Description

Technical Field

[0001] The present application relates to the technical field of dust prevention devices, and in particular to a dust prevention device for an excavator. Background Art

[0002] With the acceleration of urbanization and the increase in traffic demand, the scale of highway construction is expanding. However, during highway construction, especially in earth excavation and material transportation, the use of excavators will inevitably generate a lot of dust, which will not only pollute the surrounding environment, but also affect air quality and human health. Therefore, it is necessary to set up dust prevention devices to prevent and control the dust generated by the excavator during work.

[0003] The prior art discloses an anti-dust device for an excavator bucket and a preparation method thereof, comprising a forearm, a bucket and a covering unit, wherein the bucket is hinged to the lower end of the forearm, the covering unit is located on the forearm, the covering unit comprises a sleeve rod, a telescopic rod and a cover plate, the rear edge of the cover plate is hinged to the forearm, the cover plate is located above the bucket, the rear end of the sleeve rod is hinged to the forearm, the rear end of the telescopic rod is limited to the sleeve rod, the telescopic rod and the sleeve rod are slidably connected, and the front end of the telescopic rod is hinged to the middle of the top surface of the cover plate; when in use, since the bucket is hinged to the forearm, The bucket can rotate in the direction approaching or away from the cover plate. When the bucket is shoveling soil, the bucket moves away from the cover plate 3, and a larger gap is formed between the bucket and the cover plate for the construction soil to enter the bucket. Then the bucket rotates in the direction approaching the cover plate. At this time, the cover plate can cover the construction soil in the bucket. When there is a lot of construction soil, the cover plate can be pushed up, and the length of the telescopic rod extending into the sleeve rod is increased, which will not affect the stacking of the construction soil in the bucket. The covering of the cover plate alleviates the dust phenomenon during the shoveling operation and reduces the impact on the surrounding environment.

[0004] With regard to the above-mentioned related technologies, a sliding connection is adopted between the telescopic rod and the sleeve rod. In actual use, due to the vibration and impact of the excavator, the sliding connection may become loose or damaged, worn or loose, causing the telescopic rod to be unable to stably extend and retract, thereby affecting the opening and closing effect of the cover plate, causing the cover plate to be unable to completely cover the space above the bucket, causing some dust to overflow from the edge, affecting the anti-dust effect of the excavator.
