MEANS FOR EXTENDING SERVICE LIFE OF SEED SPREADER Russian patent published in 2017 - IPC A01C5/00 A01C5/06 A01C7/20 

FIELD: agriculture.

SUBSTANCE: seed spreader for seed covering in the soil is made with the possibility to be connected to a sowing machine. The seed spreader comprises a flexible arm with a covering end. The flexible arm is made with the possibility to be connected to a seed chute having an issuing end of the sowing machine and displaces the covering end into the soil next to the seed chute of the sowing machine. The lower portion of the covering end of the flexible arm, pushing the seed into the soil, is made removable and is located adjacent to the issuing end of the seed chute, so that the lower portion of the covering end of the flexible arm is made replaceable. The invention implementation versions comprise a covering pusher portion having a stopper and a guide element for accommodating a removable means for extending the service life. Other implementation versions comprise a covering pusher portion engaging the rest of the spreader arm.

EFFECT: invention will extend the service life of a seed spreader due to the easy multiple replacing of a worn-out spreader portion in contact with the soil.
