Description

Technical Field

[0001] The utility model relates to the technical field of decoration engineering, in particular to a wall surface grinding and dust removal device for engineering decoration. Background Art

[0002] For wall grinding in decoration projects, a lot of dust will be generated during the grinding process. The dust will easily spread and affect the processing environment, which is not conducive to the health of operators. In order to prevent dust from escaping, people have added an exhaust pipe on the edge of the grinding disc. During the grinding process, the exhaust pipe also uses negative pressure to suck away the generated dust. Since the exhaust pipe port is in a normally open state, when the grinding disc stops working, the dust in the pipe is easily sprayed out. How to avoid the secondary splashing of dust in the exhaust pipe is a problem that needs to be solved at present. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a wall surface grinding and dust removal device for engineering decoration.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In this embodiment, refer to Figure 1-3 A wall grinding and dust removal device for engineering decoration includes a carrier 1, bevel gear transmission components 2 are arranged on both sides of the inside of the carrier 1, and the bevel gear transmission components 2 on both sides maintain coaxial transmission through a transmission shaft 3, and mounting columns 5 are respectively arranged on both sides of the top of the carrier 1, and screw transmission mechanisms are arranged in the mounting columns 5. The screw transmission mechanisms on both sides are connected through a mounting frame 8, and a grinding disc 9 is arranged at the center of the mounting frame 8. A rotating disc is arranged at the center of the grinding disc 9, and a grinding sandpaper 10 is installed on the rotating disc.

[0024] As attached Figure 1 As shown, the bevel gear transmission assembly 2 includes two bevel gears in meshing relationship, one of which is arranged on the top wall of the inner cavity of the carrier 1, and the other is arranged on the side wall of the inner cavity of the carrier 1. The bevel gear transmission assemblies 2 on both sides maintain a symmetrical relationship, and the bevel gear transmission assemblies 2 on both sides are respectively located between the bevel gears on the side wall of the inner cavity of the carrier 1 to maintain transmission connection through the transmission shaft 3. In addition, a motor 4 for controlling the rotation of the transmission shaft 3 is arranged outside the carrier 1.

[0025] The screw transmission mechanism includes a screw rod 6 and a nut pair 7. The screw rod 6 is vertically arranged in the mounting column 5. The nut pair 7 is threadedly assembled on the screw rod 6. The lower end of the screw rod 6 maintains transmission cooperation with the corresponding bevel gear transmission assembly 2 located below.

[0026] By driving the motor 4, the bevel gear transmission assemblies 2 on both sides are controlled to transmit synchronously, and the screw rods 6 on both sides are controlled to rotate simultaneously, so that the height of the mounting frame 8 can be adjusted, and finally the grinding position of the grinding disc 9 can be controlled, corresponding to the grinding and dust removal of the wall. By adjusting the position of the grinding sandpaper 10, the grinding area of ​​the wall can be fully covered to ensure that all parts of the wall can be polished.

[0027] Combined with Figure 2 It can be seen that the surface of the grinding disc 9 is provided with a plurality of circumferentially distributed dust suction ports 11 around the outer circumference of the grinding sandpaper 10 , and the dust suction ports 11 are externally connected to a dust suction pipe.

[0028] Combined with Figure 3 It can be seen that the inner wall of the grinding disc 9 is slidably connected with an inner gear ring 12, and an opening and closing component is provided at the end of each dust suction port 11. Each opening and closing component maintains meshing transmission with the inner gear ring 12 through its own full gear 13.

[0029] The structure of the opening and closing component is specifically described as follows: the opening and closing component includes a plurality of guide blocks 14, a sliding ring 15 and a plurality of baffle plates 19 distributed in a ring shape. The sliding ring 15 is built into the guide block 14 and slides in a ring shape. The sliding ring 15 is concentric with the dust suction port 11 in the center. The baffle plates 19 are rotatably installed on the inner side of the sliding ring 15 through a fixed shaft 18 and are distributed circumferentially. The inner ends of the baffle plates 19 are assembled into a full circle and overlap the dust suction port 11. The outer ends of the baffle plates 19 are provided with teeth. The inner surface of the sliding ring 15 is provided with a plurality of groups of internal teeth 17 matched with the outer end teeth of each baffle plate 19. At the same time, the outer surface of the sliding ring 15 is provided with external teeth 16 matched with the full gear 13.

[0030] It should be noted that one of the full gears 13 is a driving component, and a power motor for driving the full gear 13 to rotate is arranged outside the grinding disc 9 .

[0031] The opening and closing of each dust suction port 11 can be controlled by the opening and closing component. The specific working principle is that when one of the full gears 13 rotates, on the one hand, the inner gear ring 12 on the outside of the full gear 13 will rotate synchronously, and thereby drive the remaining full gears 13 to rotate; on the other hand, the sliding ring 15 on the inside of the full gear 13 will also rotate synchronously, and through meshing transmission, control the multiple blocking plates 19 of a single opening and closing component to rotate at the same time, so that the opening and closing of a single dust suction port 11 can be achieved by changing the position of the blocking plate 19.

[0032] Since the multiple full gears 13 are synchronously meshed and driven through the inner gear ring 12 , the several opening and closing components will synchronously open the corresponding dust suction ports 11 or synchronously close the corresponding dust suction ports 11 .

[0033] The dust suction port 11 can be opened to cooperate with the use of sandpaper 10 to suck the dust on the wall in the grinding state. The dust suction port 11 can be closed to block the dust that has been sucked into the pipe, preventing the dust from being sprayed out from the dust suction port 11, thereby avoiding the secondary emission of dust.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
