Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a rotary tillage, fertilization and seeding machine. Background Technology

[0002] The rotary tiller-fertilizer-seeder is a combined machine that integrates rotary tiller and fertilizer-seeder. It combines multiple functions such as rotary tillage, sowing, and fertilization into one machine, which can quickly and effectively sow seeds of grain crops such as rapeseed, wheat, and corn, greatly improving the efficiency of agricultural cultivation.

[0003] Existing integrated seed and fertilizer machines typically include a frame, a fertilization mechanism, a sowing mechanism, and a rotary tillage mechanism. The fertilization mechanism generally adopts a box structure, storing fertilizer inside and conveying it quantitatively to the discharge port through a fertilizer roller. However, in actual agricultural production, it is often necessary to apply two or more different types of fertilizers simultaneously (such as urea granules for nitrogen fertilizer, granules for phosphate fertilizer, and potassium chloride granules for potassium fertilizer).

[0004] Existing fertilizer boxes are usually single-chamber structures, and different types of fertilizers are stored together, which can easily lead to problems such as layering and clumping, affecting the uniformity of fertilization. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a rotary tillage fertilizer seeder that solves the problem in the prior art where the fertilizer box is usually a single cavity structure, and different types of fertilizers are mixed and stored together, which easily leads to stratification and affects the uniformity of fertilization.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A rotary tillage fertilizer seeder includes a frame and a fertilization mechanism mounted on the frame. The fertilization mechanism includes a housing and a fertilization assembly. The housing is fixedly connected to the frame. The fertilization assembly includes a first drive component and multiple fertilization rollers arranged parallel to each other along the width direction of the housing. The multiple fertilization rollers are all drivenly connected to the first drive component. An adjustable main partition is provided inside the housing. The movement direction of the main partition is parallel to the length direction of the fertilization rollers. The main partition divides the housing into two storage areas, which are used to store different types of fertilizers.

[0008] By setting up the above structure, the main partition divides the container into two independent storage areas, storing different types of fertilizers separately. This avoids the problems of stratification and clumping caused by mixing different fertilizers, and improves the uniformity of fertilization. By changing the position of the main partition, the volume ratio of the two storage areas can be adjusted, thereby adjusting the fertilization ratio of different types of fertilizers.

[0009] Furthermore, a first fine-tuning component is installed on both sides of the main partition. The first fine-tuning component includes a moving plate, a first baffle, and a second driving member. The second driving member is fixedly installed on the main partition and is connected to the moving plate in a transmission manner. The second driving member is used to drive the moving plate to move along the length direction of the fertilizer roller. One end of the first baffle is rotatably connected to the moving plate, and the other end is slidably connected to the main partition. A partition is formed between the first baffle, the main partition, and the moving plate to separate the storage area from the fertilizer roller.

[0010] By setting up the above structure, the second driving component drives the moving plate to move, changing the contact length between the fertilizer roller and the fertilizer in the storage area, thus realizing online fine-tuning of the fertilizer application ratio.

[0011] Furthermore, the box is also equipped with multiple adjustable sub-partitions. The moving direction of the sub-partitions is parallel to the length direction of the fertilizer roller. A second fine-tuning component is installed on one side of the sub-partitions. The second fine-tuning component has the same structure as the first fine-tuning component.

[0012] By setting up the above structure and adding multiple secondary partitions, the container can be divided into more storage areas to meet the needs of applying multiple fertilizers at the same time, thus expanding the applicability of the equipment.

[0013] Furthermore, the bottom of the box is provided with multiple discharge boxes, each corresponding to a fertilizer roller. The fertilizer roller quantitatively transfers fertilizer from the storage area to the discharge box, and the bottom of the discharge box is connected to a fertilizer pipe.

[0014] By setting up the above structure, the discharge box works in conjunction with the fertilizer application tube to apply fertilizer directly into the soil, preventing fertilizer from scattering randomly and affecting the uniformity of fertilization.

