Combined seed and fertilizer drill with automatic calibration function

Abstract

The invention relates to a combined seed and fertilizer drill with an automatic calibration function. 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-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 of the first transmission one-way bearing and the second transmission one-way bearing are opposite, and the free rotation directions are opposite; a comparator compares the target seeding quantity or fertilizing quantity with a value measured by a load-bearing sensor, and a control system adjusts the relative working speed of a driving motor according to a corresponding proportion, so that the seeding quantity and the fertilizing quantity reach target values; a seed and fertilizer receiving box and the load-bearing sensor are integrally supported by a discharging shaft, and the discharging shaft is driven by a discharging power part to rotate to drive the seed and fertilizer receiving box to turn over, so that seeds or fertilizers in the seed and fertilizer receiving box are poured out and emptied, and normal calibration of next time is facilitated; and a turnover conical disc device is arranged below a weighing and collecting module.

Description

technical field [0001] The invention relates to a seeder, in particular to a fertilization seeder with an automatic calibration function. 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, and make the seeding shaft or fertilizer shaft rotate at a certain speed evenly....

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
