Description

Technical Field

[0001] The utility model relates to the technical field of building decoration sandblasting, and particularly relates to a sandblasting device for building decoration construction. Background Art

[0002] With the development of the building decoration industry, the requirements for construction efficiency and quality are constantly increasing. In building decoration construction, the sandblasting process, as a surface treatment technology, is widely used in aspects such as removing old coatings, cleaning metal surfaces, and increasing coating adhesion.

[0003] At present, most sandblasting devices on the market are fixed or hand-held. Although the sandblasting effect of fixed devices is stable, it is difficult to move and adjust the position, which is not suitable for the changeable construction site; although hand-held devices are easy to carry and operate, it is difficult to ensure the sandblasting force and uniformity, which is not conducive to improving the use efficiency, and long-term operation is likely to cause fatigue to the operator. In addition, there are also deficiencies in dust removal of existing sandblasting equipment. During the sandblasting process, a large amount of dust is often generated, and these dusts will pose a potential threat to the environment and the health of operators. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing sandblasting device is inconvenient to move, it is difficult to ensure the sandblasting uniformity, which is not conducive to improving the use efficiency, and there are deficiencies in dust removal. The utility model provides a sandblasting device for building decoration construction.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a sandblasting device for building decoration construction, including a bottom plate, universal wheels, a handle, a sand storage tank, a sandblasting assembly, two dust collection devices, a stirring device, and a controller. The bottom plate is horizontally arranged and is above the ground. The universal wheels are above the ground and are arranged below the bottom plate, and the top surface of the universal wheels is fixedly connected to the bottom surface of the bottom plate. The handle is above the bottom plate, and the bottom surface of the handle is fixedly connected to the top surface of the bottom plate. The sand storage tank is above the bottom plate, on the side of the handle, and the bottom surface of the sand storage tank is fixedly connected to the top surface of the bottom plate. The sandblasting assembly is above the bottom plate and is arranged on the side of the sand storage tank away from the handle. The two dust collection devices are oppositely arranged on both sides of the sandblasting assembly and are arranged on the side of the bottom plate. The stirring device is arranged on the sand storage tank. The controller is above the bottom plate, and the controller is fixedly connected to the top surface of the bottom plate. The controller is electrically connected to the sandblasting assembly, the two dust collection devices, and the stirring device.

[0006] The sand storage tank is filled with abrasives for sandblasting. When the operator needs to stir the abrasives to improve the usage efficiency, the operator controls the stirring device to start through the controller. After the stirring device starts, it begins to stir the abrasives in the sand storage tank. After stirring for a period of time, the abrasives in the sand storage tank gradually become uniform. Then the operator turns off the stirring device through the controller. The evenly stirred abrasives can significantly improve the sandblasting efficiency.

[0007] When the operator needs to move the device to the decorative materials laid on the ground for sandblasting, the operator can hold the handle and push the device, and the device can then be moved to the laid decorative materials through the universal wheels for sandblasting.

[0008] When it is necessary to use the device to sandblast the decorative materials laid on the ground, the operator controls the sandblasting component to start through the controller. After the sandblasting component starts, it extracts the abrasives from the sand storage tank and accelerates the abrasives to a high speed to form a high-speed abrasive flow. The high-speed abrasive flow is evenly sprayed from the sandblasting component onto the decorative materials laid on the ground, completing the sandblasting of the decorative materials laid on the ground.

[0009] During the process of sandblasting the decorative materials laid on the ground, a large amount of dust will be generated. At this time, the operator controls the dust collection device to start through the controller. After the dust collection device starts, it generates negative pressure and begins to suction the dust in the working area to prevent these dusts from posing a potential threat to the surrounding environment and the health of the operator.

[0010] Furthermore, the sandblasting component includes a sandblaster, a feed pipe, a transmission mechanism, a "U"-shaped connecting frame, a sandblasting head, and a discharge hose. The sandblaster is arranged on the side of the sand storage tank away from the handle and above the bottom plate. The bottom surface of the sandblaster is fixedly connected to the top surface of the bottom plate. The sandblaster is electrically connected to the controller. The feed pipe is horizontally arranged between the sand storage tank and the sandblaster. The sand inlet of the feed pipe is fixedly connected to the side of the sand storage tank and communicates with the inside of the sand storage tank. The sand outlet of the feed pipe is fixedly connected to and communicates with the sand inlet of the sandblaster. The transmission mechanism is arranged above the bottom plate and on the side of the sandblaster away from the feed pipe. The bottom surface of the transmission mechanism is fixedly connected to the top surface of the bottom plate. The transmission mechanism is electrically connected to the controller. The "U"-shaped connecting frame is arranged above the transmission mechanism and fixedly connected to the transmission mechanism. The sandblasting head is arranged between the grooves of the "U"-shaped connecting frame, facing the ground, and the sandblasting head is fixedly connected to the "U"-shaped connecting frame by bolts. The discharge hose is arranged between the sandblaster and the sandblasting head. The sand inlet of the discharge hose is fixedly connected to and communicates with the sand outlet of the sandblaster. The sand outlet of the discharge hose is fixedly connected to and communicates with the sand inlet of the sandblasting head.

