The output end of the motor is fixedly connected to the right end of the first crushing roller 913, and the first gear 915 meshes with the second gear 916.

[0032] The scraping component 92 includes a fixing frame 921, the fixing frame 921 is fixedly connected to the left side of the top of the box body 3, a screw rod 922 is rotatably connected to the left side of the top of the box body 3, a second motor 923 is fixedly connected to the top of the fixing frame 921, a T-shaped plate 924 is threadedly connected to the surface of the screw rod 922, two limiting rods 925 are fixedly connected to the front and rear sides of the inner top of the fixing frame 921, two sliding blocks 926 are fixedly connected to the front and rear ends of the bottom of the T-shaped plate 924, and a scraping plate 927 is fixedly connected to the bottom end of the sliding block 926.

[0033] The output end of the second motor 923 is fixedly connected to the top end of the screw rod 922, the bottom end of the limiting rod 925 is fixedly connected to the left side of the top of the box body 3, through holes matching the limiting rods 925 are formed in the front and rear sides of the top of the T-shaped plate 924, and the T-shaped plate 924 is slidably connected to the surface of the limiting rod 925 through the through holes. The limiting rod 925 limits the T-shaped plate 924, so that the T-shaped plate 924 moves up and down as the screw rod 922 rotates. Through slots matching the sliding blocks 926 are formed in the front and rear of the left side of the top of the box body 3, and the surface of the sliding block 926 penetrates and is slidably connected in the through slots. Through holes matching the connecting air pipe 813 are formed in the top of the scraping plate 927, and the scraping plate 927 is slidably connected to the surface of the connecting air pipe 813 through the through holes.

[0034] In the actual operation process, when this device is in use, the material enters the box body 3 through the feeding cylinder 4 at the top of the box body 3. After being crushed in the box body 3, it is discharged from the discharge hole 6 at the bottom left of the box body 3 and slides down along the guiding plate 7 into the material collection box 2 on the top left of the base 1 for collection. Since universal wheels 32 are installed at the lower ends of the supporting legs 31 at the bottom of the box body 3, the entire dust-removing crushing table can move flexibly, facilitating the adjustment of the working position. The motor of the crushing mechanism is fixed on the right side of the L-shaped seat 911, and the L-shaped seat 911 is connected to the position near the front on the right side of the box body 3. After the motor is started, its output end drives the first crushing roller 913 to rotate. The first gear 915 near the right end on the surface of the first crushing roller 913 meshes with the second gear 916 near the right end on the surface of the second crushing roller 914, so that the second crushing roller 914 rotates in the opposite direction following the first crushing roller 913. After the material enters the box body 3, it is crushed into smaller particles under the actions of extrusion, shearing, etc. between the first crushing roller 913 and the second crushing roller 914 rotating towards each other. The dust suction pump 811 of the dust suction assembly 81 is fixed on the top right of the box body 3, and its air inlet end is communicated with the inside of the box body 3 through the air inlet pipe 812. The other end of the air inlet pipe 812 is connected to the left side of the inner wall of the box body 3, and a connecting air pipe 813 with a blocking net is also connected to the surface of the air inlet pipe 812. When the dust suction pump 811 works, a negative pressure is formed in the box body 3, and the dust-containing air is sucked in from the air inlet pipe 812 and the connecting air pipe 813. The blocking net can initially intercept larger-particle dust. The air outlet pipe 814 connected to the air outlet end of the dust suction pump 811 discharges the dust-containing air into the collection box 815 near the bottom on the right side of the box body 3. A filter screen 816 is provided near the bottom on the front of the collection box 815. After the air passes through the filter screen 816 for filtration, the clean air is discharged from the exhaust hole 817 near the back on the top right of the box body 3, while the dust is intercepted in the filter screen 816 and the collection box 818. When it is necessary to process the dust in the filter screen 816 and the collection box 818, pull the connecting plate 824. The movement of the connecting plate 824 will drive the sliding rod 823 and the pressing plate 825 to move forward, and the forward movement of the pressing plate 825 will compress the spring 826. Then rotate the rotating plate 822 and the rotating rod 821 to make the pressing plate 825 move away from the front of the filter screen 816 and the collection box 818. Then draw out the old filter screen 816 from the collection box 815, slide the new filter screen 816 into the box body 3, then draw out the collection box 818 from the collection box 818 to process the dust in the collection box 818. Then slide the collection box 818 after processing the dust into the box body 3. Then rotate the rotating plate 822 and the rotating rod 821 in the reverse direction to make the pressing plate 825 rotate to the front of the filter screen 816 and the collection box 818. Then release the connecting plate 824. At this time, the pressing plate 825 will move backward through the elastic force of the spring 826 to press the filter screen 816 and the collection box 818. The sliders 926 at the front and rear ends of the bottom of the T-shaped plate 924 match the grooves opened at the front and rear on the top left of the box body 3. As the T-shaped plate 924 moves up and down, the sliders 926 slide in the grooves.Ensure the stable lifting of the T-shaped plate 924. The scraper 927 fixedly connected to the bottom end of the slider 926 will move up and down in the box body 3 as the T-shaped plate 924 lifts. A hole matching the connecting air pipe 813 is provided at the top of the scraper 927, and it can slide up and down along the surface of the connecting air pipe 813. During the material crushing process, when the scraper 927 moves downward, it can scrape off the material adhering to the surface of the connecting air pipe 813, making it fall to the bottom of the box body 3, avoiding material accumulation from affecting the normal operation of the equipment and the crushing effect.
