(5) specific embodiment

Be illustrated preferred embodiment of the present invention hereinafter with reference to accompanying drawing.Fig. 1 is the assembly stereogram of the decomposition of one embodiment of the invention with cutter.Among this figure, include: support platform 1, be located at a pair of roller of supporting on the platform 2,3, being located at a pair of roller is the rotating knife 4 of the position of erectility with the support of oil strain element.Barrel cage 5 is that mounting is supported platform 1, and punched-plate 6 is to be located on the barrel cage 5, and when the oil strain element was disintegrated, foreign matters such as cut off machine were to accept with punched-plate, and waste oil is dripped toward barrel cage 5.

According to Fig. 2,3 detailed construction of above-mentioned decomposition with cutter is described, at first, rotating knife 4 is forward end of being located at position adjusting lever 7, and this position adjusting lever 7 is to be located on the support platform 1 towards the mode that described a pair of roller slides freely with front and back.This position adjusting lever 7 has been wholely set round plate 7a in its front end, inserts the sliding tray 1a that is embedded in along the length direction formation of supporting platform 1 by making from the outstanding slide (not shown) in the past below of this round plate 7a, and slides freely before and after can realizing.In addition, at the outer peripheral face of position adjusting lever 7 male thread 7b is set, makes it support the 1b of box thread portion of platform 1 rear end to screw togather with being located at, advancing by spiral also can make its slip.But the 1b of box thread portion is arranged to can realize opening and closing freely by pin 1c, and under the state of opening the 1b of box thread portion, position adjusting lever 7 does not screw togather with the 1b of box thread portion, and can freely slide.That is, when the oil strain element of location, at first, make the 1b of box thread portion form open mode, and position adjusting lever 7 is slided toward the place ahead, thereafter, close the 1b of box thread portion, by screwing togather of male thread 7b and the 1b of box thread portion, and by screw action fine-tuning whole position adjusting lever 7.Therefore, compared to whole situation of sliding by screw action, can quicker the oil strain element be located.When adjusting lever 7 spirals in position are advanced, be the handle 8 that its rear end is located in rotation.

And then rotating knife 4 is the forward end that are positioned position adjusting lever 7, and with turn control stick 9 interlocks.Turn control stick 9 is base axial region 9a of being arranged to make its front end by pivot 9b and but the round plate 7a of position adjusting lever 7 is concentric shape and turn freely.In addition, rotating knife 4 is to be arranged to make its central shaft 4a that the base axial region 9a of turn control stick 9 is rotated from this pivot 9b off-centre.Therefore, as shown in Figure 4, make past more the place ahead of turn control stick 9 (paper right) turn, then the edge of a knife of rotating knife 4 can be given prominence in past more the place ahead (paper right).That is,, can add and subtract the pushing force to oil strain element E of rotating knife 4 by the turn scope of adjusting turn control stick 9.

Secondly, the roller 3 in a pair of roller 2,3, as shown in Figure 5, it is that general throw 10 with pneumatic type rotates as drive source.Promptly form the keyhole 3a of the angle axle key 10a that can insert described throw 10 in roller 3 upper ends.In addition, periphery is provided with engaging tooth 3b below this roller 3, make this engaging tooth 3b as the interlock abutting part and with the below bead butt of oil strain element, by this, the revolving force of roller 3 is passed in the oil strain element, and is made both interlocks rotations.

Then, using method and the effect of the decomposition of above-mentioned formation with cutter is described, after in the mode that contacts with roller 2,3 the oil strain component loading being become erectility, at first, under the state of opening the 1b of box thread portion, position adjusting lever 7 is slided toward the place ahead, after rotating knife 4 contacts and even closely connects with the oil strain element, close the described box thread 1b of portion, and position adjusting lever 7 is advanced toward the place ahead by screw action.Secondly, throw 10 is linked to roller 3 after, drive throw 10.Then, the rotation interlock with itself and roller 3 rotates the oil strain element.Secondly, by operation turn control stick 9, adjust the pushing force of rotating knife to the oil strain element.By such operation, the oil strain element is being rotated for several times, cut off its side face down, waste oil is dripped toward barrel cage, and the inside oil filter that is contained in housing can be decomposed.

