果园多功能机 ——深施肥装置的设计 摘要：针对一机多用既可以用于给果园施肥、覆土，又可以代替挖穴机，既适用于果树等大型植物，又适用于大型农田作物。果园多功能机包括：挖穴装置、施肥装置、覆土装置。挖穴装置分为三种形式，即螺旋式、铣刀圆盘式和履带旋转开沟式。施肥装置分为液体注入式和挖掘施肥式两类。挖穴装置首先要确定挖穴的方式，通过比较选择螺旋式，再通过设计计算来确定螺旋钻头的转速和结构。施肥装置采用挖掘施肥式，在深施肥过程中采用外槽轮式排肥器将肥料排放到漏斗内，最后将挡板来开将肥料排入施肥穴。覆土装置是在机架后面悬挂一对倾斜的覆土板，通过机械的前移来将覆土板前面的土壤刮进施肥穴内。从而确定总体方案。然后对改变动力传输方向的锥齿轮进行计算说明校核，最后对两个齿轮轴和轴承进行校核说明。 关键词：挖穴装置；施肥装置；覆土装置 Orchard muti-function machine apply fertilizer deeply the design of installation Abstract:According to a machine, is multi-purpose to be able to be used in applying fertilizer and covering earth to orchard , and can replace to dig cave machine, apply to the macrophyteses such as fruit tree , and apply to large scale farmland crop. Orchard muti_function machine includes: Dig cave installation , apply fertilizer to install , cover earth installation. Dig cave installation to divide into 3 kinds of form, screw type, the disc type of milling cutter and caterpillar are revolving to open ditch type. Apply fertilizer to install divide into liquid spoon-fed with excavate to apply fertilizer type two kinds. Dig cave installation the way that will first determine to dig cave , through selecting screw type fairly, determine structure and the rotational speed of spiral bit again through designing calculation. Apply fertilizer to install adopting excavate to apply fertilizer type, in the deep course of applying fertilizer queue up fat ware with outside groove ship type will fertilizer emission go to funnel , open baffle finally will fertilizer emit into to apply fertilizer cave. Cover earth installation is in frame back hang a pair incline cover earth board, since passing through mechanical reach will cover the soil before earth board to scrape enter to apply fertilizer cave. So, determine overall scheme. Then for changing power transmission, the bevel gear of direction calculates explanation school nucleus , checks nuclear explanation finally for two gear axle and bearing. Key words:Dig cave install
