Device and method for automatic calibration of seeding rate and fertilization rate of seeder

Abstract

The invention relates to an automatic calibrating device for seeding rate and fertilizing rate of a planter. A power component that can rotate in both forward and reverse directions has two-sided power output ends; One side is connected with the seed metering and fertilizing part for calibration through the second transmission one-way bearing; the locking direction of the first transmission one-way bearing and the second transmission one-way bearing are opposite to the direction of free rotation; There is an inoculation and fertilizer receiving box under the fertilizer part, and a load-bearing sensor is arranged at the lower part of the inoculation and fertilizer receiving box; the supporting control system is connected with the load-bearing sensor and the power part; the comparator measures the target seeding amount or fertilization amount with the load-bearing sensor The control system adjusts the relative working speed of the drive motor according to the corresponding ratio, so that the amount of seeding and the amount of fertilization reach the target value. It can be used on the planter driven by the motor for seeding and fertilizing, and in cooperation with the calibration control system, it can realize online automatic and 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
