Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulping machine technology, specifically a high-flatness bidirectional reversible pulping machine. Background Technology
[0002] When cultivating rice in paddy fields, the paddy fields must first be slurried to ensure the quality of rice growth.
[0003] Most existing rice pounders are tilting and folding type. They are driven by hydraulic cylinders to move the folding parts on both sides to the same horizontal plane. Then, an agricultural tractor drives the rice pounder to perform the pounding operation. Finally, the land is leveled by scrapers at the ends of the folding parts on both sides. However, the scrapers on both sides are easily affected by uneven land, so the land leveled by the scrapers on both sides is not on the same horizontal plane. As a result, the land is still uneven after leveling, which affects the operation quality of the rice pounder and further affects the growth of rice. Utility Model Content
[0004] In view of the problem that the working surface is still uneven after the scraper plate is leveled, which affects the operation quality of the pulping machine, the present invention provides a bidirectional reversible pulping machine with high flatness.
[0005] This utility model provides a high-flatness bidirectional reversible pulping machine, including a connecting frame, a left pulping device and a right pulping device respectively installed on both sides of the connecting frame; the left pulping device includes: a left machine cover, a left straw pressing plate disposed on the outside of the left machine cover, and two oppositely disposed locking plates disposed on the inside of the left straw pressing plate; a receiving cavity is formed between the two locking plates.
[0006] The right pulverizing device includes: a right machine cover, a right straw pressing plate disposed on the outside of the right machine cover, and a limiting protrusion disposed on the inside of the right straw pressing plate; when the left pulverizing device and the right pulverizing device are unfolded to a parallel state, the limiting protrusion is inserted into the receiving cavity to fix the left pulverizing device and the right pulverizing device together.
[0007] Furthermore, limit plates are fixedly installed on both the inner and outer sides of the left and right machine covers, and arc-shaped waist holes are provided on the limit plates; limit posts corresponding to be inserted into the arc-shaped waist holes are fixed on both the inner and outer sides of the left and right grass pressing plates.
[0008] Furthermore, the locking plate includes a vertical plate and an inclined plate integrally formed with the vertical plate and inclined outward.
[0009] Furthermore, the top two sides of the limiting protrusion are provided with inclined surfaces with the same inclination as the inclined plate.
[0010] Furthermore, scraper plates are rotatably mounted on the outer sides of both the left and right grass pressing plates.
[0011] Furthermore, each of the left and right stubble pressing plates is equipped with several stubble pressing teeth for the first stubble burial.
[0012] Furthermore, the scraper plate is equipped with several scraping teeth for secondary stubble application.
[0013] Furthermore, a smoothing mechanism is installed at the distal end of the scraper plate, the smoothing mechanism comprising: a flipping component installed on the back of the scraper plate and a smoothing plate installed on the flipping component.
[0014] Furthermore, the flipping assembly 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.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model patent installs two opposing locking plates on the inner side of the left pressing plate and a limiting protrusion that can engage with the locking plates on the inner side of the right pressing plate. This allows the left and right pulverizing devices to be positioned on the same plane through the engagement of the locking plates and the limiting protrusion when the pulverizing machine is in operation. This ensures the flatness of the ground after smoothing, guarantees the operation quality of the pulverizing machine, and further ensures the suitability of the rice growing environment.
[0017] 2. This utility model patent, by inserting a limiting post into the arc-shaped waist hole on the limiting plate, restricts the rotation angle of the left / right stubble pressing plate, allowing the left / right stubble pressing plate to adapt to the ground. When the rotation angle is at its maximum, the limiting post, locked at the end of the arc-shaped waist hole, applies a reaction force to the left / right stubble pressing plate, increasing the pressure of the left / right stubble pressing plate on the ground. This allows the several spring teeth installed on the left / right stubble pressing plate to better penetrate into the soil for stubble burying operations.
[0018] 3. This utility model patent utilizes a scraping plate on the outer side of the left / right straw pressing plate, 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 straw pressing teeth is more thoroughly embedded in the soil, guaranteeing complete stubble burying. The double-teeth structure further ensures that all straw stubble is buried in the soil, preserving soil fertility and providing a better environment for rice sowing.
[0019] 4. 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 plate is flipped and unfolded to the same plane as the scraper plate by a drive-rotating component, and the slurryed land is leveled by the movement of the agricultural machinery. This structure, by adding a smoothing plate, not only levels land that extends beyond the length of the slurrying machine during slurrying, but also levels un-smoothed areas 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.

Therefore, they should not be construed as limitations on this application.
[0037] Please refer to Figures 1 to 7 This utility model provides a high-flatness bidirectional reversible pulping machine, which... Figure 1 For example, the side of the left grass pressing plate 22 / right grass pressing plate 32 closest to the connecting frame 1 is the inner side, and the side farther away from the connecting frame 1 is the outer side; the end of the scraper plate 34 far away from the connecting frame 1 is the far end.
