[0025] The outside of liquid inlet pipe 208 and liquid outlet pipe 209 is provided with one-way valve 2010, the liquid outlet end of one-way valve 2010 outside liquid inlet pipe 208 faces sampling cylinder 1, the liquid outlet end of one-way valve 2010 outside liquid outlet pipe 209 faces away from sampling cylinder 1, two one-way valves 2010 are arranged in opposite directions, which provides convenience for the detection and sampling of grain and oil,

[0026] Four groups of sampling barrels 1 are located below the liquid outlet pipe 209, and the side outer wall of the lowermost sampling barrel 1 is provided with an inclined backflow groove, and the length of the backflow groove is in an increasing distribution. The design of the backflow groove plays an auxiliary guiding effect on the subsequent discharge of grain oil. The increasing distribution enables the grain oil near the upper end to flow smoothly to the next layer through the guiding effect of the backflow groove, and finally, the grain oil is discharged in a concentrated manner.

[0027] The side outer wall of the positioning cylinder 202 is circumferentially provided with a positioning hole 2011, and the side outer wall of the positioning support seat 201 is provided with a butt joint hole 2012.

The counterweight 303 is designed to increase the overall weight of the device, enabling it to overcome the buoyancy of the grain oil and stand stably in the grain oil.

[0029] The cross section of the positioning cylinder 202 is designed as a "π" structure. The upper end of the positioning cylinder 202 is designed as a rotating end. The side outer wall of the rotating end of the positioning cylinder 202 is circumferentially provided with a vertical anti-slip strip.

[0030] Working principle: refer to the attached Figure 5 The counterweight 303 is designed to increase the overall weight of the device, enabling it to stand stably in the grain oil for sampling and testing. The threaded ring 301 and the threaded column 302 are designed for easy disassembly and assembly of the counterweight 303. When disassembling, only need to rotate the counterweight 303 until the threaded column 302 at the top end is completely separated from the inside of the threaded ring 301. The installation is the same.

[0031] Refer to the attached Figure 1 -Appendix Figure 4When the oil sampling is needed, the device is first placed in the oil to be sampled, and the oil surface should not exceed the uppermost liquid inlet pipe 208, then the positioning cylinder 202 is rotated, and when the positioning cylinder 202 is rotated, the limiting ring 203 is automatically driven to slide in the annular sliding groove, thereby limiting and supporting the rotating track of the positioning cylinder 202, and when the positioning cylinder 202 is rotated, the single-way screw rod 205 is automatically driven to rotate and move up through the internal threaded groove, and then the single-way screw rod 205 rotates and moves up, thereby automatically driving the uppermost piston disc 204 to move up, and when the uppermost piston disc 204 moves up, the limiting rod 207 is automatically driven to move up, thereby synchronously driving the three groups of lower piston discs 204 to move up, and when the four groups of piston discs 204 synchronously move up, the single-way valve 2010 outside the liquid inlet pipe 208 is automatically opened, and the oil at different levels is respectively drawn into the interiors of the plurality of sampling cylinders 1, and when the piston disc 204 moves to the top end of the sampling cylinder 1, the sampling process is completed;

[0032] Subsequently, the pin shaft 2013 is inserted through the positioning hole 2011 at the corresponding position and inserted into the bottom end of the butt joint hole 2012, and then the positioning cylinder 202 changes from the movable state to the locked state, thereby preventing the subsequent positioning cylinder 202 from being mis-rotated to cause the oil leakage phenomenon;

[0033] When the sampled oil needs to be discharged from the interior of the device, the pin shaft 2013 is first completely pulled out from the interior of the positioning hole 2011, and then the positioning cylinder 202 is rotated in the opposite direction of the above sampling, and the principle is the same as above, at this time, the four groups of piston discs 204 synchronously move down, and then the single-way valve 2010 outside the liquid outlet pipe 209 is automatically opened, and the oil sampled in the four groups of sampling cylinders 1 is discharged, and if the oil is collected in a single layer, a plurality of containers can be used for separate collection, and if the oil is uniformly detected and normally discharged, it can be directly discharged;

[0034] The sampling oil amount can be directly controlled by adjusting the moving height of the piston disc 204 during sampling, and the more the sampling amount is, the higher the final sampling amount is, and the less the sampling amount is, the lower the final sampling amount is;

[0035] The above is the working process of the entire device, and the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0036] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
