[0026] Example 1

[0027] like Figure 1-5 As shown, the present invention proposes an agricultural knife structure, including a blade 2, an axe blade 3, and a connecting component 4;

[0028] The blade 2 has a first double-edged blade 5 extending to the other end at the lower part of one end, and a handle 1 away from the first double-edged blade 5 at the other end of the blade 2. The handle 1 is integrally formed with the blade 2, and notches 7 are provided on both sides of the handle 1. The two notches 7 are symmetrically arranged according to the middle of the handle 1, which makes it more comfortable to use when changing the upper and lower parts of the handle 1.

[0029] The axe 3 is mounted on the upper part of the blade 2;

[0030] The connecting component 4 is detachably mounted on the end of the blade 2 and located at one end of the first double-edged blade 5. When the axe 3 is chopping and retracting with the axe blade 10, the connecting component 4 can be separated from the blade 2 and the extension 6 can be disassembled to avoid the extension 6 obstructing the chopping and retracting of the axe 3. One end of the connecting component 4 is provided with an extension 6 for extending the blade 2 and adjusting the way the blade 2 is used in use. In use, an accessory matching the axe 3 (not shown in the figure) can be provided on the upper part of the extension 6 to support the extension 6 when the blade 2 drives the extension 6 to chop, thereby reducing the stress on the connecting component 4 and increasing the service life of the connecting component 4.

[0031] In this embodiment, the handle 1 is held by the notch 7, which allows the handle 1 to swing the blade 2 to harvest the sugarcane using the first double-edged blade 5. The handle 1 is then held in the opposite direction, which allows the blade 2 to drive the axe 3 to harvest the sugarcane using the axe blade 10 at a low position. The extension 6 is installed at the end of the blade 2 through the connecting component 4, which extends the length of the blade 2. This allows the blade 2 and the extension 6 to harvest the sugarcane simultaneously, enabling high-level harvesting and making the harvesting of sugarcane more convenient.

[0032] Example 2

[0033] like Figure 1-4 As shown, the present invention proposes an agricultural knife structure. Compared with Embodiment 1, the difference in this embodiment is that the projected shape of the axe 3 is trapezoidal, the upper length of the axe 3 is greater than the lower length, the upper part of the axe 3 is provided with an axe blade 10, and the lower part of the axe 3 is connected to the upper part of the blade 2 at one end. The axe 3 and the blade 2 are integrally formed.

[0034] In an optional embodiment, a second double-edged blade 9 is provided at the lower part of the extension 6. The end face size of one end of the extension 6 is the same as the end face size of one end of the blade 2, and the second double-edged blade 9 is arranged to be adapted to the size of the axe blade 10.

[0035] In this embodiment, the axe 3 is installed on the upper part of the blade 2, making the thickness of the axe 3 and the cutting edge angle of the axe blade 10 larger. This allows the axe 3 to cut harder objects through the axe blade 10, improving the chopping efficiency. Furthermore, the second double-sided blade 9 is arranged in a size-matched manner with the axe blade 10, making the gap between the blade 2 and the extension 6 close to the minimum value. This reduces the possibility of jamming between the blade 2 and the extension 6 when the blade 2 drives the extension 6 to perform chopping work.

[0036] Example 3

[0037] like Figure 5 As shown, the present invention proposes an agricultural knife structure. Compared with the first embodiment, the difference in this embodiment is that the connecting component 4 includes a first mounting plate 41, a second mounting plate 42, a snap ring 43, and a limiting post 45.

[0038] The first mounting plate 41 and the second mounting plate 42 are respectively mounted on both sides of the extension 6 and are arranged flush with the upper part of the extension 6. The thickness of the first mounting plate 41 is greater than the thickness of the second mounting plate 42, and the second mounting plate 42 is flexible.

[0039] The number of limiting posts 45 is at least two. Both limiting posts 45 are installed on the side of the second mounting plate 42, and one end of each post passes through the blade 2 and the first mounting plate 41 and is inserted into the blade 2 and the first mounting plate 41.

[0040] The retaining ring 43 is installed at the end of the limiting post 45 and connected to the first mounting plate 41. The retaining ring 43 and the limiting post 45 are arranged in a one-to-one correspondence.

