Description

Technical Field

[0001] This invention relates to the field of no-till fertilizing planter technology, specifically to a no-till fertilizing planter and a method for fertilizing and planting corn. Background Technology

[0002] Corn stalks are erect, usually unbranched, 1-4 meters tall, with aerial prop roots at the base of each node. Leaves are flat and broad, linear-lanceolate, with orange-yellow anthers. Caryopsis is spherical or oblate, its size varying depending on growing conditions. Flowering and fruiting occur in autumn. It is cultivated throughout China and widely grown in tropical and temperate regions worldwide, serving as an important grain. Corn yield is directly related to the quality of the topsoil. Current methods of fertilizer application in my country, such as broadcasting and strip application, result in high fertilizer usage and low fertilizer utilization, leading to low soil porosity and high bulk density, severely restricting further yield increases.

[0003] No-till seeding and fertilization involves directly sowing and fertilizing after crop harvest, when stubble and straw remain on the surface. Less no-till refers to the area of ​​soil disturbed; no-till seeding and fertilization machines that disturb less soil are called less-till seeding and fertilization machines. The width of a no-till seeding and fertilization machine refers to the working width across which the machine covers several rows as it moves forward to perform sowing and fertilization operations. A wider width results in higher efficiency in fertilization and sowing, better meeting the needs of today's increasingly large-scale farming. Generally, a rotary tillage width not exceeding 40% of the machine's width constitutes no-till seeding.

[0004] During operation, the no-till fertilizer planter experiences shaking or bumps, causing the planter drive to rotate at a normal, uniform speed while the planter itself stops briefly. After prolonged operation, this leads to a mismatch between fertilizer dispensing and sowing speeds, resulting in fertilizer falling before the seeds. Furthermore, while existing fertilizer dispensing systems have metering devices at the pipe inlet to prevent blockage, when fertilizer levels are low, the planter's vibrations cause the fertilizer to sway within the storage tank, leading to insufficient fertilizer application each time, uneven fertilization, and even a lack of synchronization between fertilization and sowing speeds. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a no-till fertilizing planter and a method for fertilizing and planting corn. It overcomes the problem that when fertilizer is scarce, the planter's vibrations cause the fertilizer to move around within the storage tank, resulting in insufficient fertilizer application and uneven fertilization.

[0017] A method for fertilizing and planting corn, which utilizes a no-till fertilizing planter.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a no-till fertilizing planter and a method for fertilizing and planting corn, which has the following beneficial effects:

[0020] 1. This no-till fertilizer planter, through the setting of the shaking separation component, when the frame vibrates during travel, the vibration of the frame transmits power to the shaking separation component. At this time, under the elasticity of the elastic mounting rod, the transmission wheel and the drive wheel separate, and the distribution shaft briefly stops rotating. Simultaneously, the fertilizer in the fertilizer box bounces up due to the vibration of the frame, causing some fertilizer to fail to fall into the distribution component. Through the action of the shaking separation component, the distribution shaft stops rotating synchronously, thus synchronizing with the state of the fertilizer inside the fertilizer box, making the fertilizer more evenly distributed when passing through the distribution component. Then, the guided component guides the distributed fertilizer into the fertilization component for fertilization, avoiding the phenomenon of fertilizer bouncing up and causing uneven fertilization due to vibration of the frame during fertilization.

[0021] 2. This no-till fertilizer planter uses a reversing drive shaft directly connected to the tail of the drive shaft in the power drive mechanism to drive a synchronous drive component. The synchronous drive component can be a sprocket structure. The reversing drive shaft reverses the power of the drive shaft and transmits it to the sprocket-structured synchronous drive component. The sprocket-structured synchronous drive component drives the shaft and drive wheel to rotate, thereby matching the transmission speed of the drive wheel with the travel speed of the machine frame. This ensures that during fertilization, the fertilizer always follows the forward speed of the machine frame, and the fertilizer is evenly distributed. This ensures that the amount of fertilizer applied each time matches the sowing speed of the sowing unit, avoiding interruptions or misalignments in fertilization and sowing due to the shaking of the machine frame during travel, thus ensuring synchronization of fertilization and sowing.

[0022] 3. This no-till fertilizer planter divides the fertilizer box into two independent spaces by a grid inside the fertilizer box, storing two different types of fertilizer. Then, the two different types of fertilizer are distributed by a dispensing component under each independent space. The conical protrusion inside the fertilizer box at the bottom can cause the fertilizer in the fertilizer box to gather at the dispensing component when the amount of fertilizer in the fertilizer box is small.

