Description

Technical Field

[0001] This invention belongs to the field of agricultural planting technology, and in particular relates to a multi-layer fertilization device and method for corn planting. Background Technology

[0002] Corn, also known as maize, is one of the world's highest-yielding crops and is widely used in food, feed, chemical, pharmaceutical and energy fields. During the planting period, corn requires scientific fertilization because its growth period is relatively long (usually 120-160 days) and it has a high demand for nutrients, especially nitrogen, making it a typical "high-nitrogen crop".

[0003] Currently, for corn-growing fields in hilly terrain, trench fertilization is often used to improve fertilizer utilization and reduce nutrient loss. Traditional corn trench fertilization typically requires manual labor or simple digging tools to dig fertilization trenches between rows of corn, apply fertilizer into the trenches, and finally cover it with soil. While this method can improve fertilizer utilization to some extent, it has significant drawbacks: operators need to frequently bend over, which can easily lead to back strain over long periods, and the labor intensity is high; furthermore, the three processes of trenching, fertilization, and covering are difficult to complete simultaneously, resulting in a lengthy process and low fertilization efficiency. Summary of the Invention

[0004] This invention provides a multi-layer fertilization device and method for corn planting, aiming to solve the problems mentioned in the background art, such as the high labor intensity of traditional corn trench fertilization operations, the tendency of operators to bend over for long periods of time, which can easily cause lumbar strain, and the inability to complete the three processes of trenching, fertilization, and covering soil simultaneously, resulting in long operation time and low fertilization efficiency.

[0008] Preferably, the multi-layer fertilization equipment for corn planting further includes a stirring mechanism installed on the fourth rotating shaft and the two sleeves. The stirring mechanism is used to break up the soil. The stirring mechanism includes: a fifth gear fixedly sleeved on the fourth rotating shaft; two sixth gears fixedly sleeved on the two sleeves respectively, both of which mesh with the fifth gear; and multiple stirring rods fixedly installed on the two sleeves respectively.

[0009] Preferably, the multi-layer fertilization equipment for corn planting further includes a soil pressing mechanism installed on the housing. The soil pressing mechanism is used to compress the soil.

[0011] Preferably, a feeding pipe for dispensing soil is fixedly installed on one side of the housing, and one end of the feeding pipe extends into the interior of the storage tank.

[0012] Preferably, a second strip-shaped hole is provided on one side of the housing, and an indicator rod is provided inside the second strip-shaped hole. One end of the indicator rod is fixedly connected to one side of the first fixing plate, and a scale is fixedly installed on one side of the housing, with the scale located on one side of the indicator rod.

[0013] Preferably, a hopper for dispensing fertilizer is fixedly installed on the top of the box, the hopper is connected to the interior of the first cavity, and handrails are fixedly installed on both sides of the shell.

[0014] The present invention also provides a method for using a multi-layer fertilization device for corn planting, comprising the following steps: Step 1: Preparation. Move the equipment to the corn planting area using the handrail. Then, pour the required fertilizer into the first chamber from the hopper. Next, take some soil from the ground and put it into the storage box through the feeding pipe. Then, start the hydraulic cylinder to drive the first fixed plate to slide vertically on the support rod. The first fixed plate will drive the first cylinder to rise and fall. At this time, the second rotating shaft connected to the first cylinder will simultaneously drive the sleeve to slide on the rectangular rod. The first fixed plate will also drive the second fixed plate to slide on the shell. The second fixed plate will drive the first U-shaped plate, the first rotating shaft, the roller and multiple crushing blades to rise and fall, so that multiple crushing blades can enter the ground at the corresponding depth according to the fertilization needs. Step Two: Ditching, fertilizing, and covering the cornfield with soil are carried out. During operation, the motor is started, and the equipment moves across the soil between two rows of corn. During this movement, multiple crushing blades rotate rapidly, ditching the cornfield and breaking up the soil. The motor drives a rectangular rod via a third shaft, which in turn drives a second shaft via a sleeve. This second shaft then drives the first helical blades. The crushed soil enters the first cylinder through the inlet and is then transported to the top of the first cylinder by the rotation of the first helical blades. From there, it is discharged into the storage tank through a pipe. During this process, the solenoid valves on the two fertilizer pipes need to be opened. Once opened, the fertilizer in the first chamber will be discharged through the two fertilizer pipes, fertilizing the dug fertilization trenches. Simultaneously with fertilization, the rectangular rod... The third gear on the rod drives the fourth gear to rotate, which in turn drives the fifth shaft to rotate on the housing. The fifth shaft then drives the seventh gear, which in turn drives the corresponding hollow tube to rotate via one of the second gears. This second gear's rotation, in turn, drives the fourth shaft to rotate on the storage box via the first gear. The first gear's rotation, in turn, drives another hollow tube via another second gear. This allows both hollow tubes to simultaneously drive the two second spiral blades to rotate, discharging the soil from the storage box through the bottom of the two discharge pipes. Due to the positional relationship between the two fertilizer pipes and the two discharge pipes, a process of spreading a layer of fertilizer, covering it with a layer of soil, then spreading another layer of fertilizer, and then covering it with another layer of soil can be achieved, thus realizing multi-layer fertilization. Finally, under the pressure of the soil compaction mechanism, the loose soil can be flattened, completing the fertilization process.

