Abstract
The utility model discloses a kind of development machine tunneling boring dust cover, it comprises the collapsible cover body being arranged on hydraulically extensible oil cylinder on development machine and section and excavated section shape and adapting, the external part of hydraulically extensible oil cylinder stretches to the keystone of development end, external part front end and collapsible cover body front end link together, the rear end fixed cover of collapsible cover body is in the inlet scoop of dedusting fan, thus collapsible cover body can be made to stretch along with the flexible of hydraulically extensible oil cylinder, heading machine cutting head can be made again to be all in operation in cover body; Hydraulically extensible oil cylinder is that power realizes expanding-contracting action with tunneling machine hydraulic system.The utility model structure is simple, and dust removing effects improves, and greatly reduces dust concentration, improves on-the-spot worker's operating environment, can move with development machine and move without secondary, realize HYDRAULIC CONTROL SYSTEM, easy to operate.
Description
Technical field
The utility model relates to the development machine of colliery digging laneway.
Background technology
Current colliery digging laneway, generally apply development machine, a large amount of dust of generation continued in tunneling machine cutting process, although development machine is all provided with dedusting fan, but the air draught of dedusting fan is young, can not follow development machine work plane in time, be difficult to play the inlet scoop effect effectively reducing dedusting fan, dedusting fan is just as ornaments, can not play dust suction effect, make that operating environment is severe, the development machine driver visual field is poor, generation high risks is breathed to worker, affects worker health.
Summary of the invention
In order to solve dust removal problem in tunneling machine cutting process, utility model designs a kind of development machine tunneling boring dust cover.
A kind of development machine tunneling boring dust cover, it is characterized in that, it comprises the collapsible cover body being arranged on hydraulically extensible oil cylinder on development machine and section and excavated section shape and adapting, the external part of hydraulically extensible oil cylinder stretches to the keystone of development end, external part front end and collapsible cover body front end link together, the rear end fixed cover of collapsible cover body is in the inlet scoop of dedusting fan, thus collapsible cover body can be made to stretch along with the flexible of hydraulically extensible oil cylinder, heading machine cutting head can be made again to be all in operation in cover body; Hydraulically extensible oil cylinder is that power realizes expanding-contracting action with tunneling machine hydraulic system, and when hydraulically extensible oil cylinder stretches out, Foldable formula cover body launches forward to cover in development end, makes dust be inhaled into dedusting fan in cover body, no longer spreads to surrounding.
Good effect of the present utility model is: one is have folder function, and the used time is not deposited in above development machine and do not take up space, its device strong adaptability, and two is that tunneling boring dust exhaust apparatus is placed on development machine and can moves with development machine and move without secondary with it; Three is realize HYDRAULIC CONTROL SYSTEM, easy to operate; Four visuals field being improved fully mechanized workface operating environment and development machine driver, workmanship increases, and eventually passes and repeatedly debugs, and obtains successfully, and the operation of development machine hydraulic pressure tunneling boring negative-pressure dust suction hood, mobile effect all reach best.
In a word, the utility model structure is simple, and dust removing effects improves, and greatly reduces dust concentration, improves on-the-spot worker's operating environment, can move with development machine and move without secondary, realize HYDRAULIC CONTROL SYSTEM, easy to operate.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data, 1-development machine, the collapsible cover body of 2-, 3-support bar, 4-inflaming retarding fabric cloth, 5-dedusting fan, 6-hydraulically extensible oil cylinder, 7-development end, 8-heading machine cutting head.
Detailed description of the invention
Development machine tunneling boring dust cover as shown in Figure 1, it is characterized in that, it comprises the collapsible cover body 2 with fore-aft fold function be arranged on development machine 1, collapsible cover body 2 forms by inflaming retarding fabric cloth 4 is folding, crease is provided with support bar 3, when collapsible cover body 2 launches, section and excavated section shape adapt, development machine 1 is also provided with hydraulically extensible oil cylinder 6, hydraulically extensible oil cylinder 6 external part front end and collapsible cover body 2 front end link together, the rear end fixed cover of collapsible cover body 2 is in the inlet scoop of dedusting fan 5, thus collapsible cover body 2 can be made to stretch along with the flexible of hydraulically extensible oil cylinder 6, heading machine cutting head 8 can be made again to be all in operation in cover body, hydraulically extensible oil 6 is that power realizes expanding-contracting action with tunneling machine hydraulic system, when hydraulically extensible oil cylinder 6 stretches out, Foldable formula cover body 2 launches forward to cover in development end 7, dust is made to be inhaled into dedusting fan 5 in cover body, no longer spread to surrounding.
Claims (1)
