Description

Technical Field

[0001] The present invention relates to the technical field of forestry land preparation equipment, and in particular to an integrated device for tilling and preparing soil for forestry planting. Background Art

[0002] A rotary tiller is a type of tilling 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, turning, breaking up, and mixing organic matter. When establishing a new forest, a rotary tiller can quickly remove surface weeds and residual roots, and turn the compacted soil below to the surface. Combined with organic fertilizer or humus, this improves soil aeration and fertility, providing a loose environment for the roots of seedlings.

[0003] When a rotary tiller is used for land preparation in a forest, the high density of tree roots, vines, and perennial weeds on the surface makes it very prone to blade entanglement. Furthermore, the blade shafts of existing rotary tillers mostly utilize a double-helix arrangement, which creates an eccentric load during rotation, resulting in the highest concentration of weeds at the blade connection end. This entanglement not only increases the blade shaft's rotational resistance and load, but also increases friction between the transmission oil seal and the rotating shaft. Prolonged exposure to this high friction condition can rapidly wear the seal lip, reducing its service life.

[0004] Chinese patent application number CN202210262539.9 discloses a blade shaft anti-weed entanglement device and a rotary tiller. This invention utilizes a cutting mechanism driven by a cylindrical cam to drive a horizontal blade in axial reciprocating motion on the blade shaft to cut. A tensioning rod of a tensioning mechanism, driven by a grooved cam to reciprocate radially relative to the blade shaft, pulls and cuts weeds entangled on the blade shaft. However, the cutting mechanism is relatively large, reducing the effective tilling area of the rotary tiller. Furthermore, while a first cover shields the cutting mechanism from weeds and other entangled objects, a clearance exists between the cover, the horizontal blade, and the blade shaft. This clearance can easily be breached by roots or vines entangled in the cutting mechanism, potentially damaging the cutting mechanism and the gearbox oil seal during continuous tillage. Furthermore, for resilient roots or vines, the horizontal blade, driven by a cam or other structure, can be easily damaged by hard contact during the cleaning process, such as when the cam rotates poorly or the connection between the horizontal blade and the cam breaks.

[0005] To this end, the present invention proposes an integrated device for tilling and preparing soil for forestry planting to solve the above problems. Summary of the Invention

[0021] 1. The present invention is equipped with an anti-winding component, an arc-shaped blade, and a transmission component. In the early stage of starting the rotary tiller, the special structure of the arc-shaped blade can form an isolation area at the end of the cutter shaft to prevent debris from damaging the connection between the gear box and the cutter shaft.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0042] Example 1

[0043] When a rotary tiller is used for land preparation in a forest farm, the high density of tree roots, vines, and perennial weeds on the ground makes it very easy for the tiller to become entangled in the blade shaft. Furthermore, since the rotary cutters are generally arranged in a staggered double helix pattern, entanglement at the blade shaft ends is particularly noticeable. When foreign matter becomes entangled in the blade shaft, it not only increases the rotational resistance and load on the blade shaft, but also increases the friction between the gearbox oil seal and the rotating shaft. Prolonged exposure to this high friction state causes rapid wear of the oil seal's sealing lip, thereby reducing the oil seal's service life. This embodiment is specifically designed to address the aforementioned issues.

[0044] See also Figures 1 to 11 As shown, an integrated device for tilling and leveling soil for forestry planting according to one embodiment of the present invention includes a rotary tiller body 1, which includes a support frame 11, a gear box 12, and a knife shaft 13 connected to the gear box 12, and also includes an anti-winding component 2 and a transmission component 3.

[0045] See also Figures 1 to 7As shown, the anti-winding component 2 is provided with multiple and respectively located at the ends of the knife shaft 13, the anti-winding component 2 includes a mounting plate 21 fixedly connected to the side wall of the gear box 12, and a plurality of circumferentially distributed arc blades 22 are provided on the mounting plate 21, and the arc blades 22 match the rotation direction of the knife shaft 13. A mounting groove 211 is provided on one side of the mounting plate 21, and a plurality of arc grooves 212 matching the arc blades 22 are provided in the mounting groove 211, and the plurality of arc blades 22 can slide along the arc groove 212.

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

[0047] See also Figure 6 As shown, the arc-shaped blade 22 includes an oblique first edge surface 221 and a horizontal second edge surface 222 . The shape of the second edge surface 222 matches the connection of the blade shaft 13 , and a movable gap is left between the bottom surface of the arc-shaped blade 22 and the blade shaft 13 .

