Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a movable square drilling machine. Background Art

[0002] Drilling machinery refers to a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. In the construction process, before building the column base, it is usually necessary to use a square drilling machine to drill a square hole in the ground, and then pour concrete in the hole to form the column base.

[0003] According to a disclosed movable square drilling device for foundation construction (publication number: CN110513041B), the central hole-digging component and the side hole-digging component of the above-mentioned application can work simultaneously to perform square drilling, which is labor-saving and efficient. In addition, the soil drilled out during the rotary excavation process will be transported to the mud storage chamber under the left and right of the baffle for storage, reducing the workload of workers for cleaning the soil in the excavated hole in the later stage.

[0004] However, in actual use of the above-mentioned equipment, when the soil drilled out during the rotary excavation process enters the mud storage chamber for collection, most of it will accumulate at the connection between the mud storage chamber and the drill bit. As the drilling work progresses, the drilling machine will continue to vibrate slightly, and the accumulated soil and dust will slide back into the borehole, affecting the drilling progress, increasing the machine load, and affecting the service life of the machine. In view of this, we propose a movable square drilling machine. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a movable square drilling machine, comprising a frame 1, a crawler 2 is arranged on the outer side of the frame 1, and the crawler 2 can drive the frame 1 to move when it is started, so that the frame 1 can be quickly and conveniently moved to other working areas, and a square hole drilling machine 3 is arranged inside the frame 1. The square hole drilling machine 3 adopts a Lelo drill bit to directly drill a square hole, and a dredging component is arranged inside the frame 1.

[0026] The dredging assembly includes: a triangular plate 401, a square frame 403, a square air pipe 406 and an air pump 409. The triangular plate 401 is fixedly mounted on the inner bottom surface of the frame 1. The bottom surface area of ​​the triangular plate 401 is the same as the inner bottom surface area of ​​the frame 1. A through hole 402 is opened at the center of the upper surface of the triangular plate 401. The square hole drill 3 can drill downward through the through hole 402 to avoid the set triangular plate 401 hindering the work of the square hole drill 3. The soil brought into the interior of the frame 1 during the drilling process will fall to the top of the triangular plate 401, and then slide downward along the front and rear inclined surfaces of the triangular plate 401, and finally slide out of the interior of the frame 1 to avoid accumulation at the through hole 402, which causes the soil to continuously return to the drilling place during the drilling process, thereby affecting the drilling progress.

[0027] The square frame 403 is arranged above the triangular plate 401, and a support rod 404 is fixedly installed on the outer surface of the square frame 403. One end of the support rod 404 away from the square frame 403 is fixedly connected to the inner wall of the frame 1. The square frame 403 is fixedly installed inside the frame 1 through the support rod 404. The inner wall surface of the square frame 403 is provided with a chamfer 405. The square air pipe 406 is arranged above the square frame 403. The square air pipe 406 and the square frame 403 are connected by a U-shaped rod 406. 07 fixed connection, the square air pipe 406 is located just above the square frame 403, a plurality of exhaust holes are provided on the bottom surface of the square air pipe 406, a connecting pipe 408 is fixedly installed on the top of the square air pipe 406, a square shell 410 is fixedly installed inside the square air pipe 406, the square frame 403 is sleeved on the outside of the square shell 410, the air pump 409 is fixedly installed on the inner wall surface of the frame 1, and one end of the connecting pipe 408 away from the square air pipe 406 is fixedly connected to the outer air supply pipe of the air pump 409.

[0028] When the air pump 409 is started, air can be drawn into the square air pipe 406 through the connecting pipe 408. At this time, the gas will reach the square frame 403 through the exhaust hole opened at the bottom of the square air pipe 406, and then the gas will flow downward along the inclined surface of the chamfer 405. The gas passing through the chamfer 405 will hit the outside of the square shell 410, and will be refracted on the outside of the square shell 410 and flow to the outside of the through hole 402. At this time, the flowing gas will blow the soil accumulated on the outside of the through hole 402, further preventing the soil from accumulating at the through hole 402 and falling back into the drilling hole, affecting the drilling progress.

[0029] A protective shell 501 is fixedly installed on the top of the air pump 409. A filter hole 502 is provided on one side surface of the protective shell 501 near the inner center of the frame 1. The protective shell 501 is sleeved on the outer side of the air suction end at the top of the air pump 409 to protect the air suction end. The filter hole 502 can filter the gas extracted by the air pump 409 to prevent dust and impurities in the air from entering the air pump 409 and causing damage to the air pump 409.

[0030] In the utility model, when in use, when the square hole drill 3 passes downward through the through hole 402 to perform a drilling operation, as the square hole drill 3 rotates, the dust and dirt that are brought up and enter the interior of the frame 1 will fall to the top of the triangular plate 401, and then will flow toward the outside of the frame 1 along the inclined surface of the triangular plate 401, to prevent the dirt from accumulating on the outside of the through hole 402 and causing it to return to the drilling site and affect the drilling progress. At the same time, the air pump 409 can be started to draw air into the square air pipe 406, so that the bottom of the square air pipe 406 discharges gas downward, and the gas will flow to the outside of the through hole 402 after double guidance and refraction through the chamfer 405 and the outer wall of the square shell 410, blowing the dirt and dust that fall to the outside of the through hole 402, accelerating the dirt and dust to slide on the triangular plate 401, and further preventing the dirt and dust from accumulating on the outside of the through hole 402 and causing it to return to the inside of the drilling site.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
