AI Technical Summary

Technical Problem

Existing seeds cannot accurately adjust according to the specific size and shape of the seeds, resulting in high seed damage rate, insufficient seed number, insufficient control of seed depth and spacing, complex structure and not lightweight enough, narrow scope of application, lack of intelligence Inspection and feedback links.

Method used

A small automatic seeder was designed, which uses a combination of mechanical system and control system, including a porous seed disk made of additive manufacturing technology, which can design the hole size and layout density according to the shape of the seeds, and is equipped with a three-flap seed mounter. and infrared sensors realize automated planting and path planning, and control them through STM32 and ESP32 to realize real-time monitoring and fault alarm.

Benefits of technology

It realizes automatic seeding of hole-sowing crops, accurately controls the number of seeds, is suitable for different crops, reduces the weight of the seed machine and the load of the drive motor, improves the accuracy of sowing depth and spacing, and realizes multi-purpose and large-scale planting of one machine. .

Abstract

The invention discloses a small automatic seeder for hole sowing crops, which consists of a mechanical system and a control system, the mechanical system comprises rear wheels, an electric box, a first steering engine, a seed-metering device movement turntable, a translation rod, a seed box, a second steering engine, a front wheel, a first motor, a hose, a seed-metering device, a seed-metering device connecting rod, a second motor, a shell, a steel wire, a seed-metering device fixing ring, an infrared sensor and a frame; the control system comprises a sensing input system and a motion system. According to the device, seeds are tidied before seed metering, and the seed falling number is accurately controlled; the three-petal type seed-metering device is adopted, so that the device can be used for soil with relatively high hardness, and integration of hole digging, seed burying and soil covering is realized; the porous seed tray is manufactured through 3D printing, the design is more reasonable, manufacturing is more convenient and faster, multiple purposes can be achieved by replacing the seed tray, and planting of different crops and different planting requirements are met; path planning is performed according to the initial design, and the seeding depth and spacing are adjusted, so that manpower and material resources are saved, and a scheme is provided for realizing large-scale integrated planting.
