This article is for general broadcast of the ammonium bicarbonate and so easy to deliquescence, bond, volatile, decomposition of manure and fertilizer on the schedule for the improvement of the mechanical structure design. Some have been recorded by the experimental data and is designed to improve the vibration of fertilizer auger-type structure. This structure is mainly of fertilizer from the fertilizer box, fertilizer tank base, vibration plate, trackwheel, screw auger of fertilizer and manure volume control panels, the structure of the basic principle is subject to vibration plate fertilizer under the action of vibration, and in formed inside the fertilizer flow. Such a structure can not easily clogged fertilizer, overhead, and agglomeration. The structure of fertilizer for agricultural machinery in Chinas current situation of fertilizer, good for general promotion. Key Words：Fat volume control board； Jog Dial – cam； vibration plate,；fertilizer apparatus 目 录 TOC \o 1-3 \h \z \u 1 引言 1 2 种肥简介 1 2.1固态种肥的分类及施用方法 1 1.2 肥料特性 3 2 排肥器 4 2.1 排肥器性能要求 4 2.2 排肥器的种类及特点 4 2.2 排肥器的选择 9 2.3 振动式排肥器的设计要求 11 2.3.1 调量板 12
