[0021] Reference below Figures 1-12 A device 10 for quickly selecting and sampling coal from a coal pile according to an embodiment of the present invention is described.

[0022] like Figures 1-12 As shown, a coal pile rapid sampling device 10 according to an embodiment of the present invention includes: a vehicle body 1 , a first connecting member 2 , a rotating plate 3 and a sampler 4 .

[0023] Specifically, such as Figures 1-12 As shown, the first connecting member 2 is movably provided on the vehicle body 1 in the vertical direction; the rotating plate 3 is rotatably connected to the first connecting member 2, and the rotating axis of the rotating plate 3 is along the first direction (as shown in FIG. Figure 1 The sampler 4 is movably provided on the rotating plate 3, and the direction in which the sampler 4 moves is perpendicular to the first direction.

[0024] It is understood that the first connecting member 2 is movably mounted on the vehicle body 1 in the vertical direction, thereby enabling the position of the sampler 4 to be adjusted in the vertical direction, and the rotating plate 3 is rotatably connected to the first connecting member 2, thereby enabling the position of the sampler 4 to be adjusted in the rotation direction of the rotating plate 3, thereby allowing the sampler 4 to extend into the coal pile at a suitable angle. The sampler 4 is movably mounted on the rotating plate 3, wherein the extension direction of the rotating plate 3 is the same as the movement direction of the sampler 4, thereby enabling the position of the sampler 4 to be adjusted in the extension direction of the rotating plate 3.

[0025] Therefore, through the up and down movement of the first connecting member 2, the rotation of the rotating plate 3 and the movement of the sampler 4 relative to the rotating plate 3, the position adjustment method of the sampler 4 is increased, so that the coal pile coal rapid selection sampling device 10 can be suitable for different coal sampling environments (such as coal piles with different heights, inclinations, etc.). On the one hand, it can improve the efficiency of coal sampling, and on the other hand, it can accurately take coal samples at the required position, thereby improving the accuracy of subsequent detection.

[0026] According to the coal pile coal rapid selection sampling device 10 of the embodiment of the present invention, it is movably arranged on the vehicle body 1 along the up and down directions through the first connecting member 2; the rotating plate 3 is rotatably connected to the first connecting member 2, and the rotating axis of the rotating plate 3 extends along the first direction, and the up and down directions are perpendicular to the first direction; the sampler 4 is movably arranged on the rotating plate 3, and the moving direction of the sampler 4 is perpendicular to the first direction, which increases the position adjustment method of the sampler 4, so that the coal pile coal rapid selection sampling device 10 can be applied to different coal sampling environments. On the one hand, it can improve the efficiency of coal sampling, and on the other hand, it can accurately take coal samples at the required position, thereby improving the accuracy of subsequent detection.

[0027] In some embodiments of the present invention, Figure 1-Figure 3 and Figure 5-Figure 7 As shown, the coal pile coal rapid selection sampling device 10 also includes: a first driving mechanism 6, the first driving mechanism 6 is connected to the vehicle body 1, and is used to drive the first connecting member 2 to move in the up and down directions, thereby realizing the position adjustment of the first connecting member 2 in the up and down directions, thereby realizing the position adjustment of the sampler 4 in the up and down directions, so as to facilitate adaptation to coal piles of different heights.

[0028] Furthermore, if Figure 1-Figure 3 and Figure 5-Figure 7As shown, the first driving mechanism 6 includes: a mounting seat 61, a first driving member 62 and a first sliding rod 63. The mounting seat 61 is connected to the vehicle body 1. A first sliding space is provided in the mounting seat 61. The first sliding space extends in the up-down direction and passes through the upper end of the mounting seat 61. The first driving member 62 is provided on the mounting seat 61. The output shaft of the first driving member 62 is connected to the first connecting member 2 for driving the first connecting member 2 to move in the up-down direction. At least part of the first sliding rod 63 is movably provided in the first sliding space. The upper end of the first sliding rod 63 is connected to the first connecting member 2.

