When needs carry out the sesame screening, the user can start driving motor 121 and rotate, and driving motor 121 rotates and drives pivot 123 and rotate, and pivot 123 rotates and drives gear 124 and rotate, and gear 124 rotates and drives outer ring gear 126 and rotate, and outer ring gear 126 rotates and drives screening frame 9 and rotate, and screening frame 9 rotates and screens the sesame, and after the sesame was screened and is closed, close driving motor 121 can.
Initially, the second spring 138 is in a compressed state, firstly, a user pours sesame into the charging box 134, when the charging box 134 is filled with a proper amount of sesame, the pouring of sesame is stopped, further when the driving motor 121 is started, the rotating shaft 123 rotates and also drives the disc 131 to rotate, the disc 131 rotates and drives the ball 132 to rotate, when the ball 132 is not in contact with the cross bar 137, under the action of the second spring 138, the cross bar 137 moves upwards and drives the vertical bar 139 to move upwards, the vertical bar 139 moves upwards and drives the blocking block 1310 to move upwards, so that the lower blocking block 1310 blocks the discharge hole of the charging box 134, further, the sesame in the charging box 134 falls onto the lower blocking block 1310, when the ball 132 rotates to be in contact with the cross bar 137, the ball 132 drives the cross bar 137 to move downwards, the second spring 138 is compressed, the cross bar 137 moves downwards and drives the vertical bar 139 to move downwards, the vertical bar 139 moves downwards and drives the blocking block 1310 to move, when the lower block 1310 moves downwards to the outside of the charging box 134, sesame falls downwards into the screening frame 9, the upper block 1310 blocks the discharge hole of the charging box 134, the sesame in the charging box 134 falls into the screening frame 9 a little bit along with the continuous contact and separation of the rolling ball 132 and the cross bar 137, and after the whole sesame screening is completed, the driving motor 121 is closed, and the block 1310 stops moving up and down. So, can avoid being equipped with a large amount of sesames in the screen frame 9 and influence screening efficiency.
When needs carry out the sesame screening, will collect the frame and remove to discharging pipe 3 left side below, promote to collect the frame and remove right, make and collect frame right side and the contact of driving lever 15 lower part, collect frame and remove right promotion driving lever 15 and swing right, driving lever 15 swings right and drives striker plate 14 downswing, torsion spring 16 is tensile, striker plate 14 downswing does not block the export of discharging pipe 3, and then the sesame in the box 2 falls into from discharging pipe 3 and collects in the frame, after collecting the frame and filling up the sesame, will collect the frame and take up not contact with driving lever 15, under torsion spring 16's effect, striker plate 14 upswing resets, and then drive driving lever 15 and reset. After the sesame in the collecting frame is poured out completely, the collecting frame is placed at the lower left side of the discharging pipe 3 according to the operation, so that the baffle plate 14 does not block the outlet of the discharging pipe 3, and the sesame falls into the collecting frame. So, can prevent to collect when the frame takes off that the sesame continues to drop to ground and leads to the waste.
When the screening frame 9 moves up and down, the screening frame 9 also drives the sleeve 17 to move up and down, the sleeve 17 moves up and down to drive the steel ball 20 to move up and down, the steel ball 20 moves up and down to drive the movable plate 19 to swing up and down, and the movable plate 19 swings up and down to stir the sesame in the screening frame 9. When the screen frame 9 stops moving up and down, the movable plate 19 stops swinging up and down. So, make the better sesame drop to in the box 2 through screening frame 9.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
