[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.
[0027] In order to solve the problem that the anchor drill bit is prone to shaking during use of hydraulic anchor drilling rigs, which may damage the drilling rig parts and shorten the service life of the drilling rig, please refer to Figures 1 to 5 The structure of the device body is a support seat 1 and an anchor drill bit 3 for construction drilling. The drilling work is achieved by rotating the anchor drill bit 3. An inverted U-shaped support frame 2 is welded on the side of the support seat 1. The support seat 1 provides support and fixing for the support frame 2. A rotating rod 4 is welded on the top surface of the anchor drill bit 3. There are two limit bearings 5 on the side of the rotating rod 4 with interference fit. The outer rings of the two limit bearings 5 are embedded and fixedly connected with an internal hollow fixed plate 6, and the two limit bearings 5 are respectively located on the inner top wall and inner bottom wall of the fixed plate 6 to realize the relative rotation of the fixed plate 6 and the rotating rod 4. Two connecting plates 8 are welded on the side of the fixed plate 6. A movable frame 9 is welded on the end face of the connecting plate 8. The inner wall of the movable frame 9 is slidably connected to the support frame 2.
[0028] The two pillars of the support frame 2 are respectively slidably connected to the inner side walls of the two mobile frames 9, thereby fixing the longitudinal movement paths of the two mobile frames 9. Under the connection provided by the connecting plate 8, the rotation stability of the rotating rod 4 is improved, thereby preventing the anchor drill bit 3 from shaking during drilling work, causing damage to the parts of the hydraulic anchor drill rig, thereby extending the service life of the hydraulic anchor drill rig. The inner wall of the fixed plate 6 is rotatably connected with a rotating plate 7. The top surface of the rotating plate 7 is embedded and fixedly connected to the rotating rod 4, and the bottom surface of the rotating rod 4 passes through the rotating plate 7, so that the rotating plate 7 is located on the inner side wall of the fixed plate 6 for rotation, reducing the lateral force on the two limit bearings 5, thereby preventing damage to the limit bearings 5. The top surface of the rotating rod 4 is detachably connected to the output shaft of the rotating motor 10 by bolts, and the fixed end of the rotating motor 10 is installed with a mounting plate 11. The bottom surface of the mounting plate 11 is detachably connected to the fixed end of the rotating motor 10 by bolts, so that the rotating motor 10 provides power, and the anchor drill bit 3 is rotated during the transmission process to achieve drilling work.
[0029] The top surface of the mounting plate 11 is detachably connected to the movable end of the hydraulic rod 12 by bolts, and the fixed end of the hydraulic rod 12 is embedded in the support frame 2. A through groove is provided on the inner top wall of the support frame 2, and the inner wall of the through groove of the support frame 2 is detachably connected to the hydraulic rod 12 by bolts. At the same time, the longitudinal position of the anchor drill bit 3 is controlled during the transmission process through the provided hydraulic rod 12, and the longitudinal position requirement of the anchor drill bit 3 during drilling work is adapted.
[0030] The dust suppression component 14 includes an inverted U-shaped fixing frame 15 and an internal hollow connecting rod 17. The two side walls of the fixing frame 15 are embedded with rotating blocks 16 for rotation. The fixing frame 15 is set to fix the rotation position of the two rotating blocks 16. The adjacent sides of the two rotating blocks 16 are welded to the connecting rod 17 to fix the rotation position of the connecting rod 17. The side of the connecting rod 17 is connected to a number of nozzles 18 for spraying clean water. The right rotating block 16 is embedded and fixedly connected with a sealed bearing 20. The inner ring of the sealed bearing 20 is interference-fitted with a conduit 21. The provided sealed bearing 20 provides a sealing effect and facilitates the relative rotation of the conduit 21 and the right rotating block 16, thereby improving the hydraulic anchor. The functional structure of the drilling rig is stable. Water is introduced into the conduit 21 through an external water pump. The end face of the conduit 21 extends into the inner cavity of the connecting rod 17, and then the water flows into the inner cavity of the connecting rod 17 through the conduit 21 and is sprayed out through a number of nozzles 18 to provide dust reduction. The rotating block 16 on the left is detachably connected to the output shaft of the drive motor 19 by bolts. The fixed end of the drive motor 19 is detachably connected to the fixed frame 15 by bolts. The set drive motor 19 provides power, which makes it easy to control the angle of the water spraying from the several nozzles 18 during the transmission process, thereby improving the dust reduction range of the dust generated by the drilling work of the hydraulic anchor drilling rig and improving the dust reduction effect. The top surface of the fixed frame 15 is welded to the support seat 1.
[0031] The rotating motor 10, the hydraulic rod 12, and the drive motor 19 are all prior art. Their working principles, sizes, and models are irrelevant to the functions of this application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
[0032] How it works
[0033] When the user is using the hydraulic anchor drill rig, the output shaft of the rotating motor 10 drives the anchor drill bit 3 to rotate during the rotation process to realize the drilling work. The set rotating rod 4 provides a connecting function, and at the same time, the rotating plate 7 fixedly connected to the rotating rod 4 is moved in the inner cavity of the fixed plate 6. The set connecting plate 8 provides a connecting function, and at the same time, the moving frame 9 moves along the pillar of the support frame 2. During the transmission process, the anchor drill bit 3 is prevented from shaking during the rotation drilling process, causing damage to the parts of the hydraulic anchor drill rig, thereby extending the service life of the hydraulic anchor drill rig. The two limit bearings 5 set realize the relative rotation of the rotating rod 4 and the fixed plate 6, thereby improving the structural stability of the drilling rig parts.
[0034] Water is introduced into the conduit 21 through an external water pump, so that the water flows into the inner cavity of the connecting rod 17 and is then sprayed out through a number of nozzles 18, thereby achieving dust reduction treatment for the dust generated by the drilling work of the hydraulic anchor drilling rig, preventing the dust from escaping and polluting the air environment. The fixed frame 15 is fixed to the rotation position of the two rotating blocks 16, thereby improving the rotation stability of the connecting rod 17. The drive motor 19 is provided to provide power, so that the angles of the several nozzles 18 are controlled during the rotation of the output shaft of the drive motor 19, so as to increase the range of water sprayed by the nozzle 18 and improve the dust reduction effect.
