[0002] As a high-end building decoration material, stone is now widely used in indoor and outdoor decoration. Common stones on the market are mainly divided into natural stone and artificial stone. With the continuous development and progress of society and technology, artificial stone products are becoming more and more refined, and their quality and appearance are no longer inferior to natural stone. Building stones need to be sandblasted before use. The Chinese utility model patent with announcement number CN214642864U discloses a stone sandblasting machine. The prior art uses a compressed air pump to input gas into the containing box, and sprays the mixture of gas and fine sand through the spray gun of the discharge pipe. However, the prior art cannot realize the recycling of sandblasting, and the clamping of the sprayed object is not stable.

[0004] The building stone is placed in the clamping device, the building stone is clamped by the clamping device, and the building stone is sandblasted by the movable device in cooperation with the ejection device.

[0005] Furthermore, the box device includes a bottom wheel arranged at the bottom of the outer box, a liquid barrel is fixedly installed on the bottom plate, a flip cover is rotatably installed on the outer box, an inner sliding sleeve is fixedly installed on the inner slope plate, a liquid return pipe is fixedly installed at the bottom of the inner slope plate, the liquid return pipe is fixedly installed with the liquid barrel, and a bottom plate is fixedly installed at the bottom of the bottom plate.

[0006] Furthermore, a slope is provided inside the inner slope plate, and the slope slopes toward the liquid return pipe.

[0007] The liquid barrel is filled with sandblasting liquid, that is, water mixed with sandblasting particles. The liquid barrel outputs sandblasting liquid to the spraying device, and the building stone is sandblasted through the spraying device. After the sandblasting is completed, the sandblasting water flows into the return pipe through the slope of the inner slope plate, and the sandblasting waste water returns to the liquid barrel through the return pipe.

[0008] Furthermore, the movable device includes a motor wheel fixedly mounted on the motor shaft of the motor, an end swivel seat fixedly mounted on the bottom of the top plate, a bidirectional screw rod rotatably mounted on the end swivel seat, a screw wheel fixedly mounted on the end of the bidirectional screw rod, a transmission belt wrapped around the motor wheel and the screw wheel, a movable frame slidably mounted on the top plate, the movable frame and the bidirectional screw rod form a threaded transmission, a switch mechanism is arranged on the movable frame, and a switching mechanism is arranged on the end swivel seat.

[0009] Furthermore, the switch mechanism includes an extending frame fixedly mounted on the movable frame, a switch cylinder is fixedly mounted on the extending frame, an upper spray pipe is fixedly mounted on the switch cylinder, a lower connecting pipe is fixedly mounted on the bottom of the switch cylinder, the lower connecting pipe is fixedly mounted on the liquid filling barrel, a rotating piece is rotatably mounted on the switch cylinder, and a rotating gear is fixedly mounted on the rotating piece.

[0010] Furthermore, the switching mechanism includes a transverse frame slidably mounted on the end swivel seat, a lower moving frame is fixedly mounted on the bottom of the transverse frame, an upper trapezoidal block is fixedly mounted on the bottom of the lower moving frame, a lower guide column is fixedly mounted on the inner plate, a descending rod is slidably mounted on the lower guide column, a downward pressure spring is arranged between the descending rod and the inner plate, a lower trapezoidal block is fixedly mounted on the descending rod, the lower trapezoidal block is slidably mounted with the upper trapezoidal block, a proximal column is fixedly mounted on the descending rod, a proximal rack is fixedly mounted on the proximal column, the proximal rack is meshed with the rotating gear, a distal column is fixedly mounted on the descending rod, and a distal rack is fixedly mounted on the distal column.

