摘要
针对现有果园机械化水平较低、缺少集成式设备问题,依据果园农艺要求设计了一种多功能果园田间管理机。该机器为自走履带式有级变速,装配有大块有机肥宽深开沟器、粉状与粒状无机肥开沟施肥回填一体装置等,以完成果园的开沟和施肥等多环节的机械作业。通过快换装置实现开沟和施肥等功能的简便拆卸更换,以保障多功能管理机作业的可操作性和可靠性。经过田间试验,测知管理机能够完成35cm宽、0~40cm深的开沟,施肥深度可达到35cm,作业速度为350~2 000m/h,机身高度90cm,长度270cm。由于机型矮小,转弯半径最小1.8m,行走灵活,因此既可用于现代宽行矮砧密植果园,又可用于传统乔化果园。
In view of the low level of mechanization in orchards and the lack of integrated equipment,a multi-functional orchard field management machine was designed according to the agronomic requirements of the orchard.The machine is self-propelled with crawler and has a finite-step gearbox.In order to complete the series of mechanical operations of orchard trenching and fertilization,two core parts were designed.One is a wide-deep opener for large organic fertilizer,and the other one is a 3-in-1 device(ditching,fertilizing and backfilling)for powder and granular inorganic fertilizer.The opener and fertilizing equipment can be easily disassembled and replaced by fast-change device.In this way the operability and reliability of the machine can be ensured.Based on the field trials,the machine is capable of ditching as wide as 35 cm and as deep as 40 cm.The fertilization depth can reach 35 cm with 350-2000 m/h working speed.Due to the short-tiny shape(90 cm in height,270 cm in width),the machine has much flexibility with a minimum radius of 1.8 meters.Thus,a new multi-functional integrated device is designed for orchard mechanical operations which can be used in modern wide-row dwarf anvil orchards,as well as traditional Qiaohua orchards.
