A smart agricultural planter

Abstract

This invention discloses a smart agricultural planter, relating to the field of agricultural planting machinery technology. When the driver operates the tractor to adjust the general direction or turn around, the seeding attachment is automatically lifted off the ground. At this time, the independent walking wheels of the seeding attachment are de-energized, thus disconnecting the seeding operation of the seeding rollers in the seeding attachment. Even though the negative pressure material distribution mechanism is still in the material suction state, the seeding attachment no longer continues a series of operations such as furrowing, seeding, soil covering, and compaction. This achieves the effect of disconnecting the seeding operation when turning, which is more in line with actual production. Furthermore, the furrowing, soil covering, and compaction operations stop simultaneously to prevent damage to the surrounding field during turning, further ensuring the uniformity and efficiency of the seeding operation. This eliminates the adverse effects caused by the fact that the power source does not disconnect when the tractor is turning to adjust the machine position and working area, and the seeding work continues.

Description

Technical Field

[0001] This invention relates to the field of agricultural planting machinery technology, specifically to a smart agricultural planting seeder. Background Technology

[0002] A seed drill is a type of planting machinery that uses crop seeds as the object of sowing. It can complete a series of actions such as furrowing, seeding, soil covering, and compaction during the sowing process, thereby greatly improving the planting efficiency of crops such as corn, peanuts, and beans, and effectively reducing the amount and intensity of labor for farmers when carrying out planting operations.

[0003] For example, a seeder for agricultural planting, disclosed in CN119302087A, is configured with a circular shell, a rotating shaft, a motor, conveying blades, and mounting components. Fertilizer or seeds enter the circular shell through the feed pipe and are temporarily stored between two adjacent conveying blades. As the conveying blades rotate forward, they are discharged from the discharge pipe, achieving the effects of fertilization and sowing. At the same time, by configuring a first mounting sleeve, a second mounting sleeve, a sealing plate, a connecting block, a connecting sleeve, a protrusion, a spiral groove, and an operating shaft, the position of the conveying blades is first adjusted and fixed, and then the sealing plate rotates to open the notch of the conveying blades, allowing fertilizer and seeds to flow continuously and be smoothly discharged from the recovery pipe, effectively improving the efficiency of the entire recovery operation.

[0004] As agricultural planting becomes increasingly automated and intelligent, the functions and operational efficiency of seeders have been continuously improved and perfected. However, most automated seeders face a common problem in actual production: seeders are often connected to tractor units via a towing mechanism. In large-scale, standardized field production, most seeders generally follow the tractor unit, using their own walking force as a power source or directly connecting to the seeder through the tractor unit's drive force. Regardless of the power source method, the following issue arises: the power source remains connected when the tractor unit is turning to adjust its position or work area, and the sowing work continues.

[0005] Tractor-driven seeders often operate in a straight line. After reaching the end of the line, they need to turn around to continue the next row of seeding. During the turning process, whether the tractor-driven seeder uses the tractor as its output power or its own walking as its power source, it will continue to maintain its working posture. This means that a series of operations such as furrowing, seeding, covering with soil, and compaction will still be carried out. This leads to a chaotic seeding process near the edge of the field. In addition, when turning around, the seeder often uses the field ridges, which inevitably causes a certain degree of tilting. This forces the seeder to walk on a slightly higher ridge and continue the series of operations such as furrowing, seeding, covering with soil, and compaction at the intersection of the ridges. This further exacerbates the chaos in the seeding of the field edge area when turning around and causes some crop seeds to be wasted.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing smart agriculture seeders. Summary of the Invention

