Description

Technical Field

[0001] The present invention relates to the technical field of ore detection, in particular to a handheld ore element analyzer. Background Art

[0002] Traditionally, field exploration for nonferrous metals involves field sampling by prospectors, which is then brought back to the laboratory for crushing, grinding, screening, and chemical analysis. Ore element analyzers are crucial for analyzing ore elements, detecting and analyzing the content of elements within the ore. For example, they provide precise quantitative analysis of silicon, manganese, phosphorus, copper, nickel, chromium, molybdenum, rare earth elements, magnesium, titanium, zinc, aluminum, lead, iron, and tungsten in iron, copper, manganese, and nickel ores. However, this method of ore element analysis presents challenges such as complex operation and lengthy analysis cycles.

[0003] To improve mineral exploration efficiency, portable ore analyzers have gained widespread use in recent years. When using a portable ore analyzer to test large rock masses, the instrument can be held directly against the rock wall. However, testing small, fragmented rock blocks often requires one hand to pick up the block and place it on the analyzer's probe while holding the analyzer with the other hand to read the data. During the actual testing and analysis process, the block can easily move with the operator's hand, resulting in inaccurate test results and significant errors. Furthermore, the operator's hand is easily exposed to the main beam from the instrument's emission window, generating radiation that can affect the operator's health. Summary of the Invention

[0038] See also Figure 1-12 The present invention provides a technical solution for a handheld mineral element analyzer, comprising an analyzer body 1. The analyzer body 1 comprises a main body, a handle mounted near the rear end of the main body, a display screen located at the rear end of the main body, and a probe window located at the front end of the main body. A rechargeable lithium battery is removably mounted at the bottom end of the handle. A slot 1.1 extending laterally is provided in the middle of the main body of the analyzer body 1. A groove-shaped housing 1.2 is provided at the front of each side wall of the analyzer body 1. Axial holes 1.3 are provided at the front ends of the top and bottom plates of the groove-shaped housing 1.2.

[0039] The middle portion of the double-ended telescopic mechanism 2 is fixedly mounted laterally within the middle portion of the analyzer body 1. The double-ended telescopic mechanism 2 comprises a transverse housing 2.1 fixedly mounted within the inner cavity of slot 1.1, a drive tube 2.3, and a transverse screw 2.4. The front portion of the transverse housing 2.1 is provided with a transverse hole 2.1.1 extending laterally. The drive tube 2.3 comprises a threaded sleeve 2.3.1 disposed within the inner cavity of the transverse hole 2.1.1, with internal threads on either side of the middle portion rotating in opposite directions. A ring 2.3.3 is fixedly mounted on the exterior of the threaded sleeve 2.3.1 and rotatably engaged with the transverse hole 2.1.1. Two transverse screws 2.4 are respectively threadedly mounted at opposite ends of the inner cavity of the threaded sleeve 2.3.1. The outer ends of the transverse screws 2.4 are rotatably mounted with lugs 2.4.1. A transmission mechanism is provided at the rear of the inner cavity of the transverse housing 2.1 to drive the drive tube 2.3 in rotation. The transmission mechanism specifically includes: Gear 1 (2.3.2) is fixedly mounted in the middle of the outer portion of threaded sleeve (2.3.1), with rings (2.3.3) fixedly mounted on either side of Gear 1 (2.3.2). A slot (2.1.2) is provided at the rear of transverse housing (2.1), within which transverse motor (2.2) is fixed. Gear 2 (2.5) is fixedly mounted on the power output shaft of transverse motor (2.2), meshing with Gear 1 (2.3.2). Transverse motor (2.2) drives Gear 2 (2.5), which in turn drives threaded sleeve (2.3.1) through Gear 1 (2.3.2), thereby synchronously driving transverse screws (2.4) on either side to perform transverse telescopic movement. A side cavity 2.1.3 is located within the inner cavity of slot 2.1.2, corresponding to one side of gear 2.5. A countersunk hole 2.1.4 is located on the outer wall of transverse housing 2.1, corresponding to slot 2.1.2.

In other words, side cavity 2.1.3 accommodates gear 2.5. The front portion of side cavity 2.1.3 communicates with transverse hole 2.1.1, allowing gear 2.5 to mesh with gear 1 2.3.2 through this connection. Hexagon socket head cap screw 2.6 secures transverse motor 2.2 within slot 2.1.2.