[0011] When it is necessary to use this device to perform sandblasting on the decorative materials laid flat on the ground, the operator controls the sandblaster and the transmission mechanism to start through the controller. After the sandblaster starts, it extracts abrasive from the sand storage tank through the feed pipe and accelerates the extracted abrasive to a high speed to form a high-speed abrasive flow. The high-speed abrasive flow is transported to the sandblasting head through the discharge hose and is evenly sprayed from the sandblasting head onto the decorative materials laid flat on the ground. The transmission mechanism drives the sandblasting head to move horizontally, enabling the sandblasting head to automatically sandblast the horizontal area of the material to be processed. At this time, the operator can push the device forward through the handle, enabling the sandblasting head to perform sandblasting operations along the length direction of the material. When the entire surface of the material has been evenly sandblasted, the sandblasting of the decorative materials laid flat on the ground is completed.

[0012] Further, the transmission mechanism includes a cross plate, a transmission groove, a lead screw, a drive motor, and a slider. The cross plate is arranged above the bottom plate and is perpendicular to the longest side of the bottom plate. The bottom surface of the cross plate is fixedly connected to the top surface of the bottom plate. The transmission groove is arranged on the top surface of the cross plate, and the transmission groove communicates with the inside of the bottom plate. The lead screw is arranged inside the transmission groove, and the axis of the lead screw is arranged horizontally, parallel to the longest side of the cross plate. The lead screw is fixedly connected to the transmission groove through a bearing. The axis of the rotating shaft of the drive motor coincides with that of the lead screw. The drive motor is arranged on the side of the cross plate, and the side surface of the drive motor is fixedly connected to the side surface of the cross plate. The rotating shaft of the drive motor penetrates through the side of the cross plate and is fixedly connected to one end of the lead screw. The drive motor is electrically connected to the controller. The slider is sleeved on the lead screw and is arranged below the "U"-shaped connecting frame. The slider is threadedly connected to the lead screw, and the top surface of the slider is fixedly connected to the bottom surface of the "U"-shaped connecting frame.

[0013] When it is necessary for the sandblasting head to move horizontally automatically, the operator controls the drive motor to start through the controller. After the drive motor starts, its rotating shaft rotates and drives the lead screw to rotate. Since the slider is threadedly connected to the lead screw, the rotation of the lead screw causes the slider to move linearly along the lead screw. The slider drives the sandblasting head on the "U"-shaped connecting frame to move horizontally, enabling the sandblasting head to automatically sandblast the horizontal area of the material to be processed. The operator can control the drive motor to change the rotation direction through the controller to make the sandblasting head move horizontally back and forth, enabling the sandblasting head to spray the high-speed abrasive flow more evenly onto the horizontal area of the material to be processed.

[0014] Further, the dust collection device includes a dust collection box, a first conveying pipe, a suction fan, a second conveying pipe, and a dust suction hood. The dust collection box is arranged above the bottom plate and on the side of the discharge hose, and the bottom surface of the dust collection box is fixedly connected to the top surface of the bottom plate. The first conveying pipe is arranged on the side of the dust collection box, and the dust outlet of the first conveying pipe is fixedly connected to the side of the bottom plate and communicates with the inside of the bottom plate. The suction fan is arranged on the side of the bottom plate close to the dust collection box and on the side of the dust inlet of the first conveying pipe. The suction fan is fixedly connected to the side surface of the bottom plate, and the dust outlet of the suction fan is fixedly connected to and communicates with the dust inlet of the first conveying pipe. The suction fan is electrically connected to the controller. The dust outlet of the second conveying pipe is arranged on the side of the dust inlet of the suction fan, and the dust outlet of the second conveying pipe is fixedly connected to and communicates with the dust inlet of the suction fan. The dust suction hood is arranged vertically, the dust suction opening of the dust suction hood is arranged parallel to the longest side of the bottom plate, the dust suction openings of the two dust suction hoods are oppositely arranged inside the dust suction hood, the dust suction hood is arranged on the side of the bottom plate away from the handle, and the dust outlet of the dust suction hood is fixedly connected to and communicates with the dust inlet of the second conveying pipe.

