PLOUGHSHARE Russian patent published in 2022 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural engineering, namely to devices for cutting furrows and seeding seeds. A ploughshare contains a case, two discs installed at an angle to each other on the case, a seed guider, and a ripper, made of a pipe of an ellipsoid cross-section as a single whole, while an upper part of the pipe is fixed with a bell to a funnel of a neck of the ploughshare case, and a seed speed damper. On a rear part of the ploughshare case, a device for seeding seeds is installed. In this case, the device for seeding seeds is made in the form of two separate spring pins. At the same time, one spring pin is made right, and the second spring pin is made left in a direction of movement of the ploughshare. In this case, the right spring pin is located on a right side of a furrow formed with the ploughshare, and the left spring pin is located on a left side of the furrow formed with the ploughshare. Axes of symmetry of right and left spring pins are inclined in a direction of movement of the ploughshare. Spring pins, in a lower part, are deflected towards an axial line of symmetry of a furrow bottom. Axes of symmetry of straight right and straight left rods of deflected part of spring pins are located in a horizontal plane. At the same time, the straight left rod of the left spring pin is located ahead the straight right rod of the right spring pin in a direction of movement of the ploughshare, while the straight right rod of the right spring pin overlaps the straight left rod of the left spring pin in a direction of movement of the ploughshare. Ends of straight right and straight left rods are behind the axial line of symmetry of the furrow bottom. At the same time, a gap at an output from straight right and straight left rods is equal to 30…35 mm. A rear part of the seed speed damper and the end of the straight right rod of the right spring pin lay in a transverse-vertical plane drawn relatively to the axis of symmetry of the furrow bottom. Spring pins are made of 65G spring steel.

EFFECT: invention will allow for an increase in uniformity of seed seeding without their shift relatively to a furrow.
