Description

A kind of cleaning up excrement machining chisel hits instrument

Technical field

The utility model belongs to shit remover machinery tools field more particularly to a kind of cleaning up excrement machining chisel hits instrument.

Background technology

At present, tradition hits cutter to provide the chisel of centric(al) impact and broken chisel function, knife bar of the structure comprising a column type, The chisel for being formed in the knife bar front end hits portion and takes shape in the connecting portion of the knife bar rear end.Connecting portion is connecting power work Tool either handle.Chisel, which hits its shape of portion, can be conico-acuminate with development length or be short cone or pyramid-shaped.Nothing By being that coniform or pyramid-shaped chisel hits portion, surface is all closing and smooth.

Chisel, which hits cutter, can transfer an entity structure one impact force, and the entity structure is in by one cutting area of shock surface formation. Foregoing coniform and pyramid-shaped chisel hits portion can provide the impact force of aggregation for the cutting of entity structure, but singly have impact Power is inadequate, and chisel, which hits portion, can just cutting operation be made to get twice the result with half the effort to providing comparable destructive power by shock surface.It is however preceding It states surface-closed and smooth chisel hits portion to limited by the structure destructiveness of shock surface.In addition, dig destroyed in the process open Chisel area can generate chip, and the shallow cutting area of table easily excludes its chip, but deeply dig the chip in area instead easily by table The face closure and smooth chisel portion of hitting is blocked, chip can not be successfully and exclude from digging area, and cutting will be increased in area is dug by accumulating Resistance.When facing more and more big cutting resistance, operator can attempt to ask to solve this in a manner of improving impact force It inscribes, then chisel hits cutter and bears more and more big impact force and reaction force, is easy to impaired, short life.

The content of the invention

The utility model is intended to provide a kind of strong and durable cleaning up excrement machining chisel of impulse force and hits instrument.

In order to solve the above technical problems, in the utility model cleaning up excrement machining chisel hit instrument technical solution it is as follows：

Cleaning up excrement machining chisel hits instrument, and including drilling rod, what the afterbody of drilling rod was equipped with to receive to hit is hit portion, drilling rod Head be equipped with angle between drill rod axis chisel at an acute angle and hit knife face, chisel hits the front side seamed edge of knife face and is hit for angular chisel Cutting edge.

Chisel hits knife face and has two sides and be mutually angular distribution, and chisel hits cutting edge and mutually passes through position positioned at what two chisels hit knife face.

Two chisels hit axisymmetrical of the knife face on drilling rod.

The endpiece of drilling rod includes the prismatic gripping section positioned at drilling rod rear, and the circumscribed circle diameter of gripping section is more than drilling rod Major diameter.

Gripping section is the hexagonal prisms of orthohexagonal, and the rear of gripping section is co-axially located at by the portion of hitting, and the portion of being hit is one and folder Hold the coaxial anvil block of section.

The beneficial effects of the utility model are：

Knife face is hit with chisel and forms knife edge structure on the head of drilling rod, convenient for being pierced under impact force action under workpiece surface, The helicla flute on drilling rod surface can play the role of chip removal and loss of weight simultaneously, increase impact amplitude, thus the chisel hits instrument with punching Hit the advantages of power is strong and durable.

Description of the drawings

Fig. 1 is that the chisel of the utility model hits the stereoscopic schematic diagram of instrument；

Fig. 2 is the front view of Fig. 1.

Specific embodiment

The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that it is not rushing In the case of prominent, the feature in embodiment and embodiment in the utility model can be mutually combined.

Cleaning up excrement machining chisel hits the embodiment of instrument in the utility model：As depicted in figs. 1 and 2, which hits kit Drilling rod 1 is included, what the afterbody of drilling rod 1 was equipped with to receive to hit is hit portion 2, and the head of drilling rod 1 is equipped between 1 axis of drilling rod Angle chisel at an acute angle hits knife face 3, and chisel hits the front side seamed edge of knife face 3 and hits cutting edge 4 for angular chisel.Chisel, which hits knife face 3, has two sides simultaneously It is mutually angular distribution, chisel hits cutting edge 4 and mutually passes through position positioned at what two chisels hit knife face 3.Two chisels hit axis pair of the knife face 3 on drilling rod 1 Claim.

The endpiece of drilling rod 1 includes the prismatic gripping section 5 positioned at 1 rear of drilling rod, and the circumscribed circle diameter of gripping section 5 is more than The major diameter of drilling rod 1.Gripping section 5 is the hexagonal prisms of orthohexagonal, and the rear of gripping section 5 is co-axially located at by the portion that hits 2, is hit portion 2 For an anvil block coaxial with gripping section 5.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that： It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc. With replacement；And these modifications or replacement, the essence of appropriate technical solution is not made to depart from various embodiments of the utility model technology The spirit and scope of scheme.
