Description

Technical Field

[0001] This invention relates to the field of coal quality testing technology, specifically to an online coal quality analysis and testing device. Background Technology

[0002] Coal quality testing is the process of systematically analyzing the physical, chemical, and technological properties of coal to determine its quality, suitability, and economic value. After coal mining, testing equipment is needed to assess the quality of the coal.

[0003] A search revealed a Chinese patent with application number "CN202411648360.2", which specifically describes an online coal quality detection system for power plants. The system includes a conveyor belt for transporting coal, a fixed frame fixedly installed above the conveyor belt frame, and a detector fixedly installed through the fixed frame, with the detector and conveyor belt positioned vertically opposite each other. The system also includes: a drive assembly installed on the upper surface of the fixed frame; a pressing assembly located inside the fixed frame, which flattens the coal through the drive assembly; a leveling assembly movably installed on the lower surface of the fixed frame; and a cleaning assembly located on the lower surface of the fixed frame, positioned on the outer side of the lower end of the detector.

[0004] The aforementioned patent uses a leveling component to level the transported coal and compact the coal sample to a fixed height, ensuring a constant distance between the detector lens and the coal surface and reducing signal errors caused by height differences. However, during leveling, the lower pressure plate presses down on the coal. When the leveled coal block is large, direct pressing can result in poor leveling effect of the pressure plate, increase the load on the pressure plate, and hinder subsequent detection.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides the following technical solutions: Example 1

[0029] Please see Figures 1-6 A coal quality online analysis and testing device includes a base plate 1. A mounting frame 2 and a fixing frame 4 are fixedly connected to the upper side of the base plate 1. A conveyor belt 3 is installed inside the mounting frame 2. A laser detection head 5 is fixedly connected to the upper side of the fixing frame 4. A hydraulic cylinder 6 is fixedly connected to the upper side of the fixing frame 4. A leveling unit 7 is installed at the lower output end of the hydraulic cylinder 6. The leveling unit 7 includes a lifting plate 72, which is fixedly connected to the lower output end of the hydraulic cylinder 6. A dispersing component 75 is installed below the lifting plate 72 to disperse large volumes of coal. A flattening component 76 is installed on the right side of the lifting plate 72. The conveyor belt 3 facilitates the transport of coal and the laser detection head 5 detects the coal. The coal is flattened before detection.

[0030] The dispersion component 75 includes a slide 751, which is located on the upper side of the lifting plate 72. Two symmetrically distributed sliders 752 are slidably connected to the inner side of the slide 751. A top plate 753 is fixedly connected to the upper side of each slider 752. U-shaped plates 754 are fixedly connected to the outer sides of both top plates 753. Multiple dispersion spikes 755 are fixedly connected to the lower sides of both U-shaped plates 754. Inclined plates 756 are rotatably connected to the upper sides of both the front and rear ends of the top plate 753. Rotating blocks 757 are rotatably connected to the outer sides of the inclined plates 756. Reciprocating blocks 758 are fixedly connected to the outer sides of the rotating blocks 757 on both the front and rear sides. A guide plate 7510 is fixedly connected to the upper side of the lifting plate 72. A guide block 759 is slidably connected to the outer side of the guide plate 7510. The guide block 759 is fixed to the reciprocating block 758. The hydraulic cylinder 6 is connected to a fixed plate 73 on the outer side of its output end. A rotating shaft 7512 is rotatably connected to the outer side of the fixed plate 73. The lower end of the rotating shaft 7512 passes through the lower side of the fixed plate 73 and is fixedly connected to a rotating plate 7513. A second inclined plate 7514 is rotatably connected to the lower side of the rotating plate 7513. A connecting block 7515 is rotatably connected to the outer side of the second inclined plate 7514. An L-shaped plate 7516 is fixedly connected to the rear side of the connecting block 7515. The L-shaped plate 7516 is fixedly connected to the reciprocating block 758. A telescopic rod 74 is fixedly connected between the fixed plate 73 and the fixed frame 4. A bevel gear 7517 is fixedly connected to the upper end of the rotating shaft 7512. A fixed block 7519 is fixedly connected to the upper side of the fixed plate 73. A rotating rod 7519 is rotatably connected to the outer side of the fixed block 7519. 18 and rotating rod 7521, the front end of rotating rod 7518 is fixedly connected to bevel gear 7523 which meshes with bevel gear 7517, the rear end of rotating rod 7518 is fixedly connected to gear component 7520, the rear end of rotating rod 7521 passes through the rear side of fixed block 7519 and is fixedly connected to gear component 7522 which meshes with gear component 7520, and the upper side of mounting bracket 2 is fixedly connected to toothed plate 71 which meshes with gear component 7522. Before testing, control hydraulic cylinder 6 drives lifting plate 72 to descend, lifting plate 72 drives the dispersing spikes 755 on both sides to descend, so that multiple dispersing spikes 755 pierce the large volume of coal, causing the large volume of coal to crack into smaller volumes of coal. At the same time, lifting plate 72 drives fixed plate 73 to descend. The fixed plate 73 drives the second gear component 7522 to descend, and the second gear component 7522 meshes with the gear plate 71, causing the second gear component 7522 to rotate. The second gear component 7522 drives the first gear component 7520 to rotate. Since the second gear component 7522 is a large gear and the first gear component 7520 is a small gear, it plays an accelerating role. The first gear component 7520 drives the first rotating rod 7518 to rotate, the first rotating rod 7518 drives the second bevel gear 7523 to rotate, the second bevel gear 7523 drives the first bevel gear 7517 to rotate, the first bevel gear 7517 drives the rotating shaft 7512 to rotate, the rotating shaft 7512 drives the rotating plate 7513 to rotate, the rotating plate 7513 drives the second inclined plate 7514 to rotate, and the second inclined plate 7514 drives the reciprocating block 758 on the L-shaped plate 7516 to move back and forth.The reciprocating block 758 drives the inclined plate 756 to rotate. Since the inclined plates 756 on both sides are symmetrically distributed, they cause the top plate 753 to move. The top plates 753 on both sides move towards each other, which in turn drives the U-shaped plate 754 to move. The U-shaped plate 754 then drives multiple dispersed spikes 755 to move, causing these spikes on both sides to move repeatedly towards each other. This rapidly expands and breaks the pierced coal into smaller pieces, facilitating subsequent leveling. Example 2

