Tips On How To Maintain and Operate a Threshing Machine Easily

Threshing is an agricultural operation for detaching the grains from the cobs, ear heads, and pods. This machine is widely used to separate grains from the harvested crop and offer clean grain without any loss and damage. Threshing, broken, un-threshed, blown, and spilt are examples of grain loss. But a thresher machine minimizes these problems easily. It is certified that total grain loss should not be more than 5 per cent and the broken grain should be less than 2 per cent.

During threshing, broken, un-threshed, blown, and spilt are examples of grain loss. But a thresher machine minimizes these problems efficiently. It is certified that total grain loss should not be more than 5 per cent and the broken grain should be less than 2 per cent.

How To Operate?

First, start the engine.

Then Load the feed tray with the harvested crop with the help of 3 to 4 persons. Ensure that the cleaning screen is free of clinging straw when threshing wet material. Try using a stick to remove the clinging straw from the oscillating screen to avoid accidents.

Place the harvested crops on the feed tray with the panicle away from the operator.

Adjust the feed rate for feeding the crop at a uniform rate and maintain a maximum feeding rate without overloading the engine.

Hold the crop bundles for a little time at the feed opening for partial threshing when the material is longer than 40-50 cm for higher threshing efficiency. Short, panicle-harvested materials may result in high unthreshed losses and longer-cut material will reduce machine output and clogging of the machine.

Adjust blower shutters to give more air for a cleaner output and the airflow needed for winnowing.

Adjust the angle of the wind board and the blower opening according to the threshing conditions. For dry paddy, it should be on maximum inclination and for threshing wet paddy, the inclination of the wind board must be reduced.

Use the stripper bars for reducing capacity and increasing the amount of finely chopped straw that passes through the concave when threshing overly mature crops.

Reduce the feeding rate when threshing wet or decomposed materials to avoid overloading. Open the cylinder cover regularly to remove straw and chaff collection at the lower concave.

How To Maintain?

Lubrication of cylinder and fan bearings with good-quality grease every 25 hours is essential. Also, apply a little amount of oil to all hinge points regularly.

Regularly, inspect the machine for worn out, loose, or damaged peg teeth, cylinder, open bars, discharge paddles, and other parts. Kindly tighten, repair, or replace the Missing bolts or nuts.

Reduce the belt tensions by loosening the idler pulley and mounting bolts of the engine.

Regularly, check the engine crankcase oil level at least every 4 operating hours and also follow the engine manufacturer’s manual for oil change intervals and oil grade.