[0015] Compared with related technologies, the multi-layer fertilization equipment and method for corn planting provided by the present invention have the following beneficial effects: Compared with existing technologies, the multi-layer fertilization equipment and method for corn planting provided in this solution utilizes hydraulic cylinders to adjust the depth of the crushing blades inserted into the ground, allowing the blades to penetrate to the appropriate depth according to fertilization needs. The motor not only drives multiple crushing blades to rotate rapidly, enabling them to dig trenches in the corn planting area, but also drives the first spiral blades to rotate, allowing the crushed soil to enter the first cylinder through the inlet and then be discharged into the storage tank through the pipe. During this process, the fertilization mechanism can be activated to fertilize the excavated trenches. Simultaneously, the soil discharge mechanism, driven by the motor, expels soil from the bottom of the storage tank. The end-discharge system, with its fertilization and soil removal mechanisms, allows for layering fertilizer, covering with soil, and repeating this process multiple times. Compared to traditional single-layer fertilization, this multi-layer method better distributes nutrients to both deep and surface soils, enabling the corn's multi-layered root system to absorb nutrients evenly, resulting in better fertilization. Furthermore, because this equipment can simultaneously perform trenching, fertilization, and soil covering, it effectively solves the problems of high labor intensity, back strain caused by prolonged bending, and the inability to complete the three processes simultaneously, leading to long operation times and low fertilization efficiency in traditional corn trenching operations.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a multi-layer fertilization device for corn planting, such as... Figure 1-10As shown, a multi-layer fertilization device for corn planting includes: a shell 1, with a support rod 2 fixedly installed on the inner wall of the shell 1; a hydraulic cylinder 3 fixedly installed on the top inner wall of the shell 1, with a first fixing plate 4 fixedly installed on the output rod of the hydraulic cylinder 3, the first fixing plate 4 being slidably connected to the support rod 2; a second fixing plate 5 slidably installed on the shell 1, the top of the second fixing plate 5 being fixedly connected to the bottom of the first fixing plate 4, a first U-shaped plate 6 fixedly installed on the bottom of the second fixing plate 5, a first rotating shaft 7 rotatably installed on the first U-shaped plate 6, a roller 8 fixedly sleeved on the first rotating shaft 7, and multiple crushing blades 9 for digging fertilization trenches fixedly installed on the roller 8; a first cylinder 10 slidably installed on the shell 1, with a soil inlet on the first cylinder 10, and two baffles 11 fixedly installed on the outer wall of the first cylinder 10. A through pipe 21 is fixedly installed on a cylindrical body 10; a storage box 22 for storing soil is fixedly installed on the housing 1, the storage box 22 has a first strip-shaped hole, the first strip-shaped hole is located outside the through pipe 21; a second rotating shaft 12 is rotatably installed on the first cylindrical body 10, a first spiral blade 13 is fixedly sleeved on the second rotating shaft 12, a sleeve 14 is fixedly installed at the top of the second rotating shaft 12, and a rectangular rod 15 is slidably installed on the sleeve 14; a third rotating shaft 16 is rotatably installed on the housing 1, the bottom end of the third rotating shaft 16 is fixedly connected to the top end of the rectangular rod 15; a motor 17 is fixedly installed on the top of the housing 1, the output shaft of the motor 17 is fixedly connected to the top end of the third rotating shaft 16; a fertilizer application mechanism for corn planting is installed on the housing 1; and a soil discharge mechanism for covering the fertilizer trench with soil is assembled on the storage box 22.

