Description

Technical Field

[0001] This utility model relates to the field of blasting construction technology, specifically to an atomizing dust suppression device for open-pit mine blasting construction. Background Technology

[0002] Currently, in open-pit mine blasting operations, in order to reduce the harm of dust generated during the blasting process to the surrounding environment and personnel health, mist cannons are usually used for dust suppression. Since the construction site after blasting is usually quite dusty, the air inlet of the existing mist cannons is equipped with dustproof nets to intercept dust and debris. However, the dust that is intercepted adheres to the dustproof nets and causes blockage of the air inlet holes, affecting the atomization dust suppression effect. Manual cleaning is required, which is quite cumbersome. In view of this, this case was developed through in-depth research on the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an atomizing dust suppression device for open-pit mine blasting operations, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A dust suppression device for open-pit mine blasting includes a dustproof net installed on the air inlet end of the fog cannon barrel of the fog cannon body.

An annular guide rail is provided on the annular seat. A rotating ring is rotatably mounted on the annular guide rail. A gear ring is fixedly mounted on the outside of the rotating ring. A drive gear is provided at the output end of the rotary drive assembly. The drive gear meshes with the gear ring. Two supports are symmetrically arranged on the rotating ring. A locking and limiting component is provided on the supports. A portal frame is inserted into the supports. A brush is installed at the crossbeam position of the portal frame. The brush head is in contact with the outer end face of the dustproof net.

[0005] The aforementioned gears and gear rings are all fitted with dustproof shells on their outer sides, and the dustproof shells are provided with elastic sealing rings at the contact positions with the rotating rings.

[0006] The aforementioned rotary drive assembly includes a mounting base, a servo motor, a reducer, and a fixed shaft. The mounting base is disposed on the side wall of the fog cannon and located on one side of the annular seat. The reducer is disposed on the mounting base and its input end is connected to the drive end of the servo motor. One end of the fixed shaft is connected to the output end of the reducer, and the other end is fixedly connected to the drive gear.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Refer to the appendix of the instruction manual Figure 1-5 As can be seen, this application specifically designs a dust suppression device for open-pit mine blasting operations, including a dustproof net 2 installed on the air inlet end of the fog cannon 1 of the fog cannon body, an annular seat 3 installed on the outer wall of the air inlet end of the fog cannon 1, a rotary drive component installed on one side of the annular seat 3, an annular guide rail 4 installed on the annular seat 3, a rotating ring 5 rotatably mounted on the annular guide rail 4, a gear ring 6 fixedly mounted on the outside of the rotating ring 5, a drive gear 7 installed at the output end of the rotary drive component, the drive gear 7 meshing with the gear ring 6, a dustproof shell 11 fastened to the outside of both the gear and the gear ring 6, an elastic sealing ring 12 provided at the contact position between the dustproof shell 11 and the rotating ring 5, two supports symmetrically arranged on the rotating ring 5, and a locking and limiting component provided on the supports 8. The device incorporates a gantry frame 9, with brushes 10 mounted on the crossbeam of the gantry frame 9. The brush head of the brushes 10 is in contact with the outer end face of the dustproof net 2. The existing fog cannon body 1 is modified by using a rotary drive assembly as the power source, which drives the gear ring 6 through the drive gear 7. The gear ring 6 then drives the rotating ring 5 on the annular guide rail 4 to rotate. The rotation of the rotating ring 5 causes the support 8 on the rotating ring 5 to rotate, which in turn causes the gantry frame 9 on the support 8 to rotate. During the rotation of the gantry frame 9, the brushes 10 on it clean the dustproof net 2, thereby removing the dust attached to the dustproof net 2. The structure is simple and highly automated. It only requires periodic removal of the gantry frame 9 to clean or replace the brushes 10.

[0019] In the specific implementation process, the above-mentioned rotary drive assembly includes a mounting base 13, a servo motor 14, a reducer 15, and a fixed shaft 16. The mounting base 13 is set on the side wall of the fog cannon 1 and located on one side of the annular seat 3. The reducer 15 is set on the mounting base 13 and its input end is connected to the drive end of the servo motor 14. One end of the fixed shaft 16 is connected to the output end of the reducer 15, and the other end is fixedly connected to the drive gear 7. The rotary drive assembly is fitted with a protective shell 17. In use, the servo motor 14 and the reducer 15 cooperate to realize the rotation control of the fixed shaft 16. The rotation of the fixed shaft 16 drives the drive gear 7 to rotate. The rotation of the drive gear 7 drives the gear ring 6 that meshes with it to rotate. The rotation of the gear ring 6 drives the rotating ring 5 to rotate. During the rotation of the rotating ring 5, the gantry frame 9 installed on its support 8 rotates synchronously. During the rotation of the gantry frame 9, the brush 10 on it cleans the dustproof net 2, thereby realizing the automatic cleaning operation of the dustproof net 2.

[0020] In the specific implementation process, the above-mentioned locking and limiting components include a threaded seat 18 and a locking bolt 19. Both ends of the portal frame 9 are provided with legs 20, which are inserted into the support 8. The side wall of the leg 20 is provided with a positioning threaded hole. The threaded seat 18 is set on the side wall of the support 8. The locking bolt 19 is screwed into the threaded seat 18 and its lower end extends into the positioning threaded hole. The threaded cap of the locking bolt 19 is welded with a butterfly knob 21. In use, the legs 20 at both ends of the portal frame 9 are inserted into the corresponding support 8. The butterfly knob 21 on the locking bolt 19 is rotated to insert the locking bolt 19 into the positioning threaded hole on the leg 20, thereby realizing the limiting and locking of the portal frame 9. When it is necessary to clean or replace the brush 10, the butterfly knob 21 can be rotated in the opposite direction to remove the locking bolt 19 and pull out the leg 20 to realize the overall disassembly and assembly of the portal frame 9. The structure is simple and the operation is convenient.
