Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drilling machinery, in particular to a rotary drilling rig soil-taking device. Background Art
[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] Rotary drilling rigs are widely used in pile foundation construction due to their wide applicability, high-quality boreholes, and high efficiency. However, during soil removal, the drill bit mechanically removes soil and rock debris from the ground, which is then transported to the surface by the spiral blades of the drill pipe. The drill bit then reciprocates, relying on inertia to remove the debris and rock. This is accompanied by a high level of noise. However, the drill bit is prone to clay soil, which easily sticks to the drill bit, making clay removal inefficient. Therefore, a rotary drilling rig soil removal device is urgently needed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of the embodiment of the utility model is to provide a rotary drilling rig soil-collecting equipment, which at least solves the problem that when the equipment is rotary drilling to clean the soil, soil and stone debris adhere to or even get stuck on the spiral blades, requiring repeated drilling and reducing the efficiency of cleaning clay.
[0005] In order to achieve the above objectives, the present invention provides the following technical solutions:
[0006] A rotary drilling rig soil excavation device, comprising:
[0007] A soil cleaner and a soil box, wherein the soil box is a box body and the soil cleaner is fixed on the bottom surface of the soil box;
[0008] The soil cleaner includes an auger, which includes a drill bit and a drill rod. The free end of the drill bit is provided with a scraper, and the other end of the drill bit is fixedly connected to the drill rod. The drill rod includes a screw rod, and the screw rod is provided with a spiral blade.
[0009] High-pressure air holes are provided on the drill bit and the screw rod, and high-pressure air pipelines are provided in the drill bit and the screw rod. One end of the high-pressure air pipeline is connected to the high-pressure air hole, and the other end is connected to the high-pressure air source.
[0010] After the rotary drilling rig lifts the drill bit to the ground, it moves the drill bit to above the soil cleaner, and inserts the drill bit of the soil cleaner. The drill bit of the rotary drilling rig rotates, and the scraper breaks the soil and stone debris attached to the drill bit of the rotary drilling rig. The high-pressure air hole releases high-pressure air, and the air flow impact breaks the soil and stone debris adhered to the drill bit of the rotary drilling rig. The broken soil and stone debris are cleared out with the spiral blades. At the same time, the high-pressure air released by the high-pressure air hole can also remove the soil and stone debris adhered to the spiral blades of the screw. The soil cleaner does not need to perform the drill-throwing action.
[0011] In some embodiments, a plurality of high-pressure air holes are provided on both the drill bit and the screw, and the high-pressure air holes are evenly arranged on the drill bit.
[0012] In some embodiments, the auger is a steel auger, and the screw and the spiral blades are integrally arranged.
[0013] In some embodiments, the soil cleaner is fixed at a central position on the bottom surface of the soil box.
[0014] In some embodiments, the soil box is a box with an open top, and the drill bit of the rotary drilling rig enters from above the soil box and approaches the soil cleaner.
[0015] In some embodiments, a sound barrier is further included. The height of the sound barrier is greater than the height of the soil box and the sound barrier is sleeved on the outside of the soil cleaner.
[0016] In some embodiments, the noise barrier includes three connected rectangular structures, wherein two rectangular structures are disposed on one side of another rectangular structure, and both rectangular structures are connected to parallel sides of another rectangular structure.
[0017] In some embodiments, the height of the noise barrier is 0.5 meters higher than the height of the earth box.
[0018] In some embodiments, the sound barrier includes a honeycomb layer, a sound-absorbing cotton layer, and a color-coated steel plate layer, which can effectively absorb and isolate the noise generated by the soil cleaner.
[0019] In some embodiments, the spiral blades on the screw are continuously arranged.
[0020] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
[0021] 1. The utility model uses the coordinated arrangement of the drill bit, the drill rod and the high-pressure air hole to make the rotary drill pass through the soil cleaner, and uses the high-pressure air combined with the mechanical cutting action of the scraper to remove the soil and stone debris adhered to the drill bit of the rotary drill rig. There is no need to swing the drill, which prevents the ultra-high noise generated by the swing drill, reduces the noise of the equipment, and overcomes the problems of low efficiency and high noise caused by the traditional rotary drill when removing the adhered soil and stone debris, which relies entirely on the swing drill to clean the soil.
[0022] 2. The utility model is provided with a soil box and a sound insulation barrier to refract and absorb the noise generated by the rotation of the drill bit of the rotary drilling rig, thereby further reducing the impact of the noise generated by the rotation of the drill bit of the rotary drilling rig.
[0023] 3. The setting of the soil cleaner of the utility model solves the problem of difficulty in removing soil and stone debris adhering to the drill bit of the rotary drilling rig. The soil cleaner assists in unloading the soil, and the rotary drilling rig does not need to repeatedly throw the drill, thereby improving the soil unloading efficiency of the rotary drilling rig.

[0031] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0032] As introduced in the background technology, in the prior art, when a rotary drill is used to clean soil at the end of drilling, soil and stone debris tend to adhere to the drill bit of the rotary drill, and the drill bit needs to be repeatedly thrown off the drill. However, this operation is inefficient in cleaning clay and is prone to noise. In order to solve the above technical problems, the utility model proposes a rotary drill rig soil-collecting equipment.
