Kinematic scheme of equipment to reed harvesting machine MRS

Abstract

The reed harvesting machine MRS has been designed in INMA Bucharest to correspond to environmental requirements specifically of the Danube Delta Biosphere Reservation (DDBR), regarding the harvesting of reed vegetation located on the margins of the canals and lakes, as well as the reed vegetation of the floating islands, in all ground conditions, but especially in deep water conditions. The reed vegetation is a great ecological danger for the DDBR, annual GHG emissions due to fire, in case it is not harvested at intervals of 1-2 years. MRS is the machine of a new technology that provides the reed vegetation harvesting as sheaves, throughout the year, but especially during the warm season, when the reed vegetation is still bearing leaves, the harvested material making it suitable to obtain alternative energy. To harvest this vegetation, the MRS equipment was designed to realize cutting, forming and binding the sheaves of reed vegetation in deep water conditions. For not to influence the MRS floatability, regardless of the load size, the equipment has been designed with a reduced weight, being equipped with its own float. The paper presents the kinematics scheme of the MRS equipment transmission and the correlation of its characteristics to achieve the functions, regardless of the speed of harvest. The equipment transmission is driven by a hydraulic motor with adjustable speed, being composed of a transmission with gears and levers for the cutting device and a transmission with a chain for drive the formation and binding mechanisms of the sheaves.
