Description

Technical Field

[0001] This invention relates to the field of forestry land preparation equipment technology, and in particular to an integrated device for soil tillage and land preparation in forestry planting. Background Technology

[0002] A rotary tiller is a type of farming machinery with rotating blades at its core. Driven by a tractor or specialized power equipment, the blades rotate at high speed and cut into the soil to achieve functions such as turning, breaking up, and mixing organic matter. In the construction of new forest farms, rotary tillers can quickly remove surface weeds and residual roots, and turn over the compacted soil to the surface. Combined with organic fertilizer or humus, this improves soil aeration and fertility, providing a loose environment for seedling roots.

[0003] When rotary tillers are used for land preparation in forest farms, the high density of tree roots, vines, and perennial weeds on the surface makes the cutter shafts prone to entanglement. Furthermore, most existing rotary tillers use a double-helix cutter shaft arrangement, which creates an eccentric load during rotation, resulting in the highest concentration of weeds at the shaft connection point. When foreign objects become entangled on the cutter shaft, it not only increases the rotational resistance and load, but also increases the friction between the gearbox oil seal and the shaft. Prolonged exposure to this high friction causes rapid wear of the oil seal's sealing lip, thus reducing its lifespan.

[0004] Chinese patent application CN202210262539.9 discloses a blade shaft anti-weed entanglement device and a rotary tiller. This invention cuts by having a cutting device, driven by a cylindrical cam, drive a horizontal blade to reciprocate axially on the blade shaft. A tensioning device, driven by a grooved cam, reciprocates radially relative to the blade shaft, pulling and cutting weeds entangled on the shaft. However, the cutting device is relatively large, reducing the effective tillage area of ​​the rotary tiller. Although the first cover can shield the cutting device from weeds and other entanglements, gaps still exist between the first cover, the horizontal blade, and the blade shaft. Tree roots or vines can easily damage these gaps during entanglement, leading to damage to the cutting device and the gearbox's oil seals during continuous tillage. Furthermore, for highly resilient tree roots or vines, the horizontal blade, driven by the cam mechanism, is easily damaged during cleaning due to hard contact, such as cam rotation obstruction or breakage at the connection between the horizontal blade and the cam.

[0005] To address these issues, this invention proposes an integrated device for soil tillage and land preparation in forestry planting. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated device for soil tillage and land preparation in forestry planting, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated soil tillage and land preparation device for forestry planting, comprising a rotary tiller body, the rotary tiller body including a support frame, a gearbox and a cutter shaft, characterized in that it further comprises:

[0008] An anti-winding assembly is provided, which has multiple components located at the ends of the cutter shaft. It includes a mounting plate fixedly connected to the side wall of the support frame and / or the side wall of the gearbox. The mounting plate is provided with multiple annularly distributed arc-shaped blades. The arc-shaped blades are matched with the rotation direction of the cutter shaft. A mounting groove is provided on one side of the mounting plate, and multiple arc-shaped grooves matching the arc-shaped blades are provided in the mounting groove.

[0009] The transmission assembly, which is provided with multiple components and each is matched with the anti-winding assembly, includes a connecting plate slidably connected to the mounting groove and a transmission component located in the gearbox. The transmission component can drive the connecting plate to rotate and cause multiple arc-shaped blades to slide along the arc-shaped groove.

[0010] Preferably, the mounting plate is coaxially arranged with the cutter shaft, the arc of the arc groove is consistent with the arc of the arc blade, and the arc groove allows the arc blade to move radially along the cutter shaft.

[0011] Preferably, the arc-shaped blade includes an oblique first cutting surface and a horizontal second cutting surface, the shape of which matches the connection of the blade shaft.

[0012] Preferably, the transmission assembly further includes multiple connecting slots formed on the connecting plate and matching the arc-shaped groove. One end of the arc-shaped blade is fixedly connected to a connecting post inserted into the connecting slot of the arc-shaped groove box. A connecting pin is fixedly connected to the side of the connecting plate away from the mounting groove. An arc-shaped sliding groove matching the connecting pin is formed on the side wall of the gearbox and / or the side wall of the support frame. The center of the arc-shaped sliding groove is consistent with the axis of the cutter shaft. The end of the connecting pin away from the connecting plate is fixedly connected to the transmission component.

