[0039] Example 1

[0040] Combination Figure 1-Figure 8A sample collector of an automatically rotating coal sampling machine comprises a conveying assembly 1, a sampling assembly 2 is arranged at the upper end of the conveying assembly 1, and a supporting assembly 3 is arranged below the conveying assembly 1. The conveying assembly 1 comprises a conveying frame 11, and a motor A12 is installed on one side of the conveying frame 11 to provide power to a conveyor belt 13 so that the conveyor belt 13 can carry out coal conveying operations. The conveyor belt 13 is installed on the inner wall of the conveying frame 11 to transport the coal required for the operation of the thermal power plant to a designated position, and then a large amount of heat is generated through the combustion of the boiler, and then subsequent operations are carried out. The output end of the motor A12 passes through the conveying frame 11 and is fixedly connected to the conveyor belt 13. The inner wall of the conveying frame 11 is installed with a roller member 14. Multiple groups of roller members 14 are used to lift up both sides of the conveyor belt 13, so that the conveyor belt 13 forms a C shape, thereby holding the coal to be transported, preventing the coal on the conveyor belt 13 from falling when the conveyor belt 13 shakes during the transportation process, and reducing the amount of transportation loss.

[0041] The sampling assembly 2 includes a sampling frame 21, on which a through groove matching the sampling rod 25 is opened, so that the sampling rod 25 can perform a normal rotation sampling operation. The sampling frame 21 is fixedly installed on the upper surface of the conveying frame 11, and a feeding pipe 22 is installed on one side of the sampling frame 21 to transport the sampled coal blocks to the sample collecting bucket to complete the sample collecting operation. The upper surface of the sampling frame 21 is fixedly connected to a motor B24 to drive the sampling rod 25 to rotate so that it can perform a rotation sampling operation on the coal, and the motor B24 is connected to the control assembly in the control room. The control assembly can be used to set the time interval at which the motor B24 is started, thereby realizing a uniform collection operation of the coal, thereby realizing multiple sampling operations of the coal, so that the specific information of the batch of coal can be obtained more accurately.

[0042] A sampling rod 25 is fixedly connected to the output end of the motor B24 for performing intermittent collection operations on the coal transported on the conveyor belt 13. A scraper 26 is slidably connected to one end of the sampling rod 25. The scraper 26 is fixed to the sampling rod 25 by screws. Vibrating members 27 are provided on both sides of the sampling rod 25. Power is supplied to the vibrating members by the motor B24, so that after each sampling, the sampling rod 25 is hit to vibrate the sampling rod 25 to shake off the coal slag attached to the inside of the sampling rod 25 to prevent affecting the next sampling operation. The vibrating member 27 is fixedly mounted on the upper surface of the sampling frame 21.

[0043] The bottom surface of the conveyor frame 11 is fixedly connected with a support leg 111, which is specifically a hydraulic cylinder, supporting the entire device so that it can work normally, and allowing the operator to adjust the support leg 111 according to the specific conditions on site, so as to adjust the entire device to a suitable working angle. The roller member 14 includes a roller frame 141, and the roller frame 141 is fixedly installed on the inner wall of the conveyor frame 11. The upper end of the roller frame 141 is rotatably connected with a roller 142, and the outer surface of the conveyor belt 13 is movably connected to the roller 142, so that the roller 142 supports the conveyor belt 13, so that the two sides of the conveyor belt 13 are higher than the middle part, so that the conveyor belt 13 forms a C shape, which holds the conveyed coal and reduces the problem of part of the coal falling due to the vibration of the conveyor belt 13 itself during the movement, reduces the amount of damage caused by transportation, and can effectively prevent the sampling rod 25 from knocking off excess coal when sampling.

[0044] A splash plate 211 is fixedly connected to the lower end of the inner surface of the sampling frame 21 to prevent excess coal from falling during sampling. After the coal brought up by the sampling rod 25 falls onto the inclined splash plate 211, the coal falls back onto the conveyor belt 13. A buffer plate 23 is arranged inside the discharge pipe 22. A spring A231 is elastically connected between one side of the buffer plate 23 and the inner wall of the discharge pipe 22, so that the buffer plate 23 has a certain displacement space. A plurality of groups of protrusions 232 are fixedly connected to the other side of the buffer plate 23. When the sampling rod 25 rotates, the coal is thrown out, and the coal collides with the protrusions 232 to perform secondary crushing on the coal.

