Design and Fabrication of Weeding Machine -Mechanical Agricultural Project

ABSTRACT

In today’s world every thing is getting modernized. Agriculture fields are slowly destroying and these lands are used for some other purpose. This is because the income from agriculture is less although the work involved is high. Most of the field work is done manually and so the farmers depend on the field workers for doing it. Because of the higher pay offered in other sectors like construction, workers prefer those jobs and so agricultural sector takes shortfall of manpower. This being the scenario, workers are not available for the works such as plucking out the unwanted grass and weeds growing in between the plants. It is very important to pluck out the grass and weeds in order to obtain fruitful results from the cultivation, as the grasses and weeds observe a part of nutrition given to the plants.Given the present situation, removing weeds becomes a costlier affair. In order to address this problem, this project proposes a simple, economical and efficient machine to remove the weed, which would be operated by a single person – savings of labour as well as time. The machine has been designed, fabricated and tested.

介绍
随着农业面临的农业，需要自动化该领域的各种活动，或者成为当天的需求。考虑到这一点，设计了一台简单的机器，用于去除水稻植物行之间的杂草和不需要的植物。当机器移动时，杂草拆卸器去除植物之间存在的杂草。该机器可以有效地用于诸如稻田等农业领域。为了在农业领域中使用这款机器，种子应在等于或大于本机的宽度的距离处播种。本机在无需使用任何电机或发动机的情况下设计简单。仅使用链条和链轮布置。这台机器消除了许多工人的需求，使工作更轻松，经济高效。

SPECIFICATION OF THE MACHINE

• Height of the machine : 1m
• Width of the machine : 0.55m
• Breadth of the machine :0.75m
• Weight of the machine :50kg
• Width of the weed removed by the cutter (Cutter width) :0.4m
• Average speed of weed remover :150rpm
• Average travel speed of the machine :50rpm
• For one revolution of the handle, the depth of cut : 6mm

ADVANTAGES AND DISADVANTAGES

• Mechanism is a simple one.
• Motor or Engine is not required.
• One Labour is enough for operation.
• Working is very easy compared to primitive work method.
• Initial and maintenance cost are less.
• Time consumption is less for weeding.

缺点

• Rotation of weed cutter is slower, so weed removal rate is less.
• More skilled Labour is need
