Description

Placer gold classification system The present invention relates to a placer gold sorting system. Placer gold is fine gold particles that have been mixed into sand or gravel at the water's edge or underwater after gold ore has been crushed by weathering or erosion. Since placer gold is contained in small amounts in soil and is heavier in weight (density) than soil, coarse soil such as gravel is first separated, and then fine soil is shaken in water to wash away the soil, and only the heavy placer gold that sinks is collected. To collect placer gold based on this principle, a method is used in which coarse soil such as gravel is first separated, and fine soil is washed away with water to separate the placer gold contained in the soil; at this time, a manual pump may be used to wash away the soil with water. However, since these manual pumps must be operated directly by the user, there is a problem of accumulated fatigue when used for a long time, and the flow of soil and water discharged by the manual pump is weak, which has the disadvantage of reducing the efficiency of gold separation. FIG. 1 is a front view schematically illustrating an example of a placer gold sorting system according to one embodiment of the present invention. Figure 2 is a block diagram schematically illustrating an example of the control unit of Figure 1. Figure 3 is a diagram illustrating the HSL color model. FIGS. 4a to 4c are drawings illustrating an example of dividing H, S, and L data into multiple regions in a color plane. FIG. 5 is a schematic side view illustrating an example of a gold dusting system according to another embodiment of the present invention. FIG. 6 is a schematic side view illustrating an example of a placer gold sorting system according to another embodiment of the present invention. The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and/or features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various forms. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. In the following embodiments, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another component. In the following examples, singular expressions include plural expressions unless the context clearly indicates otherwise. In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and/or thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, and therefore the present invention is not necessarily limited to what is illustrated. In the following embodiments, the x-axis, y-axis, and/or z-axis are not limited to three axes in an orthogonal coordinate system and can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and/or z-axis may be orthogonal to each other, but may also refer to different directions that are not orthogonal to each other. Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description. Additionally, in this application, "part" may be a hardware component, such as a processor or circuit, and/or a software component executed by a hardware component, such as a processor. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings, and when describing with reference to the drawings, identical or corresponding components will be given the same reference numerals. FIG. 1 is a front view schematically illustrating an example of a placer gold sorting system according to one embodiment of the present invention. Referring to FIG. 1, a placer gold classification system (1) may include a supply unit (100) that supplies soil containing placer gold, an imaging device (200) that photographs the soil supplied from the supply unit (100), a control unit (300) that analyzes the image taken by the imaging device
