Description

Technical Field

[0001] The invention relates to the field of unmanned aerial vehicles, and in particular to a unmanned aerial vehicle with a granular fertilizer spreading function. Background Art

[0002] At present, the main methods of field seeding are manual seeding and mechanical seeding. Manual seeding is inefficient and labor-intensive, while mechanical seeding is easily affected by terrain, making it impossible for the machine to operate normally, and it is easy to damage the land and seeds during the seeding process. Therefore, aerial seeding is used because of its high efficiency, low cost and the advantages of not being restricted by terrain.

[0003] Existing drone spraying generally uses a medicine pot to directly pour the material or uses a centrifugal device to rotate and throw the particles out of the device. This method is not suitable for drugs with large particles or very light particles. For example, microcapsule suspensions are characterized by the fact that the drug is composed of very small microcapsules, which are then made into drug particles. The characteristics of such drugs are large volume and small weight. Destroying the drug particles during spraying will affect the efficacy. Through gravity leakage, the medicine will be stuck in the drop port and cannot go down. When using centrifugal spraying, the drug microcapsules will be destroyed. Summary of the invention

At the lower end inside the perforated roller, a stirring rod is rotatably arranged, and a plurality of stirring blocks are fixedly arranged on the outer wall of the stirring rod. On the inner wall of the loading shell at the upper end of the perforated roller, a baffle is fixedly arranged. At the upper end of the baffle on the inner wall of the loading shell, a feeding tray is fixedly arranged.

[0013] Beneficial effects The present invention provides a drone with a function of spreading granular fertilizer. It has the following beneficial effects: 1. The present invention provides a drone with the function of granular fertilizer spreading. By installing a loading shell at the lower end of the airframe, a cavity for placing fertilizer is arranged inside the loading shell, and a rotating mechanism is arranged inside the loading shell. During the driving process, the rotating mechanism continuously stirs and disperses the fertilizer and assists in scraping the inner wall, which can effectively avoid the blockage of fertilizer at the feeding port and the adhesion of a small amount of moist fertilizer to the inner wall, and the feeding is more thorough. At the same time, after the rotating mechanism completes the auxiliary dialing and feeding, the fertilizer falls on the 30° inclined semi-circular inclined plate and converges at the angle between the semi-circular inclined plate and the perforated drum. The continuously rotating perforated drum causes the granular fertilizer to fall along the holes on the perforated drum to complete the spreading effect of the granular fertilizer. When larger granular fertilizers are stuck in the holes, since there are continuously rotating dialing rods and dialing blocks arranged inside the perforated drum, the dialing blocks continuously squeeze the granular fertilizers stuck in the holes of the perforated drum during rotation, enabling them to complete the feeding function, thus effectively avoiding the blockage problem during the spreading process of the granular fertilizer.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment: As Figures 1-6 shown, an embodiment of the present invention provides a drone with a function of spreading granular fertilizer, which includes a fuselage 1 and a loading shell 3. The loading shell 3 is fixedly installed on the lower end face of the fuselage 1. Outer shells 4 are fixedly arranged on both sides of the outer wall of the loading shell 3. A top plate 14 is embedded in the upper end face of the loading shell 3. A rotating mechanism 13 for stirring and dispersing fertilizer is installed at the midpoint of the upper end face of the top plate 14. Four wings 2 are equidistantly arranged around the outer wall of the fuselage 1. A feeding head 5 penetrates through the upper end of the front end face of the outer wall of the loading shell 3. A feeding port 15 is opened on the upper end face of the feeding head 5; Specifically, by installing the loading shell 3 at the lower end of the fuselage 1, it rises into the air together with the fuselage 1. The loading shell 3 is provided with a feeding head 5, which can quickly load the required granular fertilizer to be spread into the loading shell 3, and then complete the lifting and carrying for use.

[0018] Referring to Figures 3-4 , the rotating mechanism 13 includes a first motor 1302. The first motor 1302 is fixedly connected to the top plate 14. A rotating column 1304 is fixedly arranged at the output end of the first motor 1302. On both sides of the outer wall of the rotating column 1304 near one end of the first motor 1302, a first connecting rod 1301 and a second connecting rod 1303 are respectively fixedly arranged. At the ends of the lower end faces of the first connecting rod 1301 and the second connecting rod 1303 far from the rotating column 1304, a first vertical rod 1305 and a second vertical rod 1307 are respectively fixedly arranged. An auxiliary block 1306 is fixedly arranged on the lower end face of the first vertical rod 1305. A spiral blade 1308 is fixedly sleeved on the outer wall of the end of the rotating column 1304 far from the first motor 1302; the spiral blade 1308 is located inside the blanking port 16. The outer wall of the side of the first vertical rod 1305 far from the first connecting rod 1301 is movably attached to the inner wall of the loading shell 3; Specifically, during use, the first motor 1302 starts to drive the rotating column 1304 at the output end to rotate. After the rotating column 1304 rotates, it drives the spiral blade 1308 on the outside to rotate synchronously. Since the spiral blade 1308 is located inside the blanking port 16, it can stir the granular fertilizer accumulated inside the blanking port 16, thereby preventing blockage. At the same time, when the rotating column 1304 rotates, it will drive the first connecting rod 1301 and the second connecting rod 1303 on the outside to rotate synchronously. Subsequently, the first vertical rod 1305, the second vertical rod 1307, and the auxiliary block 1306 located at the lower end of the first vertical rod 1305 move together. During the movement of the second vertical rod 1307, it continuously contacts the inner wall of the loading shell 3 to complete the internal scraping effect. The auxiliary block 1306 is also located at the blanking port 16 and outside the spiral blade 1308, so as to achieve an auxiliary pushing effect.

