Summary of the invention

-invention to solve technical matters-

But, the in the situation that of the disclosed fixed type dividing plate of patent documentation 1, need to make the whole surface of clamp-oning plate all form very smoothly.In this case, if make and clamp-on plate with metal, need derby to cut to form to clamp-on plate; If form and clamp-on plate with weldment, need weld zone to process to such an extent that very smoothly form and clamp-on plate, this just becomes the major cause that manufacturing cost is high.Also there is the problem that plate and dividing plate are interfered mutually owing to clamp-oning the manufacturing errors of plate, distortion while using etc. of clamp-oning.

On the other hand, even in dividing plate lower end with clamp-on the very little gap of existence between plate and also can expect that rubbish can not flow backwards in following three kinds of situations.That is, this gap is very little for the rubbish loading, or dividing plate lower end and the gap of clamp-oning between plate is filled out with elastomeric elements such as sealing members, or arranges and bite anti-locking mechanism in addition.

So, can consider to form and clamp-on plate, actively ensure in dividing plate lower end and clamp-on between plate, to reserve minim gap, but because what clamp-on that plate carries out is the compound movement that is accompanied by rotation and revolution, so be difficult to suitably form gap.For example, even the position of dividing plate lower end is set to ensure to obtain desirable gap under the regulation anglec of rotation of clamp-oning plate, but in the time clamp-oning plate and rotate from here on, this gap will disappear, clamp-oning plate and dividing plate will interfere mutually, and this situation once occurred.Manufacture and not only suitably formed described gap but also the solid and lightweight plate of clamp-oning is a very difficult thing.

In the situation that using in patent documentation 1 disclosed movable dividing plate, although can freely form to a certain degree the surface configuration of clamp-oning plate, the lower end of downside dividing plate is gone to follow and is always accomplished and the Surface Contact of clamp-oning plate.

But, under the movable diaphragm structure of reality, because the pendulum radius of downside dividing plate and hunting range are larger, clamp-on the situation in rotary moving of plate so exist downside dividing plate following, and have the problem that rubbish is bitten, flow backwards.

The present invention has put just in view of the above problems.Its object is: provide a kind of can suitably form the lower end of stationary barrier and clamp-on gap between plate comprise that again the planetary rotation of clamp-oning plate of solid, lightweight and easy manufacture clamp-ons board-like refuse collector.

-in order to the technical scheme of technical solution problem-

For reaching above-mentioned purpose, in this invention, make dividing plate and clamp-on the gap minimum between plate.

Particularly, in the invention of first aspect, taking comprise the rubbish of the peristome that is connected to rubbish container case drop into case, be arranged on this rubbish drop into case the side relative with this peristome dividing plate and be located at refuse collector that this rubbish drops into the rubbish loader mechanism of clamp-oning again described peristome one side the garbage-compressing in case, the input port of dropping into case from this rubbish being dropped into from described dividing plate below as object.Described rubbish loader mechanism comprises rotating bearing component and clamp-ons plate, and the opposing sidewalls that this rotating bearing component drops into case by described rubbish supports, and can rotate.This is clamp-oned plate and rotates centered by being supported the rotating shaft that can establish to be eccentric in the centre of gration of this rotating bearing component, this is clamp-oned plate and is configured to: in described rotating bearing component rotates time of 1 week, rotate in the same direction 1/2 week, and rotate facing to approaching under the state of fixing shape lower end of described dividing plate on surface, described in clamp-on plate and be formed as: meet b >=2a from the centre of gration of described rotating bearing component to the offset a in the axle center of described rotating shaft and from the axle center of this rotating shaft to this relation of clamp-oning the distance b of one end of plate.

According to said structure, because make the relation between offset a and distance b meet b >=2a, be the situation of crossed loops so there will not be the track of a pair of ora terminalis of clamp-oning plate.So, in the case of connection clamp-on the direction of a pair of ora terminalis of plate and the bearing of trend of dividing plate consistent, can prevent the lower end of the dividing plate being fixed and clamp-on that gap between the surface of plate is large must exceed needs.Consequently, can suitably form the lower end of dividing plate and clamp-on the gap between plate.Track at the ora terminalis of clamp-oning plate becomes crossed loops, drop into the ora terminalis of clamp-oning plate of spatial portion one side because move to rubbish from the below extended line of dividing plate at the beginning, can increase on one side at once afterwards the gap between itself and dividing plate, on one side again from the below extended line of dividing plate 21 towards rubbish container case 3 one side shiftings, the problem that exists rubbish easily to be bitten.As the present invention form clamp-on plate make b >=2a relation set up after, just there will not be such problem.

The invention of second aspect is such, in the invention of first aspect, the described described surface polylith plate-shaped member of clamp-oning plate forms, and looks and is configured to symmetrical with the axle center holding point of this rotating shaft and to form the described plate-shaped member of the face of clamp-oning of rubbish higher than the intensity that forms the described plate-shaped member on surface described in another from the axis direction of described rotating shaft.

According to said structure, can either guarantee needs the high-intensity intensity of clamp-oning face, and after not needing high-intensity place intensity weakened, weight will correspondingly lighten thereupon, can form to such an extent that weight is lighter as the whole plate of clamp-oning.Consequently, can obtain and comprise solid, the lightweight refuse collector of clamp-oning plate.

The invention of the third aspect is such, in the invention of second aspect, is provided with multiple ribs in described inside of clamp-oning plate, the joint situation of this rib and described plate-shaped member be in described surface with described in to clamp-on the face that face is relative more firm.

According to said structure, less at the joint of clamp-oning face one side rib and plate-shaped member, thereby just can correspondingly reduce worker time and make weight lighter thereupon.Because what be applied to the face of clamp-oning one side is only compressive force substantially, so even if clamp-on the rib of face one side and the joint of plate-shaped member tails off, also can fully suppress to clamp-on plate distortion.The one side relative with the face of clamp-oning that on the other hand, also can be applied in pulling force can be guaranteed intensity fully by firmly engaging.

The invention of fourth aspect is such, and first, in the invention of third aspect either side, the pair of end portions of clamp-oning plate described in seeing from the axis direction of described rotating shaft is separately installed with strengthening part.

According to said structure, can be to dropping into the input port side edge of case bottom at rubbish and clamp-oning rubbish between plate and the end of clamp-oning plate need to especially with intensity such as can be bitten and carry out part reinforcement.Consequently, can form the solid and lightweight plate of clamp-oning.