According to the decomposition cutter of above-mentioned present embodiment, owing to by throw 10, rotate the oil strain element by roller 3, therefore, operator is only operated swivel lever, can carry out the disassembling operation of oil strain element simply.In addition, because the adjustment to the pushing force of oil strain element of rotating knife 4 is to be undertaken by turn control stick 9, the situation that event is advanced compared to known such spiral by position adjusting lever 7, operation is easier to, and owing to form turn control stick 9 as the point of application, this pivot is as fulcrum, and rotating knife 4 is as the structure of application point, so can carry out the plus-minus of power easily, and strengthen the application of force easily.

In addition, the present invention is not limited to the foregoing description, and it also can do various changes.At first, the container of waste oil is not limited to barrel cage 5, also can be cylinder tank, drip box or other containers, or also can omit.Secondly, also can replace punched-plate, and adopt net.But this is to be used for solid is separated in oil, if do not have this in case of necessity, also it can be omitted.And then, though adopt the whirligig of the throw 10 of pneumatic type, also can adopt electric tool as the oil strain element at the foregoing description.And then, also manual wrench can be linked to roller 3.About this point, in the above-described embodiments, though one of a pair of roller is used roller as driving, and can link with above-mentioned whirligig, but this driving not only can be the structure that links with other whirligig with roller 3, also drive sources such as motor is built in the structure of this roller 3.And then this driving is not limited to the engaging tooth 3b of the foregoing description with roller 3 with the butt linkage part oil strain element, use the revolving force of roller to pass on as long as drive, and rotation driving oil strain element also can.Viewpoint according to this, though also consider the next and oil strain element friction binding of ring of the rubber system that is provided with at roller 3, and make the means of both interlocks, but in this situation, can cause in described butt linkage part can't friction apply if oil permeates, therefore, be preferably the means that prevent the oil contact in above-mentioned linking portion use.

On the other hand, at the foregoing description, though only cut off the housing of oil strain element, the oil filter that is taken out by inside has a discoid metal part in that upper bottom surface is still residual thereafter.Therefore, also can cut off the above-mentioned discoid metal part of decomposition from this oil filter by this recycling plant.That is, because that inner oil filter and oil strain element are all equally is cylindric, and should cut-out portion identical with the below periphery of oil strain element, therefore, when this cut off to decompose, oil filter also can by with the oil strain element same to get location, cut-out, and metal part is separated.But,, certainly also can constitute the cutting apparatus that pushes away of oil filter special use as known techniques in apparatus of the present invention.

And then, in the above-described embodiments,, also can not use this throw, and directly rotate the oil strain element though rotate the oil strain element indirectly with roller 3 by the driving that links with other throw.That is, also can wait and directly rotate the oil strain element by the exchange spanner.In the present invention, it the most important thing is rotating knife 4 is arranged to pivot 9b off-centre from swivel lever 9.

In addition, in the above-described embodiments, though come support the oil strain element at 3 by the combination of a pair of roller and rotating knife, the number of roller and rotating knife is not limited to this, also can increase its number of change.That is, if increase the number of roller, then can more stable support oil strain element, in addition,, then can quicker, positively cut off the oil strain element if increase the number of rotating knife.

As previously discussed, the decomposition cutter of oil strain element of the present invention, owing to be that rotating knife is arranged to pivot off-centre from swivel lever, so can easily add and subtract the pushing force of rotating knife to the oil strain element.In addition, owing to rotate the oil strain element by at least one roller, so rotate this roller automatically as if waiting with internal motor, then operator is only operated the disassembling operation that the turn control stick can carry out the oil strain element.In addition, owing to rotate roller by general throw, thus make the formation of rotating mechanism simple, and by using general utility tool also very reasonable.And then, owing to imbed the interlock abutting part of flange below the oil strain element in the roller setting, so the revolving force of roller more positively can be passed in the oil strain element.And then owing to adopt the throw of pneumatic tool, can form the safety formation of the anxiety that waste oil is had catch fire etc. so can not produce heat as roller.