[0011] The rotation of the motor drives the motor wheel to rotate, thereby driving the screw wheel and the two-way screw to rotate through the transmission belt, thereby driving the movable frame to slide along the top plate. In the initial state, the switch cylinder is in a closed state, that is, the rotating piece is in a horizontal state. When the movable frame moves, due to the meshing of the proximal rack with the rotating gear, the proximal rack will drive the rotating gear and the rotating piece to rotate. When the rotating gear is disengaged from the proximal rack, the rotating piece and the rotating gear just rotate ninety degrees. At this time, the rotating piece is in a vertical state, and the sandblasting liquid in the liquid filling barrel enters the upper spray pipe through the lower pipe and is finally sprayed out through sandblasting. At the same time, in conjunction with the sliding of the movable frame, the spraying device is driven to sandblast the building stone. When the rotating gear begins to mesh with the distal rack, the distal rack will drive the rotating gear and the rotating piece to rotate. When the rotating gear is disengaged from the distal rack, the rotating gear and the rotating piece rotate ninety degrees. At this time, the rotating piece is in a parallel state, and the switch cylinder is closed.

[0012] A bidirectional screw rod is arranged on the bidirectional screw rod, so the continuous rotation of the motor wheel will drive the movable frame to move forward along the bidirectional screw rod to the farthest end and then back to the nearest end, and so on.

[0013] When the movable frame drives the spraying device but has not started sandblasting the building stone, the rotating piece is already in a vertical state. When the sandblasting is completed, the rotating piece is still in a vertical state. The movable frame continues to move forward to drive the rotating piece to close.

[0014] The lower frame and the lower frame are in a state of being moved downwardly, and the lower frame and the upper frame are in a state of being moved downwardly, so that the lower frame and the lower frame can move upwardly, and the lower frame and the upper frame are in a state of being moved downwardly, so that the lower frame and the lower frame can move upwardly, and the lower frame and the upper frame are in a state of being moved downwardly, so that the lower frame and the lower frame can move upwardly, and the lower frame can move upwardly, and the lower frame can move upwardly, so that the lower frame ...

[0015] When the movable frame returns to its original position, it will contact the left end of the transverse frame, driving the transverse frame to slide to the left in the end swivel seat, thereby driving the upper trapezoidal block to leave the top of the lower trapezoidal block and return to the initial position. The downward pressure spring rebounds, driving the descending rod and the lower trapezoidal block to rise, and the descending rod also returns to the initial position, and the distal rack and the proximal rack also return to the initial height.

[0016] Furthermore, the spraying device includes an upper and lower flip pipe rotatably mounted on a movable frame, a spray gun is fixedly mounted on the upper and lower flip pipes, a left and right rotating block is rotatably mounted on the upper and lower flip pipes, a connecting rod is fixedly mounted on the left and right rotating blocks, a rotating rod is rotatably mounted on the connecting rod, a lower gear is rotatably mounted on the movable frame, the rotating rod is rotatably mounted with the movable frame, an upper gear is fixedly mounted on the rotating rod, the upper gear is meshed with the lower gear, a long rack is fixedly mounted on the top plate, the long rack is meshed with the lower gear, and the spray gun is fixedly mounted with the upper spray pipe.

[0017] The sandblasting liquid in the lower pipe is sprayed out through the spray gun. During the sliding process of the movable frame, the lower gear and the upper gear are driven to rotate through the meshing of the lower gear and the long rack, thereby driving the rotating rod to rotate, and thus driving the upper and lower turning pipes to continuously rotate around the movable frame through the connecting rod, thereby driving the spray gun to swing up and down, that is, the left and right turning blocks slide left and right and swing up and down at the same time, thereby realizing comprehensive sandblasting of the building stone.

[0018] Furthermore, the clamping device includes a pedal frame rotatably mounted on the bottom ear plate, a lower pedal is fixedly mounted on the pedal frame, a descending column is slidably mounted in the inner sliding sleeve, a trailer is fixedly mounted on the top of the descending column, building stones are placed on the trailer, a lower push plate is fixedly mounted on the descending column, a side column is slidably mounted on the clamping frame, a side clamp is fixedly mounted on the side column, a side spring is arranged between the side column and the clamping frame, a side blocking frame is rotatably mounted on the clamping frame, a side convex column is fixedly mounted on the side blocking frame, the side convex column slides and rotates in the waist hole of the side column, and a blocking ball is fixedly mounted on the side blocking frame.

