By arranging the electric control system, the operation control of the fertilizer discharging motor 32 and the seed metering motor 31 is realized, and the control and adjustment of the fertilizer discharging amount and the seed metering amount are further realized.
The application process and mechanism of the crawler self-propelled rice and wheat precision fertilizing and seeding all-in-one machine are explained as follows:
required fertilizer and seeds are added into the fertilizer bin 9 and the seed bin 10 respectively, the feed bin cover 8 is covered, and the mu operation amount of the required fertilizer and the mu operation amount of the required seeds are input on the touch screen of the electric cabinet 15 respectively.
The diesel engine 2 is started on the driving platform 1, the power of the diesel engine 2 is transmitted to the rotary cultivator gearbox 7 from the gearbox 3 through the transmission shaft 5, and the rotary cultivating cutter shaft 23 and the rotary cultivating cutter 22 arranged on the rotary cultivator gearbox 7 rotate along with the power; the hydraulic lifting pull rod 4 is controlled to descend the machine height through the three-point suspension mechanism 6 until the working depth of the rotary blade 22 meets the requirement. The job operation starts.
After the operation starts, the electronic velometer arranged in the electric cabinet 15 transmits the speed measurement signal to the programmable logic controller PLC for digital operation processing, and respectively sends a working instruction to the fertilizer discharging motor 32 of the seed discharging motor 31, and the fertilizer discharging motor 32 of the seed discharging motor 31 rotates immediately.
The rotation of the seed metering motor 31 causes the seed metering device drive shaft 30 to rotate synchronously, so that the seed metering device 13 on the Z-direction output shaft of the drive shaft assembly 14 rotates correspondingly, and thus, seeds in the seed bin 10 are conveyed from the seed hopper 26 to the seed metering device 13, pass through the seed dropping pipe 16 and fall into a small ditch opened by the ditch pressing wheel assembly 19. Further, the seed metering speed during operation is related to the vehicle speed, but the unit area seed metering quantity is related to the mu quantity set on the touch screen of the electric cabinet 15, and is not related to the vehicle speed. The concrete description is as follows: the unit area seeding amount is the set mu operation amount, the seeding speed is changed at any time according to the speed of the vehicle, the seeding speed is the rotating speed of the seeding motor, the land wheel rotating speed is the vehicle speed, and the corresponding relation between the rotating speed of the seeding motor and the land wheel rotating speed is calculated according to the set mu operation amount, so the unit area seeding amount is the premise of no change.
The rotation of the fertilizer motor 32 causes the fertilizer applicator drive shaft 27 to rotate synchronously, thereby causing the fertilizer applicator 12 to rotate accordingly, so that fertilizer in the fertilizer bin 9 is discharged from the bottom of the fertilizer applicator 12 by rotation thereof, enters the fertilizer dropping pipe 24, falls on the surface of the soil, and is driven into the soil by the rotary blade 22. Further, the fertilizer discharging speed during operation is related to the vehicle speed, but the fertilizer discharging amount per unit area is related to the mu operation amount set on the touch screen of the electric cabinet 15 and is not related to the vehicle speed. The concrete description is as follows: the fertilizer discharging amount per unit area is the set mu operation amount, the fertilizer discharging speed is changed at any time according to the speed of the vehicle, the fertilizer discharging speed is the rotating speed of the fertilizer discharging motor, the rotating speed of the land wheel is the vehicle speed, and the corresponding relation between the rotating speed of the fertilizer discharging motor and the rotating speed of the land wheel is calculated according to the set mu operation amount, so that the fertilizer discharging amount per unit area is the unchanged premise.
The above can be explained in detail by the following:
the discharge capacity of n fertilizer (seed) discharging devices = the set operation quantity per mu and the sowing (fertilizing) area.
The following formula is then derived:
n*（X*h/500）=N*Y*w/667
wherein X is the rotational speed of a seed (fertilizer) sowing motor, h is the discharge capacity of a seed (fertilizer) sowing device per revolution, 500 is converted into jin, N is the set mu operation amount, Y is the linear speed of a land wheel, w is the sowing (fertilizer) width, and 667 is converted into mu.
Further obtaining a corresponding relation between the rotating speed X of the seed (fertilizer) discharging motor and the linear speed Y of the land wheel:
X=500N*Y*w/（nh667）。
the number N of the seed (fertilizer) metering devices is 12, h is 13.3g, and w is 2.6, so that X = 0.012212N Y, and when N is set to 30 catties, X = 0.36659Y.
When the crawler self-propelled rice and wheat precision fertilizing and seeding all-in-one machine does not run, the hydraulic lifting pull rod 4 is controlled to lift the height of the machine to the highest point through the three-point suspension mechanism 6. When the operation is finished and the machine is put into the hangar, the starting switch of the diesel engine 2 is turned off in sequence, the hydraulic lifting pull rod 4 is controlled to descend the machine to the ground, and the power supply is turned off. The crawler self-propelled rice and wheat precision fertilizing and seeding all-in-one machine can realize in-situ turning and turning by adopting a crawler type, and seeding efficiency is improved. The problem that the existing self-propelled precision seeder is mostly wheel-type and insufficient in walking flexibility can be solved.
