REFUSE HANDLING DEVICE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to refuse handling devices, and more particularly to devices of the type which receive refuse, compact it into a reduced volume, and dump the compacted refuse into a means for transporting it to a disposal site, such as a landfill location.

The need for compaction of refuse has become critical in many areas as an ecology consideration. Further, the compaction of refuse allows for more efficient handling and transportion thereof.

11. Description of the Prior Art Many devices are presently available for compacting and/or dumping compacted refuse. These devices include both portable and stationary units, and include separate units as well as combination devices. A comprehensive description of several hundred such prior art devices appears in the ninth edition of Sanitation Industry Yearbook, published by RRJ Publishing Corporation of 150 East 52nd Street, New York, NY. 10022. Additionally, related types of equipment are described in US. Pat. Nos. 3,403,620; 3,541,952; 3,554,120; 3,585,925 and 3,610,139.

The prior art devices are satisfactory to varying degrees. However, there is a continuing need for improved devices in this field.

SUMMARY OF THE INVENTION According to the present invention, a refuse handling device having advantages and improvements not previously available is provided.

Briefly, a refuse handling device in accordance with this invention has a base frame, a packer, and a selfdumping container. The self-dumping container is connected to the base frame for controlled movement with respect to both the base frame and a packer unit supported by the base frame. The packer unit and the container have matching openings such that the compacted refuse can pass from the packer into the container. I

Dumping means, preferably hydraulic rams, are provided for moving the container from a filling position to a dumping position.

The connection between the container and the base frame is such that upon initial operation of the dumping means the container moves away from the packer, and upon continued operation of the dumping means, the container pivots relative to the base frame to a dumping position.

The container includes a latchable cover to prevent the packer from forcing refuse out the dumping opening during packer operation. The cover automatically unlatches upon initial operation of the dumping means.

It is an object of the present invention to provide an improved combination refuse packer and dumper.

It is a further object to provide an improved refuse handling device including a packer unit and a selfdumping container.

The above objects as well as additional advantages are provided by the present invention as will be apparent from consideration of the following detailed description.

DESCRIPTION OF THE PREFERRED EMBODIMENT The invention will now be described in detail by reference to the several views of the drawings, which illustrate the preferred form of the invention.

As shown in FIGS. 1 5 and 9, a refuse handling device in accordance with the preferred embodiment of the invention is shown generally at 10. The device 10 includes a packer unit 1 l, a self-dumping container 12, and a base frame 13. The base frame 13 includes a pair of upstanding frame members 14 and 15 (FIG. 1).

The upstanding frame members 14 and 15 have vertically oriented slots 16, 17 formed therein respectively.

One end of each of a pair of hydraulic rams 18, 19

' is attached to base frame 13 and the other end of each ram l8, 19 is connected to the container at stiffening members 20, 21 respectively. Stiffening members 20, 21 extend beyond the forward end of container 12 (see FIGS. 1 and 3) and have pins 22, 23 respectively extending therefrom into slots 16, 17 in upstanding frame members 14 and 15.

The container 12 has a foldable door 24 which automatically is latched shut when the container is in the filling position. The door opening and latching mechanism on each side of the container is identical, so the mechanism on one side only will be described. As seen in FIG. 4, a flexible line 25 is anchored to an upstanding frame member and extends over a sheave 26 supported by the back half of door 24, then over a first latch 27 attached to the forward half of door 24, and finally to a second latch 28 pivotally connected to the forward edge of door 24 and biased in a latched position by spring 29. As best seen in FIG. 5, as the container 12 is tilted, the flexible line 25 causes second latch 28 to open away from its associated pin 30 and then pivots the forward half of the door 24 into a partially open position as shown by dotted lines in FIG. 5. Continued tilting of container 12 to the full dumping position, shown in full line in FIG. 5, opens the forward half of door 24 clear of a rear end loader 31 as seen in FIG. 9. It will be seen that the folding feature of door 24 enables the rear end loader 31 to be positioned very close to the container 12 (FIG. 9). The back half of door 24 can be opened away from the container 12 (FIG. 5) to facilitate emptying of stuck material from the container, for example. It will be appreciated that the middle latch 27 pivots away from its associated pin 32 (FIG. 5) upon opening of the forward half of door 24. Upon returning container 12 to the filling position, the door 24 closes by gravity and automatically latches in the position shown in FIG. 4. Without an automatically latching door, there would be a problem of refuse being pushed out the top of container 12 as packer unit 11 forces material into a full container. This would lead to spills, as is apparent.

