[0019] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0020] Reference Figure 1 and Figure 5The utility model discloses a device for cleaning backfill soil in a lattice column. Traditional circular face drill bits can only drill circular contour holes, while the inside of a lattice column is a square contour space, so traditional circular drill bits are not suitable for cleaning backfill soil in a lattice column. Unlike traditional drill bits, the Lelo triangle drill bit can drill square contour holes. According to the principle that "the face formed by the eccentric rotation of the Lelo triangle is a square", the present invention has developed a new device for cleaning backfill soil in a lattice column. The device consists of two parts, the first part is a soil crushing device, and the second part is a jacking mechanism. One side of the Lelo triangle plate is covered with soil cutting pins 1. The Lelo triangle plate rotates to crush the soil while jacking upward, thereby achieving the purpose of mechanized soil excavation in the lattice column.

[0021] The specific composition and functions of the device are described as follows:

[0022] The soil crushing device is mainly composed of accessories such as a Lelo triangle drill bit, a square stopper 5, an eccentric transmission shaft 4, a motor 7, and a battery 8. The Lelo triangle drill bit is composed of two Lelo triangle thin plates plus a pin 1. The lower Lelo triangle plate 3 is slightly smaller than the upper Lelo triangle plate 2, and a dovetail groove 19 is left to dock with the eccentric transmission shaft 4.

[0023] The inner contour of the square stopper 5 is the same width as the contour of the lower Relox triangular plate 3, so that the Relox triangular drill bit can be just embedded in the stopper, and the stopper is fixed to the motor 7 through four foot supports 6.

[0024] The eccentric transmission shaft is in the shape of a flat cylinder, with mutually perpendicular tenons 20 at the upper and lower ends. The tenons 20 are embedded in the dovetail groove 19 and can slide along the dovetail groove. The upper and lower ends of the transmission shaft are respectively connected to the Lero triangle drill bit and the motor 7. Under the joint action of the square limiter and the eccentric transmission shaft, the motor can drive the Lero triangle drill bit to rotate eccentrically. At this time, the formed palm face is a square with slightly curved corners, which can complete the soil crushing work in the lattice column 17.

[0025] The motor is fixed on a base 9 and is equipped with a detachable rechargeable battery 8.

[0026] The lifting mechanism is mainly composed of a lifting chain 12, a chain storage box 13, a gear set, etc. The chain is driven to lift upward by the rotation of the gears. The lifting chain 12 has a mutual bite effect. After the bite, the cross-section is rectangular, which is stable and reliable and will not tip over to one side.

[0027] The lifting mechanism and the soil crushing device are connected and fixed via a base 9 and a connector 10 .

[0028] Specific implementation steps:

[0029] Step 1: Construction of the first support beam and earth excavation;

[0030] Step 2: After the excavation reaches the elevation of the next support beam, the backfill soil of the bottom grid of the lattice column is manually cleaned to reserve space for mechanical installation.

[0031] Step 3: Place the soil crushing device sideways into the lattice column through the hole, and then lay it flat.

[0032] Step 4: Insert the lifting mechanism under the soil crushing device, and connect and fix the soil crushing device and the lifting mechanism through the base.

[0033] Step 5: The soil cutting device is powered on and the Lelo triangular drill bit rotates to break up the soil.

[0034] Step 6: While the soil crushing device is running, the worker turns the crank to drive gear No. 1 14 to rotate, gear No. 1 14 drives gear No. 2 15, gear No. 2 15 drives gear No. 3 16, and gear No. 3 16 drives the chain to lift upward.

[0035] Step 7: Clean the fallen debris out of the lattice column range and complete the backfill soil cleaning work.

[0036] Step 8: Disassemble the machine and move the machine to the next lattice column.

[0037] As above, although the utility model has been shown and described with reference to a specific preferred embodiment, it should not be interpreted as limiting the utility model itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the utility model defined in the attached claims.
