Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to a coal sampling device. Background Technology

[0002] Most of the coal sampling machines currently in use are large machines that are difficult to move under normal circumstances. Moreover, once damaged, it means that the sampling work on this track cannot be completed and must be switched to another track. This is where the advantage of a detachable and movable sampling device comes into play. Common sampling equipment on the market has poor autonomy and is heavy. After sampling, multiple processes are required to transfer the sample, which wastes a lot of manpower and resources. Utility Model Content

[0003] The purpose of this invention is to provide a coal sampling device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A coal sampling device includes a sampling cylinder and a discharge pipe. A feeding auger is rotatably connected inside the sampling cylinder, and a drive motor is fixedly connected to the top of the feeding auger. A guide tube mounting groove is formed on the outer wall of the sampling cylinder near the bottom. A sampling guide tube is rotatably connected to the inner wall of the guide tube mounting groove via a shaft. A docking column is fixedly connected to one side of the sampling guide tube. A push rod is movably connected to the outer wall of the docking column, and a sampling push rod is rotatably connected to the top of the push rod.

[0006] The inner wall of the sampling cylinder near the bottom is provided with a feeding groove that connects to the bottom of the sampling guide tube. The top of the sampling cylinder is provided with a sampling rod groove for installing the sampling push rod. A push plate is fixedly connected to the top of the sampling push rod, and a hydraulic rod is fixedly connected to the upper surface of the push plate.

[0007] A further improvement of this utility model is that: the inner wall of the sampling rod groove is slidably connected to the outer wall of the sampling push rod, the top end of the hydraulic rod is fixedly connected to a mounting bracket, and the top of the inner wall of the mounting bracket is fixedly connected to the top of the drive motor by bolts.

[0008] A further improvement of this utility model is that the outer wall of the mounting frame is fixedly connected with a reinforcing support leg.

[0009] A further improvement of this utility model is that the number of sampling guide tubes is two sets, and the two sets of sampling guide tubes are symmetrically distributed on both sides of the bottom end of the sampling cylinder.

[0010] A further improvement of this utility model is that the inner wall of the sampling rod groove is slidably connected to the outer wall of the sampling push rod, and the sampling rod groove is connected to the guide tube mounting groove.

[0011] A further improvement of this utility model lies in the arc-shaped structure of the outer wall of the sampling guide tube and the outer wall of the sampling cylinder.

[0012] A further improvement of this utility model is that: an adaptation groove is provided at the end of the push rod away from the sampling push rod, and the inner wall of the adaptation groove is slidably connected to the outer wall of the docking column.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This utility model provides a coal sampling device that utilizes the combined use of a discharge pipe, a feeding auger, a hydraulic rod, a sampling push rod, a pushing rod, and a sampling guide pipe to quickly transport and transfer the sample after sampling. This one-step process from sampling to sample transfer solves the problem of existing devices requiring multiple steps to transfer the sample after sampling, and ensures random sampling at every point in the carriage, significantly improving sampling efficiency.

[0015] This utility model provides a coal sampling device that utilizes the combined use of a feeding auger, a sampling guide tube, a guide tube mounting groove, and a discharge chute. After each sampling, the sample inside the sampling guide tube can be quickly transported and transferred by the feeding auger, avoiding residue. This facilitates sampling at other coal pile depths and locations, and prevents excessive sample mixing, which could lead to inaccurate subsequent testing. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides a coal sampling device, including a sampling cylinder 1 and a discharge pipe 2. A feeding auger 6 is rotatably connected inside the sampling cylinder 1, and a drive motor 3 is fixedly connected to the top of the feeding auger 6. A guide tube mounting groove 11 is formed on the outer wall of the sampling cylinder 1 near its bottom. A sampling guide tube 7 is rotatably connected to the inner wall of the guide tube mounting groove 11 via a shaft. A docking column 16 is fixedly connected to one side of the sampling guide tube 7, and a push rod 13 is movably connected to the outer wall of the docking column 16. A sampling push rod 5 is rotatably connected to the top of the push rod 13. The coordinated use of the feeding auger 6, the sampling guide tube 7, the guide tube mounting groove 11, and the discharge chute 12 allows the sampling guide tube 7 to quickly transport and transfer the sample inside the sampling guide tube 7 after each sampling, avoiding residue. This facilitates sampling at other coal pile depths and locations, and prevents excessive sample mixing, which could lead to inaccurate subsequent testing.

