[0008] Figure 1 This is a schematic diagram of the structure of the utility model for the punching equipment used in coal mining;
[0009] Figure 2 The utility model is a schematic diagram of the structure of the punching equipment used in coal mining.
[0010] In the figure: 1. low-pressure impactor, 2. anti-dropping fixing sleeve, 3. impact drill bit, 4. crushing tool, 5. arc-shaped sliding groove, 6. arc-shaped sliding connecting piece, 7. connecting baffle, 8. large-pitch tooth groove, 9. rotating screw, 10. rotating teeth. DETAILED DESCRIPTION
[0011] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0012] like Figure 1-Figure 2 As shown, a punching device for coal mining comprises a low-pressure impactor 1, an anti-slipping fixing sleeve 2, an impact drill bit 3, a crushing tool 4, an arc-shaped sliding groove 5, an arc-shaped sliding connecting piece 6, a connecting baffle 7, a large-tooth serrated groove 8, a rotating screw 9, and a rotating tooth 10. The front end of the low-pressure impactor 1 is equipped with an anti-slipping fixing sleeve 2, the front end of the anti-slipping fixing sleeve 2 is equipped with an impact drill bit 3, and the front end of the impact drill bit 3 is equipped with six crushing tools 4 at equal intervals. The left and right sides of the anti-slipping fixing sleeve 2 are provided with arc-shaped sliding grooves 5, the left and right sides of the rear end of the impact drill bit 3 are equipped with arc-shaped sliding connecting pieces 6, and the impact drill bit 3 is connected to the impact drill bit 3 through the two sides. The arc-shaped sliding connecting piece 6 is installed in the arc-shaped sliding grooves 5 on both sides of the anti-slipping fixing sleeve 2, and the arc-shaped sliding connecting piece 6 is installed behind the arc-shaped sliding grooves 5. The arc-shaped sliding connecting piece 6 is connected to the blocking pieces 7 on both sides of the rear end through screws. A large tooth sawtooth groove 8 is provided in the center of the anti-slipping fixing sleeve 2. A rotating screw 9 is installed in the impact drill bit 3, and the rotating screw 9 is installed in the large pitch tooth groove 8. A rotating tooth 10 is installed in the center of the front end of the impact drill bit 3.
