On-line detector for corn bulk density and its detection method

Abstract

The invention discloses an online corn bulk weight detector and a detection method thereof. The online corn bulk weight detector comprises a fixed volume grain discharging mechanism and an automatic turning and weighing mechanism arranged in a receiving hopper, wherein the fixed volume grain discharging mechanism comprises a grain discharging plate rack; a grain discharging roller is rotationally arranged in the grain discharging plate rack; fan-shaped grooves of the same volume are uniformly distributed on the peripheral outer wall of the grain discharging roller; a power source is arranged on one side of the grain discharging plate rack and is in transmission connection with one end of the grain discharging roller; a counting component is arranged between the other side of the grain discharging plate rack and the grain discharging roller; a limiting bottom plate is obliquely arranged in the grain discharging plate rack and is positioned behind the grain discharging roller; the automatic turning and weighing mechanism comprises a connecting base, and two pressure sensors are symmetrically fixedly arranged on the connecting base; and a semicircular tipping bucket in the middle of which a separator is arranged is hinged to a connecting bracket and is fixedly supported on the two pressure sensors by virtue of the connecting bracket. The online corn bulk weight detector has the advantages that the degree of automation is high, manual operation is not needed, the control precision is high, the reliability is high, the corn bulk weight can be detected on line in real time, and the detection result is accurate and reliable.

Description

technical field [0001] The invention relates to a corn bulk density detection device, in particular to an online corn bulk density detector and a detection method suitable for use in the drying process of corn and other grains. Background technique [0002] As the standard of corn quality inspection, bulk density is a comprehensive symbol of domestic and foreign grain quality inspection, and it is also the main indicator of domestic and foreign grain grade judgment and grain process quality evaluation. GB1353-2009 "Corn" national standard, the quality index is determined by volume weight, which is the weight of grain grains per unit volume (g / L), which is related to the maturity, yield and nutritional content of corn, and can be used as a measure The indicator of corn quality is a comprehensive reflection of the shape, size, quality, uniformity, endosperm texture, and ventral groove depth of the kernel. Bulk density is also an international measurement index, which can refl...

Problems solved by technology

It is easy to operate, but it cannot measure continuously, it needs manual loading and unloading, and it cannot realize automatic measurement

[0005] Comprehensive analysis of the detection principle and process of the current bulk density detector generally has problems such as complex operation procedures, manual operation, and poor repeatability, which are not conducive to continuous measurement and error elimination
