Description

Technical Field

[0001] The invention relates to agricultural machinery, in particular to an axially rotating block-shifting seed cleaning device. Background Art

[0002] Traditional seed cleaners usually remove unqualified seeds and impurities by vibrating and translating the screen plate during operation. However, this cleaning method is too simple and the seed cleaning effect is not strong. When the screen is damaged, the entire device cannot work, which will cause the seed cleaning rate to decrease. The unqualified seeds after screening need to be collected manually, which increases the labor intensity. Summary of the invention

[0003] The purpose of the present invention is to develop an axially rotating block-shifting seed cleaning device, which enables eight sieves to independently rotate around the center to a certain extent, thereby solving the problem of too single seed cleaning method and the problem of manual collection of unqualified seeds after screening.

[0004] The object of the present invention is achieved by providing an axially rotating block-shifting seed cleaning device, characterized in that: the upper sieve moving part is composed of a frame (18), a support frame (13), a cleaning screen (3), a support rod (7), a slider (6) and a bracket (17) connected and matched in sequence, and the lower power input part is composed of a large bevel gear (9), a small bevel gear (11), a transmission shaft (10), a rotating wheel (8) and a rotating shaft (12); in the upper sieve moving part, the frame (18) and the support frame (13) are fixedly connected, the front end of the cleaning screen (3) is connected to the bracket (17) by a pin, and the rear end is connected to the support rod (7) by a pin. The slider (6) and the guide rail are clearance-matched, and the support rod (7) and the slider (6) are clearance-matched; in the lower power input part, the rotating shaft (12) and the support frame (13) are matched through bearings, the rotating wheel (8) and the rotating shaft (12) are key-connected, the transmission shaft (12) and the small bevel gear (11) are key-connected, and the motor (5) is interference-fitted; the motor (5) transmits the rotation to the small bevel gear (11) through the transmission shaft (12), thereby driving the large bevel gear (9) to rotate, and then the rotating wheel (8) rotates around the center. During the rotation process, the convex end of the rotating wheel (8) will lift the support rod (7) in turn, so that the cleaning screen (3) rotates a certain range with the bracket (17) as the center, so that the screen performs a cleaning operation.

[0005] The beneficial effects created by the present invention are as follows: the motor (5) drives the small bevel gear (11) to rotate, the small bevel gear (11) and the large bevel gear (9) are meshed, so that the large bevel gear (9) drives the rotating shaft (12), and the rotating shaft (12) drives the rotating wheel (8) to rotate. In the process of the rotating wheel (8) rotating around the center, the convex end will lift the support rod (7) in turn, and the support rod (7) will move upward to make the cleaning screen (3) rotate around the bracket (17), and then the support rod (7) will drive the slider (6) to slide along the guide rail toward the center, and the gravity of the material will make the seeds slide on the screen surface, increasing the seed screening area, and unqualified seeds and granular impurities at the front and rear ends of the screen will enter the front slideway (14) and the rear slideway (16) through the screen holes, and finally reach the seed collecting bucket (2) and complete the cleaning. The eight screens can move independently without affecting each other, and the structure is simple and reliable, and the operation is convenient, which can solve the problem of a single screen movement mode.
