[0002] In the process of coal mining, sampling the coal pile is a key task. The traditional manual sampling method usually involves digging and sampling at multiple points in the coal pile, and the digging needs to be done to a certain depth.

[0003] The current sampling operation is usually done manually, which means that workers need to constantly move and dig on the coal pile, which is very complicated and time-consuming. At the same time, when workers are operating on the coal pile, they may fall due to factors such as the slope of the coal pile, loose coal seams or unstable coal pile surfaces, which poses a great safety hazard.

[0004] In summary, the traditional manual sampling method is not only inefficient, but also has great safety risks. Therefore, in order to improve the safety and efficiency of sampling, it is urgent to introduce automated sampling equipment. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] A sampling device for mining, such as Figure 1-6 As shown, it includes a track assembly, a sliding assembly, a base plate 3, a linear drive member 4, a mounting plate 5, a motor 61, a dragon 62, a cylinder 7 and a collection assembly;

[0027] A sliding assembly is slidably connected to the track assembly; a base plate 3 is installed on the sliding assembly; two linear drive members 4 are installed on the base plate 3, and the linear drive members 4 are electric push rods; a mounting plate 5 is fixedly connected to the telescopic part of the linear drive member 4; a motor 61 is installed on the mounting plate 5; a dragon 62 is fixedly connected to the rotating part of the motor 61; the mounting plate 5 is fixedly connected to the cylinder 7 through two first connecting plates 71, and the dragon 62 is located on the inner side of the cylinder 7, and a through hole for passing the cylinder 7 is opened on the base plate 3; a collecting assembly for collecting coal pile samples at different positions is installed on the cylinder 7.

[0028] The dragon 62 also includes a rotating rod 63 , to which the bottom of the dragon 62 is fixedly connected.

[0029] The diameter of the rotating rod 63 is the same as the outer diameter of the cylinder 7 .

[0030] The collecting assembly includes a conveying shell 81, a collecting box 82, an electric door 83 and an elastic cover 84; the upper part of the cylinder 7 is connected to the conveying shell 81; the electric door 83 is installed at the lower part of the conveying shell 81; the collecting box 82 is detachably connected to the bottom plate 3; the elastic cover 84 is fixedly connected to the electric door 83 of the conveying shell 81, and the lower part of the elastic cover 84 is detachably connected to the collecting box 82.

[0031] The conveying shell 81 is arranged to be tilted downward to facilitate the dumping of coal blocks.

[0032] When the present invention is used, the present invention is as follows Figure 2 As shown, the device is placed on the coal pile, the track assembly contacts the coal pile, and then the sliding assembly is controlled to slide obliquely upward on the track assembly to the position where sampling is required, and then the linear drive member 4 is controlled to drive the mounting plate 5 to move toward the coal pile, thereby driving the motor 61, the dragon 62, and the cylinder 7 to move toward the coal pile. Figure 1 The status is shown as Figure 3 At the same time, the motor 61 is controlled to drive the dragon 62 to rotate and transport the coal into the cylinder 7, and then discharge it through the conveying shell 81. When the dragon 62 and the cylinder 7 dig to a sufficient depth, the electric door 83 is controlled to open, and then the coal falls downward from the electric door 83 of the conveying shell 81 and is transferred to the collection box 82. When the sampling is completed, the control of the present invention is reset to Figure 1 The state shown, and then the sliding assembly moves to the next sampling position and repeats the sampling.

[0033] It should be noted that the present invention can transfer coal mines above a fixed depth by means of the dragon 62, and shield the excavated holes by means of the cylinder 7 to prevent the holes from collapsing, thereby achieving complete sampling of coal pile samples at a fixed depth.

[0034] It should be noted that when the coal blocks fall downward from the electric door 83 of the conveying housing 81 and are transferred to the collecting box 82, the elastic cover 84 is used to shield and guide the coal blocks so that they are transferred smoothly.

[0035] From the above, it can be seen that the present invention realizes multi-point automated sampling of coal piles, which can effectively reduce the need for manual operation, reduce the safety risks of on-site operations, and improve the accuracy and consistency of sampling. It can also perform deep excavation at multiple predetermined sampling points and completely sample coal pile samples to a predetermined depth, avoiding various problems in manual operation, thereby improving the safety and efficiency of the entire sampling process.

[0036] Furthermore, since the coal pile is exposed to the outside, on rainy days, the coal pile will have certain caking or clustering phenomena, which will cause resistance when the dragon 62 and the cylinder 7 are excavated synchronously. Therefore, a rotating rod 63 is provided. When the dragon 62 rotates, the rotating rod 63 rotates synchronously. Because the diameter of the rotating rod 63 is the same as the outer diameter of the cylinder 7 and is arranged on the lower side of the cylinder 7, the caking or clustering coal blocks can be loosened in advance by the rotating rod 63, so that the dragon 62 and the cylinder 7 can dig downward smoothly and avoid the track assembly being bounced up by the reaction force.

[0037] Example 2

[0038] On the basis of Example 1, Figure 1-Figure 6 As shown, the track assembly is composed of a plurality of guide rails 11 and a first elastic connector 12 installed in an alternating manner. The guide rails 11 are made of lightweight materials or are hollow to reduce weight. The guide rails 11 are arranged in an N shape, and the first elastic connector 12 is made of rubber.

[0039] The sliding assembly is composed of a plurality of sliding blocks 21 and second elastic connecting members 22 which are installed alternately; an electric wheel 23 is installed on each sliding block 21, and the second elastic connecting member 22 is made of rubber.

[0040] A second connecting plate 31 is fixedly connected to the bottom plate 3 , and the second connecting plate 31 is rotatably connected to the slider 21 .

[0041] The guide rail 11 defines a sliding groove 111 which is inclined downward. The slider 21 has a protrusion 211 which slides in the sliding groove 111 .

[0042] It also includes a weight-bearing plate 9, which is detachably connected to the ground contact guide rail 11.

[0043] Furthermore, since the shape of the coal pile is not a complete cone, there is a problem of fitting the track assembly with the coal pile. Therefore, the present invention provides a guide rail 11 and a first elastic connector 12. The presence of the first elastic connector 12 allows adjacent guide rails 11 to rotate relative to each other, thereby allowing several guide rails 11 to fit more closely with the coal pile, thereby ensuring the excavation depth and the accuracy of the sampling data.

[0044] At the same time, in order to enable the sliding assembly to slide smoothly on several guide rails 11, a plurality of sliders 21 connected by a second elastic connector 22 are configured to adapt to the guide rails 11. When adjacent guide rails 11 rotate relative to each other, the second elastic connector 22 can also allow adjacent sliders 21 to rotate relative to each other to adapt to achieve normal sliding.

[0045] At the same time, the bottom plate 3 is rotatably connected to the adjacent slider 21 via the second connecting plate 31 , so that when the adjacent guide rails 11 rotate relatively, the bottom plate 3 and the slider 21 can rotate relatively to adapt.

[0046] It should be noted that when the present invention is sampled, Figure 1 As shown, the bottom plate 3 is in complete contact with one of the guide rails 11 , and the dragon 62 and the cylinder 7 can dig into the coal pile through the n-shaped guide rail 11 .

[0047] Furthermore, since the coal block may get stuck in the sliding groove 111 , the sliding groove 111 is opened tilted downward, so that when the protrusion 211 slides over, the coal block can be cleaned out, thereby preventing the coal block from getting stuck in the sliding groove 111 .

[0048] Furthermore, by providing a load-bearing plate 9 on the guide rail 11 in contact with the ground and placing heavy objects on the load-bearing plate 9, it is possible to prevent the entire track assembly from tilting left and right.

[0049] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
