Creating and testing the efficiency of a rubber leaf chopping machine

Abstract

          The objectives of this research are to 1) build and 2) test the efficiency of a rubber leaf chopping machine. The tools used in the research were 1) a rubber leaf chopper and                           2) a performance test table. The researcher has designed and built a rubber leaf-chopping machine. To have the ability to chop the rubber leaves into smaller sizes. Then put it to a performance test. and analyze the obtained data with basic statistics such as percentages and averages.

          The results of the research found that: 1) agricultural machinery with the size (width x length x height) of 400x1,003x700 millimeters. There are eight cutting blades. The rubber-leaf input channel is trapezoidal. Electric motor power set, single phase 220V/50Hz, motor power                        5 horsepower, speed 1,500 RPM, can adjust speed to 2 levels (488 RPM and 950 RPM), and has wheels, making it easy to move. 2) Efficiency of the rubber leaf chopping machine Tested the chopping of rubber leaves at the specified speed, 5 times, 1 kilogram each, as follows: (1) At a speed of 488 rpm, it was found that the average rubber leaf fineness was 9.45 millimeters, the average weight after chopping was 0.96 kilograms, the average loss rate was equal to 0.04 kilograms, the average chopping time was 1.38 minutes, and the efficiency of the machine was 0.92, or 92%. and (2) machine efficiency. At a rotational speed of 950 rpm, it was found that the average rubber leaf fineness was 8.38 millimeters, the average weight after chopping was 0.87 kilograms, the average loss rate was 0.13 kilograms, the average chopping time was 1.18 minutes, and the efficiency of the machine was 0.87, or 87%.
