In this embodiment, as shown in fig. 2, four mounting holes 9 are formed in the circumferential corner of the fixing plate 1, correspondingly, four mounting pieces 10 are provided, each mounting piece 10 adopts a fixing pin, the fixing plate 1 is attached to a working surface to be drilled, and the fixing pins are inserted into the corresponding mounting holes 9 and rotated, so that the fixing connection between the fixing plate 1 and the working surface is completed. According to practical application, the number of the installation holes 9 and the specific installation positions on the fixing plate 1 can be adjusted, and the installation part 10 can be other structural members capable of fixing the fixing plate 1.

The use of the drilling apparatus is further described below:

when the drill rod cleaning device is used, the fixed plate 1 is fixed on a working surface to be drilled, the positions of the two moving frames 62 on the fixed frame 61 are moved, the cleaning brushes 63 on the two moving frames 62 are not contacted with the drill rod 5, the third driving piece 41 is started, the first transmission gear 42 and the second transmission gear 43 which are directly or indirectly connected with the output shafts of the third driving piece 41 rotate, the drill rod 5 connected with the second transmission gear 43 is further driven to rotate, the output shaft of the second driving piece 22 is initially in an extension state, the second driving piece 22 is started, the output shaft thereof begins to contract, the lifting column 23 and the placing plate 3 which are directly or indirectly connected with the second driving piece are driven to move towards the fixed plate 1, and the placing plate 3 falls into the limiting frame 72 in the moving process and is limited by the limiting frame 72, the placing plate 3 continues to move without shaking in the horizontal direction, pressure is applied to the limiting frame 72, so that the telescopic piece 71 connected with the limiting frame 72 contracts, the placing plate 3 moves to drive the drill rod 5 connected with the placing plate to move towards the drill hole 11, and the rotary drill bit 51 and the drill rod 5 penetrate through the drill hole 11 to perform drilling operation on a working surface. After the drill rod 5 is drilled to a set depth, the second driving element 22 is turned off, the moving frames 62 at the two sides of the drill rod 5 move towards the drill rod 5 along the fixed frame 61, and the cleaning brush 63 stops moving when contacting the drill rod 5, at this time, the first driving element 64 is started, the output shaft of the first driving element 64 stretches and retracts to drive the connecting plate 65 and the cleaning brush 63 which are directly or indirectly connected with the first driving element to reciprocate along the extending direction of the moving frames 62, and at the same time, the second driving element 22 is restarted to enable the output shaft of the second driving element 22 to extend, so as to drive the lifting column 23, the placing plate 3 and the drill rod 5 which are directly or indirectly connected with the second driving element to move in the direction away from the fixed plate 1, namely, the drill rod 5 is pulled out of the drill hole, and the placing plate 3 moves in the direction away from the fixed plate 1, the expansion member 71 gradually resumes the elongation. Along with the drill rod 5 is slowly taken out, the cleaning brush 63 cleans rock mud adhered to the drill rod 5 in the circumferential direction in the drilling process under the combined action of reciprocating movement and rotation of the drill rod 5, the cleaning brush 63 cleans the drill rod 5 by means of friction between the cleaning brush and the drill rod 5, when the drill rod 5 is completely taken out, the cleaning brush 63 finishes cleaning the drill rod 5, and at the moment, the first driving piece 64, the second driving piece 22 and the third driving piece 41 are stopped, and the drilling work is finished.

By adopting the drilling device, the cleaning brush 63 in the cleaning assembly 6 is not contacted with the drill rod 5 in the drilling process, the cleaning brush 63 is adjusted to be contacted with the rotating drill rod 5 after the drilling is carried out to the set depth, and the rock mud on the surface of the drill rod 5 is cleaned by utilizing the friction between the cleaning brush 63 and the drill rod 5 in the process of taking out the drill rod 5, so that the condition that the rock mud is adhered to the surface of the drill rod after the drill rod is used is prevented, and the drilling device is convenient to reuse.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
