Abstract

Device and method for transferring waste from a transfer plant to a container.

Device for waste transfer from a transfer plant (2), where they have been unloaded by the transport truck, to a container (1), comprising two homologous mechanisms, fixed on both sides of the plant transfer (2), which work in unison, pulling and approach of the filling container and its clamping in the area of work. The invention also includes a method for transfer of waste from a transfer plant to a large container.

Description

Device and method for transferring waste from a transfer plant to a container.

Object of the invention

The present invention relates to a device that allows the transfer of waste located in a transfer plant, after being unloaded by the truck of transport, to a container. This device is constituted by mechanical, drive elements electro-hydraulic traction and approach to the container, as well as its support in the area of job.

Background of the invention

At present, all solid waste urban (RSU) are collected by special trucks and dumped in the hopper of which the transfer plant is equipped, from where they are transferred to large standardized containers capacity.

A hydraulic system, driven by a unit of independent power, pushes solid waste towards the inside the container, using the hydraulic power to initially compact the waste until the payload is completed Available in the container.

Waste transfer operations are therefore, based on the operation of the positioning system and holding the container in its working position, for which they will use common elements, fully integrated in the part upper of the transfer block, not being precise the installation of elements in other areas of the equipment.

Among the documents that are part of the state  of the technique of this invention we highlight the following:

The document ES-8702851 which is refers to a mechanism for automatic garbage collection by dump trucks consisting of two pairs of cylinders hydraulics mounted on the rear rear, on both sides sides of the vehicle body, being the mission of the first pair of cylinders raise the articulated bottom of the truck's box in order to compress the garbage towards its part front in which it is accumulated, while the second pair of cylinders is intended for lifting and tilting of garbage containers; and from a door folding located at the rear of the truck, which opens by turning it down, which favors the operation of truck unloading

In EP-0763487 it is presents a waste collection vehicle comprising a essentially container-shaped cargo container that has a loading opening at the rear of the vehicle, a device loader attached to the cargo container at the rear and is provided with a collection tray and a compression mechanism to move the garbage deposited loosely in the bucket of collection inside the cargo container and simultaneously Compress the trash.

Document ES-2166643 describes a truck for garbage and waste collection that includes a rear loading hopper, with means to lift and unload containers, which has a rack installed that supports the container lifting mechanism, laterally movable by guides provided in said hopper to selectively position itself facing one or the other of the cargo box compartments. The displacement of the frame and lifting mechanism assembly is preferably carried out by means of a hydraulic cylinder of double effect, and the guides through which said set moves are located, one on the upper edge of the loading hopper and the other at the bottom edge of it.

Document ES-2130908 describes a system of reception, containment, and compaction of waste solids formed by a truck with a waste compactor box and a crane handling a receiving container and containment of waste destined to be compacted. Box compactor includes hydraulic drive means of the loading and unloading doors, as well as security means in the closing of the discharge door on which the compaction by pushers of waste by a vertical and movable wall inside the box compactor The crane includes container hooking means to be able to place it facing the loading door of the compactor and drive means of an opening mechanism of the container discharge gates.

Description of the invention

The device for waste transfer from a transfer plant to an existing container in the transformer plant, of the present invention is constituted by two homologous mechanisms, fixed on both sides of the transfer plant, which work in unison, each of the which includes:

to)

A approach, locking and fixing arm that makes a small approach movement to the existing container in the area of work of the transfer plant, powered by a hydraulic cylinder

b)

A rocker arm of the corresponding arm approach, which produces the lateral displacement of said arm, to get the release and grip of the container, actuated by means of a hydraulic cylinder.

C)

A hydraulic rocker that is located in a position that allows release of standard latches from the cover of the container, which is operated by a cylinder hydraulic.

The operating method of the device The invention is as follows: starting from a waiting position in which the approach and locking arms are fully extended and open, once the container is placed in position within the processing plant; in a single operation,  the arms close approaching their position, while the nails are approaching the support area to perform the unlocking of the latches of the standard container lid. One time Transfer work completed, and also in a single operation, latches actuated by hydraulic cylinders lock the container lid again in the position of transport and push the approach arms into position external, while the cylinders produce the opening of said arms to allow the removal of the container by the self-loading truck

For the best understanding of how much is left described herein are accompanied by some planes in which by way of example the device operation is represented here recommended.

Description of the figures

Figure 1 shows, in plan, the position of the container at the time of being deposited in the area next to the transfer plant (2).

In figure 2 the container (1) has been Approximate to the transfer plant (2).

All moving and interesting parts integrated into the movement have been highlighted with numbers for clarify the description of its operation.

Preferred Embodiment of the Invention

In figure 1, the position is shown in plan  initial or starting, the waste discharge zone, with the container located in after being unloaded by the truck transport.

A set of joining mechanisms is installed mechanics between the transfer plant (2) and the container (1) existing in the processing plant, composed of:

Two approach and locking arms (3) that carry out the approach of the container (1) to the plant area transfer (2), while getting their fixation through a hydraulic system

Two drive rockers (4) of the approach arms (3) cause lateral displacement of said approach arms, to produce release and grip of the container (1) according to the direction of operation.

Two hydraulic rocker arms (5) are located in position to allow the release of the standardized latches (11) of the container lid (1).

The support structure of the arms of approach is responsible for transmitting to the structure of the transfer plant (2) container fixing effort (1), and has a guided support by means of wheels for arms approach phones.

The sequence of operation is as follows: A from the position indicated in figure 1, with the container (1) located by the truck with self-unloading in its position split, the arms (3) are fully extended, operated by the hydraulic cylinders (6), and opened by the action of the lateral cylinders (7) of the rocker arms hydraulic (4). In this position, wait for the approximation of container (1).

Once the container is in position,  the arms (3) are closed by rocker action (4), bringing its position closer to the nail support area of the approach arms (3). Acting hydraulic cylinders (6) the approach of the container (1) to the position occurs suitable for the transfer of waste (2).

The hydraulic rocker arms (5) produce the unlocking the latches (11) of the container lid standardized, to allow the transfer of material. At this point of operation corresponds to the position indicated in figure 2.

Once the work of transfer, latches actuated by hydraulic cylinders (6) again lock the container lid in the position of transport and push the approach arms (3) into position external, while the cylinders (7) produce the opening of the arms (3) to allow the removal of the container by of the self-loading truck.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation.
