Example Embodiment
[0007] Specific implementation mode 1: Combination Figure 1 to Figure 10 To explain this embodiment, this embodiment includes a frame 1, a fertilizer box 2, N soil shovel 3, N seeding units, and ground wheels 5; a fertilizer tank 2 is provided above the frame 1, and the fertilizer tank 2 includes a fertilizer storage tank 21 and N fertilizer boxes 22, a fertilizer box 22 is provided on the fertilizer outlet at the lower part of the fertilizer storage box 21, and the soil shovel 3, fertilizer box 22 and seeding unit are sequentially arranged in the moving direction of the frame 1. , The forward direction facility of the frame 1 has N soil shovel 3, and the reverse direction facility of the frame 1 has N seeding units. The seeding unit includes a seeding box 41 and a seed meter 42; also includes a seed meter Drive motor 6, photoelectric encoder 7, drive motor for fertilizer box 8, seed monitoring sensor 9 and controller, power output shaft of seed meter drive motor 6 is coaxially...
Example Embodiment
[0009] Specific implementation manner two: combination Image 6 To illustrate this embodiment, the difference between this embodiment and the above-mentioned specific embodiments is that the photoelectric code disc 7 includes a housing 71, a large gear 72, a small gear 73, a photoelectric encoder 74 and two rolling ball bearings 75; the housing 71 is buckled by two parts. Assembled, each part has a large round hole and a small round hole. A bearing seat is installed on the shaft hole of the large gear 72. The two rolling ball bearings 75 are respectively installed on the bearing seats on both sides of the large gear 72 The two ends of the bearing seat respectively pass through the two large circular holes of the housing 71, the large gear 72 is engaged with the small gear 73, and the signal collection shaft of the photoelectric encoder 74 passes through a small round hole of the housing 71 and the pinion 73 in turn. The shaft hole and the other small round hole of the housing 71...
Example Embodiment
[0010] Specific implementation mode three: combination Figure 8 This embodiment is described. The difference between this embodiment and the above-mentioned specific embodiments is that the seed monitoring sensor 9 includes a sensor housing 91 and a photoelectric counter 92. The four walls of the sensor housing 91 are made of opaque material, and the upper end of the sensor housing 91 is open. In close coordination with the outlet of the seed meter 42, the photoelectric counter 92 is embedded in the housing of the sensor housing 91. The seed monitoring sensor 9 is used to detect and record the number of seeds. The seed monitoring sensor 9 is a photoelectric opaque object detection sensor. Whether soybean or corn seeds are opaque objects, this provides the possibility for the opaque object photoelectric detection sensor to detect the number of seeds; The composition and connection mode are the same as the above-mentioned specific embodiments.
