[0036] Embodiment 1: Figure 1-Figure 8As shown, a dust suppression component 7 is provided. When the coal mine is fed, the motor 72 is started, and the motor 72 drives the gear 73 to rotate. The gear 73 drives the gear ring 75 and the fan blades 76 to rotate. The fan blades 76 exhaust air from the lower box body 74, and pass through the connecting pipe 77 and the upper box body 78, and then through the air holes on the connecting rod 712, and finally through the dust extraction cylinder 713. The dust extraction cylinder 713 is located on the outer ring of the feeding pipe 3, which is convenient for extracting dust during feeding. At the same time, the water pump 10 pumps water from the water tank 9, so that the water flows into the mounting ring 717 through the water pipe 11, and then flows into the connecting pipe 718 from the mounting ring 717, and finally sprays it out from the nozzle 719 in the form of mist, which is convenient for further spraying and dust reduction.

[0037] When there is a lot of dust in the fed coal mine, the range of dust dissipation is also large. Keep the slide bar 79 stationary, pull the dust extraction tube 713 to drive the connecting rod 712 to move outward, the connecting rod 712 drives the stopper 715 to slide in the slide groove 714, the connecting rod 712 drives the sleeve 711 to move, the sleeve 711 compresses the limit plate 725, and the limit plate 725 squeezes the spring 2 726. When the sleeve 711 moves to the side of the limit plate 725 close to the spring 2 726, the elastic force of the spring 2 726 drives the limit plate 725 to bounce open, which makes it easier to block the sleeve 711.

When the sliding sleeve 711 needs to be reset, the turntable 710 is rotated ninety degrees to make the give way groove 723 correspond to the limit plate 725. At this time, the sliding sleeve 711 slides and resets. By moving the position of the dust extraction cylinder 713, the extraction range can be adjusted to adapt to the situation with more dust. This solves the problem that the device only removes dust by exhausting air through the exhaust fan, and the exhaust position is fixed, so that the exhaust effect is relatively general. When dealing with mineral materials containing a lot of dust, dust may still escape, reducing the dustproof effect of the device.

[0039] An installation assembly 8 is provided inside the vibration screen body 1, and the installation assembly 8 includes an auxiliary plate 81, a screen plate 82 and a positioning bar 83.

[0042] Embodiment 2: Figure 9-11 As shown, an installation component 8 is provided. When the screen plate 82 needs to be installed, the screen plate 82 is placed on the top of the auxiliary plate 81 and the positioning strip 83, so that the fixing rod 84 passes through the screen plate 82 and the rotating member 85, and then the rotating member 85 is screwed. The rotating member 85 drives the clamping block 87 to rotate, so that the position of the clamping block 87 corresponds to the arc groove 89. At this time, the elastic force of the spring three 88 drives the clamping block 87 to pop out, so that the clamping block 87 is convenient for being stuck in the arc groove 89. Through the multiple rotating members 85 and the fixing rod 84, the screen plate 82 is conveniently pressed and limited, thereby improving the convenience of installation.

[0043] Working principle: When using the device, first, Figure 1-Figure 11 As shown, when feeding the coal mine, the motor 72 is started, the motor 72 drives the gear 73 to rotate, the gear 73 drives the gear ring 75 and the fan blades 76 to rotate, the fan blades 76 exhaust air from the lower box 74, and pass through the connecting pipe 77 and the upper box 78, and then through the air holes on the connecting rod 712, and finally through the dust extraction cylinder 713. The dust extraction cylinder 713 is located on the outer ring of the feeding pipe 3, which is convenient for extracting dust during feeding. At the same time, the water pump 10 pumps water from the water tank 9, so that the water flows into the mounting ring 717 through the water pipe 11, and then flows into the connecting pipe 718 from the mounting ring 717, and finally sprays out from the nozzle 719 in a mist form, which is convenient for further spraying and dust reduction.

[0044] When there is a lot of dust in the fed coal mine, the range of dust dissipation is also large. Keep the slide bar 79 stationary, pull the dust extraction tube 713 to drive the connecting rod 712 to move outward, the connecting rod 712 drives the stopper 715 to slide in the slide groove 714, the connecting rod 712 drives the sleeve 711 to move, the sleeve 711 compresses the limit plate 725, and the limit plate 725 squeezes the spring 2 726. When the sleeve 711 moves to the side of the limit plate 725 close to the spring 2 726, the elastic force of the spring 2 726 drives the limit plate 725 to bounce open, which makes it easier to block the sleeve 711. The limit block 727 is used to limit the rotation angle of the card block 728 and the limit plate 725.

[0045] The dust extraction cylinder 713 moves and pulls the connecting strip 721, and the connecting strip 721 pulls the telescopic rod 722. When the auxiliary spring in the telescopic rod 722 is stretched to the maximum, the nozzle 719 rotates a certain angle, and the nozzle 719 stretches the spring 720, thereby increasing the spray pipe range of the nozzle 719 to adapt to the situation with more dust. When the sleeve 711 needs to be reset, the turntable 710 is rotated ninety degrees to make the clearance groove 723 correspond to the limit plate 725. At this time, the sleeve 711 slides and resets. By moving the position of the dust extraction cylinder 713, the extraction range can be adjusted to adapt to the situation with more dust.

[0046] When the screen plate 82 needs to be installed, the screen plate 82 is placed on the top of the auxiliary plate 81 and the positioning strip 83, so that the fixing rod 84 passes through the screen plate 82 and the rotating member 85, and then the rotating member 85 is screwed. The rotating member 85 drives the clamping block 87 to rotate, so that the clamping block 87 corresponds to the position of the arc groove 89. At this time, the elastic force of the spring three 88 drives the clamping block 87 to pop out, so that the clamping block 87 is convenient for being stuck in the arc groove 89. Through the multiple rotating members 85 and the fixing rod 84, the screen plate 82 is conveniently pressed and limited, thereby improving the convenience of installation.
