Specific embodiment
Carry out the embodiment that the present invention will be described in detail below in conjunction with accompanying drawings and embodiments, how the present invention is applied whereby Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
Specific embodiments of the present invention are as shown in Figures 1 to 5, shown in Fig. 1-5, a kind of antiswing device for drilling bucket, and packet Include drilling rod 1, the square toes 2 being fixedly connected with 1 lower end of drilling rod, the drilling bucket 3 positioned at 2 lower section of square toes;It further include being fixed on drilling bucket 3 The brill connector 4 of end face, the position-arresting disk 5 and round nut 6 being fixed on square toes 2;Boring connector 4 includes internal for hollow side Shape cone cylinder 41, welding are set to the ring flange 42 of rectangular 41 top end opening outer rim of cone cylinder;2 lower end of square toes extend into rectangular cone cylinder 41 Inside, square toes 2 are fixedly connected by pin shaft 7 with rectangular cone cylinder 41;Ring flange 42 and protruding from is set on the end face of rectangular cone cylinder 41 Have the limiting through hole 421 of circumferentially array distribution, round nut 6 is embedded in limiting through hole 421, and with 421 interference of limiting through hole Cooperation;Position-arresting disk 5 is equipped with counter sink 51 corresponding with limiting through hole 421, and 6 internal screw thread of round nut is connected with to be bored for adjusting Bolt 8 of the bucket 3 in axial angulation;Projection with a narrow upper and lower width ladder of rectangular 41 inner surface of cone cylinder on axial cross section Shape;The floor space of the inner surface of rectangular cone cylinder 41 is greater than the floor space of 2 outer surface of square toes.
The one side welding of the ring flange 42 is equipped with support plate 9, the support plate 9 and 42 flush of ring flange, In the support plate 9 and one end end far from the rectangular cone cylinder 41 is equipped with through-hole.The effect of through-hole is worn for push rod 12 It crosses, wherein the bottom end of push rod 12 passes through the engaging angle of 3 lower plate of link mechanism drive control drilling bucket, to control discharging.
Set that there are two be mutually perpendicular to but disjoint pin shaft hole 21 on the square toes 2;Welding is set in the rectangular cone cylinder 41 There is the positioning disk 10 of setting corresponding with the pin shaft hole 21;The pin shaft 7 is fixed on the positioning disk 10 and the pin shaft In hole 21, and the square toes 2 are fixedly connected with the rectangular cone cylinder 41.Spatially vertical interlaced is arranged pin shaft 7, therefore The constraint positioning of square shaped cone cylinder 41 is realized at the different height of square toes 2, and then drilling bucket 3 has been further prevented to produce at work Raw biggish beat, improves the job stability of drilling bucket 3.
Stiffening plate 11 there are four setting, the stiffening plate are welded between 3 top of bottom and the drilling bucket of the ring flange 42 11 are welded to connect with the lateral wall of the rectangular cone cylinder 41.The normal of drilling bucket 3 is not influenced while increasing by 42 intensity of ring flange Loading and unloading.
It bores in the counter sink 51 on the head of the bolt 8.Wherein counter sink 51 is for installing bolt 8, the spiral shell of bolt 8 Club head abuts on the inner wall of the large aperture of counter sink 51, so that preventing drilling bucket from swinging.
It is above to implement, specifically, by ring flange 42 and protruding from and being equipped with circumferentially on the end face of rectangular cone cylinder 41 The limiting through hole 421 of array distribution, round nut 6 are embedded in limiting through hole 421, and are interference fitted with limiting through hole 421, limit Through-hole 421 and round nut 6 are interference fitted, and avoid the tapping at the limiting through hole 421 of ring flange 42, and it is difficult both to reduce manufacture Degree, and saved cost;Projection of rectangular 41 inner surface of cone cylinder on axial cross section is with a narrow upper and lower width trapezoidal;Rectangular cone cylinder 41 The floor space of inner surface be greater than the floor space of 2 outer surface of square toes, and 2 lower end of square toes is extend into inside rectangular cone cylinder 41, side First 2 are fixedly connected by pin shaft 7 with rectangular cone cylinder 41, are not only convenient for the positioning assembly of 2 square shaped cone cylinder 41 of square toes, are improved replacement The efficiency of drilling bucket 3, moreover it is possible to guarantee the transmitting of the work torque of drilling rod 1;Position-arresting disk 5 is equipped with corresponding with limiting through hole 421 heavy Head bore 51,6 internal screw thread of round nut are connected with for adjusting drilling bucket 3 in the bolt 8 of axial angulation, and the screw head of bolt 8 is bored Enter counter sink 51, by adjusting the pretightning force of bolt 8, drilling bucket 3 and axial angulation can either be finely tuned, moreover it is possible in drilling It prevents drilling bucket 3 from swinging, improves the axially position precision and ability to work of drilling bucket 3.
Concrete operating principle is, before rotary digging machine operation, by 41 basis of rectangular cone cylinder of the square toes 2 of drilling rod 1 and brill connector 4 The position of pin shaft 7 and pin shaft hole 21 is assembled, and is inserted into pin shaft 7;It, will be on round nut 6 and ring flange 42 in Spiral digging machine drilling Limiting through hole 421 is assembled, then bolt 8 is matched with round nut and merges the counter sink 51 bored on position-arresting disk 5, adjusts each bolt 8 Pretightning force, angulation between control flange disk 42 and position-arresting disk 5 guarantees drilling bucket 3 to limit the swing of drilling bucket 3 Axially position precision.
The beneficial effects of the present invention are:
1, in a kind of antiswing device for drilling bucket of the present invention, limiting through hole and round nut on ring flange are interference fitted, The tapping at limiting through hole is avoided, not only reduces manufacture difficulty, but also saved cost;Bolt matches to merge with round nut bores into limit Counter sink on the disk of position can not only finely tune drilling bucket and axial angulation, moreover it is possible to bore by adjusting the pretightning force of bolt It prevents drilling bucket from swinging when hole, improves the axially position precision and ability to work of drilling bucket.
2, in a kind of antiswing device for drilling bucket of the present invention, projection of the rectangular cone cylinder inner surface on axial cross section is presented It is narrow trapezoidal under width, and the floor space of rectangular cone cylinder inner surface is greater than the floor space of the square toes outer surface, is not only convenient for square toes The positioning of square shaped cone cylinder is assembled, and the efficiency of replacement drilling bucket is improved, moreover it is possible to guarantee the transmitting of drilling rod work torque.
3, the present invention can not only prevent drilling bucket from swinging in drilling, improve the ability to work of drilling bucket, moreover it is possible to increase structure The normal loading and unloading of drilling bucket is not influenced while design strength, and entirely designs and produces that simple, practicability is good, is had very strong Promotional value.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This Invention is not only limited to above embodiments, and specific structure is allowed to vary.All protection models in independent claims of the present invention Interior made various change is enclosed to all fall in the scope of protection of the present invention.
