Description

Technical Field

[0001] This invention relates to the field of wheat fertilization technology, specifically a multi-functional fertilization device for wheat fields. Background Technology

[0002] Deep fertilization, where fertilizer is released into the soil at a certain depth during topdressing, reduces fertilizer volatilization and surface runoff, improves nutrient utilization, and induces wheat roots to grow deeper, enhancing the plant's resistance to lodging and drought. It also reduces nutrient loss; for example, shallow application of nitrogen fertilizer (such as urea) can result in a 10%-30% loss due to ammonia volatilization, while deep burial can reduce volatilization loss to less than 5%. It also avoids nutrient loss due to rainwater runoff, making it particularly suitable for rainy areas. However, due to the large land area and varying ground hardness, the equipment needs frequent adjustments to maintain the fertilization depth within the preset range. On hard ground, the equipment may suspend itself, leading to failed deep fertilization. Fertilizer volatilization requires applying pressure to the equipment. On softer ground, the equipment can easily penetrate the soil, requiring simultaneous compaction by the compaction device. To avoid frequent equipment adjustments during fertilization, a device that can quickly adapt to different ground conditions is needed.

[0003] Chinese Patent CN117084011B discloses an agricultural wheat planting and fertilization device, including a tiller. A soil ripper is fixedly installed on the lower side of the tiller, and a mounting plate is fixedly connected to the right end face of the tiller. A limit plate is fixedly connected to the right end face of the soil ripper. The limit plate contains a pressure mechanism for creating pits in the soil. The pressure mechanism also contains a fertilization mechanism for applying fertilizer to the created pits. A tamping mechanism for compacting the fertilizer-filled pits is located on the right side of the mounting plate. The pressure mechanism includes a left eccentric wheel. The fertilization mechanism comprises an arc-shaped rod, a pressure block, and a push block. The pressure mechanism controls the fertilization state of the fertilization mechanism through the push block. A movable wheel is rotatably connected to the middle of the mounting plate, and a driven shaft is rotatably connected to the left side of the mounting plate. A left driven sprocket is fixedly connected to the rear side of the driven shaft. A transmission sprocket is fixedly connected to the middle of the movable wheel. The transmission sprocket is connected to the left driven sprocket via a chain. A connecting plate is rotatably connected to the front side of the mounting plate at the right end of the tiller. The front end of the driven shaft is rotatably connected to the connecting plate, and the front end face of the connecting plate is fixedly connected to the rear end face of the left eccentric wheel.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot quickly adjust the pressure applied to the equipment during operation, cannot adapt to different ground surfaces for fertilization, and cannot assist in evenly spreading the material to avoid fertilizer being squeezed out at the bottom of the hopper.

[0006] Based on this, the present invention designs a multifunctional fertilization device for wheat fields to solve the above problems. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-functional fertilization device for wheat fields.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0014] Furthermore, the uniform feeding mechanism includes a reciprocating sweeping component and a second driving component, wherein the reciprocating sweeping component is mounted on the frame and the second driving component is mounted on one side of the frame.

[0015] Furthermore, the reciprocating sweeping assembly includes: a material box, a reciprocating screw, a second guide rod, a connecting seat, an L-shaped plate, and a cleaning rod.

The L-shaped plate is slidably connected to the second guide rod. One side of the connecting seat is fixedly connected to the L-shaped plate. The cleaning rod is fixedly installed on the L-shaped plate. The end of the cleaning rod away from the L-shaped plate is located inside the material box. The bottom of the material box is V-shaped, and multiple fertilizer dischargers are fixedly installed at the bottom of the material box.

[0016] Furthermore, the second drive assembly includes: a driven rubber guide wheel, an electric push cylinder, an auxiliary rubber guide wheel, and a driving rubber guide wheel. The driven rubber guide wheel is fixedly connected to one end of the reciprocating screw, the electric push cylinder is fixedly mounted on the frame, the auxiliary rubber guide wheel is rotatably connected to the output end of the electric push cylinder via a rotating shaft, and the driving rubber guide wheel is rotatably connected to the frame via a rotating shaft.