[0020] In this embodiment, during use, the device is first moved to the cornfield, then the required fertilizer is added to the first cavity 19. Next, a portion of soil is taken from the ground and placed into the storage box 22. Then, the hydraulic cylinder 3 is activated, causing the first fixing plate 4 to slide vertically on the support rod 2. The first fixing plate 4 causes the first cylinder 10 to rise and fall. At this time, the second rotating shaft 12, which is rotatably connected to the first cylinder 10, simultaneously causes the sleeve 14 to slide on the rectangular rod 15. The first fixing plate 4 also causes the second fixing plate 5 to slide on the housing 1. The second fixing plate 5 then causes the first U-shaped plate 6 and the first rotating shaft 7 to move. The roller 8 and multiple crushing blades 9 are raised and lowered, allowing the crushing blades 9 to enter the ground at the appropriate depth according to fertilization needs. Then, the motor 17 is started, propelling the equipment across the soil between two rows of corn. During this movement, the multiple crushing blades 9 rotate rapidly, creating furrows in the cornfield and breaking up the soil. The motor 17 drives the rectangular rod 15 to rotate via the third shaft 16. The rectangular rod 15 then drives the second shaft 12 to rotate via the sleeve 14, causing the second shaft 12 to rotate the first spiral blade 13. At this time, the broken soil enters the first spiral blade 13 through the inlet. Inside the cylinder 10, the broken soil is transported to the top of the cylinder 10 by the rotation of the first spiral blade 13, and then discharged into the storage tank 22 through the pipe 21. During this process, the fertilization mechanism needs to be activated to fertilize the excavated fertilization trench. At the same time, the soil discharge mechanism, driven by the motor 17, discharges the soil from the bottom of the storage tank 22. Due to the design of the fertilization and soil discharge mechanisms, a multi-layer fertilization process can be achieved by spreading a layer of fertilizer, covering it with a layer of soil, then spreading another layer of fertilizer, and then covering it with another layer of soil. Compared to traditional single-layer fertilization, this method can better distribute nutrients from the fertilizer to both the deep and top layers of soil, allowing the multi-layered root system of corn to absorb nutrients evenly, resulting in better fertilization. Finally, the soil compaction mechanism flattens the loose soil, completing the fertilization process. Because this equipment can perform trenching, fertilization, and covering simultaneously, it effectively solves the problems of high labor intensity, back strain caused by prolonged bending of operators, and the inability to complete the three processes of trenching, fertilization, and covering simultaneously, as well as the long operation time and low fertilization efficiency.

[0021] In a further preferred embodiment of the present invention, the fertilization mechanism includes: a box 18 fixedly installed on the housing 1, the box 18 having a first cavity 19 for storing fertilizer; two fertilizer pipes 20 fixedly installed at the bottom of the box 18, both fertilizer pipes 20 communicating with the interior of the first cavity 19, and both fertilizer pipes 20 being equipped with solenoid valves.

[0022] In this embodiment, when fertilizing the corn planting area using the fertilization mechanism, the solenoid valves on the two fertilization pipes 20 are opened. After the solenoid valves are opened, the fertilizer in the first chamber 19 will be discharged from the two fertilization pipes 20 to fertilize the excavated fertilization trench. Fertilization is relatively simple. By cooperating with the soil discharge mechanism, multi-layer fertilization of the soil can be achieved, which can better provide the nutrients in the fertilizer to the deep soil and the surface soil respectively, and the fertilization effect is better.

