中国在水稻种植面积和总产量方面位居世界第一，水稻产量在中国农业生产中占据非常重要的地位。在中国的主要粮食作物中，水稻生产技术最为繁杂，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.
原机手更换所有苗针，其中转箱上的小钥匙和凸轮键槽间隙过大，插植臂自由转动角度过大，虽然正确调整了苗针高度，但仍可能发生苗针卡在工作中并与苗顶碰撞。停止并关闭火源，从箱子中取出箱子，检查并清除箱口的所有杂物，然后重新装载原始箱子。