[0017] Furthermore, the trenching and backfilling mechanism includes a trenching component and a backfilling component. Multiple trenching components are installed on the front side of the frame, and multiple backfilling components are installed on the middle side of the frame. The trenching components and backfilling components correspond one-to-one.

[0018] Furthermore, the trenching assembly includes: vertical rods, arc blades, and a feeding pipe. Multiple vertical rods are fixedly installed on the frame, and each vertical rod is rotatably connected to two arc blades via a rotating shaft. The distance between the rear sides of the two arc blades is greater than the distance between their front sides. One end of the feeding pipe is fixedly installed on the vertical rod, with the end of the feeding pipe closest to the vertical rod located behind the two arc blades. The end of the feeding pipe furthest from the vertical rod is fixedly connected to the output end of the fertilizer applicator.

[0019] Furthermore, the backfill assembly includes: a support frame, a compaction wheel, a support rod, and a second spring. One end of the support frame is rotatably connected to the middle side of the machine frame via a rotating shaft. The compaction wheel is rotatably connected to the end of the support frame away from the machine frame via a rotating shaft.

The second spring is sleeved on the support rod. One end of the second spring is tightly attached to the support frame, and the other end of the second spring is tightly attached to the machine frame.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, rollers roll on the ground, primarily supporting the frame with minimal pressure. As the amount of fertilizer in the uniform feeding mechanism decreases, and the overall weight of the fertilizing equipment lightens, the output of the drive motor of the first drive component rotates, causing the transmission rod to rotate by a preset angle. This rotation of the transmission rod drives the three-quarter cam, half cam, and quarter cam to rotate simultaneously. The three-quarter cam rotates 45 degrees, lifting one side of the outermost rotating frame, causing it to rotate by the preset angle and raising the rollers. At this point, the entire frame is subjected to pressure from the two rollers, allowing the equipment to continue fertilizing within a preset depth. When the amount of fertilizer further decreases, and the overall weight of the fertilizing equipment lightens again, the drive motor... The output end rotates, causing the transmission rod to rotate at a preset angle. The three-quarter cam, half cam, and quarter cam rotate simultaneously. After the three-quarter cam rotates forty-five degrees, the outermost rotating frame remains suspended. The rotating frame corresponding to the half cam rotates. After rotating to the preset angle, the rollers rise. At this time, the entire frame is subjected to the pressure of the four rollers. As it continues to rotate, the protruding end of the quarter cam contacts the rotating frame and lifts it up. At this time, the entire frame is subjected to the pressure of the six rollers. This is beneficial for quickly adjusting the pressure applied to the equipment during operation, avoiding insufficient trenching depth or backfilling failure due to the trenching and backfilling mechanism being suspended, which would result in fertilizer waste. At the same time, it allows the equipment to adapt to different ground hardness levels for fertilization.

[0022] 2. The power of the compaction wheel of the trenching and backfilling mechanism is transmitted to the fertilizer discharger and reciprocating sweeping component of the uniform conveying mechanism through a linkage transmission mechanism. The extension of the output end of the electric actuator drives the auxiliary rubber guide wheel to move upward. One side of the auxiliary rubber guide wheel is in contact with the driven rubber guide wheel, and the other side is in contact with the driving rubber guide wheel. The rotation of the auxiliary rubber guide wheel drives the rotation of the driven rubber guide wheel, which in turn drives the rotation of the reciprocating screw. The rotation drives the connecting seat to move left and right, which in turn drives the L-shaped plate to move left and right, which in turn drives the cleaning rod to move left and right. The fertilizer in the auxiliary material box is spread evenly inside the box. The second guide rod assists the L-shaped plate in moving left and right, preventing the L-shaped plate from rotating during the movement. When the fertilizer in the box is almost empty, the cleaning rod moves left and right to sweep the fertilizer into the fertilizer discharger, preventing fertilizer from remaining in the box. The fertilizer discharger evenly discharges the fertilizer into the trenching and backfilling mechanism, which helps to evenly spread the fertilizer and prevents fertilizer from being squeezed and left at the bottom of the box.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The present invention will be further described below with reference to embodiments.

