As shown in figure 28, have with identical external diameter spiral-shaped along axis direction as the helical spring 47 of dedusting vibration section.The about 26mm of the external diameter of helical spring 47.As wire rod, it has used the piano wire rod of line footpath as 1mm.Helical spring 47 has been implemented antirust electroplating processes.Also can adopt the wire rod of stainless steel wire or synthetic resin.
Shown in figure 32, helical spring 47 directly remains on the periphery of cartridge 46 within it with the clearance G of about 1mm between the periphery of side and maintenance rib 60.The gap of cartridge 46 and helical spring 47 is keeping rib 60 place in addition to become bigger.
In addition, helical spring 47 has two rotation prevention portions 67 at two ends.The rotation prevention portion 67 that is arranged on retainer ring 66 two ends is by the formation that curves inwardly, thereby makes the length direction of the two ends of retainer ring 66 along cartridge 46.A rotation prevention portion 67 becomes terminal, and another rotation prevention portion 6 links to each other with helical spring 47.As shown in figure 25, two rotation prevention portions 67 are arranged to be engaged between the end of circular-arc engaging protrusion 61 of adjacency.Helical spring 47 utilizes two rotation prevention portion 67 splines, remains on the cartridge 46.Be held and the helical spring 47 of spline,, be fixed on reliably on the cartridge 46 and can not break away from by the installation of end ring 48.Therefore, carry out dedusting when rotation,, thereby make dedusting everything goes well with your work and carry out because helical spring can not come off with cartridge 46 yet at dedusting rotary body 44.
Dedusting rotary body 44 has slave end rotary body bolster 80 and driving side bolster 81.Below with reference to Figure 14, Figure 30-Figure 32, the assembling of the dedusting rotary body that comprises this slave end rotary body bolster 80 and driving side bolster 81 is described.
The cartridge 46 of dedusting rotary body 44 with slave end rotary body bolster 80 and 81 folding and unfoldings of driving side bolster in inner space 49.As (1) of Figure 14, shown in Figure 30, the left half side part of inner space 49 has 4 smooth standstill faces 82; As Figure 14 (1), shown in Figure 31, remaining right half side part forms the circular space of non-spline.Left end at cartridge 46 is provided with the anticreep bead 83 of diameter less than the internal diameter of inner space 49.
Figure 14 (1) is the single part of cartridge 46.Figure 14 (2) expression cartridge 46 has been installed the state of helical spring 47.Figure 14 (3) expression is with pack into the state of inner space 49 of cartridge 46 of slave end rotary body bolster 80.Slave end rotary body bolster 80 inserts from the right side of cartridge 46, keeps it not come off by the anticreep bead.
Slave end rotary body bolster 80 has standard shaft 84, median plate 85, and end plate 86, splinter bar 87, the slave end aixs cylinder plays 88.The periphery of median plate 85 and end plate 86 is owing to make the identical shape in inner space with 82 places, standstill face, thereby makes 80 pairs of cartridge 46 splines of slave end rotary body bolster.The slave end aixs cylinder plays 88 states that are in the left end that protrudes in cartridge 46.
Figure 14 (4) expression is installed in energizing spring 89 state on the splinter bar 87 of slave end rotary body bolster 80.As Figure 14 (5) shown in, intermediate 100 embedded and be installed in splinter bar 87 on thereafter.Though it is intermediate 100 is entrenched on the splinter bar with being free to slide along its length, restrained and can not rotate in direction of rotation.Shown in figure 32, because the cross section of splinter bar is the H shape, the hole on the embedding splinter bar of intermediate 100 also is the H shape, thereby can not rotate.
Figure 14 (6) is illustrated in the state that driving side bolster 81 has been installed on the cartridge 46.Driving side bolster 81 can rotate freely, and can be installed in the inner space 49 of cartridge 46 with being free to slide vertically.The outer end of driving side bolster 81 has drive-side shaft projection 101.
Driving side bolster 81 has embedded hole in an opposite side of drive-side shaft projection 101, can rotate freely in this embedded hole, and vertically intermediate 100 can be installed with being free to slide.Be provided with driving pawl in the embedded hole inboard that is positioned at drive-side shaft projection 101 opposite sides.Intermediate 100 has driven ratchet at the end face of the inboard that embeds embedded hole.The engagement of driving pawl and driven ratchet applies power by energizing spring 89.
The rotation of driving side bolster 81 passes to slave end rotary body bolster 80 by driving pawl and driven ratchet.The transmission of rotation is only carried out in the rotation of a direction of driving side bolster 81, and the rotation of not transmitting another direction.The rotation of a direction is meshing with each other by driving pawl and driven ratchet and is rotated transmission.For counter-rotating, because driving pawl and driven ratchet do not mesh, the intermediate 100 of driven ratchet moves energizing spring 89 compressions, and the rotation transmission can't be carried out.
