[0029] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1-6 Description of a coal quality testing sample-changeable radiation-proof elemental analyzer 100 according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the coal quality testing sample changer-type radiation-proof elemental analyzer 100 according to an embodiment of the present utility model includes: a testing box mechanism 10, a testing mechanism 20, a clamping mechanism 30, and a loading and unloading mechanism 40.

[0032] The detection box mechanism 10 mainly provides installation space for the detection mechanism 20, the clamping mechanism 30 and the loading and unloading mechanism 40; the detection mechanism 20 is mainly used to detect coal samples, the clamping mechanism 30 is suitable for fixing the coal samples to be tested; the loading and unloading mechanism 40 is mainly used for automatic loading and unloading of coal samples to realize the detection and replacement of coal samples.

[0033] Specifically, refer to Figures 1-3 The detection box mechanism 10 includes a box body 11, with a front-opening receiving cavity 111 formed inside the box body 11. A partition 12 that can slide in the vertical direction is arranged on the front side wall of the box body 11. The partition 12 is used to open and close the opening.

[0034] Specifically, when a coal sample needs to be placed at the testing position or when the coal sample needs to be replaced, the partition 12 opens, allowing the sample to be fed into or out of the receiving cavity 111. When testing is being performed or when testing is not required, the partition 12 closes the opening, creating a sealed space within the housing 11. This sealed space provides a stable testing environment, thereby improving the accuracy of the test results. Furthermore, it should be noted that some testing equipment emits radiation, which can be harmful to the human body. Therefore, the sealed space effectively prevents radiation from affecting the operators, thus enhancing their safety.

[0035] The testing mechanism 20 is arranged within the receiving cavity 111 and is used to test the coal sample to be tested. It should be noted that the testing mechanism 20 can be of various types, and the specific form can be selected according to the actual situation.

[0036] The clamping mechanism 30 includes a sample support plate suitable for placing the coal sample to be tested. It should be noted that the sample support plate can be a separate component or part of the clamping mechanism 30; there is no limitation here.

[0037] For example, the sample support plate can be a glass plate, and the coal sample to be tested can be placed on the glass plate to prepare a test piece. Then, the glass plate is clamped by the clamp 31 to fix the coal sample to be tested.

[0038] The loading and unloading mechanism 40 includes a pusher 41 and a slider 42. The slider 42 is connected to the pusher 41. The sample carrier plate is disposed on the slider 42. The pusher 41 is movable between a first position and a second position in the front-back direction. When the pusher 41 is in the first position, at least a portion of the sample carrier plate extends out of the opening. When the pusher 41 is in the second position, the pusher 41, the slider 42 and the sample carrier plate are all located in the receiving cavity 111, and the sample carrier plate is directly opposite the detection mechanism 20 in the vertical direction. When the pusher 41 moves between the first position and the second position, it pushes the partition 12 to open and seal the opening.

[0039] Specifically, when the pusher 41 is in the first position, the opening is open and part or all of the sample support plate extends out of the opening, which facilitates the placement or removal of the coal sample. When the pusher 41 is in the second position, the pusher 41, the sliding member 42 and the sample support plate are all located in the receiving cavity 111, the opening is closed, the box 11 is sealed, the sample support plate and the detection mechanism 20 are directly opposite each other in the vertical direction, and the detection mechanism 20 detects the coal sample in a sealed state.

[0040] Therefore, it can be understood that the elemental analyzer 100 of this embodiment can achieve automatic feeding through the loading and unloading mechanism 40, thereby solving the problem of the danger of directly putting samples into existing coal quality testing instruments.

[0041] Furthermore, in this embodiment, by moving the pusher 41 between the first position and the second position, automatic loading and unloading can be achieved, as well as automatic opening and closing of the partition 12. In other words, the loading and unloading mechanism 40 of the element analyzer 100 in this embodiment can integrate the loading and unloading action with the opening and closing function of the partition 12 into one, without the need for an additional independent drive mechanism. This simplifies the overall equipment structure and improves the degree of automation and operational reliability.

