Description

TECHNICAL FIELD

[0001] The application relates to the technical field of unmanned aerial vehicles, in particular to a pesticide spraying and irrigation integrated unmanned aerial vehicle facilitating pesticide mixing. BACKGROUND

[0002] With the development of agricultural modernization, unmanned aerial vehicles have been widely used in the fields of agricultural pesticide spraying and irrigation. By using unmanned aerial vehicles equipped with pesticide spraying and irrigation devices, the unmanned aerial vehicles can fly in complex terrains such as mountains and hills by means of satellite navigation systems such as GPS and Beidou combined with inertial navigation units, thus overcoming the difficulty of traditional agricultural machinery in reaching the places, expanding the operation range, and enabling the operators to control the take-off, landing and monitoring of the operation process on the ground. Compared with traditional manual spraying and irrigation, the operation speed of the unmanned aerial vehicle is greatly improved.

[0003] The pesticide spraying and irrigation device of the unmanned aerial vehicle comprises a liquid storage tank for storing pesticide, a delivery pump and a spraying device. The pesticide in the liquid storage tank is delivered to the spraying device by the delivery pump, and the spraying device is used for spraying and irrigating the agricultural field.

[0004] When mixing the pesticide, the required pesticide type, dosage and amount of adjuvant are determined according to the prevention and control requirements, and the required pesticide and adjuvant are poured into the aqueous solution for mixing. The mixed pesticide is poured into the liquid storage tank. In the prior art, when small-scale agricultural producers or small agricultural enterprises proportion the pesticide, adjuvant and aqueous solution, the workers control the amount of pesticide poured into the aqueous solution according to experience, which easily leads to inaccurate proportioning of the pesticide, thereby affecting the prevention and control effect of the agricultural spraying and irrigation. SUMMARY

[0005] Therefore, it is necessary to provide a pesticide spraying and irrigation integrated unmanned aerial vehicle facilitating pesticide mixing in order to solve the problem that the workers control the amount of pesticide poured into the aqueous solution according to experience, which easily leads to inaccurate proportioning of the pesticide, thereby affecting the prevention and control effect of the agricultural spraying and irrigation.

[0006] The unmanned aerial vehicle comprises a unmanned aerial vehicle body, a spraying mechanism mounted on the frame of the unmanned aerial vehicle body, and a liquid storage tank mounted on the inner side of the frame of the unmanned aerial vehicle body.

[0007] The mixing mechanism comprises two proportioning assemblies arranged on the two sides of the liquid storage tank and a mixing assembly arranged in the liquid storage tank.

[0008] The ratio assembly includes a medicament tank mounted on one side of the liquid storage tank and a transparent measuring cylinder, a drain pipe is communicated between the bottom end of the transparent measuring cylinder and the liquid storage tank, a piston is slidably connected to the inner wall of the transparent measuring cylinder, the top end of the piston is fixedly connected with a pull rod, the bottom end of the medicament tank is communicated with a liquid outlet pipe, the end of the liquid outlet pipe away from the medicament tank is connected with a three-way electromagnetic valve, the other two ends of the three-way electromagnetic valve are respectively connected with an air inlet pipe and a connecting pipe communicated with the transparent measuring cylinder, the inner wall of the drain pipe is rotatably connected with a mounting rod, the surface of the mounting rod is slidably connected with a cylinder, and the surface of the cylinder is fixedly connected with two scraping rods.

[0009] In one of the embodiments, the ratio assembly further comprises two fixed rods fixedly connected to the surface of the mounting rod, the bottom end of the fixed rod is fixedly connected with a sponge, the surface of the sponge is attached to the inner bottom wall of the transparent measuring cylinder, the inner bottom wall of the transparent measuring cylinder is provided with two grooves, and the inner bottom wall of the transparent measuring cylinder is fixedly connected with a pressing rod arranged between the two grooves.