[0013] Preferably, the transmission component includes an oil reservoir fixedly connected to the gearbox, and a first piston rod and a second piston rod are respectively sealed and slidably connected to both ends of the oil reservoir cylinder. An electric push rod is fixedly connected to one end of the first piston rod, and a connecting cylinder is fixedly connected to the end of the second piston rod. A connecting rod is slidably connected inside the connecting cylinder, and the end of the connecting rod away from the connecting rod is fixedly connected to a connecting pin.

[0014] Preferably, pressure sensors are provided on the inner walls of each of the multiple oil storage tanks.

[0015] Preferably, a transverse cutting component is further provided between the anti-winding component and the conveying component. When the pressure sensor exceeds the threshold during radial contraction of the arc-shaped blade, the transverse cutting component enables multiple arc-shaped blades to move horizontally reciprocatingly.

[0016] Preferably, the transverse cutting assembly includes an arc-shaped tube, and multiple telescopic sleeves matching the arc-shaped blade are connected to the side wall of the arc-shaped tube. The end of the telescopic sleeve away from the arc-shaped tube is fixedly connected to a corresponding connecting post. An overflow pipe is connected to one side of the oil tank. An overflow valve is installed inside the overflow pipe. A piston plate is slidably connected inside the overflow pipe. An elastic element is installed between the piston plate and the overflow pipe. The overflow pipe is connected to the arc-shaped tube through a pipe.

[0017] Both the arc-shaped pipe and the overflow pipe are filled with hydraulic oil.

[0018] Preferably, the support frame and the gearbox are both provided with connecting seats at the connection ends with the cutter shaft. The second cutting surface has a stepped groove that matches the connecting seat. A third cutting surface is provided on the vertical surface of the stepped groove. A connecting block is provided on the bottom side of the second cutting surface away from the cutter shaft. When the multiple arc-shaped blades move horizontally, the connecting block can push the winding material wrapped around the cutter shaft to move to one side.

[0019] Preferably, a control box is provided on one side of the support frame, and a control unit is provided inside the control box. The multiple electric push rods and pressure sensors are respectively electrically connected to the control unit. The control box can form remote or direct control with the driving vehicle.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention, through the design of anti-winding components, arc-shaped blades, and transmission components, enables the special structure of the arc-shaped blades to form an isolation zone at the end of the cutter shaft during the initial stage of rotary tiller startup, preventing debris from damaging the connection between the gearbox and the cutter shaft. In addition, when a large amount of debris is wrapped around the end of the cutter shaft, the first cutting surface can cut the high-speed rotating debris under the rotation of the cutter shaft, effectively improving the accumulation of debris on the cutter shaft.

[0022] 2. With the cooperation of transmission components such as the oil reservoir, connecting plate and electric push rod, the present invention enables multiple arc-shaped blades to slide radially along the cutter shaft. The pressure between the first cutting surface and the debris increases rapidly, and the debris is pulled and cut during this process. When the arc-shaped blade returns to its original position, the second cutting surface can cut the debris located below it. The cut debris is gradually detached from the cutter shaft under the guidance of the arc surface of the arc-shaped blade, further improving the anti-entanglement effect of the cutter shaft and preventing a large amount of debris from accumulating at the end of the cutter shaft.

[0023] 3. With the addition of transverse cutting components such as overflow pipe, annular pipe, and telescopic sleeve, when the pressure in the oil tank is too high, the overflow valve opens and the piston plate in the overflow pipe slides, causing multiple arc-shaped blades to move laterally and, under the action of the connecting block, to pry open the entangled material. This avoids damage caused by hard contact between the arc-shaped blades and the entangled material, enabling the transmission component to have a pressure overflow effect. It also allows the arc-shaped blades to pry open the entangled material at the end of the cutter shaft, ensuring an effective isolation zone is formed between the arc-shaped blades and the end of the cutter shaft. Furthermore, when the arc-shaped blades are repositioned laterally, the third cutting surface can cut the entangled material on the side of the gearbox connecting seat, improving the cutting effect of the anti-entanglement component.

[0041] 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.

