Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to a multifunctional seed and fertilizer co-planting machine. Background Technology

[0002] Seed-fertilizer co-application technology is a highly efficient agricultural planting technique that aims to apply seeds and fertilizers to the soil simultaneously in one operation. This technology can improve agricultural production efficiency, save labor costs, and help crops obtain sufficient nutrition in the early stages of growth.

[0003] In existing technologies, for seeds that support seed-fertilizer mixing, the fertilizer and seeds are usually mixed together in one go and loaded into a hopper before planting, thus completing the fertilization operation simultaneously with sowing. However, because it is difficult to accurately control the amount of seeds and fertilizer to be mixed, if too much seeds and fertilizer are mixed at once, the remaining seeds and fertilizer cannot be used after the operation and are not convenient to separate and store, resulting in waste of seeds and fertilizer. On the other hand, for seeds that do not support seed-fertilizer mixing, existing machines usually sow seeds and fertilizer separately, with the fertilizer applied near the seeds. However, existing seed-fertilizer co-sowing machines cannot switch between mixed and separate sowing functions according to agronomic needs. Therefore, a multi-functional seed-fertilizer co-sowing machine is needed to meet the diverse needs of agricultural production. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In this invention, seeds and fertilizer are first poured into the seed box and fertilizer box respectively, or one of them can be poured in separately for sowing or fertilization. Then, the operator moves the frame in the sowing area, causing the furrow opener to create sowing furrows in the soil. Seeds and fertilizer are continuously transported to the mixing bin. The driving wheels continuously rotate, causing two baffles to open and close repeatedly. When the baffles are closed, the seeds and fertilizer accumulate together; when the baffles are open, the seeds and fertilizer fall together into the furrows through the mixing discharge pipe, achieving simultaneous mixing of sowing and fertilization, while ensuring uniform spacing between each drop. If the sowing and fertilization spacing needs adjustment, the sowing and fertilization speed can be adjusted by replacing the second drive wheel and second drive belt of different sizes, thereby adjusting the sowing and fertilization spacing. This invention allows seeds and fertilizer to be mixed during operation, eliminating the need for pre-mixing. After operation, any remaining seeds and fertilizer can be removed and stored separately, reducing waste of fertilizer and seeds.

[0017] (2) By rotating the knob at the corresponding position, the size of the internal space of the discharge wheel in the discharge device can be adjusted, and the amount of seeds and fertilizer falling into the two discharge wheels can be changed so as to adjust the delivery amount and mixing ratio of seeds and fertilizer according to the operation requirements. During the movement of the frame, the mixing rod can stir the fertilizer and seeds on the baffle so that the two are fully mixed. The evenly mixed seeds and fertilizer can be evenly distributed in the soil to provide a balanced supply of nutrients for crop growth.

[0018] (3) For seeds and fertilizers that do not support mixing, the orientation of the two guide tubes can be changed by rotating the bidirectional adjusting screw so that they are aligned with the diversion hole. At this time, the falling fertilizer and seeds will fall out through the two single material discharge tubes respectively. By designing the outlet positions of the two single material discharge tubes at intervals, the seeds and fertilizers can be sown separately to avoid fertilizers damaging the seeds, thereby meeting the needs of different sowing and fertilization operations.

[0040] 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.

[0041] Example 1: Please refer to Figure 1-12 This invention provides a technical solution: a multifunctional seed and fertilizer co-planting machine, comprising a frame 1; a lifting screw 101 is threadedly installed on the frame 1, and a furrow opener 102 is rotatably installed at one end of the lifting screw 101; two guide slides 103 are installed on the furrow opener 102, and both guide slides 103 are slidably installed on the frame 1; a seed box 2 and a fertilizer box 3 are installed on the frame 1; a feeder 4 is installed on both the seed box 2 and the fertilizer box 3; the seed box 2 and the fertilizer box 3 are respectively connected to the two feeders 4; a feeding structure is installed on each of the two feeders 4; an adjustment structure is installed on the feeding structure; a guide 5 is installed on each of the two feeders 4; a guide structure is installed on each of the two guides 5; the two guides 5 are respectively... The machine is connected to two feeders 4. A mixing bin 6 is installed on the frame 1. The mixing bin 6 is located below the two feeders 5. A sealing structure is installed on the mixing bin 6. A mixing rod 7 is rotatably installed on the inner wall of the mixing bin 6. A mixing structure is installed on the mixing rod 7. A bidirectional adjusting screw 8 is rotatably installed on the frame 1. A switching structure is installed on the bidirectional adjusting screw 8. When in use, the seeds and fertilizer are poured into the seed box 2 and fertilizer box 3 respectively. While pushing the frame 1, the materials can fall into the corresponding feeding structures respectively. Then, under the guidance of the guiding structure, they enter the mixing bin 6 and are blocked by the sealing structure. During the process, the mixing structure can mix the seeds and fertilizer. Finally, the sealing structure unfolds and the mixed materials fall out through the feeding structure.

