Fig. 2 is the part vertical view according to the drum-type grader of Fig. 1, wherein has the machine casing end of independent expression.
Fig. 3 is the amplification view of drum-type grader along Fig. 2 center line III-III, and wherein the latter half is represented separately.
Fig. 4 is used to screen the cutaway view that bulging cleaning plant is represented with vast scale more along Fig. 1 center line IV-IV.
The specific embodiment
The drum-type grader mainly can be divided into four members: machine casing, screening drum, cleaning plant and driving mechanism.
The machine casing 1 that all sides are all sealed is by means of two supporting part 2 and 3 and be placed on the ground, on antetheca, has material inlet 4, have on the rear wall be used for classification after the outlet 5 of material, have two outlet hoppers 6 and 7 that are used for grading waste at its downside.The loam cake 8 of machine casing uses bolting, and two longitudinal side walls are fixed by means of shared quick fastener, so that installation or removal easily also can be observed screening drum and its cleaning plant again.Material inlet 4 is fixed on the antetheca 9 of machine casing 1 tightly, and outlet 5 is fixed on another rear wall 10 with the same manner.
Sharf 19 is such conveyers, and promptly it transports the material after the classification by screening drum 11 by means of its blade 20.Counter flange 21 and sieve seal 16 all are the tension force makers, are used for driving ring 14 and 15 is fixed on sieve 12.
Owing to used bearing arrangement, the screening drum can be pulled down apace.
Cleaning plant be have knocker 31 knock the axle 30.Brush shape knocker 31 is made by nylon, and they are fixed on the axle 30 by this way, and promptly the time spent can be changed again when wearing and tearing.Knock axle 30 and be placed on two anti-friction bearings 32, anti-friction bearing is caught by U type guide 33 and is slided, and U type guide is fixed on antetheca 9 and the rear wall 10 by means of screw 36.At the anti-friction bearing 32 that plays the guide effect with radially be fixed under guide 33 on the major axis of screening drum helps, knock axle 30 and have an axis of pitch and can change its position with respect to screening drum 11.Therefore brush the shape cleaning plant and can freely be positioned on the screening drum, and each screening drum all has such cleaning plant.Knocking on the axle 30, two driven rollers of being made by synthetic material 34 and 35 are installed, wherein driven roller 34 has cylindrical rotating surface and is connected (Fig. 1,2 and 3) by friction with the driving ring 14 of screening drum 11, driven roller 35 has wedge shape rotating surface and will self be engaged in the teeth groove 29 of driving ring 15 of screening drum 11, and it is by friction be connected with teeth groove 29 (Fig. 1).
In order to drive screening drum 11 and to knock axle 30, be provided with gear motor 37, it is fixed on the loam cake 8 of machine casing 1, and has the gear 38 that is installed on its driven shaft.Odontoid belt 39 couples together gear 38 and gear 40, and gear 40 is installed on the axle 26 of driven roller 24 and 25.The torque that is produced by gear motor 37 sends driven roller 24 and 25 to by gear mesh 38,40 and odontoid belt 39 and via axle 26.These two driven rollers 24 and 25 driving rings of determining via them by friction 14 and 15 drive screening drum 11.But driving ring 14 and 15 also is connected on driven roller 34 and 35, so driving torque not merely sends screening drum 11 to, knocks axle 30 so that its motion but also send to simultaneously.
Enter the cereal of drum-type grader by material inlet 4, corn for example is from the inside of surface wall side inflow screening drum 11.With screening drum 11 rotating blades 12 cereal is sunk, because they tilt to place, it in axial direction promotes cereal forward on sieve.Therefore bigger iblet is transported by sieve by this way, flows on its terminal counter flange 21, enters outlet 5 downwards as the material after the classification, and enters thus in tube connector or container or the gunnysack.Less iblet and broken corn grain and pollutant downwards enter outlet 6 and 7 by through hole 13 as grading waste in sieve 12, they enter in gunnysack or other containers by outlet opening thus.
In the progressive operation process; knock axle 30 running continuously; its nylon bruss 31 beats on the rotation sieve 12 of screening drum 11, thereby the iblet or the broken grain that get lodged in the through hole 13 just can be pushed out, or they pass through through hole downwards owing to beat the vibration of caused sieve 12.Therefore sieve 12 can constantly be cleared up, and promptly its through hole 13 can keep unimpeded.
On the one hand, owing to the continuous use of drum-type grader makes the rotating surface of driving ring 14 and 15 that wearing and tearing and damaged take place inevitably, on the other hand, driven roller 24,25,34 and 36 and 22 pairs of backing rolls screening drum 11 and the driving mechanism that knocks axle 30 do not have any influence, this is because under the gravity effect, screening drum 11 and two driving ring 14 and 15 also can be pressed in all the time driven roller 24 and 25 and backing roll 22 on, can be guaranteed thereby necessary power is frictional force always.To knocking axle 30 too, therefore it moves with respect to screening drum 11 in guide 33, even between driving ring 14,15 and the driven roller 34,35 wearing and tearing have taken place and damage, because gravitate, it still can sink, even necessary herein friction connection also can be kept.
If screening drum 11 or knock axle and 30 have to for some reason with its dismounting, for example screen different material if desired and have to sieve 12 is replaced by other suitable classification through hole, if or knocker 31 and knock axle 30 and ground away and have to install new knocker, at this moment machine casing 1 longitudinal side wall can be removed at an easy rate by above-mentioned quick fastener.So just can be at an easy rate near knocking axle 30 and screening drum 11.Knocking at this moment axle 30 just can be by pulling out it and corresponding perpendicular to axial direction moving and taking-up from machine casing 1 from U type guide 33.When knocking after axle is removed screening drum 11 even also can equally easily be removed.This be by will screen that drum 11 draws on driven roller 24,25 and the backing roll 22 lightly and by produce therefrom axially and moving of X direction realize.
The drum-type grader is designed by this way, and promptly multipotency has three machines can be by the modular construction of shell 1 to be arranged by self stack.
As follows by the resulting progress of the present invention: the simplest and easy, the technical pattern that can obtaining of being adopted drives function reliably and knock the clearing function of axle safety can obtain best cost performance, knock the dismounting of axle and screening drum and install simple and save time, even these operations just can be finished by operating personnel.
