Definitions

  • the present invention relates to a trash collecton truck with a feeder or scoop for transferring the trash from the charging container into a collector.
  • Fig. 1 represents a side view of a trash collecting truck according to the invention, the charging container into which the trash is unloaded and the collector occupying their position for receiving trash.
  • Fig. 2 is a side view similar to that of Fig. 1 but showing the charging container and the collector in lifted position for discharging the collected trash.
  • Fig. 3 shows on a somewhat larger scale than that of Figs. 1 and 2 a longitudinal section through the charging container and cooperating bucket and scoop members, said section being taken along the line IIIIII of Fig. 8.
  • Fig. 4 is a section similar to that of Fig. 3 but taken along the line IVIV of Fig. 8 and showing the bucket and scoop members in a position different from that occupied by the same in Fig. 3.
  • Figs. 5, 6 and 7 represent sections similar to those of Figs. 3 and4 but showing different phases of operation.
  • Fig. 8 is a section along the line VIII-VIII of Fig. 7.
  • Fig. 9 is a diagrammatic representation of the control mechanism for hydraulically operated cylinder piston systems arranged to actuate the charging bucket and transferring scoop for the trash receiving and transferring means.
  • Fig. 10 is a partial section taken along the line XX of Fig. 9.
  • the trash transfer arrangement for transferring the trash from the charging or receiving container to the collector is characterized primarily by two tiltable buckets or scoops each of which is tiltable about a horizontal axis.
  • the lower one of the said two buckets or scoops forms part of the receiving container and simultaneously serves as the bottom thereof.
  • the invention consists primarily in that the second bucket or scoop is tiltable about an axis at the upper end of the connecting opening between the receiving container and the collector, and following the lifting movement of the first bucket or scoop compresses .the trash into the collector.
  • the trash transfer arrangement according to the invention is furthermore characterized in that the second scoop or bucket holds back the trash transferred into the collector until additional trash is to be transferred into the collector.
  • the lower bucket or scoop is designed as receiving bucket
  • the receiving bucket' is intended first to receive the trash from the trash cans being emptied. To this end, it is desirable that the receiving bucket will during the emptying of the can occupy a rather low position so that the trash cans will not'have to be lifted too high.
  • the further task of the receiving bucket consists in that it must lift the received trash to a level from where the trash can properly be conveyed into the trash collecting chamber henceforth called trash collector, by means of a second bucket or scoop. It has proved advantageous to arrange the tilting axis of the receiving bucket some what above the bottom of the trash collector so that the trash will find a proper rest at the rear end of the trash collector and will not drop back into the receiving container when the upperbucket or scoop is tilted back.
  • a particularly compact design of the receiving container and the feeding mechanism is obtained when the axes of the two buckets or scoops are completely or nearly vertically located above each other.
  • the upper axis is expedientlyarranged approximately at the level of the upper edge of the trash collector.
  • lection truck comprises in customary manner a cab .1 and a collector 2 which is open at the rear side only.
  • the rear endof the collector supports the charging or receiving container 3 into which the trash cans are emptied.
  • the receiving container 3 is tiltably journalled about an upper axis defined by the studs 4.
  • a receiving or charging bucket 5 which is tiltable about a lower horizontal axis defined by the studs 6.
  • Fig. 2 shows the collector 2 tilted about the axis 10 at the rear of the chassis 9.
  • the tilting of the collector 2 is efiected by a hydraulically operable cylinder piston assembly 11'. It will be obvious that when the collector is tilted from Fig. 1 into Fig. 2 position, the trash slides toward the rear.
  • a tackle or cable line.12 has its front end connected to the chassis 9 and while passing over pulleys 13, 14 around the collector has its rear end connected to a point 15 of the receiving container 3 so that the latter is tilted into open position when the collector tilts about the axis defined by the stud 4 so that the trash is allowed to slide out of the collector.
  • the receiving container is illustrated on a somewhat larger scale in Fig. 3 and shows the charging bucket 5 in its lowermost position in which it is filled with trash.
  • the bucket 5 consists of two arched walls 20,21 which together with each other and the two side walls 22 (Fig.8) form a trough located between the side walls 3 of the receiving container 3.
  • the lateral walls of the charging bucket 5 are sealed with regard to the lateral walls 3 by means of felt strips 23.
  • the upper edge of the wall 21 is provided with a ledge 24, for instance of rubber or wood so that the trash can can be set down thereon when the trash can is to be emptied.
  • the cylinder 25 forming part of the cylinder piston assembly by means of which.
  • the bucket 5 is to be tilted is provided with studs 26 which are journalled in a fork 27 connected to the bucket 5.
  • the piston rod 28 is linked to the stud 30 arranged in a pocket 29 of the receiving container 3.
  • the pocket 29 forms an enlargement of a hollow beam 31.
  • Fig. 3 shows the scoop 8 in its left-hand end position in which it closes the rear portion of the collector 2 so that trash cannot drop out of the collector.
  • the scoop 8 is actuated by a cylinder piston assembly comprising the cylinder 35.
  • the cylinder is journalled about the studs 36 in a fork 37 connected to the receiving container.