[0019] The building stone to be sandblasted is placed on the carriage. The gravity of the building stone will drive the carriage and the descending column to descend along the inner sliding sleeve. The descending column will drive the tread frame to rotate, thereby hitting the blocking ball, thereby driving the blocking ball to descend, thereby driving the side blocking frame to rotate relative to the clamping frame, thereby driving the side column and the side clamping piece to slide inward through the side convex column, and the side spring is squeezed, thereby clamping the building stone through the side column. When the building stone is sandblasted, the pedal is stepped on by the foot to drive the tread frame to rotate, thereby driving the descending column and the carriage to rise, and the side spring rebounds, so that the side column no longer clamps the building stone.

[0035] like Figure 2 , Figure 3 As shown, the box device includes a bottom wheel 102 arranged at the bottom of the outer box 101, a liquid barrel 107 is fixedly installed on the bottom plate 108, a flip cover 103 is rotatably installed on the outer box 101, an inner sliding sleeve 111 is fixedly installed on the inner slope plate 105, a liquid return pipe 110 is fixedly installed at the bottom of the inner slope plate 105, the liquid return pipe 110 is fixedly installed with the liquid barrel 107, and the bottom plate 108 is fixedly installed at the bottom of the bottom plate 108.

[0036] like Figure 2 As shown, an inclined surface is provided inside the inner slope plate 105 , and the inclined surface slopes toward the liquid return pipe 110 .

[0037] The liquid barrel 107 is filled with sandblasting liquid, that is, water mixed with sandblasting particles. The liquid barrel 107 outputs the sandblasting liquid to the spraying device, and the building stone is sandblasted through the spraying device. After the sandblasting is completed, the sandblasting water flows through the slope of the inner slope plate 105 to the return liquid pipe 110, and the sandblasting waste water returns to the liquid barrel 107 through the return liquid pipe 110.

[0038] like Figure 4-Figure 6 As shown, the movable device includes a motor wheel 202 fixedly mounted on the motor shaft of the motor 201, an end swivel seat 205 fixedly mounted on the bottom of the top plate 104, a bidirectional screw rod 206 is rotatably mounted on the end swivel seat 205, a screw wheel 204 is fixedly mounted on the end of the bidirectional screw rod 206, a transmission belt 203 is wrapped around the motor wheel 202 and the screw wheel 204, a movable frame 207 is slidably mounted on the top plate 104, the movable frame 207 and the bidirectional screw rod 206 form a threaded transmission, a switch mechanism is arranged on the movable frame 207, and a switching mechanism is arranged on the end swivel seat 205.

[0039] like Figure 4-Figure 6 As shown, the switch mechanism includes an extension frame 217 fixedly mounted on the movable frame 207, a switch cylinder 218 fixedly mounted on the extension frame 217, an upper nozzle 221 fixedly mounted on the switch cylinder 218, a lower connecting pipe 222 fixedly mounted on the bottom of the switch cylinder 218, the lower connecting pipe 222 is fixedly mounted on the liquid barrel 107, a rotating piece 219 is rotatably mounted on the switch cylinder 218, and a rotating gear 220 is fixedly mounted on the rotating piece 219.

[0040] like Figure 4-Figure 6 As shown, the switching mechanism includes a transverse frame 208 slidably mounted on the end swivel seat 205, a lower movable frame 209 is fixedly mounted on the bottom of the transverse frame 208, an upper trapezoidal block 210 is fixedly mounted on the bottom of the lower movable frame 209, a lower guide column 213 is fixedly mounted on the inner plate 106, a descending rod 212 is slidably mounted on the lower guide column 213, a downward pressure spring 214 is arranged between the descending rod 212 and the inner plate 106, a lower trapezoidal block 211 is fixedly mounted on the descending rod 212, the lower trapezoidal block 211 is slidably mounted with the upper trapezoidal block 210, a proximal column 223 is fixedly mounted on the descending rod 212, a proximal rack 224 is fixedly mounted on the proximal column 223, the proximal rack 224 is meshed with the rotating gear 220, a distal column 215 is fixedly mounted on the descending rod 212, and a distal rack 216 is fixedly mounted on the distal column 215.

