[0037] 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.
[0038] The purpose of this invention is to provide a new type of seed rope laying machine for smart community breeding, which can avoid the seed rope from contacting and rubbing against the furrow opener during the sowing process. This solves the problem that existing seed rope laying machines are prone to contact and friction between the seed rope and the furrow opener, which not only causes great damage to the seed rope, but also damages or causes the seeds on the seed rope to fall off, thereby reducing the sowing quality and sowing efficiency.
[0039] 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.
[0040] This embodiment proposes a seed rope laying machine 100 for smart community breeding, which mainly includes a frame traction device 1, a ground wheel mechanism, a seed rope laying device 2, and a seed rope micro-control system 20, as detailed below:
[0041] like Figure 1 and Figure 2 As shown, the frame traction device 1 includes a frame 3, a fertilizer box bracket 4, a suspension traction frame 5, a fertilizer box 6, and a fertilizer shovel 7. The fertilizer box 6 is fixed to the frame 3 by the fertilizer box bracket 4. The fertilizer box bracket 4, the suspension traction frame 5, and the fertilizer shovel 7 are all connected to the frame 3 by U-shaped clamps 12. Specifically, the suspension traction frame 5 is used to connect to a traction mechanism such as a tractor. The fertilizer box bracket 4 is arranged facing upwards, and its top supports and fixes the fertilizer box 6. Preferably, the fertilizer box 6 is connected to the fertilizer box bracket 4 by bolts. The fertilizer shovel 7 is arranged facing downwards and is slightly higher than the lowest end of the frame 3. Multiple fertilizer shovels 7 are arranged at intervals along the width extension direction of the frame 3 (this width extension direction is generally perpendicular to the travel direction of the traction mechanism).
[0042] It should be noted that the aforementioned fertilizer box 6 is preferably an existing electric fertilizer box, with multiple fertilizer discharge boxes arranged at its bottom along the width extension direction of the frame 3, and the fertilizer discharge boxes are preferably arranged in a one-to-one correspondence with the fertilizer shovels 7. A square shaft 10 is also rotatably mounted at the bottom of the electric fertilizer box, and the square shaft 10 is arranged parallel to the width extension direction of the frame 3, and as shown... Figure 2 As shown, the square shaft 10 passes through each fertilizer discharge box, and the fertilizer can be discharged from the fertilizer discharge box by driving the square shaft 10 to rotate; the square shaft 10 is generally a hexagonal shaft, and the specific structural layout and fertilizer discharge principle of the existing electric fertilizer box will not be described in detail here.
[0043] like Figure 3 and Figure 4As shown, the ground wheel mechanism includes a ground wheel 55, a ground wheel support 56, a ground wheel mounting frame 57, and a ground wheel transmission device 11. The ground wheel transmission device 11 includes a first chain 9, a drive shaft 13, a second chain 14, and a sprocket 16. Specifically, the ground wheel support 56 is fixed to the frame 3 by a U-shaped clamp 12 and is located at the rear of the frame 3. The ground wheel mounting frame 57 is connected to the ground wheel support 56. The ground wheel 55 is rotatably mounted on the bottom end of the ground wheel mounting frame 57, and the drive shaft 13 is fixedly mounted on the top end of the ground wheel mounting frame 57 and the center of the ground wheel 55. The two drive shafts 16... 3. Both ends of the drive shaft 13, which is parallel to and located at the top of the ground wheel mounting frame 57, are fitted with sprockets 16. The left end of the drive shaft 13 on the ground wheel 55 is also fitted with a sprocket 16. The sprockets 16 on the ground wheel 55 and the left end sprocket 16 of the drive shaft 13 at the top of the ground wheel mounting frame 57 are arranged on the same side. The two sprockets 16 arranged on the same side are connected by a chain 2 14. A driven sprocket is fitted on the square shaft 10. The two ends of the chain 1 9 are respectively connected to the driven sprocket and the right end sprocket 16 of the drive shaft 13 at the top of the ground wheel mounting frame 57. The chain tensioning device 8 is fixed to the frame 3 by a U-shaped clamp 12. The chain tensioning device 8 is arranged in conjunction with the chain 1 9. The chain tensioning device 8 can control the tension of the chain 1 9 during transmission. Under normal circumstances, the ground wheel 55 rolls on the ground, which drives the chain 2 14. The chain 2 14 transmits torque to the chain 1 9 through the drive shaft 13 at the top of the ground wheel mounting bracket 57, driving the chain 1 9 to transmit torque to the square shaft 10 on the fertilizer box 6, causing the square shaft 10 to rotate, thus achieving the purpose of fertilizer delivery and ensuring good synchronization between fertilizer delivery and the ground wheel 55.