[0042] Example 1

[0043] When rotary tillers are used for land preparation in forest farms, the high density of tree roots, vines, and perennial weeds on the surface makes it extremely easy for the rotary tiller's cutter shaft to become entangled. Since the rotary cutters are typically arranged in a double-helix, the entanglement at the cutter shaft end is particularly pronounced. Once foreign matter becomes entangled on the cutter shaft, it not only increases the rotational resistance and load on the shaft, but also increases the friction between the gearbox oil seal and the shaft. Prolonged exposure to this high-friction condition causes rapid wear of the oil seal's sealing lip, thus reducing its service life. This embodiment was invented to solve the above problems.

[0044] Please see Figures 1 to 11 As shown, an embodiment of the present invention provides an integrated soil tillage and land preparation device for forestry planting, which includes a rotary tiller body 1. The rotary tiller body 1 includes a support frame 11, a gearbox 12 and a cutter shaft 13 that is connected to the gearbox 12 for transmission. It also includes an anti-winding component 2 and a transmission component 3.

[0045] Please see Figures 1 to 7As shown, the anti-winding component 2 is provided with multiple components located at the ends of the cutter shaft 13. The anti-winding component 2 includes a mounting plate 21 fixedly connected to the side wall of the gearbox 12. Multiple circumferentially distributed arc-shaped blades 22 are provided on the mounting plate 21. The arc-shaped blades 22 are matched with the rotation direction of the cutter shaft 13. A mounting groove 211 is provided on one side of the mounting plate 21. Multiple arc-shaped grooves 212 matching the arc-shaped blades 22 are provided in the mounting groove 211. The multiple arc-shaped blades 22 can slide along the arc-shaped grooves 212.

[0046] In this embodiment, the gearbox 12 of the rotary tiller body 1 is centrally located, and the anti-winding component 2 and the transmission component 3 are only provided on the two transmission sides of the gearbox 12.

[0047] Please see Figure 6 As shown, the arc-shaped blade 22 includes an inclined first cutting surface 221 and a horizontal second cutting surface 222. The shape of the second cutting surface 222 matches the connection of the cutter shaft 13, and there is a movable gap between the bottom surface of the arc-shaped blade 22 and the cutter shaft 13.

[0048] The transmission assembly 3 is provided with multiple components, which are respectively located in the corresponding mounting slots 211 and gearbox 12. It includes a connecting plate 31 that is slidably connected to the mounting slot 211. The gearbox 12 is provided with a transmission component 32, which can drive the connecting plate 31 to rotate and cause multiple arc-shaped blades 22 to slide along the arc-shaped slots 212.

[0049] The mounting plate 21 is coaxially arranged with the cutter shaft 13. The curvature of the arc groove 212 is consistent with the curvature of the arc blade 22, and the arc groove 212 allows the arc blade 22 to move radially along the cutter shaft 13.

[0050] The transmission assembly 3 also includes multiple connecting slots 311 formed on the connecting plate 31 and matching the arc-shaped slot 212. One end of the arc-shaped blade 22 is fixedly connected to a connecting post 33 inserted into the arc-shaped slot 212 and the connecting slot 311. A connecting pin 34 is fixedly connected to the side of the connecting plate 31 away from the mounting slot 211. Arc-shaped sliding grooves matching the connecting pin 34 are formed on the side wall of the gearbox 12 and the side wall of the support frame 11. The center of the arc-shaped sliding groove is consistent with the axis of the cutter shaft 13. The end of the connecting pin 34 away from the connecting plate 31 is fixedly connected to the transmission component 32.

[0051] Please see Figures 8 to 11 As shown, the transmission component 32 includes an oil reservoir 321 fixedly connected to the gearbox 12. The two ends of the oil reservoir cylinder are respectively sealed and slidably connected to a first piston rod 322 and a second piston rod 323. One end of the first piston rod 322 is fixedly connected to an electric push rod 324. The end of the second piston rod 323 is fixedly connected to a connecting cylinder. A connecting rod 325 is slidably connected inside the connecting cylinder. The end of the connecting rod 325 away from the connecting rod 325 is fixedly connected to a connecting pin 34.

[0052] Pressure sensors are installed on the inner walls of multiple oil storage tanks 321.

[0053] A control box is provided on one side of the support frame 11. The control box contains a control unit. Multiple electric push rods 324 and pressure sensors are respectively connected to the control unit by electrical signals. The control box can form a remote control connection or a direct control connection with the driving vehicle.