[0023] In a further preferred embodiment of the present invention, the soil discharge mechanism includes: a fourth rotating shaft 23 rotatably mounted on the storage tank 22, on which a first gear 24 is fixedly sleeved; two sleeves 25 rotatably mounted on the storage tank 22, each sleeve 25 having a hollow tube 26 rotatably mounted on its inner wall; two second gears 27 fixedly sleeved on the two hollow tubes 26, each second gear 27 meshing with the first gear 24; a third gear 29 fixedly sleeved on the rectangular rod 15; and rotatably mounted... A fifth rotating shaft 28 is mounted on the housing 1, on which a fourth gear 30 is fixedly mounted and meshes with a third gear 29; a seventh gear 46 is fixedly mounted on the fifth rotating shaft 28 and meshes with one of the second gears 27; two discharge pipes 31 are fixedly installed at the bottom of the storage box 22; and two second spiral blades 32 are fixedly mounted on the two hollow tubes 26 respectively, with the two second spiral blades 32 located inside the two discharge pipes 31 respectively.

[0024] In this embodiment, the soil discharge mechanism is used to cover the fertilizer trench with soil. During the fertilization process, the third gear 29 on the rectangular rod 15 drives the fourth gear 30 to rotate. The fourth gear 30 drives the fifth rotating shaft 28 to rotate on the housing 1. The fifth rotating shaft 28 drives the seventh gear 46 to rotate. The seventh gear 46 drives the corresponding hollow tube 26 to rotate through one of the second gears 27. Under the rotation of this second gear 27, the fourth rotating shaft 23 can be driven to rotate on the storage box 22 through the first gear 24. Under the rotation of the first gear 24, another hollow tube 26 can be driven to rotate through the other second gear 27. Thus, the two hollow tubes 26 can simultaneously drive the two second spiral blades 32 to rotate, which can discharge the soil in the storage box 22 from the bottom of the two discharge pipes 31. Due to the positional relationship between the two fertilizer pipes 20 and the two discharge pipes 31, a layer of fertilizer can be spread, a layer of soil can be covered, then another layer of fertilizer can be spread, and then another layer of soil can be covered, realizing multi-layer fertilization. This allows the multi-layer root system of corn to absorb nutrients in the soil evenly, resulting in better utilization.

[0025] In a further preferred embodiment of the present invention, the multi-layer fertilization device for corn planting further includes a stirring mechanism installed on the fourth rotating shaft 23 and the two sleeves 25. The stirring mechanism is used to break up the soil. The stirring mechanism includes: a fifth gear 33 fixedly sleeved on the fourth rotating shaft 23; two sixth gears 34 respectively fixedly sleeved on the two sleeves 25, both of which mesh with the fifth gear 33; and a plurality of stirring rods 35 respectively fixedly installed on the two sleeves 25.

[0026] In this embodiment, the stirring mechanism is used to break up the soil. When the fourth rotating shaft 23 rotates on the storage tank 22, the fifth gear 33 with a larger diameter will drive the two sixth gears 34 with a smaller diameter to rotate, thereby driving the two sleeves 25 to rotate quickly. The two sleeves 25 drive the multiple stirring rods 35 to rotate quickly, which beats and stirs the soil that enters the storage tank 22, making the soil finer and more evenly distributed in the storage tank 22.

[0027] In a further preferred embodiment of the present invention, the multi-layer fertilization equipment for corn planting further includes a soil pressing mechanism installed on the housing 1. The soil pressing mechanism is used to compress the soil. The soil pressing mechanism includes: a fixed frame 36 fixedly installed at the bottom of the housing 1, a rotating block 37 rotatably installed on the fixed frame 36, a second U-shaped plate 38 fixedly installed on the rotating block 37, and a pressure roller 39 rotatably installed on the second U-shaped plate 38; a pressure plate 40 fixedly installed on the second U-shaped plate 38, a spring 41 fixedly installed on the pressure plate 40, a connecting plate 42 fixedly installed on the top of the spring 41, and one side of the connecting plate 42 fixedly connected to the outer wall of the housing 1; and a telescopic sleeve 43 fixedly installed between the pressure plate 40 and the connecting plate 42, the telescopic sleeve 43 being located outside the spring 41.

