[0015] The present invention also provides a sampling and conveying method for oil additive production, comprising the sampling device for oil additive production as described above, comprising the following steps:

[0016] When it is necessary to rotate the threaded adjustment rotating column, the rotating adjustment plate is manually driven to rotate, thereby overcoming the resistance of the compression spring on the rotating adjustment plate, thereby causing the first limit plate to rotate, so that the first limit plate is no longer located on the side of the positioning anti-rotation gear plate away from the rotation limit gear, so that the connecting movable plate and the positioning anti-rotation gear plate can be moved, thereby driving the connecting movable plate to move relative to the second fixed plate, so that the positioning anti-rotation gear plate is no longer engaged with the rotation limit gear, and the threaded adjustment rotating column and the rotation limit gear can be rotated;

[0017] Then the threaded adjustment rotating column is driven to rotate, and the threaded adjustment rotating column and the movable adjustment lifting seat are matched to make the movable adjustment lifting seat move smoothly in the vertical direction relative to the sampling movable tube, so that the height of the movable adjustment lifting seat and the second sampling head can be adjusted, and the height of the two second sampling heads can be adjusted according to the actual sampling requirements;

[0018] When there is no need to rotate the rotation limit gear, the connected moving plate is driven to move again so that the positioning anti-rotation gear plate and the rotation limit gear are meshed, and then the rotation adjustment plate is manually driven to rotate so that the first limit plate moves to the side of the positioning anti-rotation gear plate away from the rotation limit gear.

[0019] The sampling active tube is inserted into the additive to be tested, and the sampling pump is started, so that the additive to be tested is transported into the sampling active tube through the first sampling head and the two second sampling heads, and then the additive to be tested is transported into the additive sampling collection box body through the first connecting hose and the liquid inlet tube, and different positions in the additive to be tested are sampled simultaneously;

[0020] The additive to be detected in the additive sampling and collecting box body is stirred by the uniform stirring and mixing component so that the additive to be detected is uniformly mixed, and then the uniformly mixed additive to be detected can be discharged through the discharge pipe according to demand.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) During operation, the sampling active tube is inserted into the additive to be tested, and the sampling pump is started, so that the additive to be tested is transported into the sampling active tube through the first sampling head and the two second sampling heads, and then the additive to be tested is transported into the additive sampling and collection box body through the first connecting hose and the liquid inlet pipe, and different positions in the additive to be tested are sampled simultaneously. The additive to be tested in the additive sampling and collection box body is stirred by the uniform stirring and mixing component, so that the additive to be tested is mixed evenly, and then the uniformly mixed additive to be tested can be discharged through the discharge pipe according to demand, thereby improving the accuracy of sampling measurement and making it more convenient to perform detection and sampling work;

[0023] (2) Drive the threaded adjustment rotating column to rotate. Through the cooperation of the threaded adjustment rotating column and the movable adjustment lifting seat, the movable adjustment lifting seat can move smoothly in the vertical direction relative to the sampling movable tube, so that the height of the movable adjustment lifting seat and the second sampling head can be adjusted. The height of the two second sampling heads can be adjusted according to actual sampling needs, and sampling can be performed at different positions. Before driving the threaded adjustment rotating column to rotate, the compression spring is in a compressed state. The compression spring applies pressure to the rotation adjustment plate to prevent the rotation adjustment plate from rotating and shaking relative to the rotation shaft, so that the first limit plate is always located on one side of the positioning anti-rotation gear plate. The first limit plate limits the position of the positioning anti-rotation gear plate to prevent the positioning anti-rotation gear plate from moving away from the rotation limit gear, so that the positioning anti-rotation gear plate and the rotation limit gear are meshed together, thereby making the rotation limit gear and the threaded adjustment rotating column maintain their current positions, preventing the threaded adjustment rotating column from rotating due to non-human factors. When the threaded adjustment rotating column needs to be rotated, the human The first limit plate is used to limit the position of the anti-rotation gear plate, thereby preventing the positioning anti-rotation gear plate from moving away from the rotation limit gear, and the second limit plate is used to limit the position of the anti-rotation gear plate, thereby preventing the positioning anti-rotation gear plate from moving away from the rotation limit gear.

