Specific implementation

[0030] The technical scheme in the utility model embodiment is clearly and completely described below in combination with the drawings in the utility model embodiment. In the following description, a large number of specific details are set forth to enable a full understanding of the utility model, but the utility model can also be implemented in other manners different from those described herein, and a person skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0031] The structure of the down-the-hole drill is as shown in Figures 1-3 Fig. 1, comprising a frame body 100, a sliding seat 200, a motor 300, a drill rod 400, and a support rod 500. The sliding seat 200 is slidingly arranged on the frame body 100, the motor 300 is fixedly arranged on the sliding seat 200, the output shaft of the motor 300 is fixedly connected with the drill rod 400 to drive the drill rod 400 to rotate, the bottom of the frame body 100 is fixedly provided with a limiting seat 600, the bottom of the drill rod 400 passes through the limiting seat 600 and performs downward drilling, and the support rod 500 is rotatably connected with the top of the frame body 100.

[0032] As shown in Figures 1-4 The utility model discloses a dust collecting device of down-the-hole drill, which is installed on the frame body 100 of the down-the-hole drill and mainly comprises a dust absorption head 1, a connecting pipe 3, a dust collector 2 and a collection box 4.

[0033] The dust suction head 1 is annular and is installed at the bottom of the frame 100 of the down-the-hole drill rig, and is sleeved on the outside of the drill rod 400 of the down-the-hole drill rig. The dust suction head 1 includes a receiving part 101 and a dust suction part 102. The receiving part 101 is sleeved on the outside of the drill rod 400 of the down-the-hole drill rig. The receiving part 101 mainly serves to connect and initially receive dust, collecting the dust generated around the drill rod 400 so that it can be transported to the collection box 4 through the connecting pipe 3. A connecting plate 5 is fixedly installed at one end of the receiving part 101, and the connecting plate 5 is connected to the collection box 4 through the connecting pipe 3. The first bolt 6 is fixedly installed at the bottom of the frame 100 of the down-the-hole drill. Specifically, multiple first mounting holes are opened around the connecting plate 5, and multiple second mounting holes are opened on the limiting seat 600 of the down-the-hole drill. The first bolt 6 passes through the first mounting holes and the second mounting holes in sequence and is locked with a nut. This connection method makes it easier to install and remove the dust collection head 1, facilitates the maintenance and replacement of the dust collection head 1 components, and ensures the stability of the dust collection head 1 during operation, ensuring that it can accurately collect dust. The side wall of the receiving part 101 is connected to the connecting pipe 3. The dust collection part 102 is frustum-shaped, which allows for a wider dust collection range. It is fitted onto the outside of the drill rod 400 of the down-the-hole drill. The small-diameter end of the dust collection part 102 is fixedly connected to the other end of the receiving part 101, and the interior of the dust collection part 102 is connected to the interior of the receiving part 101. The large-diameter end of the dust collection part 102 has multiple dust collection holes 103 that communicate with the interior of the dust collection part 102. The dust collection holes 103 are channels for dust to enter the dust collection part 102. The multiple dust collection holes 103 ensure a larger dust collection area and improve dust collection efficiency. A filter screen 7 is covered on the dust collection holes 103. The filter screen 7 can prevent larger particles of impurities from entering the dust collection head 1 and subsequent components such as the vacuum cleaner 2 and connecting pipe 3, avoiding damage to the equipment caused by impurities. It also helps to ensure the purity of the collected dust, making the collected dust easier to process later.

[0034] The inlet of the vacuum cleaner 2 is connected to the other end of the connecting pipe 3. The vacuum cleaner 2 is fixedly mounted on the collection box 4, and the outlet of the vacuum cleaner 2 is connected to the collection box 4. The vacuum cleaner 2 in this embodiment is prior art and will not be described in detail here.

[0035] The collection box 4 has a dust discharge port on its side wall, and a door is provided on the dust discharge port to facilitate the centralized cleaning of dust inside the collection box 4. The collection box 4 is slidably and rotatably connected to the bottom of the frame 100 of the down-the-hole drill. Specifically, a T-shaped slide rail 12 is fixedly installed on the bottom side of the frame 100 of the down-the-hole drill, and a sliding seat 8 is slidably installed on the T-shaped slide rail 12. A connecting ear 9 is provided on the top side wall of the collection box 4. The connecting ear 9 is hinged to the sliding seat 8, and the pivot between the connecting ear 9 and the sliding seat 8 is a second bolt 10, on which a locking nut is fitted. This structure allows the collection box 4 to rotate and adjust its position relative to the frame 100 of the down-the-hole drill, ensuring that the bottom of the collection box 4 is always placed on the ground and locked with bolts and lock nuts. This provides further support for the frame 100 of the down-the-hole drill and makes it easy to rotate the collection box 4 to a suitable position when cleaning it. The lock nuts can then fix the collection box 4 in place after the position is adjusted, ensuring its stability during operation.

[0036] The connecting pipe 3 includes a first pipe body 31, a second pipe body 32, and a telescopic pipe 33. One end of the first pipe body 31 is connected to the receiving part 101, and one end of the second pipe body 32 is perpendicularly connected to the other end of the first pipe body 31. This perpendicular connection method can flexibly change the direction of dust conveying according to the structure and spatial layout of the down-the-hole drill frame 100, so as to better connect it to the vacuum cleaner 2. The second pipe body 32 is fixedly installed on the down-the-hole drill frame 100 by a fixing member 11. The fixing member 11 can ensure that the second pipe body 32 remains stable during the operation of the down-the-hole drill, and avoid the connecting pipe 3 from loosening or displacement due to equipment vibration, thereby ensuring the continuity and stability of the dust collection process. One end of the telescopic pipe 33 is connected to the other end of the second pipe body 32, and the other end of the telescopic pipe 33 is connected to the inlet of the vacuum cleaner 2. The setting of the telescopic pipe 33 can adapt to different distances and angle changes between the suction head 1 and the vacuum cleaner 2, ensuring the tightness and reliability of the connection. Specifically, in this embodiment, the telescopic pipe 33 is an accordion pipe.

[0037] In this embodiment, during installation, after adjusting the angle of the drill rod 400 of the down-the-hole drill and fixing the frame 100, the locking nut on the second bolt 10 is loosened, allowing the collection box 4 and the vacuum cleaner 2 on it to rotate freely with the sliding seat 8. Then, the sliding seat 8 is slid along the sliding guide rail, placing the bottom of the collection box 4 on the ground. Finally, the locking nut is tightened to secure it, thus providing further support for the down-the-hole drill and ensuring its stable operation. When the down-the-hole drill starts working, the dust generated by the drill rod 400 during drilling will accumulate near the suction head 1. Since the suction part 102 of the suction head 1 has multiple suction holes 103, under the suction force of the vacuum cleaner 2, the dust enters the suction part 102 through the suction holes 103, and then is sucked into the vacuum cleaner 2 through the receiving part 101 and the connecting pipe 3. The vacuum cleaner 2 further transports the dust to the collection box 4, which is connected to its outlet, for storage.

[0038] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
