Description

Technical Field

[0001] The invention relates to the technical field of mineral drilling equipment maintenance, in particular to a cleaning device for a geological drilling drill bit. Background Art

[0002] The geological drilling bit is a vital tool in geological exploration and mineral resource development. Its main function is to penetrate and break the strata through rotation and cutting. Among them, the most commonly used is the three-cone drill bit. The three-cone drill bit has the function of impacting, crushing and shearing the strata rocks when rotating, and can adapt to various soft, medium and hard strata. During the drilling process, the drill bit will come into contact with various stratum materials (soil, rock, gravel, etc.). These stratum materials are easy to adhere to the drill bit, forming sediments or scaling, which will affect the cutting efficiency and life of the drill bit, and is not conducive to the storage of the drill bit. The water spray structure attached to the drill bit during the drilling process generally acts on the ore rock surface on the front side of the cone along the drilling direction, mainly for the drilling and dust removal of the drill bit. It is not easy to eliminate the continuously compacted scaling and stuck stone particles in the gaps inside the cone. Usually, the staff needs to brush the drill bit to remove the sediments or scaling, protect the drill bit, and improve its service life and drilling efficiency.

[0003] In the prior art, the head of the three-cone drill bit is composed of three rotating cones arranged in a staggered manner, and the structure is relatively complex. The space inside the cones is narrow. The existing cleaning of the three-cone drill bit by spray gun can only rinse the surface, and it is difficult to fully clean the internal gaps and inner sides. Manual use of a brush to extend into the space inside the cone for cleaning is also difficult for workers to operate and inconvenient to clean due to the narrow space.

[0004] Chinese invention patent CN115874946A discloses a drill bit that is easy to clean. A cleaning block is used to disperse and clean rock cuttings and soil between three cones, which is beneficial to disperse the rock cuttings and soil that are difficult to clean between the three cones, and is convenient for quickly clearing the rock cuttings and soil mixed between the three cones from the drill bit, avoiding rock cuttings and soil mixed between the three cones. During the cleaning process, water can be sprayed from the end of the cleaning block through the guide groove to directly flush the rock cuttings in the four corners of the drill bit end, which is beneficial to quickly disperse the rock cuttings at the drill bit end and flush them away from the drill bit. Chinese invention patent CN117299632A discloses a cleaning device for a geological exploration drill bit. The threaded column is manually rotated through the lifting block and the connecting rod to drive the rotating track to rotate around the connecting block, so that the angle of the rotating track can be adjusted to form a curved track. The rotation of the threaded shaft drives the fixed rod, the L-shaped movable rod, the mounting plate and the two rotating wheels to move along the curved track with the cleaning brush. By designing the track as a curved track, it is convenient to clean the conical drill bit. However, the problem of cleaning and clearing the continuously compacted scale and stuck stone particles in the gaps inside the roller drill bit is not solved. Summary of the invention
