agricultural engineering. SUBSTANCE: greenhouse agrobridge has girder 1, self-propelled carts 2, wheels with tenons 3, girder lifting motor-reducer 4, replaceable platforms 5 carrying working tools, cabin 6, transportation cart 7, drums attached to replaceable platforms 5 and positioned for rotation around longitudinal shafts 9, and electric retainers 12 for fixing drums in required positions. Working tools are mounted on drums. Such construction allows only needed working tools among tools fixed on rotary drums to be lowered onto ground. Agrobridge may be used for performing agricultural works in greenhouse, as well as on farm land adjoining to greenhouse. In latter case, wheels with tenons are replaced with wide rubber-and-metal caterpillars. EFFECT: wider operational capabilities and increased efficiency. 2 cl, 9 dwg |