[0015] Furthermore, it also includes a sowing mechanism mounted on the frame. The sowing mechanism includes a frame, a drive structure, and multiple sowing structures. The frame is fixedly connected to the frame. Each sowing structure includes a mounting base, a seed box, a mounting shell, a sowing wheel, a detection element, and a sealing assembly. The detection element is electrically connected to the sealing assembly. The mounting base is fixedly connected to the frame. The seed box is fixedly mounted on the mounting base for filling with seeds. The mounting shell is fixedly connected between the mounting base and the seed box. The top and bottom of the mounting shell are respectively provided with an inlet and an outlet. The inlet communicates with the outlet of the seed box. The sowing wheel is rotatably mounted inside the mounting shell. The outer wall of the seed wheel is fitted to the inner wall of the mounting shell. The seed wheel is connected to the drive structure for transmission. The circumference of the seed wheel is evenly provided with multiple first grooves and multiple second grooves. The first grooves and second grooves are arranged side by side. The detection element is installed on the outer wall of the mounting shell and is used to detect whether there are seeds in the first groove that rotates towards the discharge port. The sealing component is set at the discharge port. The inner wall of the sealing component is fitted to the outer wall of the seed wheel. The discharge port includes a first outlet and a second outlet. The first outlet corresponds to multiple first grooves, and the second outlet corresponds to multiple second grooves. The sealing component is used to seal the first outlet or the second outlet.

[0016] By setting up the above structure, when the detector detects that there are no seeds in the first groove, the sealing component opens the second groove and seals the first groove, and the seeds in the second groove are used directly for reseeding. This allows for reseeding of multiple sowing structures at the same time, with a fast response speed, effectively improving the uniformity and continuity of overall sowing.

[0017] Furthermore, the sealing assembly includes a sealing component and a third driving component. The mounting shell is provided with a mounting rod inside the discharge port. The mounting rod is arranged along the arrangement direction of the first groove and the second groove. The sealing component is slidably mounted on the mounting rod. The third driving component is fixedly mounted inside the mounting shell. The third driving component is connected to the sealing component in a transmission manner. The third driving component is used to drive the sealing component to slide along the mounting rod.

[0018] By setting up the above structure, the drive component can control the sealing component to move left and right, thereby opening or closing the first and second grooves. The structure is simple and the operation is quick.

[0019] Furthermore, the third driving component includes an electromagnet, a ferromagnetic component is mounted on the sealing component, and a return spring is sleeved on the mounting rod. The return spring is used to move the sealing component away from the electromagnet, and the electromagnet is used to move the sealing component closer to the electromagnet.

[0020] By setting up the above structure, the sealing component can respond quickly, ensuring the accuracy of the timing of replanting.

[0021] Furthermore, the detection component includes a detection box, a seed sensor, and a controller. The detection box is fixedly installed on the mounting shell, the seed sensor is installed inside the detection box, the mounting shell has a through hole penetrating the mounting shell, the detection end of the seed sensor is located inside the through hole, the controller is fixedly installed inside the detection box, and both the seed sensor and the sealing assembly are electrically connected to the controller.

[0022] Furthermore, it also includes a rotary tillage mechanism installed on the frame. The rotary tillage mechanism includes a rotary tiller installed on the frame. The tail of the rotary tiller is equipped with a second baffle. The second baffle has multiple slots. Soil raised by the rotary tiller passes through the slots and is scattered behind the second baffle.

[0023] By setting up the above structure, during operation, the soil raised by the rotary tiller passes through the trough and is scattered behind the second baffle to cover the seeds sown by the seeding mechanism. This achieves soil covering without increasing the weight of the equipment and improves the seed germination rate.

[0024] Furthermore, the rotary tillage mechanism also includes a reinforcing member, which is slidably mounted on the second baffle along the length of the groove. The second baffle is provided with a locking member, which is used to lock the reinforcing member on the second baffle. The end of the second baffle near the soil is provided with a plurality of protruding teeth, which correspond one-to-one with a plurality of grooves. The ends of the protruding teeth protrude from below the second baffle and are used to create grooves in the soil.

[0025] By setting the above structure, the reinforcing member can increase the strength of the second baffle and avoid affecting the service life of the second baffle due to the presence of multiple slots. By changing the position of the reinforcing member, the lowest position of the soil passing through the slot can be adjusted according to the actual situation, thereby controlling the soil throwing distance so that the thrown soil can fall on the seeds sown by the sowing mechanism. Furthermore, the sowing mechanism can further increase the depth of the seeds buried in the soil by sowing the seeds in the furrow.

