Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a stone polishing machine with a water spraying device. Background Technology

[0002] A stone polishing machine with a water spray device is a mechanical device specifically designed for stone surface treatment. It combines polishing and water spraying functions to improve polishing efficiency, reduce dust pollution, and protect the health of operators.

[0003] Existing stone processing technologies, such as the water-grinding device disclosed in CN219358937U, use an electric telescopic rod to push the water grinder so that its bottom surface contacts the upper surface of the stone for grinding. A linear drive guide rail moves the electric telescopic rod left and right, thus horizontally grinding the upper surface of the stone. However, the following problems exist in its use:

[0004] The wastewater is recycled through the combination of the return pipe and the filter box, but the water cannot be sprayed evenly onto the stone, which can easily cause dust to be generated during the polishing process. This not only makes it easy for people to inhale the dust into their lungs and cause harm to their bodies, but also requires manual cleaning of the dust that flies out after polishing is completed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that water cannot be sprayed evenly onto the stone, and to propose a stone polishing machine with a water spraying device.

A polishing disc for polishing stone is arranged directly below the bracket. Two symmetrically arranged hollow rotating rods are rotatably installed inside the support box. Each of the two rotating rods is equipped with multiple nozzles for spraying water onto the stone. A driving mechanism is provided on the side wall of the support box for driving the two rotating rods to drive the nozzles to uniformly spray water onto the stone. A placement plate for placing the stone to be polished is fixedly installed inside the support box.

[0008] Preferably, the driving mechanism includes a fixed plate fixedly installed on the side wall of the support box, an electric push rod fixedly installed on the fixed plate, a sliding block fixedly installed at the upper end of the electric push rod, three equidistant connecting rods fixedly installed inside the sliding block, and racks fixedly installed at both ends of the three connecting rods. Two rotating gears are respectively meshed and connected to the two racks on both sides of the racks.

[0009] Preferably, the side wall of the support box is provided with a vertically arranged sliding groove, the sliding block is slidably disposed in the sliding groove, and the two rotating gears are respectively fixedly installed on the outer wall of the two rotating rods.

[0010] Preferably, a hydraulic rod is fixedly installed on the bracket, a drive motor is fixedly installed at the bottom end of the hydraulic rod, and the output end of the drive motor is fixedly connected to the grinding disc.

[0011] Preferably, the other ends of the two rotating rods are fixedly connected to a connecting pipe for supplying water to the rotating rods, and a water pump is fixedly installed at the end of the connecting pipe. A water storage tank fixedly connected to the water pump is fixedly installed on the side wall of the support box, and an inlet pipe for injecting water into the water storage tank is fixedly installed at the upper end of the water storage tank.

[0012] Preferably, a triangular-shaped guide plate for guiding water is fixedly installed at the bottom of the support box. Two mounting slots are opened inside the support box, and a filter plate for filtering water is provided in both mounting slots.

Four support legs for supporting the support box are fixedly installed at the bottom of the support box.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This utility model uses the combination of rack and pinion and rotating gear to make the nozzles on the two rotating rods rotate back and forth, so that the spray angle of the nozzles is increased, making it easier to spray water evenly on the stone, avoiding the generation of a large amount of dust during stone processing, and avoiding the harm to the human body caused by inhaling dust.

[0025] The drive mechanism includes a fixed plate 9 fixedly installed on the side wall of the support box 1. An electric push rod 10 is fixedly installed on the fixed plate 9. A sliding block 11 is fixedly installed on the upper end of the electric push rod 10. Three equidistant connecting rods 13 are fixedly installed inside the sliding block 11. A rack 14 is fixedly installed on both ends of the three connecting rods 13. Two rotating gears 8 are provided on both sides of the two racks 14 and are respectively meshed with the two racks 14.

[0026] The support box 1 has a vertically arranged sliding groove 12 on its side wall, and the sliding block 11 is slidably disposed in the sliding groove 12. Two rotating gears 8 are respectively fixedly installed on the outer wall of two rotating rods 6.

[0027] A hydraulic rod 16 is fixedly installed on the bracket 15, and a drive motor 17 is fixedly installed at the bottom of the hydraulic rod 16. The output end of the drive motor 17 is fixedly connected to the grinding disc 18.

[0028] The other ends of the two rotating rods 6 are fixedly connected to a connecting pipe 5 for supplying water to the rotating rods 6, and a water pump 4 is fixedly installed at the end of the connecting pipe 5. A water storage tank 2 fixedly connected to the water pump 4 is fixedly installed on the side wall of the support box 1. A water inlet pipe 3 for injecting water into the water storage tank 2 is fixedly installed at the upper end of the water storage tank 2.

[0029] A triangular-shaped guide plate 22 for guiding water is fixedly installed at the bottom of the support box 1.

[0030] The support box 1 has two through holes on both sides that are connected to the mounting groove 23. The sealing plate 25 is set in the through holes and is used to seal the through holes on both sides of the support box 1 to prevent water from flowing out of the through holes.

The two racks 14 drive the two rotating gears 8 to rotate in opposite directions, and the two rotating gears 8 drive the rotating rod 6 to rotate, which increases the angle of the water sprayed by the nozzle 7, so that the stone surface is sprayed with water evenly.

[0035] Water is directed to the two filter plates 24 by the guide plate 22 and discharged through the drain pipe 26, which facilitates water recycling.
