Description

Technical Field

[0001] The utility model relates to the field of slag detection, in particular to a sampling device for detecting slag pollutants. Background Art

[0002] The construction process of slag is divided into construction preparation, slag transportation, three-stage vibrating screen screening, spiral sand washing machine separation, tailings recovery integrated machine treatment, sewage transfer pool collection, sewage treatment tank reaction flocculation, filter press pressing and final pressing into mud cake. When sampling slag pollutants, the sampling device is usually moved to the belt conveyor through a mobile device during the slag transportation process, and then the sampling device grabs the slag transported on the belt conveyor, and finally the staff will test the pollutants contained in the sample.

[0003] A Chinese patent with announcement number CN220473016U discloses a slag sampling bucket, a slag sampling device and a shield machine. When in use, the push plate drive device can be first installed on the push plate drive device installation position. During the swing sampling and unloading process of the sampling bucket, the push plate drive device is positioned close to the hinge point of the sampling bucket, and part of it is located within the swing range of the sampling bucket drive device, which is equivalent to shortening the lever arm from the overall center of gravity of the sampling bucket to the hinge position of the sampling bucket drive device. At the same time, the driving lever arm of the sampling bucket drive device partially extends to the push plate drive device. Compared with the prior art, the slag sampling bucket in the utility model has better stability and is suitable for slag sampling in shield machines.

[0004] However, this patent sets up multiple driving devices in the actual implementation work, and uses multiple driving devices to perform slag sampling, which requires workers to spend a lot of time in the installation and maintenance process. There is a lack of a mechanism that can complete sampling through a single driving device, resulting in a significant increase in the cost of equipment implementation. Utility Model Content

[0005] The utility model is intended to provide a sampling device for detecting slag pollutants, which is mainly used to solve the technical problem that the existing technology lacks a mechanism that can complete sampling through a driving device, resulting in a significant increase in the cost of equipment implementation.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] 1. Working principle: The driving mechanism can drive the sampling bucket to rotate counterclockwise, so that the sampling bucket rotates on the outer wall of the barrier, and one end of the barrier moves to the inlet of the trough. At the same time, the driving mechanism drives the reeling and unreeling mechanism to rotate, thereby unreeling the connecting member, so that the connecting member releases its support for the guide mechanism, so that the guide mechanism slides downward on the limiting member, so that one end of the guide mechanism rotates out from under the sampling bucket, and then the mounting column is moved to the external belt conveyor through the external moving device. At this time, the driving mechanism drives the sampling bucket to rotate clockwise, so that the sampling bucket drives the guide mechanism to dig the soil on the belt conveyor into the trough. In this process, the sampling bucket gradually resets, and the reeling and unreeling mechanism drives the connecting member to reel, so that the guide mechanism also gradually resets, and one end of the barrier moves to the middle of the trough.

The driving mechanism includes a motor 4 and a connecting rod 5. The motor 4 is installed on one side of the connecting plate 3. The output end of the motor 4 is fixedly connected to the connecting rod 5. The outer wall of the connecting rod 5 can rotatably pass through both sides of the mounting column 1. The two sides of the top of the sampling hopper 7 are fixedly connected to the outer wall of the connecting rod 5, and the two sides of the sampling hopper 7 are close to both sides of the mounting column 1.

The outer wall of the connecting rope 12 passes through the protective box 14 and contacts the outer wall of the guide wheel 18, and one end of the connecting rope 12 is wound inside the reeling and unwinding mechanism;Start the motor 4, so that the output shaft of the motor 4 drives the connecting rod 5 to rotate counterclockwise, thereby driving the sampling bucket 7 to rotate toward the rear side of the mounting column 1. At this time, the connecting rod 5 also drives the reel-up wheel 6 to rotate counterclockwise, thereby unwinding the connecting rope 12, so that the outer wall of the connecting rope 12 slides on the outer wall of the guide wheel 18. Due to the weight of the guide plate 10 itself, the connecting rope 12 causes one end of the guide plate 10 to rotate inside the material trough 8, and the other end drives the fixed rod 9 to rotate downward inside the guide groove 13, and the fixed rod 9 drives the rotating ring 11 and the connecting rope 12 to rotate downward, thereby releasing the support for the guide plate 10.