[0033] like Figure 1 、 2As shown, one or more embodiments of the present invention record a rotary drilling rig soil-taking equipment, including: a soil cleaner 2 and a soil box 4, the soil box 4 is a box structure, and the soil cleaner 2 is fixed on the bottom surface of the soil box 4; the soil cleaner 2 includes an auger 5, the auger 5 includes a drill bit 6 and a drill rod 7, the drill bit 6 and the drill rod 7 are fixedly connected, and the drill rod 7 is fixed to the bottom surface of the soil box 4; the free end of the drill bit 6 is arranged upward and is provided with a scraper 11, and the fixed end of the drill bit 6 is fixedly connected to the drill rod 7; the drill rod 7 includes a screw 8 and a spiral blade 9, and the screw 8 is provided with a spiral blade 9; the drill bit 6 and the screw 8 are both provided with a high-pressure air hole 10, and the drill bit 6 and the screw 8 are both provided with a high-pressure air pipeline 14, one end of the high-pressure air pipeline 14 is connected to the high-pressure air hole 10, and the other end is connected to the high-pressure air source 13. The rotary drilling rig moves the drill bit to just above the soil cleaner 2, throws the drill and inserts it downward into the drill bit 6 of the soil cleaner 2, and continues to rotate, so that the scraper 11 rotates relatively to break the soil and stone debris attached to the rotary drilling bit. The high-pressure air hole 10 releases high-pressure airflow to impact the soil and stone debris adhered to the rotary drilling bit, and the broken soil and stone debris are cleared out with the spiral blade 9.
[0034] like Figure 3 As shown, in an optional embodiment, the drill bit 6 is provided with multiple high-pressure air holes 10, which are evenly distributed on the drill bit 6. The screw 8 is also provided with multiple high-pressure air holes 10, which are arranged in a matrix. A high-pressure air source 13 is connected to a high-pressure air pipeline 14 via an air pipe 15, and the high-pressure air pipeline 14 is in communication with the high-pressure air holes 10.
[0035] The high pressure gas source 13 is released from the high pressure gas hole 10 through the high pressure gas pipeline. The high pressure gas pipeline is provided with a valve to control the release of the high pressure gas. The pressure of the high pressure gas source 13 is conventionally set in the art to be able to break up the adhered soil debris.
[0036] In an optional embodiment, the auger 5 is a steel auger 5, and the screw 8 and the spiral blades 9 are integrally arranged. Preferably, the drill bit 6, the screw 8 and the spiral blades 9 are all integral structures, and the spiral blades 9 on the screw 8 are continuously arranged.
[0037] like Figure 2 As shown, in an optional embodiment, the soil box 4 is a box structure with an open top surface, and the soil cleaner 2 is fixed at the center of the bottom surface of the soil box 4. The top surface opening is larger than the outer diameter of the rotary drill bit, so that the rotary drill bit can freely enter the box body from above the soil box 4.
[0038] In an optional embodiment, a sound barrier 3 is provided outside the soil box 4. The sound barrier 3 is a frame-shaped structure with a notch on one side, which is mounted on the side of the soil cleaner 2 and includes three rectangular structures. The three rectangular structures have equal heights and are higher than the soil box 4.
[0039] In an optional embodiment, the sound barrier 3 includes three connected rectangular structures, two rectangular structures of the same shape and size are arranged opposite and in parallel, one side of the above rectangular structure is fixedly connected to the parallel opposite side of the other rectangular structure, and the two identical rectangular structures are arranged perpendicular to the other rectangular structure.
[0040] In an optional embodiment, the height of the noise barrier 3 is 0.5 meters higher than the height of the earth box 4.
[0041] The provision of the sound barrier 3 allows the sound generated during soil clearing to be reflected and absorbed within the sound barrier 3, thereby reducing noise pollution.
[0042] like Figure 4 As shown, in an optional embodiment, the sound barrier 3 includes a multi-layer structure including a honeycomb layer 31 , a sound-absorbing cotton layer 32 and a color steel plate layer 33 , which can effectively absorb and isolate the noise generated by the soil cleaner 2 .
[0043] During operation, the sound barrier 3 is installed outside the soil box 4, between the soil box 4 and the noise-sensitive point. The rotary drilling rig moves the drill bit into the soil box, to the position directly above the soil cleaner, swings the drill bit and inserts it downward into the soil cleaner's drill bit 6. The rotary drilling rig continues to rotate the drill bit. In the soil extraction equipment, the soil cleaner's drill bit 6 rotates relative to the rotary drilling rig's drill bit. The scraper 11 on the top of the soil cleaner's drill bit 6 mechanically cuts the soil and stone debris, breaking it up. The soil and stone debris are then transported downward along the gaps between adjacent spiral blades 9 of the screw 8, achieving soil extraction and cleaning. The high-pressure air source 13 intermittently releases high-pressure air through the high-pressure air hole 10 via an air valve, impacting the soil debris stuck in the rotary drilling rig drill bit and the clay stuck between the spiral blades 9, causing the stuck clay to break and fall off. The broken soil and stone debris are then cleared out with the spiral blades 9.
[0044] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
