The driven wheel 2 is driven to rotate through the belt, so the driven wheel 2 drives the coaxially arranged turbine umbrella 3 on the main shaft to rotate clockwise. Since the turbine covers 6 are coaxially arranged on both sides of the turbine umbrella 3, and the two turbines The upper part of the cover 6 is provided with an air outlet 4, the air outlet 4 is connected to the upper interface of a main air pipe 5, the lower interface of the main air pipe 5 is connected to the middle part of the split air cavity box 7, and the rotating wind generated by the turbine umbrella 3 passes through the main air pipe 5 Entering into the distribution air chamber box 7, the rotating wind is diverted through a number of exhaust ports 14 on both sides of the distribution air chamber box 7 and then enters the corresponding seed metering device. The pressure and wind speed in the distribution air chamber box 7 pass 8 The positive and negative pressure gauges 9 on the upper part are recorded to facilitate the adjustment of the rotating speed of the hydraulic motor 11, and the effect of controlling the seeding speed, depth and uniformity of seeding is realized by controlling the pressure and wind speed of the rotating wind.
