Description

Technical Field

[0008] ,

[0001] The present invention belongs to the technical field of seeders, and particularly relates to a single-row fertilization and efficiency-enhancing seeder for triangular planting. Background Art

[0002] Triangular staggered seeding is an advanced planting mode widely promoted in recent years. This mode usually adopts wide and narrow row configurations, and adjacent two rows of crops are sown in a triangular staggered manner. This layout is beneficial to improving the ventilation and light transmission conditions in the field, increasing the planting density, and thus laying a population structure foundation for high crop yields.

[0003] Fertilization is a key link affecting crop yields and fertilizer use efficiency. At present, the fertilization devices supporting triangular seeders mostly adopt the technology of simultaneous sowing of seeds and fertilizers. A common method is to parallelly arrange two basal fertilizer fertilization furrow openers in front of the seeding monomer, and open furrows and apply fertilizers in front of or on the side and below of the seedbed to form two parallel basal fertilizer bands.

[0004] However, in actual production applications, the above traditional double-fertilizer-band mode has obvious drawbacks. For example, the two fertilization bands disperse fertilizers over a large area on both sides of the crop rows. In the early growth stage of crops, the roots have not fully expanded, and it is difficult to effectively absorb and utilize all the nutrients in the two fertilization bands, resulting in some fertilizers being left idle outside the effective root absorption area. At the same time, in areas where irrigation technologies such as drip irrigation are often used, in the traditional fertilization method, the positional relationship between the fertilizer band and the drip irrigation band is often not optimized. The matching degree between the water infiltration range and the fertilizer concentrated distribution area is not high, and it is difficult to efficiently deliver nutrients to the dense root area of crops through irrigation water, affecting the exertion of the synergistic effect of integrated water and fertilizer management. Summary of the Invention

Detailed Implementation

[0030] 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.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the prior art, there is a triangular seeder, including a frame, a fertilization component, and a transmission component. The fertilization component and the transmission component are both mounted on the frame. The input end of the transmission component is connected to the ground wheel, and the output end is connected to the fertilization component to drive the fertilization component to perform fertilization. The fertilization component includes a fertilizer box, and multiple fertilizer dispensing boxes are set at the bottom of the fertilizer box. The fertilizer dispensing boxes are connected to the fertilizer box, and a rotating body is set inside the fertilizer dispensing box. The rotating body is connected to the transmission component, so that the rotating body rotates around its axis. The rotating surface of the rotating body is located between the inlet and outlet of the fertilizer dispensing box. The rotating surface is provided with a first fertilizer trough and a second fertilizer trough, and the two have different volumes. The positions of the first fertilizer trough and the second fertilizer trough in the fertilizer dispensing box are adjustable.

[0033] Multiple rotating bodies are connected by a fertilizer shaft, which is coaxial with the fertilizer shaft. The fertilizer shaft is connected to the output end of the transmission component. The rotating bodies and the fertilizer shaft remain relatively fixed.

[0034] One end of the fertilizer shaft is connected to the fertilizer box, and the other end is equipped with an adjustment device that drives the fertilizer shaft to move linearly along its axis.

[0035] It also includes a seeding component, the output end of which is connected to the seeding component to drive the seeding component to sow seeds; the fertilization component works synchronously with the seeding component.

[0036] The transmission assembly includes a first transmission component, a second transmission component, a third transmission component, and a fourth transmission component. The input end of the first transmission component is connected to the ground wheel, and the output end of the first transmission component is connected to the power shaft. The power shaft is connected to the sowing shaft through a gearbox. The sowing shaft is connected to the sowing assembly through the second and third transmission components. The sowing shaft is connected to the fertilizer shaft through the fourth transmission component.

[0037] The input end of the second transmission component is connected to the power shaft, and the output end is provided with a first engagement tooth; the input end of the third transmission component is provided with a second engagement tooth, and the first engagement tooth and the second engagement tooth are connected in a one-way meshing connection; the output end of the third transmission component is connected to the seeding assembly.

[0038] The sowing assembly includes a sowing bracket, a seed storage box at the top of the sowing bracket, a sowing tray near the ground, and the sowing tray is connected to the seed storage box. The sowing tray has a seed drop opening and is connected to the output end of the third transmission component to drive the sowing tray to rotate.

[0039] There are multiple sets of seeding components, and the initial position of the seed drop opening of the seeding tray of adjacent seeding components is different.

[0040] An indicator device is provided at the corresponding position of the seeding component. The indicator device is used to indicate the initial position of the seed drop opening.

[0041] The seeding assembly is connected to the press wheel assembly. In the direction of travel of the seeder, the seeding assembly and the press wheel assembly are arranged one in front of the other, with the seeding assembly located in front of the press wheel assembly.