The invention of the 5th aspect is such, first in the invention of third aspect either side, described in clamp-on plate and be formed as: described offset a, this clamp-ons the thickness W of plate, see from the axis direction of described rotating shaft described in clamp-on the distance L between a pair of ora terminalis of plate ₀, and this pass of clamp-oning between size and the manufacturing errors δ of plate be L ₀=4a+W+ δ.

The position of described dividing plate lower end is configured to: the distance L from this lower end to described centre of gration ₁, pass between described offset a, described thickness W, gap α is L ₁=a+W/2+ α+δ.

Distance L on the described described surface relative with this dividing plate of clamp-oning plate, from the point by connection this lower end of this dividing plate and the straight line of described centre of gration to described centre of gration ₂be always 0 < L ₂≤ L ₁ground forms the shape of stating to some extent the described surface of clamp-oning plate, irrelevant with the rotation situation of clamp-oning plate.Clamp-on the size of plate and the value of manufacturing errors δ is less than gap α.

According to said structure, no matter in the case of connection clamp-on the direction of a pair of ora terminalis of plate and the bearing of trend of dividing plate consistent or vertical, can both make the lower end of the dividing plate of having fixed and clamp-on gap between the surface of plate in specified value and error limit thereof.Irrelevant with the rotation situation of clamp-oning plate, can make the lower end of dividing plate always and clamp-on gap between the surface of plate in the gap α of regulation.Consequently, can make refuse collector more be difficult to the bad phenomenon that occurs that rubbish is bitten or rubbish flows backwards.

-invention effect-

As mentioned above, according to the present invention, in refuse collector, be b >=2a from the centre of gration of rotating bearing component to the offset a of rotating shaft core, from the axle center of this rotating shaft to the pass of clamp-oning the distance b of one end of plate, the track that has prevented a pair of ora terminalis of clamp-oning plate becomes crossed loops, can suitably form in refuse collector the lower end of stationary barrier and clamp-on the gap between plate and can make this refuse collector comprise the plate of clamp-oning of solid, lightweight, easy manufacture.

On the periphery of circular rotating support unit 22, be formed with and comprise the stage portion 223 being formed by minor diameter part 221 and large-diameter portion 222.On the lateral surface of rotating bearing component 22 and its centre of gration porose portion 224 is set.Center shaft 22a is entrenched in the hole portion 224 of this rotating bearing component 22 through being arranged on medium pore 32a on rotating bearing component side chain wheel 32, rotating bearing component 22 is subject to supporting and can rotates around center shaft 22a.

The outside, left and right of center shaft 22a has formed discoideus brim part 22b, is formed with for example four screw hole 22c at this brim part 22b.On the sidewall 6a of left and right, be formed with respectively through hole 6b concentric with center shaft 22a and that internal diameter is slightly larger than the external diameter of rotating bearing component 22.The minor diameter part 221 of the stage portion 223 of rotating bearing component 22 is accommodated in this through hole 6b.While being fixed with side-looking around through hole 6b on sidewall 6a, be the fixed support 23 (representing with long and two-short dash line in Fig. 4) of " T " font, bolt 22e is inserted in the bolt hole 22d on this fixed support 23 and tightened in screw hole 22c, and center shaft 22a is fixed on sidewall 6a.So, rotating bearing component 22 is just directly being supported by sidewall 6a, and the minor diameter part 221 of its stage portion 223 can rotate in through hole 6b.Rotating bearing component 22 by sidewall 6a false bearing through fixed support 23 and center shaft 22a.By large-diameter portion 222 and the movement of center shaft 22a restricting rotation support unit 22 on left and right directions of stage portion 223.

Speed reduction gearing 24 comprises the deceleration sprocket wheel 24a that for example external diameter is larger than drive sprocket 31, drive sprocket 31 and deceleration sprocket wheel 24a is tied with the first rough lock 24b; Be tied taking turns 32 at the sprocket wheel 24c (only dotting in Fig. 4) of close sidewall 6a mono-side of deceleration sprocket wheel 24a (inner side, left and right) and rotating bearing component side chain with the second rough lock 24d.

A rotating shaft 25 is supported between a pair of rotating bearing component 22 and is eccentric on the position of center shaft 22a, can rotate.In this rotating shaft 25, be provided with between the sidewall 6a of left and right, extend clamp-on plate 26, this clamp-ons plate 26 and this rotating shaft 25 one rotations.

As shown in Figure 12～Figure 15, clamp-on plate 26 and there is the leaf shape form that section presents two ends point, for example made by Plate Welding part.Particularly, clamp-on polylith for surface (four in the present embodiment) plate-shaped member 40,41 formation of plate 26.For example, the drawing product that plate-shaped member 40,41 is steel plate.The axis direction that is arranged to the rotating shaft 25 from clamp-oning plate 26 in plate-shaped member 40,41 is looked symmetrical with the AnchorPoint of this rotating shaft 25 and is become the face of the clamp-oning side plate-shaped member 40 of the face of clamp-oning of rubbish 55, and its intensity is set to that to clamp-on the intensity of opposition side plate-shaped member 41 of another surperficial 26a of plate 26 than formation high.For example preferably make the thickness of slab of the thickness ratio opposition side plate-shaped member 41 of clamp-oning face side plate-shaped member 40 thick, or face side plate-shaped member 40 is clamp-oned in the higher high tension steel formation of mechanical strength.

As shown in figure 13, opposition side plate-shaped member 41 is by bending, and its base end part becomes towards the axially extended vertical rib 43a that clamp-ons plate 26.Two opposition side plate-shaped members 41 are joined together by welding securely to wait in vertical rib 43a part.In opposition side plate-shaped member 41, form the part of surperficial 26a, leave predetermined distance and be formed with multiple bending part 41a that extend vertically.As shown in figure 14, at this bending part, 41a positions, and the vertical rib 43b that section is " コ " font just waits by welding and is bonded together with the back side of opposition side plate-shaped member 41.Here, because it is very large to insert the space of solder bar, so opposition side plate-shaped member 41 and vertical rib 43b are by weld together securely.Opposition side plate-shaped member 41 and vertical rib 43b are welded on the side parts 47 that comprise axle sleeve (boss) portion 46 securely, and opposition side plate-shaped member 41 is also welded on the multiple trapezoidal cross rib 44 of extension perpendicular to axial direction securely.