[0029] It can be understood that the first driving member 62 can be a cylinder, the first connecting member 2 is connected to the top of the first driving member 62, the output shaft of the first driving member 62 extends in the up and down directions, and the first driving member 62 drives the first connecting member 2 to move in the up and down directions, thereby driving at least part of the first sliding rod 63 to move in the up and down directions in the first sliding space.

[0030] At least part of the first sliding rod 63 is movably arranged in the first sliding space, which plays a guiding role. On the one hand, it improves the stability of the first connecting member 2 moving in the up and down directions. At the same time, it can prevent the first connecting member 2 from moving in a direction perpendicular to the up and down directions, thereby ensuring the installation stability of the first connecting member 2.

[0031] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 7 As shown, the first slide bar 63 has a plurality of slots 631 spaced apart in the up and down directions, and the mounting seat 61 has a block 612 that cooperates with the slots 631. The block 612 is movably arranged on the mounting seat 61 and is suitable for cooperating with one of the plurality of slots 631.

[0032] It can be understood that by cooperating with one of the card slots 631, the first slide bar 63 can be locked at one of the positions in the up and down directions, ensuring that the first slide bar 63 will not loosen and slide out of the mounting seat 61, thereby achieving the locking of the first connecting member 2 at one of the positions in the up and down directions.

[0033] Furthermore, if Figure 3 、 Figure 6 and Figure 7 As shown, along the direction from the slot opening of the slot 631 to the bottom wall of the slot 631 , the cross section of the slot 631 gradually decreases, and the cross section of the block 612 also gradually decreases, thereby playing a guiding role, allowing the block 612 to better enter the slot 631 and cooperate with the slot 631 .

[0034] Furthermore, if Figure 3 、 Figure 6 and Figure 7 As shown, the first driving mechanism 6 includes a fifth driving member 613, which is disposed on the mounting seat 61 and is used to drive the clamping block 612 to move so as to extend into the clamping slot 631 and engage with the clamping slot 631, or to drive the clamping block 612 to extend out of the clamping slot 631 and disengage from the clamping slot 631. The fifth driving member 613 may be a cylinder.

[0035] When the first slide bar 63 is rising, the rising height can be adjusted according to the height of the coal pile. After confirming the height, the fifth driving member 613 is started. The fifth driving member 613 drives the block 612 to slide, so that the block 612 is engaged with the slot 631, and the first slide bar 63 is locked in the current position to ensure that the first slide bar 63 will not slide down from the mounting seat 61. When the coal collection is completed, the fifth driving member 613 is started, the block 612 is no longer engaged with the slot 631, and the first driving member 62 is started to drive the first connecting member 2 to descend, thereby causing the sampler 4 to descend, making it easier to remove the sample.

[0036] In some embodiments of the present invention, Figure 1-Figure 3 and Figure 5-Figure 7 As shown, the mounting seat 61 includes two sub-seats 611 that are arranged opposite to each other and connected along the first direction, each sub-seat 611 has a first sliding space, each first sliding space extends in the up-down direction and passes through the upper end of the corresponding sub-seat 611, and there are two first slide rods 63 corresponding to the two sub-seats 611 one by one. The upper ends of the two first slide rods 63 are connected to the first connecting member 2, and the two sub-seats 611 have an opening 614 on one side facing each other, and the opening 614 extends in the up-down direction. The first driving mechanism 6 also includes: a connecting rod 64, which extends along the first direction, and the two ends of the connecting rod 64 in the length direction are respectively connected to the two first slide rods 63.

