我国水稻种植面积和水稻总产量均居世界第一，水稻生产在我国农业生产中占有十分重要的地位。我国主要粮食作物中，水稻生产技术最杂乱、季节性最强、劳动强度最大，而水稻种植是水稻生产中最重要的环节。
For many years, China has been dominated by artificial seedling planting, and broad farmers are urgently demanding to be liberated from this heavy manual labor. The products of rice transplanter produced and used in China can be divided into two types: one wheel riding, four-wheel riding and walking. During the production and sales volume of the single-wheel rice-transplanter and the largest holding capacity, the walking rice transplanter second, four-wheel rice-transplanter less.
People cannot leave agricultural production, the use of agricultural machinery is also more and more extensive. When the rice transplanter is working, if the interpolation part of the machine is not working and there is continuous noise, the fault can be basically judged as the seedling needle hitting the seedling mouth. Still can’t solve the problem after adjusting.
原机手动更换所有秧针，其中回转箱上的小键与凸轮键槽间隙太大，插植臂自由回转角度太大，即使正确调整秧针高度，仍然会发生秧针在工作中并取苗顶端进行碰撞。停止并关火，将板条箱从板条箱中取出，检查并清除板条箱口内的所有杂物，并重新装入原板条夹。