[0007] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the invention aims to provide a smart agricultural planter that addresses the aforementioned issue of traction machines operating in a linear fashion. After reaching the end of the line, the machine needs to turn around to continue the next linear planting operation. During this turning process, whether the planter uses the traction machine as its power source or its own movement, it continues to maintain its working posture. This means that a series of steps, such as furrowing, seeding, covering, and compaction, are still being performed. This leads to chaotic planting near the field edge. Furthermore, when turning, the machine often uses field ridges, inevitably causing some tilting. This forces the planter to move to a slightly higher ridge and continue furrowing, seeding, covering, and compaction at the ridge intersection, further exacerbating the chaos in the field edge area during turning and resulting in wasted crop seeds.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a smart agricultural planter, comprising a tractor, a seeding attachment pulled by the tractor, and a steering assist system installed at the front end of the tractor, and further comprising a support plate fixed to the bottom of the tractor for support, a driven shaft rotatably mounted on the upper surface of the support plate and driven to rotate by the steering assist system, and a paddle fixed to the outer wall of the driven shaft for lifting the seeding attachment when the tractor makes a large turn. A pin shaft is provided between the seeding attachment and the tractor, which can serve as a rotation center for the seeding attachment to rotate, and a driven rotating plate is fixed to the outer wall of the driven shaft, which can adaptively swing with the turn of the tractor.

[0009] Preferably, the power output shaft of the traction machine is connected to the power input shaft of the sowing device through a multi-stage transmission rod, and a telescopic rod that can adaptively retract as the sowing device rotates is installed at the center of the multi-stage transmission rod.

[0010] Preferably, the front end of the traction machine is symmetrically equipped with guide wheels, and a steering plate is provided between the two guide wheels, and the steering plate is controlled by the steering assist system.

[0011] Preferably, a vertical plate is fixed to the upper surface of the support plate, and an adjusting rod is slidably installed through the interior of the vertical plate. One end of the adjusting rod is fixed with an arc-shaped plate corresponding to the position of the lever, and the other end of the adjusting rod is fixed with a push block.

[0012] Preferably, the surface of the push block away from the support plate is arc-shaped, and a push rod that is fixedly connected to the sowing hanger is attached to the outer surface of the push block, and the contact end between the push rod and the push block is hemispherical.

[0013] Preferably, the paddle is symmetrically arranged on the outer wall of the driven shaft about the central axis of the adjusting rod, and the outer end of the paddle away from the driven shaft is chamfered.

[0014] Preferably, a return spring is wound around the outer wall of the adjusting rod, and one end of the return spring is welded to the side of the support plate, while the other end of the return spring is fixed to the side wall of the push block.

[0015] Preferably, the driven rotating plate has symmetrical first pin grooves at both ends, and a first pin is slidably disposed inside the first pin groove, and the end of the first pin is rotatably connected to a cross plate.

[0016] Preferably, the steering plate has symmetrical second pin grooves at both ends, and a second pin is slidably disposed inside the second pin groove, and the end of the second pin is rotatably connected to the cross plate.

[0017] Preferably, the steering plate has symmetrically provided third pin grooves at both ends, and a third pin is slidably provided inside the third pin groove. The end of the third pin is rotatably connected to one end of a connecting plate, and the other end of the connecting plate is fixed to the outer wall of the guide wheel central shaft.

[0018] The central shaft and the guide wheel are rotatably connected.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] When the driver operates the tractor and controls the guide wheels to steer via the power steering system, the steering plate moves horizontally and exerts a push-pull force on the third pins on both sides through the third pin slots on both sides. This causes the third pins on both sides to push the connecting plates and guide wheels on both sides in the same direction with the same stroke, thereby causing the guide wheels on both sides to rotate at the same angle. At the same time, when the steering plate moves horizontally, it exerts a horizontal push-pull force on the second pins on both sides through the second pin slots on both sides. This causes the second pins on both sides to drive the cross plates on both sides to move in the forward and reverse directions. Similarly, the two cross plates with the same stroke and moving in the forward and reverse directions exert a horizontal push-pull force on the first pin slots symmetrically arranged on both sides of the driven rotating plate through the first pins on both sides. This causes the driven rotating plate to drive the driven rotating plate and the paddle to deflect, and the direction of deflection is consistent with the deflection direction of the guide wheels. When the tractor makes small adjustments to the travel angle to ensure the linearity of the sowing operation, it will not affect the normal sowing operation, which is in line with actual production.

