Detailed Description
The invention is described in detail below with reference to the drawings and the detailed description, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1 to 2, an embodiment of the present invention provides a portable wood sample scanning support for a near-infrared spectrometer, the support is used for placing a wood standard sample to be detected, and the support includes a base 5, a support rod 4 fixedly connected to the base 5, and a screw 32 fixedly connected to one end of the support rod 4; the screw 32 extends vertically and penetrates through the hollow supporting seat 2, the nut 31 is fixedly connected with the supporting seat 2 and forms a transmission mechanism 3 together with the screw 32, the threaded part of the screw 32 penetrates through the nut 31, at least one penetrating groove is formed in the nut 31, and the size of the groove is matched with that of the threaded part of the screw 32, so that the assembly, disassembly and rotation are convenient; the top end of the supporting seat 2 is fixedly connected with the clamping device 1, and positioning round holes 11 are formed in the centers of four faces of the clamping device 1.
Clamping device 1 plays the fixed effect of timber prescription that will await measuring, and the different sections of timber sample can help discerning by the fretwork design simultaneously. Wood is an anisotropic material, which is extremely complex in its construction, and after cutting from different directions, there are typically three sections, namely: the cross section, the radial section and the chord section are vertical to the main shaft direction of the trunk, so that the cross section and the chord section are easy to identify by naked eyes, the radial section and the chord section are distinguished by wood grains, the radial section is parallel to wood rays through a medullary center, and the chord section is tangent to the growth wheel.
