[0017] (III) Beneficial effects

[0018] The invention provides a tunnel blasting hole drilling and blasting tube fixing integrated device, which has the following beneficial effects:

[0019] 1. By setting up a first driving component, a drill barrel, a spiral blade, a first drill bit and a conveying component, the first driving component actively rotates the spiral blade of the drill barrel and the first drill bit. Since the first drill bit is evenly distributed along the spiral line of the spiral blade, the first drill bit can continuously perform crushing work during the drilling process of the device. When in use, the device can also continuously convey the first connecting tube and the second connecting tube for fixing the blasting tube outward through the conveying component. During the conveying process, the second drill bit can realize graded drilling work to ensure that the blasting tube can be accurately placed, thereby enhancing the use effect of the device and solving the problem that the existing blasting drilling device cannot convey the blasting tube fixing device to a suitable position after drilling a tunnel and further drill a hole to place the blasting tube. The device can not only realize the graded drilling function, but also can accurately place the blasting tube after drilling to a suitable position.

[0020] 2. By setting up the second drive assembly and the rubber plate, the rubber plate can support the blasting tube without the inner walls of the first connecting tube and the second connecting tube contacting the blasting tube, and can continuously transport the blasting tube outward through the rubber turntable on the second drive assembly. In order to ensure that the blasting tube can be placed at an angle during secondary drilling, the device can tilt the drill tube through the second hydraulic rod so that the second drill bit can drill obliquely downward, thereby ensuring the safety of the device when in use.

[0021] 3. By providing a detachable first connecting tube and a second connecting tube, the blasting tube, the first connecting tube and the second connecting tube can be separated from the device as a whole. The first connecting tube and the second connecting tube can not only be butted against each other through the rubber block of the spherical structure, but can also be separated when the inner walls of the first connecting tube and the second connecting tube are subjected to an outward supporting force. The first connecting tube and the second connecting tube not only have the function of fixing the blasting tube, but also can be used normally without affecting the blasting tube after separation. Compared with the conventional blasting tube fixing structure, the fixing structure can be automatically separated when subjected to impact force, thereby ensuring the blasting effect of the device, and solving the problem that the blasting tube fixing structure of the existing drilling device will affect the blasting effect if it is directly blasted after the fixing is completed.

[0022] 4. The device is provided with an adjustment component spline block and keyway. When the device is in use, the connection block can be pulled, and the connection block will pull the clamping block through the traction steel rope. After the clamping block is stored in the inner groove, the docking angle between the spline block and the keyway can be changed, so that the orientation of the first drill bit on the connection block is no longer tangent to the spiral line of the spiral blade, allowing adjustment according to the hardness and properties of different rock formations. By changing the angle of the first drill bit, the contact mode between the drill bit and the rock can be optimized, thereby improving the crushing effect and crushing efficiency. The angle adjustment of the first drill bit enables the device to adapt to different geological conditions and achieve more efficient rock crushing work. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Embodiment 3:

[0052] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0053] Specifically, when the tunnel blast hole drilling and blasting tube fixing integrated device is used: Figure 1 and Figure 2 As shown, when the device is in use, the second hydraulic rod 32 on the connecting plate 31 is first extended to make the cart 1 tilt forward, and the blasting tube is installed into the first connecting tube 14 and the second connecting tube 15 in the movable groove 10 through the first connecting groove 11, the second connecting groove 12 and the third connecting groove 13.

The rubber plate 18 with an arc-shaped supporting structure allows the blasting tube to be buffered during the drilling process, thereby playing a safety protection function. When the device is drilling, the first motor 403 on the support block 402 drives the gear 404 to rotate, the gear 404 drives the gear ring 405 with a larger diameter to rotate, and the rotating cylinder 406 rotates on the first support cylinder 401, driving the support rod 5, the drill cylinder 6, the spiral blade 7, the connecting block 8 and the first drill bit 9 to rotate. Since the first drill bits 9 arranged equidistantly along the spiral line of the spiral blade 7 are tangent to the spiral line, the device can keep the first drill bit 9 in multi-point contact with the inside of the tunnel when the first hydraulic rod 3 is extended for drilling, thereby improving the drilling efficiency of the device.

[0054] like Figure 3 , Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, after completing the first drilling, the second drilling can be performed. It should be noted that Fig. 9 The back side of the first connecting tube 14 and the second connecting tube 15 is shown in FIG. Fig. 9 The positions of the first connecting tube 14 and the second connecting tube 15 are Fig.11 The positions of the first connecting tube 14 and the second connecting tube 15 are opposite. Figure 3 and Figure 4As shown, the slider 2101 on the conveying assembly 21 can slide inside the slide groove 2103 under the pulling force of the first spring 2104, so that the transverse convex groove 2106 on the rotating wheel 2105 on the second motor 2102 is always in contact with the transverse convex groove 2106 on the first connecting tube 14 and the second connecting tube 15, so that when the rotating wheel 2105 rotates, it drives the first connecting tube 14 and the second connecting tube 15 and the outer side of the blasting tube device inside thereof to move, so as to subsequently convey the blasting tube and the first connecting tube 14 and the second connecting tube 15 outward. After conveying to a suitable position, the drill tube 6 continues to rotate, driving the first connecting tube 14 and the second connecting tube 15 as well as the support shaft 19 and the second drill bit 20 to rotate continuously. During the rotation of the second drill bit 20, it can be in contact with the inside of the tunnel, thereby realizing the secondary drilling function. During the secondary drilling, the second hydraulic rod 32 can be extended, and the cart 1 can be tilted forward as a whole, so that the drilling direction can point to the obliquely downward ground direction, thereby ensuring that the blasting tube can be stably placed in the hole inclined to the ground, ensuring that the blasting tube can be stably placed. When placing the blasting tube, the third motor 2401 drives the connecting shaft 2402 and the rubber turntable 2403 to rotate, and the rubber turntable 2403 can abut against the blasting tube. When the rubber turntable 2403 rotates, the blasting tube is transported outward to the hole of the secondary drilling. The first connecting tube 14 and the second connecting tube 15 on the device can not only play the function of fixing the blasting tube, but also after the inner walls of the first connecting tube 14 and the second connecting tube 15 are pushed outward, the rubber block 23 on the first connecting tube 14 will be separated from the groove 22 in the second connecting tube 15 under the action of tension. After the first connecting tube 14 and the second connecting tube 15 and the blasting tube are transported as a whole into the blasting hole, there is no need to remove the first connecting tube 14 and the second connecting tube 15, which are the fixing structures outside the blasting tube, and the blasting effect of the device can still be guaranteed.

[0055] like Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig.10As shown, the device can change the angle of the connecting block 8 on the spiral blade 7, thereby changing the angle of the first drill bit 9 to adapt to different geological conditions. When adjusting the angle of the first drill bit 9, first pull the connecting block 3006, the connecting block 3006 pulls the traction rope 3004, and the guide ring 3005 on the fixed block 3001 is used to change the direction of the pulling force transmission of the traction rope 3004, so that the traction rope 3004 pulls the block 3003 inside the inner groove 3009, and the block 3003 is affected by When the pulling force is reached, the second spring 3002 will be compressed. After the clamping block 3003 is completely received inside the fixed shaft 28, the fixed shaft 28 will be out of the engagement state with the connecting block 8. At this time, the connecting block 8 can be removed. After changing the angle of the connecting block 8, the spline block 26 and the keyway 25 are realigned and installed. Then, the clamping block 3003 is aligned with the docking grooves 3008 at different positions in the installation groove 3007, so that the fixed shaft 28 and the connecting block 8 are docked again, so that the angle of the first drill bit 9 on the device can be adjusted.