So, the dedusting rotary body of assembling is installed on the dust arrester supporting frame.Installation to the dedusting rotary body describes below.
Figure 15 represents to install the dust arrester supporting frame 43 before the dedusting rotary body 44.
Dust arrester supporting frame 43 has the dust removing body that dedusting rotary body 44 is installed in the top of air vent 45 portion 102 is set.But the dust removing body with folding and unfolding dust arrester supporting frame 43 sizes be provided with portion 102 by wall divide forms about, about reach the back, make the structure that does not have aeration.In being provided with the left side wall of portion 102, dust removing body is provided with the bearing block 104 of slave end dead eye 103.The sidewall 105 that dust removing body is provided with the right side of portion 102 has inboard bearing hole 106.This inboard bearing hole 106 is to lead to outside hole; Dust removing body is provided with portion 102 and has the dedusting rotary body rear support portion 107 of extending about two overleaf.
Figure 16 is illustrated in dedusting rotary body 44 places the state that dust removing body is provided with portion 102 has been installed.
Slave end rotary body bolster 80 and driving side bolster 81 are pushed cartridge 46 inboards.Since the slave end aixs cylinder rise 88 and drive-side shaft projection 101 enter in cartridge 46 two ends, thereby the 44 easy folding and unfoldings of dedusting rotary body are provided with in the portion 102 at dust removing body.And, aim at slave end dead eye 103 by making the slave end aixs cylinder play 88, and, expose and be embedded in the slave end dead eye 103 thereby make the slave end aixs cylinder play 88 by energizing spring 89 pushings.Equally, by drive-side shaft projection 101 is aimed at inboard bearing hole 106, drive-side shaft projection 101 also by energizing spring 89 pushings, is fitted in the inboard bearing hole 106.(as shown in figure 17)
As Figure 17, shown in Figure 19, the setting of drive-side shaft projection 101 makes it protrude in side wall portion 105 outside sides.Axle envelope parts 108 are installed at drive-side shaft projection 101 places.Axle envelope parts 108 have the function of inhibition air through the clearance leakage of inboard bearing hole 106 and drive-side shaft projection 101.
Axle sealing 108 is made by rubber or soft plastic material, roughly is to have a portion 120, the shape of the L word of flange 121.Axle envelope parts 108 have the sealing projection 122 of ring-type week in tube portion 120.In addition at the locator protrusions that has ring-type week 123 of the tube portion 120 of the root that is positioned at flange 121.The cross sectional shape semicircular in shape of sealing projection 122.The flange 121 of axle envelope parts 108 is arranged to side wall portion 105 outside sliding-contacts and is kept sealing function.
Drive-side shaft projection 101 has annular seal groove and ring-type locating slot position in periphery.Seal groove is arranged on the front end near drive-side shaft projection 101, and locating slot is arranged near drive-side shaft projection 101 roots.The axle envelope parts 108 that are installed in drive-side shaft projection 101 places make sealing projection 122 chimeric with seal groove, make locator protrusions 123 and locating slot chimeric.With the chimeric locator protrusions 123 of locating slot except positioning function is arranged, also have the sealing function same with sealing projection 122.
The travelling gear 124 of rotary transmission part as shown in figure 18, is installed in the end of drive-side shaft projection 101.Travelling gear 124 usefulness screws are fixed.
As Figure 20, shown in Figure 21, be installed in dedusting be provided with in the portion 102 dedusting rotary body 44 with dorsad the state of dedusting rotary body rear support portion 107 install.Two dedusting rotary body rear support portions 107 are arranged to extend along the length direction of dedusting rotary body 44.The interval G (2-3mm) of the periphery of helical spring 47 and dedusting rotary body rear support portion 107 is arranged to same widths along its length.
The dismounting of dedusting rotary body 44 is by inserting with the patchhole 125 from the bottom of the bearing block 104 that is arranged on Figure 15-shown in Figure 180 such as screwdriver, slave end rotary body bolster 80 is shifted onto the inboard of cartridge 46, like this, break away from slave end dead eye 103 because the slave end aixs cylinder plays 88, thereby be easy to carry out.To leak in order preventing to suck, usually patchhole 125 to be added upper cover.In addition, if the dismounting of dedusting rotary body 44 also can be without patchhole 125 when adopting other method.
With as mentioned above the assembling after dust arrester unit 26 as Fig. 9, Figure 10, Figure 12, shown in Figure 22, be arranged between electric blowing machine 24 and the collecting unit of dust 5.
Why can realize the engagement of this assembling function admirable, be because adopted the axis of rotation that engagement is configured in travelling gear 124 to be positioned at the structure of the axis of rotation top position of driven wheel 42.
