Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A suction seed disc with adjustable suction volume for a suction seed sowing device is characterized in that a driving shaft 3 is rotatably arranged at the axial central part of a cylindrical closed shell 1, and a driving gear 2 is fixedly arranged at the position, located in a cavity of the cylindrical closed shell 1, of the driving shaft 3; n air holes 5 are uniformly distributed on the end walls of the two opposite ends of the cylindrical closed shell 1 along the circumferential direction at the same turning radius position which takes the axis of the driving shaft 3 as the center of a circle, and are coaxial with the axis; annular seats 7 are fixedly arranged on the inner side wall surface of the end wall of one end of the cylindrical closed shell 1 and are positioned at the outer side positions of the circumferences of the N air holes 5 in a coaxial mode, a plurality of radial sliding grooves 9 are respectively arranged on the outer wall surface of the circumference of each annular seat 7, connecting and mounting pin shafts 6 with air suction quantity adjusting fan-shaped baffle plates 8 are clamped on each radial sliding groove 9 in a sliding mode, the plurality of air suction quantity adjusting fan-shaped baffle plates 8 are in overlapped fit with the corresponding air holes 5 at different radial positions, a plurality of arc-shaped holes 4 with the same number as the radial sliding grooves 9 are uniformly distributed in the circumferential direction on the adjusting gears 10, the N adjusting gears 10 with the same number as the air holes 5 are respectively mounted on the annular seats 7 through the sliding and inserting fit of the connecting and mounting pin shafts 6 and the arc-shaped holes 4, and the N adjusting gears 10 are meshed with the driving gear 2.
When the seed suction disc is used in operation, the N air holes 5 in the end wall of one end of the cylindrical closed shell 1 are respectively communicated with the air suction end of the rotary negative pressure fan, and negative pressure airflow can flow in the N air holes 5 which are coaxial on the end walls of the two ends of the cylindrical closed shell 1 to form negative pressure suction force, so that the adsorption of the seed suction disc with adjustable air suction amount on seeds is completed. When the negative pressure gas flow passing through the air hole 5 needs to be adjusted to adapt to the adjustment of the adsorption force of seeds with different specifications and sizes or seeds of different varieties, the rotating driving shaft 3 drives the adjusting gear 10 to rotate through the driving gear 2, so that the connecting mounting pin shaft 6 moves in the arc-shaped hole 4, meanwhile, the connecting mounting pin shaft 6 synchronously moves in the radial sliding groove 9 on the annular seat 7, the connecting mounting pin shaft 6 drives the suction volume adjusting fan-shaped blocking piece 8 to move in the air hole 5 in the radial direction relative to the air hole 5, the opening size of the air hole 5 is changed, and the adjustment of the negative pressure gas flow is realized.