[0054] In use, the rotary tiller body 1 is connected to the drive vehicle via a universal joint. The drive vehicle provides power for the rotation of the cutter shaft 13. When the rotary tiller body 1 is performing land preparation, debris wraps around the cutter shaft 13 along the rotation direction. At the transmission end between the gearbox 12 and the cutter shaft 13, the second cutting edge 222 of the arc-shaped blade 22 can prevent debris from wrapping around the end of the cutter shaft 13, forming an isolation zone at the end of the cutter shaft 13. As a large amount of debris gradually accumulates at the end of the cutter shaft 13, since the wrapped debris always rotates with the cutter shaft 13 and has a tendency to contract radially, the first cutting edge 221 can cut the debris with the rotation of the cutter shaft 13.

[0055] For highly resilient debris such as tree roots and vines, the cutter shaft 13 will still become entangled. However, when a large amount of entangled material is entangled on the cutter shaft 13, the driver can activate the two electric push rods 324 simultaneously via remote control or direct control. The first piston rod 322 slides in the oil reservoir 321 and causes the second piston rod 323 to move the connecting rod 325. At this time, the connecting rod 325 drives the connecting column 33 and the connecting plate 31 to slide in the mounting groove 211. Multiple arc-shaped blades 22 unfold radially along the cutter shaft 13 under the action of the connecting plate 31, the connecting groove 311, and the arc-shaped groove 212. With the rotation of multiple first cutting surfaces 221 and the cutter shaft 13, the first cutting surfaces 221 can cut the tree roots or weeds wrapped around the anti-entanglement component 2.

[0056] It should be noted that, since the rotary tiller's cutter shaft 13 is arranged in a helical sub-shape, when multiple arc-shaped blades 22 are radially extended along the cutter shaft 13, some debris will enter below the second cutting surface 222. When the electric push rod 324 drives the arc-shaped blades 22 to reset, the second cutting surface 222, in conjunction with the cutter shaft 13, can cut the debris below the second cutting surface 222. After repeating the above actions, the isolation area at the end of the cutter shaft 13 is further expanded and the debris entanglement situation can be effectively improved.

[0057] In summary, through the anti-entanglement component 2, the arc-shaped blade 22, and the transmission component 3, the special structure of the arc-shaped blade 22 can form an isolation zone at the end of the cutter shaft 13 in the early stage of rotary tiller startup, preventing debris from damaging the connection between the gearbox 12 and the cutter shaft 13. In addition, when a large amount of debris is entangled at the end of the cutter shaft 13, the first cutting surface 221 can cut the high-speed rotating debris under the rotation of the cutter shaft 13, which can effectively improve the accumulation of debris on the cutter shaft 13.

[0058] In addition, for extremely tough tree roots and vines, although the curved blade 22 is difficult to effectively cut such debris in a stationary state, with the cooperation of transmission components 32 such as the oil tank 321, connecting plate 31 and electric push rod 324, multiple curved blades 22 can slide radially along the cutter shaft 13. At this time, the pressure between the first cutting surface 221 and the debris increases rapidly, and the debris is pulled and cut in this process. When the curved blade 22 returns to its original position, the second cutting surface 222 can cut the debris located below the second cutting surface 222. The cut debris is gradually detached from the cutter shaft 13 under the guidance of the curved surface of the curved blade 22, further improving the anti-entanglement effect of the cutter shaft 13 and preventing a large amount of debris from accumulating at the end of the cutter shaft 13.

[0059] Example 2

[0060] In practical use, it was found that when multiple curved blades 22 are reset, the cleaning effect of the second cutting surface 222 on the cutter shaft 13 is limited. This is not only due to the gap between the second cutting surface 222 and the cutter shaft 13, but also because some extremely tough debris is difficult to remove in one go through the second cutting surface 222. In addition, if the amount of debris accumulated below the second cutting surface 222 is large during the reset process of the curved blades 22, it is difficult to remove it all by cutting alone. Further improvements have been made based on the above embodiments.

[0061] Please see Figures 9 to 11 As shown, a transverse cutting component 4 is also provided between the anti-winding component 2 and the conveying component. When the pressure sensor exceeds the threshold during the radial contraction of the arc blade 22, the transverse cutting component 4 can make multiple arc blades 22 move horizontally back and forth.

