Description

Rotary drilling rig discharging auxiliary device and rotary drilling rig Technical Field The invention relates to a rotary drilling rig discharging auxiliary device and a rotary drilling rig, and belongs to the technical field of engineering machinery. Background In the construction process of the rotary drilling rig, the loading rotation is a very frequent action used in the construction operation, and the rotary drilling rig turntable mainly comprises a rotary speed reducer, a rotary support, a turntable main body, a drill mast support and the like and has the function of bearing the weight of the upper part and enabling the weight to perform the rotation motion. The rotary motion of the turntable is that the hydraulic motor is driven by the hydraulic pump to supply oil and the rotary support annular gear is driven by the pinion of the rotary speed reducer so as to enable the upper vehicle to rotate. The main purpose of the on-vehicle rotation is to unload soil after one drilling is completed, the operation efficiency of the rotary drilling rig can be greatly reduced due to frequent rotation of the soil unloading, the position of the hole cannot be accurately positioned after the soil unloading is completed, and once the on-vehicle rotation mechanism fails, the whole construction is put aside, so that serious loss of the whole engineering project is caused. Disclosure of Invention The invention aims to overcome the defects in the prior art, provides a rotary drilling rig discharging auxiliary device and a rotary drilling rig, and solves the technical problems of waste of operation time and low efficiency caused by rotary soil discharging in the drilling process of the rotary drilling rig. In order to achieve the above purpose, the invention is realized by adopting the following technical scheme: The invention provides a rotary drilling rig discharging auxiliary device which comprises a rotary drilling rig body, a rotary mechanism arranged at the bottom of the rotary drilling rig body, a mechanical arm arranged at the movable end of the rotary mechanism and a hopper arranged at the end part of the mechanical arm, wherein when the rotary drilling rig body finishes one-time rotary soil loading and lifting of a drilling tool to the ground for soil discharging, the hopper is adjusted to the position below the drilling tool for soil receiving and soil discharging through the rotary mechanism and the mechanical arm. Optionally, the swing mechanism includes box, level set up in the worm wheel at box middle part, vertically wear to locate the worm wheel axle at worm wheel middle part, set up in worm wheel both sides and cover locate the epaxial support bearing of worm wheel, set up in worm wheel one side and with worm wheel meshing worm and connect the gear motor on the worm, support bearing outer lane and the inside fixed connection of box, the worm wheel axle bottom extends to the box outside and connects the arm. The mechanical arm comprises a first telescopic arm, a supporting beam arranged at the end part of the movable end of the first telescopic arm and adjusting arms arranged at the two ends of the supporting beam, wherein each adjusting arm comprises a first supporting rod and a second supporting rod which are connected through a ball head, the end part of the first supporting rod is fixedly connected with the supporting beam, the end part of the second supporting rod is hinged with a hopper, a second telescopic arm and a third telescopic arm are respectively arranged on the upper side and the outer side of the adjusting arm, and the movable end and the fixed end of the second telescopic arm and the fixed end of the third telescopic arm are respectively hinged with the second supporting rod and the first supporting rod. Optionally, the second bracing piece downside is provided with the flexible arm of fourth, flexible arm expansion end and stiff end tip respectively with hopper and second bracing piece hinge. Optionally, the first telescopic link, the second telescopic link, the third telescopic link, the fourth telescopic link adopt pneumatic cylinder or electric putter. In a second aspect, the invention provides a rotary drilling rig comprising the above-mentioned discharge auxiliary device. Compared with the prior art, the invention has the beneficial effects that: According to the unloading auxiliary device of the rotary drilling rig and the rotary drilling rig, provided by the invention, the rotary mechanism and the mechanical arm are used for controlling the hopper to receive the material soil and finish unloading the soil, so that the rotary drilling rig is replaced to load the rotary drilling rig for rotary unloading the soil, the time waste and potential safety hazards caused by the process are solved, and the integrated design is adopted, so that the device is convenient to use and popularize.
