Description
Technical Field
[0001] This utility model relates to the field of wall grinding technology, specifically to a wall grinding device with dust suppression function. Background Technology
[0002] A residential wall sanding device is a specialized tool or equipment used to sand the surface of residential walls. The main purpose of this device is to improve the flatness and smoothness of the walls, providing a good foundation for subsequent painting or wallpapering work.
[0003] Existing wall sanding equipment lacks dust suppression capabilities, causing dust generated during the sanding process to disperse into the air, posing a health hazard. The dust also negatively impacts the working environment, such as impairing visibility or increasing the likelihood of equipment malfunctions, thus significantly affecting construction efficiency. Furthermore, because the sanding mechanism is located above the base, existing wall sanding equipment cannot sand walls below the level above the base. This inability to directly sand these areas forces operators to use other methods, such as manually holding the sanding tool, to complete the sanding work. This not only increases the intensity of manual labor but may also affect the uniformity and efficiency of the sanding process.
[0004] Therefore, there is an urgent need for a wall sanding device with dust suppression function to solve the problem of poor dust suppression effect of existing wall sanding devices. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing a wall sanding device with dust suppression function, thereby solving the problem of poor dust suppression effect of existing wall sanding devices.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wall sanding device with dust suppression function is characterized by comprising a base, a vertical plate, a housing, a dust collection box, and a vertical moving mechanism. The vertical plate is located at the upper end of the base. The housing is connected to the vertical plate via the vertical moving mechanism, which drives the housing to move vertically up and down. A cavity is formed on the side wall of the housing away from the vertical plate. A drive motor is provided on the housing. The output end of the drive motor extends into the cavity and is connected to a grinding disc. The grinding disc is used to contact and sand the wall. A rubber pad is provided at the opening of the cavity. The dust collection box is located at the upper end of the base and is used to connect the cavity of the housing for dust collection.
[0008] To optimize the above technical solution, the specific measures also include:
[0009] Furthermore, the vertical moving mechanism includes a screw, a servo motor, and a movable plate. The vertical plate has a vertical groove near the side wall of the housing. The screw is vertically rotatably connected inside the groove. The movable plate is also slidably installed inside the groove. The movable plate is threadedly connected to the screw and connected to the side wall of the housing. A servo motor for driving the screw to rotate and moving the housing up and down is installed at the upper end of the vertical plate.
[0010] Furthermore, a motor is installed inside the movable plate, which is used to connect to the bottom of the box and drive the box to rotate.
[0011] Furthermore, the output end of the motor is fixedly connected to a main gear, which is rotatably disposed inside the movable plate. Inside the movable plate, there is also a gear that meshes with the main gear. One end of the gear is connected to a column, which rotatably extends out of the movable plate and is connected to the side wall of the housing.
[0012] Furthermore, two vertical rods are fixedly connected inside the chute, and the two vertical rods are respectively slidably connected through the movable plate.
[0013] Furthermore, a plate frame is detachably and slidably connected to one side wall of the dust collection box. A filter screen is provided in the middle of the plate frame inside the dust collection box. An air pump is provided at the bottom of the dust collection box and below the plate frame. An air inlet is provided on the side wall of the dust collection box above the plate frame. The air inlet is connected to the cavity of the box body through a connecting pipe.
[0014] Furthermore, a slot is provided at the bottom of the cavity, and the lower end of the slot is connected to the interior of the vacuum box through the connecting pipe.
[0015] Furthermore, the grinding disc is provided in three parts, and a main gear II and two gear II meshing with it are rotatably arranged inside the side wall of the housing. The main gear II is fixedly connected to the output end of the drive motor, and the ends of the three grinding discs are respectively fixedly connected to the side walls of the main gear II and the two gear II.
[0016] Furthermore, the lower end of the base is provided with multiple casters arranged in a rectangular array.
[0017] Furthermore, a push rod is fixedly connected to the upper end of the base.
[0018] The beneficial effects of this utility model are:
[0019] In use, the rubber pad at the opening of the side wall of the housing contacts and adheres to the wall, while the side wall of the grinding disc adheres to the side wall of the wall. The grinding disc is driven by a drive motor to rotate and grind the wall. During the grinding process, the rubber pad prevents the dust generated from grinding the wall from spreading inside the housing and into the outside. The dust collection box provides suction airflow to the inside of the housing, which not only absorbs and collects the dust but also further prevents dust from escaping. This avoids the dust from grinding the wall from being dispersed into the air and causing harm to the human body. At the same time, the reduction of dust not only protects the health of construction workers but also improves the working environment at the construction site. Cleaner air and a less dusty environment help improve construction efficiency and reduce blurred vision and equipment failure caused by dust.