[0042] In the above-described triangular seeder, the rotating ground wheel transmits power to the fertilization component, enabling the seeder to apply fertilizer. Fertilizer falls from the fertilizer bin into the fertilizer outlet box. The rotating body, driven by the transmission component, prevents blockage during fertilizer descent, accelerates the descent, and improves fertilization efficiency. The first and second fertilizer troughs buffer the falling fertilizer. Simultaneously, due to the rotation of the rotating body, the fertilizer is ejected by centrifugal force, preventing it from remaining in the first and second fertilizer troughs for extended periods. By adjusting the positions of the first and second fertilizer troughs in the fertilizer outlet box, the volume ratio of the two troughs along the fertilizer descent path changes, thus altering the fertilizer buffering amount. Since the seeder moves forward, the amount of fertilizer falling also changes with the buffering amount. By controlling the positions of the first and second fertilizer troughs in the fertilizer outlet box, the amount of fertilizer applied can be controlled.

[0043] Reference Figures 1-6 This invention provides a single-ridge fertilization and efficiency-enhancing seeder for triangular planting, including a frame 1, and further comprising:

[0044] The fertilization assembly includes a fertilizer box 3 located at the front end of the frame 1 and several fertilizer spreading mechanisms. The fertilizer spreading mechanisms are used to spread the fertilizer in the fertilizer box 3 into the soil at a set depth.

[0045] The sowing assembly includes a seed box 5 located in the middle of the frame 1 and several seed sowing mechanisms. The seed sowing mechanisms are connected to the bottom of the seed box 5. Each seed sowing mechanism is equipped with a seed output adjustment unit, which is used to adjust the number of seeds sown. The bottom of each seed sowing mechanism is connected to a sowing component for sowing seeds into the soil. The spacing between two adjacent sowing components is provided with a wide spacing and a narrow spacing, and the wide spacing and the narrow spacing are set alternately. Several fertilizer sowing mechanisms are set in correspondence with several narrow spacings.

[0046] The drip irrigation tape laying assembly includes several drip irrigation tape fixing wheels 15 and several drip irrigation tape laying mechanisms located at the rear of the frame 1. The drip irrigation tape laying mechanisms are respectively located behind several fertilizer spreading mechanisms.

[0047] Several seed distributing mechanisms are arranged at alternating wide and narrow intervals, resulting in wide and narrow rows of seed strips after sowing. The main function of the fertilizer spreading mechanism is to spread fertilizer in the soil while positioning the fertilizer strip in the middle of the narrow rows. The main function of the drip irrigation tape laying mechanism is to lay the irrigation tape above the fertilizer strip, allowing drip irrigation water to quickly dissolve the fertilizer and deliver it to the roots on both sides. The main function of the seed quantity adjustment unit is to adjust the number of seeds sown in a single operation. Overall, the seeder of this invention highly integrates the triangular planting pattern and drip irrigation technology, solving the core problems of dispersed fertilizer distribution, easy loss, and low coupling efficiency with water in existing sowing technologies. It balances the accuracy of fertilizer application location and the effectiveness of water and fertilizer synergy, making it suitable for planting crops such as corn that require improved fertilizer utilization.

[0048] In a further optimized design, the seed distributing mechanism includes a second distributing box 6 fixedly connected to the frame 1. A seed distributing wheel 20 is rotatably connected inside the second distributing box 6. Several seed grooves 21 are evenly spaced on the side wall of the seed distributing wheel 20. A feeding channel 23 is provided at the top of the second distributing box 6. The top of the feeding channel 23 is connected to the seed box 5, and the bottom of the feeding channel 23 is connected to the several seed grooves 21 located above. A discharging channel 24 is provided at the bottom of the second distributing box 6. The top of the discharging channel 24 is connected to the several seed grooves 21 located below, and the bottom of the discharging channel 24 is connected to the spreading component. A seed discharging adjustment unit is located between the seed distributing wheel 20 and the second distributing box 6. Several seed distributing wheels 20 in several second distributing boxes 6 are connected by a drive mechanism through the seed discharging adjustment unit.

[0049] like Figure 1 and Figure 4As shown, in this embodiment, two sets of seed boxes 5 are provided, and the bottom of each seed box 5 is connected to two sets of second distribution boxes 6. During use, the seed distribution wheel 20 rotates counterclockwise, and the seeds come into contact with the seed distribution wheel 20 through the feeding channel 23. Some seeds fall into the seed trough 21 with the opening facing upward and move downward with the rotation of the seed distribution wheel 20. When the seed trough 21 is open downward and in the discharge channel 24, the seeds in the seed trough 21 fall into the spreading component in sequence.

