[0023] Please see Figures 1 to 6 This application discloses an improved exhaust system device for a grinding machine, comprising a support frame 10 and a cover plate 20. The support frame 10 includes a base plate 14 and side plates 11. Specifically, the base plate 14 is a flat plate with a through hole 15 corresponding to the exhaust port of the grinding machine 100. The side plates 11 have a first side and a second side arranged opposite each other along their width. Preferably, there are two side plates 11; the first side of one side plate 11 is fixedly connected to one side of the base plate 14, and the first side of the other side plate 11 is fixedly connected to the other side of the base plate 14. Preferably, the side plates 11 and the base plate 14 are integrally formed, for example, by bending with a bending machine. To prevent the exhaust air from blowing directly, a cover plate 20 is also provided, with one end of the cover plate 20 rotatably connected to the side plate 11.

[0024] This application, by adding an improved device 200 to the exhaust port of the grinder 100, can prevent the exhaust air of the grinder 100 from blowing directly onto people or objects. Specifically, the exhaust air of the grinder 100 is changed in direction by the cover plate 20, thereby avoiding blowing directly onto people or objects and solving the defects of existing grinders.

[0025] In a preferred embodiment of this application, the side plate 11 has a first end and a second end disposed opposite to each other along its length. The width of the second end of the side plate 11 is greater than the width of the first end of the side plate 11. This allows the exhaust air from the grinder 100 to be reflected by the cover plate 20 and discharged from the second end of the side plate 11 without flowing back into the grinder 100. To reduce noise and improve the exhaust of hot air, the side plate 11 is provided with a plurality of heat dissipation grooves 16, allowing the exhaust air from the grinder 100 to be discharged not only from the second end of the side plate 11 but also from the heat dissipation grooves 16.

[0026] As a preferred embodiment of this application, one end of the cover plate 20 is provided with a connecting pipe 21. Preferably, the connecting pipe 21 and the cover plate 20 are fixedly connected, such as by welding or integral molding design. The first end of the side plate 11 is provided with a bolt 12. Specifically, the first end of each side plate 11 is provided with a bolt 12. The cover plate 20 is rotatably connected to the side plate 11 by the bolt 12 inserted into the connecting pipe 21. That is, the cover plate 20 can rotate by the two bolts 12 inserted into the connecting pipe 21, so that the cover plate 20 can rotate relative to the side plate 11.

[0027] As a preferred embodiment of this application, a retaining ring 40 is also provided at the through hole 15 of the base plate 14, and the base plate 14 is rotatably connected to the grinding machine 100 through the retaining ring 40. Specifically, a fixed pipe 50 is connected to the air outlet of the grinder 100. The side of the fixed pipe 50 has a convex shape, with the smaller end of the convex shape fixed to the grinder 100. The diameter of the through hole 15 in this application is slightly larger than the outer diameter of the fixed pipe 50, so that the base plate 14 can be fitted onto the fixed pipe 50. In order to lock the base plate 14, the retaining ring 40 in this application has an opening 41. The inner and outer diameters of the retaining ring 40 can be increased within the elastic range through the opening 41. So when the retaining ring 40 is bent outward through the opening 41, the radius of the retaining ring 40 increases, so that the retaining ring 40 can be fitted onto the fixed pipe 50. The inner diameter of the retaining ring 40 is similar to that of the through hole 15, and the outer diameter of the retaining ring 40 is larger than the diameter of the through hole 15. In this way, the retaining ring 40 can restrict the base plate 14 onto the fixed pipe 50, and the base plate 14 can rotate on the fixed pipe 50, so that the improved device 200 can rotate on the grinder 100.

[0028] In a preferred embodiment of this application, the second sides of the two side plates 11 are fixedly connected by a connecting frame 13, which ensures the stability of the entire support frame 10 and prevents it from deforming.

[0029] In a preferred embodiment of this application, a positioning pin 30 is also installed at the second end of the side plate 11. The positioning pin 30 cooperates with the cover plate 20, and the positioning pin 30 can limit the other end of the cover plate 20. Specifically, the positioning pin 30 includes a storage part 31, a connecting part 32 fixedly connected to the storage part 31, and a limiting part 33 partially disposed inside the connecting part 32. The limiting part 33 is partially disposed inside the connecting part 32, and the other part of the limiting part 33 protrudes from the connecting part 32 and limits the cover plate 20. The limiting part 33 is connected to one end of a spring, and the other end of the spring is connected to the storage part 31. The spring (not shown in the figure) is disposed inside the storage part 31, and the limiting part 33 can be made to have elasticity by means of the spring. The connecting part 32 is provided with an external thread, and the positioning pin 30 is connected to the side plate 11 by a screw. The side plate 11 is provided with a screw hole (which coincides with the positioning pin 30 and is not marked).

[0030] The above are merely preferred embodiments of this application. The scope of protection of this application is not limited to the above embodiments. All technical solutions falling within the scope of this application's concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should be considered within the scope of protection of this application.
