一种林下滴灌施肥集成装置

Abstract

本实用新型涉及滴灌施肥技术领域，具体地说，涉及一种林下滴灌施肥集成装置，包括搅拌筒，搅拌筒内安装有肥料筒，搅拌组件包括搅拌轴，搅拌轴外侧壁固定安装有若干搅拌叶，肥料筒侧壁开有若干进水孔，搅拌筒一侧壁连通有压力泵，压力泵一侧设有升降盒，升降盒一侧连接有排肥总管，压力泵和排肥总管连通，排肥总管一侧壁连通有若干波纹管，波纹管上安装有若干滴灌头，波纹管的管端处固定连接有支撑组件。本实用新型在搅拌轴转动时，通过第一伞齿轮、惰轮带动第二伞齿轮旋转，进而使肥料筒和搅拌叶同步反向转动，使得肥料筒内的肥料在自身旋转和搅拌叶的双重作用下，与通过进水孔进入的水充分混合，解决了单一搅拌可能导致的肥料溶解不均问题。
