Description

Technical Field

[0001] The utility model relates to the technical field of bucket tooth processing, in particular to a drilling machine used for processing bucket teeth of excavators. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the supporting surface and load them into a transport vehicle or unload them to a stockpile. When the bucket teeth and the excavator head are installed, they need to be locked and fixed by bolts passing through the connecting holes in the bucket teeth. Therefore, the surface of the bucket teeth needs to be drilled by a drilling machine.

[0003] For example, a drilling machine for processing bucket teeth of excavators disclosed in publication number CN219632655U positions the bucket teeth to the left and right by pressing the inner wall of the bucket teeth with the inner clamping plates, and the distance between the inner clamping plates is adjustable to accommodate excavation teeth of different widths. By opening the first hydraulic rod and the cylinder, the front clamping plates and the rear clamping plates form a front and rear clamp for the bucket teeth, and can accommodate bucket teeth of different lengths for drilling.

[0004] However, the practicality of the drilling device is poor when in use. Since drilling is required at both ends of the bucket tooth, the user needs to disassemble and fix the bucket tooth again after drilling one end of the bucket tooth, which leads to poor work efficiency. In addition, a lot of waste chips will remain on the surface of the bucket tooth when drilling, which cannot be automatically cleaned and needs to be cleaned manually afterwards, which is inconvenient. In view of this, we propose a drilling machine for excavator bucket tooth processing. Utility Model Content