  • the piston rod 38 is linked at 39 to the scoop 8.v
  • Fig. 4 shows the first phase of the trash transfer from the bucket 5 to the collector 2.
  • the scoop 8 has been tilted into its right-hand end position with regard to the drawing by the working cylinder 35, whereas the bucket. 5 filled with trash still occupies its lowermost position.
  • FIG. 5 The next phase of the trash transfer movement is illustrated in Fig. 5 accordingto which the bucket 5 has been tilted into its uppermost position by means of the working cylinder 25. During this upward movement of the bucket 5, the scoop, 8 has slipped into the bucket 5 between the outer Wall 21 and the trash in the bucket 5.
  • the next step or the trash transfer movement consists in tilting the scoop 8 from its Fig. 5 position into the Fig. 6 position.
  • the scoop 8 has pushed the trash in bucket 5 out of the latter and has pushed said trash into the collector 2 while simultaneously compacting the trash when the collector is rather filled.
  • the bottom wall 20 of the bucket 5 is arched in such a manner as to conform to the pathof movement of the tip of scoop 8.
  • the wall 40 of the hollow beam'31 is arched so as likewise to conform to the path of movement of the tip of scoop 8 on its way from the bucket 5 into the collector 2.
  • the control circuit for the working cylinders 25 and 35 is illustrated in Fig. 9 inwhich the cylinder 25 for the actuation of the bucket 5 has reciprocably mounted therein a piston 25a.
  • the cylinder 35 has reciprocably mounted therein a piston 35a for actuating the scoop 8.
  • the cylinder 25 at both sides of the piston 25a communicates with conduits 41 and 42 respectively adapted to convey a pressure fluid such as oil under pressure to and away from the piston 25a.
  • conduits 43 and 44 lead to opposite sides of the piston 35a for conveying a pressure fluid to and withdrawing a pressure fluid from piston 35a as will be described in detail later.
  • the control arrangement for use in connection with the trash transfer mechanism according to the invention furthermore comprises a casing 50 having journalled therein a control shaft 51.
  • the control shaft 51 is pro vided with two control cams 52 and 53 which are of the same design but arranged in an inverse manner with regard to each other.
  • the control shaft 51 is actuated by a hand lever 54.
  • Each of the cams 52 and 53 are in alignment with a pair of valve spools 55 and 55a respectively which respectively control the flow of fluid of passages 56 and 57 provided in casing 50.
  • a gear pump 60 withdraws oil for the working cylinders from a fluid reservoir 61 and feeds the oil through a conduit 62 into the passages 56 and 57 in casing 50.
  • the oil under pressure pumped by the gear pump 60 passes from conduit 62 through passage 56 into conduit 63 and from there through conduit 44 below the piston 35a.
  • the piston 35a is moved upwardly thereby tilting the scoop Sfrom Fig; 3 position into Fig. 4 position.
  • the cylinder 25 moves outwardly (upwardly with regard to Fig. 9) thereby tilting the bucket 5 from Fig. 4 into Fig. 5 position.
  • the lever 54 is now shifted by 180 so that the cams 52 and 53 reverse their positions.
  • the upper spool 55 is pressed downwardly (with regard to Fig. 9) by spring 70, whereas the lower spool 55 is pressed downwardly by cam 52 against the thrust of spring 71.
  • the upper spool 55a is pressed upwardly by cam 53 against the thrust of spring 72, while the lower spool 55a is pushed upwardly by spring 73. Consequently the oil under pressure from conduit 62 now.
  • the arm 64 engages and opens the check valve 66, thereby allowing escape of fluid above the piston 25:: through conduit 41, check valve 66, check valve 65, conduit 63, passage 56 and conduit 74 into the reservoir 61. Consequently the cylinder 25 now moves downwardly with regard to Fig. 9 (upwardly with regard to Fig. 6), thereby tilting the bucket 5 back into Fig. 7 position.
  • the trash transfer mechanism thus occupies again its starting position in which a new trash load can be filled into the bucket 5.
  • control cams 52 and 53 are so designed that the valve spools 55 and 55a will open the passages 56 and 57 throughout when the lever 54 is shifted by 90 only so that the oil from the control casing 50 can directly return to the reservoir 61 through the return conduit 74.
  • control shaft 51 with the cams 52, 53 and the four valve spools 55 and 55a may also be replaced by a single slide valve with correspondingly designed control channels.
  • the control by a cam shaft has been shown for purposes of clarity only.
  • a col lecting container having an opening at one end thereof, a receiving container arranged adjacent to and having a discharge opening at said one end, said receiving con tai-ner including bucket means forming the bottom of said receiving container and being tiltable about a substantially horizontal axis from its normal trash receiving position into an elevated discharge position for the transfer of trash from said receiving container into said collecting container through said discharge opening, scoop means tiltable about a substantially horizontal axis near the upper end of said discharge opening, said scoop means normally closing said discharge opening, said bucket means having two substantially parallel side walls and also having therebetween a curved front wall and a curved rear wall connected to each other along a line, the curvature of said front wall following a circle having its center of curvature located on the tilting axis of said scoop means when said bucket means occupies its discharge position, andsaid rear wall having a curvature following circle having its center of curvature located on the tilting axis of said bucket means, a curved stationary extension means extending substantially