[0050] The seed output adjustment unit further optimizes the scheme by including an adjustment wheel 29 rotatably connected in the second distribution box 6. Several insert plates 22 are fixedly connected at equal intervals along the axis of the seed distribution wheel 20 on the side wall of the adjustment wheel 29 near the seed distribution wheel 20. The insert plates 22 pass through the side wall of the seed trough 21 and are slidably connected in the seed trough 21.

[0051] Several adjusting wheels 29 in the second material distribution box 6 are coaxially fixedly connected by a transmission rod 36. The transmission rod 36 is used to drive the adjusting wheels 29 to rotate. Several seeding wheels 20 are rotatably sleeved on the transmission rod 36. A position adjusting component is provided between the transmission rod 36 and a second material distribution box 6. The position adjusting component is used to adjust the axial clearance between the adjusting wheel 29 and the seeding wheel 20, thereby adjusting the depth of the insert plate 22 inserted into the seed groove 21, and thus adjusting the volume of the seed groove 21.

[0052] like Figure 5 As shown, to achieve synchronous adjustment of the seed troughs 21 on each seeding wheel 20, the adjusting wheel 29 needs to be located on the same side of the seeding wheel 20. In this embodiment, a total of four sets of second distribution boxes 6 are provided. When it is necessary to increase the volume of the various troughs 21 on the four sets of seeding wheels 20, the transmission rod 36 can be moved to the left by the position adjusting component. At this time, the transmission rod 36 drives the four sets of adjusting wheels 29 to move synchronously to the left. At the same time, the adjusting wheel 29 drives the insert plate 22 to move to the left, thereby increasing the volume of the seed trough 21 by increasing the axial length of the seed trough 21.

[0053] The scheme is further optimized. The position adjustment component includes a turntable 30 coaxially fixedly connected to the transmission rod 36 and several connecting rods 34 fixedly connected to a second material distribution box 6. The several connecting rods 34 are slidably connected to a limit frame 33 along the axial direction of the transmission rod 36. The turntable 30 is rotatably connected in the prime number limit frame 33. The ends of the connecting rods 34 are threadedly connected to two sets of fixing nuts 35. The limit frame 33 abuts between the two fixing nuts 35.

[0054] like Figure 5 and Figure 6As shown, when it is necessary to move the transmission rod 36 to the left, the fixing nuts 35 can be loosened, and the limiting bracket 33 can be moved to the left along the connecting rod 34 by pulling it. The turntable 30 can then be pulled to move the transmission rod 36 to the left. After the position is adjusted to the correct position, the fixing nuts 35 on both sides can be tightened to fix the position of the limiting bracket 33, thereby fixing the axial position of the transmission rod 36.

[0055] Further optimize the plan, such as Figure 5 As shown, in this embodiment, a sprocket 31 is connected to the middle of the transmission rod 36 via a spline drive, and two sets of limiting plates 32 are fixedly connected to the frame 1. The two limiting plates 32 are located on both sides of the sprocket 31, which can prevent the sprocket 31 from moving excessively along its axial direction when the transmission rod 36 moves left and right.

[0056] In a further optimized design, a transmission box 19 is fixedly connected to the front end of the frame 1. The traction device is connected to the input end of the transmission box 19. A drive sprocket (not shown in the figure) is provided at the output end of the transmission box 19. The drive sprocket is connected to the sprocket 31 via a chain. When the transmission box 19 is running, the sprocket 31 drives the transmission rod 36 to rotate. The transmission rod 36 drives four sets of adjusting wheels 29 to rotate. The adjusting wheels 29 push the seed trough 21 through several insert plates 22 to achieve synchronous rotation of the seeding wheel 20. The turntable 30 can rotate within the limiting frame 33.

[0057] The scheme is further optimized. The spreading component includes a drop pipe 7 fixedly connected to the bottom of the second distribution box 6. The drop pipe 7 is connected to the discharge channel 24. A rear trenching knife 8 is fixedly connected to the bottom of the drop pipe 7. The rear trenching knife 8 is used to make the bottom of the drop pipe 7 at a set depth in the soil.

[0058] like Figure 1 As shown, during use, the feed pipe 7 causes the rear ditching blade 8 to insert into the soil. As the frame 1 moves forward, the rear ditching blade 8 digs a trench on the soil surface and causes the seeds to fall into the trench.

[0059] Further optimizing the scheme, the fertilizer spreading mechanism includes a first distribution box 4 fixedly connected to the bottom of the fertilizer box 3. A distribution wheel 25 is rotatably connected inside the first distribution box 4. Several baffles 26 are fixedly connected at equal intervals on the side wall of the distribution wheel 25. A receiving groove is formed between two adjacent baffles 26. A fertilizer inlet channel 27 is provided inside the first distribution box 4. The top of the fertilizer inlet channel 27 is connected to the fertilizer box 3. The bottom of the fertilizer inlet channel 27 is correspondingly set to the receiving groove located above. A fertilizer outlet channel 28 is also provided inside the first distribution box 4. The top of the fertilizer outlet channel 28 is connected to the receiving groove located below. The bottom of the fertilizer outlet channel 28 is connected to a trenching fertilizer applicator through a hose.

