Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a sheet metal dust hood, including a dust hood body 1, a motor 2 is installed on the left end of the dust hood body 1, a rotating shaft 3 is fixedly connected to the right side of the motor 2, a grinder 4 is fixedly connected to the middle of the rotating shaft 3, gears 5 are fixedly connected to the left and right sides of the rotating shaft 3, a rack 6 is meshed at the front end of the gear 5, movable grooves 7 are opened on the left and right sides of the dust hood body 1, an elastic component for elastic expansion and contraction is arranged in the movable groove 7, a filter screen 11 is fixedly connected between the two groups of racks 6, an adsorption component for adsorbing debris is arranged on the front side of the dust hood body 1, and a dust box 16 is slidably connected to the lower end of the dust hood body 1;

[0021] By providing an elastic component, the device can drive the filter 11 to move up and down while the grinder 4 is processing, thereby shaking the debris that falls on the filter 11 and makes it fall into the dust box 16, and the debris is collected for easy later cleaning. In addition, by providing an adsorption component, the debris during processing can be blocked to prevent it from splashing around, and a portion of the debris with small mass can be adsorbed for preliminary collection of the debris.

[0022] Furthermore, half of the outer wall of the gear 5 is provided with teeth, and the teeth of the gear 5 are adapted to the tooth grooves of the rack 6, such as Figure 3 As shown, this structure enables the gear 5 to push the rack 6 to move when it is meshed with the rack 6, and the rack 6 to move in the opposite direction to restore the original position when the gear 5 is not meshed with the rack 6.

[0023] Further, the elastic component includes a vertical rod 8, the front end bottom of the movable groove 7 is fixedly connected to the vertical rod 8, a spring 9 is sleeved on the vertical rod 8, the lower end of the spring 9 is fixedly connected to the inner wall of the movable groove 7, the upper end of the spring 9 is fixedly connected to a slider 10, and the rear side of the slider 10 is fixedly connected to the rack 6, such as Figure 3 and Figure 4As shown, the structure can drive the filter screen 11 to move up and down through the expansion and contraction of the spring 9, thereby achieving a shaking effect.

[0024] Further, the adsorption assembly includes a bidirectional screw 12, the front side of the dust collecting cover body 1 is rotatably mounted with the bidirectional screw 12, the bidirectional screw 12 is threadedly connected with a screw sleeve 13, one side of the screw sleeve 13 is fixedly connected with a baffle 14, and the right end of the bidirectional screw 12 is fixedly connected with a knob 15, such as Figure 2 As shown, the structure can adjust the distance between the two sets of baffles 14 according to the size of the processed parts, and can block the chips during processing to prevent them from splashing around.

[0025] Furthermore, the two sets of baffles 14 are arc-shaped with openings facing each other, and magnets are disposed on the inner walls of the baffles 14. Figure 2 As shown, the structure absorbs small debris that is not easy to fall off.

[0026] Furthermore, water is stored in the dust box 16, and the outer diameter of the dust box 16 is adapted to the inner diameter of the dust cover body 1. Figure 2 As shown, this structure makes it difficult for the debris dropped into the dust box 16 to fly up again, thus preventing the processing environment from being polluted.

[0027] Working principle: first, place the processed parts on the filter 11, located at the front end of the grinder 4, and fix it, then turn the knob 15, so that the knob 15 drives the bidirectional screw 12 to rotate and perform threading action with the screw sleeve 13, and the screw sleeve 13 drives the baffle 14 to move to the middle at the same time. When the two sets of baffles 14 move close to the parts and leave a certain amount of movable space, stop rotating the knob 15, and then start the motor 2, so that the motor 2 drives the shaft 3 and the grinder 4 to rotate. The grinder 4 processes the parts while rotating, and the small-mass debris generated by the processing is absorbed by the baffle 14, and the large-mass debris falls on the filter 11. At the same time, the two sets of gears 5 rotate together, and the gear 5 rotates while pushing the rack 6 moves, and the rack 6 moves while driving the slider 10 to slide on the vertical rod 8 and compressing the spring 9. When the gear 5 rotates to the side without teeth and fits with the rack 6, the rack 6 is no longer pushed by the engagement, and the slider 10 drives the rack 6 to reset due to the rebound of the spring 9, thereby driving the filter 11 to continue to reset. While the rotating shaft 3 continues to rotate, the filter 11 will continue to move up and down, so that the debris falling on the filter 11 falls from the mesh into the dust box 16. After the processing is completed, the dust box 16 is pulled out to process the collected debris. The model of the motor 2 is SD130AEA26025-SH3. The above is the entire working principle of the utility model.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
