Method for accurately arranging positions and postures of rice seeds

Abstract

The invention relates to a method for accurately arranging positions and postures of rice seeds, belonging to the field of seeding machinery. A flexible annular seed discharging belt of which the surface is provided with a recess is tightened on a plurality of wheels; seeds are partially positioned on the seed discharging belt, and the positioned parts of the seeds are vibrated to enable the seeds to slide into the recess; and the other parts of the seed discharging belt are not vibrated or have small vibration amplitude. When the seed discharging belt rotates along with the wheels, the arranged seeds are transferred to the parts which are not vibrated or have small vibration amplitude; a seed discharging device capable of determining quantities, positions and postures, which is used as aneedle aspiration type seeding machine, or a flexible seed protecting belt (or a flexible carrier) is tightly attached to the parts which are not vibrated on the seed discharging belt, and the seeds are pressed into the recess and synchronously move along with the seed discharging belt; and when the seeds move to the lower part of the seed discharging belt, the seeds are separated from the seed discharging belt and are transferred onto a seeding carrier.

Description

1. Technical Field

[0001] A method for accurately arranging rice seed positions and postures relates to the field of seeding machinery, and specifically relates to a method for arranging seeds for rice sowing. 2. Background technology

[0002] Directional seeding of crops such as rice and corn can make its leaves grow directional or tiller, and make full use of light energy to increase yield. At present, most of the seeding machinery at home and abroad is of the drop type, mainly including slot wheel type, socket type, drawer type, air suction type, needle type and so on. These mechanical seeding precisions are not high and cannot achieve directional seeding. The paste seeding technology invented by me (patent application numbers 200610153983.8, 200720129376.8) can achieve precise positioning and fixed posture seeding (positioning accuracy is on the order of millimeters, fixed posture angle is less than 15 degrees, and quantitative accuracy is greater than 99%), but the operatio...