[0039] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0040] Example 1: In some examples, please refer to Figures 1-11A multifunctional fertilization device for wheat fields includes a frame 1, and further includes: a ditching and backfilling mechanism 2, a uniform conveying mechanism 3, a pressure regulating mechanism 4, and a linkage transmission mechanism 5. The ditching and backfilling mechanism 2 for ditching, fertilizing, backfilling, and compacting the wheat field is installed on the front side of the frame 1. The uniform conveying mechanism 3 for uniformly conveying fertilizer is installed on the upper side of the frame 1. The pressure regulating mechanism 4 for applying adjustable downward pressure to the frame 1 is installed on the rear side of the frame 1. The linkage transmission mechanism 5 for transmitting power between the ditching and backfilling mechanism 2 and the uniform conveying mechanism 3 is installed on the ditching and backfilling mechanism 2.

[0041] The pressure regulating mechanism 4 includes a pressure applying component and a multi-adjustment component. A pressure applying component that applies downward pressure to the frame 1 is installed on the rear side of the frame 1, and a multi-adjustment component that performs multiple adjustments on the downward pressure applied by the pressure applying component is installed on the rear side of the frame 1.

[0042] like Figure 2 , Figure 3 , Figure 6 , Figure 10 As shown, the pressure application assembly includes: a sliding frame 41, a rotating frame 42, a first guide rod 43, a C-shaped plate 44, a first spring 45, and a roller 46. Multiple threaded rods 47 are fixedly installed on the frame 1. The sliding frame 41 is slidably connected to the threaded rods 47. A nut is tightened onto the end of the threaded rod 47 away from the frame 1 to firmly fix the sliding frame 41 to the frame 1. Multiple rotating frames 42 are evenly distributed on the sliding frame 41. The rotating frames 42 are rotatably connected to the sliding frame 41 via a rotating shaft. Multiple first springs 45... One end of the guide rod 43 is slidably connected to the side of the rotating frame 42 away from the sliding frame 41. A limit piece 48 is fixedly installed on the end of the first guide rod 43 near the rotating frame 42. The C-shaped plate 44 is fixedly installed on the side of the first guide rod 43 away from the rotating frame 42. The first spring 45 is sleeved on the first guide rod 43. One end of the first spring 45 is in close contact with the rotating frame 42, and the other end of the first spring 45 is in close contact with the C-shaped plate 44. The roller 46 is rotatably connected to the side of the C-shaped plate 44 away from the first guide rod 43 via a rotating shaft.

[0043] The fertilization equipment moves under the traction of external machinery. The roller 46 of the pressure application component of the pressure regulating mechanism 4 is in contact with the ground and rolls on the ground. At this time, the roller 46 supports the frame 1. The roller 46 moves up and down, causing the C-shaped plate 44 to move up and down. The C-shaped plate 44 moves up and down, causing the first guide rod 43 to move up and down in the rotating frame 42. The first spring 45 undergoes elastic deformation. The roller 46 rolls on the ground and moves up and down at the same time. The limiting piece 48 prevents the first guide rod 43 from slipping out of the rotating frame 42. At this time, the roller 46 mainly supports the support and exerts less pressure on the support.

[0044] When the soil is soft and the pressure regulating mechanism 4 is not needed, the sliding frame 41 can be removed from the threaded rod 47 to remove the pressure regulating mechanism 4.

[0045] The multi-adjustment assembly includes a first drive assembly and a cam assembly, wherein the first drive assembly is mounted on the frame 1 and the cam assembly is mounted on the output end of the first drive assembly.

