Problems solved by technology

These problems will cause the ground wheel to slip, and then the uniformity of sowing cannot be guaranteed
[0005] 2. It is difficult to adjust the planting distance
[0006] When adjusting the planting distance, it is necessary to manually calculate the sprocket ratio of the gearbox corresponding to the planting distance, and then manually replace the corresponding sprocket to realize the adjustment of the planting distance. The whole operation process is very complicated, time-consuming and laborious
And this adjustment method can only calculate a limited number of plant spacing, it is difficult to meet the requirements of precision sowing
[0007] 3. Troubleshooting difficulties
[0008] The whole system controls the fertilization and seeding work of the seeder through the mechanical structure. The structure is complex, the operation is difficult, and it is prone to failure.
However, the alarms of traditional planters are generally installed outside the driver's cab. During sowing operations, they can only prompt the driver of the fault, but cannot show the fault location to the driver.
Therefore, when the seeder breaks down, the driver needs to check each part of the seeder one by one before repairing the fault point. The whole process of troubleshooting is very difficult.
[0009] 4. Side row seeding is prone to replay phenomenon
[0010] When planting side by side, the driver needs to get off the car and close part of the metering devices before planting. The operation process is complicated and cumbersome
Moreover, once the seed meter is not closed tightly, reseeding will occur, wasting seeds, and the reseeded plants will need to be pulled out later, adding unnecessary work burden to farmers

Embodiment 1

[0052] Embodiment 1 A planter intelligent control system

[0053] In this embodiment, a stepping motor is used to drive the seed metering device 4 and the fertilizer applicator to rotate, and the control of the stepping motor is realized through a PLC program. During the progress of the seeder, the planting distance and the amount of fertilizer applied per mu can be accurately controlled, thereby achieving precise sowing. requirements.

[0054] like Figure 1 to Figure 2 As shown, this embodiment includes a control unit, an execution unit and a monitoring unit.

[0055] 1. Execution unit

[0056] The execution unit is used to drive the fertilizer applicator and the seed metering device 4 to rotate, so as to complete the work of fertilization and seed metering. The execution unit includes a first drive mechanism and a second drive mechanism respectively connected to the output port of the control unit, wherein the first drive mechanism is power-connected with the seed meter ...

Embodiment 2

[0068] Example 2 A method of precisely controlling the fertilization and seeding of the seeder

[0069] This embodiment utilizes the planter intelligent control system described in Embodiment 1, including the following steps carried out in sequence:

[0070] Step S1, preset parameters

[0071] Start the program, and input the basic parameters and variable parameters into the PLC controller 1. Among them, the variable parameters are planting distance x and fertilization amount y per mu.

[0072] Step S2, real-time measurement of ground wheel speed

[0073] During the running of the seeder, the encoder 11 measures the rotation speed of the ground wheel of the seeder in real time, and transmits the acquired data to the PLC controller 1 . PLC controller 1 through the formula , the calculation of the value measured by the encoder 11 is converted into the internal data of the PLC controller 1.

[0074] Among them: a is the subdivision of the encoder, x is the planting distance...

Embodiment 3

[0094] Example 3 A method of precisely controlling the single planting distance of a planter

[0095] This embodiment mainly describes the control methods of the first program and the second program in the automatic control program of the seeding control module, and the control methods involved in the fertilization control module and the monitoring and alarm module are the same as those in Embodiment 2, so no more details are given here. The following will be explained in conjunction with the specific planting distance:

[0096] Start the first program of the automatic control program in the seeding control module, and set the sowing distance between plants in the first program to be 250mm, and the number of sowing times is 0; at this time, the sowing distance between plants and the number of sowing times in the second program are not all set; Then the first program calculates the internal data to obtain the required number of rotations of the first stepper motor 3; finally th...

Abstract

The invention discloses a planter intelligent control system and a control method thereof, wherein the planter intelligent control system includes a control unit, an execution unit and a monitoring unit; Control program and manual operation program. Also disclosed is a method for accurately controlling the fertilization and seeding of the seeder. First, the encoder in the monitoring unit is used to measure the movement speed of the ground wheel of the seeder in real time; and then the basic parameters, variable parameters and detection data are calculated by the control unit. Analysis; finally, the analysis results are converted into pulse signals to control the execution unit; during the period, the monitoring unit will also monitor the working process of the seeder fertilization and seeding, so as to be able to detect and eliminate faults in time. The present invention can precisely control the planting spacing and the fertilization amount per mu of the planter, and at the same time can realize the sowing operation for any row, saving time and labor, and the sowing is efficient and accurate.

Description

technical field [0001] The invention belongs to the technical field of electric control of agricultural machinery, and relates to the automatic control of fertilization and seeding of a seeder, in particular to an intelligent control system of a seeder and a control method thereof. Background technique [0002] At present, the fertilization and seeding system of domestic seeders is generally driven by the ground wheel, and after being shifted by a manual gearbox, it is connected to the seed metering device or fertilizer applicator through a chain or a transmission shaft to work. Sowing with this control system often has the following deficiencies: [0003] 1. Poor sowing uniformity [0004] The ground wheel drives the seed meter or fertilizer applicator through a multi-stage transmission mechanism, and the ground wheel has a large rotational resistance; and most of the domestic use of no-tillage seeding technology, there are many straws and weeds on the soil surface, and th...
