Technical Field

[0001] The invention belongs to the technical field of coal sampling, in particular to an intelligent coal pile sampling machine. Background Art

[0002] At present, the coal entering the factory and the coal entering the furnace need to be sampled and processed before use. The corresponding coal samples are collected for component analysis to determine the quality of the coal.

[0003] In the prior art, sampling operations on coal piles mostly involve inserting a sampling mechanism into the coal pile. At this time, a certain coal sample enters the sampling mechanism, and then the sampling mechanism is pulled out from the coal pile, thereby taking out the corresponding coal sample. However, after the sampling mechanism is pulled out from the coal pile, corresponding coal pile holes will be left on the coal pile due to the samples being taken out. Since the coal pile holes can no longer provide effective support for the coal pile, there is a greater risk of collapse of the coal pile, thereby causing safety problems. Summary of the invention

Specific implementation manner

[0031] The technical solution of the present invention will be further described in detail below in conjunction with the specific implementation manner.

[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a coal pile intelligent sampling machine, including a bottom plate 10, a lifting assembly 20, a sampling assembly 30, a driving assembly 40 and a coal fetching assembly 50. A support 101 is fixedly arranged on the upper part of the bottom plate 10. The sampling assembly 30 is arranged on the side wall of the support 101. The lifting assembly 20 is installed inside the support 101 and is used to drive the sampling assembly 30 to move up and down to adjust the height of the sampling assembly 30. The driving assembly 40 is arranged outside the sampling assembly 30 and is used to drive the sampling assembly 30 to move horizontally to sample the coal pile. The coal fetching assembly 50 is arranged above the sampling assembly 30 and is used to collect the coal at the top layer of the coal pile and convey the collected coal to the coal pile hole through the sampling assembly 30 to fill the coal pile hole.

[0034] When sampling treatment is required for a coal pile, the bottom plate 10 can be placed in front of the coal pile. Then, the lifting assembly 20 drives the sampling assembly 30 to move up and down, so that the sampling assembly 30 moves to a predetermined height. Subsequently, the driving assembly 40 drives the sampling assembly 30 to move horizontally. When the sampling assembly 30 moves horizontally, it inserts into the interior of the coal pile from the side of the coal pile to sample the coal in the coal pile. After sampling, a coal pile hole will be left on the side of the coal pile due to the previous coal sampling. At this time, the coal taking assembly 50 collects the coal at the top layer of the coal pile and conveys the collected coal into the interior of the coal pile hole through the sampling assembly 30, thereby filling the coal pile hole to a certain extent and reducing the probability of the coal pile collapsing.

[0035] Please refer to Figure 1 In one embodiment, the sampling assembly 30 includes a sampling cylinder 301, a screw conveyor 302, and a second motor 305. The screw conveyor 302 is disposed inside the sampling cylinder 301 and is distributed along the length direction of the sampling cylinder 301. The second motor 305 is fixedly installed outside one end of the sampling cylinder 301 and is used to drive the screw conveyor 302 to rotate. A sample delivery pipe 303 is provided at the bottom of the sampling cylinder 301. A sample storage box (not shown in the figure) is provided on the upper part of the bottom plate 10. The lower end of the sample delivery pipe 303 is connected to the sample storage box.

[0036] The lifting assembly 20 drives the sampling cylinder 301 and the screw conveyor 302 to move up and down to adjust the height of the sampling cylinder 301 and the screw conveyor 302. When the sampling cylinder 301 moves to a predetermined height, the driving assembly 40 drives the sampling cylinder 301 and the screw conveyor 302 to move horizontally as a whole. When the sampling cylinder 301 moves horizontally, the end away from the second motor 305 acts on the side of the coal pile and then inserts into the interior of the coal pile. At this time, the second motor 305 drives the screw conveyor 302 to rotate. When the screw conveyor 302 rotates, it brings the coal in the coal pile into the interior of the sampling cylinder 301 and drives the coal to move along the interior of the sampling cylinder 301. When the coal moves to the upper end position of the sample delivery pipe 303, it can enter the interior of the sample delivery pipe 303 and is then conveyed to the interior of the sample storage box by the sample delivery pipe 303, thus completing the sampling of the coal.

