Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a splash-proof structure for sieving parboiled rice, including a parboiled rice sieving machine 1, a flexible sealing protective cover 7, an inner screw adjusting cylinder 10, a middle adjusting cylinder 12, and a lower adjusting rod 16. A fixed threaded rod 9 is installed at the lower end of the parboiled rice sieving machine 1. A discharge pipe 4 is installed through the lower right side of the parboiled rice sieving machine 1. A stepped ring 5 is bolted to the lower end of the discharge pipe 4. The flexible sealing protective cover 7 is longitudinally arranged at the lower end of the stepped ring 5. A connecting ring 8 is horizontally arranged at the lower end of the flexible sealing protective cover 7. A connecting plate 1 is fixed to the left end of the connecting ring 8. 9. A stepped fixing cylinder 18 is longitudinally installed on the upper end of the connecting plate 19. The inner screw adjusting cylinder 10 is screwed onto the outside of the fixed threaded rod 9. A limit piece 11 is fixed at the lower end of the inner screw adjusting cylinder 10. The upper end of the middle adjusting cylinder 12 is inserted into the inner screw adjusting cylinder 10. A second anti-detachment ring 15 is fixed at the lower end of the middle adjusting cylinder 12. The upper end of the lower adjusting rod 16 is inserted into the middle adjusting cylinder 12. The lower end of the lower adjusting rod 16 is fixed into the stepped fixing cylinder 18. This design solves the problem that the original equipment is prone to splashing of parboiled rice during discharge under the action of vibration and airflow.

[0019] As the first embodiment of this utility model: A feeding hopper 2 and a blower 3 are installed on the upper left side of the parboiled rice screening machine 1. The parboiled rice screening machine 1 is equipped with a vibrator. A magnetic ring 6 is fixed to the upper edge of the stepped ring 5 with epoxy resin. The magnetic ring 6 and the lower end of the discharge pipe 4 are magnetically attracted by a magnet. The stepped ring 5 is fixed to the lower end of the discharge pipe 4 with bolts, which can ensure quick installation and fixation between the stepped ring 5 and the discharge pipe 4.

[0020] The flexible sealing shield 7 is made of silicone. By adding this silicone material, the silicone can be easily folded, bent, and stretched without damage. It has excellent resilience, quickly returning to its original shape even after multiple folds without leaving permanent creases. Due to its superior flexibility and elasticity, silicone is commonly used in applications requiring frequent folding or bending, such as seals, food-grade product packaging, and medical devices.

[0021] A first anti-detachment ring 14 is fixed to the upper edge of the middle adjusting cylinder 12, and a third anti-detachment ring 17 is fixed to the upper edge of the lower adjusting rod 16. The first anti-detachment ring 14 prevents the upper end of the middle adjusting cylinder 12 from detaching from the inner threaded adjusting cylinder 10, and the third anti-detachment ring 17 prevents the lower adjusting rod 16 from detaching from the middle adjusting cylinder 12. Both the front end of the middle adjusting cylinder 12 and the front end of the inner threaded adjusting cylinder 10 are threaded with wing bolts 13. The wing bolts 13 secure the inner threaded adjusting cylinder 10, the middle adjusting cylinder 12, and the lower adjusting rod 16 together.

[0022] As a second embodiment of this utility model: When it is necessary to install this device at the discharge pipe 4 to prevent splashing of the parboiled rice discharged from the screen, the step ring 5 is fastened to the lower end of the discharge pipe 4, so that the magnetic ring 6 and the lower end of the discharge pipe 4 are magnetically attracted by the magnet. Then, the bolts are tightened between the step ring 5 and the discharge pipe 4 to complete the installation of the flexible sealing protective cover 7. Next, the inner screw adjusting cylinder 10 is screwed onto the outside of the fixed threaded rod 9. Then, the two wing bolts 13 are loosened to adjust the insertion depth of the upper end of the middle adjusting cylinder 12 into the inner screw adjusting cylinder 10, and also to adjust the insertion depth of the upper end of the lower adjusting rod 16 into the middle adjusting cylinder 12. In this way, the height can be adjusted by driving the connecting plate 19 through the step fixing cylinder 18. During this process, the flexible sealing protective cover 7 can be extended downward through the connecting ring 8 until the flexible sealing protective cover 7 extends downward to a suitable length. The two wing bolts 13 are tightened again, so that the elongated flexible sealing protective cover 7 can prevent splashing of the parboiled rice discharged from the screen.