[0024] (3) By driving the movable lifting adjustment ring to move upward, the tension spring is in a stretched state, thereby causing the bottom end of the plug plate to disengage from the slot, releasing the limit on the position of the limit movable card plate, and at the same time, the movable plate and the baffle plate move upward, and the bottom horizontal position of the baffle plate is at the same horizontal position as the top horizontal position of the second fixed plate, and by driving the movable plate and the baffle plate to move, the baffle plate moves to the top of the second fixed plate, and is supported by the baffle plate to prevent the movable lifting adjustment ring from moving downward relative to the fixed column, so that the movable lifting adjustment ring and the plug plate maintain the height at this time, and by the design of the anti-slip plate, the third support plate is prevented from disengaging from the fourth rectangular hole, and then the limit movable card plate is driven to move, so that one end of the limit movable card plate is disengaged from the card slot, and the fixing relationship between the second limit plate and the second support plate can be released, so that the second support plate can move up relative to the second limit plate, and then the cover of the sampling collection box is driven to move upward, so that the second support The plate follows the cover of the sampling and collection box to move up, thereby making the second limiting plate detach from the second rectangular hole, and the cover of the sampling and collection box can be removed, which is convenient for cleaning the inside of the additive sampling and collection box. When the cover of the sampling and collection box needs to be installed, the cover of the sampling and collection box is driven to move to the top of the additive sampling and collection box body, and the second limiting plate passes through the second rectangular hole, thereby making the card slot move to one side of the limiting movable card plate, and by driving the limiting movable card plate to move, one end of the limiting movable card plate is inserted into the card slot, thereby making the second limiting plate fixed relative to the second supporting plate, and the slot moves to just below the plug plate, thereby driving the baffle plate and the movable plate to move, so that the baffle plate no longer contacts the top of the second fixed plate, releasing the support for the movable lifting adjustment ring, and then stretching the spring to drive the movable lifting adjustment ring to move downward, so that the bottom end of the plug plate is inserted into the slot, and the position of the limiting movable card plate can be limited;

[0025] (4) The motor drives the fixed shaft to rotate, and then the fixed shaft drives the stirring shaft and the stirring blade to rotate. The stirring blade can stir the additive in the additive sampling and collection box body. When the sampling and collection box cover and the additive sampling and collection box body are separated, the bolts are driven to rotate so that the bolts are separated from the first connecting plate and the second connecting plate, and the separation between the first connecting plate and the second connecting plate can be completed, so that the stirring shaft and the fixed shaft are separated, which makes it easier to clean the stirring shaft and the stirring blade. The handle design makes it easier to drive the threaded adjustment rotating column to rotate. The observation window design makes it easier to observe the situation inside the additive sampling and collection box body. The sealing gasket design increases the sealing performance of the connection between the additive sampling and collection box body and the sampling and collection box cover.

[0043] The motor 34 drives the connecting fixed shaft 32 to rotate, and then drives the stirring shaft 30 and the stirring blade 31 to rotate through the connecting fixed shaft 32. The stirring blade 31 can stir the additive in the additive sampling and collection box body 1. When the sampling and collection box cover 2 and the additive sampling and collection box body 1 are separated, the bolt 37 is driven to rotate so that the bolt 37 is disengaged from the first connecting plate 35 and the second connecting plate 36, and the separation between the first connecting plate 35 and the second connecting plate 36 can be completed, so that the stirring shaft 30 and the connecting fixed shaft 32 are separated, which makes it easier to clean the stirring shaft 30 and the stirring blade 31. The design of the handle 27 makes it easier to drive the threaded adjustment rotating column 13 to rotate. The design of the observation window 29 makes it easier to observe the situation in the additive sampling and collection box body 1. The design of the sealing gasket 57 increases the sealing performance of the connection between the additive sampling and collection box body 1 and the sampling and collection box cover 2.

