How to use Hengaode instrument upgraded version weight Instrument use: This product is widely used in bulk density measurement of crops such as wheat, rice, sorghum, corn and so on. It reflects the fullness of rice and corn kernels, and is affected by moisture and impurities. Corn bulk density is now used as the basis for grading, replacing the past pure grain rate. National standard requirements: Bulk density is one of the mandatory inspection items for grain purchase. This product is measured according to the LS / T3701-1993 "HA / HGT-1000 Grain Bulk Density" standard and the "reference standard" in the standard and the new national standard GB1353-2009 "corn" Developed based on grain density requirements. The product passed the standard requirements to measure the bulk density of grain and set its grade, so it played a key role in grain purchase, storage and processing Upgrade performance characteristics: 1. Taking into account the actual application situation and applicable to different work places, convenient for different users to carry and use, the country's first grain weighing device with "charging characteristics"; 2. The product uses imported high-density, high-reliability SMD components to replace the traditional electronic components, so that the internal structure saves space for component installation; 3. Adopt advanced electronic weighing technology and computer technology to realize the automatic printing of test results while displaying the weighing results; 4. The mechanical parts have been carefully selected and carefully processed, and the unique external color tone makes the appearance more novel and beautiful; 5. This product also has the characteristics and advantages of simple operation and system setting, high accuracy and fast measurement. Instructions Preface It is important to start the inspection. Fill the instrument with the grain to be inspected, for example, if there are three barrels, fill the longest barrel first, assemble and unload it into the next barrel, and use the blade-shaped thing to separate the excess grain. Pour it out and finally weigh it. It is the weight. Determination method of bulk density of folded corn A1 Instruments and appliances A1.1GHCS-1000 type weighing device (the lower diameter of the funnel is 40mm). A1.2 Grain selection sieve: The upper screen diameter is 12.0mm and the lower screen diameter is 3.0mm. A2 Sample preparation Divide the average sample from the original sample into two parts, take an average sample of about 1000g, and set the sieve layer according to A1.2 for two times. Take the upper sieve of the lower sieve and mix it as a sample for measuring the bulk density. A3 Installation and determination of weighing device A3.1 Open the lid of the box, take out all the components, and select the funnel according to the grain type. A3.2 Place the weighing cylinder with exhaust mound on the Electronic Scale, and adjust the zero point when it is empty. A3.2 Remove the volume, install the volume cylinder on the iron plate base, and put on the middle cylinder. A3.4 Pour the prepared sample into the grain drum, fill it up and level it. Then put the cereal drum on the middle drum, turn on the funnel switch, let the corn fall freely, and after all the samples fall into the volume drum through the middle drum, turn off the funnel switch. Hold the joint of the grain barrel and the middle barrel with your hand, insert the insert into the notch groove accurately, remove the grain barrel in turn, pick up the middle barrel and the volume cylinder, pour out the excess sample on the insert, and withdraw the insert , Remove the iron plate base on the volume cylinder, place the volume cylinder on the electronic scale and weigh. The allowable difference between the two tests does not exceed 3g / L, and the average number is the measurement result.
