Description

Technical Field

[0001] The utility model belongs to a sickle, and in particular relates to a lightweight portable sickle. Background Art

[0002] The sickle is a farm tool for harvesting crops and mowing grass in rural areas. It is mainly composed of a blade head and a main rod, and is widely used in rural areas. At present, the blade head and the main rod of the common sickles on the market are usually connected by welding or rivets, and the main rod adopts an integrally formed straight rod or curved rod. In order to improve the portability of the sickle, some sickle blade heads and the main rod on the market adopt a detachable or foldable connection method. Although the sickles on the market have achieved improved portability through the detachable or foldable connection between the blade head and the main rod, it is still not convenient to carry due to the long length of the main rod. In addition, in order to save more effort during harvesting and reduce the fatigue of the user's waist, the main rod is usually designed as a curved structure in the prior art. Specifically, the part of the main rod connected to the handle is bent upward and maintained at a certain angle with the cutting surface of the blade head. When using the sickle with this structure, the user can reduce the bending angle and can also achieve a smooth cutting of the roots of crops. However, the bending angle of the main rod of the existing sickle is fixed, and the bending angle of the main rod cannot be adjusted according to the user's usage habits and height.

The cutter head 1 includes a blade 11, a locking mechanism 12 and a fixing seat 13. The blade 11 and the locking mechanism 12 are detachably connected. The locking mechanism 12 is connected to the main rod 2 through the fixing seat 13. The main rod 2 includes an upper rod body 21, an angle adjustment mechanism 22 and a lower rod body 23. The angle adjustment mechanism 22 includes an upper connecting part 221, a bolt 222, a lower connecting part 223 and a nut 224. The upper rod body 21 and the lower rod body 23 are respectively connected to the upper connecting part 221 and the lower connecting part 223. The upper connecting part 221 and the lower connecting part 223 are connected by a bolt 222 and a nut 224.

[0024] The blade 11 of the utility model is detachably connected to the locking mechanism 12. The blade 11 can be quickly disassembled when carried, and the blade 11 can be quickly assembled on site when used, which takes up little space and has high disassembly and assembly efficiency, greatly improving the convenience and safety of carrying. At the same time, when the blade 11 is damaged, a new blade 11 can be quickly replaced, saving the cost of use; the main rod 2 can adjust the bending angle through the angle adjustment mechanism 22. When the bending angle of the main rod 2 needs to be adjusted, the nut 224 is loosened, and the upper connecting part 221 and the lower connecting part 223 are disconnected. After adjusting the bending angle of the upper rod body 21 and the lower rod body 23, the nut 224 is locked. At this time, the upper connecting part 221 and the lower connecting part 223 are tightly attached to each other, and the bending angle of the main rod 2 is fixed. The user can adjust the most comfortable angle according to the usage habits and height. The user's bending angle can be reduced during operation, which effectively reduces the fatigue of the user's waist and makes harvesting crops more time-saving and labor-saving. At the same time, the main rod 2 can also be disassembled and separated from the upper rod body 21 and the lower rod body 23 by removing the bolts 222 and the nuts 224, which has better portability.

[0025] Preferably, the upper connecting portion 221 and the lower connecting portion 223 are both provided with circumferentially arranged latching teeth 225 , and the latching teeth 225 on the two engage with each other.

[0026] When the bending angle of the main rod 2 needs to be adjusted, the nut 224 is loosened and the latching teeth 225 on the upper connecting portion 221 and the lower connecting portion 223 are disengaged. At this time, the upper rod body 21 and the lower rod body 23 can rotate around the bolt 222. After adjusting the bending angle of the upper rod body 21 and the lower rod body 23, the nut 224 is locked. At this time, the upper connecting portion 221 and the lower connecting portion 223 are tightly attached together, and the latching teeth 225 on the two engage with each other, thereby achieving the fixing of the bending angle of the main rod 2. The latching teeth 225 of the upper connecting portion 221 and the lower connecting portion 223 engage with each other, so that the bending angle of the main rod 2 is further locked and fixed, and the bending angle of the main rod 2 is prevented from changing when excessive force is applied.

[0027] Preferably, Figure 1 As shown, the upper rod body 21 and the lower rod body 23 are tubular and are provided with multiple groups of bamboo-shaped convex rings 24 on the outside. The upper rod body 21 and the lower rod body 23 are made of stainless steel, and the bamboo-shaped convex rings 24 are formed by stamping. By setting the bamboo-shaped convex rings 24, the deformation resistance of the upper rod body 21 and the lower rod body 23 is effectively improved. While meeting the structural strength requirements, the wall thickness of the upper rod body 21 and the lower rod body 23 can also be reduced, thereby reducing the overall weight of the main rod 2, achieving the purpose of saving materials and lightweight, and further improving the portability of the sickle.

[0028] Preferably, Figure 6As shown, the upper connecting part 221 and the lower connecting part 223 are respectively provided with a threaded head 226, and the upper rod body 21 and the lower rod body 23 are respectively provided with a threaded tube connected to the upper connecting part 221 and the threaded head 226 of the lower connection. The upper connecting part 221 and the lower connecting part 223 can be quickly disassembled and assembled through the above structure.

[0029] Preferably, as 2, Figure 3 , Figure 4 As shown, the tail of the blade 11 is provided with a first hook 111 and a second hook 112 with opposite opening directions, the locking mechanism 12 includes a sleeve 121, a hanging shaft 122, a hanging ring 124, a rotating shaft 125, and a rotating handle 126. The hanging shaft 122 is connected between the two side surfaces of the sleeve 121, and movable holes 123 are symmetrically provided on both side surfaces of the sleeve 121. The rotating handle 126 is movably connected to the sleeve 121 through the rotating shaft 125. One end of the hanging ring 124 is rotatably connected to the rotating handle 126, and the other end is hung in the movable hole 123. The tail of the blade 11 is inserted into the sleeve 121, the first hook 111 is hung on the hanging shaft 122, the second hook 112 is hung on the hanging ring 124, and the sleeve 121 is connected to the fixed seat 13.

[0030] The installation process of the blade 11: first, flip the rotating handle 126 counterclockwise, and the hanging ring 124 moves upward in the movable hole 123 during the flipping of the rotating handle 126. Then, insert the tail end of the blade 11 into the sleeve 121, so that the first hook 111 is hung on the hanging shaft 122, and the second hook 112 enters the lower position of the hanging ring 124. At this time, flip the rotating handle 126 clockwise, and the hanging ring 124 moves downward in the movable hole 123 during the flipping of the rotating handle 126. When the rotating handle 126 is flipped to the bottom, the hanging ring 124 is just hung in the second hook 112, and the second hook 112 is pulled down tightly to achieve locking, thereby achieving a locked and fixed connection between the blade 11 and the locking mechanism 12.

[0031] The disassembly process of the blade 11 is as follows: the rotating handle 126 is turned counterclockwise, and the hanging ring 124 moves upward in the movable hole 123 during the turning of the rotating handle 126, thereby disengaging from the second hook 112. At this time, the blade 11 is moved, and the first hook 111 is disengaged from the hanging shaft 122, and then the blade 11 is taken out of the sleeve 121.

[0032] like Figure 4 , Figure 5 As shown, a first mounting hole 127 is provided at the bottom of the jacket 121, a slot 131 is provided at the top of the fixing seat 13, and a second mounting hole 132 is provided on the side, the bottom of the jacket 121 is inserted into the slot 131, the first mounting hole 127 and the second mounting hole 132 are aligned, and the fixing seat 13 and the jacket 121 are fixed to the upper rod body 21 by rivets passing through the first mounting hole 127 and the second mounting hole 132.