[0048] The transmission assembly 3 is provided with multiple parts and is respectively located in the corresponding mounting grooves 211 and the gear box 12. It includes a connecting plate 31 that is slidably connected to the mounting groove 211. A transmission member 32 is provided in the gear box 12. The transmission member 32 can drive the connecting plate 31 to rotate and make the multiple arc blades 22 slide along the arc groove 212.

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

[0050] The transmission assembly 3 also includes a plurality of connecting grooves 311 opened on the connecting plate 31 and matching the arc groove 212. One end of the arc blade 22 is fixedly connected to a connecting column 33 inserted into the arc groove 212 and the connecting groove 311. A connecting pin 34 is fixedly connected to the side of the connecting plate 31 away from the mounting groove 211. An arc-shaped slide matching the connecting pin 34 is opened on the side wall of the gear box 12 and the side wall of the support frame 11. The center of the arc-shaped slide is consistent with the axis of the knife shaft 13. The end of the connecting pin 34 away from the connecting plate 31 is fixedly connected to the transmission member 32.

[0051] See also Figures 8 to 11 As shown, the transmission member 32 includes an oil storage tank 321 fixedly connected to the gear box 12, and the two ends of the oil storage cylinder are respectively sealed and slidably connected with the first piston rod 322 and the second piston rod 323, one end of the first piston rod 322 is fixedly connected to the electric push rod 324, and the end of the second piston rod 323 is fixedly connected to the connecting cylinder, and a connecting rod 325 is slidably connected in the connecting cylinder, and the end of the connecting rod 325 away from the connecting rod 325 is fixedly connected to the connecting pin 34.

[0052] The inner walls of the multiple oil storage tanks 321 are each provided with a pressure sensor.

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

[0054] During use, the rotary tiller body 1 is connected to the driving vehicle through a universal joint transmission, and the driving vehicle provides power for the rotation of the cutter shaft 13. When the rotary tiller body 1 performs land leveling operations, debris is wrapped around the cutter shaft 13 along the rotation direction of the cutter shaft 13. At the transmission end of the gear box 12 and the cutter shaft 13, the second edge surface 222 of the arc-shaped blade 22 can prevent debris from being wrapped around the end of the cutter shaft 13, so that an isolation area is formed at the end of the cutter shaft 13, and 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 shrink radially, the first edge surface 221 can cut the debris with the rotation cooperation of the cutter shaft 13.

[0055] For extremely tough debris such as tree roots and vines, the blade shaft 13 will still be entangled. However, when a large number of entanglements are entangled on the blade shaft 13, the driver starts the two electric push rods 324 at the same time through remote control or direct control, and the first piston rod 322 slides in the oil tank 321 and causes the second piston rod 323 to drive the connecting rod 325 to move. At this time, the connecting rod 325 drives the connecting column 33 and the connecting plate 31 to slide in the mounting groove 211. Driven by the connecting plate 31, the connecting groove 311 and the arc groove 212, the multiple arc-shaped blades 22 are expanded radially along the blade shaft 13. Under the rotation of the multiple first blade surfaces 221 and the blade shaft 13, the first blade surface 221 can cut the tree roots or weeds wrapped around the two sides of the anti-entanglement component.

[0056] It should be noted that since the blade shaft 13 of the rotary tiller adopts a spiral sub-type arrangement, when multiple curved blades 22 are radially expanded along the blade shaft 13, some debris will enter under the second blade surface 222. When the electric push rod 324 drives the curved blade 22 to reset, the second blade surface 222 cooperates with the blade shaft 13 to cut the debris under the second blade surface 222. After repeating the above actions, the isolation area at the end of the blade shaft 13 is further expanded and the entanglement of debris can be effectively improved.

[0057] To sum up, through the settings of the anti-winding component 2, the curved blade 22 and the transmission component 3, in the early stage of starting the rotary tiller, the special structure of the curved blade 22 can form an isolation area at the end of the cutter shaft 13 to prevent debris from damaging the connection between the gear box 12 and the cutter shaft 13. In addition, when a large amount of debris is entangled on the end of the cutter shaft 13, the first blade surface 221 can cut the high-speed rotating debris under the rotation cooperation of the cutter shaft 13, which can effectively improve the accumulation of debris on the cutter shaft 13.

