Description

Technical Field

[0001] The utility model relates to the technical field of gold tailings sampling, in particular to a gold tailings sampling device. Background Art

[0002] Gold tailings are one of the products of sorting operations in mineral processing. The part with the lowest useful target gold content is called gold tailings. The gold tailings transfer pool is a storage pool for centralized testing of tailings. In order to determine whether the slag in the pool meets the tailings standards, it is necessary to sample the ore sand in the gold tailings transfer pool for testing. Nowadays, sampling is usually carried out manually. During the sampling process, workers may fall into the transfer pool, which is not conducive to their own safety. After sampling, a large amount of debris will stick to the surface of the sampling instrument. The debris will be mixed into the sample, which will affect the inspection results.

[0003] The existing Chinese patent with publication number CN218271498U discloses a gold tailings transfer pool sampling device, including a mounting plate, a fixing sleeve connected to the top of the mounting plate by bolts, a flushing mechanism provided on the surface of the mounting plate, and a fixing cover connected to the top of the fixing sleeve by bolts. The utility model has the advantages of automatic sampling and surface cleaning through the coordinated use of support legs, a connecting plate, a water tank, a water pump, a water spray ring, a fixing sleeve, a fixing cover, a first servo motor, a turntable, a second servo motor, a threaded rod, a movable block, a third servo motor, a rotating rod, a sampling box, a connecting rod, a baffle and a controller, thereby solving the problem that sampling is usually performed manually today, during which workers may fall into the transfer pool, which is not conducive to their own safety, and after sampling, a large amount of debris will stick to the surface of the sampling instrument, which will be mixed into the sample and affect the inspection results.

[0004] Although this existing technology solves the problem that sampling is usually done manually today, workers may fall into the transfer pool during the sampling process, which is not conducive to their own safety. After sampling, a large amount of debris will stick to the surface of the sampling instrument, and the debris will be mixed into the sample, which will affect the inspection results. However, after the sampling is completed, it is necessary to manually pull the connecting rod to open the baffle to remove the sample, which is too troublesome. In addition, there are certain safety hazards as the workers work under the sampling equipment. Utility Model Content

DETAILED DESCRIPTION

[0025] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] The present invention is further described in detail below with reference to the embodiments:

[0027] like Figure 1-5 As shown, the utility model provides a gold tailings sampling device, including a support frame 1, a rotating base 2, a sampling barrel 3 and a hydraulic rod 11. The outer wall of the sampling barrel 3 near the bottom end is provided with an inclined sampling hole 4, and the angle formed between the sampling hole 4 and the central axis of the sampling barrel 3 is an acute angle. The inner wall of the sampling barrel 3 near the bottom end is movably connected to a closing component for sealing it and can be pushed to open.

[0028] The inner wall of the sampling tube 3 is rotatably connected to the stirring and discharging rod 13 via a positioning collar 16. The outer wall of the stirring and discharging rod 13 located below the positioning collar 16 is fixedly connected to a fixing collar 18. The upper surface of the fixing collar 18 is rotatably connected to a return spring 17. The top end of the return spring 17 is rotatably connected to the bottom surface of the positioning collar 16. When the stirring and discharging rod 13 is pushed downward by the positioning plate 10, it drives the fixing collar 18 to stretch the return spring 17. When the sampling tube 3 is reset, the return spring 17 pulls the fixing collar 18 to reset the stirring and discharging rod 13. At the same time, when the bottom sealing plate 20 is pushed downward, it pulls the discharge return spring 22 through the side mounting block 23, causing the discharge return spring 22 to stretch, generating a reaction force. When the sampling tube 3 is subsequently reset, the bottom sealing plate 20 is pulled to re-seal the sampling tube 3.

[0029] The top outer wall of the sampling tube 3 is fixedly connected to a sampling outer gear 15, and the sampling outer gear 15 is engaged with the first transmission gear 8. The upper surface of the first transmission gear 8 is fixedly connected to the second transmission gear 9 through a connecting rod. The second transmission gear 9 is engaged with a stirring gear 12 fixedly connected to the top outer wall of the stirring and discharging rod 13. A positioning plate 10 is provided above the stirring and discharging rod 13.

