Abstract
The utility model relates to a kind of string arc formulas to lack side structure winning machine cutting part device.Including cutting units shell, motor, internal drive system, drum shaft etc..The motor, transmission system, drum shaft are installed in cutting units shell, the cutting units shell is equipped with hinged earhole, the cutting units shell is equipped with oil cylinder hinge hole, the cutting units shell is equipped with string arc shape and lacks side, guarantee that cutting units shell outer circle is not interfered with transporter ledge when cutting units is swung around hinged earhole to fall when coalcutter work, the remaining coal seam of cleaning seat earth requires when meeting coal mining machine roller coal cutting.The utility model is designed reasonably, structure are simple, easy to use, when can solve some thin seam working surface mechanical coal minings, diameter of cylinder can not be increased because being limited by coal seam thickness, when coal mining roller can not place cleaning seat earth remain coal seam, scratch board conveyor cannot be promoted normally, the problem that be normally carried out coal work can not.
Description
Technical field
The utility model relates to a kind of winning machine cutting part devices, are Specifically a kind of scarce side structure coalcutters section of string arc formula
Cut part device.
Background technique
Existing girdle fully-mechanized coalface (see Fig. 1, Fig. 2), needs coalcutter, scratch board conveyor and liquid
Support equipped is pressed to cooperate, coalcutter, which shuttles to walk on scratch board conveyor using scratch board conveyor as track, coal cutting and coalings,
Transporter is responsible for transporting coal, and hydraulic support is responsible for working site supporting, when winning machine cutting part centered on hinged shaft to lower swing when,
By cutting units outer circle and scraper conveyer groove upper height limitation, roller outer rim cannot fall on floor undulation level, therefore
It can make scratch board conveyor that can not push ahead there are residual coal seam after coal mining machine roller coal cutting, coal work cannot be carried out continuously,
Need to increase coal mining machine roller diameter to solve, but for some thin seam working surfaces, if increasing diameter of cylinder again by coal
The limitation of thickness degree.
Utility model content
The purpose of the utility model is to provide a kind of string arc formulas to lack side structure winning machine cutting part device, increases cutting units
Bottom range, diameter of cylinder can not be changed and guarantee that roller outer rim can fall on floor undulation height, to solve to mine
Working face seat earth remaining coal seam when machine cylinder coal cutting solves coal-getter in this way, scratch board conveyor can continue to push ahead
The problem of production of looking unfamiliar can continuously recycle progress is (see Fig. 3, Fig. 4).
A kind of string arc formula lacks side structure winning machine cutting part device, including cutting units shell, motor, internal drive system,
String arc shape lacks side, drum shaft, hinged earhole, oil cylinder hinge hole etc., and the winning machine cutting part shell is equipped with string arc shape
Lack side.The motor is mounted in cutting units shell, and the transmission system is mounted in cutting units shell, the drum shaft installation
In cutting units shell, the cutting units shell is equipped with hinged earhole, and the cutting units shell is equipped with oil cylinder hinge hole.
Detailed description of the invention:

Specific embodiment
A kind of scarce side structure winning machine cutting part device of string arc formula, the motor (13), internal drive system (14), roller
Axis (16) is installed in cutting units shell (12), and the cutting units shell (12) is equipped with oil cylinder earhole (17), the cutting
Portion's shell (12) is equipped with hinged earhole (18), and the cutting units shell (12) is equipped with string arc shape and lacks side (15), for hiding
Keep away the interference with ledge (6) on scratch board conveyor (5).Make cutting units shell (12) around hinged earhole (18) swing fall when not
Interfere with scraper conveyer groove upper (6), increases cutting units whereabouts pivot angle, therefore, coal mining machine roller outer rim can fall on work down
Make on face seat earth (7), ensures that coal mining machine roller (2) can be with remaining coal on place cleaning seat earth (7) in this way
Layer (8) is carried out continuously coal work normally to guarantee that scratch board conveyor (5) and hydraulic support (4) normally promote,
And coal is adopted completely.
Claims (1)
1. a kind of string arc formula lacks side structure winning machine cutting part device, including cutting units shell (12), motor (13), internal drive
System (14), string arc shape lack side (15), drum shaft (16), oil cylinder hinge hole (17), hinged earhole (18), it is characterised in that:
The cutting units shell (12) is equipped with string arc shape and lacks side (15).
