Abstract

A device 1 for compacting garbage into and unloading thereof from a transportable bin 17 provided with an upper opening 33 for loading from the top, comprises a pusher shield or cap 3 for pushing the garbage towards an unloading opening at the rear of the bin, a loading hopper 5, and a pusher plate 12 driven by means 14 to push garbage from the hopper 5 through an opening 7 under the shield 3 and into the bin. The device is displaceable by means 27 from a first position, where the loading opening 6 of said hopper is aligned with said upper opening 33 of the bin, to a second unloading position adjacent said unloading opening of the bin to eject the garbage from the bin. <IMAGE>

Description

SPECIFICATION An automatic device for compacted stowage of garbage into and unloading thereof from a transportable bin This patent for industrial invention is concerned with an automatic device for compacted stowage of garbage into and unloading thereof from a transportable bin.

In the field of refuse collection services there is an increasing trend to provide means operable by a single operator and provision has been already resorted to for making transportable bins having an upper opening for loading from the top and a pusher shield or cap for the garbage towards an unloading opening on the rear of the bin.

Generally, loading from the top occurs by providing the means with a suitable crane, operating on the front of the vehicle and hooking a conventional refuse collection container, turning it upside down at said upper opening.

The pusher shield or cap is activated to compact the refuse or garbage within the bin and causing the unloading thereof after transporting the bin to the predetermined zone.

The above outlined conventional solution has the disadvantage of not allowing a correct compaction of the refuse or garbage, and particularly of enabling the container overturning only when the shield or cap is stationary: as clearly apparent, this is time consuming with evident drawbacks resulting therefrom.

It is the object of the present invention to provide an automatic device for compacted stowage and unloading of garbage, substantially eliminating the above mentioned disadvantage.

This and other objects of the invention will become apparent to those skilled in the art from reading the following description and claims.

According to the invention, an automatic device for compacted stowage of garbage into and unloading thereof from a transportable bin, provided with upper opening for loading from the top and a pusher shield or cap for said refuse or garbage towards an unloading opening on the rear of said bin, is essentially characterized by providing, in combination with said shield or cap, a loading hopper forming part of said device, an unloading opening of said hopper within said bin, and a pusher plate arranged as a continuation of the hopper and in alignment with the unloading opening of the latter.

More particularly, the device comprises a frame and drive means associated with said frame for displacing the latter from a first position, where the loading opening of said hopper is aligned with said upper opening of the bin, to a second unloading position opposite to said first position and adjacent to said unloading opening of the bin, and vice versa.

The pusher plate is associated with said frame and provided with drive means for displacing it from a first position, where such a plate is a continuation of said hopper, to a second position, where it is outside of the unloading outlet of the hopper, and vice versa.

A preferred embodiment of the device according to the invention is shown by way of unrestrictive example in the figures of the accompanying drawings, in which: Fig. 1 is a cutaway view of a transportable bin provided with the device according to the invention; Fig. 2 is a fragmentary enlarged view in the direction of arrow A of Fig. 1; Fig. 3 is a sectional view taken along line Ill-Ill of Fig. 1; Fig. 4 schematically shows the device when loading and compacting the refuse or garbage within a motor transported bin; and Fig. 5 is similar to Fig. 4, but showing the device when unloading the refuse or garbage.

Referring to the above figures of the accompanying drawings, the device generally designated at 1 is formed of an iron frame 2 substantially comprising a shield or cap 3, an inclined wall 4 defining with a wall 3', at the rear of said shield or cap 3, a loading hopper 5 which is open at the top at 6 and opens in an unloading opening 7 defined by an upper edge 8, a lower edge 9 and two side edges 10.

At horizontal position relative to the unloading opening 7, the frame 2 has a space or chamber 11 for the housing and sliding of a pusher plate 12 provided with upper plate 1 3 and controlled for displacement in the direction of arrows F and F' by a hydraulic cylinder 4, pivoted at 1 5 on the bottom wall of space or chamber 11 and at 1 6 on the back of plate 1 2. At the retracted position (arrow F') of plate 12, shown in Figs. 1, 3 and 4, the hopper 5 is in communication with the opening 7 and the plate 12 is the continuation of the inclined wall 4, while at the advanced or forward position (shown by dashed lines in Fig. 4, arrow F) the plate 12 is substantially arranged as a continuation of the shield or cap 3 and the upper plate 13 thereof is the closure for the hopper 5 flush with the upper edge 8 of the unloading opening 7.

The device 1 has such dimensions as to be exactly contained within a transportable bin, generally designated at 17, of rectangular or square cross-section and defined by a bottom wall 18, two side walls 19 and a top closure wall 20, and rearwardly provided with a semispherical door 21. Said door is hinged at 22 on the top wall 20 of the bin 1 7 and the opening and closing thereof is controlled by a hydraulic cylinder 23, as shown in Figs. 4 and 5.

Laterally of the device 1 and at suitable positions, a plurality of rollers 24 are provided, engaging guides 25 integral with the side walls 1 9 of the bin and, at a median location 26 of the joining zone between the inclined wall 4 and the wall 11' defining at the top the space or chamber 11 , the end of a hydraulic telescopic element 27 is pivoted, the other end of which is pivoted at 28 on the bin.

As particularly shown in Fig. 2, guides 29 are provided alongside the vertical inner walls of the unloading opening 7, engaging rollers 30 carried by the pusher plate 12, and this to provide the latter, through the action of the hydraulic cylinder 14, with the desired alternating movement in the direction of arrows F and F'. The pressure oil supply to the cylinder 14 occurs through flexible conduits 31 (Fig. 5) which can wind up on and unwind from an unwinding element 32 mounted internaily of the bin 17.

At the unloading position of the bin 1 7, the device 1 is at the position shown in Figs. 1 to 4, with the opening 6 of the hopper 5 at an opening 33 on the top wall 20 of the bin at a location of the latter opposite to the hinging location 22 for the door 21. This enables a conventional refuse collection container 34 (Fig. 4) to be drawn from ground floor by a suitable crane (not shown) and overturned so as to unload its contents within the openings 33 and 6. The cylinder 14 is constantly operated to alternatively displace the plate 12 in the direction of arrows F and F'.

By such an operation, the refuse moves downward along the hopper 5 and is continuously pushed by the plate 12 Into the bin 1 7 until the latter is completely compacted filled. it should be pointed out that the semispherical configuration of the door 21, now closed, facilitates such a filling operation, causing the refuse to follow the path indicated by arrow H. The refuse loading operation can be continued owing to the provision of the plate 13 preventing the refuse from invading the rear zone of the plate 12, when the latter is at extracted position (arrow F).

Following the compacted filling of the bin 17 and transportation thereof to the unloading zone, the door 21 is opened and the whole device 1 (Fig.

5) advanced through the operation of the telescopic element 27, maintaining the plate 1 2 in continuous alternating movement for causing the compacted mass to be crumbled and facilitating the unloading operation due to the thrust of the shield or cap 3 against said mass. The supply to the cylinder 14 is assured also during the unloading step by the flexible conduits 31 following the device 1.

The stepped space or chamber 35 (Figs. 4 and 5) at the opening 33 has only the function of maintaining as low as possible the path G for the container 34 to not interfere with any aerial electric wires or other obstructions provided in the town streets.
