Abstract
The utility model relates to a rock cutting pick for a coal mining machine used in a coal mine working surface, belonging to a cutting part for the coal mining machine of the coal mine working surface. The rock cutting pick is provided with a cutting pick body and a wedge pick point, wherein the wedge body comprises a pick handle and a pick sleeve; the pick top end of the pick handle is of a transitional and conical fat structure; the top end of the pick handle is provided with a wedge pick point; and the tail end of the pick handle is connected with the pick sleeve. The rock cutting pick mainly solves the problem that the coal mining machine causes abrasion when cutting rocks on the coal mine working surface, reduces the amount of powder coal generated when the coal mining machine works and respirable air-carrying dust, and reduces the noise generated when the coal mining machine cut coals. The rock cutting pick has the advantages in energy consumption, pick abrasion, cutting force, crushing, and the like.
Description
Technical field
The utility model relate to a kind of be used for the coal mine work area coal-winning machine cut the rock pick, be the cutting part of coal mine work area coal-winning machine.
Background technology
Working surface coal mining machine is the nucleus equipment of fully-mechanized mining working, and major function is broken coal and coalings that pick is installed on the coal mining machine roller, is the important process parts of coal-winning machine.In the seam mining process, often run into spoil, many times need to cross by force cash, very big to the wearing and tearing of pick.In addition, coal-winning machine can produce a large amount of coal dusts in the coal mining process, and this novel pick has reduced the generation of coal dust from the source.
The utility model content
The purpose of this utility model be to provide a kind of be used for the coal mine work area coal-winning machine cut the rock pick, mainly solve wearing and tearing and the dust problem of coal-winning machine when coal mine work area cut rock.
The technical solution of the utility model:
A kind of be used for the coal mine work area coal-winning machine cut the rock pick, it is characterized in that: this cuts the rock pick and is provided with pick body, wedge shape crown, and the pick body comprises pick handle, pick cover, and the tooth tip of pick handle is a transition taper flat structure, this end is installed the wedge shape crown, and the pick handle is terminal to be connected with the pick cover.
Described be used for the coal mine work area coal-winning machine cut the rock pick, pick handle end is provided with backing pin, has the backing pin groove in the pick cover, the pick handle is plugged in the pick cover, backing pin on the pick handle and interior corresponding cooperation of backing pin groove of pick cover.
Described be used for the coal mine work area coal-winning machine cut the rock pick, backing pin is a plane flat structure.
Described be used for the coal mine work area coal-winning machine cut the rock pick, the pick handle is provided with the inner support jump ring, has in the pick cover and the inner support jump ring groove of clamping mutually.
The beneficial effects of the utility model:
1, the utility model cuts the rock pick and is provided with pick body, wedge shape crown, the pick body comprises pick handle, pick cover, and the tooth tip of pick handle is a transition taper flat structure, and this end is installed the wedge shape crown, the pick handle is terminal to be connected the big problem of wear extent when efficiently solving the coal-winning machine coal cutting with the pick cover.
Coal dust that has produced when 2, the utility model has effectively reduced coal-winning machine work and the dust quantity that can suck.
Noise when 3, the utility model effectively reduces the coal-winning machine coal cutting.
4, the utility model has effectively reduced energy consumption.
5, the utility model has effectively improved the cutting capacity of coal-winning machine.
6, the utility model has effectively improved the breaking capacity of coal-winning machine.
Description of drawings
Fig. 1 cuts rock pick structure chart for the utility model; Wherein, Fig. 1 (a) is a front view; Fig. 1 (b) is a vertical view; Fig. 1 (c) is a lateral view.
Fig. 2 is the work sheet of the utility model pick and the physical dimension figure of wedge shape crown; Wherein, Fig. 2 (a) is for cutting the rock pick; Fig. 2 (b) is the crown front view; Fig. 2 (c) is the crown vertical view.
Among the figure, 1 wedge shape crown; 2 pick handles; 3 pick covers; 4 backing pins; 5 inner support jump rings.
The specific embodiment
Shown in Fig. 1 (a)-Fig. 1 (c), the rock pick that cuts that the utility model is used for the coal mine work area coal-winning machine is provided with pick body and wedge shape crown 1, the pick body is pick handle 2, pick cover 3, backing pin 4, inner support jump ring 5 formations, pick handle 2 tooth tip are transition taper flat structure, this end is installed wedge shape crown 1, and pick handle 2 ends are connected with pick cover 3.Pick handle 2 ends are provided with backing pin 4, backing pin 4 is a plane flat structure, has the backing pin groove in the pick cover 3, and pick handle 2 is plugged in pick cover 3, backing pin 4 on the pick handle 2 overlapped for 3 interior corresponding cooperations of backing pin groove with pick, can prevent that pick handle 2 and pick cover 3 is relative to radially rotating; Also be provided with inner support jump ring 5 on the pick handle 2, have in the pick cover 3 and inner support jump ring 5 groove of clamping mutually, can guarantee that pick handle 2 and pick cover 3 move to axial gap (gap that relatively moves is very little, and leaving closely spaced purpose is to cushion impact force excessive when cutting hard rock).Thereby realization pick cover is locked better with the pick handle and is connected.In the utility model, the tooth tip of pick handle 2 and wedge shape crown 1 can adopt silver-brass solder method welding.
Shown in Fig. 2 (a)-Fig. 2 (c), to satisfy during installation that the utility model cuts the axis of rock pick and the angle of coal mining machine roller radial direction is 50 °, pick handle 2 is relatively-stationary (pinning with inner support jump ring 5 and backing pin 4) degree of freedom without spin with pick cover 3, again pick cover 3 is fixed on (full degree of freedom constraint) on the mounted pick box, specific measures for implementation can be with latch or other feasible pattern.
Wherein, to cut the physical dimension of rock pick crown 1 as follows for the utility model:
Tooth angle c=70 °;
Cut basil a=10 °;
Relief angle b=10 °;
Angle of shock d=50 °;
Crown thickness e=10mm;
Crown radius of corner R0.5mm;
Material: WC-Co carbide alloy;
Bottom width f=34mm;
Height g=18mm;
Rake length h=29mm;
Hypsokinesis face length degree i=30.5mm.
The wedge shape crown that cuts the rock pick of the present utility model is sharp, and specific energy is little, and cut keeps the sharp keen time long, and fineness number increases.After crown wearing and tearing, still can guarantee the positive basil and the relief angle of cutting, pick wear area and wear angle are less, and gentle year dust of fine coal is less.
