[0021] In this embodiment, when in use, the motor 1 2 is started to rotate forward or reversely, thereby driving the screw 3 to rotate so that the mounting plate 4 moves up and down. When it moves to the appropriate position, the hydraulic cylinder 5 is started to push the motor 2 6 and the drill rod 8 to move. At the same time, the motor 2 6 is started to drive the drill rod 8 to rotate, thereby contacting the rock surface to work. Example 2

[0022] like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, spring blocks 41 are fixedly connected to the right sides of the front and rear sides of the mounting plate 4, and springs 42 are fixedly connected to the right sides of the front and rear spring blocks 41. A through hole 43 communicating with each other up and down is opened on the right side of the upper surface of the mounting plate 4. A slide groove 44 is opened on the right sides of the front and rear sides of the mounting plate 4, and the inner wall of the slide groove 44 is connected to the inside and outside on the right side. The protective component 9 includes a protective cover shell 91, a square connecting sleeve 901, and a water tank 902. The middle left side of the inner wall of the protective cover shell 91 is movably connected to the outer surface of the drill rod 8, and the lower surface of the protective cover shell 91 overlaps the upper surface of the mounting plate 4. The front and rear left sides of the protective cover shell 91 are fixedly connected to vertical blocks 92, and the left sides of the front and rear vertical blocks 92 are respectively An L-shaped plate 95 is fixedly connected to the right end of the spring 42, and the front right side of the mounting plate 4 is fixedly connected. A micro motor 93 is fixedly connected to the left side in the horizontal direction of the L-shaped plate 95.

Cams 94 are passed through and fixedly connected to the front and rear sides of the outer surface of the output shaft of the micro motor 93. Blocks 921 are fixedly connected to the right sides of the opposite surfaces of the front and rear vertical blocks 92.

At the same time, the spring 42 is in a contracted state, and the drill rod 8 is moved out of the inside of the rock by starting the hydraulic cylinder 5. The drill bit exposed from the protective cover shell 91 before use facilitates workers to observe whether there is a deviation in the contact part with the rock, thereby facilitating the position adjustment of the drill rod 8. When the drill bit in the drill rod 8 is accurately positioned, it is convenient to close the protective cover shell 91 to achieve the protective effect. Example 3

[0025] In this embodiment, when the cam 94 pushes the vertical block 92, the circular rubber block 923 enters the interior of the positioning groove 922, and the circular rubber block 923 is deformed and contracted, so that the outer surface of the contracted circular rubber block 923 is tightly fitted with the inner wall of the positioning groove 922, thereby achieving the effect of position restriction when the cam 94 pushes the vertical block 92. The setting of the pattern 9232 facilitates the increase of friction when the positioning groove 922 contacts, thereby improving the position stability of the cam 94. Example 4

The setting of the filter plate 906 protects the water pump 907, prevents the dust particles in the water on the right side of the water tank 902 from invading the water pump 907, and improves the service life of the water pump 907. The setting of the U-shaped positioning plate 903 and the strip groove 904 facilitates the installation and disassembly operations of the water tank 902 and the square connecting sleeve 901, and facilitates the replacement of the water in the water tank 902.

Otherwise, the replaced drill rod 8 is inserted into the circular opening inside the sleeve 71, and the outer surface of the L-shaped plug plate 701 is inserted into the inside of the first slot 703, and then the positioning sleeve 73 is moved and snapped into the inside of the L-shaped plug plate 701 for positioning, and the plug block 702 is inserted into the inside of the second slot 704, and the threaded sleeve 72 is rotated clockwise to connect and fix it with the threads on the surface of the plug block 702 and the sleeve 71, so as to facilitate installation.

[0030] The following is a detailed description of the working principle of the hydraulic anchor drilling rig protective device.

[0031] like Figure 1-7As shown, by starting the micro motor 93, the front and rear cams 94 are driven to rotate downward and separate from the vertical block 92. Due to the elastic action of the contracted spring 42, the vertical block 92 and the protective cover shell 91 are pushed to move. When they are moved to the appropriate position, the protective cover shell 91 is tightly fitted with the surface of the rock, thereby achieving a protective effect. At the same time, the water in the water tank 902 is pumped by starting the water pump 907, so that the water is transported to the inside of the square tube 908, and the water is sprayed out through the nozzle 909 to reduce the dust inside the protective cover shell 91.