[0026] The beneficial effects of this invention are:

[0027] 1. This invention utilizes a main partition and multiple fertilizer rollers parallel to the width of the container. The main partition divides the container into two independent storage areas, each storing different types of fertilizer. This avoids the problems of stratification and clumping caused by mixing different fertilizers, thus improving the uniformity of fertilization. By changing the position of the main partition, the volume ratio of the two storage areas can be adjusted, thereby regulating the fertilization ratio of different types of fertilizer.

[0028] 2. By setting a first fine-tuning component and a second driving component to drive the moving plate to move, the present invention changes the contact length between the fertilizer roller and the fertilizer in the storage area, thereby realizing online fine-tuning of the fertilizer application ratio.

[0029] 3. By setting a first groove, a second groove, and a sealing component, when the detection component detects that there are no seeds in the first groove, the sealing component opens the second groove and seals the first groove, and the seeds in the second groove are directly used for replanting. This invention can simultaneously replant multiple sowing structures, and the response speed is fast, effectively improving the uniformity and continuity of overall sowing.

[0030] 4. This invention achieves the opening or closing of the first and second grooves by setting a sealing component and a driving component. The driving component controls the left and right movement of the sealing component. The structure is simple and the operation is quick.

[0031] 5. The present invention opens multiple slots on the second baffle. During operation, the soil raised by the rotary tiller passes through the slots and is scattered behind the second baffle to cover the seeds sown by the sowing mechanism. This achieves soil covering without increasing the weight of the equipment and improves the seed germination rate. Attached Figure Description

[0052] 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.

[0053] like Figures 1-14 As shown, this embodiment of a rotary tillage and fertilization seeder includes a frame 1 and a fertilization mechanism 2, a seeding mechanism 3, and a rotary tillage mechanism 4 mounted on the frame 1. The fertilization mechanism 2 is used for quantitative fertilization, the seeding mechanism 3 is used for quantitative seeding, and the rotary tillage mechanism 4 is used for tilling the land. The fertilization position is located in front of the rotary tillage mechanism 4, and the seeding position is located behind the rotary tillage mechanism 4. That is, quantitative fertilization is performed first, the rotary tillage mechanism 4 mixes the soil with the fertilizer after tilling the land, and the seeding mechanism 3 sows the seeds in the fertilized and tilled soil.

[0054] In this embodiment, as Figures 1-5 The fertilization mechanism 2 includes a housing 21 and a fertilization assembly. The housing 21 is fixedly connected to the frame 1. The fertilization assembly includes a first drive component 22 and multiple fertilization rollers 23 arranged parallel to each other along the width direction of the housing 21. In this embodiment, multiple fertilization grooves 231 are evenly arranged around the circumference of the fertilization rollers 23, and these grooves are arranged along the length direction of the rollers. All the rollers 23 are connected to the first drive component 22, which drives them to rotate synchronously at the same speed. An adjustable main partition 24 is provided inside the housing 21. The main partition 24 moves parallel to the length direction of the fertilization rollers 23. The main partition 24 divides the housing 21 into two storage areas, which are used to store different types of fertilizers, thus avoiding stratification and clumping caused by mixing different fertilizers and improving the uniformity of fertilization.

[0055] In this embodiment, multiple slots 211 are provided at both ends of the inner wall of the box 21. These slots 211 are evenly distributed along the width of the box 21. Locking blocks 241 are fixedly provided at both ends of the main partition 24. The main partition 24 is fixed by locking the locking blocks 241 into the slots 211. The size of the two storage areas can be adjusted by inserting the locking blocks 241 into different slots 211. In this embodiment, a box cover 25 is provided on top of the box 21 to close the box 21 and limit the movement of the main partition 24 in the height direction of the box 21. Before filling with fertilizer, the volume ratio of the two storage areas can be adjusted by changing the position of the main partition 24, thereby adjusting the fertilization ratio of different types of fertilizer.

