Accuracy, Power Consumption and Environmental Protection of Shuttle Gantry Module in Arable Farming
The theoretical and the experimental researches of guidance, energy consumption and environment protection of the shuttle gantry module are submitted. Influence of a micro-relief, chassis speed differences and correction intensity for accuracy of guidance has been determined. The characteristics of the chassis have more influences for accuracy of guidance than a rough ground. It is not effective to supply more than 60 % of oil flow for the chassis with a lower speed, because it has a negative influence on the accuracy of guidance and on the consumption of power. When distance between the optical sensors is 50 mm, the maximum declination of guidance from mean trajectory is 33 mm. The useful factors and perspectives for energy saving and environment protection are established. The energy demand for chassis and operating working parts do not match in time. 3.5 - 4.5 kW installed power is enough to operate the module. The resistance of the chassis moving through constant technological tracks and that of the implemented carriage moving though beam are low. The energy consumption that is of no avail to soil deformation decreases to minimum. The resistance power of implements passes to the gear. Soil in the plant vegetation zone is not influenced by chassis. Inter-row could be reduced. Thus, there emerges a possibility to satisfy energy demand by alternative energy sources, to reduce pollution, and the deleterious influence on soil features. Direct human participation in technological processes is not required. The dependence on meteorological conditions is reduced. In order to calculate energy consumption, the operation efficiency of implements and chassis was established. Common efficiency of the module is calculated as a reverse value of common working time input. 40 m length beam will allow working at 0.42 ha/h efficiency. Positioning energy is just 0.6 kWh/ha, common one – 8.6 kWh/ha.