[0037] Please refer to Figure 1 and Figure 2, in one embodiment, the lifting assembly 20 includes a first motor 201, a first guide rod 202, a lifting plate 203 and a first lead screw 204. The first lead screw 204 and the first guide rod 202 are vertically arranged inside the bracket 101. The first lead screw 204 and the first guide rod 202 are parallel to each other. The lifting plate 203 is sleeved outside the first lead screw 204 and the first guide rod 202. The lifting plate 203 is in threaded cooperation with the first lead screw 204 and is movably cooperated with the first guide rod 202. The first motor 201 is fixedly installed on the upper part of the bottom plate 10 and is used to drive the first lead screw 204 to rotate. The sampling cylinder 301 is installed on one side of the lifting plate 203.

[0038] The first motor 201 drives the first lead screw 204 to rotate. By using the threaded cooperation between the first lead screw 204 and the lifting plate 203 and the movable cooperation between the lifting plate 203 and the first guide rod 202, when the first lead screw 204 rotates, it can drive the lifting plate 203 to move up and down, and then drive the sampling cylinder 301 to move up and down, realizing the adjustment of the height of the sampling cylinder 301, and then sampling the coal at different height positions on the side of the coal pile.

[0039] Please refer to Figure 1 and Figure 2 , in one embodiment, the driving assembly 40 includes a third motor 401, a second guide rod 402, a slider 403 and a second lead screw 404. The third motor 401 is fixedly arranged on the side wall of the lifting plate 203. There are two groups of sliders 403, and the two groups of sliders 403 are respectively fixedly arranged on the outer wall of the sampling cylinder 301. One end of the second guide rod 402 is fixedly connected to the lifting plate 203, and the other end passes through one group of the sliders 403 and is movably cooperated with this group of sliders 403. One end of the second lead screw 404 is connected to the output end of the third motor 401, and the other end passes through the other group of sliders 403 and is in threaded cooperation with this group of sliders 403.

[0040] After the height of the sampling cylinder 301 is adjusted, the third motor 401 drives the second lead screw 404 to rotate. By using the threaded cooperation between the second lead screw 404 and the corresponding slider 403 and the movable cooperation between the second guide rod 402 and the corresponding slider 403, the second lead screw 404 can drive the sampling cylinder 301, the screw conveyor 302 and the second motor 305 to move horizontally as a whole, so that one end of the sampling cylinder 301 far from the second motor 305 is inserted into the coal pile. At the same time, the second motor 305 drives the screw conveyor 302 to rotate, and then conveys the coal in the coal pile into the sampling cylinder 301, and at the same time drives the coal to enter the sample storage box through the sample conveying pipeline 303, thus completing the sampling of the coal.

[0041] Please refer to Figure 1 In one embodiment, a vertically distributed guide rail 102 is fixedly arranged on the side wall of the bracket 101. A top coal conveying pipeline 304 is arranged at the upper end of the sampling cylinder 301. The coal taking assembly 50 includes a coal pushing assembly 501, a coal conveying box body 502, a first hydraulic cylinder 504, a support plate 505 and a second hydraulic cylinder 506. One end of the support plate 505 is slidably matched with the guide rail 102, and the other end is connected to the coal pushing assembly 501. A support rod 503 is fixedly arranged at the bottom of the support plate 505. The coal conveying box body 502 is hinged at the lower end of the support rod 503. The lower end of the coal conveying box body 502 is connected to the top coal conveying pipeline 304. The first hydraulic cylinder 504 is installed at the bottom of the support plate 505 and is used to drive the coal conveying box body 502 to rotate relative to the support rod 503. The second hydraulic cylinder 506 is installed at the top of the bracket 101 and is used to drive the support plate 505 to move up and down.

