Abstract
The utility model discloses a dust blocking device of a heading machine for a single air duct compressed air heading roadway. The dust blocking device comprises a drop device, a permanent magnet jack, air screen curtains and a hook, wherein the air screen curtains are arranged beside a driver of the heading machine and behind the driver of the heading machine, the air screen curtain behind the driver is provided with a groove corresponding to a compressor air cylinder, the hook is arranged at the upper part of the air screen curtain, the air screen curtain is hung on an anchor net or anchor rod at the top wall of the heading roadway, the permanent magnet jack is arranged at the middle part of the air screen curtain, the air screen curtain is arranged on a heading machine housing, and the drop device is arranged at the lower part of the air screen curtain and placed on the ground of the heading roadway so that the air screen curtain keeps in contact with a floor to completely block dust. The dust blocking device has a simple structure, is convenient to install, and is capable of effectively blocking dust passing through the driver position of the heading machine so that the health hazard to the driver is reduced.
Description
Technical field
The utility model relates to a kind of type dust arrester, specifically a kind of development machine type dust arrester of pressing the wind digging laneway for single air duct.
Background technology
Development machine is be used to the machine of digging straight underground passage.Development machine is divided into open type development machine and shield formula development machine.Price is generally at more than one hundred million yuans.Mainly formed by walking mechanism, operating mechanism, shipment activity and transferring mechanism.Along with walking mechanism is pushed ahead, the continuous fractured rock of the cutting head in the operating mechanism, and detritus transported.Have safety, efficiently with become the advantages such as the lane quality is good.
In the digging laneway of colliery, dust is to development machine driver's healthy harm.The digging laneway in colliery much adopts the forced draft type of single air duct at present, and it presses the air duct outlet to be positioned at top, development machine driver's seat.So that produce eddy current at the anterior wind field of heading end, cause dust to pass through from the side development machine driver's position with the back secondary, it is worked the mischief.In the reality, on the development machine not under single air duct forced ventilation mode, effectively reduce the dust-break method by development machine driver position Dust Capacity.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of development machine type dust arrester for single air duct pressure wind digging laneway, and is simple in structure, easy for installation, can effectively stop the dust by development machine driver position, reduce the health hazard to the driver.
To achieve these goals, the technical solution adopted in the utility model is: a kind of development machine type dust arrester of pressing the wind digging laneway for single air duct, comprise born device, permanent magnetic lifter, screen and hook, screen is arranged on development machine driver position side and rear side, the rear side screen has the groove corresponding with pressing air duct, hook is arranged on screen top, screen is hung on the anchor net or anchor pole of digging laneway roof, permanent magnetic lifter is arranged on the screen middle part, screen is installed on the development machine shell, and born device is arranged on the screen bottom, is placed on the digging laneway ground, keep screen to contact with the floor, keep dust-break complete.
Further, screen materials'use polyethylene is material.
The beneficial effects of the utility model are: by at development machine driver position side and rear side screen being set, top hangs on the anchor net or anchor pole of digging laneway roof by hook, the middle part is fixed on the development machine shell by permanent magnetic lifter, the bottom is arranged on the digging laneway ground by born device, thereby guaranteed the sealing of the upper bottom of screen, so that in the development machine tunneling process, kept further having reduced the health hazard to the development machine driver for the stopping fully of the dust of coming from the migration of side, driver position and back.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, development machine, 2, digging laneway, 3, born device, 4, permanent magnetic lifter, 5, screen, 6, hook, 7, press air duct.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of development machine type dust arrester of pressing the wind digging laneway for single air duct, comprise born device 3, permanent magnetic lifter 4, screen 5 and hook 6, screen 5 is arranged on development machine 1 driver position side and rear side, rear side screen 5 has the groove corresponding with pressing air duct 7, hook 6 is arranged on screen 5 tops, screen 5 is hung on the anchor net or anchor pole of digging laneway 2 roofs, permanent magnetic lifter 4 is arranged on screen 5 middle parts, screen 5 is installed on development machine 1 shell, and born device 3 is arranged on the screen bottom, is placed on digging laneway 2 ground, keep screen 5 to contact with the floor, keep dust-break complete.
In the utility model, preferred, described screen 5 materials'use polyethylene are material, and toughness and sealing are better, can further improve the dust-break effect of device.
In conjunction with top described, by at development machine 1 driver position side and rear side screen 5 being set, top hangs on the anchor net or anchor pole of digging laneway 2 roofs by linking up with 6, the middle part is fixed on development machine 1 shell by permanent magnetic lifter 4, the bottom is arranged on the digging laneway ground by born device 3, thereby guaranteed the sealing of the upper bottom of screen 5, in development machine 1 traveling process, kept for the stopping fully of the dust of coming from the migration of side, driver position and back, thereby further reduced the health hazard to development machine 1 driver.
