The gap between each pair of stalk pulling rollers 143 directly determines the grabbing force of the stalk pulling rollers 143 on corn stalks, the too small gap can lead to the reduction of grabbing force, the stalks are easy to break, the too large gap can lead to the increase of corn kernel loss during picking, and therefore, the corn kernel loss is regulated according to actual harvesting conditions through the spherical hinge 141.
According to the motor-driven ear picking and cutting table mechanism, when the ear picking and cutting table works, the rotating speed of the motor is required to be adjusted according to the dry and wet conditions of corn ears, and if the corn ears are dry buds (the moisture content of the corn ears is low), the rotating speed of the first motor 101 for driving the reel chain 135 is low; when the corn ear is wet bud (the moisture content of the corn ear is high), the first motor 101 drives the rotation speed of the reel chain 135 to be higher; while the rotation speed of the stalk rolls 143 is controlled to be about three times the speed of the reel chain 135 by the first motor.
According to the ear picking and cutting table mechanism based on motor driving, the two groups of independent motors are used for driving the transmission gears to rotate, so that the reel chains and the stalk pulling rollers of the ear picking and cutting table are respectively driven to rotate, corn ear harvesting is realized, the operation quality and the operation efficiency are greatly improved, meanwhile, the reel chains and the stalk pulling rollers are independently driven by matching with different power motors, the different rotation speed requirements of the reel chains and the stalk pulling rollers are realized, the corn ear harvesting efficiency and the corn ear harvesting quality are further improved, and the stability of continuous operation is improved.