[0038] Please refer to Figures 1 to 7 This utility model provides a high flatness bidirectional reversible pulping machine, including a connecting frame 1, a left pulping device 2 and a right pulping device 3 respectively installed on both sides of the connecting frame 1; the left pulping device 2 includes: a left machine cover 21, a left straw pressing plate 22 disposed on the outside of the left machine cover 21, and two oppositely disposed locking plates 23 disposed on the inside of the left straw pressing plate 22; a receiving cavity 233 is formed between the two locking plates 23.
[0039] The right pulverizing device 3 includes: a right machine cover 31, a right straw pressing plate 32 disposed on the outside of the right machine cover 31, and a limiting protrusion 33 disposed on the inside of the right straw pressing plate 32; when the left pulverizing device 2 and the right pulverizing device 3 are unfolded to a parallel state, the limiting protrusion 33 is inserted into the receiving cavity 233 to fix the left pulverizing device 2 and the right pulverizing device 3 together.
[0040] In this embodiment, two opposing locking plates 23 are installed on the inner side of the left pressing plate 22, and a limiting protrusion 33 that can be locked onto the locking plates 23 is installed on the inner side of the right pressing plate 32. This allows the left pulverizing device 2 and the right pulverizing device 3 to be located on the same plane through the locking connection of the locking plates 23 and the limiting protrusion 33 when the pulverizing machine is in operation. This ensures the flatness of the ground after smoothing, guarantees the operation quality of the pulverizing machine, and further ensures the suitability of the rice growing environment.
[0041] In this embodiment, when the pulping machine is performing pulping operations, the left pulping device 2 and the right pulping device 3 are unfolded. During this process, the left pulping device 2 and the right pulping device 3 are fixedly installed on the same plane by the engagement of the protrusion and the two locking plates 23. Then, by connecting the connecting frame 1 to the agricultural machinery, the pulping machine performs pulping operations under the drive of the agricultural machinery. This locking connection structure keeps the left pulping device 2 and the right pulping device 3 on the same plane, thereby ensuring the flatness of the ground after pulping operations and preventing the impact of uneven ground on rice yield and quality.
[0042] like Figure 1 and 6 As shown, limit plates 4 are fixedly installed on the inner and outer sides of the left cover 21 and the right cover 31, and arc-shaped waist holes 41 are provided on the limit plates 4; the inner and outer sides of the left grass pressing plate 22 and the right grass pressing plate 32 are fixed with corresponding limit posts 5 that are inserted into the arc-shaped waist holes 41.
[0043] In this embodiment, by inserting the limiting post 5 into the arc-shaped waist hole 41 on the limiting plate 4, the rotation angle of the left grass pressing plate 22 / right grass pressing plate 32 can be limited. This allows the left grass pressing plate 22 / right grass pressing plate 32 to adapt to the ground. When the rotation angle is at its maximum, the limiting post 5, which is engaged at the end of the arc-shaped waist hole 41, applies a reaction force to the left grass pressing plate 22 / right grass pressing plate 32, increasing the pressure of the left grass pressing plate 22 / right grass pressing plate 32 on the ground. This allows the spring teeth installed on the left grass pressing plate 22 / right grass pressing plate 32 to better penetrate into the soil for stubble burying operations.
[0044] In this embodiment, by inserting the limiting post 5 into the arc-shaped waist hole 41 on the limiting plate 4, the straw pressing plate can be adapted to be close to the ground during the pulverizing operation, and the opening and closing angle between the straw pressing plate and the machine cover can be limited, thereby increasing the pressure of the straw pressing plate on the ground and ensuring the operation quality of the pulverizing machine.
[0045] like Figure 4 As shown, the snap-fit plate 23 includes a vertical plate 231 and an inclined plate 232 integrally formed with the vertical plate 231 and inclined outward.
[0046] Furthermore, the top two sides of the limiting protrusion 33 are provided with inclined surfaces 331 with the same inclination as the inclined plate 232.
[0047] In this embodiment, when the left pulping device 2 and the right pulping device 3 move to the point where the locking plate 23 contacts the limiting protrusion 33, as the left pulping device 2 and the right pulping device 3 continue to move, the inclined surface 331 of the limiting protrusion 33 slides on the inclined plate 232 of the locking plate 23, and finally slides into the receiving cavity 233. At this time, the left pulping device 2 and the right pulping device 3 unfold to the same horizontal plane and complete the docking and locking.
[0048] like Figure 5 As shown, scraper plates 34 are rotatably mounted on the outer sides of both the left grass pressing plate 22 and the right grass pressing plate 32.
[0049] Furthermore, both the left stubble pressing plate 22 and the right stubble pressing plate 32 are equipped with several stubble pressing teeth 321 for the first stubble burial.