[0056] In this embodiment, a first fine-tuning component 26 is installed on both sides of the main partition 24. The first fine-tuning component 26 includes a moving plate 261, a first baffle 262, and a second driving member 263. The second driving member 263 is fixedly installed on the main partition 24 and is connected to the moving plate 261. The second driving member 263 is used to drive the moving plate 261 to move along the length direction of the fertilizer roller 23. One end of the first baffle 262 is rotatably connected to the moving plate 261, and the other end is slidably connected to the main partition 24. Specifically, a connecting rod 28 is rotatably installed at the end of the first baffle 262. A limit block 242 is fixedly installed on the main partition 24. The free end of the connecting rod 28 is slidably installed on the limit block 242. A partition is formed between the first baffle 262, the main partition 24, and the moving plate 261 to separate the storage area from the fertilizer roller 23. In use, the second driving component 263 drives the moving plate 261 to move, changing the contact length between the fertilizer roller 23 and the fertilizer in the storage area, thus realizing online fine-tuning of the fertilization ratio. For example, different plots in the same area may have similar fertilizer requirements, and the first fine-tuning component 26 can be used to fine-tune the fertilization ratio online, effectively improving the fertilization effect.

[0057] In this embodiment, the housing 21 is further provided with multiple adjustable sub-partitions 27. The moving direction of the sub-partitions 27 is parallel to the length direction of the fertilizer roller 23. A second fine-tuning component is installed on one side of the sub-partitions 27, and the second fine-tuning component has the same structure as the first fine-tuning component 26. By setting multiple sub-partitions 27, the housing 21 can be divided into more storage areas to meet the needs of simultaneous application of multiple fertilizers, thus expanding the applicability of the equipment.

[0058] In this embodiment, the bottom of the housing 21 is provided with multiple discharge boxes 212, each corresponding to a fertilizer roller 23. The fertilizer roller 23 quantitatively transfers fertilizer from the storage area into the discharge box 212. The bottom of the discharge box 212 is connected to a fertilizer pipe 213. The discharge box 212 and the fertilizer pipe 213 work together to apply fertilizer directly into the soil, preventing fertilizer from scattering randomly and affecting the uniformity of fertilization.

[0059] In this embodiment, as Figures 6-11As shown, the sowing mechanism 3 includes a frame 31, a drive structure 32, and multiple sowing structures 33. The frame 31 is fixedly connected to the frame 1. The sowing structures 33 are used for sowing, and the drive structure 32 is used to drive the multiple sowing structures 33 to sow simultaneously. The sowing structure 33 includes a mounting base 331, a seed box 332, a mounting shell 333, a sowing wheel 334, a detection element 335, and a sealing assembly 35. The detection element 335 is electrically connected to the sealing assembly 35. The mounting base 331 is fixedly connected to the frame 31. The seed box 332 is fixedly installed on the mounting base 331 for filling seeds. The mounting shell 333 is fixedly connected between the mounting base 331 and the seed box 332. The top and bottom of the mounting shell 333 are respectively provided with an inlet 336 and an outlet 337. The inlet 336 is connected to the outlet of the seed box 332.

[0060] The seeding wheel 334 is rotatably mounted inside the mounting housing 333. The outer wall of the seeding wheel 334 is in contact with the inner wall of the mounting housing 333. The seeding wheel 334 is connected to the drive structure 32. The circumference of the seeding wheel 334 is evenly provided with a plurality of first grooves 341 and a plurality of second grooves 342. The first grooves 341 and the second grooves 342 are arranged side by side. In this embodiment, the drive structure 32 includes a drive motor 321 and a drive shaft 322. The seeding wheel 334 is connected to the drive shaft 322. This embodiment does not limit the connection relationship between the seeding wheel 334 and the drive shaft 322. It can be detached and fixedly connected, interference fit, keyed connection, etc., as long as it can realize the synchronous transmission of multiple seeding wheels 334. When the drive shaft 322 rotates, it drives the sowing wheel 334 to rotate. When the first groove 341 and the second groove 342 on the sowing wheel 334 rotate to the feed inlet 336, the seeds in the seed box 332 fall into the first groove 341 and the second groove 342. When the first groove 341 and the second groove 342 on the sowing wheel 334 rotate to the discharge outlet 337, the seeds in the first groove 341 or the second groove 342 fall into the discharge outlet 337 for sowing. It should be noted that the dimensions of the first groove 341 and the second groove 342 are set according to the size of the seeds.

