DISC-ANCHOR PLOUGHSHARE Russian patent published in 2011 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: invention refers to the sphere of agricultural engineering industry. A ploughshare comprises a body 1, which is rigidly connected to a leash 2, a flat disc 3, installed at the angle to direction of motion, a seed and fertiliser guide 4, a scraper-anchor-scraper bar 5 and a furrow-closing hoe 15. The body 1 of the ploughshare is equipped with a mechanism to control pressure and position of the ploughshare relative to the frame 6, which consists of press springs 11 and press rods 12. Springs 11 and rods 12 are arranged with the possibility to vary length of their working part and to change their position in vertical direction. At the same time the mechanism to control pressure and position of the ploughshare is installed between the leash 2 and the stop 8, which are connected to the frame 6 by means of a bracket 7. A furrow-closing hoe 15 arranged as a double-horn bracket is fixed hingedly to the rear part of the ploughshare body 1. At the bracket ends there are symmetrically fixed soul guides 16 installed at the angle of 20-25 degrees towards the motion. The distance between free ends of soil guides 16 is close to the distance between the end of the scraper-anchor-scraper bar 5 and the disc 3.

EFFECT: invention will make it possible to carry out a strip sowing in a high-quality manner with observation of the specified depth of seeds closing along the whole width of the device grip within optimal agrotechnical time with soil moisture up to 35%.
