Hand-operated resistance type grain moisture meter

Abstract

The invention discloses a hand-operated resistance type grain moisture meter. The meter comprises an upper cover plate and a lower cover plate which are fixedly connected through screws, wherein a sampling mechanism is mounted between the upper cover plate and the lower cover plate and provided with a rotating mechanism inside; a through hole penetrating through upper and lower end surfaces of theupper cover plate is formed in the upper cover plate; a sample inlet is formed in one side of the upper cover plate; the sampling mechanism comprises a bottom plate, a silicone pad, a stress frame, aladle and a sleeve; the rotating mechanism comprises a sampling screw, a fixed station and a knob. The hand-operated resistance type grain moisture meter is reasonable in design, can rapidly measuremoisture in rice, wheat, corn and other grains and is small in size and convenient to carry; grains on the ladle are crushed by the sampling screw, the moisture content of the grains is calculated after the resistance value is acquired, operations including sampling, sample discharging and the like are very simple and convenient, the uniformity and the accuracy of measurement results are kept under the limiting action of a circular limiting blocking boss, the measurement efficiency is improved, and the grain moisture meter has good use and popularization value.

Description

technical field [0001] The invention belongs to the technical field of measuring instrument manufacturing, and in particular relates to a grain moisture measuring instrument, in particular to a hand-operated grain resistance moisture measuring instrument. Background technique [0002] Moisture content in grain is an important indicator for evaluating grain quality, and it is also the main reference basis for purchasers to grade and set prices. A difference in moisture is worth a penny per catty. The state divides grain quality into five grades. The bulk density of wheat and corn, and the roughness rate of rice are the main indicators. The first grade is the highest, the fifth grade is the lowest, and the grain below the fifth grade is the second grade. Other foreign-grade grains are priced by the purchasing enterprises according to the market conditions and purchased by themselves. The method of increasing the amount of grain moisture, impurities, etc. has been clearly stip...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a hand-operated grain resistance moisture meter, which can quickly measure the moisture content of rice, wheat, corn and other grains through a reasonable design, and is small in size and portable. Convenient, the sampling screw crushes the grain on the spoon, and calculates the moisture content in the grain after collecting the resistance value. Uniformity and accuracy, improve the efficiency of measurement, solve the problem of large measurement error and low efficiency of grain moisture