[0028] In this embodiment, during the movement of the device, the spring 41 will apply a large force to the pressure plate 40. The pressure plate 40 will drive the rotating block 37 to rotate adaptively on the fixed frame 36 through the second U-shaped plate 38, thereby enabling the pressure roller 39 to flatten the soil after fertilization with corresponding pressure. The squeezing effect is good. In long-term use, the telescopic sleeve 43 will always protect the spring 41 inside, thereby reducing the impact of the external environment on the spring 41.

[0029] In a further preferred embodiment of the present invention, a partition 44 for blocking the first strip hole is fixedly sleeved on the through pipe 21. The partition 44 is located on one side of the first strip hole and is in contact with one side of the storage box 22.

[0030] In this embodiment, the use of the first strip hole allows the pipe 21 to move up and down inside the storage box 22 as the first cylinder 10 moves up and down. The use of the partition 44 prevents the soil inside the storage box 22 from leaking out through the first strip hole.

[0031] In a further preferred embodiment of the present invention, a feeding pipe 45 for dispensing soil is fixedly installed on one side of the housing 1, and one end of the feeding pipe 45 extends into the interior of the storage box 22.

[0032] In this embodiment, the use of the feeding pipe 45 allows personnel to easily take a portion of soil from the ground and put it into the storage tank 22, so that when the equipment is running, there is some usable soil in the storage tank 22, in case the two discharge pipes 31 cannot discharge soil at the same time when the equipment is running.

[0033] In a further preferred embodiment of the present invention, a second strip-shaped hole is provided on one side of the housing 1, and an indicator rod 75 is provided inside the second strip-shaped hole. One end of the indicator rod 75 is fixedly connected to one side of the first fixing plate 4, and a scale 76 is fixedly installed on one side of the housing 1. The scale 76 is located on one side of the indicator rod 75.

[0034] In this embodiment, when the hydraulic cylinder 3 drives the first fixed plate 4 to rise and fall, the indicator rod 75 connected to it will move synchronously in the second strip hole, and then point to the corresponding position of the scale 76. According to the position of the indicator rod 75 pointing to the scale 76, it is convenient for personnel to adjust the depth of the breaker blade 9 into the ground more accurately.

[0035] In a further preferred embodiment of the present invention, a hopper for dispensing fertilizer is fixedly installed on the top of the box 18, the hopper is connected to the interior of the first cavity 19, and handrails are fixedly installed on both sides of the shell 1.

[0036] In this embodiment, the use of the hopper allows personnel to easily add the fertilizer needed into the first cavity 19, and the use of the handrail allows personnel to easily push the device, and also allows two people to work together to move the device from some difficult-to-move ground to the desired placement location.

[0037] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a plurality of rolling mechanisms are installed on the housing 1. The rolling mechanism includes: a side plate 47 fixedly installed on the bottom of the housing 1, a rotating rod 48 rotatably installed on the side plate 47, a sliding sleeve 49 slidably sleeved on the rotating rod 48, and a traveling wheel 50 fixedly sleeved on the sliding sleeve 49; and a bolt 51 threadedly installed on the sliding sleeve 49, the bolt 51 being adapted to any one of the slots on the rotating rod 48.

[0038] In this embodiment, when the worker pushes the device to move, the walking wheels 50 will roll on the ground, making the device easier to move. When it is necessary to adjust the position of the walking wheels 50, first use a tool to unscrew the bolt 51 from the sliding sleeve 49, so that the bolt 51 is disengaged from the inserted slot. Then, by adjusting the position of the sliding sleeve 49 on the rotating rod 48, the walking wheels 50 can be adjusted to the required position. Then, use a tool to tighten the bolt 51 onto the sliding sleeve 49, so that the bolt 51 is inserted into the corresponding slot, thereby fixing the position of the walking wheels 50. Since the position of the walking wheels 50 can be adjusted, the position of the walking wheels 50 can be adjusted according to the corn planting situation to prevent the equipment from crushing the corn during movement.