[0023] 4. This no-till fertilizer planter connects to the fertilizer box via a main guide pipe. The main guide pipe houses the branch pipes and the main distribution shaft. A linkage mechanism drives the main distribution shaft to rotate, which in turn drives the branch pipes around the main guide pipe via a mounting plate. Each branch pipe passes under the distribution assembly, allowing the two distribution assemblies to disperse fertilizer into each branch pipe. The distribution assembly rotates the fertilizer in the space between the two distribution plates from facing inwards towards the fertilizer box to facing downwards. When one branch pipe passes under the distribution assembly for one type of fertilizer, that fertilizer falls into it. As the main distribution shaft rotates, the branch pipe continues to rotate forward, and then the next branch pipe rotates to the bottom of the same distribution assembly. With the continued rotation of the main distribution shaft, the branch pipe carrying one type of fertilizer rotates to the bottom of the distribution assembly for another type of fertilizer. The other distribution assembly then guides the fertilizer into the branch pipe carrying the first type of fertilizer in the same way. The fertilizer dispensing mechanism involves a dispensing port located below the previous dispensing component in the moving direction. When the guiding pipe moves to the front of a fertilizer dispensing component, it discharges the fertilizer inside. Then it moves to the bottom of that fertilizer dispensing component. When the guiding pipe moves to the bottom of another fertilizer dispensing component and completes the dispensing of that fertilizer, it continues moving forward to the dispensing port to discharge the fertilizer, completing one dispensing cycle. The driven shaft drives the linkage shaft to rotate. When the linkage shaft rotates, the drive worm rotates coaxially, which in turn drives the worm wheels on both sides to rotate. One worm wheel drives the fertilizer application main shaft on one side, and the other worm wheel drives the transmission gear at the bottom of the drive worm to rotate, which in turn drives the dispensing main shaft to rotate. The cooperation between the transmission gear and the worm wheel ensures that the rotation direction of the dispensing main shaft is opposite to that of the fertilizer application main shaft, thus ensuring that the amount of fertilizer discharged by the dispensing and guiding components is uniform each time, avoiding uneven fertilization.

[0035] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-10 A no-till fertilizing seeder includes a frame 1, on which a power drive mechanism 2, a fertilizing mechanism 3, and a sowing unit 4 are sequentially mounted. The power drive mechanism 2 drives the fertilizing mechanism 3 through a linkage mechanism 5. The fertilizing mechanism 3 includes a distributing component 31, a guiding component 32, a fertilizing component 33, a shaking separation component 34, and a fertilizer box 35. Fertilizer is distributed to the guiding component 32 by the distributing component 31, and the guiding component 32 sequentially guides the fertilizer into the fertilizing component 33. The distributing component 31 includes a distributing shaft 311 and a distributing deflector 312. The distributing deflector 312 is located at the bottom of the fertilizer box 35, and the distributing shaft 311 is connected to the distributing deflector 312. The rod 311 is connected to the shaking separation assembly 34. A drive wheel 7 is provided on one side of the frame 1. The drive wheel 7 is connected to the power drive mechanism 2 through a shaft. The shaking separation assembly 34 includes a transmission wheel 341 and an elastic mounting rod 342. The elastic mounting rod 342 connects the transmission wheel 341 to the frame 1. The transmission wheel 341 is connected to the drive wheel 7. The drive wheel 7 drives the material distribution shaft 311 to rotate through the transmission wheel 341. The material distribution baffle 312 rotates at the bottom of the fertilizer box 35. When the frame 1 shakes, the transmission wheel 341 shakes with the frame 1 under the action of the elastic mounting rod 342, and the transmission wheel 341 separates from the drive wheel 7.

[0037] When in use, the frame 1 is installed at the head and tail of an external tractor or similar machine; a torsion spring-like elastic structure is provided at the rotatable connection between the elastic mounting rod 342 and the frame 1.

