The drilling assembly 30 is rotatable about a second directional axis. For ease of understanding, the drilling assembly 30 is rotatable in a vertical plane, as shown in fig. 2.
A first end of boom 40 is pivotally connected to boom mount 20 and a second end of boom 40 is pivotally connected to drilling assembly 30. Specifically, as shown in fig. 1, the cantilever mount 20 is provided with a first pair of connection lugs 201 and a second pair of connection lugs 202, the first pair of connection lugs 201 and the second pair of connection lugs 202 are opposite and spaced apart from each other, two connection lugs in each of the first pair of connection lugs 201 and the second pair of connection lugs 202 are opposite and spaced apart from each other, a first end of the cantilever 40 (a rear end of the cantilever 40 in fig. 1) is connected between the first pair of connection lugs 201, and the cantilever 40 is swingable in a vertical plane to adjust the lifting and lowering of the cantilever 40.

Further, a cylinder body 501 of the first telescopic cylinder is pivotally connected with the cantilever mounting base 20, and a piston rod 502 of the first telescopic cylinder is pivotally connected with the cantilever 40. As shown in fig. 1 and 4, the cylinder body 501 of the first telescopic cylinder is connected between the second pair of connecting lugs 202, so that the rotating arm mounting base can be used as a fulcrum, the first telescopic cylinder 50 can be used as a telescopic support, when the piston rod 502 of the first telescopic cylinder extends, the cantilever 40 swings upwards around the cantilever mounting base 20, and the height of the drilling assembly 30 rises. For ease of understanding, reference may be made to the dynamic diagram of cantilever 40 shown in FIG. 3.
As shown in fig. 3, the cylinder 601 of the second jack cylinder is pivotally connected to the boom 40 and the piston rod 602 of the second jack cylinder is pivotally connected to the drilling assembly 30. Thus, the boom 40 may act as a fulcrum and the second ram 60 may act as a telescopic adjustment rod, and as the piston rod 602 of the second ram extends, the drilling assembly 30 rotates upward to change its elevation angle. The inventor finds that, in the rock drilling, anchoring and protecting all-in-one machine 1 in the related art, in order to ensure that the drilling assembly 30 can always ensure that the drilling direction is vertical to the wall surface, a rotary motor is usually arranged to control the elevation angle of the drilling assembly 30, but the rotary motor is used as an independent power element, a special control device needs to be equipped, the complexity of operation is increased, the cost of the rotary motor is high, the assembly is complex, and the overall cost performance and the structural layout of the rock drilling, anchoring and protecting all-in-one machine 1 are affected.

In some embodiments, as shown in fig. 3 and 4, the drilling assembly 30 includes a bit base 301, a bit support 302, and a drill bit (not shown) mounted on the bit support 302, the bit support 302 being rotatably mounted on the bit base 301 about the first directional axis, the second end of the boom 40 (the forward end of the boom 40 in fig. 3) being pivotally connected to the bit base 301, and the piston rod 602 of the second telescopic cylinder being pivotally connected to the bit base 301.
As shown in fig. 3 and 4, the front end of the piston rod 602 of the second telescopic cylinder is connected to the drill base 301, and when the piston rod 602 of the second telescopic cylinder extends, the front end of the piston rod 602 of the second telescopic cylinder can push the drill base 301 to rotate upward, and the drill support 302 and the drill bit disposed on the drill support 302 both rotate upward along with the drill base 301.
As shown in fig. 3, when the drilling assembly 30 is operated at different height positions of the sidewall, the elevation angle of the drill bit can be adjusted by using the piston rod 602 of the second telescopic cylinder to make the drilling direction of the drill bit perpendicular to the wall surface. And as shown in fig. 2 and 4, the drill bit may also be made perpendicular to the top or bottom wall by changing the elevation angle of the drill bit when the drilling assembly 30 is operating on the top or bottom wall.
In addition, when the drilling assembly 30 is operating on a plurality of sidewalls, the drill base 301 may drive the drill base 302 and the drill bit disposed on the drill base 302 to rotate in a horizontal direction, so that the drill bit may be drilled or anchored on the sidewalls in different directions. Preferably, the bit base 301 may be a rotary motor.

Therefore, the second telescopic cylinder 60 can control the rotation of the connecting plate 703 by controlling the extension and retraction of the piston rod 602 of the second telescopic cylinder, so as to adjust the elevation angle of the drill bit base 301, and further keep the drilling direction of the drill bit perpendicular to the side wall, the top wall or the bottom wall all the time.
In addition, as shown in fig. 5, the first link 701, the second link 702, the connecting plate 703 and the cantilever 40 may form a substantially four-bar structure, so as to prevent the connecting assembly 70 from being locked.
Further, as shown in fig. 5, the first link 701 includes a first segment 7011 and a second segment 7012, the first segment 7011 and the second segment 7012 having a predetermined included angle therebetween.

Therefore, when the piston rod 602 of the second telescopic cylinder extends and retracts by a certain amount, the first link 701 can push the second link 702 to have a larger movable stroke, so that the adjustable range of the elevation angle of the drilling assembly 30 is increased.
In addition, the lower end of the second segment 7012 is connected to the second link 702, and the inclined direction of the second segment 7012 can be changed by forming an included angle between the first segment 7011 and the second segment 7012, so that the second segment 7012 is connected to the second link 702 smoothly and is not easily jammed.

It is understood that the second link 702 can drive the connecting ear 7034 to rotate, and the connecting ear 7034 can drive the triangular plate 7033 to rotate around the pivot point between the triangular plate 7033 and the suspension arm 40. Further, as shown in fig. 5, the connection plate 703 further includes a mounting plate 7032, the side of the connection bracket 7031 facing the mounting plate 7032 includes a first surface and a second surface, the first surface and the second surface are vertically connected, the mounting plate 7032 is connected to both the first surface and the second surface, and the drill support 302 is connected to the mounting plate 7032.
