Automatic calibration control system and method for seeding quantity and fertilizing quantity of precision seeder

Abstract

The invention relates to an automatic calibration control system for seeding quantity and fertilizing quantity of a precision seeder. A power component capable of rotating positively and negatively is provided with double-side power output ends; one side is connected with an operation row seed and fertilizer-discharging component through a first transmission one-way bearing, and the other side is connected with a calibration seed and fertilizer-discharging component through a second transmission one-way bearing; the locking directions of the first transmission one-way bearing and the second transmission one-way bearing are opposite, and the free rotation directions of the first transmission one-way bearing and the second transmission one-way bearing are opposite; a weighing and collecting module is arranged below each seed and fertilizer-discharging component; the power component is provided with a speed acquisition module and a seeding stepping driver; and a CPU module serves as a control center of the whole control system and is in signal connection with the speed acquisition module, the seeding stepping driver and the weighing and collecting module. By means of the control system, calibration is carried out in an on-line manner, and operation is easy and convenient. Calibration can be completed in a short time, calibration can be completed through one key, manual weighing is not needed, and manual input of weighing data is not needed.

Description

technical field [0001] The invention relates to a seeder, in particular to an automatic calibration control system and control method for the seeding rate and fertilization rate of a precision seeder. Background technique [0002] There is a certain deviation between the calibration value of the seeding rate and fertilization rate of the fertilization seeder and the actual value in practical application. [0003] After the user determines the sowing rate and fertilization rate per acre according to the local agronomic requirements, set the sowing rate and fertilization rate of the seeder according to the reference settings given by the planter manufacturer. In order to achieve a more accurate amount, it is necessary to calibrate the actual seed and fertilizer output of the seeder. [0004] At present, the following method is usually used for calibration: park the planter on the field, lift the planter by a tractor or use a support to keep the planter in a suspended state, t...

Problems solved by technology

It can be seen that the above calibration process is cumbersome and inefficient, and due to the manual adjustment, the error is large

With the development of precision modern agriculture and the development of intelligent agricultural machinery, the existing calibration methods for fertilization and seeding machines cannot meet the development requirements

In the existing calibration method, it takes a long time to calibrate the machine before it goes to the ground, and the operation is complicated, time-consuming and labor-intensive.

Due to the manual completion of weighing, calculation, adjustment and other work, there are large errors, and now the agricultural production has high requirements for the accuracy of the amount of seeding and fertilization per mu, so it usually requires repeated calibration several times to achieve a more accurate target value
