Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen device with a dust reduction structure. Background Art

[0002] In the production process of compound fertilizer granules, the role of the vibrating screen is to screen and grade the compound fertilizer granules to ensure that the product meets the specified particle size requirements.

[0003] At present, an existing linear vibrating screen (such as patent number: CN220738460U) discloses a linear vibrating screen, including a linear vibrating screen and a dustproof component, wherein the dustproof component includes a dust cover movably mounted on the top of the linear vibrating screen. The utility model discloses a linear vibrating screen, a dust cover mounted on the top of the linear vibrating screen, and a dust cover arranged on one side of the dust cover, which can prevent dust from the top of the linear vibrating screen during use and filter and collect dust at the discharge port through the exhaust fan and dust storage box installed at the outer end of the dust cover, thereby improving the dustproof effect of the linear vibrating screen during use, so as to avoid the problem of dust flying at the outer end of the linear vibrating screen due to more dust in the material. At the same time, the dust shielding plate installed at the inner end of the discharge port on one side of the dust cover can also block dust at the discharge port, so that both sides of the linear vibrating screen have good dustproof effects, and the inclination angle of the dust shielding plate can also be flexibly adjusted through the screw fixedly connected to the outside, thereby avoiding the problem of affecting the material discharge.

[0004] However, during the implementation of the above technical solution, at least the following problems were found: the dust shield can be adjusted according to the size of the material, but during use, if some of the material poured into the discharge port becomes damp and sticks, the volume of the material increases and the material is blocked by the dust shield and cannot be discharged. If the staff does not clean the damp material at the dust shield in time, the damp material will block the dust shield and affect the discharge of the material, thereby affecting the screening efficiency.

One end is arranged on the outside of the rotating shaft 4, and the two ends of the torsion spring 7 are respectively placed on the outside of the mounting plate 8 and the feed pipe 3.

[0027] By setting the dust shield 5 and cooperating with the torsion spring 7, when the staff pours the material into the feed pipe 3, the material pushes the dust shield 5 to rotate downward when the material falls. At this time, the material slides off the surface of the dust shield 5. When the material falls into the feed pipe 3, the dust shield 5 returns to its original position under the action of the torsion spring 7. At this time, the feed pipe 3 is closed to prevent dust and other fine particles from flying out, thereby playing a dust reduction role. At the same time, the feed port opened by the dust shield 5 is large and will not be blocked by the material, thereby avoiding affecting the screening efficiency.

[0028] Baffles 10 are provided at both ends of the feed pipe 3. Through holes 11 are provided at both ends of the feed pipe 3. The baffles 10 are slidably connected inside the through holes 11 to limit the downward rotation of the dust baffle 5. Fixed blocks 12 are slidably connected at both ends of the feed pipe 3. Two fixed grooves 13 are provided on the outside of each baffle 10. The fixed blocks 12 are slidably connected inside the fixed grooves 13 to fix the baffles 10. Slide grooves 14 are provided at both ends of the feed pipe 3. A threaded groove 15 is provided on one side of the feed pipe 3 close to each slide groove 14.

The fixed block 12 is slidably connected to the interior of the slide groove 14, and the limit screw 16 fits with the fixed block 12, which is convenient for fixing the fixed block 12. By setting the baffle 10, the fixed block 12 is matched. When the vibrating screen is not in use, the limit screw 16 is rotated so that the limit screw 16 is no longer fitted with the fixed block 12. At this time, the fixed block 12 is pulled to release the connection between the fixed block 12 and the fixed groove 13. At this time, the baffle 10 is pushed to make the baffle 10 The dust shield 5 is located on the lower surface of the dust shield 5. At this time, the fixing block 12 is inserted into the inside of another fixing groove 13. At this time, the limit screw 16 is turned to make the limit screw 16 fit the outside of the fixing block 12. At this time, the fixing block 12 is fixed. At this time, the dust shield 5 cannot be rotated downward. At this time, the dust shield 5 closes the feed pipe 3 to prevent dust and debris from entering the interior of the equipment, which is convenient for daily maintenance and cleaning of the equipment. By setting the baffle 10 and cooperating with the fixing block 12, when the vibrating screen is not in use, the limit screw 16 is turned so that the limit screw 16 is no longer in contact with the fixing block 12. The fixed block 12 is fitted, and the fixed block 12 is pulled to release the connection between the fixed block 12 and the fixed groove 13. The baffle 10 is pushed so that the baffle 10 is located on the lower surface of the dust shield 5. The fixed block 12 enters the inside of another fixed groove 13. The limit screw 16 is turned to fit the limit screw 16 to the outside of the fixed block 12. The fixed block 12 is fixed, and the dust shield 5 cannot be rotated downward. The dust shield 5 closes the feed pipe 3 to prevent dust and debris from entering the interior of the equipment, which is convenient for daily maintenance and cleaning of the equipment.

[0029] A slot 17 is provided at both ends of each rotating shaft 4, and the connecting shaft 9 is clamped in the inside of the slot 17 to facilitate the disassembly and assembly of the rotating shaft 4. Threaded rods 18 are fixedly installed at both ends of the feeding pipe 3, and the outside of each threaded rod 18 is slidably connected to a limiting plate 19, and the outside of each threaded rod 18 is threadedly connected to a threaded cap 20. The limiting plate 19 is slidably connected to the end of the connecting shaft 9 away from the slot 17 to facilitate the disassembly and assembly of the connecting shaft 9.

[0030] Working principle:

[0031] In the first step, by setting the dust shield plate 5 and cooperating with the torsion spring 7, when the staff pours the material into the feed pipe 3, the material pushes the dust shield plate 5 to rotate downward when the material falls. At this time, the material slides off the surface of the dust shield plate 5. When the material falls into the feed pipe 3, the rotating plate returns to its original position under the action of the torsion spring 7. At this time, the feed pipe 3 is closed to prevent dust and other fine particles from flying out, thereby playing a role in dust reduction. At the same time, the feed port opened by the dust shield plate 5 is large and will not be blocked by the material, thereby avoiding affecting the screening efficiency.

[0032] The second step is to set the baffle 10 and cooperate with the fixed block 12. When the vibrating screen is not in use, the limit screw 16 is turned so that the limit screw 16 is no longer in contact with the fixed block 12. The fixed block 12 is pulled to release the connection between the fixed block 12 and the fixed groove 13. The baffle 10 is pushed so that the baffle 10 is located on the lower surface of the dust shield 5. The fixed block 12 is inserted into another fixed groove 13. The limit screw 16 is turned so that the limit screw 16 is in contact with the outside of the fixed block 12. The fixed block 12 is fixed. The dust shield 5 cannot be rotated downward. The dust shield 5 closes the feed pipe 3 to prevent dust and debris from entering the equipment, which is convenient for daily maintenance and cleaning of the equipment.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
