Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes: working plane 1, 2, 3, crank mechanism 4, leaf spring 5, 6, 7, 8, connecting rod 9, 10, hinge 11, 12, 13, 14, drive motor 15, frequency conversion device 16.

[0012] The working plane 1 is elastically installed on the working plane 2 through four spring pieces 5, 6, 7, 8; the crank mechanism 4 is connected with the runner of the driving motor 15; the driving motor 15 is rigidly installed on the working plane 2, and the driving motor When 15 rotates, the working plane 1 will reciprocate left and right under the action of the crank mechanism 4; The angle can adjust the front and rear inclination of the working plane 2; the working plane 3 is fixed on the base of the polishing machine through the hinges 13, 14 and the connecting rod 10, and the working plane can be adjusted by adjusting the angle of the two arms of the connecting rod 10 3 to the left and right inclination. The output end of the frequency conver...

Abstract

A full-state in-line adjustable gravitational seed-screening machine with in-line regulation of vibration frequency and inclination is composed of three working planes, crank mechanism, 4 leaf springs, 2 connecting rods, 4 corner hinges, drive motor and frequency converter. The first working plane is elastically installed on the second one via 4 leaf springs. The second working plane is fixed to the third one via two corner hinges and the first connecting rod. The third working plane is fixed to the base of polishing machine via another two corner hinges and the second connecting rod.

Description

technical field [0001] The invention relates to equipment in the technical field of agricultural machinery, in particular to a machine for gravity screening of seeds. Background technique [0002] Seed gravity sorting sorts seeds according to their weight, size and density, which is an irreplaceable and important link in the process of seed processing. The basic principle is: through a small amount of impact on the seeds, the seeds can obtain the initial speed of flying in the air. The initial speed is related to the weight of the seeds; The direction and distance that seeds fly in the air, so seeds with different specifications, weights, sizes and densities can be obtained in different directions and distances. Today's seed gravity screening machines use the following mechanical principles to achieve the above sorting process. That is to say, the crankshaft eccentric mechanism and the flexible reed drive the reciprocating vibration of the sieve bed first, so that the seed...