[0015] When it is necessary to remove the dust generated during the sandblasting process of the decorative materials laid on the ground, the operator controls the suction fan to start through the controller. After the suction fan starts, a negative pressure is generated, and the dust in the sandblasting work area is sucked into the dust suction opening of the dust suction hood and conveyed to the suction fan through the second conveying pipe. The suction fan sprays the dust inside from its dust outlet and conveys it to the dust collection box through the first conveying pipe, completing the treatment of the dust generated during the sandblasting process of the decorative materials laid on the ground and preventing these dusts from posing a potential threat to the surrounding environment and the health of the operator.

[0016] Further, the stirring device includes a stirring motor, a stirring rod, and stirring blades. The stirring motor is arranged on the top of the sand storage tank. The axis of the rotating shaft of the stirring motor is arranged vertically. The bottom surface of the stirring motor is fixedly connected to the top surface of the sand storage tank. The rotating shaft of the stirring motor enters the inside of the sand storage tank through the top of the sand storage tank. The stirring motor is electrically connected to the controller. The stirring rod is arranged vertically and inside the sand storage tank. The axis of the stirring rod coincides with the axis of the rotating shaft of the stirring motor. The top end of the stirring rod is fixedly connected to the rotating shaft of the stirring motor. The stirring blades are arranged inside the sand storage tank. The stirring blades are sleeved on the stirring rod and fixedly connected to the stirring rod.

[0017] The stirring blades can effectively mix the abrasives in the sand storage tank, thereby providing a uniform supply of abrasives for the sandblasting operation, and improving the sandblasting quality and efficiency. When the operator needs to stir the abrasives, the operator controls the stirring motor to start through the controller. After the stirring motor starts, its rotating shaft rotates to drive the stirring rod to rotate. The stirring rod rotates to drive the stirring blades to rotate. The stirring blades rotate and agitate the abrasives in the sand storage tank, making the abrasives fully mixed. After stirring for a period of time, the abrasives in the sand storage tank are gradually mixed evenly. The operator turns off the stirring motor through the controller to complete the stirring of the abrasives in the sand storage tank.

[0018] Further, it includes a switch which is arranged on the handle, fixedly connected to the handle, and electrically connected to the controller.

[0019] The switch is arranged on the handle, which means that when the operator holds the handle to move the device, they can easily access the switch, thus more conveniently and safely controlling the controller, improving the efficiency and safety of the operation.

[0031] The sand storage tank 4 is filled with abrasives for sandblasting treatment. When an operator needs to stir the abrasives to improve the usage efficiency, the operator controls the stirring device to start through the controller 5. After the stirring device starts, it begins to stir the abrasives in the sand storage tank 4. After stirring for a period of time, the abrasives in the sand storage tank 4 gradually become uniform. The operator turns off the stirring device through the controller 5. The uniformly stirred abrasives can significantly improve the sandblasting efficiency.

[0032] When an operator needs to move the device to the decorative materials laid on the ground for sandblasting treatment, the operator can hold the handle 3 and push the device, and the device can then be moved to the laid decorative materials through the universal wheels 2 for sandblasting treatment.

[0033] When it is necessary to use the device to perform sandblasting treatment on the decorative materials laid on the ground, the operator controls the sandblasting assembly to start through the controller 5. After the sandblasting assembly starts, it extracts abrasives from the sand storage tank 4 and accelerates the abrasives to a high speed to form a high-speed abrasive flow. The high-speed abrasive flow is evenly sprayed from the sandblasting assembly onto the decorative materials laid on the ground to complete the sandblasting treatment of the decorative materials laid on the ground.

[0034] During the process of sandblasting treatment on the decorative materials laid on the ground, a large amount of dust will be generated. At this time, the operator controls the dust collection device to start through the controller 5. After the dust collection device starts, it generates negative pressure and begins to suck the dust in the working area to prevent these dusts from posing a potential threat to the surrounding environment and the health of the operator.

[0035] The sandblasting assembly includes a sandblasting machine 6, a feed pipe 7, a transmission mechanism, a "U"-shaped connecting frame 8, a sandblasting head 9, and a discharge hose 10.