[0039] In another embodiment of the present invention, an irrigation mechanism is installed on the housing 18 for watering the soil. The irrigation mechanism includes: a second cavity 62 disposed within the housing 18 for storing water; a second cylinder 52 fixedly installed on the top of the housing 18, on which a water-drawing pipe 53 is fixedly installed, one end of which extends into the interior of the second cavity 62, and a first one-way valve is provided on the water-drawing pipe 53; and a diversion pipe 54 fixedly installed on the housing 18, one end of which is fixedly connected to the second cylinder 52 and communicates with the interior of the second cylinder 52, and a second one-way valve is provided on the diversion pipe 54; A U-shaped rod 55 is installed on the top of the housing 18. A limit block 56 is slidably installed on the U-shaped rod 55. A crossbar 57 is fixedly installed on the limit block 56. A piston 58 is fixedly installed at one end of the crossbar 57. The piston 58 is slidably connected to the inner wall of the second cylinder 52. A connecting rod 59 is rotatably installed on the crossbar 57. A circular plate 60 is rotatably installed on the connecting rod 59. The bottom of the circular plate 60 is fixedly connected to the top end of the fifth rotating shaft 28. Two drain pipes 61 are fixedly installed on the diversion pipe 54. One end of each drain pipe 61 is rotatably connected to the top end of each of the two hollow pipes 26. Two nozzles 63 are fixedly installed at the bottom ends of each of the two hollow pipes 26.

[0040] In this embodiment, the irrigation mechanism is used to water the soil. When the fifth rotating shaft 28 rotates, it drives the circular plate 60 to rotate, which in turn drives the connecting rod 59 to swing. The connecting rod 59 then drives the crossbar 57 to move back and forth. At the same time, the limiting block 56, which is fixed to the crossbar 57, slides back and forth on the U-shaped rod 55. Under the reciprocating movement of the crossbar 57, the piston 58 can slide back and forth in the second cylinder 52. During the reciprocating sliding of the piston 58, the water pumping pipe 53 will transport the water in the second cavity 62 to the second cylinder 52. The water is squeezed into the diversion pipe 54 by the piston 58, and then transported from the two drain pipes 61 to the two hollow pipes 26, and then sprayed out from the two nozzles 63. This allows water to be sprayed onto the fertilized and covered ground, increasing soil moisture, enabling the fertilizer to dissolve quickly and disperse nutrients into the soil, so that the nutrients in the fertilizer can be utilized quickly and the effect is better. Because the pumping pipe 53 is equipped with a first one-way valve and the diversion pipe 54 is equipped with a second one-way valve, backflow of water can be prevented, so that water can only flow in one direction of the pumping pipe 53 and the diversion pipe 54.

[0041] In another embodiment of the present invention, a driving mechanism is installed on the first cylinder 10. The driving mechanism is used to rotate the first rotating shaft 7, the roller 8, and a plurality of crushing blades 9. The driving mechanism includes: a support frame 64 fixedly installed on the top of the first cylinder 10, the support frame 64 being rotatably connected to the second rotating shaft 12, and a sixth rotating shaft 65 rotatably installed on the support frame 64; a first bevel gear 66 fixedly sleeved on the second rotating shaft 12; a second bevel gear 67 fixedly installed on the sixth rotating shaft 65, the second bevel gear 67 meshing with the first bevel gear 66; and a fixedly installed... The third bevel gear 68 is mounted on the sixth rotating shaft 65; a support plate 69 is fixedly mounted on the support frame 64, and a seventh rotating shaft 70 is rotatably mounted on the support plate 69, the seventh rotating shaft 70 being slidably connected to the third strip hole on the housing 1; a fourth bevel gear 71 is fixedly sleeved on the seventh rotating shaft 70, the fourth bevel gear 71 meshing with the third bevel gear 68; a first sprocket 72 is fixedly sleeved on the seventh rotating shaft 70; a second sprocket 73 is fixedly sleeved on the first rotating shaft 7; and a chain 74 is sleeved on the first sprocket 72 and the second sprocket 73.