[0042] When the sampling cylinder 301 is inserted into the coal pile to a certain depth and the coal sampling is completed, the third motor 401 is turned off. At this time, the sampling cylinder 301 remains inserted into the coal pile, and then the coal pile hole is expanded and supported. Subsequently, the second hydraulic cylinder 506 drives the support plate 505 to move up and down, thereby driving the coal pushing assembly 501 and the coal conveying box body 502 to move up and down. When the coal conveying box body 502 moves to a certain height, the first hydraulic cylinder 504 is used to drive the coal conveying box body 502 to rotate relative to the support rod 503, so that the upper end of the coal conveying box body 502 contacts the top of the coal pile. Then, the coal pushing assembly 501 is used to push the coal on the top layer of the coal pile, so that the top layer coal enters the interior of the coal conveying box body 502, and then is conveyed to the interior of the top coal conveying pipeline 304 by the coal conveying box body 502, and finally is conveyed to the interior of the sampling cylinder 301 through the top coal conveying pipeline 304. During this process, the second motor 305 can be used to drive the spiral conveyor 302 to rotate in the reverse direction, so as to convey the coal from the top layer of the coal pile entering the sampling cylinder 301 along the interior of the sampling cylinder 301. Finally, the top layer coal can enter the coal pile hole through the end of the sampling cylinder 301, so as to fill the coal pile hole to a certain extent and reduce the probability of coal pile collapse; during the process of the spiral conveyor 302 rotating in the reverse direction to convey the top layer coal into the coal pile hole, the third motor 401 can be used to drive the second lead screw 404 to rotate in the reverse direction, thereby driving the sampling cylinder 301 and the spiral conveyor 302 to move outward from the coal pile hole, so that the spiral conveyor 302 can convey the top supported coal to different depth positions of the coal pile hole, thus realizing the uniform filling of the interior of the coal pile hole.

[0043] In one embodiment, the top coal conveying pipeline 304 and the sample conveying pipeline 303 are both flexible pipelines, so that when the sampling cylinder 301 and the coal conveying box body 502 move, the top coal conveying pipeline 304 and the sample conveying pipeline 303 can be bent and deformed appropriately.

[0044] Please refer to Figure 4 , in one embodiment, the coal pushing component 501 includes a fourth motor 5011, a runner 5012, a pushing piece 5013 and a support 5014. The support 5014 is fixedly installed at the bottom of the support plate 505. The fourth motor 5011 is fixedly arranged on the side wall of the support 5014. The runner 5012 is arranged at the output end of the fourth motor 5011. There are several groups of the pushing pieces 5013, and several of the pushing pieces 5013 are fixedly arranged on the circumferential side wall of the runner 5012.

[0045] When the upper end of the coal conveying box body 502 contacts the top of the coal pile, the runner 5012 and several pushing pieces 5013 are located on the side of the coal conveying box body 502 and act on the top of the coal pile synchronously. At this time, the fourth motor 5011 can be driven to drive the runner 5012 to rotate, and then drive several pushing pieces 5013 to rotate. When the pushing pieces 5013 rotate, the coal on the top layer of the coal pile is pushed into the coal conveying box body 502. The top-layer coal is then conveyed from the inside of the coal conveying box body 502 to the inside of the top coal conveying pipeline 304, and finally conveyed to the inside of the sampling cylinder 301 through the top coal conveying pipeline 304, and then conveyed to the coal pile hole by the reversely rotating sample conveying screw 302, so as to realize the filling of the coal pile hole.

[0046] Please refer to Figure 3 , in one embodiment, a plurality of casters 103 are installed at the bottom of the bottom plate 10.

[0047] Through the setting of the casters 103, the flexible walking of the whole sampling machine can be facilitated, and thus the flexible sampling of the coal pile can be realized.

[0048] In the embodiment of the present invention, when sampling treatment needs to be carried out on a coal pile, the bottom plate 10 can be placed in front of the coal pile, and then the lifting component 20 is used to drive the sampling component 30 to move up and down, so that the sampling component 30 moves to a predetermined height. Subsequently, the driving component 40 is used to drive the sampling component 30 to move horizontally. When the sampling component 30 moves horizontally, it inserts into the coal pile from the side of the coal pile to sample the coal in the coal pile. After sampling, a coal pile hole will be left on the side of the coal pile due to the previous coal sampling. At this time, the coal taking component 50 is used to collect the coal on the top layer of the coal pile and convey the collected coal to the inside of the coal pile hole through the sampling component 30, so as to fill the coal pile hole to a certain extent, thereby reducing the probability of the coal pile collapsing. Compared with the prior art, during the coal pile sampling process, the probability of the coal pile collapsing can be effectively reduced, and thus the sampling safety can be improved.

[0049] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