[0037] It is understood that the two first slide bars 63 simultaneously drive the first connector 2 to rise and fall, thereby making the lifting of the first connector 2 more stable. The two ends of the connecting rod 64 in the length direction are respectively connected to the two first slide bars 63, so that the two first slide bars 63 can rise and fall together, thereby making the lifting of the first connector 2 more stable. The provision of the opening 614 can avoid interference between the connecting rod 64 and the mounting base 61, so that the two ends of the connecting rod 64 in the length direction are respectively connected to the two first slide bars 63, and can also be raised and lowered with the two first slide bars 63.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a telescopic rod assembly 9 is connected between the mounting seat 61 and the vehicle body 1, and is used to drive the mounting seat 61 in the second direction (such as Figure 1 The first direction, the second direction and the up-down direction are perpendicular to each other.

[0039] It is understood that the telescopic rod assembly 9 can be driven by a pneumatic cylinder or a hydraulic cylinder. When coal collection is required, the telescopic rod assembly 9 is first activated to move the mounting base 61 to a certain distance from the vehicle body 1, thereby avoiding interference between the vehicle body 1 and the first driving mechanism 6. At the same time, the position of the sampler 4 in the second direction can also be adjusted by the arrangement of the telescopic rod assembly 9.

[0040] In some embodiments of the present invention, Figure 1 、 Figure 8 and Figure 9 As shown, the coal pile coal rapid selection sampling device 10 also includes: a second driving mechanism 7, the second driving mechanism 7 is provided on the first connecting member 2, and is used to drive the rotating plate 3 to rotate. The rotating plate 3 has a connecting block 31. The second driving mechanism 7 includes: a second driving member 71, a first gear 72, a second gear 73, two vertical plates 74 and a rotating rod 75.

[0041] The second driving member 71 is arranged on the first connecting member 2, and the output shaft of the second driving member 71 extends along the first direction; the first gear 72 rotates coaxially with the output shaft of the second driving member 71; the second gear 73 is connected to the rotating plate 3, and the second gear 73 is engaged with the first gear 72, wherein the second driving member 71 can be a motor; wherein the second gear 73 is a half gear, and is arranged on one side in the thickness direction of the rotating plate 3.

[0042] It can be understood that the upper end surface of the first connecting member 2 has two support plates 21 arranged opposite to each other along the first direction, and the output shaft of the second driving member 71 can be rotatably passed through the two support plates 21. The output shaft of the second driving member 71 drives the first gear 72 to rotate, and through the engagement of the first gear 72 and the second gear 73, the second gear 73 is driven to rotate, and is connected to the rotating plate 3 through the second gear 73, thereby driving the rotating plate 3 to rotate.

[0043] Furthermore, if Figure 1 、 Figure 8 and Figure 9 As shown, two vertical plates 74 are arranged opposite each other along the first direction and are provided on the first connecting member 2; a rotating rod 75 extends along the first direction, and the two ends of the rotating rod 75 in the longitudinal direction are respectively connected to the two vertical plates 74, and the connecting block 31 is rotatably sleeved outside the rotating rod 75. In this way, the rotating plate 3 is supported, so that the rotating plate 3 can rotate more stably.

[0044] In some embodiments of the present invention, Figure 1 、 Figure 4 、 Figure 10 and Figure 11As shown, the coal pile rapid sampling device 10 further includes a third drive mechanism 8 , which is disposed on the rotating plate 3 and is used to drive the sampler 4 to move. The rotating plate 3 has a chute 32 extending along the moving direction of the sampler 4 , with one end of the chute 32 being open in the longitudinal direction. The third drive mechanism 8 includes a fixed seat 81 , a third gear 82 , a sliding plate 83 , and a third drive member. The third drive member may be a motor.

[0045] The fixed seat 81 is connected to the rotating plate 3; the third gear 82 is rotatably provided on the fixed seat 81; at least a portion of the sliding plate 83 is movably provided in the slide groove 32 along the length direction of the slide groove 32, and the sliding plate 83 is detachably connected to the sampler 4. The sliding plate 83 has a rack 834 engaged with the third gear 82, and the rack 834 extends along the length direction of the slide groove 32; the output shaft of the third driving member is transmission-connected to the third gear 82 for driving the third gear 82 to rotate.

