Description

Technical Field

[0001] This utility model relates to the field of rotary tillage blade technology, and in particular to an anti-tangling rotary tillage blade for a miniature tiller. Background Technology

[0002] The rotary tiller blade is a core operating component designed specifically for small agricultural machinery. It is a key accessory for mini tillers and is usually made of high-strength alloy steel or manganese steel. It cuts, turns, and crushes the soil through high-speed rotation, making it an indispensable and efficient tool in modern small-plot agriculture.

[0003] In existing technologies, traditional rotary tillers mostly use straight or simply curved blades, which are directly fixed to the surface of the blade shaft by bolts or welding. During operation, when tilling wet soil, fields with abundant weeds, or fields with dense crop residues, weeds, crop stalks, and other easily entangled materials are easily rolled into the outer circumference of the blade shaft, forming entanglements. Especially under high-speed rotation, the entangled materials will continue to wrap around the surface of the blade shaft, causing a sudden increase in the load on the blade shaft and an increase in rotational resistance. This leads to a surge in power consumption, abnormal heat generation, and even malfunctions such as burning out the motor, which seriously restricts the operating efficiency and lifespan of mini tillers in complex fields.

[0004] Therefore, to address the problem of traditional rotary tillers' blade shafts easily becoming entangled and accumulating debris when used in fields with abundant weeds or dense crop residue, a mini tiller anti-entanglement rotary tiller blade has been designed. When using this anti-entanglement rotary tiller blade, the ends of each set of inclined blades are first connected to the corresponding connecting plate via a connecting mechanism. Then, a rigid connection between the inclined blades and the connecting mechanism is completed through an installation mechanism, forming an independent blade holder module. Subsequently, a fixing mechanism is used to axially fix the two blade holder modules to the blade shaft. During operation, the high-speed rotation of the blade shaft drives the inclined blade set to cut into the soil at a specific angle. Its cutting edge design effectively cuts easily entangled materials such as weeds and crop residues. The cut debris slides off along the inclined blade surface and is discharged. Combined with the three-dimensional cutting network formed by multiple symmetrically arranged inclined blades on both sides of the blade shaft, an active cutting mechanism for entangled materials is formed, avoiding the common entanglement and accumulation problem of traditional rotary tillers. The modular design allows for quick assembly and disassembly of individual inclined blade holders, adapting to different operational needs. Utility Model Content

[0005] Traditional rotary tillers typically use straight or simply curved blades that are directly fixed to the blade shaft by bolts or welding. Weeds, crop stalks, and other easily entangled materials can easily get caught on the outer circumference of the blade shaft, causing them to accumulate. Therefore, when used in fields with abundant weeds or dense crop residue, it is difficult to avoid the problem of debris entanglement and accumulation on the blade shaft of traditional rotary tillers.

[0006] The technical solution of this utility model is as follows: a micro tiller anti-tangling rotary tiller blade, including a blade shaft, with left-hand rotary tillers and right-hand rotary tillers evenly connected to the outer circumference of the blade shaft, and also including multiple sets of inclined blades.

Two sets of connecting plates are symmetrically arranged on the outer circumference of both sides of the blade shaft. The multiple sets of connecting plates are arranged one-to-one with the multiple sets of inclined blades. A connecting mechanism is provided between each set of inclined blades and the connecting plate on the same side. A fixing mechanism is provided through the two sets of connecting mechanisms. An installation mechanism is provided between each set of connecting mechanisms and the inclined blade on the same side.

