[0024] The anchor hole forming drill bit provided by the utility model is now described.

[0025] like Figures 1 to 4 As shown, the first embodiment of the utility model provides an anchor hole drill bit, including a main body component 100 and a connecting component 200, which can cooperate to effectively seal the pipeline to prevent dust backflow from damaging the equipment, and the installation is simple and convenient, and the sealing between the devices is good.

[0026] The main body assembly 100 includes a threaded column 101 and a blocking member 102 . The blocking member 102 is disposed at the bottom of the threaded column 101 .

[0027] When rotating, the threaded column 101 can play a role of excavation, so that the threaded column 101 is in the shape of an inner hook, which is helpful for excavating rocks and digging soil. The blocking member 102 can effectively close the pipeline to prevent dust backflow from damaging the equipment.

[0028] The connection assembly 200 is disposed on the top of the threaded column 101 , and includes a connection frame 201 and a stopper 202 . The connection frame 201 is sleeved on the outside of the threaded column 101 , and the stopper 202 is located on the connection frame 201 .

[0029] A sealing ring is provided on the connection frame 201, which can ensure the sealing of the threaded column 101 when connected to the threaded column 101. The threaded column 101 can be docked with the device by using the connection frame 201 to facilitate docking. The limiting members 202 are two groups, which are respectively provided on both sides of the connection frame 201. The connection frame 201 can be limited by the setting of the limiting members 202 to prevent the connection frame 201 from falling off after the connection frame 201 is installed. Among them, the threaded column 101, the blocking member 102 and the connection frame 201 are all steel components.

[0030] like Figures 1 to 4 As shown, the utility model provides a specific implementation method based on the first implementation method as follows:

[0031] Specifically, the blocking member 102 includes a drill bit 102a and a chiseling plate 102b. The drill bit 102a is fixed to the bottom of the threaded column 101, and the chiseling plate 102b is arranged on one side of the drill bit 102a.

[0032] There are two chiseling plates 102b, which are respectively arranged on both sides of the drill bit 102a. When the threaded column 101 rotates, the two chiseling plates 102b and the drill bit 102a at the bottom can be used to chisel. The chiseling plates 102b are in the shape of inner hooks, and the chiseling plates 102b can help to chisel rocks and dig soil when rotating.

[0033] Specifically, the blocking member 102 further includes a support plate 102 c , which is disposed on one side of the excavating plate 102 b and is fixed to the bottom of the threaded column 101 .

[0034] There are two support plates 102c, both of which are fixed to the bottom of the threaded column 101. The support plates 102c can support the excavation plate 102b to prevent the excavation plate 102b from shifting during use.

[0035] Specifically, the limiting member 202 includes a limiting block 202a and a moving bar 202b. The limiting block 202a is arranged on one side of the threaded column 101, and the moving bar 202b is fixed to one side of the limiting block 202a. The moving bar 202b is plugged into one side of the connecting frame 201, and the moving bar 202b and the connecting frame 201 are movably connected.

[0036] A limiting groove is provided on one side of the threaded column 101. After the connecting frame 201 is sleeved on the threaded column 101, the limiting block 202a is engaged with the limiting groove to limit the connecting frame 201 to prevent the connecting frame 201 from falling off. When it is necessary to release the limiting of the connecting frame 201, the moving bar 202b is pulled, and the moving bar 202b drives the limiting block 202a to separate from the limiting groove, thereby releasing the limiting of the connecting frame 201, so that the connecting frame 201 can be removed.

[0037] Specifically, the limiting member 202 further includes a spring 202c, which is sleeved on the outside of the moving bar 202b, with one end of the spring 202c fixed to one side of the limiting block 202a, and the other end fixed to the inner wall of the connecting frame 201.

[0038] When the connecting frame 201 is sleeved on the threaded column 101, the limit block 202a can be squeezed to move it. The movement of the limit block 202a will apply a squeezing force to the spring 202c. After the connecting frame 201 is sleeved on the threaded column 101, the limit block 202a will move to one side of the limit groove, and then the rebound force of the spring 202c can drive the limit block 202a to enter the limit groove, so that the connecting frame 201 can be limited. Installation grooves are provided on the connecting frame 201 and the threaded column 101, which can be engaged with the installation grooves on the two by bolts, and then connected to the device, so as to complete the installation with the device.

[0039] When in use, when the device drives the threaded column 101 to rotate, the two chiseling plates 102b and the drill bit 102a at the bottom can be used for chiseling. The two chiseling plates 102b are in the shape of inner hooks, which is helpful for chiseling rocks and digging soil. The threaded column 101 can be docked with the device by using the connecting frame 201 to facilitate docking. When chiseling, the soil will rise with the spiral part of the threaded column 101. When in use, the drill bit 102a is 3 cm long and will contact the ground first. The solid structure design of the chiseling plate 102b will increase the strength of the structure itself. The coordinated chiseling of the drill bit 102a and the chiseling plate 102b makes the device stable and does not shake, and the connection will not break. The drill bit 102a contacts the ground first, which will give the device a fulcrum when in use, and will not deviate, so that the device can run stably.

[0040] When the connection frame 201 is sleeved on the threaded column 101, the limit block 202a can be squeezed to move it. The movement of the limit block 202a will apply a squeezing force to the spring 202c. After the connection frame 201 is sleeved on the threaded column 101, the limit block 202a will move to one side of the limit groove, and then the limit block 202a can be driven into the limit groove by the rebound force of the spring 202c, so that the connection frame 201 can be limited. When the limit on the connecting frame 201 is to be released, the moving bar 202b is pulled, and the moving bar 202b drives the limit block 202a to separate from the limit groove. At this time, the squeezing force can be applied to the spring 202c, and the movement of the limit block 202a can release the limit on the connecting frame 201, and then the connecting frame 201 can be removed. After the connecting frame 201 is removed, the rebound force of the spring 202c can make the limit block 202a return to its original position for next use.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