On the other hand, as shown in figure 15, when face side plate-shaped member 40 is clamp-oned in welding, a relative side is sealed by opposition side plate-shaped member 41, so cannot fully clamp-on the welding of face side plate-shaped member 40 and vertical rib 43b and cross rib 44.Therefore, desirable way is, for example, opening (not shown) is set clamp-oning face side plate-shaped member 40 1 sides, carries out and the welding of indulging rib 43b, cross rib 44, or carry out keyhole welding etc. and carry out part welding from this part.So, clamp-on face side plate-shaped member 40 and reduce with the weld of vertical rib 43b and cross rib 44, when worker can correspondingly be reduced according to the minimizing of this weld in limit, and make lightweight.Almost only compressive is applied to and clamp-ons on face side plate-shaped member 40, so even if clamp-oning face side plate-shaped member 40 reduces with the weld of vertical rib 43b and cross rib 44, also can suppress fully to clamp-on plate 26 and be out of shape.On the other hand, opposition side plate-shaped member 41 welding that pulling force also can be applied thereto are carried out very fully, can guarantee enough intensity.

As shown in figure 15, be welded with the section strengthening part 45 of approximate " L " font respectively in the pair of end portions of clamp-oning plate 26.This strengthening part 45 releasably can be installed, in the time of wearing and tearing, breakage, again this strengthening part be changed.Can to the input port side edge that drops into case 6 bottoms at rubbish with clamp-on between plate 26 rubbish 55 and understand be bitten etc. and need especially the end of clamp-oning plate 26 of intensity to carry out part reinforcement.Be reinforced parts 45 and cover because clamp-on the face of joint of face side plate-shaped member 40 and opposition side plate-shaped member 41, improve so clamp-on intensity and the rigidity of plate 26.By increasing the area of the face of the clamp-oning side plate-shaped member 40 that is applied thereto of compressive force, reduce the area of opposition side, can suppress strengthening part 45 total qualities increases.Consequently can form the solid and lightweight plate 26 of clamp-oning.In addition,, if accomplish only can change strengthening part 45, just need not change and wholely clamp-on plate 26, and for ease of maintenaince, be desirable way.

As shown in Fig. 1 waits, on a relative effects on surface 26a on thickness direction who clamp-ons plate 26 who makes like this, be provided with multiple (in present embodiment being 14) ridge 33, each ridge 33 is keeping interval and is establishing at the axis direction (overall width direction, left and right directions) of rotating shaft 25.In the present embodiment, the shape of each ridge 33 is roughly the same, is formed as extending along the direction vertical with the axis direction of rotating shaft 25.Ridge 33 has from the axis direction outer peripheral edges that gently changing from clamp-oning height that the surperficial 26a of plate 26 counts of looking.Corresponding to this, be formed with each ridge 33 by the notch passing through 34 at the bottom of dividing plate 21 21b.Make in the present embodiment ridge 33 be formed as lamellar, but be not limited to this, in order to improve intensity, can to make the section of ridge 33 be triangle or trapezoidal etc.And it is concavo-convex to utilize punching press or casting etc. to form on the surface of clamp-oning plate 26, by its convex portion formation ridge 33.Ridge 33 is waited with surperficial 26a and is engaged by welding.

As shown in Figures 3 and 4, rotating shaft 25 is configured to: in that time rotating a circle at rotating bearing component 22, this rotating shaft 25 utilize be arranged on its end clamp-on plate speed reduction gearing 27 towards 1/2 of the rotation amount of this rotating bearing component 22 of same direction rotation.Particularly, clamp-on plate with in speed reduction gearing 27, with the first sprocket wheel 27a of center shaft 22a one rotation, be bound up with rotation adjusting chain 27c with the second sprocket wheel 27b of rotating shaft 25 one rotations, the idler sprockets 28a of automatic takeup 28.The lever-like automatic takeup main body 28b of automatic takeup 28, by 32 supportings of rotating bearing component side chain wheel, can rotate centered by rotational pin 28c.Can regulate rotation to regulate the tension force with chain 27c by regulating rotary momentum (amount of spin) adjusting bolt 28d.Automatic takeup main body 28b is fixed on rotating bearing component side chain wheel 32 with captive nut 28e after regulating tension force.The ratio of the pitch circle diameter of the pitch circle diameter of the first sprocket wheel 27a and the second sprocket wheel 27b is 1: 2.In addition, in figure, depict simply each chain and each sprocket wheel.

Therefore,, as shown in Fig. 7～Figure 11, a pair of ora terminalis track of clamp-oning plate 26 of seeing from the axle center of rotating shaft 25 is being described respectively the so-called cardioid 29b roughly cardioid 29c similar to it.This cardioid 29b and roughly cardioid 29c are heart-shaped tracks, by making this track be formed as dropping into the bottom of spatial portion 6d and the wall 6c that looks and be circular-arc from the left and right side of vehicle along forming rubbish, clamp-oning plate 26 will compress the rubbish 55 of the bottom of dropping into rubbish input spatial portion 6d on one side, reliably this rubbish 55 is extruded into the below of dividing plate 21 on one side.

As mentioned above, in the present embodiment, the ora terminalis of clamp-oning plate 26 in order to allow using depict this cardioid 29b and roughly the mechanism of cardioid 29c be the circular rotating support unit 22 embedding in the through hole 6b of sidewall 6a.Be arranged on sidewall 6a with shaft-like rotating bearing component and clamp-on compared with the situation (with reference to patent documentation 1) between plate 26, after circular rotating support unit 22 is embedded in through hole 6b, having solved following problem.That is to say, the problem existing the in the situation that of shaft-like rotating bearing component is: clamp-on the effective length of plate in pivot center direction short, but lengthen in next this effective length that can make of situation of circular rotating support unit 22; Another problem existing the in the situation that of shaft-like rotating bearing component is: at sidewall 6a with clamp-on between plate 26 and there will be gap, rubbish is easy to flow backwards, but the in the situation that of circular rotating support unit 22, can make sidewall 6a and clamp-on gap between plate 26 as far as possible little; The another problem existing the in the situation that of shaft-like rotating bearing component is: easily distortion, and the in the situation that of circular rotating support unit 22, be difficult to distortion, thereby can make to clamp-on the spin stabilization of plate 26.

Then, this cardioid 29b and roughly have a sunk part (recess 29a) on cardioid 29c.In the present embodiment, this recess 29a is arranged on the lower end 21c of the bottom 21b of dividing plate 21 roughly on consistent position.Therefore,, under example readiness for action as shown in Figure 7, that sees from the axis direction of rotating shaft 25 clamp-ons plate 26 middle body in the longitudinal direction near lower end 21c; Under the state shown in Figure 10, the ora terminalis of clamp-oning plate 26 approaches lower end 21c, makes as much as possible this clamp-on between plate 26 and lower end 21c and do not have gap in the rotary course of clamp-oning plate 26.For accomplishing this point, must consider for the position of the lower end 21c of dividing plate 21, the shape of clamp-oning plate 26 relational expression of regulation.

