Embodiment 1

[0020] see Figure 1~3 , in an embodiment of the present invention, a ground grinding and cleaning device for building construction includes a base plate 1, a grinding structure and a dust suction structure arranged on the base plate 1, and universal wheels 20 are symmetrically connected on both sides of the lower end of the base plate 1 The grinding structure is installed in the placement cover 2 in the middle of the upper end of the bottom plate 1, and is kept stable by the limit sleeve 12 fixed in the placement cover 2. The dust suction structure includes Dust collection tube 15, the upper end of the dust collection tube 15 is connected to the air inlet end of the air pump 19, and the lower end of the dust collection tube 15 is connected to the dust collection bucket 17 corresponding to the lower part of the grinding structure through the dust extraction pipe 16.

[0021] Both sides of the placement cover 2 are symmetrically rotated and connected to be provided with a threa...

Embodiment 2

[0026] see image 3 , in the embodiment of the present invention, a ground grinding and cleaning device for building construction, on the basis of embodiment 1, the inner wall of the limit sleeve 12 is also rotatably connected with a bearing ring 13, and the inner ring of the bearing ring 13 is fixedly connected A plurality of sets of limit wheels 14 are provided, and the limit wheels 14 are distributed in an annular array on the inner ring of the bearing ring 13 with the center of the bearing ring 13 as the origin, and the limit wheels 14 are all movably attached to the periphery of the rotating shaft 10 . Such a design can prevent the rotating shaft 10 from shaking by limiting the limit wheel 14 when the rotating shaft 10 rotates. It can ensure the accuracy of the grinding processing position, and the processing is more stable.

[0027] The working principle of the present invention is: during use, according to the required grinding height adjustment handle 6 drives the dri...

Abstract

The invention discloses a ground grinding and cleaning device of building construction. The ground grinding and cleaning device comprises a bottom plate, a grinding structure arranged on the bottom plate and a dust collection structure. The two sides of the lower end of the bottom plate are symmetrically connected with universal wheels. The grinding structure is mounted in a mounting cover in themiddle of the upper end of the bottom plate in a movable lifting manner and keeps stable through a limiting sleeve fixed in the mounting cover. The dust collection structure comprises a dust collecting barrel arranged around the periphery of the mounting cover. The gas inlet end of a gas pump is arranged at the upper end of the dust collecting barrel in a communicating manner. A dust collecting hopper corresponding to the lower portion of the grinding structure is arranged at the lower end of the dust collecting barrel in a communicating manner through a dust drawing pipe. Through the grindingstructure in the ground grinding and cleaning device, different machining heights can be used through adjustment, use is more flexible, a rotating shaft is prevented from shaking through limiting oflimiting wheels, stable lifting is guaranteed in the lifting process of the rotating shaft, and therefore it can be guaranteed that grinding positions are precise, and operation is more stable duringmachining; and smoke dust during grinding is filtered after being sucked, air is exhausted, dust can be effectively collected, and dust raise can be avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a ground grinding and cleaning device for building construction. Background technique [0002] In building construction, after the cement is applied and dried, the ground is often uneven due to various reasons. At this time, it is necessary to polish and smooth the ground. [0003] In the prior art, a hand-held grinding device is used for grinding, and the smoke and dust are relatively large, and the smoothness of the grinding is difficult to control. When some mechanically movable grinding devices are in use, because different grinding heights need to be adjusted, the length of the transmission structure is often elongated, the resistance during transmission is relatively large, and the stability of the transmission part is relatively poor. Contents of the invention [0004] The object of the present invention is to provide a ground grinding and cleaning device ...