[0042] In this embodiment, the drive mechanism is used to rotate the first rotating shaft 7, the roller 8, and the multiple crushing blades 9. When the first cylinder 10 moves, the support frame 64 connected to it moves synchronously, causing the seventh rotating shaft 70 to move inside the third slot. Consequently, when adjusting the height of the crushing blades 9, the positions of the first sprocket 72, the second sprocket 73, and the chain 74 are also adjusted synchronously. When the second rotating shaft 12 rotates, the first bevel gear 66, which is fixedly sleeved on the second rotating shaft 12, rotates. The first bevel gear 66 drives the sixth rotating shaft 65 on the support frame 64 through the second bevel gear 67. The rotation of the sixth shaft 65 drives the third bevel gear 68 to rotate, which in turn drives the seventh shaft 70 to rotate on the support plate 69 via the fourth bevel gear 71. The seventh shaft 70 then drives the first sprocket 72 to rotate, which in turn drives the second sprocket 73 to rotate via the chain 74. The second sprocket 73 then drives the first shaft 7 to rotate on the first U-shaped plate 6, which in turn drives the roller 8 to rotate. The roller 8 then drives multiple crushing blades 9 to rotate rapidly, thus breaking up the soil and making it easy to dig ditches in cornfields.

[0043] In another embodiment of the present invention, a water inlet pipe is fixedly installed on the top of the box 18, the water inlet pipe is provided with a cover, and the bottom end of the water inlet pipe extends into the interior of the second cavity 62.

[0044] In this embodiment, the water supply pipe allows for convenient addition of water to the second cavity 62. When water needs to be added, simply remove the cover from the water supply pipe to add water to the second cavity 62. After adding water, cover the water supply pipe with the cover.

[0045] The present invention also provides a method for using a multi-layer fertilization device for corn planting, comprising the following steps: Step 1: Preparation. Move the equipment to the corn planting area using the handrail. Then, pour the required fertilizer from the hopper into the first chamber 19. Next, take some soil from the ground and put it into the storage box 22 through the feeding pipe 45. Then, start the hydraulic cylinder 3 to drive the first fixed plate 4 to slide vertically on the support rod 2. The first fixed plate 4 will drive the first cylinder 10 to rise and fall. At this time, the second rotating shaft 12, which is rotatably connected to the first cylinder 10, will simultaneously drive the sleeve 14 to slide on the rectangular rod 15. The first fixed plate 4 will also drive the second fixed plate 5 to slide on the shell 1. The second fixed plate 5 will drive the first U-shaped plate 6, the first rotating shaft 7, the roller 8 and multiple crushing blades 9 to rise and fall, so that the multiple crushing blades 9 can enter the ground at the corresponding depth according to the fertilization needs. Step Two: Ditching, fertilizing, and covering the cornfield with soil are carried out. During operation, motor 17 is started, propelling the equipment across the soil between two rows of corn. During this movement, multiple crushing blades 9 rotate rapidly, ditching the cornfield and breaking up the soil. Motor 17 drives rectangular rod 15 via third shaft 16, which in turn drives second shaft 12 via sleeve 14. This second shaft 12 then drives first spiral blade 13. The broken soil enters the first cylinder 10 through the inlet and is then transported to the top of the first cylinder 10 by the rotation of the first spiral blade 13. The soil is then discharged into storage tank 22 through pipe 21. During this process, the solenoid valves on the two fertilizer pipes 20 are opened. Once opened, fertilizer from the first chamber 19 is discharged through the two fertilizer pipes 20, fertilizing the dug fertilization trenches. Simultaneously, the rectangular rod 15... The third gear 29 drives the fourth gear 30 to rotate, which in turn drives the fifth shaft 28 to rotate on the housing 1. The fifth shaft 28 drives the seventh gear 46 to rotate, which in turn drives the corresponding hollow tube 26 to rotate via one of the second gears 27. Under the rotation of this second gear 27, the fourth shaft 23 can be driven to rotate on the storage box 22 via the first gear 24. Under the rotation of the first gear 24, another hollow tube 26 can be driven to rotate via the other second gear 27. This allows both hollow tubes 26 to simultaneously drive the two second spiral blades 32 to rotate, discharging the soil from the storage box 22 from the bottom of the two discharge pipes 31. Due to the positional relationship between the two fertilizer pipes 20 and the two discharge pipes 31, a process of spreading a layer of fertilizer, covering it with a layer of soil, then spreading another layer of fertilizer, and then covering it with another layer of soil can be achieved, thus realizing multi-layer fertilization. Finally, under the compression of the soil compaction mechanism, the loose soil can be flattened, completing the fertilization work.