So, first, epicycloid and cardioid are explained.As shown in figure 16, will make radius r ₂round C _r2one side and radius r ₁-r ₂round C _awhen circumscribed one side fricton-tightly rotates down, radius r ₂circumference on the curve described of moving some P be called epicycloid.In Figure 16, suppose round C _r2on one side with circle C _athe rotation of circumscribed one side, circle C _r2center T come ∠ TOD=θ _r1position.Now, at first at A point and circle C _athe round C of contact _r2on point come P1 point.Because moving, moving some P ensures line minute PP ₁become round C _r2diameter, so a moving some P comes ∠ PTB '=θ _r1+ θ _r2position.

Now, because circle C _awith circle C _r2always contacting and moving, so arc DV and arc P ₁v's is equal in length.Therefore, due to arc DV=(r ₁-r ₂) θ _r1and arc P ₁v=r ₂θ _r2so, (r ₁-r ₂) θ _r1=r ₂θ _r2, obtain θ _r2=((r ₁-r ₂)/r ₂) θ _r1, following formula (1) is set up.

$\&angle;{\mathrm{PTB}}^{\text{'}}={\mathrm{\&theta;}}_{r1}+{\mathrm{\&theta;}}_{r2}={\mathrm{\&theta;}}_{r1}+\frac{r_1-r_2}{r_2}{\mathrm{\&theta;}}_{r1}=\frac{r_1}{r_2}{\mathrm{\&theta;}}_{r1}...\left(1\right)$

Suppose as circle C _r2around circle C _awhile circling, moving some P turns two weeks and returns to A point, θ _r1when=2 π, become 4 π.Formula (1) becomes (r ₁/ r ₂) × 2 π=4 π, and obtain r ₂=r ₁/ 2, ∠ PTB '=2 θ _r1.

Because circle C _r2center T be positioned at from x axle along radius r ₁circumference turn an angle θ _r1the position at rear place, so vector OT=r ₁(cos θ _r1, sin θ _r1).

Because moving some P is positioned at from B ' along radius r ₂=r ₁the circumference of/2 round Cr2 turns an angle θ _r1+ θ _r2=2 θ _r1the position at rear place, so vector TP=(r ₁/ 2) (cos2 θ _r1, sin2 θ _r1).

Therefore, vector OT+ vector TP=(r ₁(cos θ _r1+ (1/2) cos2 θ _r1), r ₁(sin θ _r1+ (1/2) sin2 θ _r1)), like this, x coordinate, y coordinate that following formula (2) is ordered for P are set up.

$\left.\begin{array}{c}x=r_1(\cos {\mathrm{\&theta;}}_{r1}+\frac{1}{2}\cos 2{\mathrm{\&theta;}}_{r1})\\ y=r_1(\sin {\mathrm{\&theta;}}_{r1}+\frac{1}{2}\sin 2{\mathrm{\&theta;}}_{r1})\end{array}\right\}...\left(2\right)$

Formula (2) is on mathematics, to be commonly referred to as the formula that intermediate variable represents.The represented track of formula (2) becomes at 0≤θ _r1in the scope of≤2 π, become laterally zygomorphic shape.In Figure 16, be recess towards left shape.

Then, at 0≤θ _r1the formula of the half of the Range Representation cardioid of≤2 π describes.Circle C in consideration formula (1) _r2around circle C _awhile turning two weeks, moving some P turns 1 week and returns to the situation that A is ordered.In this case, because as circle C _r2around circle C _awhile circling, moving some P just turns half cycle, so just mean at 0≤θ _r1in the scope of≤2 π, describe the half shape of cardioid.That is to say, work as θ _r1when=4 π, ∠ PTB '=(r ₁/ r ₂) θ _r1, become 2 π.Learnt (r by formula (1) ₁/ r ₂π=2) × 4 π ∴ r ₂=2r ₁, ∠ PTB '=θ _r1/ 2.

Circle C _r2center T be positioned at from x axle along radius r ₁circumference turn an angle θ _r1the position at rear place, so vector OT=r ₁(cos θ _r1, sin θ _r1).

Because moving some P is positioned at from A ' along radius r ₂=2r ₁round C _r2circumference turn θ _r1+ θ _r2=θ _r1the position at/2 rear places, so vector TP=2r ₁(cos (θ _r1/ 2), sin (θ _r1/ 2)).Therefore, vector OT+ vector TP=(r ₁(cos θ _r1+ 2cos (θ _r1/ 2)), r ₁(sin θ _r1+ 2sin (θ _r1/ 2))) set up.

Therefore x coordinate, y coordinate that, following formula (3) is ordered for P are set up.

$\left.\begin{array}{c}x=r_1(\cos {\mathrm{\&theta;}}_{r1}+2\cos (\frac{{\mathrm{\&theta;}}_{r1}}{2})=r_1\cos {\mathrm{\&theta;}}_{r1}+{2r}_1\cos \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\\ y=r_1({\sin \mathrm{\&theta;}}_{r1}+2\sin (\frac{{\mathrm{\&theta;}}_{r1}}{2})=r_1\sin {\mathrm{\&theta;}}_{r1}+{2r}_1\sin \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\end{array}\right\}...\left(3\right)$

Next, the track of the ora terminalis of clamp-oning plate 26 is analyzed.This refuse collector clamp-on that plate 26 revolves round the sun centered by revolution center O and with the speed of revolution speed half along the direction rotation identical with revolution direction.As shown in figure 17, establishing the rotation center of clamp-oning plate 26 is S, and establishing the eccentric distance of clamp-oning plate 26 is a, and establishing the length from rotation center to one end of clamp-oning plate 26 is b, and establishing the one end of clamp-oning plate 26 is P, and establishing revolution angle is θ _r1, establishing rotation angle is θ _r2.

Now, vector OS=a (cos θ _r1, sin θ _r1), vector S P=b (cos θ _r2, sin θ _r2), the coordinate that P is ordered is the vector of vector OS and vector S P, vector OP=vector OS+ vector S P=(acos θ _r1+ bcos θ _r2, asin θ _r1+ bsin θ _r2).

Therefore the xy coordinate that, P is ordered is represented by following formula (4).