[0061] The detection element 335 is installed on the outer wall of the mounting housing 333 and is used to detect whether there are seeds in the first groove 341 that rotates towards the discharge port 337.

[0062] A sealing component 35 is disposed at the discharge port 337. The inner wall of the sealing component 35 is in contact with the outer wall of the seeding wheel 334. The discharge port 337 includes a first outlet 361 and a second outlet 362. The first outlet 361 corresponds to a plurality of first grooves 341, and the second outlet 362 corresponds to a plurality of second grooves 342. The sealing component 35 is used to seal the first outlet 361 or the second outlet 362. When the detection element 335 detects that there are no seeds in the first groove 341, the sealing component 35 opens the second groove 342 and seals the first groove 341, directly using the seeds in the second groove 342 for reseeding. This allows for simultaneous reseeding of multiple seeding structures 33 with a fast response speed, effectively improving the uniformity and continuity of overall seeding.

[0063] It should be noted that after the seeds in the second groove 342 are replanted, the sealing component 35 returns to the state of sealing the second outlet 362 and opening the first outlet 361.

[0064] In this embodiment, the sealing assembly 35 includes a sealing element 351 and a third driving element 352. An installation rod 37 is provided within the discharge port 337 of the mounting shell 333. The installation rod 37 is arranged along the arrangement direction of the first groove 341 and the second groove 342. Two installation rods 37 are provided. The sealing element 351 is slidably mounted on the installation rod 37. The third driving element 352 is fixedly mounted within the mounting shell 333 and is drively connected to the sealing element 351. The third driving element 352 is used to drive the sealing element 351 to slide along the installation rod 37. In other embodiments, the sealing assembly 35 can also be configured as two valves, corresponding to the first outlet 361 and the second outlet 362 respectively. In this embodiment, by setting the sealing element 351 and the third driving element 352, the driving element controls the left and right movement of the sealing element 351 to realize the opening or closing of the first groove 341 and the second groove 342. The structure is simple and the operation is quick.

[0065] In this embodiment, the sealing member 351 is provided with a waist-shaped groove 353, which is arranged along the arrangement direction of the first groove 341 and the second groove 342, that is, along the length direction of the seeding wheel 334. The waist-shaped groove 353 communicates with the first outlet 361 or the second outlet 362, effectively reducing the distance that the sealing member 351 needs to move.

[0066] In this embodiment, the third driving component 352 includes an electromagnet, and a ferromagnetic component 354, such as an iron block, steel, or iron-nickel alloy, is mounted on the sealing component 351. A return spring 371 is sleeved on the mounting rod 37. The return spring 371 is used to move the sealing component 351 away from the electromagnet, and the electromagnet is used to move the sealing component 351 closer to the electromagnet. In some other embodiments, the third driving component 352 can also be a cylinder, a linear motor, etc. By setting an electromagnet and a ferromagnetic component 354, the sealing component 351 can respond quickly, ensuring the accuracy of the replanting timing, and at a lower cost.

[0067] In this embodiment, two electromagnets are provided, respectively installed on the side walls of both ends of the mounting housing 333. Ferromagnetic components 354 are provided at both ends of the sealing member 351. When the sealing member 351 blocks the first outlet 361, the electromagnet at the left end is active, while the electromagnet at the right end is inactive. When the sealing member 351 blocks the second outlet 362, the electromagnet at the left end is inactive, while the electromagnet at the right end is active, preventing the sealing member 351 from moving arbitrarily. In some other embodiments, only the electromagnet at the left end may be provided.

