Description

Technical Field

[0001] The utility model belongs to the technical field of milling machines, and in particular relates to a dust accumulation prevention device for milling machines. Background Art

[0002] At present, milling the damaged old pavement and laying a new surface layer is the most economical pavement maintenance method, and the milling machine is one of the main equipment for asphalt (concrete) pavement maintenance construction machinery. The milling machine is mainly used for excavation and renovation of roads, urban roads, airports, freight yards, etc. It can also be used to remove road bumps, oil waves, reticulation, rutting and other defects, and can also be used to excavate road potholes and grooves, as well as roughening and surface misalignment of cement roads.

[0003] In the process of milling the water-added concrete floor, the dust generated is very easy to condense into blocks, and these dust blocks will adhere to the inner side of the baffle. As the dust accumulates, the rotation resistance of the cutter shaft will gradually increase. When there is too much dust accumulation, the cutter shaft will stop, affecting the normal operation of the milling machine. For this reason, a device for preventing dust accumulation of a milling machine is proposed. Utility Model Content

[0004] The utility model aims to provide a dust accumulation prevention device for a milling machine, aiming to solve the problems raised in the above-mentioned background technology.

[0007] A dustproof gasket is installed on the mounting shaft and is located in the gap between the knife shaft and the inner side of the baffle plate, so as to reduce the accumulation of dust between the knife shaft and the inner side of the baffle plate.

[0008] Furthermore, clearance fit is adopted between adjacent dustproof gaskets.

[0009] Furthermore, the dustproof gasket and the knife shaft are clearance-fitted.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0018] like Figure 1-3 As shown, a dust accumulation prevention device for a milling machine provided by an embodiment of the utility model comprises:

[0019] The installation shaft 22 provides a support structure so that the dustproof gasket 21 can function in the correct position. The installation shaft 22 is installed on the milling machine cutter shaft frame 11, and the milling machine cutter shaft frame 11 is fixedly connected to the baffle 14, and the milling machine cutter shaft frame 11 is rotatably connected to the cutter shaft 12, and the cutter shaft 12 is fixedly connected to the blade 13;

[0020] The dustproof gasket 21 is mounted on the mounting shaft 22 and is located in the gap between the blade shaft 12 and the inner side of the baffle 14, and is used to reduce the accumulation of dust between the blade shaft 12 and the inner side of the baffle 14, thereby reducing the rotation resistance of the blade shaft 12 and preventing the blade shaft 12 from stopping due to excessive dust accumulation. A large clearance is used between adjacent dustproof gaskets 21 and between the dustproof gaskets 21 and the blade shaft 12. This design allows the dustproof gasket 21 to rotate flexibly and move left and right, thereby reducing the chance of dust condensation.

[0021] In the embodiment of the utility model, by installing the dust-prevention device of the milling machine between the cutter shaft 12 and the inner side of the baffle 14, the large clearance between the dust-proof gaskets 21 and the dust-proof gaskets 21 and the cutter shaft 12 can be used to flexibly rotate and move left and right. Such a design can not only prevent dust from condensing directly on the cutter shaft 12 and increase the rotation resistance, but also accelerate the falling of the condensed dust by soft collision when the dust accumulates and thickens to contact the blade 13, thereby keeping the cutter shaft 12 clean and running efficiently.

[0022] The working principle of the utility model is:

[0023] The dust-prevention device for the milling machine is installed between the cutter shaft 12 and the inner side of the baffle 14, and the large clearance between the dust-proof gaskets 21 and the cutter shaft 12 is used to flexibly rotate and move left and right. Such a design can not only prevent dust from condensing directly on the cutter shaft 12 and increase the rotation resistance, but also accelerate the falling of the condensed dust by soft collision when the dust accumulates and thickens to contact the blade 13, thereby keeping the cutter shaft 12 clean and running efficiently.

[0024] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
