Abstract

An intelligent self-sequencing rice seedling throwing machine is provided. A seedling box, a first belt seedling conveyor, a second belt seedling conveyor, and a blower are mounted on a chassis. A seedling picker is installed inside the seedling box and is located at the seedling outlet of the seedling box. The first belt seedling conveyor is located below the seedling outlet of the seedling box. The second belt seedling conveyor is located below the first belt seedling conveyor. An air outlet of the blower is located below the point where seedlings fall from the end of the second belt seedling conveyor. A first seedling combing device is installed above the first belt seedling conveyor. Seedlings pass through the gap between the first belt seedling conveyor and the first seedling combing device and fall onto the second belt seedling conveyor.

An intelligent self-sequencing rice seedling throwing machine, comprising:

a chassis on which a seedling box, a first belt seedling conveyor, a second belt seedling conveyor, and a blower are mounted;
and
a seedling picker installed inside the seedling box, the seedling picker being located at a seedling outlet of the seedling box;
the first belt seedling conveyor being located below the seedling outlet of the seedling box;
the second belt seedling conveyor being located below the first belt seedling conveyor;
an air outlet of the blower being located below a point where seedlings fall from an end of the second belt seedling conveyor;
wherein a first seedling combing device is installed above the first belt seedling conveyor;
a rotation direction of the first seedling combing device is opposite to a rotation direction of the first belt seedling conveyor;
a rotation speed of the first seedling combing device is same as a rotation speed of the first belt seedling conveyor;
a rotation speed of the second belt seedling conveyor is same as the rotation speed of the first belt seedling conveyor;
and seedlings pass through a gap between the first belt seedling conveyor and the first seedling combing device and fall onto the second belt seedling conveyor;
a second seedling combing device is installed on the second belt seedling conveyor;
the second seedling combing device is located below a point where seedlings fall from an end of the first belt seedling conveyor;
a rotation direction of the second seedling combing device is same as a rotation direction of the second belt seedling conveyor;
and a rotation speed of the second seedling combing device is less than the rotation speed of the second belt seedling conveyor;
and
a tray extending upward at an incline is installed on the air outlet of the blower;
seedlings leaving the second belt seedling conveyor fall into the tray;
and under an action of air flow from the air outlet of the blower, the seedlings are thrown upward.