[0021] When the guide wheel deflects significantly, the synchronously rotating paddle contacts and presses the inner arc of the adjusting rod, causing the adjusting rod to slide outward through the vertical plate. Simultaneously, the adjusting rod pushes the push rod via the push block, causing the seeding device to rotate around the pin axis. This lifts the entire seeding device off the ground, and the height off the ground is controlled by the deflection of the guide wheel. Simply put, when the guide wheel deflects significantly—that is, when the operator adjusts the general direction or turns the tractor—the seeding device will be automatically lifted off the ground. At this time, the independent travel wheels of the seeding device will be lifted off the ground. The seeding operation is thus disconnected from the seeding rollers of the seeding device. Even though the negative pressure material distribution mechanism is still in the suction state, the seeding device no longer continues a series of operations such as furrowing, seeding, covering, and compaction. This achieves the effect of disconnecting the seeding operation when turning, which is more in line with actual production. Furthermore, the furrowing, covering, and compaction operations stop simultaneously to prevent damage to the surrounding area of ​​the field during turning, further ensuring the uniformity and efficiency of the seeding operation. This eliminates the adverse effects caused by the fact that the power source does not disconnect when the traction equipment turns to adjust the machine position and working area, and the seeding work continues.

[0032] 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.

[0033] Please see Figures 1 to 9 The present invention provides a technical solution: a smart agricultural planter, including a tractor 1, a seeding attachment 2 tracted by the tractor 1, and a steering assist system 3 installed at the front end of the tractor 1. It also includes a support plate 4 fixed to the bottom of the tractor 1 for support, a driven shaft 5 rotatably mounted on the upper surface of the support plate 4 and driven to rotate by the steering assist system 3, and a paddle 51 fixed to the outer wall of the driven shaft 5 for lifting the seeding attachment 2 when the tractor 1 makes a large turn. A pin 9 is provided between the seeding attachment 2 and the tractor 1, which can serve as the rotation center for the seeding attachment 2 to rotate. A driven rotating plate 6 is fixed to the outer wall of the driven shaft 5, which can adaptively swing with the turn of the tractor 1.

[0034] In specific implementation, in the existing technology, the traction machine 1 is connected to the sowing device 2 by a pin shaft 9. The sowing device 2 has an independent walking mechanism, which serves as the power source for sowing and material distribution. The output power shaft of the traction machine 1 is connected to the negative pressure material distribution mechanism of the sowing device 2 through a multi-stage transmission rod and serves as its power source. In other words, when the traction machine 1 is turning normally, the power of the traction machine 1 will not be disconnected. Therefore, the negative pressure material distribution mechanism of the sowing device 2 will not be disconnected, and the independent walking mechanism of the sowing device 2 is also in operation. Thus, the entire sowing production operation continues during the turning adjustment process of the traction machine 1.

[0035] As a further embodiment of the present invention, the power output shaft of the traction machine 1 is connected to the power input shaft of the sowing device 2 through a multi-stage transmission rod, and a telescopic rod 21 that can adaptively retract as the sowing device 2 rotates is installed at the center of the multi-stage transmission rod.

[0036] In specific implementation, since the power output shaft of the traction machine 1 is connected to the sowing device 2 through a multi-stage transmission rod, the transmission rod in the middle of the multi-stage transmission rod is changed to a telescopic rod 21 with an adaptively adjustable length in this invention. Even when the sowing device 2 is lifted, the adaptive contraction of the telescopic rod 21 can satisfy the rotation of the sowing device 2 around the pin 9, while ensuring that the power output remains connected.

