РЕЗУЛЬТАТЫ ЭКСПЕРИМЕНТАЛЬНЫХ ИССЛЕДОВАНИЙ ПЛУГА-РЫХЛИТЕЛЯ В АГРЕГАТЕ С ТРАКТОРОМ ТЯГОВОГО КЛАССА 5

Abstract

The results of experimental studies of the machine-tractor unit (MTA), consisting of a tractor of traction class 5 K-744R and a mounted plow-ripper PBS-16 presented in the article. Determining the performance of the plow-ripper in the experiments was provided by changing the translational speed of the machine-tractor unit. Fuel consumption was recorded from the moment the unit entered the test plot at a steady speed and the unit left it. Experimental studies of the work of the MTA were carried out in the field conditions of the Marxovsky district of the Saratov region. Agrotechnical indicators were determined during the processing of fields on the stubble of chickpeas and millet. It has been established that the plow-ripper can be aggregated with tractors of traction class 5. The rational mode of operation of the plow with a working width of 6 m is ensured at a speed of 7.2-9.0 km/h and a working depth of 35 and 25 cm. unit operation was 3.6-4.5 ha/h, fuel consumption was 12.9-11.7 kg/ha. The unit provides a high degree of soil crumbling with a moisture content of 17-20% with the safety of stubble and plant residues on the agrobackground of millet up to 78%, on the agrobackground of chickpea up to 42%. Loosening the arable horizon up to 35 cm with mulching of the surface layer creates optimal conditions for the accumulation of moisture in the autumn-winter period. The movement of the MTA in the corral by the shuttle method, without the formation of dump and breakup furrows, provides a flat, ridgeless surface of arable land.