[0058] In addition, for tree roots and vines with extremely strong toughness, although it is difficult for the curved blade 22 to effectively cut such debris in a stationary state, through the cooperation of transmission parts 32 such as the oil tank 321, the connecting plate 31 and the electric push rod 324, multiple curved blades 22 can slide radially along the cutter shaft 13. At this time, the pressure between the first blade surface 221 and the debris increases rapidly, and the debris is pulled and cut in this process. When the curved blade 22 is reset, the second blade surface 222 can cut the debris located below the second blade surface 222, and the cut debris gradually separates from the cutter shaft 13 under the guidance of the curved surface of the curved blade 22, further improving the anti-winding effect of the cutter shaft 13 and avoiding a large amount of debris gathering at the end of the cutter shaft 13.

[0059] Example 2

[0060] In actual use, it was found that when the multiple curved blades 22 were reset, the cleaning effect of the second cutting surface 222 on the blade shaft 13 was limited. This was not only due to the movable gap formed between the second cutting surface 222 and the blade shaft 13, but also because some extremely tough debris was difficult to be removed in one go by the second cutting surface 222. In addition, during the reset process of the curved blades 22, if a large amount of debris accumulated under the second cutting surface 222, it would be difficult to completely remove it by cutting alone. Further improvements were made based on the above embodiment.

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

[0062] The transverse cutting assembly 4 includes an arc tube 41, and a plurality of telescopic sleeves 42 matching the arc blade 22 are connected and arranged on the side wall of the arc tube 41. The telescopic sleeve 42 is multi-stage telescopic, and the end of the telescopic sleeve 42 away from the arc tube 41 is fixedly connected to the corresponding connecting column 33. An overflow pipe 43 is connected to one side of the oil storage tank 321, and an overflow valve 44 is provided in the overflow pipe 43. A piston plate 45 is sealed and slidably connected in the overflow pipe 43, and an elastic member 46 is provided between the piston plate 45 and the overflow pipe 43. The overflow pipe 43 is connected to the arc tube 41 through a pipeline.

[0063] The arc tube 41 and the overflow tube 43 are both filled with hydraulic oil.

[0064] The connecting ends of the support frame 11 and the gear box 12 and the cutter shaft 13 are all provided with connecting seats, the second blade surface 222 is provided with a stepped groove matching the connecting seat, the vertical surface of the stepped groove is provided with a third blade surface 223, and the bottom of the second blade surface 222 is provided with a connecting block 5 on the side 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 around the cutter shaft 13 to move to one side.

[0065] On the basis of the above embodiment, during use, when the multiple curved blades 22 shrink along the radial direction of the blade shaft 13, the second blade surface 222 cuts the winding material located below it. During this process, the control unit determines whether the winding material is completely cut off based on the extension and contraction amount of the electric push rod 324 and the pressure peak of the pressure sensor. If the pressure in the oil storage tank 321 exceeds the threshold during the resetting of the electric push rod 324, the overflow valve 44 will be opened and the hydraulic oil in the oil storage 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 tube through the pipeline, so that the multiple telescopic sleeves 42 will be expanded synchronously, and then the multiple curved blades 22 will move horizontally to push away the winding material below the second blade surface 22. During the lateral movement of the curved blade 22, the electric push rod 324 will be reset to its initial position.

[0066] The electric push rod 324 is started again, and the hydraulic oil in the overflow pipe 43 and the annular tube is reset under the action of the elastic member 46 and the piston plate 45, and the multiple arc-shaped blades 22 are also reset. In this process, the third blade surface 223 can cut off the debris at the connection between the knife shaft 13 and the gear box 12.

[0067] To sum up, through the setting of the transverse cutting components 4 such as the overflow pipe 43, the annular tube and the telescopic sleeve 42, when the arc blade 22 is incomplete in cutting due to the excessive toughness or excessive accumulation of the winding material below the second blade surface 222 during the radial contraction process, the overflow valve 44 opens and causes the piston plate 45 in the overflow pipe 43 to slide, causing multiple arc blades 22 to move laterally and push away the winding material under the action of the connecting block 5, avoiding damage caused by hard contact between the arc blade 22 and the winding material, so that the transmission component 3 has a pressure overflow effect, and enables the arc blade 22 to push away the winding material at the end of the knife shaft 13, ensuring that an effective isolation area is formed between the arc blade 22 and the end of the knife shaft 13.

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

[0069] In another embodiment, the connecting block 5 is strip-shaped and the third blade surface 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 , so that when the arc-shaped blade 22 moves laterally, the connecting block 5 improves the effect of removing the entangled objects.

[0071] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
