DETAILED DESCRIPTION

[0016] Embodiment 1: like Figures 1 to 3 A material drilling sampling device comprises a drill rod 10 and a suction sleeve 20 , wherein the drill rod and the suction sleeve are mounted on a sampling seat 30 .

[0017] The lower end of the drill rod 10 is provided with a drill bit 11. The drill rod is mounted on a sampling seat 30 via a bearing 33. The sampling seat 30 is provided with a motor 31 for driving the drill rod to rotate. The drill rod 10 drives the drill bit 11 to rotate.

[0018] The suction sleeve 20 is sleeved on the drill rod 10, and a suction port 21 is provided at the lower end of the suction sleeve. The drill bit 11 protrudes out of the suction port 21 and rotates.

[0019] In order to prevent the suction sleeve 20 from rotating with the drill rod 10, the suction sleeve 20 is connected to the drill rod 10 in rotation. The drill rod is provided with a suction sleeve clamp 12, which is fixedly connected to the drill rod 10. The suction sleeve clamp 12 has two slips, which are fastened to the drill rod 10 by bolts 15, and the suction sleeve clamp 12 rotates with the drill rod 10. An suction sleeve inner ring 22 is sleeved on the drill rod, and the suction sleeve clamp 12 is provided with a clamping groove 13. The suction sleeve inner ring 22 is provided with a hanging groove 23, and the clamping groove 13 and the hanging groove 23 are nested with each other, and the clamping groove 13 hangs the suction sleeve inner ring 22. The suction sleeve inner ring 22 and the drill rod 10 are clearance-matched to avoid excessive friction between the suction sleeve inner ring 22 and the drill rod 10, and the suction sleeve inner ring 22 can rotate and move axially on the drill rod. A rolling bearing 24 is provided between the suction sleeve inner ring 22 and the suction sleeve 20. In this embodiment, two rolling bearings are arranged between the suction sleeve inner ring 22 and the suction sleeve 20 . The suction sleeve inner ring 22 supports the bearing 24 at the lower end, and the suction sleeve 20 is fixedly connected to the bearing 24 axially by a retaining ring 25 .

[0020] In a natural state, the drill bit 11 protrudes from the lower end of the suction port 21. The clamping groove 13 and the hanging groove 23 both have a certain length, and the suction sleeve inner ring 22 can move axially along the clamping groove 13, so that the suction sleeve 20 can move axially with respect to the drill rod 10. The distance of the axial telescopic movement of the suction sleeve 20 with respect to the drill rod 10 can be controlled within the range of 20 mm to 30 mm.

[0021] The suction sleeve clamp 12 is provided with a blocking cover 14 covering the upper end of the suction sleeve, and the blocking cover 14 can protect the rolling bearing 24 in the suction sleeve 20.

[0022] The suction port 21 is a suction port of a bell mouth structure, and the suction port 21 is connected to a suction pipe 40, and the suction pipe 40 is connected to the suction port at the side wall of the suction port 21. In order to make the suction airflow smooth and make the suction port 21 easy to extend into the material, the connection angle α between the suction pipe and the suction port should not be greater than 25°.

[0023] The sampling seat 30 is provided with a suction tube guide sleeve 32 , and the suction tube 40 can move in the suction tube guide sleeve 32 .

[0024] The suction tube 40 is connected to the sampling tube 41, which is a flexible tube. The sampling tube 41 is connected to a vacuum source to suck material samples to achieve material sampling.

[0025] The sampling device of this embodiment is used to extract powder material samples. In order to smoothly absorb powder materials and prevent the inhalation of block materials, the gap between the drill bit 11 and the suction port 21 should be controlled to be 8mm to 10mm. In this embodiment, the drill bit 11 is a down-the-hole drill with a diameter d of 72mm, the inner diameter D of the suction port 21 is 90mm, and the gap between the drill bit 11 and the suction port 21 is 9mm.

[0026] In the process of extracting samples, when encountering large pieces of material (such as large pieces of ore), the drill rod 10 will be started, and the drill bit 11 will be driven into the material. Since the suction port 21 can be axially telescopically moved relative to the drill rod 10, the suction port 21 will be close to the material with the drill bit, and the powdered material or finely crushed material cut by the drill bit will be sucked into the suction port 21. Figure 4 shown.

[0027] When encountering the joint position of multiple pieces of material, such as Figure 5 As shown, the drill bit 11 is rotated, and the drill bit and the suction port 21 can move downward and be inserted into the material pile from the gap between the materials. The drill bit 11 can cut out some powdered materials which can be sucked by the suction port 21, and the powdered materials and finely divided materials in the material pile can also be sucked by the suction port 21, so as to realize the extraction of material samples.

