The delivery outlet of oil pump 401 is mutually connected with two ways with the roller cavity 415 outside pressure roller shaft 204 respectively：
First, referring to Figure 16-18, Figure 22,23, the spindle through-hole 406 by lower end to upper end is opened up on main shaft 6, connect
The oil pipe 404 of the delivery outlet of oil pump 401 is communicated by But rotary joint 405 with the lower mouth of spindle through-hole 406, spindle through-hole 406
It is suitable for reading to be communicated by five logical 419, oil pipe 418, fuel feed hole 416 with roller cavity 415.But rotary joint 405 and main shaft lower end are into can
Rotate connection；And on main-shaft axis.This structure, makes granulator compact conformation, it is to avoid with external device（Such as the outer feeding of machine
Mechanism）Interference, improves safety in utilization, but the processing cost of spindle through-hole is higher, a set of sealing dress of increase in the lower end of main shaft 6
Put.
Second, referring to Figure 19-21, the oil pipe for connecting the delivery outlet of oil pump 401 passes through But rotary joint 405, five logical 419, oil
Pipe 418, fuel feed hole 416 are communicated with roller cavity 415.Five logical 419 are fixed on above main shaft roller seat cover plate, But rotary joint 405
It is connected between five logical 419 by communicating pipe.But rotary joint 405 can rotate relative to communicating pipe.But rotary joint 405,
Five logical 419, it is respectively positioned on the axis of main shaft communicating pipe.This structure, reduces processing cost, reduces a set of sealing device, but meeting
With external device（Such as the outer feeding mechanism of machine）Interference, reduces safety in utilization, and space-consuming is significantly increased.
Weigh the two ways that the above-mentioned delivery outlet of oil pump 401 is communicated with the roller cavity 415 outside pressure roller shaft 204 respectively, it is best
Using the first higher scheme of security.
When lubricating system 4 works, flow through path of the lubricating oil in oil circuit is：
The lubricating oil that oil pump 401 pressurizes, it is suitable for reading to the hole of main shaft 6 through oil pipe 418, But rotary joint 405, by five logical 419 warps
Oil pipe is branched to after roller cavity 415 lubricates and cool to taper roller bearing 206, through built on stilts chamber 207 to axle cavity 407 to ball axle
Hold after lubricating and cooling, flow to fuel tank 420.
The beneficial effect of this technology is：
Granulation mechanism is provided with four groups of pressure rollers, relative to the granulator of two pressure rollers of prior art, hence it is evident that improve work
Make efficiency.The granulator of this patent, when main motor is 90kw motors, obtained bar is 2.5 tons per hour, is raw per hour
Produce the common granulator of 1.5-1.8 tons of bar（Its power of motor is 90kw）1.5 times or so, significantly improve production efficiency,
And reliable operation.
Lubricating system can also considerably increase radiating using casing as fuel tank to sufficient lubrications such as the transmissions in casing
Area, to lubricating oil effective temperature-reducing；, can be cold to each rotational components sufficient lubrication of granulator by the way of interior circulation lubricates
But.
Using centrifugation feeding mechanism 3, reduce probability of the solid accumulation on roller frame 201, be easy to material feeding wedge shape
Extrusion chamber；By material uniform stirring, make granulator smooth running.
Foregoing ring die pelleter, cutting knife is arranged on roller seat cover plate, and cutting knife is the offer by main motor
Charge bar of the power cut from granulation hole extrusion.In the case of so, granulator operating efficiency is not high.Therefore, having made following improvement, join
See Figure 26-31, the lower end of up-small and down-big taper feed hopper 81 is fixed on ring mould, the lower end peripheral of feed hopper, which has, to be extended to
The shrouding 82 of back-up ring, cutter driving motor 83 is fixed on shrouding.4 to 6 small axle 84, small axle are fixed with the inner circumferential of back-up ring 213
Upper setting spring bearing 85, spring bearing axis is radially extended along ring mould.Baffle ring 86 is arranged at the top between back-up ring and ring mould, gear
Ring 86 is arranged on back-up ring by spring bearing around what ring mold shaft line was rotated；Gear ring 87 is connected on baffle ring top；Engaged with gear ring
Little gear 88 be arranged on the output shaft of cutter driving motor.Gear ring and little gear are located between shrouding and baffle ring.Parallel to
The four of ring mold shaft line extension are used to cutting knife 89 cut off the charge bar extruded from granulation hole, and four pass through transition the top of cutting knife 89
Plate 91 is connected to baffle ring bottom, and the bottom connection of cutting knife 89 is used for the pusher for the charge bar that promotion is cut off along what ring mould was radially extended
Plate 90.By this improved granulator, when main motor is that 90kw motors, cutter driving motor are 1.5kw, it is made per hour
Bar be 2.8 tons, be per hour produce 1.5-1.8 tons of bar common granulator（Its power of motor is 90kw）1.6 times
Left and right.Scraping wings is rotated around ring mold shaft line together with cutting knife, and the charge bar of cut-out is shifted onto discharge outlet, is easy to discharging.Pass through
Broach hopper, is easy to material to be sent into from outside between the ring mould and pressure roller of granulator or on roller seat.Little gear and gear ring
In relatively closed space between shrouding and back-up ring, prevent foreign matter from entering, it is ensured that little gear and the normal work of gear ring
Make.
