"Chintakayala Rambabu - A serial innovator of machines and
Chintakayala Rambabu, 46, Agiripalli, Krishna district, Andhra Pradesh moved to G Konduru, a Mandal headquarters in the same district, 20 years ago.
Rambabu had to discontinue his education after 10th standard due to his family’s precarious financial condition. . He began working as a day labourer to support his parents. After learning of Rambabu’s sincerity, Dharma Rao offered to take him to Aurangabad to explore further. Rambabu began with practiving on a lathe machine. He improved his skills and excelled in working with every machine available in the workshop of the employer in a very short period of time. Soon, he left his employer to care for his parents and returned to his village.He wanted start a small business using the skills he learned in Aurangabad.
After returning, Rambabu joined the“Ganapathi Tractor Works” after noticing that repairing and maintaining tractors and related machinery was a major need in the village. Rambabu moved to G Konduru with his family after working in that workshop for two years. He also learned to understand the needs of the customers.
However, Rambabu wanted to establish his own shop. With the knowledge he gained from his previous work and the deeper insights he gained about customer needs, he started his own workshop with a simple principle: “I listen to my customers keenly, understand their actual requirement and then make the product better in terms of meeting thoseneeds …” As this approach became the foundation of his business, his credibility grew, and people began to trust him more and more. His business expanded. As a villager himself, he was able to easily empathise with the other villagers, internalise their needs, and devise solutions with Samavedana thatled to highly valued innovations. His reputation quickly spread through word of mouth and he acquired a large number of new customers.
An ordinary person, without a higher degree but with faith in his ability, could create many useful products that are less expensive, require less effort, and produce better results.
Here are a few of Rambabu’s innovations:
Modifications to tractor with drill plough
Most tractors typically have a drill plough attachment for harrowing. Farmers use it to plough their land at shallow depth to place seeds and fertilise at right depth in the soil Because it is costly for farmers to drop each fertiliser separately in the farm, they mix 3-4 fertilisers together ahead of time and then apply it to the soil with a tractor drawn rill plough. Farmers have recently faced difficulties in mixing fertilisers due to labour shortage. Rambabu created a box with a few blades mounted on an axle that can be rotated by a handle The box was positioned atop the drill plough. Farmers can mix three to four different types of fertiliser in the box by rotating the handle. He added another feature to the machine that precisely places fertilisers in the soil as determined by the farmer. This reduced the farmer’s effort and ensured that only the right amount of fertiliser required was applied to the soil. Farmers were pleased with this machine; however, consistency and performance could not have been achieved despite spending 70-80 thousand rupees.
He attached e the drill plough 26 inches high from the ground level to use this attachment for crops up to two feet tall, particularly chilli and cotton. This allowed the plough to move freely without hurting crop. Because the fertiliser is dropped with the plough, it is not exposed to sunlight or moisture, ensuring that the maximum amount of fertiliser reaches the plants. He added an extra arrangement to the back of the tilling machine that forces the fertiliser deep into the soil before covering it with soil. He also made another arrangement for the machine to be used as a weeder in between the rows.
He is currently attaching a chain to the fertiliser box mixer by connecting it to the tractor’s tyres, which will allow the fertilisers to mix automatically when the tractor starts moving without the need for workers. This lowers the farmers’ labour costs.
Stone coal crushing machine
To protect the environment, restrictions have been imposed on brick manufacturing units that do not use commonly available coal. Rambabu devised an alternative by burning bricks with large-sized stone coal.
This stone coal is typically supplied in large blocks and sizes. Coal pieces measuring 25 and 40 millimetres are required for brick kilns.
Previously, brick makers would hire 10-20 workers to cut stone coals into 25 and 40 mm pieces for each brick kiln. This was both expensive and time-consuming. Their problems were exacerbated by a labour shortage. Brick manufacturers also showed Rambabu the existing machine, which only produces one size at a time, significantly slowing the process. He decided to build a single machine that could produce two sizes at the same time.
For power, Rambabu’s machine is connected to a tractor. When large coal blocks are fed into this machine, two sizes of coal pieces are produced: 25mm and 40mm, which can be directly used to burn the bricks. This machine takes three hours to burn one brick, compared to one month in the previous method of manually sizing coal. Rambabu’s invention has been a boon to brickmakers.
Rambabu has supplied 300 machines to brick makers in both Telugu states since 2014. These machines cost Rs. 85,000 each. Even now, his order book is full. This machine requires little maintenance, such as applying grease to the bearings and replacing blades and bearings as needed
Tractor wheels for mixing mud to mould bricks
Mud for bricks is prepared by soaking the greasy mud for a few days and then moving a tractor over it to make it soft and gummy. This method of using iron wheels on a tractor caused the tractor to overheat. Brickmakers approached Rambabu to solve this problem. He devised the idea of producing larger diameter Iron wheels, increasing the diameter from 48 to 60 inches.
The advantage of this approach is that it reduces the load on the tractor and allows it to move freely and easily, avoiding tractor overheating. According to Rambabu, this strategy improved the tractor’s mileage.