[0031] Based on Example 1, such as Figures 7-9 As shown, an online coal quality analysis and testing device includes a base plate 1. A mounting frame 2 and a fixing frame 4 are fixedly connected to the upper side of the base plate 1. A conveyor belt 3 is installed inside the mounting frame 2.

A leveling unit 7 is installed at the lower output end of the hydraulic cylinder 6. The leveling unit 7 includes a lifting plate 72, which is fixedly connected to the lower output end of the hydraulic cylinder 6. A dispersing component 75 is installed below the lifting plate 72 to disperse large volumes of coal. A flattening component 76 is installed on the right side of the lifting plate 72. The conveyor belt 3 facilitates the transport of coal and the laser detection head 5 detects the coal. The coal is flattened before detection.

[0032] The dispersion component 75 includes a slide groove 751, which is formed on the upper side of the lifting plate 72. Two symmetrically distributed sliders 752 are slidably connected to the inner side of the slide groove 751. A top plate 753 is fixedly connected to the upper side of each slider 752.

The outer sides of the inclined plates 756 are rotatably connected to… There is a rotating block 757, and reciprocating blocks 758 are fixedly connected to the outer sides of the rotating blocks 757 on both the front and rear sides. A guide plate 7510 is fixedly connected to the upper side of the lifting plate 72, and a guide block 759 is slidably connected to the outer side of the guide plate 7510. The guide block 759 is fixedly connected to the reciprocating blocks 758. A fixing plate 73 is fixedly connected to the outer side of the output end of the hydraulic cylinder 6. A rotating shaft 7512 is rotatably connected to the outer side of the fixing plate 73. The lower end of the rotating shaft 7512 passes through the lower side of the fixing plate 73 and is fixedly connected to a rotating plate 7513. A second inclined plate 7514 is rotatably connected to the lower side of 7513. A connecting block 7515 is rotatably connected to the outer side of the second inclined plate 7514. An L-shaped plate 7516 is fixedly connected to the rear side of the connecting block 7515. The L-shaped plate 7516 is fixedly connected to the reciprocating block 758. A telescopic rod 74 is fixedly connected between the fixed plate 73 and the fixed frame 4. A bevel gear 7517 is fixedly connected to the upper end of the rotating shaft 7512. A fixed block 7519 is fixedly connected to the upper side of the fixed plate 73. The outer side of the fixed block 7519 rotates... The rotating rod 7518 and the rotating rod 7521 are connected. The front end of the rotating rod 7518 is fixedly connected to the bevel gear 7523, which meshes with the bevel gear 7517. The rear end of the rotating rod 7518 is fixedly connected to the gear component 7520. The rear end of the rotating rod 7521 passes through the rear side of the fixing block 7519 and is fixedly connected to the gear component 7522, which meshes with the gear component 7520. The upper side of the mounting bracket 2 is fixedly connected to the toothed plate 71, which meshes with the gear component 7522.

