[0019] like Figure 1 and Figure 8 As shown, racks 31 are provided on the front and rear surfaces of the U-shaped frame 13, a guide rod 32 is fixedly connected to the inner side of the rack 31, a limit block 33 is slidably connected to the outer side of the guide rod 32, an outer side wall of the limit block 33 is fixedly connected to the outer side wall of the U-shaped frame 13, and a spring 2 34 is fixedly connected between the limit block 33 and the rack 31 and on the outer side of the guide rod 32; A notch 35 is provided on the right side of the workbench 1, and a shaft 36 is rotatably connected to the inside of the notch 35 through a rotating shaft.

The front and rear ends of the shaft 36 are located in front of and behind the workbench 1 and are fixedly connected to a gear 38, which is meshed with the rack 31. After the aerated concrete block moves to the top of the guide plate 37, the rack 31 is used to move the gear 38 to rotate, and the guide plate 37 is controlled to flip and tilt, so as to assist the unloading of the aerated concrete block.

[0020] like Figure 3 and Fig. 9 As shown, the opposite sides of the two screw sleeves 22 are fixedly connected with a vacuum box 39, a fixed pipe 40 is fixedly connected between the vacuum box 39 and the screw sleeve 22, and a corrugated hose 41 is fixedly connected between the fixed pipe 40 and the clamping seat 24; A piston block 42 is slidably connected inside the air extraction box 39, a rotating member 43 is fixedly connected to the right side of the piston block 42, a pull bar 44 is rotatably connected to the rear surface of the rotating member 43 via a rotating shaft, a worm gear 45 is rotatably connected to the right end of the pull bar 44 via a rotating shaft, and the worm gear 45 is rotatably connected to the air extraction box 39 via a rotating shaft; An axle seat 46 is fixedly connected inside the air extraction box 39 and located on the right side of the worm gear 45. A worm 47 is rotatably connected to the left side of the axle seat 46 through a rotating shaft. The worm 47 is meshed with the worm gear 45. A spiral column 48 is fixedly connected to the right end of the worm 47. A toggle rod 49 is movably connected to the outer wall of the spiral column 48. The right end of the toggle rod 49 passes through the right side of the air extraction box 39 and is fixedly connected to an abutment plate 50. A spring 51 is fixedly connected between the abutment plate 50 and the air extraction box 39. When the clamping plate 26 clamps the aerated concrete and moves the aerated concrete to the right to punch holes as the screw sleeve 22 continues to move, that is, when the aerated concrete moves to the guide plate 37, the abutment plate 50 will contact the rack 31, even if the abutment plate 50 is squeezed first, thereby driving the worm 47 to rotate with the spiral column 48, and then under the traction of the pulling bar 44, the control piston block 42 moves to the left, and then the air inside the clamping seat 24 can be extracted, and the control piston seat 25 drives the clamping plate 26 to move, first loosening the clamping of the aerated concrete, and then as the screw sleeve 22 continues to move, the abutment plate 50 will push the rack 31 to move, so that the guide plate 37 flips and tilts, thereby achieving an auxiliary feeding effect.

[0021] Working principle: When in use, first start the electric push rod 23 to control the relative movement of the two clamping seats 24, and then clamp the aerated concrete through the clamping plate 26; Then, the motor 2 15 is started to control the reciprocating screw 16 to rotate, so that the screw sleeve 17 slides along the longitudinal groove 14, thereby controlling the movement of the drilling machine 10 and adjusting the drilling position; Before adjusting the drilling position, the screw rod 6 can be adjusted to rotate to control the movement of the traction rod 8, and then the initial position of the drilling rig 10 can be adjusted to control the up and down reciprocating distance of the drilling rig 10. At this time, the wedge-shaped lifting block 7 will descend and squeeze the piston pressure ring 12, so that the internal gas of the hollow ring 11 is filled into the telescopic air pipe 18, and the L-shaped mounting plate 2 is controlled to drive the drilling rig 10 to rise as a whole. At this time, the distance that the traction rod 8 descends is the same as the distance on the top plate 19, so that the height of the output end of the bottom of the drilling rig 10 descends is the same as the height of the telescopic air pipe 18 extending upward to drive the drilling rig 10 to rise. In this way, when the height of the output end of the bottom of the drilling rig 10 remains unchanged, the disc 4 rotates to control the traction rod 8 to push the drilling rig 10 to descend by different distances, and holes of different depths can be punched on the surface of the aerated concrete; Then, the motor 3 29 is started, and under the drive of the transmission wheel 27 and the transmission belt 28, the two reciprocating screw rods 2 52 are controlled to rotate together, thereby controlling the aerated concrete to move from left to right; Finally, the motor 3 is started to control the disc 4 to rotate one circle, and the started drilling machine 10 is pulled by the traction rod 8 to move up and down repeatedly along the guide rail 53, thereby achieving the effect of aerated concrete drilling.

[0022] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
