[0002] During the road construction process, the pavement bricks on the road surface will be drilled, mainly to better install and fix some brackets and fixing frames to facilitate the construction. Generally, the road surface is drilled mainly through the hole-opening equipment;

[0003] For example, the patent website discloses a new type of dust reduction road engineering drilling machine (publication number: CN218117723U). The initial position of the conical barrel of this device is flush with the lower end of the drill bit. In this way, after the drill bit contacts the ground and drills a hole, the drill bit will slowly move down and be inside the drill hole. At this time, the conical barrel will contact and press against the ground. In this way, the dust generated by the drill bit during the drilling process will be blocked by the conical barrel, so that the dust is trapped inside the conical barrel, thereby reducing the suppression of dust and achieving the effect of dust reduction.

[0004] However, there are still some shortcomings in the pavement hole-making equipment used in the above-mentioned patents and the existing market. There are requirements for the hole depth of each pavement brick, but each time the device is used to make a hole, the hole depth is controlled by the user based on experience, which has a large error and is not conducive to novice use. Therefore, this field proposes a pavement brick hole-making equipment with a dust reduction function. Utility Model Content

[0023] See also Figure 1-4The utility model provides a technical solution for a pavement brick drilling device with a dust reduction function: it includes a rebound mechanism 1 and a limiting mechanism 2 installed on its side, the rebound mechanism 1 includes a mounting seat 101, a rectangular cavity 102 is opened inside the mounting seat 101, a slide plate 103 adapted to it is slidingly provided inside the rectangular cavity 102, a first spring 104 is provided on one side of the slide plate 103 inside the rectangular cavity 102, a strip groove 105 communicating with the rectangular cavity 102 is opened on the side of the mounting seat 101, a moving block 106 extending from the strip groove 105 to the outside of the mounting seat 101 is installed on the side of the slide plate 103, a scale is provided on the side of the mounting seat 101 above the strip groove 105, and the starting point of the scale is flush with the moving block 106, the limiting mechanism 2 includes two openings on the mounting seat A rectangular plate 201 is located on the side of the seat 101 and below the strip groove 105. A screw 202 is rotatably installed between the two rectangular plates 201. A threaded seat 203 is provided on the screw 202 and is slidably connected to the side of the mounting seat 101. A limit plate 204 is installed on the side of the threaded seat 203. One end of the screw 202 passes through the rectangular plate 201 and is installed with a knob 205. Before use, determine the required hole depth of the pavement brick. The user rotates the knob 205 to drive the screw 202 to rotate. The rotating screw 202 drives the threaded seat 203 to move. The moving threaded seat 203 drives the limit plate 204 to move until the limit plate 204 points to the scale value on the side of the mounting seat 101, which is the same as the required hole depth of the pavement brick. At this time, the distance between the limit plate 204 and the movable plate 106 is the same as the hole depth.

[0024] The other side of the mounting seat 101 is equipped with a motor 3, a drill bit 4 is installed on the end of the drive shaft of the motor 3, a handle 18 is installed on the side of the motor 3, a ring 5 is sleeved on the drive shaft of the motor 3 and is slidably connected to it, an annular groove 6 is provided on the side of the ring 5, and a mounting ring 7 adapted to it is provided inside the annular groove 6, and a conical cylinder 9 is installed on the port of the mounting ring 7 on the outside of the drill bit 4, and the lower port of the conical cylinder 9 is flush with the lower end of the drill bit 4, a side plate 16 is installed on the side of the ring 5, and an end is installed on the side of the side plate 16 The connecting rod 17 extends into the rectangular cavity 102 and is fixedly connected to the slide plate 103. When in use, the user holds the device through the handle 18, so that the drill bit 4 is facing and in contact with the opening position of the pavement brick and is in a vertical position. The conical cylinder 9 covers the pavement brick. Since the lower end of the conical cylinder 9 is provided with a rubber ring, the lower end of the conical cylinder 9 fits the pavement brick more closely. The motor 3 is energized to drive the drill bit 4 to rotate. The rotating drill bit 4 descends to drill holes in the pavement brick. The waste dust generated by drilling will be blocked by the conical cylinder 9, which has a dust reduction effect.

[0025] Two sockets 8 are correspondingly provided on the side of the mounting ring 7 inside the annular groove 6. A fixing seat 10 is provided on one side of each socket 8 on the side of the circular ring 5. A cavity 11 is provided inside each fixing seat 10. A slider 12 adapted to it is slidably provided in each cavity 11. A pull rod 14 is installed on the side of each slider 12, the end of which extends to the outside of the fixing seat 10. A second spring 15 is sleeved on the pull rod 14 in each cavity 11. A plug-in 13 is installed in each socket 8, the end of which extends to the nearest cavity 11 and is fixedly connected to the slider 12. When the conical cylinder 9 needs to be removed, it is only necessary to pull the two pull rods 14 outward to drive the two sliders 12 away from each other. Each moving slider 12 compresses the second spring 15 while driving the plug-in 13 to move out of the inserted socket 8, thereby releasing the fixation of the mounting ring 7, and the mounting ring 7 connected to the conical cylinder 9 can be removed from the circular ring 5.

[0026] The working principle of the present invention is as follows: before use, the required hole depth of the pavement brick is determined first. The user rotates the knob 205 to drive the screw 202 to rotate. The rotating screw 202 drives the threaded seat 203 to move. The moving threaded seat 203 drives the limiting plate 204 to move until the limiting plate 204 points to the scale value on the side of the mounting seat 101 that is the same as the required hole depth of the pavement brick. At this time, the distance between the limiting plate 204 and the movable plate 106 is the same as the hole depth.

[0027] The user holds the device by means of the handle 18, so that the drill bit 4 is facing and in contact with the hole position of the pavement brick and is in a vertical position, and the conical cylinder 9 covers the pavement brick. Since the lower end of the conical cylinder 9 is provided with a rubber ring, the lower end of the conical cylinder 9 is more closely fitted to the pavement brick. The motor 3 is energized to drive the drill bit 4 to rotate. The rotating drill bit 4 descends to drill the pavement brick. The waste dust generated by the drilling will be blocked by the conical cylinder 9, which plays a dust reduction role.

[0028] The descending drill bit 4 will be lowered along with the motor 3. Since the conical cylinder 9 is covered on the pavement bricks and thus cannot descend, the descending motor 3 will drive the mounting base 101 to descend. Since the slide plate 103 is stationary, the inner wall of the movable mounting base 101 cooperates with the slide plate 103 to squeeze the first spring 104, and at the same time, the moving block 106 moves in the strip groove 105. When the moving block 106 contacts the limit plate 204, it means that the drill bit 4 has descended a distance to reach the hole opening distance. Then the motor 3 is turned off, and the moving device removes the drill bit 4 from the hole. After that, the compressed first spring 104 rebounds and drives the conical cylinder 9 to restore its position.

[0029] When the conical tube 9 needs to be removed, it is only necessary to pull the two pull rods 14 outward to drive the two sliders 12 away from each other. Each moving slider 12 compresses the second spring 15 while driving the plug-in 13 to move out of the inserted socket 8, thereby releasing the fixation of the mounting ring 7. The mounting ring 7 connected to the conical tube 9 can be removed from the circular ring 5. During installation, it is only necessary to insert the mounting ring 7 on the conical tube 9 into the annular groove 6 and reinsert the two plug-ins 13 into the two sockets 8. This makes the disassembly operation of the conical tube 9 simple, and it is convenient to remove the conical tube 9 and clean the dust on the surface of the conical tube 9 and the drill bit 4. At the same time, the conical tube 9 can be replaced after being broken by flying fragments when drilling a hole.