[0042] Furthermore, the feeding structure includes two annular drive wheels 401, which are rotatably mounted on both sides of the feeder 4. Threaded sleeves 402 are slidably mounted on the inner walls of both annular drive wheels 401. The same positive and negative threaded rod 403 is threaded onto both threaded sleeves 402. A connecting sleeve 404 is rotatably mounted on the positive and negative threaded rod 403, and a feed wheel 405 is mounted on the connecting sleeve 404. The feed wheel 405 connects with the feeder... The inner wall of the feeder 4 is in contact with the material. A first transmission belt 406 is driven and mounted on the annular transmission wheel 401. A first transmission wheel 407 is driven and mounted on the first transmission belt 406. A second transmission wheel 408 is movably mounted on one side of the first transmission wheel 407. A second transmission belt 409 is driven and mounted on the second transmission wheel 408. A third transmission wheel 410 is driven and mounted on the second transmission belt 409. A connecting shaft 411 is mounted on one side of the third transmission wheel 410. A connecting bracket 412 is rotatably mounted on the connecting shaft 411. Mounted on the frame 1, a drive wheel 413 is installed at one end of the connecting shaft 411. As the frame 1 moves, the furrow opener 102 creates seed furrows on the ground, simultaneously causing the drive wheel 413 to contact and roll. The rolling of the drive wheel 413 drives the third transmission wheel 410 to rotate, which in turn drives the second transmission wheel 408 to rotate. The second transmission wheel 408 then drives the first transmission wheel 407 to rotate. The rotation of the first transmission wheel 407 allows it to travel through the first transmission belt... The transmission mechanism of 406 drives two annular transmission wheels 401 to rotate simultaneously. The rotating annular transmission wheels 401 can drive the threaded sleeve rod 402 to rotate, causing the rotating threaded sleeve rod 402 to drive the blocking block 420 to move in a circular motion. By arranging the blocking block 420 and the discharge wheel 405 in a cross configuration, the circularly moving blocking block 420 can drive the discharge wheel 405 to move in a circular motion. While the discharge wheel 405 is moving in a circular motion, it will drive the seeds or fertilizer to move, and finally fall into the guide 5 through the discharge port of the discharger 4.

[0043] Furthermore, a limiting ring 414 is installed on the discharge wheel 405. The limiting ring 414 is rotatably installed on the inner wall of the discharger 4. A limiting ring 421 is rotatably installed on the inner wall of the discharger 4. The limiting ring 421 is installed on one side of the annular transmission wheel 401. Two limiting grooves 415 are designed on the threaded sleeve rod 402. Limiting blocks 416 are slidably installed in both limiting grooves 415. Both limiting blocks 416 are installed on the inner wall of the annular transmission wheel 401. During the circular motion of the discharge wheel 405, it will drive the limiting ring 414 to rotate on the inner wall of the discharger 4, thereby limiting the rotation position of the discharge wheel 405 and preventing it from deviating or loosening.

[0044] Furthermore, the first transmission wheel 407 is designed with multiple threaded holes 417, and multiple mounting bolts 418 are movably installed on one side of the second transmission wheel 408. One end of the mounting bolt 418 passes through the second transmission wheel 408 and is threaded into a corresponding threaded hole 417. By unscrewing the mounting bolt 418 from the second transmission wheel 408 and the first transmission wheel 407, the second transmission wheel 408 can be removed from the first transmission wheel 407.

