Description

Technical Field

[0001] The invention relates to the technical field of agricultural implements, in particular to a farmland nutrient application device. Background Art

[0002] In the modern agricultural production system, the reasonable and precise application of fertilizers plays a vital role in increasing crop yields and improving their quality. Traditional fertilization methods mostly rely on manual handheld feeding tubes, which is not only extremely labor-intensive, but also difficult to ensure the uniformity of fertilizer spreading due to differences in the physical condition and technical level of the operators, which in turn affects the consistency of crop growth and the final yield and quality. In addition, the efficiency of traditional manual fertilization methods is relatively low, and it is difficult to meet the current large-scale agricultural production needs for efficient and precise operations.

[0003] With the continuous advancement of science and technology, various types of automated fertilization equipment have emerged to overcome the various problems existing in traditional fertilization methods. For example, there are already some fertilizer spreading devices on the market that use the principle of fan feeding. 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 equipment still have obvious limitations. First of all, they usually still require operators to hold the spreading tube to operate, which not only increases the labor burden of the operator, but also limits the speed and coverage area of ​​fertilization. Secondly, due to the interference of wind factors, the distribution of fertilizers is often difficult to achieve an ideal uniform state, especially when the wind speed is high or the terrain conditions are more complex, the unevenness of this distribution will be more significant, and due to the uneven fertilization, the growth of crops will also be adversely affected.

[0042] Furthermore, a shielding ring 3 is also provided on the storage barrel 2, and the shielding ring 3 is located at the position where the discharge trough 25 is located. A first opening 31 and a second opening 32 are provided on the shielding ring 3, and the first opening 31 is located above the second opening 32, and the first opening 31 is consistent with the size of the discharge trough 25. There are two second openings 32 and they are symmetrically arranged on both sides of the shielding ring 3, and the size of the second opening 32 is smaller than the size of the discharge trough 25. A movable groove 33 is also provided on the shielding ring 3, and a positioning block 26 is provided on the storage barrel 2, and the positioning block 26 is embedded in the movable groove 33.

[0043] Furthermore, a guide platform 131 is fixedly provided on the second support plate 13, a groove is provided on the guide platform 131, and a guide block 34 is provided on the shielding ring 3.

[0044] Furthermore, a fixing column 27 is provided on the material storage barrel 2 , and a tension spring 271 is provided on the fixing column 27 . One end of the tension spring 271 is connected to the fixing column 27 , and the other end is connected to the guide block 34 of the shielding ring 3 .

[0045] In a specific embodiment, Figures 1 to 8As shown, a farmland nutrient application equipment proposed in the present application is mainly used for fertilizing farmland. It includes a vertically arranged mounting plate 1, on which two shoulder straps 11 are arranged, so that the operator can carry the mounting plate 1, and a sponge pad is also arranged on the side of the mounting plate 1 facing the shoulder straps 11, which can improve the comfort during the carrying process. A first support plate 12 and a second support plate 13 are arranged on the side of the mounting plate 1 facing away from the shoulder straps 11, and the first support plate 12 is located above the second support plate 13, and the storage barrel 2 is movably installed between the first support plate 12 and the second support plate 13. A partition plate 21 is arranged inside the storage barrel 2, and the partition plate 21 is fixedly mounted on the inner wall of the storage barrel 2. A rotating disk 22 is arranged below the partition plate 21, and the rotating disk 22 is also located inside the storage barrel 2. A first motor 24 connected to the rotating disk 22 is arranged at the bottom of the storage barrel 2, and the first motor 24 is fixedly mounted at the bottom of the second support plate 13. A paddle 23 is also installed on the rotating disk 22. The paddle 23 is located above the partition 21. When the first motor 24 drives the rotating disk 22 to rotate, the paddle 23 above the partition 21 also rotates accordingly. In addition, a plurality of blades 221 are provided on the side wall of the rotating disk 22, a plurality of through holes 211 are provided on the partition 21, and a discharge chute 25 is provided on the storage barrel 2. The discharge chute 25 is provided at the same horizontal height as the rotating disk 22. Since the rotating disk 22 is located inside the storage barrel 2, the discharge chute 25 serves as a channel connecting the rotating disk 22 with the external environment. The fertilizer in the storage barrel 2 can reach the rotating disk 22 through the through holes 211 on the partition 21, and when the rotating disk 22 rotates, the blades 221 also rotate accordingly. And as Figure 5 As shown, the upper surface of the rotating disk 22 is designed to be concave toward the center, so that the fertilizer can be concentrated on the rotating disk 22, and the fertilizer falls between adjacent fan blades 221. With the help of the centrifugal force generated by the rotation of the rotating disk 22 and the fan blades 221, the fertilizer can be evenly spread from the discharge trough 25 to the outside.

