[0021] Reference Figure 1-4 The present invention proposes a grain image acquisition device with automatic sample replacement, comprising: a grain storage tank 1 for storing grain, a collector 2 for image acquisition, a horizontally arranged sampling plate 3 and a driving mechanism 4 for driving the sampling plate 3 to rotate, wherein:
[0022] The sampling disk 3 is partitioned to form a plurality of sampling areas b arranged along its circumference, and each sampling area b is provided with a material trough. The grain storage tank 1 and the collector 2 are arranged along the circumferential spacing of the sampling disk 3, and the side wall of the grain storage tank 1 is provided with a cutout a adapted to the thickness of the sampling disk 3, the collector 2 is located above the sampling disk 3, and a fan-shaped plate 5 coaxial with the sampling disk 3 is provided below the collector 2, the upper surface of the fan-shaped plate 5 and the lower edge of the cutout a are located in the same plane, and the radial side edge of one side of the fan-shaped plate 5 is butted and fixed with the lower edge of one side of the cutout a, and a spacing is reserved between the radial side edge of the other side of the fan-shaped plate 5 and the lower edge of the other side of the cutout a to form a gap d. When performing the inspection operation, each sampling area b on the sampling plate 3 is rotated out from the incision a in turn and passes through the fan-shaped plate 5 and the collector 2, so that each sampling area b on the sampling plate 3 brings the grains in the grain storage tank 1 to the bottom of the collector 2 for inspection and then discharged from the gap d.
[0023] As can be seen from the above, the present invention provides a cutout a on the side wall of the grain storage tank 1, provides a fan-shaped plate 5 below the collector 2, and makes the fan-shaped plate 5 coaxial with the sampling disk 3, so that the radial side edge on one side of the fan-shaped plate 5 is docked and fixed with the lower edge on one side of the cutout a, and a gap is reserved between the radial side edge on the other side of the fan-shaped plate 5 and the lower edge on the other side of the cutout a to form a gap d; at the same time, the sampling disk 3 is divided into a plurality of sampling areas b along the circumference of the sampling disk 3, and a plurality of material troughs for single grains to enter are provided in each sampling area b, and during the rotation of the sampling disk 3, each sampling area b thereof rotates out from the cutout a according to the rotation direction into the bottom of the collector 2 and passes through the bottom of the collector 2, thereby achieving the purpose of automatic replacement of samples without stopping the image acquisition work.
[0024] Reference Figure 5 The trough is composed of a number of through holes c for single grains to enter, and each through hole c is used to limit the position of the grain to be tested in each sampling area to ensure the consistency of the image acquisition points for each detection, thereby effectively filtering out interference from non-image acquisition areas, filtering out detection noise, ensuring the reliability of detection results, and reducing the image processing and analysis time of the image collector, improving detection efficiency, and facilitating image comparison.
[0025] Reference Figure 6, the fan-shaped plate 5 is made of transparent material, and an auxiliary collector 6 is provided below the fan-shaped plate 5, so that the auxiliary collector 6 cooperates with the collector 2 to collect patterns on the front and back of the sample respectively. At the same time, in order to ensure the clarity of image collection, the collector 2 and the auxiliary collector 6 are staggered along the rotation direction of the sampling disk 3 in this embodiment, and a first baffle (not shown in the figure) opposite to the collector 2 and made of non-transparent material is provided below the fan-shaped plate 5, and a second baffle (not shown in the figure) opposite to the auxiliary collector 6 and made of non-transparent material is provided above the sampling disk 3, so that the first baffle is used as a background wall for image collection by the collector 2, and the second baffle is used as a background wall for image collection by the auxiliary collector 6; and when any sampling area b on the sampling disk 3 moves to the bottom of the collector 2, another sampling area b adjacent to the sampling area b is located above the auxiliary collector 6.
[0026] In addition, in this embodiment, a collecting box (not shown) is provided below the notch d to collect the grains dropped from the sampling plate 3 after the detection.
