Background

In order to improve the ornamental value of the stone materials such as marble and granite, the surface of the stone material needs to be roughened, and after the stone material is roughened, a surface with certain roughness is formed. Generally, the surface of the stone is roughened by an impeller head, and the surface of the stone is struck by strong and dense shot thrown out by the impeller head, so that the surface of the stone smoothly drops to form certain roughness.

At present, the impeller head on the market can only roughen one face of the stone, if the stone is flat plate type stone, the existing impeller head can be only treated by roughening the upper surface, but for the stone of which the upper surface and the side face need to be roughened, one face needs to be roughened firstly, and then the other face needs to be roughened by turning over, so that the working efficiency is very low, and the cost is very high. When the joints of the top and the side walls of some stones are irregular (such as radians and grooves), the turning-over type secondary processing is adopted, so that part of the surfaces can be repeatedly processed, and the coarseness of the roughened stones is inconsistent. The shot blasting machine adopts a metal roller way and realizes automatic conveying of the stone by chain transmission, but the contact surface of the stone and the metal roller way is small, so that the stone conveying is not stable, and the shot is struck on the metal roller way, so that the probability of breaking the shot is increased. Shot ejected by the shot blasting machine can fall and need to be recycled, impurities such as dust and broken shot can be generated in the texturing process and mixed into qualified shot to form a shot mixture, the shot mixture is conveyed to the shot blasting machine by the aid of the hoister, and the service life and the shot blasting effect of the shot blasting machine can be influenced by the impurity contained in the shot mixture. The roughened stone material upper surface often has shot and dust to push away the amasss, and the direct transport of texturing paper goes out, can make partial shot can not recycle, also pollutes the surrounding environment of processing easily. In addition, the height design of the impeller head is unreasonable, and an operator is not easy to place stones, so that the working efficiency is affected.

As shown in fig. 2 and 8, the track-passing type shot blasting machine for stone materials further comprises a shot removing device 9, the shot removing device 9 comprises a shot removing fan 91 and a shot removing air pipe 92, the shot removing air pipe 92 is provided with two air receiving openings 921, the shot removing fan 91 is connected with the air receiving openings 921 through two pipelines (not shown), and a long inclined blowing opening 922 which is obliquely arranged is arranged below the shot removing air pipe 92. Except that the both ends welding of pill tuber pipe 92 has gear portion 923, the lateral wall edge is equipped with a plurality of height control teeth 924 that supply gear portion 923 to place about working bin 11, and height control teeth 924 is the slope setting. After the stone is subjected to roughening treatment, a small amount of scattered shot and dust impurities are generated on the surface of the stone and the crawler-type transmission belt 41, the shot removing fan 91 is started to blow air into the air receiving opening 921 and the shot removing air pipe 92 through a pipeline, and the air is blown out through the inclined blowing opening 922, so that the shot and the dust impurities roll to fall into the shot recycling bin 5 through the shot discharging hole 411. Because of the difference in height of stone material, consequently adjust through height-adjusting tooth 924 and remove the hanging position of fender portion 923 of pellet tuber pipe 92 for the commonality of equipment is stronger, makes the cyclic utilization rate of pellet improve, has also improved the surrounding environment of equipment.

The utility model provides a track through type shot-blasting machine design benefit for the stone material, the high reasonable of material loading adopts crawler-type drive belt 41 as carrying the medium, and stone material and crawler-type drive belt 41 area of contact are big, and the stone material is carried steadily. The shot is put into the shot throwing bin 2, the qualified shot, the broken shot and the dust are separated through the shot sand separation device 6, the qualified shot is conveyed into each shot blasting device 7, and the service life of each shot blasting device 7 is prolonged. The shots are thrown out from the shot blasting devices 7 at the top and the left and right sides of the working bin 11, the roughening treatment can be carried out on the surface of the stone from three directions of the stone, and the shots are collected and conveyed by the shot collecting and conveying screw 51 and then pass through the shot discharging and conveying screw 34. The thrown pills fall into the pill recovery bin 5 through the pill discharge holes 411 of the crawler-type transmission belt 41, and are conveyed into the pill throwing bin 2 through the pill recovery device 3 for cyclic utilization, the bottom of the lifting bin 31 is lower than the rack 1, the heights of the crawler-type transmission belt 41 and the feeding guide roller 46 are reduced under the condition that continuous circulation of the pills is guaranteed, and an operator can place stones conveniently. The throwing outlet 70 of the shot blasting device 7 is reasonable in design, so that the shot can be prevented from being impacted when being thrown out, and the probability of breaking the shot is reduced. Through the pill air duct 92 that removes of oblique mouthpiece 922 in the area, blow the pill and the dust impurity that crawler-type drive belt 41 and stone material surface were scattered and fall to in the pill recovery bin 5, improved the cyclic utilization of pill greatly, improved operational environment.

The foregoing is only a few embodiments of the present invention, and it should be noted that, for those skilled in the art, other modifications and improvements can be made without departing from the inventive concept of the present invention, and all of them belong to the protection scope of the present invention.