In addition, because with the axis of rotation configured in parallel of axis of rotation and the driven wheel 42 of travelling gear 124, and two gears are all made spur gear, thereby two outer peripheral gears butt joints are meshed.Even how spool 41 vibrates in the axis of rotation direction, two gear meshing can both be kept stable engagement, can carry out the dedusting rotation of dedusting rotary body 44 reliably.
To the rotating actuator of dedusting rotary body 44 owing to have only the driven wheel 42 of spool 41 and 124 two parts of travelling gear of dedusting rotary body 44, thereby have have when can realize compact structure simple in structure, assembling is rotated the inferior advantage of transmission loss easily.
Also have, rotating actuator can utilize bevel gear, various gears such as helical gear.
Dedusting to dust-collecting filter describes below.
As shown in figure 13, the periphery of helical spring 47 is arranged to enter between the ripple of dust-collecting filter 8.Enter the degree of depth and be about 1mm.Along with the rotation of helical spring 47, the crest of undulatory dust-collecting filter 8 is vibrated to carry out dedusting.
Because the transverse width of dust-collecting filter 8 is about 100mm, the length desire of helical spring 47 is 80mm, thereby the whole transverse width of almost crossing over dust-collecting filter 8 carries out dedusting.
Dust-collecting filter 8 is owing to be arranged to vertically advance between ripple, and dedusting rotary body 44 is arranged on the top position of dust-collecting filter 8, thereby accumulates in the below of dust-collecting filter 8 by the shaken dust that falls of dust-collecting filter.
The dedusting of dust-collecting filter 8 is undertaken by the rotation of dedusting rotary body 44.The rotation of dedusting rotary body 44 is only carried out when pulling out the electric wire 40 of bobbin 25.When electric wire 40 rollbacks,, then be just to increase because bear the load of the disc spring of rollback electric wire 40 if dedusting rotary body 44 is turned round.So, if increase disc spring intensity, even when the rollback electric wire, also can carry out dedusting.
In addition, by the electric wire 40 of pulling out bobbin 25, the rotation of spool 41 is delivered to travelling gear 124 through rotating actuator shown in Figure 23 (driven wheel 42 of spool 41 and the travelling gear 124 of dedusting rotary body 44).Driving side bolster 81 is passed through in the rotation of travelling gear 124, intermediate 100, and slave end rotary body bolster 80 is delivered to cartridge 46.Like this, make 44 rotations of dedusting rotary body.
In the rollback of electric wire 40, because spool 41 is counter-rotating, thereby rotation is transmitted and is interrupted between the driven ratchet of the driving pawl of driving side bolster 81 and intermediate 100, and then rotation can not be delivered to dedusting rotary body 44.
Figure 33-Figure 35 represents to use the dedusting pattern of the dust-collecting filter 8 of helical spring 47.
Figure 33 is the preceding state of helical spring 47 rotations of expression dedusting rotary body 44.As shown in figure 34, be accompanied by the rotation of helical spring 47, the crest of dust-collecting filter 8 is pushed left.When the crest of dust-collecting filter 8 was crooked left, strain also took place left in helical spring 47, and helical spring 47 constantly moves on the top of crest, and is crooked more as shown in figure 35, and distortion is increased.And in case cross crest, helical spring 47 is by ejecting from laterally that a left side is adjacent crest, thereby makes dust-collecting filter 8 vibrations, will shake attached to the dust on the surface (dust is caught face) of dust-collecting filter 8.In addition, in case cross crest,, dust and filter plane are peeled off because original position is arrived in the deformation-recovery that is accumulated on the dust-collecting filter 8, thereby vibrates dust-collecting filter 8 intensely.The dedusting of this dust-collecting filter 8 is carried out in wider scope along the scope of the length direction of dedusting rotary body 44, by electric wire 40 is pulled out once, because more than helical spring 47 rotations 10 circles, thereby can carry out dedusting repeatedly, obtain higher dust removal performance.
In addition, from the crest dedusting of real oscillation crosswise dust-collecting filter 8, owing to have no equally to carry out along the length direction scope of dedusting rotary body 44, thereby be not easy to produce except that dust spot with departing from.Also have, utilize the dedusting of helical spring 47 rotations and since dust-collecting filter 8 all touch helical spring 47 everywhere, thereby can not make load produce big change, the operation of pulling out of the electric wire 40 that is easy to advance because of the difference of position of rotation.
Have again, owing at the internal diameter of helical spring 47 with keep being provided with between the periphery of rib 60 clearance G about 1mm,, can carry out good dedusting so the periphery of helical spring 47 is entered between the ripple of dust-collecting filter 8 reliably.
