Description
技术领域technical field

背景技术Background technique
目前市面上的手推式的剪草机大多采用动力机器引擎,传动方式主要分为:滚刀式,旋刀式,甩刀式,甩绳式。这样的剪草机会产生较大的噪音,带来环境污染,特别是在办公和学习的地方,这种需动力引擎的剪草机就显得非常不受欢迎。由于动力引擎剪草机有动力装置,保养,维护费用较高;同时动力引擎剪草机主要依靠刀片的高速旋转把草排出,因此,对整机的安全性要求较高,操作时也会给工作人员带强烈的震动,长时间操作使人感觉不适。At present, most of the hand-push lawnmowers on the market use power machine engines, and the transmission methods are mainly divided into: hob type, rotary blade type, blade type, and rope type. Such lawnmowers will generate a lot of noise and cause environmental pollution, especially in offices and study places, such lawnmowers that require a power engine are very unpopular. Because the power engine lawnmower has a power device, the maintenance and maintenance costs are relatively high; at the same time, the power engine lawnmower mainly relies on the high-speed rotation of the blade to discharge the grass, so the safety requirements of the whole machine are higher, and the operation will also give Staff with strong vibration, long-term operation makes people feel uncomfortable.
拨禾轮包括普通拨禾轮、偏心拨禾轮、滚齿强制立式拨禾轮,普通拨禾轮结构简单,重量相对较轻,制造成本低,应用于割晒机及中小型联合收割机上,但其对倒伏作物的适应能力较差,对作物的打击严重。它由拨板、辐条、拉筋、轴和轴承、支臂及支杆等组成。工作时,拨禾轮相对机器作回转运动,拨板则起到拨禾、扶禾切割和拨送禾秆的作用。The reel includes ordinary reel, eccentric reel, and hobbing forced vertical reel. The ordinary reel has a simple structure, relatively light weight and low manufacturing cost, and is used in windrowers and small and medium-sized combine harvesters. , but its adaptability to lodging crops is poor, and it is a serious blow to crops. It consists of dials, spokes, ties, shafts and bearings, arms and rods. When working, the reel revolves relative to the machine, and the reel plays the role of reeling, cutting and feeding stalks.
往复式切割器的切割器传动机构可以采用空间型曲柄连杆机构的转向式型曲柄连杆机构。The cutter transmission mechanism of the reciprocating cutter can adopt the steering type crank connecting rod mechanism of the space type crank connecting rod mechanism.
