Description

Technical Field

[0001] This invention belongs to the field of sampling device technology, specifically relating to an automatic coal quality sampling vehicle. Background Technology

[0002] As my country's primary energy source and industrial raw material, coal quality testing is crucial for trade, pricing, combustion efficiency, and environmental emission control. The accuracy of coal quality testing depends first and foremost on the representativeness of the collected samples. However, as a bulk commodity, coal exhibits significant particle size segregation (the natural separation of large and small coal particles due to differences in rolling properties) and uneven moisture distribution during storage, posing a significant challenge to obtaining representative samples.

[0003] Existing coal sampling equipment mostly employs a spiral drilling method, inserting a sampling cylinder into the coal pile to collect a complete columnar sample, and then pulling the sampling cylinder out of the coal pile to release the entire coal sample. This method has the following technical problems: 1. A columnar sample contains multiple coal samples at different depths. During the unloading process, coal samples at different depths will mix, resulting in insufficient representativeness of the coal strata.

[0004] 2. The coal content in a single column sample is fixed, making it impossible to flexibly adjust the coal sample volume to meet different analytical needs.

[0005] 3. Existing coal sampling equipment only completes the sampling action, while subsequent sample preparation steps such as crushing, reducing and collecting still need to be done manually elsewhere, which is inefficient and increases the risk of sample contamination and loss during transportation.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] like Figures 1 to 8 As shown, the automatic coal sampling vehicle provided by the present invention includes: a mobile vehicle body 1 and a drilling assembly, an unloading assembly, a conveyor belt 2, a rotary crusher 3, a reducing assembly, a coal collection assembly, and a residual coal scattering assembly installed on the mobile vehicle body 1. The drilling assembly is used to sample coal. The unloading assembly is used to unload the coal sampled by the drilling assembly to the conveyor belt 2. The conveyor belt 2 is used to transport the coal into the rotary crusher 3. The rotary crusher 3 is used to crush the coal. The reducing assembly is located below the discharge port of the rotary crusher 3 for reducing the coal. The coal collection assembly is located below the third discharge port 50 of the reducing assembly for collecting the coal. The residual coal scattering assembly is connected to the reducing assembly and the coal collection assembly for scattering excess coal. The drilling assembly includes a lifting frame 4 and a sampling cylinder 5. The lifting frame 4 is fixedly installed on the mobile vehicle body 1. The lifting frame 4 is provided with a lifting plate 6 that moves in the vertical direction. The sampling cylinder 5 is fixedly connected to the lower surface of the lifting plate 6. The upper part of the sampling cylinder 5 is provided with a first discharge port 7 and a second discharge port 8. Both the first discharge port 7 and the second discharge port 8 are equipped with electrically controlled gates 9. The unloading assembly includes: a first unloading cylinder 10, a second unloading cylinder 11, and a control plate 12. The first unloading cylinder 10 is fixedly installed at the upper end of the feed inlet of the conveyor belt 2 and has a sliding groove on its inner wall. The upper end of the second unloading cylinder 11 is located below the second discharge port 8 of the sampling cylinder 5 and is slidably fitted inside the first unloading cylinder 10. A sliding block 13 is fixedly connected to the lower part of the second unloading cylinder 11 and is slidably connected in the sliding groove. A spring 14 is fixedly connected between the sliding block 13 and the bottom surface of the sliding groove. A control block 15 is fixedly fitted on the upper part of the second unloading cylinder 11. The control plate 12 is fixedly connected to the outer wall of the sampling cylinder 5 and is located above the control block 15.

[0020] When sampling coal, the mobile vehicle 1 is first moved above the sampling point. The sampling cylinder 5 is then moved downward by the lifting plate 6, allowing it to be inserted into the coal pile. During insertion, the electrically controlled gate 9 of the first discharge port 7 is opened, and the electrically controlled gate 9 of the second discharge port 8 is closed. At this time, the coal inside the sampling cylinder 5 is discharged from the first discharge port 7 and directly thrown onto the surface of the coal pile. After the sampling cylinder 5 reaches the target sampling depth, the first discharge port 7 continues to discharge for a period of time, thereby draining the coal sample from the non-target sampling depth inside the sampling cylinder 5. Then, the electrically controlled gate 9 of the first discharge port 7 is closed, and the electrically controlled gate 9 of the second discharge port 8 is opened, allowing the coal to be discharged from the second discharge port 8. The coal falls into the second unloading cylinder 11 and then onto the conveyor belt 2, where it is transported to the rotary crusher 3 for crushing and then into the reducing component for reducing. The retained coal falls into the coal collection component for collection, and the rejected coal is re-thrown into the coal pile through the residual coal throwing component.