[0025] The bottom end of the feeding auger 6 is rotatably connected to the inner wall of the bottom end of the sampling cylinder 1.

[0026] The shaft on the sampling guide tube 7 is installed on the bottom side near the outer wall of the sampling cylinder 1.

[0027] The inner wall of the sampling cylinder 1 near the bottom is provided with a feeding groove 12 that connects with the bottom of the sampling guide tube 7. The top of the sampling cylinder 1 is provided with a sampling rod groove 4 for installing the sampling push rod 5. The top of the sampling push rod 5 is fixedly connected to a push plate 8, and the upper surface of the push plate 8 is fixedly connected to a hydraulic rod 9.

[0028] The inner wall of the sampling rod groove 4 is slidably connected to the outer wall of the sampling push rod 5. The top of the hydraulic rod 9 is fixedly connected to the mounting bracket 10, and the top of the inner wall of the mounting bracket 10 is fixedly connected to the top of the drive motor 3 by bolts.

[0029] The outer wall of the mounting bracket 10 is fixedly connected with reinforced support legs.

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the number of sampling guide tubes 7 is two sets, and the two sets of sampling guide tubes 7 are symmetrically distributed on both sides of the bottom end of the sampling cylinder 1. The sampling guide tube 7 and the feeding auger 6 are separated by the inner wall of the guide tube mounting groove 11, forming a cylindrical structure surrounding the feeding auger 6, ensuring that the feeding auger 6 can transport normally when the sampling guide tube 7 is being fed.

[0031] The inner wall of the sampling rod groove 4 is slidably connected to the outer wall of the sampling push rod 5, and the sampling rod groove 4 is connected to the guide tube mounting groove 11.

[0032] The outer wall of the sampling guide tube 7 has an arc-shaped structure that matches the outer wall of the sampling cylinder 1. The end of the push rod 13 away from the sampling push rod 5 is provided with a matching groove 17. The inner wall of the matching groove 17 is slidably connected to the outer wall of the docking column 16.

[0033] The working principle of this coal sampling device will be explained in detail below.

[0034] like Figure 1-5 As shown, the device is installed on the drive equipment. Then, the drive equipment drives the sampling cylinder 1 to be inserted into the coal pile to be sampled to a suitable depth. Then, the drive motor 3 and hydraulic rod 9 are started. When the drive motor 3 starts, it drives the feeding auger 6 to rotate. When the hydraulic rod 9 starts, it pushes the push plate 8 to move down. When the push plate 8 moves down, it pushes the sampling push rod 5 to move down the inner wall of the sampling rod slide 4. At the same time, the sampling push rod 5 pushes the push rod 13 to move down. After the push rod 13 moves down a certain distance, it pushes the docking column 16, so that the docking column 16 drives the sampling guide tube 7 to deflect outward on the inner wall of the guide tube mounting groove 11. As the inlet of the sampling guide tube 7 protrudes from the outer wall of the sampling cylinder 1, the coal particles in the coal pile will enter the discharge trough 12 under the action of pressure through the sampling guide tube 7. The coal particles entering the discharge trough 12 will move upward step by step under the drive of the feeding auger 6 until they are discharged through the discharge pipe 2, thus completing the sampling work.

[0035] After sampling is completed, the hydraulic rod 9 pulls the push plate 8 upward, and the push plate 8 drives the sampling guide tube 7 to reset through the sampling push rod 5 and the push rod 13. Then the drive equipment can raise the height of the sampling cylinder 1, thereby changing the depth of the sampling cylinder 1 inserted into the coal pile. At this time, the feeding auger 6 will transport the sample taken by the sampling guide tube 7 in the previous time. Then the sampling guide tube 7 is pushed outward to take samples, thus completing the sampling work of samples at different depths.

[0036] It should be noted that, in this document, the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The present invention has been described in detail above, but modifications or improvements can be made based on it, which will be apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
