[0027] Example

[0028] See also Figure 1 , Figure 1 FIG. 1 is a schematic structural diagram of a floor grinding machine 100 provided in this embodiment.

[0029] The floor grinding machine 100 provided in this embodiment includes a body 110, a motor 120, a grinding disc 130 and a dust collecting assembly 140. The motor 120, the grinding disc 130 and the dust collecting assembly 140 are all arranged on the body 110. The grinding disc 130 and the dust collecting assembly 140 are both transmission-connected to the motor 120. The grinding disc 130 is used for grinding the floor under the drive of the motor 120. The dust collecting assembly 140 is used for absorbing dust generated by the grinding disc 130 when grinding the floor under the drive of the motor 120.

[0030] In actual application, when the floor grinder 100 is in normal operation, the motor 120 drives the grinding disc 130 to rotate and grind the floor, and the dust collecting assembly 140, driven by the motor 120, synchronously absorbs the dust generated by the grinding disc 130 grinding the floor, thereby avoiding the occurrence of dust. It can be seen that the dust collecting assembly 140 in this embodiment also uses the motor 120 as a power source, eliminating the need for an additional drive device, and has the characteristics of lower cost and more compact structure.

[0031] In fact, the floor grinding machine 100 provided in this embodiment also includes an electromagnetic clutch 150, and the dust collecting component 140 establishes or disconnects a transmission connection with the motor 120 through the electromagnetic clutch 150. It can be understood that when the ground to be constructed by the floor grinding machine 100 generates a large amount of dust, the dust collecting component 140 is connected to the motor 120 through the electromagnetic clutch 150, so that the dust collecting component 140 can also absorb dust synchronously while the motor 120 drives the floor grinding machine 100 to work. If the ground to be constructed by the floor grinding machine 100 is not easy to generate dust, the transmission between the dust collecting component 140 and the motor 120 can be disconnected through the electromagnetic clutch 150 to reduce power consumption.

[0032] In this embodiment, the body 110 has a grinding chamber 111 with an opening facing downward, the grinding disc 130 is arranged at the bottom of the grinding chamber 111 and at least partially protrudes from the opening of the grinding chamber 111, and the dust collecting assembly 140 is connected to the grinding chamber 111 for selectively absorbing and filtering the air in the grinding chamber 111.

[0033] In actual application, the dust generated by the grinding disc 130 grinding the ground is diffused in the grinding chamber 111, and the grinding chamber 111 can temporarily prevent the dust from diffusing into the environment. The dust collecting assembly 140 is connected to the grinding chamber 111, and can absorb and filter the air in the grinding chamber 111 under the drive of the motor 120, thereby completing the collection of dust.

[0034] Considering that a large noise will be generated when the grinding wheel 130 grinds the floor, in order to reduce the noise, in this embodiment, a sound-absorbing layer is provided on the cavity wall of the grinding chamber 111. The sound-absorbing layer has a porous surface structure and plays a role in noise reduction.

[0035] Please continue reading Figure 1In this embodiment, the dust collecting assembly 140 includes an impeller 141, a dust box 142 and an air inlet pipe 143. The dust box 142 is arranged on the body 110. One end of the air inlet pipe 143 is connected to the dust box 142, and the other end is connected to the grinding chamber 111. The impeller 141 is arranged on the dust box 142 and is transmission-connected to the motor 120.

[0036] The impeller 141 actually establishes or disconnects a transmission connection with the motor 120 through the electromagnetic clutch 150. When the impeller 141 is in transmission connection with the motor 120, the operation of the motor 120 will drive the impeller 141 to rotate, thereby generating negative pressure in the dust box 142 and sucking the air in the grinding chamber 111 through the air inlet pipe 143.

[0037] A filter 144 is provided in the dust box 142. The filter 144 blocks the space between the air inlet pipe 143 and the impeller 141 to filter dust in the airflow passing through. After the air mixed with dust in the grinding chamber 111 is sucked into the dust box 142, it passes through the filter 144 and flows toward the impeller 141. During this process, the dust in the airflow is blocked on the side away from the impeller 141 and collected by the dust box 142, while the clean airflow passes through the impeller 141 and flows into the atmosphere.

[0038] In this embodiment, the air inlet pipe 143 is connected to the top of the polishing chamber 111. Specifically, an air outlet is provided on the top wall of the polishing chamber 111, and one end of the air inlet pipe 143 away from the dust box 142 is connected to the air outlet. It should be noted that since the air outlet is provided on the top wall of the polishing chamber 111, in actual application, the air in the polishing chamber 111 can enter the air inlet pipe 143 from the direction farthest from the opening thereof, further preventing the air from flowing out of the opening of the polishing chamber 111.

[0039] In this embodiment, the dust collecting assembly 140 also includes an air outlet pipe 145, the suction end of the impeller 141 is connected to the dust collecting box 142, one end of the air outlet pipe 145 is connected to the blowing end of the impeller 141, and the other end of the air outlet pipe 145 extends vertically upward.

[0040] The air outlet 145 extends in the vertical direction, and can guide the clean air blown out by the impeller 141 to the space above the machine body 110, so as to avoid blowing directly around the operator and causing discomfort to the operator. In another embodiment, the end of the air outlet 145 away from the impeller 141 can be directed toward the motor 120, so as to achieve air cooling of the motor 120.

[0041] Taking into account that the airflow flowing into the dust box 142 may cause the dust previously collected in the dust box 142 to rise again and mix into the airflow, and be filtered multiple times at the filter 144, in this embodiment, in the vertical direction, the end of the air inlet pipe 143 away from the grinding chamber 111 is arranged in the upper space inside the dust box 142.

[0042] It is understandable that the dust collected first will accumulate at the bottom of the dust box 142 under the action of gravity, and the continuously flowing airflow enters the dust box 142 from the space above the dust box 142, is above the dust at the bottom of the box, and flows horizontally toward the filter 144 under the action of negative pressure, thereby avoiding causing the bottom dust to rise again.

[0043] In order to facilitate the regular cleaning of the dust box 142, in this embodiment, a selectively openable cleaning window is provided on the dust box 142. The operator can clean the dust collected in the dust box 142 with the cleaning window opened, and close the cleaning window during normal construction to prevent dust from flowing out.

[0044] In addition, in order to further improve the dust prevention effect, the floor grinding machine 100 provided in this embodiment also includes a spray system (not shown in the figure), which is arranged on the machine body 110 and has an atomizing spray head arranged on the top wall of the grinding chamber 111. In actual application, the spray system can deliver water to the atomizing spray head at high pressure, and under the action of the atomizing spray head, water mist is formed and sprayed in the grinding chamber 111, so as to achieve the effect of quickly eliminating dust.

[0045] In summary, the floor grinding machine 100 provided in this embodiment can avoid dust generation during the working process, and has the characteristics of good dust removal effect and low cost.

[0046] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