[0010] In one of the embodiments, the mixing assembly comprises a rotating rod rotatably connected to the inner wall of the liquid storage tank, fans are mounted at both ends of the liquid storage tank, one end of the rotating shaft of each fan is fixedly connected with both ends of the rotating rod, three dials are fixedly connected to the surface of the rotating rod, a water wheel is rotatably connected to one side of the dial, and a through groove is formed in the surface of the dial. The medicament in the liquid storage tank can be stirred, and the water wheel can rotate and self-rotate under the action of the through groove, so that the mixing effect of the medicament in the liquid storage tank is ensured, and the unmanned aerial vehicle body drives the mixing assembly to operate by wind power during the flight of the unmanned aerial vehicle, so that the mixing is realized without power.

[0011] In one of the embodiments, the surface of the drain pipe is provided with a fixed frame, the inner wall of the fixed frame is slidably connected with a rack, the surface of the rack is meshingly connected with a gear, the top end of the rotating shaft of the gear is fixedly connected with the bottom end of the mounting rod, the top end of the rack is slidably connected with a sliding block, the top end of the sliding block is fixedly connected with the inner top wall of the fixed frame, and a second spring is fixedly connected between one side of the sliding block and the inner wall of the rack. The mounting rod and the cylinder drive the corresponding fixed rod, sponge and scraping rod to rotate synchronously.

[0012] In one of the embodiments, one end of the rack penetrates the fixed frame, and an included angle is formed between one end of the rack and the vertical surface, a connecting rod is fixedly connected to the surface of the top end of the pull rod, and an inclined plate is fixedly connected to the bottom end of the connecting rod. When the piston moves downward, the inclined plate drives the rack to drive the gear to rotate synchronously, so that the consistency of the device during operation is ensured.

[0013] In one of the embodiments, the vertical section of the mounting rod is a "cross" shape, and the top end of the fixing rod is fixedly connected with the inner top wall of the cylinder and is provided with a first spring. This is conducive to the synchronous rotation of the cylinder when the mounting rod rotates.

[0014] In one of the embodiments, the surface of the fan rotating shaft is fixedly connected with a one-way bearing, and the outer edge of the one-way bearing is fixedly connected with the inner wall of the liquid storage tank.

[0015] In one of the embodiments, the surface of the connecting pipe and the surface of the liquid discharge pipe are provided with one-way valves. This avoids the entry of the medicament and gas in the transparent cylinder into the connecting pipe during use, and also avoids the reverse flow of the liquid in the liquid storage tank into the liquid discharge pipe.

[0016] In one of the embodiments, the surface of the liquid discharge pipe is inclined, the inner wall of the liquid discharge pipe is fixedly connected with a sealing bearing, and the inner edge of the sealing bearing is fixedly connected with the surface of the gear rotating shaft.

[0017] In one of the embodiments, the vertical section of the scraping rod is an isosceles triangle. This is conducive to the downward flow of the medicament scraped by the scraping rod.

[0018] 1. In the present scheme, through the interaction of the medicament tank, the transparent cylinder, the piston, and the pull rod in the proportioning assembly, it is conducive to achieving the quantitative taking of the required medicament dosage according to the proportioning requirements. When the piston pushes the required metered medicament into the liquid storage tank, it will simultaneously drive the fixed rod, the sponge, and the scraping rod to rotate synchronously, so that the scraping rod will scrape the medicament at the bottom end of the piston, the sponge will adsorb the liquid medicament or solid medicament remaining on the inner bottom wall of the transparent cylinder, and the medicament adsorbed by the sponge will be squeezed out by the squeezing rod during the rotation of the sponge. This ensures the adsorption effect of the sponge and the full discharge of the medicament in the transparent cylinder. At the same time, under the action of the air inlet pipe, it is conducive to the upward movement of the piston to form a negative pressure to adsorb the gas, and the downward movement of the piston is conducive to pushing the medicament remaining in the liquid discharge pipe into the liquid storage tank, so that the medicament in the transparent cylinder completely enters the liquid storage tank to mix with the aqueous solution, ensuring the accuracy of the proportioning, thereby ensuring the prevention and control effect of agricultural spraying irrigation.

