Abstract
Description
- The present invention relates to a vehicle for the loading, compacting and discharge of refuse.
- More specifically, the invention relates to a vehicle of the type including:
- a load-carrying body which is carried by the structure of the vehicle and has a top wall and a bottom wall connected by a pair of side walls and a front wall, the body also having an opening at its rear for the loading and discharge of the refuse,
- a first longitudinal guide adjacent the top wall and a second guide parallel to and below said first guide, each guide being constituted by a pair of tracks fixed to the body,
- a plate for discharging the refuse, the plate being movable within the body between a first position adjacent the front wall and a second position in which it is in correspondence with the rear opening, and having first and second engagement means which connect it slidably to the first and second guides, respectively, and
- actuator means for moving the plate between its first and second positions.
- A vehicle of the type specified above is known from the present Applicant's Italian utility model application No. 52883-B/81. This document describes a vehicle with a body which has upper and lower guides on which a movable plate is slidable. The bottom wall of the body has an upwardly curved end portion so that the vehicle can transfer the refuse into the body of a larger vehicle whose load opening is at a greater height. The lower guide extends along the entire length of the bottom wall as far as the rear opening. The movable plate is permanently engaged on both the guides and, during the expulsion of the refuse, pivots upwardly by virtue of the curvature of the lower guide.
- In order to provide a vehicle which is simpler and more reliable than the known vehicle described above, the subject of the present invention is a vehicle of the type specified at the beginning, characterised in that the first longitudinal guide has a stop near its rear end, in that the rear end of the second guide is further forward than the rear end of the first guide and in that, when displaced in the rearward direction, the second engagement means can be disengaged from the second guide after passing said rear end of said second guide so that the movement of the movable plate towards its second position causes the second engagement means to be disengaged from the second guide when the first engagement means contact the stop on the first guide, the further operation of the actuator means thus causing the movable plate to pivot about a transverse axis which passes through the end-of-travel position of the first engagement means.
- Translatory and rotatory movements of the movable plate can thus be achieved simply by rectilinear guides which do not need to be produced with particular accuracy.
- In a preferred embodiment, the discharge plate is inclined to the vertical with its lower edged further forward than its upper edge and, adjacent the rear opening, the bottom wall of the body has an end portion with the profile of an arc of a circle the centre of which coincides substantially with the axis about which the movable plate pivots, the end portion being at least partially recessed relative to the rest of the bottom wall. By virtue of this characteristic, the discharge edge of the rear opening can be kept at a lower level which facilitates the manual loading of the refuse.
- The vehicle according to the invention preferably includes a panel articulated to the rear loading edge of the body, and having a profile corresponding to that of the end portion of the bottom wall. When the contents of the body are to be transferred into the body of a larger vehicle, the panel is raised to form an extension of the bottom wall. The loading edge is thus raised to the level of the loading edge of the larger vehicle.
- Further characteristics and advantages of the present invention will become clear in the course of the detailed description which follows with reference to the appended drawings in which Figures 1, 2 and 3 are schematic sections showing the operating sequence of the vehicle according to the invention.
