A buoyant constant pressure fertilizer applicator and its application method belong to the field of pesticide, liquid fertilizer and the technical field of adding medicine equipment in the water plant. Fertilization device is composed of a sealing tank, floating plate and fertilizer bag connected; the roof closed tank is provided with a material inlet and exhaust valves; the bottom sealed tank is provided with a water inlet pipe, a fertilizer discharging pipe and the drainage pipe, the inner wall of the sealed tank is provided with a plurality of semi-circular guide rod, symmetrical arrangement, the floating plate can slide. In a closed tank down through the guide rod can not rotate, the floating plate is arranged on the bottom surface of the cylindrical groove, fertilizer bag is arranged on the roof between the floating plate and closed tank, the upper fertilizer bag through the inlet seal flange and fixedly connected with the lower end of the fertilizer bag sealing cap is fixedly connected with the floating plate through the through hole thread. The invention has the advantages of novel structure, the working principle is clear, due to the buoyancy of liquid fertilizer is constant, continuous flow, so even fertilization, zero energy consumption, will not cause the pipe head loss, especially suitable for low pressure drip irrigation and fertilization system, has great practical and social and economic benefits.
【技术实现步骤摘要】
浮力式恒压施肥器及其应用方法
本专利技术属于农药、液态肥料和水厂管道加药设备
,涉及一种施肥(加药)装置及其应用方法,具体的说是涉及一种用于农业液态肥料喷滴灌系统的浮力式恒压施肥器及其应用方法。
技术介绍
随着国家对农业重视度的不断增加,农业设施得到了有效的推广,农田灌溉面积日益增加,肥料、农药等的消耗量也越来越可观。施肥装置是节水灌溉配套系统中不可或缺的基本组成部分,其性能的优劣直接影响到灌溉施肥的质量和农作物产量。传统液态肥料投加方法有两种,一是采取电动泵在总管上进行投加,另一种是利用喷滴灌系统自身水压差注入。电动泵投加有泵吸和泵注式两种方式,适合大型农业公司同一栽培品种模式,需要电力以及一套自动控制装置调节加肥比例,装置价格高,应用方式不灵活。差压式投加方式有真空吸入法、水力驱动活塞(隔膜)泵、自压注入法、压差加药4种形式。真空吸入法利用喉部流速增大产生的真空,将肥液均匀的吸入灌溉管道与水混合,存在的问题是对运行压力要求高,水头损失较大,倒吸现象严重,吸程有限。水力驱动加药(施肥)泵依靠灌溉管道自身水动力驱动活塞运动将药剂吸入后注入灌溉管道,由于无需电 ...
