FIELD: agriculture. ^ SUBSTANCE: device comprises a rectangular welded frame with hitch systems, fixtures of working bodies and the working bodies. The working bodies consist of racks of bits, and arched semihoes with a cut in the back part are hinged to them. The device has a capacity with a relief valve that is connected to the tractor compressor with air lines, and with working routes through the collector and the diaphragm dosing device to the pipeline of fertilisers supply, located on the rack. The arched semihoes and bits have interchangeable plates with cutting edges and are connected with them by means of threaded connections with the possibility of formation the gap between the bit and the plate. ^ EFFECT: design concept enables to expand the functionality of the device, increase operational reliability, reduce energy consumption of the process, reduce the application rate of fertiliser application while increasing the efficiency of its use, improve the quality of cultivated surface of soil. ^ 7 dwg |
