Embodiment 1

[0029] Such as figure 1 , figure 2 , image 3 and Figure 4As shown, for a hard cement floor, the grinding disc of a motor-driven ground grinder that needs to be ground with a metal grinding block 5 includes an upper disc 1, a middle disc 2 and a chassis 3, and the chassis 3 The working surface is a single flat disk, the width of the working surface of the chassis 3 is more than 500 mm, the motor is a vertical axis direct drive motor, and the center of the upper disk 1 is fixedly connected to the output shaft 4 of the direct drive motor , the center of the middle plate 2 is fixedly connected to the upper plate 1, the center of the chassis 3 is fixed on the center plate 2, and the output shaft 4 of the vertical axis direct drive motor is The end face is provided with an upper plate bolt threaded hole 41, the upper plate 1 is in the shape of a two-step circular platform, and the center of the upper surface of the upper stepped circular platform is provided with an output sha...

Embodiment 2

[0032] Such as figure 1 , figure 2 , Figure 5 and Figure 6 As shown, for the grinding of the floor with a low degree of ground hardness, it is necessary to use resin grinding blocks or ceramic grinding blocks for grinding. The grinding disc of a motor-driven ground grinder includes upper disc 1, middle disc Disk 2 and chassis 3, the working surface of the chassis 3 is a single flat disk, the width of the working surface of the chassis 3 is more than 500mm, the motor is a vertical axis direct drive motor, and the center of the upper disk 1 is circumferentially It is fixedly connected to the output shaft 4 of the direct drive motor, the center of the middle plate 2 is fixedly connected to the upper plate 1, and the center of the chassis 3 is fixed to the center of the middle plate 2. The lower end surface of the output shaft 4 of the vertical axis direct drive motor is provided with an upper plate bolt threaded hole 41, the upper plate 1 is in the shape of a two-step circu...

Embodiment 3

[0035] Such as figure 1 , figure 2 , Figure 7 and Figure 8 As shown, for the ground that has been roughly ground, when only smooth grinding is required, it is necessary to use animal hair pads or felt grinding blocks for grinding. The grinding disc of a motor-driven ground grinder includes upper disc 1, middle disc Disk 2 and chassis 3, the working surface of the chassis 3 is a single flat disk, the width of the working surface of the chassis 3 is more than 500mm, the motor is a vertical axis direct drive motor, and the center of the upper disk 1 is circumferentially It is fixedly connected to the output shaft 4 of the direct drive motor, the center of the middle plate 2 is fixedly connected to the upper plate 1, and the center of the chassis 3 is fixed to the center of the middle plate 2. The lower end surface of the output shaft 4 of the vertical axis direct drive motor is provided with an upper plate bolt threaded hole 41, the upper plate 1 is in the shape of a two-st...

Abstract

The invention relates to a grinding disk of a ground grinding machine driven by a motor. The grinding disk of the ground grinding machine driven by the motor comprises a base disk. The work face of the base disk is an independent flat disk. The width of the work face of the base disk is larger than 500 mm. A motor is a vertical axis direct drive motor. The direct drive motor is directly or indirectly connected with the base disk. A fixing device is arranged on the lower surface of the base disk. The fixing device is fixedly provided with grinding blocks. Compared with the prior art, the grinding disk of the ground grinding machine driven by the motor has the following advantages that the grinding disk is of an independent type, and by changing the arrangement manner of the grinding blocks,and the size of the grinding work face can be freely set; the large-torque direct drive motor is used for driving, so that the torque is large; the ground surface is ground flatly; the grinding blocks can be disassembled, assembled and replaced, and overhauling is rapid and convenient; a middle disk and the base disk are connected through an elastic damping rubber ring, so that the starting torque is reduced, and a buffering function is achieved; installation grooves can adopt circumferential alternate or radial alternate arrangement, so that the installed grinding blocks compensate for one another, the number of the grinding blocks is reduced, and uniform and comprehensive grinding is guaranteed.

Description

technical field [0001] The invention relates to a ground grinding construction device, in particular to a grinding disc of a ground grinding machine driven by a motor. Background technique [0002] Since the invention of cement in the 18th century, grinders have been widely used in various construction sites as equipment for ground grinding. It can effectively grind terrazzo, concrete surfaces, epoxy mortar layers, and old epoxy floors. [0003] In the current building construction, more and more rely on the grinder, and the grinder mainly relies on the grinding disc to grind and level the ground to be processed. In the past, due to the limitation of the power of the motor, the grinding disc with a large plane could not be driven, and the diameter of the usual grinding disc did not exceed 200mm. However, in order to improve the efficiency, a combination of multiple groups of small grinding discs was often used, as disclosed in Chinese patent CN209273167U The grinding disc o...
