Technical Field
[0001] The utility model relates to the field of coal sample collection, and particularly relates to a coal sample collection device for coal geochemical research. Background Technique
[0002] In order to comprehensively utilize coal resources and solve the environmental problems generated during the utilization process, it is necessary to carry out coal geochemical research. When carrying out coal geochemical research, it is necessary to collect coal samples for analysis and testing. When sampling underground, traditional manual sampling often uses a shovel for sampling, which is inconvenient to operate, the sampling is irregular, and it is difficult to collect when encountering thermally metamorphosed coal that has become hard due to magmatic intrusion. Content of the Utility Model
[0003] In order to solve the technical problems that traditional manual sampling often uses a shovel for sampling, which is inconvenient to operate, the sampling is irregular, and it is difficult to collect when encountering thermally metamorphosed coal that has become hard due to magmatic intrusion, the utility model provides a coal sample collection device for coal geochemical research.
[0004] The utility model is realized by adopting the following technical solutions: A coal sample collection device for coal geochemical research includes a device main body. A driving motor is arranged at the top end of the device main body. A driving rod is connected to the top end of the driving motor. A grip sleeve and a movable sleeve are sleeved on the outer surface of the driving rod. A receiving block is fixedly connected to the outside of the movable sleeve. A rotation axis center is arranged on the surface of the receiving block. A rotation gear block is inserted through the outside of the rotation axis center. The rotation gear block is inserted inside the receiving block. The rotation axis center penetrates through the receiving block and the rotation gear block. The rotation gear block rotates around the receiving block with the rotation axis center as the base point.
[0005] A telescopic support rod is connected to the outside of the rotation gear block. A support foot is fixedly connected to the top end of the telescopic support rod. The support foot supports on the coal wall.
[0006] By pulling the telescopic support rod, the top end of the telescopic support rod rotates around the receiving block through the rotation axis center, so that the telescopic support rod adjusts its position, driving the support foot to adjust to a suitable position. At the same time, by pulling and adjusting the telescopic support rod, the telescopic support rod can adjust its extended length, facilitating the fixing of the support foot on the surface of the coal wall, thereby performing better collection operations.
[0007] As a further improvement of the above solution, at least two groups of telescopic support rods are provided. The two groups of telescopic support rods support on both sides of the cutting sampling head.
[0008] As a further improvement of the above solution, the telescopic support rod is composed of two groups of rod bodies, and the two groups of rod bodies can be telescoped; the front end of the support foot is in an inverted triangular shape, which is convenient for fixing on the surface of the coal wall.
[0009] As a further improvement of the above solution, a rotating rod is connected to the top end of the driving rod. The driving rod and the rotating rod are connected together. When the driving rod rotates, it drives the rotating rod to rotate synchronously. One end of the receiving block is fixedly connected to a fixed rod, and the other end of the fixed rod is connected to a limiting sleeve. The rotating rod passes through the limiting sleeve, and the top end of the rotating rod is connected to a cutting sampling head. The cutting sampling head is cylindrical, the inside of the cutting sampling head is hollow, and the top end of the cutting sampling head is circumferentially sharp.
[0010] As a further improvement of the above solution, when coal sample collection is required, the staff holds the grip sleeve with their hand, presses the support foot against the surface of the coal wall, so that the cutting sampling head aligns with the coal sample. Through the operation of the driving motor, the driving motor immediately drives the driving rod to rotate synchronously. The driving rod thus rotates inside the grip sleeve, and the driving rod drives the connected rotating rod to rotate synchronously. The rotating rod drives the cutting sampling head connected to its top end to rotate synchronously. The cutting sampling head thus cuts and samples the surface of the coal sample. After cutting, the coal sample is collected in the cavity inside the cutting sampling head, and then the staff takes out the coal sample for collection.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. By pulling the telescopic support rod of the present utility model, the top end of the telescopic support rod rotates around the receiving block through the rotation axis, so that the telescopic support rod adjusts its position, driving the support foot to adjust to a suitable position. At the same time, by pulling and adjusting the telescopic support rod, the telescopic support rod can adjust the extended length, facilitating the fixation of the support foot on the surface of the coal wall, thereby performing better collection operations.
[0013] 2. Through the operation of the driving motor of the present utility model, the driving motor drives the driving rod to rotate synchronously. The driving rod thus rotates inside the grip sleeve, and the driving rod drives the connected rotating rod to rotate synchronously. The rotating rod drives the cutting sampling head connected to its top end to rotate synchronously. The cutting sampling head thus cuts and samples the surface of the coal sample. After cutting, the coal sample is collected in the cavity inside the cutting sampling head, and then the staff takes out the coal sample for collection. Description of the Drawings

The rotating gear block 8 is inserted inside the bearing block 6. The rotation axis 7 penetrates through the bearing block 6 and the rotating gear block 8. The rotating gear block 8 rotates around the bearing block 6 with the rotation axis 7 as the base point.

[0022] The staff adjusts the position by pulling the telescopic support rod 9. The top of the telescopic support rod 9 rotates around the bearing block 6 through the rotation axis 7, and thus the telescopic support rod 9 adjusts its position, driving the support foot 10 to adjust to a suitable position. At the same time, by pulling and adjusting the telescopic support rod 9, the telescopic support rod 9 can adjust the extended length, which is convenient for the support foot 10 to be fixed on the surface of the coal wall, so as to perform better collection operations.
[0023] The top end of the driving rod 3 is connected to a rotating rod 31. The driving rod 3 and the rotating rod 31 are connected together.

The cutting sampling head 13 is cylindrical, the inside of the cutting sampling head 13 is hollow, and the top end of the cutting sampling head 13 is circumferentially sharp.

Through the operation of the driving motor 2, the driving motor 2 immediately drives the driving rod 3 to rotate synchronously. The driving rod 3 thus rotates inside the grip sleeve 4. The driving rod 3 drives the rotating rod 31 connected thereto to rotate synchronously. The rotating rod 31 drives the cutting sampling head 13 connected to its top end to rotate synchronously. The cutting sampling head 13 thus cuts and samples the surface of the coal sample. After cutting, the coal sample is collected inside the cavity of the cutting sampling head 13. Subsequently, the staff takes out the coal sample for collection.