[0044] Specifically, preferably, the rear bottom of the wheel support 56 is rotatably connected to the front bottom of the ground wheel mounting bracket 57 via a pin, such as... Figure 3 and Figure 4 As shown, a crossbeam is provided at the top front of the wheel mounting frame 57 and the top rear of the wheel support 56. The crossbeams of the wheel mounting frame 57 and the wheel support 56 are connected by a screw 17. The two ends of the screw 17 are provided with threaded sections with opposite directions of rotation, which are threaded to the crossbeams of the wheel mounting frame 57 and the wheel support 56, respectively. By rotating the screw 17 in both directions, the crossbeams of the wheel mounting frame 57 and the wheel support 56 can be moved closer and further apart, thereby adjusting the tilt angle of the wheel mounting frame 57 relative to the wheel support 56, and thus adjusting the ground clearance of the wheel 55. In addition, the screw 17 has a self-locking characteristic. Once the tilt angle of the wheel mounting frame 57 relative to the wheel support 56 is adjusted to the correct position, stopping the rotation of the screw 17 will maintain the relative position of the wheel mounting frame 57 and the wheel support 56.
[0045] In this embodiment, based on the adjustable relative positions of the ground wheel mounting frame 57 and the ground wheel support 56, the ground wheel mechanism is further provided with a tensioning mechanism 15. The tensioning mechanism 15 is located on the inner ring of the second chain 14 and is mounted on the ground wheel mounting frame 57. The tensioning mechanism 15 is used to adjust the tension of the second chain 14 to ensure that the second chain 14 is always in a taut state. Specifically, as shown... Figure 4 As shown, the tensioning mechanism 15 is rotatably mounted on the ground wheel mounting bracket 57 via a rotating shaft. The tensioning mechanism 15 includes an upper tensioning sprocket, a lower tensioning sprocket, and a tension spring. The adjustment method is as follows: before the machine operates, the upper tensioning sprocket is positioned above the slack side of chain 2 14, and the lower tensioning sprocket is positioned below the slack side of chain 2 14. Simultaneously, due to the action of the tension spring, the upper tensioning sprocket exerts a downward force on chain 2 14. Furthermore, since the upper and lower tensioning sprockets are on the same rotating shaft, the lower tensioning sprocket exerts an upward force on chain 2 14, thereby achieving the tensioning purpose. This tensioning mechanism 15 is an existing tensioning technology, and its details will not be elaborated upon here.
[0046] In this embodiment, a chain tensioning device 8 for adjusting the tension of chain 9 is also provided on the frame 3. The chain tensioning device 8 is preferably fixed to the frame 3 by a U-shaped clamp 12. The chain tensioning device 8 is a prior art technology, and its details will not be described further here.
[0047] It should be noted that the aforementioned ground wheel mechanism is generally located at the rear of frame 3, and multiple sets are arranged along the width extension direction of frame 3, such as... Figure 1 As shown, two sets of ground wheel mechanisms are set on the frame 3. In order to ensure the stability of the frame 3 as it moves with the traction mechanism, it is preferable that the two sets of ground wheel mechanisms are symmetrically distributed on the frame 3.
