Abstract: A juice extractor includes a main body equipped with a motor, a gear box having a first shaft and a second shaft to which torque of the motor is transmitted, a housing having a flange connecting surface at the front of the main body, and a pair of squeezing rollers accommodated by the housing and connected to the second shaft so as to receive torque therefrom. First and second clutch gears are alternatively connected to the first and second shafts by a clutching fork extending into the gear box. A connecting gear is connected to the clutch gears. A threaded portion extending to the front of the gear box from the connecting gear is received in a threaded hole in the housing to enable the housing to be separated from the main body.

Abstract: A juice extractor for extracting juice from raw juice containing materials includes a raw material supply hopper of a housing engaged with a main body. The juice extractor includes a pair of squeezing rollers engaged with each other and mounted in the housing. Each of the rollers includes a helical gear and a screw at its leading end portion. A filter surrounds the leading end portions of the squeezing rollers and a discharge section plate is mounted at the leading end portion of the housing and has a discharge pressure adjusting device. Ring gears made of synthetic resins are mounted at both sides of the helical gear of one of the squeezing rollers whereby an interval between the helical gears of squeezing rollers is maintained. Grooves are formed at both sides of the threads of the helical gears of each of the squeezing rollers at a location beneath the raw juice material supply hopper.