[0045] An impact ring 241 is fixedly connected to the output end of the motor B24, and the vibration member 27 includes a mounting plate 271, which is fixedly mounted on the upper surface of the sampling frame 21. A movable rod 272 is arranged on the upper end of the mounting plate 271, and one end of the movable rod 272 movably passes through the mounting plate 271 and extends to one side thereof. An impact block 273 is fixedly connected to one end of the movable rod 272, and a spring B274 is elastically connected between the mounting plate 271 and the impact block 273. The spring B274 is sleeved on the outer surface of the movable rod 272. The impact ring 241 matches the impact block 273. The impact ring 241 impacts the impact block 273, so that the impact block 273 compresses the spring B274 and the movable rod 272 also moves. After the impact ring 241 leaves, under the action of the spring B274, the movable rod 272 drives the impact block 273 to reset, so that the impact block 273 impacts the sampling rod 25 to make it vibrate, thereby shaking off the coal attached to the sampling rod 25 to prevent it from affecting the next round of sampling operations.

[0046] A sampling groove 251 is provided on the sampling rod 25 to store the sampled coal. A plurality of mounting holes 252 are provided on the sampling rod 25 to facilitate fixing the scraper 26 by screws as needed, thereby controlling the actual capacity of the sampling groove 251 through the scraper 26. A movable groove 253 is provided on the sampling rod 25. A baffle 261 is fixedly connected to one side of the scraper 26. The outer surface of the baffle 261 is slidably connected to the movable groove 253. The scraper 26 and the baffle 261 are used to seal the sampling groove 251, thereby controlling the volume of the sampling groove 251, thereby achieving control of the sampling amount each time. The supporting assembly 3 includes a barrel rack 31. A fixing ring 32 is fixedly connected to the upper surface of the barrel rack 31, and the barrel rack 31 is arranged below the output end of the discharge pipe 22 to fix the sample collecting barrel so that it can work stably during the sample collecting process.

[0047] Working principle: First, according to the type of coal transported by the conveyor belt 13 this time, whether it is single-roasted coal or mixed coal, the corresponding sample collecting barrel is placed on the barrel rack 31 for fixing. Then, it is determined how long it will take to transport the total amount of this batch of coal. Then, the screws are removed and the scraper 26 is pulled to adjust it to the appropriate position. The volume of the sampling trough 251 is controlled by the scraper 26 and the baffle 261. After the sampling is completed, the samples in the sample collecting barrel include the upper, middle and bottom positions of the batch of coal, so that the operator can better collect information on the batch of coal in the later stage.

[0048] After being prepared, the coal is transported through the conveyor belt 13. The number of times the motor B24 is started is controlled by the main control room, that is, the number of sampling times is controlled. The coal passes under the sampling rack 21 through the conveyor belt 13. When the motor B24 reaches the set time, it starts, and the sampling rod 25 is driven by the motor B24 to rotate. The sampled coal is temporarily stored in the sampling slot 251 and then thrown out. The thrown coal has a certain acceleration, and then collides with the protrusion 232 to break it. Finally, the sampled coal falls into the sample collecting barrel placed on the barrel rack 31 for collection.

[0049] When the motor B24 drives the sampling rod 25 to rotate, it will also drive the impact ring 241 to rotate. Because the contact surface between the impact block 273 and the impact ring 241 is an inclined surface, the impact ring 241 can more easily compress the impact block 273. When the impact block 273 compresses the spring B274, the movable rod 272 also moves outward. When the impact ring 241 moves away from the impact block 273, the impact block 273 hits the sampling rod 25 under the action of the rebound force of the spring B274 itself, causing it to vibrate, thereby shaking off the coal attached to the sampling rod 25 to prevent it from affecting the next round of collection operations.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
