[0023] like Figures 1 to 6 As shown, a floor grinder includes a base plate 1, a protective frame 2 is fixedly connected to the rear end of the top of the base plate 1, casters 3 are installed at the four corners of the bottom, a push handle 4 is installed on the protective frame 2, an opening is opened at the front of the base plate 1, and a fixing frame 5 is provided at the top of the base plate 1 above the opening, the fixing frame 5 is an inverted U-shaped frame, and a grinding component 6 is provided on the inner side thereof, a cleaning component 7 is provided on the rear side of the grinding component 6, an equipment box 8 is provided on the top of the base plate 1 inside the protective frame 2, a dust collection component 9 is provided above the equipment box 8, a battery 10 is provided inside, and an inverter 11 and a circuit board 12 are provided on both sides of the battery 10, respectively.

[0024] The grinding assembly 6 includes a mounting seat 6.1, a motor 6.2 is mounted on the top of the mounting seat 6.1, a mounting plate 6.3 is fixedly connected to the output shaft of the motor 6.2, a grinding disc 6.4 is detachably mounted on the bottom of the mounting plate 6.3, a protective ring 6.5 is detachably mounted on the outer side of the mounting seat 6.1, an electric cylinder 6.6 is symmetrically connected to both sides of the motor 6.2 on the top, the protective ring 6.5 is a rubber ring, and a plurality of ventilation holes are arranged at the bottom; the height of the bottom edge of the protective ring 6.5 is lower than the height of the grinding disc 6.4 from the ground; the cylinder body of the electric cylinder 6.6 is fixedly connected to the fixing frame 5.

[0025] The extension and retraction of the electric cylinder 6.6 can drive the mounting seat 6.1 to rise and fall, thereby realizing the height adjustment of the grinding disc 6.4. The protection ring 6.5 can effectively prevent the dust generated during grinding from being dispersed into the air and polluting the working environment.

[0026] The cleaning assembly 7 comprises an electric cylinder 7.1, the output end of which is fixedly connected with a mounting bar 7.2, and a cleaning bar 7.3 is detachably mounted on the bottom of the mounting bar 7.2, and the cleaning bar 7.3 is a scouring pad or cleaning cotton.

[0027] The expansion and contraction of the electric cylinder 7.1 causes the installation bar 7.2 to drive the cleaning bar 7.3 to move up and down. When the cleaning bar 7.3 abuts against the floor surface, the grinding machine is pushed to move, thereby realizing automatic cleaning of the ground after grinding.

[0028] The dust collection assembly 9 comprises a dust collection box 9.1, a dust collection fan 9.2 is installed on the top of the dust collection box 9.1, two partitions 9.3 are symmetrically arranged on the upper inner part, a filter plate 9.4 is installed between the two partitions 9.3, the filter plate 9.4 is a semicircular structure protruding upward, and a rotating shaft 9.5 is arranged at the center of the circle, two brush strips 9.6 are installed on the rotating shaft 9.5, a dust guide pipe 9.7 is connected to the middle of the front end of the dust collection box 9.1, a dust discharge port is arranged at the lower rear end, a cover plate 9.8 is arranged at the dust discharge port, the rotating shaft 9.5 is rotatably installed inside the dust collection box 9.1, and one end thereof passes through the surface of the dust collection box 9.1 and is fixedly connected to a hand wheel 9.9, the dust guide pipe 9.7 is connected to the mounting seat 6.1, and a control panel 13 is installed on the top of the rear end of the dust collection box 9.1.

[0029] The dust collecting fan 9.2 works, so that the dust inside the protective ring 6.5 enters the dust collecting box 9.1 through the dust guide pipe 9.7 and is cached, so as to collect the dust generated by grinding. When the dust blocks the filter plate 9.4, the rotating shaft 9.5 is rotated by the hand wheel 9.9, and the rotating shaft 9.5 drives the brush bar 9.6 to rotate, and the dust on the filter plate 9.4 can be brushed off by the brush bar 9.6.

[0030] In specific use, the grinder is moved to the position where the floor needs to be grinded by the push handle 4, the grinding disc 6.4 is adjusted to a suitable height by extending the electric cylinder 1 6.6, and the motor 6.2 drives the grinding disc 6.4 to rotate to grind the floor. As the grinding progresses, the electric cylinder 1 6.6 continues to slowly extend so that the floor can be polished flat; the protective ring 6.5 can effectively prevent the dust generated during grinding from drifting into the air, and the dust on the inside of the protective ring 6.5 enters the dust collection box 9.1 through the dust guide pipe 9.7, thereby effectively preventing dust from polluting the working environment; when the cleaning strip 7.3 is prompted to move downward and abut against the floor surface by extending the electric cylinder 2 7.1, the grinder is pushed to move, so that the polished floor can be cleaned.