[0019] Refer to Figures 5-6 , on one inner wall of the lower end of the loading shell 3, a semi-circular inclined plate 6 is fixedly arranged. A perforated drum 7 is rotatably sleeved on one side of the lower end of the loading shell 3 away from the semi-circular inclined plate 6. A stirring rod 12 is rotatably arranged at the lower end inside the perforated drum 7, and a plurality of stirring blocks 11 are fixedly arranged on the outer wall of the stirring rod 12. A baffle 8 is fixedly arranged on the inner wall of the loading shell 3 at the upper end of the perforated drum 7. A blanking plate 17 is fixedly arranged on the inner wall of the loading shell 3 at the upper end of the baffle 8; the upper end surface of the blanking plate 17 is concave downward, and a blanking port 16 is penetrated and opened at one side edge of the lower end surface of the blanking plate 17. The semi-circular inclined plate 6 is located directly below the blanking port 16 and is inclined at 30°; the lowest end of the semi-circular inclined plate 6 is located at the midpoint position of one side of the perforated drum 7. An outlet 9 is opened at the midpoint of the bottom end surface of the loading shell 3, and the perforated drum 7 is located above the outlet 9; Specifically, due to the downward concave structure of the blanking plate 17, when the granular fertilizer falls on the blanking plate 17, it will concentrate and flow downward. Since the lowest point of the depression of the blanking plate 17 is at the blanking port 16, the granular fertilizer is concentrated at the position of the blanking port 16 and then is assisted by the rotating mechanism 13 to be stirred and dispersed; when the granular fertilizer falls, it will gather at the included angle position between the semi-circular inclined plate 6 and the perforated drum 7, and then the granular fertilizer completes the falling and spreading through the holes 10 on the perforated drum 7.

[0020] Refer to Figures 5-6 , a plurality of holes 10 are opened on the outer wall of the perforated drum 7. A second motor and a third motor are respectively fixedly arranged inside the two outer shells 4. One end of the perforated drum 7 is fixedly connected to the output end of the second motor, and one end of the stirring rod 12 is fixedly connected to the output end of the third motor. The plurality of stirring blocks 11 are grouped in threes and divided into multiple groups. The number of groups of the multiple groups of stirring blocks 11 is the same as the number of holes 10 in the single-row horizontal direction of the multiple holes 10. In each group of stirring blocks 11, the three stirring blocks 11 are arranged in an equidistant circular pattern around the stirring rod 12; Specifically, the second motor drives the perforated drum 7 to rotate. During the rotation of the perforated drum 7, it continuously drives the granular fertilizer accumulated between the semi-circular inclined plate 6 and the perforated drum 7 through the holes 10, prompting the granular fertilizer to fall into the discharge port 9 to complete the sowing of the granular fertilizer; while the third motor drives the stirring rod 12 to rotate. During the rotation of the stirring rod 12, the outer stirring block 11 is driven to rotate together. During the rotation of the stirring block 11, it continuously approaches the hole 10. When a granular fertilizer with a larger particle diameter is stuck in the hole 10 of the perforated drum 7, the continuously rotating stirring block 11 squeezes and pushes the granular fertilizer stuck in the hole 10, thereby completing the dredging of the hole 10 and avoiding the blockage during the feeding process of the granular fertilizer.

[0021] Working principle: When the drone is in use, first load the granular fertilizer inside the loading shell 3 and fixedly connect it to the lower end of the fuselage 1. Subsequently, the fuselage 1 uses the four wings 2 to take off and transport. When fertilization is required, start the first motor 1302 at the upper end to drive the rotating column 1304 at the output end to rotate. After the rotating column 1304 rotates, it drives the outer spiral blade 1308 to rotate synchronously. When the rotating column 1304 rotates, it drives the first vertical rod 1305, the second vertical rod 1307, and the auxiliary block 1306 located at the lower end of the first vertical rod 1305 to move together. During the movement of the second vertical rod 1307, it continuously contacts the inner wall of the loading shell 3 to complete the internal scraping effect, while the spiral blade 1308 and the auxiliary block 1306 are located at the feeding port 16 to stir and disperse the materials at the feeding port 16. Subsequently, the granular fertilizer falls and accumulates at the included angle position between the semi-circular inclined plate 6 and the perforated drum 7. At this time, the second motor and the third motor are started to drive the perforated drum 7 and the stirring rod 12 to move respectively. During the rotation of the perforated drum 7, it continuously drives the granular fertilizer accumulated between the semi-circular inclined plate 6 and the perforated drum 7 through the holes 10; while during the rotation of the stirring rod 12, the outer stirring block 11 is driven to rotate together. During the rotation of the stirring block 11, it continuously approaches the hole 10. When a granular fertilizer with a larger particle diameter is stuck in the hole 10 of the perforated drum 7, the continuously rotating stirring block 11 squeezes and pushes the granular fertilizer stuck in the hole 10, thereby completing the dredging of the hole 10. Finally, the granular fertilizer is sprayed out from the discharge port 9 to complete the sowing.
