In this embodiment, the connecting sleeve is fixed on the turntable 1, the rotating rod is connected with the output shaft of the driving member 3, and it can be understood that the positional relationship between the connecting sleeve and the rotating rod in this embodiment is that the positional relationship between the connecting rod 4 and the rotating sleeve 5 in the above embodiment is replaced, and the technical effects in the above embodiment can be achieved as well.
The second aspect of the present invention provides a wet spraying machine, which comprises a chassis, a boom arranged on the chassis, and a milling device provided in any one of the above technical solutions, so that the wet spraying machine provided by the present invention has all the benefits of the milling device provided in any one of the above technical solutions.
The arm support can drive the milling device to move, so that the milling device is driven to move to a to-be-milled working position.
In the description of the present specification, the terms "connected," "mounted," "fixed," and the like are to be construed broadly, and "connected" may be, for example, a fixed connection, a detachable connection, or an integral connection, and may be directly connected or indirectly connected through an intermediary. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
In the description of the present specification, the terms "one embodiment," "some embodiments," "particular embodiments," and the like, mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
