A citrus fruit squeezing machine has a section for accumulating and feeding the fruit, a section for squeezing the fruit and respective sections for conveying and collecting the juice and the peels of the squeezed fruit. The section for squeezing the fruit includes two plates disposed laterally as well as symmetrically to a cutting blade. The plates are supported in such a way as to be convergent and inclined downwards and towards the cutting blade. The cutting blade is fitted on a support plate having its lower part pivoted on the framework of the machine. The support plate is also connected with a toggle compound lever which can be manually driven or driven by a motor. The toggle compound lever moves the support plate towards the plates which are both straddled by the cutting blade when they are in the starting position. At first, the cutting blade moves toward the piece of fruit and cuts a fairly good part of it. Then, arms of the support plate impact corresponding rolls on the plates and drive the plates toward each other with the consequent squeezing of the fruit.

1. A machine for squeezing fruit, said machine comprising: a framework; a squeezing section in which the fruit is squeezed; a feeding section which feeds fruit to said squeezing section; and discrete conveying/collecting sections which convey and collect juice from the fruit and residual of the fruit, respectively; said squeezing section including two plates having rear edges adjacent one another and being supported so as to be swingable between a starting position at which said plates converge toward said rear edges thereof and collectively form a downwardly inclined chute and a squeezing position at which said plates are in a mutually facing relation, return springs urging said plates to said starting position, a cutting blade having a cutting edge facing said plates, the plates disposed laterally of and symmetrically with respect to said cutting blade, a support plate to which said cutting blade is mounted, said support plate being supported in the machine so as to be movable between a starting position at which the cutting edge of said cutting blade is remote from the rear edges of said plates and a cutting position at which said cutting edge is located adjacent the rear edges of said plates, and driving means for progressively swinging said two plates from the starting position thereof to said squeezing position and for moving said support plate a substantial amount from said starting position thereof towards said cutting position prior to the swinging of said two plates from said starting position thereof to said squeezing position such that said cutting blade will cut substantially into a piece a fruit received on the downwardly inclined chute before the piece of fruit is squeezed by said squeezing plates. 2. A machine for squeezing fruit as claimed in claim 1, wherein said driving means includes rolls disposed on said plates, arms extending from said support plate and having camming edges which engage said rolls as said support plate is brought to said cutting position in order to cam said plates to said squeezing position thereof against forces exerted by said return springs, and a compound lever connected to said support plate, said compound lever including a plurality of links pivotably connected to one another. 3. A machine for squeezing fruit as claimed in claim 2, wherein said support plate is pivotably supported in the machine so as to be pivotable between said starting position thereof and said cutting position. 4. A machine for squeezing fruit as claimed in claim 1, wherein said cutting blade is detachably mounted to said support plate. 5. A machine for squeezing fruit as claimed in claim 3, wherein said cutting blade is detachably mounted to said support plate. 6. A machine for squeezing fruit as claimed in claim 2, wherein said driving means further includes a manually operable lever connected to said compound lever. 7. A machine for squeezing fruit as claimed in claim 2, wherein said driving means further includes a crank connected to said compound lever, and an electric motor and speed reducer connected to said crank so as to rotate said crank. 8. A machine for squeezing fruit as claimed in claim 1, and further comprising pins disposed at a fixed location in the machine laterally of and symmetrical to a plane coincident with said cutting blade, said pins extending parallel to one another and being inclined downwardly toward said support plate, said plates being rotatably supported by said pins so as to be swingable about said fixed locations between the starting position of the plates and said squeezing position thereof, and said pins being spaced apart from one another by such a distance that said plates are parallel and spaced from one another when in said squeezing position. 9. A machine for squeezing fruit as claimed in claim 2, and further comprising pins disposed at a fixed location in the machine laterally of and symmetrical to a plane coincident with said cutting blade, said pins extending parallel to one another and being inclined downwardly toward said support plate, said plates being rotatably supported by said pins so as to be swingable about said fixed locations between the starting position of the plates and said squeezing position thereof, and said pins being spaced apart from one another by such a distance that said plates are parallel and spaced from one another when in said squeezing position. 10. A machine for squeezing fruit as claimed in claim 1, and further comprising arms connected to said plates, respectively, so as to swing therewith, and stopper elements which engage said arms so as to limit movement of said plates and establish said squeezing position thereof, said return springs being connected to said arms so as to bias said two plates to said starting position thereof via said arms. 11. A machine for squeezing fruit as claimed in claim 2, and further comprising arms connected to said plates, respectively, so as to swing therewith, and stopper elements which engage said arms so as to limit movement of said plates and establish said squeezing position thereof, said return springs being connected to said arms so as to bias said two plates to said starting position thereof via said arms. 12. A machine for squeezing fruit as claimed in claim 8, and further comprising arms extending from said fixed locations where said pins are disposed and connected to said plates so as to swing therewith, and stopper elements which engage said arms so as to limit movement of said plates and establish said squeezing position thereof, said return springs being connected to said arms so as to bias said two plates to said starting position thereof via said arms. 13. A machine for squeezing fruit as claimed in claim 9, and further comprising arms extending from said fixed locations where said pins are disposed and connected to said plates so as to swing therewith, and stopper elements which engage said arms so as to limit movement of said plates and establish said squeezing position thereof, said return springs being connected to said arms so as to bias said two plates to said starting position thereof via said arms. 14. A machine for squeezing fruit as claimed in claim 2, wherein said arms are disposed laterally of and symmetrically to said cutting blade and extend from sides of said support plate at approximately a longitudinally central location of said support plate, said edges of the arms being defined at inner portions of the arms facing each other, and said edges having respective central portions which are substantially rectilinear and extend orthogonally to one another, parallel portions each of which extends from one end of a respective said central portion to said support plate, and short portions each of which extends from the other end of a respective said central portion at free ends of said arms, the short portions extending in directions slightly divergent from one another away from said central portions. 15. A machine for squeezing fruit as claimed in claim 1, wherein said compound lever is a toggle joint, and said links include two rods having respective first ends pivotably connected to one another and respective second ends pivotably connected to said support plate and to said framework, respectively, and a connecting rod having one end pivotably connected to the first ends of said two rods. 16. A machine for squeezing fruit as claimed in claim 6, wherein said compound lever is a toggle joint, and said links include two rods having respective first ends pivotably connected to one another and respective second ends pivotably connected to said support plate and to said framework, respectively, and a connecting rod having one end pivotably connected to the first ends of said two rods and another end connected to said manually operatable lever. 17.