[0019] 2. The setting of the mixing assembly, driven by the rotating rod, the plurality of dials, and the water wheel, is conducive to stirring the liquid in the liquid storage tank, and under the action of the through slot, the water wheel can rotate while self-rotating, ensuring the mixing effect of the liquid in the liquid storage tank. Moreover, the unmanned aerial vehicle body drives the mixing assembly to operate by wind power during the flight of the pesticide, realizing non-powered stirring and energy saving and environmental protection.

[0038] The present application is described below in conjunction with Figures 1-10 The present application describes a pesticide irrigation integrated unmanned aerial vehicle for easy adjustment of pesticide mixing.

[0039] As Figures 1-10 shown, in one embodiment, a pesticide irrigation integrated unmanned aerial vehicle for easy adjustment of pesticide mixing, comprising: an unmanned aerial vehicle body 100, a rack of the unmanned aerial vehicle body 100 is provided with a spraying mechanism 200, and an inner side of the rack of the unmanned aerial vehicle body 100 is provided with a liquid storage tank 300;

[0040] A mixing mechanism 400, the mixing mechanism 400 comprises two proportioning assemblies 410 respectively arranged on both sides of the liquid storage tank 300 and a mixing assembly 420 arranged inside the liquid storage tank 300;

[0041] The proportioning assembly 410 comprises a pesticide tank 411 and a transparent graduated cylinder 412 arranged on one side of the liquid storage tank 300, a liquid discharge pipe 416 is in communication between the bottom end of the transparent graduated cylinder 412 and the liquid storage tank 300, a piston 413 is slidably connected to the inner wall of the transparent graduated cylinder 412, a pull rod 414 is fixedly connected to the top end of the piston 413, a liquid outlet pipe 4111 is in communication with the bottom end of the pesticide tank 411, one end of the liquid outlet pipe 4111 away from the pesticide tank 411 is connected with a three-way electromagnetic valve 415, the other two ends of the three-way electromagnetic valve 415 are respectively connected with an air inlet pipe 4151 and a connecting pipe 4152 in communication with the transparent graduated cylinder 412, an installation rod 417 is rotatably connected to the inner wall of the liquid discharge pipe 416, a cylinder 4171 is slidably connected to the surface upper end of the installation rod 417, and two scraper rods 4172 are fixedly connected to the surface of the cylinder 4171.

[0042] In the embodiment, the spraying mechanism 200 comprises a water pump, a pipeline and a plurality of spray heads. The water inlet end of the water pump is in communication with the liquid storage tank 300. The pipeline connects the water outlet end of the water pump and the spray heads. When the spraying mechanism 200 performs the spraying operation, the water pump is started by the controller, and the liquid in the liquid storage tank 300 is sent to the plurality of spray heads through the pipeline, and is sprayed from the plurality of spray heads to realize the pesticide spraying operation. In the scheme, the water solution in the liquid can realize irrigation of the agricultural products to a certain extent when the liquid is sprayed on the agricultural products.

[0043] The two proportioning assemblies 410 are centrally symmetrical with respect to the liquid storage tank 300. The center point of the liquid storage tank 300 and the center point of the unmanned aerial vehicle body 100 are located on the same axis.

[0044] The top end of the liquid storage tank 300 and the top end of the pesticide tank 411 are provided with liquid inlets, and sealing covers are installed on the liquid inlets in a matched mode. When the liquid is proportioned, the quantitative water solution is added into the liquid storage tank 300 through the liquid inlets, and the liquid pesticide required to be added is directly poured into the pesticide tank 411. Part of the powder pesticide is added with a small amount of water solution for on-site proportioning, and is poured into the pesticide tank 411 after the proportioning. The sealing covers block the liquid inlets in the use process of the device.