$\left.\begin{array}{c}x=a\cos {\mathrm{\&theta;}}_{r1}+b\cos {\mathrm{\&theta;}}_{r2}\\ y=a\sin {\mathrm{\&theta;}}_{r1}+b\sin {\mathrm{\&theta;}}_{r2}\end{array}\right\}...\left(4\right)$

$\left.\begin{array}{c}x=a\cos {\mathrm{\&theta;}}_{r1}+b\cos \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\\ y=a\sin {\mathrm{\&theta;}}_{r1}+b\sin \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\end{array}\right\}...\left(5\right)$

Because described formula (3) the x coordinate, the y coordinate that all represent P order the same as described formula (5), two formulas are done to one relatively, can be by a=r ₁, b=2r ₁obtain following formula (6).

b＝2a …(6)

That is to say, be 2 times of eccentric distance a in the case of clamp-oning the length b from rotation center to one end of plate 26, clamp-ons the ora terminalis P of plate 26 at 0≤θ _r1≤ 2 π depict the track of the first half within the scope of this.

Here be point-symmetric Q point with respect to revolution center O and the ora terminalis P that clamp-ons plate 26 also the same with P point, at 0≤θ, _r1≤ 2 π depict the track of the latter half within the scope of this.

Therefore, P point and Q point are depicted a complete track jointly.θ _r1position and θ that when=2 π, P point and Q are ordered _r1within=0 o'clock, exchange.

Next, while asking the length of SP, because the coordinate of S is (acos θ _r1, asin θ _r1), so following formula (7) is set up.

$\stackrel{\&OverBar;}{\mathrm{SP}}=\sqrt{{(a\cos {\mathrm{\&theta;}}_{r1}+2a\cos \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)-a\cos {\mathrm{\&theta;}}_{r1})}^2+{(a\sin {\mathrm{\&theta;}}_{r1}+2a\sin \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)-a\sin {\mathrm{\&theta;}}_{r1})}^2}$

$=\sqrt{{4a}^2({\cos }^2\left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)+{\sin }^2\left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right))}=\sqrt{{4a}^2}=2a...\left(7\right)$

Hence one can see that, and the length of SP is irrelevant with revolution angle, the rotation angle of clamp-oning plate 26, is maintaining 2a always.

The length that equally also can calculate SQ is 2a, so hence one can see that: the length of PQ is irrelevant with revolution angle, the rotation angle of clamp-oning plate 26, is maintaining 4a always.This shows total length L ₀=4a clamp-on plate 26 with two ora terminalis always on curve 29b mobile mode rotate.

Next, the basic form of the ora terminalis track of clamp-oning plate 26 is explained.That is to say, as shown in figure 18, consider the situation of b > 2a in formula (5).Dividing plate 21 is arranged on x axle, extends along x direction of principal axis.

Now, can be expressed as b=2a+c.By b=2a+c substitution formula (5), x coordinate, y coordinate that P is ordered just can be represented by following formula (8).

$\left.\begin{array}{c}x=a\cos {\mathrm{\&theta;}}_{r1}+(2a+c)\cos \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\\ y=a\sin {\mathrm{\&theta;}}_{r1}+(2a+c)\sin \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\end{array}\right\}...\left(8\right)$

The length of SP is SP=√ ((acos θ _r1+ (2a+c) cos (θ _r1/ 2)-acos θ _r1) ²+ (asin θ _r1+ (2a+c) sin (θ _r1/ 2)-asin θ _r1) ²)=√ ((2a+c) ²(cos ²(θ _r1/ 2)+sin ²(θ _r1/ 2))=√ (2a+c) ²=2a+c.Hence one can see that, and the length of SP is irrelevant with revolution angle, the rotation angle of clamp-oning plate 26, is maintaining 2a+c always.

The length that equally also can calculate SQ is 2a+c, so hence one can see that: the length of PQ is irrelevant with revolution angle, the rotation angle of clamp-oning plate 26, is maintaining 4a+2c always.

Therefore, if (9) set the total length L that clamp-ons plate 26 according to the following formula ₀,

L _o＝4a+2c…(9)

Two ora terminalis clamp-oning plate 26 will always move on same roughly cardioid 29c.

When set the total length L that clamp-ons plate 26 according to formula (9) ₀time, from formula (8), x coordinate, the y coordinate of clamp-oning plate 26 can be accompanied by θ _r1variation get following value.

If θ _r1=0, x=acos (0)+(2a+c) cos (0)=a × 1+ (2a+c) × (1)=3a+c and y=asin (0)+(2a+c) sin (0)=a × (0)+(2a+c) × 0=0.

If θ _r1=π, x=acos (π)+(2a+c) cos (pi/2)=a × (1)+(2a+c) × 0=-a and y=asin (π)+(2a+c) sin (pi/2)=a × 0+ (2a+c) × 1=2a+c.

If θ _r1=2 π, following formula (10) is set up.

$\left.\begin{array}{c}x=a\cos \left(2\mathrm{\&pi;}\right)+(2a+c)\cos \left(\mathrm{\&pi;}\right)=a\&times;1+(2a+c)\&times;(-1)=-a-c\\ y=a\sin \left(2\mathrm{\&pi;}\right)+(2a+c)\sin \left(\mathrm{\&pi;}\right)=a\&times;\left(0\right)+(2a+c)\&times;0=0\end{array}\right\}...\left(10\right)$

Next, not only consider to clamp-on the ora terminalis P of plate 26, the situation of movement of Q, also consider to clamp-on the width W of plate 26.When clamp-oning length direction the be θ parallel with y direction of principal axis of plate 26 _r1when=π, set W to ensure clamp-oning gap α between plate 26 and dividing plate 21 as a suitable value.Work as θ _r1when=π, represented by x=-a, y=0 because clamp-on x coordinate, the y coordinate of the rotation center S ' of plate 26, represented by following formula (11) so clamp-on x coordinate, the y coordinate of the surface relative with dividing plate 21 of plate 26 and the intersection point of x axle.

$\left.\begin{array}{c}x=-a-\frac{W}{2}\\ y=0\end{array}\right\}...\left(11\right)$

Next, as long as by parallel with x direction of principal axis the length direction of clamp-oning plate 26 θ of being _r1the gap of clamp-oning when=2 π between plate 26 and dividing plate 21 is set for and θ _r1identical when=π, from formula (10), formula (11), need

This relation of-a-c=-a-W/2 is set up.

Therefore, following formula (12) is set up.

