The lower two sides of the regular rhombus structure use two carrier rods, the top end of the carrier rod is rotatably connected to the sliding sleeve, and the two meshingly connected gears are coaxially connected to the bottom end of the connecting rod and the top end of the carrier rod respectively.

[0010] Preferably, the top end of the carrier rod is rotatably arranged via a damping bearing.

[0011] Preferably, the bidirectional telescopic assembly includes a reverse threaded barrel, which is rotatably mounted on the surface of the wall panel.

[0015] 2.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Embodiment 1: A fusion spectrum detection device includes a regular rhombus structure, a bidirectional telescopic component, an X-ray emission module 2, an X-ray collection module 3, and a near-infrared emission and collection module 4.

[0026] like Figure 2 、 Figure 3 As shown, the regular rhombus structure includes a wall panel 1 and two upper sides and two lower sides. The upper two sides of the regular rhombus structure use two telescopic rods 11. The telescopic rod 11 is composed of a rod body and a rod tube in a plug-in manner. The two telescopic rods 11 are distributed in an inverted V shape. The bottom ends of the telescopic rods 11 are rotatably connected to the wall panel 1, and the tops of the telescopic rods 11 are hinged at the rhombus vertex. The lower two sides of the regular rhombus structure use two carrier rods 12. The two carrier rods 12 are distributed in an "eight" shape. The top ends of the carrier rods 12 are rotatably connected to the wall panel 1. The bottoms of the two carrier rods 12 do not contact and are tilted toward the bottom point of the rhombus. The bottom rotating part of the telescopic rod 11 on the same side and the top rotating part of the carrier rod 12 are coaxially mounted with gears 7. The two gears 7 are of the same size and are meshed with each other.

[0027] like Figure 2 、 Figure 3 As shown, the bidirectional telescopic assembly includes a reverse threaded barrel 8, the internal thread of the reverse threaded barrel 8 is divided into two parts, the internal threads of the two parts rotate in opposite directions, the reverse threaded barrel 8 is installed at the front center position of the wall panel 1 through a bearing, the top and bottom of the reverse threaded barrel 8 are reversely threaded to connect the two threaded rods 81, the top of the top threaded rod 81 is fixed to the swivel, the swivel is hinged to the top of the two telescopic rods 11 at the rhombus vertex, the bottom end of the bottom threaded rod 81 is fixed to the carrier 6, the carrier 6 is vertically slidably connected to the wall panel 1 through a vertical slide, the driving assembly includes a motor 83, the motor 83 is installed on the back of the wall panel 1, the output shaft of the motor 83 is fixed with a worm 84, the surface of the reverse threaded barrel 8 is fixed with a worm gear 82, the surface of the wall panel 1 is provided with a through groove, the worm gear 82 passes through the through groove and is meshed with the worm 84.

[0028] The X-ray emission module 2 is used in conjunction with the X-ray acquisition module 3. Both the X-ray emission module 2 and the X-ray acquisition module 3 are existing products. Their supporting high-voltage power supplies, data output terminals and other components are not described in detail here. The X-ray emission module 2 and the X-ray acquisition module 3 are respectively mounted on the surfaces of the two carrier rods 12, and the X-ray emission module 2 and the X-ray acquisition module 3 are both pointed to the bottom point of the diamond.

[0029] like Figure 2 As shown, the near-infrared emission and acquisition module 4 is composed of a near-infrared emitter, an infrared collector, a composite optical cable and an optical fiber probe, all of which are existing technologies and will not be described in detail here. The near-infrared emission and acquisition module 4 is mounted on the surface of the carrier 6, and the near-infrared emission and acquisition module 4 points vertically downward to the bottom point of the diamond.

[0030] like Figure 2 As shown, the ranging module 5 uses an ultrasonic ranging sensor. The ranging module 5 is installed on the surface of the carrier 6. The ranging module 5 is located on the side of the near-infrared emission and acquisition module 4 that meets the material. The ranging module 5 points vertically downward. The ranging module 5 is connected to the motor 83 through the controller.