[0044] Embodiment 4, based on embodiment 1, Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7It is given that two first support plates 38 are fixedly connected to the additive sampling and collection box body 1, and two second support plates 39 are fixedly connected to the sampling and collection box cover 2. A second rectangular hole 40 is opened on the top of the second support plate 39, and a second limiting plate 41 is fixedly connected to the top of the first support plate 38. A card slot 42 is opened on one side of the second limiting plate 41. Two third fixed plates 44 are fixedly connected to the top of the sampling and collection box cover 2, and a third rectangular hole 45 is opened on one side of the third fixed plate 44. A limiting movable card plate 43 is arranged in the third rectangular hole 45, and both ends of the limiting movable card plate 43 extend to the outside of the third rectangular hole 45. A slot 46 is opened on the top of the limiting movable card plate 43, and a movable lifting adjustment ring 48 is arranged above the sampling and collection box cover 2. Two plug plates 47 are fixedly connected to the bottom of the movable lifting adjustment ring 48. Two fixing columns 49 are fixedly connected to the top of the cover 2, and the fixing columns 49 pass through the movable lifting adjustment ring 48. A tension spring 51 is sleeved on the outside of the fixing columns 49. The two ends of the tension spring 51 are fixedly connected to the sampling and collection box cover 2 and the movable lifting adjustment ring 48 respectively. Two third support plates 52 are fixedly connected to the inner wall of the movable lifting adjustment ring 48. A second fixing disk 50 is fixedly connected to the top of the fixing columns 49.

[0045] By driving the movable lifting adjustment ring 48 upward, the tension spring 51 is in a stretched state, so that the bottom end of the plug plate 47 is disengaged from the slot 46, and the limit on the position of the limit movable card plate 43 is released. At the same time, the movable plate 54 and the baffle plate 55 move upward, and the bottom horizontal position of the baffle plate 55 is at the same horizontal position as the top horizontal position of the second fixed plate 50. By driving the movable plate 54 and the baffle plate 55 to move, the baffle plate 55 moves to the top of the second fixed plate 50 and is supported by the baffle plate 55 to avoid the movable lifting adjustment. The ring 48 moves downward relative to the fixed column 49, so that the movable lifting adjustment ring 48 and the plug plate 47 maintain the height at this time. The design of the anti-slip plate 53 prevents the third support plate 52 from being separated from the fourth rectangular hole 56, thereby driving the limiting movable card plate 43 to move, so that one end of the limiting movable card plate 43 is separated from the card slot 42, and the fixing relationship between the second limiting plate 41 and the second support plate 39 can be released, so that the second support plate 39 can move upward relative to the second limiting plate 41, thereby driving the sampling collection box cover 2 to move upward, so that the second support The plate 39 moves upward along with the cover 2 of the sampling and collecting box, thereby making the second limiting plate 41 detach from the second rectangular hole 40, and the cover 2 of the sampling and collecting box can be removed, which is convenient for cleaning the inside of the additive sampling and collecting box body 1. When the cover 2 of the sampling and collecting box needs to be installed, the cover 2 of the sampling and collecting box is driven to move to the top of the additive sampling and collecting box body 1, and the second limiting plate 41 passes through the second rectangular hole 40, thereby making the card slot 42 move to one side of the limiting movable card plate 43, and by driving the limiting movable card plate 43 to move, One end of the limiting movable card plate 43 is inserted into the card slot 42, so that the second limiting plate 41 is fixed relative to the second support plate 39, and the slot 46 is moved to just below the plug plate 47, thereby driving the baffle plate 55 and the movable plate 54 to move, so that the baffle plate 55 is no longer in contact with the top of the second fixed plate 50, and the support for the movable lifting adjustment ring 48 is released, and then the tension spring 51 drives the movable lifting adjustment ring 48 to move downward, so that the bottom end of the plug plate 47 is inserted into the slot 46, and the position of the limiting movable card plate 43 can be limited.

[0049] When there is no need to rotate the rotation limiting gear 16, the connecting movable plate 19 is driven to move again, so that the positioning anti-rotation tooth plate 18 and the rotation limiting gear 16 are meshed, and then the rotation adjusting plate 21 is manually driven to rotate, so that the first limiting plate 22 moves to the side of the positioning anti-rotation tooth plate 18 away from the rotation limiting gear 16, and the position of the positioning anti-rotation tooth plate 18 is limited by the first limiting plate 22 to prevent the positioning anti-rotation tooth plate 18 from moving away from the rotation limiting gear 16, so as to limit the position of the rotation limiting gear 16 and the threaded adjustment rotation column 13, and prevent the threaded adjustment rotation column 13 from rotating due to non-human factors;
