[0029] like Figures 1 to 4 As shown together, this embodiment provides a coal mine desilting equipment, which includes a crawler trolley assembly 1, a dirt storage bin 11 is fixed on the frame of the crawler trolley assembly 1, a feed bin 12 is fixed at the movable end of the hydraulic arm of the crawler trolley assembly 1, and the discharge port of the feed bin 12 is located above the dirt storage bin 11, a feed shovel bin 13 is welded at the feed port of the feed bin 12, and a connecting port 14 connected to the interior of the feed bin 12 is opened in the middle of the feed shovel bin 13 near the side of the feed bin 12, and a feed component is fixed in the inner cavity of the feed bin 12;

[0030] There are multiple high-pressure nozzles 2 and a rotating assembly 3. A hard pipe 21 is fixed at the feed port of the high-pressure nozzle 2, and the hard pipe 21 is installed on the movable end of the rotating assembly 3. A water tank 24 is fixed on the side of the feed bin 12 away from the feed shovel bin 13. An equalizing pipe 25 is fixed on the side of the feed bin 12 close to the feed shovel bin 13 through a pipe rack. A hose 22 is installed between the discharge end of the equalizing pipe 25 and the feed end of the hard pipe 21. A high-pressure pump 23 is fixed on the feed bin 12 and on the side of the water tank 24 close to the feed shovel bin 13. The water inlet end of the high-pressure pump 23 is connected to the water outlet end of the water tank 24, and the water outlet end of the high-pressure pump 23 is connected to the water inlet end of the equalizing pipe 25.

[0031] When cleaning silt, high-pressure water is sprayed from the high-pressure nozzle 2 onto the silt in front of the equipment to disperse the silt, and at the same time, the flushing range of the high-pressure nozzle 2 is adjusted horizontally and vertically to expand the dispersion range of the high-pressure nozzle 2, which is more conducive to effectively disperse the silt, disperse the lumps of silt into smaller pieces, avoid condensation, and is more conducive to absorption and treatment by the silt removal equipment, thereby improving the silt removal efficiency.

[0032] like Figures 1 to 2 As shown together, in this embodiment, the feeding assembly includes two driving rollers installed on both sides of the feeding bin 12, and a servo motor installed on the outer wall of the feeding bin 12, and the driving end of the servo motor is connected to the driving end of a driving roller, and a synchronous belt is installed between the two driving rollers, and a plurality of push plates are installed on the outer wall of the synchronous belt at equal intervals.

[0033] like Figures 1 to 2 As shown in the figure, in this embodiment, conveying blades 16 are rotatably installed on both sides of the feed shovel bin 13, and shaft brackets 15 are welded on both sides of the feed shovel bin 13 and the feed port 14, and one end of the conveying blade 16 is rotatably installed on the shaft bracket 15.

When the sludge is located inside the feed shovel bin 13, the hydraulic motors 17 on both sides are simultaneously When it is started, the hydraulic motor 17 will drive the conveying blades 16 on both sides to rotate simultaneously, so that the silt on both sides of the feed shovel bin 13 will continue to move toward the middle, which is conducive to promoting the silt inside the feed shovel bin 13 to quickly pass through the connecting material port 14 into the feed bin 12, avoiding the silt accumulating on both sides of the feed shovel bin 13 and not moving toward the middle, thereby improving the comprehensiveness and efficiency of dredging. In addition, when the conveying blades 16 come into contact with the silt, they help to crush the silt, making it easier to absorb and transport the silt.

[0034] like Figures 2 to 4As shown together, in this embodiment, the rotating assembly 3 includes a hollow frame 31 slidably mounted on the feed shovel bin 13 , and the interior of the hollow frame 31 is rotatably mounted with fixed sleeves 312 whose number is the same as the number of hard tubes 21 , and the hard tubes 21 are fixed inside the fixed sleeves 312 .

