[0003] Before the existing coal is inspected, it is necessary to take samples at multiple points, and then the staff will reduce the samples until the appropriate amount of coal samples are obtained. When reducing the coal samples, the staff mostly stir the coal manually, and then use the cross reduction method to reduce the coal in batches. This method is not only inconvenient when reducing the coal, but also increases the workload of the staff, and takes a long time, which reduces the efficiency of sampling. Utility Model Content

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-4As shown, a sample collection device for coal inspection includes a separation shell 1, the inner cavity of the separation shell 1 is fixedly connected to a fixed plate 2, through grooves 3 are opened on both sides of the top of the fixed plate 2, and the inner cavity of the through groove 3 is hinged with a blocking plate 4. A discharge mechanism 6 is installed on one side of the separation shell 1, under which the obtained coal can be poured onto the surface of the fixed plate 2. The blocking plate 4 can be supported by the discharge mechanism 6, so that the blocking plate 4 will not rotate easily. When a part of the coal needs to be taken out, the blocking plate 4 can be rotated under the action of the discharge mechanism 6. After the blocking plate 4 is tilted, the coal on its surface Under the action of its own gravity, it will fall downward through the through slot 3 to reduce the coal for sampling. The inner cavity of the separation shell 1 is slidably connected with a collection box 5, which can receive the fallen coal, so as to facilitate the subsequent staff to recycle and use the coal. Guide grooves 14 are provided on both sides of the bottom of the inner cavity of the separation shell 1. The inner wall of the guide groove 14 is slidably connected to the collection box 5. Under this action, the collection box 5 can be limited, so that the collection box 5 will not easily have a large position deviation when moving, which effectively improves the stability of the collection box 5. A magnet 1 is embedded on one side of the separation shell 1 5. The material of the collection box 5 is iron. The magnet 15 is used in conjunction with the collection box 5. Under this action, the collection box 5 can be limited, so that the collection box 5 will not move easily when it does not need to move, which effectively improves the stability of the collection box 5. A servo motor 7 is bolted to one side of the separation shell 1. The output shaft of the servo motor 7 is fixedly connected to the spur gear 8. A mounting ring 9 is fixedly connected to the top of the inner cavity of the separation shell 1. The surface of the mounting ring 9 is rotatably connected to the gear ring 10. The gear ring 10 and the surface of the spur gear 8 are meshed with each other. Under this action, the servo motor 7 can drive the spur gear 8 to rotate when it rotates. Thereby, the mounting ring 9 can rotate at the same time, and the interior of the gear ring 10 is fixedly connected to the positioning frame 11, and the inner wall of the positioning frame 11 is fixedly connected to the stirring rod 12. There are several stirring rods 12, and the stirring rod 12 is used in conjunction with the fixed plate 2. With the cooperation of the gear ring 10, the positioning frame 11 and the stirring rod 12, the stirring rod 12 can stir and mix the coal that needs to be reduced, so that the sample can be more uniform, thereby improving the accuracy of coal detection. Not only does it not require manual mixing by staff, reducing the workload of staff, but it also improves the efficiency of reduction.

[0022] The discharging mechanism 6 includes a stepper motor 61 bolted to one side of the separation shell 1. The output shaft of the stepper motor 61 passes through the interior of the separation shell 1 and is rotatably connected to the inner wall of the penetration point. The output shaft of the stepper motor 61 is fixedly connected to a rotating rod 62. Cams 63 are fixedly connected to both sides of the surface of the rotating rod 62. The surface of the cam 63 is movably connected to the bottom of the blocking plate 4. Under this action, the blocking plate 4 can be supported by the cam 63, so that the blocking plate 4 will not rotate easily. When the coal on the surface of the blocking plate 4 needs to be removed, the contact point of the cam 63 and the blocking plate 4 can be changed by the cooperation of the stepper motor 61 and the rotating rod 62, so that the blocking plate 4 can be rotated to dump the coal on its surface into the interior of the collecting box 5. One end of the rotating rod 62 is fixedly connected to the bearing seat 13, and the other side of the bearing seat 13 is fixedly connected to the inner wall of the separation shell 1. Under this action, the rotating rod 62 can be supported, so that the rotating rod 62 can be more stable when rotating, to avoid the rotating rod 62 being unstable and affecting the supporting effect of the cam 63 on the blocking plate 4.

[0023] Working principle: First, pour the sample to be reduced on the surface of the fixed plate 2, and then turn on the servo motor 7. Under the action of the servo motor 7, the gear ring 10 can drive the positioning frame 11 to rotate through the cooperation of the spur gear 8, and the positioning frame 11 can cooperate with the stirring rod 12 to stir the coal on the surface of the separation shell 1, so that the coal can be more uniform, which not only reduces the workload of the staff, but also is more convenient. When reduction is required, turn off the servo motor 7 and turn on the stepper motor 61. Under the action of the stepper motor 61, the rotating rod 62 can drive the cam 63 to rotate, thereby changing the contact point between the cam 63 and the blocking plate 4, so that the blocking plate 4 rotates, thereby pouring the coal on the top of the blocking plate 4 into the inside of the collecting box 5, and then the blocking plate 4 is returned to its original position by the stepper motor 61, and the coal is stirred again. The coal is reduced in this way repeatedly until the sample amount of coal is obtained and it can be taken out.
