Abstract
The invention discloses a cutting pick-adjustable shearer drum. A drum body (6) is provided with a plurality of clamp grooves (5), a plurality of cutting assemblies (2) with clamp blocks are installed in each of the clamp grooves (5), the clamp blocks are fitted with the clamp grooves, and the cutting assemblies (2) are axially adjustable in the clamp grooves (5). Compared with the prior art, the cutting pick-adjustable shearer drum has the characteristics that cutting assemblies of different specifications can be installed on one drum body, and the cutting assemblies are adjustable in the clamp grooves, thereby greatly expanding the range of coal mining; for different coal quality or user requirements, coal of different block rates can be mined by adjusting cutting positions or replacing the cutting with no need of on-site replacement of the drum and hiring of a crane; meanwhile, for coal of different quality mined in the open air or coal of different block rates required by users, costs for remaking a drum, installing the drum and hiring a crane are eliminated.
Description
Technical field
The present invention relates to a kind of coal mining machine roller, especially a kind of pick adjustable coal cutter cylinder.It can make the strip coal mining eedle different atures of coal, different coal mining piece rate be required to carry out the coal mining machine roller in cut coal seam.
Background technology
As everyone knows, the layout of pick is according to different atures of coal on the strip coal mining machine cutting drum, and the coal of the piece rate that cut is different designs.When ature of coal difference or user had difference to require to the piece rate of coal, coal machine manufacturer often again made pick and arranges different cutting drums, satisfies user's demand.Usually after the user buys a coal-winning machine, also want different cutting drum customized.Expense is high, and the cycle is long, and the installation of on-the-spot cylinder is inconvenient, need rent crane, drop into a large amount of financial resources, material resources, manpower and time.
Therefore, designing a kind of pick adjustable coal cutter cylinder, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of pick adjustable coal cutter cylinder.
The technical scheme that the present invention solves its technical problem is:
Pick adjustable coal cutter cylinder is processed with some clamp bar slots at barrel, several all is installed with the pick assembly of fixture block in every clamp bar slot, fixture block and draw-in groove coupling, and pick assembly axial location in draw-in groove is adjustable.
As a preferred embodiment of the present invention, described draw-in groove is dovetail groove, and described fixture block is dovetails, several all is installed with the pick assembly of dovetail slide block in every dovetail groove, dovetail slide block and dovetail groove coupling, pick assembly axial location in dovetail groove is adjustable.
As a preferred embodiment of the present invention, described dovetail slide block is top shoe, and described pick assembly is made of pick, toothholder and top shoe, and toothholder and top shoe are welded and fixed; Pick is connected with toothholder is replaceable, also be provided with sliding block at dovetail groove, axial unthreaded hole is arranged on the top shoe, axial screw is arranged on the sliding block, the link of top shoe and sliding block is the inclined-plane of coupling, top shoe tightens together by bolt and sliding block, and the inclined-plane of top shoe and sliding block tightly fits together, fastening by bolt, move on the top shoe, sliding block moves down, thereby upper and lower slide block and barrel tensioner are together, thereby the pick assembly is fixed on the barrel.
When needing to adjust the pick position, bolt is unclamped, make the pick assembly move to the precalculated position, tight a bolt again, fixedly toothholder.
As a preferred embodiment of the present invention, described pick assembly has a plurality of models, and its top shoe of pick assembly of a plurality of models is the same, for toothholder, the assembling dimension pick that welds different size forms.
Compared with prior art, the present invention is owing to can install the pick assembly of different size on a barrel, and pick assembly position in groove is adjustable, therefore expanded greatly the scope of mining, for different atures of coal or customer requirements, but can arrange or change by adjusting pick the coal of pick extraction different masses rate, also remove the on-the-spot expense of changing the loaded down with trivial details of cylinder and renting crane from, the coal of the different atures of coal of open pit mine or user's request different masses rate has simultaneously relatively saved expense and the installation of again making cylinder, has rented the expense such as crane.

The specific embodiment
As shown in the figure, pick adjustable coal cutter cylinder is processed with some clamp bar slots 5 at barrel 6, several all is installed with the pick assembly 2 of fixture block every clamp bar slot 5 is interior, fixture block and draw-in groove coupling, and pick assembly 2 is adjustable at draw-in groove 5 interior axial locations.
Described draw-in groove 5 is dovetail groove, and described fixture block is dovetails, several all is installed with the pick assembly 2 of dovetail slide block every dovetail groove 5 is interior, dovetail slide block and dovetail groove 5 couplings, and pick assembly 2 is adjustable at dovetail groove 5 interior axial locations.
Described dovetail slide block is top shoe 2-3, and described pick assembly 2 is made of pick 2-1, toothholder 2-2 and top shoe 2-3, and toothholder 2-2 and top shoe 2-3 are welded and fixed; Pick 2-1 is connected with toothholder 2-2 is replaceable, in dovetail groove 5, also is furnished with sliding block 3, axial unthreaded hole is arranged on the top shoe 2-3, it is axial screw on the sliding block 3, the link of top shoe 2-3 and sliding block 3 is the inclined-plane of coupling, top shoe 2-3 tightens together by bolt 1 and sliding block 3, the inclined-plane of top shoe and sliding block tightly fits together, fastening by bolt, move on the top shoe, sliding block moves down, thereby upper and lower slide block and barrel tensioner are together, thereby the pick assembly is fixed on the barrel.
Described pick assembly 2 has a plurality of models, and its top shoe of pick assembly 2-3 of a plurality of models is the same, for toothholder 2-2, the assembling dimension pick that welds different size forms.
When needing to adjust the pick position, only need bolt 1 is unclamped, make the pick assembly move to the precalculated position, tight a bolt, fixedly toothholder gets final product.