[0046] like Figure 10 , Figure 11 As shown, the first drive assembly includes a worm gear reducer 49 and a drive motor 410. The worm gear reducer 49 is fixedly mounted on the frame 1, and the drive motor 410 is fixedly mounted on the housing of the worm gear reducer 49. The output shaft of the drive motor 410 is fixedly connected to the input end of the worm gear reducer 49.

[0047] The cam assembly includes: a drive rod 411, a three-quarter cam 412, a half cam 413, and a quarter cam 414. The drive rod 411 is rotatably connected to the frame 1, and its middle side is fixedly connected to the output end of the worm gear reducer 49. Two three-quarter cams 412 are fixedly installed on the left and right sides of the drive rod 411, two quarter cams 414 are fixedly installed on the middle side of the drive rod 411, and two half cams 413 are fixedly installed on the drive rod 411. The half cam 413 is located between the three-quarter cams 412 and the quarter cams 414. Each of the three-quarter cams 412, half cams 413, and quarter cams 414 corresponds to a rotating frame 42.

[0048] When the amount of fertilizer in the uniform feeding mechanism 3 decreases and the overall weight of the fertilizing equipment becomes lighter, the output end of the drive motor 410 of the first drive component rotates, causing the transmission rod 411 to rotate by a preset angle. The rotation of the transmission rod 411 causes the three-quarter cam 412, the half cam 413, and the quarter cam 414 to rotate simultaneously. The three-quarter cam 412 rotates forty-five degrees, lifting one side of the outermost rotating frame 42, causing the outermost rotating frame 42 to rotate by a preset angle, raising the roller 46. At this time, the entire frame 1 is subjected to the pressure exerted by the two rollers 46, allowing the equipment to continue fertilizing within the preset depth. When the amount of fertilizer continues to decrease and the overall weight of the fertilizing equipment becomes lighter again, the output end of the drive motor 410 rotates, causing the transmission rod 411 to rotate by a preset angle. The three-quarter cam 412, the half cam 413, and the quarter cam 414 rotate simultaneously. When the 3rd and quarter cams 414 rotate simultaneously, and the three-quarter cam 412 rotates forty-five degrees, the outermost rotating frame 42 remains suspended. In contrast, the rotating frame 42 corresponding to the half cam 413 rotates. After rotating to a preset angle, the roller 46 rises. At this time, the entire frame 1 is subjected to the pressure applied by the four rollers 46. As it continues to rotate, the protruding end of the quarter cam 414 contacts the rotating frame 42, lifting the rotating frame 42. At this time, the entire frame 1 is subjected to the pressure applied by the six rollers 46. This facilitates the rapid adjustment of the pressure applied to the equipment during operation, preventing the trenching and backfilling mechanism 2 from being suspended, which would result in insufficient trenching depth or backfilling failure, leading to fertilizer waste. At the same time, it allows the equipment to adapt to different ground hardness levels. The pressure adjustment mechanism 4 can be activated periodically according to the distance traveled by the equipment to achieve automatic adjustment of the downward pressure.

[0049] Example 2: In some embodiments, such as Figures 1-11 As shown, in a preferred embodiment of the present invention, the uniform feeding mechanism 3 includes: a reciprocating sweeping component and a second driving component. The reciprocating sweeping component is mounted on the frame 1, and the second driving component is mounted on one side of the frame 1.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8As shown, the reciprocating sweeping assembly includes: a material box 31, a reciprocating screw 32, a second guide rod 33, a connecting seat 34, an L-shaped plate 35, and a cleaning rod 36. The material box 31 is fixedly installed on the frame 1. The left and right ends of the reciprocating screw 32 are rotatably connected to the frame 1. The second guide rod 33 is fixedly installed on the frame 1. The inner wall of the connecting seat 34 is slidably connected to the thread groove of the reciprocating screw 32 through a rotatably connected slider. The L-shaped plate 35 is slidably connected to the second guide rod 33. One side of the connecting seat 34 is fixedly connected to the L-shaped plate 35. The cleaning rod 36 is fixedly installed on the L-shaped plate 35. The end of the cleaning rod 36 away from the L-shaped plate 35 is located inside the material box 31. The bottom of the material box 31 is V-shaped, which is conducive to material discharge. Multiple fertilizer dischargers 37 are fixedly installed at the bottom of the material box 31 for uniform fertilizer conveying.

