Description

Technical Field

[0001] This utility model relates to the field of pulping machine technology, specifically a double-row spring tooth pulping machine with high adaptability to ground conditions. Background Technology

[0002] In the process of stubble burial in paddy fields, the rice straw needs to be buried in the soil for natural decomposition. This not only solves the air pollution caused by burning straw but also improves soil fertility and provides a good sowing environment.

[0003] Existing straw compactors typically use a rotating connection between the straw compactor plate and the machine cover to allow the straw compaction teeth on the plate to penetrate deep into the ground for stubble burial. However, when encountering large rocks or hard soil layers underground, the rigid rotating connection between the straw compactor plate and the machine cover lacks cushioning, making it difficult for the straw compactor plate to adapt to the ground slope. This not only easily damages the straw compaction teeth but also damages the rotating connection between the straw compactor plate and the machine cover when the straw compaction teeth rebound after being obstructed. This not only requires frequent replacement of parts, which is uneconomical, but also affects the overall straw compaction efficiency of the machine. Utility Model Content

[0004] Given that the existing technology has problems such as the rotating connection between the straw pressing plate and the machine cover being too rigid and lacking cushioning, and the straw pressing plate not being able to adapt well to the ground, this utility model provides a double-row spring tooth pulverizer with high adaptability to the ground.

[0005] This utility model provides a double-row spring tooth slurry machine with high adaptability to the ground, including a slurry device; the slurry device includes: a machine cover, a rubber plate installed on the outside of the machine cover, a straw pressing plate installed on the outside of the rubber plate, and a plurality of straw pressing spring teeth set on the straw pressing plate for the first stubble burying.

[0006] Furthermore, the rubber plate is provided with a first pad and a second pad, and the first pad, the rubber plate and the straw pressing plate are fixedly connected by bolts; the second pad, the rubber plate and the machine cover are fixedly connected by bolts.

[0007] Furthermore, a scraper plate is rotatably mounted on the outer side of the grass pressing plate, and several scraping teeth for secondary stubble burial are provided on the lower side of the scraper plate.

[0008] Furthermore, the scraping spring teeth include an inclined section mounted to the scraping plate and a straight section integrally formed with the inclined section and parallel to the scraping plate.

[0009] Furthermore, the angle between the straight segment and the inclined segment is 135 degrees.

[0010] Furthermore, the grass-pressing bullet teeth are curved and can penetrate deep into the ground.

[0011] Furthermore, a first bracket is installed on the back of the machine cover, and an elongated hole is provided at the end of the first bracket; a first support rod is installed on the back of the scraper plate, and the first support rod and the first bracket are rotatably connected by a pin installed in the elongated hole.

[0012] Furthermore, a second bracket is installed on the back of the machine cover, and a second support rod that rotates in cooperation with the second bracket is installed on the back of the grass pressing plate. A spring is sleeved on the second support rod; the spring is disposed between the second bracket and the grass pressing plate.

[0013] Furthermore, a limiting component is provided between the grass pressing plate and the machine cover to limit the bending angle of the rubber plate. The limiting component includes a limiting plate fixed on the machine cover and a baffle fixedly installed on the grass pressing plate. The limiting plate has an arc hole, and a column that is slidably connected in the arc hole is fixedly installed on the baffle.

[0014] Furthermore, a smoothing mechanism is installed at the distal end of the scraper plate. The smoothing mechanism includes: a first push-pull rod, a second push-pull rod, a third push-pull rod, a fourth push-pull rod, and a telescopic drive element mounted on the scraper plate. The two ends of the first push-pull rod are respectively rotatably connected to the telescopic end of the telescopic drive element and the fourth push-pull rod. The two ends of the second push-pull rod are respectively rotatably connected to the telescopic end of the telescopic drive element and the third push-pull rod. The third push-pull rod is rotatably connected to the end of the fourth push-pull rod. A smoothing plate is fixedly mounted on the third push-pull rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model patent utilizes a flexible rubber plate on the outside of the machine cover, allowing the stubble pressing plate to better conform to the ground, thus enabling the stubble pressing teeth on the plate to penetrate deeper into the ground for stubble burying. When the stubble pressing teeth encounter large stones or hard soil layers, the flexible rubber plate provides cushioning, reducing damage to the teeth and plate, and enhancing the adaptability of the slurrying device to the ground. This allows for slurrying operations even in complex ground environments due to the high adaptability of the flexible rubber plate, thus enhancing the practicality of the slurrying machine.