[0045] The surface of the piston 413 is attached to the inner wall of the transparent measuring cylinder 412. The surface of the transparent measuring cylinder 412 is provided with scale lines. The connection part of the connecting pipe 4152 and the transparent measuring cylinder 412 is located below the piston 413. The flow states of the liquid outlet pipe 4111, the air inlet pipe 4151 and the connecting pipe 4152 are controlled by the three-way electromagnetic valve 415 in the use process of the device. When the pesticide in the pesticide tank 411 needs to be introduced into the transparent measuring cylinder 412, the three-way electromagnetic valve 415 is used to make the liquid outlet pipe 4111 communicate with the connecting pipe 4152, and the end connected with the air inlet pipe 4151 is closed. When the liquid introduction of the pesticide is completed, the three-way electromagnetic valve 415 is used to make the air inlet pipe 4151 communicate with the connecting pipe 4152, and the end connected with the liquid outlet pipe 4111 is closed.

[0046] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , the proportioning assembly 410 further comprises two fixed rods 4173 fixedly connected to the surface of the mounting rod 417. The bottom end of the fixed rod 4173 is fixedly connected with a sponge 4174. The surface of the sponge 4174 is attached to the inner bottom wall of the transparent measuring cylinder 412. The inner bottom wall of the transparent measuring cylinder 412 is provided with two grooves 4121. The inner bottom wall of the transparent measuring cylinder 412 is fixedly connected with a pressing rod 4122. The pressing rod 4122 is arranged between the two grooves 4121.

[0047] In this embodiment, the bottom of the transparent cylinder 412 is conical, the inclination angle of the fixed rod 4173 and the inclination angle of the sponge 4174 are the same as the inclination angle of the inner bottom wall of the transparent cylinder 412, and the overall shape of the extrusion rod 4122 is half a cylinder. When the fixed rod 4173 drives the sponge 4174 in the rotating path, the sponge 4174 coincides with the extrusion rod 4122, the bottom end of the fixed rod 4173 does not contact the surface upper end of the extrusion rod 4122, and there is a certain distance between the bottom end of the fixed rod 4173 and the surface upper end of the extrusion rod 4122.

[0048] As shown in Figure 2 , Figure 9 and Figure 10 , the mixing assembly 420 includes a rotating rod 421 rotatably connected to the inner wall of the liquid storage tank 300, and fans 422 are installed at both ends of the liquid storage tank 300. One end of the rotating shaft of each fan 422 is fixedly connected to one end of the rotating rod 421. The surface of the rotating rod 421 is fixedly connected to three number of push plates 423. One side of each push plate 423 is rotatably connected to a water wheel 424. The surface of each push plate 423 is provided with a through slot 425.

[0049] In this embodiment, the surface of the push plate 423 is curved into an arc shape. When the rotating rod 421 rotates, it drives the plurality of push plates 423 to rotate clockwise. Referring to Figure 9 , because the center of rotation of the water wheel 424 and the center of the through slot 425 are eccentric, when the push plate 423 rotates and the aqueous solution passes through the through slot 425, the aqueous solution has a certain flow rate and kinetic energy, which drives the water wheel 424 to rotate under the action of the aqueous solution flow,

[0050] One end of the rotating shaft of the fan 422 away from the rotating rod 421 penetrates through the protective frame of the fan 422. When the medicament and the aqueous solution in the liquid storage tank 300 need to be mixed during the process of dispensing the medicinal liquid, the staff can manually rotate the rotating shaft of the fan 422 to drive the rotating rod 421 to rotate, thereby driving the plurality of push plates 423 to rotate. The push plate 423 rotates while driving the plurality of water wheels 424 to rotate synchronously. The water wheel 424 rotates synchronously under the action of the through slot 425 and the water flow to mix the medicinal liquid in the liquid storage tank 300.

[0051] When the unmanned aerial vehicle body 100 sprays the medicinal liquid during flight, the fan 422 is driven to rotate under the action of the wind, thereby driving the rotating rod 421 to rotate synchronously, realizing power-free stirring.