$c=\frac{W}{2}...\left(12\right)$

Consequently, from formula (9) and formula (12), as long as meet following formula (13)

L _o＝4a+W…(13)

No matter in the case of clamp-on the length direction of plate 26 parallel with x direction of principal axis, or parallel with y direction of principal axis in the situation that, the gap α clamp-oning between plate 26 and dividing plate 21 can both be set as to same value.Therefore, consider theoretically, from management dividing plate 21 and clamp-on gap between plate 26 this to meet this formula (13) be on the one hand a kind of ideal situation.

Next, b and L are described ₀the alteration of form of clamp-oning plate 26 that causes of value.

First, as shown in figure 19, clamp-oning plate 26 for b=2a, L ₀in the situation of ≠ 4a+W, clamp-on length direction the be θ parallel with y direction of principal axis of plate 26 _r1when=π, plate 26 surfaces of clamp-oning of dividing plate 21 1 sides are (a-W/2,0) with the coordinate of the intersection point of x axle, and the gap of clamp-oning between plate 26 and dividing plate 21 is α.

On the other hand, when clamp-oning length direction the be θ parallel with x direction of principal axis of plate 26 _r1=0, when 2 π, the coordinate of clamp-oning plate 26 ora terminalis of dividing plate 21 1 sides is (a, 0), and gap between dividing plate 21 is α+W/2.

In addition, the in the situation that of b=2a, L as shown in Figure 19 ₀=4a, so cannot set the width of clamp-oning plate 26 to realize L ₀=4a+W., clamp-on gap between plate 26 and dividing plate 21 and can have that W/2's is poor with in these two kinds of situations of situation parallel with x direction of principal axis in the length direction of clamp-oning plate 26 situation parallel with y direction of principal axis.But, if make as much as possible width W thinner, can dwindle the poor of this gap.

Next be, b > 2a, L to the plate 26 of clamp-oning shown in Figure 18 ₀the situation of=4a+W is done simple explanation.When clamp-oning length direction the be θ parallel with y direction of principal axis of plate 26 _r1when=π, plate 26 surfaces of clamp-oning of dividing plate 21 1 sides are (a-W/2,0) with the coordinate of the intersection point of x axle, and the gap of clamp-oning between plate 26 and dividing plate 21 is α.On the other hand, when clamp-oning length direction the be θ parallel with x direction of principal axis of plate 26 _r1=0, when 2 π, the coordinate of clamp-oning plate 26 ora terminalis of dividing plate 21 1 sides is (W/2,0), and the gap of clamp-oning between plate 26 and dividing plate 21 is α.

Omit diagram, to clamp-oning plate 26 for b > 2a, L ₀the situation of ≠ 4a+W is done simple explanation.In this case, when clamp-oning length direction the be θ parallel with y direction of principal axis of plate 26 _r1when=π, plate 26 surfaces of clamp-oning of dividing plate 21 1 sides are (a-W/2,0) with the coordinate of the intersection point of x axle, and the gap of clamp-oning between plate 26 and dividing plate 21 is α.On the other hand, clamp-on length direction the be θ parallel with x direction of principal axis of plate 26 _r1=0, when 2 π, the coordinate of clamp-oning plate 26 ora terminalis of dividing plate 21 1 sides is (W/2,0), but the gap of clamp-oning between plate 26 and dividing plate 21 becomes α+γ.That is to say, clamp-on gap between plate 26 and dividing plate 21 and have a difference γ in the length direction of clamp-oning plate 26 situation parallel with y direction of principal axis with under the situation both of these case parallel with x direction of principal axis.

In addition, the in the situation that of described b > 2a, more increase b, roughly the recess of curve 29c will be milder and move closer to circle (omitting diagram).

Next, as shown in figure 20, consider to clamp-on plate 26 for b < 2a, L ₀the situation of ≠ 4a+W.In this case, in formula (5), can be expressed as b=2a-c.By in its substitution formula (5), x coordinate, y coordinate that P is ordered are represented by following formula (14).

$\left.\begin{array}{c}x=a\cos {\mathrm{\&theta;}}_{r1}+(2a-c)\cos \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\\ y=a\sin {\mathrm{\&theta;}}_{r1}+(2a-c)\sin \left(\frac{{\mathrm{\&theta;}}_{r1}}{2}\right)\end{array}\right\}...\left(14\right)$

Now, SP=√ ((acos θ _r1+ (2a-c) cos (θ _r1/ 2)-acos θ _r1) ²+ (asin θ _r1+ (2a-c) sin (θ _r1/ 2)-asin θ _r1) ²)=√ ((2a-c) ²(cos ²(θ _r1/ 2)+sin ²(θ _r1/ 2))=√ (2a-c) ²=2a-c.

Hence one can see that, and the length of SP is irrelevant with revolution angle, the rotation angle of clamp-oning plate 26, is maintaining 2a-c always.

Because can calculate equally the length of SQ is 2a-c, so the length of known PQ is irrelevant with revolution angle, the rotation angle of clamp-oning plate 26, maintaining 4a-2c always.

Therefore, as long as (15) set the total length of clamp-oning plate 26 according to the following formula,

L _o＝4a-2c…(15)

These two ora terminalis will always move on same curve.This curve becomes crossed loops 29d (so-called limacon state).

According to total length L ₀when=4a-2c sets and clamp-ons the total length of plate 26, along with θ _r1the x coordinate of clamp-oning plate 26 that obtained by formula (8) of variation, that y sits target value is as follows.

If θ _r1=0, x=acos (0)+(2a-c) cos (0)=a × 1+ (2a-c) × (1)=3a-c and y=asin (0)+(2a-c) sin (0)=a × (0)+(2a-c) × 0=0

If θ _r1=π, x=acos (π)+(2a-c) cos (pi/2)=a × (1)+(2a-c) × 0=-a and y=asin (π)+(2a-c) sin (pi/2)=a × 0+ (2a-c) × 1=2a-c.

θ _r1when=2 π, following formula (16) is set up.

