Abstract
The utility model discloses a columnar gear with novel structure for a cutting pick of a digger. The columnar gear comprises a tampered spherical body at the upper part, a cylinder at the middle part and a small cylinder at the lower part and is applied on the cutting pick of the digger. The columnar gear can protect the body of the cutting pick free from abrasion, enhance the welding strength, reduce the depletion of the cutting pick, prolong the service life, improve the work efficiency and reduce coal mining cost. The columnar gear is simple in structure, convenient to process and wide in application range and can be combined with the cutting pick body to from a novel cutting pick for the digger and can also be applied on geological and engineering machinery.
Description
Technical field
The utility model relates to coal industry digger field of mechanical technique, specifically is a kind of novel pick post tooth.
Background technology
Pick is the strength member on the digger, also is the consumption maximum, the part of easy damage.The technical requirements regulation of People's Republic of China's coal industry standard " colliery pick MT246-1996 ": the colliery is to be welded by the denticle and the hard alloy columnar teeth that adopt structural alloy steel with the digger pick.Hard alloy columnar teeth generally is to be the pointed cone cylindrical structure by the upper end, and its shortcoming post tooth upper end taper is too small, and the post tooth is stressed minimum when pick cut, the stressed maximum of denticle, wear and tear the fastest.Cause denticle upper end and hard alloy columnar teeth connecting portion premature wear, hard alloy columnar teeth leaks outside, and at this moment denticle causes the hard alloy columnar teeth early fallout to lose the effect of supporting hard alloy columnar teeth.The hard alloy columnar teeth that a kind of utility model beveled structure is arranged again, the patent No.: 962345776, the hard alloy columnar teeth junction area of its shortcoming pick denticle and utility model beveled structure is too little, after denticle is subjected to some wearing and tearing, denticle is just not enough to the support force of the hard alloy columnar teeth of utility model beveled structure, the umbrella shape position, hard alloy columnar teeth upper end of utility model beveled structure is fractureed usually, make pick initial failure, increased the replacing number of times, influence the operate as normal of digger, improved mining costs.
The utility model content
Problem to be solved in the utility model is the hard alloy columnar teeth of existing pointed cone cylindrical structure and the hard alloy columnar teeth of beveled structure, the technical problem that early fallout occurs and fracture.
In order to solve the problems of the technologies described above, the utility model designs a kind of digger pick carbide post tooth of new structure.It has a cone sphere top, middle part cylinder to be provided with termination, trench diameter and denticle upper end equal diameters, bottom by fluted small cylinder much is set constitutes than the middle part being little.Described cone sphere top, middle part cylinder and bottom small cylinder blow.
The utility model with there being technology to compare, described cone sphere top, middle part cylinder diameter and termination, denticle upper end equal diameters design like this and make hard alloy columnar teeth, protect denticle not frayed fully.Also increase the weld strength of the hard alloy columnar teeth of new structure, thereby the digger pick post dental transition of new structure is firmly connected on the denticle.Cause the pick can initial failure, thereby reduced the consumption of pick, reduced the number of times of changing the digger pick, improve the digger operating efficiency, reduced mining costs.
Description of drawings
Fig. 1 is a kind of new structure digger pick post tooth outline schematic diagram
Fig. 2 is a kind of new structure digger pick post tooth schematic top plan view
Fig. 3 is a kind of new structure digger pick post tooth and pick denticle combination schematic diagram
In the drawings: 1 top cone sphere, 2 middle part cylinders, 3 bottom small cylinders
4 pick bodies, 5 pick body cones, 6 scolders
The specific embodiment
Top cone sphere (1) and middle part cylinder (2) blow, middle part cylinder (2) and bottom small cylinder (3) blow simultaneously as shown in Figure 1.
New structure digger pick post tooth is used the high-frequency induction welder soldering tech as shown in Figure 3, makes pick by scolder (6) solid welding on the working position of pick body (4) upper end cone (5), and other machinings and heat treatment are constant.New structure digger pick post tooth; top cone sphere (1), middle part cylinder (2); fully pick cone (5) position is protected not frayedly, effectively bring into play the function of new structure digger pick post tooth, thereby improve the application life of digger pick.
Claims (3)
1, a kind of new structure digger pick post tooth, it is characterized in that: top has a cone sphere, middle part cylinder and bottom small cylinder to constitute.
2, new structure digger pick post tooth according to claim 1, it is characterized in that: described middle part cylinder cylinder is provided with groove.
3 new structure digger pick post teeth according to claim 1, it is characterized in that: described bottom small cylinder cylinder is provided with groove.