[0041] The motor 201 rotates to drive the motor wheel 202 to rotate, thereby driving the screw wheel 204 and the bidirectional screw 206 to rotate through the transmission belt 203, thereby driving the movable frame 207 to slide along the top plate 104. In the initial state, the switch cylinder 218 is in a closed state, that is, the rotating piece 219 is in a horizontal state. When the movable frame 207 moves, since the proximal rack 224 is engaged with the rotating gear 220, the proximal rack 224 will drive the rotating gear 220 and the rotating piece 219 to rotate. When the rotating gear 220 is disengaged from the proximal rack 224, the rotating piece 219 and the rotating gear 220 just rotate ninety degrees. At this time, the rotating piece 219 is in a vertical state, and the sandblasting liquid in the liquid barrel 107 enters the upper nozzle 221 through the lower pipe 222 and is finally sprayed out through sandblasting. At the same time, in conjunction with the sliding of the movable frame 207, the spraying device is driven to sandblast the building stone. When the rotating gear 220 begins to mesh with the distal rack 216, the distal rack 216 will drive the rotating gear 220 and the rotating piece 219 to rotate. When the rotating gear 220 is disengaged from the distal rack 216, the rotating gear 220 and the rotating piece 219 rotate ninety degrees. At this time, the rotating piece 219 is in a parallel state, and the switch cylinder 218 is closed.

[0042] A bidirectional screw rod is arranged on the bidirectional screw rod 206 , so the continuous rotation of the motor wheel 202 will drive the movable frame 207 to move forward to the farthest end along the bidirectional screw rod 206 and then return to the nearest end, and so on.

[0043] When the movable frame 207 drives the spraying device but has not yet started sandblasting the building stone, the rotating piece 219 is already in a vertical state. When the sandblasting is completed, the rotating piece 219 is still in a vertical state. The movable frame 207 continues to move forward to drive the rotating piece 219 to close.

[0044] As the movable frame 207 continues to move forward, the movable frame 207 will hit the right end of the transverse frame 208, driving the transverse frame 208 to slide to the right in the end rotating seat 205, thereby driving the lower movable frame 209 and the upper trapezoidal block 210 to slide to the right, thereby driving the lower trapezoidal block 211 and the descending rod 212 to descend along the lower guide column 213, and the downward pressure spring 214 is squeezed. Since the upper trapezoidal block 210 will continue to be located above the lower trapezoidal block 211, the downward pressure spring 214 remains in a squeezed state. The descending rod 212 will drive the distal column 215 and the proximal column 223 to descend, thereby driving the proximal rack 224 and the distal rack 216 to descend, so that when the movable frame 207 returns to the original path, the rotating gear 220 will not engage with the distal rack 216 and the proximal rack 224, the rotating piece 219 remains in a parallel state, and the switch cylinder 218 remains closed, so that the switch cylinder 218 will only flow out the sandblasting liquid when the movable frame 207 moves forward, and will not flow out the sandblasting liquid when the movable frame 207 moves back.

[0045] When the movable frame 207 returns to the initial position, it will contact the left end of the transverse frame 208, driving the transverse frame 208 to slide to the left in the end swivel seat 205, thereby driving the upper trapezoidal block 210 to leave the top of the lower trapezoidal block 211 and return to the initial position, and the downward pressure spring 214 rebounds, driving the descending rod 212 and the lower trapezoidal block 211 to rise, and the descending rod 212 also returns to the initial position, and the distal rack 216 and the proximal rack 224 also return to the initial height.