[0042] According to the present invention, the coal quality testing sample-changeable radiation-proof elemental analyzer 100, by setting up a loading and unloading mechanism 40, not only can the sample be automatically loaded and unloaded, but the partition 12 can also be driven to automatically open and close the opening, so that the coal sample can be tested under sealed conditions. This design not only effectively reduces the safety risks that may be caused by directly placing the sample, but also reduces the impact of radiation on the operator, thereby significantly improving the safety of operation. In addition, the structure of the loading and unloading mechanism 40 integrates multiple functions into one, thereby simplifying the overall mechanical layout of the equipment, while also improving the automation level of the elemental analyzer 100 and enhancing the operational reliability of the elemental analyzer 100.

[0043] According to some embodiments of this utility model, refer to Figure 4The pusher 41 extends in the front-to-back direction and has a push surface on the side facing the opening. In the upward direction, the push surface extends obliquely away from the opening. The push surface is adapted to abut against the partition 12 in the vertical direction to push the partition 12 to open and close the opening. It can be understood that when the pusher 41 moves from the second position to the first position, the push surface contacts the partition 12 and applies an oblique force, thereby pushing the partition 12 upward to open the opening. When the pusher 41 moves from the first position to the second position, the partition 12 falls back under gravity, and the pusher 41 acts as a guide, causing the partition 12 to slowly move back to its original position to close the opening. The oblique push surface of the pusher 41 allows for effective vertical displacement of the partition 12 simply by moving it back and forth, eliminating the need for an additional lifting drive mechanism. This simplifies the overall mechanical structure of the device and helps improve system stability and control efficiency.

[0044] According to some embodiments of this utility model, refer to Figure 3 The housing 11 has a guide groove 113 extending in the vertical direction, and the partition 12 is slidably fitted within the guide groove 113. It can be understood that the guide groove 113 can guide the movement trajectory of the partition 12, so that the partition 12 can move only in the vertical direction without deviating, thereby ensuring the accuracy of opening and closing the partition 12.

[0045] According to some embodiments of this utility model, refer to Figure 3 The housing 11 and the partition 12 each have a positioning protrusion 112 and a positioning groove 121. When the pusher 41 is in the second position, the positioning protrusion 112 engages with the positioning groove 121. It can be understood that if the housing 11 has a positioning protrusion 112, then the partition 12 has a positioning groove 121; conversely, if the housing 11 has a positioning groove 121, then the partition 12 has a positioning protrusion 112. When the pusher 41 is in the second position, the positioning protrusion 112 engages with the positioning groove 121, thus further positioning the partition 12 and ensuring that the partition 12 completely closes the opening. This achieves complete closure of the detection box mechanism 10, thereby further improving the safety of the detection.

[0046] According to some embodiments of this utility model, refer to Figure 4The loading and unloading mechanism 40 also includes a first drive motor 43, a lead screw 44, and a moving block. One end of the lead screw 44 is connected to the output end of the first drive motor 43. The moving block is sleeved on the lead screw 44 and threadedly engaged with it. The pushing member 41 is fixedly connected to the moving block. It can be understood that in the above embodiment, the first drive motor 43 drives the lead screw 44 to rotate, causing the moving block to perform linear reciprocating motion, thereby enabling the pushing member 41 to move between a first position and a second position in the front-back direction. The design of the first drive motor 43, lead screw 44, and moving block working together is compact, has high control precision, and operates stably, thus improving the movement stability of the pushing member 41.

[0047] It should be noted that the moving block and the pusher 41 are integrated into one piece. This can improve the structural compactness of the loading and unloading mechanism 40, reduce the overall size of the loading and unloading mechanism 40, and thus reduce the size of the entire analyzer.

[0048] Optional, for example Figure 4 As shown, the inspection box mechanism 10 also includes an inspection table 13, wherein the loading and unloading mechanism 40 is fixed on the inspection table 13, that is, the inspection table 13 can support the loading and unloading mechanism 40. Specifically, refer to... Figure 4 The loading and unloading mechanism 40 also includes a mounting component 45, and the first drive motor 43 is fixed on the testing table 13 through the mounting component 45.

