Abstract
Description
- The invention relates to a loading mechanism for a refuse vehicle whereby the rear opening extends substantially vertically between the floor and the sidewalls of the body of the refuse vehicle. In particular, reference is made to a loading mechanism for a rear- loading refuse vehicle, e.g. for removing household waste.
- Loading mechanisms of this kind are widely known and are often hingedly mounted on a horizontal spindle at the top of the rear opening of the refuse vehicle body. Sometimes the loading mechanisms share a fixed partition wall with the uppermost part of the rear opening in the refuse vehicle body, as well as a slide member which can move up and down and at whose bottomJ hinges are provided for a pivotable packer blade which, in a known manner, coacts with the, possibly curved, floor of the refuse receiver or hopper for any necessary compressing and dumping of the waste into the refuse vehicle body.
- It is also known to guide the reciprocating-slide member carrying the packer blade by sliding it in its tracks near the sidewalls of the hopper. The sliding movement is then achieved by driving means, such as hydraulic cylinder-piston combinations attached to these sidewalls and connected to the slide member.
- In order to simplify the construction of these driving means and to increase their efficiency, it is now suggested to mount them between the fixed partition wall and the slide member and to connect them fixedly to the partition wall near its bottomside, while the moving part of the driving means is connected to the upper side of the slide member.
- Further characteristics of the loading mechanism according to the invention will be further clarified hereafter with reference to an embodiment shown in the adjoined figures.
-
- Figure 1 is a cross sectional view of the loading mechanism connected to the refuse vehicle ;
- Figure 2 is a detailed view of the adjustable guiding means for the slide member in the sidewalls of the loading mechanism.
- The rear portion of a refuse vehicle shown in Figure 1 comprises the
refuse body 1 withrear opening 2 above which theloading mechanism 4 is pivotably fixed inhinge 3. - When the
refuse vehicle 1 is being loaded, the loading mechanism rests with itssidewalls 5 against therear opening 2 and with its underside orfloor 6 against theextention plate 7 which at the bottom of therear opening 2 is attached to thefloor 8 of the refuse vehicle. Thesidewalls 5 at both sides of the loading mechanism are connected to each other by apartition wall 9 which with its horizontal underedge connects 10 with a crossbeamY. On this crossbeam, halfway between the sidewalls, a hydraulic cylinder-piston pressure combination 11, 12 is mounted as driving means, which preferably extends parallel to theslide member 13. In 14 the upperend of the piston rod is connected to the middle of the upperside of the slide member. Hence, by means of the hydraulic pressure means 11, 12 theslide member 13 is able to move up and down and in this process it is guided in suitableelongated slots 15 in bothsidewalls 5 by means of the guidingmeans 16 described further on. At the bottom of the slide member thepacker blade 17 is pivotably bearing-mounted in a known manner aboutrod 18. The rotation is also performed by a hydraulic cylinder 19 which has asupport 20 in the framework of the slide member and whosepiston rod 21 is hingedly attached to an extension piece 22 of the packer blade. - The working cycle of the loading mechanism is as follows. We assume that the slide member is in its upper position and the packer blade is in open position 23 (dotted line). The refuse to be loaded is dumped into
space 24 onfloor 6 of the hopper and the slide member with openedpacker blade 23 is slid downwards under the influence of the hydraulic pressure means 11, 12 until the packer blade reachesposition 17. The cylinder 19 is now brought into operation and theplate 17 pivots around therod 18 into itsposition 25. During this pivoting movement theplate 17 coacts with thefloor 6 for compressing the dumped material and shoves it further on towards the reax-:opening 2. The cylinder 19 keeps its position and theslide member 13 is incoupling 14 again pushed upwards into itsupper position 26 by pressure means 11- 12. The packer blade so pushes the dumped material further upwards into the rear opening between theslide member wall 28 and theextension plate 7 towards itsposition 27. - The operation of this loading mechanism permits the use of but one
hydraulic pressure cylinder 11 or a similar driving means for the slide member. This simplifies the hydraulic pressure circuit, lowers the weight and the cost of the loading mechanism, as well as the risk of defect of the hydraulic circuit or the pressure cylinders. The position ofcylinder 11 withfixed support 10 at the bottom also raises the pressure efficiency since the cylinder must exert most force exactly when it must push the slide member and the packer blade (traject frompositions 25 to 27) carrying the material to be moved upwards. Theentire piston surface 29 is used for this upward movement (without reduction of the piston rod cross section). Moreover, with the position ofcylinder 11 between thepartition wall 9 and theslide member 13 there is less wear of the guidingslots 15 when the slide member is moved upwards than when the cylinder would have been located on the other side of the slide member. Indeed a smaller couple is formed by the guidingmeans 16 in theslots 15. - In order, on the one hand, to further reduce the frictional wear of the
means 16 in the slots, and, on the other hand, to avoid extremely strict and hardly applicable construction tolerances for theslots 15, the invention suggests as an additional measure to make the guiding means 16 horizontally adjustable. Moreover, these guiding means preferably comprise friction blocks in combination with roller guides as sliding mechanisms as will be described further on with reference to the detailed drawing in Figure 2. - Said figure shows one of the upper corners of the
slide member 13 as viewed from the rear side of the refuse vehicle and moving up and down along the inner side 31 of thesidewall 5 of the loading mechanism. The movement of the slide member inslot 15 is guided by guidingmeans 16 fixed to theupper edge 32 of the slide member. These guiding means 16 essentially comprise abearing block 33 to whose end, extending in theslot 15, arectangular friction block 34 is fixed and which comprises asliding plate 35 e.g. made of bronze. The friction block 34 - 35 preferably slides against thewalls slot 15. Aroller guide 36 is bearing mounted on this shaft end and normally rolls against the bottomtransverse surface 30 of theslot 15. Thebearing block 33 together with this guidingcombination sidewall 5. This offers the exceptional advantage that in case of frictional wear, particularly on theinner side 37 of thesidewall 5, the resulting play between the guiding means andwall 37 can be reduced. This is important since it is known by experience that increasing play in the slide member guiding slots leads to faster wear therein and on an average also requires more sliding energy. Moreover, chances increase that the guiding means 16 blocks in case of unequal loading on the packer blade across the width of the loading mechanism. - The
bearing block 33 is fixed to theupper side 32 of the slide member by means of bolt-nut connections 38 thereby using anintermediate clamping plate 39 and throughsuitable bores 40 inblock 33. The bores have a elongated cross section with the greater transverse dimension in the direction perpendicular to thesidewall 5 so that a displacement of the bearing block in that direction becomes possible after that thebolts 38 have been 'slightly released. The displacement distance can be set by means of thenuts 41 against thestop 42 fixed to the upperside of the slide member. - The invention is not limited to the embodiment of the loading mechanism herein described and illustrated. For example the
partition plate 9 may be convexed (dottedline 43 in Figure 1) in the direction of the rear opening of the refuse body in order to stimulate the compressing process in the rear opening. Theslot walls roller 36 may also be replaced by a sliding block, for example made of bronze.Cylinder 11 can also be positioned not parallel with theslide member 13.