[0046] like Figure 7 , Figure 8 As shown, the spraying device includes an up and down flip pipe 303 rotatably mounted on a movable frame 301, a spray gun 302 is fixedly mounted on the up and down flip pipe 303, a left and right rotating block 304 is rotatably mounted on the up and down flip pipe 303, a connecting rod 305 is fixedly mounted on the left and right rotating block 304, a rotating rod 306 is rotatably mounted on the connecting rod 305, a lower gear 308 is rotatably mounted on the movable frame 301, the rotating rod 306 is rotatably mounted with the movable frame 301, an upper gear 307 is fixedly mounted on the rotating rod 306, the upper gear 307 is meshed with the lower gear 308, a long rack 309 is fixedly mounted on the top plate 104, the long rack 309 is meshed with the lower gear 308, and the spray gun 302 is fixedly mounted with the upper spray pipe 221.

[0047] The sandblasting liquid in the lower pipe 222 is sprayed out through the spray gun 302. During the sliding process of the movable frame 207, the lower gear 308 and the upper gear 307 are driven to rotate through the meshing of the lower gear 308 and the long rack 309, thereby driving the rotating rod 306 to rotate, thereby driving the upper and lower turning pipes 303 to continuously rotate around the movable frame 301 through the connecting rod 305, thereby driving the spray gun 302 to swing up and down, that is, the left and right rotating blocks 304 slide left and right while swinging up and down, thereby realizing comprehensive sandblasting of the building stone.

[0048] like Fig. 9 , Fig.10 As shown, the clamping device includes a pedal frame 411 rotatably mounted on the bottom ear plate 109, a lower pedal 412 is fixedly mounted on the pedal frame 411, a descending column 403 is slidably mounted in the inner sleeve 111, a trailer 402 is fixedly mounted on the top of the descending column 403, a building stone 413 is placed on the trailer 402, a lower push plate 410 is fixedly mounted on the descending column 403, a side column 405 is slidably mounted on the clamping frame 401, a side clamp 404 is fixedly mounted on the side column 405, a side spring 406 is arranged between the side column 405 and the clamping frame 401, a side blocking frame 408 is rotatably mounted on the clamping frame 401, a side convex column 407 is fixedly mounted on the side blocking frame 408, the side convex column 407 slides and rotates in the waist hole of the side column 405, and a blocking ball 409 is fixedly mounted on the side blocking frame 408.

[0049] The building stone to be sandblasted is placed on the carriage 402. The gravity of the building stone 413 drives the carriage 402 and the descending column 403 to descend along the inner sleeve 111. The descending column 403 drives the pedal frame 411 to rotate, thereby hitting the blocking ball 409, thereby driving the blocking ball 409 to descend, thereby driving the side blocking frame 408 to rotate relative to the clamping frame 401, thereby driving the side column 405 and the side clamping piece 404 to slide inward through the side convex column 407, and the side spring 406 is squeezed, thereby clamping the building stone 413 through the side column 405. When the sandblasting of 413 is completed, the pedal 412 is stepped on, thereby driving the pedal frame 411 to rotate, thereby driving the descending column 403 and the carriage 402 to rise, and the side spring 406 rebounds, so that the side column 405 no longer clamps the building stone 413.

