Description
Technical field
It is the present invention relates to a kind of device that can remove railway sand, in particular to a kind of by the comprehensive clear sand of rail, and will
Sand encapsulation avoids the sand by the device of the secondary burial of railway.
Background technique
With the fast development of China Railway, more and more rail tracks are routed to northwest such as Qinghai, Xinjiang
Etc. the area for closing on desert, local vegetation sparse, dust storm is more.Since the Lan-xing Railway, Qinghai-Tibet Railway are open to traffic, sandstorm is just
As the important hidden danger of train safe operation, withdrawal of train is caused to be made to people's trip and railway transportation because dust storm buries railway
At huge economic loss.Currently, existing clear husky equipment can remove substantially between on the inside of two rails and its certain model in outside
The sand enclosed, but the grains of sand retained on rail not can effectively clear.When train passes through, these grains of sand will gnaw rail,
It causes rail surface pit occur, causes a hidden trouble to the safe operation of train；Sand is discharged by the clear husky device that in addition, there will be
Rail both sides is easy to bury rail again when blowing, and there are secondary rails to be buried risk.Therefore, the present invention is a kind of energy
Sand above comprehensive removing railway sand, especially rail, and the device that sand is packaged.
Summary of the invention
It the present invention provides a kind of comprehensive removing railway sand and encapsulates the device of sand, is removing on the inside of two rails it
Between and its outside a certain range sand on the basis of, secondary cleaning is carried out to the sand above rail, is realized above rail and two
It removes sand comprehensively side.Meanwhile the sand of cleaning can be subjected to automatic packaging, it delivers by railway, prevents the sand by railway two
Secondary burial.The sandbag of encapsulation can be used for combating typhoon, and the places such as flood control have certain use value and economic value.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of comprehensive removing railway sand and the device for encapsulating sand, including scrape husky system, sand collecting system, disc type litter cleaning machine
