[0028] The protection structure includes a protection frame 20. The protection frame 20 is arranged on the top of the main body 1. A second hydraulic push rod 21 is installed in the middle part of the top of the main body 1. The output end of the second hydraulic push rod 21 is connected to the bottom of the protection frame 20. Rotating plates 22 are hinged on both sides of the protection frame 20. The inside of the protection frame 20 is hollow. Connection components are arranged at the four corners of the bottom of the protection frame 20. Support columns 23 are arranged at the four corners of the top of the main body 1. Plug blocks 24 are arranged at the tops of the support columns 23. The connection components are vertically located corresponding to the positions of the support columns 23, and the bottom of the connection components is inserted and connected with the plug blocks 24 at the tops of the support columns 23.
[0029] The connection component includes a connection block 25. The connection block 25 is installed at the four corners of the bottom of the protection frame 20. A second electric push rod 26 is arranged on the lower side of the connection block 25. The output end of the second electric push rod 26 is connected to a push block 27.
[0030] Preferably, collection hoppers 28 are arranged on both sides of the main body 1. The bottom of the collection hopper 28 is connected to a conveying pipe 29.
[0031] In addition, collection boxes 30 are arranged on both sides of the water storage tank 5. The collection boxes 30 are communicated with the conveying pipe 29;
[0032] A row of spray nozzles 31 is evenly arranged at the front end of the protection frame 20. The spray nozzles 31 are communicated with the inside of the protection frame 20;
[0033] A filtering device 32 is provided at the connection between the conveying pipe 29 and the collecting hopper 28;
[0034] The pushing block 4 is integrally an isosceles trapezoid. One side of the transmission block 14 is in close contact with one side of the pushing block 4. There is an inclined surface on one side of the transmission block 14, which is matched with one side of the pushing block 4;
[0035] Fixing bolts are provided on both the left and right sides of the base 2. The main body 1 can be installed on one side of the rock drilling jumbo through the fixing bolts on any side of the base 2. Each rock drilling jumbo can be equipped with an independent hydraulic control mechanism on either side or on both sides.
[0036] It should be noted that before the rock drilling jumbo works, the main body 1 is installed on one side of the rock drilling jumbo through the fixing bolts on both sides of the base 2. At this time, the protective frame 20 is in a contracted state. When the rock drilling jumbo performs underground construction and rock drilling operations, the second hydraulic push rod 21 operates to lift the entire protective frame 20 and separate the bottom of the connecting block 25 from the plug 24 at the top of the support column 23. At the same time, the second electric push rod 26 operates, and the rotating plate 22 can be lifted through the push block 27; then the first hydraulic push rod 3 contracts, and the first hydraulic push rod 3 drives the pushing block 4 to move forward. And the first electric push rod 9 located on one side inside the main body 1 operates, and the moving frame 6 can be pushed to move horizontally along the limit sliding groove 7. Since a rack 8 is embedded on one side of the moving frame 6 and the rack 8 meshes with the gear 13, during the horizontal movement of the moving frame 6, the rotating shaft 11 will be driven to rotate by the gear 13, so that the drainage frame 12 can be rotated out from the storage groove 10. And when the moving frame 6 moves to the end of the limit sliding groove 7, the gear 13 just rotates 90 degrees. At this time, the drainage frame 12 changes from horizontal to vertical.
[0037] After the protective frame 20 is unfolded and lifted and the drainage frame 12 becomes vertical, the first water pump 15 at the front end of the water storage tank 5 operates, and the dust suppression water can be pumped from the inside of the water storage tank 5 and transported through the three-way pipe 16, the fixed pipe 17 and the hose 18 and sent into the drainage frame 12. Since the drainage frame 12 needs to rotate as a whole, the hose 18 can always keep the water storage tank 5 and the inside of the drainage frame 12 connected. At the same time, the second water pump 19 operates, and the dust suppression water can be pumped and sent into the protective frame 20, and then sprayed out through the nozzles 31 at the front end of the protective frame 20. Cooperating with the drainage frame 12, multi-directional water spraying and dust suppression operations can be carried out on both sides of the rock drilling jumbo. And because when the rock drilling jumbo is under construction, falling stones and soil blocks may appear on the surrounding walls, the protective frame 20 and the rotating plate 22 can protect the drainage frame 12 on the upper side of the main body 1.
[0038] Meanwhile, when water is sprayed on the drainage rack 12, some of the dust suppression water will be spilled and wasted. The collecting hopper 28 will collect the spilled water and send it into the interior of the collecting box 30 through the conveying pipe 29, which is convenient for subsequent recycling. At the same time, the filtering device 32 can simply filter the collected water for subsequent use.
[0039] After the operation of the rock drilling jumbo is completed, the first electric push rod 9 contracts, and at the same time, the hydraulic push rod operates. Through the cooperation of the transmission block 14 and the pushing block 4, the movable frame 6 can be reset. Through the transmission cooperation of the rack 8 and the gear 13, the drainage rack 12 can be screwed back into the storage groove 10. At the same time, the second electric push rod 26 contracts, and the rotating plate 22 and the protective frame 20 are reset.
[0040] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to some parts by those skilled in the art of the present technology all reflect the principles of the present invention and are within the protection scope of the present invention.
