It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0015] Example 1
[0016] See Figure 1-2 A novel rotary tillage precision fertilizer seeder includes a rotary tiller 1, a fertilizer applicator 2, and a seeder 3, as well as a walking mechanism 4. The walking mechanism 4 includes a main frame 41, on which a drive wheel 42 is mounted, and on the shaft of the drive wheel 42, a signal sensor 43 is mounted. The seeder 3 and the fertilizer applicator 2 are mounted on the main frame 41, and the rotary tiller 1 is mounted below the fertilizer applicator 2. Both the fertilizer applicator 2 and the seeder 3 are driven by servo motors. The signal sensor 43 and the servo motor are electrically connected to the control system. Specifically, this invention integrates a rotary tiller 1, a fertilizer applicator 2, and a seeder 3 into one unit, simultaneously achieving three functions without requiring equipment replacement, thereby improving operational efficiency, reducing costs, and decreasing the workload of operators. Simultaneously, a signal sensor 43 collects signals, which are then driven by a servo motor and controlled and set by a control system, thus achieving precision seeding. During rotary tillage, the drive wheels 42 rotate synchronously, and the signal sensor 43 collects the rotation signals of the drive wheels, feeding them back to the control system. The control system then controls the servo motors of the fertilizer applicator 2 and the seeder 3, thereby achieving precision seeding.
[0017] See Figure 3 The rotary tiller 1 includes a frame 11, a gearbox 12 on top of the frame 11, and a tractor drive shaft connected to the gearbox 12 for power. A rotary tillage assembly 13 is located on the front side of the frame 11, and a leveling roller 14 is located on the rear side. The rotary tiller 1 is powered by the tractor drive shaft connected to the gearbox 12, performs rotary tillage operations on the field through the rotary tillage assembly 13, and simultaneously crushes and buries straw, weeds, etc. in the field. The leveling roller 14 levels the field after rotary tillage.
[0018] See Figure 4 The fertilizer applicator 2 includes a pair of support frames 21. A fertilizer box 22 is mounted on the top of the support frames 21. The fertilizer box 22 is divided into fertilizer troughs by a partition. Each fertilizer trough has a fertilizer discharge wheel 23 at its bottom, and a fertilizer guide tube 24 is mounted below the fertilizer discharge wheel 23. The fertilizer discharge wheel 23 is driven by a servo motor. Fertilizer is injected into the fertilizer box 22, and the fertilizer discharge wheel 23 is driven by the servo motor to achieve precision fertilization.
[0019] See Figure 5 The seeder 3 includes a support frame 31, with a seed box 32 mounted on top of the support frame 31. A furrowing wheel 33 and a soil-covering wheel 34 are mounted at the bottom of the seed box 32. A seed metering device 35 is installed at the outlet of the seed box 32, driven by a servo motor. A seed metering guide pipe 36 is connected to the outlet of the seed box 31. Seeds are injected into the seed box 32 and discharged through the seed metering device 35, achieving precise discharge under the action of the servo motor. The seeds pass through the seed metering guide pipe 36 and fall into the furrows opened by the furrowing wheel 33. The soil-covering wheel 34 follows the soil-covering operation, burying the seeds in the soil layer.
[0020] Example 2
[0021] The working principle of a novel rotary tillage precision fertilization and seeding system includes the following steps: S1. The rotary tiller is powered by the tractor drive shaft to perform rotary tillage of the field, while crushing and burying straw, weeds and other materials in the field. The leveling roller will level the field after rotary tillage. S2. During rotary tillage, the drive wheels rotate synchronously and move, and the sensors collect the rotation and movement signals of the drive wheels and feed them back to the control system. S3. Manually set the required amount of fertilizer and seeding per acre through the control system. Controlled by the control system signal, the servo motor of the fertilizer applicator is powered on and the fertilizer discharge wheel starts to discharge fertilizer. The fertilizer falls through the fertilizer guide tube to the front of the rotary tiller, and after being tilled by the rotary harrow, it is buried in the soil. S4.