[0046] It is understood that the third driving member drives the third gear 82 to rotate, thereby driving the rack 834, so that the sliding plate 83 moves in the length direction of the slide 32, thereby adjusting the position of the sampler 4. The sliding plate 83 is detachably connected to the sampler 4, thereby facilitating the removal of samples from the sampler 4. The sampler 4 has a second connecting member 5 at one end, and the second connecting member 5 is connected to one end of the sliding plate 83 in the length direction. The sampler 4 is detachably connected to the second connecting member 5 (for example, by a threaded fastener), thereby achieving a detachable connection between the sliding plate 83 and the sampler 4.

[0047] When sampling is required, the third driving member drives the third gear 82 to start rotating, thereby driving the sliding plate 83 to slide on the slide groove 32. When the sliding plate 83 moves toward the outside of the slide groove 32, that is, extends outward, the overall length of the third driving member becomes longer, and the distance between the sampler 4 and the coal pile becomes shorter. The sampler 4 enters the coal pile to sample the coal. After the sampling is completed, the third driving member sliding plate 83 is started to move toward the inside of the slide groove 32 to facilitate the sampler 4 to be separated from the coal pile.

[0048] In some embodiments of the present invention, Figure 10 and Figure 11 As shown, the fixed seat 81 is arranged on the side of the sliding plate 83 away from the bottom wall of the sliding groove 32, the third gear 82 is arranged on the side of the fixed seat 81 facing the sliding plate 83, and the rack 834 is arranged on the side of the sliding plate 83 away from the bottom wall of the sliding groove 32.

[0049] In some embodiments of the present invention, Figure 10 and Figure 11As shown, the side of the sliding plate 83 facing away from the bottom wall of the chute 32 has a stop plate 831. The stop plate 831 is provided on the side of the fixing seat 81 facing away from the opening and is adapted to abut against the fixing seat 81. Thus, the stop plate 831 abuts against the fixing seat 81, thereby preventing the sliding plate 83 from being disengaged from the opening.

[0050] In some embodiments of the present invention, Figure 10 and Figure 11 As shown, the sliding plate 83 has a roller 832 on one side facing the bottom wall of the sliding groove 32 , thereby making the sliding plate 83 slide more smoothly on the sliding groove 32 .

[0051] In some embodiments of the present invention, Figure 10 and Figure 11 As shown, a slide rail 33 is provided on the side wall of the slide groove 32, and the slide rail 33 extends along the length direction of the slide groove 32. A second slide rod 833 is provided on the sliding plate 83 and extends along the length direction of the slide groove 32. At least a portion of the second slide rod 833 is movably arranged in the slide groove 32 along the length direction of the slide groove 32.

[0052] This plays a guiding role in the sliding of the sliding plate 83, on the one hand preventing the sliding plate 83 from being separated from the sliding groove 32, and on the other hand making the sliding of the sliding plate 83 smoother.

[0053] In some embodiments of the present invention, Figure 12 As shown, the sampler 4 includes: a housing 41, a spiral conveying blade shaft 42 and a fourth driving member 43, wherein the fourth driving member 43 can be a motor.

[0054] One end of the shell 41 in the length direction is open to form a material taking port 411, which is convenient for taking materials. The shell 41 also has a discharge port 412. The discharge port 412 and the material taking port 411 are respectively arranged at the two ends of the shell 41 in the length direction, so as to avoid the material entering from the material taking port 411 directly going out from the discharge port 412, so that the shell 41 can store a certain amount of samples. When it is necessary to take out the sample from the sampler 4, the material can be discharged from the discharge port 412.

[0055] The spiral conveying blade shaft 42 is rotatably disposed within the housing 41 and extends along the length of the housing 41. The rotation axis of the spiral conveying blade shaft 42 extends along the length of the housing 41. One end of the spiral conveying blade shaft 42 has a drill bit, which is inserted into the material discharging opening 411 and is at least partially located outside the housing 41. A fourth drive member 43 is disposed at the end of the housing 41 facing away from the material discharging opening 411.
