Leveling device of vibrating seed disc of air vibration disc type seedling seeder and balance control method

Abstract

The invention provides a leveling device of a vibrating seed disc of an air vibration disc type seedling seeder and a balance control method, and belongs to the field of agricultural intelligent equipment. The leveling device comprises a rack, the vibrating seed disc, an inclination angle detection platform, an amplitude-adjustable eccentric connecting rod mechanism and a servo electric cylinder,wherein the vibrating seed disc is subjected to amplitude adjustment through the amplitude-adjustable eccentric connecting rod mechanism, and a vibrating seed disc supporting table fixed to the lowerend of the vibrating seed disc is fixed to the inclination angle detection platform provided with a double-shaft inclination angle sensor through a spring; and the inclination angle sensor collects the inclination angle of the inclination angle detection platform and sends the inclination angle to a main control unit, after processing, pulses are output to drive the servo electric cylinder througha servo motor driver, leveling of the inclination angle detection platform is completed, and therefore, the vibrating seed disc is leveled. Different amplitudes of different seeds can be adjusted, and the uniformity of the population boiling effect and the seed suction rate and the seeding effect of the air vibration disc type seedling seeder are improved.

technical field [0001] The invention belongs to the field of agricultural intelligent equipment, and in particular relates to a vibrating seed disc leveling device and a balance control method for an air vibration disc seedling seeder. Background technique [0002] Sowing is an important technical link in the process of agricultural production. In the planting mode of seedling raising and transplanting, seedling raising technology is a key link directly related to whether rice production can achieve high quality, high yield and high efficiency. The seeding device is the main means to realize the mechanized precision seeding technology. The air-suction vibration precision seeding device can meet the unique agronomic requirements of super hybrid rice seedlings such as 2±1 grains / hole, high seedling rate, and strong seedlings. At present, during the vibration process of the seed plate of the air-suction vibrating precision seeding device, due to the mechanical vibration method,...

Problems solved by technology

The inclination angle of the vibrating seed tray of the air vibration disc seedling seeding machine has a great influence on the boiling movement of the population, which in turn affects the seed suction and operation effect of the seedling raising machine, the balance of the vibrating seed tray and the balance of most projects There is a big difference. The balance of the vibrating seed plate is to adjust the balance of the seed plate while the seed plate vibrates back and forth. Most of the engineering balance is to adjust the balance on a static plane, which is much more complicated in comparison.

[0003] In the prior art, a Chinese patent (CN104041229A) discloses an adaptive slanting seed tray mechanism and a control method. The designed self-adaptive slanted seed tray mechanism is relatively complete and can realize the self-adaptive work of the seed tray, but it uses a load cell to detect the seeds Adaptive adjustment based on the distribution of the seed plate requires more sensors and higher cost, and the signal of the load cell is easily affected by electromagnetic interference. At the same time, the adjustment of the amplitude of the vibrating seed plate is very important in practical applications. Able to sow a single seed

Chinese patent (CN208258373U) discloses an adjustable and balanced embedded air suction vibration type precision seeding device. The seeding device has greatly improved the traditional seeding device in terms of structure and vibration mode. Two gears meshing with the seed plate in the Y direction adjust the balance of the seed plate, the balance adjustment accuracy is low, and the seed plate will be affected by the vibration force during the vibration process