[0050] Furthermore, the scraper plate 34 is equipped with several scraping teeth 341 for secondary stubble application.
[0051] This embodiment uses a scraper plate 34 installed on the outer side of the left and right straw pressing plates 22 and 32, with scraping teeth 341 on the scraper plate 34, to perform secondary stubble burying on the land. This ensures that any straw stubble not fully buried by the straw pressing teeth 341 is more thoroughly buried in the soil, guaranteeing the completeness of the stubble burying operation. The double-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.
[0052] Furthermore, by connecting the vehicle frame 1 to the agricultural machinery, the grass-pressing teeth 321 on the left grass-pressing plate 22 / right grass-pressing plate 32 can be inserted into the soil to perform the first stubble-burying operation under the drive of the agricultural machinery. The unburied grass stubble is then buried a second time by scraping the teeth 341, ensuring the thoroughness of the grass stubble burying and facilitating subsequent sowing operations.
[0053] like Figure 2 and Figure 7 As shown, a smoothing mechanism 6 is installed at the far end of the scraper plate 34. The smoothing mechanism 6 includes a flipping component 61 installed on the back of the scraper plate 34 and a smoothing plate 62 installed on the flipping component 61.
[0054] Furthermore, the flipping assembly 61 includes: a first push-pull rod 612, a second push-pull rod 613, a third push-pull rod 614, a fourth push-pull rod 615, and a telescopic drive element 611 mounted on the scraper plate 34; the two ends of the first push-pull rod 612 are respectively rotatably connected to the telescopic end of the telescopic drive element 611 and the fourth push-pull rod 615; the two ends of the second push-pull rod 613 are respectively rotatably connected to the telescopic end of the telescopic drive element 611 and the third push-pull rod 614; the third push-pull rod 614 is rotatably connected to the end of the fourth push-pull rod 615.
[0055] In this embodiment, the telescopic drive element 611 extends to push the first push-pull rod 612 and the second push-pull rod 613 to rotate, and drives the third push-pull rod 614 to rotate. When the third push-pull rod 614 moves to the same horizontal line as the fourth push-pull rod 615, the smearing plate 62 installed on the third push-pull rod 614 aligns with the scraper plate 34. At this time, the movement of the agricultural machinery can drive the smearing plate 62 to smooth the ground. The smearing mechanism 6 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.
[0056] Furthermore, the telescopic drive element 611 can be a hydraulic cylinder 11, an electric push-pull rod, or a pneumatic cylinder.
[0057] Furthermore, the first push-pull rod 612, the second push-pull rod 613, the third push-pull rod 614, and the fourth push-pull rod 615 are all inwardly curved rods, which can largely avoid external interference when rotating.
[0058] Furthermore, during the unfolding of the flipping assembly 61, the third push-pull rod 614 is the rod with the largest flipping angle. Therefore, the shorter length of the third push-pull rod 614 is beneficial for the effective execution of the flipping motion.
[0059] To further explain, the third push-pull rod 614 has a flip angle of 180 degrees. When the third push-pull rod 614 flips 180 degrees, the smearing plate 62 and the scraper plate 34 are on the same plane, completing the docking.
[0060] To further explain, such as Figure 1 and Figure 2As shown, both the left pulverizing device 2 and the right pulverizing device 3 are equipped with drive linkage mechanisms 7. A dual-shaft output transmission gearbox 8 is located in the middle of the connecting frame 1. The output shafts on both sides of the dual-shaft output transmission gearbox 8 are respectively installed with the drive linkage mechanisms 7 on both sides. A gearbox 9 is installed at the end of the drive linkage mechanism 7. Pulverizers 10 parallel to the drive linkage mechanisms 7 are installed in the inner cavity of the left engine cover 21 / right engine cover 31. One end of the pulverizer 10 is rotatably installed with the gearbox 9. The power output shaft of the agricultural tractor is connected to the dual-shaft output transmission gearbox 8. The agricultural tractor is started, which drives the dual-shaft output transmission gearbox 8 to rotate. In turn, the drive linkage mechanisms 7 connected to the output shafts on both sides of the dual-shaft output transmission gearbox 8 rotate. Through the cooperation of the gearbox 9, the pulverizer 10 rotates to perform pulverizing operations.
[0061] To further explain, such as Figure 1 and Figure 2 As shown, the top of the connecting frame 1 is equipped with a hydraulic cylinder 11 for controlling the expansion or contraction of the left pulverizing device 2 and the right pulverizing device 3. The extension or retraction of the telescopic end of the hydraulic cylinder 11 drives the extension or bending of the drive linkage mechanism 7, thereby driving the expansion or contraction of the left machine cover 21 / right machine cover 31. This allows the pulverizer 10 to be expanded to a parallel state for pulverizing operations. When pulverizing is finished, the pulverizer 10 can be retracted to save storage space.
[0062] 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.
