Most farmers eventually have to deal with rocks in their fields or yards. Whether it’s a bunch of small ones that complicate planting gardens or crops or giant boulders that jut out of the ground and threaten to break any machine that inadvertently crosses their path, rocks of all shapes and sizes can be troublesome.
Indian agriculture is traditionally rainfed and dryland cultivation. Farming practices are heavily dependent on physical labor and the rising cost of cultivation, acute labor shortage to carry out the farming practices in time, lead many to think of alternative practices for improving their farm productivity in a sustainable manner. About 65 percent of the total cropped area in India is rainfed. About 45 percent of food grains and 75 – 80 percent of pulses and oilseed production come from rainfed areas.
How to Remove Small Stones from Farm
Talking about the tractor, he added that the stone remover requires 35 HP and above power. It consists of conveyor chains drive gearbox, PTO shaft and the bottom of the stone remover is connected with tines. Tippers are connected to the backside of the equipment.
While operating, the conveyor chain gets rotated at the rate of 12 – 16 rotations per minute. At the same time, the diggers loosen the soils exposing the stones which are pulled into the conveyor chain and collected into a tipper.
In dry regions, the soil contains a number of small pebbles and stones hindering farming activities such as land preparation and intercultural operations. Though rainfed drylands receive less amount of rainfall, the intensity during the short downpour is very high which leads to topsoil runoff resulting in soil erosion and more number of pebbles and stones getting exposed in the field. Over years, productive lands turn barren and uncultivable because of low fertility, reduced water holding capacity and the presence of these stones.
By using this machinery a farmer can harvest 2.5 acres of field in a day and preliminary cleaning was also made in this machinery at the time of harvesting, it was estimated that 40 percent to 50 percent of labor time can be saved. This machinery serves the multiple usages to the farming like stone removing, harvesting and preliminary cleaning of tubers and rhizomes, the innovator added. He said that the machine is capable of picking both small and big stones, but not boulders, from a depth of 15cm to 25cm in the soil. In a day it can be used to clear five acres.
