我省种植玉米的地区,在玉米收割后,虽经多次耕翻,仍有带泥块的根茬留在地里,需要大批劳力拾茬、灭茬。为了解决这个问题,我所研制了水平旋转式玉米打茬机,于1980年通过地区级鉴定。该机作业质量好,玉米根茬的打碎率、灭净率都在85%以上。打茬后,土地疏松保墒好,碎茬还田提高了土壤肥力。该机主要由变速箱总成、机架、悬挂装置、传动装置、水平旋转刀总成和限深轮等组成(见图)。 In the area where corn is planted in our province, after the maize is harvested, the root stubble with mud remains in the ground after several times of tillage, which requires a lot of labor to pick up and stubble. In order to solve this problem, I developed a horizontal rotary corn stubble, in 1980 by the regional level appraisal. Machine good job quality, broken corn stubble rate, the net rate of over 85%. After stubble, the soil loose soil moisture, stubble back to improve soil fertility. The aircraft mainly by the gearbox assembly, rack, suspension, transmission, horizontal rotary knife assembly and limited depth wheel composition (see photo).
