The rotating platform is arranged on the chassis body and can rotate relative to the chassis body. The power system is fixedly arranged on the rotating platform and provides power for the whole. The drilling mechanism is arranged at one end of the rotating platform and also includes a leg mechanism. The end of the leg mechanism is provided with a wheel. By arranging the rotating platform on the chassis body, wireless relative rotation can be achieved between the vehicle body and the chassis body when turning, thereby making the overall flexibility stronger and the road condition adaptability stronger.

[0005] The leg support mechanism includes a thigh support, a first adjustment component, a second adjustment component and a shank support. One end of the thigh support is rotatably connected to the chassis body. The first adjustment component is used to adjust the angle between the thigh support and the axis of the vehicle body. The shank support is rotatably connected to the other end of the thigh support. The wheel is arranged at the end of the shank support. The second adjustment component can adjust the angle between the shank support and the thigh support, thereby ensuring that the axis of the wheel always remains parallel to the travel direction of the vehicle body. By adjusting the angle between the thigh support and the chassis body by the first adjustment component, the interval between the two wheels on the same side can be adjusted to adapt to various road conditions. Secondly, by setting the second adjustment component, the angle between the tire and the travel direction can be adjusted, thereby ensuring that the tire plane is consistent with the travel direction, preventing tire wear and extending the tire service life.

[0006] The first adjusting component includes a first hydraulic cylinder, one end of which is fixed to the chassis body, and the other end is connected to the support leg. Controlling the extension and retraction of the first hydraulic cylinder can change the angle between the support leg and the direction of travel. By adjusting the angle between the support leg and the chassis body, the vehicle can adapt to narrow roads and easily avoid obstacles when traveling on narrow roads. In addition, when traveling on bumpy sections, the first adjusting component can be adjusted to ensure that the support leg on the same side remains in an open state or other state, thereby making it easy to cross or avoid potholes and improve overall passability.

[0007] The calf support is rotatably connected to the end of the thigh support, and the second adjustment component includes a second hydraulic cylinder, one end of the second hydraulic cylinder is arranged at the end of the thigh support, and the other end is connected to the calf support. The extension and contraction of the second hydraulic cylinder can change the angle between the calf support and the thigh support, and the angle between the calf support and the traveling direction of the chassis body is controlled by controlling the extension and contraction of the second hydraulic cylinder, thereby controlling the angle between the plane where the wheel is located and the traveling direction.

[0026] See also Figures 1 to 3 , including a chassis body, a rotating platform, a power system and a drilling mechanism. The rotating platform is arranged on the chassis body and can rotate relative to the chassis body. The power system is fixedly arranged on the rotating platform and provides power for the whole. The drilling mechanism is arranged at one end of the rotating platform. It also includes a leg mechanism, and a wheel is arranged at the end of the leg mechanism. By arranging the rotating platform on the chassis body, wireless relative rotation can be achieved between the vehicle body and the chassis body when turning, thereby making the overall flexibility stronger and the road condition adaptability stronger.

[0027] It can be understood that the power system is fixed on the rotating platform of the chassis body of this design, and the remaining drilling mechanisms and digging arms are optional. The purpose is to enable the functional modules to be flexibly changed and detachable, so they can be selected according to actual needs when needed.

[0028] Furthermore, the leg support mechanism includes a thigh support, a first adjustment component, a second adjustment component and a shank support. One end of the thigh support is rotatably connected to the chassis body. The first adjustment component is used to adjust the angle between the thigh support and the axis of the vehicle body. The shank support is rotatably connected to the other end of the thigh support. The wheel is arranged at the end of the shank support. The second adjustment component can adjust the angle between the shank support and the thigh support, thereby ensuring that the axis of the wheel always remains parallel to the traveling direction of the vehicle body. By adjusting the angle between the thigh support and the chassis body by the first adjustment component, the interval between the two wheels on the same side can be adjusted to adapt to various road conditions. Secondly, by setting the second adjustment component, the angle between the tire and the traveling direction can be adjusted, thereby ensuring that the tire plane is consistent with the traveling direction, preventing tire wear and extending tire service life.