[0040] The longitudinal telescopic mechanism 3 comprises a longitudinal housing 3.1 mounted within the grooved housing 1.2, a prismatic internally threaded tube 3.2 that slides longitudinally within the center of the front portion of the longitudinal housing 3.1, and a screw drive mechanism disposed within the rear portion of the inner cavity of the longitudinal housing 3.1 and driving the longitudinal telescopic movement of the prismatic internally threaded tube 3.2. Specifically, a rotating shaft 3.1.3 is provided at the center of the top and bottom surfaces of the longitudinal housing 3.1, respectively, and is rotatably coupled to the first shaft hole 1.3. A prismatic cavity 3.1.1 is provided at the front center of the longitudinal housing 3.1, which is slidably coupled to the prismatic internally threaded tube 3.2. The rear end of the longitudinal housing 3.1 is provided with an ear plate 3.1.4 that is hingedly coupled to the ear seat 2.4.1. A slot 2 3.1.2 is provided at the rear end of the longitudinal housing 3.1, within which a longitudinal motor 3.4 is secured. A longitudinal screw 3.3, threadably coupled to the prismatic internally threaded tube 3.2, is fixedly coupled to the front end of the power output shaft of the longitudinal motor 3.4. That is, the longitudinal motor 3.4 rotates the longitudinal screw 3.3, which in turn drives the prismatic internally threaded tube 3.2 to telescope back and forth along the prismatic cavity 3.1.1. Furthermore, the lateral telescopic movement of the transverse screw 2.4 drives the longitudinal housing 3.1 to swing horizontally within the trough-shaped housing 1.2, thereby opening and closing the front end of the prismatic internally threaded tube 3.2.

[0041] A connecting stud 4.1 is fixed to the rear end of the spherical shell 4 and is threadedly sleeved with the front end of the prismatic internal threaded tube 3.2.

[0042] The positioning support 5 comprises an end block 5.1, with a short post 5.2 fixed to the middle of the rear wall of the end block 5.1. A ball 5.3 is fixed to the rear end of the short post 5.2. A ball groove 5.1.1 is provided on the inner side wall of the end block 5.1. The ball 2.3 is rotatably mounted within the spherical housing 4 on one side. The ball 2.4 is rotatably mounted within the ball groove 5.1.1. A socket 5.4.1 is provided on the inner side of the ball 2.4.

[0043] The drive support 6 comprises a second end block 6.1, with a second short post 6.2 fixed to the middle of its rear wall. A third sphere 6.3 is secured to the rear end of the second short post 6.2. A sleeve 6.1.1 is provided between the two side walls of the second end block 6.1, which is adapted to receive a tilting motor 6.4. The third sphere 6.3 is rotatably mounted within the spherical housing 4 on the other side. The power output shaft of the tilting motor 6.4, which is fixedly mounted within the inner cavity of the sleeve 6.1.1, faces inward, and a sleeve 6.5 is secured to the inner end of the power output shaft of the tilting motor 6.4.

[0044] Each chuck 7 comprises a center disk 7.1, a connecting shaft 7.2 fixed to the center of the center disk 7.1, and clamping flaps 7.3 circumferentially arranged around the outer edge of the center disk 7.1. The connecting shafts 7.2 of the two chucks 7 are respectively fixedly sleeved within the corresponding receptacles 5.4.1 or sleeves 6.5. The outer edges of the clamping flaps 7.3 converge inward and are flexible enough to ensure a snug grip on irregular ore samples.

[0045] In summary, when elemental detection and analysis is required for a fragmented ore sample, the longitudinal motors 3.4 on both sides are first started synchronously, so that the longitudinal screws 3.3 on both sides respectively drive the prismatic internal threaded tube 3.2 to extend forward, so that the chucks 7 on both sides are respectively placed on both sides of the ore sample to be detected.

[0046] Then, the transverse motor 2.2 is started, and the threaded sleeve 2.3.1 is driven to rotate through the meshing transmission of gear 2.5 and gear 1 2.3.2, so as to realize the synchronous extension of the transverse screw rods 2.4 on both sides, so that the front ends of the longitudinal housings 3.1 on both sides are synchronously swung inward, so that the chucks 7 on both sides can clamp and fix the ore sample to be tested.

[0047] Then, the longitudinal motors 3.4 on both sides rotate synchronously in opposite directions to achieve the synchronous contraction of the prismatic internally threaded tubes 3.2 on both sides. At the same time, the transverse motors 2.2 rotate accordingly to ensure that the prismatic internally threaded tubes 3.2 on both sides tend to swing inward while contracting backward, ensuring that the ore sample to be tested is continuously clamped and fixed. Until the ore sample to be tested is placed on the probe of the analyzer body 1, the elemental detection and analysis operation corresponding to the position of the ore sample to be tested is completed.

[0048] Then, the corresponding chuck 7 is driven to rotate by the turning motor 6.4, and the chuck 7 on the other side rotates accordingly, so as to realize a comprehensive detection and analysis operation on the ore sample to be tested.