[0038] As the machine head moves the frame 1 forward, the power drive mechanism 2 drives the fertilizer applicator 3 through the linkage mechanism 5. First, the dispensing component 31 in the fertilizer applicator 3 moves with the frame 1. The drive wheel 7 on one side of the frame 1 rotates under the drive of the power drive mechanism 2 via the shaft. The drive wheel 7 drives the transmission wheel 341 in contact with it to rotate. Under the elastic force of the elastic mounting rod 342, the transmission wheel 341 is in close contact with the drive wheel 7. Then, the transmission wheel 341 drives the dispensing shaft 311 to rotate. The dispensing shafts 311 in both dispensing components 31 rotate, which in turn drives the dispensing baffle 312 to rotate at the bottom of the fertilizer box 35, quantitatively separating the two types of fertilizer within the fertilizer box 35. When the frame 1 experiences bumps during travel, the frame 1 shakes... The power is transmitted to the shaking separation component 34. At this time, under the elasticity of the elastic mounting rod 342, the transmission wheel 341 separates from the drive wheel 7, and the distribution shaft 311 briefly stops rotating. At the same time, the fertilizer in the fertilizer box 35 bounces up due to the shaking of the frame 1, causing some fertilizer to fail to fall into the distribution component 31. Through the action of the shaking separation component 34, the distribution shaft 311 stops rotating synchronously, thus synchronizing with the state of the fertilizer inside the fertilizer box 35, making the fertilizer more evenly distributed when it passes through the distribution component 31. Then, the distributed fertilizer is guided into the fertilization component 33 for fertilization through the guiding component 32, avoiding the phenomenon of fertilizer bouncing up and causing uneven fertilization due to the bumps of the frame 1 during the movement of the machine.

[0039] Furthermore, the fertilizer box 35 is located above the frame 1. A grid plate 351 is installed inside the fertilizer box 35, and the grid plate 351 is horizontally positioned inside the fertilizer box 35. The distributing component 31 is located at the bottom of the grid plate 351. Several conical protrusions 352 are provided at the lower part of the fertilizer box 35, located on both sides of the grid plate 351. The grid plate 351 inside the fertilizer box 35 divides the fertilizer box 35 into two independent spaces for storing two different fertilizers. The distributing component 31 in each independent space then distributes the two different fertilizers. The conical protrusions 352 at the lower part of the fertilizer box 35 allow fertilizer to accumulate towards the distributing component 31 when the amount inside the fertilizer box 35 is low.

[0040] Furthermore, the shaking separation assembly 34 also includes a synchronous pulley 343, which is located at one end of each of the two sets of material distribution shafts 311. A synchronous belt 344 is provided between the synchronous pulleys 343, and a transmission belt 345 is provided outside one of the synchronous pulleys 343. The other end of the transmission belt 345 is connected to the transmission wheel 341, which is located above and in contact with the drive wheel 7 on one side. The synchronous pulley 343 in the shaking separation assembly 34 is connected to the transmission wheel 341 via the transmission belt 345. When the drive wheel 7 drives the transmission wheel 341 to rotate, the transmission wheel 341 drives the synchronous pulley 343 to rotate via the transmission belt 345. Thus, the two synchronous pulleys 343 rotate synchronously via the synchronous belt 344. The two synchronously rotating synchronous pulleys 343 respectively drive the material distribution shafts 311 connected to them to rotate, thereby separating the two types of fertilizer inside the fertilizer box 35.

[0041] Furthermore, a coaxial wheel 346 is provided on one side of the transmission wheel 341, and the coaxial wheel 346 is connected to the transmission belt 345. An arc-shaped guide ring 347 is provided on the other side of the transmission wheel 341. The arc-shaped guide ring 347 is formed on the frame 1. A guide rod 348 is provided on the axis of one side of the transmission wheel 341. The guide rod 348 is slidably connected to the arc-shaped guide ring 347. The center of the arc-shaped guide ring 347 is coaxial with the material distribution shaft 311. One end of the elastic mounting rod 342 is installed on the outside of the material distribution shaft 311. It is rotatably connected to the outside of the frame 1; through the coaxial wheel 346 provided on one side of the transmission wheel 341, under the drive of the transmission belt 345, the coaxial wheel 346 drives a synchronous wheel 343 to rotate, and then the synchronous wheel 343 drives another synchronous wheel 343 to rotate synchronously through the synchronous belt 344; when the frame 1 shakes, the transmission wheel 341 swings around the material distribution shaft 311 as the axis and the arc-shaped guide ring 347 as the path under the action of the elastic mounting rod 342. When swinging, the guide rod 348 on one side of the transmission wheel 341 slides in the arc-shaped guide ring 347.

[0042] Furthermore, the guiding component 32 includes a main guiding pipe 321, a branch guiding pipe 322, and a distributing main shaft 323. The main guiding pipe 321 is located below the fertilizer box 35 and is positioned directly opposite the bottom of the distributing component 31. The distributing main shaft 323 is located inside the main guiding pipe 321 and extends above it. The end of the distributing main shaft 323 is connected to the linkage mechanism 5.

