SOWING SECTION OF ANCHOR TYPE Russian patent published in 2015 - IPC A01C7/20 A01C5/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to the tools for planting crops. The sowing section of anchor type comprises a frame (2) with a bracket (1) rigidly attached to it and a hingedly attached flap (3). In the upper part of flap (3) at its outer side a flat spring (4) is rigidly attached. At the inner side of the flap (3) a rod (5) with a spring (6) is pivotally mounted. In the rear part of the flap (3) there are left and right ledges (14) bent down at an angle of 90°. The curvature lines of the ledges (14) are arranged at an acute angle to the direction of movement. The end (15) of the flap (3) is bent downwards at an acute angle relative to the horizontal. The upper end of the rod (5) is placed in the hole formed in the bracket (1). The upper end of the spring (6) is in contact with the bracket (1). The guide bar (7) with the anchor (8) placed in it is fixedly secured to the flap (3) below the hingedly attached rod (5). On the side of the upper part of the guide bar (7), a groove is made, on both sides of which the cheeks (10) are rigidly fixed, having two-armed lever (11) mounted between them. The lower end of the anchor (8) is closed with the stopper (9) and placed in the opening in the flap (3) and the opening at the end of the flat spring (4). The upper end of the anchor (8) is mounted in contact with fertiliser-drill tube (13) connected to the bracket (1). In the upper part the anchor (8) and the front end of two-armed lever (11) are pivotally connected in the cheeks (10). In the cheeks (10) the openings (12) radially formed. In the front end of the two-armed lever the opening is made coaxially with the openings (12).

EFFECT: constructive solution is aimed at improvement of the technological reliability of the process of sowing at increased soil moisture content and the presence in it of crop residues, as well as ease of the structure.
