[0021] When in use, the drill rig 1 drives the drill rod 2 and the drill bit 3 to rotate, so as to drill into the rock and form a hole. During the drilling process, the inner support tube 4 is moved forward by tools or hand support until the front end of the front support frame 6 is against the drilling surface. The angles of the front guard plate 8 and the rear guard plate 9 are adjusted to a suitable position by the mechanical angle adjustment mechanism 12, so that the rear reflector 11 is tilted forward and the front reflector 10 is tilted backward. The front reflector 10 can reflect the conditions around the hole, and then the front reflector 10 can be manually observed. On the one hand, workers do not need to directly observe the area around the hole, which reduces the risk of being directly injured by flying debris. On the other hand, the tilted front guard plate 8 and the rear guard plate 9 can block the flying debris, thereby improving the safety protection performance. The mechanical structure has good stability, does not consume additional energy, and is relatively convenient to use.

[0022] An electric lamp 13 is respectively embedded and fixed at the front end of each rear protection plate 9, and the electric lamp 13 is electrically connected to an external circuit control system.

[0023] Furthermore, the electric light 13 that moves synchronously with the rear guard plate 9 can focus light on the conditions around the hole, thereby forming a bright image around the hole on the rear reflector 11 and the front reflector 10 for easy observation.

[0024] The rear part of the outer support cylinder 5 is coaxially threadedly connected with an adjusting cylinder 14, and the front part of the adjusting cylinder 14 is coaxially rotatably connected with a circular front transmission frame 15. A No. 1 hinge seat 16 is fixed to the middle of the rear end of each rear guard plate 9, and the front transmission frame 15 is radially hinged with multiple inner support arms 17 at equal angles around the circumference. The front of each inner support arm 17 is hinged to each No. 1 hinge seat 16, and the rear end of the adjusting cylinder 14 is provided with two mutually parallel clamping platforms 18. 14 is coaxially rotatably connected with an adjustment seat 19, the rear portion of the adjustment seat 19 is in the shape of a hexagonal cylinder coaxial with the adjustment cylinder 14, the adjustment seat 19 is rotatably connected with a rear transmission frame 20 coaxially arranged with the adjustment cylinder 14 and in the shape of a disc, the rear support frame 7 is radially hinged with multiple outer support arms 21 at equal angles around the circumference, and a No. 2 articulated seat 22 is fixed to the end of each front guard plate 8 away from the front support frame 6, and the front portion of each outer support arm 21 is hinged to each No. 2 articulated seat 22.

[0025] The clamping platform 18 is clamped by a tool (such as a wrench) to rotate the adjusting tube 14, thereby moving axially along the outer support tube 5, and the front transmission frame 15 and the inner support arm 17 are driven to move, thereby adjusting the radial angle of the rear guard plate 9 and the rear reflector 11 compared to the outer support tube 5. Similarly, the rear part of the adjusting seat 19 is clamped by a tool to rotate it, thereby moving axially along the adjusting tube 14, and the rear transmission frame 20 and the outer support arm 21 are driven to move, thereby adjusting the radial angle of the front guard plate 8 and the front reflector 10 compared to the outer support tube 5.

[0026] The rear transmission frame 20 penetrates in the front-to-back direction, and a transparent observation panel 23 is closed and fixed at the front-to-back penetration of the rear transmission frame 20 .

[0027] The observation plate 23 can be used to conveniently observe the conditions around the hole and the front reflector 10, and protect the worker's face.

