Abstract

In direct cut combining of crops, two factors are involved: grain losses and harvesting velocity which are significant in field harvesting. Omitting the cuterbar of COMBINE’s head and designing of a new head for separation of CANOLA’s pod from it’s stem needs basic information and data about the amount of force for stability of CANOLA plant’s roots in the soil. During past years, there has not been much work done on mechanical properties of this plant. Past year, in harvesting time, when the moisture of seeds were 9% and moisture content of plants 56/6%,the diameter of stem was measured in 3 replications. Three level of diameter size were determined which named: thin, medium and thick stem (11.3, 21.6, 25.6 mm). Required CANOLA UPROOTING force was obtained by using UPROOTING machine. Data were processed by japanies analyzer (TC-31K), then UPROOTING curves (force-time) were drawn. UPROOTING machine operated with, 0.01 m/sec., constant velocity. Results showed the required forces that were between 15/6 to 46/7 Kgf. In other word, in design of harvesting machine, the maximum requiring force for pod separation from it,s stem, should not be more than 15.6 kgf. In the research, the maximum power for a single CANOLA plant UPROOTING was calculated between 1.53 to 5.3 watt (jole/sec.). The results showed that CANOLA,s UPROOTING forces increases with increasing the stem diameter and decreases with increasing the UPROOTING time. For future needs ,an experiment were carried out on determination of UPROOTING force for flowering and seeding stage ,having respectively 81% and 75% moisture on wet basies. The UPROOTING forces for these two stages were more than those which required for harvesting stage. In the flowering and seed setting stages, under applied forces, crushing in stems happened, but in harvesting no stem was crushed and increasing the force, result fracturing.