[0045] Furthermore, the adjustment structure includes two knobs 419, which are respectively installed at both ends of the positive and negative threaded rods 403. Each knob 419 is movably mounted with a limit bolt 422. One end of each limit bolt 422 passes through the two knobs 419 and is threaded onto two threaded sleeves 402. Multiple material blocking blocks 420 are installed on the threaded sleeves 402. The material blocking blocks 420 are movably installed between two corresponding discharge wheels 405. By unscrewing the limit bolts 422 on the knobs 419 on both sides from the threaded sleeves 402, the connection restriction between the positive and negative threaded rods 403 and the threaded sleeves 402 can be released. Then, by pinching the annular transmission wheels 401 on both sides and rotating the knobs 419, the material blocking blocks 420 will move on the positive and negative threaded rods 403 when the knobs 419 are rotated, changing the internal space size of the discharge wheels 405, thereby adjusting the amount of material discharged.

[0046] Furthermore, the guiding structure includes an adjusting cover 501, which is rotatably mounted on the inner wall of the feeder 5. A feed guide pipe 502 is installed on the adjusting cover 501 and is connected to the adjusting cover 501. The feed guide pipe 502 is also connected to the inner wall of the mixing bin 6. Seeds or fertilizers delivered into the feeder 5 will enter the connecting hole 611 through the guidance of the adjusting cover 501 and the feed guide pipe 502.

[0047] Furthermore, the sealing structure includes two rotating shafts 601, both rotatably mounted on the inner wall of the mixing chamber 6. Each rotating shaft 601 is equipped with a baffle 602. The mixing chamber 6 has two connecting holes 611, and two guide pipes 502 are connected to these holes respectively. A linkage rod 603 is mounted at one end of each rotating shaft 601. Each linkage rod 603 has a linkage groove 608, and a linkage shaft 609 is movably mounted within each linkage groove 608. A common slide bar 604 is mounted at one end of each linkage shaft 609. The slide bar 604 is slidably mounted on one side of the mixing chamber 6. A connecting rod 605 is mounted at one end of the slide bar 604, and a stop rod 612 is mounted at the other end of the connecting rod 605. A mounting shaft 607 is mounted on the mixing bin 6. An eccentric wheel 606 is mounted on one end of the mounting shaft 607. The eccentric wheel 606 is in contact with the push rod 612. The mounting shaft 607 is mounted on one side of the first transmission wheel 407. The mounting shaft 607 is rotatably mounted on the mixing bin 6. A mixing discharge pipe 610 is mounted on the bottom side of the mixing bin 6. The mixing discharge pipe 610 is connected to the inner wall of the mixing bin 6. Seeds and fertilizers falling into the mixing bin 6 are blocked by two baffles 602. With the continuous rotation of the first transmission wheel 407, the two baffles 602 can be opened and closed repeatedly. When the two baffles 602 are closed, the seeds and fertilizers can be piled up together. Then the baffles 602 are opened, so that the seeds and fertilizers fall together through the mixing discharge pipe 610 into the trench opened by the furrow opener 102.

[0048] Example 2: As Figure 7-10 To further improve the mixing effect of seeds and fertilizer, a mixing structure is arranged on the mixing rod 7. The mixing structure includes a first bevel gear 701, which is installed at one end of the mixing rod 7. The mixing rod 7 is provided with multiple stirring rods, which are located above the two baffles 602. A second bevel gear 702 is installed on the mounting shaft 607. The second bevel gear 702 meshes with the first bevel gear 701. The rotating mounting shaft 607 can drive the second bevel gear 702 to rotate, thereby causing the rotating second bevel gear 702 to drive the mixing rod 7 to rotate through meshing with the first bevel gear 701. The continuously rotating mixing rod 7 can stir the fertilizer and seeds on the two baffles 602. The remaining features are the same as in Example 1.