[0043] Furthermore, the branch pipes 322 are located inside the main branch pipe 321. Each group of branch pipes 322 comprises several units, evenly distributed inside the main branch pipe 321. A support disc 324 is provided at the bottom of each branch pipe 322, and the support disc 324 is fixed to the inner wall of the main branch pipe 321. A dispensing port 325 is provided on the support disc 324, and the dispensing port 325 is the same size as one of the branch pipes 322. An mounting plate 3231 is provided in the middle of the dispensing spindle 323, and the branch pipes 322 are mounted on the mounting plate. On 3231, the main guide pipe 321 extends upward above the mounting plate 3231; it is connected to the fertilizer box 35 via the main guide pipe 321. The main guide pipe 321 is used to install the branch pipes 322 and the dispensing spindle 323. The linkage mechanism 5 drives the dispensing spindle 323 to rotate, which in turn drives the branch pipes 322 to rotate around the main guide pipe 321 via the mounting plate 3231. This causes each branch pipe 322 to pass through the bottom of the dispensing assembly 31, dispersing fertilizer into each branch pipe 322 from the two dispensing assemblies 31. The component 31 rotates the fertilizer in the space between the two dispensing plates 312 from facing inwards to facing downwards. When one of the dispensing pipes 322 passes the bottom of the dispensing component 31 for one type of fertilizer, the fertilizer falls into the dispensing pipe 322. Then, as the dispensing main shaft 323 rotates, the dispensing pipe 322 continues to rotate forward, and then the next dispensing pipe 322 rotates to the bottom of the dispensing component 31. As the dispensing main shaft 323 continues to rotate, the dispensing pipe 322 carrying one type of fertilizer rotates to the bottom of the dispensing component 31 for another type of fertilizer, and the other dispensing component 31... In this manner, the fertilizer is introduced into the dispensing pipe 322 containing one type of fertilizer to complete the quantitative dispensing of the fertilizer. The dispensing port 325 is located below the dispensing component 31 in the moving direction. When the dispensing pipe 322 moves to the dispensing component 31 of one type of fertilizer, the fertilizer inside it is discharged, and then it moves to the bottom of the dispensing component 31 of that fertilizer. When the dispensing pipe 322 moves to the bottom of the dispensing component 31 of another type of fertilizer and completes the dispensing of the other type of fertilizer, it continues to move forward and moves to the dispensing port 325 to discharge the fertilizer, completing one cycle of dispensing.

[0044] Further, the fertilization assembly 33 includes a fertilization spindle 331, a sealing plate 332 is provided above the fertilization spindle 331, a discharge port 333 is provided on the sealing plate 332, and a discharge pipe 334 is provided at the bottom of the discharge port 333; a hoe-type furrow opener 6 is provided on one side of the discharge pipe 334, the hoe-type furrow opener 6 is installed at the front end of the frame 1, and a protective buckle 335 is provided on the outside of the discharge pipe 334, one end of the protective buckle 335 is installed on the hoe-type furrow opener 6; through the fertilization spindle 331 above... The sealing plate 332 blocks the upper drainage pipe 322. When the discharge port 333 on the sealing plate 332 rotates to align with the distribution port 325, the fertilizer inside the drainage pipe 322 can be discharged from the distribution port 325 and the discharge port 333 and enter the discharge pipe 334. The time it takes for the discharge port 333 and the distribution port 325 to rotate from separation to alignment is the time interval for fertilization. Then the fertilizer is discharged from the bottom of the discharge pipe 334. Before discharge, a trench is opened on the ground by a hoe-type trencher 6 so that the fertilizer can enter the soil.

[0045] Further, the power drive mechanism 2 includes a drive shaft 21, a universal joint 22, a driven shaft 23, and a reversing reducer 24; the drive shaft 21 and the driven shaft 23 are connected by the reversing reducer 24, and the universal joint 22 is provided between the driven shaft 23 and the reversing reducer 24; after passing through the reversing reducer 24, the power of the drive shaft 21 is output to the linkage mechanism 5 through the driven shaft 23; a reversing transmission shaft 26 is provided at the tail of the drive shaft 21, and a synchronous drive component 25 is provided at the bottom of the reversing transmission shaft 26; the bottom end of the synchronous drive component 25 is connected to a shaft drive via a shaft. Drive wheel 7; connected to an external power source via drive shaft 21 in power drive mechanism 2. Drive shaft 21 drives driven shaft 23 to rotate via reversing reducer 24. Driven shaft 23 drives linkage mechanism 5 via universal joint 22. Driven synchronous drive component 25 is driven to rotate via reversing transmission shaft 26 directly connected to the tail of drive shaft 21. Synchronous drive component 25 can be a sprocket structure. Reversing transmission shaft 26 reverses the power of drive shaft 21 and transmits it to sprocket structure synchronous drive component 25. Sprocket structure synchronous drive component 25 drives shaft and drive wheel 7 to rotate, thereby making the transmission speed of drive wheel 7 match the travel speed of frame 1.

