MULTI-PURPOSE CHISEL FOR SOIL TREATMENT IN VINEYARDS

Used in Russia mechanized technology in the vineyards characterized by an increase in en-ergy costs 2.5–3.4 times compared to foreign countries. Most of the energy costs account for processing vineyard soil. It is necessary to improve the methods of mechanized soil cul-tivation in vineyards in terms of reducing en-ergy consumption while maintaining quality. The aim of the study is to develop mecha-nized universal technical means and working bodies for processing row-spacing of vine-yards with the lowest energy consumption without damaging the root system of the bushes. The designed multioperational chisel is capable of performing tiered tillage in ac-cordance with the architectonics of the root system of the bushes. Loosening depth 9–45 cm. The original design of the working bodies of the chisel with an additional degree of freedom provides a reduction in traction resistance by 12–14% and specific energy consumption by 1.2 and more times. Chisel complies with agrotechnical requirements in terms of fulfilling the quality indicators of the technological process. The number of frac-tions up to 50 mm 57.5–76.5 %, lumps over 100 mm 8–9 %. Universal design multiopera-tional garden and vineyard chisel allow its use in technologies of cultivation not only fruit, but also grain and row crops.
