Abstract
Description
Technical Field
[0001] The utility model relates to an explosion-proof flushing shovel for mining. Background Art
[0002] When the floor of a coal mine tunnel or working face is uneven, it often needs to be leveled with a shovel. As the shovel scrapes for a long time, friction and heat are generated at the leading edge of the shovel, reducing its hardness and eventually causing it to become blunt and curled, making scraping even more difficult. Furthermore, when encountering hard sand and gravel, the leading edge of the shovel can produce sparks. If gas suddenly emerges at this time, it can easily cause a mine explosion, which is extremely dangerous. Summary of the Invention
[0003] The technical problem to be solved by the utility model is how to fill the above-mentioned gap in the prior art and provide a mining explosion-proof flushing shovel that is easy to take and put.
[0004] To address the aforementioned technical issues, the present explosion-proof mining flushing shovel comprises a shovel body 1 and a shovel handle 2. The shovel body 1 is fixed to the lower end of the shovel handle 2. The shovel body 1 or the lower portion of the shovel handle 2 is also equipped with a water spray pipe 3. This water spray pipe 3 is equipped with multiple nozzles 4 and a water inlet 5. The water inlet 5 is connected to a high-pressure water supply line via a hose 6. The water sprayed by the nozzles 4 is directed directly at the leading edge of the shovel body 1. This design not only reduces frictional heat generated at the leading edge of the shovel blade, maintaining a high hardness, but also effectively isolates and extinguishes any sparks that may occur at the leading edge of the shovel, reducing the risk of mine explosions. Furthermore, the water can also flush away any debris scooped up.
[0005] As an optimization, a pair of lugs 7 are respectively provided at the middle and rear parts of the shovel body 1, and a through hole 8 is respectively opened on each pair of lugs 7. A through hole 8 is opened at the lower end of the shovel handle 2, and is inserted into the lug 7 in the middle part of the shovel body 1, and a first fixing bolt 9 is passed through them together to hinge the shovel body 1 and the lower end of the shovel handle 2 together. A U-shaped splint 10 is also provided at the lower part of the shovel handle 2, and a through hole 8 is opened on the U-shaped splint 10. Two connecting plates 11 are further provided on both sides of the U-shaped splint 10, and multiple through holes 8 are opened on the two connecting plates 11. The through hole 8 at the lower end of the connecting plate 11 is opposite to the through hole 8 on the lug 7 at the rear part of the shovel body 1, and a second fixing bolt 12 is passed through them together. One of the through holes 8 on the U-shaped splint 10 is opposite to a through hole 8 on the upper part of the connecting plate 11, and a third fixing bolt 13 is passed through them together. With such a design, by passing the third fixing bolt 13 through the through hole 8 on the upper part of different connecting plates 11 and the through hole 8 on the U-shaped clamp 10, the U-shaped clamp 10 can be moved in a small range on the shovel handle 2 to adjust the angle between the shovel body 1 and the shovel handle 2 to adapt to users of different heights.
[0006] As an optimization, the shovel handle 2 in front of the U-shaped clamp 10 is further provided with a pair of lugs 7. Each pair of lugs 7 has a through hole 8. A short tube 14 extends outward from the inner wall of each through hole 8. The short tube 14 is provided with multiple slits 15 on the outside. The short tube 14 is also provided with external threads and a fastening nut 16. The slits 15 divide the outside of the short tube 14 into multiple curved splints 17. The water spray pipe 3 is passed through the two short tubes 14. The fastening nut 16 also has a tapered portion 18. The two fastening nuts 16 are screwed onto the external threads of the short tubes 14. The tapered portion 18 tightens the multiple curved splints 17 and the water spray pipe 3 together. With this design, loosening the fastening nut 16 allows the water spray pipe 3 to be rotated so that the water spray is always aimed at the front of the shovel body. Tightening the fastening nut 16 tightens the water spray pipe 3 to prevent it from loosening or rotating.
[0007] The explosion-proof flushing shovel for mining has the advantages of simple structure, convenient use, labor-saving, and less likelihood of generating sparks during use, and is suitable for use in underground coal mines. BRIEF DESCRIPTION OF THE DRAWINGS
