An automatic can crusher apparatus for crushing cans for recycling includes a housing having a ram aperture extending through to a housing inside. A ram has a pneumatic cylinder body, a ram arm extending through the ram aperture, and a ram head coupled to the ram arm. The ram moves the ram head between a load position and a crush position adjacent a housing right side. A can positioner is coupled to a housing left side within the housing inside to secure a can adjacent the ram head in the load position. A feeder chute is coupled to the housing top side to receive a plurality of cans through a chute top end and dispense each can through a chute bottom end onto the can positioner when the ram head is in the load position.

The invention discloses a light and convenient pneumatic tea brick preparing device, including a work table, a supporting device provided at a bottom of the work table, a punching device provided at a top of the supporting device and a limiting device provided at a top of the work table. An upwardly open rectangular accommodating cavity is provided at the bottom of the work table. The supporting device includes a supporting component, the punching device includes a power component, a punching component and a waterproof component, and the punching component includes a punching block. In this device, a working bin for holding tea leaves is formed by the limiting block, the rectangular accommodating cavity and the punching block, and the tea leaves in the working bin are punched by the punching block to form a tea brick which can be ejected together with the limiting block.

An apparatus for crushing aluminum beverage cans, including; a containment structure with an integral crushing chamber, a pneumatic crushing cylinder with a hub type crushing head which ensures the can remains inside the crushing chamber during the crushing event, an ejection cylinder with an ejection ram, solenoid control valves, a safety interlock switch and a 3 position control switch, an air/gas supply and distribution system and an electrical control system. Two pneumatic cylinders; which are supplied air via two 3-way solenoid control valves, are used to perform the crushing and ejection work. Simultaneous two handed switch operation is required to energize either of the 3-way solenoid control valves to route air to the pneumatic cylinders. Two handed switch operation ensures that the operator's hands are free of the crushing chamber during operation.

A pneumatic chamber 20 is configured to include a first pneumatic chamber 21 pressurizing a first piston 11 and a second pneumatic chamber 22 pressurizing a second piston 12. The first pneumatic chamber 21 communicates with the second pneumatic chamber 22. The hydraulic pressure generating unit 55 is internally provided with a hydraulic chamber 30, and the hydraulic chamber 30 is configured to have a first hydraulic chamber 31 pressurized by the first pneumatic chamber 21 via the first piston 11 and a second hydraulic chamber 32 pressurized by the second pneumatic chamber 22 via the second piston 12. The hydraulic pressure generating unit 55 is movable in a thrust direction in a cylinder 2, and the second hydraulic chamber 32 has a function of fixing the moving hydraulic pressure generating unit 55 in the cylinder 2 by causing a thin portion 15 to be elastically deformed in a radial direction due to hydraulic pressure. The first hydraulic chamber 31 outputs hydraulic pressure of the first hydraulic chamber 31, which is increased by the fixing, to an output rod 7.
