Description
Technical Field
The utility model relates to a milling machine technical field, concretely relates to middle-size and small-size milling machine dust pelletizing system.
Background
At present, the environmental protection requirement and control on dust emission generated during road construction operation are increasingly strict, and the construction is allowed only after the requirement of an increasingly large construction range reaches the environmental protection requirement. A road milling machine is a device for milling and excavating damaged road surfaces, which generates and releases a large amount of dust during the operation. The pollution to the ecological environment does not meet the development requirements and trends of the social environment. The generation of dust cannot be avoided, and the only solution is to effectively restrain and eliminate the release link of dust pollution environment. At present, the method for reducing and removing the raised dust in construction is to arrange vehicle-mounted fog gun equipment at the periphery of a milling machine in operation and carry out follow-up reduction and removal on the raised dust. Because sometimes the operation space is not wide enough, fog gun car receives the space restriction can not arrange or follow, perhaps can not accurately drop the raise dust and remove, greatly reduced the dust fall effect.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-2, a dust removal system for a small and medium-sized milling machine comprises a dust hood 1, a fan and a water mist spraying device 6, wherein the dust hood 1 is arranged above a conveyor belt on the milling machine; the fan comprises a shell 2, a fan 3, a bearing seat assembly 4 and a driving motor 5, wherein the dust hood 1 is fixedly connected with the shell 2, the interior of the dust hood is communicated with the interior of the shell, the fan 3 is arranged in the shell 2 and is fixedly arranged on the shell 2 through the bearing seat assembly 4, and the fan 3 rotates through the driving device 5; the water mist spraying device 6 is arranged on the shell 2. The dust hood 1 is connected with a material throwing opening 7 of the milling machine in a sealing way, and one end of the shell 2 is provided with an ash material outlet 8, and the ash material outlet 8 is opposite to a belt of the conveyor. The water mist spraying device 6 comprises a water pipe 61 and a plurality of atomizing water sprinkling nozzles 62, and the plurality of atomizing water sprinkling nozzles 62 are arranged and can be independently opened to control the water amount according to the dust size. The atomizing water spray nozzle 62 is disposed in the housing 2 and located between the fan 2 and the ash discharge port. Be provided with a plurality of interfaces that induced drafts (not shown in the figure) on the suction hood 1, can increase the dust storage port in the position that needs extra dust absorption, improved the dust absorption and held the redundancy, wherein suction hood 1 is through an interface that induced drafts and milling machine's throwing material mouth 7 sealing connection, and other interfaces that induced drafts seal temporarily. Preferably, the driving motor 5 is a hydraulic variable motor, and the rotating speed of fan blades of the fan can be adjusted according to the dust amount, so that different adaptive air suction amounts are realized. One end of the shell 2 is provided with an ash discharge port 8, and the ash discharge port 8 is opposite to the conveyor belt.
