[0023] Example: Reference Figure 1-6 The PVC sheet crushing device shown includes a crusher body 1. A dust collecting mechanism is provided above the feed port of the crusher body 1. When the crusher body 1 is working, the dust generated by the processing is collected by the dust collecting mechanism; and a movable mechanism is provided on the top surface of the crusher body 1 to control the extension and retraction of the dust collecting mechanism.

[0024] Dust collecting mechanism: A dust collecting inner groove 31 is provided on the bottom surface of the dust collecting hood 3, and a U-shaped groove is provided on the front and rear inner bottom of the dust collecting inner groove 31. The U-shaped groove is used for installing and removing the filter 9. Limiting bars 8 are provided on the bottom of the left and right inner walls of the dust collecting inner groove 31. The filter 9 is slidably connected to the limiting bars 8, and in order to prevent the limiting bars 8 from falling off from the U-shaped groove on the rear side, a guard plate 5 is provided on the rear end surface of the dust collecting hood 3. The guard plate 5 is used to limit the position of the filter 9; two groups of clamping blocks 91 are provided at the outward end of the filter 9, and bolts are threadedly connected to the outer wall of the dust collecting hood 3, and a clamping block is rotatably connected to the bolt. Part 10, a slot 101 is provided at the free end of the card member 10, and the position of the slot 101 corresponds to the position of the block 91. After the slot 101 of the card member 10 is overlapped with the block 91, the card member 10 is fixed by rotating the bolt to fix the filter 9; a casing is provided in the middle of the top of the dust collecting hood 3, and an air passage is provided on the top of the casing. The casing is transparent from top to bottom (the bottom of the casing is connected to the dust collecting inner groove 31 of the dust collecting hood 3), and a fan 13 is provided inside the casing. An impeller 12 is provided on the driving shaft of the fan 13 to guide and collect the dust generated by the processing of the crusher body 1.

[0025] Moving mechanism: Two sets of guide rails 2 are provided on the top surface of the crusher body 1, and a slide groove 21 is provided on the top surface of the guide rail 2, and a slide rail 4 is provided at the bottom of the dust collecting hood 3 which is slidably connected to the slide groove 21. The slide rail 4 is a trapezoidal structure (and is adapted to the slide groove 21), and a connecting plate 6 is provided at the end of the slide rail 4 to connect the two sets of slide rails 4, and a wedge-shaped reinforcement block 7 is provided between the connecting plate 6 and the slide rail 4 (the connection method of the reinforcement block 7 is welding), and a threaded hole is provided in the middle of the connecting plate 6.

[0026] The working principle of this utility model is as follows: the plate is put into the feed port of the crusher body 1, and before the input, the moving motor is started first. The moving motor drives the moving rod 11 on the driving shaft, and the rotating moving rod 11 is connected to the connecting plate 6 through the threaded connection, so that the connecting plate 6 moves outward, and the connecting plate 6 drives the slide rail 4 connected thereto to slide in the slide groove 21 of the guide rail 2 (the reinforcing block 7 is provided between the connecting plate 6 and the slide rail 4, the purpose of which is to enhance the structural strength), so that the dust collecting hood 3 at the end of the slide rail 4 is located above the feed port, and then the fan 13 inside the casing is started, and the fan 13 drives the impeller 12 to rotate, and the dust generated during crushing is collected through the dust collecting inner groove 31 at the bottom of the dust collecting hood 3, and the filter screen 9 separates the dust particles and gas. Under the action of the impeller 12 and the fan 13, the gas leaves from the air outlet channel, avoiding pollution of the staff's office environment;

[0027] After completing the dust collection task, release the limit on the card 10 by rotating the bolt, and move the card 10 to separate the slot 101 from the block 91 on the filter 9. After releasing the limit, remove the filter 9 from the limit bar 8 for cleaning and maintenance, and put it back in place after completion (the function of the guard plate 5 is to limit the installation of the filter 9).
