Problems solved by technology
These methods have high detection accuracy and are suitable for laboratory detection, but they take a long time and cannot be directly applied on site
At present, when purchasing grain in China, there are still hand-touching and teeth-biting, and the moisture content of the grain is judged by experience, and the measurement results are extremely unreliable

Abstract
A grain moisture content detection device based on a grain picker belongs to the technical field of grain moisture content detection, and in particular relates to the grain moisture content detection device based on the grain picker. The invention provides the grain moisture content detection device based on the grain picker, being capable of improving grain collecting efficiency. The grain moisture content detection device comprises the grain picker which comprises a rear end handle and a front inserting body; the front end of the inserting body is a tapered pointed end, the rear of the inserting body is a semi-closed space in the shape of a circular groove; the inner wall of the semi-closed space of the inserting body is provided with a strip-shape capacitive sensor along the length direction of the inserting body; the output port of the capacitive sensor is connected with the input port of a capacitive detection circuit outside the grain picker, the output port of the capacitive detection circuit is connected with the input port of an A / D conversion circuit, the output port of the A / D conversion circuit is connected with the signal input port of a single chip computer, the display signal output port of the single chip computer is connected with the display signal input port of an LED (light-emitting diode) display part, and the keying signal input port of the single chip computer is connected with a key.
Description
Technical field [0001] The invention belongs to the technical field of grain moisture detection, and particularly relates to a grain moisture detection device based on a skewer. Background technique [0002] When buying grain, the moisture content of the grain needs to be tested. Excessive water content in grain wastes transportation capacity and storage capacity, which promotes the vigorous activities of grain life, which can easily cause heat, mildew, insects and other changes in grain. Due to the imperfect moisture detection technology in my country, my country is a large grain country with hundreds of One hundred million kilograms of grain was moldy and deteriorated during transportation and storage due to high moisture content, causing huge losses. Grain moisture is an important quality indicator, and the moisture content of grain needs to be tested during the transportation, storage and processing of grain. Therefore, grain moisture detection is of great significance. [00...