[0051] The second drive assembly includes: a driven rubber guide wheel 38, an electric push cylinder 39, an auxiliary rubber guide wheel 310, and a driving rubber guide wheel 311. The driven rubber guide wheel 38 is fixedly connected to one end of the reciprocating screw 32. The electric push cylinder 39 is fixedly mounted on the frame 1. The auxiliary rubber guide wheel 310 is rotatably connected to the output end of the electric push cylinder 39 via a rotating shaft. The driving rubber guide wheel 311 is rotatably connected to the frame 1 via a rotating shaft.

[0052] The linkage transmission mechanism 5 transmits the power generated by the movement of the trenching and backfilling mechanism 2 to the active rubber guide wheel 311 of the second drive component of the uniform material conveying mechanism 3. The output end of the electric push cylinder 39 extends, driving the auxiliary rubber guide wheel 310 to move upward. One side of the auxiliary rubber guide wheel 310 is in contact with the driven rubber guide wheel 38, and the other side of the auxiliary rubber guide wheel 310 is in contact with the active rubber guide wheel 311. The rotation of the auxiliary rubber guide wheel 310 drives the rotation of the driven rubber guide wheel 38, and the rotation of the driven rubber guide wheel 38 drives the rotation of the reciprocating screw 32. 2. Rotation drives the connecting seat 34 to move left and right. The left and right movement of the connecting seat 34 drives the L-shaped plate 35 to move left and right. The left and right movement of the L-shaped plate 35 drives the cleaning rod 36 to move left and right. The fertilizer in the auxiliary material box 31 is spread evenly in the material box 31. The second guide rod 33 assists the L-shaped plate 35 to move left and right, preventing the L-shaped plate 35 from rotating when it moves left and right. When the fertilizer in the material box 31 is almost empty, the cleaning rod 36 moves left and right to sweep the fertilizer into the fertilizer discharger 37, preventing fertilizer from remaining in the material box 31. The fertilizer discharger 37 evenly discharges the fertilizer into the trenching and backfilling mechanism 2, which is conducive to assisting in even spreading of the material and preventing fertilizer from being squeezed and remaining at the bottom of the material box 31.

[0053] Example 3: In some embodiments, such as Figures 1-11As shown, in a preferred embodiment of the present invention, the trenching and backfilling mechanism 2 includes a trenching component and a backfilling component. A plurality of trenching components are installed on the front side of the frame 1, and a plurality of backfilling components are installed on the middle side of the frame 1. The trenching components and the backfilling components correspond one-to-one.

[0054] like Figure 6 , Figure 7 As shown, the trenching assembly includes: vertical rods 21, arc blades 22, and a feeding pipe 23. Multiple vertical rods 21 are fixedly installed on the frame 1. Each vertical rod 21 is rotatably connected to two arc blades 22 via a rotating shaft. The distance between the rear sides of the two arc blades 22 is greater than the distance between their front sides. One end of the feeding pipe 23 is fixedly installed on the vertical rod 21. The end of the feeding pipe 23 closest to the vertical rod 21 is located behind the two arc blades 22. The end of the feeding pipe 23 furthest from the vertical rod 21 is fixedly connected to the output end of the fertilizer applicator 37.