[0017] 2. This utility model patent utilizes a scraping plate on the outer side of the straw pressing board, with scraping teeth on the scraping plate, to perform secondary stubble burying on the soil. This ensures that any straw stubble not fully buried by the pressing teeth is more thoroughly embedded in the soil, guaranteeing complete stubble burying. The double-row tooth structure further ensures that all straw stubble is buried in the soil, preserving soil fertility and providing a better environment for rice sowing.

[0018] 3. This utility model patent enhances the quality of land leveling after slurrying by installing a smoothing mechanism at the far end of the scraper plate. The smoothing mechanism, driven by extension and retraction of the drive element, flips and unfolds the smoothing plate to the same plane as the scraper plate, and the movement of the agricultural machinery smooths the slurryed land. This structure not only smooths land that extends beyond the length of the slurrying machine during slurrying but also smooths uneven ground between adjacent slurrying surfaces, increasing the area of ​​land leveling and thus ensuring the quality of the slurrying operation and the flatness of the land surface.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Please refer to Figures 1 to 8 This utility model provides a double-row spring tooth pulper with high adaptability to ground conditions, in order to Figure 1 For example, the end of the scraper plate 4 that is far from the connecting frame 10 is the far end.

[0035] like Figures 1 to 8 As shown, this utility model provides a double-row spring tooth slurry machine with high adaptability to the ground, including a slurry device; the slurry device includes: a machine cover 1, a rubber plate 2 installed on the outside of the machine cover 1, a straw pressing plate 3 installed on the outside of the rubber plate 2, and a plurality of straw pressing spring teeth 31 set on the straw pressing plate 3 for the first stubble burying.

[0036] In this embodiment, a flexible rubber plate 2 is installed on the outside of the machine cover 1, allowing the straw pressing plate 3 to better adapt to and adhere to the ground. This enables the straw pressing teeth 31 on the straw pressing plate 3 to penetrate deeper into the ground for stubble burying. When the straw pressing teeth 31 encounter large rocks or hard soil layers, the flexible rubber plate 2 provides cushioning for the straw pressing teeth 31 and the straw pressing plate 3, reducing damage to them and enhancing the adaptability of the slurrying device to the ground. This allows for slurrying operations even in complex ground environments thanks to the high adaptability of the flexible rubber plate 2, thus enhancing the practicality of the slurrying machine.

[0037] To further explain, such as Figure 1 As shown, the double-row spring tooth pulverizer with high adaptability to the ground also includes a connecting frame 10 that can be connected and installed with agricultural machinery. A dual-shaft output transmission gearbox 11 is set in the middle of the connecting frame 10. Pulverizing devices are symmetrically arranged on both sides of the connecting frame 10. Drive linkage mechanisms 12 are respectively installed on the output shafts on both sides of the dual-shaft output transmission gearbox 11. Gearboxes 13 are installed at the ends of the drive linkage mechanisms 12. Pulverizers 14 parallel to the drive linkage mechanisms 12 are set in the inner cavity of the machine cover 1. One end of the pulverizer 14 is rotatably installed with the gearbox 13. The power output shaft of the agricultural tractor is connected to the dual-shaft output transmission gearbox 11. The agricultural tractor is started, and the dual-shaft output transmission gearbox 11 is driven to rotate. Then, the drive linkage mechanisms 12 connected to the output shafts on both sides of the dual-shaft output transmission gearbox 11 rotate accordingly. Through the cooperation of the gearbox 13, the pulverizer 14 rotates to perform pulverizing operations.