The transmission mechanism is arranged above the bottom plate 1 and on the side of the sandblasting machine 6 away from the feed pipe 7. The bottom surface of the transmission mechanism is fixedly connected to the top surface of the bottom plate 1. The transmission mechanism is electrically connected to the controller 5. The "U"-shaped connecting frame 8 is arranged above the transmission mechanism and is fixedly connected to the transmission mechanism. The sandblasting head 9 is arranged between the grooves of the "U"-shaped connecting frame 8. The sandblasting head 9 is arranged facing the ground and is fixedly connected to the "U"-shaped connecting frame 8 by bolts. The discharge hose 10 is arranged between the sandblasting machine 6 and the sandblasting head 9. The sand inlet of the discharge hose 10 is fixedly connected to and communicates with the sand outlet of the sandblasting machine 6. The sand outlet of the discharge hose 10 is fixedly connected to and communicates with the sand inlet of the sandblasting head 9.

[0036] When it is necessary to use this device to perform sandblasting on the decorative materials laid flat on the ground, the operator controls the sandblasting machine 6 and the transmission mechanism to start through the controller 5. After the sandblasting machine 6 starts, it extracts abrasive from the sand storage tank 4 through the feed pipe 7 and accelerates the extracted abrasive to a high speed to form a high-speed abrasive flow. The high-speed abrasive flow is transported to the sandblasting head 9 through the discharge hose 10 and is evenly sprayed from the sandblasting head 9 onto the decorative materials laid flat on the ground. The transmission mechanism drives the sandblasting head 9 to move horizontally, enabling the sandblasting head 9 to automatically sandblast the lateral area of the material to be processed. At this time, the operator can push the device forward through the handle 3, enabling the sandblasting head 9 to perform sandblasting operations along the length direction of the material. When the entire surface of the material has been evenly sandblasted, the sandblasting of the decorative materials laid flat on the ground is completed.

[0037] The transmission mechanism includes a horizontal plate 11, a transmission groove, a lead screw 12, a drive motor 13, and a slider 14.

The drive motor 13 is arranged on the side of the horizontal plate 11, and the side surface of the drive motor 13 is fixedly connected to the side surface of the horizontal plate 11. The rotating shaft of the drive motor 13 penetrates the side of the horizontal plate 11 and is fixedly connected to one end of the lead screw 12. The drive motor 13 is electrically connected to the controller 5. The slider 14 is sleeved on the lead screw 12, arranged below the "U"-shaped connecting frame 8. The slider 14 is threadedly connected to the lead screw 12, and the top surface of the slider 14 is fixedly connected to the bottom surface of the "U"-shaped connecting frame 8.

[0038] When the sandblasting head 9 needs to move horizontally automatically, the operator controls the drive motor 13 to start through the controller 5. After the drive motor 13 starts, its rotating shaft rotates and drives the lead screw 12 to rotate. Since the slider 14 is threadedly connected to the lead screw 12, the rotation of the lead screw 12 causes the slider 14 to move linearly along the lead screw 12. The slider 14 drives the sandblasting head 9 on the "U"-shaped connecting frame 8 to move horizontally, enabling the sandblasting head 9 to automatically sandblast the horizontal area of the material to be processed. The operator can control the drive motor 13 to change the rotation direction through the controller 5 to make the sandblasting head 9 move horizontally back and forth, enabling the sandblasting head 9 to more evenly spray the high-speed abrasive flow onto the horizontal area of the material to be processed.

The dust suction hood 19 is arranged on the side of the bottom plate 1 away from the handle 3. The dust outlet of the dust suction hood 19 is fixedly connected to and communicates with the dust inlet of the second conveying pipe 18.

[0040] When it is necessary to remove the dust generated during the sandblasting process of the decorative materials laid flat on the ground, the operator controls the suction fan 17 to start through the controller 5. After the suction fan 17 starts, a negative pressure is generated, and the dust in the sandblasting work area is sucked into the dust suction opening of the dust suction hood 19 and conveyed to the suction fan 17 through the second conveying pipe 18. The suction fan 17 sprays the dust inside from its dust outlet and conveys it to the dust collection box 15 through the first conveying pipe 16, completing the treatment of the dust generated during the sandblasting process of the decorative materials laid flat on the ground and preventing these dusts from posing a potential threat to the surrounding environment and the health of the operator.

[0041] The stirring device includes a stirring motor 20, a stirring rod 21, and stirring blades 22. The stirring motor 20 is arranged on the top of the sand storage tank 4. The axis of the rotating shaft of the stirring motor 20 is arranged vertically. The bottom surface of the stirring motor 20 is fixedly connected to the top surface of the sand storage tank 4.

