Abstract

FIELD: agricultural implements. SUBSTANCE: earth slot-cutter has vertically mounted knife, bar point at its lower part and deformers on its side surfaces for compaction of slot walls. Knife is made in the form of equilateral triangle with double-face blades at its sides. Mounting holes are located over length of knife and at crossing of triangle medians at equal pitch. Bar point is seated in one of peripheral holes at point where at point where conjugating blades are crossing in working position. Made in side surfaces of knife are equal-size circular grooves which in their cross-section have the form of unequal-sides trapezium with centers coincided with axes of mounting holes. Deformers are made as pairs of equal-size spherical disks which are directed with their concavities towards the side surfaces of knife and seated by their peripheral edges in circular grooves. Deformers are connected to each other and to upright by bolt fitted in one of knife mounting holes and in shells of central holes in spherical disks. EFFECT: high efficiency. 1 cl, 18 dwg

Scope: agricultural engineering, in particular a device for making cracks. The inventive slider contains a vertically mounted knife, a chisel in the lower section and the deformers on the side surfaces to seal the walls of the slit. The knife is made in the form of an equilateral triangle with dihedral blades on its sides. Mounting holes are made with equal pitch along the length and at the intersection of the medians of the triangle. In one of the peripheral holes at the intersection of the mating blades in the working position, a bit is placed. On the side surfaces of the knife, different-sized annular grooves are made in cross section in the form of an unequal trapezoid with centers aligned with the axes of the mounting holes. The deformers are made in the form of pairs of different-sized spherical disks, facing concavities towards the side surfaces of the knife and placed peripheral edges in the annular grooves. The deformers are connected to each other and the rack by a bolt placed in one of the mounting holes of the knife and inserts in the central holes of the spherical disks.
