辽宁7卜一2播种机足我省农村1人播种机型,使用比较对通山1’制造上的缺陷和使用不当,会出如下一些故障。1.嗑种:①排种轮有缺陷。由于型孔加工粗糙,周边有棱角毛刺,型口倒角太小。为不损伤种子,顺利刮出型孔中多余的种子,在型孔后部做成圆弧形退种曲面,并用砂纸(布)抛光。②调整不当。刷种轮与排种轮间隙过大或过小,都应适当调整。调整的办法可更换胶套或在胶套里侧加纸垫。播大豆时其间隙为1毫米,播谷子为0.5毫米。播种高粱、玉米时采用刷种轮刷种,播大豆、谷子时应改用刷种刷。③种子本身缺陷。种子大小参差不齐,型孔内容纳的种子数不是设计的整倍数,必须进行筛选,去掉过大过小的种子。种子潮湿,坚实度降低,也易碎种,应播前晾晒。
Liaoning 7 Bu 2 sowing machine in rural areas of our province sowing models, the use of Tongshan 1 ’manufacturing defects and improper use, there will be some of the following failures. 1 kinds of species: ① seed wheel defective. As the rough hole processing, angular edges around the burr, chamfer too small. In order not to damage the seeds, the excess seeds in the holes are smoothly scraped off, and arc-shaped seeds are formed on the back of the holes and polished with sandpaper (cloth). ② improper adjustment. Brush seed wheel and seed wheel gap is too large or too small, should be properly adjusted. Adjust the method can change the rubber sleeve or in the rubber sleeve inside the paper pad. When sowing the gap is 1 mm, sowing 0.5 mm. Sowing sorghum, corn brush when the use of brush species, sowing, millet should be used instead of brush brush. ③ seed itself defect. The seed size varies, the number of seeds contained in the hole is not an integral multiple of the design, must be screened to remove the seeds is too large or too small. Seed moisture, reduce the degree of solidity, but also fragile species, should be sown before drying.
