Description

Technical Field

[0001] This invention relates to the field of agricultural implements technology, and in particular to a farmland nutrient application device. Background Technology

[0002] In modern agricultural production systems, the rational and precise application of fertilizers plays a crucial role in increasing crop yields and improving their quality. Traditional fertilization methods mostly rely on manual operation using hand-held spreaders. This method is not only extremely labor-intensive, but also prone to uneven fertilizer distribution due to variations in the operator's physical condition and skill level, thus affecting crop growth consistency and ultimately yield and quality. Furthermore, traditional manual fertilization methods are relatively inefficient and cannot meet the demands of today's large-scale agricultural production for efficient and precise operations.

[0003] With the continuous advancement of science and technology, various automated fertilization equipment has emerged, aiming to overcome the problems existing in traditional fertilization methods. For example, some fertilizer spreading devices using the principle of fan feeding already exist on the market. These devices have improved the efficiency of fertilization operations to a certain extent and effectively reduced the demand for labor. However, these existing automated fertilization devices still have significant limitations. First, they usually still require operators to hold the spreading pipe by hand, which not only increases the operator's workload but also limits the speed and coverage area of ​​fertilization. Second, due to wind interference, the distribution of fertilizer is often difficult to achieve an ideal uniformity, especially under conditions of high wind speed or complex terrain. This uneven distribution will be more pronounced, and crop growth will also be adversely affected by uneven fertilization. Summary of the Invention

[0010] Furthermore, a fixing post is provided on the storage hopper, and a tension spring is provided on the fixing post. One end of the tension spring is connected to the fixing post, and the other end is connected to the guide block of the shielding ring.

[0011] Furthermore, the second support plate is also provided with a worm gear and a worm, which are located inside the rotating disk. The worm is connected to the third motor. A rotating sleeve is also provided inside the worm gear. The rotating sleeve has two arc-shaped grooves. A lifting platform is also provided inside the rotating sleeve. Both sides of the lifting platform are provided with protrusions. The two protrusions are respectively embedded in the two arc-shaped grooves. The lifting platform rises or falls as the worm gear rotates.

[0012] Furthermore, a baffle is provided at the bottom of the blade, the baffle is located below the partition, the baffle is movably connected to the lifting platform, and the baffle moves closer to or further away from the through hole on the partition as the lifting platform moves.

[0013] Furthermore, a protective cover is provided between the first support plate and the second support plate. The protective cover is fitted over the outside of the storage hopper.

[0039] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0040] A farmland nutrient application device includes a mounting plate 1, a shoulder strap 11 on the mounting plate 1, a storage bin 2 on the side of the mounting plate 1 facing away from the shoulder strap 11, a partition 21 inside the storage bin 2, a rotating disk 22 below the partition 21, a paddle 23 connected to the rotating disk 22 above the partition 21, a first motor 24 for driving the rotating disk 22 and the paddle 23 at the bottom of the storage bin 2, multiple fan blades 221 on the side wall of the rotating disk 22, multiple through holes 211 through the partition 21, and a discharge chute 25 corresponding to the position of the rotating disk 22 on the side wall of the storage bin 2.

[0041] Furthermore, the mounting plate 1 is provided with a first support plate 12 and a second support plate 13, and the storage bucket 2 is movably installed between the first support plate 12 and the second support plate 13, with the first support plate 12 located above the second support plate 13.

[0042] Furthermore, a second motor 121 is provided on the first support plate 12, a rack is wound around the storage bin 2, and a gear 122 that meshes with the rack is provided on the second motor 121. The second motor 121 drives the storage bin 2 to rotate between the first support plate 12 and the second support plate 13.

[0043] Furthermore, a shielding ring 3 is fitted onto the storage hopper 2. The shielding ring 3 is located at the position of the discharge chute 25. The shielding ring 3 is provided with a first opening 31 and a second opening 32. The first opening 31 is located above the second opening 32 and the size of the first opening 31 is the same as that of the discharge chute 25. There are two second openings 32, which are symmetrically arranged on both sides of the shielding ring 3. The size of the second opening 32 is smaller than that of the discharge chute 25. The shielding ring 3 is also provided with a movable groove 33. The storage hopper 2 is provided with a positioning block 26, which is embedded in the movable groove 33.