[0068] In this embodiment, the detection component 335 includes a detection box 381, a seed sensor 382, ​​and a controller 383. The detection box 381 is fixedly installed on the mounting shell 333, and the seed sensor 382 is installed inside the detection box 381. The mounting shell 333 has a through hole penetrating through it, and the detection end of the seed sensor 382 is located inside the through hole. The controller 383 is fixedly installed inside the detection box 381. Both the seed sensor 382 and the sealing assembly 35 are electrically connected to the controller 383. In this embodiment, the controller 383 is preferably a PLC. In this embodiment, the seed sensor 382 is a photoelectric sensor. When the photoelectric sensor detects that there are no seeds in the first groove 341, the controller 383 controls the electromagnet of the sealing component 35 to work after a preset time, driving the sealing component 351 to open the second outlet 362 and close the first outlet 361, so that the seeds in the second groove 342 can be replanted. After the seeds in the second groove 342 are replanted, the controller controls the electromagnet of the sealing component 35 to work within a preset time after the seeds in the second groove 342 are replanted, so that the sealing component 351 opens the first outlet 361 and closes the second outlet 362.

[0069] Specifically, the distance between adjacent first grooves 341 is defined as the adjustment section. The first groove 341 without seeds is defined as the target groove. The position of the adjustment section is calculated using the rotation speed of the seeding wheel 334. When the adjustment section in front of the target groove rotates to the discharge port 337, the sealing member 351 is driven to open the second outlet 362 and close the first outlet 361. When the adjustment section behind the target groove rotates to the discharge port 337, the sealing member 351 is driven to open the first outlet 361 and close the second outlet 362.

[0070] In this embodiment, a retaining sleeve 39 is provided at the bottom of the discharge port 337. Both the first outlet 361 and the second outlet 362 are connected to the retaining sleeve 39, and a feeding pipe 391 is fixedly connected to the bottom of the retaining sleeve 39. This prevents seeds falling from the first outlet 361 or the second outlet 362 from scattering randomly, allowing the seeds to be smoothly delivered to the soil below the seeder via the feeding pipe 391. Furthermore, the retaining sleeve 39 protects the sealing component 35, preventing dust from entering the sealing component 35 and affecting its normal operation.

[0071] In this embodiment, a connecting seat is fixedly provided between the mounting shell 333 and the mounting base 331, and the mounting shell 333 is fixedly mounted on the mounting base 331 through the connecting seat.

[0072] In this embodiment, as Figures 12-14 As shown, the rotary tillage mechanism 4 includes a rotary tiller 41 mounted on the frame 1. The rotary tiller 41 is well-disclosed in the prior art and will not be described in detail here. A second baffle 42 is fitted to the tail of the rotary tiller 41; specifically, the second baffle 42 is mounted on the frame 1. On one hand, the second baffle 42 is used to level the soil after rotary tillage; on the other hand, it is used to block soil splashed during rotary tillage. The second baffle 42 has multiple slots 421, each corresponding to a feeding pipe 391 of the sowing mechanism 3. Soil lifted by the rotary tiller 41 passes through the slots 421 and is scattered behind the second baffle 42. During operation, the soil lifted by the rotary tiller 41 passes through the slots 421 and is scattered behind the second baffle 42, covering the seeds sown by the sowing mechanism 3, thereby achieving soil covering and improving seed germination rate without increasing the weight of the equipment.

[0073] In this embodiment, the rotary tillage mechanism 4 also includes a reinforcing member 43. In this embodiment, the reinforcing member 43 is plate-shaped. The reinforcing member 43 is used to strengthen the strength of the second baffle 42 and avoid affecting the service life of the baffle due to the presence of multiple slots 421.

[0074] In this embodiment, the reinforcing member 43 is slidably installed on the second baffle 42 along the length of the groove 421. A locking member 5 is provided on the second baffle 42 to lock the reinforcing member 43 onto the second baffle 42. By changing the position of the reinforcing member 43, the lowest position of the soil passing through the groove 421 can be adjusted according to actual conditions, thereby controlling the soil throwing distance. This ensures that the thrown soil lands on the seeds sown by the sowing mechanism 3, meaning the seeds sown by the sowing mechanism 3 first land on the soil, and then the thrown soil covers the seeds, with the landing point of the thrown soil behind the seed landing point. Furthermore, the amount of soil covering can be adjusted according to actual needs.

[0075] In this embodiment, the width of the reinforcing member 43 is greater than the length of the groove 421. When the soil surface moisture is sufficient and there is no need for covering with soil, the groove 421 can be completely sealed by the reinforcing member 43.

