Problems solved by technology
At present, the intelligence level of the seed metering devices on the market is low. When the above factors change, it is impossible to achieve precise control of the seeding volume.
At present, the traditional mechanical seed metering device in the existing technology is affected by factors such as the rotational speed, the physical parameters of the rice seed and the seed treatment state, which leads to the problem of low sowing accuracy. The problem of low control accuracy

The invention discloses a rice seed-metering device capable of automatically adjusting the seeding rate. The rice seed-metering device comprises a shell, a stepping motor, a convex gear, a seeding rate adjusting mechanism and a seed-metering shaft. The seeding rate adjusting mechanism comprises a seed-metering wheel, a spring and a volume adjusting cylinder. The seed-metering wheel is mounted in an inner cavity of the shell, the seed-metering wheel is connected with the seed-metering shaft, the seed-metering wheel penetrates through the spring and is connected with the volume adjusting cylinder, one surface, far away from the seed-metering wheel, of the volume adjusting cylinder is connected with the convex gear, and the convex gear is connected with the stepping motor through a motor gear. The seeding rate can be automatically adjusted, and the seeding rate control precision is high.
Description
technical field [0001] The invention relates to the technical field of intelligent agricultural seeding machinery, in particular to a rice metering device for automatically adjusting the sowing rate and an intelligent control system for the sowing rate. Background technique [0002] Rice is one of the three major staple foods in my country and has great strategic value. Rice planting methods are divided into two types: transplanting and direct seeding. The precision hole direct seeding technology is the most important light and simple rice cultivation technology, and its key core component is the seed metering device. [0003] There are many varieties and shapes of rice in my country, and the sowing amount varies greatly due to different varieties, regions, weather, and sowing dates. It is the most difficult to achieve precision sowing among major food crops. In addition, physical characteristic parameters such as the working speed of the seed meter, the triaxial size of th...