[0048] In this embodiment, the seed rope laying device 2 is fixed to the frame 3 by a U-shaped clamp 12 and is positioned directly behind the fertilizer shovel 7. The seed rope laying device 2 is generally arranged in multiple sets along the width extension direction of the frame 3 and is arranged in a one-to-one correspondence with the fertilizer shovel 7. At the same time, the seed rope laying device 2 and the aforementioned ground wheel transmission device 11 are arranged crosswise in the width extension direction of the frame 3.
[0049] Specifically, such as Figures 5-6As shown, the seed rope laying device 2 includes a contour-following four-bar linkage 18, a pressure spring 19, a seed rope reel 22, a guide roller 23, a main crossbeam 24, a soil compactor arm 25, a soil compactor 26, and a seed rope furrow opener 27. The contour-following four-bar linkage 18 is fixed to the frame 3 by a U-shaped clamp 12. The main crossbeam 24 is fixed behind the contour-following four-bar linkage 18. The seed rope micro-control system 20, the soil compactor arm 25, and the seed rope furrow opener 27 are all fixed to the main crossbeam 24. The soil compactor 26 is connected to the soil compactor arm 25. The soil compactor 26 is generally installed at the same height as the seed rope furrow opener 27 to ensure the effectiveness of soil compaction. A wrench is connected to the soil compactor 26, and the wrench is movably connected to the soil compactor support arm 25. This wrench, in conjunction with a spring, allows adjustment of the soil compaction pressure. The principle is as follows: a spring is located at the lower end of the soil compactor support arm 25. One end of this spring is connected to the main crossbeam 24, and the other end is connected to the lower end of the wrench. Adjusting the wrench by inserting it into different holes on the soil compactor support arm 25 will cause the spring to experience different forces, thus changing the soil compaction pressure. An upwardly extending bracket is provided on the main crossbeam 24. The seed rope reel 22 and the guide roller 23 are both rotatably mounted on this bracket. The seed rope reel 22 is used to reel in and out the seed rope, and the guide roller 23 is used to guide the seed rope reeled in and out of the seed rope reel 22. Figure 6As shown, the four-bar linkage 18 mainly includes a front stamping plate 38, an upper connecting rod 28, a lead screw 29, a rear stamping plate 30, a spline sleeve 31, a connecting plate 32, a spline shaft 33, a support plate 34, a scraper 35, a pressing roller 36, and a lower connecting rod 37. The front stamping plate 38 is fixed to the frame 3 by a U-shaped clamp 12. The front stamping plate 38 and the rear stamping plate 30 are arranged opposite each other, and the front stamping plate 38 and the rear stamping plate 30 are respectively provided with a front clamp and a rear clamp. The two ends of the upper connecting rod 28 are hinged to the front clamp and the rear clamp, respectively. The lower connecting rod 37 is located below the upper connecting rod 28, and the two ends of the lower connecting rod 37 are hinged to the front clamp and the rear clamp, respectively. 1. Located between the front stamping plate 38 and the rear stamping plate 30, and the spline sleeve 31 is fixed to the rear stamping plate 30 through the connecting plate 32. The lead screw 29 is movably sleeved in the top of the spline sleeve 31. The spline shaft 33 is sleeved in the bottom of the spline sleeve 31 and is connected to the spline sleeve 31 through splines. After the spline shaft 33 is splined to the spline sleeve 31, it can be ensured that the spline sleeve 31 and the spline shaft 33 can only move relative to each other axially and cannot rotate relative to each other. At the same time, the top of the spline shaft 33 is provided with an internal threaded hole and is threaded to the bottom of the lead screw 29. The bottom of the spline shaft 33 is fixed to the second bracket plate 34. The scraper 35 and the pressing roller 36 are connected to the second bracket plate 34 through bolts. As described above, the screw 29, spline shaft 33, and spline sleeve 31 combine to form a slide-like structure. Based on this, by rotating the screw 29, the spline shaft 33 can be driven to extend and retract axially relative to the spline sleeve 31, thereby adjusting the height of the press roller 36 from the ground, and thus adjusting the height of the seed rope furrow opener 27 from the ground (when performing sowing operations, the height of the seed rope furrow opener 27 from the ground is specifically reflected in the depth of penetration into the soil).