[0037] As a further embodiment of the present invention, guide wheels 31 are symmetrically installed at the front end of the traction machine 1, and a steering plate 8 is provided between the two guide wheels 31, and the steering plate 8 is controlled by the steering assist system 3.

[0038] In practice, the power steering system 3 will drive the steering wheel 8 to move horizontally in sync when the driver turns the steering wheel. Power steering is a common existing technology for vehicles, including mechanical power steering, hydraulic power steering and electric power steering, which will not be elaborated on here.

[0039] As a further embodiment of the present invention, a vertical plate 41 is fixed on the upper surface of the support plate 4, and an adjusting rod 42 is slidably installed through the interior of the vertical plate 41. One end of the adjusting rod 42 is fixed with an arc-shaped plate corresponding to the position of the paddle 51, and the other end of the adjusting rod 42 is fixed with a push block 43.

[0040] In practice, when the guide wheel 31 deflects significantly, the rotation angle of the paddle 51 will also change significantly, contacting and pressing the inner arc of the adjusting rod 42. This causes the adjusting rod 42 to slide outward through the vertical plate 41 and compress the return spring 44. At the same time, the horizontally displaced adjusting rod 42 will push the push rod 45 synchronously through the push block 43. Since the push rod 45 is fixedly connected to the frame of the sowing hanger 2, the pushed push rod 45 will rotate together with the sowing hanger 2 around the pin 9 as the axis, thereby lifting the sowing hanger 2 off the ground. The height off the ground is controlled by the deflection of the guide wheel 31.

[0041] As a further embodiment of the present invention, the side surface of the push block 43 away from the support plate 4 is arc-shaped, and the outer surface of the push block 43 is fitted with a push rod 45 that is fixedly connected to the sowing hanger 2, and the contact end between the push rod 45 and the push block 43 is hemispherical.

[0042] In practice, the hemispherical push rod 45 end is fitted to the arc-shaped outer surface of the push block 43. When the push block 43 presses the push rod 45, it helps to maintain contact stability and prevents contact jumping due to the presence of sharp edges.

[0043] As a further embodiment of the present invention, the paddle 51 is symmetrically arranged on the outer wall of the driven shaft 5 about the central axis of the adjusting rod 42, and the outer end of the paddle 51 away from the driven shaft 5 is chamfered.

[0044] In practice, when the guide wheel 31 deflects significantly, the rotation angle of the paddle 51 will also change significantly, contacting and pressing the inner arc of the adjusting rod 42. At the same time, the two sets of symmetrically arranged paddles 51 can ensure that the driven shaft 5 will contact and press the inner arc of the adjusting rod 42 whether it rotates in the forward or reverse direction. Meanwhile, a certain gap is reserved between the paddle 51 and the inner arc of the adjusting rod 42. The purpose is that when the guide wheel 31 deflects slightly, the paddle 51 will not push the adjusting rod 42. In other words, the driver's fine adjustment of the angle during the sowing operation of the tractor 1 will not cause the sowing device 2 to be lifted. The safety range of the fine adjustment can be determined by the size of the gap reserved between the paddle 51 and the adjusting rod 42.

[0045] As a further embodiment of the present invention, a return spring 44 is wound around the outer wall of the adjusting rod 42, and one end of the return spring 44 is welded to the side of the support plate 4, and the other end of the return spring 44 is fixed to the side wall of the push block 43.

[0046] In practice, the reset spring 44 is only used to reset the auxiliary adjusting rod 42 at the end of the turn, so as to prevent mechanical jerking caused by excessive gap when the adjusting rod 42 is not reset and is squeezed again during the turn.

[0047] As a further embodiment of the present invention, the driven rotating plate 6 has symmetrical first pin grooves 61 at both ends, and a first pin rod 62 is slidably disposed inside the first pin groove 61, and the end of the first pin rod 62 is rotatably connected to a cross plate 7.

