[0025] Embodiment 1

[0026] Please refer to Figure 1-6 , the present utility model provides a technical solution: an oil and grain impurity detection and extraction device, including a cylinder body 1 and a mounting plate 17. A slide bar 2 is slidably connected to the inner side of the cylinder body 1. A spring A 3 is sleeved on the surface of the slide bar 2. One end of the spring A 3 is fixedly installed at the top end of the cylinder body 1, and the other end of the spring A 3 is fixedly installed on the surface of the slide bar 2. Under the action of the spring A 3, the slide bar 2 and the piston 4 will be driven to rise along the cylinder body 1. At this time, under the action of pressure, the surrounding oil and grain will be sucked in through the holes of the cover plate 9. The bottom end of the slide bar 2 is fixedly installed with a piston 4. When the piston 4 slides downward, it will drive the slide plate 5 to slide, and at the same time, it will also drive the position of the limit groove 6 to change. When the slide plate 5 pushes against the connecting plate 7, at this time, under the action of pressure and the connecting plate 7, the convex block 8 and the cover plate 9 will be driven to rotate, so that the external oil and grain can enter the inner side of the cylinder body 1. The piston 4 is slidably connected to the cylinder body 1. The bottom end of the piston 4 is fixedly installed with a slide plate 5. The slide plate 5 is slidably connected to the cylinder body 1. A limit groove 6 is opened inside the slide plate 5. A connecting plate 7 is arranged inside the limit groove 6. A convex block 8 is rotatably connected to the inside of the connecting plate 7. The convex block 8 is fixedly installed on the back of the cover plate 9. The cover plate 9 is rotatably connected to the inside of the cylinder body 1. The cover plate 9 is slidably connected to the groove plate 10. The groove plate 10 is fixedly installed on the surface of the cylinder body 1. A convex plate 11 is fixedly installed on the surface of the groove plate 10. A placement groove 12 is opened inside the convex plate 11. A spring B 13 is arranged inside the placement groove 12. One end of the spring B 13 is fixedly installed inside the placement groove 12. A limit bead 14 is arranged inside the placement groove 12. The limit bead 14 is in rolling connection with the placement groove 12. A card slot 15 is opened inside the cover plate 9.

[0027] Embodiment 2

[0028] Please refer to Figure 6-7, a limiting plate 16 is fixedly installed on the surface of the cylinder body 1. An arc-shaped groove 18 is provided inside the mounting plate 17. A limiting piece 19 is rotatably connected to the surface of the mounting plate 17. Align the limiting plate 16 with the arc-shaped groove 18 and insert it along the arc-shaped groove 18. Then rotate the limiting piece 19 and make it abut against the surface of the limiting plate 16. At this time, the installation between the cylinder body 1 and the mounting plate 17 is completed. A sliding groove 20 is provided inside the mounting plate 17. A pressing plate 22 is slidably connected inside the sliding groove 20. The pressing plate 22 is fixedly installed at the output end of the air cylinder 23. Start the air cylinder 23. Under the action of the air cylinder 23, it will drive the connecting plate 21 and the pressing plate 22 to slide along the sliding groove 20. Then the pressing plate 22 will press down the sliding rod 2 and drive the piston 4 to slide inside the cylinder body 1. A connecting plate 21 is fixedly installed on the back surface of the pressing plate 22, and an air cylinder 23 is fixedly installed at the top end of the mounting plate 17.

[0029] Working principle: During operation, first align the limiting plate 16 with the arc-shaped groove 18 and insert it along the arc-shaped groove 18. Then rotate the limiting piece 19 and make it abut against the surface of the limiting plate 16. Then insert the mounting plate 17 into the grain and oil and start the air cylinder 23. Under the action of the air cylinder 23, it will drive the connecting plate 21 and the pressing plate 22 to slide along the sliding groove 20. Then the pressing plate 22 will press down the sliding rod 2 and drive the piston 4 to slide inside the cylinder body 1, thereby exhausting the air inside the cylinder body 1. While the piston 4 slides downward, it will drive the sliding plate 5 to slide, and at the same time, it will also drive the position of the limiting groove 6 to change. When the sliding plate 5 pushes against the connecting plate 7, at this time, under the action of the pressure and the connecting plate 7, it will drive the convex block 8 and the cover plate 9 to rotate, so that the external grain and oil can enter the inside of the cylinder body 1. During the rotation of the cover plate 9, it will first contact the convex plate 11 and squeeze the limiting bead 14 and the spring B13. Then, under the action of the spring B13, it will drive the limiting bead 14 to reset inside the card slot 15. Then start the air cylinder 23 and drive the pressing plate 22 to rise. Under the action of the spring A3, it will drive the sliding rod 2 and the piston 4 to rise along the cylinder body 1. At this time, under the action of the pressure, it will suck in the surrounding grain and oil through the holes of the cover plate 9. As the sliding rod 2 rises, it will drive the sliding plate 5 to rise, and at the same time, it will drive the position of the limiting groove 6 to change again. When the sliding plate 5 pushes against the connecting plate 7, at this time, under the action of the pressure and the connecting plate 7, it will drive the convex block 8 and the cover plate 9 to rotate in the opposite direction, and then it can drive the cover plate 9 to be released from the limiting state of the limiting bead 14 and close the cylinder body 1. Then the limiting piece 19 can be rotated and it no longer abuts against the surface of the limiting plate 16, and the limiting plate 16 is pulled out along the arc-shaped groove 18, so that the detection of grain and oil at different depths can be carried out.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