[0049] Example 3: As Figure 2-12To enable the machine to adapt to different sowing and fertilization needs and achieve separate sowing of seeds and fertilizers, a switching structure is arranged on the bidirectional adjusting screw 8. The switching structure includes two threaded sliders 801, both of which are threadedly mounted on the bidirectional adjusting screw 8. An adjusting shaft 802 is mounted on one side of each of the two threaded sliders 801, and a mounting rod 803 is movably mounted on each of the two adjusting shafts 802. Movable shafts 804 are mounted on both sides of the two adjusting covers 501. The two movable shafts 804 located on the same side are rotatably mounted on the same feeder 5. The two mounting rods 803 are respectively mounted on one end of the corresponding two movable shafts 804. The inner wall of the mixing bin 6 is designed with two diversion holes. 805, two diversion holes 805 are respectively adapted to two guide pipes 502. Two single material discharge pipes 806 are installed on the bottom side of the mixing bin 6. The two single material discharge pipes 806 are respectively connected to the two diversion holes 805. An adjustment groove 807 is designed on the mounting rod 803. The adjustment shaft 802 is movably installed in the adjustment groove 807. Rotating the bidirectional adjustment screw 8 can drive the orientation of the guide pipe 502 to change so that it is aligned with the diversion hole 805. At this time, the conveyed material can fall out of the single material discharge pipe 806 through the diversion hole 805. By setting the outlet positions of the two single material discharge pipes 806 to be staggered, the contact between the seeds and fertilizer during the sowing process can be avoided. The other features are the same as in Example 1.

[0050] The working principle is as follows: When in use, push the frame 1 to the sowing area, rotate the lifting screw 101, so that the lifting screw 101 rotates on the furrow opener 102. While rotating, the lifting screw 101 moves vertically through the threaded engagement with the frame 1, so that the vertically moving lifting screw 101 drives the furrow opener 102 to descend. The descending furrow opener 102 will drive the guide slide 103 to slide on the frame 1, thereby restricting the movement direction of the furrow opener 102. By adjusting the height of the furrow opener 102, the depth of sowing and fertilization can be changed. The seeds are then poured into the seed box 2, and the fertilizer into the fertilizer box 3. The seeds and fertilizer fall into the feeder 4 through the outlets of the seed box 2 and fertilizer box 3 respectively, and are located inside the two adjacent feed rollers 405. At this time, the frame 1 is pushed. As the frame 1 moves, the furrow opener 102 opens a planting furrow on the ground, simultaneously causing the drive wheel 413 to contact the ground and roll. During the rolling of the drive wheel 413, it drives the third transmission wheel 410 to rotate via the connecting shaft 411. When the third transmission wheel 410 rotates, it drives the second transmission wheel 408 to rotate through the transmission engagement with the second transmission belt 409. Wheel 408 drives the first transmission wheel 407 to rotate via mounting bolt 418. When the first transmission wheel 407 rotates, it drives two annular transmission wheels 401 to rotate simultaneously through the transmission engagement with the first transmission belt 406. The rotating annular transmission wheels 401 drive the limiting ring 421 to rotate on the feeder 4, thus preventing the annular transmission wheels 401 from disengaging from the feeder 4 during rotation. The continuously rotating annular transmission wheels 401 can drive the threaded sleeve rod 402 to rotate through the engagement of the limiting groove 415 and the limiting block 416, so that the rotating threaded sleeve rod 402, through the engagement with the limiting bolt 422, drives the threaded sleeve rod 402 to rotate. The knob 419 and the threaded rod 403 rotate, and the rotating threaded sleeve 402 drives the blocking block 420 to rotate. By arranging the blocking block 420 and the discharge wheel 405 in a cross configuration, the rotating blocking block 420 drives the discharge wheel 405 to rotate. During this process, the discharge wheel 405 drives the connecting sleeve 404 to rotate. As the discharge wheel 405 rotates, it also moves the seeds or fertilizer downwards, eventually falling into the guide 5 through the discharge port of the discharger 4. Thus, the continuous rotation of the discharge wheel 405 enables the continuous conveying of seeds or fertilizer. Seeds or fertilizers fed into the feeder 5 are guided by the adjusting cover 501 and the feed tube 502 into the connecting hole 611. After passing through the connecting hole 611, they fall into the mixing bin 6. The seeds and fertilizers falling into the mixing bin 6 are simultaneously blocked by two baffles 602. At the same time, the rotation of the first transmission wheel 407 drives the mounting shaft 607 to rotate, which in turn drives the eccentric wheel 606 to rotate. During the continuous rotation of the eccentric wheel 606, its flat surface contacts the abutment rod 612. At this time, the restriction on the connecting rod 605 and the two baffles 602 is released, causing the baffles 602 to flip.The flipping baffle 602 drives the rotating shaft 601 to rotate, causing the rotating shaft 601 to drive the linkage rod 603 to flip. The flipping linkage rod 603, through the cooperation of the linkage groove 608 and the linkage shaft 609, drives the slide bar 604 to descend. The descending slide bar 604 drives the connecting rod 605 to descend, causing the connecting rod 605 to drive the abutment rod 612 to continue to contact the curved surface of the eccentric wheel 606. The continuously rotating eccentric wheel 606 will push the abutment rod 612 back up, at which point the two baffles 602 can be closed again. Thus, under the continuous rotation of the first transmission wheel 407, the two baffles 602 can reciprocate opening and closing. In the closed state of the two baffles 602, the seeds and fertilizer can be piled together. Afterwards, the baffles 602 are opened, allowing the seeds and fertilizer to fall together through the mixing discharge pipe 610 into the furrow opened by the furrow opener 102, completing the sowing and fertilization operation.