[0046] Furthermore, the linkage mechanism 5 also includes a linkage shaft 51, which passes between the two sets of material dispensing components 31. The linkage shaft 51 is connected to one side of the driven shaft 23 via a belt. Several drive worm gears 52 are mounted on the linkage shaft 51, and worm wheels 53 are respectively mounted on both sides of each drive worm gear 52. One worm wheel 53 is mounted on the fertilizer main shaft 331, and the other worm wheel 53 is located at the bottom of the drive worm gear 52. A transmission gear 54 is mounted below the drive worm gear 52. On shaft 323, the transmission gear 54 meshes with the worm gear 53; the driven shaft 23 drives the linkage shaft 51 to rotate. When the linkage shaft 51 rotates, the drive worm 52 rotates coaxially, thereby driving the worm gears 53 on both sides to rotate. This causes one worm gear 53 to drive the fertilizer main shaft 331 on one side, and the other worm gear 53 to drive the transmission gear 54 at the bottom of the drive worm 52 to rotate, thereby driving the material distribution main shaft 323 to rotate. The cooperation between the transmission gear 54 and the worm gear 53 makes the rotation direction of the material distribution main shaft 323 opposite to the rotation direction of the fertilizer main shaft 331.

[0047] A method for fertilizing and planting corn, which utilizes a no-till fertilizing planter.

[0048] Working principle: During use, two different fertilizers are poured into the grid plates 351 inside the fertilizer box 35 on both sides. As the machine head drives the frame 1 forward, the power drive mechanism 2 drives the fertilizer application mechanism 3 through the linkage mechanism 5. The reversing drive shaft 26 directly connected to the tail of the drive shaft 21 in the power drive mechanism 2 drives the synchronous drive component 25 to rotate. The synchronous drive component 25 can be a sprocket structure. The reversing drive shaft 26 reverses the power of the drive shaft 21 and transmits it to the sprocket structure synchronous drive component 25. The sprocket structure synchronous drive component 25 drives the shaft and drive wheel 7 to rotate, thereby making the transmission speed of the drive wheel 7 match the travel speed of the frame 1.

[0049] First, as the frame 1 moves, the drive wheel 7 on one side of the frame 1 rotates under the drive of the power drive mechanism 2 via the shaft. The drive wheel 7 drives the transmission wheel 341 in contact with it to rotate. Under the elastic force of the elastic mounting rod 342, the transmission wheel 341 is in close contact with the drive wheel 7. Then, the transmission wheel 341 drives the distribution shaft 311 to rotate. The distribution shaft 311 in the two distribution components 31 rotates, which in turn drives the distribution plate 312 to rotate at the bottom of the fertilizer box 35, quantitatively separating the two types of fertilizer in the fertilizer box 35. The fertilizer box 35 is divided into two independent spaces by the grid plate 351 set inside the fertilizer box 35 to store the two different types of fertilizer. The two different types of fertilizer are then distributed by the distribution component 31 set under each independent space. The conical protrusion 352 set at the bottom inside the fertilizer box 35 can cause the fertilizer in the fertilizer box 35 to gather towards the distribution component 31 when there is less fertilizer.

[0050] When the frame 1 experiences bumps during operation, the shaking transmits power to the shaking separation component 34. At this time, due to the elasticity of the elastic mounting rod 342, the transmission wheel 341 separates from the drive wheel 7, causing the distributing shaft 311 to briefly stop rotating. Simultaneously, the fertilizer inside the fertilizer box 35 bounces up due to the shaking of the frame 1, preventing some fertilizer from falling into the distributing component 31. Through the action of the shaking separation component 34, the distributing shaft 311 stops rotating synchronously, thus synchronizing with the state of the fertilizer inside the fertilizer box 35, allowing the fertilizer to... The material is distributed more evenly through the material distribution component 31; the synchronous wheel 343 in the shaking separation component 34 is connected to the transmission wheel 341 by the transmission belt 345. When the drive wheel 7 drives the transmission wheel 341 to rotate, the transmission wheel 341 drives the synchronous wheel 343 to rotate through the transmission belt 345. Then, the two synchronous wheels 343 rotate synchronously through the synchronous belt 344. The two synchronously rotating synchronous wheels 343 drive the material distribution shaft 311 connected to them to rotate, and respectively process the two types of fertilizer inside the fertilizer box 35.

