Description

Technical Field

[0001] The invention relates to the field of rice planting, in particular to a fertilizing device for rice planting. Background Art

[0002] Rice is an annual herbaceous plant of the genus Oryza in the Poaceae family. It is one of the most important food crops in the world. It is not only a food, but also a link between the environment, economy and culture. Rice needs to absorb a variety of nutrients during its growth, such as nitrogen, phosphorus, potassium, etc. Rice is an effective way to supplement these nutrients to the soil. Through reasonable fertilization, the needs of rice at different growth stages can be met, providing strong guarantees for its normal growth and development.

[0003] Drone fertilization is an important technology in modern agriculture. It has the advantages of high efficiency, precision, and labor saving. It is especially suitable for large-scale rice cultivation. It has the advantages of high efficiency and time saving, precise and uniform, adaptable to complex terrain, reduced trampling losses and intelligent management. It can improve fertilizer utilization and reduce production costs. When using drone fertilization devices for fertilization, liquid fertilizers or powder fertilizers are generally used, and granular fertilizers cannot be applied. Because the particle size of granular fertilizers is relatively large, the drone nozzles are easily blocked, so drones cannot apply granular fertilizers. Granular fertilizers are relatively heavy, and manual fertilization with fertilizer buckets is very physically demanding, and the uniformity of manual fertilization cannot be guaranteed.

[0033] Example 3: Please refer to Figure 4 and Figure 8, this embodiment is further described for other embodiments. The prompt mechanism in the figure includes two installation boxes 27 that are symmetrically fixedly installed on the inner side of the storage box 3. A transmission rod 28 is rotatably installed on the inner side of the installation box 27. A second synchronous belt 29 is rotatably installed between the transmission rod 28 and the driving rod 15, so that the driving rod 15 can drive the transmission rod 28 to rotate synchronously through the second synchronous belt 29. Two symmetrically distributed sliding cavities are provided on the inner side of the installation box 27. A moving rod 30 is slidably installed between the two sliding cavities. The outer side of the moving rod 30 is aligned with the transmission rod 28. The outer side of each of the movable rods 30 is fixedly mounted with a second gear 31. When the second gear 31 on the movable rod 30 contacts the second gear 31 on the transmission rod 28, the transmission rod 28 can drive the movable rod 30 to rotate through the two second gears 31. The outer side of the movable rod 30 is fixedly mounted with a plurality of knocking rods 32 distributed symmetrically in the center. The inner side of the mounting box 27 is fixedly mounted with a spring plate 33. The movable rod 30 can drive the knocking rod 32 to rotate, so that the knocking rod 32 knocks the spring plate 33 to make a sound, which prompts the staff. The outer side of the movable rod 30 is rotatably mounted with a movable frame 34. The outer side of the mounting box 27 is provided with a slide groove for the limited sliding of the movable frame 34. Two symmetrically distributed material receiving plates 35 are slidably installed on the inner side of the storage box 3. One side of the material receiving plate 35 is fixedly connected to the outer side of the movable frame 34. A plurality of equally distributed insertion rods 36 are fixedly installed on the bottom of the material receiving plate 35. The insertion rod 36 slides through the storage box 3. A second spring 37 is fixedly installed between the bottom end of the insertion rod 36 and the outer side of the storage box 3. When granular fertilizer is loaded into the storage box 3, the material receiving plate 35 can be pressed to move downward so that the material receiving plate 35 passes through the insertion rod 36 compresses the second spring 37, and the receiving plate 35 can pull the movable frame 34 to move downward, so that the movable rod 30 is away from the transmission rod 28. When the granular fertilizer in the storage box 3 is reduced, the rebound force of the second spring 37 can be used to realize the upward movement of the movable rod 30, prompting the staff that the granular fertilizer has been applied, so that the staff can clearly know the stop position of fertilization. Both ends of the movable rod 30 are fixedly installed with convex rings, and the sliding cavity of the installation box 27 is provided with a positioning groove for the convex ring to limit the sliding of the convex ring, thereby improving the movement of the movable rod 30.

[0034] Working principle: First, the staff opens the sealed sliding door 38, and the sealed sliding door 38 drives the two arc-shaped baffles 39 to move along the inner side of the storage box 3, so that the arc-shaped baffles 39 block the gap between the sealed sliding door 38 and the storage box 3. Then, the staff puts the granular fertilizer into the storage box 3, and the granular fertilizer is accumulated on the two receiving plates 35. The weight of the granular fertilizer is used to make the receiving plates 35 pull the movable frame 34 downward and compress the second spring 37 so that the movable frame 34 drives the movable rod 30 away from the transmission rod 28. Subsequently, the staff operates the drone body 1 to take off, so that the drone body 1 moves above the rice field, and starts the drive motor 17. The drive motor 17 drives the drive rod 15 to rotate, so that the drive rod 15 can stir the storage box through the stirring rod 16. 3 is stirred, and at the same time, the driving rod 15 drives the rotating rod 14 to rotate through the first synchronous belt 18, so that the rotating rod 14 drives the receiving column 7 to rotate along the inner side of the discharge cylinder 5, and the multiple receiving frames 8 on the receiving column 7 are aligned with the bottom of the discharge box 4 in turn to catch the granular fertilizer discharged from the bottom of the storage box 3. At the same time, the rotating rod 14 drives the driven rod 19 to rotate through the two first gears 20, and the driven rod 19 drives the turntable 21 to rotate synchronously, so that the multiple pushing teeth 22 on the turntable 21 contact the hemispherical block 24 on the prismatic slide bar 23 in turn, and the pushing teeth 22 push the hemispherical block 24 to move, and the hemispherical block 24 drives the prismatic slide bar 23 to move horizontally and stretch the tension spring 25. The rebound force of the tension spring 25 is used to make the multiple pushing teeth 22 continuously push the hemispherical block 24 When the feeding column 7 is rotated, the feeding frame 8 is in a state of reciprocating shaking, and the granular fertilizer in the feeding frame 8 can be evenly distributed in the feeding frame 8. When the feeding frame 8 moves to the top of the discharge inclined plate 6, the granular fertilizer can be discharged downward along the discharge inclined plate 6, realizing anti-dumping. The agglomeration and anti-blocking effects are achieved, and the paddy field is dropped into the paddy field. As the rotating rod 14 rotates, continuous fertilization of the paddy field is achieved. As the granular fertilizer in the storage box 3 decreases, the rebound force of the second spring 37 is utilized to make the receiving plate 35 push the movable frame 34 to move upward, and the movable frame 34 drives the second gear 31 on the movable rod 30 to contact the second gear 31 on the transmission rod 28, and the knocking rod 32 on the movable rod 30 is close to the spring plate 33. Since the driving rod 15 drives the transmission rod 28 to rotate through the second synchronous belt 29, the transmission rod 28 drives the movable rod 30 to rotate through the two second gears 31, and the movable rod 30 drives the knocking rod 32 to knock the spring plate 33 to make a sound, prompting the staff that the granular fertilizer has been applied, so that the staff can clearly know.The fertilization stops at the position where the staff operates the drone body 1 to descend, replenish the material, and then fertilize the remaining area of the rice field, thereby completing the fertilization of the rice field, thereby improving the uniformity and convenience of granular fertilizer fertilization.
