Title:
MECHANISM FOR PREVENTING SEED GRADER FROM SHAKING EXCESSIVELY
Document Type and Number:
WIPO Patent Application WO/2020/258619
Kind Code:
A1
Abstract:
A mechanism for preventing a seed grader from shaking excessively comprises a grader frame (1) and a grader body (2). A first steel angle (3) and a second steel angle (4) are provided on a side of the grader frame (1) close to the grader body (2). A third steel angle (5) and a fourth steel angle (6) are provided on a side of the grader body (2) close to the grader frame (1). The first steel angle (3), the third steel angle (5), the second steel angle (4), and the fourth steel angle (6) are provided in that order from bottom to top. A first rubber spring (7) is provided between the first steel angle (3) and the third steel angle (5). An elastic movable end of the first rubber spring (7) is parallel to the grader frame (1). A second rubber spring (8) is provided between the second steel angle (4) and the fourth steel angle (6). An elastic movable end of the second rubber spring (8) is perpendicular to the grader frame (1). The two rubber springs perpendicular to each other are fixedly mounted between the grader frame (1) and the grader body (2) by means of the four steel angles, such that cushioning is achieved between the frame (1) and the body (2), thereby preventing the body of the seed grader from being dislocated and damaged due to excessive shaking, and extending the service life of the device.