[0038] To further explain, such as Figure 1 As shown, the top of the connecting frame 10 is equipped with a hydraulic cylinder 15 for controlling the opening or closing of the two side covers 1. The extension or retraction of the telescopic end of the hydraulic cylinder 15 drives the opening or bending of the drive linkage mechanism 12, thereby driving the opening or closing of the cover 1. This allows the pulper 14 to be opened to a parallel state during pulping operations and to be closed to save storage space when the pulping operation is finished.

[0039] like Figure 3 As shown, the rubber plate 2 is provided with a first pad 22 and a first pad 23. The first pad 22, the rubber plate 2 and the straw pressing plate 3 are fixedly connected by bolts; the first pad 23, the rubber plate 2 and the machine cover 1 are fixedly connected by bolts.

[0040] In this embodiment, the arrangement of the first pad 22 and the first pad 23 distributes the pressure of the bolt on the rubber plate 2 evenly on the pads, preventing damage to the rubber plate 2 due to the pressure of the bolt, ensuring the life of the rubber plate 2, and is more economical.

[0041] like Figure 2As shown, a scraper plate 4 is rotatably mounted on the outer side of the straw pressing plate 3, and several scraping teeth 41 for secondary stubble burying are provided on the lower side of the scraper plate 4.

[0042] This embodiment uses a scraper plate 4 on the outside of the straw pressing plate 3, and scraping teeth 41 on the scraper plate 4 to perform secondary stubble burying on the land. This ensures that any straw stubble not fully buried by the straw pressing teeth 31 is more thoroughly buried in the soil, guaranteeing the completeness of the stubble burying operation. The double-row tooth structure further ensures that all straw stubble is buried in the soil, thus preserving soil fertility and providing a better environment for rice sowing.

[0043] like Figure 2 and Figure 4 As shown, the scraping spring tooth 41 includes an inclined section 411 that is installed with the scraping plate 4 and a straight section 412 that is integrally formed with the inclined section 411 and parallel to the scraping plate 4.

[0044] To further clarify, the angle between straight segment 412 and oblique segment 411 is 135 degrees.

[0045] To further explain, the grass-pressing bullet teeth 31 are curved and can penetrate deep into the ground.

[0046] In this embodiment, the connecting frame 10 is connected to the agricultural machinery. As the agricultural machinery moves, the curved grass-pressing spring teeth 31 can extend into a deeper part of the soil surface, quickly burying the grass stubble into the soil and completing the first stubble burying operation. At this time, a small part of the grass stubble is still exposed. The remaining exposed grass stubble is then buried into the soil by scraping the straight section 412 of the spring teeth 41.

[0047] To further explain, the first burial involves burying the straw stubble deeper into the ground using the curved straw-pressing spring teeth 31, while the second burial involves burying the exposed straw stubble in a shallower position into the soil using the straight section 412 of the flattening spring teeth 41. The combination of the two burial processes ensures thorough burial.

[0048] like Figure 1 , Figure 6 and Figure 8 As shown, a first bracket 5 is installed on the back of the machine cover 1, and an elongated hole 51 is opened at the end of the first bracket 5; a first support rod 6 is installed on the back of the scraper plate 4, and the first support rod 6 and the first bracket 5 are rotatably connected by a pin 61 installed in the elongated hole 51.

[0049] Furthermore, a second bracket 7 is installed on the back of the machine cover 1, and a second support rod 8 that rotates in cooperation with the second bracket 7 is installed on the back of the grass pressing plate 3. A spring 81 is sleeved on the second support rod 8; the spring 81 is located between the second bracket 7 and the grass pressing plate 3.

[0050] In this embodiment, the position of the scraper plate 4 can be adjusted adaptively by sliding the pin 61 in the elongated hole 51. In conjunction with the rotation of the first bracket 5, the tilt angle of the scraper plate 4 can be flexibly adjusted, so that the scraper plate 4 is more closely attached to the ground, which facilitates the deep-level operation of the scraping teeth 41 on the scraper plate 4.