[0007] Preferably, when using this type of anti-tangling rotary tiller blade, the ends of each set of inclined blades are first connected to the corresponding connecting plate through a connecting mechanism. Then, the inclined blades are rigidly connected to the connecting mechanism through an installation mechanism to form an independent blade holder module. Subsequently, the two sets of blade holder modules are axially fixed to the blade shaft through a fixing mechanism. During operation, the high-speed rotation of the blade shaft drives the inclined blade set to cut into the soil at a specific angle. Its blade design can effectively cut off easily tangled materials such as weeds and crop residues in the field. The cut debris slides off along the inclined blade surface and is discharged. Combined with the three-dimensional cutting network formed by multiple sets of inclined blades symmetrically arranged on both sides of the blade shaft, an active cutting mechanism for tangled materials is formed, avoiding the tangling and accumulation problems common in traditional rotary tillers. The modular design allows for quick assembly and disassembly of a single set of inclined blades to adapt to different operating scenarios.

[0008] Preferably, the connecting mechanism includes a fixed plate, a plug-in plate, and a plug-in groove. A fixed plate is provided between each set of connecting plates and the inclined blade on the same side. A plug-in plate is fixedly provided at the end of each set of inclined blades. A plug-in groove adapted to the plug-in plate is opened on the inclined end face of each set of fixed plates.

[0009] Preferably, the fixing plate is fixedly connected to the connecting plate on the same side, and the plug-in plate is engaged with the plug-in slot.

[0010] Preferably, the installation mechanism includes mounting bolts, mounting nuts, and mounting washers. Mounting holes are provided inside each set of plug-in plates and the same-side fixing plate. Mounting bolts are installed through each set of mounting holes. Mounting nuts are fitted onto the threaded ends of each set of mounting bolts. Mounting washers are provided between each set of mounting nuts and the outer wall of the same-side fixing plate.

[0011] Preferably, the mounting nut is threadedly connected to the mounting bolt, and the mounting washer is fitted onto the threaded end of the mounting bolt.

[0013] Preferably, the connecting nut and the connecting bolt are threaded together, and the connecting washer is fitted onto the threaded end of the connecting bolt.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using this type of anti-tangling rotary tiller blade, the end of each set of inclined blades is first connected to the corresponding connecting plate through a connecting mechanism. Then, the inclined blades are rigidly connected to the connecting mechanism through an installation mechanism to form an independent blade holder module. Subsequently, the two sets of blade holder modules are axially fixed to the blade shaft through a fixing mechanism. During operation, the high-speed rotation of the blade shaft drives the inclined blade set to cut into the soil at a specific angle. Its blade design can effectively cut off easily tangled materials such as weeds and crop residues in the field. The cut debris slides down and is discharged along the inclined blade surface. Combined with the three-dimensional cutting network formed by multiple sets of inclined blades symmetrically arranged on both sides of the blade shaft, an active cutting mechanism for tangled materials is formed, avoiding the common tangling and accumulation problem of traditional rotary tillers. The modular design allows for quick assembly and disassembly of a single set of inclined blades to adapt to different operating scenarios.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 and Figure 4 This utility model provides an embodiment: a micro tiller anti-tangling rotary tiller blade, including a blade shaft 1, with left-hand rotary tillers 2 and right-hand rotary tillers 3 evenly connected to the outer circumference of the blade shaft 1, and also including multiple sets of inclined blades 4. Two sets of inclined blades 4 are symmetrically arranged on the outer circumference of both sides of the blade shaft 1, and the two sets of inclined blades 4 are arranged in a circular array around the blade shaft 1. Two sets of connecting plates 5 are symmetrically arranged on the outer circumference of both sides of the blade shaft 1. The multiple sets of connecting plates 5 are arranged one-to-one with the multiple sets of inclined blades 4. A connecting mechanism is provided between each set of inclined blades 4 and the connecting plate 5 on the same side. A fixing mechanism is provided through the connection between the two sets of connecting mechanisms. An installation mechanism is provided between each set of connecting mechanisms and the inclined blade 4 on the same side.

