[0002] Pneumatic rock bolt drilling rigs need to be equipped with a retaining ring. The existing retaining ring is a simple stainless steel ring. There are two brackets under the stainless steel ring. Two mounting holes are opened on each bracket. The body base of the drilling rig Corresponding mounting holes on both sides are provided with threaded holes, and then the bracket is connected to the base of the drilling rig with screws. Such a retainer cannot adjust the direction, and the protective effect is not ideal.

Embodiment Construction
[0018] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0019] Such as Figure 1-3 The body of the multifunctional pneumatic rock bolt rig shown includes a base 1 and a retainer 2. A mounting bracket is respectively provided under both sides of the retainer 2. The two mounting brackets are symmetrical to each other and are respectively located in the middle of the lower sides of the retainer 2. . The mounting bracket includes a slanting frame 4 and a horizontal plate 5 , the slanting frame 4 and the horizontal plate 5 are integrated, and the top of the slanting frame 4 is welded to the retaining ring 2 . The two ends of horizontal plate 5 have a large groove 6 respectively, and the same side of two large grooves ...

The invention discloses a multifunctional pneumatic anchor rod drilling machine body which comprises a base and a retainer and further comprises four screws. The lower portions of the two sides of theretainer are each provided with a mounting support, and the mounting supports each comprise an oblique frame and a transverse plate. The two ends of the transverse plates are each provided with a large groove, the same sides of the two large grooves are each provided with a small groove, and the large grooves and the small grooves communicate. A boss is outwards arranged on the periphery of the base by one circle, and four lower mounting holes are evenly formed in the boss. The widths of the large grooves are at least equal to the diameters of the lower mounting holes, and the widths of the small grooves are smaller than the diameters of the lower mounting holes. The transverse plates are located above the base, and the four small grooves in the two transverse plates correspond to four ofthe lower mounting holes in the base. The diameters of the screws are equal to those of the lower mounting holes, and a plurality of contraction sections are arranged on each screw rod. The diametersof the contraction sections are equal to the widths of the small grooves, and the lengths of the contraction sections are equal to the thicknesses of the transverse plates. According to the multifunctional pneumatic anchor rod drilling machine body, the direction of the retainer can be adjusted according to demands, and the protective effect is good.
Description
technical field [0001] The invention relates to a pneumatic rod drilling machine, in particular to a multifunctional pneumatic rod drilling machine body. Background technique [0002] Pneumatic rock bolt drills all need to be provided with a retaining ring. The existing retaining ring is a simple stainless steel ring. There are two brackets under the stainless steel ring. Two mounting holes are opened on each bracket. The body base of the drilling rig Corresponding mounting holes on both sides are provided with threaded holes, and then the bracket is connected to the base of the drilling rig with screws. Such a retainer cannot adjust the direction, and the protective effect is not ideal. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the present invention provides a multifunctional pneumatic rock bolter body that can adjust the direction of the retainer according to requirements and has a good protective effect. A mounting bracke...
