[0019] Reference Figures 1-5 The multi-drilling device for blasting construction includes a support frame 1 and a support plate 2. A plurality of movable plates 3 are movably connected in the middle of the support plate 2. The drilling efficiency is accelerated by the plurality of movable plates 3. The left and right ends of the top of the movable plate 3 are fixed with limit assemblies 4. The limit assemblies 4 can limit the movable plate 3. The top center of the movable plate 3 is threadedly connected to a motor 5. The rotating end of the motor 5 is directly connected to a drill rod 6, which is driven by the motor 5 to drill holes in the ground.

[0020] The limiting assembly 4 includes a fixed plate 7 welded to the motor 5, and slots 8 are provided in a linear array at both ends of the top of the support plate 2. Several plug rods 9 movably connected to the fixed plate 7 are passed through the surface of the fixed plate 7, and the plug rods 9 are inserted into the interior of the slots 8. The outer surface of the plug rod 9 is sleeved with a spring 10, and a pull rod 11 is welded to the other end of the spring 10. The plug rod 9 is driven to move by pulling the pull rod 11, and the movement of the plug rod 9 compresses the spring 10. When the pull rod 11 is released, the plug rod 9 is driven to move by the elasticity of the spring 10 itself, so that the plug rod 9 is inserted into the interior of the slot 8, thereby limiting and fixing the movable plate 3.

[0021] Limiting grooves 12 are provided at both ends of the inner portion of the support plate 2, and limiting rods 13 inserted into the limiting grooves 12 are integrally formed at the left and right ends of the movable plate 3. The movable plate 3 can be limited in movement by the limiting rods 13 and the limiting grooves 12 to prevent it from moving up and down during operation.

[0022] Roller grooves 14 are provided at both ends of the inner portion of the support plate 2, and rollers 15 inserted into the roller grooves 14 are movably connected at both ends of the bottom of the movable plate 3. The roller grooves 14 and the rollers 15 make it possible to move the movable plate 3 smoothly and labor-savingly.

[0023] The left and right ends of the top of the support frame 1 are both threadedly connected with electric telescopic rods 16, and the telescopic ends of the electric telescopic rods 16 are threadedly connected to the top of the support plate 2. The electric telescopic rods 16 drive the support plate 2 to move up and down, making it convenient to drill holes in the ground.

[0024] Support rods 17 are welded to the four corners of the bottom of the support frame 1, and the bottom of the support rods 17 is threadedly connected to a universal wheel 18, which facilitates the movement of the pushing device.

[0025] When using this device, first use a measuring tool to determine the hole position of each blasthole, then push the support frame 1 to the place where a hole needs to be drilled, then pull the pull rod 11 to drive the insertion rod 9 to move, and at the same time, the movement of the insertion rod 9 compresses the spring 10, so that the insertion rod 9 is away from the slot 8, and then the drill rod 6 is aligned with the hole position by moving the movable plate 3. At this time, when the pull rod 11 is released, the spring 10 itself elastically drives the insertion rod 9 to move, so that the insertion rod 9 is inserted into the inside of the slot 8, thereby limiting and fixing the movable plate 3, and then repeating the above steps to make multiple drill rods 6 aligned with the hole position, and then start the motor 5 to drive the drill rod 6 to rotate, and at the same time start the electric telescopic rod 16 to drive the drill rod 6 to drill into the ground.