[0062] The transverse cutting assembly 4 includes an arc-shaped tube 41. Multiple telescopic sleeves 42, which are matched with the arc-shaped blade 22, are connected to the side wall of the arc-shaped tube 41. The telescopic sleeves 42 are multi-stage telescopic. The end of the telescopic sleeve 42 away from the arc-shaped tube 41 is fixedly connected to the corresponding connecting post 33. An overflow pipe 43 is connected to one side of the oil storage tank 321. An overflow valve 44 is installed inside the overflow pipe 43. A piston plate 45 is slidably connected inside the overflow pipe 43. An elastic element 46 is installed between the piston plate 45 and the overflow pipe 43. The overflow pipe 43 is connected to the arc-shaped tube 41 through a pipe.

[0063] Both the arc-shaped pipe 41 and the overflow pipe 43 are filled with hydraulic oil.

[0064] The support frame 11 and gearbox 12 are both provided with connecting seats at the connection ends with the cutter shaft 13. The second cutting surface 222 has a stepped groove that matches the connecting seat. A third cutting surface 223 is provided on the vertical surface of the stepped groove. A connecting block 5 is provided on the bottom side of the second cutting surface 222 away from the cutter shaft 13. When the multiple arc-shaped blades 22 move horizontally, the connecting block 5 can push the winding material wrapped on the cutter shaft 13 to move to one side.

[0065] Based on the above embodiments, during use, when multiple arc-shaped blades 22 retract radially along the cutter shaft 13, the second cutting surface 222 cuts the entangled material located below it. During this process, the control unit determines whether the entangled material is completely cut based on the extension and retraction of the electric push rod 324 and the pressure peak value of the pressure sensor. If the pressure in the oil tank 321 exceeds the threshold during the reset process of the electric push rod 324, the overflow valve 44 will open and the hydraulic oil in the oil tank 321 will enter the overflow pipe 43. The piston plate 45 will be squeezed and the hydraulic oil on one side of the piston plate 45 will enter the annular pipe through the pipeline, causing multiple telescopic sleeves 42 to unfold synchronously, thereby causing multiple arc-shaped blades 22 to move laterally and horizontally, clearing the entangled material below the second cutting surface 222. During the lateral movement of the arc-shaped blades 22, the electric push rod 324 resets to the initial position.

[0066] The electric push rod 324 is restarted, and the hydraulic oil in the overflow pipe 43 and the annular pipe is reset under the action of the elastic element 46 and the piston plate 45. Multiple arc-shaped blades 22 are also reset. During this process, the third cutting surface 223 can cut off the debris at the connection between the cutter shaft 13 and the gearbox 12.

[0067] In summary, with the transverse cutting components 4 including the overflow pipe 43, the annular pipe, and the telescopic sleeve 42, when the arc-shaped blade 22 experiences incomplete cutting due to excessive toughness or excessive accumulation of the wrapped material below the second cutting surface 222 during radial retraction, the overflow valve 44 opens and the piston plate 45 inside the overflow pipe 43 slides. This causes multiple arc-shaped blades 22 to move laterally and, under the action of the connecting block 5, to push away the wrapped material. This avoids damage caused by hard contact between the arc-shaped blade 22 and the wrapped material, enabling the transmission component 3 to have a pressure overflow effect and allowing the arc-shaped blade 22 to push away the wrapped material at the end of the cutter shaft 13, ensuring an effective isolation zone is formed between the arc-shaped blade 22 and the end of the cutter shaft 13.

[0068] In addition, when the arc-shaped blade 22 is horizontally reset, the third cutting surface 223 can cut the entanglement on the side of the gearbox 12 connecting seat, further improving the cutting effect of the anti-entanglement component 2.

[0069] In another embodiment, the connecting block 5 is strip-shaped and the third cutting edge 223 is located on the vertical surface of the connecting block 5. The connecting block 5 is located on the vertical surface of the stepped groove and is elastically slidably connected to the stepped groove.

[0070] During the radial movement of the arc-shaped blade 22, the end of the connecting block 5 is always in contact with the blade shaft 13, which improves the effect of the connecting block 5 on the untangling of the entangled material when the arc-shaped blade 22 moves laterally.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