[0035] like Figure 4 As shown, in this embodiment, both sides of the fixed sleeve 312 are integrally formed with a flat end 311, and a mounting shaft 310 is fixed between the two adjacent flat ends 311. Both sides of the hollow frame 31 are rotatably mounted with a horizontal shaft, and one end of the horizontal shaft is connected to the flat end 311 fixed on the sidemost fixed sleeve 312. The two connected fixed sleeves 312 are linked by the mounting shaft 310, and driving one mounting shaft 310 is equivalent to driving all the mounting shafts 310 to rotate at the same time. Therefore, only one linear motor 313 is needed to drive all the high-pressure nozzles 2 to move, which reduces the production and use costs. The mounting shaft 310 is sleeved with a gear 39 A frame 36 is welded on the hollow frame 31 at a position opposite to the gear 39. A linear motor 313 is fixed inside the frame 36. A rack 38 meshing with the gear 39 is fixed at the movable end of the linear motor 313. Both ends of the frame 36 are provided with an inlet and outlet 37 for the rack 38 to pass through. The linear motor 313 reciprocatingly drives the rack 38 to move laterally. Under the meshing transmission action of the rack 38 and the gear 39, the mounting shaft 310 is driven to rotate reciprocatingly, thereby driving the high-pressure nozzle 2 to perform a longitudinal up and down reciprocating swing state, changing and expanding the spray range of the high-pressure nozzle 2, which is more conducive to a more comprehensive flushing treatment of the sludge.

[0036] like Figure 4 As shown, in this embodiment, slides 32 are fixed at both ends of the hollow frame 31 close to the feed shovel bin 13, two guide rails 33 are fixed on the top of the feed shovel bin 13, and the slides 32 slide on the guide rails 33 through the slide grooves opened at the bottom thereof, and a U-shaped connecting frame 34 is welded between the two slides 32, and an electric telescopic rod 35 is fixed to the feed shovel bin 13 through a pad, and the movable end of the electric telescopic rod 35 is connected to the U-shaped connecting frame 34, and the extension and contraction of the electric telescopic rod 35 simultaneously drives the two slides 32 to move back and forth horizontally through the U-shaped connecting frame 34, thereby driving the rotating assembly 3 and the high-pressure nozzle 2 installed inside the rotating assembly 3 to move, and changing and increasing its spray range from the lateral end of the high-pressure nozzle 2, thereby further improving the comprehensiveness of the high-pressure nozzle 2 in dispersing sludge.

[0037] When in use, the crawler trolley assembly 1 controls the feed shovel bin 13 to move, shoveling the silt into the feed shovel bin 13. The silt passes through the connecting port 14 and is fed into the feed bin 12 by the feeding assembly. The silt in the feed shovel bin 13 is continuously shoveled into the feed bin 12, and continuously moves inside the feed bin 12 and finally falls into the sewage storage bin 11.

[0038] When the sludge is inside the feed shovel bin 13, the hydraulic motors 17 on both sides are started at the same time, and the hydraulic motors 17 drive the conveying blades 16 on both sides to rotate simultaneously, so that the sludge on both sides of the feed shovel bin 13 is continuously moved toward the middle, which is conducive to promoting the sludge inside the feed shovel bin 13 to quickly pass through the connecting port 14 into the interior of the conveying bin 12;

[0039] When cleaning the silt, the high-pressure pump 23 draws water from the water tank 24 and delivers it to the inside of the equalizing pipe 25. The water in the equalizing pipe 25 flows to the inside of the high-pressure nozzle 2 through multiple hoses 22. The high-pressure nozzle 2 sprays high-pressure water onto the silt in front of the equipment to disperse the silt, making it easier to shovel and clean the silt through the feed shovel bin 13.

[0040] At the same time, the linear motor 313 reciprocatingly drives the rack 38 to move laterally. Under the meshing transmission action of the rack 38 and the gear 39, the mounting shaft 310 is driven to rotate reciprocatingly, thereby driving the high-pressure nozzle 2 to perform a longitudinal up and down reciprocating swing state, thereby changing and expanding the spray range of the high-pressure nozzle 2.

[0041] The extension and retraction of the electric telescopic rod 35 simultaneously drives the two slides 32 to move back and forth horizontally through the U-shaped connecting frame 34, thereby driving the rotating component 3 and the high-pressure nozzle 2 installed inside the rotating component 3 to move, thereby changing and increasing the spray range of the high-pressure nozzle 2 from the lateral end.

[0042] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