[0052] As shown in Figure 4 and Figure 7As shown, the surface of the liquid drainage pipe 416 is provided with a fixed frame 418, the inner wall of the fixed frame 418 is slidably connected with a rack 4181, the surface of the rack 4181 is meshedly connected with a gear 4182, the top end of the rotating shaft of the gear 4182 is fixedly connected with the bottom end of the mounting rod 417, the top end of the rack 4181 is slidably connected with a sliding block 4183, the top end of the sliding block 4183 is fixedly connected with the inner top wall of the fixed frame 418, and the second spring 4184 is fixedly connected between the inner wall of the rack 4181 and one side of the sliding block 4183. One end of the rack 4181 penetrates out of the fixed frame 418, and an included angle is formed between one end of the rack 4181 and the vertical surface. The surface of the pull rod 414 is fixedly connected with a connecting rod 4141 at the upper end, and the connecting rod 4141 is fixedly connected with an inclined plate 4142 at the bottom end.

[0053] In this embodiment, the inclination angle of the inclined plate 4142 is the same as that of one end of the rack 4181. When the device is in the initial state, the pull rod 414 drives the inclined plate 4142 to be located at the lowest position through the connecting rod 4141. At this time, the rack 4181 is pressed to move to the farthest distance in the direction of the fixed frame 418, and the second spring 4184 is in the compressed state. When the connecting rod 4141 drives the inclined plate 4142 to move upward, the rack 4181 and the second spring 4184 lose the pressing, at this time, the second spring 4184 resets and drives the rack 4181 to move away from the fixed frame 418.

[0054] The top end of the rack 4181 is provided with a sliding groove matched with the sliding block 4183, and the second spring 4184 is arranged in the sliding groove. When the rack 4181 moves away from the fixed frame 418, the sliding groove and the sliding block 4183 limit the movement distance of the rack 4181, so that the inclined plate 4142 contacts one end of the rack 4181 during the downward movement.

[0055] As shown in the figure, Figure 8 The vertical section of the mounting rod 417 is a "cross" shape, and the first spring 4175 is fixedly connected between the top end of the fixed rod 4173 and the inner top wall of the cylinder 4171.

[0056] In this embodiment, the inner wall of the cylinder 4171 is provided with a sliding groove matched with the mounting rod 417, so that when the mounting rod 417 rotates, the cylinder 4171 rotates synchronously.

[0057] When the device is in the initial state, the piston 413 is located at the lowest position. At this time, the bottom end of the piston 413 abuts against the top end of the cylinder 4171 and the top end of the scraping rod 4172, and the first spring 4175 is in the compressed state. When the piston 413 moves upward, the piston 413 releases the pressing of the cylinder 4171 and the first spring 4175, at this time, the first spring 4175 resets and drives the cylinder 4171 to move upward.

[0058] As shown in Figure 10 The surface of the rotating shaft of the fan 422 is fixedly connected with a one-way bearing, and the outer edge of the one-way bearing is fixedly connected with the inner wall of the liquid storage tank 300.

[0059] In this embodiment, the inner edge of the one-way bearing is fixedly connected with the surface of the rotating shaft of the fan 422, so that the two fans 422 can only rotate in one direction, and when the two fans 422 rotate in one direction, they can only drive the rotating rod 421 to rotate clockwise. See Figure 9 .

[0060] As shown in Figure 4 The surface of the connecting pipe 4152 and the surface of the liquid discharge pipe 416 are provided with one-way valves.

[0061] In this embodiment, the one-way valve on the surface of the connecting pipe 4152 makes the connecting pipe 4152 a one-way connecting pipe 4152, so that the medicament and external gas can only enter the transparent measuring cylinder 412 in one direction, and the liquid and gas in the transparent measuring cylinder 412 cannot pass through the connecting pipe 4152;

[0062] The one-way valve on the surface of the liquid discharge pipe 416 makes the liquid discharge pipe 416 a one-way liquid discharge pipe 416, so that only the medicament in the transparent measuring cylinder 412 can enter the liquid storage tank 300 through the liquid discharge pipe 416, and the liquid in the liquid storage tank 300 cannot enter the liquid discharge pipe 416.

