[0002] In construction, floor grinding refers to the use of grinding discs to grind and polish the floor to achieve the required smoothness and texture. It is usually used for rough and uneven floors. In the actual construction process, in order to avoid random splashing of grinding dust, a dust removal device is used for dust suppression.

[0003] The basic dust removal device generally sprays water during the grinding process to avoid dust generation, and then concentrates on cleaning the settled dust and impurities. However, due to the different materials of the construction floor, the splash range of the waste chips generated by grinding is also different. The fixed spraying range is often not able to spray dust well, and there are certain limitations. In order to solve the above technical problems, we have designed a dust removal device for building floor grinding construction. Utility Model Content

[0020] See also Figure 1-Figure 5 , a dust removal device for grinding and constructing a building floor, comprising a mounting shell 1, a grinding disc 2 being movably mounted on the bottom of the inner cavity of the mounting shell 1, a water spray transmission assembly 3 being mounted on the top of the mounting shell 1, the water spray transmission assembly 3 comprising a water pump 301, a first branch pipe 302 and a second branch pipe 304 being mounted on the water outlet ends of the water pump 301, a detachable dust reduction assembly 4 being mounted on both sides of the top of the mounting shell 1, the detachable dust reduction assembly 4 comprising a mounting seat 401 and a hollow sleeve 409, a positioning rod 402 being fixedly connected to one side of the mounting seat 401, a fixing seat 410 being provided on the top fixing sleeve of the surface of the positioning rod 402, The hollow sleeve 409 is supported, and the front and rear sides of the inner cavity of the hollow sleeve 409 are connected with the transmission frame 405. By setting the transmission frame 405, it can be connected with the hollow sleeve 409 and meet the installation requirements of the porous plate 404. The bottom of the inner cavity of the transmission frame 405 is installed with a porous plate 404. By setting the porous plate 404, it can prevent the spray hole from guiding the transmission water. The left and right sides of the bottom of the transmission frame 405 are installed with blocks 403. The side opposite to the block 403 and the porous plate 404 is fixedly inlaid with a magnet 413. By setting the magnet 413, it can play the role of magnetic attraction installation in the installed state to prevent the block 403 from rotating at will.

[0021] See also Figure 1 and Figure 2 The bottom of the water pump 301 is connected to the top of the mounting shell 1 by bolts, and the water inlet end of the water pump 301 is connected to the external water source through a hose.

[0022] See also Figure 2 and Figure 3 The water outlet end of the water pump 301 is connected to the three-way valve 303, one end of the first branch pipe 302 and the second branch pipe 304 are both connected to the three-way valve 303, and the other ends of the first branch pipe 302 and the second branch pipe 304 are both connected to the inner cavity of the hollow sleeve 409. By setting the first branch pipe 302, the three-way valve 303 and the second branch pipe 304, the water flow can be branched from the three-way valve 303 and passed into the first branch pipe 302 and the second branch pipe 304 when the water pump 301 is in working state.

[0023] See also Figure 1 and Figure 3 The surface of the mounting seat 401 is fixedly connected to the top of the mounting shell 1. By setting the mounting seat 401, it can be connected to the positioning rod 402 and the mounting shell 1 to ensure the installation stability of the positioning rod 402. The top of the fixing seat 410 is fixedly connected with the guide rod 408 and the damping block 407 respectively.

[0024] See also Figure 3The surface of the hollow sleeve 409 is provided with a card slot 406 used in conjunction with the damping card block 407. By providing the card slot 406 and the damping card block 407, the installation friction of the hollow sleeve 409 can be increased in the installed state, thereby preventing the hollow sleeve 409 from moving up at will. The surface of the hollow sleeve 409 is in sliding contact with the connection between the guide rod 408. By providing the guide rod 408, the hollow sleeve 409 can be accurately and quickly installed on the fixing seat 410.

[0025] See also Figure 3 and Figure 4 The outer ring of the porous plate 404 is in sliding contact with the connection between the transmission frame 405 and is sealed, and the surface of the stopper 403 is in sliding contact with the surface of the porous plate 404.

[0026] See also Figure 4 and Figure 5 A groove 411 is provided at the bottom of the transmission frame 405. By setting the groove 411, the installation requirements of the positioning block 412 and the rotation space requirements of the stop block 403 can be met. The inner wall of the groove 411 is fixedly connected with the positioning block 412. By setting the stop block 403 and the positioning block 412, the stop block 403 can support the porous plate 404 in the installed state to prevent the porous plate 404 from falling. The surface of the positioning block 412 is movably connected to the stop block 403 through a damping bearing.

[0027] In actual application, the inner cavity of the hollow sleeve 409 is connected with a joint, and the joint and the first branch pipe 302 and the joint and the second branch pipe 304 are connected by socket connection or flange connection.

[0028] In actual application, the spray holes on the porous plate 404 can be set at an angle. When the spray holes are in an inclined state, the water flow will be sprayed out at an angle, and the overall spray range will be larger.

[0029] In actual application, the top of the grinding disc 2 is fixedly connected to the output end of the external motor, so that when the motor is in working state, the grinding disc 2 continuously rotates and contacts the floor to achieve the purpose of grinding.

[0030] When in use, all components are in the initial installation state. During the rotation and grinding process of the grinding disc 2, the water pump 301 is synchronously controlled to work, and the water is diverted and transmitted to the first branch pipe 302 and the second branch pipe 304 through the three-way valve 303, and flows through the hollow sleeve 409 and the transmission frame 405, and finally sprayed outward through the porous plate 404, completing the dust reduction treatment of the grinding waste. In actual application, in order to meet the requirements of different spraying dust reduction ranges, the stopper 403 can be rotated to retract into the groove 411, and the stopper 403 no longer contacts the porous plate 404. Then the porous plate 404 is moved down and removed, and the porous plate 404 with suitable spray holes is replaced and installed. The hollow sleeve 409 can also be moved up to separate from the damping block 407, and the transmission frame 405 and the porous plate 404 are replaced as a whole. The porous plate 404 and the transmission frame 405 with appropriate sizes and specifications can be selected to well meet various spraying requirements.

[0031] In summary: the construction dust removal device for grinding building floor, by setting a detachable dust reduction component 4, solves the problem that the basic dust removal device is often unable to perform good spraying dust reduction due to the different materials of the construction floor and the different splashing range of waste chips generated by grinding.
