[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The metal grinding device with a dust suction structure starts the machine head to drive the grinding wheel to rotate. When the grinding wheel is close to the metal workpiece, the protective cover outside the grinding wheel first contacts the surface of the workpiece. After the protective cover is subjected to force, it will drive multiple sliding bars to slide on the support plate until the grinding wheel contacts the surface of the workpiece. The elastic force of the spring is used to support the protective cover so that the protective cover can be close to the workpiece, so that the debris and dust generated by grinding can be isolated by the protective cover. The adsorption component can suck the dust and debris into the box body in cooperation with the work of the fan, so as to achieve the purpose of fixed-point dust suction and prevent dust from scattering to pollute the environment and debris from splashing to cause safety hazards to personnel.
[0013] 2. The metal polishing device with a dust suction structure uses a fan to operate the branch pipe to extract air from the box body. Dust and debris can be sucked into the filter cartridge in the box body by the dust suction pipe. The filter cartridge can filter the air containing dust and debris to avoid emission pollution. When cleaning impurities in the filter cartridge, the fan injects air into the box body and blows out impurities outside the filter cartridge by backflushing, thereby clearing the filter cartridge. After opening the discharge valve, impurities in the filter cartridge can be flushed out without removing the filter cartridge for operation, thereby improving operational convenience and cleaning effect.

DETAILED DESCRIPTION
[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a metal grinding device with a dust suction structure, comprising a machine handle 1, a machine head 2 is provided at one end of the machine handle 1, a handle 13 is provided on the side of the machine handle 1 away from the machine head 2, and the handle 13 is provided with anti-slip grooves on the outside, and a U-shaped handle 14 is installed on the top of the machine handle 1. Through the mutual cooperation between the handle 14 and the handle 13, the handle 13 and the handle 14 are respectively held by both hands to facilitate holding the grinding device, thereby improving the stability of the grinding work and being easy to carry.
[0021] A support plate 4 and a grinding wheel 3 are installed at the bottom of the machine head 2. The grinding wheel 3 is located below the support plate 4. A protective cover 5 is provided outside the grinding wheel 3. A plurality of support components 6 are installed between the protective cover 5 and the support plate 4. The support component 6 includes a slide bar 601. One end of the slide bar 601 is fixed to the protective cover 5. There are six support components 6, and a stopper 602 is fixed to the other end of the slide bar 601.
[0022] The slide bar 601 is arranged on the support plate 4, and a spring 603 is connected to the outer sleeve of the slide bar 601. The spring 603 is located between the support plate 4 and the protective cover 5. Through the mutual cooperation between the spring 603 and the protective cover 5, when the protective cover 5 is in close contact with the workpiece, the elastic force of the spring 603 can play a role in supporting the protective cover 5, so that the protective cover 5 is not easy to separate from the workpiece, thereby improving the dustproof effect of the protective cover 5.
[0023] A plurality of adsorption components 8 are disposed outside the protective cover 5. The number of adsorption components 8 is four, and the adsorption components 8 include a dust suction pipe 801. One end of the dust suction pipe 801 is disposed through the protective cover 5. The protective cover 5 is transparent, which is convenient for observing the grinding position and grinding status.
[0024] A one-way valve 802 is provided at a position of the dust suction pipe 801 near the filter cartridge 9. The one-way valve 802 can prevent air from flowing back in the dust suction pipe 801 and causing blockage.
[0025] The end of the dust suction pipe 801 is penetrated in the filter cartridge 9, and a discharge valve 12 is provided outside the filter cartridge 9. The discharge valve 12 penetrates the box body 7. Because of the discharge valve 12, the fan 10 injects air into the box body 7, and the impurities in the filter cartridge 9 can be flushed out of the discharge valve 12, which is convenient for cleaning the impurities inside the box body 7.
[0026] The other end of the plurality of adsorption components 8 is provided with the same box body 7, in which a filter cartridge 9 is installed, and a fan 10 is installed on the top of the box body 7. The air inlet of the fan 10 is connected to three branch pipes 11, which are arranged through the top of the box body 7 and between the filter cartridge 9 and the inner wall of the box body 7, so that the branch pipes 11 can extract the gas filtered by the filter cartridge 9.
[0027] The working principle of the utility model is:
[0028] When in use, start the machine head 2 to drive the grinding wheel 3 to rotate, hold the handle 13 and the handle 14 to bring the grinding wheel 3 close to the metal workpiece, and the protective cover 5 will first contact the surface of the workpiece. After the protective cover 5 is subjected to force, it will drive multiple slide bars 601 to slide on the support plate 4 until the grinding wheel 3 contacts the surface of the workpiece, and the debris and dust generated by grinding can be isolated by the protective cover 5. The fan 10 works to make the branch pipe 11 draw air from the box body 7, and the dust and debris can be sucked into the filter cartridge 9 in the box body 7 by the dust suction pipe 801. The filter cartridge 9 can filter the air containing dust and debris. When cleaning the impurities in the filter cartridge 9, the fan 10 works to inject air into the box body 7, and blows out the impurities outside the filter cartridge 9 by backflushing. The one-way valve 802 prevents the gas from flowing back in the dust suction pipe 801, so that the impurities in the filter cartridge 9 can be discharged from the discharge valve 12.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
