Fig. 2 is a schematic overall structure diagram of the embodiment of the present invention.

Fig. 3 is a schematic view of the overall structure of the floating support system.

The device comprises a frame 1, a movable main shaft system 2, a rubber roller conveying system 3, a floating type supporting system 4, a dust collecting system 5, a protective cover system 6, an upper pressing plate 7, a lower supporting plate 8, a pneumatic supporting system 9 and an adjusting device 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.

As shown in fig. 1-3, the present embodiment provides a floor slitting saw with a fast saw blade replacement, which includes a frame, a movable spindle system, a rubber roller conveying system, a floating support system, a dust collection system, and a protective cover system.

1. The frame is fixed on the ground and is used for providing mounting support for all other systems.

2. The movable main shaft system comprises a main driving motor, a main shaft, a saw blade and a guide rail sliding device. The main driving motor drives the main shaft to rotate through the elastic coupling, so that disconnection and connection can be conveniently carried out; the saw blade is arranged on the main shaft through a hydraulic lock sleeve or a key, and floors with different widths can be cut out through position adjustment; the guide rail sliding device comprises a bracket and a guide rail sliding block, the bracket is connected with the main shaft, and the guide rail sliding block is connected with the rack in a matching way.
