Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, and in particular relates to spray dust reduction equipment for a backhoe excavator. Background Art

[0002] Backhoe excavator is the most widely used earth-moving excavation machinery in engineering construction. It has the characteristics of flexible operation and fast rotation speed. It is mainly used for excavation of foundation pits (trenches) or pipe trenches below the working surface, independent foundation pits and slopes; straight line and curve excavation, excavation at a certain angle, ultra-deep trench excavation and trench slope excavation, etc. It is an excavator that is our most common excavation equipment. Because the backhoe excavator is flexible to operate, suitable for a variety of operations, and has low requirements for the working environment, the dust generated during the operation is difficult to handle.

[0003] A document with publication number (CN220644411U) was retrieved and disclosed a spray dust reduction device for a backhoe excavator, comprising a bucket arm, a water tank and a fixed frame. The bottom end of the bucket arm is hinged with a bucket, an embedding groove is provided on the outer wall of the water tank, and the water tank is embedded and installed on the outer wall of the bucket arm through the embedding groove. The outer wall of the fixed frame is fixedly connected to a water collecting pipe, and the outer wall of the water collecting pipe is provided with a plurality of atomizing nozzles for spray dust reduction.

[0004] The above-mentioned device is equipped with a booster water pump, a water suction pipe, a valve, a water pipe, a fixed frame, a water collecting pipe and an atomizing nozzle. During excavation operations, the driver can start the booster water pump through a remote control switch in the cab. Water is sprayed from the nozzle, which can produce water mist near the bucket to reduce dust generated during the excavator operation.

[0005] The above device uses a fixed atomizing nozzle to reduce dust on the bucket, but the position of the atomizing nozzle is fixed, which limits the spraying range and can only reduce dust at the spraying position. However, in actual work, the dust generated by the bucket is not limited to the bucket, and a large amount of dust will also be brought up at the working position, so the dust reduction range of the above device is limited.

[0006] In view of this, the present utility model is proposed. Utility Model Content