- With reference to the drawings, a vehicle for the loading, compacting and discharge of refuse is indicated 1. The vehicle 1 has a body 2 which is fixed to the structure of the vehicle. The body 2 is constituted essentially by a
bottom wall 4, a top wall, a pair ofside walls 8, and afront wall 10. An opening at the rear, through which the refuse is loaded into the body and discharged in the manner which will be described below, is indicated 12. - The body 2 has a pair of
guides guide respective side walls 8 of the body 2. - Within the body 2 is a
movable plate 20 which is carried by asupport structure 22 with a right-angled triangular cross-section. The base of thetriangular structure 22 is slidable on theguides rollers structure 22. - The rear end of the
upper guide 14 has astop 28 which therollers 24 running on the tracks constituting theupper guide 14 are intended to abut. The rear end of thelower guide 16 is further forward than the rear end of theupper guide 14. The distance between the rear ends of the upper andlower guides front rollers front rollers 26 can be disengaged from thelower guide 16 when the rear rollers contact thestop 28. The rear end of thelower guide 16 has a lead-inportion 30, the function of which will become clear from the following. - The
structure 22 is made to slide along theguides hydraulic cylinder 32. The body of thecylinder 32 is articulated to thestructure 22 at 34 and theend 36 of thecylinder 32 is articulated to the body 2 at 36. - Outside the body 2 is a
compacting device 38 including a pair of arms 40 (only one of which is visible in the drawings) which are articulated to the top wall of the body 2 at 42. A hollowcompacting plate 44, in which aplate 50 is slidable telescopically, is articulated to the free ends of thearms 40. Thearms 40 are operated by a pair of hydraulic cylinders 46 which are articulated on theside walls 8 of the body 2. A hydraulic cylinder 48 (see Figure 2) is interposed between the top wall of the body and thecompacting plate 44. A hydraulic cylinder, not visible in the drawings, is disposed in the compacting plate 41 and controls the sliding of thetelescopic plate 50. - The
bottom wall 4 of the body 2 has anend portion 52 with the profile of an arc of a circle the centre of which lies in correspondence with the rear end of theupper guide 14. Theend portion 52 is recessed relative to the rest of thebottom wall 4. This geometry reduces the height of the loading edge of therear opening 12, thus facilitating the loading of the refuse into the body 2. A panel, indicated 54, which can be lowered is articulated to the body 2 in correspondence with the loading edge of therear opening 12. In order to transfer the refuse in the body 2 into the body of a larger vehicle, thepanel 54 is brought to the position shown in Figure 3 so as to raise the lower edge of theopening 12 and bring it to the same height as the loading edge of the larger body. The profile of thepanel 54 corresponds to that of theend portion 52 of thebottom wall 4. - In Figure 1, the vehicle 1 is in the loading position. The
movable plate 20 is at the rear end of theguide 14 and theplate 50 is within thecompacting plate 44 so as not to obstruct the loading of the refuse through therear opening 12. A loading device of known type (not shown) at the rear end of the body 2 picks up a container of refuse and tips its contents into the body 2 through therear opening 12. - Figure 2 shows the operating sequence of the
compacting device 38. Thesliding plate 50 is first extended and the compactingplate 44 is then pivoted by means of thehydraulic cylinder 48. The operating cycle of the compacting device is described in greater detail in the Italian patent application No. TO91AOOO359 by the present applicant. - As the refuse is gradually compressed in the body 2 by the
compacting device 38, themovable plate 20 moves towards the front end of the body, against a reacting force generated by thecylinder 32, until it is brought against thefront wall 10 as shown in Figure 2. - When the body 2 is full, the refuse is discharged by the operation of the
multi-sectioned cylinder 32 which slides thestructure 22 carrying theplate 20. When therear rollers 24 contact thestop 28 on theupper guide 14, thefront rollers 26 are disengaged from thelower guide 16. The further operation of thecylinder 32 causes thestructure 22 to pivot about a transverse axis which passes through the pins of therollers 24 until it reaches the position shown in Figure 3. It will be understood from an observation of the pivoting movement performed by theplate 20, that the profile of theend portion 52 of thebottom wall 4 is recessed because of the need to allow for the pivoting of theplate 20 which, in the loading position shown in Figures 1 and 2, is inclined to the vertical with its lower edge further forward than its upper edge. The purpose of the lead-in 30 at the rear end of thelower guide 16 is to return therollers 26 into engagement with theguide 16 when thestructure 22 is retracted. - When the contents of the body 2 have to be discharged into the body of a larger vehicle, the
panel 54 is raised to the position shown in Figure 4 and thecylinder 32 continues to be operated until the lower edge of theplate 20 is in correspondence with the end of thepanel 54.
