Grain intermittent sample collecting and separating device and method

Abstract

Grain intermittent sample collecting and separating device and method. The device includes a receiving box that is directly connected to a sample detector. A material homogenizing piston is arranged on the lower part the receiving box. Piston left and right push rods are respectively arranged on the two sides of the material homogenizing piston. An intermittent material separating mechanism is arranged on the bottom of the material homogenizing piston and includes a first and a second gears, wherein a homogenizing left push rod and a movable bottom plate push rod, at a fixed angle, are disposed on the first gear; a homogenizing right push rod is installed on a shaft of the second gear. The piston left and right push rods are respectively matched with the homogenizing left push rod and thehomogenizing right push rod to push out and in the homogenizing piston. A movable bottom plate is arranged on the bottom of the sample detector. One side of the movable bottom plate is hinged to a sample detector box body. A tensioning spring is disposed between the movable bottom plate and the sample detector box body. A movable bottom plate lever is disposed on the movable bottom plate and is matched with the movable bottom plate push rod arranged on the intermittent material separating mechanism.

Description

technical field [0001] The invention relates to a grain sampling and dividing device, in particular to a grain intermittent sampling and dividing device and method. Background technique [0002] Paddy fields in some areas are seriously polluted by heavy metals, so that the heavy metal content of the grains planted and harvested exceeds the standard. Before entering the warehouse, the grains with excessive heavy metal content must be separated out, and multiple grades need to be sorted out according to the different heavy metal contents. However, there is no A sampling and dividing device and method based on an automatic heavy metal content analysis camera to realize the detection of grains with different heavy metal content. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intermittent grain sampling and dividing device and method to realize automatic sampling and dividing of grains, and further realize detecti...
