Background
In the Bo Klua Thailand, rice farmers are challenged everyday to go through the routines needed to have a successful harvest. One of the fundamental aspects of farming is to keep your crop free of unwanted pests and weeds. Our group has been assigned the project in which we design a more ergonomic and effective method of removing weeds from Thai rice fields compared to the current weeding method. In this region of Thailand, the grade of the landscape is mountainous and hilly and the farmers utilize this landscape to plant their crops every year. However, one of the challenges when it comes to farming on such an incline, many farmers are plagued with chronic back pain from their current method of removing weeds. One of the goals for our weeder is to reduce the pain caused by the tools that the farmers are currently using. Another thing that we need to consider is that the farmers of this region are considered impoverished, meaning that the average person has to live on less than $2 per day, making the price of our device an important factor in our design. We will try and keep the cost of our device as low as possible while still performing well as a weeder to give the best advantage for Thai farmers to make the most profit from their crop harvest.
Tutorial
Needs: three one foot sections of 1/4 inch steel rods, a nice handle (we used a broom handle), and hose clamps.
1. Started by using a band saw to cut into the end of it so that the steel rods will have a
flat place to stay.
2. Reduce thickness from the extra piece that has been removed so that there is room for the rods.
3. Cut steel rods into 1' long pieces and bend them to specification.
4. Weld the rods together to form the claw end of the tool.
5. Sandwich the metal claw in between the two wooden pieces at the end of the tool and use hose clamps to keep it in place.
