Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a dustproof vibrating screen. Background Technology

[0002] Vibrating screens operate by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two factors results in a complex rotary vibration of the screen surface. Since vibrating screens generate dust during material screening, a dustproof vibrating screen is required.

[0003] When operators are screening materials, they often use corresponding vibrating screens. Although existing vibrating screens can achieve the purpose of screening, they will generate dust during actual use. If the dust is not treated, it may harm the health of the operators. In addition, large vibrating screens have large vibration amplitudes and heavy screen bodies, and strong dynamic loads during operation. It is difficult to ensure stability by relying solely on their own conventional support legs, resulting in poor stability. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof vibrating screen to solve the problem mentioned in the background art. When operators are screening materials, they often use corresponding vibrating screens. Although existing vibrating screens can achieve the purpose of screening, they will generate dust in actual use. If the dust is not treated, it may harm the health of the operators. In addition, large vibrating screens have large vibration amplitude and heavy screen body when working. The dynamic load during operation is strong, and it is difficult to ensure stability by relying solely on its own conventional support legs. The stability is not good.

A filter bag is fixedly installed between the mounting plate and the movable plate. The top of the filter bag passes through the movable plate and extends to the top of the movable plate. The bottom of the filter bag passes through the mounting plate and extends to the bottom of the mounting plate. A rotating shaft is rotatably installed between the dust boxes. Rotating rods are fixedly sleeved on both sides of the rotating shaft. Adjusting rods are hinged between the rotating rods and the movable plate. An adjusting motor is fixedly installed on one side of the dust box. The output end of the adjusting motor passes through the dust box and is fixedly connected to one side of the rotating shaft. A vibrating screen body is fixedly installed on the top of the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This dustproof vibrating screen works as follows: During daily use, the operator starts the fan, which draws air through the suction pipe. Dust generated during material screening enters the dustproof chamber through the suction pipe. The dust then flows with the air and adheres to the inner surface of the filter bags. The air is eventually discharged through the exhaust pipe. At this point, the regulating motor is activated, causing the rotating shaft to rotate. This shaft then drives the rotating rod, which in turn drives the regulating rod. Simultaneously, the regulating rod causes the movable plate to slide, which in turn causes the filter bags to slide. The movable plate then compresses the springs, increasing the vibration of the filter bags and shaking the dust from the filter bags to the bottom of the dustproof chamber, thus treating the dust and achieving dust prevention.

[0013] In daily use, this dustproof vibrating screen allows operators to move the base plate and the top of the vibrating screen body via the casters. Rotating the throttle causes the lead screw to rotate, which in turn drives the sliding sleeve to slide inside the slot. This sliding sleeve then drives the lifting plate to slide, which in turn drives the round rod to slide inside the base plate. The round rod then drives the support plate to slide until the bottom of the support plate is placed on the ground, thus providing auxiliary support for the base plate and the vibrating screen body, thereby increasing its stability.

A lead screw 21 is rotatably installed inside each strip groove 20, and a sliding sleeve 22 is threaded onto the surface of each lead screw 21. When the lead screw 21 rotates, it causes the sliding sleeve 22 to slide inside the strip groove 20. A handle 23 is rotatably installed on the top of each vertical plate 19, and the bottom of the handle 23 passes through the vertical plate 19 and is fixedly connected to the top of the lead screw 21. Rotating the handle 23 causes the lead screw 21 to rotate. A lifting plate 24 is fixedly installed on one side of each sliding sleeve 22.

The sliding sleeve 22 then drives the lifting plate 24 to slide, and the lifting plate 24 simultaneously drives the round rod 25 to slide inside the base plate 1. The round rod 25 then drives the support plate 26 to slide until the bottom of the support plate 26 is on the ground, thus providing auxiliary support for the base plate 1 and the vibrating screen body 13. Next, the blower 14 is started. The operation of the blower 14 draws air through the suction pipe 15, and the dust generated by the vibrating screen body 13 during material screening enters the dust box 2 through the dust suction pipe 3. Inside, dust will flow with the gas and adhere to the inner surface of the filter bag 8. The gas will eventually be discharged through the exhaust pipe 16. At this time, the regulating motor 12 is started. The operation of the regulating motor 12 will cause the rotating shaft 9 to rotate. The rotating shaft 9 will then drive the rotating rod 10 to rotate. The rotating rod 10 will then drive the regulating rod 11 to rotate. At the same time, the regulating rod 11 will drive the movable plate 6 to slide. The movable plate 6 will then drive the filter bag 8 to slide. The movable plate 6 will then compress the spring 5 and increase the vibration of the filter bag 8, which will shake the dust in the filter bag 8 to the bottom of the dust box 2. Then, by pulling the movable door 17 with the handle 18 to open the dust box 2, the dust at the bottom of the interior can be cleaned. Conversely, it can be reset.
