Detailed Description
The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.
The specific embodiment of the present invention is such: referring to fig. 1-5, a high-efficiency drill point of a hard alloy drill bit comprises a drill bit body 1 and a drill point 2 arranged at the end of the drill bit body 1, wherein an insertion hole 3 is formed in the bottom axis of the drill bit body 1, an insertion shaft 4 matched with the insertion hole 3 is arranged at the top of the drill point 2, a clamping portion 5 is arranged at the bottom of the insertion shaft 4, a clamping groove 6 matched with the clamping portion 5 is formed in the orifice of the insertion hole 3, a spring 7 is arranged at the top end of the insertion hole 3, connecting structures connected with the drill bit body 1 and the insertion shaft 4 are respectively arranged at two ends of the spring 7, a plurality of sampling grooves 8 are formed in the bottom end face of the drill bit body 1, a plurality of cutting wings 9 are arranged at the side portion of the drill point 2, and a positioning portion 10 matched with.
In the high-efficiency drill point of the hard alloy drill bit, the drill point 2 can be inserted into the insertion hole 3 through the insertion shaft 4, and then is circumferentially limited through the clamping of the clamping part 5 and the clamping groove 6; the spring 7 at the top end of the plug shaft 4 is connected with the internal structure of the drill bit body 1, and the axial position of the plug shaft 4 can be limited through the spring 7, so that the plug shaft 4 of the plug shaft 4 cannot slide out of the jack 3 of the drill bit body 1. Thereby realize 2 detachable of drill point and install on drill bit body 1, easy dismounting, easy operation, dismouting work takes time fewly, low in labor strength, work efficiency is high.
In the high-efficiency drill point of the hard alloy drill bit, the positioning part 10 of the cutting wing 9 is matched with the sampling groove 8, so that the drill point 2 can be further limited in the circumferential direction, and the drill point 2 and the drill bit body 1 are prevented from rotating relatively;
moreover, the sampling groove 8 at the bottom end of the drill bit body 1 can collect rock and soil samples; after the drill bit completes drilling at a certain depth, when the drill bit is lifted upwards, the spring 7 in the jack 3 extrudes the drill tip 2 to enable the drill tip 2 to slide downwards, the positioning part 10 of the drill tip 2 slides out of the sampling groove 8, at the moment, the drill bit rotates, the drill bit is operated to drill downwards, rock and soil samples can be collected into the sampling groove 8, and the samples can be compacted.
