Description

"PLATE COMPACTOR IMPROVEMENT FOR MOTORIZED WASTE COLLECTORS"
This invention concerns the improvement developed on the hydraulic plate compactor operating inside the framework of motorized waste collectors in general such as: home, industrial and farming waste collectors.
Compaction is one type of preliminary waste treatment conducted to reduce the volume of disposed waste. This preliminary treatment helps to store, transport and conduct the final treatment, i.e., the recycling, incinerating, earthwork, or simple disposal in nature. As a rule, compaction entails the use of presses or may be done inside the transporting vehicle like, for example, inside the refuse trucks.
The purpose of the vehicle shown in patent BR Pl 0300535-6 dated 03/11/2003 was to collect, compact, bag up waste in general; moreover, it had a chassis to support the framework closed with a back closing door, inside of which a hydraulic system displaced a mobile waste plate compactor. The back door moved at an angle of the chassis, thereby transforming into a chute to unload the compacted waste. A feeding device with a flexible waterproof tube was placed at the far back end of the framework so as to receive the compacted matter when unloading.
The plate press is activated through four telescopic arms propelled by three separate hydraulic cylinders. The plate press is composed by a lower semi-dish, on which a specific hydraulic cylinder articulates an upper semi-dish. The upper semi-dish is always maintained lowered so that the platform formed is aligned with the loading part of the framework.
The plate tilts forward for a homogenous compaction of the waste located at the bottom and at the top of the framework. As the plate tilts along its course inside the framework, a pair of sliding tongues makes the plate circular when they slide inwards and elliptical when they slide outwards. Propelled by the hydraulic cylinders, the telescopic arms make the plate move forward towards the back door. At the beginning of the compaction stage, this plate is tilted to help raise the waste and avoid a higher level of compaction at the base of the framework. By the end of the course, a hydraulic cylinder corrects the position of the plate by placing it at a right angle from the framework shaft and parallel to the back door.
The plate compactor is activated through the following sequence of steps:
The waste enters the framework through the front opening made when tilting the upper semi-dish of the press plate;
To compact the load, the upper semi-dish is raised and the hydraulic cylinders are activated so that the said arms push the plate compactor towards the closing door of the framework;
After various successive waste pressing and loading cycles, the load is disposed and so the back door is opened to form a chute for the compacted matter to slide down.
Dismounting a plate with such a construction and quantity of components is complex. It requires tilting the plate and articulating the upper and lower semi-dishes through specific hydraulic systems, which make the assembly and maintenance of the vehicle all the more complex. Besides, in order not to have any load surge during the compaction process, a system of retractable arms is required to seal the plate when it is tilted, which proved to be difficult to operate and not very efficient.
This invention aims therefore to improve the plate compactor inside the framework of motorized waste collectors for a proper resolution of any of the abovementioned problems of the state of technique. This is achieved thanks to a plate compactor formed by two semi-dishes, an upper and a lower one, activated by a separate hydraulic system. The horizontal circular plate of the lower semi-dish forms a platform that loads the waste when the upper semi-dish is drawn back. The upper semi-dish moves forward regularly to draw the waste on the platform. When the compaction of the waste is required, both semi-dishes move forward simultaneously and form a compaction wall.
As a result, the plate compactor improvement for the framework of vehicles in reference in this invention has the following advantages compared with the compaction systems known to this date: It is formed by two semi-dishes that move independently; It turns into a platform when the upper semi-dish moves backwards to expose the horizontal circular plate connected to the lower semi-dish for an easier waste load; - It operates at a right angle from the shaft of the framework and so no sealing mechanism such as tongues or any other similar mechanism is necessary;
It ensures a homogenous waste compaction without requiring tilting the compaction plate; - There is no need for the hydraulic system required to tilt one semi-dish over another; Its assembly and operation are simplified.
The plate compactor improvement for motorized waste collectors in reference in this invention is better understood in the following detailed description based on the appended drawings listed below, illustrating the preferred form; nevertheless, this form should not be considered as the only possible one for this invention, these drawings are:
Figure 1 - perspective of the compactor device once out of the vehicle;
Figure 2 - side view of the compactor device; Figure 3 - back view of the compactor device; Figure 4 - side view of the compactor device assembled on the framework of a motorized waste collector; Figure 5 - side view of the compactor device operating inside the framework of the motorized waste collector. Figures 1 to 3 illustrate the compactor device made up by a lower semi-dish (1 ) and an upper semi-dish (2) equipped with separate hydraulic systems. One horizontal circular plate (11) is connected to the lower semi-dish (1 ) to form a platform that loads the waste when the upper semi-dish (2) is drawn back. The lower semi-dish (1 ) is activated by hydraulic cylinders in series (12) and guided by a central telescopic arm (13). A bearing (14) connects the central telescopic arm (13) to the framework of the vehicle.
An upper telescopic arm (21 ) is fixed to the central arm (13) through plates (15). This upper telescopic arm (21) is activated through a hydraulic cylinder (22).
Figures 4 and 5 illustrate the framework of the motorized waste collector (3), which has a chassis (31), a tilting back door (32) and a loading platform (33). The bearing (14) of the central telescopic arm (13) pivots on an internal base (34) inside the front wall (35) of the framework.
When the hydraulic cylinders in series (12) are activated, the central telescopic arm (13) extends and pushes the lower semi-dish (1) forward until it reaches the tilting back door (32). The plates (15) that are connected to the two telescopic arms (13 and 21) then draw the upper semi-dish (2). Then, the hydraulic cylinder (22) is activated thereby extending the upper telescopic arm (21) while making the upper semi-dish (2) move forward towards the tilting back door (32), thereby completing the waste compaction cycle.
The loading efficiency and high compaction rate of the waste to process are obtained through the following two steps: by moving the lower semi-dish (1 ) forward, using all the power of its propelling cylinders (12), and then by collecting the other compaction stage with the upper semi-dish (2) through its own propelling cylinder (22). Therefore, the final compaction occurs twice thereby increasing the efficiency of the system, since the cylinder (22) activating the semi-dish (2) has the same capacity as the cylinders (12) that propel the lower semi-dish (1). Since the cylinders operate separately on each semi-dish (1 and 2), the compaction rate is double that obtained in the conventional system, and is distributed uniformly. The separate sliding semi-dish system (1 and 2) enable a wider loading opening at the front of vehicle framework, and thereby any possible automatic loading.