[0021] As the sampling cylinder 5 descends, the control plate 12 applies downward pressure to the control block 15, causing the second unloading cylinder 11 to slide downward within the first unloading cylinder 10. This ensures that the upper end of the second unloading cylinder 11 remains at a certain distance below the second discharge port 8, guaranteeing that the coal discharged from the second discharge port 8 falls into the second unloading cylinder 11, thus preventing coal from splashing.

[0022] It achieves fully automated and seamless integration of the entire process from drilling and sampling, unloading, conveying, crushing, and reducing to the final sample collection and residual coal treatment, without the need for manual intervention. This significantly improves sampling efficiency and reduces labor intensity. Through the setting of the residual coal throwing component, excess coal can be automatically and quickly conveyed and thrown back to the coal yard, avoiding on-site accumulation and ensuring a clean working environment.

[0023] Furthermore, the sampling cylinder 5 includes an outer cylinder 16, a drive motor 17, and a spiral rod 18. The outer cylinder 16 is fixedly connected to the lower surface of the lifting plate 6. The drive motor 17 is fixedly installed inside the outer cylinder 16. The spiral rod 18 is fixedly installed on the output end of the drive motor 17, and the lower part of the spiral rod 18 extends out from the lower part of the outer cylinder 16.

[0024] By extending the lower part of the auger 18 from the lower part of the outer cylinder 16, after the auger 18 collects and transports coal at a certain depth, the surrounding coal will collapse onto the auger 18, facilitating continuous collection of coal by the auger 18 and improving the coal collection efficiency. The outer cylinder 16 ensures that the coal will not come into contact with coal at other depths during the lifting process, thus ensuring that the coal sample has sufficient stratigraphic representativeness.

[0025] Furthermore, the reducing assembly includes: a collection funnel 19, a reducing box 20, and a discharge cylinder 21. The reducing box 20 is fixedly installed on the mobile vehicle body 1. The collection funnel 19 is fixedly installed on the upper end of the reducing box 20. The discharge cylinder 21 is fixedly installed on the lower end of the reducing box 20, and the lower end of the discharge cylinder 21 is provided with a third discharge port 50 communicating with the coal collection assembly. The side wall of the discharge cylinder 21 is provided with a fourth discharge port 51 communicating with the residual coal scattering assembly.

[0026] After the coal is reduced in the reducing box 20, the retained coal flows out from the third discharge port 50 and falls into the coal collection component for collection, while the rejected coal flows out from the fourth discharge port 51 and is re-spread into the coal pile through the residual coal spreading component. By setting two discharge ports, the retained coal and rejected coal can be discharged at the same time, which improves the reducing efficiency.

[0027] Furthermore, the residual coal scattering assembly includes: a protective box 22, a second conveyor belt 23, and a conveying pipe 24. The protective box 22 is fixedly installed on the mobile vehicle body 1 and communicates with the coal collection assembly. The second conveyor belt 23 is fixedly installed inside the protective box 22. The conveying pipe 24 is fixedly connected to the top surface of the protective box 22 and communicates with the fourth discharge port 51 of the shrinking assembly.

[0028] By setting the conveying pipe 24, it is ensured that the coal flowing out from the fourth discharge port 51 of the splitting component can accurately fall onto the second conveyor belt 23, thus avoiding the splashing of coal flow.

[0029] Furthermore, the coal collection assembly includes: a collection box 25, a spring rod 26, a second spring 27, a first support plate 28, and a second support plate 29. The collection box 25 is fixedly installed on the mobile vehicle body 1. A discharge port is provided on the side wall of the collection box 25. The spring rod 26 is fixedly installed on the inner bottom surface of the collection box 25. The first support plate 28 is fixedly installed on the upper end of the piston rod of the spring rod 26. The second support plate 29 is installed above the first support plate 28 through the second spring 27. The upper surface of the second support plate 29 is inclined and is provided with an installation groove 30 for installing a sample box 31. Two sets of first locking components are provided in the installation groove 30 for locking the sample box 31.

[0030] When collecting coal, the sample box 31 is installed in the mounting groove 30. Through the inclined design of the upper surface of the second support plate 29 and the setting of the discharge port on the side wall of the collection box 25, the coal falling outside the sample box 31 can automatically roll down the inclined surface into the residual coal scattering component for scattering, without the need for manual cleaning, thus reducing the difficulty of use.

