[0001] The invention relates to the technical field of drill bit equipment, in particular to a geological directional hole-reaming drill bit. Background Art

[0002] The geological directional hole expansion drill bit is a device used for geological exploration. This is mainly because the drill bit is small in size, but a larger drill bit is needed to expand the detection hole, so that the staff can more conveniently carry out the subsequent exploration work. With the development of science and technology, the geological directional hole expansion drill bit has developed to a great extent. Its development has brought great convenience to people when using the drill bit, and its types and quantities are also increasing day by day.

[0003] The geological directional reaming drill bits currently on the market have such a shortcoming that it is not convenient to increase the size of the drill bit on the device when the device is in use, so that the device cannot be used in detection environments in different occasions. Therefore, the current geological directional reaming drill bits need to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a geological directional reaming drill bit to solve the problem that the device proposed in the above background technology is not convenient to increase the size of the drill bit on the device when in use, so that the device cannot be used in detection environments in different occasions.

[0005] To achieve the above object, the present invention provides the following technical solution: a geological directional reaming drill bit, comprising a drill body, a cooling groove and a spring, wherein a slide rail is provided on the surface of the drill body, a slider is embedded in the interior of the slide rail, a fixing bolt is connected through the interior of the slider, a connecting block is provided on one side of the fixing bolt, and a protrusion is fixedly connected to the surface of the connecting block;

[0006] The cooling groove is opened inside the drill body, a sealing gasket is arranged at one end of the cooling groove, an outer wall of the sealing gasket is connected to a water injection port, one end of the water injection port is fixedly connected to the drill body, one end of the spring is fixedly connected to the drill body, one end of the spring is fixedly connected to a spring block, and a surface of the spring block is connected to the drill body.

[0007] As a further preferred technical solution, the main view of the slide rail is a "T"-shaped structure, and the size of the slide rail matches the outer wall size of the slider, and the slider forms a sliding connection structure with the drill body through the slide rail.

[0008] As a further preferred technical solution, there are two fixing bolts symmetrically distributed about the longitudinal center line of the connecting block and the slide rail, and a transversely penetrating mounting hole is opened inside the slider, and one end of the fixing bolt is transversely and vertically penetrates the mounting hole inside the slider and is connected to the drill body.

[0009] As a further preferred technical solution, one side surface of the connecting block is tangent to the surface of the drill body, and the top surface of the connecting block is an inclined structure, and the protrusions are distributed on the connecting block at equal intervals.

[0010] As a further preferred technical solution, the cross-section of the cooling groove is "L"-shaped, the sealing gasket is made of rubber, and the connection between the water injection port and the drill body is perpendicular to each other.

[0011] As a further preferred technical solution, the outer wall size of the spring block matches the inner wall size of the drill body, and a sliding connection structure is formed between the outer wall of the spring block and the inner wall of the drill body, and a sliding connection structure is formed between the spring block and the drill body through a spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The geological directional hole-reaming drill bit docks the slider connected to the connecting block with the slide rail, and pushes the slider to slide inside the slide rail. When one end of the slider fits against the inner wall of the drill body, the fixing bolt is docked with the mounting hole on the slider, thereby fixing the connecting block on the drill body, thereby increasing the hole-reaming diameter of the device.

[0014] 2. The geological directional reaming drill bit docks the corresponding device with the water injection port, and seals the connection between the corresponding device and the water injection port through a sealing gasket, and then injects coolant into the cooling tank through the water injection port. The coolant moves along the cooling tank until it comes out from another water injection port of the device, so that the device can be cooled more conveniently, thereby increasing the service life of the device.

[0015] 3. When the geological directional reaming drill is used, one end of the drill body is docked with the corresponding device. During the docking, the threads on the surface of the drill body and the corresponding device match each other, and the corresponding device squeezes the spring block to move toward one end of the spring, so that after the drill body is fixed, the spring block continues to squeeze the corresponding installation device through the action of the spring elasticity, thereby preventing the drill body from loosening.

A connecting block 5 is provided on one side of the fixed bolt 4, and two of the fixing bolts 4 are symmetrically distributed about the longitudinal midline of the connecting block 5 and the slide rail 2, and a transversely penetrating mounting hole is opened inside the slide block 3, and one end of the fixing bolt 4 is connected to the drill body 1 by vertically penetrating the mounting hole inside the slide block 3, so that the connecting block 5 can be fixed to the drill body 1 through the fixing bolt 4, and a protrusion 6 is fixedly connected to the surface of the connecting block 5, and one side surface of the connecting block 5 is tangent to the surface of the drill body 1, and the top surface of the connecting block 5 is an inclined structure, and the protrusions 6 are evenly spaced on the connecting block 5, so that the hole expansion size of the device can be increased through the connecting block 5.

[0024] The cooling groove 7 is opened inside the drill body 1, and a sealing gasket 8 is arranged at one end of the cooling groove 7. The cross-section of the cooling groove 7 is "L"-shaped, and the sealing gasket 8 is made of rubber material, and the connection between the water injection port 9 and the drill body 1 is perpendicular to each other, so as to facilitate lowering the temperature of the drill body 1 through the cooling groove 7, and the outer wall of the sealing gasket 8 is connected with the water injection port 9, and one end of the water injection port 9 is fixedly connected with the drill body 1, and one end of the spring 10 is fixedly connected with the drill body 1, and one end of the spring 10 is fixedly connected with the spring block 11, and the surface of the spring block 11 is connected with the drill body 1, and the outer wall size of the spring block 11 matches the inner wall size of the drill body 1, and the outer wall of the spring block 11 and the inner wall of the drill body 1 are in a sliding connection structure, and the spring block 11 forms a sliding connection structure with the drill body 1 through the spring 10, so as to facilitate preventing the drill body 1 from loosening through the spring block 11.