[0031] like Figure 1 As shown, the overall outline of the device is a regular rhombus shape, the detection point is located at the bottom point of the rhombus, the X-ray emission module 2, the X-ray collection module 3, and the near-infrared emission and collection module 4 all point to the bottom point of the rhombus, the detection lines of the X-ray emission module 2 and the X-ray collection module 3 have the same angle n with the vertical line, the telescopic rod 11 and the upper threaded rod 81 converge at the rhombus vertex, the distances between the bottom point of the rhombus, the rhombus vertex and the horizontal midline are the same, both d, the angles between the telescopic rod 11 and the carrier rod 12 and the horizontal midline are the same, both g, and the distance between the near-infrared emission and collection module 4 and the bottom point of the rhombus is a fixed value t.

[0032] The motor 83 drives the worm 84 to rotate, and the reverse threaded barrel 8 is rotated by the meshing transmission of the worm 84 and the worm wheel 82. The reverse threaded barrel 8 threads push the upper and lower threaded rods 81 to synchronously contract or extend the same distance, so that the height change value of the near-infrared emission and acquisition module 4 is the same as the height change value of the rhombus vertex. When the height of the rhombus vertex changes, the telescopic rod 11 is driven to deflect the angle and adaptively extend and retract. The carrier rod 12 is synchronously deflected by the meshing transmission of the two gears 7. The telescopic rod 11 and the carrier rod 12 are synchronously expanded or contracted, keeping the X-ray acquisition module 3 and the X-ray emission module 2 on the surface of the carrier rod 12 adjusted to point to the bottom point of the rhombus.

[0033] The rapid detection method for mineral materials using fusion spectrum detection equipment is as follows: like Figure 4As shown, the fusion spectrum detection device is arranged above the conveyor belt, and the material to be tested is transported horizontally by the conveyor belt through the bottom of the detection device. The detection parts corresponding to the X-ray emission module 2, the X-ray sampling module 3, and the near-infrared emission and acquisition module 4 are concentrated at a point on the upper surface of the material to be tested, which is the bottom point of the diamond. The X-ray emission module 2, the X-ray sampling module 3, and the near-infrared emission and acquisition module 4 are started intermittently to detect the material to be tested at the same point at the same time; When performing the test, the X-ray emission module 2 is turned on to emit X-ray photons toward the test point. The X-ray acquisition module 3 collects the fluorescence spectrum generated by the mineral material under the X-ray, processes it, and sends it to the data analysis component. The X-ray is used to detect the metal element content in the mineral material, and the compound content is fed back through the metal element content to determine the ash content. Turn on the near-infrared emission and acquisition module 4 to emit infrared light vertically downward to the detection point, and collect the infrared light information reflected by the detection point, which is used to detect the organic matter content in the mineral material. Combined with the above-mentioned ash detection, the calorific value and other related characteristics of the mineral material can be comprehensively judged. The X-ray emission module 2, the X-ray acquisition module 3, and the near-infrared emission and acquisition module 4 are a point of convergence for mineral material detection, which greatly improves the accuracy of the detection data.