[0050] In this embodiment, two upper connecting rods 28 are provided along the width extension direction of the frame 3, and a lower connecting rod 37 is provided below each of the two upper connecting rods 28. That is, the front stamping plate 38 and the rear stamping plate 30 are connected by the two upper connecting rods 28 and the two lower connecting rods 37. A pressure spring 19 is connected between any upper connecting rod 28 and the front stamping plate 38, and the pressure spring 19 can apply pressure to the pressing roller 36. As a preferred embodiment, the pressure spring 19 is arranged at a rearward inclination, with its bottom end connected to the bottom of the front stamping plate 38 and its top end connected to the upper connecting rod 28. The connection position of the pressure spring 19 on the upper connecting rod 28 can be adjusted along the length direction of the upper connecting rod 28. Figure 6 As shown, in the middle of the upper connecting rod 28, there are three slots spaced apart along the length of the upper connecting rod 28 for attaching the pressure spring 19. The pressure spring 19 can be attached to different slots to change the magnitude of the downward pressure of the pressure spring 19. The further back the top of the pressure spring 19 is, the more the pressure spring 19 is stretched as a whole, and the greater the downward pressure. At the same time, the pressure spring 19 is also to ensure the stability of the rope seeding unit when it is working.
[0051] In this embodiment, a seed rope guide tube 271 is provided on the rear side of the seed rope opener 27. The seed rope guide tube 271 is preferably a bent tube structure with the bottom bent backward, and the bottom of the bent tube structure is close to the bottom of the seed rope opener 27. This design is conducive to the seed rope being basically horizontal when it is discharged, and reduces the height of the seed rope from the ground when it is discharged, which is conducive to the accurate placement of the seed rope.
[0052] In this embodiment, as Figure 5 As shown, the pressing roller 36 is generally a contour pressing roller, and it is generally preferred that the pressing roller 36, the seed rope trencher 27 and the soil covering pressing device 26 are arranged in sequence from front to back. The mud scraper 35 is located at the rear oblique upper part of the pressing roller 36 and is used to scrape the mud off the pressing roller 36.
[0053] In this embodiment, the height of the seed rope reel 22 and the guide roller 23 on the bracket on the main crossbeam 24 is preferably adjustable. The bracket has two vertically extending strip-shaped holes. The seed rope reel 22 is rotatably mounted on a shaft. The ends of the shaft and the guide roller 23 are respectively installed in the two strip-shaped holes, and their positions are fixed by threaded connections between the wing nuts and the ends of the shaft or guide roller 23. Loosening the wing nuts allows adjustment of the height of the seed rope reel 22 and the guide roller 23 within the corresponding strip-shaped holes. Figure 8 and Figure 9 As shown, the shaft of the seed rope disc 22 and the guide roller 23 are preferably arranged in parallel vertically.
