Reed Harvesting Koeping.

摘要

This project has in view to test if common farming machines can be used for reed harvesting on ice and how efficient they are. Our method was to harvest reed on ice and transport it to a terminal on land. The water depth in the reed belt is 0-2 meter. 0.4 - 0.45 m is demand for the harvesting machinery. The safety margin is then 100 per cent. Some different farming machines were tested, which gave the results as follows. A common moving machine is unsuitable because it lays down the reed in a compact, hardcatched swath. The trials with conventional chop harvesters showed that they functioned badly in reed. A precision-chop harvester, which picked up the swath of reed from the ice worked very well. Two small balers, a medium press and a hard press, worked well in the trials when they were droven carefully in swath-laid reed. Three different types of balers of big balers were tested. Of the two roundbalers the one with fix-chamber worked very well. In the fix-chamber press we used, the bale was formed by the sheet metal drums which surround the bale-room. The harvest capacity in reed was very high. This is true also for the third press which produced square, easily transportable bales. but the density of these bales was only half of that of the round-bales. An older precision chop harvester with fingerbar and swath board worked very well in the reed because of its rough construct. (ERA citation 08:033335)
