摘要

目前,孟加拉国农民在农田中使用手动喷雾器或机动喷雾器。一般在农业领域,传统的或传统的技术,如肩扛式喷洒系统,因为它更便宜,易于使用,成本更低。继续使用传统能源将面临价格上涨和能源枯竭的高风险。如今,人们非常需要“节约能源”和可再生能源的应用。本文介绍了一种太阳能喷涂系统的设计、研制和评价。本研究的具体目标是考虑所需的喷洒速率、轻重量、低成本、更快的覆盖面积和高现场效率等参数来设计和制造太阳能喷雾器。采用MS杆架和带水位指示器的四轮小车构成了一种双喷嘴喷雾器,该喷雾器的电源为直流电池(12伏,8.2 Ah),通过太阳能电池板供电,由直流电机(12伏,2A)驱动。整个装置是便携式的,由一个工人操作。该设计主要消除了肩部安装的喷雾器设置造成的背部疼痛,使用不可再生和危险的化石能源,大量使用人力。该机器与传统喷雾器进行了比较,发现效率更高。单喷嘴的泵效率为83.33%,双喷嘴的泵效率为93.33%,比手动喷雾机节省58%的时间。该机器的运行成本为802tkha -1。太阳能喷雾器的资金回收系数为0.26,资金消耗为1520塔卡,年成本为41665塔卡。

DESIGN DEVELOPMENT AND PERFORMANCE EVALUATION OF SOLAR POWERED SPRAYER WITH WATER LEVEL INDICATOR
Currently in Bangladesh farmers use hand operated sprayer or motorized sprayer in agricultural fields. Generally in the agricultural field, traditional or conventional techniques like shoulder mounted spraying system have been used because it is cheaper, easy to use and less costly. Continuous use of traditional energy resources will have high risk of rising in price and energy depletion. Now-a-days there is a great need for ‘’conservation of energy’’ and application of renewable energy. This paper presents the design, development and evaluation of a solar powered spraying system. The specific objectives of this research is to design and fabricate the solar powered sprayer by considering parameters like desired spraying rate, low weight, low cost, faster coverage of area and high field efficiency. A two-nozzle sprayer was fabricated with MS bar frame and 4-wheel trolley with water level indicator which runs on power source as a DC battery (12 volt, 8.2 Ah) via solar panel and runs by a DC motor (12 volt, 2A). The entire unit is portable and is operated by one labor. The design mainly eliminates the shoulder mounting sprayer setup which causes back pain, uses of fossil power which is non-renewable and hazardous and extensive use of manpower. The machine was compared to conventional sprayer and found more efficient. Pump efficiency almost 83.33% found for single nozzle and 93.33% for double nozzle and the sprayer is 58% time saving than manual sprayer. The operating cost of the machine was 802 Tk ha-1 . Also found capital recovery factor, capital consumption and annual cost of the solar operated sprayer were 0.26, Tk 1520 and Tk 41665, respectively.
