SUMMARY OF THE INVENTION
The Multipurpose Sieving Machine is designed to provide an efficient and automated solution for material separation, addressing the needs of both agricultural and industrial applications. The invention is built with a sturdy frame of mild steel (MS) rods and features a sieve that moves in a to- and-fro motion. This motion is generated by an AC motor attached to a pulley and belt system, which ensures smooth and controlled movement for effective material sorting.
The primary purpose of the invention is to streamline the sieving process for various types of materials such as grains, seeds, sand, and other granular substances. Its multipurpose nature allows it to be used in different fields, making it versatile enough to handle multiple tasks by simply changing the sieve or adjusting the motion as needed. The machine is engineered for low maintenance and energy efficiency, ensuring reliable performance even in environments with limited power resources.


The Multipurpose Sieving Machine is designed for efficient material separation in agriculture and industrial applications. It automates the sieving process for granular materials such as grains, seeds, and sand, providing a cost-effective solution for sorting and cleaning.
AC Motor The machine is powered by a 230V single-phase AC motor with a frequency of 50 Hz, delivering 180 watts of power at 1440 RPM. This motor drives the system, converting electrical energy into mechanical motion with a current rating of 2.5 amps.
Pulley and Belt System A pulley-belt mechanism translates the motor's rotational motion into a to-and-fro motion for the sieve. The system includes two pulleys: a small pulley (15 cm) and a large pulley (25 cm), both made of mild steel. The V-type belt (model: V-40), made of rubber, connects these pulleys, facilitating smooth and efficient power transmission.
Sieve Machine Frame The frame is constructed from mild steel rods, measuring 100 cm in length, 40 cm in width, and 30 cm in height. The rods provide stability and durability, supporting the entire assembly and ensuring smooth operation.
Sieve The sieve itself is a mild steel mesh, measuring 30 cm x 30 cm. It efficiently separates materials based on size, allowing smaller particles to fall through while larger ones remain on the surface. The mesh size can be easily adjusted to accommodate different materials.
Connecting Rod A connecting rod made from mild steel measures 21 cm in length and approximately 1 cm in diameter. It transmits motion from the motor to the sieve, ensuring a smooth oscillation during operation.
Functionality The machine operates by utilizing the AC motor to drive the pulley system, which moves the sieve in a to-and-fro motion. This agitation facilitates effective material sorting. The robust mild steel
