Abstract
The utility model relates to a drilling bit for building construction, which comprises a main rod (20) which is provided with a water chamber (12), a mud fetching cylinder (11) and a drill nozzle (7). A radial cut opening (24), a hinge door (4) and a water tank (6) which is communicated with the water chamber (12) are arranged on a bottom plate (1) of the mud fetching cylinder (11). By the adoption of the structure, mud in construction holes can be pulled out of ground, and conveniently transported away in one step, which causes no pollution to surrounding environment. The utility model has the advantages of simple structure, convenient installation and operation, low energy consumption, high efficiency, no noise, no pollution, etc. The utility model can be broadly used in industry and civil buildings for pouring stakes, digging holes and excavating water wells.
Description
The utility model relates to the building operations drill bit, belongs to building piling, drilling machine technology.
The existing auger that is applied to building foundation engineering generally adopts the vibrating impacter mode to hole, and noise is big; Need not stop injecting water under high pressure in boring procedure, earth is broken into outside the pulpous state tap, and environment pollution is serious, the earth difficult; And vibrating impacter if need transfer to soil layer to vibrating impacter, needs very big lifting power when the soil layer depths, cause rope-broken accident easily.
It is little that the purpose of this utility model provides a kind of noise, can once pierce down to weathered layer, and the building operations drill bit that can once take out earth.
The utility model is achieved through the following technical solutions: a kind of building operations drill bit, the lower end of the mobile jib of band water cavity has to bore chews, characteristics are that the mud tube is got in the bottom of mobile jib, get on the base plate of mud tube the radially edge of a knife of having lifted up is arranged, radially there is the rotating loose-leaf door that is installed on base plate the inside by hinge in the place ahead of the edge of a knife, gets the water tank that the outside of mud tube end plate is communicated with the mobile jib water cavity in addition.
Adopted said structure, just can once be drawn out ground to the earth of construction in the hole and easily carrying walk, surrounding environment is not polluted, the utlity model has simple in structure, easy to install, power consumption less, efficient height, noiselessness, advantage such as pollution-free, be widely used in industry and the filling stake borehole on civilian construction basis and the excavation of well.
Fig. 1 is a base arrangement schematic diagram of the present utility model;
Fig. 2 is that the B-B of Fig. 1 is to view;
Fig. 3 is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, the bottom of the mobile jib 20 of band water cavity 12 is equipped with and is got mud tube 11, get the container that mud tube 11 is upward openings, the radially edge of a knife 24 of having lifted up is arranged on its base plate 1, there is the rotating loose-leaf door 4 that is installed on base plate 1 the inside by hinge 3 in the place ahead that is positioned at the edge of a knife 24; There is water tank base plate 2 outside of base plate 1, water tank base plate 2 and the wherein radial joint and the sealing of cylindrical circumferential seam of getting that mud tube end plate 1 is connected, another radial joint is a water tank delivery port 5, interior round all seams of water tank base plate 2 are communicated with water cavity 12 by the linked hole 8 on the mobile jib 20, thereby form water tank 6.
The lower end of mobile jib 20 has to bore chews 7, bores shaft shoulder tube 23 end faces of chewing 7 upper end and fixes a clamping ring 9, and the lower end of connecting rod 19 is connected with clamping ring 9, is installed on the mobile jib 20 interior plate washers of fixing 21 by locating pad 13 down in the middle of it.
Top, abutment sleeve 14 of connecting rod 19 outer suits of following locating pad 13, on the screw thread of the top of connecting rod 19 with the upper surface of abutment sleeve 14 setscrew nut 15 on having on the segment distance, the abutment sleeve 14 outer springs 16 that are with again, above last setscrew nut 15, be on the top screw thread of connecting rod 19 ring washer 18 to be arranged, the last end in contact of the following and spring 16 of ring washer 18, ring washer 18 usefulness nuts 17 are fixing.
When motor drives mobile jib 20 rotates, mobile jib 20 drives and gets mud tube 11, bore to chew and 7 rotate, at this moment, radially earth is cut in the effect of the edge of a knife 24, the earth that is cut open upwards changes upper plate 1 along the direction of hilt, the earth that loose-leaf door 4 is made progress is opened, earth is constantly got mud tube 11 along with entering of the edge of a knife 24 downwards and upwards, can not decommission downwards up to the weathered layer hilt again.Water in the water cavity 12 enter water tank 6 by the linked hole on the mobile jib 20 8, adjust the water yield at the mouth of a river 5, make earth lubricated and reduce the load of hilt.
When motor drives mobile jib 20 is set aside from ground when getting mud tube 11, the downward pressure of earth are closed loose-leaf door 4 downwards in the mud tube 11 owing to get, and the mud tube 11 of getting of sealed bottom holds up whole earth.At this moment, because the effect of abutment sleeve 14 and spring 16, connecting rod 19 is driven bore and chew 7 and form the space of certain distance with the lower end of mobile jib 20, brill is chewed steam vent 22 on the shaft shoulder tube 23 of 7 upper ends and is made in the wellhole and can not form vacuum, and mobile jib 20 will once be pulled out ground to the earth of getting in the mud tube 11 at an easy rate.
According to the needs of practice of construction, change the size of getting mud tube 11 side plates 10, dispose the motor of corresponding efficient, can realize the purpose of different-diameter construction drill.
