[0002] In the process of process control in the ore dressing plant, it is necessary to conduct slurry sampling and analysis on the grinding and ore dressing operations to detect the concentration, fineness, and grade of ore in each operation section in the ore dressing process. The liquid reciprocating sampler is a commonly used sampling machine in mining enterprises. It is used for sampling liquid materials after ore grinding. Therefore, the liquid reciprocating sampler is an important equipment in the ore dressing plant and an important part of the ore dressing analysis and research in the ore dressing plant. The working principle of the reciprocating sampler is that the motor drives the chain, and the chain drives the sampling spoon to reciprocate on the guide bar and uniformly cross-cut the ore slurry flow for sampling.

[0003] It was found during use that as long as the process is started, the sampler motor must run continuously and take samples continuously. The amount of samples taken is large, which not only affects the processing and representativeness of the samples.

After adjusting to a suitable position, the user can turn the second locking screw 82 so that the top of the second locking screw 82 abuts against the bottom of the catheter 51, thereby limiting the catheter 52 and the sampling spoon 5.

[0035] Compared with the related art, the time relay control sampling device and method provided by the present invention has the following beneficial effects: Through the cooperation of the mounting block 8, the mounting groove 81 and the second locking screw 82 and other structures, when in use, the catheter 51 can be inserted into the inner side of the mounting groove 81, and then the top of the second locking screw 82 is made to abut against the bottom of the catheter 51. This not only can limit the catheter 51 and the sampling spoon 5, but also makes it convenient for the user to adjust the position of the sampling spoon 5 and the catheter 51.

[0036] To solve the above problems, the present invention also provides a time relay control sampling method, comprising the following steps: S1. When in use, the device is installed at the position where the slurry flows, so that the sampling spoon 5 can be located at the position where the slurry flows; S2, then start the driving motor 61, so that the driving motor 61 drives the active pulley 62 to rotate, so that the active pulley 62 drives the belt 63 to rotate, and then the belt 63 drives the driven pulley 64 to rotate, and then the driven pulley 64 drives the reducer 65 to rotate, so that the output end of the reducer 65 drives one of the sprockets 23 to rotate, and when the sprocket 23 rotates, it can drive the chain 23 meshing on the surface to move; S3. When the chain 23 moves, it can drive the moving component 3 to move, so that the moving component 3 slides on the outer side of the slide bar 21 to one end, and drives the sampling spoon 5 to move at the bottom of the slurry flow, so that the slurry enters the interior of the conduit 51 through the sampling spoon 5, and then is discharged through the conduit 51. When one side of the moving block 31 abuts against one side of one of the travel switches 73, a sampling is completed, and at the same time, the driving motor 61 will stop rotating. At this time, the time relay 4 will start timing. When the preset time is reached, the driving motor 61 will reverse, so that the moving block 31 abuts against the side of another travel switch 73, thereby completing a sampling operation again.