[0028] The front protective plate 8, the outer support arm 21 and the rear transmission frame 20 are collectively sleeved with a detachable filter cover 24, the filter cover 24 is woven from an elastic breathable and water-permeable fabric, the front and rear parts of the filter cover 24 are penetrated in the front-to-back direction, a front elastic band 25 is sewn and fixed along the edge of the penetration of the front part of the filter cover 24, and a rear elastic band 26 is sewn and fixed along the edge of the penetration of the rear part, a plurality of sockets 27 are opened at the front of the filter cover 24, and each of the second hinge seats 22 is respectively fixed with an outward protrusion 28, each of the protrusions The starter 28 is respectively plugged into each socket 27, and the left and right parts of the front elastic band 25 are each fixed with a buckle 29, and the buckle 29 is plugged into the left and right parts of the front support frame 6. The two buckles 29 have a tendency to move away from each other under the elastic pulling of the front elastic band 25. The rear elastic band 26 is penetrated by a plurality of positioning holes 30 along the front and rear directions, and the rear end of the rear transmission frame 20 is fixed with a plurality of positioning pins 31 along the front and rear directions. The rear part of the positioning pins 31 is pointed, and each positioning pin 31 is plugged into each positioning hole 30.

[0029] Furthermore, during the drilling process, since the front end of the front support frame 6 is against the drilling surface, the debris and chip removal liquid (if poured into the hole) can enter the filter cover 24 through the front support frame 6 for filtration, so that the dust and debris can be intercepted and collected, and the liquid can be leaked out, thereby reducing pollution to the outside world, and at the same time, it can prevent the debris from further splashing and causing harm to the human body. When cleaning is required, the positioning hole 30 is disengaged from the positioning pin 31, and then the filter cover 24 is moved forward appropriately to discharge the collected material. When it is moved further forward, the buckle 29 is disengaged from the front support frame 6 and the filter cover 24 can be completely removed.

[0030] The filter cover 24 has openings 32 extending upward at the upper left and right parts respectively, and upper elastic bands 33 are sewn and fixed along the edges of the two openings 32. A cloth cover 34 that can be opened and closed is sewn and fixed to the front of the upper elastic bands 33. The cloth cover 34 is made of elastic, breathable and water-permeable fabric. A plurality of hooks 35 are fixed to the rear of the cloth cover 34, and a plurality of hanging rings 36 are fixed to the rear of the upper elastic bands 33. Each of the hooks 35 is connected to each of the hanging rings 36 under the elastic pulling action of the cloth cover 34, and the cloth cover 34 covers the openings 32 by connecting the hooks 35 with the hanging rings 36.

[0031] Furthermore, when the filter cover 24 is used to collect debris, the opening 32 is directed upwards, and the hook 35 and the hanging ring 36 are connected to realize the cloth cover 34 covering the opening 32, thereby ensuring the interception effect of the flying debris. After opening the cloth cover 34, the conditions around the front reflector 10 and the hole can be conveniently observed through the opening 32. When the debris needs to be discharged, the front support frame 6 is temporarily released from the interference with the drilling surface, and then the outer support tube 5 is rotated so that the opening 32 is directed downwards, and then the cloth cover 34 is opened to conveniently discharge the debris.

[0032] The rotating shaft of the drilling rig 1 is coaxially fastened with a drill rod 2 in a detachable manner by bolts, and the front part of the drill rod 2 is coaxially fastened with a drill bit 3 in a detachable manner by bolts. Three plug blocks 37 are fixed at the front part of the drilling rig 1 at equal angles relative to the circumference of its rotating shaft. The plug blocks 37 are made of permanent magnets, and each of the plug blocks 37 is commonly plugged with a sleeve 38. The sleeve 38 is made of a metal material that can be magnetically attracted to the permanent magnet. The sleeve 38 is magnetically attracted to the plug blocks 37, and the drill rod 2 can rotate relative to the sleeve 38. A spiral compression spring 39 is fixed to the front end of the sleeve 38. The sleeve 38 and the compression spring 39 are gap-connected with the drill rod 2, and the compression spring 39 is in contact with the rear end of the outer support tube 5.

[0033] Furthermore, by utilizing the elastic repulsive force of the compression spring 39, the outer support tube 5 can have a tendency to move forward, thereby facilitating the front support frame 6 to press against the drilling surface or the front support frame 6 to press against the drilling surface through the front elastic band 25. By cooperating with the sleeve 38 and the insert block 37, the sleeve 38 and the compression spring 39 can be easily replaced together.

[0034] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