Due to the effect of the protective box 14, the slag is prevented from affecting the movement of the fixing rod 9 in the guide groove 13. As the sampling bucket 7 gradually resets, the retractable reel 6 is driven to reel in the connecting rope 12, so that the guide plate 10 is reset, thereby facilitating the confinement of the sample in the sampling bucket 7.

[0026] The barrier is arranged on the rear side of the mounting column 1, and the barrier passes through the inner wall of the trough 8, and the sampling hopper 7 is slidably connected to the barrier, and one end of the barrier is located inside the trough 8 and fits the inner wall of the sampling hopper 7; the barrier includes a support plate 15, a special-shaped plate 16 and a push plate 17, one end of the support plate 15 is fixedly connected to the rear side of the mounting column 1, one end of the support plate 15 is fixedly connected to the special-shaped plate 16, the special-shaped plate 16 passes through the rear side of the sampling hopper 7 and extends to the inside of the trough 8, one end of the special-shaped plate 16 is fixedly connected to the push plate 17 near the inside of the trough 8, and the outer wall of the push plate 17 is adapted to the inner wall of the trough 8; start the motor 4 so that the output shaft of the motor 4 drives the connecting rod 5 to rotate counterclockwise, thereby The connecting rod 5 drives the sampling bucket 7 to rotate toward the rear side of the mounting column 1, and the sampling bucket 7 rotates on the outside of the special-shaped plate 16, so that the push plate 17 moves to the entrance of the trough 8, and the motor 4 is started again, so that the motor 4 drives the connecting rod 5 to rotate clockwise, so that the sampling bucket 7 is reset. At this time, the push plate 17 moves to the middle of the trough 8, so that the sampling bucket 7 is reset, and the sampling bucket 7 drives the guide plate 10 to dig and sample the slag on the external belt conveyor. In addition, when the external mobile device drives the mounting column 1 to move out of the belt conveyor, it can be rotated counterclockwise by the motor 4 again, so that when the sampling bucket 7 rotates counterclockwise, the push plate 17 will fully scrape the sample in the sampling bucket 7 out of the sampling bucket 7.

[0027] From the above, it can be seen that the specific implementation of the present invention is as follows: the mounting post 1 can be installed in an external mobile device through the mounting plate 2, and the motor 4 is started so that the output shaft of the motor 4 drives the connecting rod 5 to rotate counterclockwise, thereby driving the sampling bucket 7 to rotate toward the rear side of the mounting post 1. At this time, the connecting rod 5 also drives the reel-up wheel 6 to rotate counterclockwise, thereby unwinding the connecting rope 12, so that the outer wall of the connecting rope 12 slides on the outer wall of the guide wheel 18. Due to the weight of the guide plate 10 itself, the connecting rope 12 causes one end of the guide plate 10 to rotate inside the material trough 8, and the other end drives the fixed rod 9 to rotate downward inside the guide groove 13, and the fixed rod 9 drives the rotating ring 11 and the connecting rope 12 to rotate downward, thereby releasing the support for the guide plate 10, so that the other end of the guide plate 10 rotates to the bottom of the sampling bucket 7. At the same time, the sampling bucket 7 rotates outside the special-shaped plate 16 The push plate 17 moves to the entrance of the trough 8. When the external equipment drives the mounting column 1 to move to the external belt conveyor, the motor 4 is started again, so that the motor 4 drives the connecting rod 5 to rotate clockwise, so that the sampling bucket 7 is reset. At this time, the push plate 17 moves to the middle of the trough 8, so that the sampling bucket 7 drives the guide plate 10 to dig and sample the slag on the external belt conveyor. Due to the action of the protective box 14, the slag is prevented from affecting the movement of the fixed rod 9 inside the guide groove 13, and because the sampling bucket 7 is gradually reset, it drives the reel-and-unreel wheel 6 to reel in the connecting rope 12, so that the guide plate 10 is reset, thereby facilitating the sample to be confined in the sampling bucket 7. In addition, when the external moving device drives the mounting column 1 to move out of the belt conveyor, it can be rotated counterclockwise again by the motor 4, so that when the sampling bucket 7 rotates counterclockwise, the push plate 17 will fully scrape the sample in the sampling bucket 7 out of the sampling bucket 7.
