Description

Technical Field

[0001] This utility model belongs to the field of coal mine sampling technology and relates to an on-site coal sampling device. Background Technology

[0002] Coal sampling upon arrival is a crucial step in the quality control process for coal receiving at a coking plant. The coal delivered to the coking plant is not uniform in quality; therefore, samples should be taken from different parts of the incoming coal. The original samples are then mixed, crushed, and reduced in size before being used for analysis and testing.

[0003] A mechanized coal sampling device for entering the site is disclosed in Chinese patent CN215339051U. The sampling device includes a support frame, a crossbeam, a moving block, a pulley, a motor, a hydraulic rod, a sampling arm, a sampling tube, a second motor, a slide rail, a connecting rail, a locking pin, a fixing hole, and a control plate.

[0004] The existing sampling device described above requires the sampling tube to be installed inside the sampling arm and fixed with a clip. After sampling, the sampling tube containing the sample is removed and a new sampling tube is installed. This results in the need to remove and place the sampling tube multiple times to meet the requirements when continuous sampling is needed, leading to low work efficiency.

[0005] To address the aforementioned problems, this utility model proposes an in-field coal sampling device. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an on-site coal sampling device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coal sampling device for entering the site includes a support frame, a hydraulic rod is movably arranged at the top of the support frame, an insertion rod is fixedly connected to the telescopic end of the hydraulic rod, a plurality of sampling chambers are evenly opened around the axis of the insertion rod at the bottom outer side, a cone is rotatably arranged at the bottom end of the insertion rod, a sampling port is opened on the cone, the sampling port corresponds to the sampling chamber, and a cleaning component for cleaning the sampling chamber is arranged inside the insertion rod.

[0008] Preferably, a slide rail is provided on the top crossbeam section of the support frame, a drive component is installed on the outside of the slide rail, and a hydraulic rod is fixedly installed at the bottom end of the drive component.

[0009] Preferably, a controller is fixedly installed on the side wall of the support frame.

[0010] Preferably, a motor is fixedly installed at the bottom end of the insertion rod, and the output shaft of the motor is fixedly connected to the cone.

[0011] Preferably, a blocking block is fixedly installed at the bottom end of the insertion rod, and the blocking block is located between multiple sampling chambers.

[0012] Preferably, the cleaning component includes a water supply channel, spray nozzles, and a connecting pipe. The water supply channel is fixed inside the insertion rod, and spray nozzles are provided at the bottom of the water supply channel corresponding to the positions of multiple sampling chambers. The spray nozzles are connected to the interior of the sampling chambers. The connecting pipe is fixed to the top of the insertion rod and is connected to the interior of the water supply channel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This coal sampling device uses a motor to drive the cone to rotate, thereby aligning the sampling port with each sampling chamber in sequence. This ensures that when the next sampling chamber opens, the others remain closed, avoiding the hassle of changing the sampling cylinder for each sampling. This not only prevents samples from different locations from mixing but also helps improve sampling efficiency.

[0015] 2. The coal sampling device at the site uses a water supply channel and spray nozzles to flush the inside of the sampling chamber. Then, the motor is rotated to continuously align the sampling port with each sampling chamber, thereby flushing out the coal slag inside the sampling port and avoiding interference with the next sampling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: As Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: a coal sampling device for entering the site, including a support frame 1, and a hydraulic rod 5 is movably arranged at the top of the support frame 1.

[0024] Specifically, a slide rail 3 is provided on the top crossbeam section of the support frame 1, a drive component 4 is installed on the outside of the slide rail 3, and a hydraulic rod 5 is fixedly installed at the bottom end of the drive component 4.

[0025] A controller 2 is fixedly installed on the side wall of the support frame 1.

[0026] The drive component 4 is a common existing technology. The drive component 4 is electrically connected to the controller 2, and the controller 2 can control the drive component 4 to move on the slide rail 3.

[0027] A plunger 6 is fixedly connected to the telescopic end of the hydraulic rod 5. Multiple sampling chambers 9 are evenly distributed around the axis of the plunger 6 at the bottom outer side. A cone 7 is rotatably provided at the bottom end of the plunger 6.

[0028] Specifically, a motor 10 is fixedly installed at the bottom of the insertion rod 6, and the output shaft of the motor 10 is fixedly connected to the cone 7. The motor 10 is electrically connected to the controller 2, and the controller 2 can control the start and stop of the motor 10.

[0029] The cone 7 has a sampling port 8, which corresponds to the sampling chamber 9.

[0030] A blocking block 11 is fixedly installed at the bottom of the insertion rod 6, and the blocking block 11 is located between multiple sampling chambers 9. The blocking block 11 can completely block the sampling port 8.

[0031] Working principle:

[0032] When not in use under normal circumstances, the sampling port 8 is aligned with the blocking block 11, and the inner wall of the cone 7 seals the sampling chamber 9 to prevent foreign matter from entering the sampling chamber 9 and causing the inability to sample normally, while also preventing the sample from being contaminated by other foreign matter.

[0033] In use, when a vehicle carrying incoming coal passes under the slide rail 3 at the top of the support frame 1, the drive unit 4 drives the hydraulic rod 5 and the insertion rod 6 to move horizontally on the slide rail 3, so that the cone 7 moves above the incoming coal that needs to be sampled. Then, the hydraulic rod 5 is activated, so that the hydraulic rod 5 drives the cone 7 to move downward through the insertion rod 6, so that the cone 7 is inserted into the interior of the incoming coal. Then, the motor 10 is activated, and the motor 10 drives the cone 7 to rotate, so that the sampling port 8 rotates from the position of the block 11 to the adjacent sampling chamber 9. The sampling port 8 and the sampling chamber 9 coincide, so that the incoming coal can enter the corresponding sampling chamber 9.

[0034] Then, motor 10 stops rotating, hydraulic rod 5 retracts, and the retracted hydraulic rod 5 drives the insertion rod 6 and cone 7 upward, causing cone 7 to move away from the incoming coal. Then motor 10 rotates again, aligning sampling port 8 with the next sampling chamber 9, while simultaneously sealing the inner wall of cone 7 against the already sampled sampling chamber 9 to prevent sample mixing when sampling at the next location. Subsequently, the vehicle moves, moving the next batch of incoming coal to be sampled below cone 7, allowing for sampling again, thereby improving sampling efficiency and preventing sample mixing.

[0035] Example 2: As Figures 2-3 As shown, the difference between this embodiment and Embodiment 1 is that the insert rod 6 has a cleaning component for cleaning the sampling chambers 9. The cleaning component includes a water supply channel 12, spray nozzles 13, and a connecting pipe 14. The water supply channel 12 is fixed inside the insert rod 6, and spray nozzles 13 are provided at the bottom of the water supply channel 12 at positions corresponding to multiple sampling chambers 9. The spray nozzles 13 communicate with the interior of the sampling chambers 9. The connecting pipe 14 is fixed to the top of the insert rod 6 and communicates with the interior of the water supply channel 12.

[0036] Working principle:

[0037] The difference between this embodiment and embodiment 1 is that the inside of the sampling chamber 9 can be rinsed during operation, while the rest of the working process is the same as that of embodiment 1.

[0038] After all the samples are taken out, they are connected to the water source through the connecting pipe 14, and water is supplied into the connecting pipe 14. The water is flushed through the water supply channel 12 and the spray hole 13 to rinse the inside of the sampling chamber 9. Then the motor 10 is rotated to make the sampling port 8 continuously align with each sampling chamber 9, thereby flushing out the coal slag inside the sampling chamber 9 to avoid interfering with the next sampling.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
