Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a simple drilling device for blasting engineering. Background Technology

[0002] Blasting engineering refers to a construction method that uses explosives to excavate earth and rock, and to demolish or destroy foundations, buildings, and structures. There are many types of explosives, and the most commonly used explosives in construction engineering include ammonium nitrate explosives, nitroglycerin explosives, and black powder. When installing explosives at a designated location, it is necessary to first use a drilling device to drill holes at the location where blasting is required, and then place the explosives in the holes for blasting operations.

[0003] Chinese Patent Publication No. CN216894239U discloses a simple drilling device for blasting engineering, including a trolley and an internal combustion drilling machine. Beneficial effects: This utility model uses a housing, a slider, and a trolley. For horizontal drilling, the second insert on the outer wall of the housing can be inserted into the insertion hole to fix the housing and the internal combustion drilling machine. Turning the handle drives the screw to rotate, thereby moving the slider up and down to adjust the height of the internal combustion drilling machine. Feeding is achieved by pushing the trolley. For vertical drilling, the first insert can be inserted into the insertion hole to vertically fix the housing and the internal combustion drilling machine. Turning the handle drives the screw to rotate, thereby moving the slider up and down for feeding. This device facilitates both vertical and horizontal drilling, is easy to adjust and use, and the trolley eliminates the hassle of hand-operating the drilling machine, making operation more labor-saving and significantly improving drilling efficiency.

[0029] Please see Figure 1-5 A simple drilling device for blasting engineering includes a housing 1. A connecting column 3 is fixedly installed on the right side of the housing 1. The connecting column 3 has a connecting movable cavity 19 and a mounting cylinder 6 inside. A connecting cylinder 4 is movably installed inside the connecting movable cavity 19. A connecting cavity 20 is opened inside the connecting cylinder 4. The connecting movable cavity 19 and the connecting cavity 20 are connected. A vent pipe 10 is installed on the right side of the connecting cylinder 4. A through pipe 18 is installed on the left side of the connecting column 3.

A rotating cylinder 7 is installed on the right side of the mounting cylinder 6. A connecting cylinder 6 is installed inside the rotating cylinder 7. A connecting bearing 25 is used; the rotating cylinder 7 is movably connected to the mounting cylinder 6 via the connecting bearing 25. A first handle 9 is installed on the top of the rotating cylinder 7. An air passage 13 is opened inside the first handle 9, and an air inlet and outlet hole 8 is opened on the outer surface of the first handle 9. The air inlet and outlet hole 8 are evenly distributed along the outer surface of the first handle 9, and the air inlet and outlet hole 8 are connected to the air passage 13. The air passage 13 is connected to the connecting cavity 20 via the air pipe 10. A partition 12 is installed inside the housing 1. A connecting pipe 14 passes through the interior of the partition 12. A bidirectional rotating fan 15 is installed inside the partition 12. A heat dissipation hole 2 is provided on the outer surface of the housing 1. A second handle 11 is installed on the left side of the housing 1.

[0030] In this implementation scheme: by setting a rotatable and adjustable first grip 9, the angle and direction of the first grip 9 can be adjusted, making it more convenient for the user to operate; at the same time, by setting the air inlet and outlet 8 on the first grip 9 and the second grip 11, in conjunction with the bidirectional rotating fan 15, the heat generated by the motor 26 during operation is discharged through the air inlet and outlet 8 when the weather is cold, warming the user's hands; when the weather is hot, outside air is allowed to enter the housing 1 through the air inlet and outlet 8 to cool the motor 26, thereby increasing the air flow at the first grip 9 and the second grip 11, cooling the user's hands, preventing sweating, and thus greatly improving the comfort of using the drilling device.

[0031] Furthermore:

[0032] In an optional embodiment, a limiting groove 24 is formed on the outer surface of the mounting cylinder 6, and the limiting groove 24 is evenly distributed along the outer surface of the mounting cylinder 6.

[0033] In this embodiment, by opening multiple limiting grooves 24 at specific locations, the first grip 9 can have multiple adjustable positions in multiple directions.

[0034] Furthermore:

[0035] In an optional embodiment, a limiting movable hole 22 is formed in the inner wall of the rotating cylinder 7, and a limiting rod 5 corresponding to the limiting groove 24 passes through the limiting movable hole 22. A return spring 23 is installed on the outside of the limiting rod 5, and the limiting rod 5 is elastically connected to the rotating cylinder 7 through the return spring 23.

[0036] In this implementation scheme, the adjustment of the first grip 9 is made more convenient and quick by the cooperation of the limiting rod 5 and the return spring 23 with the limiting groove 24.

[0037] Furthermore:

[0038] In an optional embodiment, a groove 21 is formed on the inner wall and outer surface of the connecting cylinder 4.

[0040] Furthermore:

[0041] In an alternative embodiment, a motor 26 is mounted on the right side of the partition 12, and a drill barrel 27 is threaded onto the output end of the motor 26.

[0042] Working principle: When using this simple drilling device for blasting engineering, first pull the limiting rod 5 so that one end of the limiting rod 5 exits from the limiting groove 24. Then rotate the first handle 9 so that the first handle 9 rotates through the rotating cylinder 7 and the connecting bearing 25 to rotate the first handle 9 to the appropriate direction. Then release the limiting rod 5, and the limiting rod 5 is pushed into the corresponding limiting groove 24 by the elastic force of the return spring 23. Secondly, during the rotation of the first handle 9, the vent pipe 10 drives the connecting cylinder 4 to rotate with the first handle 9 inside the connecting movable cavity 19 through the connecting ball 16 and the groove 21. Thirdly, when using it in cold weather, the controller controls the bidirectional rotating fan 15 to blow air to the left. The outside air enters the shell through the heat dissipation hole 2 under the guidance of the bidirectional rotating fan 15. Inside the housing 1, the heat generated by the motor 26 during operation is carried away and enters the connected movable cavity 19 through the connecting pipe 14 and the through pipe 18. Then, it enters the air passage 13 through the connecting cavity 20 and the vent pipe 10 and is discharged from the air inlet and outlet 8. Similarly, hot air is also blown out from the second grip 11 to warm the hand. When used in hot weather, the bidirectional rotating fan 15 is controlled by the controller to blow air to the right. The outside air enters the housing 1 through the air inlet and outlet 8 under the guidance of the bidirectional rotating fan 15, and carries away the heat generated by the motor 26 during operation and is discharged from the heat dissipation hole 2. The bidirectional rotating fan 15, model HTF, is existing technology and can control and change the airflow direction. Its size can be adjusted according to the actual use. This is the working principle of the simple drilling device for blasting engineering.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
