Low-damage threshing method for corn ear

Abstract

A low-damage threshing method for a corn ear comprises the steps of establishing a corn ear circulation force balance model according to the corn ear needing to be threshed, wherein the method is that the resultant force of stresses of a corn ear kernel in the horizontal, longitudinal and radial directions is defined as the circulation force; establishing an ear kernel building formula, namely a horizontal building unit and a gap building rule and establishing the arraying method for the whole corn ear kernel by the rule; analyzing the stresses of the corn ear kernel in the horizontal, longitudinal and radial directions according to the established arraying method, and establishing the corn ear circulation force balance model; calculating the size of the minimum force capable of breaking the circulation force balance according to the model, utilizing a wedge-shaped impacting head to apply the calculated force to a gap A on the corn ear for impacting, and threshing the corn ear. According to the low-damage threshing method for the corn ear, the corn ear kernels can be fast separated from the corn ear in a low-damage and low-energy consumption mode; the method can be used for an industrialized low-damage corn ear threshing and manufacturing a new corn ear thresher and has broad application prospect.

Description

technical field [0001] The invention belongs to the theoretical research field of corn grain threshing, and in particular relates to a low-damage corn ear threshing method. Background technique [0002] Corn is one of the three major food crops in the world. Corn threshing is a key link in harvesting work. It determines the degree of damage to corn kernels. Damaged kernels are prone to mold, insects, and easy to break. They are not suitable for long-term storage and can reduce their market value. and export value. [0003] Corn threshing is different from other grain threshing. The corn kernels are bound to the corncob through the fruit stalk, and the combination of the grain and the fruit stalk is relatively strong. In addition, when other grains are threshing, there is no force mutual support between the grains, but on the corncob, the grains are closely arranged, and there is a strong mutual support between the grains, and the existence of the force between the grains ha...

AI Technical Summary

Problems solved by technology

In addition, when other grains are threshing, there is no force mutual support between the grains, but on the corncob, the grains are closely arranged, and there is a strong mutual support between the grains, and the existence of the force between the grains has a great impact on the corn threshing. Difficulty has a significant impact

The current corn cob kernel threshing method has damage to the kernel, and is laborious and consumes a lot of energy