[0048] In practice, when the two horizontal pull plates 7 undergo dynamic changes, they will always maintain an attitude with opposite directions of movement and the same stroke. The two horizontal pull plates 7, which always maintain opposite directions of movement and the same stroke, will generate a horizontal pushing and pulling action on the first pin grooves 61 symmetrically arranged on both sides of the driven rotating plate 6 through the first pin rods 62 on both sides. This causes the driven rotating plate 6 to drive the driven rotating plate 6 and the paddle 51 to deflect, and the direction of deflection is consistent with the deflection direction of the guide wheel 31.

[0049] As a further embodiment of the present invention, the two ends of the steering plate 8 are symmetrically provided with second pin grooves 81, and a second pin rod 82 is slidably disposed inside the second pin groove 81, and the end of the second pin rod 82 is rotatably connected to the cross plate 7.

[0050] In practice, when the steering plate 8 moves horizontally, it will generate a horizontal pushing and pulling force in the opposite direction on the second pin rods 82 on both sides through the second pin grooves 81 on both sides (and the pushing and pulling strokes are the same), so that the second pin rods 82 on both sides will drive the horizontal tie plates 7 on both sides to move in the forward and reverse directions.

[0051] As a further embodiment of the present invention, the steering plate 8 is provided with a third pin groove 83 symmetrically at both ends, and a third pin 84 is slidably arranged inside the third pin groove 83. The end of the third pin 84 is rotatably connected to one end of the connecting plate 85, and the other end of the connecting plate 85 is fixed to the outer wall of the central shaft of the guide wheel 31.

[0052] The central shaft and the guide wheel 31 are rotatably connected.

[0053] In practice, the steering plate 8 will push and pull the third pins 84 on both sides in the same direction through the third pin grooves 83 on both sides, so that the third pins 84 on both sides push the connecting plates 85 and guide wheels 31 on both sides in the same direction with the same stroke, thereby causing the guide wheels 31 on both sides to rotate at the same angle, thus achieving steering.

[0054] Working principle: When using this smart agricultural planter, it should first be noted that in the existing technology, the traction machine 1 is connected to the seeding device 2 by a pin shaft 9. The seeding device 2 has an independent walking mechanism, which serves as the power source for seeding and material distribution. The output power shaft of the traction machine 1 is connected to the negative pressure material distribution mechanism of the seeding device 2 through a multi-stage transmission rod and serves as its power source. In other words, when the traction machine 1 is turning normally, the power of the traction machine 1 will not be disconnected. Therefore, the negative pressure material distribution mechanism of the seeding device 2 will not be disconnected, and the independent walking mechanism of the seeding device 2 will also be in operation. Thus, the entire seeding production operation continues during the turning adjustment process of the traction machine 1.

[0055] The specific sowing process of the sowing device 2 in this invention is roughly as follows: The driving power of the traction machine 1 serves as the output source to provide negative pressure power to the negative pressure spreading mechanism. The force generated when the independent rollers of the sowing device 2 move serves as the power source for the rotation of the feeding roller. During normal operation, the negative pressure spreading mechanism generates negative pressure suction from inside the feeding roller and adsorbs the seeds through the fine holes evenly distributed on the surface of the feeding roller. As the feeding roller rotates, the adsorbed seeds will enter the discharge pipe, be scraped off, and fall down the discharge pipe into the spreading trench opened by the furrowing plow below, achieving the effect of adaptive sowing. Finally, the scraper at the end of the sowing device 2 backfills and levels the spreading trench. This is the general working principle of the sowing device 2, which is existing technology and will not be described in detail in this invention.

[0056] When the operator controls the steering wheel 31 via the steering assist system 3, the first step is as follows: Figure 5 and Figure 7 As shown, the power steering system 3 will synchronously drive the steering wheel 8 to move horizontally when the driver turns the steering wheel (power steering is a common existing technology for vehicles, including mechanical power steering, hydraulic power steering, and electric power steering, which will not be elaborated on here). When the steering wheel 8 moves horizontally... Figure 8 When moving horizontally as shown, the steering plate 8 will push and pull the third pins 84 on both sides in the same direction through the third pin grooves 83 on both sides. This causes the third pins 84 on both sides to push the connecting plates 85 and guide wheels 31 on both sides in the same direction with the same stroke, thereby causing the guide wheels 31 on both sides to rotate at the same angle, thus achieving steering.

