This engineering project is to design and develop the car overturned the agricultural productivity on the kaleidoscope is controlled by remote. The rice harvested from the peel test car hook or rice is damp.And the performance of the model by the project design, the car. The rake teeth harrow screw with programs Solid Works โครงรถมี length 0.8 meters wide 0.5 meters, rake, both long 1 meters, harrow teeth, each tooth difference 12 cm, harrow สกรูมี outer radius 9.8 cm and the pitch 4 cm. The characteristics of the car is square with tricycle. The rear wheels are one wheel is a wheel, front wheel independent when forced to any one wheel running will be เลี้ยวโค้ง.3.6 m2 in testing the speed 0.66 M / s turning radius equal to 60 cm. The distance the remote can control farthest of 50 m. And the battery used for a long time around 5-6 hours
.After the test the reversal and spread of paddy. Find the working rate of the car overturned as 0.324 Rai / hour, the working rate of people who can 0.0139 Rai /ชม.It can be seen that in the area the test rate. Equipment in the same smooth rice (harrow teeth and harrow rotary) cars will work twice as people do. The specific power of 4.05 Rai / KW-Hr.And performance in reversal and spread of paddy of this car was 80%
