The end of the pick is installed with the cylindrical wear body extended along the longitudinal direction, the one of the cylindrical wear body
Side is wrapped in pick matrix.
The cylindrical wear body is assembled along the longitudinal direction by multiple wear body piecemeals.
Have on pick and be additionally provided with the pick attachment structure for being used for being connected with pick bar, pick for making pick and pick bar
Positioning hole with installation.
The technical scheme of the utility model tamping pickaxe is：A kind of tamping pickaxe, including pick and pick bar, pick include thickness along left and right
It is fixed on the flat-shaped pick matrix that direction extension, width extend along the longitudinal direction, the left surface and right flank of pick matrix
Having between the two neighboring wear plate at least two wear plates, same side has expansion avoiding seam.
Left surface is the consistent planar structure of gradient, and left and right side is arranged symmetrically, and left and right side is provided with along height side
To two rows described in wear plate, often row include at least two spaced apart wear plates along the longitudinal direction.
The end of the pick is installed with the cylindrical wear body extended along the longitudinal direction, the one of the cylindrical wear body
Side is wrapped in pick matrix.
The cylindrical wear body is assembled along the longitudinal direction by multiple wear body piecemeals.
Have on pick and be additionally provided with the pick attachment structure for being used for being connected with pick bar, pick for making pick and pick bar
There is the pick bar attachment structure for being used for being connected with pick on positioning hole with installation, pick bar.
The beneficial effects of the utility model are：Between wear plate exist expansion avoiding seam, in use, when wear plate be heated it is swollen
After swollen, expansion avoiding seam can accommodate the part that wear plate expansion is extended, and provide space for the expansion of wear plate, prevent adjacent resistance to
Extruding is come in contact between grinding and causes wear plate to come off too early.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model tamping pickaxe；
Fig. 2 is the front view of pick in Fig. 1；
Fig. 3 is Fig. 2 top view.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of tamping pickaxe of the present utility model, as shown in Figure 1 to Figure 3, tamping pickaxe includes pick 1 and pick bar 2,11 is
Sheet diamond polycrystal, 12 be expansion avoiding seam, and 13 be circular diamond polycrystal, and 14 be positioning hole, and 15 be pick matrix.
As can be seen from Figure, it is in flat-shaped profile that pick 1 is overall.
In the present embodiment, pick 1 and the split of pick bar 2 are set, together with pick 1 is bolted with pick bar 2, in pick
There is the pick attachment structure being connected with pick bar 2 on 1, there is the pick bar attachment structure being connected with pick 1 on pick bar 2.14 are
Positioning hole, can make pick and pick bar Matching installation.In actual use, pick 1 is frayed larger to cause the use longevity of pick
Life is shorter, and pick 1 and pick bar 2 are made into split-type structural, after pick 1 is damaged and scrapped, changes pick 1, without
Pick 1 and pick bar 2 are all changed, is easy to be individually replaced pick.
Left and right directions in diagram 2 is short transverse, and above-below direction is width.Above-below direction in diagram 3
As thickness direction.The two sides of the thickness direction of pick matrix 15 is the consistent plane of symmetrically arranged gradient, thickness in diagram 3
It is fixed with the two sides in direction in sheet diamond polycrystal 11, the present embodiment, the quantity of sheet diamond polycrystal 11 is
Two rows that are multiple and being divided into short transverse, often arrange and are equipped with multiple sheet diamond polycrystals spaced in the width direction
11, the mode that sheet diamond polycrystal 11 is fixed on pick matrix 15 is to inlay.In other embodiments, it can be used
His mode is fixed, and such as welds.There is expansion avoiding seam 12, in sheet between adjacent sheet diamond polycrystal 11
During 11 expanded by heating of diamond polycrystal, expansion avoiding seam 12 provides space for the expansion of sheet diamond polycrystal 11, makes phase
Keep independent between two adjacent sheet diamond polycrystals 11, be not in mutual extruding and cause the phenomenon come off too early to go out
It is existing.
Circular diamond polycrystal 13 is also inlaid with the end of pick 1, circular diamond polycrystal 13 is in the width direction
Extension.The side of circular diamond polycrystal 13 is wrapped in pick matrix 15, and hold is strong, the circular Buddha's warrior attendant in severe impact
Stone polycrystal 13 is not fallen out.As can be seen that circular diamond polycrystal 13 is by multiple circular diamond polycrystals point in Fig. 2
Axial direction of the block along circular diamond polycrystal（That is width）Assemble.
