Abstract

The invention is a domestic plastic bottle shredding machine. The machine has a hydraulic ram assembly located above the shredding mechanism so that any plastic, glass, paper, or aluminum that is introduced will be flattened prior to being shredded. A waste bin is located beneath the shredding mechanism such that the storage process is driven by gravity. The machine is designed for domestic uses such that the shape of the machine resembles a small garbage can. The primary feature of this invention is to aid the recycling process by shredding plastic, glass, paper, or aluminum in advance of the recycling process.

Claims5

Dependent claims

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.
