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

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] see Figure 1-Figure 2 , The seeding and fertilizing system on the fertilizing and seeding machine has a seed, 12, a fertilizer box 13, a seeding part 1b, a fertilizer part 1a, a drive motor 3, a drive gearbox 11 and other components.

[0023] Such as figure 1 As shown, the calibration device is also equipped with: the first transmission one-way bearing 2, the second transmission one-way bearing 4, the inoculation fertilizer receiving box 9, the load cell 8, the unloading shaft 5, the unloading gearbox 6, the unloading Material motor 7 and so on. figure 1 Among them, several groups of seeding and fertilizing components on the left side of the drive motor 3 are working row seeding and fertilizing components 1, which are working components for normal sowing and fertilization during work. A group of seed row and fertilizer components on ...

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...
