Title:
SPEED CONTROL MECHANISM OF SEEDER FOR RAISING SEEDLING
Document Type and Number:
Japanese Patent JP3821504
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a speed control mechanism designed to making the seeding level on raising seedling boxes constant by a treatment capacity regulator even if the capacity of a raising seedling seeder is changed.
SOLUTION: In the raising seedling seeder made up of a bad soil mechanism 1 to be driven by a driving motor 6, a seeder 2 to be driven by a driving motor 7, a soil covering machine 3 to be driven by a driving motor 8, and a conveyer 19 to be driven by a driving motor 9, a 1st invertor controlling and driving the motors 6, 8, 9 and a 2nd invertor controlling and driving the motor 7, and both the 1st and 2nd invertors are made to carry out proportional control.
