Definitions

  • This invention relates to a truck for the collection of garbage and refuse of the type comprising a load-containing body having adjacent the rear open end thereof a hopper pivotally connected thereto at the top portion thereof and provided with means for lifting garbage containers, discharging the contents of the latter into said hopper by upturning them and have the empty containers lowered by means of a rack and pinion device (as in GB-A-1399454) and which container lifting, upturning and lowering stages are carried out at different speed (as in US-A-5007786), and feeding the contents into the said truck load body.
  • the body comprises an ejector press for discharging the garbage and refuse contained therein.
  • the problem of the environmental impact is solved by suitably enclosing the bodywork and the hopper with smooth plates which may be decorated as desired. These plates are complemented with further smaller lower plates covering the lower portion of the chassis sides and some of them are openable to allow access, for example, to the fuel tank, to the spare wheels and to the batteries.
  • Yet another improvement of the invention consists of the fitting of joint bushings in the joints of the hydraulic cylinders with which different devices and mechanisms of the truck are operated. This prevents said joints from working under stress, with the risk of breakage.
  • Yet another of the features is the presence in the cab of a light and acoustic control panel for the different operations to be carried out, mainly the different stages of loading.
  • these controls there is a main switch and a changeover switch for selecting an intermittent or continuous working cycle.
  • This truck also comprises a hydraulic system whereby it is possible to compact the garbage in the load-containing body, without this depending on the working section of the telescopic cylinder operating the ejector press.
  • the hydraulic system prevents the forward feed of the press unless the hopper is raised.
  • the truck for collecting garbage and refuse shown comprises, in the rear open end of the hopper 1, the assembly 2 which takes hold of and lifts the garbage containers, said assembly being vertically moveable between the two open facing tubular columns 3 disposed at either side of said open end.
  • the assembly 2 is fixedly attached at both sides on corresponding sleeves 4 which, in turn, are mounted over respective shafts 5 ( Figure 3) which are coupled and fixed at one end to an intermediate shaft 5' and at the other end to respective sliding shoes 6 which run on corresponding U-shaped guide ways 7 fixedly attached vertically to the inside of the columns 3.
  • Each sliding shoe 6 is formed by a block 6' having a respective side plate 6'' fixed thereto and which slide on the guide way 7, said blocks also having attached thereto a vertical stem 8, terminated with a flaglike plate 8' which, when the assembly 2 is moved upwards by the action of two hydraulic cylinders 9 attached to said blocks 6' and which are coupled to respective supports 10 separably attached to ones or others of holes 11' formed in plates 11 attached to the upper portion of the columns 3, pass by two sensors 12 and 12' installed thereon and which provide the different speeds in the various lifting and upturning stages of the assembly 2.
  • the assembly 2 is provided with a sensor 15 of the type which adapts the different speeds of lifting, upturning and lowering to the features of the garbage container or containers to be unloaded, it also being possible to program such speeds at will.
  • the arms 16 of said assembly 2 for engaging the garbage containers by their side handles are provided to such end with two links 17, 18, with respective upper fingers 17', 18' retaining such handles by the ends thereof.
  • the open end of the truck body also has pivotally mounted thereto at the top on both sides of the cross member 19, respective arms 22 terminated in a hook 22' for opening the lid T of the garbage containers C as required, said arms 22 being moved to the rest position thereof by respective gas springs 23, also pivotally mounted to the said open end of the truck body.
  • the hopper 1 is pivotally mounted at the top to the rear open end of the body 24 by respective side stubs 25 which are inserted in corresponding vertical elongate holes 26 of lugs 27 mounted on the side of the top portion of the said open end of the body 24, the hopper 1 being lifted for unloading the truck by the action of two external side hydraulic cylinders 28, pivotably attached thereto and to the body 24 and after they have released said hopper from the closed position thereof, which is achieved by raising respective lower side stubs 29 which are engaged in respective forks 30 of the lower portion of the side members of the upper open end of the body 24 ( Figure 5).
  • the body 24 is formed by four arcuate plates 37 forming the roof, the bottom and the side walls and which are attached to the front and rear frames 38 and 39, the concave surface of said plates 37 facing the inside of the body 24, the latter being externally reinforced longitudinally with two pairs of sections 40 occupying the upper and lower portions of the side members.
  • the load-containing body 24 has attached to the interior thereof, on the lower sheet 37 forming the bottom a longitudinal central I section 41 forming the guide railfor the ejector press 42 ( Figure 9) when moving.
  • the said press 42 has fixedly attached thereto, under the frame 42' forming the base thereof, two U-shaped longitudinal sections 43 the open sides of which face each other, the corresponding ends of a further two inverted L-shaped sections 44 being fixedly attached to the intermediate and lower portions of the former sections.
  • the latter form in the sections 43 two tubular members which, when inserted in the sides of the section 41, support at the top and the bottom respective sliding shoes 45 for sliding along the inner surfaces of the flanges and web of said section 41.
  • the sliding shoes 45 are longitudinally locked against the sections 43 and 44 by covers 46 which are attached with screws 47 to plates 48 fixedly attached at the ends of the tubular members forming the said sections 43, 44, with the said covers extending out from the members at the top and at the bottom.
  • covers 46 have the upper and lower edges thereof provided with respective lips 46' which engage in corresponding steps 45' of the sliding shoes 45 and grip them with intermediate teeth 46" preventing lateral movement ( Figure 11).
  • the ejection press 42 guiding is complemented with a further longitudinal central tubular guide member 47 fixedly attached to the metal sheet 37 forming the roof of the body 24 which is engaged by two sliding shoes 48 which slide therealong and are attached to the vertical portions of a U-shaped section 49 fixed in turn to a support 50 fixedly attached in the centre to the upper portion of the ejector press 42.
  • the majority of the hydraulic cylinders with which the various truck mechanisms are driven are attached to the mechanisms by a joint bushing 51 retained by the pertinent end 54 of the cylinder, with a friction washer 54'.
  • Said joint bushing 51 is mounted around the pivoting shaft 52 retained at the ends thereof in two forked wings 53 provided in the pertinent device.
  • the body 24 and the hopper 1 have the respective external side walls thereof faired with respective plates 55 and 56 which are smooth on the outside and are reinforced on the inside with metal straps 59, said plates being provided at the top and bottom thereof with corresponding longitudinal flanges 57 projecting to the inside thereof and provided with holes 58 for attachment, by bolts, to the said body 24 and hopper 1, after the said plates 55 and 56 have been engaged behind respective flanges 60 fixedly attached to the frame 39 and the columns 3, the plates 56 also comprising a trap 56' for access to certain parts thereof, with all the plates 55 and 56 being extended at the bottom edge thereof with a number of plates 61 which cover the truck chassis and the lower portion of the hopper, some of said plates 61 being openable for the necessary access to certain parts of the said chassis.
  • the truck is provided in the cab 62 with a control panel 63 for the operations to be carried out thereby and a monitor 64' connected to a camera 65 installed at the open end of the hopper 1, said panel comprising a main switch 66 for said operations, a control 67 so that each work cycle may be carried out continuously or intermittently, respective warning lights 68 for control thereof and, among others, warning lights 69 for controlling the different stages of the work cycle, the emergency stop indicator light 70 and the hopper raised indicator light 71.
  • the truck hydraulic system has also been provided with the valve 72 which makes it possible for the retaining or precompacting of the garbage against the ejector press to depend on the cylinders 73 which cause the carriage carrying the compacting blade, driving in turn the ejector press to eject the garbage from the body, to be moved only when the hopper 1 is raised, since the valve 74, driving the ejector press cylinder 75 depends on the elevating cylinders 28 of said hopper.