[0033] The flattening assembly 76 includes a side plate 761, which is fixedly connected to the front and rear sides of the lifting plate 72. A connecting plate 762 is fixedly connected between the front and rear sides of the lifting plate 72. Two guide rails 767 are fixedly connected to the lower side of the connecting plate 762. Moving blocks 768 are slidably connected to the inner side of the guide rails 767. A moving plate 769 is fixedly connected between the two moving blocks 768. A connecting rod 7610 is fixedly connected to the lower side of the moving plate 769. A pressing plate 7611 is fixedly connected to the lower end of the connecting rod 7610. A control plate 765 is fixedly connected to the right side of the moving plate 769. A reciprocating plate 764 is fixedly connected to the upper side of the control plate 765. The reciprocating plate 764 is fixedly connected to a U-shaped plate 754. Multiple heating rods 766 are provided inside the connecting plate 762. When the heating rods 766 are activated, they heat the pressing plate 7611, causing... When the pressing plate 7611 comes into contact with the coal, it heats the coal to prevent excessive moisture from adhering to the pressing plate 7611. When piercing large volumes of coal, the lifting plate 72 lowers the side plate 761, which in turn lowers the connecting plate 762, which in turn lowers the pressing plate 7611. This facilitates the pressing plate 7611 pressing and leveling the coal. During leveling, the U-shaped plate 754 moves the reciprocating plate 764 left and right, which in turn moves the control plate 765, which in turn moves the moving plate 769, which in turn moves the connecting rod 7610. The connecting rod 7610 then moves the pressing plate 7611 left and right repeatedly, increasing the leveling effect as the pressing plate 7611 presses and flattens the coal.

[0034] Metal plates 7511 are fixedly connected to the outer sides of the reciprocating blocks 758 on both the front and rear sides. Metal blocks 763 are fixedly connected to the upper side of the connecting plate 762 and on both the front and rear sides of the metal plates 7511. The lower horizontal plane of the pressing plate 7611 is at the same level as the lower horizontal plane of the U-shaped plate 754. When piercing large volumes of coal, the reciprocating blocks 758 drive the metal plates 7511 to move back and forth. The metal plates 7511 impact the metal blocks 763, generating vibration, which cleans the coal dust adhering to the pressing plate 7611.

[0035] Working principle: During operation, coal is placed on conveyor belt 3 for transport. Hydraulic cylinder 6 then lowers lifting plate 72, which in turn lowers the dispersing spikes 755 on U-shaped plate 754, facilitating piercing of large volumes of coal. Simultaneously, lifting plate 72 lowers gear component 7522. Under the action of toothed plate 71, gear component 7522 drives gear component 7520 to rotate, which in turn rotates rod 7518 and bevel gear 7520. 23. Under the action of bevel gear 7517, the rotating shaft 7512 is controlled to rotate. The rotating shaft 7512 drives the rotating plate 7513 to rotate. The rotating plate 7513 drives the inclined plate 7514 to rotate. The inclined plate 7514 drives the reciprocating block 758 on the L-shaped plate 7516 to move. Under the action of inclined plate 756 and top plate 753, the U-shaped plates 754 on both sides are controlled to move repeatedly towards each other. The U-shaped plates 754 drive the dispersing spikes 755 to move repeatedly towards each other, so that the large volume of coal can be quickly moved. The coal is pierced into small pieces for easier flattening later. Simultaneously, the lifting plate 72 lowers the side plate 761, which in turn lowers the connecting plate 762, which in turn lowers the pressing plate 7611. This facilitates the pressing plate 7611 pressing the coal down. Meanwhile, the U-shaped plate 754 moves the reciprocating plate 764. Under the control of the control plate 765, the moving plate 769, and the connecting rod 7610, the pressing plate 7611 moves repeatedly left and right. At the same time, the reciprocating block 758 causes the metal plate 7511 to collide with the metal block 763, generating vibration and increasing the flattening effect. This also cleans the coal ash adhering to the pressing plate 7611. The metal blocks 763 are distributed on both sides of the connecting plate 762. The vibration generated by the collision of the metal blocks is transmitted to the pressing plate 7611 below. This vibration causes the coal particles to undergo high-frequency micro-displacement, breaking the "locked" state of static friction, reducing the shear resistance between particles, and increasing the flattening effect.
