1WX-90型植樹挖穴機設計
摘 要：現代新型挖坑機的研發(fā)主要向系列化、多功能和高性能方向發(fā)展。本植樹挖坑機是針對目前使用廣泛的江蘇50型四輪拖拉機配套而設計的。懸掛式挖坑機采用與拖拉機三點懸掛式聯接，即鉆頭在懸掛支臂的一端，支臂的另一端置于拖拉機懸掛支點上。
本挖坑機主要是對傳統(tǒng)的懸掛式植樹挖坑機的傳動部分和挖掘部分的改進。在主軸箱設計方面，根據江蘇50型拖拉機的傳動參數，合理的設計錐齒輪的傳動比以及強度計算等。在總體設計方面，盡量簡化挖坑機的結構，減少其零件數目，以降低成本。對于雙螺旋葉片設計，其直徑由下往上逐漸減小，其螺旋夾角也由下往上逐漸減小，以避免鉆頭工作時與塘壁發(fā)生碰撞和摩擦等情況，提高了工作穩(wěn)定性。
關鍵詞：挖坑機；懸掛；雙螺旋葉片
1WK-90-Type Planting Excavation Machine
Abstract: The digging machine of modern research and development of new main to the serialization, multi-functional and high-performance direction. The tree digging machine is currently used for a wide range of Jiangsu 50-wheel tractor designed package. Suspended digging machine with a tractor connected to a suspended three-point, that is, the bit at the end of suspension arm, the other end of the arm at the fulcrum of the flying tractor.
The digging machine is suspended from the traditional tree digging machine parts and the transmission part of the improvement of mining. In designing the spindle box, according to Jiangsu 50 tractor transmission parameters, and it needs a reasonable design of the bevel gear transmission ratio and the strength calculation. In the overall design, the digging machine tries to simplify the structure, reducing the number of its parts in order to reduce costs. Blade design for the double helix, whose diameter gradually decreases from bottom to top, the spiral angle also decreases from bottom to top in order to avoid the bit of work with the Tong-wall collisions and friction, etc., increased job stability.
Key words: Digging machine; Suspension; Double helix leaves