[0041] In an optional embodiment, both the blade 2 and the first mounting plate 41 are provided with a plurality of mounting holes 8 at one end. When the limiting post 45 is installed in conjunction with the blade 2 and the first mounting plate 41, one end of the limiting post 45 is installed inside the mounting hole 8.

[0042] In this embodiment, the first mounting plate 41 and the second mounting plate 42 are mounted on both sides of the extension 6. A limiting post 45 is provided on the side of the second mounting plate 42 and located between the first mounting plate 41 and the second mounting plate 42, which is inserted into the first mounting plate 41. At the same time, the second mounting plate 42 is bent and the blade 2 is inserted between the first mounting plate 41 and the second mounting plate 42, so that the limiting post 45 is inserted into the mounting hole 8 of the blade 2 and the first mounting plate 41, connecting the extension 6 to the blade 2, making the disassembly and assembly of the extension 6 more convenient.

[0043] Example 4

[0044] like Figure 5 As shown, the present invention proposes an agricultural knife structure. Compared with the first embodiment, the difference is that the width of the first mounting plate 41 and the second mounting plate 42 is smaller than the width of the blade 2 and the extension 6, and the upper and lower parts of the first mounting plate 41 and the second mounting plate 42 are provided with chamfers 47.

[0045] In this embodiment, the first mounting plate 41 and the second mounting plate 42 are flush with the upper part of the extension 6, and the width of the first mounting plate 41 and the second mounting plate 42 is smaller than the width of the blade 2 and the extension 6. By setting chamfers 47 on the upper and lower parts of the first mounting plate 41 and the second mounting plate 42, the first mounting plate 41 and the second mounting plate 42 are in excessive contact with the sugarcane during the harvesting process, reducing resistance and improving the smoothness of cutting.

[0046] Example 5

[0047] like Figure 5 As shown, the present invention proposes an agricultural knife structure. Compared with the first embodiment, the difference is that a mounting groove 44 is provided on one side of the first mounting plate 41, the mounting hole 8 is located inside the mounting groove 44, and the multiple mounting holes 8 are arranged at equal angles according to the center of the connecting component 4.

[0048] In an optional embodiment, a slot 46 is provided on the outer side of the limiting post 45 and near the top, and the retaining spring 43 is engaged inside the slot 46 and connected to the bottom end of the mounting groove 44, wherein the spacing between the multiple limiting posts 45 is greater than the size required for the installation of the retaining spring 43.

[0049] In this embodiment, by providing an installation groove 44 on the side of the first mounting plate 41, the end of the limiting post 45 and the retaining spring 43 are both located inside the installation groove 44, and the retaining spring 43 is engaged in the retaining groove 46 and connected to the bottom of the installation groove 44. This ensures that the connection between the first mounting plate 41 and the second mounting plate 42 through the limiting post 45 is relatively stable, and avoids the end of the limiting post 45 from being located on the side of the first mounting plate 41 and contacting the sugarcane, thus reducing obstacles during harvesting.

[0050] In this invention, the notch 7 allows the handle 1 to be held in both forward and reverse positions. Holding the handle 1 forward allows the blade 2 to be swung, using the first double-edged blade 5 to chop sugarcane at a low position. Simultaneously, holding the handle 1 in reverse and swinging the blade 2 causes the blade 2 to drive the axe 3, using the axe blade 10 to chop sugarcane at a low position and to cut harder objects, preventing damage to the first double-edged blade 5 and increasing the tool's applicability. Furthermore, by bending the second mounting plate 42, the blade 2 moves between the first mounting plate 41 and the second mounting plate 42, positioning the limiting post 45 below the mounting hole 8. The springback of mounting plate 42 causes the limiting post 45 to insert into the mounting holes 8 on the first mounting plate 41 and the blade 2, connecting the blade 2 to the extension 6. The retaining spring 43 is then engaged in the retaining groove 46 inside the mounting groove 44, ensuring a stable connection between the first mounting plate 41 and the second mounting plate 42, and a relatively stable connection between the blade 2 and the extension 6. The blade 2 then drives the extension 6 to perform the cutting and finishing work through the cooperation of the first double-edged blade 5 and the second double-edged blade 9. Simultaneously, the angle of the extension 6 can be adjusted through the cooperation of the limiting post 45 and the mounting hole 8, so that the extension 6 and the blade 2 are placed at a right angle. Figure 3 As shown, the blade 2 and the extension 6 are used in a sickle shape to increase the applicability of the knife.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