[0060] To further optimize the design, this embodiment also includes a second transmission rod that passes through and is connected to several material distribution wheels 25. A second sprocket is fixedly mounted on the second transmission rod, and the second sprocket is connected to the drive sprocket via a chain drive. When the transmission box 19 is running, the second sprocket can drive the second transmission rod to rotate, thereby rotating the material distribution wheels 25.

[0061] like Figure 1 and Figure 3 As shown, in this embodiment, as the distributing wheel 25 rotates, the fertilizer in the fertilizer box 3 falls into an upward-opening receiving trough through the fertilizer inlet channel 27, and as the distributing wheel 25 rotates, the fertilizer that moves to the bottom of the receiving trough enters the hose through the fertilizer outlet channel 28 and then enters the trenching fertilizer applicator.

[0062] Further optimization of the scheme: the trenching and fertilization component includes a front trenching blade 2, which is fixedly connected to the bottom front end of the frame 1. The bottom of the front trenching blade 2 is provided with a groove, and the hose is connected to the groove.

[0063] like Figure 1 As shown, the front trenching blade 2 is connected to the lower front end of the frame 1 via a support rod. During operation, the front trenching blade 2 is inserted into the soil. As the frame 1 moves forward, the front trenching blade 2 digs trenches on the soil surface and allows the seeds to fall into the trenches in the soil through the tube and the trench.

[0064] In a further optimized design, the tail end of the frame 1 is fixedly connected to several brackets 14, and several drip irrigation tape fixing wheels 15 are detachably and rotatably connected to the brackets 14.

[0065] The solution is further optimized. The drip irrigation tape laying mechanism includes a guide pipe 16 fixedly connected to the tail of the frame 1. The drip irrigation tape passes through the guide pipe 16 and is laid on the soil surface. Two sets of second covering wheels 17 are rotatably connected to the bottom sides of the guide pipe 16. The second covering wheels 17 are used to bury the drip irrigation tape shallowly in the soil surface.

[0066] like Figure 1 As shown, the rolled drip irrigation tape is fixed to the drip irrigation tape fixing wheel 15, and the tail end is passed through the guide tube 16, extending from the bottom and fixed in the soil. When the frame 1 moves, the drip irrigation tape fixing wheel 15 rotates automatically, so that the drip irrigation tape is laid on the soil surface in sequence, covering the fertilizer layer. The main function of the second soil covering wheel 17 is to cover the surface of the drip irrigation tape with soil, realizing the shallow burial of the drip irrigation tape.

[0067] In this embodiment, by controlling the depth of the front furrow cutter 2, the fertilizer is controlled to be between 10cm and 15cm below the drip irrigation tape.

[0068] In a further optimized design, several vertical rods 10 are fixedly connected vertically inside the frame 1. The vertical rods 10 are located behind several material drop pipes 7. Two sets of first covering wheels 11 are rotatably connected to the bottom of the vertical rods 10. The first covering wheels 11 are used to cover the soil in the trenches excavated by the rearward trenching cutter 8.

[0069] like Figure 1 As shown, the main function of the first covering wheel 11 is to cover the soil on both sides of the trench dug by the rear furrow cutter 8 back into the trench after sowing, thus burying the seeds.

[0070] In a further optimized design, a fixed rod 9 is horizontally fixedly connected inside the frame 1, and several vertical rods 10 are fixedly connected to the fixed rod 9.

[0071] Further optimization of the scheme also includes several rolling rollers 13, which are located on the rear side of several vertical rods 10. One end of several swing rods 12 is hinged inside the frame 1. The rolling rollers 13 are rotatably connected to the other end of the swing rods 12. A spring is abutting between the swing rods 12 and the frame 1. The spring is used to keep the rolling rollers 13 in close contact with the ground.

[0072] like Figure 1 and Figure 2 As shown, after the first covering wheel 11 covers the soil in the trench, the rolling wheel 13 immediately compacts the soil to ensure good sowing results.

[0073] In a further optimized design, a connecting frame 18 is fixedly connected to the front end of the frame 1. The main function of the connecting frame 18 is to connect the frame 1 to the traction equipment.

[0074] In a further optimized design, a load-bearing wheel (not shown in the figure) is rotatably connected to the bottom of the tail end of the frame 1. The main function of the load-bearing wheel is to help maintain the stable movement of the frame 1.