[0044] Furthermore, a guide platform 131 is fixedly installed on the second support plate 13. A groove is provided on the guide platform 131. A guide block 34 is provided on the shielding ring 3. When the shielding ring 3 rotates with the storage tank 2, the guide block 34 moves along the guide platform 131 and enters or exits the groove, so that the shielding ring 3 can move up and down on the storage tank 2.

[0045] Furthermore, a fixing post 27 is provided on the storage bin 2, and a tension spring 271 is provided on the fixing post 27. One end of the tension spring 271 is connected to the fixing post 27, and the other end is connected to the guide block 34 of the shielding ring 3.

[0046] In a specific embodiment, such as Figures 1 to 8As shown, the farmland nutrient application device proposed in this application is mainly used for fertilizing farmland. It includes a vertically mounted mounting plate 1 with two shoulder straps 11 for easy carrying by the operator. A sponge pad is also provided on the side of the mounting plate 1 facing the shoulder straps 11 to improve comfort during carrying. A first support plate 12 and a second support plate 13 are located on the side of the mounting plate 1 facing away from the shoulder straps 11, with the first support plate 12 positioned above the second support plate 13. A storage tank 2 is movably mounted between the first and second support plates 12 and 13. A partition 21 is provided inside the storage tank 2, fixedly mounted on its inner wall. A rotating disk 22 is located below the partition 21, also inside the storage tank 2. A first motor 24, connected to the rotating disk 22, is located at the bottom of the storage tank 2 and fixedly mounted on the bottom of the second support plate 13. A blade 23 is also installed on the rotating disk 22, located above the partition 21. When the first motor 24 drives the rotating disk 22 to rotate, the blade 23 above the partition 21 also rotates. Multiple fan blades 221 are also provided on the side wall of the rotating disk 22. Multiple through holes 211 are provided on the partition 21, and a discharge chute 25 is provided on the storage tank 2. The discharge chute 25 is located at the same horizontal height as the rotating disk 22. Since the rotating disk 22 is located inside the storage tank 2, the discharge chute 25 serves as a channel connecting the rotating disk 22 to the external environment. Fertilizer in the storage tank 2 can reach the rotating disk 22 through the through holes 211 on the partition 21. When the rotating disk 22 rotates, the fan blades 221 also rotate. Figure 5 As shown, the upper surface of the rotating disk 22 is designed to be concave towards the center, which allows the fertilizer to be concentrated on the rotating disk 22 and fall between the adjacent fan blades 221. With the help of the centrifugal force generated when the rotating disk 22 and fan blades 221 rotate, the fertilizer can be evenly spread from the discharge trough 25 to the outside.

[0047] The storage hopper 2 is rotatably mounted between the first support plate 12 and the second support plate 13. A second motor 121 is mounted on the first support plate 12. A rack is also arranged around the side wall of the storage hopper 2. A gear 122 meshes with the rack on the second motor 121. When the second motor 121 drives the gear 122 to rotate, it drives the rack to rotate, thereby rotating the storage hopper 2. A shielding ring 3 is also fitted onto the storage hopper 2 at the position of the discharge chute 25. Two positioning blocks 26 are set on the storage hopper 2. These two positioning blocks 26 are respectively embedded in the movable grooves 33 on both sides of the shielding ring 3. The shielding ring 3 rotates with the storage hopper 2. Through this design, the shielding ring 3 can slide up and down in the storage hopper 2 along the setting direction of the movable grooves 33. The shielding ring 3 has a first opening 31 and a second opening 32. The first opening 31 is located above the second opening 32, and the size of the first opening 31 is the same as the size of the discharge chute 25. There are two second openings 32, symmetrically arranged on both sides of the shielding ring 3. The size of the second opening 32 is smaller than the size of the discharge chute 25. A guide platform 131 is also provided on the second support plate 13. The guide platform 131 is circular, and the storage tank 2 is located inside the guide platform 131. Two grooves are symmetrically arranged on the guide platform 131. Guide blocks 34 are provided on both sides of the outer wall of the shielding ring 3. These two guide blocks 34 abut against the upper surface of the guide platform 131. When the shielding ring 3 rotates with the storage tank 2, the guide blocks 34 move along the guide platform 131 and enter or exit the grooves. When the guide block 34 enters the groove on the guide platform 131, the shielding ring 3 moves downward on the storage tank 2, aligning the first opening 31 on the shielding ring 3 with the discharge chute 25. When the guide block 34 exits the groove on the guide platform 131, the shielding ring 3 moves upward on the storage tank 2, aligning the second opening 32 on the shielding ring 3 with the discharge chute 25. Furthermore, two fixed posts 27 are provided on the side wall of the storage tank 2, located below the two guide blocks 34 respectively. A tension spring 271 is provided between each fixed post 27 and the guide block 34 above it. The tension spring 271 ensures that when the guide block 34 moves to the groove position, it can move to the bottom of the groove under the action of the spring 271's rebound force, thereby ensuring the stability and reliability of the shielding ring 3 during the rising and falling motion.

