The rapeseed vibration screening device for vegetable oil production as claimed in claim 3, wherein a linear bearing (37) is fixedly embedded in one side of the box body (2), and one end of the sliding rod (13) penetrates through an inner ring of the linear bearing (37) and is connected with the inner ring of the linear bearing (37) in a sliding manner.
9. Use of a device for the vibratory screening of rapeseed as claimed in any one of claims 1 to 8, characterized in that it comprises the following steps:
s1, putting the raw material of rapeseeds into the box body (2) through the feed hopper (3), enabling the raw material of rapeseeds to fall on the first screening plate (5), starting the driving motor (10) to drive the turntable (11) to rotate, and the rotating rod (12) is respectively connected with the rotating disc (11) and the sliding rod (13) in a rotating way, therefore, along with the rotation of the rotary table (11), the slide rod (13) drives the connecting block (9) and the first screening plate (5) to move leftwards along the track of the arc-shaped groove (8), and the first spring (6) is compressed by the pushing force of the first screening plate (5), when the sliding rod (13) moves rightwards along with the rotation of the rotary disc (11) and is separated from the connecting block (9), the first screening plate (5) is moved rightwards along the track of the arc-shaped groove (8) by the elastic force of the first spring (6), further, the first screening plate (5) does reciprocating motion, so that solid impurities such as crushed leaves and crushed rods in the rapeseed raw material on the first screening plate (5) can be screened;
s2, when excessive solid impurities such as broken leaves and broken rods are accumulated on the first screening plate (5), starting a hydraulic cylinder (18), wherein a piston rod of the hydraulic cylinder (18) pushes a connecting rod (17) and a square frame (16) to move upwards, so that a sliding block (15) and a rotating plate (4) can move upwards along the track of an arc-shaped sliding groove (34) by taking a rotating shaft (14) as a fulcrum, and the impurities on the first screening plate (5) are discharged from a first discharging port (19);
s3, when the rapeseed sieved by the first sieving plate (5) falls onto the second sieving plate (20), the rotating motor (23) is started, the rotating motor (23) drives the rotating shaft (24) to rotate, the rotating shaft (24) drives the two cams (25) to rotate, when the protruding part of the cam (25) is in contact with the second sieving plate (20), the cam (25) pushes the second sieving plate (20) upwards, the second spring (22) starts to stretch, when the protruding part of the cam (25) is separated from the second sieving plate (20), the second sieving plate (20) moves downwards under the tension of the second spring (22), and the second sieving plate (20) vibrates upwards and downwards along with the rotation of the rotating shaft (24), so that small-particle impurities in the rapeseed on the second sieving plate (20) can be sieved;
s4, when excessive finished rapeseeds are accumulated on the second screening plate (20), the circular rod (31) is pulled to one side, the tension spring (32) is in a tension state at the moment, then the circular rod (30) is pulled upwards, the circular rod (30) drives the door plate (28) to move upwards along the sliding groove (27), the second discharge port (26) can be opened, then the tension on the circular rod (31) is released, the circular rod (31) retracts downwards under the action of the tension spring (32), the circular rod (30) can be prevented from falling back downwards, and the finished rapeseeds on the second screening plate (20) can be discharged from the second discharge port (26);
s5, the small particle impurities screened from the second screening plate (20) fall onto the concave disc (35), and the small particle impurities fall through the concave disc (35) and are discharged from the discharge pipe (36).
