A Fertilizer Seeder with Automatic Calibration Function

Abstract

The invention relates to a fertilizing and seeding machine with automatic calibration function. The power part which can rotate positively and negatively has double-sided power output ends; The second transmission one-way bearing is connected with the seeding and fertilizer components for calibration; the locking direction of the first transmission one-way bearing and the second transmission one-way bearing are opposite, and the free rotation direction is opposite; the comparator will target the amount of sowing or fertilization Compared with the measured value of 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 seed discharge and fertilization can reach the target value; the inoculation fertilizer box and the load-bearing sensor are supported by the discharge shaft as a whole The unloading shaft is driven and rotated by the unloading power part, which drives the inoculation and fertilizer box to turn over, and pours out the seeds or fertilizer inside, so that the next calibration can be carried out normally; there is a reversible cone device under the weighing acquisition module.

Description

technical field [0001] The invention relates to a seeder, in particular to a fertilization seeder with automatic calibration function. Background technique [0002] The fertilizing seeder in the prior art has no online automatic calibration function of the seeding amount and the fertilizing amount. After the user determines the seeding rate and fertilizing rate per mu according to local agronomic requirements, the seeding rate and fertilizing rate of the seeder are set according to the reference settings given by the seeder manufacturer. In order to achieve a more accurate amount, it is necessary to calibrate the actual seeding and fertilizer amount of the planter. At present, the calibration is usually carried out by the following methods: park the planter on the field, lift the planter by tractor or use a support to make the planter in a suspended state, the working parts do not touch the ground, and make the seeding shaft or fertilizer discharge shaft rotate evenly at 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
