过去,我们曾用K—90铧式开沟犁开沟。由于我团土壤比阻大(1～1.2公斤/厘米~2),需要两台红旗—100牵引,沟深也只能达到70厘米,还留有沟堤,需大量人工清理。这种开沟机不能满足我地区农业生产的需要。所以,多年来大量的田间渠道仍以人工开挖为主。为了改变这种状况,我们遵照毛主席关于“农业的根本出路在于机械化”的伟大教导,从一九七二年开始着手第一台单圆盘旋转开沟机的研制工作。经过三次较大的改进,于一九七三年秋试制出第三轮样机。到一九七四年五月经再次改进后的样机已趋于完善,投入了生产试验(图1)。截至一九七五年八月,其中一台样机已完成开沟土方量为五万五千米~3,开
In the past, we used to furrow the furrow with the K-90. Due to the large mass resistivity (1 ~ 1.2 kg / cm ~ 2) in our regiment, we need two red flags of -100 traction. The depth of ditch can only reach 70 cm. There are ditches left, which requires a lot of manual cleaning. This trencher can not meet the needs of agricultural production in my area. Therefore, a large number of field channels over the years are still mainly manual excavation. In order to change this situation, we have followed the great teachings of Chairman Mao on “The fundamental way for agriculture lies in mechanization.” Since 1972, we have started the development of the first single-disc rotary ditching machine. After three major improvements, a third round of prototypes was produced in the fall of 1973. The prototype, which had been improved again in May 1974, has been refined and put into production tests (Figure 1). As of August 1975, one of the prototypes has completed ditching and earthwork of 55,000-300
