Background technique

At present, the cement-soil pile forming machine all drives the drill bit to rotate into a round pile by the drill rod.

Contents of the invention

The present invention makes up for the above shortcomings and provides an octagonal cement-soil pile forming machine.

The present invention is achieved through the following technical solutions:

An octagonal cement-soil pile forming machine, the lower end of the long rod is connected to fix the upper end of the driver, the lower end of the driver is fixed to the upper end of the transfer case, the lower part of the transfer case is driven in the middle of the upper end of the drill rod, and the lower end of the drill rod is provided with a drill bit; the upper part of the drill rod The first square tube is covered, the upper end of the first square tube is fixed to the lower end of the transfer case, the lower part of the first square tube is covered with the second square tube, and the second square tube is fixed to the octagonal frame through two left and right horizontal bars. center; the left end of the transfer case is provided with a first crankshaft, the first crankshaft is hinged to the upper end of the first linkage arm, the lower end of the first linkage arm is hinged to the left end of the octagonal frame, and the right end of the transfer case is provided with a second crankshaft, which is hinged to the second The upper end of the linkage arm and the lower end of the second linkage arm are hinged to the right end of the octagonal frame; the lower part of the octagonal frame is evenly distributed with a plurality of longitudinal teeth, and each inner corner of the octagonal frame is respectively provided with a plurality of transverse teeth horizontally, and the plurality of transverse teeth connect the drill bit The area outside and within the octagonal frame is covered.

The present invention has following characteristics:

The octagonal frame of the present invention uses the first square tube as a slide rail to move up and down. During the up-and-down movement of the octagonal frame, a plurality of longitudinal teeth at the bottom of the octagonal frame cut the soil, and a plurality of transverse teeth at the inner corners of the octagonal frame cut the soil. The soil outside the drill bit and within the octagonal frame is mixed with the cement slurry to form an octagonal prism cement-soil pile.

Description of drawings

Below in conjunction with accompanying drawing, the present invention will be further described:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the A-A view of Fig. 1;

In the figure: 1. extension rod, 2. driving machine, 3. transfer case, 4. first crankshaft, 5. second crankshaft, 6. first linkage arm, 7. second linkage arm, 8. first Square pipe, 9, the second square pipe, 10, octagonal frame, 11, longitudinal teeth, 12, drill rod, 13, drill bit, 14, cross bar, 15, transverse teeth.

Detailed ways

Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment connects the lower end of long rod 1 and fixes the upper end of driver 2, and the lower end of driver fixes the upper end of transfer case 3, and the middle of the lower part of transfer case is transmitted to the upper end of drill rod 12, and the drill rod The lower end is provided with a drill bit 13; the upper part of the drill rod is covered with a first square pipe 8, the upper end of the first square pipe is fixed on the lower end casing of the transfer case, the lower part of the first square pipe is covered with a second square pipe 9, and the second square pipe passes through the left and right Two cross bars 14 are fixed on the center of the polygonal frame 10; the left end of the transfer case is provided with a first crankshaft 4, the first crankshaft is hinged to the upper end of the first linkage arm 6, the lower end of the first linkage arm is hinged to the left end of the polygonal frame, and the right end of the transfer case is arranged There is a second crankshaft 5, the second crankshaft is hinged to the upper end of the second linkage arm 7, and the lower end of the second linkage arm is hinged to the right end of the octagonal frame; the lower part of the octagonal frame is evenly distributed with a plurality of longitudinal teeth, and each inner corner of the octagonal frame is horizontally A plurality of transverse teeth 15 are provided, and the plurality of transverse teeth cover the area outside the drill bit and inside the octagonal frame.

The drill rod rotates in the first square pipe.

The second square tube slides on the first square tube.

When the present invention works, the driver is driven by the transfer case, the drill rod drives the drill bit to rotate, the slurry supply device supplies cement slurry to the drill bit, and the soil is cut and the cement slurry is stirred during the drill bit rotation; the transfer case simultaneously drives the first drill bit on the left. The crankshaft rotates, and at the same time drives the second crankshaft on the right to rotate. During the rotation, the first crankshaft and the second crankshaft drive the octagonal frame to move up and down through the first linkage arm and the second linkage arm with the first square tube as the slide rail. During the up and down movement of the octagonal frame, the multiple longitudinal teeth at the lower part of the octagonal frame cut the soil, and the multiple horizontal teeth at the inner corners of the octagonal frame mix the soil with the cement slurry outside the drill bit and within the octagonal frame to form eight Prismatic soil cement pile.
