It closes, makes chip removal storehouse 9 for air-tight state, ensure that the iron filings remained in chip removal storehouse 9 will not leak out.
A kind of rail milling vehicle crumb loading storehouse in this programme includes two motion flows, crumb loading process and chip removal process.
Crumb loading process：When rail milling vehicle carries out milling effect, start wind turbine 1, wind turbine 1 has air draught effect, from close
Air draught forms subnormal ambient in the storage bits storehouse 3 closed.Storage bits storehouse door control mechanism 8 is in the shape for closing storage bits storehouse door 7 at this time
State ensure that the seal in storage bits storehouse 3, to have the function that be formed stable subnormal ambient.2 meeting of pressure sensor after negative regulation
The pressure for monitoring subnormal ambient, can effectively collect the iron filings of milling after reaching the pressure needed for crumb loading.Pass through collection
The iron filings being collected into can be transmitted directly to store in storage bits storehouse 3 by bits pipeline 6.Since storage bits storehouse door 7 divides crumb loading storehouse
For storage bits storehouse 3 and the different functional warehouse in about 9 two, chip removal storehouse, the iron filings being collected into can be stored directly in storage bits storehouse, will not
It stores in chip removal storehouse 9, avoids iron filings and be deposited on spiral chip cleaner 12, extend the service life of spiral chip cleaner 12,
When iron filings reach the maximum allowable amount of storage in storage bits storehouse 3, level transducer 4 can be triggered, prompts storage bits storehouse 3 to expire, wind turbine 1 will
It is stopped, terminates crumb loading process, while the milling operation of rail milling vehicle need to be stopped, needing to carry out chip removal to appointed place at this time
Process.
Chip removal process：When rail milling vehicle is to when giving directions place to carry out chip removal, the contraction of chip removal storehouse door cylinder 10 first is beaten
Begin to rehearse bits storehouse door 11, then starts chip removal motor 13, drives spiral chip cleaner 12 to rotate, chip removal is ready at this time.Work as storage
When considering the opening storage bits storehouse door 7 of storehouse door control mechanism 8 to be worth doing, the stroke of cylinder is controlled by travel switch, and then control and store up bits storehouse
The opening size of door 7.It is entered in chip removal storehouse 9 with the slow flow of stabilization so that iron filings are considered to be worth doing from storage in storehouse 3, such iron filings warp
The buffering for crossing chip removal storehouse 9 is fallen in the spiral chip cleaner 12 rotated with a stable speed, in spiral chip cleaner 12
Under effect, what iron filings were stablized is discharged to outside storehouse.Iron filings are discharged to storehouse from storage bits storehouse 3 to chip removal storehouse 9, then by spiral chip cleaner 12
Outside, it forms one and stablizes smooth chip removal process.After chip removal, storage bits storehouse door control mechanism 8 closes storage bits Cang Cang
Door 7 ensures the seal in storage bits storehouse 3.Stop chip removal motor 13, terminate chip removal operation, chip removal storehouse door cylinder 10, which stretches out, closes
Chip removal storehouse door 11 ensures that the iron filings remained in chip removal storehouse 9 will not leak out.Crumb loading storehouse chip removal process finishes at this time, and can be into
Row crumb loading process.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, can also make several improvements and retouch, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
It is the utility model perfect in shape and function, simple operation, simple in structure, safe and reliable, in such a way that function divides storehouse, it will store up
Bits are separated with chip removal, and crumb loading storehouse is divided into storage bits storehouse and chip removal storehouse two parts up and down, and the iron filings being collected into are introduced into storage bits storehouse and deposit
Storage, detaches with chip removal storehouse.
When not needing chip removal, iron filings are stored in storage bits storehouse, reduce the pressure load in chip removal storehouse, extend using the longevity
Life.
Open storage bits door when needing chip removal, while controllable door aperture makes what iron filings slowly stablized to enter chip removal
Storehouse ensures the fluency of chip removal.
