Description

N 360 ° of automatic desilt mechanical devices of auger stem rotation

Technical field

The present invention relates to the construction foundation working equipment technical field, be applicable to the mechanical device of the automatic desludging of auger stem piling pore-forming drill.

Background technology

The mechanical device of the automatic desludging of auger stem piling pore-forming drill has at present: screw pile machine drilling rod desilter and the automatically clear mud device that is used for the long bolt piling pore-forming drill, have reasonable in design, and substituted the clear mud of conventional artificial; Speed is fast, efficient is high, and has got rid of clod and fall the potential safety hazard that injures the operator by a crashing object from eminence, but defective also clearly; Need additionaling power during desilt; Complex structure, cost is high, adorns, tears open trouble.Do not need additionaling power when realizing desilt, simple in structure, with low cost, adorn, tear open and transport simply light, rely on prior art still can not finely to solve.

Summary of the invention

The objective of the invention is: design N 360 ° of automatic desilt mechanical devices of a kind of auger stem rotation, desilt automatically, and simple in structure can effectively overcome the defective of prior art existence.

Realize that the technical scheme that the present invention taked is: this device is with the hook (hooked) bolt fixed stay by a conical funnel, and tiltedly quadrangle desilt blade and oblique quadrangle sheath are formed; At first that an end of fixed stay band hook (hooked) bolt is downward, and the other end upwards is connected on the outer wall of funnel lower end, outer wall penetrates in the funnel and is fixed on the hopper walls end of sheath band acute angle through the funnel lower end; The equal opening in sheath two ends; The plane and the auger stem parallel axes at inner port place, with the distance of drilling rod flight with the funnel lower port, sheath is consistent with the gradient of drilling rod flight with the angle of horizontal plane; The sheath facade is parallel with the tangent line of crossing auger stem outer wall incision superius; One end of desilt blade strip acute angle blade is clipped between two flights and pastes mutually with the auger stem outer wall in sheath inserts funnel, and parallel with the tangent line of crossing auger stem outer wall incision superius; The both sides of the desilt blade other end are connecting two back-moving springs respectively, and the other end of spring all is connected on the funnel outer wall.

For the ease of mounting or dismounting and desilt, conical funnel is formed by connecting through clamping plate and bolt in two half-conical tubes of symmetry, wherein has mud leakage port adjacent with sheath on a slice half-conical tube small end outer wall.

For adjusted control desilt blade; A handle hole is established in its outer end; Middle part one pin-and-hole and pin match partially, stay certain adjusting space between desilt blade upper and lower sides and sheath, and back-moving spring and funnel outer wall junction upper and lower all leave the tie point that can regulate.

Good effect of the present invention is: simple in structure, easy to operate, make easily, small investment, with low cost, safe and reliable, do not need additionaling power just can root out body refuse, and adorn, tear open, transport simply light.

The specific embodiment

The present invention is like Fig. 1, shown in 2; This device is by a conical funnel 1; Band hook (hooked) bolt 10 fixed stays 2, tiltedly quadrangle desilt blade 3 and oblique quadrangle sheath 5 are formed; Two half-conical tubes at first will forming funnel 1 symmetry are connected (like accompanying drawing 2, shown in 3) through clamping plate 14 with bolt 15, wherein establish a mud leakage port 4 (like accompanying drawing 1,2, shown in 3) on the small end outer wall of a slice half-conical tube, and an end of fixed stay 2 band hook (hooked) bolts 10 is downward; And the other end upwards is connected (like accompanying drawing 1, shown in 2) on the funnel 1 lower end outer wall; One end of sheath 5 band acute angles penetrates in the funnel 1 near the left side of funnel 1 lower end outer wall mud leakage port 4 and is fixed on (shown in accompanying drawing 2) on funnel 1 wall, the equal opening in sheath 5 two ends, the plane and auger stem 12 parallel axes at inner port place; With the distance of drilling rod flight 13 with funnel 1 lower port; Sheath 5 is consistent with the gradient of drilling rod 12 flights 13 with the angle of horizontal plane, sheath 5 facades and the tangent line parallel (like accompanying drawing 1,2, shown in 3) of crossing auger stem 12 outer wall incision superiuses, and desilt blade 3 band acute angle blades one end inserts in the funnel 1 through sheath 5; Be sandwiched between two flights 13 and paste mutually with auger stem 12 outer walls and parallel with the tangent line of crossing auger stem 12 outer wall incision superiuses; The both sides of desilt blade 3 other ends are connecting two back-moving springs 6 respectively, and the other end of back-moving spring 6 all is connected (like accompanying drawing 1, shown in 2) on funnel 1 outer wall, for adjusted control desilt blade 3; A handle hole 9 is established in its outer end; Pin-and-hole in middle part 8 matches (as shown in Figure 1) with pin 7 partially, and 5 of desilt blade 3 upper and lower sides and sheaths stay certain adjusting space, and back-moving spring 6 all leaves the tie point that can regulate with funnel 1 outer wall junction upper and lower.

Method for using of the present invention is: two half-conical jacket casings will forming circular cone tube 1 symmetry are connected with bolt 15 through clamping plate 14 outside auger stem 12, in funnel 1 lower port insertion casing 11 is suitable for reading; Hook bolt 10 on the fixed stay 2 hooks the end opening wall of casing 11 and fastening, is pulled outwardly desilt blade 3 through handle hole 9, inserts in the pin-and-holes 8 with pin 7; Desilt blade 3 band blades one end leaves drilling rod 12 flights 13, when stake machine auger stem 12 is raised, the stake machine mobile the time clod that falls receive by funnel 1, when falling auger stem 12 borings again; Hold desilt blade 3 handle holes 9, take out pin 7, aim at drilling rod 12 outer walls between two flights 13; Unclamp handle hole 9; Under the effect of back-moving spring 6, desilt blade 3 band blades one end is tightened up to be attached on auger stem 12 outer walls and carries out desilt, and mud spills from mud leakage port 4.When running into auger stem 12 flange nodes in the desilt process, desilt blade 3 can pull out blade 3; Treat that auger stem 12 flange nodes unclamp desilt blade 3 more later and carry out desilt; If when removing drilling rod 12 outer walls between the trowel 3 swords one end misalignment flight 13; In sheath 5, can adjust desilt blade 3 and the tie point of back-moving spring 6 up and down, or funnel 1 is adjusted along casing 11 circumference with funnel 1 outer wall.