[0051] Furthermore, a flat washer is provided on the second support rod 8, and a spring 81 is clamped between the flat washer and the second bracket 7. When the grass-pressing teeth 31 on the grass-pressing plate 3 penetrate deep into the ground for stubble burial, the spring 81 is compressed, allowing the grass-pressing plate 3 to fit more tightly against the ground, facilitating the burial of the grass-pressing teeth 31. If there are hard clods of soil or stones under the ground, the grass-pressing plate 3 will rebound due to resistance. The spring 81 acts as a buffer against the rebound of the grass-pressing plate 3, which not only protects the stability of the connection between the grass-pressing plate 3 and the rubber plate 2, but also reduces damage to the grass-pressing teeth 31.

[0052] like Figure 7 As shown, a limiting component 21 is provided between the grass pressing plate 3 and the machine cover 1 to limit the bending angle of the rubber plate 2. The limiting component 21 includes a limiting plate 211 fixed on the machine cover 1 and a baffle 212 fixedly installed on the grass pressing plate 3. The limiting plate 211 has an arc hole 213, and a column 214 that is slidably connected in the arc hole 213 is fixedly installed on the baffle 212.

[0053] In this embodiment, the rotation of the column 214 in the arc hole 213 allows the rubber sheet 2 to be bent within a limited range, achieving maximum adaptability to the ground slope while protecting the lifespan of the rubber sheet 2.

[0054] To further explain, when the bending of the rubber plate 2 makes the grass pressing plate 3 closer to the ground, the arc hole 213 abuts against the column 214, applying a reaction force to the grass pressing plate 3, so that the grass pressing plate 3 can be pressed to fit more closely to the ground, and the grass pressing spring tooth 31 can penetrate deeper into the ground for better burial.

[0055] To further clarify, the column 214 can be a bolt threaded to the baffle 212, or a pin welded to the baffle 212.

[0056] Furthermore, the column 214 can be mounted on the limiting plate 211, and an arc hole 213 corresponding to the column 214 can be opened on the baffle 212. The same effect can be achieved by sliding the column 214 and the arc hole 213.

[0057] like Figure 5As shown, a smoothing mechanism 9 is installed at the far end of the scraper plate 4. The smoothing mechanism 9 includes: a first push-pull rod 92, a second push-pull rod 93, a third push-pull rod 94, a fourth push-pull rod 95, and a telescopic drive element 91 installed on the scraper plate 4. The two ends of the first push-pull rod 92 are rotatably connected to the telescopic end of the telescopic drive element 91 and the fourth push-pull rod 95, respectively. The two ends of the second push-pull rod 93 are rotatably connected to the telescopic end of the telescopic drive element 91 and the third push-pull rod 94, respectively. The end of the third push-pull rod 94 is rotatably connected to the end of the fourth push-pull rod 95. A smoothing plate 96 is fixedly installed on the third push-pull rod 94.

[0058] In this embodiment, the telescopic drive element 91 extends to push the first push-pull rod 92 and the second push-pull rod 93 to rotate, and drives the third push-pull rod 94 to rotate. When the third push-pull rod 94 moves to the same horizontal line as the fourth push-pull rod 95, the smearing plate 96 installed on the third push-pull rod 94 aligns with the scraper plate 4. At this time, the movement of the agricultural machinery can drive the smearing plate 96 to smooth the ground. The smearing mechanism 9 is designed to smooth the land turned over during slurrying that exceeds the length range of the slurrying machine, and can also smooth the ground between adjacent slurrying work surfaces, increasing the range of land leveling and thus ensuring the flatness of the land surface.

[0059] Furthermore, the telescopic drive element 91 can be a hydraulic cylinder, an electric push rod, or a pneumatic cylinder.

[0060] Furthermore, the first push-pull rod 92, the second push-pull rod 93, the third push-pull rod 94, and the fourth push-pull rod 95 are all inwardly curved rods, which can largely avoid external interference when rotating.

[0061] Furthermore, during the unfolding of the flipping assembly, the third push-pull rod 94 is the rod with the largest flipping angle. Therefore, the shorter length of the third push-pull rod 94 is beneficial for the effective flipping motion.

[0062] To further explain, the third push-pull rod 94 has a flip angle of 180 degrees. When the third push-pull rod 94 flips 180 degrees, the smearing plate 96 and the scraper plate 4 are on the same plane, completing the docking.

[0063] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