[0046] In summary, compared with related technologies, this solution, through the use of hydraulic cylinder 3, can adjust the depth of the crusher blade 9 inserted into the ground, allowing it to enter the ground at the appropriate depth according to fertilization needs. The motor 17 not only drives multiple crusher blades 9 to rotate rapidly, enabling them to dig trenches in the cornfield, but also drives the first spiral blade 13 to rotate, allowing the crushed soil to enter the first cylinder 10 through the inlet and then be discharged into the storage tank 22 through the pipe 21. During this process, the fertilization mechanism can be activated to fertilize the excavated fertilization trenches. Simultaneously, the soil discharge mechanism, driven by motor 17, can discharge soil from the storage tank 22. The fertilizer is discharged from the bottom of box 22. Due to the setting of the fertilizer application mechanism and the soil discharge mechanism, it can form a process of spreading a layer of fertilizer, covering a layer of soil, spreading another layer of fertilizer, and covering another layer of soil to achieve multi-layer fertilization. Compared with the traditional single-layer fertilization method, this multi-layer fertilization method can better provide the nutrients in the fertilizer to the deep soil and the surface soil, so that the multi-layer root system of corn can evenly absorb the nutrients in the soil, resulting in better fertilization effect. Since this equipment can perform trenching, fertilization and soil covering work at the same time, it effectively solves the problems of high labor intensity, long bending time causing back strain for operators, and the inability to complete the three processes of trenching, fertilization and soil covering simultaneously, as well as the long operation time and low fertilization efficiency.

Move the equipment to the corn planting area using the handrail. Then, pour the required fertilizer into the first chamber from the hopper. Next, take some soil from the ground and put it into the storage box through the feeding pipe. Then, start the hydraulic cylinder to drive the first fixed plate to slide vertically on the support rod. The first fixed plate will drive the first cylinder to rise and fall. At this time, the second rotating shaft connected to the first cylinder will simultaneously drive the sleeve to slide on the rectangular rod. The first fixed plate will also drive the second fixed plate to slide on the shell. The second fixed plate will drive the first U-shaped plate, the first rotating shaft, the roller and multiple crushing blades to rise and fall, so that multiple crushing blades can enter the ground at the corresponding depth according to the fertilization needs. Step Two: Ditching, fertilizing, and covering the cornfield with soil are carried out. During operation, the motor is started, and the equipment moves across the soil between two rows of corn. During this movement, multiple crushing blades rotate rapidly, ditching the cornfield and breaking up the soil. The motor drives a rectangular rod via a third shaft, which in turn drives a second shaft via a sleeve. This second shaft then drives the first helical blades. The crushed soil enters the first cylinder through the inlet and is then transported to the top of the first cylinder by the rotation of the first helical blades.

Simultaneously with fertilization, the rectangular rod... The third gear on the rod drives the fourth gear to rotate, which in turn drives the fifth shaft to rotate on the housing. The fifth shaft then drives the seventh gear, which in turn drives the corresponding hollow tube to rotate via one of the second gears. This second gear's rotation, in turn, drives the fourth shaft to rotate on the storage box via the first gear. The first gear's rotation, in turn, drives another hollow tube via another second gear.

Due to the positional relationship between the two fertilizer pipes and the two discharge pipes, a process of spreading a layer of fertilizer, covering it with a layer of soil, then spreading another layer of fertilizer, and then covering it with another layer of soil can be achieved, thus realizing multi-layer fertilization. Finally, under the pressure of the soil compaction mechanism, the loose soil can be flattened, completing the fertilization process.