$\left.\begin{array}{c}x=a\cos \left(2\mathrm{\&pi;}\right)+(2a-c)\cos \left(\mathrm{\&pi;}\right)=a\&times;1+(2a-c)\&times;(-1)=-a+c\\ y=a\sin \left(2\mathrm{\&pi;}\right)+(2a-c)\sin \left(\mathrm{\&pi;}\right)=a\&times;\left(0\right)+(2a-c)\&times;0=0\end{array}\right\}...\left(16\right)$

Track at a pair of ora terminalis of clamp-oning as shown in figure 20 plate 26 becomes crossed loops 29d, when connection is clamp-oned the direction of a pair of ora terminalis of plate 26 and the bearing of trend of dividing plate 21 when consistent, the lower end of stationary barrier 21 and clamp-on gap between the surface of plate 26 and be so great that and exceed needs.That is to say, in the time comparing with the situation of above-mentioned b=2a, can produce redundantly the gap beta (β=W/2 in Figure 20) causing because of the portion of reporting to the leadship after accomplishing a task of crossed loops 29d in Figure 20.For guaranteeing intensity, need to clamp-on plate 26 and there is certain thickness W, but can not be too little, there is a limit.Track at the ora terminalis of clamp-oning plate 26 becomes crossed loops 29d, for example, because from the below extended line of dividing plate 21, (in Figure 20 on x axle) moves to rubbish and drops into the ora terminalis of clamp-oning plate 26 of spatial portion 6d mono-side (region below x axle in Figure 20) at the beginning, can increase on one side at once afterwards the gap between itself and dividing plate 21, again for example, towards rubbish container case 3 one sides (region more than x axle in Figure 20) mobile from the below extended line of dividing plate 21 on one side, the problem that exists rubbish easily to be bitten.Hence one can see that, and it has been exactly a large problem that the portion of reporting to the leadship after accomplishing a task of crossed loops 29d can cause producing gap beta.

As mentioned above, the relation of formula (13) is set up and is belonged to ideal situation.But in reality, clamp-on plate 26 and can have scale error and manufacturing errors δ.Therefore, in the present embodiment, as shown in figure 18, with regard to clamp-oning plate 26, offset a from the centre of gration of rotating bearing component 22 to rotating shaft 25, clamp-on distance (total length) L thickness W, a pair of ora terminalis of plate 26 ₀, and the relation of clamp-oning between size and the manufacturing errors δ of plate 26 meet following formula (17).

L ₀＝4a+W+δ…(17)

Size and manufacturing errors δ are likely produce in normal Fabrication procedure so large, and formula has allowed some errors in (17).

Set the position of dividing plate 21 lower end 21c, so that the distance L from this lower end 21c to centre of gration ₁, relation between offset a, thickness W, gap α, the size of clamp-oning plate 26 and manufacturing errors δ meets following formula (18).

$L_1=a+\frac{W}{2}+\mathrm{\&delta;}+\mathrm{\&alpha;}...\left(18\right)$

Here, make gap α be the lower end 21c of metal part processed of dividing plate 21 with the metal control surface of clamp-oning plate 26 relative to moving smoothly, and considered the scale error of component parts, as the specified value after the minimum diameter of the rubbish of object.For example this gap α is set as to 0mm < α≤50mm, is preferably set to 2mm≤α≤20mm.In addition, exactly in the situation that having formed gap α, the bottom 21b by the metal part processed at dividing plate 21 installs sealing member, also can essence eliminate dividing plate 21 metal part processed lower end 21c and clamp-on the gap between plate 26 metal control surface 26a.

In the present embodiment, a relative effects on surface 26a on thickness direction who clamp-ons plate 26 looks and is respectively arcuation from the axis direction of rotating shaft 25, but this surperficial shape is determined by following relational expression.

That is to say, the surperficial 26a relative with dividing plate 21 that clamp-on plate 26 be upper, point from the straight line by the lower end 21c of connecting partition 21 and the centre of gration of rotating bearing component 22 is to the distance L when this centre of gration ₂always meet formula and form the surperficial 26a shape of clamp-oning plate 26 (3), with the irrelevant to rotation of clamp-oning plate 26, so, even if clamp-oning the surperficial 26a of plate 26 does not form very smoothly, and have bending part at the plate-shaped member 40,41 that forms surperficial 26a, can not produce the gap that exceeds needs yet.

O＜L ₂≤L1…(19)

From the above, ideal situation be form clamp-on plate 26 with ensure from the centre of gration of rotating bearing component 22 to clamp-on plate 26 rotating shaft 25 axle center offset a, meet b >=2a from the axle center of this rotating shaft 25 to the relation of clamp-oning the distance b of one end of plate 26.By keeping this relation, just can avoid the track of a pair of ora terminalis of clamp-oning plate 26 to become the crossed loops 29d shown in Figure 20.So, can prevent from clamp-oning plate 26 understand increase above-mentioned excessive gap beta, aggravation rubbish bitten such action.Consequently, can become and suitably formed the lower end of dividing plate 21 and clamp-oned the refuse collector in the gap between plate 26.

Then, though details do not show, but the integral structure of refuse collector 1 is explained.Refuse collector 1 comprises the electrical generator being driven by vehicle motor, is configured to: the electric power obtaining at this electrical generator or the electric power of savings in electrical storage device are supplied with electro-motor 56.The hydraulic circuit 61 of the hydraulic efficiency gear 60 of refuse collector 1 has been shown in Fig. 6.Hydraulic efficiency gear 60 comprises the Hydraulic Pump 47 being driven by electro-motor 56, is configured to: the working oil in operating oil tank 62, after conduit under fluid pressure 64 is drunk up by Hydraulic Pump 57, flows in the conduit under fluid pressure 61a of supply side, is supplied to control cock 63.Each cylinder 9,12 and CD-ROM drive motor 14 are connected in control cock 63 through conduit under fluid pressure 61b.Control cock 63 comprises multiple not shown electromagnetic valves, is configured to: the switch mouth by switching solenoid valve will feed to cylinder 9,12 or the CD-ROM drive motor 14 expected from the working oil that is driven the Hydraulic Pump 57 of rotation to spray by electro-motor 56.Rotate by switching and CD-ROM drive motor 14 that control cock 63 is controlled the expanding-contracting action of cylinder 9,12 thus, or running is stopped by control cock 63.In addition, the execution unit that the refuse collector 1 of present embodiment is worked in the time carrying out the loading operation of rubbish is only a CD-ROM drive motor 14, therefore the board-like refuse collector of common compression, rotate board-like refuse collector needed multiple execution units in the time carrying out rubbish loading operation, in the refuse collector 1 of present embodiment, be N/R.

-collection method of refuse collector to rubbish-

First, refuse collector 1 is moved to rubbish 55 and collect ground, open input port 7.