[0051] During the swinging process of the transmission wheel 341, the coaxial wheel 346 set on one side of the transmission wheel 341 drives a synchronous wheel 343 to rotate under the drive of the transmission belt 345. Then, the synchronous wheel 343 drives another synchronous wheel 343 to rotate synchronously through the synchronous belt 344. When the frame 1 shakes, the transmission wheel 341 swings around the material distribution shaft 311 as the axis and the arc-shaped guide ring 347 as the path under the action of the elastic mounting rod 342. During the swinging process, the guide rod 348 on one side of the transmission wheel 341 slides in the arc-shaped guide ring 347.

[0052] The fertilizer is then guided into the fertilization component 33 via the guiding component 32 for fertilization. This prevents the fertilizer from bouncing up due to the vibration of the frame 1 during the fertilization process, which would cause uneven fertilization. It ensures that the fertilizer always follows the forward speed of the frame 1 during fertilization, and that the fertilizer is evenly distributed. This makes the amount of fertilizer applied each time match the sowing speed of the sowing unit 4, and avoids interruptions or confusion in fertilization and sowing due to the shaking of the frame 1 during the fertilization process. This ensures the synchronization of fertilization and sowing.

[0053] The fertilizer box 35 is connected to the main drainage pipe 321. Drainage branch pipes 322 and a dispensing main shaft 323 are installed on the main drainage pipe 321. A linkage mechanism 5 drives the dispensing main shaft 323 to rotate. The dispensing main shaft 323, through the mounting plate 3231, drives the drainage branch pipes 322 to rotate around the main drainage pipe 321. This causes each drainage branch pipe 322 to pass through the bottom of the dispensing assembly 31, distributing fertilizer into each drainage branch pipe 322. The dispensing assembly 31 rotates the fertilizer in the space between the two dispensing baffles 312 from facing inwards towards the fertilizer box 35 to facing downwards. When one drainage branch pipe 322 passes the bottom of the dispensing assembly 31 for a particular type of fertilizer, that fertilizer falls into the drainage branch pipe 322. Then, as the dispensing main shaft 323 rotates, the drainage branch pipe 322 continues to rotate forward, and then... One distribution pipe 322 rotates to the bottom of the distribution component 31. As the main shaft 323 continues to rotate, the distribution pipe 322 carrying one type of fertilizer rotates to the bottom of the distribution component 31 carrying another type of fertilizer. The other distribution component 31 guides the fertilizer into the distribution pipe 322 carrying one type of fertilizer in the same way, completing the quantitative distribution of fertilizer. The distribution port 325 is located below the first distribution component 31 in the direction of movement. When the distribution pipe 322 moves to the distribution component 31 carrying one type of fertilizer, it discharges the fertilizer inside and then moves to the bottom of the fertilizer distribution component 31. When the distribution pipe 322 moves to the bottom of the distribution component 31 carrying another type of fertilizer and completes the distribution of the other type of fertilizer, it continues to move forward and moves to the distribution port 325 to discharge the fertilizer, completing one cycle of distribution.

[0054] During the above process, the driven shaft 23 drives the linkage shaft 51 to rotate. When the linkage shaft 51 rotates, the drive worm 52 rotates coaxially, thereby driving the worm wheels 53 on both sides to rotate. This causes one worm wheel 53 to drive the fertilizer main shaft 331 on one side, and the other worm wheel 53 to drive the transmission gear 54 at the bottom of the drive worm 52 to rotate, thereby driving the material distribution main shaft 323 to rotate.

[0055] Then, the sealing plate 332 set above the fertilization main shaft 331 blocks the upper drainage pipe 322. When the discharge port 333 set on the sealing plate 332 rotates to align with the distribution port 325, the fertilizer inside the drainage pipe 322 can be discharged from the distribution port 325 and the discharge port 333 and enter the discharge pipe 334. The time it takes for the discharge port 333 and the distribution port 325 to rotate from separation to alignment is the time interval for fertilization. Then, the fertilizer is discharged from the bottom of the discharge pipe 334. Before discharge, the hoe-type trencher 6 opens a trench on the ground so that the fertilizer can enter the soil.
