Abstract

The present invention relates to a mineral cutting or crushing cutter, specifically to a conical pick with a non-arc conical surface carbide tip and an elasticity function structure, and belongs to the field of cutting or crushing equipment for coal mines and other minerals. The existing conical pick structure can affect pick consumption, specific energy of cutting, and a working life. The present invention provides a novel pick, wherein the carbide tip of the pick has a non-arc conical surface structure, and an elastic member is arranged between a pick unit and a pick sleeve to form axial coupling so as to produce a relatively axial movement. According to the present invention, during coal crushing, effects of the blade of the flat pick can be provided, crushing efficiency can be increased, and strength and powerful crushing ability of the conical pick can be enhanced so as to easily achieve coal collapse and pick self-rotation; and the coupling elastic member is arranged between the pick and the pick sleeve, such that an axial displacement of the pick can be regulated so as to avoid excessive partial wear of the pick, and enhance coal crushing ability and pick self-rotation reliability.

Description

Pick-shaped cutter with non-circular arc taper seat hard alloy head and spring function structure
Technical field
Patent of the present invention relates to cut or break mined material equipment such as mining machinery, is specifically related to a kind of pick (cutter) for operating mechanism's cut or break mined material (coal, rock).
Background technology
Pick-shaped cutter has been widely used on the plant equipment such as digging of Coal Production (as drum shearer and partial-size tunneling machine), it is the key components and parts in the mining machinery operating mechanism, its pick and tooth cover together are assembled on the toothholder, and toothholder is welded on according to certain arrangement regulation on the circumference of operating mechanism (operating mechanism mostly is revolving bodies such as cylinder or round platform), under the driving of other actuating unit, realize rotation and the feed motion of operating mechanism, mineral such as incision coal petrography, pick is directly acted on the coal petrography, and its structural performance and quality directly have influence on the pick consumption of coal production, specific energy of cutting and working life.Pick-shaped cutter mainly is made up of carbide bit and alloy steel denticle etc., conventional pick-shaped cutter carbide bit is the form of structure of taper seat or circular arc taper seat, the coupling method of carbide bit and cutter hub mostly adopts methods such as soldering processes or castingin.Basic demand to the pick performance: be set in carbide bit on the denticle when mineral such as the various coal petrographys of cut, can not come off and fragmentation, and the structure of pick and quality, can directly have influence on consumption, specific energy of cutting and the working life of pick, the pick-shaped cutter carbide bit all adopts the combining form of cylinder circular cone at present, and cutting resistance is bigger than normal, energy consumption is high, and the reliability of pick spin is low, cause the pick eccentric wear, make the pick premature failure.From the functional reliability and the reduction specific energy of cutting that improve pick, reasonably carbide bit planform, pick structure and mounting structure are particularly important.
Summary of the invention
[0003] the problem to be solved in the present invention is at above-mentioned deficiency, propose a kind of novel pick, the hard alloy head of pick has non-circular arc (as many prismatics) taper seat structure and spring function structure (being provided with the axial connecting mode of flexible member between pick and the tooth cover).When usefulness of the present invention is broken coal petrography, can bring into play the effect of the blade of knife shape cutter teeth, improve crushing efficiency, can embody intensity and the powerful broken ability of pick-shaped cutter again; Simultaneously, along with the difference of external applied load, flexible member can be regulated the axial displacement of pick, produces the dynamic impulsion effect vertically, strengthens the ability of broken coal petrography and the reliability of pick spinning (avoiding the excessive eccentric wear of pick).The present invention is specially adapted to soft, toughness coal petrography.
In order to solve the problems of the technologies described above, the invention provides a kind of pick of following structure, its structure is formed: hard alloy head, pick denticle, elastic expansion split ring, flexible member, pick tooth cover, soldered seam.
Hard alloy head has as many prismatics conical surface conical structure, by soldered seam or other ways and means hard alloy head is connected firmly on the pick denticle, forms complete pick unit.The pick unit plays the blade effect, and its compressive strength is beneficial to the spinning of conquassation coal petrography and pick greater than the tensile strength of coal petrography.Be provided with flexible member in axial between pick tooth cover and the pick denticle, the elastic expansion split ring is enclosed within on the pick unit, the pick unit is contained in the pick tooth cover endoporus, be used for fixing pick, avoid pick unit separating tooth cover vertically, flexible member one end is supported on pick tooth cover bottom, and the other end withstands on pick denticle bottom.Pick-shaped cutter with spring function structure, the pick denticle moves along the interior axially bored line of pick tooth cover with the variation of external applied load, and flexible member is compressed, the suffered impact force of buffering pick, reduce non-circular arc taper seat hard alloy head wearing and tearing, thereby increase the life-span of pick-shaped cutter.Pick tooth cover is coal or the dismounting pick unit that enter pick tooth cover be used to removing for revolving body and bottom have five holes.
Innovation part of the present invention is that the hard alloy head of pick has non-circular arc taper seat structure, when making pick-shaped cutter fragmentation coal petrography, can bring into play the effect of the blade of knife shape cutter teeth, improve crushing efficiency, can embody intensity and the powerful broken ability of pick-shaped cutter again; Pick denticle and pick tooth inner room are provided with the axial connecting mode of flexible member, have made it to move to axial, and strengthen the ability of broken coal petrography and the reliability of pick spinning.
Description of drawings
Fig. 1 is the pick-shaped cutter structural representation that the present invention has non-circular arc taper seat hard alloy head and spring function structure, and Fig. 2 is the partial enlarged drawing among Fig. 1, Fig. 3 be A among Fig. 2 to view, Fig. 4 is along the profile of B-B among Fig. 2.Fig. 5 is the vertical view of pick tooth cover among Fig. 1.Wherein 1 is hard alloy head, the 2nd, pick denticle, the 3rd, elastic expansion split ring, the 4th, flexible member, the 5th, pick tooth cover, the 6th, soldered seam.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are elaborated.
The hard alloy head 1 of pick-shaped cutter is the member that directly acts on coal petrography, broken coal petrography, adopt soldered seam 6 and other ways and means that hard alloy head 1 is connected firmly on the pick denticle 2, form complete pick unit, be provided with flexible member in axial between pick tooth cover 5 and the pick denticle 2, elastic expansion split ring 3 is enclosed within on the pick unit, and the pick unit is contained in the pick tooth and overlaps in 5 endoporus, be used for fixing pick, avoid pick unit separating tooth cover vertically.At work, pick-like bit of the present invention is assembled on operating mechanism's circumference, drives operating mechanism by other actuating unit and realize rotation and feed motion, mineral such as incision coal petrography.
Certainly; above-mentioned explanation is not limitation of the present invention; the present invention also is not limited only to above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement; also belong to protection scope of the present invention; as the quantity of many prismatics conical surface of hard alloy head, the type of flexible member (butterfly spring, cylindrical spring etc.).
