Embodiment Construction

[0026] As shown in FIG. 1 , the motor 1 and the fan 2 are coaxial, and the negative pressure is provided to the seed meter 4 through the suction pipe 3 . It can be seen from Figure 5 that the motor J1 bypasses the battery F, and directly connects with the tractor's self-contained over-frequency generator D before silicon rectification, avoiding the use of complex and expensive DC motors, and obtaining sufficient operating speed. As shown in Figures 2, 3, and 4, the seed meter 4 is composed of a rotating shaft 5, an air suction chamber 6, a seed bowl 7, and a seed box 8. As shown in Figures 6 and 7, the air suction chamber 6 is a A crescent-shaped suction chamber 6 is surrounded above the bottom plate 9, and a through hole is arranged in the suction chamber 6 the inside and is exactly the suction hole 11 connected with the suction pipe 3 outside. On base plate 9 both sides, respectively have a fixing hole 10, as seen in Fig. 4, these two fixing holes 10 respectively connect a f...

Abstract

The present invention relates to agricultural machine assembly, and is especially one kind of electrically driven sucking precise seeder suitable for seeding corn and other crops. The present invention has a reduced induction chamber, a crescent part of the suction disc opposite to the induction chamber, and at most one half of covered sucking holes in the suction disc. Compared with available technology, the present invention has the advantages of reduced required wind rate, low power consumption of the blower and capacity of using the tractor power generator as power source for precise seeding job.

Description

technical field [0001] The invention relates to an agricultural machine part, namely an electric air-suction precision metering device suitable for sowing corn and other crops. Background technique [0002] The precise sowing of corn and other crops can not only save seeds, but also reduce the workload of thinning. However, precision seeding is more difficult and must rely on advanced seeders to achieve. In the 1980s, Dalian Fuzhou Planter Factory successfully developed a large-scale air-suction precision corn planter. The key components of this planter are a seed meter composed of a suction chamber, a seed bowl and a seed box. The power output device of the tractor drives the wind turbine through the transmission mechanism, which creates negative pressure in the suction chamber, absorbs and releases the seeds through the suction cup on the seed bowl, so as to achieve one seed per hole, and the distance between the holes is 1 / 2 of the distance between plants one level. Ho...
