Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 and 2, an apparatus for ground drilling to achieve separation of drilled soil is applied to a ground 1 to be constructed, and the ground 1 to be constructed has been inserted into a steel casing 2, and soil enclosed in the steel casing 2 is formed into soil 1a to be excavated. Before the drilling tool is used, the steel casing 2 needs to be driven into the ground 1 to be constructed by means of external equipment, so that soil 1a to be excavated, which needs to be excavated, is surrounded in the steel casing 2 by means of the steel casing 2, and a drill bit 4 extends into the drilled soil from the steel casing 2.
The apparatus comprises:
the movable splicing type vehicle body 5 is provided with four groups of shielding pushing assemblies which independently move horizontally, and when the movable splicing type vehicle body 5 is unfolded around the periphery of the exposed part 2a of the steel casing 2 exposed out of the ground 1 to be constructed, the four groups of shielding pushing assemblies complete blocking or unblocking of a pipe orifice above the exposed part 2a in a centripetal gathering or outwards poking mode. That is, when the four sets of shielding pushing assemblies gather centripetally to the extreme state, the four sets of shielding pushing assemblies are spliced together, so that the pipe orifice above the exposed part 2a is sealed and blocked, thus external soil cannot enter the steel casing 2 from the pipe orifice above the exposed part 2a, and the point is one of important measures for ensuring the separation of subsequent drilled soil; after the drilled soil is separated, the separated soil falls above the four groups of shielding pushing assemblies, and the four groups of shielding pushing assemblies move outwards in a poking-out mode, so that a pipe orifice above the originally blocked exposed part 2a is opened again for the drill bit 4 to enter again and drill; the four groups of shielding pushing assemblies move outwards to push away soil in a direction away from the steel casing 2, so that the soil is guaranteed not to be accumulated around the steel casing 2, and the pushed away soil can be conveyed into a muck truck or other storage containers by means of external equipment such as a bucket or a belt conveyor.
The passive rotary stripper is configured to be coaxially distributed above the steel casing 2 and at a certain height from the upper end of the steel casing 2, the height space is used for accommodating the lifting drill bit 4 and four groups of shielding and pushing assemblies moving horizontally, and the two groups of shielding and pushing assemblies do not interfere with each other, the rotating shaft 3 of the drill bit 4 penetrates through the passive rotary stripper, and the helical blade 4a does not rotate when the drill bit 4 is lifted upwards so as to force the passive rotary stripper to rotate around the helical blade 4a, so that soil remained on the helical blade 4a is stripped. The passive rotary stripper adopted by the invention is driven to rotate by the upward or downward movement of the drill bit 4, because when the spiral blade 4a of the drill bit 4 contacts the passive rotary stripper, the force exerted by the spiral blade 4a on the passive rotary stripper drives the passive rotary stripper to rotate, and for the drill bit, the passive rotary stripper does not rotate in the process of contacting with the passive rotary stripper, so that the passive rotary stripper is matched with the upward lifting movement of the drill bit 4 by the rotation of the passive rotary stripper, so that the passive rotary stripper gradually moves along the spiral blade 4a in the rotating process, and the soil remained on the spiral blade 4a can be stripped.
When the spiral blade 4a is lifted upwards by the rotating shaft 3 and approaches to the passive rotary stripper, the four groups of shielding pushing assemblies seal the pipe orifice above the exposed part 2a by centripetal gathering, and the stripped soil is shunted to the periphery along the four groups of shielding pushing assemblies. Because the passive rotary stripper is positioned above the steel casing 2, the soil can fall downwards under the dead weight after the passive rotary stripper strips the soil remained on the spiral blade 4a, and at the moment, the pipe orifice above the exposed part 2a is blocked by four groups of blocking pushing assemblies, so that the soil is prevented from falling into the steel casing 2 again, and the smooth operation of drilling is ensured; with the help of the blocking operation, the peeled soil is shunted to the periphery along the four groups of shielding pushing assemblies, and the accumulation around the steel casing 2 is avoided.
As shown in fig. 1 to 3, the passive rotary stripper includes a fixed sleeve 8, a movable sleeve 10 rotatably connected in the fixed sleeve 8, and the movable sleeve 10 is formed at a middle portion thereof as a hollow structure through which the rotating shaft 3 passes, the hollow structure having a scraping tongue 11 protruding toward a central axis direction and matching a shape of a spiral groove formed by the spiral blade 4 a. According to the passive rotating stripper, a power source is not required to be arranged independently, after the scraping tongue 11 contacts the spiral blade 4a, the spiral blade 4a continuously ascends, so that the scraping tongue 11 is driven to rotate, and the scraping tongue 11 sequentially peels off the residual soil along the spiral groove of the spiral blade 4 a.
As shown in fig. 4, the size of the scraping tongue 11 is adapted to the groove width d of the spiral groove formed by the spiral blade 4 a.
As shown in fig. 3, 5 and 7, the movable split joint type vehicle body 5 includes a fixed half vehicle body 5a and a movable half vehicle body 5b horizontally hinged with an end of the fixed half vehicle body 5a, the movable half vehicle body 5b can surround the steel casing 2 with the fixed half vehicle body 5a from the periphery after horizontally rotating relative to the fixed half vehicle body 5a, and four groups of independent horizontally moving shielding pushing assemblies are correspondingly installed on the fixed half vehicle body 5a and the movable half vehicle body 5 b. In order to meet the construction requirements of a construction site and ensure good maneuvering flexibility, the movably spliced vehicle body 5 is designed into a fixed half vehicle body 5a and a movable half vehicle body 5b, as can be seen from fig. 5, in the state that the fixed half vehicle body 5a and the movable half vehicle body 5b are spliced, the steel casing 2 is tightly surrounded, the state is ready for drilling work, and once the drill bit 4 is lifted out of the steel casing 2, the drill bit can be separated after contacting a passive rotating stripper.
As shown in fig. 7, after the separated soil falls on the movably spliced vehicle body 5, the soil is divided in the directions of four arrows in fig. 7, and after the drilled soil is completely separated, the divided soil is pushed again in the directions of the arrows by the shielding pushing assembly, so that the soil is sufficiently far away from the steel casing 2. And advancing the subassembly and outwards opening in order to expose 2a top mouth of pipe open the back sheltering from, drill bit 4 then can reentrant the steel protects a section of thick bamboo 2 in driling, the continuity of drilling operation has been guaranteed, needn't move the drill bit away and remove to the open space region from steel protects a position like traditional technique again, thereby the noise problem has been solved, also can improve the efficiency of drilling simultaneously, only need drill bit 4 simple upwards promote and do not rotate and can realize boring the soil separation, the operation of separation soil has greatly been simplified.