[0050] The working principle of a building stone sandblasting device disclosed in the present invention is: a building stone 413 to be sandblasted is placed on a trailer 402. Due to the gravity of the building stone 413, the trailer 402 and the descending column 403 are driven to descend along the inner sliding sleeve 111. The descending column 403 drives the pedal frame 411 to rotate, thereby hitting the blocking ball 409, thereby driving the blocking ball 409 to descend, thereby driving the side blocking frame 408 to rotate relative to the clamping frame 401, thereby driving the side column 405 and the side clamp 404 to slide inwardly through the side convex column 407, and the side spring 406 is squeezed, thereby clamping 413 through the side column 405. The liquid barrel 107 is filled with sandblasting liquid, that is, water mixed with sandblasting particles. The liquid barrel 107 outputs the sandblasting liquid to the spraying device, and the building stone 413 is sandblasted by the spraying device. After the sandblasting is completed, the sandblasting water flows through the slope of the inner slope plate 105 to the return liquid pipe 110, and the sandblasting waste water returns to the liquid barrel 107 through the return liquid pipe 110. The motor 201 rotates to drive the motor wheel 202 to rotate, thereby driving the screw wheel 204 and the bidirectional screw 206 to rotate through the transmission belt 203, thereby driving the movable frame 207 to slide along the top plate 104. In the initial state, the switch cylinder 218 is in a closed state, that is, the rotating piece 219 is in a horizontal state. When the movable frame 207 moves, since the proximal rack 224 is engaged with the rotating gear 220, the proximal rack 224 will drive the rotating gear 220 and the rotating piece 219 to rotate. When the rotating gear 220 is disengaged from the proximal rack 224, the rotating piece 219 and the rotating gear 220 just rotate ninety degrees. At this time, the rotating piece 219 is in a vertical state, and the sandblasting liquid in the liquid barrel 107 enters the upper nozzle 221 through the lower pipe 222 and is finally sprayed out through sandblasting. At the same time, in conjunction with the sliding of the movable frame 207, the spraying device is driven to sandblast the building stone. When the rotating gear 220 begins to mesh with the distal rack 216, the distal rack 216 will drive the rotating gear 220 and the rotating piece 219 to rotate. When the rotating gear 220 is disengaged from the distal rack 216, the rotating gear 220 and the rotating piece 219 rotate ninety degrees. At this time, the rotating piece 219 is in a parallel state, and the switch cylinder 218 is closed. The sandblasting liquid in the lower pipe 222 is sprayed out through the spray gun 302. During the sliding process of the movable frame 207, the lower gear 308 and the upper gear 307 are driven to rotate through the meshing of the lower gear 308 and the long rack 309, thereby driving the rotating rod 306 to rotate, thereby driving the upper and lower turning pipes 303 to continuously rotate around the movable frame 301 through the connecting rod 305, thereby driving the spray gun 302 to swing up and down, that is, the left and right rotating blocks 304 slide left and right while swinging up and down, thereby achieving comprehensive sandblasting of the building stone 413. When the movable frame 207 drives the spraying device but has not yet started sandblasting the building stone 413, the rotating piece 219 is already in a vertical state. When the sandblasting is completely completed, the rotating piece 219 is still in a vertical state. The movable frame 207 continues to move forward to drive the rotating piece 219 to close.As the movable frame 207 continues to move forward, the movable frame 207 will hit the right end of the transverse frame 208, driving the transverse frame 208 to slide to the right in the end rotating seat 205, thereby driving the lower movable frame 209 and the upper trapezoidal block 210 to slide to the right, thereby driving the lower trapezoidal block 211 and the descending rod 212 to descend along the lower guide column 213, and the downward pressure spring 214 is squeezed. Since the upper trapezoidal block 210 will continue to be located above the lower trapezoidal block 211, the downward pressure spring 214 remains in a squeezed state. The descending rod 212 will drive the distal column 215 and the proximal column 223 to descend, thereby driving the proximal rack 224 and the distal rack 216 to descend, so that when the movable frame 207 returns to the original path, the rotating gear 220 will not engage with the distal rack 216 and the proximal rack 224, the rotating piece 219 remains in a parallel state, and the switch cylinder 218 remains closed, so that the switch cylinder 218 will only flow out the sandblasting liquid when the movable frame 207 moves forward, and will not flow out the sandblasting liquid when the movable frame 207 moves back. When the movable frame 207 returns to the initial position, it will contact the left end of the traverse frame 208, driving the traverse frame 208 to slide to the left in the end rotating seat 205, thereby driving the upper trapezoidal block 210 to leave the lower trapezoidal block 211 and return to the initial position, and the downward spring 214 rebounds, driving the descending rod 212 and the lower trapezoidal block 211 to rise, and the descending rod 212 also returns to the initial position, and the distal rack 216 and the proximal rack 224 also return to the initial height. When the sandblasting 413 is completed, the pedal 412 is stepped on, thereby driving the tread frame 411 to rotate, thereby driving the descending column 403 and the drag frame 402 to rise, and the side spring 406 rebounds, so that the side column 405 no longer clamps the building stone 413.