[0063] As shown in Figure 7 The surface of the liquid discharge pipe 416 is inclined, the inner wall of the liquid discharge pipe 416 is fixedly connected with a sealing bearing, and the inner edge of the sealing bearing is fixedly connected with the surface of the rotating shaft of the gear 4182.

[0064] In this embodiment, the sealing bearing ensures the sealing between the rotating shaft of the gear 4182 and the liquid discharge pipe 416 when the gear 4182 rotates.

[0065] As shown in Figure 8 The vertical section of the scraping rod 4172 is an isosceles triangle.

[0066] In this embodiment, the scraping rod 4172 forms an included angle between the two sides and the vertical plane, and in the initial state of the device, the top end of the horizontal plane of the scraping rod 4172 is in contact with the bottom end of the piston 413.

[0067] Working principle: when the sprayed liquid needs to be mixed, a certain amount of aqueous solution is poured into the liquid storage tank 300, and the used medicament is poured into the medicament tank 411, at this time, under the action of the three-way electromagnetic valve 415, the outlet pipe 4111 is in communication with the connecting pipe 4152, the staff pulls the rod 414 to drive the piston 413 to slowly move upward to form negative pressure adsorption, the medicament in the medicament tank 411 will enter the transparent measuring cylinder 412 through the outlet pipe 4111 and the connecting pipe 4152, when the bottom end of the piston 413 is flush with the scale line of the required medicament, the medicament in the transparent measuring cylinder 412 is the required amount of medicament, at this time, the staff pushes the piston 413 downward by the rod 414 and extrudes the medicament in the transparent measuring cylinder 412 to enter the liquid storage tank 300 through the drain pipe 416 to mix with the aqueous solution, and when the piston 413 moves downward to a certain height, the inclined plate 4142 contacts one end of the rack 4181, and the bottom end of the piston 413 contacts the top end of the cylinder 4171 and the top end of the scraper 4172, at this time, the piston 413 continues to move downward, under the action of the inclined plate 4142, the rack 4181, the gear 4182, the mounting rod 417 and the cylinder 4171, the scraper 4172, the fixed rod 4173 and the sponge 4174 will rotate synchronously, in the rotating process, the scraper 4172 will scrape the medicament at the bottom end of the piston 413, the sponge 4174 will scrape the medicament on the inner wall of the transparent measuring cylinder 412, and when the sponge 4174 coincides with the extrusion rod 4122 in the rotating process, the sponge 4174 will be extruded under the interaction of the fixed rod 4173 and the extrusion rod 4122, and the extruded medicament will flow into the groove 4121 and enter the drain pipe 416 through the groove 4121, when the piston 413 cannot continue to move downward, the three-way electromagnetic valve 415 makes the air inlet pipe 4151 in communication with the connecting pipe 4152, at this time, the piston 413 is pulled upward again by the rod 414, the external air will enter the transparent measuring cylinder 412 through the air inlet pipe 4151 and the connecting pipe 4152, when the piston 413 moves upward to a certain height, the piston 413 is pushed downward again, in the process of moving downward, the piston 413 extrudes the gas in the transparent measuring cylinder 412 to generate gas pressure in the drain pipe 416 and push the medicament remaining in the drain pipe 416 into the liquid storage tank 300, so that the medicament in the transparent measuring cylinder 412 completely enters the liquid storage tank 300 to mix with the aqueous solution.

[0068] It should be noted that the water pump, three-way electromagnetic valve and the like in the above description are relatively mature devices in the prior art, and the specific model can be selected according to actual needs, and the power supply of the water pump and the three-way electromagnetic valve can be the built-in power supply, and the specific power supply mode is selected as the case may be, which will not be described here.
