The main reasons are as follows: when the clapboard is adjusted too high, there will be holes. when the scoop wheel scoops the corn seeds, it will fall before the scoop wheel reaches the entrance of the clapboard, causing holes. therefore, there will be uneven corn seedlings and seedling shortage. the broadcast corn seedlings will lack seedlings one by one. one point is to reduce the operation speed.
Before entering the ground, add seeds and rotate the ground wheel to see if there are corn seeds on the spoon wheel and if there are two seeds on the spoon wheel, if the partition board is adjusted too low, the gap in the partition board will be adjusted upwards. if there is an empty spoon wheel that needs to be adjusted downwards, this is the basic adjustment method of the seed metering device. if the gap between the partition board and the spoon wheel is too large, uneven will also occur.
Adjustment method of the seed metering device: Pull out the partition board of the seed metering device outward to unlock the hand ball, and move the partition board up and down to adjust it according to your own needs. After adjustment, you must turn the ground wheel to watch the operation of the spoon wheel of the seed metering device. As mentioned above, only by adjusting the Manual Fertilizer Seeder can you achieve very good seeding effect.