[0054] In this embodiment, preferably, the aforementioned disc shaft is also equipped with a damper 21 capable of controlling the rotation of the seed rope disc 22. The damper 21 can adopt one of the following two configuration forms: the first type of damper is a common spring damper, such as... Figure 8 As shown, it includes a wing nut 49, a spring 50, and a conical wheel 51. Both the spring 50 and the conical wheel 51 are mounted on the disc shaft, with the small end of the conical wheel 51 contacting one axial side of the seed rope disc 22. The wing nut 49 is threaded to the end of the disc shaft, pressing the spring 50 against the large end of the conical wheel 51. Damping is generated through the friction between the spring 50 and the contact surface, which is more economical. The second type of damping uses a disc-type damper, such as... Figure 9As shown, it includes a wing nut 49, a conical wheel 51, a nut 52, a washer 53, and a connecting piece 54. The conical wheel 51, nut 52, washer 53, and connecting piece 54 are all mounted on the disc shaft. The conical wheel 51 is positioned in the same location as in the first type of damping. The connecting piece 54 is mounted on the disc shaft and bolted to the large end of the conical wheel 51. The nut 52 is located at the end of the connecting piece 54 furthest from the conical wheel 51. At least one washer 53 is placed between the nut 52 and the connecting piece 54. The wing nut 49 is threaded to the end of the disc shaft. The second type of damping has a bidirectional damping effect, and the damping magnitude is adjustable. Before use, the damping can be increased / decreased by rotating the nut 52 or changing the number of washers 53. Because it has bidirectional damping, in the event of stopping or unexpected situations, it can not only prevent the seed rope disc 22 from continuing to rotate due to inertia, but also prevent the seed rope disc 22 from reversing due to excessive inertia. Compared to the first type of damping, it is more precise and efficient. Therefore, the second damping structure is preferred in this embodiment.
[0055] In this embodiment, the seed rope micro-control system 20 includes an electric slide, a micro-motion main rod 43, a support plate 44, a micro-motion contact 45, a driver 46, a controller 47, and a DC-DC boost power supply 48. Figure 7 As shown, the electric slide table mainly includes a motor 39, a ball screw 40, a slider 41, and a stop plate 42 for supporting both ends of the ball screw 40. The electric slide table is existing technology, and its specific structural principle will not be elaborated here. However, it should be emphasized that in this embodiment, the arrangement direction of the ball screw 40, that is, the sliding direction of the slider 41, is parallel to the width extension direction of the aforementioned frame 3. The micro-motion main rod 43 is arranged vertically, with its bottom connected to one side of the slider 41, and the micro-motion main rod 43 is arranged perpendicular to the sliding direction of the slider 41. The support plate 44 is fixedly mounted to the top of the micro-motion main rod 43, and the micro-motion contact 45 is bolted to the support plate 44. The micro-motion contact 45 is perpendicular to the sliding direction of the slider 41 and the micro-motion main rod 43. Preferably, two sets of micro-motion contacts 45 are arranged parallel and spaced apart, with the seed rope placed between the two sets of micro-motion contacts 45. One end of the DC-DC boost power supply 48 is generally used for electrical connection to the battery of a tractor or other traction mechanism, while the other end is connected to the motor 39, driver 46, and controller 47 for power supply. In this embodiment, as shown... Figure 5 As shown, the seed rope micro-control system 20 is generally equipped with a protective shell. The electric slide, driver 46, controller 47 and DC-DC boost power supply 48 are all located inside the protective shell. The top of the micro-motion main rod 43 penetrates the top of the protective shell. The support plate 44 and two sets of micro-motion contacts 45 are located outside the protective shell and above it.
[0056] The above-mentioned seed rope micro-control system 20 always maintains a perpendicular operating direction to the traveling direction of the frame 3 during operation. Initially, the seed rope is placed between the two micro-motion tentacles 45. During the seed rope discharge process, the driver 46 transmits the program written by the controller 47 to the motor 39. The motor 39 drives the two micro-motion tentacles 45 to move in the opposite direction to the deviation direction of the seed rope according to the program, so as to achieve the purpose of real-time correction of the seed rope position and ensure that the seed rope is always kept in the center position of the seed rope guide tube 271 on the seed rope furrow opener 27, thereby reducing the friction between the seed rope and the inner wall of the seed rope guide tube 271 on the seed rope furrow opener 27.
[0057] The following example illustrates the operation method of the seed rope laying machine 100 for smart community breeding, using the example of connecting the seed rope laying machine 100 to a tractor for sowing operations.
