| 1. A domestic plastic bottle shredding machine comprising:
(a) a housing;
(b) a lid;
wherein the lid is hingedly attached to the housing by a hinge;
wherein a ON/OFF switch is located along a predetermined position on the lid;
(c) a micro switch;
wherein the micro switch has components permanently mounted at predetermined locations to both the lid and the housing;
(c) a removable trash bin;
wherein a handle is incorporated along the upper front portion of the front side of the removable trash bin;
wherein the removable trash bin is located near the bottom of the housing and collects debris internally descending to the
bottom of the housing;
wherein a micro-switch is located along a side of the trash bin and adjacently to an interior portion of the housing for the
purpose of shutting off electricity when the micro-switch makes and sends a signal;
(d) a hydraulic ram assembly;
wherein the hydraulic ram assembly is located along the upper interior portion of the housing;
wherein a hydraulic ram mounting plate is permanently attached to an interior surface of the housing by a plurality of hydraulic
ram assembly mounting fasteners;
wherein a plurality of hydraulic rams are permanently mounted to the hydraulic ram mounting plate;
wherein a ram plate is connected to the opposite end of the hydraulic rams;
wherein a plurality of roller bearings are attached to the ram plate and provided rotational support to any refuse being inserted
into the machine for shredding;
wherein the plurality of roller bearings may move independent of each other;
wherein the hydraulic rams are driven by a hydraulic oil that is circulated in a hydraulic oil system comprising a hydraulic
oil reservoir that is connected to a hydraulic pump, and where the output of the hydraulic pump is connected via a high-pressure
line to all of the hydraulic rams;
wherein the hydraulic ram assembly is situated within the interior of the housing such that the directional movement of the
hydraulic rams is parallel with the ground;
(e) a guide roller assembly;
wherein a guide roller plate is permanently attached to an interior surface of the housing by a plurality of guide roller
assembly mounting fasteners;
wherein a plurality of guide rollers are mounted to the guide roller plate such that the guide rollers can rotate with respect
to the guide roller plate;
wherein the guide roller assembly is parallel to and corresponds with the hydraulic ram assembly;
wherein the guide rollers are propelled by chain sprockets;
wherein the chain sprockets are attached to the roller plate and guide rollers;
wherein the chain sprockets are propelled by a chain driven system consisting of a chain, a gear reducer, a chain sprocket
attached to the output of the gear reducer, and a motor attached to the input of the gear reducer;
(f) a shredding mechanism;
wherein the shredding mechanism is located within the interior of the housing and below both the hydraulic ram assembly and
the guide roller assembly;
wherein the shredding mechanism consists of a pair of rotating blades that complement each other;
wherein the shredding blades are rotated by a gear reducer, which is powered by a motor; and
(g) a separation wall;
wherein a separation wall is integrated into the interior design of the housing and is adjacent to the shredding mechanism;
and
wherein the separation wall prevents shredded plastic pieces from entering the mechanical components of the hydraulic ram
assembly.