[0057] At the same time, when the steering plate 8 moves horizontally, it will generate a horizontal push-pull force in the opposite direction on the second pin rods 82 on both sides through the second pin grooves 81 on both sides (and the push-pull stroke is the same), so that the second pin rods 82 on both sides drive the horizontal pull plates 7 on both sides to move in the forward and reverse directions. Similarly, the two horizontal pull plates 7 with the same stroke and moving in the forward and reverse directions will generate a horizontal push-pull force in the forward and reverse directions on the first pin grooves 61 symmetrically arranged on both sides of the driven rotating plate 6 through the first pin rods 62 on both sides. This will cause the driven rotating plate 6 to drive the driven rotating plate 6 and the paddle 51 to deflect, and the direction of deflection is consistent with the deflection direction of the guide wheel 31.

[0058] Immediately afterwards, such as Figure 7 and Figure 9 As shown, a certain gap is reserved between the paddle 51 and the arc-shaped inner end of the adjusting rod 42. This is to prevent the paddle 51 from pushing the adjusting rod 42 when the guide wheel 31 deflects slightly. In other words, the driver's fine-tuning of the angle during the sowing operation of the tractor 1 will not cause the sowing attachment 2 to be lifted. Furthermore, the safety range of the fine-tuning can be determined by the size of the gap between the paddle 51 and the adjusting rod 42. Subsequently, when the guide wheel 31 deflects significantly, the rotation angle of the paddle 51 will also change considerably, contacting and pressing the arc-shaped inner end of the adjusting rod 42, thereby... The adjusting rod 42 slides outward through the vertical plate 41 and compresses the return spring 44. At the same time, the horizontally displaced adjusting rod 42 pushes the push rod 45 synchronously through the push block 43. Since the push rod 45 is fixedly connected to the frame of the sowing device 2, the pushed push rod 45, together with the sowing device 2, rotates around the pin 9 as the axis, thereby lifting the sowing device 2 off the ground. The height off the ground is controlled by the deflection of the guide wheel 31. The greater the deflection of the guide wheel 31, the higher the height of the sowing device 2 off the ground. At the same time, because the power output shaft of the traction machine 1 passes through... The multi-stage transmission rod is connected to the sowing device 2. Therefore, in this invention, the transmission rod in the middle of the multi-stage transmission rod is changed to a telescopic rod 21 with an adaptively adjustable length. Even when the sowing device 2 is lifted, the adaptive contraction of the telescopic rod 21 can still allow the sowing device 2 to rotate around the pin 9, while ensuring that the power output remains connected. When the guide wheel 31 deflects significantly, that is, when the driver operates the traction machine 1 to adjust the general direction or turn around, the sowing device 2 will be automatically lifted off the ground. At this time, the power to lift the independent walking wheels of the sowing device 2 off the ground is released. Therefore, the sowing operation of the sowing roller of the sowing hanger 2 is disconnected. Even though the negative pressure material distribution mechanism is still in the material suction state, the sowing hanger 2 no longer continues a series of operation steps such as furrowing, seeding, covering soil and compaction. This achieves the effect of disconnecting the sowing operation when turning, which is more in line with the actual production situation. In addition, the furrowing, covering soil and compaction operations stop simultaneously to prevent damage to the field perimeter when turning, which further ensures the uniformity and efficiency of the sowing operation. Moreover, when the tractor 1 makes a small adjustment to the travel angle to ensure the linearity of the sowing operation, it will not affect the normal sowing operation, which is in line with the actual production situation.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
