          摘要:

          針對目前山地林果茶園挖穴作業人工勞動強度大和作業效率低的問題,本研究設計了一種具有行駛動力的山地林果茶園電動自走式挖穴機。該挖穴機能自動完成鉆頭進給行程與復位行程。田間試驗結果表明,該挖穴機單次作業平均挖穴時間為50.7 s,單次有效挖穴作業能耗為6.38 Wh,平均施肥穴深度為392.5 mm,平均施肥穴直徑為303 mm,行走速度為1.237 m/s,能夠順利通過15°斜坡。挖穴作業過程中鉆頭的進給與回程運動,均無需人工操作,可提高工作效率,降低勞動強度,并保證挖穴操作中的安全性。

          Abstract:

          In view of the large labor intensity of the excavation machinery in the existing mountain tea orchard, an electric self-propelled digger with driving power and automatic feed stroke and reset stroke was designed. In this paper, the digger is divided into five parts: the burrowing mechanism, the automatic lifting mechanism, the travelling mechanism, the supporting mechanism and the control system, meanwhile, the design and selection of the key components and the prototype manufacturing and assembly was completed. According to the field test results, the average burrowing time for a single operation of the digger was 50.7 s, the energy consumption for a single effective burrowing operation was 6.38 Wh, the average depth of the hole was 392.5 mm, the average hole diameter is 303 mm, and the orchard road speed was 1.237 m/s, the mud road speed was 1.202 m/s, and it can smoothly passed the 15° slope. In the burrowing operation, the feed and return movements do not require manual operation, which can reduce the labor intensity.