[0049] According to some embodiments of this utility model, refer to Figure 4 The pushing component 41 includes a first pushing plate 411 and a second pushing plate 412, which are arranged at intervals in the left-right direction. A sliding component 42 is connected between the first pushing plate 411 and the second pushing plate 412. A first drive motor 43, a lead screw 44, and a moving block are all arranged on the side of the first pushing plate 411 or the second pushing plate 412 away from the sliding component 42. It can be understood that only one set of the first drive motor 43, the lead screw 44, and the moving block is included. That is, the embodiments of this application use one set of driving devices to realize the movement of the first pushing plate 411, the second pushing plate 412, and the sliding component 42. In this way, while ensuring the normal operation of the loading and unloading mechanism 40, the overall production cost of the equipment can also be reduced. In addition, the sliding component 42 is located between the two pushing plates, and the driving device is located on the side of the two pushing plates away from the sliding component 42. This can effectively avoid interference between the driving device and the sliding component 42, thereby ensuring the operational reliability of the entire equipment.

[0050] According to some embodiments of this utility model, refer to Figures 3-4The loading / unloading mechanism 40 also includes a first guide 46 and a second guide 47. The first guide 46 is fixed to the housing 11, and the second guide 47 is fixedly connected to the sliding member 42. One of the first guide 46 and the second guide 47 is formed as a slide rail extending in the front-back direction, and the other is formed as a slider, which is slidably engaged with the slide rail. It can be understood that the arrangement of the first guide 46 and the second guide 47 can limit the movement trajectory of the pushing member 41 and the sliding member 42, so that the pushing member 41 and the sliding member 42 can only move in the front-back direction, thereby ensuring the stability of the horizontal displacement of the loading / unloading mechanism 40. This improves the reliability and positioning accuracy of the entire machine.

[0051] The phrase "one of the first guide member 46 and the second guide member 47 is formed as a slide rail extending in the front-back direction, and the other is formed as a slider, with the slider slidably engaged on the slide rail" can be understood as follows: if the first guide member 46 is formed as a slide rail, then the second guide member 47 is formed as a slider, and vice versa. This slide rail-slider structure provides a very precise linear motion trajectory and is relatively simple in structure with a low coefficient of friction. Therefore, having one of the first guide member 46 and the second guide member 47 form a slide rail and the other a slider ensures the efficiency and stability of the equipment while reducing the overall production cost of the loading / unloading mechanism 40, extending the equipment's service life, and reducing maintenance costs.

[0052] According to some embodiments of this utility model, refer to Figure 6 The clamping mechanism 30 further includes: clamping plates 31, a transmission component, and a second drive motor 33. There are two clamping plates 31, which are slidable in the left-right direction on a sliding component 42. The two clamping plates 31 are adapted to clamp the sample support plate. The second drive motor 33 is connected to the clamping plates 31 via the transmission component to drive the two clamping plates 31 to move towards or away from each other in the left-right direction. Specifically, the second drive motor 33 provides driving force for the movement of the clamping plates 31, enabling them to move towards or away from each other in the left-right direction. When the two clamping plates 31 move towards each other, they are adapted to clamp the sample support plate, facilitating the movement of the sample to the detection position. When the two clamping plates 31 move away from each other, they are adapted to release the sample support plate, facilitating the replacement or installation of the sample support plate.

[0053] Optional, refer to Figure 6A clamping groove 311 is formed on one side of the clamping plate 31, which extends in the front-back direction. The sample support plate is suitable for being placed in the clamping groove 311. In this way, when installing or removing the sample support plate, one end of the sample support plate can fit into the clamping groove 311 on one side. The clamping groove 311 can support the sample support plate, thereby preventing the sample support plate from falling out. This is beneficial for the clamping plate 31 to hold the sample support plate. At the same time, the clamping groove 311 can also increase the contact area between the clamping plate 31 and the sample support plate, thereby improving the stability of the clamping plate 31 in holding the sample support plate and reducing the risk of the sample support plate falling out.