[0048] In practical use, the operator first pours fertilizer into the storage tank 2, then carries the mounting plate 1 on their back. The fertilizer passes through the through-holes 211 on the partition 21 inside the storage tank 2 to the rotating disk 22. The paddles 23 above the partition 21 act as a stirrer during rotation, ensuring that the fertilizer does not clog. The rotating disk 22 is equipped with multiple fan blades 221. When the rotating disk 22 is started, the fan blades 221 rotate accordingly, using centrifugal force to evenly distribute the fertilizer on the rotating disk 22 onto the surrounding farmland through the discharge chute 25. The operator only needs to walk to achieve large-area fertilization of the farmland. In addition, the rotation speed of the rotating disk 22 can be adjusted by controlling the first motor 24, thereby further controlling the fertilization area. Specifically, the faster the rotation speed of the rotating disk 22, the larger the fertilizer coverage area. The second motor 121 drives the storage bin 2 to rotate, causing the shielding ring 3 to rise and fall on the storage bin 2. When the first opening 31 on the shielding ring 3 is at the same height as the discharge chute 25, the discharge chute 25 is unshielded, and the fertilization area of ​​the farmland is fan-shaped. When the operator walks in the farmland, they can fertilize a large area along the path they pass, thus achieving uniform fertilization over a large area. When the second opening 32 on the shielding ring 3 is at the same height as the discharge chute 25, the middle section of the discharge chute 25 is blocked by the shielding ring 3, and the fertilizer can only be scattered outward from the two second openings 32 on both sides of the shielding ring 3. In this way, the fertilization area is on both sides of the storage bin 2. When the operator needs to fertilize the farmland on both sides of the road at the same time, this design can effectively reduce the waste of fertilizer in non-planting areas such as the middle road. By adjusting the relative positions of the shielding ring 3 and the discharge chute 25, this application can be adjusted and adapted according to different farmland conditions and fertilization needs, flexibly choosing to fertilize on a large scale or fertilize farmland on both sides of the road.

[0049] Furthermore, the second support plate 13 is also provided with a worm gear 132 and a worm 133, which are located inside the rotating disk 22. The worm 133 is connected to the third motor. A rotating sleeve 134 is also provided inside the worm gear 132. The rotating sleeve 134 is provided with two arc-shaped grooves. A lifting platform 135 is also provided inside the rotating sleeve 134. Both sides of the lifting platform 135 are provided with protrusions, which are respectively embedded in the two arc-shaped grooves. The lifting platform 135 rises or falls as the worm gear 132 rotates.

[0050] Furthermore, a baffle 231 is provided at the bottom of the blade 23. The baffle 231 is located below the partition 21 and is movably connected to the lifting platform 135. The baffle 231 moves closer to or further away from the through hole 211 on the partition 21 as the lifting platform 135 moves.

