Noodles can be fully automatically, efficiently and quickly produced, the noodles can be directly cooked in water while being produced, and the machine is safe, quick, reliable and convenient.
A: Disclosed is a multi-functional noodle machine, comprising a machine body (1) and an electric motor (2) provided in the machine body, wherein a kneading bucket (3) is provided above the machine body, a stirring plate and a stirring rotating shaft are provided in the kneading bucket, a dough pressing barrel (4) is provided at the front of the machine body, a dough pressing screw (5) is provided in the dough pressing barrel, the front end of the dough pressing screw is sheathed with a replaceable noodle forming module (8), and a movable valve (31) is provided between the dough pressing barrel and the kneading bucket. Opening the movable valve throws dough in the kneading bucket into the dough pressing barrel under the centrifugal force of the stirring apparatus. A gear transmission system is provided between the electric motor and the dough pressing screw and stirring rotating shaft. The structure of the multi-functional noodle machine is simple.
B: A juice extractor, comprising: a juice extraction cup component (30), a spiral propeller component (20); a first grinding convex rib (32) is disposed on the inner wall (31) of the juice extraction cup component (30); an annular residue-blocking groove (33) is disposed at the bottom of the juice extraction cup component (30); an annular residue discharge platform (35) is formed between the residue-blocking groove (33) and the inner wall (31) of the juice extraction cup component (30); the spiral propeller component (20) is rotatably disposed in the juice extraction cup component (30); a spiral second grinding convex rib (22) is disposed on the peripheral surface (21) of the spiral propeller component (20); an annular residue-blocking rib (23) is disposed at the bottom of the spiral propeller component (20); the annular residue-blocking rib (23) is inserted into the residue-blocking groove (33); and a plurality of third grinding convex ribs (36) are intervally disposed on the top face of the residue discharge platform (35). In the juice extractor with the above structure, the first grinding convex rib (32) and the second grinding convex rib (22) are coordinated to grind fruit or vegetables the first time, and the third grinding convex ribs (36) and the bottom of the spiral propeller component (20) are coordinated to grind the fruit and vegetables the second time, thus greatly improving juice yield, and reducing the waste from raw juice material.
C: Disclosed is a drive device with a forward revolving blade and a counter-revolving blade, comprising a drive shaft (8), a forward revolving blade (2), a base unit (1) with a central hole, and a counter-revolving blade (3) with a central hole, wherein the drive shaft (8) passes through the central hole in the base unit and the central hole in the counter-revolving blade to connect with the forward revolving blade. The lower end of the drive shaft has a driving gear wheel (7), an inner gear wheel (4) and a bearing fixing seat (5) are provided in the base unit, and a driven gear wheel (6) is provided on the bearing fixing seat. One edge of the driven gear wheel engages with the driving gear wheel, and the other edge engages with the inner gear wheel. The counter-revolving blade is fixedly mounted on the top end of the inner gear wheel. Since the chopping action of the forward revolving blade and the counter-revolving blade works in different directions, the result is more finely processed food.
D: A mechanical underwater manual propeller, comprising a screw propeller (5) mounted on a screw propeller shaft (11); the screw propeller is provided with a first bevel gear (9) in the back, and is provided with a concentric protective ring (1) on the outer side; one side of the protective ring is provided with a support plate (6); the support plate is provided with a first gear (3) and a second gear (7) intermeshed thereon; the support plate is also provided with a transitional gear (2) thereon forming a meshing pair together with the second gear; the drive shaft of the transitional gear penetrates through the support plate, and one end thereof located in the protective ring is provided with a second bevel gear (10); the first gear is connected to a first connecting rod (4); the second gear is connected to a second connecting rod (8); and the screw propeller shaft is provided with a one-way flywheel thereon. The propeller utilizes the mechanical drive principle to convert human power into forward motion most efficiently, and can realize a high swimming speed without excessive consumption of energy.