[0058] The tractor is connected to the suspension traction frame 5 via a rear three-point suspension device and is in a floating state. The seed rope laying device 2 and the fertilizer shovel 7 are arranged facing each other. The screw 17 on the ground wheel transmission device 11 is adjusted so that the ground wheel 55 touches the ground, and the support arm 25 of the soil compactor is adjusted so that the soil compactor 26 touches the ground. The seed rope reel 22 completed by the intelligent seed rope weaving machine is installed on the aforementioned bracket, and the initial seed rope is combed. After the initial seed rope is passed around the guide rope roller 23, it passes sequentially through the gap between the two micro-movement contacts 45 and the seed rope guide tube 271 on the seed rope opener 27.
[0059] Then, the tractor pulls the ground wheel 55 of the ground wheel transmission device 11 forward. At the same time, as the ground wheel 55 rotates, it drives the chain 2 14 to drive. The chain 2 14 transmits torque to the chain 1 9 through the transmission shaft 13 at the top. The chain 1 9 is connected to the square shaft 10 and transmits the torque to it, so that the fertilizer box 6 delivers fertilizer and the machine moves forward in sync. Adjusting the lead screw 29 on the contour four-bar linkage 18 positioned behind the fertilizer shovel 7 allows the pressing roller 36 to press down loose soil and the seed rope furrow opener 27 to have a suitable furrowing depth. The seed rope furrow opener 27 furrows under its own weight and the pressure spring 19. The seed rope micro-control system 20 always keeps its working direction perpendicular to the machine's working direction. By adjusting the controller 47 and inputting a suitable speed and distance, the motor 39 will drive the two micro-motion contacts 45 to move in the opposite direction to the seed rope's deviation direction, achieving real-time correction of the seed rope's position. This ensures that the seed rope always remains in the center position of the seed rope guide tube 271 on the seed rope furrow opener 27, reducing friction between the seed rope and the inner wall of the seed rope guide tube 271 on the seed rope furrow opener 27, minimizing seed rope damage, and ensuring stable sowing operations.
[0060] It should be noted that before operation, the appropriate number of shims 53 should be selected and the nut 52 should be adjusted so that the seed rope reel 22 has the appropriate damping force.
[0061] By adjusting the angle of the support arm 25 of the soil compactor, the appropriate working height of the soil compactor 26 can be ensured, so as to ensure the gripping ability of the soil compactor 26 to prevent slippage, improve the soil compaction effect, thereby speeding up the operation and improving the operation efficiency.
[0062] In summary, the seed rope laying machine and its operating method proposed in this solution for intelligent community breeding can complete a series of functions such as ditching, fertilization, seed rope laying, and soil covering and compaction in a single field operation, realizing the multi-functionality of the seed rope laying machine. The driving force of the fertilizer box power component, namely the square shaft 10, is provided by the ground wheel transmission device 11, which can drive the fertilizer box to apply fertilizer synchronously while the ground wheel rotates forward with the traction mechanism, ensuring the synchronicity of fertilization to a certain extent. The matching seed rope laying device 2 integrates contour compaction, seed rope laying, and soil covering and compaction, and is equipped with a seed rope micro-control system 20 to ensure that the seed rope is always located in the center of the seed rope guide tube 271 during the seed rope laying process, reducing the friction between the seed rope and the inner wall of the seed rope guide tube 271. Two selectable damping devices are also provided on the seed rope disc 22 to adapt to different needs. The above-mentioned multi-functional seed rope laying machine can also be configured with different row spacing according to the actual planting mode requirements, and has the characteristics of fast seed rope laying speed, high efficiency, and minimal seed rope damage.
[0063] Therefore, it is evident that the multifunctional seed rope laying machine proposed in this solution creatively solves the problems existing in the current seed rope laying operation technology. It has the characteristics of saving farming time, saving costs, increasing efficiency, being environmentally friendly and sustainable. It can complete the efficient and rapid laying of seed ropes and achieve a win-win situation for smart community breeding in terms of economy, society and ecology.
