Description
Technical Field
The utility model relates to a seeder especially relates to a cotton seeding rate adjusting device.
Background
In the main cotton production area of Hebei province, part of cotton farmers have own habit of reserving seeds for the cotton varieties with better growth vigor in the year, so that the seed purchasing cost can be saved and the yield can be ensured in the second year; in the next year, cotton farmers use the self-remained offspring cotton seeds as seeds, and do not delinter the cotton seeds in view of cost saving, namely, the offspring cotton seed skin keeps a large amount of short fibers; in the seeding process, the cotton seeds stored in the seed box are stirred by the drive plate and fall into soil through the seed dropping port by self gravity, the self-left seeds are adhered due to the increase of friction force of short fibers on the cotton seed hulls, when the conventional cotton seeding machine is used, the cotton seeds cannot easily fall into the seed dropping port like polished seeds, the control is realized only by adjusting the rotating speed of the drive plate in the seed box, and the accurate control of the seed dropping amount is difficult to realize.
