Automatic calibration device and method for seeding quantity and fertilizing quantity of seeder

Abstract

The invention relates to an automatic calibration device for the seeding quantity and the fertilizing quantity of a seeder. A power part capable of rotating forwards and reversely is provided with two-side power output ends, one side is connected with an operation row seed-metering and fertilizer-discharging part through a first transmission one-way bearing, and the other side is connected with a calibration seed-metering and fertilizer-discharging part through a second transmission one-way bearing; the locking directions and the free rotation directions of the first transmission one-way bearing and the second transmission one-way bearing are opposite; a seed-receiving and fertilizer-receiving box is arranged below the calibration seed-metering and fertilizer-discharging part, and a load-bearing sensor is arranged on the lower portion of the seed-receiving and fertilizer-receiving box; a matched control system is connected with the load-bearing sensor and the power part; and a comparator is used for comparing the target seeding quantity or fertilizing quantity with a value measured by the load-bearing sensor, and the control system adjusts the relative working rotating speed of a driving motor according to a corresponding proportion, so that the seed-metering quantity and the fertilizing quantity reach target values. The automatic calibration device can be used on the seeder driven by a motor to meter seeds and discharge fertilizers, is matched with a calibration control system, and can realize on-line automatic rapid calibration.

Description

technical field [0001] The invention relates to a device and method for automatically calibrating the seeding amount and fertilization amount of a seeder, and belongs to the technical field of agricultural machinery. Background technique [0002] The fertilizing seeder in the prior art does not have the online automatic calibration function of seeding rate and fertilization rate. 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. 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, the working parts do not touch the ground, a...

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

[0003] Therefore, in the existing calibration method, it takes a long time to calibrate the tool 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