[0020] When this utility model is in use, after the upper part of the wall is sanded, the box is at a certain height. The box can be rotated half a turn by the motor, so that the original upper part of the box is rotated to the lower part. Then, the movable plate drives the box to slide down. In this way, the adjusted grinding disc can sand the wall surface below the upper level of the base until the lower part of the box contacts the ground. This makes it easier to sand the wall below the upper level of the base, avoiding the situation where there are unsanded dead corners in the wall below the upper level of the base that require manual sanding. This achieves the effect of facilitating the vertical and comprehensive sanding of the wall.
[0021] In use, the suction airflow inside the dust collection box draws air into the cavity through the connecting pipe. The dust inside the cavity is guided by the suction airflow and moves into the dust collection box through the connecting pipe. The dust carried by the suction airflow is then filtered and collected by the filter screen. The air pump draws air into the dust collection box, thus generating suction airflow inside the dust collection box. Attached Figure Description

Detailed Implementation
[0028] The present invention will now be described in detail with reference to the accompanying drawings.
[0029] As attached Figure 1 As shown, a wall sanding device with dust suppression function according to an embodiment of the present invention includes a base 001, a vertical plate 002, a housing 003, a dust collection box 103, and a vertical moving mechanism. The vertical plate 002 is located on the upper end of the base 001. The housing 003 is connected to the vertical plate 002 through the vertical moving mechanism. The vertical moving mechanism is used to drive the housing 003 to move vertically up and down. A cavity 301 is opened on the side wall of the housing 003 away from the vertical plate 002. A drive motor 305 is provided on the housing 003. The output end of the drive motor 305 extends into the cavity 301 and is connected to a grinding disc 302. The grinding disc 302 is used to contact and sand the wall through the opening of the cavity 301. A rubber pad 303 is provided at the opening of the cavity 301. The dust collection box 103 is located on the upper end of the base 001 and is used to connect the cavity 301 of the housing 003 for dust collection.
[0030] In use, the rubber pad 303 at the opening on the side wall of the housing 003 contacts and adheres to the wall, while the side wall of the grinding disc 302 adheres to the side wall of the wall. The grinding disc 302 is driven by the drive motor 305 to rotate and grind the wall. During the grinding process, the rubber pad 303 prevents the dust generated from grinding the wall from spreading inside the cavity 301 and thus preventing it from spreading outside the housing 003. The dust collection box 103 provides suction airflow to the cavity 301, which not only absorbs and collects the dust but also further prevents dust from escaping. This avoids the dust from grinding the wall from drifting into the air and causing harm to the human body. At the same time, the reduction of dust not only protects the health of construction workers but also improves the working environment at the construction site. Clean air and a dust-free environment help improve construction efficiency and reduce blurred vision and equipment failure caused by dust.
[0031] In this embodiment, when vacuuming, the air intake requirement can be met through the gap between the rubber pad 303 and the wall, or an air intake hole can be opened on the housing 003 as needed, and a dustproof net can be installed on the air intake hole as needed.
[0032] As attached Figure 3 As shown in the further specific embodiment based on the above, the vertical moving mechanism includes a screw 202, a servo motor 203, and a movable plate 205. A vertical groove 201 is provided on the side wall of the vertical plate 202 near the housing 003. The screw 202 is vertically rotatably connected inside the groove 201. The movable plate 205 is also slidably installed inside the groove 201. The movable plate 205 is threadedly connected to the screw 202 and connected to the side wall of the housing 003. A servo motor 203 is installed at the upper end of the vertical plate 002 to drive the screw 202 to rotate and move the housing 003 up and down. In use, the servo motor 203 drives the screw 202 to rotate, causing the movable plate 205 to move the housing 003 up and down, allowing the grinding disc 302 to perform longitudinal grinding on the wall.
[0033] In a further specific embodiment based on the above, a motor 206 is installed inside the movable plate 205. The motor 206 is used to connect to the bottom of the housing 003 and drive the housing 003 to rotate. Thus, during use, after the upper part of the wall is sanded, the housing 003 is at a certain height. At this time, the motor 206 drives the housing 003 to rotate half a turn, rotating the original upper part of the housing 003 to the lower part. Then, the movable plate 205 drives the housing 003 to slide downwards. This allows the adjusted grinding disc 302 to sand the wall surface below the upper level of the base 001 until the lower part of the housing 003 contacts the ground. This facilitates sanding the wall below the upper level of the base, avoiding unsanded corners that require manual sanding, and achieving the effect of comprehensive longitudinal sanding of the wall.
[0034] As attached Figure 5 As shown, in a further specific embodiment based on the above, the output end of the motor 206 is fixedly connected to a main gear 207. The main gear 207 is rotatably disposed inside the movable plate 205. Inside the movable plate 205, a gear 209 that meshes with the main gear 207 is also rotatably disposed. One end of the gear 209 is connected to a column 208, which rotatably extends out of the movable plate 205 and is connected to the side wall of the housing 003. Specifically, the motor 206 drives the main gear 207 to rotate, and through the meshing between the main gear 207 and the gear 209, the gear 209 drives the column 208 to rotate. The column 208 drives the housing 003 to rotate half a circle, rotating the original upper end of the housing 003 to the lower end, and then grinding the wall surface below the horizontal level of the upper end of the base.
