What is a corn thresher

The corn harvest season is almost here. In the past, corn was threshed manually, and the laborious process of harvesting was often characterized by low efficiency and high intensity. However, the advent of corn threshers has begun to change this situation. Corn threshers have become an indispensable piece of equipment in agricultural production.
I. Working Principle of a Corn Thresher
A corn thresher primarily separates corn kernels from cobs through mechanical action. Its core workflow includes: 1. Feeding System: Corn cobs are fed into the feed port via a conveyor belt or manually.
2. Threshing Mechanism: Utilizing a drum and grid design, the threshing teeth on the drum rotate at high speeds to strike the cobs.
3. Separation System: Corn kernels fall through the grid, and the cobs are removed.
4. Cleaning Mechanism: Some models are equipped with a fan to remove impurities and debris.
II. A corn thresher consists of three parts:
Frame: Provides overall support and stability. Made of high-quality welded steel, the frame is equipped with bottom anchors and shock-absorbing pads to reduce vibration and movement during operation, ensuring stable threshing. The transmission and drive section consists of an electric motor (for electric corn threshers), a speed reducer, a pulley, and a drive shaft. It provides stable power to the threshing unit. Adjusting the transmission ratio controls the threshing speed to accommodate varying moisture levels (for example, dry or semi-wet corn cobs). (This differs from manual corn threshers or maximizer corn threshers (manual hand-cranked threshers) that rely on manual power.)
The threshing section includes a threshing drum (with threshing teeth/threshing plates for separating kernels), a concave screen (with holes for kernel/cob separation), a feed hopper, a kernel outlet, a cob outlet, and an impurity outlet. The drum and concave screen form the threshing chamber, where the corn is threshed.
III. Advantages of Corn Threshers:
1. The productivity of a single thresher is equivalent to that of dozens of people.
2. The cost of machine threshing is much lower than manual labor.
3. The threshing efficiency can reach 99%, with a broken kernel rate of less than 2%. The emergence of corn thresher is one of the signs of agricultural modernization. While improving agricultural production efficiency, it can also reduce the labor burden of farmers.
