Description

Technical Field

[0001] The utility model relates to the field of crushers, in particular to a new type of sealing dust cover for crushers. Background Art

[0002] Crusher is a common ore crushing equipment. When crushing ore, the feed port of the crusher will generate a lot of dust. As the crusher works, the dust will float in the air, which will harm the working environment and the health of operators. Since the feed port needs to continuously feed the crusher, it cannot be sealed. In order to solve the dust prevention effect of the crusher feed port, the dust is currently extracted by an exhaust fan. However, the exhaust fan can only extract the dust at the feed port, and dust will still form at the outlet of the exhaust fan, causing the fine dust to continue to float in the air. Utility Model Content

[0018] like Figures 1 to 4As shown, a new type of sealed dust cover for a crusher includes a dust cover 4 for dustproofing the feed port of the crusher 1. The dust cover 4 is arranged at the feed port of the crusher 1 to reduce the dust generated by the crusher 1 when crushing materials. A motor 6 is arranged on the top of the dust cover 4, and a control switch for controlling the motor 6 is arranged on the side of the crusher 1. The output shaft of the motor 6 extends to the inside of the dust cover 4 and is connected to a rotating rod 11. The rotating rod 11 is provided with a fan blade 12 driven by the power supply machine 6. The end of the rotating rod 11 is provided with a mounting box 13 that rotates synchronously with the rotating rod 11. The mounting box 13 is detachably connected to the end of the rotating rod 11. The bottom is provided with a water inlet hole connected to the inside, and a threaded sealing cover is installed on the water inlet hole. The peripheral surface of the installation box 13 is provided with a plurality of connection holes connected to the inside. The end of the connection rope 14 passes through the connection hole and is fixed to the inside of the installation box 13. The peripheral surface of the installation box 13 is provided with a water-soaked connection rope 14. The water-soaked connection rope 14 can effectively adsorb dust, and the water thrown out by the connection rope 14 during the rotation process of the rotating rod 11 will form a water curtain mixed with dust, thereby further playing a dust-proof effect. The connection rope 14 is used to absorb dust carried by the fan blades 12 during the exhaust process. The top of the dust cover 4 is provided with a vent 5 for ventilation. A sponge for absorbing dust is pasted on the top surface of the dust cover 4, and the sponge covers the vent 5. The sponge can further adsorb dust. The fixed block 2 is threadedly connected to the crusher 1, and the side of the crusher 1 and the support rod 3 are correspondingly provided with fixing holes, and the fixed block 2 is threadedly connected to the fixing holes.

[0019] like Figure 4 As shown, a connecting tube 15 is provided at the connecting hole to prevent the connecting ropes 14 from being entangled with each other. The connecting ropes 14 pass through the connecting tube 15 , and the connecting tube 15 can effectively prevent the roots of the connecting ropes 14 from being entangled with each other.

[0020] A fixing block 2 is provided on the side wall of the feed port of the crusher 1, and a support rod 3 for supporting the dust cover 4 is fixedly connected to the fixing block 2. A rotating hole is provided on the support rod 3. Both sides of the dust cover 4 are provided with rotating shafts rotatably connected in the rotating holes. A fixedly connected rotating disk 7 is provided on the other end of the rotating shaft. The angle of the dust cover 4 can be changed by adjusting the position of the rotating disk 7. A positioning block 8 is correspondingly provided on the support rod 3. Positioning holes 9 are correspondingly provided on the positioning block 8 and the rotating disk 7. A positioning pin 10 for fixing the rotating disk 7 is installed in the positioning hole 9. When adjusting the position of the dust cover 4, the positioning pin 10 is removed. After the adjustment is completed, the positioning pin 10 is inserted into the positioning hole to fix the rotating disk 7.

[0021] The method of using the utility model is briefly described as follows:

[0022] When feeding the crusher 1, turn on the control switch of the motor 6. During the operation of the motor 6, the output shaft of the motor 6 drives the rotating rod 11 to rotate. During the rotation of the rotating rod 11, the fan blades 12 are driven to rotate. The fan blades 12 play a role of suction, and the gas is discharged from the vent hole 5 at the top of the dust cover 4. During the rotation of the rotating rod 11, not only the fan blades 12 are used for adsorption, but also the installation box 13 at the bottom of the rotating rod 11 drives the connecting rope 14 to rotate together. During the rotation of the connecting rope 14, the small stones splashed out from the crusher 1 will be blocked to prevent them from damaging the fan blades 12. During the rotation of the connecting rope 14, the dust can also be adsorbed. The connecting rope 14 can absorb the water in the installation box 13, so that the water is thrown out from the connecting rope 14 to form a water curtain to play a role in dust reduction. When the angle of the dust cover 4 needs to be adjusted, the adjustment can be completed by rotating the rotating disk 7. After the adjustment is completed, the positioning pin 10 can be reinserted into the positioning hole 9.
