Abstract
The utility model relates to a kind of middle part chute more particularly to a kind of adjustable middle part chutes for transporting coal during seam mining.The utility model is made middle part chute adjustable angle, is shoveled coal convenient for ramp plate by setting hydraulic cylinder and support plate, is prevented from deviateing bottom plate in the chute progradation of middle part, is influenced Coal Transport efficiency.The utility model includes hydraulic cylinder, support plate, the fixed ramp plate of chute first end, the fixed spillplate in chute second end top, the chute bottom hinged support plate, hinged hydraulic cylinder in the middle part of chute second end, hydraulic cylinder push rod and support plate are hinged, fixed to the inclined nozzle in coal wall side at the top of spillplate.
Description
Technical field
The utility model relates to a kind of middle part chute more particularly to it is a kind of for during seam mining transporting coal it is adjustable
Chute in the middle part of formula.
Background technique
The middle pan of scraper conveyor that traditional comprehensive mechanical coal working face uses use separate structure, spillplate,
Ramp plate and intermediate link slot are bolted together, wherein intermediate link slot includes middle plate and two sections of ledges, two sections of slots
Side is welded into one by middle board group.
In the prior art, design has the slightly lower part in chute baseplane than in the middle part of usually at ramp plate shovel tip, this
Sample just guarantees that middle part chute has a downward component when elapsing forward, so that middle part chute is advanced always along landing ground and by ground
Coal shovel rise be loaded into groove body.The size of size drag conveyor coal-spading device directly affects the effect shoveled coal, size scraper plate
Conveyer coal-spading device is too small, and chute downward component in middle part is small, will be allowed to upwards " drift " when middle part chute elapses forward
Ground is left, has a large amount of coal that cannot load, and will affect the working condition of whole equipment.Size drag conveyor coal-spading device
Excessive, with regard to big, middle part chute the more will be walked the more deep downward component to underground, increase the resistance of advance, influence normally to produce.
Utility model content
The purpose of this utility model is that propose a kind of adjustable middle part chute, by the way that hydraulic cylinder and support plate is arranged,
Make middle part chute adjustable angle, shovel coal convenient for ramp plate, prevents from deviateing bottom plate in the chute progradation of middle part, influence Coal Transport
Efficiency.
The utility model includes hydraulic cylinder, support plate, the fixed ramp plate of chute first end, the fixed gear in chute second end top
Coal plate, the chute bottom hinged support plate, the hinged hydraulic cylinder in chute second end middle part, hydraulic cylinder push rod and support plate are hinged,
It is fixed to the inclined nozzle in coal wall side at the top of spillplate.
After coalcutter coal cutting, coal cinder drops down onto bottom and forms float coal, and ramp plate is needed to clear up to the chute of middle part, when floating
When coal is more, ramp plate is also easy to produce downward component by coal ghost image sound, so that middle part chute the more is walked the more deep to underground, advance resistance increases
Greatly, it influences normally to produce；When float coal is less, makes middle part chute upwards " drift ", and then be detached from ground, make bottom coal can not
It transports.
Hydraulic cylinder initial position keeps support plate holding horizontal, when the amount of shoveling coal increases, adjusts hydraulic cylinder push rod and shrinks, make to shovel
Coal plate tilts upwards, reduces the advance resistance of middle part chute, prevents middle part chute from the more walking the more deep to underground；When the amount of shoveling coal is reduced
When, float coal lighter in weight, easily make middle part chute upwards " drift ", and then be detached from ground, adjust hydraulic cylinder contraction, make ramp plate to
Lower inclination prevents middle part chute upwards " drift ", is detached from ground.Fixed nozzle at the top of spillplate, nozzle are connected to water supply pipe,
It sprays water during shoveling coal to working face side, reduces coal dust and generate.
The chute includes plate in chute, chute bottom plate, baffle, and plate and chute bottom plate are by being arranged two in chute
The baffle of side is fixedly connected.
The chute bottom plate and support plate are hinged, and support plate least significant end is higher than ramp plate least significant end, hydraulic cylinder side and gear
Board slot side is hinged.
The beneficial effects of the utility model are:
(1) adjustable middle part chute described in the utility model, is provided with hydraulic cylinder and support plate, can be according to actually going out
Coal amount adjusts angle of shoveling coal, and improves efficiency of shoveling coal；
(2) adjustable middle part chute described in the utility model, is provided with nozzle, and nozzle is connected to water supply pipe, is subtracted
Few coal dust generates.
Detailed description of the invention
Fig. 1 is a kind of example structure schematic diagram；
In figure: 1, ramp plate；2, spillplate；3, hydraulic cylinder；4, support plate；5, nozzle；6, plate in chute；7, chute bottom
Plate；8, baffle.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, adjustable middle part chute described in the utility model, including hydraulic cylinder 3, support plate 4, chute
Ramp plate 1, the fixed spillplate 2 in chute second end top, the chute bottom hinged support plate 4, chute second end are fixed in one end
The hinged hydraulic cylinder 3 in middle part, 3 push rod of hydraulic cylinder and support plate 4 are hinged, are fixed at the top of spillplate 2 to the inclined nozzle 5 in coal wall side,
The chute includes plate 6 in chute, chute bottom plate 7, baffle 8, and plate 6 and chute bottom plate 7 are by being arranged in two sides in chute
Baffle 8 be fixedly connected, specifically, the chute bottom plate 7 and support plate 4 are hinged, 4 least significant end of support plate is higher than ramp plate
1 least significant end, 3 side of hydraulic cylinder and baffle 8 are hinged.
3 initial position of hydraulic cylinder keeps 4 holding of support plate horizontal, when the amount of shoveling coal increases, adjusts 3 push rod of hydraulic cylinder and shrinks,
It tilts ramp plate 2 upwards, reduces the advance resistance of middle part chute, prevent middle part chute from the more walking the more deep to underground；When the amount of shoveling coal
When reduction, float coal lighter in weight adjusts hydraulic cylinder 3 and shrinks, tilts down ramp plate 1, prevents middle part chute upwards " drift ",
It is detached from ground, 2 top fixed nozzle 5 of spillplate, nozzle 5 is connected to water supply pipe, to one side spray of working face during shoveling coal
Water reduces coal dust and generates.
The utility model use process is as follows described: after coalcutter coal cutting, fall and slipped at middle part using ramp plate cleaning
The float coal of front of the slot is influenced by mining conditions are different with the every knife coal cutting thickness of coalcutter, and float coal size varies in weight, and works as float coal
When more, adjust hydraulic cylinder push rod and shrink, tilt ramp plate upwards, reduce the advance resistance of middle part chute, prevent middle part from slipping
Slot the more is walked the more deep to underground；When float coal is less, adjust hydraulic cylinder shrink, tilt down ramp plate, prevent middle part chute to
Upper " drift " is detached from ground, is sprayed water during shoveling coal from nozzle to working face, reduces coal dust and generates.
Certainly, above content is only the preferred embodiment of the utility model, be should not be construed as limiting practical new to this
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With all the changes and improvements etc. made in novel essential scope, the patent covering scope of the utility model should all be belonged to
It is interior.
