Description

Technical Field

[0001] This utility model relates to vehicle material sampling technology, and more particularly to an automatic sampling system for vehicle compartments. Background Technology

[0002] With technological advancements, workers' working conditions and labor intensity have improved. In areas with harsh environments, high labor intensity, and repetitive tasks, robots are needed to replace manual labor. This reduces manual labor intensity, ensures worker safety, lightens workload, and minimizes problems caused by information errors. Traditional manual vehicle sampling requires workers to enter the vehicle to collect samples, then confirm the data via telephone before recording it. This is labor-intensive, requires extensive preparation, and the sampling locations are generally harsh. Prolonged manual labor can cause physical harm to workers, and data entry errors can also lead to problems. Furthermore, manual sampling is susceptible to human intervention, which can introduce errors into the results. Utility Model Content

[0019] Example 1:

[0020] like Figures 3 to 5 A material drilling and sampling device includes a drill rod 10 and a suction sleeve 20, which are mounted on a sampling seat 30.

[0021] The lower end of the drill rod 10 is provided with a drill bit 11. The drill rod is mounted on the sampling seat 30 via a bearing 33. The sampling seat 30 is provided with a motor 31 that drives the drill rod to rotate, and the drill rod 10 drives the drill bit 11 to rotate.

[0022] The suction sleeve 20 is fitted onto the drill rod 10. The lower end of the suction sleeve is provided with a suction port 21, and the drill bit 11 extends out of the lower end of the suction port 21. The drill rod 10 drives the drill bit 11 to rotate.

[0023] To prevent the suction sleeve 20 from rotating with the drill rod 10, the suction sleeve 20 is rotatably connected to the drill rod 10. The drill rod is equipped with a suction sleeve clamp 12, which is fixedly connected to the drill rod 10. The suction sleeve clamp 12 has two jaws, fastened to the drill rod 10 by bolts 15. The suction sleeve clamp 12 rotates with the drill rod 10. A suction sleeve inner ring 22 is fitted onto the drill rod. The suction sleeve clamp 12 has a groove 13, and the suction sleeve inner ring 22 has a hooking groove 23. The groove 13 and the hooking groove 23 are nested together, and the groove 13 suspends the suction sleeve inner ring 22. The suction sleeve inner ring 22 and the drill rod 10 are clearance-fitted to avoid excessive friction between them. The suction sleeve inner ring 22 can rotate and move axially on the drill rod, allowing the suction sleeve 20 to move appropriately axially relative to the drill rod 10. A rolling bearing 24 is provided between the suction sleeve inner ring 22 and the suction sleeve 20.

[0027] Example 2

[0028] like Figure 1 , Figure 2 An automatic sampling system for a train carriage includes a material drilling and sampling device (10-40), a sampling robot 50, a lateral movement device 60, an intermediate sample storage box 70, and a sample collection device 80.

[0029] The material drilling and sampling device is the material drilling and sampling device described in Example 1.

[0030] The sampling manipulator is a six-axis manipulator (or six-axis robotic arm, six-axis robot).

[0031] The material drilling and sampling device is mounted on the sampling robot 50, and the sampling seat 30 of the material drilling and sampling device is connected to the sampling robot. The sampling robot 50 can drive the material drilling and sampling device to move in six-dimensional space, reach various positions, and obtain various postures. The sampling robot 50 drives the material drilling and sampling device to move between the carriage and the intermediate sample storage box 70.

[0032] The sampling robot 50 is mounted on a transverse movement device 60, which includes a transverse worktable 61 and a transverse guide rail 62. The transverse guide rail is equipped with a transverse rack 63. The transverse worktable is driven to move along the transverse guide rail by a gear meshing with the transverse rack. The transverse movement device 60 moves the sampling robot 50, expanding the range of motion of the sampling robot 50 and the material drilling and sampling device, enabling multi-point sampling operations in larger carriages.