[0076] In this embodiment, the reinforcing member 43 has sliding grooves 431 on both sides, and the second baffle 42 has connecting posts 422 fixedly installed at both ends. The connecting posts 422 slide through the sliding grooves 431. The locking member 5 includes a locking bolt, which is threaded onto the connecting post 422. The locking bolt is used to lock the reinforcing member 43 onto the second baffle 42, thereby achieving a sliding connection between the reinforcing member 43 and the second baffle 42. In other embodiments, a sliding connection can also be achieved through the sliding grooves 431 and the slider or the sliding rod and the through hole.

[0077] In this embodiment, the second baffle 42 has multiple protruding teeth 44 at one end near the soil. Each protruding tooth 44 corresponds to a multiple slot 421. The ends of the protruding teeth 44 protrude below the second baffle 42 and are used to create grooves in the soil. The sowing mechanism 3 can sow seeds in the grooves, which can further increase the depth of seed burial in the soil.

[0078] In this embodiment, a mounting plate 45 is provided on the side of the second baffle 42 near the rotary tiller 41. Multiple protrusions 44 are fixedly mounted on the mounting plate 45. Mounting posts 423 are fixedly provided on both sides of the second baffle 42. The two ends of the mounting plate 45 are sleeved onto the mounting posts 423, and fixing nuts are threaded onto the mounting posts 423. When the surface soil moisture is too high, multiple protrusions 44 can be removed to prevent the soil from becoming too sticky.

[0079] Working principle:

[0080] When in use, the rotary tiller-fertilizer-seeder is moved by a tractor. When the rotary tiller-fertilizer-seeder is working, the fertilization mechanism 2 first applies a fixed amount of fertilizer, then the rotary tillage mechanism 4 tills the land and mixes the soil with the fertilizer, and then the seeding mechanism 3 sows the seeds in the fertilized and tilled soil.

[0081] Before use, install the main partition 24, and select one or more secondary partitions 27 to install as needed. The installation position is adjusted according to the fertilization ratio. When the fertilization mechanism 2 is working, the first drive component 22 drives multiple fertilizer rollers 23 to rotate synchronously, transferring the fertilizer from multiple storage areas to the discharge box 212 in a quantitative manner. The discharge box 212 cooperates with the fertilizer tube 213 to directly apply the fertilizer into the soil. When it is necessary to fine-tune the fertilization ratio, for the storage area to be adjusted, the corresponding second drive component 263 drives the moving plate 261 to move, changing the contact length between the fertilizer roller 23 and the fertilizer in the storage area, thereby achieving fine-tuning of the fertilization ratio.

[0082] When the sowing mechanism 3 is working, the drive motor 321 drives the sowing wheel 334 to rotate, the sealing part 351 opens the first outlet 361 and closes the second outlet 362. When the first groove 341 rotates clockwise to the first outlet 361, the seeds in the first groove 341 pass through the waist-shaped groove 353 and fall into the constriction sleeve 39, and are sent to the soil below the sowing machine through the feeding pipe 391.

[0083] When the photoelectric sensor detects that there are no seeds in the first groove 341, the controller 383 controls the electromagnet of the sealing assembly 35 to operate after a preset time, driving the sealing member 351 to open the second outlet 362 and close the first outlet 361. When the second groove 342 corresponding to the first groove 341 rotates clockwise to the second outlet 362, the seeds in the second groove 342 pass through the waist-shaped groove 353 and fall into the constriction sleeve 39, and are sent to the soil below the seeder through the feeding pipe 391. Within a preset time when the second groove 342 rotates past the discharge port 337, the electromagnet of the sealing assembly 35 is controlled to operate, causing the sealing member 351 to open the first outlet 361 and close the second outlet 362.

[0084] When the rotary tillage mechanism 4 is working, the rotary tillage component 41 performs rotary tillage. As the frame 1 moves, it drives the second baffle 42 to move synchronously. The protruding teeth 44 at the bottom of the second baffle 42 create grooves in the tilled soil. The seeds sown by the seeding mechanism 3 fall into the grooves in the soil through the seeding tube, while the soil scattered by the rotary tillage component 41 falls behind the seed landing point after passing through the groove opening 421. As the frame 1 moves, it covers the seeds in the grooves, achieving soil covering.
