Problems solved by technology
[0004] The purpose of the present invention is to provide a hydraulic square pile drill bit to solve the problem that the existing square pile drill bit proposed in the above-mentioned background technology is difficult to realize the independent hydraulic system to drive the excavation wheel to rotate to realize cutting and piling, and the use safety still needs to be improved. And the energy consumption is relatively large, and the problem of great dependence on the outside world

Embodiment
[0023] see Figure 1-8 , the present invention provides a kind of technical scheme: hydraulic square pile drill bit, comprises box body 1, and the upper side wall of box body 1 is longitudinally fixedly provided with connecting square head 2, and connecting square head 2 is connected with rotary drilling rig operation square head, like this In this way, the operation, installation and fixation of the entire square pile drill bit is realized. The box body 1 is the skeleton of the entire square pile drill bit. The four corners of the upper side wall of the box body 1 are fixedly equipped with anti-rotation roller mounting supports 3, and two adjacent anti-rotation rollers are installed. An anti-rotation roller 4 is arranged to rotate between the roller installation supports 3, and it is distributed according to the four walls of the outline of the box body 1, and its outer diameter profile is slightly larger than the box body 1, so that the roller shaft can rotate independently a...

The invention belongs to the technical field of square pile drill bits, and particularly relates to a hydraulic type square pile drill bit which comprises a box body, a connecting square head is longitudinally and fixedly arranged on the upper side wall of the box body, anti-rotation roller mounting supports are fixedly arranged at the four corners of the upper side wall of the box body, and an anti-rotation roller is rotationally arranged between every two adjacent anti-rotation roller mounting supports; box body reinforcing ribs which are evenly distributed are fixedly arranged on the side wall of the connecting square head, an independent hydraulic system is used for driving the excavating wheel to rotate so as to achieve cutting and piling, mechanical rotation power does not need to be taken from the rotary drilling rig, and input high-pressure oil needed by the hydraulic system is obtained by shunting hydraulic oil of the hydraulic system of the rotary drilling rig. The connecting square head of the rotary drilling rig only plays a role in mounting and supporting the whole square pile drill bit, so that the whole equipment is firmer in the aspect of safety, lower in energy consumption, more environment-friendly, more independent in system and smaller in external dependence, and the requirement for the operation environment of the equipment is looser.
Description
technical field [0001] The invention relates to the technical field of square pile drill bits, in particular to a hydraulic square pile drill bit. Background technique [0002] At present, square piles are gradually being used in practical projects in my country. Compared with circular piles, square piles greatly increase the lateral friction area of piles under the same cross-sectional area, that is, the same amount of materials, and improve the lateral friction area of piles. The bearing capacity of the pile is greatly improved. The rotary drilling rig is a kind of pile construction equipment used for hole-forming operations. With the vigorous development of domestic foundation engineering in recent years, the rotary drilling rig has been widely used. [0003] The currently used square pile drill bit is difficult to achieve independent hydraulic system to drive the excavation wheel to rotate to realize cutting and piling. The safety of use needs to be improved, and the ...
