我所试验场农机队全体职工,遵照伟大领袖毛主席关于“农业的根本出路在于机械化”的教导,在搞好现有农机具维修的同时,抽出一定力量,学习外地经验,自力更生,艰苦奋斗,开展了自动抽粪机的试制工作,经过20多次反复试验改进,于今年六月制成一台自动抽粪车:利用拖拉机发动机的进气系统,在空气滤清器后部稍加改装成作为抽气机,用0.4厘米厚的钢板加工了一个大粪罐,固定在专用的两轮拖车上(粪罐内装水肥1.7吨,加上自重部分,全重2吨半至3吨),只要将粪罐内的空气抽到真空度350度左右,即可利用大气压力, All the staff and workers of the pilot farm team in our trial field abide by the teachings of Chairman Mao, the great leader, on “the fundamental way out for agriculture lies in mechanization.” While doing a good job in maintaining existing farm machinery, we also took some strength and learned field experience to work hard, A trial of automatic pick-up manholes was carried out. After more than 20 repeated tests and improvements, an automatic pick-up truck was made in June this year. The air intake system of the tractor engine was slightly modified at the rear of the air cleaner into As a suction machine, a large manure tank was processed with a 0.4 cm thick steel plate and fixed on a special two-wheel trailer (manure tank containing 1.7 tons of water and fertilizer, plus weight part, 2 tons and a half to 3 tons) The air in the manure tank is pumped to the degree of vacuum about 350 degrees to make use of atmospheric pressure,