[0029] Furthermore, the first adjusting component includes a first hydraulic cylinder, one end of which is fixed to the chassis body, and the other end is connected to the support leg. Controlling the extension and retraction of the first hydraulic cylinder can change the angle between the support leg and the direction of travel. By adjusting the angle between the support leg and the chassis body, the vehicle can adapt to narrow roads and easily avoid obstacles when traveling on narrow roads. In addition, when traveling on bumpy sections, the first adjusting component can be adjusted to ensure that the support leg on the same side remains in an open state or other state, thereby making it easy to cross or avoid bumpy sections and improving overall passability.

[0030] Furthermore, the calf support is rotatably connected to the end of the thigh support, and the second adjustment component includes a second hydraulic cylinder, one end of the second hydraulic cylinder is arranged at the end of the thigh support, and the other end is connected to the calf support, and the extension and contraction of the second hydraulic cylinder can change the angle between the calf support and the thigh support, and the angle between the calf support and the traveling direction of the chassis body is controlled by controlling the extension and contraction of the second hydraulic cylinder, thereby controlling the angle between the plane where the wheel is located and the traveling direction.

[0031] It can be understood that its end is rotatably connected to the chassis body and can rotate freely, and the first adjustment component is a first hydraulic cylinder, and its telescopic end is connected to the thigh support, so that when the telescopic end is extended and retracted, it can drive the thigh support to rotate relative to the chassis body, thereby controlling the degree of opening of the thigh support. Similarly, the second hydraulic cylinder is also controlled in this way.

[0032] Furthermore, the rotary platform is provided with a plurality of connection parts, and the power system and the drilling mechanism are respectively and correspondingly arranged on the plurality of connection parts.

[0033] Furthermore, the drilling mechanism includes a propulsion system and a down-the-hole drill bit, and the down-the-hole drill bit is arranged at the end of the propulsion system, and the propulsion system can push the down-the-hole drill bit to perform a down-the-hole drilling operation.

[0034] It can be understood that its propulsion system belongs to the technical content of existing equipment, and only a general description is given here. The rotating motor of its propulsion system is used to provide axial rotational force for the down-the-hole drill bit. The impactor connected to the down-the-hole drill bit can output axial impact force to the down-the-hole drill bit, thereby achieving the effect of crushing rocks.

[0035] Furthermore, the down-the-hole drill bit includes a head and a body, the head and the body are integrally formed, the head is provided with drilling teeth and crushing teeth, the crushing teeth can crush stones, and the drilling teeth can grind small pieces of stones into powder. The crushing teeth and drilling teeth work together, and can be used like an ordinary drill bit under the same geological conditions. Under different geological conditions, the independently arranged crushing teeth can increase the instantaneous pressure of the impact, and then the strong pressure can shatter the soil or stone layers of different materials, thereby preventing the pile hole from being eccentric. The crushing teeth can shatter the soil or stone layers of different materials in advance, and then the broken small stones can be ground into powder by the drilling teeth, and then the pile hole can be drilled.

[0036] It can be understood that during the drilling process, the crushing teeth on the head, while crushing, also have a guiding role for the homogeneous layer (i.e. the same geological layer conditions, such as pure soil layer or pure stone layer), by pre-drilling a pre-drilled hole through the crushing teeth, guiding the drill bit as a whole to drill in the direction of the pre-drilled hole, so that there is a tiny pre-drilled hole each time during the drilling process, guiding the drill bit to drill in the direction of this pre-drilled hole, thus ensuring the coaxiality of the drilled pile hole, preventing the center of the pile hole from being inconsistent with the upper and lower axes due to the pile hole being too deep.

[0037] Furthermore, there are several drill teeth and one crushing tooth, and the crushing tooth is arranged in the middle of the head. There are several drill teeth that are fully distributed on the surface of the head. The height of the crushing tooth is greater than the height of the drill tooth. By setting the crushing tooth with a height higher than the drill tooth, when drilling, the crushing tooth can make point contact with the hard stone to increase the pressure and improve the stone breaking efficiency. In addition, the crushing hole produced by the crushing tooth can also be used as a guide hole, thereby improving the overall coaxiality of the pile hole and preventing the hole from deviating from the axis, thereby achieving the effect of killing two birds with one stone.

[0038] Furthermore, the head is circular, the height of the crushing teeth is equal to the radius of the head, and the crushing teeth are located at the center of the head.
