As shown in fig. 2-4, shake board 5b3 surface and be equipped with a plurality of sand grips g, sand grip g is the fork form of having the interval and installs in shaking board 5b3 surface, sand grip g is connected through the electric welding with shaking board 5b3, is favorable to realizing doing the jolt ramming to the well drilling inside wall after the drilling and handles, avoids the pore wall on upper portion to last drilling in lower part simultaneously, receives the effect of its vibrations, leads to upper portion to appear becoming flexible, produces and collapses.

In conclusion, the raised strips g on the surface of the vibrating plate 5b3 are used for rhythmically compacting the inner wall of the mine hole under the action of the special-shaped wheel 5b2, so that the phenomenon that the mine hole is loosened under the action of vibration residual waves of the lower drill hole to cause collapse is avoided.

The specific realization principle is as follows: the loop bar 5b1 is rotary motion and drives the special-shaped wheel 5b2 synchronous motion along with it under the effect that auger stem 5a is rotatory, the in-process that ejector pin 5b5 collided each other with special-shaped wheel 5b2, then promote the board 5b3 looks outside extension removal that shakes that links to each other with it, laminate with the downthehole wall, and under the mating reaction of sand grip g, do the compaction effect of compacting to the downthehole inside wall, in order to avoid it under the trompil shock wave influence of lower auger stem 5a, the phenomenon that has the wall to become flexible and lead to collapsing appears.

This embodiment is in order to solve when carrying out the mining, need to be beaten under its underground, and the underground space is big more the breakage just also big to the geology, when utilizing drilling equipment to drill, because drilling equipment is vertical rotation drilling, its downthehole ripple wall crack phenomenon that has the drilling equipment oscillation production of easily appearing, it is possible to discover the collapse phenomenon to be careless, so utilize the mutual cooperation of the board of shaking that is equipped with and the special-shaped wheel and the sand grip that is equipped with on the surface, the well drilling inside wall after the drilling is done rhythmically and is done the jolt real processing, avoid the pore wall on upper portion to continue drilling in the lower part simultaneously, receive the effect of its vibrations, lead to hole upper portion to appear becoming flexible under the vibrations afterwave of auger stem, thereby take place to produce the collapse phenomenon.

Second embodiment:

as shown in fig. 1, 2, 5 and 6, the invention provides a technical scheme of a synchronous drilling system and method special for a mine:

As shown in fig. 5-6, the righting structure 5c includes a frame 5c1, a separation screen 5c2, an overflow ring 5c3, an airbag cover 5c4, and a pull rod 5c5, wherein the separation screen 5c2 is disposed on the lower surface of the frame 5c1 and connected thereto by electric welding, the overflow ring 5c3 is mounted on the inner side surface of the frame 5c1 and is an integrated structure, the airbag cover 5c4 is disposed on the inner side of the overflow ring 5c3 and is connected to the top rod 5b5 by the pull rod 5c5, and the lower surface of the airbag cover 5c4 is connected to the separation screen 2 by gluing, which is beneficial to ensure the actual drilling depth of the auger stem 5 a.

As shown in fig. 5-6, the inner side surface of the overflow ring 5c3 is provided with a plurality of soft boards x which are installed in a staggered manner at intervals, and the soft boards x are vertically connected with the overflow ring 5c3 through electric welding, so as to be beneficial to assisting in loosening and falling off the soil adhered to the surface of the auger stem 5 a.

As shown in fig. 5-6, the soft plate x has a pointed cone-shaped structure, and the length of the intersection of the soft plate x and the section of the auger stem 5a is 1/3 times of the length of the soft plate x, so that soil with the property of laterite adhered to the surface of the auger stem 5a can be removed, and the actual drilling depth and the expected drilling depth are shallow when the soil is adhered to the surface of the auger stem 5 a.

In summary, the air bag sleeve 5c4 and the soft board x are arranged to strip the soil adhered to the surface of the auger stem 5a, so as to avoid the actual drilling depth and the expected depth being shallow, and the auger stem 5a being stuck by harder rocks.

The specific realization principle is as follows: the air bag sleeve 5c4 synchronously pulls along with the ejector rod 5b5 under the action of the pull rod 5c5 to generate air flow, the x arranged on the inner side of the overflow ring 5c3 is contacted with the auger stem 5a under the action of rotation of the auger stem 5a, so that the soil adhered to the surface of the auger stem 5a due to different soil qualities is loosened to avoid the inconsistency of the opening depths, and the air flow generated by pulling through the air bag sleeve 5c4 is output to the outside under the action of the overflow ring 5c3 and the isolation screen plate 5c2, so that the loosened soil is subjected to falling treatment to avoid the phenomenon that the auger stem 5a is subjected to false drilling due to the adhered soil.

This embodiment is comparatively obvious for solving because of mine soil layering, then can meet harder stratum in deepening more, equipment is when rather than colliding the drilling, it has appeared by the phenomenon of harder rock card shell, thereby lead to equipment to stop drilling, rock by a wide margin appears, produce unnecessary injury, so utilize the gasbag cover that is equipped with under the pulling of jolt ramming mechanism and the interact of pull rod, realize doing the effect of eliminating to the soil of spiral drill rod surface adhesion laterite type nature, in order to avoid it to have soil at the surface adhesion, cause actual drilling depth and predicted depth shallower, simultaneously because of the difference of mine lower floor soil, when touchhing harder stratum, then can go out the effect of having a card shell, thereby lead to spiral drill rod to stop drilling.
