The purpose of our researches was to increase the efficiency and quality of the soil tillage in the intense orchard round – of stem and inter stem belts and to decrease the process energy intensity by means of the improvement of the technology and technological means of carrying out this operation.
The authors analyzed the existing technologies and technical means of the soil management in the orchard – of – stem and inter stem belts, presented the main drawback of the existing rotary cultivators with the vertical rotation axis that makes it impossible to manage inter stem belts in sensed intense orchards and chosen the investigations direction. The major above mentioned rotary cultivator parameters were substantiated for the soil management in the above named orchard belts. The program of the laboratory and field explorations was developed as well as the methods of conducting them and design documentation. The novelty and design peculiarity of the rotary cultivator construction were substantiated as well as the designation and principle of the action of its working tools. The cultivator experimental sample was made. The requirements to carrying out its testing were elaborated, the principal duality indicators determined as well as of its work efficiency. The cultivator laboratory and field testing was conducted. Its design scheme was presented as well as the total air in the operation. The main technical and technological indices of the rotary cultivator work were established as a result of the timekeeping observations. The preliminary calculations showed that the labour productivity when the above mentioned belts tilling with the studied cultivator increased by 1,2-2 times as compared to the hand – operated cultivation. The rotary cultivator work reliability was evaluated.
After the extensive checking up under the productional conditions and corresponding additional works the cultivator may be recommended to be introduced into production.
Key words: rotary cultivator, round-of-stem and inter stem belt, working tool, inter-row space, soil, intense orchard.