[0055] When the fertilization equipment moves forward, the ditching component arc blade 22 of the ditching and backfilling mechanism 2 moves forward. The arc blade 22 is subjected to the pressure of the frame 1, which causes it to penetrate into the soil within the preset depth range. The fertilizer discharger 37 discharges fertilizer into the feeding pipe 23. The fertilizer enters between the two arc blades 22 from the feeding pipe 23. The arc blades 22 open a trench of a certain depth in the soil. At this time, the fertilizer enters the trench, which is conducive to the fertilizer penetrating into the soil and avoids fertilizer volatilization. At the same time, the fertilizer penetrating into the ground is conducive to crop absorption.

[0056] like Figure 9 As shown, the backfill assembly includes: a support frame 24, a compaction wheel 25, a support rod 26, and a second spring 27. One end of the support frame 24 is rotatably connected to the middle side of the frame 1 via a rotating shaft. The compaction wheel 25 is rotatably connected to the end of the support frame 24 away from the frame 1 via a rotating shaft. One end of the support rod 26 is rotatably connected to the support frame 24 via a rotating shaft. The end of the support rod 26 away from the support frame 24 is slidably connected to the frame 1. The second spring 27 is sleeved on the support rod 26. One end of the second spring 27 is tightly attached to the support frame 24, and the other end of the second spring 27 is tightly attached to the frame 1.

[0057] Roller 46 and compaction roller 25 are not on the same line to avoid roller 46 affecting compaction roller 25. At the same time, fertilization is carried out between multiple rows of wheat seedlings, so roller 46 can be moved to a position between wheat seedlings that have not been fertilized.

[0058] When fertilizer enters the trench, the compaction wheel 25 of the backfill component rolls forward, compacting the trench and sealing the fertilizer into the soil. The compaction wheel 25 receives pressure from the frame 1, allowing it to move up and down slightly. The up and down movement of the compaction wheel 25 causes the support frame 24 to rotate, the support rod 26 to move, and the second spring 27 to undergo elastic deformation. The compaction wheel 25 always keeps in contact with the ground when rolling on uneven land, which helps it adapt to uneven terrain.

[0059] like Figure 7 As shown, the linkage transmission mechanism 5 includes: a first sprocket 51, a second sprocket 52, a third sprocket 53, a fourth sprocket 54, and a fifth sprocket 55.

The first sprocket 51 and the second sprocket 52 are connected by chain drive, the second sprocket 52 and the third sprocket 53 are connected by chain drive, and the fourth sprocket 54 and the fifth sprocket 55 are connected by chain drive.

[0060] The compaction wheel 25 rotates, causing the first sprocket 51 to rotate. The rotation of the first sprocket 51 causes the second sprocket 52 to rotate. The rotation of the second sprocket 52 causes the third sprocket 53 to rotate. The rotation of the three sprockets causes the fertilizer discharge device 37 to start. The start of the fertilizer discharge device 37 causes the fourth sprocket 54 to rotate. The rotation of the fourth sprocket 54 causes the fifth sprocket 55 to rotate. The rotation of the fifth sprocket 55 causes the active rubber guide wheel 311 to rotate. The power of the compaction wheel 25 of the trenching and backfilling mechanism 2 is transmitted to the fertilizer discharge device 37 and the reciprocating sweeping component of the uniform material conveying mechanism 3.

[0061] A protective railing 6 is fixedly installed at the rear of the frame 1, and a support frame 7 is hinged to the middle side of the frame 1. The support frame 7 allows workers to sit down and rest, and the protective railing 6 prevents bagged fertilizer from falling when the equipment is moved. Multiple distance sensors and miniature cameras can be installed at the bottom of the frame 1. The distance sensors and miniature cameras are electrically connected to an external controller. The multiple distance sensors detect the distance between the frame 1 and the ground and transmit electrical signals to the external controller. At the same time, the camera, in conjunction with a vision recognition system, identifies the depth and width of the trench. The external controller controls the pressure regulating mechanism 4 to apply an appropriate pressure level, thereby achieving intelligent adjustment of the pressure and maintaining a suitable fertilization depth.