[0033] The intermediate sample storage box 70 is provided with a vacuum chamber 72, a sample collection chamber 73 and a discharge valve 74. A filter screen is provided between the vacuum chamber 72 and the sample collection chamber 73. The vacuum chamber is connected to a vacuum pump 71. The vacuum chamber 72 is provided with a vacuum chamber interface 75 for connecting to the vacuum pump 71. The sample collection chamber 73 is provided with a sample collection interface 76. The sample collection interface 76 is connected to the sampling tube 41 of the material drilling and sampling device. The lower end of the intermediate sample storage box is provided with a discharge port 77. The discharge valve 74 controls the sample in the sample collection chamber 73 to be output through the discharge port 77.

[0034] The sample collection device 80 receives material samples from the intermediate sample storage box 70. The sample collection device 80 is equipped with sample containers 81, and multiple sample containers 81 are arranged on a sample turntable 82. The sample turntable 82 is a circular rotary table, and the multiple sample containers 81 are distributed circumferentially on the sample turntable. The intermediate sample storage box 70 receives one sample container 81 at a time, corresponding to the sample container 81 that has entered the receiving position, and delivers the material sample extracted by the material drilling and sampling device into the corresponding sample container 81.

[0035] The automatic sampling system for the carriage is equipped with a positioning and identification control device, which includes a 2D positioning device and a 3D positioning device. The 2D positioning device is equipped with a 2D camera 91, which identifies the carriage's position information and moves the sampling robot and material drilling and sampling device to the corresponding working position within the carriage. The 3D positioning device 92 is installed on the material drilling and sampling device and is equipped with a 3D camera. The 3D positioning device identifies the material's position information and selects an appropriate sampling location.

[0036] The automatic sampling system in the carriage is equipped with a control system responsible for controlling the overall operation of the system. This control system is interconnected with a higher-level production and transportation management information system. Through this information interconnection, material transportation information can be recorded in real time, and corresponding samples can be extracted into the sample container.

[0037] The operation of the automatic sampling system for the carriage in this embodiment includes the following steps:

[0038] Step 1: After the material transport vehicle enters the weighbridge, the 2D recognition and positioning device analyzes the position information of the truck bed and determines the sampling location of the truck bed.

[0039] Step 2: The control system sends the carriage information to the upper-level production and transportation management information system.

[0040] Step 3: The control system selects a suitable sample container 81 based on the sample information transmitted from the production and transportation management information system and rotates the selected sample container to the receiving position.

[0041] Step 4: Based on the position information provided by the 2D recognition and positioning device, the lateral movement device drives the sampling robot 50, the material drilling and sampling device, and the intermediate sample storage box 70 to the appropriate operating position.

[0042] Step 5: The 3D recognition and positioning device 92 identifies the location of the sampled material and sends the coordinate information to the sampling robot.

[0043] Step 6: The sampling robot moves the material drilling and sampling device so that the drill bit 11 is aligned with the sampling position, the drill rod 10 starts to rotate, and the drill bit 11 drills into the material.

[0044] Step 7: Vacuum pump 71 is started. Under vacuum, the material sample enters the sample collection chamber 73 of the intermediate sample storage box through suction tube 40 and sampling tube 41. In order to ensure the representativeness of the sample, the sample can be extracted from multiple sampling positions in the carriage.

[0045] Step 9: After sampling is completed, the transverse worktable 61 is moved to the sampling position, the discharge valve 74 is opened, and the sample in the sample collection chamber 73 is transported to the sample barrel 81 through the discharge port 77, and then waits for the next batch of samples to arrive.

[0046] Step 10: Start the vacuum pump 71 to perform a backflush operation, backflush the samples in the sampling pipeline and intermediate sample storage box to prevent sample confusion in the next sampling.

[0047] This invention can be installed at a truck scale for managing material transportation, or in other material transportation systems, such as railway material transportation systems.

[0048] This invention can reduce human intervention, complete the automatic identification and positioning function of equipment, the sample displacement detection function, the automatic sampling by robot, and the sample information can be queried at any time.

[0049] Existing sampling equipment extracts powdery samples from mine carts, but it is not well-suited for sampling samples containing large pieces of material. This new device can be used for sampling both powdery and large-sized materials, and it also solves the problem of sample mixing during the sampling process.
