Abstract
1．此種小型聯台收穫機，體積小，重量輕，移動方便，但工作能量低，故適台於小農經營或不良地形區域，不適宜代割或大面積栽培應用。
2．由於體積小，脫穀能量受到限制，對於各種作業條件的適應性較乏，日工作量的差異性頗大，由0.4到0.6公頃。
3．配合收穫機使用，水稻移植作業生以使用動力插秧機或改成寬行密植為優。
4．配合收穫機收穫，水稻品種需要發展者應為不易倒伏性，或不染患枯葉者；其次為發展脫粒性適宜之品種。又如在來種若能育成葉尖低，穗部高，使穗部和葉部分離則更佳。
5．輕露水的收割尚勉可應用，但重露或雨水淋濕時，此型下置式脫榖機即失去效用，因此雨季來臨時，影響作業甚大。
6．此小型收穫機，可以達到節省勞力及改善作業方式的目的，工作量約為人工的3~4.5倍。
7．作業成本尚難達到低於日前的手工作集，此應再改良，使作業量增加，機構簡化，耐久性加強和年工作量適當增加。
8．作業成本中，以修護費用及折舊費用所佔比率最大，分別為30.8%及24.6%。
9．機動性的加強，及附著高水份稻株的適懸性懸再加強。
1. This small sized and light weight portable rice combine, which can be moved to any place very easily although it is lower in efficiency, is suitable for small farm or for places where big rice combine couldn’t be used. Hence, it is understood that this rice combine isn’t suitable for hire or adopted by extensive farm.
2. Since the capacity of this portable rice combine is comparatively very small, hence, not only the threshing capacity of this combine is affected very much, but also it will be very poor to meet various kind of work conditions in the rice field. Furthermore, an unstable daily working capacity or output will be the immediate result. The ordinary working capacity of this combine is ranged from 0.4 to 0.6 ha. per day.
3. In the case of matching the future developing and exploitation of this combine, it is necessary that the rice seedlings should be transplanted by power rice transplanters or a kind of new row-spacing transplanting system should be adopted, that is to say, the row distance should be increased and the spacing should be decreased compared with the traditional row-spacing transplanting system.
4. If this rice combine will be adopted in Taiwan in the near future, it is quite obvious that new kinds of rice varieties which are resistant to lodging or resistant to straw disease and have better shattering effect should be bred. Furthermore, the new bred variety of the native variety should have short leaves and higher rice head. It will he the best new bred native variety if the rice heads are much higher than the leaves in the same rice plant.
5. This rice combine can be operated in the rice field in the light morning dew. However when this machine is operated in a heavy morning fog, since the rice plant has been covered with dew drops or water drops at that time, the downward feeding type rice thresher in the rice combine will go out of work completely in a very short period. Hence, it is a matter of fact that the efficiency of this machine will be affected very much during the rainy season.
6. The merits of this portable rice combine are indicated in this paragraph. This machine can be operated with less labor. In the meantime, this machine can he also proceeded in a much improved way. The working capacity of this machine is about 3 to 4.5 times than the traditional way.
7. The total operation cost of this machine is still higher than by adopting the traditional method. Hence, a modification of the structure of this combine in the purpose of increasing output with a much simplified new structure and a longer life is in urgent need.
8. The maintenance fees and depreciation of the machine are the lion share among the total operation cost. The actual proportion of the maintenance fees and depreciation are 30.8% and 24.6%of the total operation cost respectively.
9. The mobility as well as the threshing system should be further strengthened so to meet the necessity when the rice grains have contained heavy water moisture content or covered with water drops.