[0026] Please see Figure 3 and Figure 5 The connecting mechanism includes a fixed plate 6, a plug-in plate 7, and a plug-in groove 8. A fixed plate 6 is provided between each set of connecting plates 5 and the inclined blade 4 on the same side. A plug-in plate 7 is fixedly provided at the end of each set of inclined blades 4. A plug-in groove 8 adapted to the plug-in plate 7 is opened on the inclined end face of each set of fixed plates 6. First, the plug-in plate 7 at the end of each set of inclined blades 4 is inserted into the plug-in groove 8 of the corresponding fixed plate 6 to form a snap-fit ​​connection. The fixed plate 6 is fixedly connected to the connecting plate 5 on the same side, and the plug-in plate 7 is snap-fit ​​connected to the plug-in groove 8. First, the plug-in plate 7 at the end of each set of inclined blades 4 is inserted into the plug-in groove 8 of the corresponding fixed plate 6 to snap-fit ​​connection.

[0027] Please see Figure 4 and Figure 5The installation mechanism includes mounting bolts 9, mounting nuts 10, and mounting washers 11. Each set of plug-in plates 7 has mounting holes inside both the interior and the interior of the same-side fixing plate 6. Mounting bolts 9 pass through each mounting hole, and mounting nuts 10 are fitted onto the threaded ends of each mounting bolt 9. Mounting washers 11 are placed between each mounting nut 10 and the outer wall of the same-side fixing plate 6. When the mounting holes are aligned, mounting bolts 9 are inserted, and mounting washers 11 are fitted in sequence, followed by tightening the mounting nuts 10, thus completing the rigid connection between the tilting blade 4 and the fixing plate 6, forming an independent blade holder module. Mounting nuts 10 are threadedly connected to mounting bolts 9, and mounting washers 11 are fitted onto the threaded ends of mounting bolts 9. When the mounting holes are aligned, mounting bolts 9 are inserted, and mounting washers 11 are fitted in sequence, followed by tightening the mounting nuts 10, thus completing the rigid connection between the tilting blade 4 and the fixing plate 6, forming an independent blade holder module.

[0028] Please see Figure 2 and Figure 5 The connecting mechanism includes connecting bolts 12, connecting nuts 13, and connecting washers 14. Each set of connecting plates 5 has connecting holes that penetrate into the interior of the cutter shaft 1. Each set of connecting holes has connecting bolts 12 that penetrate into the interior. Each set of connecting bolts 12 has a connecting nut 13 fitted onto the threaded end. Each set of connecting nuts 13 has a connecting washer 14 between it and the connecting plate 5 on the same side. Two sets of connecting plates 5 are symmetrically arranged on both sides of the cutter shaft 1. The two sets of connecting plates 5 on each side pass through the corresponding connecting holes of the cutter shaft 1 through connecting bolts 12. The connecting washer 14 and the connecting nut 13 work together to achieve axial fixation between the cutter holder module and the cutter shaft 1. The connecting nut 13 is threadedly connected to the connecting bolt 12. The connecting washer 14 is fitted onto the threaded end of the connecting bolt 12. Two sets of connecting plates 5 are symmetrically arranged on both sides of the cutter shaft 1. The two sets of connecting plates 5 on each side pass through the corresponding connecting holes of the cutter shaft 1 through connecting bolts 12. The connecting washer 14 and the connecting nut 13 work together to achieve axial fixation between the cutter holder module and the cutter shaft 1.

[0029] When using this type of anti-tangling rotary tiller blade, the working principle of the anti-tangling rotary tiller blade is as follows: When the blade shaft 1 rotates, it synchronously drives the left rotary tiller blade 2, the right rotary tiller blade 3 and the symmetrically distributed inclined blades 4 on both sides to carry out compound tillage. Among them, the left rotary tiller blade 2 and the right rotary tiller blade 3 perform conventional soil breaking operations, while the inclined blades 4 achieve the anti-tangling function through their unique inclined structure design.

