when the drill bit works, the cooling liquid pipe 24 is always connected with external cooling liquid, then the cooling liquid in the cooling liquid pipe 24 enters the hollow drill rod 10 through the rotary joint 23 and is discharged through the cooling liquid hole 12 in the drill rod 10, and then the cooling liquid flows onto the drill bit 11 under the action of gravity to cool the drill bit 11;

before the drill bit 11 continues to descend and completely drills through the nut raw material, the sliding rod 29 on the air chamber 25 is in contact with the extrusion frame 31, the sliding rod 29 drives the piston 28 to move upwards under the extrusion of the extrusion frame 31, the piston 28 moves upwards to discharge gas in the air chamber 25 to the cooling liquid pipe 21, the pressure in the cooling liquid pipe 24 is increased due to the addition of the gas from the cooling liquid pipe 24, the discharge speed of the cooling liquid from the cooling liquid hole 12 under pressure is increased, and the cooling liquid pushes chips on the upper surface of the nut raw material to move towards two sides to play a role in cleaning the chips;

then the drilling rod 10 continues to descend, and then the screw tap 13 moves downwards and rotates and carries out the tapping to the hole that is bored by drill bit 11 on the nut raw and other materials, after the tapping finishes, sliding block 9 just is in the last state, then drill bit 11 upwards discharges, when drill bit 11 discharges completely and push down bucket 16 and just break away from spacing annular groove 33, the initiative driver plate 3 of intermittent type transport structure just in time stirs driven sheave 4, and then driven sheave 4 rotates and drives a belt pulley 5 and rotate, then repeats above-mentioned process and processes next nut raw and other materials.
