step three: as shown in fig. 1, 2 and 4, with the feeding mechanism and the crushing mechanism continuously feeding the filling material to the lower end of the inside of the drill hole, and under the continuous hammering and compacting action of the outer tube 15, because the relative positions of the motor 1 and the sleeve ring 20 are always kept unchanged, when the filling material at the bottom of the drill hole is compacted and the height of the filling material rises, the reaction force to the outer hammer 18 is increased, so that the outer tube 15 moves up relative to the sleeve ring 20 when the sleeve ring 20 drives the outer tube 15 to move down, the reaction force causes the outer tube 15 to move up relative to the sleeve ring 20, the teeth 25 move up relative to the sleeve ring 20 when the outer tube 15 moves up relative to the sleeve ring 20, the teeth 25 move up through the action of the wedge surfaces and the wedge surfaces at the ends of the pins 24, and a thrust directed to the inside of the through groove 21 is applied to the pins 24, so that the pins 24 move towards the inside of the through groove 21, and further avoid the teeth 2, so that the, after the tooth 25 rises and is dislocated with the pin rod 24, the pin rod 24 moves towards the outer side of the through groove 21 under the reaction force of the spring I22 and is abutted against the next tooth 25, and the process is repeated, so that the outer pipe 15 continuously and automatically moves upwards while automatically feeding, the outer pipe 15 does not need to be taken out for multiple times and then the filling depth is measured, only the height of the outer pipe 15 which rises compared with the initial state is measured, or the length scale is printed on the outer side wall of the outer pipe 15, and the outer pipe can be directly read, so that the time and labor are saved, and the working efficiency is improved;

from the above, when the component force of the reaction force of the filling material in the drill hole on the outer pipe 15 to the pin rod 24 through the teeth 25 is greater than the thrust of the spring one 22 to the pin rod 24, the outer pipe 15 can be lifted relative to the ring sleeve 20, so that the thrust of the spring one 22 to the pin rod 24 can be adjusted through the bolt 23 to adjust the compaction degree of the outer pipe 15 to the filling material filled at the bottom of the drill hole, that is, the larger the thrust of the spring two 22 to the pin rod 24 is, the larger the compaction degree of the outer pipe 15 to the filling material filled at the bottom of the drill hole is, and the smaller the compaction degree of the filling material is, so that the compaction degree of the filling material;

it should be noted that when the outer tube 15 does not rise relative to the ring sleeve 20, the ring sleeve 20 drives the outer tube 15 to move up, the ring sleeve 20 and the cantilever 10 rise synchronously, that is, the ring sleeve 20 and the cantilever 10 are separated from the corresponding first touch switch 8 and the corresponding second touch switch 9 synchronously, and when the ring sleeve 20 drives the outer tube 15 to fall, the ring sleeve 20 and the cantilever 10 are synchronously contacted with the corresponding first touch switch 8 and the corresponding second touch switch 9 synchronously, in this case, the controller controls the cylinder 5 not to work, that is, the rack one 7 is kept still;

when the outer pipe rises relative to the ring sleeve 20, the cantilever 10 rises relative to the ring sleeve 20 synchronously, namely when the ring sleeve 20 touches the first touch switch 8, the cantilever 10 cannot touch the second touch switch 9, and when the cantilever 10 moves upwards relative to the ring sleeve 20, under the transmission action of the first rack 7, the second gear 11 and the second rack 12, the inner pipe 14 rises relative to the outer pipe 15, so that the inner hammer 16 rises relative to the hammer plate 17, further the inner hammer 16 cannot contact the hammer plate 17, namely the filling material falling on the hammer plate 17 cannot be hammered and crushed, the operation of the whole equipment is influenced, at the moment, the controller controls the cylinder 5 to work, the piston rod of the cylinder 5 drives the first rack 7 to move upwards for a certain distance after the cylinder 5 works, so that the second touch switch 9 is synchronously driven to move upwards until the second touch switch 9 can touch the cantilever 10, and the outer pipe 15 moves upwards relative to the ring sleeve 20, still can make cantilever 10 touch with touch switch two 9 when ring cover 20 touches with touch switch 8, in the ascending in-process of rack 7, drive gear 11 clockwise rotation to drive rack two 12 and descend, and then make inner tube 14 and interior tup 16 move down relatively outer tube 15, thereby keep the contact of interior tup 16 and hammer leaf 17 not influenced by the ascending of outer tube 15, and then guarantee the inside filling effect of drilling.