[0030] The specific assembly process is as follows: First, insert the plug plate 7 at the end of each set of tilting blades 4 into the plug groove 8 of the corresponding fixing plate 6 to form a snap-fit ​​connection. At this time, the mounting holes on the inner walls of the two are automatically aligned. Then, insert the mounting bolt 9 and put on the mounting washer 11 in sequence, and tighten the mounting nut 10 to complete the rigid connection between the tilting blade 4 and the fixing plate 6, forming an independent blade holder module.

[0031] Two sets of connecting plates 5 are symmetrically arranged on both sides of the cutter shaft 1. The two sets of connecting plates 5 on each side pass through the corresponding connecting holes of the cutter shaft 1 through the connecting bolts 12, and are used in conjunction with the connecting washers 14 and connecting nuts 13 to achieve axial fixation between the tool holder module and the cutter shaft 1.

[0032] During operation, the high-speed rotation of the blade shaft 1 drives the four sets of tilting blades to cut into the soil at a specific angle. The blade design can effectively cut off easily entangled objects such as weeds and crop residues in the field. The cut debris slides off along the surface of the tilting blades 4 and is discharged. Combined with the three-dimensional cutting network formed by multiple sets of tilting blades 4 symmetrically arranged on both sides of the blade shaft 1, it forms an active cutting mechanism for entangled objects, avoiding the entanglement and accumulation problems common in traditional rotary tillers. The modular design allows for quick assembly and disassembly of a single set of tilting blades 4, adapting to the needs of different operating scenarios.

[0033] The tilting blades, with their four sets of tilting edges, create a dynamic cutting surface during rotation, actively cutting off tangled materials. This effectively solves the technical problem of traditional rotary tillers being prone to tangling, reduces downtime for cleaning, improves continuous operation efficiency, and significantly enhances anti-tangling performance.

[0034] The standardized design of the installation and connection mechanisms enables rapid and independent replacement of the four tilting cutter holders, reducing maintenance costs and time, and extending the service life of the equipment.

[0035] The engagement of the insertion slot 8 and the insertion plate 7 with the double fixing of the mounting bolt 9 ensures the impact resistance of the tool holder module under high-speed rotation conditions. The axial fixing method of the connecting bolt 12 passing through the tool shaft 1 strengthens the overall structure's torque resistance and ensures operational stability.

[0036] The coordinated operation of the left-hand rotary tiller 2, the right-hand rotary tiller 3, and the tilting blade 4 not only ensures the basic soil breaking effect, but also reduces the interference of entangled materials on the tillage depth through the anti-entanglement design, achieving a more uniform soil breaking effect.

[0037] The symmetrically distributed multi-set tilting blade design can adapt to different soil types and crop residue environments. By adjusting the tilt angle or replacing the blade holder module, it can meet diverse farming needs.

[0038] This design, through structural innovation and modular concepts, enhances anti-tangling performance while ensuring ease of maintenance and operational stability, providing technical support for the efficient and reliable operation of mini tillers.

[0039] Through the above steps, when using this type of anti-tangling rotary tiller blade, the ends of each set of tilting blades 4 are first connected to the corresponding connecting plate 5 through the connecting mechanism. Then, the tilting blades 4 are rigidly connected to the connecting mechanism through the installation mechanism to form an independent blade holder module. Subsequently, the two sets of blade holder modules are axially fixed to the blade shaft 1 through the fixing mechanism. During operation, the blade shaft 1 rotates at high speed, driving the set of tilting blades 4 to cut into the soil at a specific tilt angle. Its blade design can effectively cut off easily tangled objects such as weeds and crop residues in the field. The cut debris slides down and is discharged along the surface of the tilting blades 4. Combined with the three-dimensional cutting network formed by multiple sets of tilting blades 4 symmetrically arranged on both sides of the blade shaft 1, an active cutting mechanism for tangled objects is formed, avoiding the common tangling and accumulation problem of traditional rotary tillers. The modular design allows for quick disassembly and assembly of a single set of tilting blades 4, adapting to the needs of different operating scenarios.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
