Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, and in particular to a multifunctional sickle structure. Background Technology

[0002] The sickle is a historically significant and multifunctional agricultural tool, mainly composed of a blade and a wooden handle. Traditionally, sickles were primarily used for harvesting crops and cutting grass, making them relatively simple in function. When working in the field, they often required the use of other tools, which could make them cumbersome to carry.

[0003] Chinese Patent CN221748959U discloses a multi-functional sickle. It includes a handle, a blade, and a connecting tube assembly. The blade is connected to the connecting tube assembly. Its outer edge has sequentially connected cutting edges a, b, and c. Cutting edge a is arc-shaped and concave inwards. Cutting edge c includes a straight cutting edge a and an arc-shaped cutting edge a convex outwards. Cutting edge b is linearly inclined. This invention enables the blade to perform cutting, shoveling, hoeing, and chopping functions by connecting the handle to different positions.

[0004] However, the device still has shortcomings. When switching between different functions, the handle needs to be detached and then reconnected, which is cumbersome and can easily cause the handle to loosen and fall off. In addition, the positions and angles of each connector are fixed, which makes the angle between the handle and the sickle fixed and cannot be finely adjusted in actual operation.

Blades A101 and C103 are located on opposite sides of the knife body 1, with blade A101 being an arc-shaped sickle blade and blade B102 located at the end of the knife body 1 furthest from the fixing seat 2. The connecting seat 3 is connected to the fixing seat 2, and a splined shaft 6 is movably mounted on the connecting seat 3. A limiting assembly for limiting the rotation of the splined shaft 6 is also provided on the connecting seat 3. The limiting assembly includes a fixing post A4, a fixing post B5, and a spring A7. A slot is centrally located on the connecting seat 3. Fixing posts A4 and B5 are both located on the connecting seat 3, not on opposite sides of the slot. A limiting groove A41 is coaxial with fixing post A4. A toothed groove 51 is coaxial with fixing post B5 at the end furthest from fixing post A4. Both ends of the spline shaft 6 are inserted into the limiting groove A41 and the toothed groove 51, respectively, and are rotatably connected to both fixing posts A4 and B5. Button A61 and toothed block 62 are connected to both ends of the spline shaft 6, respectively. One end of button A61 is inserted into the limiting groove A41 and slides radially thereafter. Toothed block 62 is located within and meshes with toothed groove 51. Spring A7 is located within the limiting groove A41, with both ends abutting against the inner wall of the limiting groove A41 and the end face of button A61, respectively. One end of the outer tube 8 is connected to the spline shaft 6 and rotatably connected to the connecting seat 3 around the axis of the spline shaft 6. Several positioning holes 81 are equidistantly arranged radially on the outer tube 8. The inner rod 9 is a non-cylindrical rod, with a handle 10 at the end of the inner rod 9 furthest from the tool body 1. One end of the inner rod 9 is inserted into the outer tube 8 and slides radially therein. A groove 91 is provided on the inner rod 9, and a slide block 11 that slides axially within the groove 91 is provided. A positioning post 12 that penetrates the side wall of the inner rod 9 is provided on the slide block 11, and the positioning post 12 is inserted into the positioning hole 81 on the corresponding side. A spring rod 13 is provided on the inner wall of the groove 91, and the movable end of the spring rod 13 is connected to the slide block 11. A drive assembly is provided on the inner rod 9, and the drive assembly includes a slider A14, a push rod 16, a slider B17, and a spring B18. A limiting groove B92 is provided on the inner rod 9. A slider A14 is disposed within a sliding groove 91 and slides radially along the inner rod 9. A top plate 15 is provided on the side of slider A14 facing the slide block 11. A sloping groove 111 is provided on the side of slide block 11 facing slider A14. The top plate 15 is inserted into the sloping groove 111, and the bottom surface of the top plate 15 is in contact with the inclined surface of the sloping groove 111. A top rod 16 is located within the inner rod 9 and slides radially thereafter. Both ends of the top rod 16 are inserted into the sliding groove 91 and the limiting groove B92, respectively. Slider A14 is connected to the top rod 16. A slider B17 is slidably disposed within the limiting groove B92 and connected to the top rod 16. A button B171 is provided at the end of slider B17 away from the top rod 16, and the other end of button B171 extends outside the inner rod 9.Spring B18 is set in the limiting groove B92. The two ends of spring B18 abut against the side of slider B17 facing the top rod 16 and the inner wall of limiting groove B92, respectively. When the drive assembly is in working state, it drives the slide block 11 to slide and causes the positioning pin 12 to disengage from the positioning hole 81.

[0026] In this embodiment, during use, blade A101 is used to harvest, blade B102 is used to shovel or dig, and blade C is used to chop. When weeding is required, button A61 is pressed, which pushes the spline shaft 6 to slide, causing the toothed block 62 to disengage from the toothed groove 51. At this time, the angle between the outer tube 8 and the blade body 1 can be adjusted, aligning the blade body 1 and the outer tube 8 with a structure similar to a hoe. Then, button A61 is released, and under the tension of spring A7, button A61 slides back to its original position, retracting the toothed block 62 into the toothed groove 51, thereby locking the spline shaft 6. Both blades B102 and C103 can perform weeding or scraping actions. Based on this structure, it is often necessary to extend the length of the handle. At this time, press button B171. Button B171 pushes the top rod 16 to slide, and the top rod 16 pushes the slider A14 to slide, thereby causing the top plate 15 to be inserted into the inclined groove 111. At this time, the slide block 11 is squeezed by the top plate 15 and its inclined surface and slides adaptively, causing the positioning post 12 to automatically retract, thereby releasing the sliding limit between the inner rod 9 and the outer tube 8. Pull the inner rod 9 to the appropriate length and then release button B171. Then, pull the inner rod 9 slightly to make the positioning post 12 re-lock into the nearest positioning hole 81.

[0027] Example 2

[0028] like Figure 1 and Figure 2 As shown, the multifunctional sickle structure proposed in this utility model, compared with Embodiment 1, includes a bottle opener hole 105 and several hexagonal wrench holes 104 with different inner diameters.

[0029] In this embodiment, when working in the field, other tools may need to be repaired. However, it is inconvenient to carry repair tools (such as wrenches or sockets). In this case, the hexagonal wrench hole 104 on the tool body can be used to disassemble and assemble hexagonal bolts. The bottle opener hole 105 is used to assist in opening the bottle cap when needed, thus expanding the function of this device.
