Particle dispersing device

Abstract

The invention relates to a particle dispersing device. A motor is fixed at the lower part of the motor frame, and the output shaft of the motor penetrates upwards through the motor frame and is connected with a driving screw; the periphery of the driving screw is provided with a shaft sleeve, and a lifting screw sleeve is assembled on the driving screw and positioned in the shaft sleeve; the lifting screw sleeve is driven by the driving screw to move up and down in the shaft sleeve; the outer wall of the lifting screw sleeve is provided with a guide groove in the axial direction of the lifting screw sleeve, the inner wall of the shaft sleeve is provided with a vertical guide pin, and the guide pin is embedded in the guide groove and forms a slide fit with the guide groove; the top of the lifting screw sleeve is provided with a top plate, the top plate is a round flat plate, a planar elastic body is flatly spread on the upper surface of the top plate, and the edge of the planar elastic body is clamped on a bracket through a pressure plate; the upper end of a sensor mounting rack is fixed on the lower surface of the top plate; and a height sensor is installed at the lower end of the sensor mounting rack. The device has ingenious and reasonable structure and can uniformly disperse the particle sample, so that the sample is arranged in the form of single particles and the food sample particles do not adhere to each other.

Description

technical field [0001] The invention relates to a device for inspecting and analyzing grain quality, in particular to a granular material dispersing device. Background technique [0002] my country is the world's largest grain producer and consumer. However, due to the large variety of domestic grains and the great difference in quality, it has caused great inconvenience for the classified storage, processing and quality inspection of grains. In recent years, the country attaches great importance to the quality of grain, and has newly formulated and revised many new national standards, such as GB 1350 "Paddy", GB / T 17891 "High-quality Rice", and GB 1354 "Rice". The appearance quality index of grain is the key technical index for its classification and grading. In the corresponding standards, the index control is becoming more and more strict, and the grading classification is becoming more and more refined. The traditional analysis of grain quality has been using the metho...

Problems solved by technology

However, due to the interconnection and dependence of the pellets, the arrangement is messy, and it is not easy to judge. During the inspection, the grain pellets need to be manually spread and separated one by one, and counted and judged with the naked eye.

This kind of operation is not only time-consuming and laborious, but also greatly affected by the subjective consciousness of the inspectors, with low accuracy and poor repeatability, it is difficult to obtain objective and effective test results, and the accuracy and processability of the data are very poor. It is difficult to meet the quality analysis requirements of grain
