随着我省机播面积的迅速扩大,播种机的需要量日趋增多,除省、地安排的产品外,不少县、社厂也开始生产与泰山—25或泰山—12拖拉机配套的悬挂谷物联合播种机。但是目前由于缺乏用于排种盒的薄钢板,排种机构加工工艺复杂,给生产厂,尤其是给县、社厂带来不少困难。为解决这个问题,一九七三年桓台县塑料厂和县农机所就开始试验用塑料代钢制造排种器的零部件,取得了一定成绩。一九七七年又
With the rapid expansion of machine-sowing area in our province, the demand for planters is on the rise. In addition to the products arranged by provinces and cities, many counties and community-based factories have also started to produce hanging grains for Taishan-25 or Taishan-12 tractors Joint planter. However, due to the lack of thin steel plates used for seed-setting boxes, the complicated processing technology of the seed-arranging mechanism brings many difficulties to the production plants, especially to the counties and social factories. In order to solve this problem, in 1973, Huantai Plastic Factory and County Agricultural Machinery Factory started to experiment with the manufacture of parts made of plastic on steel gauges, and achieved some success. In 1977 and again
