Planters planting planting rate of speed control and automatic control using this method

摘要

Disclosed is a device for controlling a planting speed of a planter and a method for automatically controlling a planting speed using the same. The device of the present invention is equipped with multiple seed and fertilizer containers which are horizontally arranged while being supported on a frame; multiple top discharging units which discharge seeds and fertilizers accommodated in the seed and fertilizer containers while being equipped at the bottom of each seed and fertilizer container; a top drive shaft which operates the top discharging units; a drive motor which rotates the top drive shaft; multiple bottom discharging units which are provided with the seeds and fertilizers discharged from each of the top discharging units through a connecting hose, are operated by means of a bottom drive shaft, and discharge the same to the ground while being disposed at the bottom of each of the top discharging units; and a connecting member which connects the top drive shaft and the bottom drive shaft in order to be geared. The device of the present invention comprises a rotary wheel which is disposed at one side of the frame in order to constantly come in contact with the ground and is rotated according to a driven speed of the planter; a power transmission member which connects a drive shaft of the rotary wheel with a vertically moving shaft installed on the frame to be able to be rotated and transfers rotation power of the drive shaft to the vertically moving shaft; a rotation number sensor which senses the number of rotation of the vertically moving shaft; and a control unit which proportionally controls the number of rotation of the drive motor based on the data about the number of rotation received from the rotation number sensor so that the top drive shaft is proportionally controlled according to a driven speed of the planter.
