AI Technical Summary
Existing square mixing drills are inefficient when drilling and are difficult to remove the drilled soil, resulting in a reduced drilling efficiency.
A square mixing drill rig was designed, using a motor to drive the gears and the tooth holes to mesh. Through the limit of the Lelo triangle limit block, the Lelo triangle drill bit rotates for a certain trajectory to form a square hole. At the same time, the circular hole drill bit is used to dig the circular hole first. The soil is collected in the shield, the hoist drives the lifting block to lift the drilling device, the motor reverses and pours it out, and then scrapes out the square holes with the Lelo triangle drill bit.
It improves drilling efficiency, which is more efficient than drilling square holes directly with a Lelo triangle drill bit, and simplifies the soil removal process.

Abstract
Description
Technical Field
[0001] The utility model relates to the drilling rig area, and in particular to a square mixing drilling rig. Background Art
[0002] Drilling machines refer to the use of tools that are harder and sharper than the target object to be used to rotate cutting or rotary extrusion. Pile holes are often required when driving piles in the construction industry.
[0003] Existing square mixing drills all use Leroy triangular drill bits to drill square holes directly. However, when the Leroy triangular drill bit drills a square hole, it needs to swing continuously, which will result in lower drilling efficiency than a drill bit for drilling a circular hole. It is also not easy to remove the drilled soil, and the knife drilling efficiency is reduced. Utility Model Content
[0004] The purpose of the utility model is to solve the disadvantages present in the prior art and propose a square mixing drill rig.

[0006] As a further description of the above technical solution:
[0007] The drilling device includes a first fixed plate, and the first fixed plate is fixedly connected to the first rotating shaft, the lower end of the first fixed plate is fixedly connected to three groups of connecting rods, the lower ends of the connecting rods are fixedly connected to a square limit frame, the lower end of the square limit frame is fixedly connected to a second fixed plate, the lower end of the first fixed plate is fixedly connected to a motor, a motor shaft is extended from the lower end of the motor, the lower end of the motor shaft is fixedly connected to the second rotating shaft, the cylindrical outer surface of the second rotating shaft is fixedly connected to a gear, a Lelo triangular limit block is arranged in the square limit frame, a tooth hole is arranged on the Lelo triangular limit block, and the tooth hole is meshed with the gear, and the Lelo triangular limit block is clamped with the second fixed plate, and the lower end of the Lelo triangular limit block is fixedly connected to a Lelo triangular drill bit.
[0008] As a further description of the above technical solution:
[0009] A guard is fixedly connected to the lower end of the second rotating shaft, and a circular hole drill bit is fixedly connected to the lower end of the shield.
[0010] As a further description of the above technical solution:
[0011] The lower end of the main bracket is fixedly connected to multiple groups of lifting support seats, the upper end of the main bracket is fixedly connected to an operating table, the lower end of the main bracket is provided with a walking frame, the upper end of the main bracket is fixedly connected to a winch, and one end of the winch is fixedly connected to the lifting block through a steel wire.
[0012] The utility model has the following beneficial effects:
[0013] 1. The utility model is provided with a motor, which can drive the gear to rotate through the second rotating shaft, thereby driving the Lelo triangle limit block to rotate through the meshing of the gear and the tooth hole, and the square limit frame limits the Lelo triangle limit block, so that the Lelo triangle limit block drives the Lelo triangle drill bit to rotate in a certain trajectory, thereby forming a square hole. At the same time, the second rotating shaft will also drive the shield to rotate, so that the round hole drill bit will first dig a round hole and store the soil in the shield. The winch drives the lifting block to rise through the steel wire, thereby bringing out the drilling device through the first rotating shaft, and the motor reverses to pour out the soil. The device first uses the round hole drill bit to drill a round hole, and then uses the Lelo triangle drill bit to scrape out a square hole. Compared with directly using the Lelo triangle drill bit to directly drill a square hole, it can have higher efficiency (the Lelo triangle drill bit needs to swing continuously when drilling a square hole, which will result in lower drilling efficiency than the drill bit for drilling a round hole, and it is not easy to remove the drilled soil).
