Description
Technical field
The utility model relates to metal stone ore exploitation engineering apparatus field, is especially a kind ofly used in the coring bit that ore rock stratum drills through.
Background technology
Now, in the time of mining, analyze rock stratum time, drill through rock core analysis by coring bit, the coring bit that many installations of the front ends at power tools such as electric hammer drills have adamantine core carries out. Diamond core bit the edge part segmentation of the front end of cylindrical body dispose multiple diamond blades. After the such diamond core bit of use is bored a hole operation, due to the residual cutting object in the inside at coring bit, thereby in the situation that carrying out next one perforation operation, must after being taken out, the core that residues in coring bit inside carry out. But in the perforate operation of concrete, stone material etc., even if wish is taken out residual core from front open side, also have situation about cannot take out swimmingly more, coring bit can be taken off and coring bit that core is taken out from bar portion thereby realized. This structure is the structure that via bar portion, coring bit is installed on to power tool, in the case of such coring bit combination, in order to take out core, make coring bit and bar part from, utilize bar-like member to squeeze out residual core from the hole of the rear end side (bar portion side) of coring bit, can take out thus core.
But, because coring bit and bar portion are in the past that screw thread is fixing, as shown in Figure 1, coring bit 20 is threaded with shank 10, so fixedly secure in perforation operation, need suitable labour and the situation of time and coring bit and bar portion are had after perforation operation. In order to solve this shortcoming, in recent years, propose can separate with once-through operation the installation constitution of coring bit and bar portion, because bar portion and holding pin are not one, so in the case of the perforation operation of lifting upward tool body and so on, holding pin moves to axial below, produces loosening problem, and can cause the deterioration of noise, vibration thereby have between the flange part of bar portion and core main body.
Therefore, the problems referred to above being necessary to propose relevant technologies improves.
Utility model content
For above-mentioned the deficiencies in the prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, and easy for installation is used in the coring bit that ore rock stratum drills through.
To achieve these goals, the utility model adopts following technical scheme:
A kind ofly be used in the coring bit that ore rock stratum drills through, it comprises shank and the coring bit cylindraceous of cylindrical tube shape, described shank upper end is provided with the first flange, described coring bit lower end is provided with the second flange with the corresponding connection of the first flange, described the first flange circumference portion is provided with four the first pin-and-holes around coring bit central shaft annular spread, described the second flange circumference portion is provided with second pin-and-hole corresponding with each the first described pin-and-hole, and described the first pin-and-hole is connected with the second pin-and-hole by pivot pin and coring bit and shank are connected as one.
Preferably, described coring bit upper surface circumferential part is connected with several blades for cutting.
Preferably, each described blade bottom is provided with the 3rd flange, and described coring bit upper surface edge side is provided with four flange corresponding with the 3rd flange.
Preferably, described the 3rd flange and the 4th flange are respectively arranged with the 3rd pin-and-hole and the 4th pin-and-hole, described the 3rd pin-and-hole be connected and blade be fixed on coring bit with the 4th pin-and-hole by the second pivot pin.
Owing to adopting technique scheme, the utility model the utility model coring bit is connected with shank by pivot pin, facilitate the replacing of coring bit, also utilized pivot pin to be fixed on coring bit at blade in addition, as each blade has damaged, directly change a blade, save so to a certain extent cost and increased work efficiency, strengthen bonding strength, there is very strong practicality simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, a kind ofly be used in the coring bit that ore rock stratum drills through, it comprises shank 100 and the coring bit cylindraceous 200 of cylindrical tube shape, shank 100 upper ends are provided with the first flange 110, coring bit 200 lower ends are provided with the second flange 210 with the first flange 110 corresponding connections, the first flange 110 circumferential parts are provided with four the first pin-and-holes 310 around coring bit central shaft annular spread, the second flange 210 circumferential parts are provided with second pin-and-hole 313 corresponding with each the first pin-and-hole 310, the first pin-and-hole 310 is connected with the second pin-and-hole 313 by the first pivot pin 300 and coring bit 200 and shank 100 is connected as one, coring bit 200 is connected with shank 100 by the first pivot pin 300, facilitate replacing and the installation of coring bit 200.
Further, on coring bit, 200 end face circumferential parts are connected with several blades 230 for cutting, and blade 230 is for cutting rock stratum.
Further, each blade 230 bottoms are provided with the 3rd flange 211, coring bit 200 upper surface edge sides are provided with four flange 111 corresponding with the 3rd flange 211, the 3rd flange 211 and the 4th flange 111 are respectively arranged with the 3rd pin-and-hole 311 and the 4th pin-and-hole 312, and wherein the 3rd pin-and-hole 311 is connected with the 4th pin-and-hole 312 with by the second pivot pin 321 and blade 230 is fixed on coring bit 200. Because ore rock stratum is harder, the long-time cutting of drill bit easily damages blade 230, because blade 230 is connected on coring bit 200 by the second pivot pin, be easy to change, to have damaged direct replacing just passable for blade 230, the production cost reducing so to a certain extent and increasing work efficiency.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