[0046] Among them, the storage barrel 2 is rotatably installed between the first support plate 12 and the second support plate 13, and the second motor 121 is installed on the first support plate 12. A circle of racks is also set around the side wall of the storage barrel 2. The second motor 121 is provided with a gear 122 meshing with the rack. When the second motor 121 drives the gear 122 to rotate, it drives the rack to rotate, thereby rotating the storage barrel 2. A shielding ring 3 is also set on the position of the storage barrel 2 at the discharge trough 25, and two positioning blocks 26 are set on the storage barrel 2. These two positioning blocks 26 are respectively embedded in the movable grooves 33 on both sides of the shielding ring 3, and the shielding ring 3 will rotate with the storage barrel 2. Through this design, the shielding ring 3 can slide up and down on the storage barrel 2 along the setting direction of the movable groove 33. A first opening 31 and a second opening 32 are set on the shielding ring 3, and the first opening 31 is located above the second opening 32, and the size of the first opening 31 is consistent with the size of the discharge trough 25. There are two second openings 32, which are symmetrically arranged on both sides of the shielding ring 3, and the size of the second opening 32 is smaller than the size of the discharge trough 25. A guide platform 131 is also arranged on the second support plate 13. The guide platform 131 is annular, and the storage barrel 2 is located inside the guide platform 131. Two grooves are symmetrically arranged on the guide platform 131. Guide blocks 34 are arranged 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 barrel 2, the guide blocks 34 will move along the guide platform 131 and enter or exit the groove. When the guide block 34 enters the groove on the guide platform 131, the shielding ring 3 moves downward on the storage barrel 2, so that the first opening 31 on the shielding ring 3 is aligned with the discharge trough 25. When the guide block 34 exits the groove on the guide platform 131, the shielding ring 3 moves upward on the storage barrel 2, so that the second opening 32 on the shielding ring 3 is aligned with the discharge trough 25. In addition, two fixed columns 27 are provided on the side wall of the storage barrel 2, which are respectively located below the two guide blocks 34. A tension spring 271 is provided between each fixed column 27 and the guide block 34 above it. The setting of the tension spring 271 ensures that when the guide block 34 moves to the groove position, the guide block 34 can be moved to the bottom of the groove under the action of the rebound force of the tension spring 271, thereby ensuring the stability and reliability of the shielding ring 3 during the rising and falling movement process.

[0047] In actual use, the operator first pours the fertilizer into the storage barrel 2, and then carries the mounting plate 1. The fertilizer reaches the rotating disk 22 via the through hole 211 on the partition 21 in the storage barrel 2. The blades 23 above the partition 21 play a stirring role during the rotation process, which can ensure that the fertilizer will not be blocked. The rotating disk 22 is equipped with a plurality of blades 221. When the rotating disk 22 is started, the blades 221 rotate accordingly, and the fertilizer on the rotating disk 22 is evenly distributed to the farmland outside through the discharge trough 25 by centrifugal force. The operator only needs to move on foot to achieve large-scale fertilization operations on the farmland. In addition, the rotation speed of the rotating disk 22 can be adjusted by controlling the first motor 24, so as to further control the area range of fertilization. Specifically, the faster the rotation speed of the rotating disk 22, the larger the coverage area of ​​the fertilizer. The shielding ring 3 can be raised and lowered on the storage barrel 2 by driving the storage barrel 2 to rotate through the second motor 121. When the first opening 31 on the shielding ring 3 is at the same height as the discharge trough 25, the discharge trough 25 is in an unblocked state. At this time, the fertilization area for the farmland is a fan-shaped area. When the operator walks in the farmland, a large range of fertilizers can be applied to the path passed by, thereby uniformly fertilizing the farmland over a large area. When the second opening 32 on the shielding ring 3 is at the same height as the discharge trough 25, the middle section of the discharge trough 25 is blocked by the shielding ring 3, and the fertilizer can only be sprinkled out 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 barrel 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 position of the shielding ring 3 and the discharge chute 25, the present application can be adjusted and adapted according to different farmland conditions and fertilization requirements, and flexibly select large-scale fertilization or fertilization for farmland on both sides of the road.