[0054] Optional, refer to Figure 6 The upper end of the sliding member 42 has a downward recessed groove, and the second drive motor 33 is fixed in the groove by the connecting block 34. This helps to reduce the overall size of the entire clamping mechanism 30, thereby reducing the overall size of the entire device.

[0055] According to some embodiments of this utility model, refer to Figure 6 The transmission component includes a gear and two first connecting members 32. The two first connecting members 32 are arranged rotationally symmetrically about the center of the gear, and each of the two first connecting members 32 is connected to two clamping plates 31. Each first connecting member 32 includes a rack portion adapted to mesh with the gear. It is understood that the meshing of the gear and rack enables the movement of the first connecting member 32, thereby driving the two clamping plates 31 to move towards or away from each other in the left-right direction, thus achieving horizontal clamping of the sample. The gear and rack transmission is relatively simple, easy to manufacture, and occupies little space. Therefore, including the gear and two first connecting members 32 in the transmission component reduces the manufacturing cost and transmission complexity.

[0056] It should be noted that the two first connecting parts 32 are arranged symmetrically about the center of the gear, and the two rack parts are respectively engaged with the upper and lower ends of the gear. In this way, the two first connecting parts 32 can move towards each other or away from each other in the left and right directions.

[0057] According to some embodiments of this utility model, refer to Figure 6 The clamping mechanism 30 further includes a third guide 35, which extends in the left-right direction and is connected to the sliding member 42. The first connecting member 32 is slidably disposed on the third guide 35. It is understood that the third guide 35 can guide the movement of the first connecting member 32 in the left-right direction, thus limiting the first connecting member 32 to movement only in the left-right direction, thereby achieving horizontal clamping of the sample.

[0058] According to some embodiments of this utility model, refer to Figure 4The detection mechanism 20 includes: a lifting component 21, a fixing component 22, an X-ray detector 23, and a detector collector 24. The fixing component 22 is fixed to the housing 11, and the lifting component 21 is movably connected to the fixing component 22 in the vertical direction. The X-ray detector 23 is adapted to be fixed to the lifting component 21, and a probe for detection is provided at the lower end of the X-ray detector 23. The detector collector 24 is arranged vertically and vertically corresponding to the probe. The lifting component 21 can drive the X-ray detector 23 to rise and fall to adjust the detection distance, thereby ensuring the accuracy of the detection. The X-ray detector 23 is mainly used to emit X-rays to the coal quality test sample, and the detector collector 24 is mainly used to collect and analyze the fluorescent X-rays of a specific wavelength excited at the location where the elements in the sample absorb X-rays, thereby completing the detection of the element content in the coal quality test sample.

[0059] Specifically, when a coal quality sample needs to be tested, the lifting component 21 is first moved to move the X-ray detector 23 to adjust the detection distance. Then, the detector is turned on. At this time, the probe of the X-ray detector 23 generates X-rays, which irradiate the coal quality sample. The elements in the sample absorb the X-rays and are excited to generate fluorescent X-rays of a specific wavelength. Then, the detector collector 24 collects these fluorescent X-rays and converts them into electrical signals. Then, by analyzing these electrical signals, the intensity of different elements is obtained. Then, based on the intensity of the elements and the known standard curve, the content of elements such as carbon, hydrogen, nitrogen, and sulfur in the sample is calculated.

[0060] According to some embodiments of this utility model, refer to Figures 1-3 The enclosure 11 has multiple vents 114 communicating with the receiving cavity 111 on at least one side wall in the left-right direction. It is understood that the multiple vents 114 can be formed on the left or right side wall of the enclosure 11, or on both side walls. The vents 114 are used for ventilation and heat dissipation, thereby ensuring the safe operation of the equipment inside the enclosure 11.

[0061] Optional, refer to Figure 3 The detection box mechanism 10 also includes a ventilation plate, which is fixed to the left or right side wall of the box body 11. Multiple air holes 114 are formed on the ventilation plate and arranged in a matrix on the ventilation plate. This facilitates production. At the same time, when the air holes 114 are blocked, only the ventilation plate needs to be replaced, thereby reducing the maintenance cost of the analyzer.