[0034] Since the convergence detection point of the X-ray emission module 2, the X-ray collection module 3, and the near-infrared emission and collection module 4 is located on the surface of the object to be measured, and the surface of the object to be measured conveyed by the conveyor belt may have different heights, it is necessary to adaptively adjust the position of the detection point according to the height change of the object to be measured. The specific method is as follows: The controller sets the near-infrared emission and acquisition module 4 to maintain a fixed distance t from the object to be measured. The front distance measurement module 5 detects the height of the object to be measured and feeds back the detection data to the controller. When the height of the object to be measured increases, it means that the bottom point of the diamond needs to be raised. The controller controls the motor 83 to drive the reverse threaded barrel 8 to rotate. The lower threaded rod 81 drives the carrier 6 to rise through the thread pushing, so that the distance measurement module 5 and the near-infrared emission and acquisition module 4 rise synchronously, and the distance between the near-infrared emission and acquisition module 4 and the surface of the object to be measured is adjusted to t; When the reverse threaded barrel 8 rotates, the upper threaded rod 81 is driven to descend, causing the rhombus vertex to descend to the same height. The telescopic rod 11 rotates, and the gear 7 engages to drive the carrier rod 12 to change its angle, keeping the telescopic rod 11 and the carrier rod 12 at the same angle with the horizontal midline. The X-ray emission module 2 and the X-ray collection module 3 adjust their angles to keep pointing to the bottom point of the rhombus, so that the detection point position gathered by the X-ray emission module 2, the X-ray collection module 3, and the near-infrared emission and collection module 4 is dynamically adjusted according to the change in the height of the object to be measured.

[0035] The top end of the carrier rod 12 is rotatably connected to the wall plate 1 through a damping bearing, and cooperates with the worm wheel 82 and the worm 84 as a transmission part, so that the carrier rod 12 has a certain anti-torsion damping force, thereby improving the angle stability of the X-ray emission module 2 and the X-ray collection module 3 and alleviating vibration.

[0036] The wavelength of near-infrared light is between 700 nanometers and 1.4 microns, and the wavelength of X-rays is between 0.01 and 10 nanometers. Therefore, the various signal data collected at the same point have minimal mutual influence, which can ensure the accuracy of the data and avoid the data differences between X-rays and near-infrared light measured at multiple points.

[0037] Example 2: A fusion spectrum detection device includes a regular rhombus structure, a bidirectional telescopic component, an X-ray emission module 2, an X-ray collection module 3, and a near-infrared emission and collection module 4.

[0038] The difference from the first embodiment lies in the composition of the regular rhombus structure, and the rest of the structure and function are the same.

[0039] like Figure 5 、 Figure 6 、 Figure 7 As shown, the regular rhombus structure includes a wall panel 1 and two upper sides and two lower sides. The wall panel 1 has horizontally extending sliding parts 14 on both sides. The sliding parts 14 are provided with sliding sleeves 15 on the outside for horizontal sliding. The upper two sides of the regular rhombus structure use two connecting rods 13, and the two connecting rods 13 are distributed in an inverted V shape. The bottom ends of the connecting rods 13 are rotatably connected to the sliding sleeves 15, and the tops of the connecting rods 13 are hinged at the rhombus vertex. The lower two sides of the regular rhombus structure use two carrying rods 12, and the two carrying rods 12 are distributed in an "eight" shape. The top ends of the carrying rods 12 are rotatably connected to the sliding sleeves 15. The bottoms of the two carrying rods 12 do not touch and are tilted toward the bottom point of the rhombus. The bottom rotating part of the connecting rod 13 on the same side and the top rotating part of the carrying rod 12 are coaxially mounted with gears 7. The two gears 7 are of the same size and are meshed with each other.

[0040] When adjusting the detection position upward, the lower threaded rod 81 drives the carrier 6 to rise, so that the ranging module 5 and the near-infrared emission and acquisition module 4 rise synchronously, and the distance between the near-infrared emission and acquisition module 4 and the surface of the object to be measured is adjusted to t. At the same time, the upper threaded rod 81 descends, so that the top of the rhombus drops to the same height, and the connecting rod 13 rotates, pushing the sliding sleeve 15 to slide along the sliding part 14. The angle of the carrier rod 12 changes through the meshing transmission of the gear 7, keeping the angles of the connecting rod 13 and the carrier rod 12 at the same level with the horizontal midline. The X-ray emission module 2 and the X-ray acquisition module 3 adjust their angles to keep pointing to the bottom point of the rhombus, so that the detection point position where the X-ray emission module 2, the X-ray acquisition module 3, and the near-infrared emission and acquisition module 4 converge is dynamically adjusted according to the change in the height of the object to be measured.

[0041] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
