The invention relates to the agricultural industry, in particular, to the coulters seeders for sowing agricultural cultures. Single disc-anchor opener comprises a housing 1 with a mounting member 2 it to a leash, flat disk 3 is mounted at an angle to the direction of travel, semyatukonapravitel 4, anchor-lozheobrazovatel 5, the outer sidewall (6 and 7) which is formed as a vertical wall, a front portion 6, attached to the housing 1, concerning the disk 3 and the rear portion 7 reaches behind semyatukonapravitel 4 and connected to the housing 1 by means of spacers, the locking device 8 to change its installation and locking in the desired position. What is new is that the front portion 6 of the outer side wall is provided with a vertical groove 9 for entering therein the front end of the rear portion 7, while it is possible to change the distance L, from the longitudinal vertical plane passing through the center disk 3 to the end of the rear portion 7 the rear portion 7 is provided with the guide-stop 10, extending through an opening in the sidewall 7 and attached to the body 1 Spacer-fixing device 8 is provided with a damping element 11, providing its oscillation (in cross direction) near a position specified by the distance L. Furthermore, the joint 6, the front and rear parts of the outer sidewall 7-anchor lozheobrazovatelya 5 configured groove 9 filled with a porous elastic materialom- filler. The use of the claimed utility model for seeders and fertilizers will ensure reliable performance of a number of technological operations band sowing agricultural cultures and making granulated fertilizers to vary the seeding bandwidth (increase or decrease) in compliance with the requirements of the cultivation of specific agronomic crops, including in conditions of high soil moisture. 1 SP f BACKGROUND ZP 1 f ly-2 Fig.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к сошникам сеялок для посева с.-х. культур.