The packer unit 11 includes a filling chute 33 (FIGS. 3 and 4) at the top forward portion thereof. A packing head 34 is mounted for reciprocating sliding movement within the packer unit 11 in response to extension and retraction of packing rams 35 and 36 (FIGS. 3, 4, 6 and 7). The packing rams 35 and 36 are mounted in an X configuration as seen in FIGS. 6 and 7 to reduce the overall length of the packer unit. Guide rails 41, 42 and 43 on frame 13 (FIG. 7) guide packing head 34 during the operation of packer unit 11. a

As is apparent from FIG. 3, for example, refuse 37 is fed into the packer unit when the packing head 34 is retracted. Extension of the rams 35 and 36 to the position shown in FIG. 4 then forces refuse through an outlet in the forward end of packing unit 11 into an opening at the rear of container 12 in registration with the packer opening. As seen in FIGS. 2 and 8, a flexible sealing strip 38 is provided between the packer unit and the container to minimize spillage and to reduce the noise level of the device.

As seen in FIGS. 2 5, guide pins 39 on either side of the top front of the packing unit engage pin receiving means 40 on container 12 to maintain proper alignment between the packer unit and the container.

The operation of the device will now be briefly described. The device 10 is initially charged with refuse 37 (FIG. 3). The packer unit 11 is then operated to push refuse into container 12. Repetition of the filling and packing is continued until container 12 is filled with compacted refuse. Note that during filling of container 12 the pins 22 and 23 are positioned at the bottoms of slots 16 and 17.

When the filled container is to be dumped, the dumping rams 18 and 19 are extended. Initial extension of these rams causes the pins 22 and 23 to move upwardly in slots 16 and 17 to the position shown in FIG. 4. Note that this also results in the container 12 being moved slightly away from the sealing strip 38 around the packer outlet opening. This can be seen by comparing the relative positions of container 12 in FIGS. 3 and 4.

Continued extension of dumping rams l8 and 19 causes the container to pivot as seen in FIG. 5. Simultaneously, the door 24 is folded back as also seen in FIG. 5. After the compacted refuse has been dumped, as for example into a rear end loader 31 as seen in FIG. 9, the rams l8 and 19 retract, returning the container to the position shown in FIG. 3. The door 24 automatically closes and latches during this step, and the container is guided into position with the help of guides pins 381 cooperating with guide pins receiving means 40. The device 10 is then ready to compact additional refuse.

The hydraulic system for the illustrated preferred embodiment is made up of conventional controls, piping, and motors, and a detailed description is not necessary.

Many advantages are provided by the device as described above. The self-dumping ability avoids the requirements of a special dumping mechanism on the equipment the compacted refuse is dumped into, so that any rear end loader or other means can be used to receive the compacted refuse.

The specific connection between the frame 13 and the container 12 enables the container to move away from the packer 11 upon initial operation of the dumping rams. The seal between the packer and the container minimizes spillage and reduces the noise level of the device, and the unique design allows the container to be hydraulically pressed against the seal. The X configuration of the packing rams minimizes the space requirement for the device. The automatic latching and unlatching of the door 24, as well as the automatic folding thereof, reduce labor requirements and prevent spillage resulting from compacting refuse into an open container. The guide pins align the container with the packer after each dumping, again minimizing spillage.

The above detailed description of the preferred embodiment of the invention is intended to be illustrative, rather than limiting. It will be apparent that numerous modifications and variations could be made within the true scope of the invention, which is to be defined by the appended claims.
