraction, otherwise it will cause a great punch on the sprayers in the fixed position to damage the sprayers easily. Furthermore, this method is only useful for the plant which is managed like a square but is not applicable to general vegetation, as the aerial vehicle for plant protection may fall down due to contact with plant’s branches. Besides, the spraying angle of the sprayer is inflexible according to this method.
SUMMARY OF THE INVENTION [0004] Based on the above, the object of the present invention is to overcome at least one problem of the prior arts and provide a spraying device for the unmanned aerial vehicle for plant protection which is easy to operate, with simple structure and durable life. The sprayer angle can be adjusted as the sprayer is mounted on the top end of the electronic drive push rod, so that the potion can be sprayed on the back of the crops.
[0005] Another object of the invention is to provide an unmanned aerial vehicle for plant protection including the spraying device.
[0006] In order to achieve the above-mentioned objects, the present invention provides a spraying device used for unmanned aerial vehicle for plant protection including at least one electric telescopic pole, a water pump module, and a controller, wherein a sprayer mounting base provided with a sprayer with adjustable sprayer angle is fixedly arranged on the top end of the electric telescopic pole, and the sprayer is connected with a water pipe connected to the water pump module. The electric telescopic pole and the water pump module are controlled by the controller.
[0007] The invention is simple in structure, technically reasonable, and easy to operate. While in use, the spraying device is mounted on the body of the unmanned aerial vehicle and the water pump module is connected to a medicine tank on the body
-32018100996 16 Jul 2018 of the unmanned aerial vehicle. When the unmanned aerial vehicle flies to the task area, a signal is sent to the controller. After processing the signal, the controller controls the extension and retraction of the electric telescopic pole to extend its top end into leaves of the crop branches. At the same time, the water pump module is in operation and the potion enters the sprayer through the water pipe, and the sprayer angle is adjusted towards the back of the leaves and thereby spraying potion onto the back of the crops through the sprayer. After spraying, the controller stops the water pump module and contracts the electric telescopic pole to the initial position. Since the sprayer is mounted on the top end of each electric telescopic pole, the extension and retraction of the electric telescopic pole will not influence the fixing of the sprayer, so that the device is durable with simple structure. In addition, the direction of the extension and retraction of the electric telescopic pole is considerably flexible. In this way, spraying onto the leaves surface of the crops by adjusting the sprayer angle can also be conducted.
[0008] Further, the sprayer mounting base is a steering engine and the sprayer is mounted on the rotating part of the steering engine. When changing the angle frequently, the steering engine can precisely turn the sprayer and adjust its angle.
[0009] In addition, the sprayer angle can also be adjusted by rotating the electric telescopic pole.
[0010] Further, the spraying device also includes a radar and a ranging module, both connected with the controller. When the unmanned aerial vehicle flies to the task area, the telescopic poles will extend automatically through the detection of radar without manual control and then the direction of the sprayer is adjusted by the precisely ranging module on the top end of the sprayer of the telescopic pole. When an obstacle is encountered, it firstly enters the detection range of the radar, then is detected by the ranging module. A two-dimensional coordinate is established. Through the analysis of the controller, the direction of the telescopic pole and the sprayer are self-adjusted. If
-42018100996 16 Jul 2018 the obstacle is above the sprayer, the telescopic pole will retract to keep the sprayer above the obstacle, which is suitable for complicated spraying tasks.
[0011] Further, the radar is a millimeter-wave radar. The millimeter-wave radar, with small size, low weight and high spatial resolution, has strong ability to penetrate fog, smoke, and dust. It can also work in all-weather and all-time with strong antiinterference ability.
[0012] Further, the length of the electric telescopic pole after extension is between 150cm and 200cm. The telescopic pole with excessive length will not only increase weight of the unmanned aerial vehicle for plant protection, but also cause inconvenience for operation and movement. However, the telescopic pole with insufficient length is unable to spray onto the back of the crops. Thus, the chosen range is easy to operate and satisfies the task need of the unmanned aerial vehicle. An electric telescopic pole with smaller weight and better flexibility is preferable.
[0013] Further, the electric telescopic pole includes an electric direct current motor and a telescopic pole. The electric telescopic pole supports a drive voltage of 12v, 24v, 36v, or 48v. The controller, to which the signal is emitted, processes the received PWM value wave and sends a corresponding signal to the electric direct current motor to execute a command for moving the telescopic pole, according to a predetermined instruction. When a bigger drive voltage is selected, the telescopic pole can extend and contract faster, that is, the sprayer can stretch out and draw back faster.
[0014] Further, the water pump module includes a water pump and an electronic speed control. The water pump is a direct current micro diaphragm water pump. The adopted direct current micro diaphragm water pump integrates advantages of a selfpriming pump and a chemical pump, which is corrosion resistant, self-primed, thermal protective, smooth to operate. It also can idle for a long time and work under load
-52018100996 16 Jul 2018 continuously. Furthermore, it has small size, low current, high pressure, and long service life.
[0015] Further, the sprayer is a pressure sprayer. When conducting plant protection using the pressure sprayer, spray-like spraying with wider spray range can be formed, allowing higher coverage rate on the surface of leaves of the crop branches, so that it has higher efficiency and hardly causes medicinal liquid waste. Because the sprayer is upward in using, the pressure sprayer head is preferable for the spraying of medicinal liquid.
[0016] Further, the water pipe is a plastic transparent water pipe. The remaining of the medicinal liquid in the water pipe can be observed through the plastic transparent water pipe when maintaining. At the same time, the soft plastic transparent water pipe can draw back and stretch out flexibly when the electric telescopic pole is extended and contracted and will not hinder the extension and contraction of the electric telescopic pole.
[0017] The invention also provides an unmanned aerial vehicle for plant protection including an aerial vehicle body and a spraying device according to the present invention. When the unmanned aerial vehicle for plant protection is in use, the telescopic pole can extend into the forest and spray medicinal liquid onto the back of the crops. The unmanned aerial vehicle is easy to operate and has a simple structure and the mounting angle of the electric telescopic pole can be adjusted flexibly.
[0018] Comparing with the prior art, desirable effects of the present invention can obtain. The invention is simply structured, technically reasonable, and easy to operate. While in use, the spraying device is mounted on the body of the unmanned aerial vehicle, the extension and contraction of the electric telescopic pole is controlled by the controller, the sprayer is faced to the back of the leaves via controlling the rotations of the telescopic pole and the steering engine after detection of the ranging module.
-62018100996 16 Jul 2018
At the same time, the water pump module is in operation, the potion enters the sprayer through the water pipe, thus the potion is sprayed on the back of the crops via the sprayer because the nozzle for sprayer can automatically face towards the back of the leaves of crops. When the obstacle is encountered, the medicinal liquid can be sprayed well on the plant through the rotations of the telescopic pole and the steering engine. After spraying, the water pump module stops and the electric telescopic pole contracts to the initial position via the controller. Since the sprayer is mounted on the top end of each electric telescopic pole, the extension and retraction of the electric telescopic poles will not influence the fixing of the sprayer, and the direction of the extension and retraction of the electric telescopic pole and the direction of spraying of the nozzle are flexible.
