A trash compactor may include a frame, a cavity, a trash receptacle, a platen movable to compress trash collected in the trash receptacle, a set of linkages and a drive mechanism configured to drive said platen up and down, the drive mechanism further configured as one of the link elements, and a platen guide mechanism configured to restrict the motion of the platen in an up and down manner.

An apparatus and method for baling plant materials such as grasses, leaves and pine straw a hydraulic power unit, a conveyor operatively coupled to the hydraulic power unit, a hopper for depositing the material on a proximal end of the conveyor and a baler operatively coupled to the hydraulic power unit and arranged for receiving a material from the conveyor. The power unit, conveyor and baler are supported on a trailer. An electronic control system is operatively coupled to the hydraulic power unit, the conveyor and the baler for automatically suspending operation of the conveyor when the baler contains a sufficient amount of material for initiating bundling of the material and automatically resuming operation of the conveyor following dispensing of a bundle of the material from the baler.

An agricultural harvesting machine for crop material including a crank arm connected to a rotational power source, a plunger having an extended position which is located further rearward in a compression chamber than a retracted position, and a connecting link connected between the plunger and the crank arm. One of the connecting link and the crank arm has a variable length. The plunger moves between the retracted and extended positions during a run mode as the crank arm rotates. The plunger changes speeds during an event phase based upon one of the connecting link and the crank arm varying lengths.

An apparatus including an accumulator and a drive mechanism. The accumulator includes an energy storage apparatus with a first piston face configured to reversibly compress an energy storage medium and a second piston face forming at least part of an inner surface of a corresponding second fluid chamber reversibly expandable by movement of the second piston face. A third piston face forms at least part of an inner surface of a corresponding third fluid chamber reversibly expandable by the third piston face. The first, second and third piston faces are coupled together.

A method and system for compacting waste materials in a collection container. The container can be a freestanding waste container, a self-contained compaction container, or a container on a waste collection vehicle. A hydraulically operated compactor blade is positioned in the upper portion of the container with its bottom edge a distance above the floor. A door member can be provided in the rear wall of the collection container. The compactor blade can be in its rest position relative to the top opening. The container member can be positioned or located on a trailer or truck-type vehicle and adapted to be tilted for evacuation of materials collected therein.

An apparatus for processing material in connection with a pneumatic material conveying system includes a waste container/separating device, into which material is configured to be conducted from a conveying pipe of the pneumatic material conveying system via an inlet aperture and which is configured to be connected to means for achieving a partial vacuum. The apparatus further includes a press device/compactor device, which is arranged to act on the material (w) conducted into the waste container/separating device, via at least one aperture formed in the container, and that at least one wall that is transverse with respect to the input direction of the material is arranged in the container space of the waste container/separating device, which wall is configured to guide the material into the operating range in the container space of the compressor of the press device/compactor device.

A bale ejection device for a baler for forming a bale includes a square bale chamber, a plunger having a packing face turned toward the bale accommodated within the chamber for movement, and at least one ejection ram selectively disposed at a position in which it projects beyond the packing face.

A baling press has a horizontal construction, for compaction of loose material, a pressing channel having a fill-in opening, a pressing plate that can be displaced in the pressing channel, a pressing surface that stands in contact with the material to be compacted, multiple hydraulic cylinders coupled with electro-hydraulic drive assemblies for generating a pressing force, for advancing the pressing plate for the purpose of introducing the pressing force into the filled-in material, as well as for returning the pressing plate to a starting position, and a control and regulation system configured for monitoring the spatial orientation of the pressing surface and keeping it constant during the advancing movement of the pressing plate.
