Aforesaid bushhammer, the height of the coniform thing of wherein said hammer tooth is 12-14mm.

Aforesaid bushhammer, wherein said respectively to hammer tooth distance each other into shape be 4.5～5.5mm.

Aforesaid bushhammer, the carbide alloy of wherein said hammer tooth is to be main component with the carbide of high rigidity refractory metal (WC, TiC) micron powder, with cobalt (Co) or nickel (Ni), molybdenum (Mo) is binding agent, the sintered metal product that sintering forms in vacuum drying oven or hydrogen reducing furnace.

Aforesaid bushhammer, the height of wherein said hammer tooth capsule is 10～11mm.

It is 24mm * 27mm * 30mm that aforesaid bushhammer, wherein said hardy hole are of a size of.

Aforesaid bushhammer, the length of wherein said hammer handle is for being 300～500mm.

After adopting technique scheme, of the present inventionly be used to cut a hole mao bushhammer of concrete face and have the following advantages:

1, the hammer tooth hardness of being made by hard alloy steel is big, wear-resisting, shock-resistant, intensity is high, be difficult for loss;

2, simple in structure, easy to make, increase work efficiency;

3, reduce labor intensity of operating staff, strengthen security.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing thereof the present invention is illustrated further.

Now see also Fig. 1, be the head construction schematic diagram of the bushhammer of the embodiment of the invention, Fig. 2 is the A-A cut-away view of Fig. 1, and Fig. 3 is the B-B cut-away view of Fig. 1.As shown in the figure, described hammer tooth 1 is the coniform thing that is made by YG8C trade mark carbide alloy, be arranged to five rows, every row is five, reach one group and be foursquare hammer tooth 1 structure, directly to contact with the concrete face, the height of described hammer tooth 1 coniform thing is 11.5mm, and described respectively to hammer tooth 1 distance each other into shape be 5mm;

Described hammer tooth capsule 2 is to pile up the parts that form fixing hammer tooth 1 by brazing, similar animal gum, and described hammer tooth capsule 2 links together one group of hammer tooth 1 securely, so both ensured and hammered the whole stressed of tooth into shape, formed the transition of hammer tooth with the hammer body simultaneously, the height of described hammer tooth capsule 2 is 10mm;

Described hammer body 3 is a kind of No. 45 steel castings, form the counterweight of whole hammer, and be the significant points that is connected with hammer handle, the alveolus of the similar animal of hammer body head, by the fixedly connected hammer tooth of brazing capsule 2, an end of hammer body 3 will be hammered tooth capsule 2 into shape and link together with 2 brazings of hammer tooth;

Described hardy hole 4 is a rectangular through-hole, is arranged on the inside of hammer body 3, near with the opposite the other end of hammer tooth 1, it is 24mm * 27mm * 30mm that described hardy hole 4 is of a size of;

Fig. 4 is the hammer handle structural representation of the embodiment of the invention.Described hammer handle 5 is wooden handles, and the one end can insert in the described hardy hole 4, so that hammer handle 5 links into an integrated entity with described hammer body 3.Can be used to install the hammer handle of different length, be convenient to the cutter hair of different parts concrete face, operating personnel are used and indefatigability in varying environment.The length of described hammer handle 5 can be selected the short handle of 300mm for use, or the long handle of 500mm.

Of the present invention when being used to cut a hole mao bushhammer of concrete face and can using, operating personnel may stand in case beam-ends head the place ahead or directly carry out concrete face cutter hair above the case back plate, and operating personnel's personal safety is effectively guaranteed like this, and is beneficial to work more.

Require according to case beam concrete face cutter hair: hair need not cut a hole in the position of 1cm around the position of the close about 2cm of concrete seamed edge and the reinforcing bar extending area, and hair must be cut a hole in all the other positions, and the requirement of cutter hair cuts surperficial laitance, exposes coarse aggregate in the concrete, cuts a hole hair and can not destroy the concrete seamed edge.

Therefore at the general short handle bushhammer that adopts 300mm of case beam-ends head cutter hair, at first the reinforcing bar that the case web is stretched out is a little outwards pulled curvedly, can get final product by handled easily; And the general long handle bushhammer that adopts 500mm of flange plate side cutter hair, operating personnel may stand in back and operate, and the flange plate reinforcing bar need not be handled before the cutter hair; The beam body cutter hair time is preferably in carries out after beam phantom plate is removed immediately, overlong time, and case beam concrete strength raises, and the hair hammer uses to be needed firmly just can produce laitance greatly, also excessive to the wearing and tearing of hair hammer tup.

Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique under the situation that does not break away from the spirit and scope of the present invention, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