[0035] In a further specific embodiment based on the above, two vertical rods 204 are fixedly connected inside the slide groove 201, and the two vertical rods 204 are respectively slidably connected to the movable plate 205. In this way, the vertical rods 204 can guide and limit the longitudinally sliding movable plate 205.
[0036] In another specific embodiment based on the above, a frame 104 is detachably and slidably connected through one side wall of the dust collection box 103. A filter 105 is located in the middle of the frame 104 within the dust collection box 103. An air pump 106 is located at the bottom of the dust collection box 103, below the frame 104. An air inlet is located on the side wall of the dust collection box 103 above the frame 104, and the air inlet is connected to the cavity 301 of the box body 003 via a connecting pipe 107. In this embodiment, an exhaust port for connecting the air pump 106 is provided on the side wall of the dust collection box 103. The connecting pipe 107 is a flexible telescopic hose.
[0037] In use, the suction airflow inside the dust collection box 103 is used to draw in the interior of the cavity 301 through the connecting pipe 107. The dust inside the cavity 301 is guided by the suction airflow and moved into the dust collection box 103 through the connecting pipe 107. The dust carried by the suction airflow is then filtered and collected by the filter screen 105. The air pump 106 draws in the interior of the dust collection box 103, thus generating a suction airflow inside the dust collection box 103.
[0038] In a further specific embodiment based on the above, a funnel-shaped slot 304 is provided at the bottom of the cavity 301, and the lower end of the slot 304 is connected to the interior of the dust collection box 103 via a connecting pipe 107. Thus, the interior of the cavity 301 is suctioned through the connecting pipe 107 and the slot 304, and the dust inside the cavity 301 is guided by the suction airflow, moving through the slot 304 and the connecting pipe 107 to the interior of the dust collection box 103 for filtration and collection.
[0039] As attached Figure 4 As shown, in another specific embodiment based on the above, there are three grinding discs 302. A main gear 306 and two meshing gears 307 are rotatably mounted inside the side wall of the housing 003. The main gear 306 is fixedly connected to the output end of the drive motor 305. The ends of the three grinding discs 302 are respectively fixedly connected to the side walls of the main gear 306 and the two gears 307. Thus, the drive motor 305 drives the main gear 306 to rotate. When the main gear 306 rotates, it drives the two meshing gears 307 to rotate synchronously, and together they drive the three grinding discs 302 to rotate.
[0040] As attached Figure 2As shown, in another specific embodiment based on the above, the lower end of the base 001 is provided with a plurality of universal wheels 101 arranged in a rectangular array.
[0041] In another specific embodiment based on the above, a push rod 102 is fixedly connected to the upper end of the base 001. In use, the operator can manually push the push rod 102 to move the base 001 according to the multiple casters 101 and reach the designated position.
[0042] One specific embodiment of the device of this utility model is as follows:
[0043] The operator manually pushes the push rod 102 to move the base 001 to the designated position. At this time, the rubber pad 303 on the side wall of the housing 003 contacts and adheres to the wall, and the side wall of the grinding disc 302 adheres to the side wall of the wall. The drive motor 305 drives the second main gear 306 to rotate, and the second main gear 306 drives one of the grinding discs 302 to rotate. Through the meshing between the second gear 307 and the second main gear 306, the two gears 307 drive the other two grinding discs 302 to rotate. The rotation of the grinding discs 302 grinds the wall. The servo motor 203 drives the screw 202 to rotate, causing the movable plate 205 to drive the column 208 to slide upward. At the same time, the column 208 drives the housing 003 to move upward, so that the grinding discs 302 can grind the wall longitudinally.
[0044] During the sanding process of the grinding disc 302, the rubber pad 303 ensures that the dust generated during sanding is contained within the cavity 301 and does not spread to the outside of the housing 003. The air pump 106 draws air from the inside of the dust collection box 103, creating a suction airflow. This airflow is then drawn into the cavity 301 through the connecting pipe 107 and the slot 304. The dust inside the cavity 301 is guided by the suction airflow and moves through the slot 304 and the connecting pipe 107 into the dust collection box 103. The dust contained in the suction airflow is then filtered and collected by the filter screen 105, preventing the sanding dust from being dispersed into the air and causing harm to the human body.
[0045] After the upper part of the wall is polished, the box 003 is positioned at a certain height. The main gear 207 is driven to rotate by the motor 206. Then, through the meshing between the main gear 207 and the gear 209, the gear 209 drives the column 208 to rotate. The column 208 drives the box 003 to rotate half a circle, rotating the original upper part of the box 003 to the lower part. The movable plate 205 drives the box 003 to slide downward through the column 208. The grinding disc 302 polishes the wall surface below the upper level of the base 001 until the lower part of the box 003 contacts the ground. After the wall is polished, the box 003 rotates back to its original position in the original direction to avoid the continuous entanglement of the connecting pipe 107.
