Preferably, in order to achieve the purpose of dust removal, the gas collection assembly comprises a power plate 23, a power disc 22, a power shaft 21 and two hoses 24, one end of the power shaft 21 is connected with one end of the screw rod 7, which is far away from the motor 6, the power shaft 21 and the screw rod 7 are coaxially arranged, the other end of the power shaft 21 is connected with the position, which is far away from the center of circle, of the power disc 22, the power plate 23 is arranged inside the base 3, the power plate 23 is connected with the inner wall of the base 3 in a sealing and sliding manner, one side of each of the two power plates 23 is connected with two ends of a second spring 25, the other side of the power plate 23 abuts against the periphery of the power disc 22, first round holes are formed above and below the power plate 23, two second round holes are formed on two sides of the base 3, two ends of the hose 24 are connected with the inner walls of the first round holes and the second round holes, the hose 24 is communicated with the inside of the base 3, and a second one-way valve is arranged in each of the hose 24 and the telescopic pipe 26 and is electrically connected with the PLC.

When the lead screw 7 rotates, can drive power shaft 21 and rotate, make power disc 22 rotate, thereby can realize the function of power plate 23 round trip movement in base 3, move to the direction of keeping away from each other when two power plates 23, can make the outside air of base 3 pass through hose 24 and get into between two power plates 23, when two power plates 23 move to the direction of being close to each other, can make the inside of the leading-in dust removal box 27 of air through flexible pipe 26 between two power plates 23, thereby realize the function of the dust removal of blowing to the surface of the stone material on base 4, make stone material surface can not adhesion impurity, thereby can not influence the precision of polishing, the reliability of equipment has been improved.

When the grinding work is needed, a user places the stone above the base 4, and then controls the lifting assembly to work to drive the dust cover 9 to move downwards, so that the stone can be located in the dust cover 9, when the abutting plate 10 abuts against the upper side of the stone and the dust cover 9 continues to move downwards, the abutting plate 10 and the clip notch can relatively move to drive the driving unit to work, so that the two pistons 15 move towards the direction away from each other, the first spring 16 is stretched, so that the air in the dust cover 9 is led into the inner part of the air cylinder 17 through the connecting pipe 18, the air pressure in the dust cover 9 can be reduced, the air pressure difference is formed between the inside and the outside of the dust cover 9, and the dust cover 9 can be adsorbed on the stone, because the position of the dust cover 9 is fixed, the position of the stone can be limited, and the stone can not deviate during the grinding work, thereby can not exert an influence to the work of polishing to improve the reliability of equipment, through the dust cover 9 that sets up, can shelter from the work of collecting to the splash that produces when polishing, make the splash that produces when polishing concentrated in the inside of dust cover 9, thereby reduced the probability that the user was hurt to the splash, thereby improved the security of equipment. When carrying out dust removal work, control cylinder 28 starts, extend or withdraw the gas pole, can realize the function that dust removal box 27 reciprocated, make the exhaust hole on dust removal box 27 can be located the top of stone material, make the air in dust removal box 27 can blow to the surface of the top of stone material, the work of the lifting unit of the additional control, drive the work of gas collection subassembly, make the outside air of base 3 can be through the inside of the leading-in dust removal box 27 of flexible pipe 26, thereby the realization is blown the function of removing dust to the surface of the stone material on base 4, make the stone material surface can not adhesion impurity, thereby can not influence the precision of polishing, the reliability of equipment has been improved.

Compared with the prior art, the stone grinding equipment with high stability can ensure that the dust cover 9 can be adsorbed on the stone through the stabilizing mechanism, thereby limiting the position of the stone, ensuring that the stone can not deviate when grinding is carried out, thereby not influencing the grinding work, improving the reliability of the equipment, and also realizing the function of shielding and collecting, ensuring that splashes generated during grinding are concentrated in the dust cover 9, thereby reducing the probability of damaging a user by the splashes, further improving the safety of the equipment, compared with the prior stabilizing mechanism, the stabilizing mechanism can also realize the function of removing dust for the abutting plate 10, thereby not increasing the friction force when the abutting plate 10 moves in the square notch, avoiding influencing the sealing performance of the dust cover 9, thereby not generating the phenomenon of air leakage, and preventing the influence on the adsorption effect, the reliability is higher, through dust removal mechanism, realizes blowing the function of removing dust to the surface of the stone material of co-altitude on base 4 for the stone material surface can not adhesion impurity, thereby can not influence the precision of polishing, has improved the reliability of equipment, compares with current dust removal mechanism, and this dust removal mechanism and stabilizing mean link gear as an organic whole have improved the practicality of equipment.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
