When the field operation is performed, when the rotation external force acts on the rotation shaft 14, the rotation shaft 14 drives the eccentric wheel 12 and the driving chain wheel 15 to perform uniform circular motion together, on one hand, the rotation eccentric wheel 12 is converted into the reciprocating motion of the seed sowing guide rod 11 under the action of the translation frame 13, and the operations of bidirectional seed taking, seed feeding, seed sowing and the like are completed; on the other hand, the driving sprocket 15 drives the driven sprocket 17 to do rotary motion together through the chain 16, the driven sprocket 17 does rotary motion together through the driving brush shaft 10 and the driving brush gear 18, the driving brush gear 18 drives the driven brush gear 19 to do rotary motion in opposite directions, and the driving brush gear 18 and the driven brush gear 19 respectively drive the seed picking brush 20 to finish the removing operation of redundant seeds on the left side and the right side. The specific detailed process is as follows:
1. When the external force of rotation acts on the rotating shaft 14, the rotating shaft 14 drives the eccentric wheel 12 to do uniform circular motion, the eccentric wheel 12 drives the translation frame 13 and the seed metering guide rod 11 to do left-right reciprocating motion, as shown in fig. 3, the left seed metering nozzle 21 is positioned under the left seed metering cavity of the seed metering shell 1, and seed metering operation is performed; the right seed discharging nozzle 21 is positioned at the position of the opening of the middle seed discharging pipe 9, and seeds fall down for seed discharging operation.
2. When the eccentric wheel 12 continues to rotate 180 degrees from the position of fig. 3, the seed metering guide rod 11 translates to the right; firstly, the left seed discharging nozzle 21 carries seeds to pass through the left seed removing brush 20, redundant seeds are removed, the size of the removing amount can be adjusted through the adjusting bolt 4, when the removing amount is adjusted upwards, the removing amount is reduced, and when the removing amount is adjusted downwards, the removing amount is increased; secondly, the seed discharging nozzle 21 carries seeds to pass through the flexible follow-up seed protection belt 22, the flexible follow-up seed protection belt 22 is made of flexible rubber, and the flexible follow-up seed protection belt reciprocates together with the seed discharging guide rod 11 under the friction force of the seed discharging guide rod 11, so that the seeds are protected from abrasion, and the emergence rate of the seeds is ensured; finally, the left seed discharging nozzle 21 carries seeds to the position of the opening of the seed discharging pipe 9, and the seeds fall into the seed discharging pipe 9 under the action of self gravity to finish seed discharging operation; at the same time, the right seed discharging nozzle 21 is positioned under the right seed cavity of the seed discharging shell 1 to perform seed taking operation; the left seed discharging nozzle 21 is positioned at the position of the opening of the middle seed discharging pipe 9, and seeds fall down for seed discharging operation.
3. When the eccentric wheel 12 continues to rotate 180 degrees and returns to the position of fig. 3, the seed metering guide rod 11 translates leftwards; firstly, the seeds are carried by a seed discharging nozzle 21 on the right and pass through a seed picking brush 20 on the right, so that redundant seeds are removed; secondly, the seed discharging nozzle 21 carries seeds through the flexible follow-up seed protecting belt 22; finally, the seed discharging nozzle 21 on the right carries seeds to the position of the opening of the seed discharging pipe 9, and the seeds fall into the seed discharging pipe 9 under the action of self gravity to finish seed discharging operation; at the same time, the left seed discharging nozzle 21 is positioned under the left seed cavity of the seed discharging shell 1 to perform seed taking operation; and then the next round of reciprocating motion is carried out to finish the operations of seed taking, seed feeding, seed discharging, homing and the like.
During field operation, the flow control board 2 can control seed feeding flow, and the function of the flow control board is to ensure that the quantity of seeds at the seed feeding port is sufficient and the pressure is not large, so that when the flow is too large, the pressure at the seed feeding port is too large, and the phenomenon that the seeds at the seed feeding port are "overhead" and cannot be filled is avoided.
During field operation, the seed metering nozzles 21 with different inner diameters can be replaced at any time according to the different seeding amounts so as to meet the requirements of different seeding amounts.
The invention innovatively designs a translation mechanism for driving a seed metering guide rod 11 by a uniform rotation eccentric wheel 12, and has the advantages that: when the seed metering guide rod 11 is driven to reciprocate by the uniform rotation eccentric wheel 12, the transverse displacement speed of the seed metering guide rod 11 is gradually reduced when the seed metering guide rod 11 is horizontally moved to be close to the left seed cavity and the right seed cavity, so that sufficient time for seed taking and seed metering operation can be ensured, and precision seeding can be realized.
The invention innovatively adopts double-side seed taking, and one reciprocating operation of the seed metering guide rod 11 can finish two seed taking and sowing operations, thereby greatly improving the operation efficiency, reducing the abrasion of the seed metering guide rod 11 to the seed metering shell 1 and prolonging the service life.
