COMBINED DEVICE FOR SURFACE CULTIVATION OF SOWING OR PLANTING CROPS

摘要

FIELD: agricultural engineering; garden and farming implements. SUBSTANCE: innovation of invention consists in mounting the detachable plates of ridge on upright of vertical knife; these detachable plates are provided with limiters to limit angle of turn in vertical plane about vertical axis of leading edge from 60 to 90 in way of reciprocating motion of device effected by means of handle connected with tube-holder and with rod of device. Beside that, ripper is made in form of rhomb provided with hinge horizontal self-sharpening and self-cleaning knives articulated on lower side of rhomb in slot of groove and protected with cover to avoid choking with soil; it is used as additional support for knives, thus ensuring stable operation of horizontal knives while device is reciprocating. Upper end of vertical upright of ripper is provided with mechanism for fixing angle of inclination relative to surface of soil by 10 to 15 by means of adjusting rectangular washer secured on upper end of ripper upright under rod. Seeding disk is provided with grooves or holes in peripheral portion; its cylindrical cover has rear end wall and circular projection-latch mounted at circular clearance relative to seeding disk with seed guide located in its upper portion and with funnel in lower portion; seeding tube of funnel is directed downward. EFFECT: enhanced efficiency. 4 cl