[0051] By unscrewing the limiting bolts 422 on the knobs 419 on both sides from the threaded sleeve 402, the connection restriction between the forward and reverse threaded rod 403 and the threaded sleeve 402 can be released. Then, pinch the annular transmission wheels 401 on both sides and rotate the knobs 419. When the knobs 419 rotate, they will drive the forward and reverse threaded rod 403 to rotate on the connecting sleeve 404. The threaded sleeve 402 will be restricted by the limiting block 416 and the limiting slide groove 415 and thus cannot rotate with the forward and reverse threaded rod 403. At the same time, the connecting sleeve 404 will be restricted by the discharge wheel 405 and the blocking block 420 and thus cannot rotate with the forward and reverse threaded rod. Rotating rod 403 causes the rotating positive and negative threaded rod 403 to slide horizontally through the threaded engagement with threaded sleeve rod 402. The sliding threaded sleeve rod 402 can slide on two limit blocks 416 through two limit grooves 415 respectively. At the same time, the sliding threaded sleeve rod 402 will drive the material blocking block 420 to move between the two discharge wheels 405, further reducing the internal space of the two discharge wheels 405, so as to adjust the amount of material dropped. After adjustment, the limit bolt 422 is re-passed through the knob 419 and screwed onto the threaded sleeve rod 402 to fix it again. By unscrewing the mounting bolts 418 from the second drive wheel 408 and the first drive wheel 407, the second drive wheel 408 can be removed from the first drive wheel 407. At this time, a second drive wheel 408 of a different size can be replaced according to the required material drop distance and installed on the first drive wheel 407. At the same time, a second drive belt 409 of the corresponding size can be replaced. By installing second drive wheels 408 and second drive belts 409 of different sizes, the rotational speed of the first drive wheel 407 can be changed when the drive wheel 413 moves under the same operation, thereby adjusting the material drop distance.

[0052] While the seeds and fertilizer are piled on the baffle 602, the continuously rotating mounting shaft 607 can drive the second bevel gear 702 to rotate, which in turn causes the rotating second bevel gear 702 to drive the mixing rod 7 to rotate through meshing with the first bevel gear 701. The continuously rotating mixing rod 7 can stir the fertilizer and seeds on the two baffles 602, so that the seeds and fertilizer are evenly mixed.

[0053] Rotating the bidirectional adjusting screw 8 allows it to rotate on the frame 1. The rotating bidirectional adjusting screw 8, through its threaded engagement with the two threaded sliders 801, causes the two threaded sliders 801 to move closer to each other. This causes the moving threaded sliders 801 to move the adjusting shaft 802 within the adjusting groove 807. Simultaneously, the moving adjusting shaft 802 presses against the adjusting groove 807 and rotates the mounting rod 803. The rotating mounting rod 803 drives the movable shaft 804 to rotate, which in turn causes the adjusting cover 501 to flip. The flipped adjusting cover 501 changes the orientation of the guide pipe 502, aligning it with the diversion hole 805. At this time, the conveyed material and fertilizer can fall out through the diversion hole 805 from the single material discharge pipe 806. By staggering the outlet positions of the two single material discharge pipes 806, contact between the seeds and fertilizer during the sowing process can be avoided.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
