The utility model provides an improved double-edged sickle, which comprises a hand-held rod and a sickle head. The hand-held rod is assembled at the bottom of the sickle head. The outer wall of the hand-held rod is distributed with anti-skid lines. The sickle head includes a U-shaped rod, an assembly block and a cutter body. The top two sides of the U-shaped rod are fixed with a regulating disc. The assembly block is located between two regulating discs, and the cutter body is distributed on both sides of the assembly block. The front and rear walls of the assembly block are provided with a rotating shaft, and the middle part of the regulating disk is provided with a shaft hole adapted to the rotating shaft. A washer is arranged between the rotating shaft and the shaft hole. The front and rear walls of the assembly block are provided with a stop block, which is located below the rotating shaft. The regulating disk is equidistantly distributed with a stop groove adapted to the stop block. The stop groove runs through the outer wall of the regulating disk and can be conveniently disassembled and assembled. It is easy to maintain and repair in the later period, and can adjust the position of the two cutters for different use needs. It can also improve the harvesting efficiency by using more conveniently.
【技术实现步骤摘要】
一种改良的双刃镰刀
本技术涉及农用镰刀,特别涉及一种改良的双刃镰刀。
技术介绍
目前大多数的农用镰刀大多只有单个刀体,在收割农作物时,效率比较低下,并且结构大多为一体,拆装不便,在磨损损坏后,维护维修繁琐,并且也不能调节刀体的位置,对于不同的使用者以及不同的使用需求,不能舒适的使用。
