一桑田中耕除草机将12型手扶拖拉机犁刀轴两端加长,使犁刀伸到桑树枝下,便可扩大中耕除草面积。一般可使机耕面积扩大60％左右,功效提高近一倍。同时,加长犁刀,减少刀数,以利深耕和冬耕深翻。用这种中耕除草机进行桑田耕地和中耕除草,经几年实验、推广使用,效果较好。 (一) 旋耕机轴的改装主要将旋耕机轴两端电焊接长,右端(花键轴一端)电焊接长115mm,左端电焊接长106mm,直径30mm,在犁刀传动箱盖上开φ30mm孔,并配装自紧油封(30×52×10)及油封盖。油封盖用4只M8螺栓固定,并用开口销销住螺母,在左支臂上将轴承盖拆下,也配上自紧油封(30×52×10)及轴承盖。
A mulberry field cultivator weaver 12 type tractor Coulter shaft extended at both ends so that the coulter extends to the mulberry branches, we can expand the cultivation of weeding area. In general, the area of the plow can be expanded by about 60%, and its efficiency has nearly doubled. At the same time, lengthen the coulter, reduce the number of knives to facilitate deep plowing and winter plowing. With this cultivator cultivator mulberry cultivated land and cultivating weeds, after several years of experiments, to promote the use of better. (A) Rotary tiller axis modified rotary electric shaft is mainly welded on both ends of the long, right (spline shaft end) electric welding length 115mm, the left end of the electric welding length 106mm, diameter 30mm, the coulter gear box cover open φ30mm hole, and equipped with self-tight oil seal (30 × 52 × 10) and oil seal cover. Seal the oil cap with 4 M8 bolts and pin the nut with the open pin. Remove the bearing cap from the left arm and attach the self-tight oil seal (30 × 52 × 10) with the bearing cap.
