[0011] (1) The present application uses a rotating plate to transport the coal sample to be tested to the testing point, and then turns on the electric telescopic cylinder so that the telescopic rod moves the laser detection head to the testing position, thereby causing the limit rod to squeeze the button. The laser detection head is turned on by pressing the switch, and the laser beam is irradiated onto the surface of the coal sample. The intensity and angle of the laser scattering are then measured to infer the ash content of the coal sample. This non-contact measurement can perform ash detection quickly, accurately, non-destructively and without pollution.

[0012] (2) The present application uses the pressure on the support plate when the coal falls to move the support plate, thereby driving the rotating rod to move, so that the other end of the rotating rod pushes the slider to move on the slide rod, thereby compressing the spring. The elastic force of the spring offsets the elastic force generated when the coal falls, so that the coal sample can be more stable when it falls, which is convenient for subsequent testing.

[0019] 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.

[0020] Example 1

[0021] See also Figure 1-4 , a coal ash detection device, comprising a base 1, a top of the base 1 is fixedly connected to a bracket 2, and a side of the bracket 2 is fixedly connected to a transport frame 3;

[0022] The detection mechanism includes a motor 4, which is fixedly connected to the base 1. The output shaft at the top of the motor 4 is fixedly connected to a rotating shaft 5, the top of the rotating shaft 5 is fixedly connected to a rotating plate 6, the top of the rotating plate 6 is fixedly connected to a limiting rod 7, and the top of the rotating plate 6 is fixedly connected to a storage frame 8. There are four groups of limiting rods 7 and storage frames 8, which are distributed in pairs at the top of the rotating plate 6 with the horizontal midline of the rotating plate 6 as the axis of symmetry. The bottom end of the bracket 2 is fixedly connected to an electric telescopic cylinder 9, and the electric telescopic cylinder 9 is slidably connected to a telescopic rod 10 on the side. The bottom end of the telescopic rod 10 is fixedly connected to a laser detection head 11. The laser detection head 11 is a sensor device used for laser measurement and detection. It usually consists of a laser transmitter, a receiver, and related optical components. The laser detection head achieves the purpose of measurement and detection by emitting a laser beam and receiving the reflected or scattered signal of the laser. The transport frame 3 penetrates the bracket 2 on the side of the bracket 2 and is fixedly connected to it. One end of the transport frame 3 that penetrates the bracket 2 is at the top of the storage frame 8 and has no connection with the storage frame 8. The side of the laser detection head 11 is fixedly connected to a connecting rod 12, and the side of the connecting rod 12 is fixedly connected to a press switch 13. The press switch 13 is a normally open press switch. When the button of this type of switch is not pressed, the circuit is in an open state and is not conductive. When the button of the switch is pressed, the circuit is closed and conductive, and after the button is released Disconnect again, a button 14 is provided at the bottom end of the press switch 13, and a display screen 15 is fixedly connected to the side of the bracket 2. In this application, the coal sample to be tested is transported to the detection point through the rotating plate 6, and then the electric telescopic cylinder 9 is turned on to make the telescopic rod 10 move the laser detection head 11 to the detection position, so that the limit rod 7 squeezes the button 14, and the laser detection head 11 is turned on by pressing the switch 13. The laser beam is irradiated to the surface of the coal sample, and then the intensity and angle of the laser scattering are measured to infer the ash content of the coal sample. This non-contact measurement can perform ash detection quickly, accurately, non-destructively and pollution-free.

[0023] When this embodiment is used, the coal to be inspected is placed on the transport rack 3 and then transported to the storage frame 8 through the transport rack 3. When the inspection coal in the storage frame 8 reaches the inspection amount, the motor 4 in the base 1 is started, and the motor 4 rotates the shaft 5, and then the shaft 5 drives the rotating plate 6 to rotate. As the rotating plate 6 rotates, the storage frame 8 moves with the coal to be inspected, and finally moves to the bottom end of the laser inspection head 11. At this time, the electric telescopic cylinder 9 at the bottom end of the bracket 2 is turned on to make the electric telescopic rod 10 move toward the storage frame 8, and at the same time push The laser detection head 11 moves. When the laser detection head 11 reaches the detection height, the press switch 13 connected to the side of the laser detection head 11 by the connecting rod 12 also moves accordingly, and finally the button 14 set at the bottom thereof contacts the limit rod 7 and is then squeezed, thereby turning on the laser detection head 11 by pressing the switch 13. Subsequently, the laser detection head 11 detects the coal in the storage frame 8, irradiates the surface of the coal sample with a laser beam, and then measures the intensity and angle of the laser scattering to infer the ash content of the coal sample, and then displays the ash data on the display screen 15.

[0024] Example 2

[0025] See also Figure 5 , on the basis of embodiment 1, a stabilizing mechanism is added, which includes a support plate 16, the support plate 16 is slidably connected to the storage frame 8, the bottom end of the support plate 16 is rotatably connected to a rotating rod 17, a sliding rod 19 is fixedly connected to the storage frame 8, and a slider 18 is slidably connected to the side of the slider 19. One end of the rotating rod 17 is rotatably connected to the bottom end of the support plate 16. When the coal sample falls, the impacted support plate 16 will move downward, thereby causing the rotating rod 17 to rotate and move downward, thereby causing its other end to rotate at the top of the slider 18 and push the slider 18 to move, and the other end is rotatably connected to the top of the slider 18. A spring 20 is fixedly connected to the side of the slider 18, and one end of the spring 20 is fixed to the slider 18. The side of the block 18 is fixedly connected to it, and the other end is fixedly connected to it on the inner wall of the storage frame 8. As the two sets of rotating rods 17 push the slider 18 to move, the slider 18 squeezes the springs 20 at both ends, and the elastic force of the springs 20 offsets the impact force generated, so that the coal sample can be more stable when it falls. This application uses the pressure on the support plate 16 when the coal falls to move the support plate 16, thereby driving the rotating rod 17 to move, so that the other end of the rotating rod 17 pushes the slider 18 to move on the slide rod 19, thereby compressing the spring 20. The elastic force of the spring 20 offsets the elastic force generated when the coal falls, which can make the coal sample more stable when it falls, and facilitate subsequent testing.

[0026] During use, based on Example 1, when the coal sample enters the storage frame 8 through the transport rack 3, the coal sample contacts the support plate 16, and then the support plate 16 moves downward. As the support plate 16 moves downward, the rotating rod 17 rotates and moves downward. At the other end of the rotating rod 17, it rotates at the top of the slider 18 and pushes the slider 18, moving toward the inner wall of the storage frame 8 on the slide bar 19, and compressing the spring 20 at the same time. As the sliders 18 at both ends compress the spring 20, the elastic force of the spring 20 can offset the pressure generated when the coal sample falls, so that the sample can be more stable when falling, which is convenient for subsequent testing. It can also play a stabilizing role during the rotation and transportation of the rotating plate 6.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
