In agriculture, threshing is one of the most important processes that farmers need to carry out after harvesting their crops, especially for grains like wheat, rice, corn, etc. Threshing is the process of separating the grain or seed from the plant structure or husk. It is usually done manually, but with the advancement in technology, farmers can now se machines to thresh their crops. One of these machines is a multi crop thresher.

A multi crop thresher is a powerful machine that threshes different types of crops such as wheat, rice, sorghum, maize, millet, sunflower, and other grains. It is an essential tool for farmers who want to save time and energy when threshing their crops. In this article, we’ll discuss the technical information of corn thresher machine, how to operate corn thresher, how to get good quality of machine, how to choose the most suitable machine, and the guarantee of your thresher machine.

Description of a Multi crop Thresher:

A multi crop thresher is a machine designed for threshing different types of crops. It is made up of several components such as a feeding hopper, a threshing drum, a blower, a sieve, and a discharge chute. The feeding hopper is located at the top of the machine and is used for the loading of crops to be threshed. The threshing drum rotates at high speed and is equipped with a series of threshing spikes that rub against the crops and separate the seed or grain from the husk. The blower is used to separate the seed from the chaff by blowing air through the mixture. The sieve is used to separate the smaller grains and debris from the clean seeds, and the discharge chute is used for the output of the threshed crop.

What Grain It Can Use:

A multi crop thresher is a versatile machine that can be used to thresh different types of crops. The grains that can be threshed using the machine include:

1. Corn

2. Mung bean

3. Sorghum

4. Maize

5. Millet

6. soybean and so on

Working Principle of Multi crop Thresher:

The working principle of a multi crop thresher is based on the principle of impact and rubbing to separate the seed from the husk. The machine consists of a threshing drum that rotates at high speed. The drum is equipped with a series of horizontally arranged spikes that rub against the grains as they pass through the drum. As the spikes hit the grains at high speed, the husk or chaff is separated from the grain. The grains then fall through a sieve with small holes, which separates the smaller debris from the clean seeds. The blower in the machine is used to separate the seed from the majority of chaff and debris by blowing air through the mixture while discharging the clean seeds through the discharge chute.

3. Turn on the machine and adjust the threshing drum speed according to the size and variety of corn being threshed.

4. Load the corn cobs through the feeding hopper, ensuring that they are well-dried and free from any foreign material.

5. The clean seeds would exit through the discharge chute, while the trash and small debris would go through the blower and exit through the waste chute.

6. After threshing, clean the machine thoroughly to remove any dust or debris that may have accumulated during the process.
