[0021] The technical solutions of this patent will be further described in detail below in combination with the specific embodiments.

[0022] Such as Figures 1-5As shown in the figure, the present utility model provides a technical solution: a screening device for preventing blockage of barium sulfate powder, including a base 1. A collection box 2 is provided at the inner bottom of the base 1. Vibration motors 3 are symmetrically and fixedly installed on both sides of the base 1. A conical sleeve 5 is fixedly installed at the bottom of a fixing plate 4, and the position of the bottom of the conical sleeve 5 corresponds to that of the collection box 2. By providing the conical sleeve 5 and the collection box 2, the barium sulfate powder screened by a sieve cylinder 13 falls into the inside of the conical sleeve 5 and drops into the inside of the collection box 2 from the outlet at the bottom of the conical sleeve 5, ensuring that the barium sulfate powder can be concentrated and fall into the inside of the collection box 2 without spilling.

[0023] A fixing plate 4 is fixedly installed at the top of the base 1. A top plate 9 is provided at the top of the fixing plate 4. A sieve cylinder 13 is provided at the top of the top plate 9. Six groups of positioning sleeves one 6 are fixedly installed at equal angles at the top of the fixing plate 4, and a positioning rod one 7 is fixedly installed at the top of the fixing plate 4 inside the positioning sleeve one 6. Six groups of positioning sleeves two 10 are fixedly installed at equal angles at the bottom of the top plate 9, and a positioning rod two 11 is fixedly installed at the bottom of the top plate 9 inside the positioning sleeve two 10. The positioning sleeve two 10 and the positioning rod two 11 respectively correspond to the positions of the positioning sleeve one 6 and the positioning rod one 7. A vibration spring 8 is fixedly installed inside the fixing plate 4 and the top plate 9 between the positioning sleeve one 6 and the positioning sleeve two 10. Due to the provision of the positioning rod one 7 and the positioning rod two 11, the vibration spring 8 is stuck on the surfaces of the positioning rod one 7 and the positioning rod two 11 inside the positioning sleeve one 6 and the positioning sleeve two 10, and the two ends of the vibration spring 8 will not be displaced and separated from the positioning sleeve one 6 and the positioning sleeve two 10 when rebounding and contracting;

[0024] Multiple groups of positioning posts 12 are fixedly installed at equal angles at the top of the top plate 9, and the positioning posts 12 pass through the sieve cylinder 13. By providing the positioning posts 12, when the sieve cylinder 13 is placed on the top of the top plate 9, the positioning posts 12 can pass through the sieve cylinder 13, thereby restricting the position of the sieve cylinder 13 on the top of the top plate 9 and ensuring that the sieve cylinder 13 will not be relatively deflected due to vibration on the top of the top plate 9.

[0025] An installation column 14 is provided at the central position of the inner bottom of the sieve cylinder 13. A cross groove one 15 is provided at the top of the installation column 14. A cross groove two 22 is provided at the bottom of a rotating column 21. The cross groove one 15 and the cross groove two 22 correspond to the position of a cross insert block 26 and have the same shape. Three groups of cleaning brushes 16 are fixedly installed at equal angles at the bottom of the surface of the installation column 14, and a fixing ring 17 is fixedly installed between the ends of the three groups of cleaning brushes 16 away from the installation column 14. Due to the provision of the cleaning brushes 16 and the fixing ring 17, when controlling the installation column 14 to rotate inside the sieve cylinder 13, the cleaning brushes 16 push the barium sulfate powder to rotate at the inner bottom of the sieve cylinder 13, preventing the barium sulfate powder from blocking the sieve cylinder 13. At the same time, the fixing ring 17 supports and fixes the three groups of cleaning brushes 16, ensuring that the three groups of cleaning brushes 16 will not be relatively deflected under the action of the resistance when pushing the barium sulfate powder.

[0026] A concave frame 18 is fixedly installed on both sides of the top of the fixed plate 4, and a rotating column 21 is rotatably installed on the top of the concave frame 18. A rotating motor 19 is fixedly installed on the top of the concave frame 18 on one side of the rotating column 21, and a bevel gear 20 is fixedly installed on the output end of the rotating motor 19. The top of the rotating column 21 passes through the concave frame 18 and is fixedly installed with a bevel gear 20. The two sets of bevel gears 20 are meshed with each other. By providing a rotating motor 19, starting the rotating motor 19 controls the rotating column 21 to rotate under the meshing action of the two sets of bevel gears 20, thereby driving the connecting column 23 and the mounting column 14 to rotate synchronously.

[0027] A connecting column 23 is provided between the rotating column 21 and the mounting column 14, and a cross mounting groove 24 is symmetrically provided at both ends of the connecting column 23; four groups of limiting slide bars 25 are fixedly installed inside the cross mounting groove 24, and a cross plug block 26 is slidably installed on one end surface of the four groups of limiting slide bars 25, and a clamping spring 27 is provided on the surface of the limiting slide bar 25 located between the cross plug block 26 and the inside of the cross mounting groove 24. Because the limiting slide bar 25 and the clamping spring 27 are provided, when the cross plug block 26 is controlled to slide up and down inside the cross mounting groove 24, the clamping spring 27 is squeezed and rebounded on the surface of the limiting slide bar 25, ensuring that the clamping spring 27 will not be misplaced or offset when being squeezed and rebounded;

[0028] Four groups of slide grooves 28 are respectively provided on the surfaces of both ends of the connecting column 23, and the slide grooves 28 are connected to the cross mounting groove 24. Four groups of connecting protrusions 29 are fixedly installed on the surface of the cross plug 26 close to the limiting slide rod 25, and the four groups of connecting protrusions 29 are fixedly installed with connecting rings 30 passing through the slide grooves 28. By providing the connecting protrusions 29, the connecting rings 30 are pushed to drive the connecting protrusions 29 to slide inside the corresponding slide grooves 28, and when the cross plug 26 is controlled to slide inside the cross mounting groove 24, it is ensured that the cross plug 26 will not fall out of the cross mounting groove 24.

[0029] The working principle of the utility model is:

[0030] After pushing the collection box 2 to move to the inner bottom of the base 1 and positioning it behind the bottom of the conical sleeve 5, the sieve cylinder 13 is correspondingly clamped on the top of the top plate 9. The cleaning brush 16 is placed inside the sieve cylinder 13 to make the positions of the mounting column 14 and the rotating column 21 correspond. Push and squeeze the two connecting rings 30 to move closer to each other, and control the connecting lug 29 to drive the cross-shaped insertion block 26 to retract into the cross-shaped mounting groove 24. The connecting column 23 is clamped between the mounting column 14 and the rotating column 21. After the cross-shaped insertion blocks 26 at both ends of the connecting column 23 respectively correspond to the first cross-shaped groove 15 and the second cross-shaped groove 22, release the connecting ring 30. Under the rebounding action of the clamping spring 27, the cross-shaped insertion block 26 at the top is inserted into the corresponding first cross-shaped groove 15 or the second cross-shaped groove 22. Pour an appropriate amount of barium sulfate powder into the sieve cylinder 13, start the two vibration motors 3 to control the base 1, the top plate 9 and the sieve cylinder 13 to vibrate. At the same time, start the rotating motor 19 to drive the rotating column 21, the connecting column 23 and the mounting column 14 to rotate synchronously, so that the cleaning brush 16 rotates on the inner bottom of the sieve cylinder 13, pushing the barium sulfate powder to move inside the sieve cylinder 13 to prevent the barium sulfate powder from blocking the sieve cylinder 13. The barium sulfate powder after vibration screening falls into the collection box 2 through the conical sleeve 5.
