Embodiment 1
[0031] Embodiment 1: as figure 1 Shown, a kind of pneumatic type paddy rice deep topdressing device of the present invention comprises:
[0032] Frame 10, blower fan 8 and fertilizer box 9 are arranged on it;
[0033] The fertilizer box 9 and the fertilizer discharger 11 are all fixed on the frame 10, the fertilizer outlet of the fertilizer box 9 is connected to the fertilizer discharger 11, the fertilizer discharger 11 is connected to the fertilizer delivery branch pipe 13, and the lower end of the fertilizer delivery branch pipe 13 extends into the fertilizer discharge supervisor ;
[0034] The blower fan 8 and the pressure-stabilizing distribution chamber 7 are all placed on the frame 10, and its air outlet is connected to the gas pipeline 3 through the pressure-stabilizing distribution chamber 7, and the gas pipeline 3 is connected to the fertilizer discharge supervisor; this example is on the gas pipeline 3 A valve 4 is provided for adjusting the gas flow;
[0035] The...
Embodiment 2
[0046] Embodiment 2: In this embodiment, on the basis of Embodiment 1, a parallel four-bar mechanism 5 is also connected between the air pipeline 3 and the frame 10, and the air outlet of the fan 8 is also connected to an air stabilizing distribution chamber 7 , the air stabilized distribution chamber 7 and the air pipeline 3 are connected with the air hose 6, and the fertilizer discharge device 11 and the fertilizer branch pipe 13 are connected with the fertilizer discharge hose 12, so that the water separator 1 is profiled along the ground surface. The fertilizer guide plate 17 is tangent to the outlet arc section of the centrifugal separation section 15 .
[0047] Such as figure 2 As shown, the arc center angle α of the arc bend at the lower end of the fertilizer transfer branch pipe 13 is 30°; the angle β between the fertilizer transfer branch pipe 13 and the fertilizer transfer main pipe is 55°. The distance H that the end of the fertilizer transfer branch pipe 13 exten...
Embodiment 3
[0049] Embodiment 3: the difference between this example and embodiment 1 is: as figure 2 As shown, the arc center angle α of the arc bend at the lower end of the fertilizer transfer branch pipe 13 in this example is 40°; the angle β between the fertilizer transfer branch pipe 13 and the fertilizer transfer main pipe is 65°. The distance H of the end of the fertilizer transfer branch pipe 13 extending into the fertilizer transfer main pipe is 1 / 4 of the inner diameter of the fertilizer discharge main pipe; the arc corresponding to the central angle θ of the centrifugal separation section 15 is 90°; the length L of the inclined straight pipe ranges from 500mm. The distance S between the upper end of the upper air distribution arc plate 16 and the front part of the fertilizer discharge port 21 is 2 / 3 of the internal diameter of the fertilizer discharge main pipe, which is flush with the fertilizer discharge port 21 . The lower gas distribution arc plate 2 is flush with the bot...