[0051] In a specific embodiment, such as Figures 9 to 10As shown, a worm gear 132 and a worm 133 are also installed on the second support plate 13. The worm gear 132 and the worm 133 are located inside the rotating disk 22. The worm 133 meshes with the worm gear 132. A third motor is used to drive the worm 133 to rotate. When the worm 133 rotates, the worm gear 132 rotates accordingly. A rotating sleeve 134 is provided inside the worm gear 132. The rotating sleeve 134 rotates together with the worm gear 132. A lifting platform 135 is also provided inside the rotating sleeve 134. Protrusions are provided on both sides of the lifting platform 135. Two arc-shaped grooves are provided on the side wall of the rotating sleeve 134. The two protrusions on both sides of the lifting platform 135 are respectively embedded in the two arc-shaped grooves of the rotating sleeve. When the rotating sleeve 134 rotates with the worm gear 132, the interior of the rotating sleeve 134 of the lifting platform 135 rises or falls through the cooperation of the protrusions and the arc-shaped grooves. Furthermore, a baffle 231 is installed at the bottom of the blade 23, located below the partition 21. The bottom of the baffle 231 is rotatably connected to the top of the lifting platform 135. When the blade 23 rotates, the lifting platform 135 does not rotate with the blade 23, ensuring that the rotation of the blade 23 does not interfere with the lifting platform 135. When the lifting platform 135 rises, the baffle 231 rises accordingly and approaches the through hole 211 on the partition 21. The proximity of the baffle 231 to the through hole 211 hinders the speed at which fertilizer in the storage tank 2 enters the rotating disk 22 through the through hole 211. By adjusting the distance between the baffle 231 and the through hole 211 on the partition 21, the amount of fertilizer flowing into the rotating disk 22 through the through hole 211 can be controlled. This mechanism allows operators to flexibly adjust the amount of fertilizer applied according to the actual needs of the farmland and the fertilizer application standards, thereby reducing fertilizer waste and improving fertilization efficiency.

[0052] Furthermore, a protective cover 14 is provided between the first support plate 12 and the second support plate 13. The protective cover 14 is fitted over the outside of the storage hopper 2. A moisture-proof plate 4 is provided on the protective cover 14. The moisture-proof plate 4 is movably mounted on the protective cover 14 via a connecting rod 41. A spring 42 is provided on the connecting rod 41. One end of the spring 42 is connected to the moisture-proof plate 4, and the other end of the spring 42 is connected to the protective cover 14. The moisture-proof plate 4 can move closer to or further away from the protective cover 14 along the connecting rod 41, and the discharge chute 25 is exposed or blocked by the moisture-proof plate 4 accordingly.

[0053] Furthermore, the bottom of the second support plate 13 is provided with a support leg 15, which is movably connected to the second support plate 13 via a rotating shaft. A support rod 43 connected to the moisture-proof board 4 is movably provided on the second support plate 13. The end of the support leg 15 away from the rotating shaft rotates with the rotating shaft and abuts or separates from the support rod 43.

[0054] In a specific embodiment, such as Figures 11 to 13As shown, a protective cover 14 is provided between the first support plate 12 and the second support plate 13. The storage tank 2 is located inside the protective cover 14. A moisture-proof plate 4 is provided at the end of the protective cover 14 near the discharge chute 25. The moisture-proof plate 4 is movably mounted on the protective cover 14 via a connecting rod 41. A spring 42 is provided on the connecting rod 41. One end of the spring 42 is connected to the moisture-proof plate 4, and the other end of the spring 42 is connected to the protective cover 14. The moisture-proof plate 4 can move closer to or away from the protective cover 14 along the connecting rod 41, thereby blocking or exposing the discharge chute 25. Two support legs 15 are provided at the bottom of the second support plate 13. The support legs 15 are movably connected to the second support plate 13 via a rotating shaft. When the end of the support leg 15 away from the rotating shaft rotates with the rotating shaft, it abuts against or separates from the support rod 43 at the bottom of the moisture-proof plate 4. In practical use, when the operator needs to rest, the agricultural nutrient application equipment proposed in this application can be stably placed on the ground through the cooperation of the support legs 15 and the mounting plate 1. At this time, the moisture-proof plate 4 blocks the discharge chute 25. The moisture-proof plate 4 is equipped with a sealing strip to prevent the fertilizer inside the storage tank 2 from getting damp when fertilization is not being carried out. After the operator has finished resting, the mounting plate 1 is carried on the back using the shoulder strap 11, and the support legs 15 are folded up. When the support legs 15 are in the folded state, the end away from the rotation axis abuts against the support rod 43, pushing the support rod 43 upward, causing the moisture-proof plate 4 to rise accordingly. At this time, the moisture-proof plate 4 does not block the discharge chute 25, and the fertilizer in the storage tank 2 can be discharged from the discharge chute 25.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