The stirring motor 20 is electrically connected to the controller 5. The stirring rod 21 is arranged vertically and inside the sand storage tank 4. The axis of the stirring rod 21 coincides with the axis of the rotating shaft of the stirring motor 20. The top end of the stirring rod 21 is fixedly connected to the rotating shaft of the stirring motor 20. The stirring blades 22 are arranged inside the sand storage tank 4. The stirring blades 22 are sleeved on the stirring rod 21 and fixedly connected to the stirring rod 21.

[0042] The stirring blade 22 can effectively mix the abrasive in the sand storage tank 4, thereby providing a uniform supply of abrasive for the sandblasting operation, and improving the sandblasting quality and efficiency. When the operator needs to stir the abrasive, the operator controls the stirring motor 20 to start through the controller 5. After the stirring motor 20 starts, its rotating shaft rotates to drive the stirring rod 21 to rotate, the stirring rod 21 rotates to drive the stirring blade 22 to rotate, and the stirring blade 22 rotates to agitate the abrasive in the sand storage tank 4, so that the abrasive is fully mixed. After stirring for a period of time, the abrasive in the sand storage tank 4 is gradually mixed evenly, and the operator turns off the stirring motor 20 through the controller 5 to complete the stirring of the abrasive in the sand storage tank 4.

[0043] It includes a switch 23, the switch 23 is arranged on the handle 3, the switch 23 is fixedly connected to the handle 3, and the switch 23 is electrically connected to the controller 5.

[0044] The switch 23 is arranged on the handle 3, which means that when the operator holds the handle 3 to move the device, the operator can easily access the switch 23, thereby controlling the controller 5 more conveniently and safely, and improving the efficiency and safety of the operation.

[0045] The working principle of the present utility model is as follows:

[0046] When the operator needs to stir the abrasive to improve the use efficiency, the operator controls the stirring motor 20 to start through the controller 5. After the stirring motor 20 starts, its rotating shaft rotates to drive the stirring rod 21 to rotate, the stirring rod 21 rotates to drive the stirring blade 22 to rotate, and the stirring blade 22 rotates to agitate the abrasive in the sand storage tank 4, so that the abrasive is fully mixed. After stirring for a period of time, the abrasive in the sand storage tank 4 is gradually mixed evenly, and the operator turns off the stirring motor 20 through the controller 5 to complete the stirring of the abrasive in the sand storage tank 4. The evenly stirred abrasive can significantly improve the sandblasting efficiency.

[0047] When the operator needs to move the device to the decorative material laid on the ground for sandblasting, the operator can hold the handle 3 and push the device, and the device can be moved to the laid decorative material for sandblasting through the universal wheels 2.

[0048] When it is necessary to use this device to perform sandblasting on the decorative materials laid flat on the ground, the operator controls the controller 5 to energize the sandblaster 6 and the drive motor 13 through the switch 23. After the sandblaster 6 is energized and started, it extracts abrasive from the sand storage tank 4 through the feed pipe 7 and accelerates the extracted abrasive to a high speed to form a high-speed abrasive flow. The high-speed abrasive flow is transported to the sandblasting head 9 through the discharge hose 10 and is evenly sprayed from the sandblasting head 9 onto the decorative materials laid flat on the ground. After the drive motor 13 is energized and started, its rotating shaft rotates and drives the lead screw 12 to rotate. Since the slider 14 is threadedly connected to the lead screw 12, the rotation of the lead screw 12 causes the slider 14 to move linearly along the lead screw 12. The slider 14 drives the sandblasting head 9 on the "U"-shaped connecting frame 8 to move horizontally, so that the sandblasting head 9 can automatically sandblast the lateral area of the material to be processed. At this time, the operator can push the device forward through the handle 3, so that the sandblasting head 9 can perform sandblasting operations along the length direction of the material. When the entire surface of the material has been evenly sandblasted, the sandblasting of the decorative materials laid flat on the ground is completed.

[0049] When it is necessary to remove the dust generated during the sandblasting process of the decorative materials laid flat on the ground, the operator controls the suction fan 17 to start through the controller 5. After the suction fan 17 starts, a negative pressure is generated, and the dust in the sandblasting work area is sucked into the dust suction port of the dust suction hood 19 and is transported to the suction fan 17 through the second conveying pipe 18. The suction fan 17 sprays the dust inside from its dust outlet and transports it to the dust collection box 15 through the first conveying pipe 16, completing the treatment of the dust generated during the sandblasting process of the decorative materials laid flat on the ground, and preventing these dusts from posing a potential threat to the surrounding environment and the health of the operator.
