DETAILED DESCRIPTION

[0025] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0026] like Figures 1 to 5 As shown:

[0027] Embodiment 1: The utility model provides a sampler for coal quality testing, including a accommodating unit 1 for accommodating objects, including a accommodating barrel 11 for accommodating multiple sampling barrels 26, the accommodating barrel 11 is hollow, and accommodating grooves 12 for accommodating sliding rods 21 are respectively provided on the inner walls of the accommodating barrel 11, and a sealing plate 13 for closing the accommodating barrel 11 is fixedly connected to the top of the accommodating barrel 11.

[0028] As can be seen from the above, multiple sampling barrels 26 can be held by the accommodating barrel 11, and the inner wall of the accommodating barrel 11 can seal the opening on one side of the sampling barrel 26, thereby ensuring that the samples in the sampling barrel 26 will not fall.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the pushing unit 2 for pushing the object to move includes a slide rod 21 arranged in the receiving groove 12 to facilitate the movement of the slider 22, the slide rod 21 is fixedly connected to the receiving barrel 11, and the slide rod 21 is slidably connected with a slider 22 for pushing the connecting rod 24 to move.

[0030] Furthermore, an elastic member 23 for driving the connecting rod 24 to move is sleeved on the sliding rod 21 , one end of the elastic member 23 is fixedly connected to the bottom of the sliding block 22 , and the other end of the elastic member 23 is fixedly connected to the containing barrel 11 .

[0031] Furthermore, a connecting rod 24 for pushing the sampling barrel 26 to move is provided at the bottom of the slider 22, and the connecting rod 24 is fixedly connected to the slider 22. A limit block 25 is also provided on the connecting rod 24 for maintaining the connecting rod 24 to move linearly up and down. The limit block 25 is fixedly connected to the inner wall of the containing barrel 11, and the connecting rod 24 is slidably connected to the limit block 25.

[0032] Furthermore, a sampling barrel 26 for sampling and containing coal is fixedly connected to the bottom of the connecting rod 24 , and an opening is provided on one side of the sampling barrel 26 , and the opening of the sampling barrel 26 is tightly fitted to the inner wall of the containing barrel 11 .

[0033] Furthermore, a fixing block 27 is fixedly connected to the outer wall of the sampling barrel 26 for easy cooperation with the adjustment unit 3. The fixing block 27 is located at the bottom of the push plate 31. A semi-cone 28 is fixedly connected to the bottom of the sampling barrel 26 for easy insertion into the coal.

[0034] As can be seen from the above, when it is necessary to sample the coal, the adjusting unit 3 is pushed so that the adjusting unit 3 pushes the fixed block 27 to move, and the fixed block 27 drives the sampling barrel 26 to move, and the sampling barrel 26 drives the connecting rod 24 to move downward, and the connecting rod 24 is fixedly connected to the slider 22. Therefore, the slider 22 moves downward along the slide rod 21. At this time, the slider 22 squeezes the elastic member 23, and the elastic member 23 undergoes elastic deformation. As the fixed block 27 is continuously pushed, the fixed block 27 drives the sampling barrel 26 to slide out of the accommodating barrel 11. The sampling barrel 26 can be easily inserted into the interior of the coal through the semi-cone 28 set at the bottom of the sampling barrel 26, and the coal sample can enter the interior of the sampling barrel 26 from the opening opened in the sampling barrel 26, thereby completing the sampling work.

[0035] Furthermore, when the sampling is completed, the adjustment unit 3 can be stopped. At this time, the elastic member 23 is not subjected to force, and the elastic member 23 elastically resets. The elastic member 23 pushes the slider 22 to move upward along the slide rod 21. When the slider 22 moves, it drives the connecting rod 24 to move upward, and the connecting rod 24 is fixedly connected to the sampling barrel 26. Therefore, the connecting rod 24 drives the sampling barrel 26 to slide from the outside of the receiving barrel 11 into the inside of the receiving barrel 11. At this time, one side of the opening of the sampling barrel 26 is tightly fitted with the inner wall of the receiving barrel 11, thereby ensuring that the coal sample will not leak out.

[0036] Through the above operation, after sampling the coal, the device can automatically store the coal sample in the storage barrel 11 for storage, without the need for manual storage, thus saving manpower.

[0037] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the adjustment unit 3 includes a push plate 31 disposed inside the accommodating barrel 11 and used to push the fixed block 27 to move, a push rod 32 is disposed on the top of the push plate 31 and used to push the push plate 31 to move, and one end of the push rod 32 vertically penetrates the sealing plate 13 and is movably connected to the sealing plate 13.

[0038] Furthermore, a plurality of through slots 33 are vertically formed on the push plate 31 for the fixing blocks 27 to pass through, and the number of the through slots 33 is less than the number of the fixing blocks 27 .

[0039] Furthermore, a fixing plate 34 is fixedly connected to the top of the push rod 32 for facilitating the push rod 32 to move.

[0040] As can be seen from the above, when it is necessary to sample coal in multiple places, the fixed plate 34 can be rotated 90°, so that the fixed plate 34 drives the push rod 32 and the push plate 31 to rotate, thereby changing the position of the through groove 33 on the push plate 31, so that the push plate 31 can cooperate with different fixed blocks 27. By pushing the fixed plate 34, the push plate 31 can drive the sampling barrels 26 at different positions to extend out of the accommodating barrel 11, so that the sampling barrels 26 can sample the coal.

[0041] Through the above operation, the device only needs to rotate the push plate 31 in the adjustment unit 3 so that the push plate 31 cooperates with the fixed blocks 27 set on different sampling barrels 26, thereby pushing different sampling barrels 26 to sample the coal. As a result, when the device needs to sample coal in different places, multiple sampling operations can be performed without using multiple sampling devices for sampling, which greatly improves the sampling efficiency.

[0042] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