[0028] The material drilling sampling device of the present invention can adapt to the sampling and extraction of materials in various states, including large and small block materials, powdered materials and mixed materials, has high operational reliability, and is conducive to realizing automated material sampling.

[0029] Embodiment 2: like Figure 6 , Figure 7 A mechanical sampling system for a truck scale includes a material drilling sampling device, a sampling manipulator 50, a lateral movement device 60, an intermediate sample storage box 70 and a vacuum sample collection device 80.

[0032] The material drilling sampling device is installed on the sampling manipulator 50, and the sampling seat 30 of the material drilling sampling device is connected to the sampling manipulator. The sampling manipulator 50 can drive the material drilling sampling device to move in six-dimensional space, reach various positions and obtain various postures. The sampling manipulator drives the material drilling sampling device to move between the carriage and the vacuum sample collection device.

[0033] The sampling manipulator 50 is installed on the transverse device 60, which includes a transverse workbench 61 and a transverse guide rail 62. The transverse guide rail is provided with a transverse rack 63. The transverse workbench is driven by a gear meshing with the transverse rack to move along the transverse guide rail. The transverse device 60 drives the sampling manipulator 50 to move, expanding the range of motion of the sampling manipulator 50 and the material drilling sampling device, and can perform multi-point sampling operations on larger carriages.

[0034] The intermediate sample storage box 70 is installed on the transverse working table 61 and moves synchronously with the sampling manipulator 50. The intermediate sample storage box 70 is connected to a vacuum pump 71 installed on the transverse working table 61 through a pipeline, and the intermediate sample storage box 70 is also connected to the sampling tube 41 of the material drilling sampling device through a pipeline. Under the action of the vacuum pump 71, the material drilling sampling device sucks the sample and sends it into the intermediate sample storage box 70.

[0035] The vacuum sample collection device 80 is provided with a sample barrel 81, and a plurality of sample barrels 81 are arranged on a sample turntable 82. The sample turntable 82 is a circular turntable, and a plurality of sample barrels 81 are distributed circumferentially on the sample turntable. The intermediate sample storage box 70 corresponds to a sample barrel 81 entering the receiving position each time, and delivers the material sample sucked from the material drilling sampling device into the corresponding sample barrel 81.

[0036] The mechanical sampling system of the truck scale is provided with a positioning and identification control device, which includes a 2D identification and positioning device and a 3D identification and positioning device. The 2D identification and positioning device is provided with a 2D camera 91, which identifies the position information of the carriage and moves the sampling manipulator and the material drilling and sampling device to the working position corresponding to the carriage. The 3D identification and positioning device 92 is installed on the material drilling and sampling device, which is provided with a 3D camera, which identifies the material position information and selects the appropriate sampling position.

[0037] The truck scale mechanical sampling system is equipped with a control system, which is responsible for the overall control of the system. The control system is connected to the upper-level production and transportation management information system. Through information interconnection, material transportation information can be recorded in real time, and the corresponding samples can be extracted into the sample barrel.

[0038] The operation of the truck scale mechanical sampling system of this embodiment includes the following steps: Step 1: After the material transport vehicle enters the truck scale, the 2D identification and positioning device analyzes the position information of the carriage and determines that the carriage enters the sampling position.

[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 barrel 81 according to the sample information transmitted from the production and transportation management information system, and rotates the selected sample barrel to the receiving position.

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

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

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

[0044] Step 7: The vacuum pump 71 is started to suck samples into the intermediate sample storage box 70 through the suction tube 40 and the sampling tube 41. To ensure the representativeness of the samples, samples can be extracted at multiple sampling positions in the carriage.

[0045] Step 9: After sampling is completed, the transverse working table 61 is moved to the sampling position, and the sample is transported from the intermediate sample storage box to the sample barrel, and then waits for the arrival of the next truck of samples.

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

[0047] The present invention can reduce the intervention of personnel, complete the automatic identification and positioning function of the equipment, the sample displacement detection function, the automatic sampling of the robot, and the sample information content can be queried at any time.

[0048] The existing sampling equipment extracts powdered samples on the mine car, but cannot be well adapted to the sampling of samples with large pieces of materials. The equipment of the present invention can be used for sampling powdered materials, and can also meet the sampling requirements of large and small pieces of materials, and can also avoid sample confusion during the sampling process.