[0048] Furthermore, a worm wheel 132 and a worm 133 are also provided on the second support plate 13. The worm wheel 132 and the worm 133 are located in the rotating disk 22, and the worm 133 is connected to the third motor. A rotating sleeve 134 is also provided in the worm wheel 132. Two arc grooves are provided on the rotating sleeve 134. A lifting platform 135 is also provided in the rotating sleeve 134. Both sides of the lifting platform 135 are provided with protrusions. The two protrusions are respectively embedded in the two arc grooves. The lifting platform 135 rises or falls as the worm wheel 132 rotates.

[0049] Furthermore, a baffle 231 is provided at the bottom of the blade 23 , and the baffle 231 is located below the partition 21 . The baffle 231 is movably connected to the lifting platform 135 , and the baffle 231 moves closer to or away from the through hole 211 on the partition 21 as the lifting platform 135 moves.

[0050] In a specific embodiment, Figures 9 and 10As shown, a worm wheel 132 and a worm 133 are also installed on the second support plate 13. The worm wheel 132 and the worm 133 are located in the rotating disk 22. The worm 133 and the worm wheel 132 are meshed with each other. The third motor is used to drive the worm 133 to rotate. When the worm 133 rotates, the worm wheel 132 rotates accordingly. A rotating sleeve 134 is arranged in the worm wheel 132. The rotating sleeve 134 rotates with the worm wheel 132. A lifting platform 135 is also arranged in the rotating sleeve 134. The lifting platform 135 is provided with protrusions on both sides. The side wall of the rotating sleeve 134 is provided with two arc grooves. The two protrusions on both sides of the lifting platform 135 are respectively embedded in the two arc grooves of the rotating sleeve. When the rotating sleeve 134 rotates with the worm wheel 132, the rotating sleeve 134 of the lifting platform 135 is raised or lowered by the cooperation of the protrusions and the arc grooves. A baffle 231 is provided at the bottom of the paddle 23. The baffle 231 is located below the partition 21. The bottom of the baffle 231 is rotatably connected to the top of the lifting platform 135. When the paddle 23 rotates, the lifting platform 135 will not rotate with the paddle 23, so that the rotation of the paddle 23 will 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 baffle 231 approaching the through hole 211 will hinder the speed at which the fertilizer in the storage barrel 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 from the through hole 211 into the rotating disk 22 can be controlled. This mechanism enables the operator to flexibly adjust the amount of fertilizer applied according to the actual needs of the farmland and the fertilizer application standards, thereby achieving the purpose of reducing fertilizer waste and improving fertilization efficiency.

[0051] Furthermore, a protective cover 14 is provided between the first support plate 12 and the second support plate 13. The protective cover 14 is sleeved on the outside of the storage barrel 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 through 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 along the connecting rod 41 towards or away from the protective cover 14, and the discharge trough 25 is exposed or blocked by the moisture-proof plate 4.

[0052] Furthermore, a support foot 15 is provided at the bottom of the second support plate 13, and the support foot 15 is movably connected to the second support plate 13 through a rotating shaft. A support rod 43 connected to the moisture-proof plate 4 is movably provided on the second support plate 13, and the end of the support foot 15 away from the rotating shaft rotates with the rotating shaft and abuts against or separates from the support rod 43.

Two legs 15 are provided at the bottom of the second support plate 13, the legs 15 are movably connected to the second support plate 13 through a rotating shaft, and when the end of the legs 15 away from the rotating shaft rotates with the rotating shaft, they abut or separate from the support rod 43 at the bottom of the moisture-proof plate 4. In actual use, when the operator needs to take a break, the support legs 15 and the mounting plate 1 can be used to place the farmland nutrient application equipment proposed in this application firmly on the ground. At this time, the moisture-proof plate 4 blocks the discharge trough 25. The moisture-proof plate 4 is provided with a sealing strip to prevent the fertilizer inside the storage barrel 2 from getting wet when the fertilization work is not being performed. After the operator has finished taking a break, the mounting plate 1 is carried on the shoulder strap 11, and the support legs 15 are stored. The end of the support legs 15 away from the rotating shaft is in contact with the support rod 43 in the stored state, and the support rod 43 is lifted upward, so that the moisture-proof plate 4 rises accordingly. At this time, the moisture-proof plate 4 does not block the discharge trough 25, and the fertilizer in the storage barrel 2 can be sprinkled out from the discharge trough 25.
