Description

TECHNICAL AREA

The present utility model relates to the technical field of agricultural measuring instruments, in particular to a device for measuring a hardness of a corn cob.

STATE OF THE ART

Corn cob rot is a corn disease closely related to human health. Corn cob rot occurs in corn producing areas around the world. The fungal complex of this disease can produce several mycotoxins, such as Aspergillus flavusa and fumonisins, etc., which are harmful to human and animal health. Ears of corn as well as kernels of corn can be affected by corn cob rot. The upper part or middle part of the infected ears of corn changes color, with pink, blue-green, black-gray, dark-brown or yellow-brown mold layers, i.e., thallus, conidiophores and the conidia of the pathogenic castor oil being formed. The infected grains are dull, not full, brittle, and are empty inside, which is often filled with intertwined hyphae. The cover leaves of the diseased part of the ears of corn are often penetrated by dense hyphae, stick together, adhere to the ears of corn and therefore cannot be easily peeled off. If the maize stored in the warehouse is infested, hyphae and conidia of various densities and colors wash inside and outside of the grain pile, the grain pile smelling of mold. A prolonged stay of the matured and non-harvested maize in the field increases the likelihood of core rot. Heavy rain in late autumn can make corn kernels sick. If the corn kernels are not dried and their moisture content is high when stored in the warehouse, the warehouse is not compacted during the storage period and the temperature in the warehouse rises, the saprophytic spread of various molds is also favored, whereby the corn kernels rot or mold.

According to research, the incidence rate of corn cob rot is related to the hardness of the corn cob. The higher the hardness of the corn cob, the less likely it is that the corn cob will become infected with cob rot. Therefore, a device has to be developed by which the hardness of the corn cob can be measured.

In order to achieve the above object, the present utility model proposes a device for measuring a hardness of a corn cob.