[0030] When it is necessary to discharge the sample in the sampling cylinder 3, the control drive motor 7 is stopped, and then the hydraulic rod 11 is started, so that the hydraulic rod 11 drives the sampling cylinder 3 to move upward continuously. During the upward movement of the sampling cylinder 3, the stirring and discharging rod 13 moves upward accordingly. When the top of the stirring and discharging rod 13 contacts the positioning plate 10, the sampling cylinder 3 continues to move upward. At this time, when the stirring and discharging rod 13 contacts the upper surface of the bottom sealing plate 20, it will push the bottom sealing plate 20 to move downward at the bottom end of the sampling cylinder 3, releasing the closed state of the bottom end of the sampling cylinder 3. At this time, the sample in the sampling cylinder 3 can be discharged from the bottom outlet, and subsequent collection and analysis work can be carried out. During the up and down movement of the stirring and discharging rod 13, the stirring gear 12 always remains in meshing with the second transmission gear 9.

[0031] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the angle formed by the sampling hole 4 and the central axis of the sampling tube 3 is an acute angle, one end of the positioning plate 10 is fixedly connected to the top of the support frame 1, and the outer wall of the bottom end of the stirring and discharging rod 13 is fixedly connected with a stirring tooth 19.

[0032] The closing assembly includes a fixed bottom sealing plate 20 and a blanking return spring 22. The bottom end of the blanking return spring 22 is fixedly connected to a side mounting block 23. The inner wall of the bottom end of the sampling tube 3 is provided with a guide blanking trough 21 for slidingly guiding the side mounting block 23. The top of the inner wall of the guide blanking trough 21 is fixedly connected to the top of the blanking return spring 22.

[0033] The outer wall of the sampling tube 3 is rotatably connected to the guide ring frame 6, the bottom end of the first transmission gear 8 is fixedly connected to the drive motor 7, the upper surface of the guide ring frame 6 is fixedly connected to the bottom surface of the drive motor 7, a guide groove 14 is provided on one side of the support frame 1, and the bottom end of the hydraulic rod 11 is fixedly connected to the upper surface of the guide ring frame 6 near one end.

[0034] The inner wall of the guide slot 14 is slidably connected to one end of the guide ring frame 6 via a slider.

[0035] A desilting ring frame 5 is provided on the outer wall of the sampling tube 3 near the bottom end, and one end of the desilting ring frame 5 away from the sampling tube 3 is fixedly connected to one side of the support frame 1.

[0036] The thickness of the stirring gear 12 is greater than the thickness of the second transmission gear 9 .

[0037] The working principle of the gold tailings sampling device is described in detail below.

[0038] like Figure 1-5As shown, during use, an external power supply activates the drive motor 7, causing the drive motor 7 to rotate the first transmission gear 8 and the second transmission gear 9. The first transmission gear 8 then rotates the sampling barrel 3 via the sampling outer gear 15. As the sampling barrel 3 rotates, the hydraulic rod 11 is activated, pushing the guide ring frame 6 to drive the sampling barrel 3 downward and drill into the tailings. As the sampling barrel 3 moves downward, the stirring and discharge rod 13 also moves downward. At the same time, driven by the second transmission gear 9, the stirring gear 12 drives the sampling barrel 3 to rotate.

[0039] When the sampling cylinder 3 moves down to the specified depth, the drive motor 7 is regulated to reduce its output power and the rotation speed of the sampling cylinder 3. At this time, the sample enters the sampling cylinder 3 through the sampling hole 4, and the stirring and discharging rod 13 in the sampling cylinder 3 is driven by the stirring gear 12 and continuously rotates at a rotation speed greater than the rotation speed of the sampling cylinder 3, stirring and mixing the sample entering the sampling cylinder 3 to prevent the sample from clogging the sampling hole 4 and facilitating the entry of subsequent samples. After the sampling cylinder 3 has completed sampling, the hydraulic rod 11 is started to drive the guide ring frame 6 to move up, driving the sampling cylinder 3 to be lifted up and reset from the tailings. During the upward movement of the sampling cylinder 3, the sampling cylinder 3 is in a rotating state to prevent debris attached to its outer wall from entering the sampling cylinder 3 through the sampling hole 4.

[0040] During the upward movement of the sampling tube 3 , the debris attached to the outer wall thereof will be scraped off by the mud removal ring frame 5 , so as to keep the outer wall thereof clean.

[0041] The outer wall of the blanking return spring 22 can be sleeved with a cloth bag that can fit its outer layer for protection.

[0042] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
