嫩薑深溝築畦機之研製
Development and Testing of the Chain Trencher for Soft Ginger
摘要
本研究設計並試製二台單行式嫩薑深溝築畦機，可提供給農民做為挖掘薑壟之用。雛型機以中耕管理機為行走部，分別配置8.5及10 Hp汽油引擎，原耕耘部位置則改裝成鏈式挖掘機構。其中第一型機以新開發之同心軸式雙速行星齒輪減速機降低田間作業速度至0.29 km/hr，同時於傳動系中設計一組過負荷保護傳動齒輪箱，可確保傳動軸組不致損壞。機體於道路操作時，只需切換行星齒輪組後，便可配合操作人步伐之4.91 km/hr快速度移動；第二型機則簡化第一型機繁複的機構設計，其加大馬力並以較快的速度0.52 km/hr於田間作業，而引擎反向組裝及挖掘鏈藉彈簧壓縮緩衝等，亦可達到動力傳遞與過負荷保護的目的。經測試原地靜態最大挖掘深度分別可達44及50 cm，行進間挖掘則為32及29 cm，而長10 m之薑壟作業時間僅約2.27和1.28 min，可較人工快達8與13倍。

The purpose of this research is to develop two prototype chain trenchers for soft ginger growers to excavate ginger ditches by 10 m length, 40 cm depth and 15 cm width. The first type machine is mounted on an 8.5 Hp cultivator. The orginal cultivating mechanism was taken off and replaced by a chain-type trencher, also uses a new developed double speed co-axial planetary reducer to slow down the field speed to 0.29 km/hr. Another over -load protection gear box is added in power line for prevention from damage. When moving on road, the machine can be drived at 4.91 km/hr speed by shifting the planet gear set to normal speed. The second type machine use same frame with a bigger 10 Hp engine has the working speed of 0.52 km/hr. The 10 Hp engine is mounted inversively to simplify transmission mechanism. Experimental results show that the maximum ditch depth (not in moving) done by the first and second machine reach 44 cm and 50 cm in depth, and about 32 cm & 29 cm maximum when in moving and trenching, and the working capacity of the trencher is about 2.27 minutes and 1.28 minutes as they dig a standard ditch. Preliminary estimation show that the working efficiency of the first and second type machine is about 8 times and 13 times of labor.
