Detailed ways

Accompanying drawing is a kind of concrete embodiment of the present invention, and this embodiment drilling rod 2 lower end is provided with first bar 22, and first bar upper left end is provided with counterweight 1, and first bar right upper end is provided with motor 18, and motor right end is provided with There is a first sprocket 19, the first sprocket is connected to the second sprocket 21 by a drive chain 20, the second sprocket left end is provided with a third bar 12, and the left and right ends of the third bar are respectively provided with a third cover 23, The two third sets are respectively fixed on the first side bar 3 and the second side bar 13, and the first wheel 8 and the second wheel 11 are arranged in the middle of the third bar; eight teeth 7 are arranged on the first wheel, which mesh with the second side bar. Nine teeth on a guide rod 4, the first guide rod is respectively provided with a first cover 5 up and down, the first cover on the upper side is fixed on the second rod 6, the first cover on the lower side is fixed on the fourth rod 14, the first The upper end of the guide rod is provided with a stop iron 17, the lower end of the first guide rod is fixed on the rectangular arm 24, and the rectangular arm is fixed on the first square hammer 15; Nine teeth, the second guide rod is provided with a second set 9 above and below, the second set on the upper side is fixed on the second rod, the second set on the lower side is fixed on the fourth rod, and the upper end of the second guide rod is provided with an iron stopper. The lower end of the second guide rod is fixed on the second square hammer 16; the left and right ends of the first rod, the second rod, and the fourth rod are respectively fixed on the first side rod and the second side rod.

The rectangular arm of the first square hammer can move up and down in the rectangular hole of the second square hammer, and the second square hammer can move up and down in the hole in the middle of the first square hammer.

When the teeth on the first wheel drive the teeth on the first guide rod to pull the first square hammer to move upward, the teeth on the second wheel break away from the teeth on the second guide rod, and the second square hammer moves downward; When the teeth on the first wheel drive the teeth on the second guide rod to pull the second square hammer to move upward, the teeth on the first wheel break away from the teeth on the first guide rod, and the first square hammer moves downward.

When the present invention works, the motor drives the first wheel and the second wheel to rotate through the first sprocket, the transmission chain, the second sprocket, and the third rod, and the places where the first wheel and the second wheel have teeth drive the square hammer to move upward. Where there are no teeth, the square hammer falls naturally. In this way, the first square hammer and the second square hammer move upwards alternately, and then fall alternately to make holes.