[0031] Furthermore, the second support plate 29 is provided with a locking cavity 32. The first locking assembly includes: a hinge seat 33, a sliding seat 34, a connecting rod 35, and a locking block 36. The hinge seat 33 is fixedly connected to the upper surface of the first support plate 28. The sliding seat 34 is slidably connected to the lower surface of the second support plate 29 in the left-right direction, and a control rod 52 extending into the locking cavity 32 is fixedly connected to the upper surface of the sliding seat 34. The locking block 36 is slidably installed in the locking cavity 32 and a spring 37 is fixedly connected to the inner wall of the locking cavity 32. The two ends of the connecting rod 35 are respectively hinged to the hinge seat 33 and the sliding seat 34. The lower part of the sample box 31 is provided with a groove that cooperates with the locking block 36.

[0032] After the empty sample box 31 is installed in the mounting slot 30, the locking block 36 will be inserted into the groove at the bottom of the sample box 31 to lock the sample box 31 and prevent it from tipping over under the impact of the coal. As the amount of coal in the sample box 31 increases, the spring 27 is compressed, causing the sliding seats 34 on both sides to move away from each other. Then, the control rod 52 drives the locking block 36 to slide into the locking cavity 32, thereby gradually unlocking the sample box 31 and making it easier for the staff to take it out.

[0033] Furthermore, the coal collection assembly also includes a coal flow regulating assembly, which includes: two sets of second locking assemblies symmetrically arranged inside the first support plate 28, a first lifting block 38, a second lifting block 39, a second connecting rod 40, a mounting frame 41, and an adjusting plate 42. The second locking assemblies are used to lock the upper and lower positions of the first support plate 28. The first lifting block 38 is fixedly connected to the first support plate 28 and slidably connected to the inner wall of the collection box 25 in the upper and lower direction. The second lifting block 39 is slidably connected to the inner wall of the collection box 25 in the upper and lower direction and is fixedly connected to the first lifting block 38 by a rigid rod. The mounting frame 41 is fixedly connected to the third discharge port 50 of the shrinking assembly. The adjusting plate 42 is rotatably mounted on the mounting frame 41. The two ends of the second connecting rod 40 are respectively hinged to the lower part of the adjusting plate 42 and the second lifting block 39.

[0034] Furthermore, the left and right inner walls of the collection box 25 are provided with locking grooves. The first support plate 28 has two control cavities 43 corresponding to the second locking assembly. The second locking assembly includes: a second hinge seat 44, a second sliding seat 45, a third connecting rod 48, a center block 46, two second locking blocks 47, and two fourth connecting rods 53. The second hinge seat 44 is fixedly connected to the lower surface of the second support plate 29. The second sliding seat 45 is slidably connected to the upper surface of the first support plate 28 in the front-back direction and is fixedly connected to the center block 46. The two ends of the third connecting rod 48 are respectively hinged to the second hinge seat 44 and the second sliding seat 45. The center block 46 is slidably connected in the front-back direction in the control cavity 43 and is fixedly connected to the inner wall of the control cavity 43 with a fourth spring 49. The two second locking blocks 47 are respectively slidably connected in the left-right direction to the left and right ends of the control cavity 43. The center block 46 and the second locking blocks 47 are connected by the fourth connecting rods 53 that are hingedly installed.

[0035] When the sample box 31 in the mounting slot 30 is not filled with enough coal, the locking block 47 is inserted into the locking slot under the action of the spring 49, thereby locking the height of the first support plate 28. At this time, the lifting block 39 is in the high position, and the adjusting plate 42 is in the vertical position under the action of the connecting rod 40. At this time, the coal falling from the third discharge port 50 will fall into the sample box 31 below. When the sample box 31 is filled with enough coal, the sliding seat 45 will move towards each other. Then, under the action of the connecting rod 48, the locking blocks 47 at both ends move towards each other and disengage from the locking slot, thereby releasing the vertical lock on the first support plate 28. Under the action of gravity, the first support plate 28 moves downward. This causes the lifting block 38 to drive the lifting block 39 downwards, which in turn adjusts the angle of the adjusting plate 42 via the connecting rod 40. This causes the adjusting plate 42 to rotate towards the third discharge port 50, allowing the coal falling from the third discharge port 50 to land on the adjusting plate 42 and then directly onto the second support plate 29 before falling into the residual coal scattering assembly. This prevents the coal from continuously impacting the sample box 31, extending its service life. After collecting enough coal in the sample box 31, the angle of the adjusting plate 42 is automatically adjusted without manual monitoring. This ensures that a sufficient amount of sample remains in the sample box 31 and allows for timely adjustment of the coal flow direction, minimizing the number of impacts on the sample box 31.
