Abstract

Portable anti-skidding of the present invention puts coring bit, it is to install a conical hollow drill bit (Fig. 2) (including solid bit) on the basis of original cartridge type corer (Fig. 1) again additional, is combined into a compound drill bit (Fig. 3).Both are combined by a fixing hole and two chute connections, are realized the switching of function, are reached the purpose (Fig. 4) of convenient coring.

Description

Portable anti-skidding puts coring bit

Technical field：The invention belongs to geology energy exploration development and application field and scientific research.

Technical background：Current portable corer is by a tubular drill bit coring.But due to tubular drill bit It is it is difficult to fixed drilling, can swing on rock core or rock or drift about coring is started, makes coring slow, coring efficiency becomes Low, and cause consume gasoline or electric power and water, to environmental protection and economize on resources unfavorable.The present invention can solve this and be stranded Difficulty, realizes that coring operation is simple, improves coring efficiency and using water wisely and gasoline or electric energy, and realizes that relative clean is operated.

Content of the invention：The present invention is to install a conical hollow again additional to bore on the basis of original cartridge type corer (Fig. 1) Head (Fig. 2), is combined into a compound drill bit (Fig. 3).Both are combined by a fixing hole and two chute connections, real The switching of existing function.

Description of the drawings：Fig. 1 is tubular coring bit；Fig. 2 is conical hollow drill bit；Fig. 3 is combined drill；Fig. 4 is work Principle schematic；1- drilling pipes；2- chutes；3- bores tooth；4- tops fixing hole；5- lower fixing holes；6- conical hollow drill bits；7- is solid Rationed marketing；8- rock cores.

Specific embodiment：The device be traditional portable corer (Fig. 1) drilling pipe (1) be set with a taper sky Heart drill bit (Fig. 2).It is combined into one compound drill bit (Fig. 3).Both are by two fixing holes (4,5) and two chute (2) connections Combine, realize the switching of function.Conical hollow drill bit (Fig. 2) is placed on drilling pipe (1) most when starting and creeping into coring Front end, by conical hollow drill bit (Fig. 2) is rotated to lower fixing hole (5) position counterclockwise, with clip (6) cone Shape hollow boring bit (Fig. 2) is fixed.Now conical hollow drill bit (Fig. 2) sophisticated directly contact rock core or rock when coring is started Stone, can easily penetrate among rock core or rock, will not swing or slide.Drilling pipe Deng drilling to tubular corer (Fig. 1) (1) drilling to after 1-2 millimeters deeps stops drilling through fixation of the counterclockwise rotates steady pin (6) conical hollow drill bit (Fig. 2) Pin (6) is rotated in chute, and the past position for being pulled upward to top fixing hole (4)；Now conical hollow drill bit (Fig. 2) is no longer played Effect, drilling are completed by drilling pipe completely.Rock core (8) carry for drilling through realizes the purpose of coring in drilling pipe (Fig. 4).If rock Heart fracture is retained in drilling pipe (Fig. 4), can also pass through conical hollow drill bit (Fig. 2) and push downwards, the rock core (8) in drilling pipe Extrusion, realizes coring purpose.

Claims (2)

1. the technology of a conical hollow drill bit (including solid bit) is set with tubular drill bit.

2. by with the technology for determining hole and chute combination tubular drill bit and conical hollow drill bit (including solid bit).
