DETAILED DESCRIPTION

[0022] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] Example 1

[0024] A concrete grinding machine, see Figure 1-Figure 3 As shown, it includes a fixed plate 1, a motor 2, a grinding block 3, a protective cover 4, a universal wheel 11, a push rod 12 and a dust suction mechanism. The motor 2 is installed on the front side of the top of the fixed plate 1. The bottom of the output shaft of the motor 2 is connected to the grinding block 3 through a coupling. The grinding block 3 can grind the concrete floor when it rotates. The protective cover 4 is welded on the front side of the bottom of the fixed plate 1. The grinding block 3 is located inside the protective cover 4. The universal wheel 11 is symmetrically rotatably arranged on the rear side of the bottom of the fixed plate 1. The universal wheel 11 is used to move the device. Push rods 12 are connected to the left and right sides of the rear side of the top of the fixed plate 1 to facilitate people to push the device to move. The push rod 12 is L-shaped. A dust suction mechanism is arranged on the fixed plate 1.

[0025] See also Figure 2-Figure 3 As shown, the dust collection mechanism includes a dust collecting cylinder 5, a dust collection pipe 6 and a fan 7. The dust collecting cylinder 5 is welded in the middle of the top of the fixed plate 1. The middle of the top of the dust collecting cylinder 5 is connected with the dust collection pipe 6. The front end of the dust collection pipe 6 passes through the bottom of the protective cover 4. The fan 7 is installed on the upper end of the dust collection pipe 6. The fan 7 is located inside the dust collecting cylinder 5. The fan 7 can suck dust into the dust collecting cylinder 5.

[0026] When the device needs to be used, people first push the device to the specified position so that the grinding block 3 contacts the concrete floor, and then people start the motor 2 and the fan 7. The output shaft of the motor 2 rotates to drive the grinding block 3 to rotate. The rotation of the grinding block 3 can grind the concrete floor. The protective cover 4 can block the grinding block 3 and play a role in dust protection. At the same time, people need to push the device to move so that a large area of ​​the concrete floor can be grinded. While the concrete floor is being polished, the fan 7 can suck in the dust floating in the air and entering the protective cover 4, so that the dust is sucked into the dust collecting tube 5 through the dust suction pipe 6, so as to achieve the purpose of dust removal, thereby reducing the dust inhaled into the body by people. When the grinding of the concrete floor is completed, people can turn off the motor 2 and the fan 7.

[0027] Example 2

[0028] Based on Example 1, see Figure 4 As shown, it also includes a water tank 8, a water pump 9 and a delivery pipe 10. The water tank 8 is welded to the rear side of the top of the fixed plate 1. The water tank 8 is made of transparent material, which is convenient for people to see the water level in the water tank 8. The water pump 9 is installed on the right side of the bottom of the water tank 8. The water outlet pipe of the water pump 9 runs through the top of the water tank 8. The delivery pipe 10 is connected to the left side of the water outlet pipe of the water pump 9. The delivery pipe 10 runs through the top of the water tank 8. The delivery pipe 10 sprays water outward to degrade dust.

[0029] When it is necessary to deal with the dust floating in the air, people can pour a proper amount of water into the water tank 8 and then start the water pump 9. The water pump 9 can absorb the water in the water tank 8 and spray the water in the water tank 8 out through the delivery pipe 10, so as to degrade the dust in the air and achieve a better dust removal purpose. When the dust removal is completed, the water pump 9 can be turned off.