Then, as shown in Figure 7, the surperficial 26a part of the length direction central part of clamp-oning plate 26 of seeing from axis direction approaches the lower end 21c of dividing plate 21, and near the state that an ora terminalis clamp-oning plate 26 is positioned at the inside one side of wall 6c is readiness for action.Under this readiness for action, because the below of dividing plate 21 is plugged, so the rubbish 55 being squeezed in rubbish container case 3 can not drop into case 6 one sides refluences towards rubbish again.And, under this state, rubbish 55 is invested to rubbish and drop into the below that plate 26 is clamp-oned in the bottom of spatial portion 6d.Now, the board-like refuse collector of the rotation certain from rotating shaft position is different, the rotating shaft 25 of clamp-oning plate 26 while dropping into rubbish 55 is towards rubbish container case 3 one side shiftings, clamp-on plate 26 and can be positioned at the position away from input port 7, so the size of the rubbish that this refuse collector 1 can be collected is greater than the rubbish that the board-like refuse collector of rotation can be collected.And, clamp-on the track of plate 26 by adjusting the base of input port 7 is set lowlyer, so rubbish 55 is easy to drop into.

Then, allow after CD-ROM drive motor 14 rotation, rotating bearing component 22 just press clockwise direction rotation in Fig. 7, is clamp-oning under the effect of speed reduction gearing 27 of plate use, clamp-ons plate 26 and rotates in the direction of the clock with 1/2 speed of rotating bearing component 22.So, as shown in Fig. 8 and Fig. 9, clamp-on plate 26 towards input port 7 one sideway swivels.Now because roughly the recess 29a of cardioid 29 and the lower end 21c of dividing plate 21 basically identical, so be difficult at lower end 21c and clamp-on between the surperficial 26a of plate 26 rubbish 55 is bitten.And ridge 33 is according to rubbish 55, this rubbish 55 just can be near lower end 21c, so can further effectively prevent that rubbish 55 from being bitten.

In the time clamp-oning plate 26 and be further rotated, as shown in Figures 10 and 11, rubbish 55 is extruded in rubbish container case 3 from rear peristome 4 by the below of the lower end 21c of dividing plate 21 reliably by ridge 33.Now, form the mode that rubbish drops into the wall 6c of the bottom of spatial portion 6d and move to approach because clamp-on plate 26 and ridge 33, so although only clamp-oning plate 26 is rotating, clamp-on plate 26 and also can give play to the function of compressed garbage 55.

On the one hand, when clamp-oning plate 26 rotations, the lower end 21c of dividing plate 21 and clamp-on the surperficial 26a landfill that gap between plate 26 can squeezed entering plate 26, on the other hand, allow like this ridge 33 from clamp-on the each surperficial 26a of plate 26 outstanding after, the rubbish 55 that can make to be once once pressed against rubbish container case 3 one sides becomes is being pressed by ridge 33 and is floating from clamp-oning the surperficial 26a of plate 26 state coming.Because ridge 33 is in the interior movement of notch 34 of dividing plate 21, so even if ridge 33 more can not hinder more yet and clamp-on plate 26 and rotate.

Then, clamp-on plate 26 and rotate 1/2 week, return to the state shown in Fig. 7, stress the multiple operation starting from Fig. 7 at the surperficial 26a mono-of a contrary side.

And have for clamp-on rubbish 55 clamp-on plate and in order to compared with the board-like refuse collector of common rotation of the swivel mount of the rubbish 55 of putting together, present embodiment is clamp-oned plate 26 with one and just can have been given play to closing functions and clamp-on function, so can reduce the quantity of the execution units such as hydraulic cylinder.After the quantity of execution unit reduces, the weight of device will alleviate, and after the weight saving of device, just can correspondingly increase stowage capacity.

In addition, up to the present the board-like refuse collector of common rotation loads rubbish 55 by clamp-oning these two parts of plate and swivel mount, but so-called planetary rotation is clamp-oned board-like refuse collector 1 in the present embodiment, only clamp-on plate 26 with one and load rubbish 55, therefore compared with the board-like refuse collector of rotation, the rotative speed that can make to clamp-on plate 26 in an operating turnaround is slower.And, clamp-on in board-like refuse collector 1 at the so-called planetary rotation of present embodiment, do not deposit the upset down maneuver of compressing in the prior art board-like refuse collector, the action of clamp-oning of clamp-oning plate of rotating board-like refuse collector, so can not produce standby time in the loading operation of rubbish 55 yet.

That in present embodiment, leans on only rotatablely moves, thus with use the compression of cylinder board-like, rotate compared with board-like refuse collector, the planetary rotation in present embodiment is clamp-oned board-like refuse collector 1 and is had the following advantages: impact less, noise is low; In loading operation, there is no the switching of electromagnetic valve, therefore noise is low, excellent in efficiency; Do not need to carry out without the complex control such as impulsive control, switching controls.

Therefore,, with preventing that once simple structure rubbish 55 from flowing backwards and being bitten on one side, efficiency is clamp-oned rubbish 55 in rubbish container case 3 well on one side.

The present invention can also adopt following structure in the above-described embodiment.

That is to say, shown in above-mentioned embodiment is that refuse collector is arranged on to the example on electric garbage collection car 1, but this refuse collector fixedly can also be set on the ground of building, factory etc.Particularly, not that refuse collector is arranged on to body shell 2b above, be arranged on ground framework and be arranged on.

In the above-described embodiment, the shape of clamp-oning plate 26 is mainly by form polylith plate-shaped member 40,41 welded joint together.But can also tabular polylith part bonding be got up to form the shape of clamp-oning plate with rivet.

Also can there is tubing in the location arrangements of the central part that becomes a pair of ora terminalis of clamp-oning plate, with plate-shaped member, they are joined together to form and clamp-on plate.

In the above-described embodiment, be formed with multiple edges and clamp-on the axially extended bending part 41a of plate 26 at plate-shaped member 40,41, but bending part is not set but the surface that makes to clamp-on plate is formed as level and smooth curved surface is also fine.

In the above-described embodiment, drive the mechanism that clamp-ons plate 26 to be formed by chain mechanism, clamp-on plate but gear directly can also be linked up mutually to drive.

In the above-described embodiment, show the example with the refuse collector 1 of electrical motor driven Hydraulic Pump, but refuse collector can also not adopt the method with electrical motor driven Hydraulic Pump, and adopt the method that through power acquisition device (PTO), the propulsive effort of driving engine is passed to Hydraulic Pump.In the present embodiment, be to make the dynamic retarding of the CD-ROM drive motor 14 of hydraulic pressure drive rotating bearing component 22, but can also use the power of electro-motor 46.Propulsion source to this CD-ROM drive motor 14, electro-motor 46 also has no particular limits.
