Description

Technical Field

[0001] This utility model relates to the field of rotary tillage equipment technology, and more specifically, to a rotary tillage blade and a rotary tillage shaft. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] A rotary tiller is a soil tillage implement pulled and driven by a tractor. Its core function is to complete multiple tasks such as plowing, harrowing, and leveling. The purpose is to make the soil fine, flat, and loose, so that the roots and stems of the previous crop, weeds, fertilizers, or pesticides can be mixed into the soil. This creates a good seedbed for seed germination and crop growth, and improves the effectiveness of fertilizers and pesticides. Compared with the traditional separate operations of plowing and harrowing, the rotary tiller completes the work in one go, thus improving work efficiency.

[0004] The rotary tiller shaft, as the main working component of the rotary tiller, is connected to the tractor's power output shaft via a drive shaft. Various shaped blades are installed on the rotary tiller shaft. The rotation of the rotary tiller shaft drives the blades to move, causing the rotating blades to cut into the soil at a certain angle, thereby achieving the tilling and harrowing of the soil.

[0005] Traditional rotary tillers are mostly L-shaped or curved blades. Their blades typically consist of a support at one end and a curved section at a specific angle at the front. The inner side of the curved section is sharpened to form a tangential edge. In actual rotary tillage, the soil is tilled and leveled through "hooking, tearing, and throwing." However, in actual use, the above-mentioned technology has the following drawbacks: During rotary tillage, the curved edge of the blade first contacts the grass roots. Because the blade is rotating at high speed at this time, its curved shape easily hooks or entangles the grass roots. At the same time, since the grass roots are deeply embedded in the soil and have great tensile strength, the blade applies a huge pulling force to the grass roots. This force is not enough to cut the grass roots, but rather to pull them out of the soil or tear them apart by the roots. As a result, weeds cannot be effectively removed. Many of the pulled-out weeds are not dead, and their roots or stems can easily regrow and survive after contact with the soil, making it impossible to effectively eliminate weeds and thus affecting the growth of subsequent crops. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a rotary tiller and rotary tiller shaft that can effectively cut grass roots below the ground surface, eliminate weeds, and improve the quality of subsequent crop growth.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] On the one hand, this utility model provides a rotary tillage tool.

[0009] A rotary tiller includes a blade body, which includes a mounting portion and a cutting portion. The mounting portion is horizontally and linearly arranged. The cutting portion is located at one end of the mounting portion. A first cutting edge is provided on one side of the cutting portion. The first cutting edge is arc-shaped, and its convex surface faces away from the mounting portion. A first cutting portion is provided on the side of the cutting portion away from the mounting portion. The first cutting portion is arc-shaped, and its end away from the cutting portion is inclined upward.

[0010] In some possible embodiments, a second cutting portion is provided at a section of the cutting portion away from the mounting portion. The horizontal plane of the second cutting portion is flush with the tool body. The end of the second cutting portion away from the cutting portion is set as a pointed tip. A second cutting edge is provided on the outer edge of the second cutting portion. One end of the second cutting edge communicates with the first cutting edge, and the other end extends to the first cutting portion.

[0011] In some possible embodiments, one side of the first cutting part is provided with a third cutting edge, one end of the third cutting edge is connected to the second cutting edge, the extension direction of the third cutting edge is consistent with the extension direction of the first cutting part, the inclination angle of the first cutting part is set to 30°-45°, and a soil breaking part is provided at the end of the first cutting part away from the cutting edge, the extension direction of the soil breaking part is consistent with the end of the first cutting part away from the cutting edge.

[0012] In some possible embodiments, the end of the soil-breaking part away from the first cutting part is provided with a first soil-breaking surface, a second soil-breaking surface and a third soil-breaking surface. The second soil-breaking surface is horizontally arranged. One end of the first soil-breaking surface is connected to the end of the third cutting edge away from the second cutting part, and the other end is connected to the second soil-breaking surface. The third soil-breaking surface is inclined. One end of the third soil-breaking surface is connected to the second soil-breaking surface, and the other end is connected to the side of the first cutting part away from the third cutting edge.

[0013] In some possible embodiments, a third cutting portion is provided on the side of the cutting portion that is inclined away from the first cutting portion. The third cutting portion is vertically arranged and gradually narrows in the vertical direction away from the cutting portion.

[0014] In some possible embodiments, the third cutting portion has a fourth cutting edge on the vertical sidewall near the first cutting edge.

[0015] In some possible embodiments, the mounting part has mounting holes and mounting grooves, the mounting grooves being arc-shaped grooves, and two mounting holes, which are located at opposite ends of the mounting groove along the length of the mounting part.

[0016] On the other hand, this utility model also provides a rotary tillage shaft.

[0017] A rotary tiller includes a shaft body on which a plurality of rotary tiller blades as described above are disposed.

[0018] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0019] 1. By setting arc-shaped first, second, and third cutting edges, these edges are interconnected to form a continuous cutting edge, which can quickly and accurately cut grass roots below the ground during rotary tillage, avoiding the problem of traditional blades snagging or tearing grass roots. This effectively prevents weeds from regrowing and improves the quality of subsequent crop growth. The arc-shaped blade design enhances the smoothness of cutting, ensures that grass roots are completely separated, and reduces weed residue.

[0020] 2. The first cutting section is set in an arc shape and tilted upward. This structure reduces the resistance when the blade enters the soil, making the cutting action smoother and more efficient. At the same time, it promotes the fine fragmentation and uniform mixing of the soil. The setting of the soil breaking section further enhances the soil breaking ability. At the same time, it increases the depth of cultivation, making the cultivated soil looser and flatter, creating an excellent seedbed environment for seed germination and crop growth, and improving the overall cultivation effect.

[0021] 3. The mounting section adopts a horizontal straight line design and has an arc-shaped mounting groove and two mounting holes. The symmetrical distribution provides a more secure fixing method, effectively reducing the risk of vibration and loosening during high-speed rotation. This not only extends the service life of the blades but also ensures the continuity and reliability of the tillage process, reducing the frequency of maintenance and the possibility of work interruption.

[0022] 4. By setting up a vertical third cutting section and its fourth cutting edge, as well as multiple soil-breaking surfaces of the soil-breaking section, the blade can simultaneously perform cutting and soil-breaking operations in horizontal, vertical and inclined directions, enhancing the comprehensiveness of soil treatment and weed removal. The multi-angle design improves the adaptability and working efficiency of the blade, ensuring uniform and thorough tillage under different soil conditions. Attached Figure Description
